    This paper summarizes the experience with sex therapy in an in-patient ward for neurotics (N = 82), where it could be combined with interpersonally oriented group psychotherapy in a therapeutic community setting. Outcome data are compared with an out-patient form of sex therapy, used in several counseling centers (N = 111). The in-patient form of therapy had a success rate of 76% at completion of treatment and 52% after a follow-up period of 15 months. The out-patient therapy was successful in 71% but no follow-up was carried out. Almost 50% of the couples who originally started therapy dropped out. Three illustrative successful cases are described. PMID:7205970

  2. The assessment and management of pain in an orthopaedic out-patient setting: A case study.

    The management of pain is an important aspect of an orthopaedic nurse's role. The aim of this paper is to use an individual case study to demonstrate the role of an out-patient orthopaedic nurse in the identification, assessment and management of pain. This paper describes how pain was identified and managed for a patient in the orthopaedic outpatient department, highlighting that pain and its management are not isolated to the in-patient setting. The case study illustrates the importance of recognising pain and taking into account the numerous factors that can influence pain perception. The assessment of an individual patient's pain led to obtaining help from the Acute Pain Team which led to improvement in the patient's pain management and quality of life. The nursing team reflected and discussed the issues identified by this case study which led to changes in practice being introduced. This has resulted in an increased knowledge of and confidence in pain management within the nursing team and development and improvement of pain management practice within the orthopaedic out-patient department.

    The goal of this current study was to test divided attention abilities of a group adults with autism and normal intellectual functioning, treated in a residential setting versus those treated in an out-patient setting. Both groups were compared with a control group using the Sternberg (1969) reaction time paradigm. It appeared that the in-patient group suffered from a divided attention deficit compared to a norm group. The patients treated in an out-patient setting scored in between the norm group and the in-patient group. Findings are discussed with respect to the relevance for the day to day clinical practice.

    According to the state-of-the-art in health psychology and psycho-oncology, a cancerous disease, as well as the accompanying medical treatments, is a source ofintense emotional stress. As feelings of insecurity and anxiety are likely to induce negative effects on immune defences, those effects may overlap with the cancerous disease and complicate its evolution. As arts therapies tend to favour the imaginary and symbolic elaboration of the tensions of daily life, as well as the re appropriation of one's body and personal history, different artistic mediations may occupy an important function in the psychological follow-up of the patient. Following an exploratory study in a hospital, we carried out an action-research in an out-patient setting during six moths. The arts therapeutic treatment comprehended alternatively drawing and writing sessions while listening to music, opening tracks for a thorough verbal elaboration. The evaluation was based on psychometric scales (HADS and MDBF), rating scales for the pictorial and literary production and a semi-structured interview. According to the results of the quantitative analyses, based on non parametric statistical procedures for small groups and non metric data, as well as to the qualitative content analyses, arts therapies could become a valuable treating measure within a multidisciplinary bio-psycho-social approach.

    Purpose The patient-centered approach to health care does not seem to be sufficiently developed in the Italian context, and is still characterized by the biomedical model. In addition, there is a lack of validated outcome measures to assess outpatient experience as an aspect common to a variety of settings. The current study aimed to evaluate the factorial validity, reliability, and invariance across sex of the Health Services OutPatient Experience (HSOPE) questionnaire, a short ten-item measure of patient-centeredness for Italian adult outpatients. The rationale for unidimensionality of the measure was that it could cover global patient experience as a process common to patients with a variety of diseases and irrespective of the phase of treatment course. Patients and methods The HSOPE was compiled by 1,532 adult outpatients (51% females, mean age 59.22 years, standard deviation 16.26) receiving care in ten facilities at the Santa Maria alle Scotte University Hospital of Siena, Italy. The sample represented all the age cohorts. Twelve percent were young adults, 57% were adults, and 32% were older adults. Exploratory and confirmatory factor analyses were conducted to evaluate factor structure. Reliability was evaluated as internal consistency using Cronbach’s α. Factor invariance was assessed through multigroup analyses. Results Both exploratory and confirmatory analyses suggested a clearly defined unidimensional structure of the measure, with all the ten items having salient loadings on a single factor. Internal consistency was excellent (α=0.95). Indices of model fit supported a single-factor structure for both male and female outpatient groups. Young adult outpatients had significantly lower scores on perceived patient-centeredness relative to older adults. No significant difference emerged on patient-centeredness between male and female outpatients. Conclusion The HSOPE questionnaire seemed to be a tool with high acceptability and excellent psychometric

    Aims To study the 1-year outcome and to analyse predictors of outcome of a cohort of adolescent girls with anorexia nervosa (AN) or restrictive eating disorders not otherwise specified (EDNOSr) treated as out-patients in a family-based programme at a specialized eating disorder service. To calculate the incidence of anorexia nervosa among treatment-seeking girls younger than 18 in Uppsala County from 2004 to 2006. Methods A total of 168 female patients were offered treatment, and 141 were followed-up 1 year after starting treatment, 29 with AN and 112 with EDNOSr. Results Of the 29 girls who initially had AN, 6 (20%) had a good outcome and were free of any form of eating disorder at follow-up; only 1 (3%) had AN. Of the patients with EDNOSr, 54 (48%) had a good outcome and were free of eating disorders. Three (3%) had a poor outcome and had developed AN. The incidence of AN was 18/100,000 person-years in girls younger than 12 and 63/100,000 in girls younger than 18. Conclusion Restrictive eating disorders, including AN, in children and adolescents can be successfully treated in a family-based specialized out-patient service without in-patient care.

    Patients receiving chronic hemodialysis (CHD) are among the most vulnerable to infections caused by multidrug-resistant organisms (MDRO), which are associated with high rates of morbidity and mortality. Current guidelines to reduce transmission of MDRO in the out-patient dialysis unit are targeted at patients considered to be high-risk for transmitting these organisms: those with infected skin wounds not contained by a dressing, or those with fecal incontinence or uncontrolled diarrhea. Here, we hypothesize that targeting patients receiving antimicrobial treatment would more effectively reduce transmission and acquisition of MDRO. We also hypothesize that environmental contamination plays a role in the dissemination of MDRO in the dialysis unit. To address our hypotheses, we built an agent-based model to simulate different treatment strategies in a dialysis unit. Our results suggest that reducing antimicrobial treatment, either by reducing the number of patients receiving treatment or by reducing the duration of the treatment, markedly reduces overall colonization rates and also the levels of environmental contamination in the dialysis unit. Our results also suggest that improving the environmental decontamination efficacy between patient dialysis treatments is an effective method for reducing colonization and contamination rates. These findings have important implications for the development and implementation of future infection prevention strategies. PMID:27195984

    Few data are currently available on the prevalence and associated characteristics of anxiety disorders in psychiatric out-patients in France, in particular in the private health-care. However, this represents one of the principal systems of care for patients suffering from anxiety disorders, with a possible direct access and several types of treatments available (pharmacotherapy but also different kinds of psychotherapy). The aim of our study was to describe the prevalence of anxiety disorders in a large sample of patients consulting in the private sector, and in addition to study the comorbidity, the severity of the disorders, their consequences on quality of life and health care consumption. The studied patients were included and assessed by 501 psychiatrists from all the country, at the time of a first visit. Inclusions were to be made in a consecutive way, but with the exclusion of psychotic disorders and dementia. A sample of 1 955 patients was obtained, and all subjects had a standardized diagnostic assessment with the Mini International Neuropsychiatric Interview (MINI) and with various dimensional scales of symptomatology severity, quality of life, and health care consumption. On the whole, at least one current anxiety disorder was found in 64.3% of the patients, while 55% had a depressive disorder. Individually, the prevalence rates are 29.4% for generalized anxiety disorder, 25.9% for agoraphobia, 19.2% for panic disorder, 15.3% for social phobia, 11.4% for obsessive-compulsive disorder, and 5.4% for post-traumatic stress disorder (PTSD). A history of suicide attempts was found in 12-20% of patients, and an elevated suicide risk was found for example in 25% of PTSD patients. The scores of the symptomatic scales, adaptation and quality of life measure show a very significant anxious symptomatology, with serious functional consequences. Approximately 75% of patients had another medical consultation during the three previous months, and 9% have been

    Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen, and colonisation with this organism can result in localised or systemic infections which may be fatal. One hundred in-patients admitted to a London teaching hospital and 100 out-patients attending prosthetic dentistry clinics were recruited into this study. Of the 100 out-patients, 27 % harboured S. aureus on their dentures, compared to 33 % of in-patients. Only one out-patient had MRSA colonising their dentures whereas 12 % of the in-patients harboured MRSA. The median total bacterial count of the denture plaque samples was 6.2 × 10(7) cfu/sample and 6.9 × 10(7) cfu/sample for the out-patient and in-patient populations, respectively. In most instances, where present, S. aureus comprised less than 1 % of the total viable denture microbiota. Phage typing demonstrated that EMRSA-15 and non-typeable strains were harboured on dentures. The results of this study have revealed that dentures are a potential reservoir of MRSA and so account should be taken of these findings when planning decontamination procedures for elimination of this pathogen.

    A randomised controlled trial was used to evaluate a theory-based health promotion intervention. The intervention, a healthy living booklet, was designed to promote healthy eating and physical activity amongst people aged over 65 years attending hospital out-patient clinics. The booklet employed persuasive arguments targeting the most proximal cognitive antecedents of behaviour specified by the theory of planned behaviour, as well as goal setting prompts. Participants (N = 252, average age=82) were randomly allocated to a control (patient satisfaction questionnaire) or intervention (healthy living booklet) group. Cognitions and behaviour were measured pre-intervention and at a two week follow up. The intervention group made significantly higher gains in perceived behavioural control, intention and behaviour for both target behaviours, suggesting that the intervention was successful. Sixty three of those invited to set goals to eat more healthily (e.g., "to eat five portions of fruit and vegetables a day") did so, and 67% of those who set such goals reported 100% success in acting on them. By contrast, only 34% of intervention participants set an activity goal (e.g., "a five minute walk everyday"), and only 51% reported 100% success in enacting these goals. Results suggest that the observed behavioural effects of the healthy eating booklet could be attributed to goal setting as well as changes in perceived behavioural control and intention.

    This study aims to assess the incidence rate of Pteropine orthreovirus (PRV) infection in patients with acute upper respiratory tract infection (URTI) in a suburban setting in Malaysia, where bats are known to be present in the neighborhood. Using molecular detection of PRVs directly from oropharyngeal swabs, our study demonstrates that PRV is among one of the common causative agents of acute URTI with cough and sore throat as the commonest presenting clinical features. Phylogenetic analysis on partial major outer and inner capsid proteins shows that these PRV strains are closely related to Melaka and Kampar viruses previously isolated in Malaysia. Further study is required to determine the public health significance of PRV infection in Southeast Asia, especially in cases where co-infection with other pathogens may potentially lead to different clinical outcomes.

    Case: A shy, depressed 30 year old male discussed his frequent ego-syntonic indoor prostitution consumption in small peer groups. Several distinctive non-sexual functions of this paid sex habit were identified. Design and method: The patient had 40 hourly psychiatric sessions in the private practice setting over 14 months. The Arizona Sexual Experience Scale was applied to compare the subjective appraisal of both paid sex and sex in a relationship. The informal Social Atom elucidates social preferences and the Operationalized Psychodynamic Diagnostic-procedure was applied to describe a dominant relationship pattern. Results: The paid sex consumption functioned as a proud male life style choice to reinforce the patients fragile identity. The effect on self esteem was a release similar to his favorite past-time of kick-boxing. With paid sex asserted as a group ritual, it was practiced even with frequent erectile dysfunction and when sex with a stable romantic partner was more enjoyable and satisfying. The therapeutic attitude of the female psychiatrist, with her own ethical values, is put in to context with two opposing theories about prostitution: the ‘Sex-Work-model’ and the ‘Oppression-model’. The therapist’s reaction to the patients’ information was seen as a starting point to understanding the intrapsychic function of paid sex as a coping mechanism against depressive feelings. Conclusions: Exploring and understanding prostitution consumption patterns in young men can benefit the treatment of psychiatric disorders in the private practice setting. It is the psychiatrists task to investigate the patients hidden motives behind paid sex use to help patients achieve a greater inner and relational freedom. PMID:24627772

    Non-compliance has received significant attention in medicine, yet few studies have examined its correlates in autologous hematopoietic SCT (AHSCT) patients. This study examined predictors of non-compliance in a sample of 151 AHSCT patients treated in an outpatient setting. Before AHSCT, participants completed a validated measure of mood and retrospective chart reviews were conducted to assess non-compliance during AHSCT, defined as refusal of oral hygiene, prescribed exercise programs, oral nutrition and/or prescribed medications. We found 121 patients (80%) were non-compliant with an aspect of the AHSCT regimen on 1 or more days; mean percentage of non-compliant days was 16.6 (s.d. 15.6). Men were more likely than women to be non-compliant (P<0.05); as were participants with an elevated depression score (P<0.05). Stepwise regression models identified significant predictors of non-compliance: gender, depression, global distress and nausea and vomiting severity (P-values all <0.01). Further analysis revealed that the interaction of the psychological variables with gender was a more robust predictor of non-compliance (P<0.001). For outpatient AHSCT, our findings suggest the need to broaden conceptualizations of risk factors for non-compliance and the importance of assessing patient barriers to compliance to ensure optimal treatment outcome.

    The objective of this paper was to determine whether the presence of more vs. fewer anxious symptom features, at baseline, are associated with other clinical features and treatment outcomes in out-patients with major depressive disorder (MDD). This single-blind, randomized trial enrolled 665 MDD out-patients to compare the efficacy of two antidepressant medication combinations against escitalopram after 12-wk acute treatment and follow-up (total 28 wk). The sample was divided into those with greater (vs. fewer) anxiety features using the anxiety/somatization subscale of the baseline 17-item Hamilton Rating Scale for Depression. Baseline sociodemographic and clinical features, treatment features and outcomes compared these two groups. Overall, 74.7% of participants met the threshold for 'anxious features'. They were more likely to be female, have other concurrent anxiety disorders, more severe depression, more lethargic and melancholic features and poorer cognitive and physical functioning, quality of life and work and social adjustment. In acute treatment, participants with anxious features received comparatively higher doses of mirtazapine and venlafaxine and reported more side-effects. The groups with and without anxious features did not differ in treatment outcomes and side-effect burden. Despite being associated with a distinct clinical profile, baseline anxious features were not clinically useful in predicting acute treatment outcomes or differential treatment response.

    A comparative study of amoxycillin and pivmecillinam was performed on 298 out-patients with acute urinary tract infection, receiving either 375 mg amoxycillin three times daily or 400 mg pivmecillinam three times daily. The primary cure rate was 90% in the pivmecillinam group compared to 82% in the amoxycillin group. Resistant enterobacteriaceae emerged in approximately 5% of patients receiving amoxycillin but not after treatment with pivmecillinam. No serious side effects were observed in patients receiving picmecillinam and the tolerance was generally good. Upper gastrointestinal side effects were more frequent in the pivmecillinam group whereas lower gastrointestinal side effects predominated in the amoxycillin group. 200 mg pivmecillinam three times daily compared with 400 mg three times daily showed no differences in cure rate and side effects were lower (11% compared to 19%).

    The aim of this study was to describe and analyze the patterns of radiation exposure of contacts of Sudanese patients treated with radioactive 131I on an out-patient basis and post discharge after high dose 131I therapy, and also to compare the family members' results with dose constraints proposed by the European Commission (EC). Thermoluminiscent dosimeters (Model TLD-100 H) were used to estimate the effective doses for 40 family members of fifteen patients treated with 131I. The family members wore a TLD in front of the chest for 10 days. The effective dose ranged from 0.23 to 6.74 mSv (mean 1.75 mSv). These findings may be considered when establishing new national guidelines concerning radiation protection and release of patients after a treatment with radioiodine therapy.

    Background: Reproductive tract infections are public health problems in women of reproductive age and can result in serious consequences if not treated. Aims: To determine the prevalence and causes of reproductive tract infections among in-patients and out-patients attending a tertiary health institution in Benin City. The antimicrobial susceptibility profiles of bacterial agents will also be determined. Patients and Methods: High vaginal swabs or endocervical swabs and blood were collected from 957 patients consisting of 755 out-patients and 202 in-patients. The swabs were processed and microbial isolates identified using standard technique. Disc susceptibility tests were also performed on microbial isolates. The blood samples were used for serological diagnosis of syphilis. Results: There was no significant difference in the prevalence of female reproductive tract infections between in-patients (52.48%) and out-patients (47.02%), although in-patients showed a significantly higher risk of developing mixed infections (in-patients vs. out-patients; 34.91% vs. 22.25%, OR = 1.873 95% CI = 1.169, 3.001; P = 0.01). Candida albicans was the most prevalent etiologic agent among out-patients studied while Staphylococcus aureus was the most prevalent etiologic agent among in-patients. Trichomonas vaginalis was observed only among out-patients. Ceftriaxone, ciprofloxacin and ofloxacin were the most active antibacterial agents. Syphilis was not detected in any patient. Conclusion: An overall prevalence of 48.17% of female reproductive tract infection was observed among the study population. Although there was no significant difference between in-patients and out-patients, in-patients appeared to have 1-3-fold increase risk of developing mixed infections. The most prevalent etiologic agent differs between in-patients and out-patients. Despite the high activity of ceftriaxone, ciprofloxacin and ofloxacin against bacterial isolates from both in-patients and out-patients, prudent

    All patients who presented to our Accident & Emergency Department over a 6-month period with an acute knee injury were randomly assigned to receive either immediate physiotherapy or not prior to further follow up at an out-patient clinic. Patients with trivial injuries not requiring follow up and patients with severe injuries requiring immediate admission were excluded from the study. Patients not immediately referred for physiotherapy could be referred if this was thought necessary at later follow up. There was no statistical difference in the number of outpatient follow up appointments or the length of time to discharge from the clinic between the groups. Those patients referred for physiotherapy immediately had a significantly greater number of total attendances at the physiotherapy department. However more patients in the 'no physiotherapy' group ultimately required arthroscopy for suspected meniscal injury. We conclude that a blanket referral of all acute knee injury patients is unjustified and wasteful of resources. However physiotherapy may be indicated in patients initially suspected of having meniscal injury. PMID:2099163

    Skin infections are a common cause for dermatological consultations in the paediatric setting. A review is presented of the clinical manifestations, diagnosis and treatment of the main bacterial skin infections, as well as the diagnosis and treatment of super-infected puncture and bite wounds. The most prevalent bacteria in skin infections are Staphylococcus aureus and Streptococcus pyogenes. Treatment is usually empirical, since microbiological studies are only recommended under certain circumstances or lack of improvement with common therapies. Superficial skin infections can be treated with local antiseptics or antibiotics (mupirocin or fusidic acid). Systemic treatment is usually reserved for patients with extensive or severe disease or with other risk factors. Systemic treatment depends on the suspected infecting bacteria, with penicillin, amoxicillin, amoxicillin-clavulanic acid and first or second generation cephalosporin being the most frequently used drugs. Due to the low incidence of community-acquired methicillin-resistant infection by S. aureus in Spain, the use of clindamycin or co-trimoxazole is only recommended after severe disease, relapses or a clear epidemiological background.

    As a strong component in patient healing, interpersonal connection in the psychiatric/mental health setting can threaten nurses' health. Participant observation on four behavioral health and addiction units revealed a process of connecting with patients' emotional pain, delineating strategies applicable to nurses' multiple world views and practice styles. Findings from 12 nurses highlighted connectedness as a process and personal decision that, with self-awareness and individualized self-protective/self-separating strategies, can enhance patient healing as well as nurse satisfaction and growth. The evolved model may help nurses ease emotional labor, combat compassion fatigue, enhance performance, and preserve their self in today's complex acute care setting. PMID:23301568

    The contribution of psychological disorders to the burden of skin disease has been poorly explored, and this is a large-scale study to ascertain the association between depression, anxiety, and suicidal ideation with various dermatological diagnoses. This international multicenter observational cross-sectional study was conducted in 13 European countries. In each dermatology clinic, 250 consecutive adult out-patients were recruited to complete a questionnaire, reporting socio-demographic information, negative life events, and suicidal ideation; depression and anxiety were assessed with the Hospital Anxiety and Depression Scale. A clinical examination was performed. A control group was recruited among hospital employees. There were 4,994 participants––3,635 patients and 1,359 controls. Clinical depression was present in 10.1% patients (controls 4.3%, odds ratio (OR) 2.40 (1.67–3.47)). Clinical anxiety was present in 17.2% (controls 11.1%, OR 2.18 (1.68–2.82)). Suicidal ideation was reported by 12.7% of all patients (controls 8.3%, OR 1.94 (1.33–2.82)). For individual diagnoses, only patients with psoriasis had significant association with suicidal ideation. The association with depression and anxiety was highest for patients with psoriasis, atopic dermatitis, hand eczema, and leg ulcers. These results identify a major additional burden of skin disease and have important clinical implications. PMID:25521458

  7. Household cost of out-patient treatment of Buruli ulcer in Ghana: a case study of Obom in Ga South Municipality

    PubMed Central

    2013-01-01

    Background The economic burden of diseases has become increasingly relevant to policy makers as healthcare expenditure keep rising in the face of limited and competing resources. Buruli ulcer (BU), a neglected but treatable tropical disease caused by Mycobacterium ulcerans, the only known environmental mycobacterium is capable of causing long term disability when left untreated. However, most BU studies have tended to focused on its bacteriology, epidemiology, entomology and other social determinants to the neglect of its economic evaluation. This paper reports estimated the household economic costs of BU and describe the intangible cost suffered by BU patients in an endemic area. Methods Retrospective one year cost data was used. A total of 63 confirmed BU cases were randomly sampled for the study. Economic cost and cost burden of BU were estimated. Sensitivity analysis was conducted to test the robustness of the cost estimates. Intangible cost measured stigmatization, pain, functional limitation and social isolation of children. Results The annual total household economic cost was US$35,915.98, of which about 65% was cost incurred by children with a mean cost of US$521.04. The mean annual household cost was US$570.09. The direct cost was 96% of the total cost. Non-medical cost accounts for about 97% of the direct cost with a mean cost of US$529.27. The mean medical cost was US$18.94. The main cost drivers of the household costs were transportation (78%) and food (12%). Caregivers and adult patients lost a total of 535 productive days seeking care, which gives an indirect cost valued at US$1,378.67 with a mean of US$21.88. A total of 365 school days (about 1 year) were lost by 19 BU patients (mean, 19.2 days). Functional loss and pain were low, and stigma rated moderate. Most children suffering from BU (84%) were socially isolated. Conclusion Household cost burden of out-patient BU ulcer treatment was high. Household cost of BU is therefore essential in the

    Testing urine specimens obtained at surprise visits to the home or at routine clinic attendance is an established procedure in the supervision of patients receiving ambulatory chemotherapy for pulmonary tuberculosis. A urine test service was set up in 9 East African centres, involving 37 staff members (most with limited training) who conducted a simple paper test for isoniazid. Analysis of the results obtained yielded an unbelievably high proportion of positive results, indicating that the testing system, as organized, had been a failure. Special investigations were therefore carried out into the reasons for this.Over-reading of test results, incorrect performance of the test, and, in 1 centre, dishonest recording were found as explanations. Discussing the implications of their findings, the authors stress the importance of close supervision at all stages of tuberculosis-control procedures in the field, no matter how simple; and they point out with reference to urine testing that, even if a centralized testing system, involving a sensitive test method and quality control, were to be set up in regional laboratories, adequate supervision at all stages would be essential.

    SETS is used for symbolic manipulation of Boolean equations, particularly the reduction of equations by the application of Boolean identities. It is a flexible and efficient tool for performing probabilistic risk analysis (PRA), vital area analysis, and common cause analysis. The equation manipulation capabilities of SETS can also be used to analyze noncoherent fault trees and determine prime implicants of Boolean functions, to verify circuit design implementation, to determine minimum cost fire protection requirements for nuclear reactor plants, to obtain solutions to combinatorial optimization problems with Boolean constraints, and to determine the susceptibility of a facility to unauthorized access through nullification of sensors in its protection system.

    Understanding relationships between sets is an important analysis task that has received widespread attention in the visualization community. The major challenge in this context is the combinatorial explosion of the number of set intersections if the number of sets exceeds a trivial threshold. In this paper we introduce UpSet, a novel visualization technique for the quantitative analysis of sets, their intersections, and aggregates of intersections. UpSet is focused on creating task-driven aggregates, communicating the size and properties of aggregates and intersections, and a duality between the visualization of the elements in a dataset and their set membership. UpSet visualizes set intersections in a matrix layout and introduces aggregates based on groupings and queries. The matrix layout enables the effective representation of associated data, such as the number of elements in the aggregates and intersections, as well as additional summary statistics derived from subset or element attributes. Sorting according to various measures enables a task-driven analysis of relevant intersections and aggregates. The elements represented in the sets and their associated attributes are visualized in a separate view. Queries based on containment in specific intersections, aggregates or driven by attribute filters are propagated between both views. We also introduce several advanced visual encodings and interaction methods to overcome the problems of varying scales and to address scalability. UpSet is web-based and open source. We demonstrate its general utility in multiple use cases from various domains. PMID:26356912

    The Set Equation Transformation System (SETS) is used to achieve the symbolic manipulation of Boolean equations. Symbolic manipulation involves changing equations from their original forms into more useful forms - particularly by applying Boolean identities. The SETS program is an interpreter which reads, interprets, and executes SETS user programs. The user writes a SETS user program specifying the processing to be achieved and submits it, along with the required data, for execution by SETS. Because of the general nature of SETS, i.e., the capability to manipulate Boolean equations regardless of their origin, the program has been used for many different kinds of analysis.

    The present study examined the organization of preparatory processes that underlie set switching and, more specifically, switch costs. On each trial, subjects performed one of two perceptual judgment tasks, color or shape discrimination. Subjects also responded with one of two different response sets. The task set and/or the response set switched from one to the other after 2-6 repeated trials. Response set, task set, and double set switches were performed in both blocked and randomized conditions. Subjects performed with short (100-msec) and long (800-msec) preparatory intervals. Task and response set switches had an additive effect on reaction times (RTs) in the blocked condition. Such a pattern of results suggests a serial organization of preparatory processes when the nature of switches is predictable. However, task and response set switches had an underadditive effect on RTs in the random condition when subjects performed with a brief cue-to-target interval. This pattern of results suggests overlapping task and response set preparation. These findings are discussed in terms of strategic control of preparatory processes in set switching. PMID:12921431

  16. Acronical Risings and Settings

    Hockey, Thomas A.

    2012-01-01

    A concept found in historical primary sources, and useful in contemporary historiography, is the acronical rising and setting of stars (or planets). Topocentric terms, they provide information about a star's relationship to the Sun and thus its visibility in the sky. Yet there remains ambiguity as to what these two phrases actually mean. "Acronical” is said to have come from the Greek akros ("point,” "summit,” or "extremity") and nux ("night"). While all sources agree that the word is originally Greek, there are alternate etymologies for it. A more serious difficulty with acronical rising and setting is that there are two competing definitions. One I call the Poetical Definition. Acronical rising (or setting) is one of the three Poetical Risings (or Settings) known to classicists. (The other two are cosmical rising/setting, discussed below, and the more familiar helical rising/setting.) The term "poetical" refers to these words use in classical poetry, e. g., that of Columella, Hesiod, Ovid, Pliny the Younger, and Virgil. The Poetical Definition of "acronical” usually is meant in this context. The Poetical Definition of "acronical” is as follows: When a star rises as the Sun sets, it rises acronically. When a star sets as the Sun sets, it sets acronically. In contrast with the Poetical Definition, there also is what I call the Astronomical Definition. The Astronomical Definition is somewhat more likely to appear in astronomical, mathematical, or navigational works. When the Astronomical Definition is recorded in dictionaries, it is often with the protasis "In astronomy, . . . ." The Astronomical Definition of "acronical” is as follows: When a star rises as the Sun sets, it rises acronically. When a star sets as the Sun rises, it sets acronically. I will attempt to sort this all out in my talk.

Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) in chaos theory, (ii) for paradoxical decompositions of solid three-dimensional objects, (iii) in the theory of effective computability (Church-Turing thesis) related to the possible “solution of supertasks,” and (iv) for weak solutions. Several approaches to set theory and their advantages and disadvatages for physical applications are discussed: Canlorian “naive” (i.e., nonaxiomatic) set theory, contructivism, and operationalism. In the author's opinion, an attitude of “suspended attention” (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same time, physicists should be open to “bizarre” or “mindboggling” new formalisms, which need not be operationalizable or testable at the lime of their creation, but which may successfully lead to novel fields of phenomenology and technology.

    2014-03-01

    In models of QM over finite fields (e.g., Schumacher's ``modal quantum theory'' MQT), one finite field stands out, Z2, since Z2 vectors represent sets. QM (finite-dimensional) mathematics can be transported to sets resulting in quantum mechanics over sets or QM/sets. This gives a full probability calculus (unlike MQT with only zero-one modalities) that leads to a fulsome theory of QM/sets including ``logical'' models of the double-slit experiment, Bell's Theorem, QIT, and QC. In QC over Z2 (where gates are non-singular matrices as in MQT), a simple quantum algorithm (one gate plus one function evaluation) solves the Parity SAT problem (finding the parity of the sum of all values of an n-ary Boolean function). Classically, the Parity SAT problem requires 2n function evaluations in contrast to the one function evaluation required in the quantum algorithm. This is quantum speedup but with all the calculations over Z2 just like classical computing. This shows definitively that the source of quantum speedup is not in the greater power of computing over the complex numbers, and confirms the idea that the source is in superposition.

    We present a state property called congruence and show how it can be used to demonstrate commutivity of instructions in a modern load-store architecture. Our analysis is particularly important in pipelined microprocessors where instructions are frequently reordered to avoid costly delays in execution caused by hazards. Our work has significant implications to safety and security critical applications since reordering can easily change the meaning and an instruction sequence and current techniques are largely ad hoc. Our work is done in a mechanical theorem prover and results in a set of trustworthy rules for instruction reordering. The mechanization makes it practical to analyze the entire instruction set.

    This paper presents a new concept of complex intuitionistic fuzzy set (CIFS) which is generalized from the innovative concept of a complex fuzzy set (CFS) by adding the non-membership term to the definition of CFS. The novelty of CIFS lies in its ability for membership and non-membership functions to achieve more range of values. The ranges of values are extended to the unit circle in complex plane for both membership and non-membership functions instead of [0, 1] as in the conventional intuitionistic fuzzy functions. We define basic operations namely complement, union, and intersection on CIFSs. Properties of these operations are derived.

    Recording setting changes within an accelerator facility provides information that can be used to answer questions about when, why, and how changes were made to some accelerator system. This can be very useful during normal operations, but can also aid with security concerns and in detecting unusual software behavior. The Set History System (SHS) is a new client-server system developed at the Collider-Accelerator Department of Brookhaven National Laboratory to provide these capabilities. The SHS has been operational for over two years and currently stores about IOOK settings per day into a commercial database management system. The SHS system consists of a server written in Java, client tools written in both Java and C++, and a web interface for querying the database of setting changes. The design of the SHS focuses on performance, portability, and a minimal impact on database resources. In this paper, we present an overview of the system design along with benchmark results showing the performance and reliability of the SHS over the last year.

  15. Probabilistic Open Set Recognition

    NASA Astrophysics Data System (ADS)

    Jain, Lalit Prithviraj

    Real-world tasks in computer vision, pattern recognition and machine learning often touch upon the open set recognition problem: multi-class recognition with incomplete knowledge of the world and many unknown inputs. An obvious way to approach such problems is to develop a recognition system that thresholds probabilities to reject unknown classes. Traditional rejection techniques are not about the unknown; they are about the uncertain boundary and rejection around that boundary. Thus traditional techniques only represent the "known unknowns". However, a proper open set recognition algorithm is needed to reduce the risk from the "unknown unknowns". This dissertation examines this concept and finds existing probabilistic multi-class recognition approaches are ineffective for true open set recognition. We hypothesize the cause is due to weak adhoc assumptions combined with closed-world assumptions made by existing calibration techniques. Intuitively, if we could accurately model just the positive data for any known class without overfitting, we could reject the large set of unknown classes even under this assumption of incomplete class knowledge. For this, we formulate the problem as one of modeling positive training data by invoking statistical extreme value theory (EVT) near the decision boundary of positive data with respect to negative data. We provide a new algorithm called the PI-SVM for estimating the unnormalized posterior probability of class inclusion. This dissertation also introduces a new open set recognition model called Compact Abating Probability (CAP), where the probability of class membership decreases in value (abates) as points move from known data toward open space. We show that CAP models improve open set recognition for multiple algorithms. Leveraging the CAP formulation, we go on to describe the novel Weibull-calibrated SVM (W-SVM) algorithm, which combines the useful properties of statistical EVT for score calibration with one-class and binary

  16. Local anesthesia in reduction mastoplasty for out-patient surgery.

    PubMed

    Mottura, A A

    1992-01-01

    To perform a breast reduction under local anesthesia we need a large amount of anesthetic with lasting effects. For this I use a solution of 25 cc of lidocaine, 25 cc of bupivacaine, and 1 cc of epinephrine in 350 cc of saline solution. The bupivacaine allows a 4-6-hour operation. Once the breast is infiltrated, a great amount of anesthetic is lost in the incision, in the dissection, and in the resected tissue. Thus, a low dose remains subcutaneously to be metabolized by the liver. The serum lidocaine levels are low during these operations, as demonstrated by fluorescence polarization immunoassay. Under analgesic sedation the submammary sulcus and the retroglandular space are infiltrated, blocking the perforants of the intercostal nerves, under the areola, beneath the skin where the incision is made and where the areola is placed. This procedure has been applied to many techniques of breast reduction by modifying the infiltration under the incision lines. For hypertrophy up to 1000 g, 200-300 cc of anesthetic solution is used for both breasts at one stage, while for gigantomastia, about 400 cc of anesthetic is used, infiltrating and reducing one after the other. As the blood loss is minimal and the recovery very fast, with an appropriate adhesive bandage and a "soutien," the patient could be discharged in the afternoon. Our experience includes 94 reduction mastoplasties with local anesthesia, and also 74 other mastoplasties with equally good results. There were no patient complaints and, in general, they felt very comfortable, awakening without pain or side effects. PMID:1414655

    Interventions by the pharmacists have always been considered as a valuable input by the health care community in the patient care process by reducing the medication errors, rationalizing the therapy and reducing the cost of therapy. The primary objective of this study was to determine the number and types of medication errors intervened by the dispensing pharmacists at OPD pharmacy in the Khoula Hospital during 2009 retrospectively. The interventions filed by the pharmacists and assistant pharmacists in OPD pharmacy were collected. Then they were categorized and analyzed after a detailed review. The results show that 72.3% of the interventions were minor of which 40.5% were about change medication order. Comparatively more numbers of prescriptions were intervened in female patients than male patients. 98.2% of the interventions were accepted by the prescribers reflecting the awareness of the doctors about the importance of the pharmacy practice. In this study only 688 interventions were due to prescribing errors of which 40.5% interventions were done in changing the medication order of clarifying the medicine. 14.9% of the interventions were related to administrative issues, 8.7% of the interventions were related to selection of medications as well as errors due to ignorance of history of patients. 8.2% of the interventions were to address the overdose of medications. Moderately significant interventions were observed in 19.4% and 7.5% of them were having the impact on major medication errors. Pharmacists have intervened 20.8% of the prescriptions to prevent complications, 25.1% were to rationalize the treatment, 7.9% of them were to improve compliance. Based on the results we conclude that the role of pharmacist in improving the health care system is vital. We recommend more number of such research based studies to bring awareness among health care professionals, provide solution to the prescription and dispensing problems, as it can also improve the documentation system, emphasize the importance of it, reduce prescribing errors, and update the knowledge of pharmacists and other health care professionals.

DISC employs a new parallel instruction set, an Early Binding and Scheduling data tagging scheme, and a distributed control mechanism to explore a software dataflow control method in a multiple-functional unit system. With zero system control overhead, multiple instructions are executed in parallel and/or out of order at the highest speed of n instructions/cycle, where n is the number of functional units. The quantitative simulation result indicates that a DISC system with 16 functional units can deliverer a maximal 7.7X performance speedup over a single functional-unit system at the same clock speed. Exploring a new parallel instruction set and distributed control mechanism, DISC represents three major breakthroughs in the domain of fine-grained parallel processing: (1) Fast multiple instruction issuing mechanism; (2) Parallel and/or out-of-order execution; (3) Software dataflow control scheme.

The following diagnostics are now in use: diamagnetic loops, a multichord microwave interferometer, Langmuir and emissive probes, pick-up loops, and secondary-emission detectors. End-loss diagnostics include net current detector arrays, Faraday cup arrays, swept particle analyzer arrays, and calorimetry. Light-emission measurements are made in the visible and VUV regions. A multichord fiber-optic array for plasma position detection is also used. In addition, a three-channel charge exchange analyzer, a hard x-ray system, and fast pressure gauges are available.

  2. Index Sets and Vectorization

    SciTech Connect

    Keasler, J A

    2012-03-27

    Vectorization is data parallelism (SIMD, SIMT, etc.) - extension of ISA enabling the same instruction to be performed on multiple data items simultaeously. Many/most CPUs support vectorization in some form. Vectorization is difficult to enable, but can yield large efficiency gains. Extra programmer effort is required because: (1) not all algorithms can be vectorized (regular algorithm structure and fine-grain parallelism must be used); (2) most CPUs have data alignment restrictions for load/store operations (obey or risk incorrect code); (3) special directives are often needed to enable vectorization; and (4) vector instructions are architecture-specific. Vectorization is the best way to optimize for power and performance due to reduced clock cycles. When data is organized properly, a vector load instruction (i.e. movaps) can replace 'normal' load instructions (i.e. movsd). Vector operations can potentially have a smaller footprint in the instruction cache when fewer instructions need to be executed. Hybrid index sets insulate users from architecture specific details. We have applied hybrid index sets to achieve optimal vectorization. We can extend this concept to handle other programming models.

  3. Tool setting device

    DOEpatents

    Brown, Raymond J.

    1977-01-01

    The present invention relates to a tool setting device for use with numerically controlled machine tools, such as lathes and milling machines. A reference position of the machine tool relative to the workpiece along both the X and Y axes is utilized by the control circuit for driving the tool through its program. This reference position is determined for both axes by displacing a single linear variable displacement transducer (LVDT) with the machine tool through a T-shaped pivotal bar. The use of the T-shaped bar allows the cutting tool to be moved sequentially in the X or Y direction for indicating the actual position of the machine tool relative to the predetermined desired position in the numerical control circuit by using a single LVDT.

  6. Radial sets: interactive visual analysis of large overlapping sets.

    PubMed

    Alsallakh, Bilal; Aigner, Wolfgang; Miksch, Silvia; Hauser, Helwig

    2013-12-01

    In many applications, data tables contain multi-valued attributes that often store the memberships of the table entities to multiple sets such as which languages a person masters, which skills an applicant documents, or which features a product comes with. With a growing number of entities, the resulting element-set membership matrix becomes very rich of information about how these sets overlap. Many analysis tasks targeted at set-typed data are concerned with these overlaps as salient features of such data. This paper presents Radial Sets, a novel visual technique to analyze set memberships for a large number of elements. Our technique uses frequency-based representations to enable quickly finding and analyzing different kinds of overlaps between the sets, and relating these overlaps to other attributes of the table entities. Furthermore, it enables various interactions to select elements of interest, find out if they are over-represented in specific sets or overlaps, and if they exhibit a different distribution for a specific attribute compared to the rest of the elements. These interactions allow formulating highly-expressive visual queries on the elements in terms of their set memberships and attribute values. As we demonstrate via two usage scenarios, Radial Sets enable revealing and analyzing a multitude of overlapping patterns between large sets, beyond the limits of state-of-the-art techniques.

    We present a fundamental concept - closed sets of correlations - for studying nonlocal correlations. We argue that sets of correlations corresponding to information-theoretic principles, or more generally to consistent physical theories, must be closed under a natural set of operations. Hence, studying the closure of sets of correlations gives insight into which information-theoretic principles are genuinely different, and which are ultimately equivalent. This concept also has implications for understanding why quantum nonlocality is limited, and for finding constraints on physical theories beyond quantum mechanics.

    The work of von Neumann tells us that the logic of quantum mechanics is not Boolenan. This suggests the formulation of a quantum theory of sets based on quantum logic much as modern set theory is based on Boolean logic. In the first part of this dissertation such a quantum set theory is developed. In the second part, quantum set theory is proposed as a universal language for physics. A quantum topology and the beginnings of a quantum geometry are developed in this language. Finally, a toy model is studied. It gives indications of possible lines for progress in this program.

    With advances in x-ray microtomography, it is now possible to obtain three-dimensional representations of a material’s microstructure with a voxel size of less than one micrometer. The Visible Cement Data Set represents a collection of 3-D data sets obtained using the European Synchrotron Radiation Facility in Grenoble, France in September 2000. Most of the images obtained are for hydrating portland cement pastes, with a few data sets representing hydrating Plaster of Paris and a common building brick. All of these data sets are being made available on the Visible Cement Data Set website at http://visiblecement.nist.gov. The website includes the raw 3-D datafiles, a description of the material imaged for each data set, example two-dimensional images and visualizations for each data set, and a collection of C language computer programs that will be of use in processing and analyzing the 3-D microstructural images. This paper provides the details of the experiments performed at the ESRF, the analysis procedures utilized in obtaining the data set files, and a few representative example images for each of the three materials investigated.

    2001-07-19

    We present a new wavelet compression and multiresolution modeling approach for sets of contours (level sets). In contrast to previous wavelet schemes, our algorithm creates a parametrization of a scalar field induced by its contoum and compactly stores this parametrization rather than function values sampled on a regular grid. Our representation is based on hierarchical polygon meshes with subdivision connectivity whose vertices are transformed into wavelet coefficients. From this sparse set of coefficients, every set of contours can be efficiently reconstructed at multiple levels of resolution. When applying lossy compression, introducing high quantization errors, our method preserves contour topology, in contrast to compression methods applied to the corresponding field function. We provide numerical results for scalar fields defined on planar domains. Our approach generalizes to volumetric domains, time-varying contours, and level sets of vector fields.

    The Baake construction, based on generating a set of vertices of Penrose tilings as a model set, is refined. An algorithm and a corresponding computer program for constructing an uncountable set of locally indistinguishable Penrose tilings are developed proceeding from this refined construction. Based on an analysis of the parameters of tiling vertices, 62 versions of rhomb combinations at the tiling center are determined. The combinatorial structure of Penrose tiling worms is established. A concept of flip transformations of tilings is introduced that makes it possible to construct Penrose tilings that cannot be implemented in the Baake construction.

    Outbreaks and pseudo-outbreaks in health care settings can be complex and should be evaluated systematically using epidemiologic tools. Laboratory testing is an important part of an outbreak evaluation. Health care personnel, equipment, supplies, water, ventilation systems, and the hospital environment have been associated with health care outbreaks. Settings including the neonatal intensive care unit, endoscopy, oncology, and transplant units are areas that have specific issues which impact the approach to outbreak investigation and control. Certain organisms have a predilection for health care settings because of the illnesses of patients, the procedures performed, and the care provided. PMID:27515142

  1. On limit and limit setting.

    PubMed

    Gorney, J E

    1994-01-01

    This article investigates the role of limit and limit setting within the psychoanalytic situation. Limit is understood to be a boundary between self and others, established as an interactional dimension of experience. Disorders of limit are here understood within the context of Winnicott's conception of the "anti-social tendency." Limit setting is proposed as a necessary and authentic response to the patient's acting out via holding and empathic responsiveness, viewed here as a form of boundary delineation. It is proposed that the patient attempts to repair his or her boundary problem through a seeking of secure limits within the analyst. The setting of secure and appropriate limits must arise from a working through of the analyst's own countertransference response to the patient. It is critical that this response be evoked by, and arise from, the immediate therapeutic interaction so that the patient can experience limit setting as simultaneously personal and authentic.

    We propose a family of boundary terms for the action of a causal set with a spacelike boundary. We show that in the continuum limit one recovers the Gibbons-Hawking-York boundary term in the mean. We also calculate the continuum limit of the mean causal set action for an Alexandrov interval in flat spacetime. We find that it is equal to the volume of the codimension-2 intersection of the two light-cone boundaries of the interval.

    2015-11-01

    Recent evidence suggests that people can simultaneously activate attentional control setting for two distinct colors. However, it is unclear whether both attentional control settings must operate globally across the visual field or whether each can be constrained to a particular spatial location. Using two different paradigms, we investigated participants' ability to apply independent color attentional control settings to distinct regions of space. In both experiments, participants were told to identify red letters in one hemifield and green letters in the opposite hemifield. Additionally, some trials used a "relevant distractor"-a letter that matched the opposite side's target color. In Experiment 1, eight letters appeared (four per hemifield) simultaneously for a brief amount of time and then were masked. Relevant distractors increased the error rate and resulted in a greater number of distractor intrusions than irrelevant distractors. Similar results were observed in Experiment 2 in which red and green targets were presented in two rapid serial visual presentation streams. Relevant distractors were found to produce an attentional blink similar in magnitude to an actual target. The results of both experiments suggest that letters matching either attentional control setting were selected by attention and were processed as if they were targets, providing strong evidence that both attentional control settings were applied globally, rather than being constrained to a particular location.

    2012-09-01

    Specific radiation damage can be used for the phasing of macromolecular crystal structures. In practice, however, the optimization of the X-ray dose used to `burn' the crystal to induce specific damage can be difficult. Here, a method is presented in which a single large data set that has not been optimized in any way for radiation-damage-induced phasing (RIP) is segmented into multiple sub-data sets, which can then be used for RIP. The efficacy of this method is demonstrated using two model systems and two test systems. A method to improve the success of this type of phasing experiment by varying the composition of the two sub-data sets with respect to their separation by image number, and hence by absorbed dose, as well as their individual completeness is illustrated.

A series of five sets of three-color images from the rover's panoramic camera was acquired looking toward the southwest. Each set used an infrared, green and violet filter, rather than the human red-green-blue, so that the maximum panoramic camera wavelength range could be covered by the observations, enhancing the scientific value of the measurements.

    A color image was made from the first post-sunset sequence of calibrated color images, with the color balance set to approximate what the sunset color would have looked like to the human eye. The color seen in this first post-sunset image was then used to colorize each image in the sequence. Approximately one-minute gaps between consecutive color images meant the Sun's position changed within each color set, so the images had to be manually shifted to compensate for this motion. In this fashion, the position and brightness of the Sun are taken from each individual image, but the color is taken from a single set of images. The images were then combined into a movie where one color set fades gracefully into the next. Analysis of the five color sets shows that there were only small color variations during the sunset, so most of the real variations are captured in the movie.

    The rapid dimming of the Sun near the horizon is due to the dust in the sky. There is nearly twice as much dust as there was when the Mars Pathfinder spacecraft, which landed on Mars in 1997, imaged the sunset. This causes the Sun to be many times fainter. The sky above the Sun has the same blue tint observed by Pathfinder and also by Viking, which landed on Mars in 1976. This is because dust in the martian atmosphere scatters blue light forward toward the observer much more efficiently than it scatters red light forward. Therefore, a 'halo' of blueish sky color is always observed close to the Sun. We're only seeing

  9. Wide Range SET Pulse Measurement

    Shuler, Robert L.; Chen, Li

    2012-01-01

    A method for measuring a wide range of SET pulses is demonstrated. Use of dynamic logic, faster than ordinary CMOS, allows capture of short pulses. A weighted binning of SET lengths allows measurement of a wide range of pulse lengths with compact circuitry. A pulse-length-conservative pulse combiner tree routes SETs from combinational logic to the measurement circuit, allowing SET measurements in circuits that cannot easily be arranged in long chains. The method is applied to add-multiplex combinational logic, and to an array of NFET routing switches, at .35 micron. Pulses are captured in a chain of Domino Logic AND gates. Propagation through the chain is frozen on the trailing edge by dropping low the second "enable" input to the AND gates. Capacitive loading is increased in the latter stages to create an approximately logarithmic weighted binning, so that a broad range of pulse lengths can be captured with a 10 stage capture chain. Simulations show pulses can be captured which are 1/5th the length of those typically captured with leading edge triggered latch methods, and less than the length of those captured with a trailing edge latch method. After capture, the pulse pattern is transferred to an SEU protected shift register for readout. 64 instances of each of two types of logic are used as targets. One is a full adder with a 4 to 1 mux on its inputs. The other is a 4 x 4 NFET routing matrix. The outputs are passed through buffered XNOR comparators to identify pulses, which are merged in a buffered not-nand (OR) tree designed to avoid pulse absorption as much as possible. The output from each of the two test circuits are input into separate pulse measurement circuits. Test inputs were provided so that the circuit could be bench tested and calibrated. A third SET measurement circuit with no inputs was used to judge the contribution from direct hits on the measurement circuit. Heavy ions were used with an LET range from 12 to 176. At LET of 21 and below, the very

    The recent decades have witnessed a significant expansion in the diversity of career paths within academic surgery. Although the skills for providing exemplary surgical care and for maintaining a strong work ethic are the foundations of an academic surgeon, deliberate career planning and organized acquisition of research skills contribute to the success of an academic career. In this article, we identify a set of core academic skills and propose a framework for acquiring them. We also describe specific career paths within academic surgery and provide an overview of the opportunities for acquiring specific skill sets. The development of an academic career is challenging, and firm knowledge of the personal motivations will sustain and endure the time needed for acquiring the needed skills. PMID:25067917

    2013-01-29

    An optical set-reset (SR) latch is formed from a first electroabsorption modulator (EAM), a second EAM and a waveguide photodetector (PD) which are arranged in an optical and electrical feedback loop which controls the transmission of light through the first EAM to latch the first EAM in a light-transmissive state in response to a Set light input. A second waveguide PD controls the transmission of light through the second EAM and is used to switch the first EAM to a light-absorptive state in response to a Reset light input provided to the second waveguide PD. The optical SR latch, which may be formed on a III-V compound semiconductor substrate (e.g. an InP or a GaAs substrate) as a photonic integrated circuit (PIC), stores a bit of optical information and has an optical output for the logic state of that bit of information.

    Poor communication in the perioperative setting contributes to an unsafe OR culture and affects patient safety and employee engagement, decision making, productivity, morale, and retention. Communication breakdowns can lead to surgical delays, patient inconvenience, and serious errors. Simplification and standardization of communication processes and the use of effective communication skills (eg, clear verbal communication, awareness of the effects of nonverbal communication, use of listening and conflict management skills) are ways to improve OR interactions and minimize or prevent errors.

    An apparatus is provided for the precise setting to zero of electrically conductive cutting tools used in the machining of work pieces. An electrically conductive cylindrical pin, tapered at one end to a small flat, rests in a vee-shaped channel in a base so that its longitudinal axis is parallel to the longitudinal axis of the machine's spindle. Electronic apparatus is connected between the cylindrical pin and the electrically conductive cutting tool to produce a detectable signal when contact between tool and pin is made. The axes of the machine are set to zero by contact between the cutting tool and the sides, end or top of the cylindrical pin. Upon contact, an electrical circuit is completed, and the detectable signal is produced. The tool can then be set to zero for that axis. Should the tool contact the cylindrical pin with too much force, the cylindrical pin would be harmlessly dislodged from the vee-shaped channel, preventing damage either to the cutting tool or the cylindrical pin. 5 figs.

    This paper describes an analytic approach and a computer program for setting priorities among safeguards upgrades. The approach provides safeguards decision makers with a systematic method for allocating their limited upgrade resources. The priorities are set based on the upgrades cost and their contribution to safeguards effectiveness. Safeguards effectiveness is measured by the probability of defeat for a spectrum of potential insider and outsider adversaries. The computer program, MI$ER, can be used alone or as a companion to ET and SAVI, programs designed to evaluate safeguards effectiveness against insider and outsider threats, respectively. Setting the priority requires judgments about the relative importance (threat likelihoods and consequences) of insider and outsider threats. Although these judgments are inherently subjective, MI$ER can analyze the sensitivity of the upgrade priorities to these weights and determine whether or not they are critical to the priority ranking. MI$ER produces tabular and graphical results for comparing benefits and identifying the most cost-effective upgrades for a given expenditure. This framework provides decision makers with an explicit and consistent analysis to support their upgrades decisions and to allocate the safeguards resources in a cost-effective manner.

    This paper reports that Texaco Exploration and Production Inc. has completed the first dual lateral horizontal well in East Texas and claimed a horizontal oil well record in the Gulf of Mexico. The East Texas well, 1 Texaco Fee Brookeland, is the company's first dual lateral well. Site is in Newton County. The Brookeland well was drilled vertically to the top of Cretaceous Austin chalk at 9,138 ft. Texaco set casing, then drilled horizontally 3,242 ft to the southeast and 3,000 ft to the northwest for a total horizontal displacement of 6,242 ft. Texaco set an industry record offshore with its B19-ST well on its Teal prospect in Eugene Island Block 338, its first horizontal oil well in the gulf, by drilling a horizontal section of 1,414 ft. Measured depth (MD) is 7,500 ft and true vertical depth (TVD) 4,662 ft. Site is in 268 ft of water. Drilling horizontally through the Pleistocene prograding sand complex allowed Texaco to penetrate 50% more of the reservoir than would have been possible with a conventional well, Wallace the. In another industry first, Texaco isolated the Teal reservoir gas cap by setting intermediate casing 50 ft below the oil-gas contact with the 90{degrees} angle already established because of concern that the reservoir had an expanded gas cap. The dual lateral Brookeland well cost $500,000-700,000 less than two vertical wells capable of comparable production rates and recovery. Texaco expects the full cost of the well, production facilities, and gathering system to pay out in about 4 months. Texaco estimates the B19-ST well cost about 10% more than a Teal vertical well. A cross discipline team of Texaco geologists, geophysicists, engineers, and field technicians contributed to the success of both projects.

    A postoccupancy evaluation (POE) is a systematic assessment performed to examine the effectiveness of the built environment after occupation. Although POEs have been mainly used to examine the effectiveness of built environments for human usage, they can and should be adapted for use in zoological settings. Zoological exhibits have evolved from when hygiene concerns ruled design to current trends that involve elaborate exhibits that often cost millions of dollars. Thus, it is imperative to conduct evaluations to ensure that these exhibits function to meet the complex needs of all users. It is crucial to perform a comprehensive POE that focuses on all three user groups; animals, visitors, and staff. However, work in this field is limited. Animal research has tended to remain very primate-focused with differing opinions as to what constitutes optimal outcomes. Zoo visitor studies often have limited scope and differing methodologies. Additionally, research on zoo staff opinions and feedback is almost nonexistent. A new exhibit opening at a zoo has huge potential for improving the welfare of the animals it will house, enhancing the zoo visitor experience, and improving the workplace for zoo personnel. Building the best possible exhibits requires not only the analysis of how the built environment affects all three groups, but also dissemination of those findings to guide future design.

    A characterization of initial data sets for the Schwarzschild spacetime is provided. This characterization is obtained by performing a 3+1 decomposition of a certain invariant characterization of the Schwarzschild spacetime given in terms of concomitants of the Weyl tensor. This procedure renders a set of necessary conditions--which can be written in terms of the electric and magnetic parts of the Weyl tensor and their concomitants--for an initial data set to be a Schwarzschild initial data set. Our approach also provides a formula for a static Killing initial data set candidate--a KID candidate. Sufficient conditions for an initial data set to be a Schwarzschild initial data set are obtained by supplementing the necessary conditions with the requirement that the initial data set possesses a stationary Killing initial data set of the form given by our KID candidate. Thus, we obtain an algorithmic procedure of checking whether a given initial data set is Schwarzschildean or not.

  17. Ash Aggregates in Proximal Settings

    NASA Astrophysics Data System (ADS)

    Porritt, L. A.; Russell, K.

    2012-12-01

    Ash aggregates are thought to have formed within and been deposited by the eruption column and plume and dilute density currents and their associated ash clouds. Moist, turbulent ash clouds are considered critical to ash aggregate formation by facilitating both collision and adhesion of particles. Consequently, they are most commonly found in distal deposits. Proximal deposits containing ash aggregates are less commonly observed but do occur. Here we describe two occurrences of vent proximal ash aggregate-rich deposits; the first within a kimberlite pipe where coated ash pellets and accretionary lapilli are found within the intra-vent sequence; and the second in a glaciovolcanic setting where cored pellets (armoured lapilli) occur within <1 km of the vent. The deposits within the A418 pipe, Diavik Diamond Mine, Canada, are the residual deposits within the conduit and vent of the volcano and are characterised by an abundance of ash aggregates. Coated ash pellets are dominant but are followed in abundance by ash pellets, accretionary lapilli and rare cored pellets. The coated ash pellets typically range from 1 - 5 mm in diameter and have core to rim ratios of approximately 10:1. The formation and preservation of these aggregates elucidates the style and nature of the explosive phase of kimberlite eruption at A418 (and other pipes?). First, these pyroclasts dictate the intensity of the kimberlite eruption; it must be energetic enough to cause intense fragmentation of the kimberlite to produce a substantial volume of very fine ash (<62 μm). Secondly, the ash aggregates indicate the involvement of moisture coupled with the presence of dilute expanded eruption clouds. The structure and distribution of these deposits throughout the kimberlite conduit demand that aggregation and deposition operate entirely within the confines of the vent; this indicates that aggregation is a rapid process. Ash aggregates within glaciovolcanic sequences are also rarely documented. The

    The instrument has four collection vials that must be filled with ethylene glycol before operation. Each of the four vials should be labeled 1 through 4 and the empty weights recorded. Fill each vial with 80 mL of ethylene glycol and record the weight again. In order for the instrument to operate properly, the collection vials should always have less than 160 mL of total liquid in them. After completing a sample run, remove the collection vials, use a transfer pipette to remove any liquid that might still be on the air paddler, wipe off any condensation from the exterior of the collection vial and record weight. From the instrument, record the ending volume and the time of operation. The solution mixed in the scintillation vial will be 2 ml of a 95% to 50% ethylene glycol to water mixture. To determine the efficiency of counting at all of these concentrations, a series of vials should be set up that consist of 18 ml of Ultima Gold LLT cocktail mixed with standard, regular deionized water and ethylene glycol. The efficiency curve should be counted in the 'Low Level' count mode with the Luminescence Correction ON and the Color Quench Correction ON. Once the tSIE values are determined, chart the cpm against the tSIE numbers and find the best fit for the data. The resulting equation is to be used to converting tSIE values from the collection vials to efficiency. To determine the background cpm value of the ethylene glycol, count a 2 ml sample of ethylene glycol with 18 ml of Ultima Gold for 100 minutes. To determine the total activity of the sample, take two 2 ml aliquots of sample from the first vial and place in separate scintillation vials. Record the weight of each aliquot.

  19. AggreSet: Rich and Scalable Set Exploration using Visualizations of Element Aggregations.

    PubMed

    Datasets commonly include multi-value (set-typed) attributes that describe set memberships over elements, such as genres per movie or courses taken per student. Set-typed attributes describe rich relations across elements, sets, and the set intersections. Increasing the number of sets results in a combinatorial growth of relations and creates scalability challenges. Exploratory tasks (e.g. selection, comparison) have commonly been designed in separation for set-typed attributes, which reduces interface consistency. To improve on scalability and to support rich, contextual exploration of set-typed data, we present AggreSet. AggreSet creates aggregations for each data dimension: sets, set-degrees, set-pair intersections, and other attributes. It visualizes the element count per aggregate using a matrix plot for set-pair intersections, and histograms for set lists, set-degrees and other attributes. Its non-overlapping visual design is scalable to numerous and large sets. AggreSet supports selection, filtering, and comparison as core exploratory tasks. It allows analysis of set relations inluding subsets, disjoint sets and set intersection strength, and also features perceptual set ordering for detecting patterns in set matrices. Its interaction is designed for rich and rapid data exploration. We demonstrate results on a wide range of datasets from different domains with varying characteristics, and report on expert reviews and a case study using student enrollment and degree data with assistant deans at a major public university.

  5. Evolutionary dynamics in set structured populations

    PubMed Central

    Tarnita, Corina E.; Antal, Tibor; Ohtsuki, Hisashi; Nowak, Martin A.

    2009-01-01

    Evolutionary dynamics are strongly affected by population structure. The outcome of an evolutionary process in a well-mixed population can be very different from that in a structured population. We introduce a powerful method to study dynamical population structure: evolutionary set theory. The individuals of a population are distributed over sets. Individuals interact with others who are in the same set. Any 2 individuals can have several sets in common. Some sets can be empty, whereas others have many members. Interactions occur in terms of an evolutionary game. The payoff of the game is interpreted as fitness. Both the strategy and the set memberships change under evolutionary updating. Therefore, the population structure itself is a consequence of evolutionary dynamics. We construct a general mathematical approach for studying any evolutionary game in set structured populations. As a particular example, we study the evolution of cooperation and derive precise conditions for cooperators to be selected over defectors. PMID:19433793

    The relation between two Morse functions defined on a smooth, compact, and orientable 2-manifold can be studied in terms of their Jacobi set. The Jacobi set contains points in the domain where the gradients of the two functions are aligned. Both the Jacobi set itself as well as the segmentation of the domain it induces, have shown to be useful in various applications. In practice, unfortunately, functions often contain noise and discretization artifacts, causing their Jacobi set to become unmanageably large and complex. Although there exist techniques to simplify Jacobi sets, they are unsuitable for most applications as they lack fine-grained control over the process, and heavily restrict the type of simplifications possible. In this paper, we introduce a new framework that generalizes critical point cancellations in scalar functions to Jacobi set in two dimensions. We present a new interpretation of Jacobi set simplification based on the perspective of domain segmentation. Generalizing the cancellation of critical points from scalar functions to Jacobi sets, we focus on simplifications that can be realized by smooth approximations of the corresponding functions, and show how these cancellations imply simultaneous simplification of contiguous subsets of the Jacobi set. Using these extended cancellations as atomic operations, we introduce an algorithm to successively cancel subsets of the Jacobi set with minimal modifications to some user-defined metric. We show that for simply connected domains, our algorithm reduces a given Jacobi set to its minimal configuration, that is, one with no birth–death points (a birth–death point is a specific type of singularity within the Jacobi set where the level sets of the two functions and the Jacobi set have a common normal direction).

  8. Analysis of the heat setting process

    NASA Astrophysics Data System (ADS)

    Besler, N.; Gloy, Y. S.; Gries, T.

    2016-07-01

    Heat setting is an expensive and energy elaborative textile process. Heat setting is necessary to guarantee size accuracy and dimensional stability for textile materials. Depending on the material different heat setting methods such as saturated steam or hot air are used for the fixation. The research aim is to define the influence of heat setting on mechanical characteristics and to analyse the correlation of heat setting parameters for polyester. With the help of a “one factor at a time” experimental design heat setting parameters are varied. Mechanical characteristics and the material quality of heat set and not heat set material are evaluated to analyse the heat setting influence. In the described experimental design up to a temperature of 195 °C and a dwell time of 30 seconds the material shrinkage of polyester is increasing with increasing temperature and dwell time. Shrinkage in wales direction is higher than in course direction. The tensile strength in course direction stays constant whereas the tensile strength in wales direction can be increased by heat setting.

  9. Estimating the CCSD basis-set limit energy from small basis sets: basis-set extrapolations vs additivity schemes

    SciTech Connect

    Spackman, Peter R.; Karton, Amir

    2015-05-15

    Coupled cluster calculations with all single and double excitations (CCSD) converge exceedingly slowly with the size of the one-particle basis set. We assess the performance of a number of approaches for obtaining CCSD correlation energies close to the complete basis-set limit in conjunction with relatively small DZ and TZ basis sets. These include global and system-dependent extrapolations based on the A + B/L{sup α} two-point extrapolation formula, and the well-known additivity approach that uses an MP2-based basis-set-correction term. We show that the basis set convergence rate can change dramatically between different systems(e.g.it is slower for molecules with polar bonds and/or second-row elements). The system-dependent basis-set extrapolation scheme, in which unique basis-set extrapolation exponents for each system are obtained from lower-cost MP2 calculations, significantly accelerates the basis-set convergence relative to the global extrapolations. Nevertheless, we find that the simple MP2-based basis-set additivity scheme outperforms the extrapolation approaches. For example, the following root-mean-squared deviations are obtained for the 140 basis-set limit CCSD atomization energies in the W4-11 database: 9.1 (global extrapolation), 3.7 (system-dependent extrapolation), and 2.4 (additivity scheme) kJ mol{sup –1}. The CCSD energy in these approximations is obtained from basis sets of up to TZ quality and the latter two approaches require additional MP2 calculations with basis sets of up to QZ quality. We also assess the performance of the basis-set extrapolations and additivity schemes for a set of 20 basis-set limit CCSD atomization energies of larger molecules including amino acids, DNA/RNA bases, aromatic compounds, and platonic hydrocarbon cages. We obtain the following RMSDs for the above methods: 10.2 (global extrapolation), 5.7 (system-dependent extrapolation), and 2.9 (additivity scheme) kJ mol{sup –1}.

    2016-04-01

    Given a rational map of the Riemann sphere and a subset A of its Julia set, we study the A-exceptional set, that is, the set of points whose orbit does not accumulate at A. We prove that if the topological entropy of A is less than the topological entropy of the full system then the A-exceptional set has full topological entropy. Furthermore, if the Hausdorff dimension of A is smaller than the dynamical dimension of the system then the Hausdorff dimension of the A-exceptional set is larger than or equal to the dynamical dimension, with equality in the particular case when the dynamical dimension and the Hausdorff dimension coincide. We also discuss the case of a general conformal {{C}1+α} dynamical system and, in particular, certain multimodal interval maps on their Julia set.

    2010-01-01

    Gene Set Enrichment (GSE) is a computational technique which determines whether a priori defined set of genes show statistically significant differential expression between two phenotypes. Currently, the gene sets used for GSE are derived from annotation or pathway databases, which often contain computationally based and unrepresentative data. Here, we propose a novel approach for the generation of comprehensive and biologically derived gene sets, deriving sets through the application of machine learning techniques to gene expression data. These gene sets can be produced for specific tissues, developmental stages or environments. They provide a powerful and functionally meaningful way in which to mine genomewide association and next generation sequencing data in order to identify disease-associated variants and pathways.

  12. Statistical mechanics of maximal independent sets

    2009-12-01

    The graph theoretic concept of maximal independent set arises in several practical problems in computer science as well as in game theory. A maximal independent set is defined by the set of occupied nodes that satisfy some packing and covering constraints. It is known that finding minimum and maximum-density maximal independent sets are hard optimization problems. In this paper, we use cavity method of statistical physics and Monte Carlo simulations to study the corresponding constraint satisfaction problem on random graphs. We obtain the entropy of maximal independent sets within the replica symmetric and one-step replica symmetry breaking frameworks, shedding light on the metric structure of the landscape of solutions and suggesting a class of possible algorithms. This is of particular relevance for the application to the study of strategic interactions in social and economic networks, where maximal independent sets correspond to pure Nash equilibria of a graphical game of public goods allocation.

    We present and define a privacy-preserving problem called the oblivious set-member decision problem, which allows a server to decide whether a private secret of a user is a member of his private set in an oblivious manner. Namely, if the secret belongs to his private set, he does not know which member it is. We propose a quantum solution to the oblivious set-member decision problem. Compared to classical solutions, the proposed quantum protocol achieves an exponential reduction in communication complexity, since it only needs O (1 ) communication cost.

    2007-03-01

    Although sexual dysfunction is an important public-health problem in Nigeria, little research has been conducted on this topic in Nigeria. This cross-sectional study was conducted to determine the prevalence of sexual dysfunction and their correlates among female patients of reproductive age using a questionnaire. Respondents were recruited from the out-patients clinics of a teaching hospital setting in Ile-Ife/ Ijesa administrative health zone, Osun State, Nigeria. Of 384 female patients interviewed, 242 (63%) were sexually dysfunctional. Types of sexual dysfunction included disorder of desire (n=20; 8.3%), disorder of arousal (n=l 3; 5.4%), disorder of orgasm (n=154; 63.6%), and painful coitus (dyspareunia) (n=55; 22.7%). The peak age of sexual dysfunction was observed among the age-group of 26-30 years. Women with higher educational status were mostly affected. The reasons for unsatisfactory sexual life mainly included psychosexual factors and medical illnesses, among which included uncaring partners, present illness, excessive domestic duties, lack of adequate foreplay, present medication, competition among wives in a polygamous family setting, previous sexual abuse, and guilt-feeling of previous pregnancy termination among infertile women. The culture of male dominance in the local environment which makes women afraid of rejection and threats of divorce if they ever complain about sexually-related matters might perpetrate sexual dysfunction among the affected individuals. Sexual dysfunction is a real social and psychological problem in the local environment demanding urgent attention. It is imperative to carry out further research in society at large so that the health and lifestyles of affected women and their partners could be improved. PMID:17615910

    Alves, L. L.; Guerra, V.; Pintassilgo, C. D.

    2013-09-01

    This contribution presents a complete consistent set of electron-impact cross sections for methane (CH4) , recently made available on the IST-LISBON database with the LXCat website. The set is based on the cross sections originally compiled and adjusted in and first used in. The elementary processes taken into account are elastic momentum-transfer, vibrational excitation of the (1,3) and (2,4) modes, total dissociation into neutrals, and ionization producing CH4+and CH3++ H. For the latter two processes we have adjusted the partial ionization cross section of Chatham et al. as to reproduce their measured total ionization. The new cross-section set is validated by comparing calculated and measured electron swarm parameters for E / N = 0.1-400 Td. A discussion of similarities and differences with sets of CH4 cross sections from other databases is also presented. Work partially supported by FCT (Pest-OE/SADG/LA0010/2011).

  11. A smooth introduction to the wavefront set

    NASA Astrophysics Data System (ADS)

    Brouder, Christian; Viet Dang, Nguyen; Hélein, Frédéric

    2014-11-01

    The wavefront set of a distribution describes not only the points where the distribution is singular, but also the ‘directions’ of the singularities. Because of its ability to control the product of distributions, the wavefront set was a key element of recent progress in renormalized quantum field theory in curved spacetime, quantum gravity, the discussion of time machines or quantum energy inequalitites. However, the wavefront set is a somewhat subtle concept whose standard definition is not easy to grasp. This paper is a step-by-step introduction to the wavefront set, with examples and motivation. Many different definitions and new interpretations of the wavefront set are presented. Some of them involve a Radon transform.

  12. Post's program and incomplete recursively enumerable sets.

    PubMed Central

    Harrington, L; Soare, R I

    1991-01-01

    A set A of nonnegative integers is recursively enumerable (r.e.) if A can be computably listed. It is shown that there is a first-order property, Q(X), definable in E, the lattice of r.e. sets under inclusion, such that (i) if A is any r.e. set satisfying Q(A) then A is nonrecursive and Turing incomplete and (ii) there exists an r.e. set A satisfying Q(A). This resolves a long open question stemming from Post's program of 1944, and it sheds light on the fundamental problem of the relationship between the algebraic structure of an r.e. set A and the (Turing) degree of information that A encodes.

    Chung, Chul-Woo; Suraneni, Prannoy; Popovics, John S.; Struble, Leslie J.

    2012-01-09

    Ultrasonic shear wave reflection was used to investigate setting times of cement pastes by measuring the reflection coefficient at the interface between hydrating cement pastes of varying water-to-cement ratio and an ultrasonic buffer material. Several different buffer materials were employed, and the choice of buffer was seen to strongly affect measurement sensitivity; high impact polystyrene showed the highest sensitivity to setting processes because it had the lowest acoustic impedance value. The results show that ultrasonic shear-wave reflection can be used successfully to monitor early setting processes of cement paste with good sensitivity when such a very low impedance buffer is employed. Criteria are proposed to define set times, and the resulting initial and final set times agreed broadly with those determined using the standard penetration resistance test.

    2015-10-01

    Appropriate handling of suicidal tendencies is for certain one of the most important duties within ambulant treatment. As various examples show, occurrence of a suicidal tendency can be chronical as well as acute. Well-known risk factors including current psychopathology and psychodynamics help to identify and assess a suicidal tendency and to take necessary therapeutic options. Some of these can be applied in general, others have to be tailored specifically with respect to the mental disorder in question. Suicide often occurs in an interpersonal context. This fact underlines on one hand the importance and the therapeutic potential of the relationship between the patient and the therapist, on the other hand it results in many cases in a highly stressful situation for the therapist. Significant attention has to be paid to counter transference and its control. Development of an emergency plan and challenges of a „non-suicidal-contract“ are discussed. We recommend an agreement with the patient to contact the therapist in case of not feeling able to control his/her own actions. This agreement includes our guarantee of permanent reachability.

    Background. Patients diagnosed with chronic pain (CP) and rheumatoid arthritis (RA) represent two samples with overlapping symptoms, such as experiencing significant pain. Objectives. To compare the level of psychological distress among patients diagnosed CP attending a specialist pain clinic with those attending a specialist RA clinic. Measures. A cross-sectional study was conducted at an academic specialist chronic pain and rheumatology clinic. Participants. 330 participants included a CP group (n = 167) and a RA group (n = 163) completed a booklet of questionnaires regarding demographic characteristics, duration, and severity of their pain. Psychological and personality variables were compared between the CP and RA participants using a Multivariate Analysis of Covariance (MANCOVA). Results. Level of psychological distress based on the subscales of the DASS (depression, anxiety, and stress), PASS (escape avoidance, cognitive anxiety, fear of pain, and physiological anxiety), and PCS (rumination, magnification, and helplessness) was significantly higher in the CP group compared to the RA group. Categorization of individuals based on DASS severity resulted in significant differences in rates of depression and anxiety symptoms between groups, with a greater number of CP participants displaying more severe depressive and anxiety symptoms. Discussion and Conclusions. This study found greater levels of psychological distress among CP individuals referred to an academic pain clinic when compared to RA patients referred to an academic rheumatology clinic.

    2003-12-01

    One hundred and sixty-three consecutive patients (129 females and 34 males) over 60 years of age attending the Headache Centre of the University of Perugia in the period January 2000-December 2001 were included in the study. One hundred and fifty-two (93.3%) were affected by a primary headache disorder. According to the 1988 IHS Criteria, their prevailing attacks could be diagnosed as migraine without aura (MwoA) in 57.2% of cases (n = 87) and as migraine with aura (MwA) in 11.8% of cases (n = 18). Attacks both in MwoA and MwA were unilateral and of severe-to-moderate intensity in 45% and 50% of cases. Head pain was referred as pulsating by 56% and 38.9% of MwoA patients MwA patients, respectively. Aggravation with routine daily activities was present in 72.4% and 61.1% in MwoA and MwA patient groups. The most frequent accompanying symptoms were photophobia and phonophobia. Headache attacks were of shorter duration in MwA patients, but in 3.4% of MwoA patients attacks lasted between 2 and 4 h. Of patients affected by MwA, 55% referred, together with the typical attacks, symptoms of aura not followed by headache. A worsening of headache in the last 5 years was reported by 67.8% and 44.4% of MwoA and MwA patients, respectively. Of the patients with MwoA, 86.2% (n = 75), and 83.3% (n = 15) of those with MwA used symptomatic drugs for their attacks. In the majority of cases they took more than one analgesic or non steroidal anti-inflammatory drug. A total of 51.7% of patients with MwoA and 55.5% of patients with MwA were under prophylactic treatment. Preventive drugs included antidepressants, beta-blockers, calcium channel antagonists and antiepileptic drugs. The choice of symptomatic or prophylactic drugs was made, in the majority of cases, on the basis of concomitant diseases. PMID:14984227

    Despite the increasing number of patients with Diabetes Mellitus in sub-Saharan Africa, the magnitude of chronic kidney disease among diabetics has not been well established. A study done by Janmohamed et al. found chronic kidney disease in 83.7 % of diabetics which is relatively higher than the prevalence reported elsewhere. However this study was conducted in schistosoma endemic area along the shores of Lake Victoria. Schistosomiasis has been reported to cause a range of renal diseases. Interpretation of these findings should therefore take into account the possibility of schistosomiasis as a possible confounder. PMID:27391318

    Background: Communication skills play an important role in establishing doctor-patient relationship is widely recognized throughout the world. The information passed on to the patients affects the treatment outcomes. Objectives: The present study was undertaken to evaluate the level of awareness among OPD patients about prescribed drugs. Materials and Methods: A total of two hundred sixty four patients having a valid prescription from a doctor practicing in allopathic system, visiting 4 different chemist shops in a North Indian city were enrolled in the study. All the enrolled patients were given a preformed questionnaire to be answered on the spot. Results: It was found that though a considerable number of patients were aware about the therapeutic effects of the drugs and the manner of administration of the medicines; they lacked information regarding the side effects, warnings and the information their doctor may require at the next consultation. Conclusion: The study highlighted the fact that doctors need to spend more time with the patients to make them active participants in the drug therapy. PMID:23776839

    Objectives Psychiatric disorders are increasingly recognized among children and adolescents in Bangladesh. Psychiatric disorders are more common in children with chronic and acute pediatric disorders. Our study was designed to determine the psychiatric disorders among children and adolescents attending pediatric outpatient departments of tertiary care hospitals. Methods This cross-sectional study was carried out from July 2012 to February 2013 in pediatric outpatient departments of three prime tertiary level hospitals of Dhaka, Bangladesh. A purposive sampling technique was used. A total of 240 male and female children aged 5 to 16 years old were included in the study. We used a semi-structured questionnaire to obtain sociodemographic and other relevant clinical information about the children and their families from their parents or caregivers and a validated parent version of the Bangla Development and Well-Being Assessment (DAWBA) for measuring psychopathology. Results The mean age of the children was 9.0± 2.6 years. The majority (71%) of children were in the 5–10 year age group. The male/female ratio was 1.2:1. Among the respondents, 18% were found to have a psychiatric disorder. Behavioral disorders, emotional disorders, and developmental disorders were found in 9.0%, 15.0% and 0.4% respectively. Hyperkinetic disorder was the single most frequent (5.0%) psychiatric disorder. Conclusions A significant number of children were found to have psychiatric disorders. Our study indicates the importance of identification and subsequent management of psychiatric conditions among the pediatric population. PMID:27403237

    2016-02-01

    A pre-test and post-test quasi-experimental matched pairs design was used to assess the effectiveness of a week-long multi-therapist intensive outpatient intervention process with clergy suffering from depression and burnout. Participants (n = 23) in the "Clergy in Kairos" program of the Pastoral Institute (Muse in J Pastor Care Couns 61(3):183-195, 2007) constituted the experimental variable. Clergy surveyed from United Methodist and Presbyterian denominations (n = 121) provided a control group from which 23 respondents were selected whose pre-test scores in depression and burnout were statistically equivalent to those in the experimental group. The treatment group consisted of clergy from three denominations who self-selected (or in some cases were referred by denominational officials) into the program. At the outset, clergy in both groups reported equivalent levels of conflict, emotional exhaustion, depersonalization, and depression. At the 6-months follow-up, clergy in the experimental group showed significant improvement of depression, emotional exhaustion, and depersonalization scores. By contrast, there was no change in the burnout and depression scores in the control group at 6-months post-test. Findings suggest the usefulness of a week-long multi-therapist intensive outpatient intervention in reducing burnout and depression. PMID:25682015

    Background: Protecting households from risk of impoverishment due to out-of-pocket costs in health care is a major challenge for health systems. Therefore, this study aimed at evaluating some health expenditure of inpatient and outpatient care as well as assessing the predictors of catastrophic costs for inpatient care in one of central provinces of Iran. Methods: In this cross-sectional study, 760 household were selected by multistage sampling method in Markazi province of Iran and interviewed in order to complete a standard questionnaire. Catastrophic costs were evaluated in a scale that varied from 0 (no money for care) to 100 (spending all income and wealth). Patients who were paid over 20% of household financial sources or 40% of month income were regarded as being exposed to catastrophic costs. Negative binomial model with robust estimator logit function was used for prediction of catastrophic costs. Results: Based on data analysis, 42.6% of hospitalized subjects encountered catastrophic costs. Moreover, 11.2% households faced catastrophic cost among all participated households and 39.3% were reported to need inpatient need care. Multivariate regression model showed that age range 40-59 years and being in the lower levels of wealth index were significant predictors of facing catastrophic costs (P < 0.05). Conclusions: Lack of money is the most important cause of un-seeking care. Hospitalizations due to inpatient care needs, household members aged 40-59 years old, especially with chronic diseases and nonrich status of the household were the highest predictors of facing catastrophic costs. Reducing out-of-pocket costs can increase health care utilization. PMID:25489451

Results The prevalence of ≥10 mmHg systolic inter-arm blood pressure difference was 5.0% was more as compared to 3.8% had diastolic inter-arm blood pressure difference. The prevalence of systolic and diastolic inter-arm difference between 6 to 10 mmHg was 31.4% and 27.9% respectively. Mean systolic inter-arm blood pressure difference was significantly higher among those patients had a multisystem disorder (10.57±0.98 mmHg) and followed by patients with cardiovascular disease (10.22±0.67 mmHg) as compared to healthy patients (2.71±0.96 mmHg). Various diseases highly influenced the increase in blood pressure irrespective of systolic or diastolic was confirmed strongly significant (p<0.001) at different inter arm blood pressure difference levels. Conclusion This study supports the view of inter-arm blood pressure difference as an alarming stage of increased disease risk that incorporated to investigate potential problems at an early diagnostic stage. A significant mean difference between left and right arm blood pressure recorded for many diseases. PMID:27103905

    Government interest in health service "did not attend" (DNA) rates was seen to occur by accident, following which efforts to reduce DNAs have tended to concentrate on operational rather than strategic issues. Considers the effect hospital culture has had on DNA rates from an organizational and patient perspective. Identifies some of the key cultural issues that impacted on DNA rates by utilizing observation and telephone survey research methods. Concludes that, in the main, the lack of customer-oriented organizational culture was seen to affect DNA rates adversely within one NHS provider trust. PMID:10179096

    This paper evaluates the communication of information to physicians who provide off-hours coverage to inpatients in two Family Practice residency programs. METHOD: To describe the importance and accessibility of clinical information used by on-call residents in covering hospital patients, we administered a questionnaire. Then following the use of a new computerized sign-out system in one of the programs, residents filled out the same questionnaire again. RESULTS: Residents felt that a "to do" list and information about the patient's "code status" were the most important data desired from sign-out sheets. However, 69% of residents in both programs felt that provision of this information was normally poor. Nearly all of the residents in Buffalo, using an entirely handwritten sign-out sheet, felt it was in need of improvement. Residents in Pittsburgh, using a summary aided by the hospital's computer print-out, felt this need much less acutely. After implementation of a new computerized sign-out sheet in Buffalo, residents indicated a slightly higher level of satisfaction. The work of data entry and re-entry into the computer was unpopular and inefficient. CONCLUSION: The present method of transferring information at the end of a work day is not satisfactory for residents. Provision of data summaries from existing hospital information systems is a good first step in improving data transfer. A further study of more comprehensive automated sign-out systems is important, because of the increasing discontinuity of house officer care. PMID:1482851

  6. Components of attentional set-switching.

    A series of distinct event-related potentials (ERPs) have been recorded from the scalp of human subjects as they switch from one task to another. It is possible that task switching may depend on different mechanisms depending on whether the switch requires a change in attentional set, in other words the redirecting of attention to different aspects of a sensory stimulus, or whether it requires a change in intentional set, in others words a change in the way that responses are selected. To address this issue, the current study recorded ERPs while subjects switched between attentional sets and the results were compared with those of a previous investigation in which subjects switched between intentional sets. Subjects selected stimuli according to two conflicting attentional sets, each emphasizing one visual stimulus dimension (colour, shape). Pairs of stimuli, only one of which was to be attended, were presented for between eight and seventeen trials then either a switch or a stay cue was shown. The switch cue instructed subjects to switch from the current attentional set to the other set, while the stay cue instructed subjects to maintain the current set. Comparing ERPs time-locked to the switch and stay cues revealed neural correlates of the initiation of a task switch. Comparing the ERPs time locked to the first stimuli after either stay or switch cues identified neural correlates of the implementation of a task switch. A similar modulation over parietal electrodes was seen when subjects were switching between either attentional or intentional sets. While an intentional set switch began with a medial frontal modulation, attentional set switching began with a lateral frontal modulation. Implementing a new attentional set was associated with modulation of relatively early visual potentials, while implementing a new intentional set was associated with modulation of later response-related potentials. The results confirm that task switching consists of a number of

  7. Building complex reference objects from dual sets

    2011-01-01

    There has been considerable psycholinguistic investigation into the conditions that allow separately introduced individuals to be joined into a plural set and represented as a complex reference object (e.g., Eschenbach, et al., 1989; Garrod & Sanford, 1982; Koh & Clifton, 2002; Koh et al., 2008; Moxey et al., 2004; Sanford & Lockhart, 1990). The current paper reports three eye-tracking experiments that investigate the less-well understood question of what conditions allow pointers to be assigned to the individuals within a previously undifferentiated set, turning it into a complex reference object. The experiments made use of a methodology used in Patson and Ferreira (2009) to distinguish between complex reference objects and undifferentiated sets. Experiments 1 and 2 demonstrated that assigning different properties to the members of an undifferentiated dual set via a conjoined modifier or a comparative modifier transformed it into a complex reference object. Experiment 3 indicated that assigning a property to only one member of an undifferentiated dual set introduced pointers to both members. These results demonstrate that pointers can be established to referents within a plural set without picking them out via anaphors; they set boundaries on the kinds of implicit contrasts between referents that establish pointers; and they illustrate that extremely subtle properties of the semantic and referential context can affect early parsing decisions.

    Cole, Reysen, and Kelley [2013. Part-set cuing facilitation for spatial information. Journal of Experimental Psychology: Learning, Memory, & Cognition, 39, 1615-1620] reported robust part-set cuing facilitation for spatial information using snap circuits (a colour-coded electronics kit designed for children to create rudimentary circuit boards). In contrast, Drinkwater, Dagnall, and Parker [2006. Effects of part-set cuing on experienced and novice chess players' reconstruction of a typical chess midgame position. Perceptual and Motor Skills, 102(3), 645-653] and Watkins, Schwartz, and Lane [1984. Does part-set cuing test for memory organization? Evidence from reconstructions of chess positions. Canadian Journal of Psychology/Revue Canadienne de Psychologie, 38(3), 498-503] showed no influence of part-set cuing for spatial information when using chess boards. One key difference between the two procedures was that the snap circuit stimuli were explicitly connected to one another, whereas chess pieces were not. Two experiments examined the effects of connection type (connected vs. unconnected) and cue type (cued vs. uncued) on memory for spatial information. Using chess boards (Experiment 1) and snap circuits (Experiment 2), part-set cuing facilitation only occurred when the stimuli were explicitly connected; there was no influence of cuing with unconnected stimuli. These results are potentially consistent with the retrieval strategy disruption hypothesis, as well as the two- and three-mechanism accounts of part-set cuing. PMID:26252760

  9. Caipirini: using gene sets to rank literature

    PubMed Central

    2012-01-01

    Background Keeping up-to-date with bioscience literature is becoming increasingly challenging. Several recent methods help meet this challenge by allowing literature search to be launched based on lists of abstracts that the user judges to be 'interesting'. Some methods go further by allowing the user to provide a second input set of 'uninteresting' abstracts; these two input sets are then used to search and rank literature by relevance. In this work we present the service 'Caipirini' (http://caipirini.org) that also allows two input sets, but takes the novel approach of allowing ranking of literature based on one or more sets of genes. Results To evaluate the usefulness of Caipirini, we used two test cases, one related to the human cell cycle, and a second related to disease defense mechanisms in Arabidopsis thaliana. In both cases, the new method achieved high precision in finding literature related to the biological mechanisms underlying the input data sets. Conclusions To our knowledge Caipirini is the first service enabling literature search directly based on biological relevance to gene sets; thus, Caipirini gives the research community a new way to unlock hidden knowledge from gene sets derived via high-throughput experiments.

    At the Department of Energy's Idaho Nuclear Technology and Engineering Center, as an interim waste management measure, both mixed high-level liquid waste and sodium bearing waste have been solidified by a calculation process and are stored in the Calcine Solids Storage Facilities. This calcined product will eventually be treated to allow final disposal in a national geologic repository. The Calcine Solids Storage Facilities comprise seven ''bit sets.'' Bin Set 1, the first to be constructed, was completed in 1959, and has been in service since 1963. It is the only bin set that does not meet current safe-shutdown earthquake seismic criteria. In addition, it is the only bin set that lacks built-in features to aid in calcine retrieval. One option to alleviate the seismic compliance issue is to transport the calcine from Bin Set 1 to another bin set which has the required capacity and which is seismically qualified. This report studies the feasibility of retrieving the calcine from Bi n Set 1 and transporting it into Bin Set 6 which is located approximately 650 feet away. Because Bin Set 1 was not designed for calcine retrieval, and because of the high radiation levels and potential contamination spread from the calcined material, this is a challenging engineering task. This report presents preconceptual design studies for remotely-operated, low-density, pneumatic vacuum retrieval and transport systems and equipment that are based on past work performed by the Raytheon Engineers and Constructors architectural engineering firm. The designs presented are considered feasible; however, future development work will be needed in several areas during the subsequent conceptual design phase.

    Humanitarian agencies are increasingly engaged in research in conflict and post-conflict settings. This is justified by the need to improve the quality of assistance provided in these settings and to collect evidence of the highest standard to inform advocacy and policy change. The instability of conflict-affected areas, and the heightened vulnerability of populations caught in conflict, calls for careful consideration of the research methods employed, the levels of evidence sought, and ethical requirements. Special attention needs to be placed on the feasibility and necessity of doing research in conflict-settings, and the harm-benefit ratio for potential research participants. PMID:19591691

    2015-04-01

    In this paper, we consider transition system models of behaviour of Physarum machines in terms of rough set theory. A Physarum machine, a biological computing device implemented in the plasmodium of Physarum polycephalum (true slime mould), is a natural transition system. In the behaviour of Physarum machines, one can notice some ambiguity in Physarum motions that influences exact anticipation of states of machines in time. To model this ambiguity, we propose to use rough set models created over transition systems. Rough sets are an appropriate tool to deal with rough (ambiguous, imprecise) concepts in the universe of discourse.

    1999-01-01

    The removal of indwelling urinary balloon catheters from patients is usually associated with many problems. The problems such as balloon deflation failure; encrustations on balloons, eyes, and lumen; and catheter associated infections are widely discussed in the literature. The tensile set exhibited by the catheter balloon material could also play a role and further complicate the removal process. This article addresses this issue by comparing the tensile set behavior of the balloon material from three commercially available Foley catheters. The balloon materials were subjected to aging in synthetic urine at 37 degrees C for 28 days to simulate clinical conditions. The deflation time of catheter balloons aged in similar conditions were also measured. It was found that different brands of catheters exhibited statistically significant differences in their properties. The tensile set data of the aged samples could be correlated with the deflation time of the balloons. The clinical significance of the tensile set is also highlighted. PMID:10029146

    1987-01-01

    Header design ideology and material selection are described. Current header designs utilize a glass-ceramic insulator which is bonded to a current carrying pin and a metal shell. Residual stresses in the header occur as a result of cooling from the glass softening temperature and are attributable to differences within the header material set in coefficients of thermal expansion. A stress analysis is undertaken to model the residual thermal stresses in glass-ceramic headers. A feature of this model is that it simulates bonding at glass-ceramic to metal interfaces by precluding interfacial sliding. Residual stresses for four material sets are analyzed. These material sets are chosen to illustrate the various stress states which can arise due to differing combinations of coefficients of thermal expansion within a material set. 9 refs., 10 figs., 2 tabs.

    Most work on preference learning has focused on pairwise preferences or rankings over individual items. In this paper, we present a method for learning preferences over sets of items. Our learning method takes as input a collection of positive examples--that is, one or more sets that have been identified by a user as desirable. Kernel density estimation is used to estimate the value function for individual items, and the desired set diversity is estimated from the average set diversity observed in the collection. Since this is a new learning problem, we introduce a new evaluation methodology and evaluate the learning method on two data collections: synthetic blocks-world data and a new real-world music data collection that we have gathered.

    This engineering note documents the calculations of Kelly Dixon, used to determine the maximum allowable set pressure for the argon dewar low relief valve, tag number PSV620A, Anderson Greenwood Type 526J. The original setting was 16 psig. This value was chosen in order to protect against cryostat overpressurization by the source dewar (see D0 Engineering Note 115), however, the following calculations will show that the set pressure can be raised to approximately 18.5 psig, which would result in a faster filling of the cryostat, along with a higher level of liquid argon. Three other engineering notes were revised to reflect the change in set pressure according to this note. They are notes 115, 219, and 263.

    An important data analysis task in statistical genomics involves the integration of genome-wide gene-level measurements with preexisting data on the same genes. A wide variety of statistical methodologies and computational tools have been developed for this general task. We emphasize one particular distinction among methodologies, namely whether they process gene sets one at a time (uniset) or simultaneously via some multiset technique. Owing to the complexity of collections of gene sets, the multiset approach offers some advantages, as it naturally accommodates set-size variations and among-set overlaps. However, this approach presents both computational and inferential challenges. After reviewing some statistical issues that arise in uniset analysis, we examine two model-based multiset methods for gene list data. PMID:25914887

    2013-12-01

    We prove the necessary and sufficient conditions for the informational completeness of an arbitrary set of Gaussian observables on continuous variable systems with a finite number of degrees of freedom. In particular, we show that an informationally complete set either contains a single informationally complete observable, or includes infinitely many observables. We show that for a single informationally complete observable, the minimal outcome space is the phase space, and the corresponding probability distribution can always be obtained from the quantum optical Q-function by linear postprocessing and Gaussian convolution, in a suitable symplectic coordinatization of the phase space. In the case of projection valued Gaussian observables, e.g., generalized field quadratures, we show that an informationally complete set of observables is necessarily infinite. Finally, we generalize the treatment to the case where the measurement coupling is given by a general linear bosonic channel, and characterize informational completeness for an arbitrary set of the associated observables.

The second phase of a three phase plan to establish an integrated software engineering environment for ROSES is examined. It discusses briefly phase one which establishes the basic capability for a modern software development environment to include a tool set, training and standards. Phase two is a tool set integration. The tool set is primarily off-the-shelf tools acquired through vendors or government agencies (public domain). These tools were placed into categories of software development. These categories are: requirements, design, and construction support; verification and validation support; and software management support. The integration of the tool set is being performed through concept prototyping and development of tools specifically designed to support the life cycle and provide transition from one phase to the next.

    In early 1980s, researchers discovered self-setting calcium orthophosphate cements, which are bioactive and biodegradable grafting bioceramics in the form of a powder and a liquid. After mixing, both phases form pastes, which set and harden forming either a non-stoichiometric calcium deficient hydroxyapatite or brushite. Since both of them are remarkably biocompartible, bioresorbable and osteoconductive, self-setting calcium orthophosphate formulations appear to be promising bioceramics for bone grafting. Furthermore, such formulations possess excellent molding capabilities, easy manipulation and nearly perfect adaptation to the complex shapes of bone defects, followed by gradual bioresorption and new bone formation. In addition, reinforced formulations have been introduced, which might be described as calcium orthophosphate concretes. The discovery of self-setting properties opened up a new era in the medical application of calcium orthophosphates and many commercial trademarks have been introduced as a result. Currently such formulations are widely used as synthetic bone grafts, with several advantages, such as pourability and injectability. Moreover, their low-temperature setting reactions and intrinsic porosity allow loading by drugs, biomolecules and even cells for tissue engineering purposes. In this review, an insight into the self-setting calcium orthophosphate formulations, as excellent bioceramics suitable for both dental and bone grafting applications, has been provided.

    When memory sets are random variation sets of the self-similar set and the total number of remaining states in each stage of the division of this set is normalized to unity, the corresponding flux and fractional integral are “robust” and stable under some conditions. This answers an open problem proposed by Alian Le Mehaute et al. in their book entitled Irreversibilitê Temporel et Geometrie Fractale.

Health personnel should be trained according to the plans of integrated health services and health manpower development (HSMD), with a view of placing at the disposal of the system the right kind of manpower, in the right numbers, at the right time, in the right place (WHO 1979, 1985, 1987). Graduates of programmes based on problem-based, community-oriented tracks as opposed to the traditional track should certainly be able to: respond to the health needs and expressed demands of the community, work with the community, stimulate healthy lifestyles and self-care, educate the community as well as their co-workers, solve and stimulate the resolve of both individual and community health problems, orient their own as well as community efforts to health promotion, prevent disease, unnecessary suffering, disability and death, work in and with health teams, if necessary provide leadership to such teams, continue learning lifelong so as to keep competence up to date, and improve this competence as much as possible (Fülöp 1990). A limited literature is available comparing innovative and conventional medical curricula, where the innovative one is based on problem-solving learning with a community-oriented track geared towards community needs (Schmidt 1983). This approach showed that the outcome is better, if directed towards the health needs of the community. PMID:8992253

    We present an approach for generating local numerical basis sets of improving accuracy for first-principles nanoplasmonics simulations within time-dependent density functional theory. The method is demonstrated for copper, silver, and gold nanoparticles that are of experimental interest but computationally demanding due to the semi-core d-electrons that affect their plasmonic response. The basis sets are constructed by augmenting numerical atomic orbital basis sets by truncated Gaussian-type orbitals generated by the completeness-optimization scheme, which is applied to the photoabsorption spectra of homoatomic metal atom dimers. We obtain basis sets of improving accuracy up to the complete basis set limit and demonstrate that the performance of the basis sets transfers to simulations of larger nanoparticles and nanoalloys as well as to calculations with various exchange-correlation functionals. This work promotes the use of the local basis set approach of controllable accuracy in first-principles nanoplasmonics simulations and beyond.

    The Maple Creek watershed covers a 955-square-kilometer area in eastern Nebraska, which is a region dominated by agricultural land use. The Maple Creek watershed is one of seven areas currently included in a nationwide study of the sources, transport, and fate of water and chemicals in agricultural watersheds. This study, known as the topical study of 'Agricultural Chemicals: Sources, Transport, and Fate' is part of the National Water-Quality Assessment Program being conducted by the U.S. Geological Survey. The Program is designed to describe water-quality conditions and trends based on representative surface- and ground-water resources across the Nation. The objective of the Agricultural Chemicals topical study is to investigate the sources, transport, and fate of selected agricultural chemicals in a variety of agriculturally diverse environmental settings. The Maple Creek watershed was selected for the Agricultural Chemicals topical study because its watershed represents the agricultural setting that characterizes eastern Nebraska. This report describes the environmental setting of the Maple Creek watershed in the context of how agricultural practices, including agricultural chemical applications and irrigation methods, interface with natural settings and hydrologic processes. A description of the environmental setting of a subwatershed within the drainage area of Maple Creek is included to improve the understanding of the variability of hydrologic and chemical cycles at two different scales.

    The brain encodes visual information with limited precision. Contradictory evidence exists as to whether the precision with which an item is encoded depends on the number of stimuli in a display (set size). Some studies have found evidence that precision decreases with set size, but others have reported constant precision. These groups of studies differed in two ways. The studies that reported a decrease used displays with heterogeneous stimuli and tasks with a short-term memory component, while the ones that reported constancy used homogeneous stimuli and tasks that did not require short-term memory. To disentangle the effects of heterogeneity and short-memory involvement, we conducted two main experiments. In Experiment 1, stimuli were heterogeneous, and we compared a condition in which target identity was revealed before the stimulus display with one in which it was revealed afterward. In Experiment 2, target identity was fixed, and we compared heterogeneous and homogeneous distractor conditions. In both experiments, we compared an optimal-observer model in which precision is constant with set size with one in which it depends on set size. We found that precision decreases with set size when the distractors are heterogeneous, regardless of whether short-term memory is involved, but not when it is homogeneous. This suggests that heterogeneity, not short-term memory, is the critical factor. In addition, we found that precision exhibits variability across items and trials, which may partly be caused by attentional fluctuations. PMID:22685337

    Trellis coding using multidimensional QAM signal sets is investigated. Finite-size 2D signal sets are presented that have minimum average energy, are 90-deg rotationally symmetric, and have from 16 to 1024 points. The best trellis codes using the finite 16-QAM signal set with two, four, six, and eight dimensions are found by computer search (the multidimensional signal set is constructed from the 2D signal set). The best moderate complexity trellis codes for infinite lattices with two, four, six, and eight dimensions are also found. The minimum free squared Euclidean distance and number of nearest neighbors for these codes were used as the selection criteria. Many of the multidimensional codes are fully rotationally invariant and give asymptotic coding gains up to 6.0 dB. From the infinite lattice codes, the best codes for transmitting J, J + 1/4, J + 1/3, J + 1/2, J + 2/3, and J + 3/4 bit/sym (J an integer) are presented.

    There are well-established methods for reducing the number of support vectors in a trained binary support vector machine, often with minimal impact on accuracy. We show how reduced-set methods can be applied to multiclass SVMs made up of several binary SVMs, with significantly better results than reducing each binary SVM independently. Our approach is based on Burges' approach that constructs each reduced-set vector as the pre-image of a vector in kernel space, but we extend this by recomputing the SVM weights and bias optimally using the original SVM objective function. This leads to greater accuracy for a binary reduced-set SVM, and also allows vectors to be 'shared' between multiple binary SVMs for greater multiclass accuracy with fewer reduced-set vectors. We also propose computing pre-images using differential evolution, which we have found to be more robust than gradient descent alone. We show experimental results on a variety of problems and find that this new approach is consistently better than previous multiclass reduced-set methods, sometimes with a dramatic difference.

    Accurate measurement of B and T cell responses is a valuable tool to study autoimmunity, allergies, immunity to pathogens, and host-pathogen interactions and assist in the design and evaluation of T cell vaccines and immunotherapies. In this context, it is desirable to elucidate a method to select validated reference sets of epitopes to allow detection of T and B cells. However, the ever-growing information contained in the Immune Epitope Database (IEDB) and the differences in quality and subjects studied between epitope assays make this task complicated. In this study, we develop a novel method to automatically select reference epitope sets according to a categorization system employed by the IEDB. From the sets generated, three epitope sets (EBV, mycobacteria and dengue) were experimentally validated by detection of T cell reactivity ex vivo from human donors. Furthermore, a web application that will potentially be implemented in the IEDB was created to allow users the capacity to generate customized epitope sets. PMID:26568965

    The development of novel image processing algorithms requires a diverse and relevant set of training images to ensure the general applicability of such algorithms for their required tasks. Images must be appropriately chosen for the algorithm's intended applications. Image processing algorithms often employ the discrete wavelet transform (DWT) algorithm to provide efficient compression and near-perfect reconstruction of image data. Defense applications often require the transmission of images and video across noisy or low-bandwidth channels. Unfortunately, the DWT algorithm's performance deteriorates in the presence of noise. Evolutionary algorithms are often able to train image filters that outperform DWT filters in noisy environments. Here, we present and evaluate two image sets suitable for the training of such filters for satellite and unmanned aerial vehicle imagery applications. We demonstrate the use of the first image set as a training platform for evolutionary algorithms that optimize discrete wavelet transform (DWT)-based image transform filters for satellite image compression. We evaluate the suitability of each image as a training image during optimization. Each image is ranked according to its suitability as a training image and its difficulty as a test image. The second image set provides a test-bed for holdout validation of trained image filters. These images are used to independently verify that trained filters will provide strong performance on unseen satellite images. Collectively, these image sets are suitable for the development of image processing algorithms for satellite and reconnaissance imagery applications.

    Understanding of the applicability and limitations of electronic-structure methods needs detailed comparison with highly accurate data of representative test sets. A variety of highly valuable test sets have been established in quantum chemistry for small molecules. However, for crystalline solids they are still lacking. We present a representative test set for materials science and engineering (MSE) which includes first and second row elements and their binaries, comprising various crystal structures. This allows for unbiased benchmarking for various chemical interactions. In the MSE test set, we consider cohesive energy, lattice constant, bulk modulus, electronic, band structures and phonons etc. A big effort is made to produce systematically converged results with respect to basis set and k mesh for a hierarchy of electronic-structure methods, ranging from the local-density approximation to advanced orbital-dependent functionals implemented in the all-electron, full-potential FHI-aims code. Furthermore, we use incremental schemes to obtain benchmark values calculated with coupled-cluster approaches.

    PURPOSE Although the inpatient setting has served as the predominant educational site of internal medicine training programs, many changes and factors are currently affecting education in this setting. As a result, many educational organizations are calling for reforms in inpatient training. This report reviews the available literature on specific internal medicine inpatient educational interventions and proposes recommendations for improving internal medicine training in this setting. METHOD We searched Medline for articles published between 1966 and August 2004 which focused on internal medicine training interventions in the inpatient setting; bibliographies of Medline-identified articles, as well as articles suggested by experts in the field provided additional citations. We then reviewed, classified, and abstracted only articles where an assessment of learner outcomes was included. RESULTS Thirteen studies of inpatient internal medicine educational interventions were found that included an outcome assessment. All were single institution studies. The majority of these studies was of poor methodological quality and focused on specific content areas of internal medicine. None assessed the effectiveness or impact of internal medicine core inpatient experiences or curriculum. CONCLUSION This review identifies significant gaps in our understanding of what constitutes effective inpatient education. The paucity of high quality research in the internal medicine inpatient setting highlights the urgent need to formally define and study what constitutes an effective “core” inpatient curriculum.

    SYNOPSIS With the changing healthcare delivery, patients receive care at various settings including acute care hospitals, skilled nursing facilities, outpatient primary care and specialty clinics, as well as at home, exposing them to pathogens in various settings. Various healthcare settings face unique challenges requiring individualized infection control programs. Infection control programs in skilled nursing facilities should address: surveillance for infections and antimicrobial resistance, outbreak investigation and control plan for epidemics, isolation precautions, hand hygiene, staff education, and employee and resident health programs. Infection control programs in ambulatory clinics should address: Triage and standard – transmission based precautions, cleaning, disinfection and sterilization principles, surveillance in surgical clinics, safe injection practices, and bioterrorism and disaster planning for ambulatory clinics.

SIGPI is designed to work with either coherent systems, where the system fails when certain combinations of components fail, or noncoherent systems, where at least one cut set occurs only if at least one component of the system is operating properly. The program can handle conditionally independent components, dependent components, or a combination of component types and has been used to evaluate responses to environmental threats and seismic events. The three data types that can be input are cut set data in disjoint normal form, basic component probabilities for independent basic components, and mean and covariance data for statistically dependent basic components.

    History and methodology of ∆v range set computation is briefly reviewed, followed by a short summary of the ∆v optimal spacecraft servicing problem literature. Service vehicle placement is approached from a ∆v range set viewpoint, providing a framework under which the analysis becomes quite geometric and intuitive. The optimal servicing tour design problem is shown to be a specific instantiation of the metric- Traveling Salesman Problem (TSP), which in general is an NP-hard problem. The ∆v-TSP is argued to be quite similar to the Euclidean-TSP, for which approximate optimal solutions may be found in polynomial time. Applications of range sets are demonstrated using analytical and simulation results.

    The article describes application of Level Set method for two different microfabrication processes. First is shape evolution of during reflow of the glass structure. Investigated problem were approximated by viscous flow of material thus kinetics of the process were known from physical model. Second problem is isotropic wet etching of silicon. Which is much more complicated because dynamics of the shape evolution is strongly coupled with time and geometry shapes history. In etching simulations Level Set method is coupled with Finite Element Method (FEM) that is used for calculation of etching acid concentration that determine geometry evolution of the structure. The problem arising from working with FEM with time varying boundaries was solved with the use of the dynamic mesh technique employing the Level Set formalism of higher dimensional function for geometry description. Isotropic etching was investigated in context of mico-lenses fabrication. Model was compared with experimental data obtained in etching of the silicon moulds used for micro-lenses fabrication.

    Prinz, Wolfgang

    2015-01-01

    This paper outlines a framework for task representation and discusses applications to interference tasks in individual and joint settings. The framework is derived from the Theory of Event Coding (TEC). This theory regards task sets as transient assemblies of event codes in which stimulus and response codes interact and shape each other in particular ways. On the one hand, stimulus and response codes compete with each other within their respective subsets (horizontal interactions). On the other hand, stimulus and response code cooperate with each other (vertical interactions). Code interactions instantiating competition and cooperation apply to two time scales: on-line performance (i.e., doing the task) and off-line implementation (i.e., setting the task). Interference arises when stimulus and response codes overlap in features that are irrelevant for stimulus identification, but relevant for response selection. To resolve this dilemma, the feature profiles of event codes may become restructured in various ways. The framework is applied to three kinds of interference paradigms. Special emphasis is given to joint settings where tasks are shared between two participants. Major conclusions derived from these applications include: (1) Response competition is the chief driver of interference. Likewise, different modes of response competition give rise to different patterns of interference; (2) The type of features in which stimulus and response codes overlap is also a crucial factor. Different types of such features give likewise rise to different patterns of interference; and (3) Task sets for joint settings conflate intraindividual conflicts between responses (what), with interindividual conflicts between responding agents (whom). Features of response codes may, therefore, not only address responses, but also responding agents (both physically and socially). PMID:26029085

    As part of a project undertaken by a local education and training board, a wide range of stakeholders across South London were asked what makes a high-quality practice placement for student nurses, and how that quality could be effectively measured. This article outlines the drafting and testing of a set of quality standards in a mix of provider settings. Although further refinement is required, the standards enabled placement sites to question themselves about their own education and training processes, strengthened their partnership with the training and education board and facilitated the assurance that student nurses receive safe, effective and compassionate preparation when they are on placement.

    Eating disorders are a complex set of illnesses most commonly affecting white adolescent girls and young women. The most common eating disorders seen in the primary care setting are anorexia nervosa, bulimia nervosa, and binge eating disorder. Treatment in the primary care environment ideally involves a physician, therapist, and nutritionist, although complex cases may require psychiatric and other specialist care. Early diagnosis and treatment are associated with improved outcomes, whereas the consequences of untreated eating disorders, particularly anorexia nervosa, can be devastating, including death.

    Before the development of non invasive ventilation (NIV), endotracheal intubation was the only ventilatory therapy available in case of severe respiratory distress and acute respiratory failure. NIV used to be employed in intensive care settings only. Nowadays, the use of NIV has been democratized to include the emergency room, and the pre-hospital care setting for treatment of acute respiratory failure. Cardiogenic pulmonary edema and acute exacerbation of COPD are indications of choice, since NIV improves mortality. The efficiency of the therapy depends on early treatment; however, endotracheal intubation should not be delayed when it becomes necessary. PMID:26449102

    The transport of sediment through a hydrologic system or basin is an extremely complex phenomenon. Many factors affect this movement. Criteria are established for an 'ultimate' or complete sediment data set, and guidelines are given for the collection of alluvial data. The paper describes what parameters need to be measured and stored to obtain a complete sediment and hydraulic data set that could be used to compute sediment transport using any prominently known sediment-transport equation. The criteria address only the collection of data for noncohesive sediment.

    Representative and adequate reserve networks are key to conserving biodiversity. This begs the question, how much of which features need to be placed in protected areas? Setting specifically-derived conservation targets for most ecosystems is common practice; however, this has never been done for sandy beaches. The aims of this paper, therefore, are to propose a methodology for setting conservation targets for sandy beach ecosystems; and to pilot the proposed method using data describing biodiversity patterns and processes from microtidal beaches in South Africa. First, a classification scheme of valued features of beaches is constructed, including: biodiversity features; unique features; and important processes. Second, methodologies for setting targets for each feature under different data-availability scenarios are described. From this framework, targets are set for features characteristic of microtidal beaches in South Africa, as follows. 1) Targets for dune vegetation types were adopted from a previous assessment, and ranged 19-100%. 2) Targets for beach morphodynamic types (habitats) were set using species-area relationships (SARs). These SARs were derived from species richness data from 142 sampling events around the South African coast (extrapolated to total theoretical species richness estimates using previously-established species-accumulation curve relationships), plotted against the area of the beach (calculated from Google Earth imagery). The species-accumulation factor (z) was 0.22, suggesting a baseline habitat target of 27% is required to protect 75% of the species. This baseline target was modified by heuristic principles, based on habitat rarity and threat status, with final values ranging 27-40%. 3) Species targets were fixed at 20%, modified using heuristic principles based on endemism, threat status, and whether or not beaches play an important role in the species' life history, with targets ranging 20-100%. 4) Targets for processes and 5

    Recent interest in synthetic data sets for improving classifier performance raises the question whether pseudo-random defect models provide a good approximation to live data from an OCR perspective. A proposal is presented to evaluate artificial data sets by comparing the confusion matrices genuerated on scanned and synthesized data by a given classifier. The proposed measure applies, in principle, to both isolated character recognition and to printed text. It is argued that the proposed method is more practical than direct comparison of synthetic data with real data.

    The Set8/PR-Set7/KMT5a methyltransferase plays critical roles in governing transcriptional regulation, cell cycle progression and tumorigenesis. Although CRL4Cdt2 was reported to regulate Set8 stability, deleting the PIP motif only led to partial resistance to ultraviolet-induced degradation of Set8, indicating the existence of additional E3 ligase(s) controlling Set8 stability. Furthermore, it remains largely undefined how DNA damage-induced kinase cascades trigger the timely destruction of Set8 to govern tumorigenesis. Here, we report that SCFβ-TRCP earmarks Set8 for ubiquitination and degradation in a casein kinase I-dependent manner, which is activated by DNA-damaging agents. Biologically, both CRL4Cdt2 and SCFβ-TRCP-mediated pathways contribute to ultraviolet-induced Set8 degradation to control cell cycle progression, governing the onset of DNA damage-induced checkpoints. Therefore, like many critical cell cycle regulators including p21 and Cdt1, we uncover a tight regulatory network to accurately control Set8 abundance. Our studies further suggest that aberrancies in this delicate degradation pathway might contribute to aberrant elevation of Set8 in human tumours. PMID:26666832

    Limit setting is an intervention that is frequently used by mental health nurses. However, limit setting is poorly conceptualized, its purpose is unclear, and there are few evidence-based guidelines to assist nurses to set limits in a safe and effective manner. What is known is that the manner in which nurses set limits influences patients' perceptions of the interactions and their emotional and behavioural responses. In this qualitative study, 12 nurses and 12 patients participated in personal, semistructured interviews that aimed to explore limit setting and to propose principles to guide practice. The findings suggested that: (i) limit setting is important to safety in mental health hospitals; (ii) engaging patients in an empathic manner is necessary when setting limits (when nurses engage in an empathic manner, the therapeutic relationship is more likely to be preserved and the risk of aggressive responses is reduced); and (iii) an authoritative (fair, respectful, consistent, and knowledgeable), rather than authoritarian (controlling and indifferent), limit-setting style enhances positive outcomes with regards to adherence, reduced likelihood of aggression, and preservation of the therapeutic relationship. In conclusion, a limit-setting style characterized by empathic responding and an authoritative, rather than authoritarian interpersonal, style is recommended. Elucidating the components of this style is critical for effective training and best practice of mental health nurses, and to reduce aggressive responses from limit setting. PMID:23822138

  18. Peaks theory and the excursion set approach

    NASA Astrophysics Data System (ADS)

    Paranjape, Aseem; Sheth, Ravi K.

    2012-11-01

    We describe a model of dark matter halo abundances and clustering which combines the two most widely used approaches to this problem: that based on peaks and the other based on excursion sets. Our approach can be thought of as addressing the cloud-in-cloud problem for peaks and/or modifying the excursion set approach so that it averages over a special subset, rather than all possible walks. In this respect, it seeks to account for correlations between steps in the walk as well as correlations between walks. We first show how the excursion set and peaks models can be written in the same formalism, and then use this correspondence to write our combined excursion set peaks model. We then give simple expressions for the mass function and bias, showing that even the linear halo bias factor is predicted to be k-dependent as a consequence of the non-locality associated with the peak constraint. At large masses, our model has little or no need to rescale the variable δc from the value associated with spherical collapse, and suggests a simple explanation for why the linear halo bias factor appears to lie above that based on the peak-background split at high masses when such a rescaling is assumed. Although we have concentrated on peaks, our analysis is more generally applicable to other traditionally single-scale analyses of large-scale structure.

  19. Development of CEOP Reference Site Data Sets

    NASA Astrophysics Data System (ADS)

    Loehrer, S. M.; Cully, L. E.; Williams, S. F.

    2003-12-01

    This presentation will discuss the development of a series of specialized observational data sets for the World Climate Research Programme (WCRP) Coordinated Enhanced Observing Period. CEOP is composed of a number of global WCRP research programmes [i.e. Global Energy and Water Cycle Experiment (GEWEX), Climate Variability and Predictability (CLIVAR), and Climate and Cryosphere (CliC)]. Each one of the GEWEX Continental Scale Experiments selected a number of well instrumented reference sites in various climatic regions of the world (36 in total) to support CEOP research activities. These reference sites provide observations of surface meteorology, radiation, fluxes, soils, and atmospheric profiles in a variety of spatial and temporal resolutions in different formats. The University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS) takes these disparate data and conducts a consistent processing and quality assurance methodology leading to the development of a data set in a consistent format and temporal resolution. This presentation will discuss the data processing, quality assurance, and data archival and distribution of the initial CEOP data set (1 July to 30 September 2001) and the current status of (and plans for) the three additional annual cycle data sets that will cover the period from October 2001 to December 2004.

  5. Spin foam models as energetic causal sets

    NASA Astrophysics Data System (ADS)

    Cortês, Marina; Smolin, Lee

    2016-04-01

    Energetic causal sets are causal sets endowed by a flow of energy-momentum between causally related events. These incorporate a novel mechanism for the emergence of space-time from causal relations [M. Cortês and L. Smolin, Phys. Rev. D 90, 084007 (2014); Phys. Rev. D 90, 044035 (2014)]. Here we construct a spin foam model which is also an energetic causal set model. This model is closely related to the model introduced in parallel by Wolfgang Wieland in [Classical Quantum Gravity 32, 015016 (2015)]. What makes a spin foam model also an energetic causal set is Wieland's identification of new degrees of freedom analogous to momenta, conserved at events (or four-simplices), whose norms are not mass, but the volume of tetrahedra. This realizes the torsion constraints, which are missing in previous spin foam models, and are needed to relate the connection dynamics to those of the metric, as in general relativity. This identification makes it possible to apply the new mechanism for the emergence of space-time to a spin foam model. Our formulation also makes use of Markopoulou's causal formulation of spin foams [arXiv:gr-qc/9704013]. These are generated by evolving spin networks with dual Pachner moves. This endows the spin foam history with causal structure given by a partial ordering of the events which are dual to four-simplices.

  8. Irregular sets of two-sided Birkhoff averages and hyperbolic sets

    NASA Astrophysics Data System (ADS)

    Barreira, Luis; Li, Jinjun; Valls, Claudia

    2016-04-01

    For two-sided topological Markov chains, we show that the set of points for which the two-sided Birkhoff averages of a continuous function diverge is residual. We also show that the set of points for which the Birkhoff averages have a given set of accumulation points other than a singleton is residual. A nontrivial consequence of our results is that the set of points for which the local entropies of an invariant measure on a locally maximal hyperbolic set does not exist is residual. This strongly contrasts to the Shannon-McMillan-Breiman theorem in the context of ergodic theory, which says that local entropies exist on a full measure set.

    The problem of finding the maximal membership grade in a fuzzy set of an element from another fuzzy set is an important class of optimisation problems manifested in the real world by situations in which we try to find what is the optimal financial satisfaction we can get from a socially responsible investment. Here, we provide a solution to this problem. We then look at the proposed solution for fuzzy sets with various types of membership grades, ordinal, interval value and intuitionistic.

    2015-01-01

    Objective: Individuals with borderline personality disorder in mental health settings tend to present with relationship difficulties, mood instability/dysphoria, and overt self-harm behavior. In contrast, it appears that individuals with borderline personality disorder in medical settings manifest physical symptoms that are medically difficult to substantiate. Through a review of the literature, we examine 2 symptom manifestations among patients with borderline personality in primary care and general medical settings—namely pain sensitivity and multiple somatic complaints. In addition to reviewing the research of others, we also highlight our own investigations into these 2 areas. Data Sources: We conducted a literature search of the PubMed database and a previous version of the PsycINFO search engine (no restrictions). Search terms included borderline personality, borderline personality disorder, personality disorders; chronic pain, pain, pain syndromes; and somatization disorder, Briquet’s syndrome, somatic preoccupation, somatic. Study Selection: Published articles related to borderline personality, pain and somatic symptoms (ie, somatization disorder, somatic preoccupation) were examined. Results: According to our review, the literature indicates higher-than-expected rates of borderline personality disorder among patients in primary care and general medical settings who present with chronic pain conditions and/or somatic preoccupation. Conclusions: Unlike patients with borderline personality disorder in mental health settings, who tend to present with relationship difficulties, mood instability/dysphoria, and overt self-harm behavior, patients with borderline personality disorder in primary care settings tend to present with unsubstantiated chronic pain of various types as well as somatic preoccupation.

    2014-01-01

    Recently, bipolar fuzzy sets have been studied and applied a bit enthusiastically and a bit increasingly. In this paper we prove that bipolar fuzzy sets and [0,1]2-sets (which have been deeply studied) are actually cryptomorphic mathematical notions. Since researches or modelings on real world problems often involve multi-agent, multi-attribute, multi-object, multi-index, multi-polar information, uncertainty, or/and limit process, we put forward (or highlight) the notion of m-polar fuzzy set (actually, [0,1]m-set which can be seen as a generalization of bipolar fuzzy set, where m is an arbitrary ordinal number) and illustrate how many concepts have been defined based on bipolar fuzzy sets and many results which are related to these concepts can be generalized to the case of m-polar fuzzy sets. We also give examples to show how to apply m-polar fuzzy sets in real world problems. PMID:25025087

    2002-01-01

    This paper examines the approach taken to building a low-cost, modular spacecraft bus that can be used to support a variety of technology experiments in different space environments. It describes the techniques used and design drivers considered to ensure experiment independence from as yet selected host spacecraft. It describes the technology experiment carriers that will support NASA's Living With a Star Space Environment Testbed space missions. NASA has initiated the Living With a Star (LWS) Program to develop a better scientific understanding to address the aspects of the connected Sun-Earth system that affect life and society. A principal goal of the program is to bridge the gap between science, engineering, and user application communities. The Space Environment Testbed (SET) Project is one element of LWS. The Project will enable future science, operational, and commercial objectives in space and atmospheric environments by improving engineering approaches to the accommodation and/or mitigation of the effects of solar variability on technological systems. The SET Project is highly budget constrained and must seek to take advantage of as yet undetermined partnering opportunities for access to space. SET will conduct technology validation experiments hosted on available flight opportunities. The SET Testbeds will be developed in a manner that minimizes the requirements for accommodation, and will be flown as flight opportunities become available. To access the widest range of flight opportunities, two key development requirements are to maintain flexibility with respect to accommodation constraints and to have the capability to respond quickly to flight opportunities. Experiments, already developed to the technology readiness level of needing flight validation in the variable Sun-Earth environment, will be selected on the basis of the need for the subject technology, readiness for flight, need for flight resources and particular orbit. Experiments will be

    Johnson, Jessica

    2012-01-01

    Early in his career, Yongmin Kim adopted an interdisciplinary approach to research that a more ego-driven researcher would have shied away from. He teamed with statisticians, electrical engineers, medical doctors, computer scientists, and industry executives to produce a steady stream of around 450 publications and a slew of innovations to medical imaging equipment that he has often had the pleasure of seeing put to use in hospitals in as short as two years. But Kim did not sit back and bask in his accomplishments. The moment he reached a goal, he set his sights on the next one. Having helped build the University of Washington's Bioengineering Department, where he led students and faculty for 29 years, the IEEE Fellow and former Engineering in Medicine and Biology Society (EMBS) president resigned his tenured faculty position and set out to meet another challenge: serving as president of South Korea's Pohang University of Science and Technology (POSTECH).

  16. Buprenorphine in the workers' compensation setting.

    PubMed

    Colameco, Stephen; Pohl, Mel

    2014-01-01

    Buprenorphine is approved by the Food and Drug Administration for the treatment of chronic pain in low-dose transdermal patch formulations and for the treatment of addiction in high-dose sublingual tablets and films. Clinicians often prescribe these high-dose preparations "off label" for pain management. In the workers' compensation setting, it is particularly important to consider factors such as a) if the injured person has, and is being treated for co-occurring addiction as well as pain; b) if alternative therapies, including opioid withdrawal, were considered prior to initiating buprenorphine treatment; and c) the anticipated duration of treatment. This article reviews buprenorphine's approved indications, formulations, pharmacology, clinical efficacy, and special considerations in the workers' compensation setting. PMID:25162607

    1972-01-28

    The samples and photographs returned from the Apollo 15 site show that Hadley Delta is largely underlain by breccias whose clasts are mainly fragments of coarse-grained feldspathic rocks and nonmare-type basalt. Conspicuous sets of lineaments, visible in surface and orbital photographs of Mount Hadley and Hadley Delta, may represent systematic layering or fracture sets. The mare surface, with regolith about 5 meters thick, is underlain by two major basalt types, at least one of which has extensive lateral continuity and is exposed in the upper wall of Hadley Rille. Gradual erosional recession of the edges and filing of the interior of the rille by talus have contributed to the present cross sectional profile. PMID:17731358

  19. Setting mental health priorities: problems and possibilities.

    PubMed

    Callahan, D

    1994-01-01

    A recent project at the Hastings Center examined the question of priority setting in the provision of mental health services. A central issue was whether those services should be prioritized independently of other health services. The answer to that question was no: they should have full parity. Even so, priority setting can be a complex venture. At the heart of any such effort will be the relationship between empirical evidence on treatment outcomes and efficacy and the political and ethical interests that legitimately bear on interpreting and using that evidence. An argument is made that a priority should be given those whose suffering and inability to function in ordinary life is most pronounced, even if the available treatment for them is comparatively less efficacious than for other conditions.

    2012-01-01

    Adaptation and homeostasis are essential properties of all living systems. However, our knowledge about the reaction kinetic mechanisms leading to robust homeostatic behavior in the presence of environmental perturbations is still poor. Here, we describe, and provide physiological examples of, a set of two-component controller motifs that show robust homeostasis. This basic set of controller motifs, which can be considered as complete, divides into two operational work modes, termed as inflow and outflow control. We show how controller combinations within a cell can integrate uptake and metabolization of a homeostatic controlled species and how pathways can be activated and lead to the formation of alternative products, as observed, for example, in the change of fermentation products by microorganisms when the supply of the carbon source is altered. The antagonistic character of hormonal control systems can be understood by a combination of inflow and outflow controllers. PMID:23199928

    Migraine is a common disorder and is a major cause of disability and loss of working performance in western countries. Therefore, many tools have been developed to assess migraine related disability. Among these, the Migraine Disability Assessment (MIDAS) questionnaire has been shown to be of particular interest, as it is valid, reliable and useful for therapeutic decisions. In this pilot study, we address the validity of the MIDAS questionnaire in an unselected population of migraine patients in the emergency setting. We found that the MIDAS scores in the emergency room were similar to those collected in a specialised headache centre. This result suggests that the MIDAS questionnaire could be reliably used in the emergency setting, hence avoiding unnecessary delays in the treatment of migraine patients. PMID:15549558

    1981-01-01

    The system components and operation of the space shuttle solid rocket booster (SRB) dewatering set are described. The SRB dewatering set consists of a nozzle plug, control console, remote control unit, power distribution unit, umbilical cable, interconnect cables, and various handling and storage items. The nozzle plug (NP) is a remotely controlled, tethered underwater vehicle that is launched from the retrieval vessel (RV) by a crane, descends down the side of the SRB, and is positioned below the SRB nozzle. A TV camera mounted at the top of the NP central core is used by the control console operator to visually guide the NP during descent and docking. The NP is then driven up and locked into the nozzle. Compressed air is passed through the umbilical from the RV, through the NP and into the SRB motor. The water inside the SRB is expelled causing the SRB to rotate to a near horizontal attitude on the surface of the water.

    Law, Arjun Datt; Varma, Subhash Chander

    2014-01-01

    Hypereosinophilia includes a group of commonly encountered clinical situations with symptoms ranging from mild and clinically innocuous to devastating presentations with high morbidity and mortality. The presentations and complications can be easily missed if the clinician is unaware of the diverse entities responsible for hypereosinophilia. The hypereosinophilic syndromes encompass entities that are associated with varying degrees of organ dysfunction either directly due to eosinophilic infiltration or as a result of substances secreted by the eosinophils. These conditions may be neoplastic or reactive in aetiology and a diligent search for secondary causes is essential. Evaluation and management algorithms in the tropical setting and in developing countries may differ from elsewhere. A review of hypereosinophilia and hypereosinophilic syndromes is presented with a diagnostic and therapeutic decision making algorithm modified for use in the tropical setting. PMID:25609866

    PubMed

    Atkinson, Graham

    2009-10-01

    In an attempt to control rapid growth in hospital costs, beginning in the mid-1970s several states implemented rate-setting programs to regulate hospital payments. In seven states, rate-setting was in effect for a substantial period of time (14 years or more). While most of these programs were discontinued by the mid-1990s, two are still active. In five of the seven states, the rates of increase in hospital costs were lower than the corresponding national rates during the periods in which the regulation programs were in place. Four of the states--Maryland, Massachusetts, New York, and New Jersey--had some of the lowest rates of hospital cost increases among all the states. This indicates that hospital rate regulation may be a useful approach in managing a major component of health care spending. PMID:20614649

    2006-05-01

    Core percolation and maximum independent set on random graphs have recently been characterized using the methods of statistical physics. Here we present a statistical physics study of these problems on bond diluted triangular lattices. Core percolation critical behavior is found to be consistent with the standard percolation values, though there are strong finite size effects. A transfer matrix method is developed and applied to find accurate values of the density and degeneracy of the maximum independent set on lattices of limited width but large length. An extrapolation of these results to the infinite lattice limit yields high precision results, which are tabulated. These results are compared to results found using both vertex based and edge based local probability recursion algorithms, which have proven useful in the analysis of hard computational problems, such as the satisfiability problem.

  7. New Test Set for Video Quality Benchmarking

    NASA Astrophysics Data System (ADS)

    Raventos, Joaquin

    A new test set design and benchmarking approach (US Patent pending) allows a "standard observer" to assess the end-to-end image quality characteristics of video imaging systems operating in day time or low-light conditions. It uses randomized targets based on extensive application of Photometry, Geometrical Optics, and Digital Media. The benchmarking takes into account the target's contrast sensitivity, its color characteristics, and several aspects of human vision such as visual acuity and dynamic response. The standard observer is part of the "extended video imaging system" (EVIS). The new test set allows image quality benchmarking by a panel of standard observers at the same time. The new approach shows that an unbiased assessment can be guaranteed. Manufacturers, system integrators, and end users will assess end-to-end performance by simulating a choice of different colors, luminance levels, and dynamic conditions in the laboratory or in permanent video systems installations.

    Objective Translating lessons from clinical trials on the prevention or delay of type 2 diabetes to populations in nonstudy settings remains a challenge. The purpose of this paper is to review, from the perspective of practicing clinicians, available evidence on lifestyle interventions or medication to prevent or delay the onset of type 2 diabetes. Design A MEDLINE search identified 4 major diabetes prevention trials using lifestyle changes and 3 using prophylactic medications. We reviewed the study design, key components, and outcomes for each study, focusing on aspects of the interventions potentially adaptable to clinical settings. Results The lifestyle intervention studies set modest goals for weight loss and physical activity. Individualized counseling helped participants work toward their own goals; behavioral contracting and self-monitoring were key features, and family and social context were emphasized. Study staff made vigorous follow-up efforts for subjects having less success. Actual weight loss by participants was modest; yet, the reduction in diabetes incidence was quite significant. Prophylactic medication also reduced diabetes risk; however, lifestyle changes were more effective and are recommended as first-line strategy. Cost-effectiveness analyses have shown both lifestyle and medication interventions to be beneficial, especially as they might be implemented in practice. Conclusion Strong evidence exists for the prevention or delay of type 2 diabetes through lifestyle changes. Components of these programs may be adaptable for use in clinical settings. This evidence supports broader implementation and increased reimbursement for provider services related to nutrition and physical activity to forestall morbidity from type 2 diabetes. PMID:16423130

    Despite the strong interest of international health agencies, worldwide maternal mortality has not declined substantially over the past 10 years. Postpartum hemorrhage (PPH) is the most common cause of maternal death across the world, responsible for more than 25% of deaths annually. Although effective tools for prevention and treatment of PPH are available, most are not feasible or practical for use in the developing world where many births still occur at home with untrained birth attendants. Application of many available clinical solutions in rural areas would necessitate substantial changes in government infrastructure and in local culture and customs surrounding pregnancy and childbirth. Before treatment can be administered, prompt and accurate diagnosis must be made, which requires training and appropriate blood measurement tools. After diagnosis, appropriate interventions that can be applied in remote settings are needed. Many uterotonics known to be effective in reducing PPH in tertiary care settings may not be useful in community settings because they require refrigeration and/or skilled administration. Moreover, rapid transfer to a higher level of care must be available, a challenge in many settings because of distance and lack of transportation. In light of these barriers, low-technological replacements for treatments commonly applied in the developed-world must be utilized. Community education, improvements to emergency care systems, training for birth attendants, misoprostol, and Uniject have shown promise as potential solutions. In the short term, it is expedient to capitalize on practical opportunities that utilize the existing strengths and resources in each community or region in order to implement appropriate solutions to save the lives of women during childbirth.

    2012-01-01

    OVERVIEW Across the globe, the ways in which patients' test results are managed are as varied as the many different types of healthcare systems that manage these data. The outcomes, however, are often not too dissimilar: too many clinically significant test results fall through the cracks. The consequences of not following up test results in a timely manner are serious and often devastating to patients: diagnoses are delayed, treatments are not initiated or altered in time, and diseases progress. In resource-poor settings, test results too commonly get filed away within the paper chart in ways that isolate them and prevent passage to future providers caring for a patient. To make matters worse, the onus to act upon these test results often rests on patients who need to return to the clinic within a specified timeframe in order to obtain their results but who may not have the means or are too ill to do so. Even in more developed healthcare settings that use electronic records, clinical data residing in the electronic medical record (EMR) are often stubbornly “static”—key pieces of clinical information are frequently not recognized, retrieved, or shared easily. In this way, EMRs are not unlike paper record systems, and therefore, EMRs alone will not solve this problem. To illustrate this problem, consider the case of a patient newly diagnosed with HIV in 3 different healthcare delivery settings. PMID:24278831

  8. Deep Reconstruction Models for Image Set Classification.

    2015-04-01

    Image set classification finds its applications in a number of real-life scenarios such as classification from surveillance videos, multi-view camera networks and personal albums. Compared with single image based classification, it offers more promises and has therefore attracted significant research attention in recent years. Unlike many existing methods which assume images of a set to lie on a certain geometric surface, this paper introduces a deep learning framework which makes no such prior assumptions and can automatically discover the underlying geometric structure. Specifically, a Template Deep Reconstruction Model (TDRM) is defined whose parameters are initialized by performing unsupervised pre-training in a layer-wise fashion using Gaussian Restricted Boltzmann Machines (GRBMs). The initialized TDRM is then separately trained for images of each class and class-specific DRMs are learnt. Based on the minimum reconstruction errors from the learnt class-specific models, three different voting strategies are devised for classification. Extensive experiments are performed to demonstrate the efficacy of the proposed framework for the tasks of face and object recognition from image sets. Experimental results show that the proposed method consistently outperforms the existing state of the art methods. PMID:26353289

  9. Adaptive quantum gate-set tomography

    Quantum information hardware needs to be characterized and calibrated. This is the job of quantum state and process tomography, but standard tomographic methods have an Achilles heel: to characterize an unknown process, they rely on a set of absolutely calibrated measurements. But many technologies (e.g., solid-state qubits) admit only a single native measurement basis, and other bases are measured using unitary control. So tomography becomes circular - tomographic protocols are using gates to calibrate themselves! Gate-set tomography confronts this problem head-on and resolves it by treating gates relationally. We abandon all assumptions about what a given gate operation does, and characterize entire universal gate sets from the ground up using only the observed statistics of an [unknown] 2-outcome measurement after various strings of [unknown] gate operations. The accuracy and reliability of the resulting estimate depends critically on which gate strings are used, and benefits greatly from adaptivity.

    2013-07-01

    Density functional theory (DFT) provides a formally exact framework for performing embedded subsystem electronic structure calculations, including DFT-in-DFT and wavefunction theory-in-DFT descriptions. In the interest of efficiency, it is desirable to truncate the atomic orbital basis set in which the subsystem calculation is performed, thus avoiding high-order scaling with respect to the size of the MO virtual space. In this study, we extend a recently introduced projection-based embedding method [F. R. Manby, M. Stella, J. D. Goodpaster, and T. F. Miller III, J. Chem. Theory Comput. 8, 2564 (2012)], 10.1021/ct300544e to allow for the systematic and accurate truncation of the embedded subsystem basis set. The approach is applied to both covalently and non-covalently bound test cases, including water clusters and polypeptide chains, and it is demonstrated that errors associated with basis set truncation are controllable to well within chemical accuracy. Furthermore, we show that this approach allows for switching between accurate projection-based embedding and DFT embedding with approximate kinetic energy (KE) functionals; in this sense, the approach provides a means of systematically improving upon the use of approximate KE functionals in DFT embedding.

  11. Dynamically weighted clustering with noise set

    PubMed Central

    Shen, Yijing; Sun, Wei; Li, Ker-Chau

    2010-01-01

    Motivation: Various clustering methods have been applied to microarray gene expression data for identifying genes with similar expression profiles. As the biological annotation data accumulated, more and more genes have been organized into functional categories. Functionally related genes may be regulated by common cellular signals, thus likely to be co-expressed. Consequently, utilizing the rapidly increasing functional annotation resources such as Gene Ontology (GO) to improve the performance of clustering methods is of great interest. On the opposite side of clustering, there are genes that have distinct expression profiles and do not co-express with other genes. Identification of these scattered genes could enhance the performance of clustering methods. Results: We developed a new clustering algorithm, Dynamically Weighted Clustering with Noise set (DWCN), which makes use of gene annotation information and allows for a set of scattered genes, the noise set, to be left out of the main clusters. We tested the DWCN method and contrasted its results with those obtained using several common clustering techniques on a simulated dataset as well as on two public datasets: the Stanford yeast cell-cycle gene expression data, and a gene expression dataset for a group of genetically different yeast segregants. Conclusion: Our method produces clusters with more consistent functional annotations and more coherent expression patterns than existing clustering techniques.

  12. Analyzing Document Retrievability in Patent Retrieval Settings

    NASA Astrophysics Data System (ADS)

    Bashir, Shariq; Rauber, Andreas

    Most information retrieval settings, such as web search, are typically precision-oriented, i.e. they focus on retrieving a small number of highly relevant documents. However, in specific domains, such as patent retrieval or law, recall becomes more relevant than precision: in these cases the goal is to find all relevant documents, requiring algorithms to be tuned more towards recall at the cost of precision. This raises important questions with respect to retrievability and search engine bias: depending on how the similarity between a query and documents is measured, certain documents may be more or less retrievable in certain systems, up to some documents not being retrievable at all within common threshold settings. Biases may be oriented towards popularity of documents (increasing weight of references), towards length of documents, favour the use of rare or common words; rely on structural information such as metadata or headings, etc. Existing accessibility measurement techniques are limited as they measure retrievability with respect to all possible queries. In this paper, we improve accessibility measurement by considering sets of relevant and irrelevant queries for each document. This simulates how recall oriented users create their queries when searching for relevant information. We evaluate retrievability scores using a corpus of patents from US Patent and Trademark Office.

    This presentation will discuss the development of a series of specialized observational data sets for the World Climate Research Programme (WCRP) Coordinated Enhanced Observing Period. CEOP is composed of a number of global WCRP research programmes [i.e. Global Energy and Water Cycle Experiment (GEWEX), Climate Variability and Predictability (CLIVAR), and Climate and Cryosphere (CliC)]. Each one of the GEWEX Continental Scale Experiments selected a number of well instrumented reference sites in various climatic regions of the world (36 in total) to support CEOP research activities. These reference sites provide observations of surface meteorology, radiation, fluxes, soils, and atmospheric profiles in a variety of spatial and temporal resolutions in different formats. The University Corporation for Atmospheric Research/Joint Office for Science Support (UCAR/JOSS) takes these disparate data and conducts a consistent processing and quality assurance methodology leading to the development of a data set in a consistent format and temporal resolution. This presentation will discuss the current status of the CEOP EOP-3 (1 October 2002 to 30 September 2003) data processing, quality assurance, and data archival and distribution as well as plans for the remaining CEOP reference site data sets.

  14. Handling Imbalanced Data Sets in Multistage Classification

    NASA Astrophysics Data System (ADS)

    López, M.

    Multistage classification is a logical approach, based on a divide-and-conquer solution, for dealing with problems with a high number of classes. The classification problem is divided into several sequential steps, each one associated to a single classifier that works with subgroups of the original classes. In each level, the current set of classes is split into smaller subgroups of classes until they (the subgroups) are composed of only one class. The resulting chain of classifiers can be represented as a tree, which (1) simplifies the classification process by using fewer categories in each classifier and (2) makes it possible to combine several algorithms or use different attributes in each stage. Most of the classification algorithms can be biased in the sense of selecting the most populated class in overlapping areas of the input space. This can degrade a multistage classifier performance if the training set sample frequencies do not reflect the real prevalence in the population. Several techniques such as applying prior probabilities, assigning weights to the classes, or replicating instances have been developed to overcome this handicap. Most of them are designed for two-class (accept-reject) problems. In this article, we evaluate several of these techniques as applied to multistage classification and analyze how they can be useful for astronomy. We compare the results obtained by classifying a data set based on Hipparcos with and without these methods.

    Substituted phenols, anilines, pyridines and nitrobenzenes can be classified as polar narcotics. These chemicals differ from non-polar narcotic compounds not only in that they exhibit a 5 to 10 times higher toxicity, but also in their Fish Acute Toxic Syndromes, together suggesting a different mode of action. For 97 polar narcotics, which are not ionized under physiological conditions, 11 physico-chemical and quantum-chemical descriptors were calculated. Using Principal Components Analysis 91% of the total variance could be explained by three Principal Components, which were subsequently used as factors in a Statistical Design. Eleven compounds were selected based on a two-level full factorial design, including three compounds near the center (2{sup 3} + 3). QSARs were developed for both, the design set and a set of 63 polar narcotics for which guppy and/or fathead minnow data were available in the literature. Both QSAR, based on PLS, resulted in good models (R{sup 2} = 0.96 and Q{sup 2} = 0.8{sup 2}; R{sup 2}= 0.86 and Q{sup 2} = 0.83 respectively) and gave similar Pseudo Regression Coefficients. In addition the model based on the designed chemicals was able to predict the toxicity of the 63 compounds (R{sup 2} = 0.85). These results show that these 11 chemicals are a well-balanced set for further studies of polar narcosis.

    The very few cognitive training studies targeting an important executive function, set shifting, have reported performance improvements that also generalized to untrained tasks. The present randomized controlled trial extends set shifting training research by comparing previously used cued training with uncued training. A computerized adaptation of the Wisconsin Card Sorting Test was utilized as the training task in a pretest-posttest experimental design involving three groups of university students. One group received uncued training (n = 14), another received cued training (n = 14) and the control group (n = 14) only participated in pre- and posttests. The uncued training group showed posttraining performance increases on their training task, but neither training group showed statistically significant transfer effects. Nevertheless, comparison of effect sizes for transfer effects indicated that our results did not differ significantly from the previous studies. Our results suggest that the cognitive effects of computerized set shifting training are mostly task-specific, and would preclude any robust generalization effects with this training. PMID:24324717

    In 2011, Watson and Barnes proposed a schema for classifying biobanks into 3 groups (mono-, oligo-, and poly-user), primarily based upon biospecimen access policies. We used results from a recent comprehensive survey of cancer biobanks in New South Wales, Australia to assess the applicability of this biobank classification schema in an Australian setting. Cancer biobanks were identified using publically available data, and by consulting with research managers. A comprehensive survey was developed and administered through a face-to-face setting. Data were analyzed using Microsoft Excel™ 2010 and IBM SPSS Statistics™ version 21.0. The cancer biobank cohort (n=23) represented 5 mono-user biobanks, 7 oligo-user biobanks, and 11 poly-user biobanks, and was analyzed as two groups (mono-/oligo- versus poly-user biobanks). Poly-user biobanks employed significantly more full-time equivalent staff, and were significantly more likely to have a website, share staff between biobanks, access governance support, utilize quality control measures, be aware of biobanking best practice documents, and offer staff training. Mono-/oligo-user biobanks were significantly more likely to seek advice from other biobanks. Our results further delineate a biobank classification system that is primarily based on access policy, and demonstrate its relevance in an Australian setting. PMID:26035012

    Development is described of a Comprehensive Ocean-Atmosphere Data Set (COADS)-the result of a cooperative project to collect global weather observations taken near the ocean's surface since 1854, primarily from merchant ships, into a compact and easily used data set. As background, a historical overview is given of how archiving of these marine data has evolved from 1854, when systematic recording of shipboard meteorological and oceanographic observations was first established as an international activity. Input data sets used for COADS are described, as well as the processing steps used to pack input data into compact binary formats and to apply quality controls for identification of suspect weather elements and duplicate marine reports. Seventy-million unique marine reports for 1854-1979 were output from initial processing. Further processing is described, which created statistical summaries for each month of each year of the period, using 2° latitude × 2° longitude boxes. Monthly summary products are available giving 14 statistics (such as the median and the mean) for each of eight observed variables (air and sea-surface temperatures, scalar and vector wind, pressure, humidity, and cloudiness), plus 11 derived variables. Examples of known temporal, spatial, and methodological inhomogeneities in marine data, and plans for periodic updates to COADS, including an update through 1986 scheduled for completion by early 1988, are presented.

    2012-02-01

    Automatic segmentation of the separate human lung lobes is a crucial task in computer aided diagnostics and intervention planning, and required for example for determination of disease spreading or pulmonary parenchyma quantification. In this work, a novel approach for lobe segmentation based on multi-region level sets is presented. In a first step, interlobular fissures are detected using a supervised enhancement filter. The fissures are then used to compute a cost image, which is incorporated in the level set approach. By this, the segmentation is drawn to the fissures at places where structure information is present in the image. In areas with incomplete fissures (e.g. due to insufficient image quality or anatomical conditions) the smoothing term of the level sets applies and a closed continuation of the fissures is provided. The approach is tested on nine pulmonary CT scans. It is shown that incorporating the additional force term improves the segmentation significantly. On average, 83% of the left fissure is traced correctly; the right oblique and horizontal fissures are properly segmented to 76% and 48%, respectively.

  2. Statistical considerations in setting product specifications.

    According to ICH Q6A (1999), a specification is defined as a list of tests, references to analytical procedures, and appropriate acceptance criteria, which are numerical limits, ranges, or other criteria for the tests described. For drug products, specifications usually consist of test methods and acceptance criteria for assay, impurities, pH, dissolution, moisture, and microbial limits, depending on the dosage forms. They are usually proposed by the manufacturers and subject to the regulatory approval for use. When the acceptance criteria in product specifications cannot be pre-defined based on prior knowledge, the conventional approach is to use data from a limited number of clinical batches during the clinical development phases. Often in time, such acceptance criterion is set as an interval bounded by the sample mean plus and minus two to four standard deviations. This interval may be revised with the accumulated data collected from released batches after drug approval. In this article, we describe and discuss the statistical issues of commonly used approaches in setting or revising specifications (usually tighten the limits), including reference interval, (Min, Max) method, tolerance interval, and confidence limit of percentiles. We also compare their performance in terms of the interval width and the intended coverage. Based on our study results and review experiences, we make some recommendations on how to select the appropriate statistical methods in setting product specifications to better ensure the product quality.

    Recently machine learning-based intrusion detection approaches have been subjected to extensive researches because they can detect both misuse and anomaly. In this paper, rough set classification (RSC), a modern learning algorithm, is used to rank the features extracted for detecting intrusions and generate intrusion detection models. Feature ranking is a very critical step when building the model. RSC performs feature ranking before generating rules, and converts the feature ranking to minimal hitting set problem addressed by using genetic algorithm (GA). This is done in classical approaches using Support Vector Machine (SVM) by executing many iterations, each of which removes one useless feature. Compared with those methods, our method can avoid many iterations. In addition, a hybrid genetic algorithm is proposed to increase the convergence speed and decrease the training time of RSC. The models generated by RSC take the form of "IF-THEN" rules, which have the advantage of explication. Tests and comparison of RSC with SVM on DARPA benchmark data showed that for Probe and DoS attacks both RSC and SVM yielded highly accurate results (greater than 99% accuracy on testing set).

    Mandelbrot set is a closure of the set of zeroes of resultant x ( F n , F m ) for iterated maps F n ( x) = f ° n ( x) - x in the moduli space of maps f ( x). The wonderful fact is that for a given n all zeroes are not chaotically scattered around the moduli space, but lie on smooth curves, with just a few cusps, located at zeroes of discriminant x ( F n ). We call this phenomenon the Mandelbrot property. If approached by the cabling method, symmetrically-colored HOMFLY polynomials {H}_n^{{K}}(A|q.) can be considered as linear forms on the n-th "power" of the knot {K} , and one can wonder if zeroes of resultant q 2 ( H n , H m ) can also possess the Mandelbrot property. We present and discuss such resultant-zeroes patterns in the complex- A plane. Though A is hardly an adequate parameter to describe the moduli space of knots, the Mandelbrot-like structure is clearly seen — in full accord with the vision of hep-th/0501235 , that concrete slicing of the Universal Mandelbrot set is not essential for revealing its structure.

  5. The communication process in clinical settings.

    Mathews, J J

    1983-01-01

    The communication of information in clinical settings is fraught with problems despite avowed common aims of practitioners and patients. Some reasons for the problematic nature of clinical communication are incongruent frames of reference about what information ought to be shared, sociolinguistic differences and social distance between practitioners and patients. Communication between doctors and nurses is also problematic, largely due to differences in ideology between the professions about what ought to be communicated to patients about their illness and who is ratified to give such information. Recent social changes, such as the Patient Bill of Rights and informed consent which assure access to information, and new conceptualizations of the nurse's role, warrant continued study of the communication process especially in regard to what constitutes appropriate and acceptable information about a patient's illness and who ought to give such information to patients. The purpose of this paper is to outline characteristics of communication in clinical settings and to provide a literature review of patient and practitioner interaction studies in order to reflect on why information exchange is problematic in clinical settings.

    Let I be a countably infinite set of points in [open face R] which we can write as I={ui: i[set membership][open face Z]}, with uiset I under suitable space-time scalings. Later, we consider some cases when the set I consists of the points of a renewal process and the jump rates assigned to each state in I are perhaps also randomly chosen.This work sprang from a question asked by one of us (Sibson) about ‘driftless nearest-neighbour’ Markov chains on countable subsets I of [open face R]d, work of Sibson [7] and of Christ, Friedberg and Lee [2] having identified examples of such chains in terms of the Dirichlet tessellation associated with I. Amongst methods which can be brought to bear on this d-dimensional problem is the theory of Dirichlet forms. There are potential problems in doing this because we wish I to be random (for example, a realization of a Poisson point process), we do not wish to impose artificial boundedness conditions which would clearly make things work for certain deterministic sets I. In the 1-dimensional case discussed here and in the following paper by Harris, much simpler techniques (where we embed the Markov chain in a Brownian motion using local time) work very effectively; and it is these, rather than the theory of Dirichlet forms, that we use.

  7. Inattentional blindness: A combination of a relational set and a feature inhibition set?

    2016-07-01

    Two experiments were conducted to directly test the feature set hypothesis and the relational set hypothesis in an inattentional blindness task. The feature set hypothesis predicts that unexpected objects that match the to-be-attended stimuli will be reported most. The relational set hypothesis predicts that unexpected objects that match the relationship between the to-be-attended and the to-be-ignored stimuli will be reported the most. Experiment 1 manipulated the luminance of the stimuli. Participants were instructed to monitor the gray letter shapes and to ignore either black or white letter shapes. The unexpected objects that exhibited the luminance relation of the to-be-attended to the to-be-ignored stimuli were reported by participants the most. Experiment 2 manipulated the color of the stimuli. Participants were instructed to monitor the yellower orange or the redder orange letter shapes and to ignore the redder orange or yellower letter shapes. The unexpected objects that exhibited the color relation of the to-be-attended to the to-be-ignored stimuli were reported the most. The results do not support the use of a feature set to accomplish the task and instead support the use of a relational set. In addition, the results point to the concurrent use of multiple attentional sets that are both excitatory and inhibitory. PMID:27001082

  8. Utilizing Maximal Independent Sets as Dominating Sets in Scale-Free Networks

    Derzsy, N.; Molnar, F., Jr.; Szymanski, B. K.; Korniss, G.

    Dominating sets provide key solution to various critical problems in networked systems, such as detecting, monitoring, or controlling the behavior of nodes. Motivated by graph theory literature [Erdos, Israel J. Math. 4, 233 (1966)], we studied maximal independent sets (MIS) as dominating sets in scale-free networks. We investigated the scaling behavior of the size of MIS in artificial scale-free networks with respect to multiple topological properties (size, average degree, power-law exponent, assortativity), evaluated its resilience to network damage resulting from random failure or targeted attack [Molnar et al., Sci. Rep. 5, 8321 (2015)], and compared its efficiency to previously proposed dominating set selection strategies. We showed that, despite its small set size, MIS provides very high resilience against network damage. Using extensive numerical analysis on both synthetic and real-world (social, biological, technological) network samples, we demonstrate that our method effectively satisfies four essential requirements of dominating sets for their practical applicability on large-scale real-world systems: 1.) small set size, 2.) minimal network information required for their construction scheme, 3.) fast and easy computational implementation, and 4.) resiliency to network damage.

  9. A set oriented definition of finite-time Lyapunov exponents and coherent sets

    2013-05-01

    The problem of phase space transport, which is of interest from both the theoretical and practical point of view, has been investigated extensively using geometric and probabilistic methods. Two important tools to study this problem that have emerged in recent years are finite-time Lyapunov exponents (FTLE) and the Perron-Frobenius operator. The FTLE measures the averaged local stretching around reference trajectories. Regions with high stretching are used to identify phase space transport barriers. One probabilistic method is to consider the spectrum of the Perron-Frobenius operator of the flow to identify almost-invariant densities. These almost-invariant densities are used to identify almost invariant sets. In this paper, a set-oriented definition of the FTLE is proposed which is applicable to phase space sets of finite size and reduces to the usual definition of FTLE in the limit of infinitesimal phase space elements. This definition offers a straightforward connection between the evolution of probability densities and finite-time stretching experienced by phase space curves. This definition also addresses some concerns with the standard computation of the FTLE. For the case of autonomous and periodic vector fields we provide a simplified method to calculate the set-oriented FTLE using the Perron-Frobenius operator. Based on the new definition of the FTLE we propose a simple definition of finite-time coherent sets applicable to vector fields of general time-dependence, which are the analogues of almost-invariant sets in autonomous and time-periodic vector fields. The coherent sets we identify will necessarily be separated from one another by ridges of high FTLE, providing a link between the framework of coherent sets and that of codimension one Lagrangian coherent structures. Our identification of coherent sets is applied to three examples.

  11. Fractionation of ethylcellulose oleogels during setting.

    2013-01-01

    The use of ethylcellulose (EC) polymers as a means to structure edible oils for fat replacement is beginning to show great promise and the use of these 'oleogels' has recently been shown to be feasible in food products. These gels are very versatile, as the mechanical properties can be tailored by altering either the fatty acid profile of the oil component, or the viscosity or concentration of the polymer component. Here we report the observation that certain formulation of EC oleogels tend to separate into two distinct phases; a soft interior core surrounded by a firm exterior sheath. It was found that the extent of this effect depends on EC viscosity, and can also be induced through the addition of certain surfactants, such as sorbitan monostearate and sorbitan monooleate, though not by glycerol monooleate. Although the two visually distinct regions were shown to be chemically indistinct, the cooling rate during gel setting was found to play a large role; rapid setting of the gels reduces the fractionation effect, while slow cooling produced a completely homogeneous structure. In addition, by reheating only the soft region of the gel, a firm and soft fractionated gel could again be produced. Finally, it was observed that oleogels prepared with castor oil or mineral oil have the ability to remove or induce the gel separation, respectively. Taken together, these results indicate chemical interactions may incite the separation into two distinct phases, but the process also seems to be driven by the cooling conditions during gel setting. These findings lend insight into the EC-oleogel gelation process and should provide a stepping stone for future research into the manufacturing of these products. PMID:23165763

    The authors consider the problem of counting the number of independent sets or the partition function of a hard-core model in a graph. The problem in general is computationally hard (P hard). They study the quality of the approximation provided by the Bethe free energy. Belief propagation (BP) is a message-passing algorithm can be used to compute fixed points of the Bethe approximation; however, BP is not always guarantee to converge. As the first result, they propose a simple message-passing algorithm that converges to a BP fixed pont for any grapy. They find that their algorithm converges within a multiplicative error 1 + {var_epsilon} of a fixed point in {Omicron}(n{sup 2}E{sup -4} log{sup 3}(nE{sup -1})) iterations for any bounded degree graph of n nodes. In a nutshell, the algorithm can be thought of as a modification of BP with 'time-varying' message-passing. Next, they analyze the resulting error to the number of independent sets provided by such a fixed point of the Bethe approximation. Using the recently developed loop calculus approach by Vhertkov and Chernyak, they establish that for any bounded graph with large enough girth, the error is {Omicron}(n{sup -{gamma}}) for some {gamma} > 0. As an application, they find that for random 3-regular graph, Bethe approximation of log-partition function (log of the number of independent sets) is within o(1) of corret log-partition - this is quite surprising as previous physics-based predictions were expecting an error of o(n). In sum, their results provide a systematic way to find Bethe fixed points for any graph quickly and allow for estimating error in Bethe approximation using novel combinatorial techniques.

  13. Occupational illnesses within two national data sets.

    Leigh, J P; Miller, T R

    1998-01-01

    To describe occupational illness data in two large data sets, two national data sets were aggregated, and the numbers, percentages, and rates of cases of occupational illnesses were determined. Job-related illness data were from Bureau of Labor Statistics documents containing Annual Survey and Census of Fatal Occupational Injury data. A severity index was created to assess the overall burden of a disease. The index multiplies the number of cases times the median days lost. Circulatory disease accounted for 85% of the deaths in the Census and at least 80% in the Annual Survey. More fatal myocardial infarctions occurred on Monday than on any other day. Low-paying occupations had the most myocardial infarctions: operators, laborers, and truck drivers; high-paying occupations had the least: executives, administrators, and managers. Carpal tunnel syndrome and hearing loss accounted for more morbidity, measured by cases and days lost, than any other illness. Persons at great risk for carpal tunnel syndrome included dental hygienists, butchers, sewing machine operators, and dentists. Mental disorders generated more morbidity than is generally acknowledged. Neurotic reactions to stress were highest in the transportation and public utility industries, as well as in finance, insurance, and real estate. Manufacturing contributed far more cases than any other industry. Industries generating significant asbestos-related deaths included construction and boat building. Ninety-three percent of all illness fatalities were among men. Few African Americans died from coal-workers' pneumoconiosis. Illness cases increased much faster than injury cases in recent years. The two data sets provide insights into the incidences and prevalences of occupational illnesses, but underestimate the burden of job-related illnesses. PMID:10026471

    PubMed Central

    2011-01-01

    Asthma prevalence in low-to middle-income countries is at least the same or higher than in rich countries, but with increased severity. Lack of control in these settings is due to various factors such as low accessibility to effective medications, multiple and uncoordinated weak infrastructures of medical services for the management of chronic diseases such as asthma, poor compliance with prescribed therapy, lack of asthma education, and social and cultural factors. There is an urgent requirement for the implementation of better ways to treat asthma in underserved populations, enhancing the access to preventive medications and educational approaches with modern technological methods.

    In this paper, we investigate elliptic functions of the form fΛ = 1/(1 + (℘Λ)2), where ℘Λ is the Weierstrass elliptic function on a real rhombic lattice. We show that a typical function in this family has a superattracting fixed point at the origin and five other equivalence classes of critical points. We investigate conditions on the lattice which guarantee that fΛ has a double toral band, and we show that this family contains the first known examples of elliptic functions for which the Julia set is disconnected but not Cantor.

    Lunsford, James S.

    1991-01-01

    A stabilized off-set voltage is input as the reference voltage to a comparator. In application to a time-interval meter, the comparator output generates a timing interval which is independent of drift in the initial voltage across the timing capacitor. A precision resistor and operational amplifier charge a capacitor to a voltage which is precisely offset from the initial voltage. The capacitance of the reference capacitor is selected so that substantially no voltage drop is obtained in the reference voltage applied to the comparator during the interval to be measured.

    The Tifinagh alphabet-IRCAM is the official alphabet of the Amazigh language widely used in North Africa [1]. It includes thirty-one basic letter and two letters each composed of a base letter followed by the sign of labialization. Normalized only in 2003 (Unicode) [2], ICRAM-Tifinagh is a young character repertoire. Which needs more work on all levels. In this context we propose a data set for handwritten Tifinagh characters composed of 1376 image; 43 Image For Each character. The dataset can be used to train a Tifinagh character recognition system, or to extract the meaning characteristics of each character. PMID:26217753

    2015-12-01

    We describe a practical experimental protocol for robustly characterizing the error rates of non-Clifford gates associated with dihedral groups, including small single-qubit rotations. Our dihedral benchmarking protocol is a generalization of randomized benchmarking that relaxes the usual unitary 2-design condition. Combining this protocol with existing randomized benchmarking schemes enables practical universal gate sets for quantum information processing to be characterized in a way that is robust against state-preparation and measurement errors. In particular, our protocol enables direct benchmarking of the π /8 gate even under the gate-dependent error model that is expected in leading approaches to fault-tolerant quantum computation.

    2015-04-01

    Ranked set sampling (RSS) is a data collection technique that combines measurement with judgment ranking for statistical inference. This paper lays out a formal and natural Bayesian framework for RSS that is analogous to its frequentist justification, and that does not require the assumption of perfect ranking or use of any imperfect ranking models. Prior beliefs about the judgment order statistic distributions and their interdependence are embodied by a nonparametric prior distribution. Posterior inference is carried out by means of Markov chain Monte Carlo techniques, and yields estimators of the judgment order statistic distributions (and of functionals of those distributions).

    The SETS is a remote, non-contacting, high-accuracy tracking system for the measurement of deflection of models in the National Transonic Facility at Langley Research Center. The system consists of four electronically scanned image dissector trackers which locate the position of Light Emitting Diodes embedded in the wing or body of aircraft models. Target location data is recorded on magnetic tape for later 3-D processing. Up to 63 targets per model may be tracked at typical rates of 1280 targets per second and to precision of 0.02mm at the target under the cold (-193 C) environment of the NTF tunnel.

    The method of cancer risk assessment on the basis of the Fuzzy Set Theory is presented. The method is based on a multifactor risk assessment of cancer diseases. The individual risk of cancer disease is evaluated as the probability of disease multiplied by the value of an individual dose. An acupuncture method of cancer risk assessments was developed. The method is based on the analysis of changes of an electromagnetic field (biofield) of a person. The method allows to determine both cancer probability and probable location of the process.

    1998-12-01

    In this paper, we address the problem of choosing appropriate features to describe the content of still pictures or video sequences, including audio. As the computational analysis of these features is often time- consuming, it is useful to identify a minimal set allowing for an automatic classification of some class or genre. Further, it can be shown that deleting the coherence of the features characterizing some class, is not suitable to guarantee an optimal classification result. The central question of the paper is thus, which features should be selected, and how they should be weighted to optimize a classification problem.

    Numerous mathematical models of the interaction of radiation with vegetation canopies have been developed over the last two decades. However, data with which to exercise and validate these models are scarce. During three days in the summer of 1980, experiments are conducted with the objective of gaining insight about the effects of solar illumination and view angles on soybean canopy reflectance. In concert with these experiment, extensive measurements of the soybean canopies are obtained. This document is a compilation of the bidirectional reflectance factors, agronomic, characteristics, canopy geometry, and leaf, stem, and pod optical properties of the soybean canopies. These data sets should be suitable for use with most vegetation canopy reflectance models.

    As pediatric gastrointestinal endoscopy continues to develop and evolve, pediatric gastroenterologists are more frequently called on to develop and direct a pediatric endoscopy unit. Lack of published literature and focused training in fellowship can render decision making about design, capacity, operation, equipment purchasing, and staffing challenging. To help guide management decisions, we distributed a short survey to 18 pediatric gastroenterology centers throughout the United States and Canada. This article provides practical guidance by summarizing available expert opinions on the topic of setting up a pediatric endoscopy unit. PMID:26616893

    We have developed an expert system based on fuzzy logic theory to fuse the data from multiple sensors and make classification decisions for objects in a waste reprocessing stream. Fuzzy set theory has been applied in decision and control applications with some success, particularly by the Japanese. We have found that the fuzzy logic system is rather easy to design and train, a feature that can cut development costs considerably. With proper training, the classification accuracy is quite high. We performed several tests sorting radioactive test samples using a gamma spectrometer to compare fuzzy logic to more conventional sorting schemes.

    Family-centered care is an approach to the planning, delivery, and evaluation of healthcare based on partnership between parents and professionals. Family-centered rounds (FCRs) are a practical application in hospital settings. They are multidisciplinary rounds with active participation of the parents in the decision-making process. FCRs appear to have a positive impact on parents' satisfaction, information provision, and comprehension of care plans. Three concerns have been underlined: time management, confidentiality, and teaching students. FCR implementation is a process that requires in-depth thinking on the philosophy of care, staff information and training, and a specific organizational change. PMID:26774896

    2011-01-01

    We consider the problem of stochastic prediction and control in a time-dependent stochastic environment, such as the ocean, where escape from an almost invariant region occurs due to random fluctuations. We determine high-probability control-actuation sets by computing regions of uncertainty, almost invariant sets, and Lagrangian coherent structures. The combination of geometric and probabilistic methods allows us to design regions of control, which provide an increase in loitering time while minimizing the amount of control actuation. We show how the loitering time in almost invariant sets scales exponentially with respect to the control actuation, causing an exponential increase in loitering times with only small changes in actuation force. The result is that the control actuation makes almost invariant sets more invariant. PMID:21456830

    With the emergence of structural genomics, more effort is being invested into developing methods that incorporate basic crystallographic knowledge to enhance decision making procedures (e.g. Panjikar, 2005). A key area where some crystallographic knowledge is often vital for the smooth progress of structure solution is that of judging the quality or characteristics of an X-ray dataset. For instance, detecting the presence of anisotropic diffraction or twinning while a crystal is on the beam line, may allow the user to change the data collection strategy in order to obtain a better or a more complete data set. In post-collection analyses, the presence of (for instance) non-crystallographic translational symmetry might help the user (or program!) to solve the structure more easily. Of course, the identification of problems is by no means a guarantee that the problems can be overcome, but knowledge of the idiosyncrasies of a given X-ray data set permits the user or software pipeline to tailor the structure solution and refinement procedures to increase the chances of success. In this report, a number of routines are presented that assist the user in detecting specific problems or features within a given dataset. The routines are made available via the open source CCTBX libraries (http://cctbx.sourceforge.net) and will also be included in the next available PHENIX (Adams, et al., 2004) release.

    2015-12-31

    A novel investigation of the nature of intermittency in incompressible, homogeneous, and isotropic turbulence is performed by a numerical study of the Navier-Stokes equations constrained on a fractal Fourier set. The robustness of the energy transfer and of the vortex stretching mechanisms is tested by changing the fractal dimension D from the original three dimensional case to a strongly decimated system with D=2.5, where only about 3% of the Fourier modes interact. This is a unique methodology to probe the statistical properties of the turbulent energy cascade, without breaking any of the original symmetries of the equations. While the direct energy cascade persists, deviations from the Kolmogorov scaling are observed in the kinetic energy spectra. A model in terms of a correction with a linear dependency on the codimension of the fractal set E(k)∼k(-5/3+3-D) explains the results. At small scales, the intermittency of the vorticity field is observed to be quasisingular as a function of the fractal mode reduction, leading to an almost Gaussian statistics already at D∼2.98. These effects must be connected to a genuine modification in the triad-to-triad nonlinear energy transfer mechanism. PMID:26764993

  11. Sequential Auctions in Uncertain Information Settings

    NASA Astrophysics Data System (ADS)

    Fatima, Shaheen; Wooldridge, Michael; Jennings, Nicholas R.

    This paper analyzes sequential auctions for private value objects using second-price sealed-bid rules. Now, the equilibrium bids for such auctions depend on the information uncertainty of the bidders. Specifically, there are three key auction parameters that the bidders could be uncertain about: the valuations of the objects for sale, the number of objects for sale, and the number of participating bidders. We analyse the bidding behaviour for each of these three sources of uncertainty. For each setting, we first find the equilibrium bidding strategies for the individual auctions that comprise a series. Then we analyze the effect of these uncertainties on the computational and economic properties of the equilibrium solution. The former analysis is essential if we want to use software agents to bid on our behalf. The latter is essential because both the auctioneer and the bidders want to know how these uncertainties affect their profits. Thus we compare the outcomes for these settings from the perspective of the bidders (i.e., in terms of their profits), from the perspective of the auctioneer (i.e., in terms of his revenue), and from a global perspective (i.e., in terms of auction efficiency).

    1985-01-01

    It has been recognized for some time that water vapor structure visible in infrared imagery offers a potential for obtaining motion vectors when several images are considered in sequence (Fischer et al., 1981). A study evaluating water vapor winds obtained from the VISSR atmospheric sounder (Stewart et al., 1985) has confirmed the viability of the approach. More recently, 20 data sets have been produced from METEOSAT water vapor imagery for the FGGE period of 10-25 November 1979. Where possible, two data sets were prepared for each day at 0000 and 1200 GMT and compared with rawinsondes over Europe, Africa, and aircraft observations over the oceans. Procedures for obtaining winds were, in general, similar to the earlier study. Motions were detected both by a single pixel tracking and a cross correlation method by using three images individually separated by one hour. A height assignment was determined by matching the measured brightness temperature to the temperature structure represented by the FGGE-IIIB analyses. Results show that the METEOSAT water vapor winds provide uniform horizontal coverage of mid-level flow over the globe with good accuracy.

    2011-01-01

    Hypoglycemia is a common finding in both daily clinical practice and acute care settings. The causes of severe hypoglycemia (SH) are multi-factorial and the major etiologies are iatrogenic, infectious diseases with sepsis and tumor or autoimmune diseases. With the advent of aggressive lowering of HbA1c values to achieve optimal glycemic control, patients are at increased risk of hypoglycemic episodes. Iatrogenic hypoglycemia can cause recurrent morbidity, sometime irreversible neurologic complications and even death, and further preclude maintenance of euglycemia over a lifetime of diabetes. Recent studies have shown that hypoglycemia is associated with adverse outcomes in many acute illnesses. In addition, hypoglycemia is associated with increased mortality among elderly and non-diabetic hospitalized patients. Clinicians should have high clinical suspicion of subtle symptoms of hypoglycemia and provide prompt treatment. Clinicians should know that hypoglycemia is associated with considerable adverse outcomes in many acute critical illnesses. In order to reduce hypoglycemia-associated morbidity and mortality, timely health education programs and close monitoring should be applied to those diabetic patients presenting to the Emergency Department with SH. ED disposition strategies should be further validated and justified to achieve balance between the benefits of euglycemia and the risks of SH. We discuss relevant issues regarding hypoglycemia in emergency and critical care settings. PMID:22028152

    1999-07-01

    A general image analysis and segmentation method using fuzzy set classification and learning is described. The method uses a learned fuzzy representation of pixel region characteristics, based upon the conjunction and disjunction of extracted and derived fuzzy color and texture features. Both positive and negative exemplars of some visually apparent characteristic which forms the basis of the inspection, input by a human operator, are used together with a clustering algorithm to construct positive similarity membership functions and negative similarity membership functions. Using these composite fuzzified images, P and N, are produced using fuzzy union. Classification is accomplished via image defuzzification, whereby linguistic meaning is assigned to each pixel in the fuzzy set using a fuzzy inference operation. The technique permits: (1) strict color and texture discrimination, (2) machine learning of color and texture characteristics of regions, (3) and judicious labeling of each pixel based upon leaned fuzzy representation and fuzzy classification. This approach appears ideal for applications involving visual inspection and allows the development of image-based inspection systems which may be trained and used by relatively unskilled workers. We show three different examples involving the visual inspection of mixed waste drums, lumber and woven fabric.

    1992-01-01

    Paleozoic carbonate mud mounds formed above storm wave base, which in many settings was in moderate to extremely shallow water. This is concluded by a comparative analysis of sedimentary structures, fabrics and small scale sequences occurring in Mississippian and Pennsylvanian mounds and in modern mud mounds and Halimeda bioherms. Most small mounds studied contain a shallowing sequence that represents shallowing into the zone of daily agitation. The bulk of each mound sequence is detrital deposition of layered mudstones to wackestones in the mound core and packstones to grainstones on the flanks and shoal cap. If macroskeletal fauna and flora are present, an autochthonous skeletal packstone may occur in the upper portion of the shallowing sequence beneath the detrital grainstone cap. Burrow excavations and grainy tubular tempestite infillings partially to completely modify the primary depositional fabric of all of these facies. Larger mounds studied are a composite of several to numerous smaller mound depositional sequences. High vertical relief of some larger mounds may be more the result of continued accommodation space provided by subsidence/downfaulting than be deposition in extremely deep water. Although the biotic components of carbonate mounds vary greatly through the Paleozoic, the contained sedimentary structures, fabrics and fundamental depositional sequences remain very similar. This suggests a general similarity in the mechanism and depositional setting of mound formation.

  16. Examining childhood development in contaminated urban settings.

    Normal childhood development and growth is affected by such factors as genetics, nutrition, and multiple familial and social factors. In large urban settings, children are constantly exposed to varying amounts of assorted toxic chemicals both inside and outside the home. Many of these contaminants are suspected to be associated with developmental alterations. The heterogeneity of risk factors in urban populations poses a challenging situation for research. Change must be made in the manner in which developmental toxicological research is undertaken. Plans should be made for immediate data collection after a large-scale exposure to prevent the loss of valuable information. Retrospective studies would benefit from applying rapid assessment techniques to identify high- and low-risk children. In all cases, the development of research design and investigative format needs to reflect the strengths of both social factors and scientific facts. Cross-disciplinary approaches, using physicians and physical and social scientists and incorporating community knowledge, are required for the evaluation of children in urban settings, with each discipline contributing to theory and methodology.

    Background: Providing holistic nursing care when there is a shortage of personnel and equipment exposes nurses to stress and a higher risk of occupational burnout. Humour can promote nurses’ health and influence nursing care. The aim of this study was to describe nurses’ experiences of humour in clinical settings and factors affecting it. Methods: This qualitative study investigated nurses’ experiences of humour. Five hospitals affiliated to Tehran University of Medical Sciences provided the setting for this study. The participants comprised of 17 nurses with master’s and Baccalaureate degrees (BSN) in nursing. These nurses worked at educational hospitals affiliated to Tehran University of Medical Sciences and had minimum work experience of 12 months in various clinical wards. Nurses from all wards were invited to participate in this study. The data were collected through semi structure interviews using guides comprising probing questions. Telephonic interviews were used to further supplement the data. The data were analysed using conventional content analysis. Results: The data were classified into five themes including the dynamics of humour, condition enforcement, Risk making probability, Instrumental use and Change: opportunities and threats. Conclusion: Understanding nurses’ perceptions and experiences of humour helps identify its contributing factors and provides valuable guidelines for enhancing nurses and patients’ mental, emotional and physical health. Spreading a culture of humour through teaching methods can improve workplace cheerfulness and highlights the importance of humour in patient care in nurses and nursing students. PMID:26034735

  18. Compositing multitemporal remote sensing data sets

    To eliminate cloud and atmosphere-affected pixels, the compositing of multi temporal remote sensing data sets is done by selecting the maximum vale of the normalized different vegetation index (NDVI) within a compositing period. The NDVI classifier, however, is strongly affected by surface type and anisotropic properties, sensor viewing geometries, and atmospheric conditions. Consequently, the composited, multi temporal, remote sensing data contain substantial noise from these external conditions. Consequently, the composited, multi temporal, remote sensing data contain substantial noise from these external effects. To improve the accuracy of compositing products, two key approaches can be taken: one is to refine the compositing classifier (NDVI) and the other is to improve existing compositing algorithms. In this project, an alternative classifier was developed and an alternative pixel selection criterion was proposed for compositing. The new classifier and the alternative compositing algorithm were applied to an advanced very high resolution radiometer data set of different biome types in the United States. The results were compared with the maximum value compositing and the best index slope extraction algorithms. The new approaches greatly reduced the high frequency noises related to the external factors and repainted more reliable data. The results suggest that the geometric-optical canopy properties of specific biomes may be needed in compositing. Limitations of the new approaches include the dependency of pixel selection on the length of the composite period and data discontinuity.

  19. Priority setting for health in emerging markets.

    2013-05-01

    The use of health technology assessment research in emerging economies is becoming an increasingly important tool to determine the uses of health spending. As low- and middle-income countries' gross domestic product grows, the funding available for health has increased in tandem. There is growing evidence that comparative effectiveness research and cost-effectiveness can be used to improve health outcomes within a predefined financial space. The use of these evaluation tools, combined with a systematized process of priority setting, can help inform national and global health payers. This review of country institutions for health technology assessment illustrates two points: the efforts underway to use research to inform priorities are widespread and not confined to wealthier countries; and many countries' efforts to create evidence-based policy are incomplete and more country-specific research will be needed. Further evidence shows that there is scope to reduce these gaps and opportunity to support better incorporation of data through better-defined priority-setting processes. PMID:24236627

  20. Setting dietary intake levels: problems and pitfalls.

    PubMed

    Russell, Robert M

    2007-01-01

    Recommended dietary intake levels are the nutrient standards used in designing food assistance programmes, institutional feeding programmes, counselling and teaching. In the USA, the recommended dietary allowances (RDAs) are the basis for setting the poverty threshold and food stamp allotments. In the 1990s, a new paradigm was put forth for estimating nutrient requirements and recommended intake levels. This considered the level of nutrient needed for normal body functioning (versus the amount needed to prevent a deficiency state from occurring). An estimated average requirement (EAR), an RDA and a tolerable upper intake level (UL) were determined for most nutrients. In setting forth these nutrient intake levels (dietary reference intakes, DRIs), a number of data challenges were encountered. For example, it was recognized that for most nutrients there was an absence of dose-response data, and few chronic human or animal studies had been undertaken. In considering how to revise nutrient intake recommendations for populations in the future, the following pitfalls must be overcome: (1) invalid assumption that a threshold level for a requirement will hold for all nutrients; (2) lack of uniform criteria for the selection of the endpoints used (need for evidence-based review, consideration of comparative risk); (3) invalid extrapolations to children for many nutrients; (4) lack of information on variability of responses, and interactions with other nutrients; and (5) lack of understanding in the community of how to use the various DRI numbers.

    Research on the efficacy of yoga for improving mental, emotional, physical, and behavioral health characteristics in school settings is a recent but growing field of inquiry. This systematic review of research on school-based yoga interventions published in peer-reviewed journals offers a bibliometric analysis that identified 47 publications. The studies from these publications have been conducted primarily in the United States (n = 30) and India (n = 15) since 2005, with the majority of studies (n = 41) conducted from 2010 onward. About half of the publications were of studies at elementary schools; most (85%) were conducted within the school curriculum, and most (62%) also implemented a formal school-based yoga program. There was a high degree of variability in yoga intervention characteristics, including overall duration, and the number and duration of sessions. Most of these published research trials are preliminary in nature, with numerous study design limitations, including limited sample sizes (median = 74; range = 20-660) and relatively weak research designs (57% randomized controlled trials, 19% uncontrolled trials), as would be expected in an infant research field. Nevertheless, these publications suggest that yoga in the school setting is a viable and potentially efficacious strategy for improving child and adolescent health and therefore worthy of continued research.

    The Spaceport Command and Control System Project is creating a Checkout and Control System that will eventually launch the next generation of vehicles from Kennedy Space Center. KSC has a large set of Development and Operational equipment already deployed in several facilities, including the Launch Control Center, which requires support. The position of System Administrator will complete tasks across multiple platforms (Linux/Windows), many of them virtual. The Hardware Branch of the Control and Data Systems Division at the Kennedy Space Center uses system administrators for a variety of tasks. The position of system administrator comes with many responsibilities which include maintaining computer systems, repair or set up hardware, install software, create backups and recover drive images are a sample of jobs which one must complete. Other duties may include working with clients in person or over the phone and resolving their computer system needs. Training is a major part of learning how an organization functions and operates. Taking that into consideration, NASA is no exception. Training on how to better protect the NASA computer infrastructure will be a topic to learn, followed by NASA work polices. Attending meetings and discussing progress will be expected. A system administrator will have an account with root access. Root access gives a user full access to a computer system and or network. System admins can remove critical system files and recover files using a tape backup. Problem solving will be an important skill to develop in order to complete the many tasks.

  3. Incompatible Sets of Gradients and Metastability

    2015-12-01

    We give a mathematical analysis of a concept of metastability induced by incompatibility. The physical setting is a single parent phase, just about to undergo transformation to a product phase of lower energy density. Under certain conditions of incompatibility of the energy wells of this energy density, we show that the parent phase is metastable in a strong sense, namely it is a local minimizer of the free energy in an L 1 neighbourhood of its deformation. The reason behind this result is that, due to the incompatibility of the energy wells, a small nucleus of the product phase is necessarily accompanied by a stressed transition layer whose energetic cost exceeds the energy lowering capacity of the nucleus. We define and characterize incompatible sets of matrices, in terms of which the transition layer estimate at the heart of the proof of metastability is expressed. Finally we discuss connections with experiments and place this concept of metastability in the wider context of recent theoretical and experimental research on metastability and hysteresis.

    Previous studies suggest that the implementation of universal precaution (UP) plays a role in reducing HIV stigma. In this study we investigate the efficacy of a stigma reduction intervention on UP compliance and explore whether UP compliance could potentially influence HIV stigma reduction in medical settings. A randomized controlled intervention trial was conducted in two provinces of China with 1760 healthcare service providers recruited from 40 county-level hospitals. Longitudinal analyses included data collection at baseline, 6-, and 12-month follow-up assessments. Using a hierarchical modeling approach, we estimated the intervention effect for each provider’s UP compliance and its potential mediating role on HIV stigma with the bootstrapping method. A significant intervention effect on UP compliance was observed at both the 6- and 12-month follow-up assessments. The intervention effect on provider avoidance intent was partially mediated by the provider’s own UP compliance at the two follow-up points. This study provides evidence that UP compliance should be part of HIV stigma reduction programs, especially in resource-restrained countries. Findings suggest that a protected work environment may be necessary but not sufficient to address HIV stigma in medical settings. PMID:26608559

    The performance of 360T004, Forth Flight, Redesigned Solid Rocket Motors (RSRM) is assessed in respect to joint sealing issues as seen from post-test inspection of the seals and sealing surfaces. The factory joint disassembly inspections for this flight set were omitted. The decision was based on the rational that there is sufficient information in the present data base, and this would give H-7 refurbishment operations faster turn around time for this set of hardware. The factory joint disassembly inspections will resume for 360H005, Fifth Flight, through 360L007, Seventh Flight, due to a new grease application being in effect during the assembly process. The left hand nozzle was forced into the snubbed position upon splash down. This required unique tooling to be manufactured to perform the disassembly of the internal nozzle joints. This was completed on February 5 and 6, 1990 at the H-5 Clearfield, Utah facility. The RSRM consisting of capture feature, field joints with the J-joint insulation configuration is illustrated. The nozzle-to-case joint design, which includes 100, 7/8-inch radial bolts in conjunction with a wiper O-ring and modified insulation design is also illustrated, as is the ignition system seals and a cross section of the igniter. The configuration of all internal nozzle joints is shown.

    In this commentary the urban setting is explored from the perspective of ecological sustainability and social equity. Urban-related issues are highlighted related to social inequality, deficits in urban infrastructures, behavior-related illnesses and risks, global ecological changes, and urban sprawl. Approaches to addressing these issues are described from the perspective of urban governance, urban planning and design, social determinants of health, health promotion, and personal and community empowerment. Examples of successful strategies are provided from Latin America, including using participatory instruments (assessments, evaluation, participatory budgeting, etc.), establishing intersectoral committees, increasing participation of civil society organizations, and developing virtual forums and networks to channel participatory and collaborative processes. A way forward is proposed, using the urban setting to show the imperative of creating intersectoral policies and programs that produce environments that are both healthy and sustainable. It will be important to include new forms of social participation and use social media to facilitate citizen decision-making and active participation of all sectors of society, especially excluded groups.

    1997-01-01

    Etching and deposition of materials are critical steps in semiconductor processing for device manufacturing. Both etching and deposition may have isotropic and anisotropic components, due to directional sputtering and redeposition of materials, for example. Previous attempts at modeling profile evolution have used so-called "string theory" to simulate the moving solid-gas interface between the semiconductor and the plasma. One complication of this method is that extensive de-looping schemes are required at the profile corners. We will present a 2D profile evolution simulation using level set theory to model the surface. (1) By embedding the location of the interface in a field variable, the need for de-looping schemes is eliminated and profile corners are more accurately modeled. This level set profile evolution model will calculate both isotropic and anisotropic etch and deposition rates of a substrate in low pressure (10s mTorr) plasmas, considering the incident ion energy angular distribution functions and neutral fluxes. We will present etching profiles of Si substrates in Ar/Cl2 discharges for various incident ion energies and trench geometries.

    The STIL Tool Set is a set of command-line tools based on STIL, the Starlink Tables Infrastructure Library. It deals with the processing of tabular data; the package has been designed for, but is not restricted to, astronomical tables such as object catalogues. Some of the tools are generic and can work with multiple formats (including FITS, VOTable, CSV, SQL and ASCII), and others are specific to the VOTable format. In some ways, STILTS forms the command-line counterpart of the GUI table analysis tool TOPCAT. The package is robust, fully documented, and designed for efficiency, especially with very large datasets. Facilities offered include: format conversioncrossmatchingplottingcolumn calculation and rearrangementrow selectionsdata and metadata manipulation and displaysortingstatistical calculationshistogram calculationdata validationVO service accessA powerful and extensible expression language is used for specifying data calculations. These facilities can be put together in very flexible and efficient ways. For tasks in which the data can be streamed, the size of table STILTS can process is effectively unlimited. For other tasks, million-row tables usually do not present a problem. STILTS is written in pure Java (J2SE1.5 or later), and can be run from the command line or from Jython, or embedded into java applications. It is released under the GPL.

    In the summer of 2010, soaring temperatures and widespread forest fires ravaged western Russia, killing 55,000 and causing $15 billion in economic losses. In the wake of the record-setting heat wave, two studies sought to identify the contribution that human activities made to the event. One showed that temperatures seen during the deadly heat wave fell within the bounds of natural variability, while another attributed the heat wave to human activity, arguing that anthropogenic warming increased the chance of record-breaking temperatures occurring. Merging the stances of both studies, Otto et al. sought to show that while human contributions to climate change did not necessarily cause the deadly heat wave, they did play a role in setting the stage for its occurrence. Using an ensemble of climate simulations, the authors assessed the expected magnitude and frequency of an event like the 2010 heat wave under both 1960s and 2000s environmental conditions. The authors found that although the average temperature in July 2010 was 5°C higher than the average July temperature from the past half decade, the deadly heat wave was within the natural variability of 1960s, as well as 2000s, climate conditions

    2006-05-08

    A key step in applying land surface parameterization schemes is to estimate model parameters that vary spatially and are unique to each computational element. Improved methods for parameter estimation (especially for parameters important to runoff response) are needed and require data from a wide range of climate regimes throughout the world. Accordingly, the GEWEX Hydrometeorology Panel (GHP) endorsed the concept of an international Model Parameter Estimation Project (MOPEX) at its Toronto meeting, August 1996. Phase I of MOPEX was funded by NOAA in FY 1997, Phase II in FY 2000 and Phase III in FY 2003. MOPEX was adopted as projects of the IAHS/WMO Committee on GEWEX and of the WMO Commission on Hydrology (CHy) and now is a contributor to the Combine Enhanced Observing Period (CEOP) of the World Climate Research Program (WCRP). In 2004 MOPEX became a Working Group of the IAHS Prediction for Ungaged Basins (PUB) Initiative. MOPEX also is expected to contribute to the work of the Hydrologic Ensemble Prediction Experiment (HEPEX) (Franz et al, 2005). The primary goal of MOPEX is to develop techniques for the a priori estimation of the parameters used in land surface parameterization schemes of atmospheric models and in hydrologic models. A major early effort of MOPEX has been to assemble a large number of high quality historical hydrometeorological and river basin characteristics data sets for a wide range of river basins (500-10,000 km{sup 2}) throughout the world. MOPEX data sets are available via the Internet (ftp://hydrology.nws.noaa.gov). This paper documents the development of data sets for U.S. river basins. Several highly successful parameter estimation workshops have been organized by MOPEX. The first was held as part of the IAHS meeting in Birmingham, England in July, 1999. The second workshop was hosted April, 2002 in Tucson, AZ by SAHRA/University of Arizona. The third MOPEX workshop was held as part of the IAHS meeting in Sapporo, July, 2003. The fourth

    2005-09-01

    We have developed a novel approach for undergraduate laboratory education termed "interlaboratory collaboration" in which students in distinct laboratory courses are responsible for different aspects of a single project that spans these courses. This approach attempts to model the industrial workplace where separate groups are responsible for different aspects of a project. By having students synthesize or study a set of different compounds the students within a class can compare their data and investigate trends in chemical reactivity or physical properties. Students enrolled in both an inorganic synthesis and a physical chemistry laboratory course concurrently are assigned compounds to analyze that they did not synthesize. At the end of this process students share their findings with their peers. The approach has been well received by students and faculty, alike.

    The authors have developed a technique for uranium isotope ratio measurements of powder samples in field settings. Such a method will be invaluable for environmental studies, radioactive waste operations, and decommissioning and decontamination operations. Immediate field data can help guide an ongoing sampling campaign. The measurement encompasses glow discharge sputtering from pressed sample hollow cathodes, high resolution laser spectroscopy using conveniently tunable diode lasers, and optogalvanic detection. At 10% {sup 235}U enrichment and above, the measurement precision for {sup 235}U/({sup 235}U+{sup 238}U) isotope ratios was {+-}3%; it declined to {+-}15% for 0.3% (i.e., depleted) samples. A prototype instrument was constructed and is described.

  16. Earth's glacial record and its tectonic setting

    NASA Astrophysics Data System (ADS)

    Eyles, N.

    1993-09-01

    Glaciations have occurred episodically at different time intervals and for different durations in Earth's history. Ice covers have formed in a wide range of plate tectonic and structural settings but the bulk of Earth's glacial record can be shown to have been deposited and preserved in basins within extensional settings. In such basins, source area uplift and basin subsidence fulfill the tectonic preconditions for the initiation of glaciation and the accomodation and preservation of glaciclastic sediments. Tectonic setting, in particular subsidence rates, also dictates the type of glaciclastic facies and facies successions that are deposited. Many pre-Pleistocene glaciated basins commonly contain well-defined tectonostratigraphic successions recording the interplay of tectonics and sedimentation; traditional climatostratigraphic approaches involving interpretation in terms of either ice advance/retreat cycles or glacio-eustatic sea-level change require revision. The direct record of continental glaciation in Earth history, in the form of classically-recognised continental glacial landforms and "tillites", is meagre; it is probable that more than 95% of the volume of preserved "glacial" strata are glacially-influenced marine deposits that record delivery of large amounts of glaciclastic sediment to offshore basins. This flux has been partially or completely reworked by "normal" sedimentary processes such that the record of glaciation and climate change is recorded in marine successions and is difficult to decipher. The dominant "glacial" facies in the rock record are subaqueous debris flow diamictites and turbidites recording the selective preservation of poorly-sorted glaciclastic sediment deposited in deep water basins by sediment gravity flows. However, these facies are also typical of many non-glacial settings, especially volcanically-influenced environments; numerous Archean and Proterozoic diamictites, described in the older literature as tillites, have no

    2009-01-01

    Communication research and investigations into the delivery of bad news are uncommon in psychiatry versus other medical specialties. The question of delivering "bad" diagnostic news in psychiatry has been focused on dementia rather than actual psychiatric disorders and their sequelae. Common problems are that psychiatrists avoid dealing with patients' emotional reactions to bad news and that they avoid providing a clear diagnosis for fear that patients or carers will be distressed. This article aims to provide an overview of key elements of the "breaking bad news" literature, teasing out factors that are relevant to psychiatric practice. Topics explored include: definitions; clinical considerations for delivering difficult news within medical and psychiatric settings; protocols and guidelines; evidence about patient information needs and communication preferences; research into actual delivery of such news; and areas for future education and research.

    In this study the structure tensor technique is used to estimate dynamical parameters in atmospheric data sets. The structure tensor is a common tool for estimating motion in image sequences. This technique can be extended to estimate other dynamical parameters such as diffusion constants or exponential decay rates. A general mathematical framework was developed for the direct estimation of the physical parameters that govern the underlying processes from image sequences. This estimation technique can be adapted to the specific physical problem under investigation, so it can be used in a variety of applications in trace gas, aerosol, and cloud remote sensing. As a test scenario this technique will be applied to modeled dust data. In this case vertically integrated dust concentrations were used to derive wind information. Those results can be compared to the wind vector fields which served as input to the model. Based on this analysis, a method to compute atmospheric data parameter fields will be presented. .

    Nowadays, there are a very large number of patients that need specific health support at home. The deployment of broadband communication networks is making feasible the provision of home care services with a proper quality of service. This paper presents a telehomecare multimedia platform that runs over integrated services digital network and internet protocol using videoconferencing standards H.320 and H.323, and standard TV set for patient interaction. This platform allows online remote monitoring: ECG, heart sound, blood pressure. Usability, affordability, and interoperability were considered for the design and development of its hardware and software components. A first evaluation of technical and usability aspects were carried forward with 52 patients of a private clinic and 10 students in the University. Results show a high rate (mean = 4.33, standard deviation--SD = 1.63 in a five-points Likert scale) in the global perception of users on the quality of images, voice, and feeling of virtual presence.

    2015-04-10

    We apply the BLM scale setting procedure directly to amplitudes (cross sections) of several semihard processes. It is shown that, due to the presence of β{sub 0}-terms in the NLA results for the impact factors, the obtained optimal renormalization scale is not universal, but depends both on the energy and on the process in question. We illustrate this general conclusion considering the following semihard processes: (i) inclusive production of two forward high-p{sub T} jets separated by large interval in rapidity (Mueller-Navelet jets); (ii) high-energy behavior of the total cross section for highly virtual photons; (iii) forward amplitude of the production of two light vector mesons in the collision of two virtual photons.

    2002-09-01

    The performance of ``typical set (pairs) decoding'' for ensembles of Gallager's linear code is investigated using statistical physics. In this decoding method, errors occur, either when the information transmission is corrupted by atypical noise, or when multiple typical sequences satisfy the parity check equation as provided by the received corrupted codeword. We show that the average error rate for the second type of error over a given code ensemble can be accurately evaluated using the replica method, including the sensitivity to message length. Our approach generally improves the existing analysis known in the information theory community, which was recently reintroduced in IEEE Trans. Inf. Theory 45, 399 (1999), and is believed to be the most accurate to date.

    Yip, Justin; van Hentenryck, Pascal; Gervet, Carmen

    This paper reconsiders the deployment of synchronous optical networks (SONET), an optimization problem naturally expressed in terms of set variables. Earlier approaches, using either MIP or CP technologies, focused on symmetry breaking, including the use of SBDS, and the design of effective branching strategies. This paper advocates an orthogonal approach and argues that the thrashing behavior experienced in earlier attempts is primarily due to a lack of pruning. It studies how to improve domain filtering by taking a more global view of the application and imposing redundant global constraints. The technical results include novel hardness results, propagation algorithms for global constraints, and inference rules. The paper also evaluates the contributions experimentally by presenting a novel model with static symmetric-breaking constraints and a static variable ordering which is many orders of magnitude faster than existing approaches.

    Gate set tomography (GST) is a method for characterizing quantum gates that does not require pre-calibrated operations, and has been used to both certify and improve the operation of single qubits. We analyze the performance of GST applied to a simulated two-qubit system, and show that Heisenberg scaling is achieved in this case. We present a GST analysis of preliminary two-qubit experimental data, and draw comparisons with the simulated data case. Finally, we will discuss recent theoretical developments that have improved the efficiency of GST estimation procedures, and which are particularly beneficial when characterizing two qubit systems.

    This document provides the calculations used to determine the error of safety class signals used for the CVD process These errors are used with the Parameter limits to arrive at the initial set point. The Safety Class Instrumentation and Control (SCIC) system provides active detection and response to process anomalies that, if unmitigated would result in a safety event. Specifically actuation of the SCIC system includes two portions. The portion which isolates the MCO and initiates the safety-class helium (SCHe) purge, and the portion which detects and stops excessive heat input to the MCO on high tempered water MCO inlet temperature. For the MCO isolation and purge the SCIC receives signals from MCO pressure (both positive pressure and vacuum) helium flow rate, bay high temperature switches, seismic trips and time under vacuum trips.

    The "Westland" set of empirical accelerometer helicopter data with seeded and labeled faults is analyzed with the aim of condition monitoring. The autoregressive (AR) coefficients from a simple linear model encapsulate a great deal of information in a relatively few measurements; and it has also been found that augmentation of these by harmonic and other parameters call improve classification significantly. Several techniques have been explored, among these restricted Coulomb energy (RCE) networks, learning vector quantization (LVQ), Gaussian mixture classifiers and decision trees. A problem with these approaches, and in common with many classification paradigms, is that augmentation of the feature dimension can degrade classification ability. Thus, we also introduce the Bayesian data reduction algorithm (BDRA), which imposes a Dirichlet prior oil training data and is thus able to quantify probability of error in all exact manner, such that features may be discarded or coarsened appropriately.

  6. Biclustering Bioinformatics Data Sets:. a Possibilistic Approach

    2007-12-01

    The analysis of genomic data from DNA microarray can produce a valuable information on the biological relevance of genes and on correlations among them. In the last few years some biclustering techniques have been proposed and applied to this analysis. Biclustering is a learning task for finding clusters of samples possessing similar characteristics together with features creating these similarities. When applied to genomic data it can allow us to identify genes with similar behavior with respect to different conditions. In this paper a new approach to the biclustering problem will be introduced extending the Possibilistic Clustering paradigm. The proposed Possibilistic Biclustering algorithm finds one bicluster at a time, assigning a membership to the bicluster for each gene and for each condition. Some results on oligonucleotide microarray data sets will be presented and compared with those obtained using other biclustering methods.

    A study was conducted to develop mass efficient composite struts. A closed-form design methodology for composite struts was developed using well established analyses to predict Euler buckling, local wall buckling; compression strength, damage tolerance, and interlaminar shear at geometric gradients. The methodology was coded in a spreadsheet suitable for convenient and rapid sizing of tapered composite struts. This spreadsheet analysis was used to determine the influence of several variables such as material stiffness, strut diameter, and material allowables on strut weight for given loading conditions. The comparison showed that, while the Park Aerospace design method was well suited to preliminary sizing for a conservative design, the closed-form-analyses-based spreadsheet accounts for all possible failure modes and is a good optimum strut design tool. The report concludes with a set of recommendations for future work in analytical design and analysis methodology enhancements.

    A study was conducted to identify the most important competencies physician executives in medical groups and other ambulatory settings will need to have in the next five years. The specific job skills, knowledge, and abilities (SKA) that physician executives will need to acquire these competencies were also explored. The Delphi techniques were used to analyze responses from two surveys from members of the American College of Medical Practice Executives. The most important competencies were grouped into 13 management domains, each with specific SKAs. "Managing health care resources to create quality and value" and "fundamentals of business and finance" were rated as the most important competencies. The most frequently rated SKA was the "ability to build and maintain credibility and trust." PMID:10185642

    The visualisation of three-dimensional objects on two dimensions is a very common problem, but is a tricky one to solve. Every discipline has its way of solving it. The artist uses light-shade interaction, perspective, special colour coding. The architect produces projections of the object. The cartographer uses both colour-coding and shading to represent height elevations. There have been many attempts in the last century by the entertainment industry to produce a three-dimensional illusion, in the fifties it was fashionable to have 3d movies which utilize the anaglyph method. Nowadays one can buy "Magic Eye" postcards which show a hidden three dimensional picture if you stare at it half cross-eyed. This poster attempts to demonstrate how some of these techniques can be applied to three-dimensional data sets that can occur in solar physics.

    Although the availability of oral contraceptives and the development of improved intrauterine contraceptive devices have greatly increased the general utilization of family planning services, there are still great segments of our population which are not yet reached, especially in the economically deprived areas. Since over 98 percent of all obstetrical deliveries now occur in hospitals, it seems logical that it is on hospital maternity services that these deficiencies might often be best overcome. Although this is primarily a medical problem, the use of paramedical personnel can greatly augment the physician's practice in these areas. Family planning services should be an integral part of comprehensive maternity care, not alone in the physician's office but also in the hospital setting. PMID:5784113

    Increased emphasis on routine screening of chemicals for potential neurotoxicity has resulted in the development of testing guidelines and standardized procedures. A multiphased, tiered-testing strategy has been proposed by numerous expert panels to evaluate large numbers of chemicals. In a regulatory context, however, a formal tiered-testing approach is not used, mostly because of the constraints of differing regulatory authorities and the potential cost of such a testing strategy. Instead, current regulatory decision making utilizes all available animal and human data to identify a critical adverse effect which is then used for setting standards. Although the current decision-making process does not use a formal tiered-testing approach, it appears to identify chemicals with neurotoxic effects. An analysis of U.S. Environmental Protection Agency integrated risk information system (IRIS) indicates that about 20% of the chemicals having standards or health advisories are based on neurotoxicity.

    There is an obvious trend towards developing ambulatory procedures in gynaecology with ambulatory hysteroscopy as its mainstay. In the recent years, the fast pace of modern technological advances in gynaecologic endoscopy, and particularly in the field of hysteroscopy, have been both thrilling and spectacular. Despite this, the uptake of operative hysteroscopy in ambulatory settings has been relatively slow. There is some apprehension amongst gynaecologists to embark on therapeutic outpatient hysteroscopy, and an organisational change is required to alter the mindset. Although there are best practice guidelines for outpatient hysteroscopy, there are unresolved issues around adequate training and accreditation of future hysteroscopists. Virtual-reality simulation training for operative hysteroscopy has shown promising preliminary results, and it is being aggressively evaluated and validated. This review article is an attempt to provide a useful practical guide to all those who wish to implement ambulatory hysteroscopy services in their outpatient departments. PMID:25979350

    To compare the effects of an acute one versus three-set full body resistance training (RT) bout in eight overweight (mean ± SD, BMI = 25.6 ± 1.5 kg m−2) young (21.0 ± 1.5 years) adults on resting energy expenditure (REE) measured on four consecutive mornings following each protocol. Participants performed a single one-set or three-set whole body (10 exercises, 10 repetition maximum) RT bout following the American College of Sports Medicine (ACSM) guidelines for RT. REE and respiratory exchange ratio (RER) by indirect calorimetry were measured at baseline and at 24, 48, and 72 h after the RT bout. Participants performed each protocol in randomized, counterbalanced order separated by 7 days. There was no difference between protocols for REE or RER. However, REE was significantly (p < 0.05) elevated (~5% or ~ 400 kJ day−1) in both the protocols at 24, 48, and 72 h post RT bout compared with baseline. There was a no change in RER in both the protocols at 72 h compared to baseline. A one-set RT bout following the ACSM guidelines for RT and requiring only ~ 15 min to complete was as effective as a three-set RT bout (~ 35 min to complete) in elevating REE for up to 72 h post RT in overweight college males, a group at high risk of developing obesity. The one-set RT protocol may provide an attractive alternative to either aerobic exercise or multiple-set RT programs for weight management in young adults, due to the minimal time commitment and the elevation in REE post RT bout.

    2014-01-01

    The use of analogy is an important component of human cognition. The type of analogy we produce and communicate depends heavily on a number of factors, such as the setting, the level of domain expertise present, and the speaker's goal or intent. In this observational study, we recorded economics experts during scientific discussion and examined the categorical distance and structural depth of the analogies they produced. We also sought to characterize the purpose of the analogies that were generated. Our results supported previous conclusions about the infrequency of superficial similarity in subject-generated analogs, but also showed that distance and depth characteristics were more evenly balanced than in previous observational studies. This finding was likely due to the nature of the goals of the participants, as well as the broader nature of their expertise. An analysis of analogical purpose indicated that the generation of concrete source examples of more general target concepts was most prevalent. We also noted frequent instances of analogies intended to form visual images of source concepts. Other common purposes for analogies were the addition of colorful speech, inclusion (i.e., subsumption) of a target into a source concept, or differentiation between source and target concepts. We found no association between depth and either of the other two characteristics, but our findings suggest a relationship between purpose and distance; i.e., that visual imagery typically entailed an outside-domain source whereas exemplification was most frequently accomplished using within-domain analogies. Overall, we observed a rich and diverse set of spontaneously produced analogical comparisons. The high degree of expertise within the observed group along with the richly comparative nature of the economics discipline likely contributed to this analogical abundance. PMID:25505437

    The filtering of potential policy issues from a large range of possibilities to a relatively small list of agenda items allows the organisation of power and influence within a policy sector to be examined. This study investigated power and influence in health policy agenda-setting in one State of Australia (Victoria) in the years 1991, 1992 and 1993. The actors seen as influential were predominantly medically trained and working in academia, health bureaucracies and public teaching hospitals. This research supports an elite model of health policy agenda-setting, in which outcomes are dependent on the structured interests within the policy field. However, while the corporate elite of the profession is influential, the frontline service providers are not, as indicated by the location of influentials in large and prestigious organisations. Politicians and professional associations and unions are less well represented, and consumer and community groups are virtually absent. In 1993 there was a sharp increase in economists being nominated as influentials, with a subsequent decrease in influentials with medical training. This relates to a (perceived or real) shift in influence from the medical profession to senior health bureaucrats. Economic concerns appear to be shaping the visible health policy agenda, through an increased number of influentials with economics training, but also through an apparent ability to shape the issues that other influentials are adding as agenda items. The corporate elite of medicine remains powerful, but their range of concerns has been effectively limited to cost containment or cost reduction, better planning and efficiency. This limiting of concerns occurs within an international policy context, where the general trends of globalisation and an emphasis on neo-liberal economics impact on the direction of health policy in individual countries.

  16. Bayesian photometric redshifts with empirical training sets

    NASA Astrophysics Data System (ADS)

    Wolf, Christian

    2009-07-01

    We combine in a single framework the two complementary benefits of χ2 template fits and empirical training sets used e.g. in neural nets: χ2 is more reliable when its probability density functions (PDFs) are inspected for multiple peaks, while empirical training is more accurate when calibration and priors of query data and training set match. We present a χ2 empirical method that derives PDFs from empirical models as a subclass of kernel regression methods, and apply it to the Sloan Digital Sky Survey Data Release 5 sample of >75000 quasi-stellar objects, which is full of ambiguities. Objects with single-peak PDFs show <1 per cent outliers, rms redshift errors <0.05 and vanishing redshift bias. At z > 2.5, these figures are two times better. Outliers result purely from the discrete nature and limited size of the model, and rms errors are dominated by the intrinsic variety of object colours. PDFs classed as ambiguous provide accurate probabilities for alternative solutions and thus weights for using both solutions and avoiding needless outliers. E.g. the PDFs predict 78.0 per cent of the stronger peaks to be correct, which is true for 77.9 per cent of them. Redshift incompleteness is common in faint spectroscopic surveys and turns into a massive undetectable outlier risk above other performance limitations, but we can quantify residual outlier risks stemming from size and completeness of the model. We propose a matched χ2 error scale for noisy data and show that it produces correct error estimates and redshift distributions accurate within Poisson errors. Our method can easily be applied to future large galaxy surveys, which will benefit from the reliability in ambiguity detection and residual risk quantification.

    Energetic electron (30-15000 keV) and proton 145 keV to 150 MeV) measurements made by Los Alamos National Laboratory sensors at geostationary orbit (6.6 R/sub E/) are summarized. The instrumentation employed and the satellite positions are described. The spacecraft have been variously located, but in their present configuration the Los Alamos satellites designated 1976-059, 1977-007, and 1979-053 are located, respectively, at approx. 70/sup 0/W, approx. 70/sup 0/E, and approx. 135/sup 0/W longitude. Several examples of the high temporal and full three-dimensional spatial measurement capabilities of these instruments are illustrated by examples from the published literature. Discussion is also given for the Los Alamos Synoptic Data Set (SDS) which gives a broad overview of the Los Alamos geostationary orbit measurements. The SDS data are plotted in terms of daily average spectra, 3-hour local time averages, and in a variety of statistical formats. The data summarize conditions from mid-1976 through 1978 (S/C 1976-059) and from early 1977 through 1978 (S/C 1977-007). The SDS compilations presented correspond to measurements at 35/sup 0/W, 70/sup 0/W, and 135/sup 0/W geographic longitude and thus are indicative of conditions at 9/sup 0/, 11/sup 0/, and 4.8/sup 0/ geomagnetic latitude, respectively. The bulk of the SDS report presents data plots which are organized according to Carrington solar rotations and, as such, the data are readily comparable to solar rotation-dependent interplanetary conditions. Potential applications of the Synoptic Data Set (available to all interested users in June 1981) are discussed.

  18. Many-Body Basis Set Superposition Effect.

    2015-11-10

    The basis set superposition effect (BSSE) arises in electronic structure calculations of molecular clusters when questions relating to interactions between monomers within the larger cluster are asked. The binding energy, or total energy, of the cluster may be broken down into many smaller subcluster calculations and the energies of these subsystems linearly combined to, hopefully, produce the desired quantity of interest. Unfortunately, BSSE can plague these smaller fragment calculations. In this work, we carefully examine the major sources of error associated with reproducing the binding energy and total energy of a molecular cluster. In order to do so, we decompose these energies in terms of a many-body expansion (MBE), where a "body" here refers to the monomers that make up the cluster. In our analysis, we found it necessary to introduce something we designate here as a many-ghost many-body expansion (MGMBE). The work presented here produces some surprising results, but perhaps the most significant of all is that BSSE effects up to the order of truncation in a MBE of the total energy cancel exactly. In the case of the binding energy, the only BSSE correction terms remaining arise from the removal of the one-body monomer total energies. Nevertheless, our earlier work indicated that BSSE effects continued to remain in the total energy of the cluster up to very high truncation order in the MBE. We show in this work that the vast majority of these high-order many-body effects arise from BSSE associated with the one-body monomer total energies. Also, we found that, remarkably, the complete basis set limit values for the three-body and four-body interactions differed very little from that at the MP2/aug-cc-pVDZ level for the respective subclusters embedded within a larger cluster.

    Context This systematic review evaluated the evidence on the impact of contraceptive counseling provided in clinical settings on reproductive health outcomes to provide information to guide national recommendations on quality family planning services. Evidence acquisition Multiple databases were searched during 2010–2011 for peer-reviewed articles published in English from January 1985 through February 2011 describing studies that evaluated contraceptive counseling interventions in clinical settings. Studies were excluded if they focused primarily on prevention of HIV or sexually transmitted infections, focused solely on men, or were conducted outside the U.S., Canada, Europe, Australia, or New Zealand. Evidence synthesis The initial search identified 12,327 articles, of which 22 studies (from 23 articles) met the inclusion criteria. Six studies examined the impact of contraceptive counseling among adolescents, with four finding a significant positive impact on at least one outcome of interest. Sixteen studies examined the impact of counseling among adults or mixed populations (adults and adolescents), with 11 finding a significant positive impact on at least one outcome of interest. Conclusions Promising components of contraceptive counseling were identified despite the diversity of interventions and inability to compare the relative effectiveness of one approach versus another. The evidence base would be strengthened by improved documentation of counseling procedures; assessment of intervention implementation and fidelity to put study findings into context; and development and inclusion of more RCTs, studies conducted among general samples of women, and studies with sample sizes sufficient to detect important behavioral outcomes at least 12 months post-intervention.
