    A research initiative on embodied artificial intelligence has been launched in 2004 by the Future and Emerging Technologies (FET) arm of the Information Society Technologies (IST) programme of the European Union. The initiative is called "Beyond Robotics" to emphasize that the research projects funded are required to set ambitious objectives and to aim at breakthroughs going well beyond the state of the art. Four projects worth 20 M E of EC funding were selected for 2004-2008 to address the objectives of the initiative.

  2. Local perceptions of intermittent screening and treatment for malaria in school children on the south coast of Kenya

    PubMed Central

    2012-01-01

    Background The intermittent screening and treatment (IST) of school children for malaria is one possible intervention strategy that could help reduce the burden of malaria among school children. Future implementation of IST will not only depend on its efficacy and cost-effectiveness but also on its acceptability to parents of the children who receive IST, as well as those responsible for its delivery. This study was conducted alongside a cluster-randomized trial to investigate local perceptions of school-based IST among parents and other stakeholders on the Kenyan south coast. Methods Six out of the 51 schools receiving the IST intervention were purposively sampled, based on the prevalence of Plasmodium infection, to participate in the qualitative study. Twenty-two focus group discussions and 17 in-depth interviews were conducted with parents and other key stakeholders involved in the implementation of school health programmes in the district. Data analysis was guided by the framework analysis method. Results High knowledge of the burden of clinical malaria on school children, the perceived benefits of preventing clinical disease through IST and previous positive experiences and interactions with other school health programmes facilitated the acceptability of IST. However, lack of understanding of the consequences of asymptomatic parasitaemia for apparently healthy school children could potentially contribute to non-adherence to treatment, and use of alternative anti-malarial drugs with simpler regimens was generally preferred. The general consensus of stakeholders was that health workers were best placed to undertake the screening and provide treatment, and although teachers’ involvement in the programme is critical, most participants were opposed to teachers taking finger-prick blood samples from children. There was also a strong demand for the distribution of mosquito nets to augment IST. Conclusion School-based malaria control through IST was acceptable to most parents and other stakeholders, but careful consideration of the various roles of teachers, community health workers, and health workers, and the use of anti-malarial drugs with simpler regimens are critical to its future implementation.

  3. Cost analysis of school-based intermittent screening and treatment of malaria in Kenya

    PubMed Central

    2011-01-01

    Background The control of malaria in schools is receiving increasing attention, but there remains currently no consensus as to the optimal intervention strategy. This paper analyses the costs of intermittent screening and treatment (IST) of malaria in schools, implemented as part of a cluster-randomized controlled trial on the Kenyan coast. Methods Financial and economic costs were estimated using an ingredients approach whereby all resources required in the delivery of IST are quantified and valued. Sensitivity analysis was conducted to investigate how programme variation affects costs and to identify potential cost savings in the future implementation of IST. Results The estimated financial cost of IST per child screened is US$ 6.61 (economic cost US$ 6.24). Key contributors to cost were salary costs (36%) and malaria rapid diagnostic tests (RDT) (22%). Almost half (47%) of the intervention cost comprises redeployment of existing resources including health worker time and use of hospital vehicles. Sensitivity analysis identified changes to intervention delivery that can reduce programme costs by 40%, including use of alternative RDTs and removal of supervised treatment. Cost-effectiveness is also likely to be highly sensitive to the proportion of children found to be RDT-positive. Conclusion In the current context, school-based IST is a relatively expensive malaria intervention, but reducing the complexity of delivery can result in considerable savings in the cost of intervention. (Costs are reported in US$ 2010). PMID:21933376

    Rodrigues, R. J.

    2000-01-01

    Increasing prominence is being given to the use of best current evidence in clinical practice and health services and programme management decision-making. The role of information in evidence-based practice (EBP) is discussed, together with questions of how advanced information systems and technology (IS&T) can contribute to the establishment of a broader perspective for EBP. The author examines the development, validation and use of a variety of sources of evidence and knowledge that go beyond the well-established paradigm of research, clinical trials, and systematic literature review. Opportunities and challenges in the implementation and use of IS&T and knowledge management tools are examined for six application areas: reference databases, contextual data, clinical data repositories, administrative data repositories, decision support software, and Internet-based interactive health information and communication. Computerized and telecommunications applications that support EBP follow a hierarchy in which systems, tasks and complexity range from reference retrieval and the processing of relatively routine transactions, to complex "data mining" and rule-driven decision support systems.

    This paper examines the images middle school students have of science and technology, the workplaces, and the relevant professions. It also describes the effect on these images caused by an instructional initiative, Investigation into Science and Technology (IST), designed to introduce students to science and technology in the real life. Students' images were delineated via questionnaires, drawing tasks, and interviews before and after their participation in the IST program. The sample consisted of 100 students from six classes (eighth or ninth grade) of three schools. We found that before the IST intervention students' images about the scientific or technological environments were superficial, unreal, and even incorrect. Their impressions of the characteristics of scientists and technologists were superficial, misleading, and sometimes reflected ignorance. The findings demonstrate that the IST program stimulated a positive effect on students' images. Their preconceptions were altered in several dimensions: in the cognitive dimension, from superficial and vague to precise and correct images; in the perceptive dimension, from stereotypic to rational and open-minded images; and in the affective dimension, from negative to positive attitudes.

    The aim of the @neurIST project is to create an IT infrastructure for the management of all processes linked to research, diagnosis and treatment development for complex and multi-factorial diseases. The IT infrastructure will be developed for one such disease, cerebral aneurysm and subarachnoid haemorrhage, but its core technologies will be transferable to meet the needs of other medical areas. Since the IT infrastructure for @neurIST will need to encompass data repositories, computational analysis services and information systems handling multi-scale, multi-modal information at distributed sites, the natural basis for the IT infrastructure is a Grid Service middleware. The project will adopt a service-oriented architecture because it aims to provide a system addressing the needs of medical researchers, clinicians and health care specialists (and their IT providers/systems) and medical supplier/consulting industries.

    The BREAD - co-ordination action, funded by the European Commission through the Framework 6 Programme (FP6) aims at developing a multi-disciplinary approach for the realization of the 'Broadband for All' concept within Europe, bringing together societal, economic, regulatory and technological disciplines and presenting information from regional "success stories" of actual deployment. The EU objective of achieving "Broadband for All" will not be reached by solely a 'technology push' strategy but will need this multi-disciplinary approach and sharing of views and knowledge to develop new strategies and good practice recommendations in the area of 'Broadband for All'. As a co-ordination action the project wants to unite all players active in the field of the end-to-end broadband provisioning for all. It performs a multi-technological analysis of the current and evolving situation, starting from the roadmap information generated by different projects and IST instruments which focus on specific technological domains. The BREAD consortium simultaneously studies the techno-economic, societal and regulatory aspects of this "Broadband for All" concept. It tries to identify the impact of the EU regulatory framework on the successful implementation of new broadband communication services.

    To investigate the efficacy and safety of umbilical cord blood (UCB) infusion (UCBI) plus immunosuppressive therapy (IST) treatment in comparison to IST treatment, as well as predictive factors for clinical responses, in severe aplastic anemia (SAA) patients. Totally, 93 patients with SAA were enrolled in this cohort study. In the IST group, rabbit antithymocyte globulin (r-ATG) combined with cyclosporine A (CsA) was administered, while in the IST+UBCI group, r-ATG, CsA, and UCB were used. After 6 months of treatment, UCBI+IST achieved a higher complete response (CR) rate (p=0.002) and an elevated overall response rate (ORR) (p=0.004), compared to IST. Regarding hematopoietic recovery at month 6, platelet responses in the UCBI+IST group were better than those in the IST group (p=0.002), and UCBI+IST treatment facilitated increasing trends in absolute neutrophil count (ANC) response (p=0.056). Kaplan-Meier curves illuminated UCBI+IST achieved faster ANC response (p<0.001) and platelet response (p<0.001), compared with IST therapy. There was no difference in overall survival (OS) between the two groups (p=0.620). Furthermore, logistic regression analysis demonstrated that UCBI+IST was an independent predicting factor for both CR (p=0.001) and ORR (p<0.001), compared to IST; meanwhile, very severe aplastic anemia (VSAA) and ANC could predict clinical responses as well. However, Cox proportional hazard regression indicated that VSAA (p=0.003), but not UCBI+IST, affected OS. Safety profiles showed that UCBI+IST therapy did not elevate adverse events, compared with IST treatment. UCBI+IST achieved better clinical responses and hematopoietic recovery than IST, and was well tolerated in SAA patients. © Copyright: Yonsei University College of Medicine 2018.

    In an effort to design the next generation Lunar suit, NASA has initiated a series of tests aimed at understanding the human physiological and biomechanical affects of space suits under a variety of conditions. The first of these tests was the EVA Walkback Test (ICES 2007-01-3133). NASA-JSC assembled a multi-disciplinary team to conduct the second test of the series, titled Integrated Suit Test 1 (IST-1), from March 6 through July 24, 2007. Similar to the Walkback Test, this study was performed with the Mark III (MKIII) EVA Technology Demonstrator suit, a treadmill, and the Partial Gravity Simulator in the Space Vehicle Mock-Up Facility at Johnson Space Center. The data collected for IST-1 included metabolic rates, ground reaction forces, biomechanics, and subjective workload and controllability feedback on both suited and unsuited (shirt-sleeve) astronaut subjects. For IST-1 the center of gravity was controlled to a nearly perfect position while the weight, pressure and biomechanics (waist locked vs. unlocked) were varied individually to evaluate the effects of each on the ability to perform level (0 degree incline) ambulation in simulated Lunar gravity. The detailed test methodology and preliminary key findings of IST-1 are summarized in this report.

    Chronic diseases are pressing health systems to introduce reforms, focused on primary care and multidisciplinary models. Community pharmacists have developed a new role, addressing pharmaceutical care and services. Information systems and technologies (IST) will have an important role in shaping future healthcare provision. However, the best way to design and implement an IST for pharmaceutical service provision is still an open research question. In this paper, we present a possible strategy based on the use of Design Science Research Methodology (DSRM). The application of the DSRM six stages is described, from the definition and characterization of the problem to the evaluation of the artefact.

    This paper seeks to explore the development of a discharge programme in one learning disability hospital in Scotland. The study aims to concentrate on organisational developmental changes in that institution. The model of the management during the discharge programme was investigated. The aim of the study is to explore how the discharge programme developed, as seen under the lens of organisational change, in order to find out what kind of model of management is more suitable in similar programmes. A case study was employed. Data were collected by means of interviews. The interviews followed a structured format. The sample of the study had to be a purposive sample and the method of snowball sampling was used; finally, 28 interviews were conducted. A grounded approach was adopted for the data analysis. The software program QSR "NUD*IST" (version "N6") was used as a technical tool, in order to facilitate the data analysis. The findings of this study show that various management models were adopted in the four phases of the discharge programme. These different models represent a "quest" by the institution's management regarding the most appropriate model for managing the discharge programme. This study shows that this goes on continuously in organisations under transition until they settle down to a more permanent state. It was concluded that management models, which are composed of characteristics from the organic theory of organisational management, could apply in discharge programmes. The data gathered enabled the researcher to arrive at a model of management which is suitable for managing organisational changes in discharge programmes, the named "stakeholder management model".

    2003-07-01

    Integration of satellite access networks with the Internet is seen as a strategic goal to achieve in order to provide ubiquitous broadband access to Internet services in Next Generation Networks (NGNs). One of the main interworking aspects which has been most studied is an efficient management of satellite resources, i.e. bandwidth and buffer space, in order to satisfy most demanding application requirements as to delay control and bandwidth assurance. In this context, resource management in DVB-S/DVB-RCS satellite technologies, emerging technologies for broadband satellite access and transport of IP applications, is a research issue largely investigated as a means to provide efficient bi-directional communications across satellites. This is in particular one of the principal goals of the SATIP6 project, sponsored within the 5th EU Research Programme Framework, i.e. IST. In this paper we present a possible approach to efficiently exploit bandwidth, the most critical resource in a broadband satellite access network, while pursuing satisfaction of delay and bandwidth requirements for applications with guaranteed QoS through a traffic control architecture to be implemented in ground terminals. Performance of this approach is assessed in terms of efficient exploitation of the uplink bandwidth and differentiation and minimization of queuing delays for most demanding applications over a time-varying capacity. Opnet simulations is used as analysis tool.

  19. Ultrasound and anatomical assessment of the infraspinatus tendon through anterosuperolateral approach.

    PubMed

    Michelin, Paul; Kasprzak, Kevin; Dacher, Jean Nicolas; Lefebvre, Valentin; Duparc, Fabrice

    2015-08-01

    In the literature, shoulder ultrasound (US) protocols rely on the widely accepted anatomical concept of the infraspinatus tendon (IST) running parallel and posterior to the supraspinatus tendon (SST). To assess the IST, authors currently recommend placing the transducer posteroinferior to the acromion; however the examination of the anterosuperior part of the IST remains problematic. The aim of our study was to apply recent anatomical knowledge to propose a simple protocol to assess the IST over its entire width including its anterosuperior margin. Six non-diseased shoulders from four cadavers were assessed in hyperextended internal rotation (HIR) position with US anterosuperolateral approach followed by dissection. Twelve healthy volunteers underwent similar US examination of the shoulder. The IST is a thin, wide, strap-like tendon. The HIR position exposed the largest area of IST beyond the acromion; combined anterosuperolateral US approach enabled imaging of the IST over its entire width with transverse and longitudinal views. The anterosuperior margin of the IST was distinguishable from the SST. The anterosuperolateral US approach in HIR position enables an accurate assessment of the IST including the transverse plane. The limit between the SST and IST appears more clearly. • The hyperextended internal rotation of the shoulder brings the infraspinatus tendon forward. • The infraspinatus tendon is visible with anterosuperolateral ultrasound approach. • The anterosuperior margin of the infraspinatus tendon is visible with this technique.

  1. Postural tachycardia syndrome and inappropriate sinus tachycardia: role of autonomic modulation and sinus node automaticity.

    Inappropriate sinus tachycardia (IST) and postural tachycardia syndrome (POTS) are 2 disorders characterized by sinus tachycardia. It is debated whether the pathophysiology of IST and POTS results from abnormal autonomic regulation or abnormal sinus node function. We hypothesized that intrinsic heart rate (IHR) after autonomic blockade would be increased in patients with IST but not POTS. We enrolled 48 POTS patients, 8 IST patients, and 17 healthy control (HC) subjects. Intravenous propranolol and atropine were given to block the sympathetic and parasympathetic limbs of the autonomic nervous system in order to determine the IHR. Patients with IST have a higher sympathetic contribution to heart rate when compared with POTS patients (31±13 bpm versus 12±7 bpm, P<0.001) and HC (8±4 bpm; P<0.001) and a trend to less parasympathetic contribution than POTS and HC (IST: 31±11 bpm versus POTS: 46±11 bpm versus HC: 48±11 bpm, ANOVA P=0.108). IHR was not significantly different between IST and either POTS or HC (IST: 111±11 bpm versus POTS: 108±11 bpm versus HC: 106±12 bpm, ANOVA P=0.237). IST patients have more sympathetic tone when compared with either POTS or HC, but IST patients do not have abnormal sinus node automaticity. These data suggest that the treatment of IST and POTS should focus on sympatholysis, reserving sinus node modification for patients with continued debilitating symptoms after beta-blockade and possibly ivabradine. http://clinicaltrials.gov/.

    To increase the adherence of health professionals and cancer survivors to evidence-based physical exercise, effective implementation strategies (ISTs) are required. To examine to what extent these ISTs provide value for money and which IST has the highest expected value. The net benefit framework of health economic evaluations is used to conduct a value-of-implementation analysis of nine ISTs. Seven are directed to health professionals and two to cancer survivors. The analysis consists of four steps: 1) analyzing the expected value of perfect implementation (EVPIM); 2) assessing the estimated costs of the various ISTs; 3) comparing the ISTs' costs with the EVPIM; and 4) assessing the total net benefit (TNB) of the ISTs. These steps are followed to identify which strategy has the greatest value. The EVPIM for physical exercise in the Netherlands is €293 million. The total costs for the ISTs range from €34,000 for printed educational materials for professionals to €120 million for financial incentives for patients, and thus all are cost-effective. The TNB of the ISTs that are directed to professionals ranges from €5.7 million for printed educational materials to €30.9 million for reminder systems. Of the strategies that are directed to patients, only the motivational program had a positive net benefit of €100.4 million. All the ISTs for cancer survivors, except for financial incentives, had a positive TNB. The largest improvements in adherence were created by a motivational program for patients, followed by a reminder system for professionals.

  9. Purification and characterization of FBI-1, a cellular factor that binds to the human immunodeficiency virus type 1 inducer of short transcripts.

    1997-07-01

    The human immunodeficiency virus (HIV-1) promoter directs the synthesis of two classes of RNA molecules, short transcripts and full-length transcripts. The synthesis of short transcripts depends on a bipartite DNA element, the inducer of short transcripts (IST), located in large part downstream of the HIV-1 start site of transcription. IST does not require any viral product for function and is thought to direct the assembly of transcription complexes that are incapable of efficient elongation. Nothing is known, however, about the biochemical mechanisms that mediate IST function. Here, we report the identification and purification of a factor that binds specifically to the IST. This factor, FBI-1, recognizes a large bipartite binding site that coincides with the bipartite IST element. It is constituted at least in part by an 86-kDa polypeptide that can be specifically cross-linked to IST. FBI-1 also binds to promoter and attenuation regions of a number of cellular and viral transcription units that are regulated by a transcription elongation block. This observation, together with the observation that the binding of FBI-1 to IST mutants correlates with the ability of these mutants to direct IST function, suggests that FBI-1 may be involved in the establishment of abortive transcription complexes.

    2015-12-01

    Sit-to-stand exercise (STS) is a common activity of daily living. The objectives of the present study were: 1) to assess the validity of aerobic fitness measurements based on anaerobic thresholds (ATs), during incremental sit-to-stand exercise (ISTS) with and without arm support compared with an incremental cycle-ergometer (CE) test; and 2) to examine the reproducibility of the AT measured during the ISTSs. Twenty-six healthy individuals randomly performed the ISTS and CE test. Oxygen uptakes at the AT (AT-VO2) and heart rate at the AT (AT-HR) were determined during the ISTSs and CE test, and repeated-measures analyses of variance and Tukey's post-hoc test were used to evaluate the differences between these variables. Pearson correlation coefficients were used to assess the strength of the relationship between AT-VO2 and AT-HR during the ISTSs and CE test. Data analysis yielded the following correlations: AT-VO2 during the ISTS with arm support and the CE test, r = 0.77 (p < 0.05); AT-VO2 during the ISTS without arm support and the CE test, r = 0.70 (p < 0.05); AT-HR during the ISTS with arm support and the CE test, r = 0.80 (p < 0.05); and AT-HR during the ISTS without arm support and the CE test, r = 0.66 (p < 0.05). The AT-VO2 values during the ISTS with arm support (18.5 ± 1.9 mL·min(-1)·kg(-1)) and the CE test (18.4 ± 1.8 mL·min(-1)·kg(-1)) were significantly higher than those during the ISTS without arm support (16.6 ± 1.8 mL·min(-1)·kg(-1); p < 0.05). The AT-HR values during the ISTS with arm support (126 ± 10 bpm) and the CE test (126 ± 13 bpm) were significantly higher than those during the ISTS without arm support (119 ± 9 bpm; p < 0.05). The ISTS with arm support may provide a cardiopulmonary function load equivalent to the CE test; therefore, it is a potentially valid test for evaluating AT-VO2 and AT-HR in healthy, young adults. Key pointsThe ISTS is a simple test that varies only according to the frequency of standing up, and requires only a small space and a chair.The ISTS with arm support is valid and reproducible, and is a safe test for evaluating AT in healthy young adults.For evaluating the AT, the ISTS may serve as a valid alternative to conventional CPX, using either a cycle ergometer or treadmill, in cases where the latter methods are difficult to implement.

    We employed next-generation RNA sequencing (RNA-Seq) technology to determine the extent to which exercise training alters global gene expression in skeletal muscle feed arteries and aortic endothelial cells of obese Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Transcriptional profiles of the soleus and gastrocnemius muscle feed arteries (SFA and GFA, respectively) and aortic endothelial cell-enriched samples from rats that underwent an endurance exercise training program (EndEx; n = 12) or a interval sprint training program (IST; n = 12) or remained sedentary (Sed; n = 12) were examined. In response to EndEx, there were 39 upregulated (e.g., MANF) and 20 downregulated (e.g., ALOX15) genes in SFA and 1 upregulated (i.e., Wisp2) and 1 downregulated (i.e., Crem) gene in GFA [false discovery rate (FDR) < 10%]. In response to IST, there were 305 upregulated (e.g., MANF, HSPA12B) and 324 downregulated genes in SFA and 101 upregulated and 66 downregulated genes in GFA, with an overlap of 32 genes between arteries. Furthermore, in aortic endothelial cells, there were 183 upregulated (e.g., eNOS, SOD-3) and 141 downregulated (e.g., ATF3, Clec1b, npy, leptin) genes with EndEx and 71 upregulated and 69 downregulated genes with IST, with an overlap of 35 between exercise programs. Expression of only two genes (Tubb2b and Slc9a3r2) was altered (i.e., increased) by exercise in all three arteries. The finding that both EndEx and IST produced greater transcriptional changes in the SFA compared with the GFA is intriguing when considering the fact that treadmill bouts of exercise are associated with greater relative increases in blood flow to the gastrocnemius muscle compared with the soleus muscle.

    2017-05-01

    To address community needs, the National Institute of Standards and Technology has developed a candidate Standard Reference Material (SRM) for infant/adult nutritional formula based on milk and whey protein concentrates with isolated soy protein called SRM 1869 Infant/Adult Nutritional Formula. One major component of this candidate SRM is the fatty acid content. In this study, multiple extraction techniques were evaluated to quantify the fatty acids in this new material. Extraction methods that were based on lipid extraction followed by transesterification resulted in lower mass fraction values for all fatty acids than the values measured by methods utilizing in situ transesterification followed by fatty acid methyl ester extraction (ISTE). An ISTE method, based on the identified optimal parameters, was used to determine the fatty acid content of the new infant/adult nutritional formula reference material.

    Paraquat poisoning associates very high mortality rate. Early treatment with hemoperfusion is strongly suggested by animal and human studies. Although the survival benefit of additional immunosuppressive treatment (IST) in combination with hemoperfusion is also reported since 1971, the large-scale randomized control trials to confirm the effects of IST is difficult to be executed. Therefore, we designed this nationwide large-scale population-based retrospective cohort study to investigate the outcome of paraquat poisoning with hemoperfusion and the additional effects of IST combined with hemoperfusion. This nationwide retrospective cohort study utilized data retrieved from the National Health Insurance Research Database (NHIRD) of Taiwan. A total of 1811 hospitalized patients with a diagnosis of paraquat poisoning who received hemoperfusion between 1997 and 2009 were enrolled. The mean age of all 1811 study subjects was 47.3 years. 70% was male. The overall survival rate was only 26.4%. Respiratory failure and renal failure were diagnosed in 56.2% and 36% patients. The average frequency of hemoperfusion was twice. IST was added in 42.2% patients. IST significantly increases survival rate (from 24.3% to 29.3%, P<0.001). The combined IST with methylprednisolone, cyclophosphamide and dexamethasone associates with the highest survival rate (48%, P<0.001). Moreover, patients younger than 45 years of age in the IST group had the best survival (41.0% vs. 33.7%, p<0.001). Our results support the use of IST with hemoperfusion for paraquat-poisoned patients. The best survival effect of IST is the combination of methylprednisolone, cyclophosphamide and daily dexamethasone, especially in patients with younger age.

    Paraquat poisoning associates very high mortality rate. Early treatment with hemoperfusion is strongly suggested by animal and human studies. Although the survival benefit of additional immunosuppressive treatment (IST) in combination with hemoperfusion is also reported since 1971, the large-scale randomized control trials to confirm the effects of IST is difficult to be executed. Therefore, we designed this nationwide large-scale population-based retrospective cohort study to investigate the outcome of paraquat poisoning with hemoperfusion and the additional effects of IST combined with hemoperfusion. This nationwide retrospective cohort study utilized data retrieved from the National Health Insurance Research Database (NHIRD) of Taiwan. A total of 1811 hospitalized patients with a diagnosis of paraquat poisoning who received hemoperfusion between 1997 and 2009 were enrolled. The mean age of all 1811 study subjects was 47.3 years. 70% was male. The overall survival rate was only 26.4%. Respiratory failure and renal failure were diagnosed in 56.2% and 36% patients.

    This study analysed the outcome of 563 Aplastic Anaemia (AA) children aged 0-12 years reported to the Severe Aplastic Anaemia Working Party database of the European Society for Blood and Marrow Transplantation, according to treatment received. Overall survival (OS) after upfront human leucocyte antigen-matched family donor (MFD) haematopoietic stem cell transplantation (HSCT) or immunosuppressive treatment (IST) was 91% vs. 87% (P 0·18). Event-free survival (EFS) after upfront MFD HSCT or IST was 87% vs. 33% (P 0·001). Ninety-one of 167 patients (55%) failed front-line IST and underwent rescue HSCT. The OS of this rescue group was 83% compared with 91% for upfront MFD HSCT patients and 97% for those who did not fail IST up-front (P 0·017). Rejection was 2% for MFD HSCT and HSCT post-IST failure (P 0·73). Acute graft-versus-host disease (GVHD) grade II-IV was 8% in MFD graft vs. 25% for HSCT post-IST failure (P < 0·0001). Chronic GVHD was 6% in MFD HSCT vs. 20% in HSCT post-IST failure (P < 0·0001). MFD HSCT is an excellent therapy for children with AA. IST has a high failure rate, but remains a reasonable first-line choice if MFD HSCT is not available because high OS enables access to HSCT, which is a very good rescue option. © 2015 John Wiley & Sons Ltd.

    Idiopathic aplastic anemia (AA) is a rare hematological complication of Down syndrome (DS). The safety and efficacy of immunosuppressive therapy (IST) in individuals with DS remain unknown. We used a standard regimen of IST, comprising antithymocyte globulin and cyclosporine A, to treat three children with DS and idiopathic acquired AA. Two patients achieved a hematological (complete or partial) response and became transfusion independent at the final follow-up. The third patient failed to respond to IST and underwent bone marrow transplantation from a human leukocyte antigen (HLA)-mismatched unrelated donor. None of the patients experienced severe or unexpected adverse events during IST. Our experience suggests that IST is a safe and reasonable treatment, even in individuals with DS who suffer from AA and lack an HLA-matched sibling donor.

    More than three million people in Nigeria are living with HIV/AIDS. In order to reduce the HIV/AIDS burden in Nigeria, the US Government (USG) has dedicated significant resources to combating the epidemic through the President's Emergency Plan for AIDS Relief (PEPFAR). In-service training (IST) of health workers is one of the most commonly used strategies to improve the quality and coverage of HIV/AIDS services. At USAID/Nigeria's request, the USAID-funded CapacityPlus project conducted an assessment of PEPFAR-funded IST for all cadres of health workers in Nigeria. Using the IST Improvement Framework, developed by the USAID Applying Sciences to Strengthen and Improve Systems Project (ASSIST), as a guide, the authors developed a survey tool to assess the efficiency, effectiveness and sustainability of IST provided between January 2007 and July 2012 by PEPFAR-funded implementing partners in Nigeria. The instrument was adapted to the Nigerian context and refined through a stakeholder engagement process. It was then distributed via an online platform to more than 50 PEPFAR-funded implementing partners who provided IST in Nigeria. A total of 39 implementing partners completed the survey. Our survey found that PEPFAR implementing partners have been providing a wide range of IST to a diverse group of health workers in Nigeria since 2007. Most trainings are developed using national curricula, manuals and/or other standard operating procedures. Many of the partners are conducting Training Needs Assessments to inform the planning, design and development of their training programs. However, the assessment also pointed to a number of recommendations to increase the efficiency, effectiveness and sustainability of PEPFAR-funded IST. These actions are as follows: improve collaboration and coordination among implementing partners; apply a more diverse and cost-effective set of training modalities; allocate funding specifically for the evaluation of the effectiveness of training; improve links between IST and both continuing professional development and pre-service education; require implementing partners to create sustainability plans to transition training from PEPFAR funding to other funding sources; and develop a training information management system to track key aspects of IST, such as the number and types of providers, courses, and participants of PEPFAR-funded IST.

    The study investigated how the subjects, 18 children with spastic diplegia aged 7-14 years, attained sit-to-stand (STS). The children were divided into two groups and three STS conditions: 1) those who could attain STS independently (I-STS), 2) those who could not attain STS independently (D-STS), and 3) subjects from the D-STS condition who could successfully attain STS with the walker (W-STS). The results showed that I-STS had more mean maximum horizontal location of the upper body and knee than the hip. All body segments of D-STS followed the same model as the I-STS condition, but they moved with less magnitude than I-STS. W-STS presented both pattern and magnitudes relatively similar to I-STS. Furthermore, I-STS showed the highest mean maximum horizontal and vertical velocities of body segments, when compared with the other STS conditions. W-STS performed the mean maximum horizontal and vertical linear velocities of all selected segments close to D-STS did.

    Surface temperatures on the Greenland Ice Sheet have been studied on the ground, using automatic weather station (AWS) data from the Greenland-Climate Network (GC-Net), and from analysis of satellite sensor data. Using Advanced Very High Frequency Radiometer (AVHRR) weekly surface temperature maps, warming of the surface of the Greenland Ice Sheet has been documented from 1981 to present. We extend and refine this record using higher-resolution Moderate-Resolution Imaging Spectroradiometer (MODIS) data from March 2000 to the present. To permit changes to be observed over time, we are developing a well-characterized monthly climate-data record (CDR) of the "clear-sky" surface temperature of the Greenland Ice Sheet using data from both the Terra and Aqua satellites. We use the MODIS ice-surface temperature (IST) algorithm. Validation of the CDR consists of several facets: 1) comparisons between the Terra and Aqua IST maps; 2) comparisons between ISTs and in-situ measurements; 3) comparisons between ISTs and AWS data; and 4) comparisons of ISTs with surface temperatures derived from other satellite instruments such as the Thermal Emission and Reflection Radiometer. In this work, we focus on 1) and 2) above.

In this work, we focus on 1) and 2) above. First we provide comparisons between Terra and Aqua swath-based ISTs at approximately 14:00 Local Solar Time, reprojected to 12.5 km polar stereographic cells. Results show good correspondence when Terra and Aqua data were acquired within 2 hrs of each other. For example, for a cell centered over Summit Camp (72.58 N, 38.5 W), the average agreement between Terra and Aqua ISTs is 0.74 K (February 2003), 0.47 K (April 2003), 0.7 K (August 2003) and 0.96 K (October 2003) with the Terra ISTs being generally lower than the Aqua ISTs. More precise comparisons will be calculated using pixel data at the swath level, and correspondence between Terra and Aqua IST is expected to be closer. (Because of cloud cover and other considerations, only a few common cloud-free swaths are typically available for each month for comparison.) Additionally, previous work comparing land-surface temperatures (LSTs) from the standard MODIS LST product and in-situ surface-temperature data at Summit Camp on the Greenland Ice Sheet show that Terra MODIS LSTs are about 3 K lower than in-situ temperatures at Summit Camp, during the winter of 2008-09. This work will be repeated using both Terra and Aqua IST pixel data (in place of LST data). In conclusion, we demonstrate that the uncertainties in the CDR will be well characterized as we work through the various facets of its validation.

    We explored the feasibility of unrelated donor haematopoietic stem cell transplant (HSCT) upfront without prior immunosuppressive therapy (IST) in paediatric idiopathic severe aplastic anaemia (SAA). This cohort was then compared to matched historical controls who had undergone first-line therapy with a matched sibling/family donor (MSD) HSCT (n = 87) or IST with horse antithymocyte globulin and ciclosporin (n = 58) or second-line therapy with unrelated donor HSCT post-failed IST (n = 24). The 2-year overall survival in the upfront cohort was 96 ± 4% compared to 91 ± 3% in the MSD controls (P = 0·30) and 94 ± 3% in the IST controls (P = 0·68) and 74 ± 9% in the unrelated donor HSCT post-IST failure controls (P = 0·02).The 2-year event-free survival in the upfront cohort was 92 ± 5% compared to 87 ± 4% in MSD controls (P = 0·37), 40 ± 7% in IST controls (P = 0·0001) and 74 ± 9% in the unrelated donor HSCT post-IST failure controls (n = 24) (P = 0·02). Outcomes for upfront-unrelated donor HSCT in paediatric idiopathic SAA were similar to MSD HSCT and superior to IST and unrelated donor HSCT post-IST failure. Front-line therapy with matched unrelated donor HSCT is a novel treatment approach and could be considered as first-line therapy in selected paediatric patients who lack a MSD. © 2015 John Wiley & Sons Ltd.

  17. SPG20 Protein Spartin Is Recruited to Midbodies by ESCRT-III Protein Ist1 and Participates in Cytokinesis

    Hereditary spastic paraplegias (HSPs, SPG1-46) are inherited neurological disorders characterized by lower extremity spastic weakness. Loss-of-function SPG20 gene mutations cause an autosomal recessive HSP known as Troyer syndrome. The SPG20 protein spartin localizes to lipid droplets and endosomes, and it interacts with tail interacting protein 47 (TIP47) as well as the ubiquitin E3 ligases atrophin-1-interacting protein (AIP)4 and AIP5. Spartin harbors a domain contained within microtubule-interacting and trafficking molecules (MIT) at its N-terminus, and most proteins with MIT domains interact with specific ESCRT-III proteins. Using yeast two-hybrid and in vitro surface plasmon resonance assays, we demonstrate that the spartin MIT domain binds with micromolar affinity to the endosomal sorting complex required for transport (ESCRT)-III protein increased sodium tolerance (Ist)1 but not to ESCRT-III proteins charged multivesicular body proteins 1–7. Spartin colocalizes with Ist1 at the midbody, and depletion of Ist1 in cells by small interfering RNA significantly decreases the number of cells where spartin is present at midbodies. Depletion of spartin does not affect Ist1 localization to midbodies but markedly impairs cytokinesis. A structure-based amino acid substitution in the spartin MIT domain (F24D) blocks the spartin–Ist1 interaction. Spartin F24D does not localize to the midbody and acts in a dominant-negative manner to impair cytokinesis. These data suggest that Ist1 interaction is important for spartin recruitment to the midbody and that spartin participates in cytokinesis. PMID:20719964

    2018-04-01

    In order to improve the subjective and objective quality of degraded images at low sampling rates effectively,save storage space and reduce computational complexity at the same time, this paper proposes a joint restoration algorithm of compressed sensing and two step iterative threshold shrinkage (TwIST). The algorithm applies the TwIST algorithm which used in image restoration to the compressed sensing theory. Then, a small amount of sparse high-frequency information is obtained in frequency domain. The TwIST algorithm based on compressed sensing theory is used to accurately reconstruct the high frequency image. The experimental results show that the proposed algorithm achieves better subjective visual effects and objective quality of degraded images while accurately restoring degraded images.

    The aims of this literature review are to (1) summarise how computer and mobile technology-based health behaviour change applications have been evaluated in unintentional injury prevention, (2) describe how these successes can be applied to injury-prevention programmes in the future and (3) identify research gaps. Studies included in this systematic review were education and behaviour change intervention trials and programme evaluations in which the intervention was delivered by either a computer or mobile technology and addressed an unintentional injury prevention topic. Articles were limited to those published in English and after 1990. Among the 44 technology-based injury-prevention studies included in this review, 16 studies evaluated locally hosted software programmes, 4 studies offered kiosk-based programmes, 11 evaluated remotely hosted internet programmes, 2 studies used mobile technology or portable devices and 11 studies evaluated virtual-reality interventions. Locally hosted software programmes and remotely hosted internet programmes consistently increased knowledge and behaviours. Kiosk programmes showed evidence of modest knowledge and behaviour gains. Both programmes using mobile technology improved behaviours. Virtual-reality programmes consistently improved behaviours, but there were little gains in knowledge. No studies evaluated text-messaging programmes dedicated to injury prevention. There is much potential for computer-based programmes to be used for injury-prevention behaviour change. The reviewed studies provide evidence that computer-based communication is effective in conveying information and influencing how participants think about an injury topic and adopt safety behaviours.

    2007-01-01

    Exercise training is known to enhance skeletal muscle blood flow capacity, with high-intensity interval sprint training (IST) primarily affecting muscles with a high proportion of fast twitch glycolytic fibers. The objective of this study was to determine the relative contributions of new arteriole formation and lumenal arteriolar remodeling to enhanced flow capacity and the impact of these adaptations on local microvascular hemodynamics deep within the muscle. The authors studied arteriolar adaptation in the white/mixed-fiber portion of gastrocnemius muscles of IST (6 bouts of running/day; 2.5 min/bout; 60 m/min speed; 15% grade; 4.5 min rest between bouts; 5 training days/wk; 10 wks total) and sedentary (SED) control rats using whole-muscle Microfil casts. Dimensional and topological data were then used to construct a series of computational hemodynamic network models that incorporated physiological red blood cell distributions and hematocrit and diameter dependent apparent viscosities. In comparison to SED controls, IST elicited a significant increase in arterioles/order in the 3A through 6A generations. Predicted IST and SED flows through the 2A generation agreed closely with in vivo measurements made in a previous study, illustrating the accuracy of the model. IST shifted the bulk of the pressure drop across the network from the 3As to the 4As and 5As, and flow capacity increased from 0.7 mL/min in SED to 1.5 mL/min in IST when a driving pressure of 80 mmHg was applied. The primary adaptation to IST is an increase in arterioles in the 3A through 6A generations, which, in turn, creates an approximate doubling of flow capacity and a deeper penetration of high pressure into the arteriolar network.

    We have developed a climate-quality data record of the clear-sky surface temperature of the Greenland Ice Sheet using the Moderate-Resolution Imaging Spectroradiometer (MODIS) Terra ice-surface temperature (1ST) algorithm. A climate-data record (CDR) is a time series of measurements of sufficient length, consistency, and continuity to determine climate variability and change. We present daily and monthly Terra MODIS ISTs of the Greenland Ice Sheet beginning on 1 March 2000 and continuing through 31 December 2010 at 6.25-km spatial resolution on a polar stereographic grid within +/-3 hours of 17:00Z or 2:00 PM Local Solar Time. Preliminary validation of the ISTs at Summit Camp, Greenland, during the 2008-09 winter, shows that there is a cold bias using the MODIS IST which underestimates the measured surface temperature by approximately 3 C when temperatures range from approximately -50 C to approximately -35 C. The ultimate goal is to develop a CDR that starts in 1981 with the Advanced Very High Resolution (AVHRR) Polar Pathfinder (APP) dataset and continues with MODIS data from 2000 to the present. Differences in the APP and MODIS cloud masks have so far precluded the current IST records from spanning both the APP and MODIS IST time series in a seamless manner though this will be revisited when the APP dataset has been reprocessed. The Greenland IST climate-quality data record is suitable for continuation using future Visible Infrared Imager Radiometer Suite (VIIRS) data and will be elevated in status to a CDR when at least 9 more years of climate-quality data become available either from MODIS Terra or Aqua, or from the VIIRS. The complete MODIS IST data record will be available online in the summer of 2011.

    The HIV-1 promoter directs the synthesis of two classes of transcripts, short, non-polyadenylated transcripts and full-length, polyadenylated transcripts. The synthesis of short transcripts is activated by a bipartite DNA element, the inducer of short transcripts or IST, located downstream of the HIV-1 transcriptional start site, while the synthesis of full-length transcripts is activated by the viral activator Tat. Tat binds to the RNA element TAR, which is encoded largely between the two IST half-elements. Upon activation by Tat, the synthesis of short RNAs is repressed. We have previously purified a factor called FBI-1 (for factor that binds to IST) whose binding to wild-type and mutated ISTs correlated well with the abilities of these ISTs to direct the synthesis of short transcripts. Here, we report the cloning of cDNAs encoding FBI-1. FBI-1 contains a POZ domain at its N-terminus and four Krüppel-type zinc fingers at its C-terminus. The C-terminus is sufficient for specific binding, and FBI-1 can form homomers through its POZ domain and, in vivo, through its zinc finger domain as well. In addition, FBI-1 associates with Tat, suggesting that repression of the short transcripts by Tat may be mediated through interactions between the two factors. PMID:9973611

    Global sea ice products are produced from the Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) on board both the Terra and Aqua satellites. Daily sea ice extent and ice-surface temperature (IST) products are available at 1- and 4-km resolution. Validation activities have been undertaken to assess the accuracy of the MODIS IST product at the South Pole station in Antarctica and in the Arctic Ocean using near-surface air-temperature data from a meteorological station and drifting buoys. Results from the study areas show that under clear skies, the MODIS ISTs are very close to those of the near-surface air temperatures with a bias of -1.1 and -1.2 K, and an uncertainty of 1.6 and 1.7 K, respectively. It is shown that the uncertainties would be reduced if the actual temperature of the ice surface were reported instead of the near-surface air temperature. It is not possible to get an accurate IST from MODIS in the presence of even very thin clouds or fog, however using both the Advanced Microwave Scanning Radiometer-EOS (AMSR-E) and the MODIS on the Aqua satellite, it may be possible to develop a relationship between MODIS-derived IST and ice temperature derived from the AMSR-E. Since the AMSR-E measurements are generally unaffected by cloud cover, they may be used to complement the MODIS IST measurements.

  9. Challenges in Treatment of Inappropriate Sinus Tachycardia.

    Inappropriate Sinus Tachycardia (IST) is a clinical syndrome characterized by a sinus heart rate inexplicably higher than one hundred beats per minute at rest that is associated with symptoms like palpitations, dyspnea or dizziness in the absence of primary causes of tachycardia. The diagnosis requires exclusion of other causes of tachycardia including medications/substances (such as anti-cholinergic, beta-blocker withdrawal, caffeine, and alcohol) or medical conditions (such as panic attacks, pulmonary embolism, fever, hyperthyroidism, hypovolemia, anemia, and pain). Work up should include an EKG to differentiate other causes of tachycardia, 24 hour- Holter monitor if indicated, serum thyroid levels, hemoglobin levels and toxicology screen. Electrophysiological studies are not routinely recommended, but should be considered in certain patients in whom concurrent supraventricular tachycardia is suspected. The underlying pathology in IST is yet to be completely understood. However, it is thought that the causes of IST can be broadly classified into two groups; either as an intrinsic increase in sinus node automaticity or an extrinsic cause. Among extrinsic causes, there is evolving evidence that IgG anti-β receptor antibodies are found in IST causing tachycardia. Managing patients with IST includes lifestyle modification, non-pharmacological and pharmacological interventions. Ivabradine has recently emerged as an effective treatment of IST and was shown to be superior to beta-blockers.

    We retrospectively analysed the outcome of consecutive children with idiopathic severe aplastic anaemia in the United Kingdom who received immunosuppressive therapy (IST) or matched unrelated donor (MUD) haematopoietic stem cell transplantation (HSCT). The 6-month cumulative response rate following rabbit antithymocyte globulin (ATG)/ciclosporin (IST) was 32·5% (95% CI 19·3-46·6) (n = 43). The 5-year estimated failure-free survival (FFS) following IST was 13·3% (95% confidence interval [CI] 4·0-27·8). In contrast, in 44 successive children who received a 10-antigen (HLA-A, -B, -C, -DRB1, -DQB1) MUD HSCT there was an excellent estimated 5-year FFS of 95·01% (95% CI 81·38-98·74). Forty of these children had failed IST previously. HSCT conditioning was a fludarabine, cyclophosphamide and alemtuzumab (FCC) regimen and did not include radiotherapy. There were no cases of graft failure. Median donor chimerism was 100% (range 88-100%). A conditioning regimen, such as FCC that avoids total body irradiation is ideally suited in children. Our data suggest that MUD HSCT following IST failure offers an excellent outcome and furthermore, if a suitable MUD can be found quickly, MUD HSCT may be a reasonable alternative to IST. © 2012 Blackwell Publishing Ltd.

    In September 2010, the first International Scientific Tendinopathy Symposium (ISTS) was held in Umeå, Sweden, to establish a forum for original scientific and clinical insights in this growing field of clinical research and practice. The second ISTS was organised by the same group and held in Vancouver, Canada, in September 2012. This symposium was preceded by a round-table meeting in which the participants engaged in focused discussions, resulting in the following overview of tendinopathy clinical and research issues. This paper is a narrative review and summary developed during and after the second ISTS. The document is designed to highlight some key issues raised at ISTS 2012, and to integrate them into a shared conceptual framework. It should be considered an update and a signposting document rather than a comprehensive review. The document is developed for use by physiotherapists, physicians, athletic trainers, massage therapists and other health professionals as well as team coaches and strength/conditioning managers involved in care of sportspeople or workers with tendinopathy.

    In this study, we characterize the ability of the previously described Infoscitex tent (IST) to capture mosquitoes in comparison to either the Centers for Disease Control Light Trap hung next to individuals under a bed net (LTC) or to human landing catches (HLC). In Senegal, the IST caught 6.14 times the number of Anopheles gambiae sensu lato (s.l.), and 8.78 times the Culex group V mosquitoes as LTC. In one of two locations in Burkina Faso, the IST caught An. gambiae at a rate not significantly different than HLC. Of importance, 9.1–36.1% of HLC caught An. gambiae were blood fed, mostly with fresh blood, suggesting they fed upon the collector, whereas only 0.5–5.0% from the IST had partial or old blood. The IST also caught outdoor biting species in proportions comparable to HLC. The results show this tent provides a safer and effective alternative to the skill-dependent, risky, and laborious HLC method. PMID:25422393

    Decision makers need tools to understand the priorities and to set up benchmarks and track progress in their disaster risk reduction activities, so that they can justify their decisions and investments. In this regard, Megacity Indicator System for Disaster Risk Management (MegaIST), is developed in order to be used in disaster risk management studies, for decision makers and managers to establish right strategies and proper risk reduction actions, enhance resource management and investment decisions, set priorities, monitor progress in DRM and validate decisions taken with the aim of helping disaster oriented urban redevelopment, inform investors about risk profile of the city and providing a basis for dissemination and sharing of risk components with related stakeholders; by Directorate of Earthquake and Ground Research of Istanbul Metropolitan Municipality (IMM). MegaIST achieves these goals by analyzing the earthquake risk in three separate but complementary sub-categories consisting of "urban seismic risk, coping capacity and disaster risk management index" in an integrated way. MegaIST model fosters its analyses by presenting the outputs in a simple and user friendly format benefiting from GIS technology that ensures the adoptability of the model's use. Urban seismic risk analysis includes two components, namely; Physical Risk and Social Vulnerability Analysis. Physical risk analysis is based on the possible physical losses (such as building damage, casualties etc.) due to an earthquake while social vulnerability is considered as a factor that increases the results of the physical losses in correlation with the level of education, health, economic status and disaster awareness/preparedness of society. Coping capacity analysis is carried out with the aim of understanding the readiness of the Municipality to respond and recover from a disaster in Istanbul can be defined both in terms of the Municipality's operational capacities - the capacity of the Municipality in terms of the demand on its resources to respond to emergencies and restore services - as well as functional capacities - the policies and planning measures at the Municipality which lead to reduction of risk and protection of people. Disaster Risk Management Index (DRMI) is used as "control system" within the conceptual framework of MegaIST. This index has been developed to understand impact of corporate governance and enforcement structures and policies on total Urban Seismic Risk and in order to make the performance evaluation. Also, DRMI is composed of macro indicators that are developed in order to monitor progress in reducing disaster risk management of institution. They are presented in four broad indicator groups: Legal and Institutional Requirements, Risk Reduction Implementation and Preparedness Activities, Readiness to Respond and Recover, and Strategy and Coordination. As a result; in MegaIST, with the identification and analysis of physical and social vulnerabilities along with coping capacity and disaster risk management performance indicators; an integrated and analytical decision support system has been established to enhance DRM process and reach to a disaster resilient urban environment.

    Eine Computersimulation ermöglicht es uns, mit annähernd Lichtgeschwindigkeit durch die Tübinger Fußgängerzone zu fahren. Was wir dabei sehen, ist verblüffend: Die Häuser vor uns rücken umso weiter in die Ferne, je mehr wir beschleunigen; gleichzeitig erscheinen die Hauskanten in unserer Nähe immer stärker gekrümmt. Der Grund für diese merkwürdigen Bilder ist die so genannte Aberration: Ein und derselbe Lichtstrahl hat für den fahrenden Beobachter eine andere Richtung als für denjenigen, der am Straßenrand steht. Dieser Effekt ist im Alltag klein. Wenn wir aber in der Simulation fast lichtschnell durch die Tübinger Altstadt rasen, ist er dramatisch groß.

  15. Instructional Storytelling: Application of the Clinical Judgment Model in Nursing.

    PubMed

    Timbrell, Jessica

    2017-05-01

    Little is known about the teaching and learning implications of instructional storytelling (IST) in nursing education or its potential connection to nursing theory. The literature establishes storytelling as a powerful teaching-learning method in the educational, business, humanities, and health sectors, but little exploration exists that is specific to nursing. An example of a story demonstrating application of the domains of Tanner's clinical judgment model links storytelling with learning outcomes appropriate for the novice nursing student. Application of Tanner's clinical judgment model offers consistency of learning experience while preserving the creativity inherent in IST. Further research into student learning outcomes achievement using IST is warranted as a step toward establishing best practices with IST in nursing education. [J Nurs Educ. 2017;56(5):305-308.].

    Dauerhafter Unternehmenserfolg ist nur mit einer fortschrittlichen Instandhaltung zu erzielen. Durch den enormen Kostendruck infolge der Globalisierung und die Innovationssprünge auf der technischen Seite wird auch die Frage nach der modernen Organisationsform für die Instandhaltung gestellt. Eine Möglichkeit der Kostenoptimierung ist das Outsourcing von Instandhaltungsleistungen. Hierbei ist es unerlässlich, dass sich die Mitarbeiter zum Dienstleister entwickeln. In diesem Beitrag wird die Entwicklung der InfraServ Knapsack von einer internen Instandhaltungsabteilung hin zu einem Industriellen Dienstleister beschrieben und Aspekte der Zusammenarbeit mit externen Kunden aus der Sicht des outgesourcten Instandhalters geschildert. Es werden die wichtigen Entwicklungsschritte zur Dienstleistungsorientierung der früheren Eigeninstandhaltung aufgezeigt. Dieser Beitrag ist nicht als "Königsweg“ zu verstehen, er soll vielmehr anhand der Erfahrungen einer outgesourcten Eigeninstandhaltung Anregungen für die Entwicklung der eigenen Instandhaltungsorganisation liefern.

  20. Toxoplasma gondii TgIST co-opts host chromatin repressors dampening STAT1-dependent gene regulation and IFN-γ–mediated host defenses

    2016-01-01

    An early hallmark of Toxoplasma gondii infection is the rapid control of the parasite population by a potent multifaceted innate immune response that engages resident and homing immune cells along with pro- and counter-inflammatory cytokines. In this context, IFN-γ activates a variety of T. gondii–targeting activities in immune and nonimmune cells but can also contribute to host immune pathology. T. gondii has evolved mechanisms to timely counteract the host IFN-γ defenses by interfering with the transcription of IFN-γ–stimulated genes. We now have identified TgIST (T. gondii inhibitor of STAT1 transcriptional activity) as a critical molecular switch that is secreted by intracellular parasites and traffics to the host cell nucleus where it inhibits STAT1-dependent proinflammatory gene expression. We show that TgIST not only sequesters STAT1 on dedicated loci but also promotes shaping of a nonpermissive chromatin through its capacity to recruit the nucleosome remodeling deacetylase (NuRD) transcriptional repressor. We found that during mice acute infection, TgIST-deficient parasites are rapidly eliminated by the homing Gr1+ inflammatory monocytes, thus highlighting the protective role of TgIST against IFN-γ–mediated killing. By uncovering TgIST functions, this study brings novel evidence on how T. gondii has devised a molecular weapon of choice to take control over a ubiquitous immune gene expression mechanism in metazoans, as a way to promote long-term parasitism.

    2009-01-01

    Objectives Exercise training is known to enhance skeletal muscle blood flow capacity, with high-intensity interval sprint training (IST) primarily affecting muscles with a high proportion of fast twitch glycolytic fibers. The objective of this study was to determine the relative contributions of new arteriole formation and lumenal arteriolar remodeling to enhanced flow capacity and the impact of these adaptations on local microvascular hemodynamics deep within the muscle. Methods The authors studied arteriolar adaptation in the white/mixed-fiber portion of gastrocnemius muscles of IST (6 bouts of running/day; 2.5 min/bout; 60 m/min speed; 15% grade; 4.5 min rest between bouts; 5 training days/wk; 10 wks total) and sedentary (SED) control rats using whole-muscle Microfil casts. Dimensional and topological data were then used to construct a series of computational hemodynamic network models that incorporated physiological red blood cell distributions and hematocrit and diameter dependent apparent viscosities. Results In comparison to SED controls, IST elicited a significant increase in arterioles/order in the 3A through 6A generations. Predicted IST and SED flows through the 2A generation agreed closely with in vivo measurements made in a previous study, illustrating the accuracy of the model. IST shifted the bulk of the pressure drop across the network from the 3As to the 4As and 5As, and flow capacity increased from 0.7 mL/min in SED to 1.5 mL/min in IST when a driving pressure of 80 mmHg was applied. Conclusions The primary adaptation to IST is an increase in arterioles in the 3A through 6A generations, which, in turn, creates an approximate doubling of flow capacity and a deeper penetration of high pressure into the arteriolar network.

    An implantable stimulator-telemeter (IST-12) was developed for applications in neuroprosthetic restoration of limb function in paralyzed individuals. The IST-12 provides 12 stimulation channels and two myoelectric signal (MES) channels. The MES circuitry includes a two-channel multiplexer, preamplifier, variable gain amplifier/bandpass filter, full-wave rectifier, and bin integrator. Power and control signals are transmitted from an external control unit to the IST-12 through an inductive link. Recorded MES signals are telemetered back to the external control unit through the same inductive link. Following bench testing, one device was implanted chronically in a dog for 15 months and evaluated. Conditions were identified in which MES could be recorded with minimal stimulus artifact. The ability to record MES in the presence of stimulation was verified, confirming the potential of the IST-12 to be used as a myoelectric controlled neuroprosthesis.

    Während bisher der Zusammenhang zwischen Dehydrierung und Phosphorylierung im Licht nur für die stöchiometrischen Chinonreactionen bewiesen worden war, ist nunmehr auch für die katalytischen Chinonreactionen, die aeroben wie die anaeroben, gezeigt worden, dass die Dehydrierung die Phosphorylierung bewirkt. Eine andere Phosphorylierung, als die Phosphorylierung durch Dehydrierung gibt es in den grünen Grana nicht. Natürlich entsteht nunmehr die Frage, welche Substanz das Substrat von Dehydrierung und Phosphorylierung ist. Da die Grana keine Dunkelatmung haben und deshalb im Dunkeln nicht phosphorylieren können, auch nicht nach Zusatz von Chinon, so muss das gesuchte Substrat im Licht entstehen; und da der Photolyt der Granareactionen eine Kohlensäureverbindung ist, so muss das gesuchte Substrat eine im Licht entstehende Kohlenstoffverbindung sein. Wegen der Gärungen und dem einzigen bisher bekannten chemischen Mechanismus der Phosphorylierung durch Dehydrierung (4) denkt man an Triosephosphat. Aber chemisch ist jeder Aldehyd möglich.

    We present perturbations due to seismo-ionospheric coupling processes in propagation characteristics of sub-ionospheric Very Low Frequency (VLF) signals received at Ionospheric & Earthquake Research Centre (IERC) (Lat. 22.50°N, Long. 87.48°E), India. The study is done during and prior to an earthquake of Richter scale magnitude M = 7.3 occurring at a depth of 18 km at southeast of Kodari, Nepal on 12 May 2015 at 12:35:19 IST (07:05:19 UT). The recorded VLF signal of Japanese transmitter JJI at frequency 22.2 kHz (Lat. 32.08°N, Long. 130.83°E) suffers from strong shifts in sunrise and sunset terminator times towards nighttime starting from three to four days prior to the earthquake. The signal shows a similar variation in terminator times during a major aftershock of magnitude M = 6.7 on 16 May, 2015 at 17:04:10 IST (11:34:10 UT). These shifts in terminator times is numerically modeled using Long Wavelength Propagation Capability (LWPC) Programme. The unperturbed VLF signal is simulated by using the day and night variation of reflection height (h‧) and steepness parameter (β) fed in LWPC for the entire path. The perturbed signal is obtained by additional variation of these parameters inside the earthquake preparation zone. It is found that the shift of the terminator time towards nighttime happens only when the reflection height is increased. We also calculate electron density profile by using the Wait's exponential formula for specified location over the propagation path.

Regimen A, without G-CSF in the whole treatment, was used to treat Group A patients, n = 27; Regimen B, G-CSF, was initiated in Group B, n = 24, before the IST until hematologic recovery; Regimen C, G-CSF, was used together with the IST for Group C patients, n = 24, until hematologic recovery; Regimen D,G-CSF was used for Group D, n = 30, after the end of IST until hematologic recovery. The response rate, relapse rate, mortality, infection rate, infection-related death rate, risk of evolving into MDS/AML, survival rate, factors affecting the time of event-free survival and so on. (1) The response (CR+PR) rates 4, 6, 12 and 24 months after IST of the whole series of 105 SAA children were 50.5% (7.6%+42.9%) , 60.0% (21.9%+38.1%) , 67.6% (38.1%+29.5%) and 69.5% (40.0%+29.5%) respectively. The 2-year survival rate was 90.5%; the follow-up of the patients for 13 years showed that the whole survival rate was 87.6%. (2) The differences of the response rates 4, 6, 12 and 24 months after IST of the 4 groups were not significant (P > 0.05). (3) No significant differences were found in the mortalities 4, 6, 12 and 24 months among the 4 groups (P > 0.05). (4) Of the 105 patients, 4 children had relapsed disease in the period of time from 6 to 24 months after IST. All the four patients belonged to the groups with G-CSF. (5) The use of G-CSF could not decrease the infection period before IST (day) (P = 0.273), and it had no impact on the infection rate after IST (P = 0.066). It did not reduce the rates of septicemia and infectious shock. And to the infection-related death rate no significant conclusion can be made. (6) Follow up of the patients for 13 years, showed that 2 had the evolution to MDS/AML in the 105 patients and the two children belonged to the groups with G-CSF. (7) Kaplan-meier curve analysis did not show any differences in the survival rates of the four groups. (8) Cox regression analysis showed that the use of G-CSF had no benefit to the patients' long term survival. While the age of diagnosis and the infection history before IST were significantly related to the patients' long term survival. The use of G-CSF did not contribute to the early response and could not reduce the infection rate, infection-related death rate and the patients' long term survival. There were no significant differences in the survival rates of the four groups. Attention should be paid to the risk of the evolution to MDS/AML.

    It is unknown whether aging affects predecisional processing, that is, gathering information and evaluating options before making a decision. Here, we investigated information sampling in mild Dementia of Alzheimer's type (DAT) and healthy aging by using the Information Sampling Task (IST). In a first investigation, we compared patients with mild DAT (n = 20) with healthy controls (n = 20) on the IST and several neuropsychological background tests. In a second investigation, healthy older adults (n = 30) were compared with younger adults (n = 30) on the IST and executive-function tasks. Results of the first investigation demonstrated that, in the IST, patients gathered significantly less information, made riskier and less accurate decisions, and showed less reward sensitivity relative to controls. We found a significant correlation between performance on the IST and performance on tests of verbal fluency, working memory, and recognition in patients but not in controls. Results of the second investigation indicated a largely similar performance pattern between healthy older adults and younger adults. There were no significant correlations for both groups between the IST and executive-function tasks. There are no relevant changes with healthy aging in predecisional processing. In contrast, mild DAT significantly affects predecisional information sampling. Thus, the problems shown in patients with mild DAT in decision making might be related to the patients' difficulties in predecisional processing. Decision-making performance in mild DAT might be improved by helping the patients at a predecisional stage to gather sufficient information and evaluate options more accurately.

    2012-09-01

    Thin film technology and surface engineering are nowadays key components for numerous innovative products like efficient windows, flat screens, sensors or hard coatings used in tool coating and automotive applications, as well as products for everyday life. In line with the demands of surface technology, coating technology is also evolving and improving. The latest major technology jump was the introduction of pulse technology in physical vapor deposition. High power impulse magnetron sputtering is the most recent development of pulse sputtering. After approximately a decade of intense academic investigation and development we observe today a transfer of this new technology towards industrial processes. As well as several international activities the international conference on fundamentals and applications of HIPIMS continues the success story of the HIPIMS days, initiated in 2004 at Sheffield Hallam University, UK. Becoming the only international conference especially dedicated to HIPIMS the HIPIMS conference is a venue for industrial and academic exchange on the latest developments in this fast evolving new technology. As a joint undertaking of Sheffield Hallam University SHU, Network of Competence for Industrial Plasma Surface Technology INPLAS and Fraunhofer Institute for Surface Engineering and Thin Films IST the HIPIMS conference was launched in 2010 in Sheffield, UK. With 120 delegates the impact of the new conference was underlined. The growing importance of HIPIMS technology was connected with a growth by nearly 35% to 160 participants in 2011 at the second HIPIMS conference in Braunschweig, DE. The participants were made up of equal numbers from research and development (university and research institutes) and industry. Being a global conference representatives from 25 different countries from all continents attended. The HIPIMS conference is also in joint collaboration with the COST Action MP0804 Highly Ionized Pulse Plasma Processes (www.hipp-cost.eu). COST (European Cooperation in Science and Technology) is one of the longest-running European frameworks supporting cooperation among scientists and researchers across Europe (www.cost.eu). The COST Action MP0804 HIPP processes focuses on the fundamentals and the industrial implementation of highly ionized pulse plasmas, where HIPIMS is the most prominent and most mature technology, today. Over 50 high level contributions, divided in 37 oral and 14 poster presentations were highly appreciated by the professional audience. The message from 2011 was that HIPIMS technology has now reached industry. In the opening session of the conference representatives from different companies reported on the latest developments in industrialization. Using HIPIMS technology, the lifetime of mills using a state of the art coating can be extended by 50%. Comparable deposition rates for coating cutting inserts on the different faces are reported. The ice-free window for automotive application is one solution just becoming available by HIPIMS technology. The talks from international experts covered a range from fundamental physics, experimental investigations, theoretically modeling to several applications and made the international conference on fundamentals and applications a success story to be continued in the following years.

    This paper presents an overview of computerised decision support for clinical practice. The concept of computer-interpretable guidelines is introduced in the context of the @neurIST project, which aims at supporting the research and treatment of asymptomatic unruptured cerebral aneurysms by bringing together heterogeneous data, computing and complex processing services. The architecture is generic enough to adapt it to the treatment of other diseases beyond cerebral aneurysms. The paper reviews the generic requirements of the @neurIST system and presents the innovative work in distributing executable clinical guidelines.

    Die Nachweise einer schadlosen Ableitung von Abwässern lassen sich bis weit in die Vergangenheit zurückverfolgen. Sie waren bereits zur damaligen Zeit eine Forderung zur Pflege der öffentlichen Reinlichkeit. Der Kanalisationsbau ist auch immer ein Ausdruck der Kultur eines Volkes gewesen. So kann festgestellt werden, dass im Zusammenhang mit der Hochkultur eines Volkes auch der Kanalbau ein vorherrschendes Thema war. Der Kanalbau steht auch in einem engen Zusammenhang mit dem Wasserleitungsbau. Es ist nur logisch, dass dort wo Wasser teilweise aus großer Entfernung herangeführt worden ist, dieses dann nach Gebrauch auch wieder schadlos beseitigt werden musste.

  14. The soliton transform and a possible application to nonlinear Alfven waves in space

    1993-01-01

    The inverse scattering transform (IST) based on the derivative nonlinear Schroedinger (DNLS) equation is applied to a complex time series of nonlinear Alfven wave data generated by numerical simulation. The IST describes the long-time evolution of quasi-parallel Alfven waves more efficiently than the Fourier transform, which is adapted to linear rather than nonlinear problems. When dissipation is added, so the conditions for the validity of the DNLS are not strictly satisfied, the IST continues to provide a compact description of the wavefield in terms of a small number of decaying envelope solitons.

    Manufacturers of field programmable gate arrays (FPGAS) take different technological and architectural approaches that directly affect radiation performance. Similar y technological and architectural features are used in related technologies such as programmable substrates and quick-turn application specific integrated circuits (ASICs). After analyzing current technologies and architectures and their radiation-effects implications, this paper includes extensive test data quantifying various devices total dose and single event susceptibilities, including performance degradation effects and temporary or permanent re-configuration faults. Test results will concentrate on recent technologies being used in space flight electronic systems and those being developed for use in the near term. This paper will provide the first extensive study of various configuration memories used in programmable devices. Radiation performance limits and their impacts will be discussed for each design. In addition, the interplay between device scaling, process, bias voltage, design, and architecture will be explored. Lastly, areas of ongoing research will be discussed.

    Plant root-associated rhizobacteria elicit plant immunity referred to as induced systemic tolerance (IST) against multiple abiotic stresses. Among multibacterial determinants involved in IST, the induction of IST and promotion of growth by putative bacterial volatile compounds (VOCs) is reported in the present study. To characterize plant proteins induced by putative bacterial VOCs, proteomic analysis was performed by MALDI-MS/MS after exposure of soybean seedlings to a new strain of plant growth promoting rhizobacteria (PGPR) Pseudomonas simiae strain AU. Furthermore, expression analysis by Western blotting confirmed that the vegetative storage protein (VSP), gamma-glutamyl hydrolase (GGH) and RuBisCo large chain proteins were significantly up-regulated by the exposure to AU strain and played a major role in IST. VSP has preponderant roles in N accumulation and mobilization, acid phosphatase activity and Na(+) homeostasis to sustain plant growth under stress condition. More interestingly, plant exposure to the bacterial strain significantly reduced Na(+) and enhanced K(+) and P content in root of soybean seedlings under salt stress. In addition, high accumulation of proline and chlorophyll content also provided evidence of protection against osmotic stress during the elicitation of IST by bacterial exposure. The present study reported for the first time that Ps. simiae produces a putative volatile blend that can enhance soybean seedling growth and elicit IST against 100 mmol l(-1) NaCl stress condition. The identification of such differentially expressed proteins provide new targets for future studies that will allow assessment of their physiological roles and significance in the response of glycophytes to stresses. Further work should uncover more about the chemical side of VOC compounds and a detailed study about their molecular mechanism responsible for plant growth. © 2015 The Society for Applied Microbiology.

    To assess corticosteroid- and immunosuppressive therapy (IST)-free long-term remission in the treatment of patients with sympathetic ophthalmia (SO), a vision-robbing disease that can span a lifetime. The medical records of 19 patients with SO aged 16.1 to 94.95 years (median age 58.56 years) with median follow-up of 7.10 years (mean, 6.41; range, 2.5 to 8.63 years) were retrospectively examined. All patients achieved control of inflammation, 13 of them for 2 years or more. Three (15.78%) of the 19 patients maintained remission without IST and corticosteroids for more than 5 years with vision of 20/25 or better in the sympathizing eye. Thirteen patients (68.42%) were inactive on IST or corticosteroids or in combination therapy. Eleven patients (57.9%) maintained visual acuity of 20/40 or better at the end of follow-up. Even with a devastating and possibly lifelong disease like sympathetic ophthalmia, long-term remission off all IST and corticosteroids, and perhaps even cure, is possible.

    The paper presents the approach to complex training of managers and faculty staff for system modernisation of Russian engineering education. As a methodological basis of design and implementation of the faculty development programme, the CDIO (Conceive-Design-Implement-Operate) Approach was chosen due to compliance of its concept to the purposes and tasks of engineering education development in Russia. The authors describe the structure, the content and implementation technology of the programme designed by Tomsk Polytechnic University and Skolkovo Institute of Science and Technology with the assistance of Chalmers University of Technology and KTH Royal Institute of Technology and other members of the CDIO Initiative. The programme evaluation based on the questionnaire results showed that the programme content is relevant, has high practical value and high level of novelty for all categories of participants. Therefore, the CDIO approach was recommended for implementation to improve various elements of the engineering programme such as learning outcomes, content and structure, teaching, learning and assessment methods. Besides, the feedback results obtained through programme participants' survey contribute to identification of problems preventing development of engineering education in Russia and thus serve as milestones for further development of the programme.

    2016-09-30

    Insecticidal sugar baits for mosquitoes and house ies have proven e cacy to reduce insect populations and consequently, disease transmission rates. The new insecticidal sugar trap (IST) is designed speci cally for controlling biting midge disease vector populations around livestock and near larval habitats. The trap operates by combining light-emitting diode (LED) technology with insecticidal sugar baits. The positive photo attraction of Culicoides elicited by the LEDs, draws the insects to the insecticidal sugar bait, which can be made from various commercial insecticide formulations (pyrethroids, neonicotinoids, etc.) or naturally derived formulations (boric acid, garlic oil, etc.) lethal to Culicoides. Insecticidal sugar trap advantages include: customizable LED lights, they can be used with several di erent oral insecticides that have di erent modes of action to help combat the evolution of pesticide resistance, screening on the trap reduces non-target insect feeding (for example bees and butter ies), targets males and females of the species because both must feed on sugar, and low energy LEDs and a solar panel reduce trap maintenance to re lling sugar baits, rather than replacing batteries. This article discusses key components of an IST, which increase the traps e ectiveness for biting midge control.

    Zygosaccharomyces bailii is one of the most problematic spoilage yeast species found in the food and beverage industry particularly in acidic products, due to its exceptional resistance to weak acid stress. This article describes the annotation of the genome sequence of Z. bailii IST302, a strain recently proven to be amenable to genetic manipulations and physiological studies. The work was based on the annotated genomes of strain ISA1307, an interspecies hybrid between Z. bailii and a closely related species, and the Z. bailii reference strain CLIB 213T. The resulting genome sequence of Z. bailii IST302 is distributed through 105 scaffolds, comprising a total of 5142 genes and a size of 10.8 Mb. Contrasting with CLIB 213T, strain IST302 does not form cell aggregates, allowing its manipulation in the laboratory for genetic and physiological studies. Comparative cell cycle analysis with the haploid and diploid Saccharomyces cerevisiae strains BY4741 and BY4743, respectively, suggests that Z. bailii IST302 is haploid. This is an additional trait that makes this strain attractive for the functional analysis of non-essential genes envisaging the elucidation of mechanisms underlying its high tolerance to weak acid food preservatives, or the investigation and exploitation of the potential of this resilient yeast species as cell factory. © FEMS 2017.

  5. Distinct Mechanisms of Recognizing Endosomal Sorting Complex Required for Transport III (ESCRT-III) Protein IST1 by Different Microtubule Interacting and Trafficking (MIT) Domains*

    PubMed Central

    Guo, Emily Z.; Xu, Zhaohui

    2015-01-01

    The endosomal sorting complex required for transport (ESCRT) machinery is responsible for membrane remodeling in a number of biological processes including multivesicular body biogenesis, cytokinesis, and enveloped virus budding. In mammalian cells, efficient abscission during cytokinesis requires proper function of the ESCRT-III protein IST1, which binds to the microtubule interacting and trafficking (MIT) domains of VPS4, LIP5, and Spartin via its C-terminal MIT-interacting motif (MIM). Here, we studied the molecular interactions between IST1 and the three MIT domain-containing proteins to understand the structural basis that governs pairwise MIT-MIM interaction. Crystal structures of the three molecular complexes revealed that IST1 binds to the MIT domains of VPS4, LIP5, and Spartin using two different mechanisms (MIM1 mode versus MIM3 mode). Structural comparison revealed that structural features in both MIT and MIM contribute to determine the specific binding mechanism. Within the IST1 MIM sequence, two phenylalanine residues were shown to be important in discriminating MIM1 versus MIM3 binding. These observations enabled us to deduce a preliminary binding code, which we applied to provide CHMP2A, a protein that normally only binds the MIT domain in the MIM1 mode, the additional ability to bind the MIT domain of Spartin in the MIM3 mode.

  10. Quality Assurance in Environmental Technology Verification (ETV): Analysis and Impact on the EU ETV Pilot Programme Performance

    NASA Astrophysics Data System (ADS)

    Molenda, Michał; Ratman-Kłosińska, Izabela

    2018-03-01

    Many innovative environmental technologies never reach the market because they are new and cannot demonstrate a successful track record of previous applications. This fact is a serious obstacle on their way to the market. Lack of credible data on the performance of a technology causes mistrust of investors in innovations, especially from public sector, who seek effective solutions however without compromising the technical and financial risks associated with their implementation. Environmental technology verification (ETV) offers a credible, robust and transparent process that results in a third party confirmation of the claims made by the providers about the performance of the novel environmental technologies. Verifications of performance are supported by high quality, independent test data. In that way ETV as a tool helps establish vendor credibility and buyer confidence. Several countries across the world have implemented ETV in the form of national or regional programmes. ETV in the European Union was implemented as a voluntary scheme if a form of a pilot programme. The European Commission launched the Environmental Technology Pilot Programme of the European Union (EU ETV) in 2011. The paper describes the European model of ETV set up and put to operation under the Pilot Programme of Environmental Technologies Verification of the European Union. The goal, objectives, technological scope, involved entities are presented. An attempt has been made to summarise the results of the EU ETV scheme performance available for the period of 2012 when the programme has become fully operational until the first half of 2016. The study was aimed at analysing the overall organisation and efficiency of the EU ETV Pilot Programme. The study was based on the analysis of the documents the operation of the EU ETV system. For this purpose, a relevant statistical analysis of the data on the performance of the EU ETV system provided by the European Commission was carried out.

    To describe how information communication technology (ICT) is being used by programmes that seek to improve private sector health financing and delivery in low- and middle-income countries, including the main uses of the technology and the types of technologies being used. In-country partners in 16 countries directly searched systematically for innovative health programmes and compiled profiles in the Center for Health Market Innovations' database. These data were supplemented through literature reviews and with self-reported data supplied by the programmes themselves. In many low- and middle-income countries, ICT is being increasingly employed for different purposes in various health-related areas. Of ICT-enabled health programmes, 42% use it to extend geographic access to health care, 38% to improve data management and 31% to facilitate communication between patients and physicians outside the physician's office. Other purposes include improving diagnosis and treatment (17%), mitigating fraud and abuse (8%) and streamlining financial transactions (4%). The most common devices used in technology-enabled programmes are phones and computers; 71% and 39% of programmes use them, respectively, and the most common applications are voice (34%), software (32%) and text messages (31%). Donors are the primary funders of 47% of ICT-based health programmes. Various types of ICT are being employed by private organizations to address key health system challenges. For successful implementation, however, more sustainable sources of funding, greater support for the adoption of new technologies and better ways of evaluating impact are required.

Bei persistierender Symptomatik oder Wunsch einer alternativen Behandlung ist eine stratifizierte Diagnostik erforderlich. Alginate und neue Operationsverfahren erweitern die Therapieoptionen.

  14. Der Begriff mathematischer Schönheit in einer empirisch informierten Ästhetik der Mathematik

    NASA Astrophysics Data System (ADS)

    Müller-Hill, Eva; Spies, Susanne

    Dieses Zitat des britischen Mathematikers G. H. Hardy bringt pointiert die unter praktizierenden Mathematikern, aber auch unter Philosophen der Mathematik weithin akzeptierte Ansicht zum Ausdruck, dass mathematische Schönheit eine nicht zu vernachlässigende Rolle in der mathematischen Forschungspraxis spielt und sowohl interessante ästhetiktheoretische, epistemische als auch ontologische Aspekte aufweist. Danach beeinflusst also das Verständnis dessen, was mathematische Schönheit ist, auch das Verständnis dessen, was Mathematik ist: "Was sind die Träger mathematischer Schönheit?" ist die Frage nach der Art der Gegenstände, für deren Schönheit Mathematiker sich begeistern und nach der sie streben. "Was sind die Kriterien für mathematische Schönheit?" ist die Frage nach den Kategorien, unter denen Mathematiker ihre Arbeit bewerten. Egal, ob sich das Phänomen mathematischer Schönheit als Ausnahmemerkmal oder als ständiger Begleiter mathematischen Tuns erweist - ein adäquates allgemeines Mathematikverständnis sollte dieses Phänomen berücksichtigen und bestenfalls auch erklären können.

    Acquired hemophilia A (AHA) is caused by autoantibodies against factor VIII (FVIII). Immunosuppressive treatment (IST) results in remission of disease in 60% to 80% of patients over a period of days to months. IST is associated with frequent adverse events, including infections as a leading cause of death. Predictors of time to remission could help guide IST intensity but have not been established. We analyzed prognostic factors in 102 prospectively enrolled patients treated with a uniform IST protocol. Partial remission (PR; defined as no active bleeding, FVIII restored >50 IU/dL, hemostatic treatment stopped >24 hours) was achieved by 83% of patients after a median of 31 days (range 7-362). Patients with baseline FVIII <1 IU/dL achieved PR less often and later (77%, 43 days) than patients with ≥1 IU/dL (89%, 24 days). After adjustment for other baseline characteristics, low FVIII remained associated with a lower rate of PR (hazard ratio 0.52, 95% confidence interval 0.33-0.81, P < .01). In contrast, PR achieved on steroids alone within ≤21 days was more common in patients with FVIII ≥1 IU/dL and inhibitor concentration <20 BU/mL (odds ratio 11.2, P < .0001). Low FVIII was also associated with a lower rate of complete remission and decreased survival. In conclusion, presenting FVIII and inhibitor concentration are potentially useful to tailor IST in AHA.

    The endosomal sorting complex required for transport (ESCRT) machinery is responsible for membrane remodeling in a number of biological processes including multivesicular body biogenesis, cytokinesis, and enveloped virus budding. In mammalian cells, efficient abscission during cytokinesis requires proper function of the ESCRT-III protein IST1, which binds to the microtubule interacting and trafficking (MIT) domains of VPS4, LIP5, and Spartin via its C-terminal MIT-interacting motif (MIM). Here, we studied the molecular interactions between IST1 and the three MIT domain-containing proteins to understand the structural basis that governs pairwise MIT-MIM interaction. Crystal structures of the three molecular complexes revealed that IST1 binds to the MIT domains of VPS4, LIP5, and Spartin using two different mechanisms (MIM1 mode versus MIM3 mode). Structural comparison revealed that structural features in both MIT and MIM contribute to determine the specific binding mechanism. Within the IST1 MIM sequence, two phenylalanine residues were shown to be important in discriminating MIM1 versus MIM3 binding. These observations enabled us to deduce a preliminary binding code, which we applied to provide CHMP2A, a protein that normally only binds the MIT domain in the MIM1 mode, the additional ability to bind the MIT domain of Spartin in the MIM3 mode. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

  17. Measuring the Surface Temperature of the Cryosphere using Remote Sensing

    A general description of the remote sensing of cryosphere surface temperatures from satellites will be provided. This will give historical information on surface-temperature measurements from space. There will also be a detailed description of measuring the surface temperature of the Greenland Ice Sheet using Moderate-Resolution Imaging Spectroradiometer (MODIS) data which will be the focus of the presentation. Enhanced melting of the Greenland Ice Sheet has been documented in recent literature along with surface-temperature increases measured using infrared satellite data since 1981. Using a recently-developed climate data record, trends in the clear-sky ice-surface temperature (IST) of the Greenland Ice Sheet have been studied using the MODIS IST product. Daily and monthly MODIS ISTs of the Greenland Ice Sheet beginning on 1 March 2000 and continuing through 31 December 2010 are now freely available to download at 6.25-km spatial resolution on a polar stereographic grid. Maps showing the maximum extent of melt for the entire ice sheet and for the six major drainage basins have been developed from the MODIS IST dataset. Twelve-year trends of the duration of the melt season on the ice sheet vary in different drainage basins with some basins melting progressively earlier over the course of the study period. Some (but not all) of the basins also show a progressively-longer duration of melt. The consistency of this IST record, with temperature and melt records from other sources will be discussed.

    Acquired aplastic anemia (aAA) results from the T cell-mediated autoimmune destruction of hematopoietic stem cells. Factors predicting response to immune suppression therapy (IST) or development of myelodysplastic syndrome (MDS) are beginning to be elucidated. Our recent data suggest most patients with aAA treated with IST develop clonal somatic genetic alterations in hematopoietic cells. One frequent acquired abnormality is copy-number neutral loss of heterozygosity on chromosome 6p (6p CN-LOH) involving the human leukocyte antigen (HLA) locus. We hypothesized that because 6p CN-LOH clones may arise from selective pressure to escape immune surveillance through deletion of HLA alleles, the development of 6p CN-LOH may affect response to IST. We used single nucleotide polymorphism array genotyping and targeted next-generation sequencing of HLA alleles to assess frequency of 6p CN-LOH, identity of HLA alleles lost through 6p CN-LOH, and impact of 6p CN-LOH on response to IST. 6p CN-LOH clones were present in 11.3% of patients, remained stable over time, and were not associated with development of MDS-defining cytogenetic abnormalities. Notably, no patient with 6p CN-LOH treated with IST achieved a complete response. In summary, clonal 6p CN-LOH in aAA defines a unique subgroup of patients that may provide insights into hematopoietic clonal evolution. Copyright © 2016 Elsevier Inc. All rights reserved.

    Using the Saccharomyces cerevisiae MATa/MATalpha ORF deletion collection, homozygous deletion strains were identified that undergo mating with MATa or MATalpha haploids. Seven homozygous deletions were identified that confer enhanced mating. Three of these, lacking CTF8, CTF18, and DCC1, mate at a low frequency with either MATa or MATalpha haploids. The products of these genes form a complex involved in sister chromatid cohesion. Each of these strains also exhibits increased chromosome loss rates, and mating likely occurs due to loss of one copy of chromosome III, which bears the MAT locus. Three other homozygous diploid deletion strains, ylr193cDelta/ylr193cDelta, yor305wDelta/yor305wDelta, and ypr170cDelta/ypr170cDelta, mate at very low frequencies with haploids of either or both mating types. However, an ist3Delta/ist3Delta strain mates only with MATa haploids. It is shown that IST3, previously linked to splicing, is required for efficient processing of the MATa1 message, particularly the first intron. As a result, the ist3Delta/ist3Delta strain expresses unbalanced ratios of Matalpha to Mata proteins and therefore mates with MATa haploids. Accordingly, mating in this diploid can be repressed by introduction of a MATa1 cDNA. In summary, this study underscores and elaborates upon predicted pathways by which mutations restore mating function to yeast diploids and identifies new mutants warranting further study.

    Evidence from small case series suggests that the intrasinus thrombolysis (IST) is relatively safe and effective in rapid recanalization of thrombosed sinuses and reversal of neurological deficits in patients with cerebral venous and sinus thrombosis (CVST) However, in the absence of randomized controlled trials, the exact role of IST in the management of CVST is unclear, To study the safety and efficacy of IST in patients with CVST. Adult patients with CVST who received IST during a two-year period (January 2003-December 2004) were included. Data regarding demographic, clinical and radiological features were collected. Follow-up data were obtained at 3-6 months. Magnetic resonance venography (MRV) was repeated to assess the recanalisation of venous sinuses. Nineteen patients (11 women) with a mean age of 32 years (range 17-46 years) received IST during the study period. Common clinical features at presentation included headache, altered consciousness and seizures. Indications for thrombolysis included clinical deterioration despite adequate anticoagulation and rapid worsening of consciousness or neurological deficits. Thirteen patients (68%) had dural sinus thrombosis alone and six others had coexisting deep venous system involvement. Venous infarcts were present in 13 patients. At discharge, 15 patients (79%) had good outcome and were either asymptomatic or had only mild deficits and were independent for activities of daily living. Three patients died and one survived with severe neurological deficits. Angiographic improvement (as per digital subtraction angiography) was noted in 12 patients (complete in five and partial in seven) and seven patients had poor or no recanalization of the involved venous sinuses. At a median follow-up of 6.3 months, 14 (74%) patients had no or mild neurological deficits. IST is safe and effective in patients with CVST who fail to respond to conventional medical treatment. However, the subgroup of patients who are likely to benefit the most from this procedure is not clear from our data. Large randomized controlled trials are required to further clarify this issue.

  3. Relationship between Solvation Thermodynamics from IST and DFT Perspectives.

    Inhomogeneous solvation theory (IST) and classical density functional theory (DFT) each provide a framework for relating distribution functions of solutions to their thermodynamic properties. As reviewed in this work, both IST and DFT can be formulated in a way that use two "end point" simulations, one of the pure solvent and the other of the solution, to determine the solute chemical potential and other thermodynamic properties of the solution and of subvolumes in regions local to the solute containing hydrating waters. In contrast to IST, where expressions for the excess energy and entropy of solution are the object of analysis, in the DFT end point formulation of the problem, the solute-solvent potential of mean force (PMF) plays a central role. The indirect part of the PMF corresponds to the lowest order (1-body) truncation of the IST expression. Because the PMF is a free energy function, powerful numerical methods can be used to estimate it. We show that the DFT expressions for the solute excess chemical potential can be written in a form which is local, involving integrals only over regions proximate to the solute. The DFT end point route to estimating solvation free energies provides an alternative path to that of IST for analyzing solvation effects on molecular recognition and conformational changes in solution, which can lead to new insights. In order to illustrate the kind of information that is contained in the solute-solvent PMF, we have carried out simulations of β-cyclodextrin in water. This solute is a well studied "host" molecule to which "guest" molecules bind; host-guest systems serve as models for molecular recognition. We illustrate the range of values the direct and indirect parts of the solute-solvent PMF can have as a water molecule is brought to the interface of β-cyclodextrin from the bulk; we discuss the "competition" between these two terms, and the role it plays in molecular recognition.

  4. PhySIC_IST: cleaning source trees to infer more informative supertrees.

    PubMed

    Scornavacca, Celine; Berry, Vincent; Lefort, Vincent; Douzery, Emmanuel J P; Ranwez, Vincent

    2008-10-04

    Supertree methods combine phylogenies with overlapping sets of taxa into a larger one. Topological conflicts frequently arise among source trees for methodological or biological reasons, such as long branch attraction, lateral gene transfers, gene duplication/loss or deep gene coalescence. When topological conflicts occur among source trees, liberal methods infer supertrees containing the most frequent alternative, while veto methods infer supertrees not contradicting any source tree, i.e. discard all conflicting resolutions. When the source trees host a significant number of topological conflicts or have a small taxon overlap, supertree methods of both kinds can propose poorly resolved, hence uninformative, supertrees. To overcome this problem, we propose to infer non-plenary supertrees, i.e. supertrees that do not necessarily contain all the taxa present in the source trees, discarding those whose position greatly differs among source trees or for which insufficient information is provided. We detail a variant of the PhySIC veto method called PhySIC_IST that can infer non-plenary supertrees. PhySIC_IST aims at inferring supertrees that satisfy the same appealing theoretical properties as with PhySIC, while being as informative as possible under this constraint. The informativeness of a supertree is estimated using a variation of the CIC (Cladistic Information Content) criterion, that takes into account both the presence of multifurcations and the absence of some taxa. Additionally, we propose a statistical preprocessing step called STC (Source Trees Correction) to correct the source trees prior to the supertree inference. STC is a liberal step that removes the parts of each source tree that significantly conflict with other source trees. Combining STC with a veto method allows an explicit trade-off between veto and liberal approaches, tuned by a single parameter.Performing large-scale simulations, we observe that STC+PhySIC_IST infers much more informative supertrees than PhySIC, while preserving low type I error compared to the well-known MRP method. Two biological case studies on animals confirm that the STC preprocess successfully detects anomalies in the source trees while STC+PhySIC_IST provides well-resolved supertrees agreeing with current knowledge in systematics. The paper introduces and tests two new methodologies, PhySIC_IST and STC, that demonstrate the interest in inferring non-plenary supertrees as well as preprocessing the source trees. An implementation of the methods is available at: http://www.atgc-montpellier.fr/physic_ist/.

  5. Sculpting the UMLS Refined Semantic Network.

    The Refined Semantic Network (RSN) for the UMLS was previously introduced to complement the UMLS Semantic Network (SN). The RSN partitions the UMLS Metathesaurus (META) into disjoint groups of concepts. Each such group is semantically uniform. However, the RSN was initially an order of magnitude larger than the SN, which is undesirable since to be useful, a semantic network should be compact. Most semantic types in the RSN represent combinations of semantic types in the UMLS SN. Such a "combination semantic type" is called Intersection Semantic Type (IST). Many ISTs are assigned to very few concepts. Moreover, when reviewing those concepts, many semantic type assignment inconsistencies were found. After correcting those inconsistencies many ISTs, among them some that contradicted UMLS rules, disappeared, which made the RSN smaller. The authors performed a longitudinal study with the goal of reducing the size of the RSN to become compact. This goal was achieved by correcting inconsistencies and errors in the IST assignments in the UMLS, which additionally helped identify and correct ambiguities, inconsistencies, and errors in source terminologies widely used in the realm of public health. In this paper, we discuss the process and steps employed in this longitudinal study and the intermediate results for different stages. The sculpting process includes removing redundant semantic type assignments, expanding semantic type assignments, and removing illegitimate ISTs by auditing ISTs of small extents. However, the emphasis of this paper is not on the auditing methodologies employed during the process, since they were introduced in earlier publications, but on the strategy of employing them in order to transform the RSN into a compact network. For this paper we also performed a comprehensive audit of 168 "small ISTs" in the 2013AA version of the UMLS to finalize the longitudinal study. Over the years it was found that the editors of the UMLS introduced some new inconsistencies that resulted in the reintroduction of unwarranted ISTs that had already been eliminated as a result of their previous corrections. Because of that, the transformation of the RSN into a compact network covering all necessary categories for the UMLS was slowed down. The corrections suggested by an audit of the 2013AA version of the UMLS achieve a compact RSN of equal magnitude as the UMLS SN. The number of ISTs has been reduced to 336. We also demonstrate how auditing the semantic type assignments of UMLS concepts can expose other modeling errors in the UMLS source terminologies, e.g., SNOMED CT, LOINC, and RxNORM that are important for health informatics. Such errors would otherwise stay hidden. It is hoped that the UMLS curators will implement all required corrections and use the RSN along with the SN when maintaining and extending the UMLS. When used correctly, the RSN will support the prevention of the accidental introduction of inconsistent semantic type assignments into the UMLS. Furthermore, this way the RSN will support the exposure of other hidden errors and inconsistencies in health informatics terminologies, which are sources of the UMLS. Notably, the development of the RSN materializes the deeper, more refined Semantic Network for the UMLS that its designers envisioned originally but had not implemented.

    A new multilayer IST-albedo Moderate Resolution Imaging Spectroradiometer (MODIS) product of Greenland was developed to meet the needs of the ice sheet modeling community. The multiple layers of the product enable the relationship between IST and albedo to be evaluated easily. Surface temperature is a fundamental input for dynamical ice sheet models because it is a component of the ice sheet radiation budget and mass balance. Albedo influences absorption of incoming solar radiation. The daily product will combine the existing standard MODIS Collection-6 ice-surface temperature, derived melt maps, snow albedo and water vapor products. The new product is available in a polar stereographic projection in NetCDF format. The product will ultimately extend from March 2000 through the end of 2017.

  14. Power games: The political use of solar technology in northern Thailand

    NASA Astrophysics Data System (ADS)

    Green, Donna Lisa

    This dissertation politicises and historically situates the transfer of an environmental technology to a less developed country, a transfer that has occurred under the rubric of sustainable development. The case study explores the social and political context of two solar battery charging station programmes selected to provide electrification in rural Northern Thailand beginning in the 1980s. It places these rural electrification programmes in the context of previous rural electrification policies in northern Thailand in the 1960s and 1970s which were driven by an explicitly state-serving agenda: an agenda that aimed to expand the centralised state's ability to pacify and control remote areas of the country. However, it is clear that the technology and implementation strategies selected for the new electrification programmes could not fulfil their community-serving objectives; furthermore, these systems could not meet the actual energy needs of the programmes' intended beneficiaries. I argue that we need to consider whether the objectives that motivated previous rural electrification programmes may be continuing to play a role in the promotion of these new rural electrification programmes, a motivation that would contradict the philosophy behind the choice of the solar battery charging stations. Specifically, I show how the new rural electrification strategy has been de-politicised through its framing within the sustainable development discourses. This thesis highlights how the rush to promote environmental technologies through the rubric of sustainable development may limit a proper consideration of the social and political dynamics that motivated these decisions, resulting in the uncritical justification of technology selection. Scholars have critiqued the social ramifications of, and the political motivations behind, earlier technocentric rural development strategies, showing how they can exacerbate social inequalities. I argue that in this situation, the alleged environmental benefits of using an environmental technology in a sustainable development programme may have served to shelter it from similar critique. The assessment reveals and emphasises the need to query the validity of the objectives motivating other technocentric rural development programmes that transfer environmental technologies as part of the practice of sustainable development.

    2016-01-01

    This study explores decision makers' perspectives on evidence-based policy (EBP) development using the case of TB/HIV co-infection in India. Twelve in-depth interviews were conducted with purposively selected key national and international policy decision makers in India. Verbatim transcripts were processed and analysed thematically using QSR (NUD*IST 6). The decision makers were unequivocal in recognizing the TB/HIV co-infection as an important public health issue in India and stated the problem to be different than Africa. The need of having a "third programme" for co-infection was not felt. According to them, the public health management of this co-infection must be within the realm of these two programmes. The study also emphasized on decision makers' perspectives on evidence and the process of utilization of evidence for decision-making for co-infection. Study findings showed global evidence was not always accepted by the decision makers and study shows several examples of decision makers demanding local evidence for policy decisions. Decision makers did make interim policies based on global evidence but most of the time their mandate was to get local evidence. Thus, operations research/implementation science especially multi-centric studies emerge as important strategy for EBP development. Researcher-policy maker interface was a gap where role of researcher as aggressive communicator of research findings was expected.

    This study assessed (a) the impact of a technology-aided programme on the leisure and communication engagement of persons with advanced amyotrophic lateral sclerosis (ALS) and (b) the opinion of rehabilitation and care personnel regarding the programme. The programme's impact was assessed with four participants who were allowed to activate leisure and communication options through basic responses (e.g. knee, finger or lip movements) and microswitches. Forty-two care and health professionals rated the programme after watching video clips of persons with ALS (three of the four involved in this study and three involved in previous studies) during and outside of the programme. The programme was effective with all participants. Their mean percentages of session time with independently initiated leisure and communication engagements were zero during baseline and increased to between nearly 70 and 80 during the intervention. The care and health professionals rated the technology-aided programme as beneficial for the participants' positive engagement and social image, fairly practical for daily contexts and interesting from a personal standpoint. The programme might be viewed as a viable resource for persons with advanced ALS. Implications for Rehabilitation A programme characterised by versatility, simplicity and relatively low cost could be considered practically relevant for persons with ALS and their contexts. A programme that is effective in fostering participants' independent leisure and communication engagement and is positively rated by care and rehabilitation personnel is more likely to be accepted and used with consistency. Any programme directed at persons affected by ALS needs to be adapted to the persons' progressive deterioration, starting from the response and microswitch used for accessing the programme's options.

    2017-08-01

    Decisions made by the National Institute for Health and Care Excellence (NICE) exert an influence on the allocation of resources within 'fixed' National Health Service budgets. Yet guidance for different types of health interventions is handled via different 'programmes' within NICE, which follow different methods and processes. The objective of this research was to identify differences in the processes and methods of NICE health technology assessment programmes and to explore how these could impact on allocative efficiency within the National Health Service. Data were extracted from the NICE technology appraisal programme, medical technologies guidance, diagnostic assessment programme, highly specialised technologies programme, and clinical guidelines process and methods manuals to undertake a systematic comparison. Five qualitative interviews were carried out with NICE members of staff and committee members to explore the reasons for the differences found. The main differences identified were in the required evidence review period, or lack thereof, mandatory funding status, the provision of a reference case for economic evaluation, the requirement for and the type of economic analysis undertaken, and the decision making criteria used for appraisal. Many of the differences found can be justified on grounds of practicality and relevance to the health technologies under assessment. Nevertheless, from a strict utilitarian view, there are several potential areas of inefficiency that could lead to the misallocation of resources within the National Health Service, although some of these might be eliminated or reduced if an egalitarian view is taken. The challenge is determining where society is willing to trade health gains between different people.

    Inserting a guide wire is a common practice during endo-urological procedures. A rare complication in patients with ureteral stones where an iatrogenic submucosal tunnel (IST) is created during endoscopic guide wire placement. Summarize data on IST. Retrospective descriptive study of patients treated from from October 2009 until January 2015. King Fahd Hospital of the University, Al-Khobar, Saudi Arabia. Patients with ureteral stones were divided to 2 groups. In group I (335 patients), the ureteral stones were removed by ureteroscopy in one stage. Group II (97 patients) had a 2-staged procedure starting with a double J-stent placement for kidney drainage followed within 3 weeks with ureteroscopic stone removal. Endoscopic visualization of ureteric submucosal tunneling by guide wire. IST occurred in 9/432 patients with ureteral stones (2.1%). The diagnosis in group I was made during ureteroscopy by direct visualization of a vanishing guide wire at the level of the stone (6 patients). In group II, IST was suspected when renal pain was not relieved after placement of the double J-stent or if imaging by ultrasound or intravenous urography showed persistent back pressure to the obstructed kidney (3 patients). The condition was subsequently confirmed by ureteroscopy. Forceful advancement of the guide wire in an inflamed and edematous ureteral segment impacted by a stone is probably the triggering factor for development of IST. Definitive diagnosis is possible only by direct visualization during ureteroscopy. Awareness of this potential complication is important to guard against its occurrence. Relatively small numbers of subjects and the retrospective nature of the study.

    2017-09-01

    Die Analyse nichtlinearer dynamischer Schaltungen ist bis heute eine herausfordernde Aufgabe, da nur selten analytische Lösungen angegeben werden können. Daher wurden eine Vielzahl von Methoden entwickelt, um eine qualitative oder quantitative Näherung für die Lösungen der Netzwerkgleichung zu erhalten. Oftmals wird beispielsweise eine Kleinsignalanalyse mit Hilfe einer Taylorreihe in einem Arbeitspunkt durchgeführt, die nach den Gliedern erster Ordnung abgebrochen wird. Allerdings ist diese Linearisierung nur in der Nähe des stabilen Arbeitspunktes für hyperbolische Systeme gültig. Besonders für die Analyse des dynamischen Verhaltens von Oszillatoren treten jedoch nicht-hyperbolische Systeme auf, sodass diese Methode nicht angewendet werden kann Mathis (2000). Carleman hat gezeigt, dass nichtlineare Differentialgleichungen mit polynomiellen Nichtlinearitäten in ein unendliches System von linearen Differentialgleichungen transformiert werden können Carleman (1932). Wird das unendlichdimensionale Gleichungssystem für numerische Zwecke abgebrochen, kann bei Oszillatoren der Übergang in eine stationäre Schwingung (Grenzzyklus) nicht wiedergegeben werden. In diesem Beitrag wird eine selbstkonsistente Carleman Linearisierung zur Untersuchung von Oszillatoren vorgestellt, die auch dann anwendbar ist, wenn die Nichtlinearitäten keinen Polynomen entsprechen. Anstelle einer linearen Näherung um einen Arbeitspunkt, erfolgt mit Hilfe der Carleman Linearisierung eine Approximation auf einem vorgegebenen Gebiet. Da es jedoch mit der selbstkonsistenten Technik nicht möglich ist, das stationäre Verhalten von Oszillatoren zu beschreiben, wird die Berechnung einer Poincaré-Abbildung durchgeführt. Mit dieser ist eine anschließende Analyse des Oszillators möglich.

    Enhanced melting of the Greenland Ice Sheet has been documented in recent literature along with surface-temperature increases measured using infrared satellite data since 1981. Using a recently-developed climate-quality data record, 11- and 12-year trends in the clear-sky ice-surface temperature (IST) of the Greenland Ice Sheet have been studied using the Moderate-Resolution Imaging Spectroradiometer (MODIS) IST product. Daily and monthly MODIS ISTs of the Greenland Ice Sheet beginning on 1 March 2000 and continuing through 31 December 2010 are now available at 6.25-km spatial resolution on a polar stereographic grid as described in Hall et al. (submitted). This record will be elevated in status to a climate-data record (CDR) when more years of data become available either from the MODIS on the Terra or Aqua satellites, or from the Visible Infrared Imager Radiometer Suite (VIIRS) to be launched in October 2011. Maps showing the maximum extent of melt for the entire ice sheet and for the six major drainage basins have been developed from the MODIS IST dataset. Twelve-year trends of the duration of the melt season on the ice sheet vary in different drainage basins with some basins melting progressively earlier over the course of the study period. Some (but not all) of the basins also show a progressively-longer duration of melt. IST 12-year trends are compared with in-situ data, and climate data from the Modern Era Retrospective-Analysis for Research and Applications (MERRA) Reanalysis.

    Fischer, Joachim

    Zunächst kurz vorweg zu den Formeln im Titel: "exzentrische Positionalität“ ist der Kategorienvorschlag der Philosophischen Anthropologie (genauer: von Helmuth Plessner) für den Menschen, für seine "Sonderstellung“ unter den Lebewesen - ich werde diesen Begriff erläutern. So viel kann man sagen: Der Terminus ist nicht schwieriger als "Transzendentalität“ oder das "Apriori“ oder "Autopoiesis“, also Begriffe, mit deren Orientierungswert in der intellektuellen Öffentlichkeit bereits gespielt wird, bietet aber möglicherweise mehr Erschließungskraft als die Kunstbegriffe z. B. von Kant, Maturana oder Luhmann. Und "tanzendes Tier“ ist ein glücklicher Anschauungsbegriff, eine Art Übersetzung für "exzentrische Positionalität“ - also ein "verrücktes“ Lebewesen, eine Verrückung im evolutionären Leben, die dieses Lebewesen von Natur aus zu einer bestimmten Art von Lebensführung, nämlich Kultur nötigt. Die Absicht des Beitrages ist es, die Philosophische Anthropologie als eine spezifische Theorietechnik zu präsentieren, um einen adäquaten Begriff des Menschen zu erreichen, und zwar eine Theoriestrategie angesichts des cartesianischen Dualismus - also des Dualismus zwischen Naturalismus und Kulturalismus.

    The increasing volume of data describing human disease processes and the growing complexity of understanding, managing, and sharing such data presents a huge challenge for clinicians and medical researchers. This paper presents the @neurIST system, which provides an infrastructure for biomedical research while aiding clinical care, by bringing together heterogeneous data and complex processing and computing services. Although @neurIST targets the investigation and treatment of cerebral aneurysms, the system's architecture is generic enough that it could be adapted to the treatment of other diseases. Innovations in @neurIST include confining the patient data pertaining to aneurysms inside a single environment that offers clinicians the tools to analyze and interpret patient data and make use of knowledge-based guidance in planning their treatment. Medical researchers gain access to a critical mass of aneurysm related data due to the system's ability to federate distributed information sources. A semantically mediated grid infrastructure ensures that both clinicians and researchers are able to seamlessly access and work on data that is distributed across multiple sites in a secure way in addition to providing computing resources on demand for performing computationally intensive simulations for treatment planning and research.

  8. The role of small satellites in the development of the South African space programme

    NASA Astrophysics Data System (ADS)

    Martinez, Peter

    In the 1990s a team of scientists and engineers at Stellenbosch University built the first South African satellite to fly in space, the 64-kg Sunsat. This university-based satellite programme took advantage of the skills and facilities developed in the previous South African space programme of the 1980s and early 1990s, which had developed a much larger satellite (Greensat), but was cancelled in the mid-1990s prior to launch. Sunsat incorporated a number of novel capabilities for a microsatellite platform, and interest was shown in these technologies by other groups developing similar satellites. As the University was not the ideal environment to develop the commercial potential of these microsatellite technologies, a company called Sunspace was later established, thus creating industrial capacity in South Africa in a niche area of space technology. This new industrial capability, together with the infrastructure from the previous space programme, have created a foundation upon which to build the new South African space programme. This paper discusses the historical, current and possible future roles of small satellites in the development of the South African space programme.

    Für den Tourismus haben Klima und Wetter eine große Relevanz: als Treiber des Verhaltens wie auch als Angebotsfaktor. Wetter und Klima sind demnach sowohl Bestandteil des touristischen Angebotes als auch limitierende Faktoren des Tourismus und Steuergrößen für die touristische Nachfrage. Insofern liegt es nahe, dass dieser Sektor vom Klimawandel betroffen sein wird. Der Tourismus ist aber auch ein Faktor, der seinerseits erheblich auf das Klima und den Klimawandel zurückwirkt. Dabei ist der Klimawandel aber nur einer von vielen voneinander abhängig erscheinenden Einflussfaktoren, denen der Sektor "Tourismus" ausgesetzt ist. Das heißt, es handelt sich um ein komplexes Wirkungsgefüge. Das Kapitel widmet sich den Klimawandelfolgen im Tourismus und macht diese beispielhaft an den Regionen "Küsten" sowie "Mittel- und Hochgebirge" fest, um Anpassungsmöglichkeiten anzufügen.

    We have investigated the stability of the MODerate resolution Imaging Spectroradiometer (MODIS) infrared-derived ice surface temperature (IST) data from Terra for use as a climate quality data record. The availability of climate quality air temperature data (TA) from a NOAA Global Monitoring Division observatory at Greenlands Summit station has enabled this high temporal resolution study of MODIS ISTs. During a 5 year period (July 2008 to August 2013), more than 2500 IST values were compared with 3-minute average TA values derived from the 1-minute data from NOAAs primary 2 m air temperature sensor. These data enabled an expected small offset between air and surface temperatures at this the ice sheet location to be investigated over multiple annual cycles.

    The aim of this paper is to explore the profile of dental nursing students in the National Dental Nurse Training Programme of Ireland and their adjustment to a technology-assisted learning environment. Evaluation by students of the course and their reactions to the course were analysed. Dental nurses must possess the skills and knowledge to proficiently function in the modern day dental surgery. The implementation of a dental nurse programme that is heavily reliant on technology has started to create a group of dental nurses equipped with basic skills to access and retrieve information over a lifetime. However, the transition to a technology-assisted learning environment including online learning activities requires adaptation and expertise by educators and students alike. Careful evaluation and stakeholder feedback is imperative in the creation and maintaining of a quality programme. In conclusion, the students in this study responded well to the transition to a technology-based learning environment. Furthermore, the findings of this study suggest that the use of an online environment is an effective and stimulating learning environment for the students of a dental nurse programme; however, familiarity skills and knowledge of information technology is a prerequisite for success.

    The National Institute for Health Research (NIHR) Invention for Innovation (i4i) programme supports the development of innovative medical technologies for patient benefit. The i4i product development stream involves collaborative projects between at least two partners from academia, the NHS and industry. Medical technology innovators apply for funding for one to three years, through a peer review-based process that includes presentation to a selection panel. The funding and business advice provided by i4i support the development of early-stage innovations, generally at proof of concept and prototype stages. Since its inception the product development stream has identified and supported 170 projects, led by 146 principal investigators (PIs). RAND Europe evaluated the programme, with the aim of identifying its outputs and impacts and examining the factors influencing performance. The evaluation findings should help inform the future of the programme. The evaluation used a multi-method approach, including a focused review of background information from i4i, scoping interviews with key informants, a survey of programme participants and case studies of projects representing diverse technologies and health needs.

  19. In Vivo and In Situ Detection of Macromolecular Free Radicals Using Immuno-Spin Trapping and Molecular Magnetic Resonance Imaging.

    PubMed

    Towner, Rheal A; Smith, Nataliya

    2018-05-20

    In vivo free radical imaging in preclinical models of disease has become a reality. Free radicals have traditionally been characterized by electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy coupled with spin trapping. The disadvantage of the ESR/EPR approach is that spin adducts are short-lived due to biological reductive and/or oxidative processes. Immuno-spin trapping (IST) involves the use of an antibody that recognizes macromolecular 5,5-dimethyl-pyrroline-N-oxide (DMPO) spin adducts (anti-DMPO antibody), regardless of the oxidative/reductive state of trapped radical adducts. Recent Advances: The IST approach has been extended to an in vivo application that combines IST with molecular magnetic resonance imaging (mMRI). This combined IST-mMRI approach involves the use of a spin-trapping agent, DMPO, to trap free radicals in disease models, and administration of an mMRI probe, an anti-DMPO probe, which combines an antibody against DMPO-radical adducts and an MRI contrast agent, resulting in targeted free radical adduct detection. The combined IST-mMRI approach has been used in several rodent disease models, including diabetes, amyotrophic lateral sclerosis (ALS), gliomas, and septic encephalopathy. The advantage of this approach is that heterogeneous levels of trapped free radicals can be detected directly in vivo and in situ to pin point where free radicals are formed in different tissues. The approach can also be used to assess therapeutic agents that are either free radical scavengers or generate free radicals. Smaller probe constructs and radical identification approaches are being considered. The focus of this review is on the different applications that have been studied, advantages and limitations, and future directions. Antioxid. Redox Signal. 28, 1404-1415.

    In acute ischemic stroke, the hyperdense artery sign (HAS) on noncontrast computed tomography (CT) is thought to represent intraluminal thrombus and, therefore, is a surrogate of arterial obstruction. We sought to assess the accuracy of HAS as a marker of arterial obstruction by thrombus. The Third International Stroke Trial (IST-3) was a randomized controlled trial testing the use of intravenous thrombolysis for acute ischemic stroke in patients who did not clearly meet the prevailing license criteria. Some participating IST-3 centers routinely performed CT or MR angiography at baseline. One reader assessed all relevant scans independently, blinded to all other data; we checked observer reliability. We combined IST-3 data with a systematic review and meta-analysis of all studies that assessed the accuracy of HAS using angiography (any modality). IST-3 had 273 patients with baseline CT or MR angiography and was the largest study of HAS accuracy. The meta-analysis (n=902+273=1175, including IST-3) found sensitivity and specificity of HAS for arterial obstruction on angiography to be 52% and 95%, respectively. HAS was more commonly identified in proximal than distal arteries (47% versus 37%; P=0.015), and its sensitivity increased with thinner CT slices (r=-0.73; P=0.001). Neither extent of obstruction nor time after stroke influenced HAS accuracy. When present in acute ischemic stroke, HAS indicates a high likelihood of arterial obstruction, but its absence indicates only a 50/50 chance of normal arterial patency. Thin-slice CT improves sensitivity of HAS detection. http://www.controlled-trials.com/ISRCTN25765518. Unique identifier: ISRCTN25765518. © 2014 American Heart Association, Inc.

  1. Post-therapeutic recovery of serum interleukin-35 level might predict positive response to immunosuppressive therapy in pediatric aplastic anemia.

    The predictive value of interleukin-35 (IL-35) on efficacy of immunosuppressive therapy (IST) in aplastic anemia (AA) has not been well investigated. The aim of the study was to evaluate the association between serum IL-35 level and response to IST in pediatric AA. A total of 154 children with AA and 154 controls were included between January 2012 and December 2013. Blood and bone marrow fluid specimens were collected. Serum level of IL-35 was determined by enzyme-linked immunosorbent assay. Patients were treated with IST, and response to therapy was evaluated during 180-day follow-up period after starting therapy. Serum levels of IL-35 at admission decreased significantly in patients compared with that in controls (10.9 ± 5.5 pg ml -1 and 45.3 ± 8.8 pg ml -1 , p < 0.001). After starting IST, serum levels of IL-35 in patients recovered 30.7 ± 9.7 pg ml -1 in the first 28 days (p < 0.001). During the follow-up period, increased range of serum IL-35 level ≥30.7 pg ml -1 in the first 28 days was associated with effective response to therapy (odds ratio 7.97, 95% confidence interval 3.82-16.79). In addition, Fas/FasL protein expression in bone marrow mononuclear cells dropped significantly in the same group of patients in the first 28 days (p < 0.05). The study revealed that post-therapeutic recovery of circulating IL-35 concentration might be an independent predictor for effective response to IST in pediatric AA. Moreover, apoptosis might be involved in such a forecasting process.

    This study tested a bone-tendon allograft versus human dermis patch for reconstructing chronic rotator cuff repair by use of a canine model. Mature research dogs (N = 15) were used. Radiopaque wire was placed in the infraspinatus tendon (IST) before its transection. Three weeks later, radiographs showed IST retraction. Each dog then underwent 1 IST treatment: debridement (D), direct repair of IST to bone with a suture bridge and human dermis patch augmentation (GJ), or bone-tendon allograft (BT) reconstruction. Outcome measures included lameness grading, radiographs, and ultrasonographic assessment. Dogs were killed 6 months after surgery and both shoulders assessed biomechanically and histologically. BT dogs were significantly (P = .01) less lame than the other groups. BT dogs had superior bone-tendon, tendon, and tendon-muscle integrity compared with D and GJ dogs. Biomechanical testing showed that the D group had significantly (P = .05) more elongation than the other groups whereas BT had stiffness and elongation characteristics that most closely matched normal controls. Radiographically, D and GJ dogs showed significantly more retraction than BT dogs (P = .003 and P = .045, respectively) Histologically, GJ dogs had lymphoplasmacytic infiltrates, tendon degeneration and hypocellularity, and poor tendon-bone integration. BT dogs showed complete incorporation of allograft bone into host bone, normal bone-tendon junctions, and well-integrated allograft tendon. The bone-tendon allograft technique re-establishes a functional IST bone-tendon-muscle unit and maintains integrity of repair in this model. Clinical trials using this bone-tendon allograft technique are warranted. Copyright © 2012 Arthroscopy Association of North America. Published by Elsevier Inc. All rights reserved.

    2014-01-01

    The treatment of aplastic anemia is currently with immunosuppressive therapy (IST) with antithymocyte globulin and cyclosporine, to which two thirds of patients respond. However, a significant proportion of these responders relapse and many have persistent cytopenias. The management of these patients is challenging. Modifications to this standard approach using alternative immunosuppressive agents or adding hematopoietic cytokines such as G-CSF and erythropoietin have not improved outcome. A recent trial has shown that eltrombopag, a thrombopoeitin mimetic, is efficacious in the treatment of patients with severe aplastic anemia (SAA) refractory to IST. There is evidence that this drug works by directly stimulating marrow stem and progenitor cells thereby promoting hematopoietic recovery in patients with bone marrow failure. Several trials are ongoing in our institution using this very promising drug in combination therapy in the upfront treatment of SAA, in IST refractory SAA and in moderate disease. PMID:25578417

    Immunosuppressive therapy (IST) with antithymocyte globulin (ATG) and cyclosporine (CsA) is the standard treatment for children with severe aplastic anemia (SAA) with no human leukocyte antigen-matched siblings. Due to the unavailability of horse ATG in China, porcine antilymphocyte globulin (p-ALG), which is less expensive and more effective than rabbit ATG, is widely used. We sought to evaluate the efficacy and safety profile of modified IST with p-ALG plus delayed CsA at day 21 in 50 SAA children. Eighteen SAA patients who progressed from nonsevere aplastic anemia (NSAA) were classified as SAA-II; the other 32 patients were classified as SAA-I. Overall response (OR) rates at 3, 6 and 12 months were 56, 64 and 62%, respectively. The 10-year overall survival (OS) rate and disease-free survival (DFS) rate were 80 and 56%. The OR, OS and DFS rates in the SAA-I group were clearly better than those in the SAA-II group. Death rate from infection within 30 days was 4%. Modified IST with p-ALG plus delayed CsA is a reliable and well-tolerated treatment for children with SAA, and reduces early death due to infection. Modified IST is more suitable for children with SAA-I.

    The influence of chronic hepatitis B virus (HBV) infection on the efficacy of intensive immunosuppressive treatment (IST) of severe aplastic anaemia (SAA) patients remains unclear. Previous reports on this topic have been mostly case reports or have had a relatively short follow-up. Eight SAA patients carrying chronic HBV infection and 24 matched patients without HBV at a ratio of 1:3 were included in this retrospective analysis. The patients were treated with anti-thymocyte globulin (ATG) and cyclosporine A. Entecavir was or was not administered throughout the IST course to patients with positive or negative HBV-DNA results, respectively. No evident HBV reactivation developed. The overall response was 87.5% by 12 months, and the recurrence rate was 12.5%. There were no significant differences in overall response, overall survival and event-free survival between groups. Entecavir can effectively prevent reactivation of HBV in SAA patients with positive HBV-DNA who received intensive IST. Regular surveillance may be sufficient for HBV-DNA negative patients who should receive antiviral drugs immediately when their HBV-DNA status changes from negative to positive. The prognosis of SAA patients with chronic HBV infection after intensive IST treatment is not worse than those without HBV infection.

  9. Hematopoietic stem cell transplantation for acquired aplastic anemia

    2016-01-01

    Purpose of review There has been steady improvement in outcomes with allogeneic bone marrow transplantation (BMT) for severe aplastic anemia (SAA), due to progress in optimization of the conditioning regimens, donor hematopoietic cell source and supportive care. Here we review recently published data that highlight the improvements and current issues in the treatment of SAA. Recent findings Approximately one-third of AA patients treated with immune suppression therapy (IST) have acquired mutations in myeloid cancer candidate genes. Because of the greater probability for eventual failure of IST, human leukocyte antigen (HLA)-matched sibling donor BMT is the first-line of treatment for SAA. HLA-matched unrelated donor (URD) BMT is generally recommended for patients who have failed IST. However, in younger patients for whom a 10/10-HLA-allele matched URD can be rapidly identified, there is a strong rationale to proceed with URD BMT as first-line therapy. HLA-haploidentical BMT using post-transplant cyclophosphamide (PT-CY) conditioning regimens, is now a reasonable second-line treatment for patients who failed IST. Summary Improved outcomes have led to an increased first-line role of BMT for treatment of SAA. The optimal cell source from an HLA-matched donor is bone marrow. Additional studies are needed to determine the optimal conditioning regimen for HLA-haploidentical donors. PMID:27607445

    Das Werner-Syndrom ist eine segmental progeroide Erkrankung mit Beginn in der Adoleszenz oder im frühen Erwachsenenalter. Typische Symptome, die zum vorgealterten Phänotyp beitragen, sind ein post-pubertär auftretender Kleinwuchs, Katarakte, eine vorzeitige Ergrauung/Ausdünnung des Haupthaars, sklerodermieähnliche Hautveränderungen und eine regionale Atrophie des subkutanen Fettgewebes. Darüber hinaus kommt es früh und gehäuft zu „Alterserkrankungen“ wie z. B. einem Diabetes mellitus Typ 2, einer Osteoporose, einer Atherosklerose sowie verschiedenen malignen Tumoren. Das Werner-Syndrom wird autosomal- rezessiv vererbt und ist durch Mutationen im Werner-Gen (WRN) bedingt. Es wurden bis heute mehr als 70 über das gesamte Gen verteilte Mutationen identifiziert, die typischerweise zu einem Verlust der Genfunktion führen. WRN kodiert für eine RecQ-Typ- Helikase, die u. a. an der DNA-Reparatur und der Aufrechterhaltung der DNA-Integrität beteiligt ist, was sich in einer erhöhten genetischen Instabilität in Patientenzellen wider-spiegelt. Trotz der relativen Seltenheit ist die Analyse des Werner-Syndroms von allgemeiner Bedeutung, um die Rolle der DNA-Stabilität und Integrität für das Altern sowie die Entwicklung altersassoziierter Erkrankungen besser zu verstehen.

    Limited human studies have directly tested the dissociation between wanting and liking with human substance users, a core tenet of the Incentive Sensitisation Theory (IST). The aim of this study is to test the dissociation between wanting and liking in humans across two commonly used licit substances, alcohol and caffeine. The STRAP-R (Sensitivity To Reinforcement of Addictive and other Primary Rewards) questionnaire was administered to 285 alcohol users (mean age=33.30, SD= 8.83) and 134 coffee users (mean age=33.05, SD=8.10) ranging in their levels of substance use to assess wanting and liking. Findings showed that in high risk alcohol users wanting may drive alcohol consumption more so than liking, compared with low risk alcohol users. However, wanting and liking did not significantly dissociate as alcohol consumption increased. These findings partially support IST. Additionally, IST was not supported in coffee users. It is possible that caffeine functions differently at the neurological level compared with alcohol, perhaps explaining the lack of dissociation emerging in coffee users as caffeine use increased. Nevertheless, the current study makes several contributions to IST research. Future studies should focus on utilising the STRAP-R with a clinically dependent sample to test the dissociation between wanting and liking.

    State of the an programmable devices are utilizing advanced processing technologies, non-standard circuit structures, and unique electrical elements in commercial-off-the-shelf (COTS)-based, high-performance devices. This paper will discuss that the above factors, coupled with the systems application environment, have a strong interplay that affect the radiation hardness of programmable devices and have resultant system impacts in (1) reliability of the unprogrammed, biased antifuse for heavy ions (rupture), (2) logic upset manifesting itself as clock upset, and (3) configuration upset. General radiation characteristics of advanced technologies are examined and manufacturers' modifications to their COTS-based and their impact on future programmable devices will be analyzed.

  13. Geothermal projects funded under the NER 300 programme - current state of development and knowledge gained

    2017-04-01

    Introduction The NER 300 programme, managed by the European Commission is one of the largest funding programmes for innovative low-carbon energy demonstration projects. NER 300 is so called because it is funded from the sale of 300 million emission allowances from the new entrants' reserve (NER) set up for the third phase of the EU emissions trading system (ETS). The programme aims to successfully demonstrate environmentally safe carbon capture and storage (CCS) and innovative renewable energy (RES) technologies on a commercial scale with a view to scaling up production of low-carbon technologies in the EU. Consequently, it supports a wide range of CCS and RES technologies (bioenergy, concentrated solar power, photovoltaics, geothermal, wind, ocean, hydropower, and smart grids). Funded projects and the role of geothermal projects for the programme In total, about EUR 2.1 billion have been awarded through the programme's 2 calls for proposals (the first awarded in December 2012, the second in July 2014). The programme has awarded around EUR 70 million funding to 3 geothermal projects in Hungary, Croatia and France. The Croatian geothermal project will enter into operation during 2017 the Hungarian in 2018, and the French in 2020. Knowledge Sharing Knowledge sharing requirements are built into the legal basis of the programme as a critical tool to lower risks in bridging the transition to large-scale production of innovative renewable energy and CCS deployment. Projects have to submit annually to the European Commission relevant knowledge gained during that year in the implementation of their project. The relevant knowledge is aggregated and disseminated by the European Commission to industry, research, government, NGO and other interest groups and associations in order to provide a better understanding of the practical challenges that arise in the important step of scaling up technologies and operating them at commercial scale. The knowledge sharing of the NER 300 programme should lead to better planning and faster introduction of low carbon technologies in the future. Content of the presentation The presentation will introduce the geothermal projects that have been awarded funding (see Annex), including their state-of-play. Insights and knowledge gained from the projects that have entered into operation will be shown and discussed. Furthermore, the presentation will provide an overview of the NER 300 programme.

    In the context of an IST European project with acronym PANACEIA-ITV, a home care service provisioning system is described, based on interactive TV technology. The purpose of PANACEIA-ITV is to facilitate essential lifestyle changes and to promote compliance with scientifically sound self-care recommendations, through the application of interactive digital television for family health maintenance. The means to achieve these goals are based on technological, health services and business models. PANACEIA-ITV is looking for communication of monitoring micro-devices with I-TV set-top-boxes using infrared technology, and embodiment of analogous H/W and S/W in the I-TV set-top-boxes. Intelligent agents are used to regulate data flow, user queries as well as service provisions from and to the household through the satellite digital platform, the portal and the back-end decision support mechanisms, using predominantly the Active Service Provision (ASP) model. Moreover, interactive digital TV services are developed for the delivery of health care in the home care environment.

    Teamwork and communication often play a role in adverse clinical events. Due to the multidisciplinary and time-sensitive nature of trauma care, the effects of teamwork and communication can be especially pronounced in the treatment of the acutely injured patient. Our hypothesis was that an in situ trauma simulation (ISTS) program (simulating traumas in the trauma bay with all members of the trauma team) could be implemented in an emergency department (ED) and that this would improve teamwork and communication measured in the clinical setting. This was an observational study of the effect of an ISTS program on teamwork and communication during trauma care. The authors observed a convenience sample of 39 trauma activations. Cases were selected by their presenting to the resuscitation bay of a Level I trauma center between 09:00 and 16:00, Monday through Thursday, during the study period. Teamwork and communication were measured using the previously validated Clinical Teamwork Scale (CTS). The observers were three Trauma Nursing Core Course certified RNs trained on the CTS by observing simulated and actual trauma cases and following each of these cases with a discussion of appropriate CTS scores with two certified Advanced Trauma Life Support instructors/emergency physicians. Cases observed for measurement were scored in four phases: 1) preintervention phase (baseline); 2) didactic-only intervention, the phase following a lecture series on teamwork and communication in trauma care; 3) ISTS phase, real trauma cases scored during period when weekly ISTSs were performed; and 4) potential decay phase, observations following the discontinuation of the ISTSs. Multirater agreement was assessed with Krippendorf's alpha coefficient; agreement was excellent (mean agreement = 0.92). Nonparametric procedures (Kruskal-Wallis) were used to test the hypothesis that the scores observed during the various phases were different and to compare each individual phase to baseline scores. The ISTS program was implemented and achieved regular participation of all components of our trauma team. Data were collected on 39 cases. The scores for 11 of 14 measures improved from the baseline to the didactic phase, and the mean and median scores of all CTS component measures were greatest during the ISTS phase. When each phase was compared to baseline scores, using the baseline as a control, there were no significant differences seen during the didactic or the decay phases, but 12 of the 14 measures showed significant improvements from the baseline to the simulation phase. However, when the Kruskal-Wallis test was used to test for differences across all phases, only overall communication showed a significant difference. During the potential decay phase, the scores for every measure returned to baseline phase values. This study shows that an ISTS program can be implemented with participation from all members of a multidisciplinary trauma team in the ED of a Level I trauma center. While teamwork and communication in the clinical setting were improved during the ISTS program, this effect was not sustained after ISTS were stopped. © 2012 by the Society for Academic Emergency Medicine.

    The National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme supports research tailored to the needs of NHS decision-makers, patients and clinicians. This study reviewed the impact of the programme, from 2003 to 2013, on health, clinical practice, health policy, the economy and academia. It also considered how HTA could maintain and increase its impact. Interviews (n = 20): senior stakeholders from academia, policy-making organisations and the HTA programme. Bibliometric analysis: citation analysis of publications arising from HTA programme-funded research. Researchfish survey: electronic survey of all HTA grant holders. Payback case studies (n = 12): in-depth case studies of HTA programme-funded research. We make the following observations about the impact, and routes to impact, of the HTA programme: it has had an impact on patients, primarily through changes in guidelines, but also directly (e.g. changing clinical practice); it has had an impact on UK health policy, through providing high-quality scientific evidence - its close relationships with the National Institute for Health and Care Excellence (NICE) and the National Screening Committee (NSC) contributed to the observed impact on health policy, although in some instances other organisations may better facilitate impact; HTA research is used outside the UK by other HTA organisations and systematic reviewers - the programme has an impact on HTA practice internationally as a leader in HTA research methods and the funding of HTA research; the work of the programme is of high academic quality - the Health Technology Assessment journal ensures that the vast majority of HTA programme-funded research is published in full, while the HTA programme still encourages publication in other peer-reviewed journals; academics agree that the programme has played an important role in building and retaining HTA research capacity in the UK; the HTA programme has played a role in increasing the focus on effectiveness and cost-effectiveness in medicine - it has also contributed to increasingly positive attitudes towards HTA research both within the research community and the NHS; and the HTA focuses resources on research that is of value to patients and the UK NHS, which would not otherwise be funded (e.g. where there is no commercial incentive to undertake research). The programme should consider the following to maintain and increase its impact: providing targeted support for dissemination, focusing resources when important results are unlikely to be implemented by other stakeholders, particularly when findings challenge vested interests; maintaining close relationships with NICE and the NSC, but also considering other potential users of HTA research; maintaining flexibility and good relationships with researchers, giving particular consideration to the Technology Assessment Report (TAR) programme and the potential for learning between TAR centres; maintaining the academic quality of the work and the focus on NHS need; considering funding research on the short-term costs of the implementation of new health technologies; improving the monitoring and evaluation of whether or not patient and public involvement influences research; improve the transparency of the priority-setting process; and continuing to monitor the impact and value of the programme to inform its future scientific and administrative development.

  1. Wie wissenschaftlich ist der Evolutionsgedanke?

    NASA Astrophysics Data System (ADS)

    Vollmer, Gerhard

    Darwin war ein besonnener Mann; alles Aufsehen war ihm zuwider. Trotzdem hat er eine Revolution ausgelöst, deren Wirkung nicht auf die Biologie beschränkt blieb. Seine Theorie lässt sich in fünf Teiltheorien zerlegen, die sich durch die Begriffe Artenwandel, Verwandtschaft alles Lebendigen und gemeinsamer Ursprung, Artenaufspaltung und Artenvielfalt, Gradualismus, natürliche Auslese charakterisieren lassen. Dadurch wurden mehrere religiöse und weitere weltanschauliche Überzeugungen in Frage gestellt. Deshalb wird die Evolutionstheorie auch heute noch vielfach kritisiert, ja bekämpft. Die Vorwürfe lassen sich ordnen nach den Kriterien, mit denen wir erfahrungswissenschaftliche Theorien beurteilen. Haltbar ist daran nur, dass es für die Evolutionstheorie zwar beliebig viele Bestätigungen gibt, aber nur wenige Widerlegungsmöglichkeiten. Durch die neuerdings entwickelten und durchgeführten Evolutionsexperimente ist die empirische Situation allerdings deutlich besser geworden. Am (erfahrungs)wissenschaftlichen Charakter der Evolutionstheorie besteht deshalb kein Zweifel.

    Globalization and concurrent development in computer and communication technology has increased interest in collaborative online teaching and learning for students in higher education institutions. Many institutions and teachers have introduced computer-supported programmes in areas including dental hygiene. The potential for the use of this technology is exciting; however, its introduction should be careful and considered. We suggest that educators wanting to introduce computer-supported programmes make explicit their pedagogical principles and then select technologies that support and exploit these principles. This paper describes this process as it was applied to the development of an international web-based collaborative learning programme for dental hygiene students.

    Objective To assess the time to publication of primary research and evidence syntheses funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) Programme published as a monograph in Health Technology Assessment and as a journal article in the wider biomedical literature. Study design Retrospective cohort study. Setting Primary research and evidence synthesis projects funded by the HTA Programme were included in the cohort if they were registered in the NIHR research programmes database and was planned to submit the draft final report for publication in Health Technology Assessment on or before 9 December 2011. Main outcome measures The median time to publication and publication at 30 months in Health Technology Assessment and in an external journal were determined by searching the NIHR research programmes database and HTA Programme website. Results Of 458 included projects, 184 (40.2%) were primary research projects and 274 (59.8%) were evidence syntheses. A total of 155 primary research projects had a completion date; the median time to publication was 23 months (26.5 and 35.5 months to publish a monograph and to publish in an external journal, respectively) and 69% were published within 30 months. The median time to publication of HTA-funded trials (n=126) was 24 months and 67.5% were published within 30 months. Among the evidence syntheses with a protocol online date (n=223), the median time to publication was 25.5 months (28 months to publication as a monograph), but only 44.4% of evidence synthesis projects were published in an external journal. 65% of evidence synthesis studies had been published within 30.0 months. Conclusions Research funded by the HTA Programme publishes promptly. The importance of Health Technology Assessment was highlighted as the median time to publication was 9 months shorter for a monograph than an external journal article. PMID:24285634

  9. PhySIC_IST: cleaning source trees to infer more informative supertrees

    Scornavacca, Celine; Berry, Vincent; Lefort, Vincent; Douzery, Emmanuel JP; Ranwez, Vincent

    2008-01-01

    Background Supertree methods combine phylogenies with overlapping sets of taxa into a larger one. Topological conflicts frequently arise among source trees for methodological or biological reasons, such as long branch attraction, lateral gene transfers, gene duplication/loss or deep gene coalescence. When topological conflicts occur among source trees, liberal methods infer supertrees containing the most frequent alternative, while veto methods infer supertrees not contradicting any source tree, i.e. discard all conflicting resolutions. When the source trees host a significant number of topological conflicts or have a small taxon overlap, supertree methods of both kinds can propose poorly resolved, hence uninformative, supertrees. Results To overcome this problem, we propose to infer non-plenary supertrees, i.e. supertrees that do not necessarily contain all the taxa present in the source trees, discarding those whose position greatly differs among source trees or for which insufficient information is provided. We detail a variant of the PhySIC veto method called PhySIC_IST that can infer non-plenary supertrees. PhySIC_IST aims at inferring supertrees that satisfy the same appealing theoretical properties as with PhySIC, while being as informative as possible under this constraint. The informativeness of a supertree is estimated using a variation of the CIC (Cladistic Information Content) criterion, that takes into account both the presence of multifurcations and the absence of some taxa. Additionally, we propose a statistical preprocessing step called STC (Source Trees Correction) to correct the source trees prior to the supertree inference. STC is a liberal step that removes the parts of each source tree that significantly conflict with other source trees. Combining STC with a veto method allows an explicit trade-off between veto and liberal approaches, tuned by a single parameter. Performing large-scale simulations, we observe that STC+PhySIC_IST infers much more informative supertrees than PhySIC, while preserving low type I error compared to the well-known MRP method. Two biological case studies on animals confirm that the STC preprocess successfully detects anomalies in the source trees while STC+PhySIC_IST provides well-resolved supertrees agreeing with current knowledge in systematics. Conclusion The paper introduces and tests two new methodologies, PhySIC_IST and STC, that demonstrate the interest in inferring non-plenary supertrees as well as preprocessing the source trees. An implementation of the methods is available at: . PMID:18834542

    Schulz, Detlef

    Nur mit einer zuverlässigen und wirtschaftlichen elektrischen Energieversorgung ist eine nachhaltige gesellschaftliche Entwicklung von Industrienationen möglich. Gleichzeitig muss diese selbst so nachhaltig, d. h. umweltverträglich gestaltet werden, dass auch zukünftige Generationen nicht in ihrer Entfaltung behindert werden. Eine versorgungssichere, wirtschaftliche und umweltverträgliche Energiebereitstellung ergibt sich nicht zwingend allein aus einer technisch evolutionären Entwicklung und ist auch bis heute nicht ausschließlich nur mit einer der bekannten Wandlungstechnologien nachweislich realisierbar.

    This research was conducted to assess the Spanish-language Trauma Symptom Inventory's (Briere, 1995) suitability for use with a Puerto Rican sample. Minor revisions were made to the original instrument following a comprehensive appraisal involving a bilingual committee and pilot focus group. The present study outlines the review and adaptation process and examines the psychometric properties of the revised instrument, the Inventario de Síntomas de Trauma-Revisado (IST-R). A sample of 225 students (155 women, 70 men) at the University of Puerto Rico, age 20 to 59 (M = 23.24, SD = 4.69), participated in the validation study. Participants completed a demographic questionnaire; a self-report trauma exposure instrument; and measures of psychological distress, including Spanish-language versions of the Beck Depression Inventory, Symptom Checklist-36, and the Dissociative Experiences Scale. Reliability coefficients for the IST-R clinical scales ranged from .69 to .91 (mean α = .84), and correlation coefficients were strongest for scales measuring the same constructs. Factor loadings obtained were consistent with those reported in the literature. Results support the internal consistency and construct validity of the IST-R. Culturally and linguistically appropriate assessment instruments are needed to address the mental health needs of diverse populations. Results from this study provide evidence for the clinical and research promise of the IST-R as a screening tool for trauma-related symptoms.

    2015-04-01

    Introduction The NER 300 programme, managed by the European Commission is one of the largest funding programmes for innovative low-carbon energy demonstration projects. NER 300 is so called because it is funded from the sale of 300 million emission allowances from the new entrants' reserve (NER) set up for the third phase of the EU emissions trading system (ETS). The programme aims to successfully demonstrate environmentally safe carbon capture and storage (CCS) and innovative renewable energy (RES) technologies on a commercial scale with a view to scaling up production of low-carbon technologies in the EU. Consequently, it supports a wide range of CCS and RES technologies (bioenergy, concentrated solar power, photovoltaics, geothermal, wind, ocean, hydropower, and smart grids). Funded projects and the role of geothermal projects for the programme In total, about EUR 2.1 billion have been awarded to 39 projects through the programme's 2 calls for proposals (the first awarded in December 2012, the second in July 2014). The programme has awarded around 70 mEUR funding to 3 geothermal projects in Hungary, Croatia and France (see Annex). The Hungarian geothermal project awarded funding under the first call will enter into operation at the end of 2015 and the rest are expected to start in 2016 (HR) and in 2018 (FR), respectively. Knowledge Sharing Knowledge sharing requirements are built into the legal basis of the programme as a critical tool to lower risks in bridging the transition to large-scale production of innovative renewable energy and CCS deployment. Projects have to submit annually to the European Commission relevant knowledge gained during that year in the implementation of their project. The relevant knowledge is aggregated and disseminated by the European Commission to industry, research, government, NGO and other interest groups and associations in order to provide a better understanding of the practical challenges that arise in the important step of scaling up technologies and operating them at commercial scale. The knowledge sharing of the NER 300 programme should lead to better planning and faster introduction of low carbon technologies in the future. Content of the presentation The presentation will introduce the geothermal projects that have been awarded funding, including their state-of-play. Insights and knowledge gained from the projects that have entered into operation will be shown and discussed. Furthermore, the presentation will provide an overview of the NER 300 programme.

  18. Sculpting the UMLS Refined Semantic Network

    Morrey, C. Paul; Perl, Yehoshua; Elhanan, Gai; Chen, Ling; Chen, Yan; Geller, James

    2014-01-01

    Background The Refined Semantic Network (RSN) for the UMLS was previously introduced to complement the UMLS Semantic Network (SN). The RSN partitions the UMLS Metathesaurus (META) into disjoint groups of concepts. Each such group is semantically uniform. However, the RSN was initially an order of magnitude larger than the SN, which is undesirable since to be useful, a semantic network should be compact. Most semantic types in the RSN represent combinations of semantic types in the UMLS SN. Such a “combination semantic type” is called Intersection Semantic Type (IST). Many ISTs are assigned to very few concepts. Moreover, when reviewing those concepts, many semantic type assignment inconsistencies were found. After correcting those inconsistencies many ISTs, among them some that contradicted UMLS rules, disappeared, which made the RSN smaller. Objective The authors performed a longitudinal study with the goal of reducing the size of the RSN to become compact. This goal was achieved by correcting inconsistencies and errors in the IST assignments in the UMLS, which additionally helped identify and correct ambiguities, inconsistencies, and errors in source terminologies widely used in the realm of public health. Methods In this paper, we discuss the process and steps employed in this longitudinal study and the intermediate results for different stages. The sculpting process includes removing redundant semantic type assignments, expanding semantic type assignments, and removing illegitimate ISTs by auditing ISTs of small extents. However, the emphasis of this paper is not on the auditing methodologies employed during the process, since they were introduced in earlier publications, but on the strategy of employing them in order to transform the RSN into a compact network. For this paper we also performed a comprehensive audit of 168 “small ISTs” in the 2013AA version of the UMLS to finalize the longitudinal study. Results Over the years it was found that the editors of the UMLS introduced some new inconsistencies that resulted in the reintroduction of unwarranted ISTs that had already been eliminated as a result of their previous corrections. Because of that, the transformation of the RSN into a compact network covering all necessary categories for the UMLS was slowed down. The corrections suggested by an audit of the 2013AA version of the UMLS achieve a compact RSN of equal magnitude as the UMLS SN. The number of ISTs has been reduced to 336. We also demonstrate how auditing the semantic type assignments of UMLS concepts can expose other modeling errors in the UMLS source terminologies, e.g., SNOMED CT, LOINC, and RxNORM that are important for health informatics. Such errors would otherwise stay hidden. Conclusions It is hoped that the UMLS curators will implement all required corrections and use the RSN along with the SN when maintaining and extending the UMLS. When used correctly, the RSN will support the prevention of the accidental introduction of inconsistent semantic type assignments into the UMLS. Furthermore, this way the RSN will support the exposure of other hidden errors and inconsistencies in health informatics terminologies, which are sources of the UMLS. Notably, the development of the RSN materializes the deeper, more refined Semantic Network for the UMLS that its designers envisioned originally but had not implemented. PMID:25422719

    Malaria vector control technology has remained largely static for decades and there is a pressing need for innovative control tools and methodology to radically improve the quality and efficiency of current vector control practices. This report summarizes a workshop jointly organized by the Innovative Vector Control Consortium (IVCC) and the Armed Forces Pest Management Board (AFPMB) focused on public health pesticide application technology. Three main topics were discussed: the limitations with current tools and techniques used for indoor residual spraying (IRS), technology innovation to improve efficacy of IRS programmes, and truly disruptive application technology beyond IRS. The group identified several opportunities to improve application technology to include: insuring all IRS programmes are using constant flow valves and erosion resistant tips; introducing compression sprayer improvements that help minimize pesticide waste and human error; and moving beyond IRS by embracing the potential for new larval source management techniques and next generation technology such as unmanned "smart" spray systems. The meeting served to lay the foundation for broader collaboration between the IVCC and AFPMB and partners in industry, the World Health Organization, the Bill and Melinda Gates Foundation and others.

  5. Autolytic activity of human calpain 7 is enhanced by ESCRT-III-related protein IST1 through MIT-MIM interaction.

    Calpain 7, a mammalian ortholog of yeast Cpl1/Rim13 and fungal PalB, is an atypical calpain that lacks a penta-EF-hand domain. Previously, we reported that a region containing a tandem repeat of microtubule-interacting and transport (MIT) domains in calpain 7 interacts with a subset of endosomal sorting complex required for transport (ESCRT)-III-related proteins, suggesting involvement of calpain 7 in the ESCRT system. Although yeast and fungal calpains are thought to be involved in alkaline adaptation via limited proteolysis of specific transcription factors, proteolytic activity of calpain 7 has not been demonstrated yet. In this study, we investigated the interaction between calpain 7 and a newly reported ESCRT-III family member, increased sodium tolerance-1 (IST1), which possesses two different types of MIT-interacting motifs (MIM1 and MIM2). We found that glutathione-S-transferase (GST)-fused tandem MIT domains of calpain 7 (calpain 7MIT) pulled down FLAG-tagged IST1 expressed in HEK293T cells. Coimmunoprecipitation assays with various deletion or point mutants of epitope-tagged calpain 7 and IST1 revealed that both repetitive MIT domains and MIMs are required for efficient interaction. Direct MIT-MIM binding was confirmed by a pulldown experiment with GST-fused IST1 MIM and purified recombinant calpain 7MIT. Furthermore, we found that the GST-MIM protein enhances the autolysis of purified Strep-tagged monomeric green fluorescent protein (mGFP)-fused calpain 7 (mGFP-calpain 7-Strep). The autolysis was almost completely abolished by 10 mmN-ethylmaleimide but only partially inhibited by 1 mm leupeptin or E-64. The putative catalytic Cys290-substituted mutant (mGFP-calpain 7(C290S)-Strep) showed no autolytic activity. These results demonstrate for the first time that human calpain 7 is proteolytically active, and imply that calpain 7 is activated in the ESCRT system. © 2010 The Authors Journal compilation © 2010 FEBS.

  6. Use and Limitations of a Climate-Quality Data Record to Study Temperature Trends on the Greenland Ice Sheet

    Enhanced melting of the Greenland Ice Sheet has been documented in recent literature along with surface-temperature increases measured using infrared satellite data since 1981. Using a recently-developed climate-quality data record, 11- and 12-year trends in the clear-sky ice-surface temperature (IST) of the Greenland Ice Sheet have been studied using the Moderate-Resolution Imaging Spectroradiometer (MODIS) IST product. Daily and monthly MODIS ISTs of the Greenland Ice Sheet beginning on 1 March 2000 and continuing through 31 December 2010 are now available at 6.25-km spatial resolution on a polar stereographic grid as described in Hall et al. (submitted). This record will be elevated in status to a climate-data record (CDR) when more years of data become available either from the MODIS on the Terra or Aqua satellites, or from the Visible Infrared Imager Radiometer Suite (VIIRS) to be launched in October 2011. Maps showing the maximum extent of melt for the entire ice sheet and for the six major drainage basins have been developed from the MODIS IST dataset. Twelve-year trends in the extent of melt and duration of the melt season on the ice sheet vary in different drainage basins with some basins melting progressively earlier over the course of the study period. Some (but not all) of the basins also show a progressively-longer duration of melt. Twelve-year trends in IST are compared with in-situ data, and climate data from the Modern Era Retrospective-Analysis for Research and Applications (MERRA) Reanalysis. Hall, D.K., J.C. Comiso, N.E.

    This is a single centre experience on the use of immunosuppressive therapy (IST) and stem cell transplantation (SCT) in patients with aplastic anaemia. Between 1985 and December 2013, 530 patients underwent IST while 214 underwent allogeneic SCT. Overall response rate with the use of IST was 58% with higher responses seen in adults (65.1%) compared to children (35.8%) [p = 0.001]. At a median follow up of 34 months (range: 1 - 264), 5 year KM estimates for OS for the entire group is 68.2 ± 2.2%. Loss of response or relapse was seen in 27 responders while clonal evolution to PNH was seen in 8 patients and transformation to MDS or AML was seen in 3. The 5 yr OS for children (45.7 ± 4.7%) was significantly lower than the OS of age groups 16-30 (75.6 ± 3.6%), 31-50 years (76.2 ± 4.2%) and > 50 years (73.0 ±4.2%) (p = 0.0001). SCT was performed in 214 patients with engraftment seen in 91%. The incidence of grade II-IV acute graft versus host disease (GVHD) was 38.4% with grade III-IV GVHD in 11.7%. Chronic GVHD was seen in 47.5% of evaluable patients with majority (73%) being limited chronic GVHD. At a median follow up of 32 months (range: 1 - 244), the 5 year KM estimates of OS for the entire cohort is 64.8 ± 3.3%); The 5 yr OS was significantly higher with the use of Flu/Cy (5 yr OS of 73.8 ± 3.6%) compared to Cy/ATG (5 yr OS of 44.4 ± 9.6%) or Flu/Bu conditioning (5 yr OS of 52.4 ± 8.9%) [p = 0.001]. Imp: SCT and IST offer good response rates and survival in Indian patients with AA except in children receiving IST.

    Objective: To determine whether cyclosporine A (CsA) plus androgens was as effective as the current standard immunosuppressive therapy (IST) for transfusion-dependent nonsevere aplastic anemia (TD-NSAA). Methods: The records of 125 consecutive TD-NSAA patients who were treated between Aug. 2007 and Sept. 2014, with either CsA plus androgen or ALG/ATG plus CsA regimen were reviewed. The 3-month and 6-month hematologic responses and survival were evaluated. Results: There were 125 TD-NSAA patients (70 were male and 55 female, 1.25∶1). Median age was 27 (6-66) years. There was no significant difference in early mortality between 48 treated by ATG/ALG plus CsA and 77 by CsA plus androgen patients (1/48 vs 0/77, P =0.384). Both the total hematologic response and the better hematological response rates at 3-month (70.8% vs 45.5%, P =0.006 and 27.1% vs 10.4%, P =0.015, respectively) and 6-month (75.0% vs 55.8%, P =0.031 and 41.7% vs 22.1% P =0.020, respectively) after treatment were much higher in the standard IST group than that in CsA plus androgen group. The median time to transfusion independent of 36.5 (0-149) days in the standard IST group was significantly shorter than 98 (14-180) days in CsA plus androgen group ( P <0.001). Survival was comparable between the two groups (97.9% vs 100.0%, P =0.227). It was superior (71.2% vs 59.5%) but not significantly ( P =0.227) in event-free survival in standard IST group. Conclusions: CsA plus androgen was inferior to the standard IST of ATG/ALG and CsA regimen in treating TD-NSAA in terms of the hematologic response and the quality of response, despite of comparable short-term survival.

    2014-11-01

    The European Commission recently published the first calls for proposals for the Horizon 2020 (H2020) work programme for research and innovation. When browsing through the Health programme, it became apparent that the work programme made little reference to environmental health research. In this commentary we describe major milestones of environmental health research in previous European Framework Programmes and the policy shift that took place when preparing H2020. We introduce mobile health technologies as a niche innovation to reconcile the environmental health research arena with the H2020 programme that has a clear focus on ICT. The recent economic crises urged strong policy action to reinforce Europe's economic and innovation leadership. Market-driven and job-creating ambitions became primary goals of H2020. Environmental health-related keywords referring to, e.g. human biomonitoring, exposure assessment or exposome are absent in the current H2020-calls and this may suggest a lack of opportunities for environmental health researchers. Technologies related to mobile healthcare (mhealth) are rapidly maturing and offer new research and market opportunities. In a typically technology-pushed market, these sensor technologies however require validation by a third-party and implementation in large-scale public health monitoring studies. Also, issues related to data protection need further development to warrant user rights and privacy. If the European environmental health research arena succeeds in embracing these new mhealth sensor technologies, it may not only create an opportunity to play a role as a key innovation partner in health transition technologies, but it may also support authorities to realize a transition in our healthcare with a much bigger emphasis on a preventive and sustainable system.

    In the framework of its research and development activities, the European Space Agency (ESA) spends some 250m each year and, recognizing the enormous potential of the know-how developed within its R&D activities, set up a Technology Transfer Programme (TTP) some twelve years ago. Over the years, the Programme has achieved some remarkable results with 120 successful transfers of space technologies to the non-space sector; over 120m received by companies making the technologies available; some 15 new companies established as a direct result of exploiting technologies; nearly 2500 jobs created or saved in Europe; and a portfolio of some 300 (out of over 600) active space technologies available for transfer and licencing. Some of the more recent technologies which have been successfully transferred to the non-space sector include the Mamagoose baby safety pyjamas; a spectrographic system being used to compare colours in fabrics and textiles; Earth observation technology employed to assess remotely how much agrochemicals are being used by farmers; and the Dutch solar car, Nuna, which, using European space technologies, finished first in the 2001 World Solar Challenge breaking all records. The paper will give a brief overview of the ESA Technology Transfer Programme and describe some of its recent successful technology transfers.

    We present an inverse scattering transform (IST) approach for the (differentiated) Ostrovsky-Vakhnenko equation This equation can also be viewed as the short wave model for the Degasperis-Procesi (sDP) equation. Our IST approach is based on an associated Riemann-Hilbert problem, which allows us to give a representation for the classical (smooth) solution, to get the principal term of its long time asymptotics, and also to describe loop soliton solutions.

    1993-10-01

    Transfer of technology is a complex process with many facets, options and constraints. While the concept is an important step in bringing industrialization process to agricultural based countries, it is clear, however, that a country will only benefit from a new technology if it addresses a real need, and if it can be absorbed and adapted to suit the existing cultural and technological base. International Atomic Energy Agency, as UN body, has a mandate to promote nuclear applicationsand assist Member States in transfer of technology for peaceful applications. This mandate has been pursued by many different mechanisms developed in the past years: technical assistance, coordinated research programmes, scientific and technical meetings, publications, etc. In all these activities the Agency is the organizer and initiator, but main contributions come from expert services from developed countries and, increasingly, from developing countries themselves. The technical cooperation among developing coutries more and more becomes part of different programmes. In particular, regional cooperation has been demonstrated as an effective instrument for transfer of technology from developed and among developing countries. Some examples of actual programmes are given.

    The remote laboratories at IST (Instituto Superior Tecnico), e-lab, serve as a valuable tool for education and training based on remote control technologies. Due to the high number and increase of remotely operated experiments a generic protocol was developed to perform the communication between the software driver and the respective experimental setup in an easier and more unified way. The training in these fields of students and personnel can take advantage of such infrastructure with the purpose of deploying new experiments in a faster way. More than 10 experiments using the generic protocol are available on-line in a 24 xmore » 7 way. (authors)« less

    To determine whether patients with stroke receiving rehabilitation for upper limb deficits using smart technology (video and reminder functions) demonstrate greater adherence to prescribed home exercise programmes and better functional outcomes when compared with traditional paper-based exercise prescription. Randomized controlled trial comparing upper limb home exercise programmes supported by video and automated reminders on smart technology, with standard paper-based home exercise programmes. A community rehabilitation programme within a large metropolitan health service. Patients with stroke with upper limb deficits, referred for outpatient rehabilitation. Participants were randomly assigned to the control (paper-based home exercise programme) or intervention group (home exercise programme filmed on an electronic tablet, with an automated reminder). Both groups completed their prescribed home exercise programme for four weeks. The primary outcome was adherence using a self-reported log book. Secondary outcomes were change in upper limb function and patient satisfaction. A total of 62 participants were allocated to the intervention ( n = 30) and control groups ( n = 32). There were no differences between the groups for measures of adherence (mean difference 2%, 95% CI -12 to 17) or change in the Wolf Motor Function Test log transformed time (mean difference 0.02 seconds, 95% CI -0.1 to 0.1). There were no between-group differences in how participants found instructions ( p = 0.452), whether they remembered to do their exercises ( p = 0.485), or whether they enjoyed doing their exercises ( p = 0.864). The use of smart technology was not superior to standard paper-based home exercise programmes for patients recovering from stroke. This trial design was registered prospectively with the Australian and New Zealand Clinical Trials Register, ID: ACTRN 12613000786796. http://www.anzctr.org.au/trialSearch.aspx.

    The @neurIST ontology is currently under development within the scope of the European project @neurIST intended to serve as a module in a complex architecture aiming at providing a better understanding and management of intracranial aneurysms and subarachnoid hemorrhages. Due to the integrative structure of the project the ontology needs to represent entities from various disciplines on a large spatial and temporal scale. Initial term acquisition was performed by exploiting a database scaffold, literature analysis and communications with domain experts. The ontology design is based on the DOLCE upper ontology and other existing domain ontologies were linked or partly included whenever appropriate (e.g., the FMA for anatomical entities and the UMLS for definitions and lexical information). About 2300 predominantly medical entities were represented but also a multitude of biomolecular, epidemiological, and hemodynamic entities. The usage of the ontology in the project comprises terminological control, text mining, annotation, and data mediation. PMID:18693797

    2012-01-07

    Sodium polyacrylate-induced pH pattern formation and starch-induced iodine pattern formation were investigated in the iodate-sulfite-thiosulfate (IST) reaction in a one-side fed disc gel reactor (OSFR). As binding agents of the autocatalyst of hydrogen ions or iodide ions, different content of sodium polyacrylate or starch has induced various types of pattern formation. We observed pH pulses, striped patterns, mixed spots and stripes, and hexagonal spots upon increasing the content of sodium polyacrylate and observed iodine pulses, branched patterns, and labyrinthine patterns upon increasing the starch content in the system. Coexistence of a pH front and an iodine front was also studied in a batch IST reaction-diffusion system. Both pH and iodine front instabilities were observed in the presence of sodium polyacrylate, i.e., cellular fronts and transient Turing structures resulting from the decrease in diffusion coefficients of activators. The mechanism of multiple feedback may explain the different patterns in the IST reaction-diffusion system.

  5. Epsilon-near-zero modes for tailored light-matter interaction

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Campione, Salvatore; Liu, Sheng; Benz, Alexander

    Epsilon-near-zero (ENZ) modes arising from condensed-matter excitations such as phonons and plasmons are a new path for tailoring light-matter interactions at the nanoscale. Complex spectral shaping can be achieved by creating such modes in nanoscale semiconductor layers and controlling their interaction with multiple, distinct, dipole resonant systems. Examples of this behavior are presented at midinfrared frequencies for ENZ modes that are strongly coupled to metamaterial resonators and simultaneously strongly coupled to semiconductor phonons or quantum-well intersubband transitions (ISTs), resulting in double- and triple-polariton branches in transmission spectra. For the double-polariton branch case, we find that the best strategy to maximizemore » the Rabi splitting is to use a combination of a doped layer supporting an ENZ feature and a layer supporting ISTs, with overlapping ENZ and IST frequencies. As a result, this design flexibility renders this platform attractive for low-voltage tunable filters, light-emitting diodes, and efficient nonlinear composite materials.« less

  6. Zahlen und Rechenvorgänge auf unterschiedlichen Abstraktionsniveaus

    NASA Astrophysics Data System (ADS)

    Rödler, Klaus

    "Das Verständnis geht langsam vor sich!" Diesen wichtigen Satz hörte ich bei einem Vortrag von Martin Lowsky. Auf die hier behandelte Fragestellung übertragen heißt das: Was eine Zahl ist und wie ich sie im Rechenvorgang einsetzen und interpretieren kann, das erschließt sich erst allmählich. Die Zahl des Rechenanfängers ist nicht dieselbe wie die des kompetenten Rechners und es ist nicht die Zahl des Lehrers oder der Lehrerin. Die Zahlen sind nur auf der Oberfläche der Worte und Zeichen gleich. Im Innern, im Verständnis, sind sie völlig verschieden! Ich glaube, dass die Missachtung dieser Divergenz dazu führt, dass manche Kinder in für den Lehrer und Lehrerin nicht nachvollziehbaren Routinen stecken bleiben, einfachste Informationen nicht wirklich integrieren. Die auf beiden Seiten wachsende Verunsicherung durch die nicht erkannte und daher nicht kommunizierbare Diskrepanz im inneren Zahlkonzept stört den allmählichen Aufbau strukturierter Zahlvorstellungen.

  8. Theoretical analysis of cross-talking signals between counter-streaming electron beams in a vacuum tube oscillator

    Shin, Y. M.; Ryskin, N. M.; Won, J. H.; Han, S. T.; Park, G. S.

    2006-03-01

    The basic theory of cross-talking signals between counter-streaming electron beams in a vacuum tube oscillator consisting of two two-cavity klystron amplifiers reversely coupled through input/output slots is theoretically investigated. Application of Kirchhoff's laws to the coupled equivalent RLC circuit model of the device provides four nonlinear coupled equations, which are the first-order time-delayed differential equations. Analytical solutions obtained through linearization of the equations provide oscillation frequencies and thresholds of four fundamental eigenstates, symmetric/antisymmetric 0/π modes. Time-dependent output signals are numerically analyzed with variation of the beam current, and a self-modulation mechanism and transition to chaos scenario are examined. The oscillator shows a much stronger multistability compared to a delayed feedback klystron oscillator owing to the competitions among more diverse eigenmodes. A fully developed chaos region also appears at a relatively lower beam current, ˜3.5Ist, compared to typical vacuum tube oscillators (10-100Ist), where Ist is a start-oscillation current.

    The Endosomal Sorting Complexes Required for Transport (ESCRT) proteins mediate fundamental membrane remodeling events that require stabilizing negative membrane curvature. These include endosomal intralumenal vesicle formation, HIV budding, nuclear envelope closure and cytokinetic abscission. ESCRT-III subunits perform key roles in these processes by changing conformation and polymerizing into membrane-remodeling filaments. Here, we report the 4 Å resolution cryo-EM reconstruction of a one-start, double-stranded helical copolymer composed of two different human ESCRT-III subunits, CHMP1B and IST1. The inner strand comprises “open” CHMP1B subunits that interlock in an elaborate domain-swapped architecture, and is encircled by an outer strand of “closed” IST1 subunits. Unlike other ESCRT-III proteins, CHMP1B and IST1 polymers form external coats on positively-curved membranes in vitro and in vivo. Our analysis suggests how common ESCRT-III filament architectures could stabilize different degrees and directions of membrane curvature. PMID:26634441

    The significance of paroxysmal nocturnal haemoglobinuria (PNH(pos) ) cells and leucocyte subset telomere lengths in paediatric aplastic anaemia (AA) is unknown. Among 22 children receiving immunosuppressive therapy (IST) for AA, 73% (16/22) were PNH(pos) , of whom 94% achieved at least a partial response (PR) to IST; 11/16 (69%) achieved complete response (CR). Only 2/6 (33%) PNH(neg) patients achieved PR. PNH(pos) patients were less likely to fail IST compared to PNH(neg) patients (odds ratio 0·033; 95% confidence interval 0·002-0·468; P = 0·012). Children with AA had short granulocyte (P = 7·8 × 10(-9) ), natural killer cell (P = 6·0 × 10(-4) ), naïve T lymphocyte (P = 0·002) and B lymphocyte (P = 0·005) telomeres compared to age-matched normative data. © 2013 John Wiley & Sons Ltd.

  11. "Das Konkrete ist das Abstrakte, an das man sich schließlich gewöhnt hat." (Laurent Schwartz) Über den Ablauf des mathematischen Verstehens

    Lowsky, Martin

    Die im Titel genannte Aussage findet sich in den Lebenserinnerungen von Laurent Schwartz (1915-2002), einem der fruchtbarsten Mathematiker, Mitglied der Gruppe Bourbaki. Im Original lautet die Aussage: "un objet concret est un objet abstrait auquel on a fini par s'habituer." Schwartz erläutert sie am Beispiel des Integrals über {e^{-1/2{x^2}}} , das den Wert Wurzel aus 2π hat und in dem sich also die Zahlen e und π verknüpfen. Was Schwartz aber vor allem ausdrücken will, ist dies: Das mathematische Verständnisd geht langsam vor sich und es bedarf der Anstrengung. "Es ist eine Frage der Zeit und der Energie", sagt Schwartz, und gerade dies mache es so schwer, die höhere Mathematik unter das Volk zu bringen. Das Lernen und Lehren von Mathematik laufe eben mühevoll und langsam ab.

  12. IMMUNO-SPIN TRAPPING FROM BIOCHEMISTRY TO MEDICINE: advances, challenges, and pitfalls

    BACKGROUND Immuno-spin trapping (IST) is based on the reaction of a spin trap with a free radical to form a stable nitrone adduct, followed by the use of antibodies, rather than traditional electron paramagnetic resonance spectroscopy, to detect the nitrone adduct. IST has been successfully applied to mechanistic in vitro studies, and recently, macromolecule-centered radicals have been detected in models of drug-induced agranulocytosis, hepatotoxicity, cardiotoxicity, and ischemia/reperfusion, as well as in models of neurological, metabolic and immunological diseases. SCOPE OF THE REVIEW To critically evaluate advances, challenges, and pitfalls as well as the scientific opportunities of IST as applied to the study of protein-centered free radicals generated in stressed organelles, cells, tissues and animal models of disease and exposure. MAJOR CONCLUSIONS Because the spin trap has to be present at high enough concentrations in the microenvironment where the radical is formed, the possible effects of the spin trap on gene expression, metabolism and cell physiology have to be considered in the use of IST and in the interpretation of results. These factors have not yet been thoroughly dealt with in the literature. GENERAL SIGNIFICANCE The identification of radicalized proteins during cell/tissue response to stressors will help define their role in the complex cellular response to stressors and pathogenesis; however, the fidelity of spin trapping/ immuno-detection and the effects of the spin trap on the biological system should be considered.

    We investigated the frequencies of cytogenetic aberrations and somatic mutations of prognostic relevance in 393 patients with aplastic anaemia (AA). Clonality was determined by G-banding/fluorescence in situ hybridization (FISH) (n = 245), and targeted capture sequencing was performed for 88 haematopoiesis-related genes (n = 70). The telomere length (TL) of bone marrow nucleated cells was measured at the single cell level by FISH (n = 135). Eighteen (4·6%) patients showed disease progression, and monosomy 7 (50·0%) was the most predominant cytogenetic evolution at disease transformation. One third of patients (32·9%) presented at least 1 mutation; the most frequently mutated genes were NOTCH1, NF1, SCRIB, BCOR and DNMT3A. The patient group with clonal changes (30·7%) showed an adverse response to immunosuppressive treatment (IST), compared to the non-clonal group, but this finding did not show statistical significance. The TL of AA patients was significantly shorter than normal control and patients with clonal changes showed significantly shorter TLs. Patients with TL>5·9 showed a higher response rate to IST (P = 0·048). In conclusion, the patients with clonal changes or TL attrition showed a poor response to IST. Shorter TL can be used not only as a biomarker, but also as a predictive marker for treatment response to IST. © 2017 John Wiley & Sons Ltd.

    In this study, a new physics education programme is specifically developed for a famous theme park in Hong Kong to provide community-based science learning to her visitors, involving her three newly constructed rides. We make innovative use of digital technologies in this programme and incorporate a rigorous evaluation of the learning effectiveness of the programme. A total of around 200 students from nine local secondary schools participated in both the physics programme and its subsequent evaluation which consists of a combination of research and assessment tools, including pre- and post-multiple-choice tests, a questionnaire survey and an interview as specifically developed for this programme, or adopted from some well-accepted research instruments. Based on the evaluation of students' academic performance, there are two educationally significant findings on enhancing the students' physics learning: (a) traditionally large gender differences in physics performance and interest of learning are mostly eliminated; and (b) a less-exciting ride called the aviator (instead of the most exciting roller-coaster ride) can induce the largest learning effect (or gain in academic performance) amongst teenagers. Besides, findings from the questionnaire survey and interviews of participants are reported to reveal their views, perceptions, positive and negative comments or feedback on this programme which could provide valuable insights for future development of other similar community-based programmes.

  15. A case study of intersections between a physics classroom and industry

    Jadonath, Capildeo

    The purpose of this study was to describe a journey for one teacher and his students. This journey involved bridging the gap between his classroom and high-tech workplaces, while engaging students in an integrated physics curriculum called Advanced Technology Education (ATE). This integrated curriculum is grounded in physics and interwoven with both Principles of Technology (PT) and Integrated Systems Technology (IST). ATE integrates the learning of technical skills, people skills, and academics through real world applications in manufacturing, production and engineering technology. The study was qualitative and employed a specific genre of research, the case study and it included both qualitative and quantitative data collection. This case study design originated from anthropology and has the following four characteristics: particularistic, descriptive, heuristic, and inductive. Data were collected over a 2-year period (August 1996-June 1998), by the researcher who was simultaneously the participants' instructor. This allowed me to be the prime instrument for the study and also become an "insider". The techniques of data collection were guided primarily by the research questions. Multiple sources of evidence included: documents, interviews, archival records, direct observations, participant observations, physical artifacts, and surveys (students, parents, and faculty).

    In 2010, the US Food and Drug Administration (Silver Spring, Maryland USA) created the Medical Countermeasures Initiative with the mission of development and promoting medical countermeasures that would be needed to protect the nation from identified, high-priority chemical, biological, radiological, or nuclear (CBRN) threats and emerging infectious diseases. The aim of this review was to promote regulatory science research of medical devices and to analyze how the devices can be employed in different CBRN scenarios. Triage in CBRN scenarios presents unique challenges for first responders because the effects of CBRN agents and the clinical presentations of casualties at each triage stage can vary. The uniqueness of a CBRN event can render standard patient monitoring medical device and conventional triage algorithms ineffective. Despite the challenges, there have been recent advances in CBRN triage technology that include: novel technologies; mobile medical applications ("medical apps") for CBRN disasters; electronic triage tags, such as eTriage; diagnostic field devices, such as the Joint Biological Agent Identification System; and decision support systems, such as the Chemical Hazards Emergency Medical Management Intelligent Syndromes Tool (CHEMM-IST). Further research and medical device validation can help to advance prehospital triage technology for CBRN events.

    The National Institute for Health and Care Excellence (NICE) Medical Technologies Evaluation Programme (MTEP) promotes the adoption of innovative diagnostic and therapeutic technologies into National Health Service (NHS) clinical practice through the publication of guidance and briefing documents. Since the inception of the programme in 2009, there have been 7 medical technologiesguidance, 3 diagnostics guidance and 23 medtechinnovation briefing documents published that are relevant to the heart and circulation. Medical technologies guidance is published by NICE for selected single technologies if they offer plausible additional benefits to patients and the healthcare system. Diagnostic guidance is published for diagnostic technologies if they have the potential to improve health outcomes, but if their introduction may be associated with an increase in overall cost to the NHS. Medtechinnovation briefings provide evidence-based advice to those considering the implementation of new medical devices or diagnostic technologies. This review provides reference to all of the guidance and briefing medical technology documents that NICE has published that are relevant to the heart and circulation and reflect on their diverse recommendations. The interaction of MTEP with other NICE programmes is integral to its effectiveness and the means by which consistency is ensured across the different NICE programmes is described. The importance of the input of clinical experts from the cardiovascular professional community and the engagement by NICE with cardiovascular professional societies is highlighted as being fundamental to ensuring the quality of guidance outputs as well as to promoting their implementation and adoption. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Die Detektion von Hindernissen vor dem Automobil ist eine Hauptanforderung an moderne Fahrerassistenzsysteme (FAS). In dieser Arbeit wird ein System vorgestellt, das mit Hilfe einer PMDKamera (Photomischdetektor) Hindernisse auf der Fahrspur erkennt und deren relevante Parameter bestimmt. Durch die PMD-Kamera werden zunächst 3D-Tiefenbilder der Fahrzeugumwelt generiert. Nach einem initialen Filterprozess werden im Tiefenbild mit Hilfe eines Bereichswachstumsverfahrens Hindernisse gesucht. Zur Stabilisierung des Verfahrens und zur Parameterberechnung wird ein Kaiman Filter eingesetzt. Das Ergebnis ist eine Liste aller Hindernisse im Fahrbereich des Automobils.

    2015-01-01

    Cervical cancer remains the second most common cancer for women worldwide and is the cancer priority in most low- and middle-income countries (LMIC). The development of vaccines against the human papilloma virus (HPV) and the impact of technology both for the detection of HPV and cervical cancer represent milestones and new opportunities in prevention.

    HELI-DEM (Helvetia-Italy Digital Elevation Model) is a project developed in the framework of Italy/Switzerland Operational Programme for Trans-frontier Cooperation 2007-2013 whose major aim is to create a unified digital terrain model that includes the alpine and sub-alpine areas between Italy and Switzerland. The partners of the project are: Lombardy Region, Piedmont Region, Polytechnic of Milan, Polytechnic of Turin and Fondazione Politecnico from Italy; Institute of Earth Sciences (SUPSI) from Switzerland. The digital terrain model has been produced by integrating and validating the different elevation data available for the areas of interest, characterized by different reference frame, resolutions and accuracies: DHM at 25 m resolution from Swisstopo, DTM at 20 m resolution from Lombardy Region, DTM at 5 m resolution from Piedmont Region and DTM LiDAR PST-A at about 1 m resolution, that covers the main river bed areas and is produced by the Italian Ministry of the Environment. Further results of the project are: the generation of a unique Italian Swiss geoid with an accuracy of few centimeters (Gilardoni et al. 2012); the establishment of a GNSS permanent network, prototype of a transnational positioning service; the development of a geo-portal, entirely based on open source technologies and open standards, which provides the cross-border DTM and offers some capabilities of analysis and processing through the Internet. With this talk, the authors want to present the main steps of the project with a focus on the HELI-DEM geo-portal development carried out by the Institute of Earth Sciences, which is the access point to the DTM outputted from the project. The portal, accessible at http://geoservice.ist.supsi.ch/helidem, is a demonstration of open source technologies combined for providing access to geospatial functionalities to wide non GIS expert public. In fact, the system is entirely developed using only Open Standards and Free and Open Source Software (FOSS) both on the server side (services) and on the client side (interface). In addition to self developed code the system relies mainly on teh software GRASS 7 [1], ZOO-project [2], Geoserver [3] and OpenLayers [4] and the standards WMS [5], WCS [6] and WPS [7]. At the time of writing, the portal offers features like profiling, contour extraction, watershed delineation and analysis, derivatives calculation, data extraction, coordinate conversion but it is evolving and it is planned to extend to a series of environmental modeling that the IST developed in the past like dam break simulation, landslide run-out estimation and floods due to landslide impact in artificial basins.

    Aplastic anemia (AA) is characterized by pancytopenia and bone marrow failure, and most acquired AA is an immune-mediated disorder. Regulatory T cells (T regs ) suppressing autoreactive T cells were decreased in AA patients. FoxP3 is a major regulator for the development and function of T regs . Polymorphism in FoxP3 was shown to be associated with various autoimmune diseases, however, has not yet been studied in AA. In this study, we examined the association between FoxP3 polymorphisms and AA in Korean patients. The study population consisted of 94 patients diagnosed by bone marrow examination in Seoul National University Hospital (SNUH) during 1997-2012 and 195 healthy controls. FoxP3 polymorphisms (rs5902434 del/ATT, rs3761548 C/A, rs3761549 C/T, rs2232365 A/G) were analyzed by PCR-sequencing method. We analyzed differences of genotype and allele frequencies between patients and controls. We also compared differences of genotype and allele frequencies between responder and non-responder in patients treated with immunosuppressive therapy (IST). For the statistical analysis, the chi-square test and Fisher's exact test were used and P < 0.05 was regarded as statistically significant. There was no significant difference in the genotype frequencies of FoxP3 polymorphisms between patients and controls. With regards to the allele frequencies, rs3761548 C allele was significantly higher in AA patients than in controls (87.4% vs. 79.7%, P = 0.047). In patients treated with IST, rs3761549 C allele was significantly higher in non-responder patients than in responders (89.6% vs. 66.7%, P = 0.036) and female rs3761549 C/C genotype carriers were associated with greater risk for non-response to IST (84.2% vs. 16.7%, P = 0.006). Polymorphisms in rs3761548 and rs3761549 of FoxP3 in our population were associated with disease susceptibility and response for IST, respectively. This study suggests an association between FoxP3 polymorphisms and AA in Korean patients and will be useful in further understanding the genetic basis of disease susceptibility and response to IST in AA patients.

  20. Validation of a Climate-Data Record of the "Clear-Sky" Surface Temperature of the Greenland Ice Sheet

    Surface temperatures on the Greenland Ice Sheet have been studied on the ground, using automatic weather station (AWS) data from the Greenland-Climate Network (GC-Net), and from analysis of satellite sensor data. Using Advanced Very High Frequency Radiometer (AVHRR) weekly surface temperature maps, warming of the surface of the Greenland Ice Sheet has been documented since 1981. We extended and refined this record using higher-resolution Moderate-Resolution Imaging Spectroradiometer (MODIS) data from March 2000 to the present. We developed a daily and monthly climate-data record (CDR) of the "clear-sky" surface temperature of the Greenland Ice Sheet using an ice-surface temperature (1ST) algorithm developed for use with MODIS data. Validation of this CDR is ongoing. MODIS Terra swath data are projected onto a polar stereographic grid at 6.25-km resolution to develop binary, gridded daily and mean-monthly 1ST maps. Each monthly map also has a color-coded image map that is available to download. Also included with the monthly maps is an accompanying map showing number of days in the month that were used to calculate the mean-monthly 1ST. This is important because no 1ST decision is made by the algorithm for cells that are considered cloudy by the internal cloud mask, so a sufficient number of days must be available to produce a mean 1ST for each grid cell. Validation of the CDR consists of several facets: 1) comparisons between ISTs and in-situ measurements; 2) comparisons between ISTs and AWS data; and 3) comparisons of ISTs with surface temperatures derived from other satellite instruments such as the Thermal Emission and Reflection Radiometer (ASTER) and Enhanced Thematic Mapper Plus (ETM+). Previous work shows that Terra MODIS ISTs are about 3 C lower than in-situ temperatures measured at Summit Camp, during the winter of 2008-09 under clear skies. In this work we begin to compare surface temperatures derived from AWS data with ISTs from the MODIS CDR.

    Technology is developed at the European Space Agency (ESA) under several programmes: corporate and domain specific, mandatory and optional, with different time horizons and covering different levels of the TRL scale. To improve the transparency and efficiency of the complete process, it was felt necessary to establish an agreed end to end process for the management of all technology R&D activity that could: Include all ESA programmes and consider the requirements of European users Lead to coordinated multi-year work plan and yearly procurement plans Prepare and enable future European space programmes Be harmonized with national initiatives in Europe Thereby establishing the basis for a product policy to reduce risks to technology users, reduce costs and delays, and enhance industrial competitiveness and non-dependence. In response to the above needs, ESA has developed a technology management process called the ESA End-to-End process (E2E), from establishment of the strategy to the monitoring and evaluation of R&D results. In this paper, the complete process will be described in detail including a discussion on its strengths and limitations, and its links to the wider European Harmonization process. The paper will be concluded with the introduction of the ESA Technology Tree: a basic tool to structure and facilitate communication about technology issues.

    Wund-D.A.CH. ist der Dachverband deutschsprachiger Fachgesellschaften, die sich mit den Thematiken der Wundbehandlung beschäftigen. Experten verschiedener Fachgesellschaften aus Deutschland, Österreich und der Schweiz haben nun einen aktuellen Konsens der Kompressionstherapie für Patienten mit Ulcus cruris venosum erstellt. In Europa ist das Ulcus cruris venosum eine der häufigsten Ursachen für chronische Wunden. Neben der konservativen und interventionellen Wund- und Venentherapie, ist die Kompressionstherapie die Basis der Behandlungsstrategien. Die Kompressionstherapie kann heute mit sehr unterschiedlichen Materialien und Systemen durchgeführt werden. Während in der Entstauungsphase insbesondere Verbände mit Kurzzugbinden oder Mehrkomponentensysteme zur Anwendung kommen, sind es anschließend überwiegend Ulkus-Strumpfsysteme. Eine weitere, bislang wenig verbreitete Alternative sind adaptive Kompressionsbandagen. Insbesondere für die Rezidivprophylaxe werden medizinische Kompressionsstrümpfe empfohlen. Durch die Vielzahl der heute zur Verfügung stehenden Behandlungsoptionen, kann für nahezu alle Patienten ein Konzept entwickelt werden, dass sich an den individuellen Bedürfnissen und Fähigkeiten orientiert und daher auch akzeptiert und durchgeführt wird. Die Kompressionstherapie ist für die Behandlung von Patienten mit Ulcus cruris venosum essentiell. In den letzten Jahren sind viele verschiedene Therapieoptionen verfügbar, die in den deutschsprachigen Ländern unterschiedlich angewendet oder durchgeführt werden. Daher soll dieser Expertenkonsens dazu beitragen, konkrete Empfehlungen für die praktische Durchführung der Kompressionstherapie von Patienten mit Ulcus cruris venosum darzustellen. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

  3. Local structure of amorphous Ag5In5Sb60Te30 and In3SbTe2 phase change materials revealed by X-ray photoelectron and Raman spectroscopic studies

    Reversible switching between highly resistive (binary "0") amorphous phase and low resistive (binary "1") crystalline phase of chalcogenide-based Phase Change Materials is accredited for the development of next generation high-speed, non-volatile, data storage applications. The doped Sb-Te based materials have shown enhanced electrical/optical properties, compared to Ge-Sb-Te family for high-speed memory devices. We report here the local atomic structure of as-deposited amorphous Ag5In5Sb60Te30 (AIST) and In3SbTe2 (IST) phase change materials using X-ray photoelectron and Raman spectroscopic studies. Although AIST and IST materials show identical crystallization behavior, they differ distinctly in their crystallization temperatures. Our experimental results demonstrate that the local environment of In remains identical in the amorphous phase of both AIST and IST material, irrespective of its atomic fraction. In bonds with Sb (˜44%) and Te (˜56%), thereby forming the primary matrix in IST with a very few Sb-Te bonds. Sb2Te constructs the base matrix for AIST (˜63%) along with few Sb-Sb bonds. Furthermore, an interesting assimilation of the role of small-scale dopants such as Ag and In in AIST, reveals rare bonds between themselves, while showing selective substitution in the vicinity of Sb and Te. This results in increased electronegativity difference, and consequently, the bond strength is recognized as the factor rendering stability in amorphous AIST.

  4. Development of a Climate-Data Record (CDR) of the Surface Temperature of the Greenland Ice Sheet

    Regional "clear sky" surface temperature increases since the early 1980s in the Arctic, measured using Advanced Very High Resolution Radiometer (AVHRR) infrared data, range from 0.57+/-0.02 deg C to 72+/-0.10 deg C per decade. Arctic warming has important implications for ice-sheet mass balance because much of the periphery of the Greenland Ice Sheet is already near 0 deg C during the melt season, and is thus vulnerable to rapid melting if temperatures continue to increase. An increase in melting of the ice sheet would accelerate sea-level rise, an issue affecting potentially billions of people worldwide. To quantify the ice-surface temperature (IST) of the Greenland Ice Sheet, and to provide an IST dataset of Greenland for modelers that provides uncertainties, we are developing a climate-data record (CDR) of daily "clear-sky" IST of the Greenland Ice Sheet, from 1982 to the present using AVHRR (1982 - present) and Moderate-Resolution Imaging Spectroradiometer (MODIS) data (2000 - present) at a resolution of approximately 5 km. Known issues being addressed in the production of the CDR are: time-series bias caused by cloud cover (surface temperatures can be different under clouds vs. clear areas) and cross-calibration in the overlap period between AVHRR instruments, and between AVHRR and MODIS instruments. Because of uncertainties, mainly due to clouds, time-series of satellite IST do not necessarily correspond with actual surface temperatures. The CDR will be validated by comparing results with automatic-weather station data and with satellite-derived surface-temperature products and biases will be calculated.

  5. Microbial iron redox cycling in a circumneutral-pH groundwater seep.

    2009-01-01

    The potential for microbially mediated redox cycling of iron (Fe) in a circumneutral-pH groundwater seep in north central Alabama was studied. Incubation of freshly collected seep material under anoxic conditions with acetate-lactate or H(2) as an electron donor revealed the potential for rapid Fe(III) oxide reduction (ca. 700 to 2,000 micromol liter(-1) day(-1)). Fe(III) reduction at lower but significant rates took place in unamended controls (ca. 300 micromol liter(-1) day(-1)). Culture-based enumerations (most probable numbers [MPNs]) revealed significant numbers (10(2) to 10(6) cells ml(-1)) of organic carbon- and H(2)-oxidizing dissimilatory Fe(III)-reducing microorganisms. Three isolates with the ability to reduce Fe(III) oxides by dissimilatory or fermentative metabolism were obtained (Geobacter sp. strain IST-3, Shewanella sp. strain IST-21, and Bacillus sp. strain IST-38). MPN analysis also revealed the presence of microaerophilic Fe(II)-oxidizing microorganisms (10(3) to 10(5) cells ml(-1)). A 16S rRNA gene library from the iron seep was dominated by representatives of the Betaproteobacteria including Gallionella, Leptothrix, and Comamonas species. Aerobic Fe(II)-oxidizing Comamonas sp. strain IST-3 was isolated. The 16S rRNA gene sequence of this organism is 100% similar to the type strain of the betaproteobacterium Comamonas testosteroni (M11224). Testing of the type strain showed no Fe(II) oxidation. Collectively our results suggest that active microbial Fe redox cycling occurred within this habitat and support previous conceptual models for how microbial Fe oxidation and reduction can be coupled in surface and subsurface sedimentary environments.

    Industrial countries are faced with a growing elderly population. Homecare systems with assistive smart house technology enable elderly to live independently at home. Development of such smart home care systems is complex and expensive and there is no common reference model that can facilitate service reuse. This paper proposes reusable actor and service models based on a model-driven development process where end user organizations and domain healthcare experts from four European countries have been involved. The models, specified using UML can be reused actively as assets in the system design and development process and can reduce development costs, and improve interoperability and sustainability of systems. The models are being evaluated in the European IST project MPOWER.

  7. Wie verstehen Schülerinnen und Schüler den Begriff der Unendlichkeit?

    NASA Astrophysics Data System (ADS)

    Schimmöller, Tabea

    Wie Hilbert bereits feststellte, wirkt die Idee der Unendlichkeit, wie keine andere, schon seit Zeiten sehr anregend und fruchtbar auf den Verstand und bewegt das Gemüt der Menschen. Der Begriff der Unendlichkeit bedarf aber auch, wie kein anderer, der Aufklärung, denn mit ihm eröffnet sich ein weites Feld, welches nicht nur aus vielen verschiedenen Definitionen besteht, sondern auch aus völlig unterschiedlichen Disziplinen. Physiker suchen immer dringender nach einer "Theorie für Alles" oder einer "Weltformel", Kosmologen beschäftigen sich unter anderem mit der Ewigkeit des Universums, Theologen interessiert eher die Unendlichkeit Gottes, Philosophen diskutieren unter anderem Grenzfragen zwischen Naturwissenschaft und Philosophie und die Mathematiker versuchen den Paradoxien des Unendlichen einen Sinn zu geben. Und so wird ersichtlich, dass nichts abstrakter ist als das Unendliche: Obwohl die Unendlichkeit für die unterschiedlichsten Wissenschaften von großer Bedeutung ist, "[ist] in der Wirklichkeit das Unendliche nirgends zu finden, [egal] was für Erfahrungen und Beobachtungen und welcherlei Wissenschaft wir auch heranziehen".

    High-resolution dual polarized micropulse lidar (MPL) observations have been used to investigate the diurnal evolution of atmospheric boundary layer (ABL) during winter (2008-2011) over Thiruvananthapuram (8.5°N, 77°E), a tropical coastal station located at southwest Peninsular India, adjoining the Arabian Sea. The lidar observations are compared with the boundary layer characteristics derived from concurrent balloon-borne radiosonde observations. This study shows that the mixed layer height over this coastal station generally increases from <300 m in the morning to 1500 m by the afternoon. Growth rate of the mixed layer height is rapid ( 350 m/hr) during 09-11 IST and slows down with time to <150 m/hr during 11-14 IST and <90 m/hr during 14-16 IST. Thermal internal boundary layer during the afternoon, caused by sea breeze circulation, extends up to 500 m altitude and is characterized by highly spherical aerosols, while a distinctly non-spherical aerosol layer appear above this altitude, in the return flow arising from the landmass.

    Inappropriate sinus tachycardia (IST) is a rare disorder amenable to catheter ablation when refractory to medical therapy. Radiofrequency (RF) catheter modification/ablation of the sinus node (SN) is the usual approach, although it can be complicated by right phrenic nerve paralysis. We describe a patient with IST, who had symptomatic recurrences despite previous acutely successful RF SN modifications, including the use of electroanatomical mapping/navigation system. We decided to try transvenous cryothermal modification of the SN. We used 2 min applications at -85 degrees C at sites of the earliest atrial activation guided by activation mapping during isoprenaline infusion. Every application was preceded by high output stimulation to reveal phrenic nerve proximity. During the last application, heart rate slowly and persistently fell below 85 bpm despite isoprenaline infusion, but right diaphragmatic paralysis developed. At 6 months follow-up, the patient was asymptomatic and the diaphragmatic paralysis had partially resolved. This is the first report, we believe, of successful SN modification for IST by endocardial cryoablation, although this case also demonstrates the considerable risk of right phrenic nerve paralysis even with this ablation energy.

    The endosomal sorting complexes required for transport (ESCRT) proteins mediate fundamental membrane remodeling events that require stabilizing negative membrane curvature. These include endosomal intralumenal vesicle formation, HIV budding, nuclear envelope closure, and cytokinetic abscission. ESCRT-III subunits perform key roles in these processes by changing conformation and polymerizing into membrane-remodeling filaments. Here, we report the 4 angstrom resolution cryogenic electron microscopy reconstruction of a one-start, double-stranded helical copolymer composed of two different human ESCRT-III subunits, charged multivesicular body protein 1B (CHMP1B) and increased sodium tolerance 1 (IST1). The inner strand comprises “open” CHMP1B subunits that interlock in an elaborate domain-swapped architecturemore » and is encircled by an outer strand of “closed” IST1 subunits. Unlike other ESCRT-III proteins, CHMP1B and IST1 polymers form external coats on positively curved membranes in vitro and in vivo. In conclusion, our analysis suggests how common ESCRT-III filament architectures could stabilize different degrees and directions of membrane curvature.« less

    Loos, Andreas

    Wer schon einmal Nudeln selbst gemacht hat, der weiß: Frische Pasta kann ganz schön pappen. Das ist ein Problem für die Nudelindustrie, denn es ist nicht leicht, mit unregelmäßigen und klebrigen Nudel-Klumpen 500-Gramm-Beutel genau zu füllen. Einige Hersteller verwenden daher "Teilmengenwaagen". Die besitzen bis zu hundert kleineWaagschalen, die über ein Förderband mit jeweils ungefähr 50 Gramm Nudel-Klumpen befüllt werden. Dann kommt Mathematik ins Spiel: Ein Computer wählt die zehn Waagschalen aus, deren Inhalt zusammen die 500 Gramm genau erreicht, und leert sie in einen Beutel aus.

  19. Numerical Inverse Scattering for the Toda Lattice

    Bilman, Deniz; Trogdon, Thomas

    2017-06-01

    We present a method to compute the inverse scattering transform (IST) for the famed Toda lattice by solving the associated Riemann-Hilbert (RH) problem numerically. Deformations for the RH problem are incorporated so that the IST can be evaluated in O(1) operations for arbitrary points in the ( n, t)-domain, including short- and long-time regimes. No time-stepping is required to compute the solution because ( n, t) appear as parameters in the associated RH problem. The solution of the Toda lattice is computed in long-time asymptotic regions where the asymptotics are not known rigorously.

  20. The United Nations programme on space applications: priority thematic areas

    NASA Astrophysics Data System (ADS)

    Haubold, H.

    The Third United Nations Conference on the Exploration and Peaceful Uses of Outer Space (UNISPACE III) was held in 1999 with efforts to identify world wide benefits of developing space science and technology, particularly in the developing nations. One of the main vehicles to implement recommendations of UNISPACE III is the United Nations Programme on Space Applications of the Office for Outer Space Affairs at UN Headquarters in Vienna. Following a process of prioritization by Member States, the Programme focus its activities on (i) knowledge-based themes as space law and basic space science, (ii) application-based themes as disaster management, natural resources management, environmental monitoring, tele-health, and (iii) enabling technologies such as remote sensing satellites, communications satellites, global navigation satellite systems, and small satellites. Current activities of the Programme will be reviewed. Further information available at http://www.oosa.unvienna.org/sapidx.html

    Development programmes in Sahelian Africa are beginning to use geographic information system (GIS) technology. One of the GIS and remote sensing programmes introduced to the region in the late 1980s was the use of seasonal vegetation maps made from satellite data to support grasshopper and locust control. Following serious outbreaks of these pests in 1987, the programme addressed a critical need, by national and international crop protection organizations, to monitor site-specific dynamic vegetation conditions associated with grasshopper and locust breeding. The primary products used in assessing vegetation conditions were vegetation index (greenness) image maps derived from National Oceanic and Atmospheric Administration satellite imagery. Vegetation index data were integrated in a GIS with digital cartographic data of individual Sahelian countries. These near-real-time image maps were used regularly in 10 countries for locating potential grasshopper and locust habitats. The programme to monitor vegetation conditions is currently being institutionalized in the Sahel.

    Comprehensive multidisciplinary pulmonary rehabilitation is vital in the management of chronic obstructive pulmonary disease (COPD) and is considered for any stage of the disease. Rehabilitation programmes are often centre-based and organised in groups. However, the distance from the patient's home to the centre and lack of transportation may hinder participation. Rehabilitation at home can improve access to care for patients regardless of disease severity. We had previously studied the technology usability and acceptability of a comprehensive home rehabilitation programme designed for patients with very severe COPD receiving long-term oxygen therapy. The acceptability of such comprehensive home programmes for those with less severe COPD, who may be less homebound, is not known. The aims of this feasibility study were to assess patient acceptability of the delivery mode and components of a comprehensive pulmonary rehabilitation programme for any stage of COPD, as well as the technology usability, patient outcomes and economic aspects. Ten participants with COPD in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade I-IV were enrolled in a 9-week home programme and divided into two rehabilitation groups, with five patients in each group. The programme included exercise training and self-management education in online groups of patients, and individual online consultations. The patients also kept a digital health diary. To assess the acceptability of the programme, the patients were interviewed after the intervention using a semi-structured interview guide. In addition the number of sessions attended was observed. The usability of the technology was assessed using interviews and the System Usability Scale questionnaire. The St George's Respiratory Questionnaire (SGRQ) was used to measure health-related quality of life. The mode of delivery and the components of the programme were well accepted by the patients. The programme provided an environment for learning from both healthcare professionals and peers, for asking questions and discussing disease-related issues and for group exercising. The patients considered that it facilitated health-enhancing behaviours and social interactions with a social group formed among the participants. Even participants who were potentially less homebound appreciated the home group and social aspects of the programme. The participants found the technology easy to learn and use. The acceptability and usability results were consistent with those in our previous study of patients with very severe COPD. Only the mean change in the SGRQ total score of -6.53 (CI 95 % -0.38 to -12.68, p = 0.04) indicates a probable clinically significant effect. Economic calculations indicated that the cost of the programme was feasible. The results of this study indicate that comprehensive pulmonary rehabilitation delivered in home-based online groups may be feasible in COPD. The mode of delivery and components of the programme appeared to be acceptable across patients with different disease severity. The results in terms of patient outcomes are inconclusive, and further assessment is needed.

    A field-programmable logic device (FPLD) with optical I/O is described. FPLD's with optical I/O can have their functionality specified in the field by means of downloading a control-bit stream and can be used in a wide range of applications, such as optical signal processing, optical image processing, and optical interconnects. Our device implements six state-of-the-art dynamically programmable logic arrays (PLA's) on a 2 mm x 2 mm die. The devices were fabricated through the Lucent Technologies-Advanced Research Projects Agency-Consortium for Optical and Optoelectronic Technologies in Computing (Lucent/ARPA/COOP) workshop by use of 0.5-microm complementary metal-oxide semiconductor-self-electro-optic device technology and were delivered in 1998. All devices are fully functional: The electronic data paths have been verified at 200 MHz, and optical tests are pending. The device has been programmed to implement a two-stage optical switching network with six 4 x 4 crossbar switches, which can realize more than 190 x 10(6) unique programmable input-output permutations. The same device scaled to a 2 cm x 2 cm substrate could support as many as 4000 optical I/O and 1 Tbit/s of optical I/O bandwidth and offer fully programmable digital functionality with approximately 110,000 programmable logic gates. The proposed optoelectronic FPLD is also ideally suited to realizing dense, statically reconfigurable crossbar switches. We describe an attractive application area for such devices: a rearrangeable three-stage optical switch for a wide-area-network backbone, switching 1000 traffic streams at the OC-48 data rate and supporting several terabits of traffic.

    Research on nuclear technologies has been largely driven by a detachment of the 'technical content' from the 'social context'. However, social studies of science and technology--also for the nuclear domain--emphasize that 'the social' and 'the technical' dimensions of technology development are inter-related and co-produced. In an effort to create links between nuclear research and innovation and society in mutually beneficial ways, the Belgian Nuclear Research Centre started fifteen years ago a 'Programme of Integration of Social Aspects into nuclear research' (PISA). In line with broader science-policy agendas (responsible research and innovation and technology assessment), this paper argues that the importance of such programmes is threefold. First, their multi-disciplinary basis and participatory character contribute to a better understanding of the interactions between science, technology and society, in general, and the complexity of nuclear technology assessment in particular. Second, their functioning as (self -)critical policy supportive research with outreach to society is an essential prerequisite for policies aiming at generating societal trust in the context of controversial issues related to nuclear technologies and exposure to ionising radiation. Third, such programmes create an enriching dynamic in the organisation itself, stimulating collective learning and transdisciplinarity. The paper illustrates with concrete examples these claims and concludes by discussing some key challenges that researchers face while engaging in work of this kind. Copyright © 2015 Elsevier Ltd.

    Although trials continue to emerge supporting the role of telerehabilitation, implementation has been slow. Key users include older people living with disabilities who are frequent users of hospital rehabilitation services but whose voices are rarely heard. It is unclear whether the use of technologies and reduced face-to-face contact is acceptable to these people. We report on a qualitative study of community dwelling participants who had received a home telerehabilitation programme as an alternative to conventional rehabilitation. Thirteen older participants, three spouses and one carer were interviewed. All had participated in an individualized therapy programme, using a combination of face-to-face and video consults with therapists. The programme used 'off-the-shelf' technologies including iPads for videoconferencing and electronic FitBit R devices. Interviews were recorded, transcribed verbatim and analysed using NVivo software. Thematic analysis resulted in five emergent themes: (i) telerehabilitation is convenient; (ii) telerehabilitation promotes motivation and self-awareness; (iii) telerehabilitation fosters positive therapeutic relationships; (iv) mastering technologies used by younger relatives is a valued aspect of telerehabilitation; and (v) Telerehabilitation does not replace traditional face-to-face rehabilitation therapies. Participants found telerehabilitation convenient and motivating, coped well with the technology and developed positive therapeutic relationships. The learning and practice aspects sat well in the context of a rehabilitation programme. The use of commercially available technologies may have contributed to respondents' high levels of acceptability. The perception of telerehabilitation as complementary to in-person care and the expectation of technological support have implications for the implementation and delivery of telerehabilitation services to older people. © 2016 The Authors.

    Male infertility is a multifactorial disorder with impressively genetic basis; besides, sperm abnormalities are the cause of numerous cases of male infertility. In this study, we evaluated the genetic variants in exons 4 and 5 and their intron-exon boundaries in RABL2B gene in infertile men with oligoasthenoteratozoospermia (OAT) and immotile short tail sperm (ISTS) defects to define if there is any association between these variants and human male infertility. To this purpose, DNA was extracted from peripheral blood and after PCR reaction and sequencing, the results of sequenced segments were analyzed. In the present study, 30 infertile men with ISTS defect and 30 oligoasthenoteratozoospermic infertile men were recruited. All men were of Iranian origin and it took 3 years to collect patient's samples with ISTS defect. As a result, the 50776482 delC intronic variant (rs144944885) was identified in five patients with oligoasthenoteratozoospermia defect and one patient with ISTS defect in heterozygote form. This variant was not identified in controls. The allelic frequency of the 50776482 delC variant was significantly statistically higher in oligoasthenoteratozoospermic infertile men (p < 0.05). Bioinformatics studies suggested that the 50776482 delC allele would modify the splicing of RABL2B pre-mRNA. In addition, we identified a new genetic variant in RABL2B gene. According to the present study, 50776482 delC allele in the RABL2B gene could be a risk factor in Iranian infertile men with oligoasthenoteratozoospermia defect, but more genetic studies are required to understand the accurate role of this variant in pathogenesis of human male infertility.

    Antithymocyte globulins (ATG) plus cyclosporine (CSA) is the gold standard immunosuppressive treatment (IST) for patients with aplastic anemia. A prospective randomized trial showed in 2011 that hATG was superior to rabbit ATG for first-line treatment of severe AA. The French Health Agency (ANSM) permitted a patient-named authorization for temporary use (ATU) program of hATG (ATGAM, Pfizer) in patients with AA in 2011 since commercial access to hATG is not approved. We took advantage of this program to analyze the outcomes of 465 patients who received antithymocyte globulins (ATGAM) plus CSA as first line treatment (n = 379; 81.5%), or for refractory (n = 26) or relapsed disease (n = 33), from September 2011 to March 2017. In the entire cohort one year, 72% of the patients had partial and 13% had complete response, with worse response for patients with severe AA and a longer interval between diagnosis and IST (more than 6 months). Severe adverse events were mainly linked to infections (24%), hemorrhages (6%), and elevated liver function tests (5%). Overall at 12 months, 9.7% of patients required second line IST and 15.6% received transplantation. Fifty-five patients died during the study mainly because of infections (53%). Factors predicting independently worse survival were age over 40 years, neutrophils less than 0.5 × 10 9 /L, male gender and longer delay between diagnosis and hATG (>6 months period). This study does illustrate the results of ATGAM with CSA in a true-life perspective and confirms ATGAM as standard of care IST to treat patients with AA not eligible for HSCT. © 2018 Wiley Periodicals, Inc.

  12. Antiproliferative activity and interactions with cell-cycle related proteins of the organotin compound triethyltin(IV)lupinylsulfide hydrochloride.

    Organotin compounds, particularly tri-organotin, have demonstrated cytotoxic properties against a number of tumor cell lines. On this basis, triethyltin(IV)lupinylsulfide hydrochloride (IST-FS 29), a quinolizidine derivative, was synthesized and developed as a potential antitumor agent. This tin-derived compound exhibited potent antiproliferative effects on three different human cancer cell lines: teratocarcinoma of the ovary (PA-1), colon carcinoma (HCT-8) and glioblastoma (A-172). Cytotoxic activity was assessed by MTT and cell count assays during time course experiments with cell recovery after compound withdrawal. Significant cell growth inhibition (up to 95% in HCT-8 after 72 h of exposure), which also persisted after drug-free medium change, was reported in all the cell lines by both assays. In addition, the cytocidal effects exerted by IST-FS 29 appeared more consistent with necrosis or delayed cell death, rather than apoptosis, as shown by morphologic observations under light microscope, DNA fragmentation analysis and flow cytometry. In the attempt to elucidate whether this compound might affect genes playing a role in G1/S phase transition, the expressions of p53, p21(WAF1), cyclin D1 and Rb, mainly involved in response to DNA-damaging stress, were analyzed by Western blot. Heterogeneous patterns of expression during exposure to IST-FS 29 were evidenced in the different cell lines suggesting that these cell-cycle-related genes are not likely the primary targets of this compound. Thus, the present data seem more indicative of a direct effect of IST-FS-29 on macromolecular synthesis and cellular homeostasis, as previously hypothesized for other organotin complexes.

  13. A Climate-Data Record (CDR) of the "Clear Sky" Surface Temperature of the Greenland Ice Sheet

    Hall, Dorothy K.; Comiso, J. C.; DiGirolamo, N. E.; Shuman, C. A.

    2011-01-01

    To quantify the ice-surface temperature (IST) we are developing a climate-data record (CDR) of monthly IST of the Greenland ice sheet, from 1982 to the present using Advanced Very High Resolution Radiometer (AVHRR) and Moderate-Resolution Imaging Spectroradiometer (MODIS) data at 5-km resolution. "Clear-sky" surface temperature increases have been measured from the early 1980s to the early 2000s in the Arctic using AVHRR data, showing increases ranging from 0.57-0.02 (Wang and Key, 2005) to 0.72 0.10 deg C per decade (Comiso, 2006). Arctic warming has implications for ice-sheet mass balance because much of the periphery of the ice sheet is near 0 deg C in the melt season and is thus vulnerable to more extensive melting (Hanna et al., 2008). The algorithm used for this work has a long history of measuring IST in the Arctic with AVHRR (Key and Haefliger, 1992). The data are currently available from 1981 to 2004 in the AVHRR Polar Pathfinder (APP) dataset (Fowler et al., 2000). J. Key1NOAA modified the AVHRR algorithm for use with MODIS (Hall et al., 2004). The MODIS algorithm is now being processed over Greenland. Issues being addressed in the production of the CDR are: time-series bias caused by cloud cover, and cross-calibration between AVHRR and MODIS instruments. Because of uncertainties, time series of satellite ISTs do not necessarily correspond with actual surface temperatures. The CDR will be validated by comparing results with in-situ (see Koenig and Hall, in press) and automatic-weather station data (e.g., Shuman et al., 2001).

    Our contribution, drawn from our experience of the case study provided, is a protocol for practice-centred, participative evaluation of technology in the clinical setting that privileges care. In this context 'practice-centred' evaluation acts as a scalable, coordinating framework for evaluation that recognises health information technology supported care as an achievement that is contingent and ongoing. We argue that if complex programmes of technology-enabled service innovation are understood in terms of their contribution to patient care and supported by participative, capability-building evaluation methodologies, conditions are created for practitioners and patients to realise the potential of technologies and make substantive contributions to the evidence base underpinning health innovation programmes. Electronic Patient Records (EPRs) and telemedicine are positioned by policymakers as health information technologies that are integral to achieving improved clinical outcomes and efficiency savings. However, evaluating the extent to which these aims are met poses distinct evaluation challenges, particularly where clinical and cost outcomes form the sole focus of evaluation design. We propose that a practice-centred approach to evaluation - in which those whose day-to-day care practice is altered (or not) by the introduction of new technologies are placed at the centre of evaluation efforts - can complement and in some instances offer advantages over, outcome-centric evaluation models. We carried out a regional programme of innovation in renal services where a participative approach was taken to the introduction of new technologies, including: a regional EPR system and a system to support video clinics. An 'action learning' approach was taken to procurement, pre-implementation planning, implementation, ongoing development and evaluation. Participants included clinicians, technology specialists, patients and external academic researchers. Whilst undergoing these activities we asked: how can a practice-centred approach be embedded into evaluation of health information technologies? Organising EPR and telemedicine evaluation around predetermined outcome measures alone can be impractical given the complex and contingent nature of such projects. It also limits the extent to which unforeseen outcomes and new capabilities are recognised. Such evaluations often fail to improve understanding of 'when' and 'under what conditions' technology-enabled service improvements are realised, and crucially, how such innovation improves care. Our contribution, drawn from our experience of the case study provided, is a protocol for practice-centred, participative evaluation of technology in the clinical setting that privileges care. In this context 'practice-centred' evaluation acts as a scalable, coordinating framework for evaluation that recognises health information technology supported care as an achievement that is contingent and ongoing. We argue that if complex programmes of technology-enabled service innovation are understood in terms of their contribution to patient care and supported by participative, capability-building evaluation methodologies, conditions are created for practitioners and patients to realise the potential of technologies and make substantive contributions to the evidence base underpinning health innovation programmes.

    With the recognition of the need for research capacity strengthening for advancing health and development, this research capacity article explores the use of technology enhanced learning in the delivery of a collaborative postgraduate blended Master's degree in Malawi. Two research questions are addressed: (i) Can technology enhanced learning be used to develop health research capacity?, and: (ii) How can learning content be designed that is transferrable across different contexts? An explanatory sequential mixed methods design was adopted for the evaluation of technology enhanced learning in the Masters programme. A number of online surveys were administered, student participation in online activities monitored and an independent evaluation of the programme conducted. Remote collaboration and engagement are paramount in the design of a blended learning programme and support was needed for selecting the most appropriate technical tools. Internet access proved problematic despite developing the content around low bandwidth availability and training was required for students and teachers/trainers on the tools used. Varying degrees of engagement with the tools used was recorded, and the support of a learning technologist was needed to navigate through challenges faced. Capacity can be built in health research through blended learning programmes. In relation to transferability, the support required institutionally for technology enhanced learning needs to be conceptualised differently from support for face-to-face teaching. Additionally, differences in pedagogical approaches and styles between institutions, as well as existing social norms and values around communication, need to be embedded in the content development if the material is to be used beyond the pilot resource-intensive phase of a project.

  18. Strategic considerations in Indian space programme—Towards maximising socio-economic benefits

    2008-07-01

    Strategic thinking and planning have been the hallmarks of Indian space programme, whose objectives are sharply focused on deriving socio-economic benefits of space technology. The purpose of this paper is to identify various strategies, which played a role in different phases of the programme, contributing to social and economic outcomes and effectiveness. While self-reliant development of technological capacity and evaluation of applications with involvement of users formed the backbone of strategy in the initial phase of the programme, subsequent strategies were centred on development of organisational culture and systems, industry role and promotion of spin offs. Other strategies dealt with the response to challenges inherent in space endeavours in terms of risk management, sustainability, investments and long-term commitments, judicious make or buy decisions, safeguard of sensitive technologies, space commerce and finally harmonising international cooperation with national objectives. The strategies in the programme were consistently driven by a clear-cut vision and objectives to develop and use space technology in diverse areas where space systems become relevant for socio-economic development such as telecommunications and broadcasting, meteorology, disaster management support, remote sensing of natural and anthropogenic phenomena, and positioning and navigation services. This paper synthesises various studies and experiences in India in order to analyse strategies in the face of changes in technology, application needs and international policies. It also examines the effectiveness of these strategies in terms of economic and social costs and benefits. Based on the above analysis, a typical conceptual model for use of space for development is suggested.

    The PEI Programme in the WHO African region invested in recruitment of qualified staff in data management, developing data management system and standards operating systems since the revamp of the Polio Eradication Initiative in 1997 to cater for data management support needs in the Region. This support went beyond polio and was expanded to routine immunization and integrated surveillance of priority diseases. But the impact of the polio data management support to other programmes such as routine immunization and disease surveillance has not yet been fully documented. This is what this article seeks to demonstrate. We reviewed how Polio data management area of work evolved progressively along with the expansion of the data management team capacity and the evolution of the data management systems from initiation of the AFP case-based to routine immunization, other case based disease surveillance and Supplementary immunization activities. IDSR has improved the data availability with support from IST Polio funded data managers who were collecting them from countries. The data management system developed by the polio team was used by countries to record information related to not only polio SIAs but also for other interventions. From the time when routine immunization data started to be part of polio data management team responsibility, the number of reports received went from around 4000 the first year (2005) to >30,000 the second year and to >47,000 in 2014. Polio data management has helped to improve the overall VPD, IDSR and routine data management as well as emergency response in the Region. As we approach the polio end game, the African Region would benefit in using the already set infrastructure for other public health initiative in the Region. Copyright © 2016 The Authors.

    The Dragon Programme is a joint undertaking between ESA and the Ministry of Science and Technology (MOST) of China and the National Remote Sensing Center of China (NRSCC). Its purpose is to encourage increased exploitation of ESA and Chinese space resources within China as well as stimulate increased scientific cooperation in the field of Earth Observation (EO) science and applications between China and Europe. Since 2004, this pioneering programme has become a model for scientific and technological cooperation between China and Europe. By successfully encouraging joint research using ESA, Third Party Missions and Chinese EO data across a range of thematic areas, Dragon continues to deliver outstanding scientific results. The programme has successfully completed two phases, Dragon 1 from 2004 to 2008, Dragon 2 from 2008 to 2012. The third phase of Dragon was started in 2012 and will be completed in 2016. The Dragon 3 project teams are led by leading EO scientists and young scientists are also engaged on the projects. Advanced training in land, ocean and atmospheric applications is a feature of the programme and a course on land and one course on ocean applications have been successfully held in 2012 and 2013 in China. Here-in provided is an overview of the results, reporting and training activities at the mid-term stage of the programme.

  4. Strahlungsfeldbedingungen bei der Ionisationsdosimetrie

    Krieger, Hanno

    Bei der Dosimetrie von Photonenstrahlungen mit luftgefüllten Ionisationskammern werden in diesem Kapitel zwei Grenzfälle unterschieden. Der eine Fall ist die Bedingung des so genannten Sekundärelektronengleichwichts im Kammervolumen. In diesem Fall bestimmen ausschließlich die Photonen im Messvolumen die dosimetrische Anzeige. Der zweite Grenzfall ist gegeben, wenn das Luftvolumen und die Kammer das Strahlungsfeld im Phantom so wenig stören, dass der Sekundärelektronenfluss unverändert bleibt. Diese Bedingungen nennt man BRAGG-GRAY-Bedingungen. Beide Grenzfälle sind in der Praxis nur näherungsweise zu verwirklichen. Abweichungen müssen durch entsprechende Korrekturen oder Kalibrierungen berücksichtigt werden.

    Die Entscheidung, einen zeit- bzw. ereignisgesteuerten Ansatz für ein Echtzeitsystem zu verwenden, ist schwierig und sehr weitreichend. Weitreichend vor allem deshalb, weil diese beiden Ansätze mit äußerst unterschiedlichen Kontrollflussabstraktionen verknüpft sind, die eine spätere Migration zum anderen Paradigma sehr schwer oder gar unmöglich machen. Wir schlagen daher die Verwendung einer Zwischendarstellung vor, die unabhängig von der jeweils verwendeten Kontrollflussabstraktion ist. Für diesen Zweck verwenden wir auf Basisblöcken basierende Atomic Basic Blocks (ABB) und bauen darauf ein Werkzeug, den Real-Time Systems Compiler (RTSC) auf, der die Migration zwischen zeit- und ereignisgesteuerten Systemen unterstützt.

    Basic vacuum calculations were performed for various operating conditions of the Los Alamos National Neutron Science H(-) Cockcroft-Walton (CW) injector and the Ion Source Test Stand (ISTS). The vacuum pressure was estimated for both the CW and ISTS at five different points: (1) inside the H(-) ion source, (2) in front of the Pierce electrode, (3) at the extraction electrode, (4) at the column electrode, and (5) at the ground electrode. A static vacuum analysis of residual gases and the working hydrogen gas was completed for the normal ion source working regime. Gas density and partial pressure were estimated for the injected hydrogen gas. The attenuation of H(-) beam current and generation of electron current in the high voltage acceleration columns and low energy beam transport lines were calculated. The interaction of H(-) ions on molecular hydrogen (H2) is discussed as a dominant collision process in describing electron stripping rates. These results are used to estimate the observed increase in the ratio of electrons to H(-) ion beam in the ISTS beam transport line.

    Enhanced melting along with surface-temperature increases measured using infrared satellite data, have been documented for the Greenland Ice Sheet. Recently we developed a climate-quality data record of ice-surface temperature (IST) of the Greenland Ice Sheet using the Moderate-Resolution Imaging Spectroradiometer (MODIS) 1ST product -- http://modis-snow-ice.gsfc.nasa.gov. Using daily and mean monthly MODIS 1ST maps from the data record we show maximum extent of melt for the ice sheet and its six major drainage basins for a 12-year period extending from March of 2000 through December of 2011. The duration of the melt season on the ice sheet varies in different drainage basins with some basins melting progressively earlier over the study period. Some (but not all) of the basins also show a progressively-longer duration of melt. The short time of the study period (approximately 12 years) precludes an evaluation of statistically-significant trends. However the dataset provides valuable information on natural variability of IST, and on the ability of the MODIS instrument to capture changes in IST and melt conditions indifferent drainage basins of the ice sheet.

    Bacterial survival strategies involve phenotypic diversity which is generated by regulatory factors and noisy expression of effector proteins. The question of how bacteria exploit regulatory RNAs to make decisions between phenotypes is central to a general understanding of these universal regulators. We investigated the TisB/IstR-1 toxin-antitoxin system of Escherichia coli to appreciate the role of the RNA antitoxin IstR-1 in TisB-dependent depolarization of the inner membrane and persister formation. Persisters are phenotypic variants that have become transiently drug-tolerant by arresting growth. The RNA antitoxin IstR-1 sets a threshold for TisB-dependent depolarization under DNA-damaging conditions, resulting in two sub-populations: polarized and depolarized cells. Furthermore, our data indicate that an inhibitory 5' UTR structure in the tisB mRNA serves as a regulatory RNA element that delays TisB translation to avoid inappropriate depolarization when DNA damage is low. Investigation of the persister sub-population further revealed that both regulatory RNA elements affect persister levels as well as persistence time. This work provides an intriguing example of how bacteria exploit regulatory RNAs to control phenotypic heterogeneity. © 2016 John Wiley & Sons Ltd.

  10. Validation of a Climate-Data Record of the "Clear-Kky" Surface Temperature of the Greenland Ice Sheet

    Surface temperatures on the Greenland Ice Sheet have been studied on the ground, using automatic weather station (AWS) data from the Greenland-Climate Network (GC-Net), and from analysis of satellite sensor data. Using Advanced Very High Frequency Radiometer (AVHRR) weekly surface temperature maps, warming of the surface of the Greenland Ice Sheet has been documented since 1981. We extended and refined this record using higher-resolution Moderate-Resolution Imaging Spectroradiometer (MODIS) data from March 2000 to the present. We developed a daily and monthly climate-data record (CDR) of the "clear-sky" surface temperature of the Greenland Ice Sheet using an ice-surface temperature (1ST) algorithm developed for use with MODIS data. Validation of this CDR is ongoing. MODIS Terra swath data are projected onto a polar stereographic grid at 6.25-km resolution to develop binary, gridded daily and mean-monthly 1ST maps. Each monthly map also has a color-coded image map that is available to download. Also included with the monthly maps is an accompanying map showing number of days in the month that were used to calculate the mean-monthly 1ST. This is important because no 1ST decision is made by the algorithm for cells that are considered cloudy by the internal cloud mask, so a sufficient number of days must be available to produce a mean 1ST for each grid cell. Validation of the CDR consists of several facets: 1) comparisons between ISTs and in-situ measurements; 2) comparisons between ISTs and AWS data; and 3) comparisons of ISTs with surface temperatures derived from other satellite instruments such as the Thermal Emission and Reflection Radiometer (ASTER) and Enhanced Thematic Mapper Plus (ETM+). Previous work shows that Terra MODIS ISTs are about 3 C lower than in-situ temperatures measured at Summit Camp, during the winter of 2008-09 under clear skies. In this work we begin to compare surface temperatures derived from AWS data with ISTs from the MODIS CDR. The Greenland Ice Sheet 1ST CDR will be useful for monitoring surface-temperature trends and can be used as input or for validation of climate models. The CDR can be extended into the future using MODIS Terra, Aqua and NPOESS Preparatory Project Visible Infrared Imager Radiometer Suite (VII RS) data.

    Over past four decades Indian space programme has systematically acquired capabilities in space technologies and implemented its programmes with a high level of focus on societal applications. It is developed into a multi-dimensional programme where its strategy is directed towards diverse stake holders and actors such as government, users and beneficiaries including general public, industrial suppliers as well as customers, academia and other space agencies/international organisations. Over the next five years, the Indian space programme has charted an ambitious set of policies and programmes that aim to enhance impacts on society. The major task is to enlarge and diversify the services delivered to a large section of population affected by income, connectivity and digital divides. While efficacy of application of space based systems have been proven in several fields such as tele-education, water resources management, improving productivity of land and out reaching quality health services and others, the crux of the problem is to evolve sustainable and scalable delivery mechanisms on a very large scale and extending over large geographical areas. Essentially the problem shifts from being predominately a technology problem to one of a composite of economic, cultural and social problems. Tackling such problems would need renewal of policies relating to commercial as well as public service systems. Major programmatic initiatives are planned in the next five years involving new and upgraded technologies to expand services from space to fill the gaps and to improve economic efficiency. Thrust is also given to science and exploration mission beyond Chandrayaan-1 and some initial steps for the participation in human space flight. This paper discusses the policy and strategy perspectives of the programmes planned by Indian Space Research Organisation over next five years.

  13. Exploring physical activity behaviour - needs for and interest in a technology-delivered, home-based exercise programme among patients with intermittent claudication.

    Supervised walking is a first line therapy in peripheral arterial disease (PAD) with complaints of intermittent claudication. However, uptake of supervised programmes is low. Home-based exercise seems an appealing alternative; especially since technological advances, such as tele-coaching and tele-monitoring, may facilitate the process and support patients when adopting a physically active lifestyle. To guide the development of such an intervention, it is important to identify barriers of physical activity and the needs and interests for technology-enabled exercise in this patient group. PAD patients were recruited at the vascular centre of UZ Leuven (Belgium). A questionnaire assessing PA (SF-International Physical Activity Questionnaire), barriers to PA, and interest in technology-supported exercise (Technology Usage Questionnaire) was completed. Descriptive and correlation analyses were performed. Ninety-nine patients (76 men; mean age 69 years) completed the survey. Physical activity levels were low in 48 %, moderate in 29 %, and high in 23 %. Intermittent claudication itself is the most important barrier for enhanced PA, with most patients reporting pain (93 %), need for rest (92 %), and obstacles worsening their pain (74 %) as barriers. A total of 93 % participants owned a mobile phone; 76 % had Internet access. Eighty-seven reported the need for an exercise programme, with 67 % showing interest in tele-coaching to support exercise. If technology was available, three-quarter stated they would be interested in home-based tele-coaching using the Internet (preferably e-mails, 86 %); 50 % via mobile phone, 87 % preferred text messages. Both were inversely related to age (rpb = 0.363 and rpb = 0.255, p < 0.05). Acquaintance with elastic bands or gaming platforms was moderate (55 and 49 %, respectively), but patients were interested in using them as alternatives (84 and 42 %). Interest in platforms was age-dependent (rs = -0.508, p < 0.01). PAD patients show significant interest in technology-delivered exercise, offering opportunities to develop a guided home-based exercise programme.

    Monitoring and empirical evaluation are essential components of evidence based public health policies and programmes. Consequently, there is a growing interest in monitoring of, and indicators for, major environmental health risks, particularly in the developing world. Current large scale data collection efforts are generally disconnected from micro-scale studies in health sciences, which in turn have insufficiently investigated the behavioural and socioeconomic factors that influence exposure. A basic framework is proposed for development of indicators of exposure to environmental health risks that would facilitate the (a) assessment of the health effects of risk factors, (b) design and evaluation of interventions and programmes to deliver the interventions, and (c) appraisal and quantification of inequalities in health effects of risk factors, and benefits of intervention programmes and policies. Specific emphasis is put on the features of environmental risks that should guide the choice of indicators, in particular the interactions of technology, the environment, and human behaviour in determining exposure. The indicators are divided into four categories: (a) access and infrastructure, (b) technology, (c) agents and vectors, and (d) behaviour. The study used water and sanitation, indoor air pollution from solid fuels, urban ambient air pollution, and malaria as illustrative examples for this framework. Organised and systematic indicator selection and monitoring can provide an evidence base for design and implementation of more effective and equitable technological interventions, delivery programmes, and policies for environmental health risks in resource poor settings.

    To describe progress and perceived challenges in implementing the NHS information and technology (IT) programme in England. Case studies and in-depth interviews, with themes identified using a framework developed from grounded theory. We interviewed personnel who had been interviewed 18 months earlier, or new personnel in the same posts. Four NHS acute hospital trusts in England. Senior trust managers and clinicians, including chief executives, directors of IT, medical directors, and directors of nursing. Interviewees unreservedly supported the goals of the programme but had several serious concerns. As before, implementation is hampered by local financial deficits, delays in implementing patient administration systems that are compliant with the programme, and poor communication between Connecting for Health (the agency responsible for the programme) and local managers. New issues were raised. Local managers cannot prioritise implementing the programme because of competing financial priorities and uncertainties about the programme. They perceive a growing risk to patients' safety associated with delays and a loss of integration of components of the programme, and are discontented with Choose and Book (electronic booking for referrals from primary care). We recommend that the programme sets realistic timetables for individual trusts and advises managers about interim IT systems they have to purchase because of delays outside their control. Advice needs to be mindful of the need for trusts to ensure longer term compatibility with the programme and value for money. Trusts need assistance in prioritising modernisation of IT by, for example, including implementation of the programme in the performance management framework. Even with Connecting for Health adopting a different approach of setting central standards with local implementation, these issues will still need to be addressed. Lessons learnt in the NHS have wider relevance as healthcare systems, such as in France and Australia, look to realise the potential of large scale IT modernisation.

    2014-01-01

    All governments face immense challenges in providing affordable healthcare for their citizens, and the diffusion of novel health technologies is a key driver of growth in expenditure for many. Although important methodological and process variations exist around the world, health economic evaluation is increasingly seen as an important tool to support decision-making around the introduction of new health technologies, interventions and programmes in countries of varying stages of economic development. In Australia, the assessment of the comparative cost-effectiveness of new medicines proposed for subsidy under the country's national drug subsidy programme, the Pharmaceutical Benefits Scheme, was introduced in the late 1980s and became mandatory in 1993, making Australia the first country to introduce such a requirement nationally. Since then the use of health economic evaluation has expanded and been applied to support decision-making across a broader range of health technologies, as well as to programmes in public health.

    2014-01-01

    Several studies have documented the health-related benefits of older adults' use of computer technology, but before they can be realised, older individuals must be positively inclined and confident in their ability to engage in computer-based environments. To facilitate the assessment of computer technology attitudes, one aim of the longitudinal study reported in this paper was to test and refine a new 22-item measure of computer technology attitudes designed specifically for older adults, as none such were available.1 Another aim was to replicate, on a much larger scale, the successful findings of a preliminary study that tested a computer technology training programme for older adults (Laganà 2008). Ninety-six older men and women, mainly from non-European-American backgrounds, were randomly assigned to the waitlist/control or the experimental group. The same six-week one-on-one training was administered to the control subjects at the completion of their post-test. The revised (17-item) version of the Older Adults' Computer Technology Attitudes Scale (OACTAS) showed strong reliability: the results of a factor analysis were robust, and two analyses of covariance demonstrated that the training programme induced significant changes in attitudes and self-efficacy. Such results encourage the recruitment of older persons into training programmes aimed at increasing computer technology attitudes and self-efficacy. PMID:25512679

    The aim of this study was to determine the histomorphological changes that occurred in response to two treatments for oestrus synchronization in three different regions of the gilt's uterine tubes epithelium: the ampulla (AMP), ampulla-isthmic junction (AIJ) and isthmus (IST). Nine prepuberal gilts were divided into three groups (n = 3): (1) eCG 400 IU and hCG 200 IU (eCG/hCG), (2) progesterone agonist (P4) and (3) control group. The number of secretory cells (stained with periodic acid-Schiff reaction or PAS-positive cells) decreased in the AMP in the P4 treated group when compared to the control group, whereas, no difference was observed in the number of PAS-negative cells in the AMP of the three groups. A significant decrease in the number of PAS-positive cells was observed in the AIJ and IST of the P4 treated group when compared to the eCG/hCG and control groups. An increase in the number of PAS-negative cells was observed in the AIJ and IST in the P4 treated group. The epithelium height in the AMP and AIJ was increased in the eCG/hCG group when compared to the control and P4 groups. In this last group, we observed a reduced height compared with the other two groups for the AIJ. In the IST, there were no significant changes in the epithelium height of the control or the other two groups (eCG/hCG and P4). The epithelial cells of the P4 treated group had the least amount of cytoplasmic granules and the lowest intensity of PAS staining in the AMP, AIJ and IST. Animals treated with eCG/hCG showed an intermediate number of cytoplasmic granules and intensity in all regions evaluated. These data show that P4 treatment for synchronization induces a significant (P < 0.001) decrease of PAS-positive cells and staining intensity of cytoplasmic granules in the different regions studied and an increased number of PAS-negative cells in the AIJ and IST epithelium. Moreover, eCG/hCG treatment increased the height of the epithelium in the AMP and AIJ, while in this last region, the P4 treatment decreased the epithelium height. These results show that synchronization treatments with P4 and in a smaller proportion with eCG/hCG can modify the amount of PAS-positive and PAS-negative cells, and the epithelium height. This has influence in the secretory activity of the epithelium and possibly alters the fluid microenvironment of the gilt's uterine tube. The biological impact of regional variations in the epithelial cells of the gilt's uterine tube needs further investigation to understand the implications that the reproductive processes can have in the uterine tube. © 2014 Blackwell Verlag GmbH.

    1992-12-01

    The National Statement on Technology Education will soon be released in Australia. The statement advocates a design, make and appraise approach to technology education. The document includes Year One children and provides exemplars of curriculum activities for early childhood children. Although much curriculum development in technology education for primary and early childhood has taken place in the UK, little research has been conducted within the early childhood area in Australia. This paper describes a study which sought to investigate how the design, make and appraise approach could be implemented within early childhood using existing materials, procedures and teaching programmes. In particular, the pre-school programme was considered to see if the approach was suitable for young children, and if girls could be encouraged into this newly defined area of study.

    This paper describes students' experiences of a Web-based innovation at one university. This paper reports on the first phase of this development where two Web-based modules were developed. Using a survey approach (n=44) students' access to and use of computer technology were explored. Findings revealed that students' prior use of computers and Internet technologies was higher than previously reported, although use of databases was low. Skills in this area increased during the programme, with a significant rise in database, email, search engine and word processing use. Many specific computer skills were learned during the programme, with high numbers reporting ability to deal adequately with files and folders. Overall, the experience was a positive one for students. While a sense of student isolation was not reported, as many students kept in touch by phone and class attendance continued, some individual students did appear to isolate themselves. This teaching methodology has much to offer in the provision of convenient easy to access programmes that can be easily adapted to the individual lifestyle. However, student support mechanisms need careful consideration for students who are at risk of becoming isolated. Staff also need to supported in the provision of this methodology and face-to-face contact with teachers for some part of the programme is preferable.

    Thus far seven Concentrated Solar Power (CSP) projects have been awarded under the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP), totalling 600MW: one project is in operation, four under construction and two on their way to financial close. This provides an excellent opportunity for analysis of key features of the projects that have contributed to or detracted from the programme's success. The paper draws from Mott MacDonald's involvement as Technical Advisor on the seven CSP projects that have been successful under the REIPPPP to date as well as other global CSP developments. It presents how various programme requirements have affected the implementation of projects, such as the technical requirements, time of day tariff structure, economic development requirements and the renewable energy grid code. The increasingly competitive tariffs offered have encouraged developers to investigate efficiency maximising project configurations and cost saving mechanisms, as well as featuring state of the art technology in their proposals. The paper assesses the role of the project participants (developers, lenders and government) with regards to these innovative technologies and solutions. In our paper we discuss the status of projects and the SA market, analysing the main challenges and opportunities that in turn have influenced various aspects such as technology choice, operational regimes and supply chain arrangements.

    We examined the feasibility of and parental satisfaction with a training programme for parents with children who had suffered traumatic brain injury (TBI). Families who did not have a home computer and/or webcam were loaned the necessary equipment. Skype was used for videoconferencing. After the initial treatment session in the family's home, the remaining nine sessions were conducted online. Each session had two parts: (1) a self-guided web session with information about a particular skill; (2) a videoconference session with the therapist. Three of the 20 families (15%) dropped out prior to the final 6-month follow-up visit. Of the remaining 17 families, 13 (65% of those enrolled) completed 9-14 sessions. Almost all of the caregivers (87%) said that the Skype sessions were helpful compared to a conventional office visit. Almost all parents were satisfied with the programme and the technology that was used. Parental satisfaction with the programme was not influenced by prior computer ownership or comfort with technology. The programme appears to be feasible for a wide range of parents of children with TBI and provides an alternative to conventional office-based sessions that may not be accessible to all families.

    Computers, personal digital assistants (PDA), and the Internet are widely used as resources in medical education and clinical care. Educators who intend to incorporate these resources effectively into residency education programmes can benefit from understanding how residents currently use these tools, their skills, and their preferences. The researchers sent questionnaires to 306 US family medicine residency programmes for all of their residents to complete. Respondents were 1177 residents from 125 (41%) programmes. Access to a computer was reported by 95% of respondents. Of these, 97% of desktop and 89% of laptop computers could access the Internet. Residents accessed various educational and clinical resources. Half felt they had 'intermediate' skills at Web searches, 23% had 'some skills,' and 27% were 'quite skilled.' Those under 30 years of age reported higher skill levels. Those who experienced a Web-based curriculum in medical school reported higher search skills and greater success in finding clinical information. Respondents preferred to use technology to supplement the didactic sessions offered in resident teaching conferences. Favourable conditions exist in family medicine residency programmes to implement a blend of traditional and technology-based learning experiences. These conditions include residents' experience, skills, and preferences.

  10. Analog Module Architecture for Space-Qualified Field-Programmable Mixed-Signal Arrays

    1999-01-01

    Spacecraft require all manner of both digital and analog circuits. Onboard digital systems are constructed almost exclusively from field-programmable gate array (FPGA) circuits providing numerous advantages over discrete design including high integration density, high reliability, fast turn-around design cycle time, lower mass, volume, and power consumption, and lower parts acquisition and flight qualification costs. Analog and mixed-signal circuits perform tasks ranging from housekeeping to signal conditioning and processing. These circuits are painstakingly designed and built using discrete components due to a lack of options for field-programmability. FPAA (Field-Programmable Analog Array) and FPMA (Field-Programmable Mixed-signal Array) parts exist but not in radiation-tolerant technology and not necessarily in an architecture optimal for the design of analog circuits for spaceflight applications. This paper outlines an architecture proposed for an FPAA fabricated in an existing commercial digital CMOS process used to make radiation-tolerant antifuse-based FPGA devices. The primary concerns are the impact of the technology and the overall array architecture on the flexibility of programming, the bandwidth available for high-speed analog circuits, and the accuracy of the components for high-performance applications.

    Schultz, Martin G.; Klemp, Dieter; Wahner, Andreas

    Die Qualität der Luft beeinflusst in besonderer Weise die menschliche Gesundheit und hat auch Auswirkungen auf die Landwirtschaft und Ökosysteme. Viele Luftschadstoffe absorbieren oder streuen zudem die Sonnen- oder Wärmestrahlung und sind daher klimawirksam. Luftchemische Prozesse hängen, ebenso wie die Emissionen, von klimatischen Faktoren wie Sonneneinstrahlung, Temperatur und Niederschlag ab. Deshalb ist zu erwarten, dass die projizierten Klimaänderungen für Deutschland auch die Luftschadstoffkonzentrationen beeinflussen werden, auch wenn dieser Zusammenhang noch nicht gut erforscht ist. Dieses Kapitel vermittelt einen Überblick über die Zusammenhänge und weist zumindest qualitativ auf mögliche künftige Entwicklungen hin. Im Vordergrund stehen die Entwicklungen bei Feinstaub und Ozon.

    In einem vorhandenen Nachrichtennetz sorgt die Vermittlungstechnik dafür, dass Informationen zu jeder Zeit von einem beliebigen Zugangspunkt zu einem beliebigen anderen Zugangspunkt übertragen werden können. Der gesamte Vorgang wird mit Vermittlung bezeichnet. Das größte weltweit vorhandene Nachrichtennetz ist das kombinierte Internet-Telefonnetz. Die Zugangspunkte sind die Anschlusspunkte (ortsfeste Anschlussdosen) für die Endgeräte, wie z. B. Rechner, Telefonapparate, Faxgeräte oder Modems, oder aber ortsveränderliche Endgeräte wie Laptops, schnurlose Telefone oder Funktelefone ("Handys"). Die Vermittlungsstelle klassischer Art mit hierarchischem Aufbau ist nahezu vollständig durch komplexe rechnergesteuerte national arbeitende Anlagen ersetzt worden. In diesem Kapitel werden deshalb grundlegende Eigenschaften dargestellt. Stichworte: Grundbegriffe; Vermittlung; Verkehrstheorie; Endgeräte.

    Die Energieversorgung ist eine kritische Infrastruktur, da alle anderen Sektoren von der Stromversorgung abhängig sind und eine Störung katastrophale Auswirkungen mit unvorhersehbaren Kaskadeneffekten mit sich bringen würde. Das oberste Ziel der Betreiber ist daher sicherzustellen, dass Maßnahmen für eine störungsfreie Stromversorgung ergriffen werden. Cyberangriffe stellen ein hohes Risiko für die Energieversorgung dar. Dabei kann die Energiewirtschaft von Massenphänomenen wie Cybercrime betroffen sein, aber auch Gegenstand von technisch komplexer Cybersabotage werden, wie bei dem Angriff Ende 2015 auf einen ukrainischen Energieversorger. Die Stromversorgung fiel für mehrere Stunden aus und hatte weitreichende Auswirkungen für die Bevölkerung und Unternehmen.

  18. Zum Wissenschaftsverständnis der modernen Evolutionsbiologie

    NASA Astrophysics Data System (ADS)

    Sommer, Ralf J.

    Die moderne Evolutionsbiologie hat ihren Ursprung in den Arbeiten von Charles Darwin und Alfred Wallace (Darwin 1963). Der gemeinsame Ausgangspunkt des Evolutionsgedanken ist dabei die Beobachtung, dass die biologische Welt nicht konstant ist. Biologische Systeme und alle darin lebenden Organismen unterliegen über längere Zeiträume hinweg einer stetigen Veränderung. Diese grundlegende Eigenschaft biologischer Systeme macht die Biologie zu einer historischen Wissenschaft und stellt einen wichtigen Gegensatz zu großen Teilen der Physik dar. Obwohl die Aussage von der Veränderlichkeit der Arten heute trivial klingt, war sie im 19. Jahrhundert eine Revolution, da die Konstanz der Arten und der Welt eine vorherrschende Stellung im damaligen Weltbild hatte (Amundson 2005).

    Die Dynamik und Thermodynamik großer kosmischer Systeme ist fast unabhängig von den besonderen Theorien über die Gravitation. Nur die Feinstruktur der Kosmologie und Kosmonogie reflektiert die speziellen Hypothesen. Diese Neutralität gegenüber den konkreten Gravodynamiken ist die Konsequenz der fundamentalen Eigenschaften der Gravitation: Der Prinzipien der Äquivalenz von Trägheit und Schwere. The dynamics and thermodynamics of great cosmical systems are nearly independent of the theory of gravitation and only the fine-structure of cosmogony and cosmology reflects the special hypotheses.The neutrality against the concret gravodynamics is a consequence of the fundamental properties of gravitation: the principlies of equivalence of gravity and inertia.

    Ellery, Alex; Richter, Lutz; Parnell, John; Baker, Adam

    2003-11-01

    We present a proposed robotic mission to Mars - Vanguard - for the Aurora Arrow programme which combines an extensive technology demonstrator with a high scientific return. The novel aspect of this technology demonstrator is the demonstration of "water mining" capabilities for in-situ resource utilisation in conjunction with high-value astrobiological investigation within a low mass lander package of 70 kg. The basic architecture comprises a small lander, a micro-rover and a number of ground-penetrating moles. This basic architecture offers the possibility of testing a wide variety of generic technologies associated with space systems and planetary exploration. The architecture provides for the demonstration of specific technologies associated with planetary surface exploration, and with the Aurora programme specifically. Technology demonstration of in-situ resource utilisation will be a necessary precursor to any future human mission to Mars. Furthermore, its modest mass overhead allows the reuse of the already built Mars Express bus, making it a very low cost option.

    The cerebral substratum of age-related cognitive decline was evaluated in an elderly-cohort followed for 12 years (n=306). Participants, free of dementia, received neuropsychological assessments every two years and an MRI exam at baseline and four years later. Cognitive decline was evaluated on two broadly used tests to detect dementia: the Free and Cued Selective Reminding Test (FCSRT), a verbal episodic memory task, and the Isaacs Set Test (IST), a semantic fluency task. Using voxel-based approach, the relationship between cognitive decline with 1/ baseline grey matter volumes and 2/ grey matter volume loss between the two scans was explored. Baseline volumes analysis revealed that FCSRT and IST declines were both associated with lower volumes of the medial temporal region. Volumes loss analysis confirmed that both declines are related to medial temporal lobe atrophy and revealed that FCSRT decline was specifically associated with atrophy of the posterior cingulate cortex whereas IST decline was specifically related to temporal pole atrophy. These results suggest that cognitive decline across aging is firstly related to structural modifications of the medial temporal lobe, followed by an atrophy in the posterior midline structures for episodic memory and an atrophy of the temporal pole for semantic fluency.

  17. Pre-launch Performance Assessment of the VIIRS Ice Surface Temperature Algorithm

    NASA Astrophysics Data System (ADS)

    2008-12-01

    The VIIRS Ice Surface Temperature (IST) environmental data product provides the surface temperature of sea-ice at VIIRS moderate resolution (750m) during both day and night. To predict the IST, the retrieval algorithm utilizes a split-window approach with Long-wave Infrared (LWIR) channels at 10.76 μm (M15) and 12.01 μm (M16) to correct for atmospheric water vapor. The split-window approach using these LWIR channels is AVHRR and MODIS heritage, where the MODIS formulation has a slightly modified functional form. The algorithm relies on the VIIRS Cloud Mask IP for identifying cloudy and ocean pixels, the VIIRS Ice Concentration IP for identifying ice pixels, and the VIIRS Aerosol Optical Thickness (AOT) IP for excluding pixels with AOT greater than 1.0. In this paper, we will report the pre-launch performance assessment of the IST retrieval. We have taken two separate approaches to perform this assessment, one based on global synthetic data and the other based on proxy data from Terra MODIS. Results of the split- window algorithm have been assessed by comparison either to synthetic "truth" or results of the MODIS retrieval. We will also show that the results of the assessment with proxy data are consistent with those obtained using the global synthetic data.

    Basic vacuum calculations were performed for various operating conditions of the Los Alamos National Neutron Science H{sup −} Cockcroft-Walton (CW) injector and the Ion Source Test Stand (ISTS). The vacuum pressure was estimated for both the CW and ISTS at five different points: (1) inside the H{sup −} ion source, (2) in front of the Pierce electrode, (3) at the extraction electrode, (4) at the column electrode, and (5) at the ground electrode. A static vacuum analysis of residual gases and the working hydrogen gas was completed for the normal ion source working regime. Gas density and partial pressure weremore » estimated for the injected hydrogen gas. The attenuation of H{sup −} beam current and generation of electron current in the high voltage acceleration columns and low energy beam transport lines were calculated. The interaction of H{sup −} ions on molecular hydrogen (H{sub 2}) is discussed as a dominant collision process in describing electron stripping rates. These results are used to estimate the observed increase in the ratio of electrons to H{sup −} ion beam in the ISTS beam transport line.« less

  19. Microspheres in Plasma Display Panels

    NASA Technical Reports Server (NTRS)

    2006-01-01

    Filling small bubbles of molten glass with gases is just as difficult as it sounds, but the technical staff at NASA is not known to shy away from a difficult task. When Microsphere Systems, Inc. (MSI), of Ypsilanti, Michigan, and Imaging Systems Technology, Inc. (IST), of Toledo, Ohio, were trying to push the limits of plasma displays but were having difficulty with the designs, NASA s Glenn Garrett Morgan Commercialization Initiative (GMCI) assembled key personnel at Glenn Research Center and Ohio State University for a brainstorming session to come up with a solution for the companies. They needed a system that could produce hollow, glass micro-sized spheres (microspheres) that could be filled with a variety of gasses. But the extremely high temperature required to force the micro-sized glass bubbles to form at the tip of a metal nozzle resulted in severe discoloration of the microspheres. After countless experiments on various glass-metal combinations, they had turned to the GMCI for help. NASA experts in advanced metals, ceramics, and glass concluded that a new design approach was necessary. The team determined that what was needed was a phosphate glass composition that would remain transparent, and they went to work on a solution. Six weeks later, using the design tips from the NASA team, Tim Henderson, president of MSI, had designed a new system in which all surfaces in contact with the molten glass would be ceramic instead of metal. Meanwhile, IST was able to complete a Phase I Small Business Innovation Research (SBIR) grant supported by the National Science Foundation (NSF) and supply a potential customer with samples of the microspheres for evaluation as filler materials for high-performance insulations.

    Earth Observation data and remote sensing technologies have been maturing into useful tools that can be utilised by local authorities and businesses to aid in activates such as monitoring climate change trends and managing agricultural land and water uses. The European Earth observation programme Copernicus, previously known as GMES (Global Monitoring for Environment and Security), provides the means to collect and process multi-source EO and environmental data that supports policy developments at the European level. At the regional and local level, the Copernicus programme has been initiated through Regional Contact Office (RCO), which provide knowledge, training, and access to expertise both locally and at a European level through the network of RCOs established across Europe in the DORIS_Net (Downstream Observatory organised by Regions active In Space - Network) project (Grant Agreement No. 262789 Coordination and support action (Coordinating) FP7 SPA.2010.1.1-07 "Fostering downstream activities and links with regions"). In the East Midlands UK RCO, educational and training workshops and modules have been organised to highlight the wider range of tools and application available to businesses and local authorities in the region. Engagement with businesses and LRA highlighted the need to have a tiered system of training to build awareness prior to investigating innovative solutions and space technology uses for societal benefits. In this paper we outline education and training programmes which have been developed at G-STEP (GMES - Science and Technology Education Partnership), University of Leicester, UK to open up the Copernicus programme through the Regional Contact Office to downstream users such as local businesses and LRAs. Innovative methods to introduce the operational uses of Space technologies in real cases through e-learning modules and web-based tools will be described and examples of good practice for educational training in these sectors will be demonstrated. The results from these workshops and awareness building campaigns will show the end-user 'pull' in the uptake of remote sensing and Earth Observation data to implement successful Local Authority action plans and projects developing innovative solutions to critical Local Authority issues.

    All the recent DEMO design studies for helium cooled divertors utilize tungsten materials and alloys, mainly due to their high temperature strength, good thermal conductivity, low erosion, and comparably low activation under neutron irradiation. The long-term objective of the EFDA fusion materials programme is to develop structural as well as armor materials in combination with the necessary production and fabrication technologies for future divertor concepts. The programmatic roadmap is structured into four engineering research lines which comprise fabrication process development, structural material development, armor material optimization, and irradiation performance testing, which are complemented by a fundamental research programme on "Materials Science and Modeling". This paper presents the current research status of the EFDA experimental and testing investigations, and gives a detailed overview of the latest results on fabrication, joining, high heat flux testing, plasticity, modeling, and validation experiments.

    This session will describe a new NSF-funded project in Geoscience education, Inquiring with Geoscience Data Sets. The goals of the project are to (1) Study the impacts on student learning of Web-based supplementary curriculum modules that engage secondary-level students in inquiry projects addressing important geoscience problems using an Earth System Science approach. Students will use technologies to access real data sets in the geosciences and to interpret, analyze, and communicate findings based on the data sets. The standards addressed will include geoscience concepts, inquiry abilities in NSES and Benchmarks for Science Literacy, data literacy, NCTM standards, and 21st-century skills and technology proficiencies (NETTS/ISTE). (2) Develop design principles, specification templates, and prototype exemplars for technology-based performance assessments that provide evidence of students' geoscientific knowledge and inquiry skills (including data literacy skills) and students' ability to access, use, analyze, and interpret technology-based geoscience data sets. (3) Develop scenarios based on the specification templates that describe curriculum modules and performance assessments that could be developed for other Earth Science standards and curriculum programs. Also to be described in the session are the project's efforts to differentiate among the dimensions of data literacy and scientific inquiry that are relevant for the geoscience discplines, and how recognition and awareness of the differences can be effectively channelled for the betterment of geoscience education.

    2014-01-01

    The Resource Prospector Mission (RPM) is an in-situ resource utilization (ISRU) technology demonstration mission planned to launch in 2018. The mission will use the Regolith and Environment Science & Oxygen and Lunar Volatile Extraction (RESOLVE) Payload to prospect for lunar volatiles such as water, oxygen, and carbon dioxide. These compounds will validate ISRU capability. The payload, particularly the Lunar Advanced Volatile Analysis (LAVA) subsystem, requires numerous temperature measurements to accurately control on-board heaters that keep the volatiles in the vapor phase to allow quantification and prevent the clogging of delivery lines. Previous spaceflight missions have proven that Resistive Temperature Detector (RTD) failure impedes mission success. The research resulted in a recommendation for a flight-forward RTD. The recommendation was based on accuracy, consistency, and ease of installation of RTDs procured from IST, QTI, and Honeywell.

    Background and Purpose— Computed tomographic angiography and magnetic resonance angiography are used increasingly to assess arterial patency in patients with ischemic stroke. We determined which baseline angiography features predict response to intravenous thrombolytics in ischemic stroke using randomized controlled trial data. Methods— We analyzed angiograms from the IST-3 (Third International Stroke Trial), an international, multicenter, prospective, randomized controlled trial of intravenous alteplase. Readers, masked to clinical, treatment, and outcome data, assessed prerandomization computed tomographic angiography and magnetic resonance angiography for presence, extent, location, and completeness of obstruction and collaterals. We compared angiography findings to 6-month functional outcome (Oxford Handicap Scale) and tested for interactions with alteplase, using ordinal regression in adjusted analyses. We also meta-analyzed all available angiography data from other randomized controlled trials of intravenous thrombolytics. Results— In IST-3, 300 patients had prerandomization angiography (computed tomographic angiography=271 and magnetic resonance angiography=29). On multivariable analysis, more extensive angiographic obstruction and poor collaterals independently predicted poor outcome (P<0.01). We identified no significant interaction between angiography findings and alteplase effect on Oxford Handicap Scale (P≥0.075) in IST-3. In meta-analysis (5 trials of alteplase or desmoteplase, including IST-3, n=591), there was a significantly increased benefit of thrombolytics on outcome (odds ratio>1 indicates benefit) in patients with (odds ratio, 2.07; 95% confidence interval, 1.18–3.64; P=0.011) versus without (odds ratio, 0.88; 95% confidence interval, 0.58–1.35; P=0.566) arterial obstruction (P for interaction 0.017). Conclusions— Intravenous thrombolytics provide benefit to stroke patients with computed tomographic angiography or magnetic resonance angiography evidence of arterial obstruction, but the sample was underpowered to demonstrate significant treatment benefit or harm among patients with apparently patent arteries.

  6. Capacity of lung stroma to educate dendritic cells inhibiting mycobacteria-specific T-cell response depends upon genetic susceptibility to tuberculosis.

    The balance between activation and inhibition of local immune responses in affected tissues during prolonged chronic infections is important for host protection. There is ample evidence that regulatory, tolerogenic dendritic cells (DC) are developed and present in tissues and inhibit overwhelming inflammatory reactions. Also, it was firmly established that stromal microenvironment of many organs is able to induce development of immature regulatory DC (DCreg), an essential element of a general immune regulatory network. However, direct experimental data demonstrating inhibition of immune responses by stroma-instructed immature DCreg in infectious models are scarce, and virtually nothing is known about functioning of this axis of immunity during tuberculosis (TB) infection. In this study, we demonstrate that lung stromal cells are capable of supporting the development in culture of immature CD11b(+)CD11c(low)CD103(-) DCreg from lineage-negative (lin(-)) bone marrow precursors. DCreg developed on lung stroma isolated from mice of genetically TB-hyper-susceptible I/St and relatively resistant B6 inbred strains inhibited proliferative response of mycobacteria-specific CD4(+) T-cell lines a dose-dependent manner. Importantly, the inhibitory activity of B6 DCreg was substantially higher than that of I/St Dcreg. Moreover, when the donors of stromal cells were chronically infected with virulent mycobacteria, the capacity to instruct inhibitory DCreg was retained in B6, but further diminished in I/St stromal cells. DCreg-provided suppression was mediated by a few soluble mediators, including PGE2, NO and IL-10. The content of CD4(+)Foxp3(+) Treg cells in the mediastinal, lung-draining lymph nodes at the advanced stages of chronic infection did not change in I/St, but increased 2-fold in B6 mice, and lung pathology was much more pronounced in the former mice. Taken together, these data provide genetic evidence that the capacity to maintain populations of regulatory cells during M. tuberculosis infection is a part of the host protective strategy.

    To analyze the clinical characteristics and to evaluate immunosuppressive therapy (IST) response and survival in hepatitis-associated aplastic anemia (HAAA). We retrospectively analyzed clinical characteristics, IST response, long-term survival and clonal evolution in 41 HAAA patients, and compared those with age and bone marrow failure matched idiopathic aplastic anemia (IAA) patients. The prevalence of HAAA among cases of SAA was 4.34% (41/944). The proportion of VSAA in HAAA cases was significantly higher than IAA (65.9% vs 39.4%, P=0.001). There was no significant difference in the prevalence of hemorrhage and infections between HAAA and IAA patients, but the duration of infection persistence in HAAA group was much longer than IAA group [21 (4-100) d vs 13 (3-139) d, P=0.048]. The absolute counts of CD3(+) T-cell, CD3(+)CD4(+)T-cell, CD3(+)CD8(+)T-cell and ratio of CD4(+) T-cell/CD8(+) T-cell in HAAA were significant lower than that in IAA patients. However, the percentage of CD3(+)CD8(+)T-cell in HAAA was significant higher than that in IAA (P <0.05). The total response in HAAA and IAA patients treated with IST were 34.1% vs 34.1% (P=1.000), 56.1% vs 53.7% (P=0.787), and 73.2% vs 68.3% (P=0.558) at 3, 6, 12 months after IST, respectively. There were no significant difference in 5-year overall survival and event-free survival between HAAA and IAA patients (90% vs 87.1%, P=0.700; 71.9% vs 62.4%, P=0.450). HAAA was a rare distinct variant of aplastic anemia with more severe bone marrow failure and more severe imbalance of the T cell immune system than IAA. Treatment outcomes were comparable in patients with HAAA and IAA.

  9. In eHealth in India today, the nature of work, the challenges and the finances: an interview-based study

    PubMed Central

    2014-01-01

    Background India is a country with vast unmet medical needs. eHealth has the potential to improve the quality of health care and reach the unreached. We have sought to understand the kinds of eHealth programmes being offered in India today, the challenges they face and the nature of their financing. Methods We have adopted an interview-based methodology. The 30 interviews represent 28 organizations, and include designers, implementers, evaluators and technology providers for eHealth programmes. Results A range of programmes is being run, including point-of-care in rural and urban areas, treatment compliance, data collection and disease surveillance, and distant medical education. Most programmes provide point-of-care to patients or other beneficiaries in rural areas. Technology is not a limiting factor but the unavailability of suitable health personnel is a major challenge, especially in rural areas. We have identified a few factors that help this situation. Financial sustainability is also a concern for most programmes, which have rarely been scaled up. There are recent for-profit efforts in urban areas, but no reliable business model has been identified yet. Government facilities have not been very effective in eHealth on their own, but collaborations between the government and non-profit (in particular) and for-profit organisations have led to impactful programmes. Conclusions It is unlikely that eHealth will have widespread and sustainable impact without government involvement, especially in rural areas. Nevertheless, programmes run solely by the government are unlikely to be the most effective. PMID:24387627

    St. Jude Medical's Cardiac Rhythm Management Division, formerly known as Pacesetter Systems, Inc., incorporated Apollo technology into the development of the programmable pacemaker system. This consists of the implantable pacemaker together with a physician's console containing the programmer and a data printer. Physician can communicate with patient's pacemaker by means of wireless telemetry signals transmitted through the communicating head held over the patient's chest. Where earlier pacemakers deliver a fixed type of stimulus once implanted, Programalith enables surgery free "fine tuning" of device to best suit the patient's changing needs.

    OLED technology has matured sufficiently to consider it a realistic candidate for military display applications. Manufacturing sources are transitioning from an early developer to a business focused and often rationalised supply base that already has a sustainable business model. New commercial products, with a growing list of applications are slowly swelling the list of available OLED display components that can be considered for military requirements. This paper describes an exploratory application of OLED technology to the Towed Artillery Digitisation (TAD) programme. The Gunners Display function in this system endures the most difficult environment available in Army programmes. By replicating the Gunners Display, we have confirmed that OLED technology is compatible with and technically almost ready for rugged military applications using newly available commercial sources.

    As part of the Intelligent Task Automation program, a team developed enabling technologies for programmable, sensory controlled manipulation in unstructured environments. These technologies include 2-D/3-D vision sensing and understanding, force sensing and high speed force control, 2.5-D vision alignment and control, and multiple processor architectures. The subsequent design of a flexible, programmable, sensor controlled robotic assembly system for small electromechanical devices is described using these technologies and ongoing implementation and integration efforts. Using vision, the system picks parts dumped randomly in a tray. Using vision and force control, it performs high speed part mating, in-process monitoring/verification of expected results and autonomous recovery from some errors. It is programmed off line with semiautomatic action planning.

    2003-01-15

    Reproductive techniques have a major impact on the structure of breeding programmes, the rate of genetic gain and dissemination of genetic gain in populations. This manuscript reviews the impact of reproductive technologies on the underlying components of genetic gain and inbreeding with special reference to the role of female reproductive technology. Evaluation of alternative breeding schemes should be based on genetic gain while constraining inbreeding. Optimum breeding schemes can be characterised by: decreased importance of sib information; increased accuracy at the expense of intensity; and a factorial mating strategy. If large-scale embryo cloning becomes feasible, this will have a small impact on the rate of genetic gain but will have a large impact on the structure of breeding programmes.

    In the spring of 2009, I participated in PolarTREC - Teachers and Researchers Exploring and Collaborating, a Teacher Research Experience (TRE) funded by the National Science Foundation and managed by the Arctic Research Consortium of the United States. I assisted in hands-on research being performed by scientists with OASIS (Ocean, Atmosphere, Sea Ice and Snowpack) during their field campaign in Barrow, Alaska. Although I was in the field for only 3 weeks, it was merely a beginning to a transformation that took place not only in me, but also among all of those involved. The PolarTREC program embodies the principles fundamental to the 21st Century skill-set that we want our students to possess. The job market is changing for graduates, and education is striving to provide students with the skills necessary to thrive in the future. To ensure the success of students the International Society for Technology Education (ISTE) has defined 21st Century Skills. They are incorporated into many educational standards (such as the Arizona Educational Technology Standards) and they are practiced by the teachers, researchers, students and the PolarTREC community. They are:

    • Creativity and Innovation
    • Communication and Collaboration
    • Research and Information Literacy
    • Critical Thinking, Problem Solving, and Decision Making

Challenges include cost-effectively meeting automotive safety, performance, and reliability standards. Worldwide automobile production' for 1987 is listed in Table 1. Of the roughly 33 million cars produced annually, approximately 8% are luxury models which are candidates for features such as auto- matically dimming rearview mirrors or variable opacity sunroofs. Thus copious commercial opportunities await whatever chromogenic technologies qualify for use in automobiles. This review will describe the performance, safety, and reliability/durability required for automotive use. Commercial opportunities and challenges will be discussed including cost factors and specifications. Chromogenic technologies such as electrochromism, liquid crystals and thermochromism will be reviewed in terms of how publicly announced technical developments match automotive needs and expectations. Construction and performance of ex- isting or imminent chromogenic devices will be described. Finally, how opportunities and challenges of the automotive environment translate to other applications for chromogenic materials such as architectural or information display devices will be discussed. The objective is to generally review the applications, the technologies appropriate to these applications, and the automotive chromogenic devices available at the time of writing to match these applications.

    • Our bodies are our own: resistance to ABC-based HIV-prevention programmes in northern Tanzanian conservation organisations.

      PubMed

      Reid-Hresko, John

      2014-01-01

      ABC-based HIV-prevention programmes have been widely employed in northern Tanzanian wildlife conservation settings in an attempt to (re)shape the sexual behaviours of conservation actors. Utilising findings from 66 semi-structured interviews conducted in 2009-2010, this paper examines ABC prevention as a form of Foucauldian governmentality--circulating technologies of power that mobilise disciplinary technologies and attempt to transform such efforts into technologies of the self--and explores how individuals understand and respond to attempts to govern their behaviour. ABC regimes attempt to rework subjectivity, positioning HIV-related behaviours within a risk-based neoliberal rationality. However, efforts to use ABC as a technology to govern populations and individual bodies are largely incommensurate with existing Tanzanian sociocultural formations, including economic and gendered inequalities, and local understandings of sexuality. The language research participants used to talk about ABC and the justifications they offered for non-compliance illuminate this discrepancy. Data reveal that the recipients of ABC campaigns are active producers of understandings that work for them in their lives, but may not produce the behavioural shifts envisioned by programme goals. These findings corroborate previous research, which questions the continued plausibility of ABC as a stand-alone HIV- prevention framework.

      2017-01-01

      Targeted genome editing with programmable nucleases has revolutionized biomedical research. The ability to make site-specific modifications to the human genome, has invoked a paradigm shift in gene therapy. Using gene editing technologies, the sequence in the human genome can now be precisely engineered to achieve a therapeutic effect. Zinc finger nucleases (ZFNs) were the first programmable nucleases designed to target and cleave custom sites. This article summarizes the advances in the use of ZFN-mediated gene editing for human gene therapy and discusses the challenges associated with translating this gene editing technology into clinical use.

      The Radiation Hardened Electronics for Space Environments (RHESE) project consists of a series of tasks designed to develop and mature a broad spectrum of radiation hardened and low temperature electronics technologies. Three approaches are being taken to address radiation hardening: improved material hardness, design techniques to improve radiation tolerance, and software methods to improve radiation tolerance. Within these approaches various technology products are being addressed including Field Programmable Gate Arrays (FPGA), Field Programmable Analog Arrays (FPAA), MEMS Serial Processors, Reconfigurable Processors, and Parallel Processors. In addition to radiation hardening, low temperature extremes are addressed with a focus on material and design approaches.

    • Turbulenzübergang in der Rohrströmung: Die Lösung eines alten Rätsels

      2006-09-01

      Die Strömung von Flüssigkeiten und Gasen durch eine Röhre kann zwei Zustände annehmen. Einer ist laminar, also gleichmäßig geordnet, einer ist zeitlich-räumlich verwirbelt und turbulent. Mit dem Übergang zur Turbulenz nimmt der Strömungswiderstand drastisch zu. Vor etwa 120 Jahren beschrieb Osborne Reynolds bereits das Verhalten der Rohrströmung sehr genau. Er beobachtete, dass der Turbulenzübergang sehr empfindlich von äußeren Störungen abhängt, was bislang rätselhaft blieb. Dieses Rätsel konnte nun mit einer Kombination aus Computerstudien, Konzepten aus der nichtlinearen Dynamik und speziell entwickelten Experimenten gelöst werden.

      Die Infektion mammalischer Zellen durch pathogene Bakterien ist biologisch immer noch nicht sicher geklärt. Mit Hilfe der Laserscanmikroskopie ist es mittlerweile aber möglich, räumliche Bilddaten von Zellproben zu erstellen, auf denen der Eindringvorgang der Bakterien in das Zellinnere durch verschieden leuchtende Fluoreszenzfarbstoffe visualisiert werden kann. Unter Verwendung bekannter und adaptierter 3D-Rekonstruktionsalgorithmen werden dreidimensionale Visualisierungen von Mikroskopiebildern vorgestellt, mit deren Hilfe die Analyse des Infektionsprozesses erleichtert wird. Dabei hat sich gezeigt, dass mit Oberflächenrekonstruktionsverfahren die Topografie der Zelloberfiäche korrekt dargestellt werden kann, während die Darstellung der Farbstoffverteilungen besser durch ein Texture-Mapping-Verfahren gelingt. Die Rekonstruktionen konnten insbesondere durch den Einsatz von stereoskopischen Visualisierungstechniken detailgenau analysiert werden.

      Im weitesten Sinne umfasst die musikalische Akustik alle Themenbereiche, in denen Akustik und Musik in irgendeiner Form miteinander verbunden sind oder zumindest gleichzeitig eine Rolle spielen (Meyer 2004a). Im Mittelpunkt steht dabei die Akustik der Musikinstrumente und Gesangsstimmen, die sich mit der physikalischen Funktionsweise einschließlich der Einflussmöglichkeiten des Spielers auf die Tongestaltung und mit der Schallabstrahlung einschließlich der Klangeigenarten und der Richtungsabhängigkeit befasst (Meyer 2004b, Fletcher u. Rossing 1991). Sobald dabei klangästhetische Gesichtspunkte mit ins Spiel kommen, ist eine Einbeziehung psychoakustischer Aspekte unumgänglich. Erst auf dieser Grundlage ist eine qualitative Bewertung von Instrumenten möglich, die es den Instrumentenbauern erlaubt, anhand objektiver Kriterien bautechnische Veränderungen zur Verbesserung ihrer Instrumente vorzunehmen.

  2. An FPGA-Based Test-Bed for Reliability and Endurance Characterization of Non-Volatile Memory

    NASA Technical Reports Server (NTRS)

    Rao, Vikram; Patel, Jagdish; Patel, Janak; Namkung, Jeffrey

    2001-01-01

    Memory technologies are divided into two categories. The first category, nonvolatile memories, are traditionally used in read-only or read-mostly applications because of limited write endurance and slow write speed. These memories are derivatives of read only memory (ROM) technology, which includes erasable programmable ROM (EPROM), electrically-erasable programmable ROM (EEPROM), Flash, and more recent ferroelectric non-volatile memory technology. Nonvolatile memories are able to retain data in the absence of power. The second category, volatile memories, are random access memory (RAM) devices including SRAM and DRAM. Writing to these memories is fast and write endurance is unlimited, so they are most often used to store data that change frequently, but they cannot store data in the absence of power. Nonvolatile memory technologies with better future potential are FRAM, Chalcogenide, GMRAM, Tunneling MRAM, and Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) EEPROM.

    2018-05-01

    Diverse perspectives are required to address the technological problems facing our world. Although women perform as well as their male counterparts in math and science prior to entering college, the numbers of women students entering and completing engineering programmes are far below their representation in the workforce. This paper reports on a qualitative, multiyear study of the experiences of women students in an Engineering Technology programme. The project addressed some of the unique, fundamental challenges that female students face within their programmes, and the authors describe a programmatic framework based on Self-Determination Theory as an intervention for the recruitment and retention of female engineering students. Data from focus groups and interviews show how students were supported in their undergraduate experiences and how inclusive learning environments are needed to further improve outcomes. Conceptual issues and methodological considerations of our outcomes are presented.

    Following the development of 1st Generation systems in the 1970s, thermal imaging has been in service with the UK armed forces for over 25 years and has proven itself to be a battle winning technology. More recently the wider accessibility to similar technologies within opposing forces has reduced the military advantage provided by these 1st Generation systems and a clear requirement has been identified by the UK MOD for thermal imaging sensors providing increased detection, recognition and identification (DRI) ranges together with a simplified logistical deployment burden and reduced through-life costs. In late 2005, the UK MOD initiated a programme known as "Albion" to develop high performance 3rd Generation single waveband infrared detectors to meet this requirement. At the same time, under a separate programme supporting higher risk technology, a dual waveband infrared detector was also developed. The development phase of the Albion programme has now been completed and prototype detectors are now available and have been integrated into demonstration thermal imaging cameras. The Albion programme has now progressed into the second phase, incorporating both single and dual waveband devices, focussing on low rate initial production (LRIP) and qualification of the devices for military applications. All of the detectors have been fabricated using cadmium mercury telluride material (CMT), grown by metal organic vapour phase epitaxy (MOVPE) on low cost, gallium arsenide (GaAs) substrates and bump bonded to the silicon read out circuit (ROIC). This paper discusses the design features of the 3rd Generation detectors developed in the UK together with the results obtained from the prototype devices both in the laboratory and when integrated into field deployable thermal imaging cameras.

    2016-02-01

    As Ireland's national seabed mapping programme, INFOMAR1 (INtegrated mapping FOr the sustainable development of Ireland's MARine resource) enters its eleventh year it continues to provide pivotal seabed mapping data products, e.g. databases, charts and physical habitat maps to support Ireland's Integrated Marine Plan. The programme, jointly coordinated by the Geological Survey of Ireland and the Marine Institute, has gained a world class reputation for developing seabed mapping technologies, infrastructure and expertise. In the government's current Integrated Marine Plan, the programme's critical role in marine spatial planning enabling infrastructural development, research and education has been cited2. INFOMAR's free data policy supports a thriving maritime economy by promoting easy access to seabed mapping datasets that underpin; maritime safety, security and surveillance, governance, business development, research and technology innovation and infrastructure. The first hydrographic surveys of the national marine mapping programme mapped the extent of Ireland's deepest offshore area, whilst in recent years the focus has been to map the coastal and shallow areas. Targeted coastal areas include 26 bays and 3 priority areas for which specialised equipment, techniques and vessels are required. This talk will discuss how the INFOMAR programme has evolved to address the scientific and technological challenges of seabed mapping across a range of water depths; particularly the challenges associated with addressing inshore data gaps. It will describe how the data converts to bathymetric and geological maps detailing seabed characteristics and habitats. We will expand on how maps are: incorporated into collaborative marine projects such as EMODnet, commercialised to identify marine resources and used as marine decision support tools that drive policy and promote protection of the vastly under discovered marine area.

  6. A reference architecture for telemonitoring.

    PubMed

    Clarke, Malcolm

    2004-01-01

    The Telecare Interactive Continuous Monitoring System exploits GPRS to provide an ambulatory device that monitors selected vital signs on a continuous basis. Alarms are sent when parameters fall outside preset limits, and accompanying physiological data may also be transmitted. The always-connected property of GPRS allows continuous interactive control of the device and its sensors, permitting changes to monitoring parameters or even enabling continuous monitoring of a sensor in emergency. A new personal area network (PAN) has been developed to support short-range wireless connection to sensors worn on the body including ECG and finger worn SpO2. Most notable is use of ultra low radio frequency to reduce power to minimum. The system has been designed to use a hierarchical architecture for sensors and "derived" signals, such as HR from ECG, so that each can be independently controlled and managed. Sensors are treated as objects, and functions are defined to control aspects of behaviour. These are refined in order to define a generic set of abstract functions to handle the majority of functions, leaving a minimum of sensor specific commands. The intention is to define a reference architecture in order to research the functionality and system architecture of a telemonitoring system. The Telecare project is funded through a grant from the European Commission (IST programme).

  7. Biometrics-based service marketing issues: exploring acceptability and risk factors of iris scans associated with registered travel programmes.

    PubMed

    Smith, Alan D

    2008-01-01

    The marketability and viability of biometric technologies by companies marketing their own versions of pre-approved registered travel programmes have generated a number of controversies. Data were collected and analysed to formulate graphs, run regression and correlation analyses, and use Chi-square to formally test basic research propositions on a sample of 241 professionals in the Pittsburgh area. It was found that there was a significant relationship between the respondents' familiarity with new technology (namely web-enabled and internet sophistication) and knowledge of biometrics, in particular iris scans. Participants who frequently use the internet are more comfortable with innovative technology; although individuals with higher income levels have less trust in the government, it appeared that virtually everyone is concerned about trusting the government with their personal information. Healthcare professionals need to document the safety, CRM-related factors, and provide leadership in the international collaboration of biometric-related personal identification technologies, since they will be one of the main beneficiaries of the implementation of such technologies.

    The 12th Transgenic Technology meeting was held in Edinburgh on 6th-8th October 2014 and interest to participate in the meeting overcame all expectations. The TT2014 was the largest meeting ever with more than 540 scientists, technicians, and students from all over the world. The meeting had an excellent scientific program that brought information on the latest ground-breaking technologies for gene targeting and genome editing using programmable nucleases into the foreground. These presentations were well balanced with several highlights over viewing topics in embryonic stem cell research, embryogenesis, disease models, and animals in agriculture. Ample space was reserved also for short talks presenting technical development and for highlighting posters contributions. A highlight of the meeting was the award of the 10th International Society of Transgenic Technologies Prize to Janet Rossant for her outstanding contributions in the field of mouse embryogenesis.

    The Education Office of the European Space Agency (ESA) offers university students, from ESA Member and Cooperating States, the opportunity to perform investigations in physical sciences, life sciences, and technology, under different gravity conditions through three educational programmes. The "Fly Your Thesis!" (FYT) programme makes use of parabolic flights and the "Drop Your Thesis!" (DYT) programme utilizes a drop tower as microgravity carriers, while the "Spin Your Thesis!" (SYT) programme uses a large centrifuge to create hypergravity. To date, more than hundred university students had the chance to participate in the design, development, and performance of one or more experiments during dedicated campaigns. In the following paper, we examine demographics of past participants of the ESA Education Office gravity-related opportunities over the past seven years and evaluate the benefits of these educational programmes for the participants' studies and careers. Student teams that participated in one of the programmes between 2009 and 2013 were contacted to fill in a questionnaire. The feedback from the students demonstrate significant benefits extending far beyond the primary educational objectives of these programmes.

    Dove, Erica; Astell, Arlene

    2017-01-01

    Engaging in enjoyable activities is an essential part of well-being, but people with dementia can find participation increasingly difficult. Motion-based technologies can provide meaningful engagement in a wide range of activities, but for people with dementia to take advantage of these devices requires a good understanding of how best to select and present these activities to this population. The objective of this study was to explore the use of motion-based technology (Xbox Kinect) as a group activity for people with dementia who attend adult day programmes. This qualitative study took place in an adult day programme for older adults with age-related challenges. Participants (n = 23) were observed while playing a digital bowling game presented on Xbox Kinect one hour per week for a period of 20 weeks, to capture naturalistic data. Field notes generated through observations were transcribed and analysed to identify emerging themes. The findings revealed three predominant themes which illustrate the potential of motion-based technology as a group activity for people with dementia who attend adult day programmes: (a) the importance of having a trained trainer, (b) learning versus mastery and (c) playing 'independently together'. People with dementia can learn to play games presented on motion-based technology and enjoy doing so. Furthermore, using the technology in a group setting fostered an encouraging and supportive environment which further contributed to the leisure experience. However, to be used most effectively, staff must be trained to set-up and interact with the technology, as well as introduce, teach and support people with dementia to use it.

  19. Nomadic migration : a service environment for autonomic computing on the Grid

    NASA Astrophysics Data System (ADS)

    Lanfermann, Gerd

    2003-06-01

    In recent years, there has been a dramatic increase in available compute capacities. However, these “Grid resources” are rarely accessible in a continuous stream, but rather appear scattered across various machine types, platforms and operating systems, which are coupled by networks of fluctuating bandwidth. It becomes increasingly difficult for scientists to exploit available resources for their applications. We believe that intelligent, self-governing applications should be able to select resources in a dynamic and heterogeneous environment: Migrating applications determine a resource when old capacities are used up. Spawning simulations launch algorithms on external machines to speed up the main execution. Applications are restarted as soon as a failure is detected. All these actions can be taken without human interaction. A distributed compute environment possesses an intrinsic unreliability. Any application that interacts with such an environment must be able to cope with its failing components: deteriorating networks, crashing machines, failing software. We construct a reliable service infrastructure by endowing a service environment with a peer-to-peer topology. This “Grid Peer Services” infrastructure accommodates high-level services like migration and spawning, as well as fundamental services for application launching, file transfer and resource selection. It utilizes existing Grid technology wherever possible to accomplish its tasks. An Application Information Server acts as a generic information registry to all participants in a service environment. The service environment that we developed, allows applications e.g. to send a relocation requests to a migration server. The server selects a new computer based on the transmitted resource requirements. It transfers the application's checkpoint and binary to the new host and resumes the simulation. Although the Grid's underlying resource substrate is not continuous, we achieve persistent computations on Grids by relocating the application. We show with our real-world examples that a traditional genome analysis program can be easily modified to perform self-determined migrations in this service environment. In den vergangenen Jahren ist es zu einer dramatischen Vervielfachung der verfügbaren Rechenzeit gekommen. Diese 'Grid Ressourcen' stehen jedoch nicht als kontinuierlicher Strom zur Verfügung, sondern sind über verschiedene Maschinentypen, Plattformen und Betriebssysteme verteilt, die jeweils durch Netzwerke mit fluktuierender Bandbreite verbunden sind. Es wird für Wissenschaftler zunehmend schwieriger, die verfügbaren Ressourcen für ihre Anwendungen zu nutzen. Wir glauben, dass intelligente, selbstbestimmende Applikationen in der Lage sein sollten, ihre Ressourcen in einer dynamischen und heterogenen Umgebung selbst zu wählen: Migrierende Applikationen suchen eine neue Ressource, wenn die alte aufgebraucht ist. 'Spawning'-Anwendungen lassen Algorithmen auf externen Maschinen laufen, um die Hauptanwendung zu beschleunigen. Applikationen werden neu gestartet, sobald ein Absturz endeckt wird. Alle diese Verfahren können ohne menschliche Interaktion erfolgen. Eine verteilte Rechenumgebung besitzt eine natürliche Unverlässlichkeit. Jede Applikation, die mit einer solchen Umgebung interagiert, muss auf die gestörten Komponenten reagieren können: schlechte Netzwerkverbindung, abstürzende Maschinen, fehlerhafte Software. Wir konstruieren eine verlässliche Serviceinfrastruktur, indem wir der Serviceumgebung eine 'Peer-to-Peer'-Topology aufprägen. Diese “Grid Peer Service” Infrastruktur beinhaltet Services wie Migration und Spawning, als auch Services zum Starten von Applikationen, zur Dateiübertragung und Auswahl von Rechenressourcen. Sie benutzt existierende Gridtechnologie wo immer möglich, um ihre Aufgabe durchzuführen. Ein Applikations-Information- Server arbeitet als generische Registratur für alle Teilnehmer in der Serviceumgebung. Die Serviceumgebung, die wir entwickelt haben, erlaubt es Applikationen z.B. eine Relokationsanfrage an einen Migrationsserver zu stellen. Der Server sucht einen neuen Computer, basierend auf den übermittelten Ressourcen-Anforderungen. Er transferiert den Statusfile des Applikation zu der neuen Maschine und startet die Applikation neu. Obwohl das umgebende Ressourcensubstrat nicht kontinuierlich ist, können wir kontinuierliche Berechnungen auf Grids ausführen, indem wir die Applikation migrieren. Wir zeigen mit realistischen Beispielen, wie sich z.B. ein traditionelles Genom-Analyse-Programm leicht modifizieren lässt, um selbstbestimmte Migrationen in dieser Serviceumgebung durchzuführen.

    Field Programmable Gate Arrays commonly called FPGA's are the newer generation of field programmable devices and offer more flexibility in the logic modules they incorporate and in how they are interconnected. The flexibility, the number of logic building blocks available, and the high gate densities achievable are why users find FPGA's attractive. These attributes are important in reducing product development costs and shortening the development cycle. The aerospace community is interested in incorporating this new generation of field programmable technology in space applications. To this end, a consortium was formed to evaluate the quality, reliability, and radiation performance of FPGA's. This report presents the test results on FPGA parts provided by ACTEL Corporation.

  1. Outcomes for engineering students delivering a STEM education and outreach programme

    2017-11-01

    University science outreach programmes are used to encourage more school students to select science, technology, engineering, and mathematics (STEM) subjects in further education and pursue science-related careers. The benefits of science outreach programmes are often espoused from the perspective of programme participants. Little attention, however, is given to what university students delivering the programmes gain from the experience. This paper seeks to illustrate the benefits of engineering students delivering STEM outreach programmes in schools. It reports on a qualitative case study of the experiences of two STEM Education and Outreach team members from a regional university in Australia. Content analysis of interview data highlighted not only the participants' motivations and perceived benefits of being involved in the STEM programme but also revealed the skills and attributes honed throughout the experience. Involvement in the STEM outreach programme resulted in the development of social and personal responsibility generic graduate attribute skills, evidenced through their motivations to be involved, the demonstration of understanding of teaching and learning, and application of science communication skills. This study demonstrates that designing and delivering STEM outreach programmes assists in the development of skills that will be beneficial when pursuing careers in engineering in the future.

  3. Small Satellites and the Nigerian National Space Programme

    NASA Astrophysics Data System (ADS)

    2002-01-01

    Space technology and access to space have been elusive to most developing countries over the last half of the 21st century, which is attributed to very low par capital income and the lack of awareness of policy/decision makers about the role of space technology in national development. Space technology was seen as very expensive and prestigious, meant only for the major industrialized countries, while the developing countries should focus on building their national economy and providing food, shelter and other social amenities for their ever-growing populations. In the last decade, the trend has changed with many developing countries embracing spaced technology as one of the major ways of achieving sustainable development. The present trend towards the use of small satellites in meeting national needs has aided this transition because, apart from the small size, they are cheaper to build and to launch, with shorter development time, lower complexity, improved effectiveness and reduced operating costs. This in turn has made them more affordable and has opened up new avenues for the acquisition of satellite technology. The collaborative work between National Space Research and Development Agency of Nigeria (NASRDA) and Surrey Satellite and Technology Limited (SSTL) is a programme aimed at building two small satellites as a way of kick- starting the national space programme. The first project, NigeriaSAT-1, is an enhanced microsatellite carrying Earth observation payloads able to provide 32 metre GSD 3 band multispectral images with a 600km swath width. NigeriaSAT-1 is one of six microsatellites forming the Disaster Monitoring Constellation (DMC) alongside microsatellites contributed by Algeria, China, Turkey, Thailand and UK. Through participation in this international constellation, Nigeria will be able to receive images with a daily revisit worldwide. The EO images generated by NigeriaSAT-1 and the partner microsatellites will be used for providing rapid coverage of natural and man-made disasters but will also be used for monitoring rapidly changing and dynamic aspect of agriculture, the environment, pipeline oil spillages and other national remote sensing requirements. Commercial exploitation of this unique 24hr revisit EO data is planned to offset the government investment. The second national project is NigeriaSAT-2, which is a geostationary communications minisatellite that has been selected specifically to address the lack of communications infrastructure in Nigeria. Both NigeriaSAT-1 and NigeriaSAT-2 projects are being carried out in co-operation with the Surrey Space Centre (UK), combined with a detailed space know-how transfer and training to build up an indigenous Nigeria capability in space technology, EO and communications. While the acquisition and development space technology is the prime focus of the national space programme, an application center, education center and various space research centers are being formed to draw the maximum benefit of space activities for Nigeria. The paper will present the experience of Nigeria in examining the cost/benefit of an affordable space programme based upon small satellites with real applications that will benefit the people of the country. The Nigerian space policy and programme and its first two small satellite projects (NigeriaSAT-1/DMC and NigeriaSAT-2/GEMINI) will also be presented. This paper focuses on how a developing country can take advantage of a cheap and efficient means of gaining access to space and using space technology in achieving its socio-economic development plans.

  11. Decision technologies and the independent professional: the future's challenge to learning and leadership

    PubMed Central

    Dowie, J.

    2001-01-01

    Most references to "leadership" and "learning" as sources of quality improvement in medical care reflect an implicit commitment to the decision technology of "clinical judgement". All attempts to sustain this waning decision technology by clinical guidelines, care pathways, "evidence based practice", problem based curricula, and other stratagems only increase the gap between what is expected of doctors in today's clinical situation and what is humanly possible, hence the morale, stress, and health problems they are increasingly experiencing. Clinical guidance programmes based on decision analysis represent the coming decision technology, and proactive adaptation will produce independent doctors who can deliver excellent evidence based and preference driven care while concentrating on the human aspects of the therapeutic relation, having been relieved of the unbearable burdens of knowledge and information processing currently laid on them. History is full of examples of the incumbents of dominant technologies preferring to die than to adapt, and medicine needs both learning and leadership if it is to avoid repeating this mistake.

  12. Theorising big IT programmes in healthcare: strong structuration theory meets actor-network theory.

    PubMed

    Greenhalgh, Trisha; Stones, Rob

    2010-05-01

    The UK National Health Service is grappling with various large and controversial IT programmes. We sought to develop a sharper theoretical perspective on the question "What happens - at macro-, meso- and micro-level - when government tries to modernise a health service with the help of big IT?" Using examples from data fragments at the micro-level of clinical work, we considered how structuration theory and actor-network theory (ANT) might be combined to inform empirical investigation. Giddens (1984) argued that social structures and human agency are recursively linked and co-evolve. ANT studies the relationships that link people and technologies in dynamic networks. It considers how discourses become inscribed in data structures and decision models of software, making certain network relations irreversible. Stones' (2005) strong structuration theory (SST) is a refinement of Giddens' work, systematically concerned with empirical research. It views human agents as linked in dynamic networks of position-practices. A quadripartite approcach considers [a] external social structures (conditions for action); [b] internal social structures (agents' capabilities and what they 'know' about the social world); [c] active agency and actions and [d] outcomes as they feed back on the position-practice network. In contrast to early structuration theory and ANT, SST insists on disciplined conceptual methodology and linking this with empirical evidence. In this paper, we adapt SST for the study of technology programmes, integrating elements from material interactionism and ANT. We argue, for example, that the position-practice network can be a socio-technical one in which technologies in conjunction with humans can be studied as 'actants'. Human agents, with their complex socio-cultural frames, are required to instantiate technology in social practices. Structurally relevant properties inscribed and embedded in technological artefacts constrain and enable human agency. The fortunes of healthcare IT programmes might be studied in terms of the interplay between these factors. Copyright 2010 Elsevier Ltd. All rights reserved.

    Die vorliegende überarbeitete Leitlinie zum Lipödem wurde unter der Federführung der Deutschen Gesellschaft für Phlebologie (DGP) erstellt und finanziert. Die Inhalte beruhen auf einer systematischen Literaturrecherche und dem Konsens von acht medizinischen Fachgesellschaften und Berufsverbänden. Die Leitlinie beinhaltet Empfehlungen zu Diagnostik und Therapie des Lipödems. Die Diagnose ist dabei auf der Basis von Anamnese und klinischem Befund zu stellen. Charakteristisch ist eine umschriebene, symmetrisch lokalisierte Vermehrung des Unterhautfettgewebes an den Extremitäten mit deutlicher Disproportion zum Stamm. Zusätzlich finden sich Ödeme, Hämatomneigung und eine gesteigerte Schmerzhaftigkeit der betroffenen Körperabschnitte. Weitere apparative Untersuchungen sind bisher besonderen Fragestellungen vorbehalten. Die Erkrankung ist chronisch progredient mit individuell unterschiedlichem und nicht vorhersehbarem Verlauf. Die Therapie besteht aus vier Säulen, die individuell kombiniert und an das aktuelle Beschwerdebild angepasst werden sollten: komplexe physikalische Entstauungstherapie (manuelle Lymphdrainage, Kompressionstherapie, Bewegungstherapie, Hautpflege), Liposuktion und plastisch-chirurgische Interventionen, Ernährung und körperliche Aktivität sowie ggf. additive Psychotherapie. Operative Maßnahmen sind insbesondere dann angezeigt, wenn trotz konsequent durchgeführter konservativer Therapie noch Beschwerden bestehen bzw. eine Progredienz des Befundes und/oder der Beschwerden auftritt. Eine begleitend zum Lipödem bestehende morbide Adipositas sollte vor einer Liposuktion therapeutisch angegangen werden. © 2017 The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

  14. Application of CRAFT (complete reduction to amplitude frequency table) in nonuniformly sampled (NUS) 2D NMR data processing.

    PubMed

    Krishnamurthy, Krish; Hari, Natarajan

    2017-09-15

    The recently published CRAFT (complete reduction to amplitude frequency table) technique converts the raw FID data (i.e., time domain data) into a table of frequencies, amplitudes, decay rate constants, and phases. It offers an alternate approach to decimate time-domain data, with minimal preprocessing step. It has been shown that application of CRAFT technique to process the t 1 dimension of the 2D data significantly improved the detectable resolution by its ability to analyze without the use of ubiquitous apodization of extensively zero-filled data. It was noted earlier that CRAFT did not resolve sinusoids that were not already resolvable in time-domain (i.e., t 1 max dependent resolution). We present a combined NUS-IST-CRAFT approach wherein the NUS acquisition technique (sparse sampling technique) increases the intrinsic resolution in time-domain (by increasing t 1 max), IST fills the gap in the sparse sampling, and CRAFT processing extracts the information without loss due to any severe apodization. NUS and CRAFT are thus complementary techniques to improve intrinsic and usable resolution. We show that significant improvement can be achieved with this combination over conventional NUS-IST processing. With reasonable sensitivity, the models can be extended to significantly higher t 1 max to generate an indirect-DEPT spectrum that rivals the direct observe counterpart.

    Medikamenten-beschichtete Ballons bei femoro-poplitealen Läsionen  Medikamenten-beschichtete Ballons (DCB) führen in der Behandlung von femoro-poplitealen Läsionen zu besseren Offenheitsraten als die einfache Ballondilatation und zu ähnlichen bis besseren Offenheitsraten als die Stentimplantation. Vorteil ist die Vermeidung von permanentem Fremdmaterial in Regionen, die einer ständigen mechanischen Beanspruchung unterworfen sind und die Möglichkeit, die Prozedur an derselben Stelle wiederholen zu können bzw. chirurgische Zugangswege offenzuhalten. Bei Auftreten von Dissektionen oder einem Recoil bietet sich die fokale Implantation möglichst kurzer Stents in den betroffenen Segmenten an. Die primäre Implantation Medikamenten-beschichteter Stents zeigt darüber hinaus keinen weiteren Vorteil und ist auf längere Sicht mit den Nachteilen der Implantation von Fremdmaterial in Bewegungssegmenten behaftet. Nicht medikamentöse und medikamentöse Begleittherapie  Die Kombination aus interventioneller Behandlung und supervidiertem Gehtraining zeigt die besten Erfolgsaussichten einer dauerhaften Verbesserung der Gehstrecke bei Patienten mit femoro-poplitealen Läsionen und ist einer alleinigen interventionellen Behandlung oder einem alleinigen Gehtraining überlegen. Darüber hinaus werden aktuell große randomisierte, kontrollierte Studien durchgeführt, die den Einfluss niedrig dosierter direkter Antikoagulanzien auf die kardiovaskuläre Komplikationsrate nach Intervention untersuchen. Die Ergebnisse dieser Studien werden Aufschluss geben über die optimale antithrombotische Therapie nach Intervention im femoro-poplitealen Stromgebiet.

  16. Influence of divergent and convergent thinking on visuomotor adaptation in young and older adults.

    Visuomotor adaptation declines in older age. This has been attributed to cognitive impairments. One relevant cognitive function could be creativity, since creativity is implicated as mediator of early learning. The present study therefore evaluates whether two aspects of creativity, divergent and convergent thinking, are differentially involved in the age-dependent decline of visuomotor adaptation. In 25 young and 24 older volunteers, divergent thinking was assessed by the alternative-uses-task (AUT), convergent thinking by the Intelligenz-Struktur-Test-2000 (IST), and sensorimotor-adaptation by a pointing task with 60° rotated visual feedback. Young participants outperformed older participants in all three tasks. AUT scores were positively associated with young but not older participants' adaptive performance, whereas IST scores were negatively associated with older but not young participants' adaptive performance. This pattern of findings could be attributed to a consistent relationship between AUT, IST and adaptation; taking this into account, adaptation deficits of older participants were no longer significant. We conclude that divergent thinking supports workaround-strategies during adaptation, but doesn't influence visuomotor recalibration. Furthermore, the decay of divergent thinking in older adults may explain most of age-related decline of adaptive strategies. When the age-related decay of divergent thinking coincides with well-preserved convergent thinking, adaptation suffers most. Copyright © 2015 Elsevier B.V. All rights reserved.

    2014-01-01

    Recent advances in the treatment of aplastic anemia (AA) made most of patients to expect to achieve a long-term survival. Allogeneic stem cell transplantation (SCT) from HLA-matched sibling donor (MSD-SCT) is a preferred first-line treatment option for younger patients with severe or very severe AA, whereas immunosuppressive treatment (IST) is an alternative option for others. Horse anti-thymocyte globuline (ATG) with cyclosporin A (CsA) had been a standard IST regimen with acceptable response rate. Recently, horse ATG had been not available and replaced with rabbit ATG in most countries. Subsequently, recent comparative studies showed that the outcomes of patients who received rabbit ATG/CsA were similar or inferior compared to those who received horse ATG/CsA. Therefore, further studies to improve the outcomes of IST, including additional eltrombopag, are necessary. On the other hand, the upper age limit of patients who are able to receive MSD-SCT as first-line treatment is a current issue because of favorable outcomes of MSD-SCT of older patients using fludarabine-based conditioning. In addition, further studies to improve the outcomes of patients who receive allogeneic SCT from alternative donors are needed. In this review, current issues and the newly emerging trends that may improve their outcomes in near futures will be discussed focusing the management of patients with AA. PMID:25378968

  18. Inverse scattering transform and soliton solutions for square matrix nonlinear Schrödinger equations with non-zero boundary conditions

    NASA Astrophysics Data System (ADS)

    2018-04-01

    The inverse scattering transform (IST) with non-zero boundary conditions at infinity is developed for an m × m matrix nonlinear Schrödinger-type equation which, in the case m = 2, has been proposed as a model to describe hyperfine spin F = 1 spinor Bose-Einstein condensates with either repulsive interatomic interactions and anti-ferromagnetic spin-exchange interactions (self-defocusing case), or attractive interatomic interactions and ferromagnetic spin-exchange interactions (self-focusing case). The IST for this system was first presented by Ieda et al. (2007) , using a different approach. In our formulation, both the direct and the inverse problems are posed in terms of a suitable uniformization variable which allows to develop the IST on the standard complex plane, instead of a two-sheeted Riemann surface or the cut plane with discontinuities along the cuts. Analyticity of the scattering eigenfunctions and scattering data, symmetries, properties of the discrete spectrum, and asymptotics are derived. The inverse problem is posed as a Riemann-Hilbert problem for the eigenfunctions, and the reconstruction formula of the potential in terms of eigenfunctions and scattering data is provided. In addition, the general behavior of the soliton solutions is analyzed in detail in the 2 × 2 self-focusing case, including some special solutions not previously discussed in the literature.

  20. Das Lektin aus der Erbse Pisum sativum : Bindungsstudien, Monomer-Dimer-Gleichgewicht und Rückfaltung aus Fragmenten

    NASA Astrophysics Data System (ADS)

    Küster, Frank

    2002-11-01

    Das Lektin aus Pisum sativum, der Gartenerbse, ist Teil der Familie der Leguminosenlektine. Diese Proteine haben untereinander eine hohe Sequenzhomologie, und die Struktur ihrer Monomere, ein all-ß-Motiv, ist hoch konserviert. Dagegen gibt es innerhalb der Familie eine große Vielfalt an unterschiedlichen Quartärstrukturen, die Gegenstand kristallographischer und theoretischer Arbeiten waren. Das Erbsenlektin ist ein dimeres Leguminosenlektin mit einer Besonderheit in seiner Struktur: Nach der Faltung in der Zelle wird aus einem Loop eine kurze Aminosäuresequenz herausgeschnitten, so dass sich in jeder Untereinheit zwei unabhängige Polypeptidketten befinden. Beide Ketten sind aber stark miteinander verschränkt und bilden eine gemeinsame strukturelle Domäne. Wie alle Lektine bindet Erbsenlektin komplexe Oligosaccharide, doch sind seine physiologische Rolle und der natürliche Ligand unbekannt. In dieser Arbeit wurden Versuche zur Entwicklung eines Funktionstests für Erbsenlektin durchgeführt und seine Faltung, Stabilität und Monomer-Dimer-Gleichgewicht charakterisiert. Um die spezifische Rolle der Prozessierung für Stabilität und Faltung zu untersuchen, wurde ein unprozessiertes Konstrukt in E. coli exprimiert und mit der prozessierten Form verglichen. Beide Proteine zeigen die gleiche kinetische Stabilität gegenüber chemischer Denaturierung. Sie denaturieren extrem langsam, weil nur die isolierten Untereinheiten entfalten können und das Monomer-Dimer-Gleichgewicht bei mittleren Konzentrationen an Denaturierungsmittel auf der Seite der Dimere liegt. Durch die extrem langsame Entfaltung zeigen beide Proteine eine apparente Hysterese im Gleichgewichtsübergang, und es ist nicht möglich, die thermodynamische Stabilität zu bestimmen. Die Stabilität und die Geschwindigkeit der Assoziation und Dissoziation in die prozessierten bzw. nichtprozessierten Untereinheiten sind für beide Proteine gleich. Darüber hinaus konnte gezeigt werden, dass auch unter nicht-denaturierenden Bedingungen die Untereinheiten zwischen den Dimeren ausgetauscht werden. Die Renaturierung der unprozessierten Variante ist unter stark nativen Bedingungen zu 100 % möglich. Das prozessierte Protein dagegen renaturiert nur zu etwa 50 %, und durch die Prozessierung ist die Faltung stark verlangsamt, der Faltungsprozess ist erst nach mehreren Tagen abgeschlossen. Im Laufe der Renaturierung wird ein Intermediat populiert, in dem die längere der beiden Polypeptidketten ein Homodimer mit nativähnlicher Untereinheitenkontaktfläche bildet. Der geschwindigkeitsbestimmende Schritt der Renaturierung ist die Assoziation der entfalteten kürzeren Kette mit diesem Dimer. The lectin from Pisum sativum (garden pea) is a member of the family of legume lectins. These proteins share a high sequence homology, and the structure of their monomers, an all-ß-motif, is highly conserved. Their quaternary structures, however, show a great diversity which has been subject to cristallographic and theoretical studies. Pea lectin is a dimeric legume lectin with a special structural feature: After folding is completed in the cell, a short amino acid sequence is cut out of a loop, resulting in two independent polypeptide chains in each subunit. Both chains are closely intertwined and form one contiguous structural domain. Like all lectins, pea lectin binds to complex oligosaccharides, but its physiological role and its natural ligand are unknown. In this study, experiments to establish a functional assay for pea lectin have been conducted, and its folding, stability and monomer-dimer-equilibrium have been characterized. To investigate the specific role of the processing for stability and folding, an unprocessed construct was expressed in E. coli and compared to the processed form. Both proteins have the same kinetic stability against chemical denaturant. They denature extremely slowly, because only the isolated subunits can unfold, and the monomer-dimer-equilibrium favors the dimer at moderate concentrations of denaturant. Due to the slow unfolding, both proteins exhibit an apparent hysteresis in the denaturation transition. Therefore it has not been possible to determine their thermodynamic stability. For both proteins, the stability and the rates of association and dissociation into processed or unprocessed subunits, respectively, are equal. Furthermore it could be shown that even under non-denaturing conditions the subunits are exchanged between dimers. Renaturation of the unprocessed variants is possible under strongly native conditions with 100 % yield. The processed protein, however, can be renatured with yields of about 50 %, and its refolding is strongly decelerated. The folding process is finished only after several days. During renaturation, an intermediate is populated, in which the longer of the two polypeptide chains forms a homodimer with a native-like subunit interface. The rate limiting step of renaturation is the association of the unfolded short chain with this dimer.

    In 2015, UNAIDS launched the 90-90-90 targets aimed at increasing the number of people infected with HIV to become aware of their status, access antiretroviral therapies and ultimately be virally suppressed. To achieve these goals, countries may need to scale up point-of-care (POC) testing in addition to strengthening central laboratory services. While decentralising testing increases patient access to diagnostics, it presents many challenges with regard to training and assuring the quality of tests and testing. To ensure synergies, the London School of Hygiene & Tropical Medicine held a series of consultations with countries with an interest in quality assurance and their implementing partners, and agreed on an external quality assessment (EQA) programme to ensure reliable results so that the results lead to the best possible care for HIV patients. As a result of the consultations, EQA International was established, bringing together EQA providers and implementers to develop a strategic plan for countries to establish national POC EQA programmes and to estimate the cost of setting up and maintaining the programme. With the dramatic increase in the number of proficiency testing panels required for thousands of POC testing sites across Africa, it is important to facilitate technology transfer from global EQA providers to a network of regional EQA centres in Africa for regional proficiency testing panel production. EQA International will continue to identify robust and cost-effective EQA technologies for quality POC testing, integrating novel technologies to support sustainable country-owned EQA programmes in Africa.

    The achievement of long duration, alternating current discharges on the tokamak IST-TOK requires a real-time plasma position control system. The plasma position determination based on magnetic probes system has been found to be inadequate during the current inversion due to the reduced plasma current. A tomography diagnostic has been therefore installed to supply the required feedback to the control system. Several tomographic methods are available for soft X-ray or bolo-metric tomography, among which the Cormack and Neural networks methods stand out due to their inherent speed of up to 1000 reconstructions per second, with currently available technology. This paper discusses the application of these algorithms on fusion devices while comparing performance and reliability of the results. It has been found that although the Cormack based inversion proved to be faster, the neural networks reconstruction has fewer artifacts and is more accurate.

    The aim of this study was to describe a study protocol that evaluates the effectiveness of the 'Home-but not Alone' educational programme delivered via a mobile health application in improving parenting outcomes. The development in mobile-based technology gives us the opportunity to develop an accessible educational programme that can be potentially beneficial to new parents. However, there is a scarcity of theory-based educational programmes that have incorporated technology such as a mobile health application in the early postpartum period. A randomized controlled trial with a two-group pre-test and post-test design. The data will be collected from 118 couples. Eligible parents will be randomly allocated to either a control group (receiving routine care) or an intervention group (routine care plus access to the 'Home-but not Alone' mobile health application. Outcome measures comprise of parenting self-efficacy, social support, parenting satisfaction and postnatal depression. Data will be collected at the baseline (on the day of discharge) and at four weeks postpartum. This will be an empirical study that evaluates a theory-based educational programme delivered via an innovative mobile health application on parental outcomes. Results from this study will enhance parenting self-efficacy, social support and parenting satisfaction, which may then reduce parental risks of postnatal depression. © 2016 John Wiley & Sons Ltd.

  9. Verbesserung der Symmetrie von Hirnaufnahmen entlang der Sagittalebene

    Ens, Konstantin; Wenzel, Fabian; Fischer, Bernd

    Die lokale Symmetrie von Hirnscans entlang der Sagittalebene zu ermitteln und zu modizifieren, ist für eine Reihe neurologischer Anwendungen interessant. Beispielsweise kann der voxelweise Vergleich von rechter und linker Hirnhälfte nur dann Aufschluss über die Lokalisierung von Läsionen geben, wenn durch Transformation ein Hirnscan eine möglichst hohe Symmetrie aufweist. Ein weiteres Anwendungsgebiet ist die Visualisierung von medialen Hirnschnitten, für die die Trennfläche beider Hirnhälfte möglichst eben sein sollte. Diese Arbeit stellt die Entwicklung eines Verfahrens vor, mit dessen Hilfe die Symmetrie von Hirnaufnahmen entlang der Sagittalebene verbessert werden kann. Dies geschieht unter Verwendung von aktiven Konturen, die mit Hilfe einer neuartigen Kostenfunktion gesteuert werden. Experimente am Ende der Arbeit mit strukturellen Kernspinaufnahmen demonstrieren die Leistungsfähigkeit des Verfahrens.

    A study was performed in order to develop the criteria for the selection of flow direction indicators for use in the Integrated Systems Tests (ISTs) of the 40 by 80/80 by 120 Foot Wind Tunnel System. The problems, requirements, and limitations of flow direction measurement in the wind tunnel were investigated. The locations and types of flow direction measurements planned in the facility were discussed. A review of current methods of flow direction measurement was made and the most suitable technique for each location was chosen. A flow direction vane for each location was chosen. A flow direction vane that employs a Hall Effect Transducer was then developed and evaluated for application during the ISTs.

  12. Formation of quasiparallel Alfven solitons

    The formation of quasi-parallel Alfven solitons is investigated through the inverse scattering transformation (IST) for the derivative nonlinear Schroedinger (DNLS) equation. The DNLS has a rich complement of soliton solutions consisting of a two-parameter soliton family and a one-parameter bright/dark soliton family. In this paper, the physical roles and origins of these soliton families are inferred through an analytic study of the scattering data generated by the IST for a set of initial profiles. The DNLS equation has as limiting forms the nonlinear Schroedinger (NLS), Korteweg-de-Vries (KdV) and modified Korteweg-de-Vries (MKdV) equations. Each of these limits is briefly reviewed in the physical context of quasi-parallel Alfven waves. The existence of these limiting forms serves as a natural framework for discussing the formation of Alfven solitons.

  13. Niederschlag

    Kunz, Michael; Mohr, Susanna; Werner, Peter C.

    Niederschlag kann in flüssiger Form als Niesel oder Regen oder in gefrorener, fester Form als Graupel, Hagel oder Schnee fallen. Durch die globale Erwärmung intensiviert sich der Wasserkreislauf, was zu einer Veränderung der Niederschlagsmuster führt. Außerdem ist zu erwarten, dass sich im Zuge des Klimawandels auch die Häufigkeit bestimmter Wetterlagen ändern wird, die das Niederschlagsgeschehen grundsätzlich bestimmen. Bereits heute ist in Deutschland eine Änderung der Niederschlagsaktivität zu beobachten. Das Kapitel beschäftigt sich neben den sommerlichen und winterlichen Starkniederschlagsereignissen auch mit Hagelereignissen und dem Schneefall. Neben einer Zusammenfassung der bereits beobachteten Änderungen dieser Niederschlagsformen in der Vergangenheit wird auch der Frage nachgegangen, inwieweit man für diese Ereignisse belastbare Aussagen für die Zukunft treffen kann.

    The purpose of this research project was to produce a well integrated set of tools for the support of numerical computation. The project entailed the specification, design and implementation of both a diversity of tools and an innovative tool integration mechanism. This large configuration of tightly integrated tools comprises an environment for numerical software development, and has been named Toolpack/IST (Integrated System of Tools). Following the creation of this environment in prototype form, the environment software was readied for widespread distribution by transitioning it to a development organization for systematization, documentation and distribution. It is expected that public release ofmore » Toolpack/IST will begin imminently and will provide a basis for evaluation of the innovative software approaches taken as well as a uniform set of development tools for the numerical software community.« less

    Limited research has explored how to best train caregivers to support their child with autism spectrum disorder (ASD) despite caregivers being well suited to promote generalization and maintenance of their child's skills in the natural environment. Children with ASD have been shown to benefit from social skill training, which is not always conducted in the natural context. This research examined the efficacy of behavioral skills training (BST) with, and without in situ training (IST), for teaching caregivers how to also use BST to support their child's context-specific social skills. Although caregivers met mastery criterion within BST sessions, their skills did not generalize to the natural environment until IST was introduced. The implications of the findings are discussed.

    Die Suche nach den Grundbausteinen der Materie und nach den Kräften, die zwischen ihnen wirken, ist das Forschungsgebiet der Hochenergiephysik. Mit immer größer werdenden Teilchenbeschleunigern erreicht man immer tiefer gehende Erkenntnisse und dringt dabei in Energiebereiche vor, wie sie kurz nach dem Urknall herrschten. Im Moment ist das Tevatron am Fermilab der energ piereichste Teilchenbeschleuniger der Welt mit einer Schwerpunktsenergie von √s = 1, 96 TeV. Um die bei diesen hohen Energien entstehende Anzahl von Teilchen zu messen, sind auch immer höher auflösende Detektoren nötig. Dem wurde dadurch Rechnung getragen, dass mit der Steigerung der Schwerpunktsenergie am Tevatron auch diemore » Detektoren DØ und CDF1) teilweise erneuert wurden.« less

  17. Mission Specific Platforms: Past achievements and future developments in European led ocean research drilling.

    Mission Specific Platform (MSP) expeditions are operated by the European Consortium for Ocean Research Drilling (ECORD). Each MSP expedition is unique within the Integrated Ocean Drilling Program (IODP). In order to complement the abilities of the JOIDES Resolution and the Chikyu, the ECORD Science Operator (ESO) must source vessels and technology suitable for each MSP proposal on a case-by-case basis. The result is that ESO can meet scientific requirements in a flexible manner, whilst maintaining the measurements required for the IODP legacy programme. The process of tendering within EU journals for vessels and technology means that the planning process for each MSP Expedition starts many years in advance of the operational phase. Involvement of proposal proponents from this early stage often leads to the recognition for technological research and development to best meet the scientific aims and objectives. One example of this is the planning for the Atlantis Massif proposal, with collaborative development between the British Geological Survey (BGS) and MARUM, University of Bremen, on suitable instruments for seabed drills, with the European Petrophysics Consortium (EPC) driving the development of suitable wireline logging tools that can be used in association with such seabed systems. Other technological developments being undertaken within the European IODP community include in-situ pressure sampling for gas hydrate expeditions, deep biosphere and fluid sampling equipment and CORK technology. This multi-national collaborative approach is also employed by ESO in the operational phase. IODP Expedition 302 ACEX saw vessel and ice management support from Russia and Sweden to facilitate the first drilling undertaken in Arctic sea ice. A review of MSP expeditions past, present and future reveal the significant impact of European led operations and scientific research within the current IODP programme, and also looking forward to the start of the new International Ocean Discovery Programme in October 2013. Key successes encompass technological development, operational procedures in sensitive areas and research into palaeoclimate and shoreline responses to sea level change amongst others. Increased operational flexibility in the new programme only serves to make the future an exciting one for ocean drilling in Europe.

    Micro-Opto-Electro-Mechanical Systems (MOEMS) could be key components in future generation of space instruments. In Earth Observation, Universe Observation and Planet Exploration, scientific return of the instruments must be optimized in future missions. MOEMS devices are based on the mature micro-electronics technology and in addition to their compactness, scalability, and specific task customization, they could generate new functions not available with current technologies. CNES has initiated a study with LAM and TAS for listing the new functions associated with several types of MEMS (programmable slits, programmable micro-diffraction gratings, micro-deformable mirrors). Instrumental applications are then derived and promising concepts are described.
