  2. THE LINDA CRANE MEMORIAL LECTUR

    PubMed Central

    2011-01-01

    At 90 years of age, the APTA may be facing some of the greatest national and global challenges of its history. Membership has grown from 238 in 1921 to over 70,000 in 2011, but the expansion of the APTA may be restrictive to individual participation. A leadership gap appears imminent in practice and education. Fostering every member to understand the APTA and its great work is essential to ensuring a profession that lives its core values and meets societal needs. The Linda Crane Memorial Lecture in 2011 celebrated a vision of the APTA's 100th birthday with every member serving as a “professional centenarian” who stewards the organization to continued greatness.

  3. Ruptures of vulnerability: Linda Stein's Knight Series.

    PubMed

    Bible, Ann Vollmann

    2010-01-01

    Drawing on the work of Monique Wittig, this article understands Linda Stein's Knight Series as a lacunary writing communicating both her challenges to come to representation and her creative registration of subjectivity. The argument is grounded in an exploration of the rich interplay of power and vulnerability across the series as against the discourse of escapist fashion. Specifically, Stein's critical contradictions of inside and outside, conflated temporality, disjunctions between decoration and abstraction, and fluidity of sex and gender are examined. The discussion is elaborated through consideration of the work of Julia Kristeva, Elizabeth Grosz, and Hayao Miyazaki.

    In April 1986, officials of Loma Linda University requested that Fermilab design and construct a 250 MeV proton synchrotron for radiotherapy, to be located at the Loma Linda University Medical Center. In June 1986 the project, having received all necessary approvals, commenced. In order to meet a desirable schedule providing for operation in early 1990, it was decided to erect such parts of the accelerator as were complete at Fermilab and conduct a precommissioning activity prior to the completion of the building at Loma Linda which will house the final radiotherapy facility. It was hoped that approximately one year would be saved by the precommissioning, and that important information would be obtained about the system so that improvements could be made during installation at Loma Linda. This report contains an analysis by Fermilab staff members of the information gained in the precommissioning activity and makes recommendations about steps to be taken to enhance the performance of the proton synchrotron at Loma Linda. In the design of the accelerator, effort was made to employ commercially available components, or to industrialize the products developed so that later versions of the accelerator could be produced industrially. The magnets could only be fabricated at Fermilab if the schedule was to be met, but efforts were made to transfer that technology to industry. Originally, it was planned to use a 1.7 MeV RFQ fabricated at the Lawrence Berkeley Laboratory as injector, but LBL would have found it difficult to meet the project schedule. After consideration of other options, for example a 3.4 MeV tandem accelerator, a supplier (AccSys Inc.) qualified itself to provide a 2 MeV RFQ on a schedule well matched to the project schedule. This choice was made, but a separate supplier was selected to develop and provide the 425 MHz power amplifier for the RFQ.

    2010-01-01

    Historically, invited lecturers have often challenged us to define excel lence in physical therapy practice, or in our academic programs. While some have addressed different char acteristics of excellence, our profession has not really come together to address 2 very important questions: what does “quality” mean in physical therapist education? And how do we measure it? Using 3 elements of Friendship, Leadership, and Mentoring, and Defining Excellence and juxtaposing these with Linda Crane and her life, a vision of excellence in physical therapy educational programs was explored in this invited lecture. The text of that lecture ensues. PMID:20520760

    Coutrakon, George; Ghebremedhin, Abiel

    1999-06-01

    More than eight years have passed since Loma Linda University Medical Center treated its first cancer patient with the world's first hospital based proton therapy accelerator. Using a synchrotron with extracted energies in the range of 70 to 250 MeV, nearly one hundred patients per day have been treated at the facility. Over the past five years, more than 97% of the patients received treatments on the day they were scheduled for irradiation. The activity schedules of accelerator maintenance and operations to maintain this patient load and accelerator reliability are presented in this paper. A typical 24-hour schedule of daily beam activities is presented. The specifications of what was needed in 1990 and what is needed now will also be discussed, as will an accelerator control system upgrade for achieving better intensity and energy control for more advanced dose localization. These new requirements include rapid energy and intensity changes within a patient treatment, fast beam abort systems, uniform beam spill, and energy control to better than 0.1%.

    2016-04-01

    The gold standard for identifying stroke lesions is manual tracing, a method that is known to be observer dependent and time consuming, thus impractical for big data studies. We propose LINDA (Lesion Identification with Neighborhood Data Analysis), an automated segmentation algorithm capable of learning the relationship between existing manual segmentations and a single T1-weighted MRI. A dataset of 60 left hemispheric chronic stroke patients is used to build the method and test it with k-fold and leave-one-out procedures. With respect to manual tracings, predicted lesion maps showed a mean dice overlap of 0.696 ± 0.16, Hausdorff distance of 17.9 ± 9.8 mm, and average displacement of 2.54 ± 1.38 mm. The manual and predicted lesion volumes correlated at r = 0.961. An additional dataset of 45 patients was utilized to test LINDA with independent data, achieving high accuracy rates and confirming its cross-institutional applicability. To investigate the cost of moving from manual tracings to automated segmentation, we performed comparative lesion-to-symptom mapping (LSM) on five behavioral scores. Predicted and manual lesions produced similar neuro-cognitive maps, albeit with some discussed discrepancies. Of note, region-wise LSM was more robust to the prediction error than voxel-wise LSM. Our results show that, while several limitations exist, our current results compete with or exceed the state-of-the-art, producing consistent predictions, very low failure rates, and transferable knowledge between labs. This work also establishes a new viewpoint on evaluating automated methods not only with segmentation accuracy but also with brain-behavior relationships. LINDA is made available online with trained models from over 100 patients. PMID:26756101

    2010-05-01

    The Bergen Arc, western Norway is composed of several units distributed in an arc shape. Lindas Nappe is one of these units. Two peridotite outcrops in Lindas Nappe anorthosite complex were studied to understand deformation conditions of olivine. A mylonite zone was found in the peridoties and deformation fabrics of small olivine in the area were also studied. Lattice preferred orientation (LPO) of olivine was determined using the electron backscattered diffraction (EBSD) in SEM. Water content of olivine in the samples was measured using the Fourier transformation infrared (FTIR) spectroscopy. We observed three different types of LPOs (E-, B-, and A-type) of olivine in a large grain area. Sample (372) showed that [100] axes of olivine are aligned subparallel to the lineation and [001] axes aligned normal to the foliation, which is known as E-type LPO of olivine (Jung et al., 2006). Three samples (375, 380, and 381) showed that [001] axes of olivine are aligned subparallel to the lineation and [010] axes aligned normal to the foliation, which is known as B-type LPO of olivine. Another sample (379) in the large grain area showed that [100] axes of olivine are aligned subparallel to the lineation and [010] axes aligned normal to the foliation, which is known as A-type LPO of olivine. On the other hand, we observed two types of LPOs of olivine in a mylonite zone with a small grain-size: B- and C-type. C-type LPO is characterized as [001] axes of olivine aligned subparallel to the lineation and [100] axes of olivine aligned nearly normal to the foliation. Previous experimental study showed that B-, C-, and E-type LPO patterns were observed in a wet condition and A-type LPO was observed in a dry condition (Jung et al., 2006). FTIR analysis of olivine revealed that a sample showing the A-type LPO showed only small IR absorption peaks in the range of wave numbers 3000 - 3750 cm-1. In contrast, samples showing B-, C-, and E-type LPO showed large IR absorption peaks in the

    The article details an interview with activist Linda Grinberg of Foundation for AIDS and Immune Research (FAIR) on the activities of the Coalition for Salvage Therapy (CST), advocates for persons with advanced HIV infection and multiple treatment failures; CST seeks to improve research, and promote the earliest possible access to drugs for patients who urgently need new treatments. Although heavily pre-treated or multi-drug resistant patients appear to be the most realistic test for new drugs, companies often recruit treatment-naive patients, where success may be more easily shown. By working with pharmaceutical companies to persuade them to conduct trials such as "proof of concept" studies, CST and other groups are trying to improve treatment for persons with HIV infection.

    The Loma Linda University (LLU) Radiobiology Program coordinates basic research and proton beam service activities for the university and extramural communities. The current focus of the program is on the biological and physical properties of protons and the operation of radiobiology facilities for NASA-sponsored projects. The current accelerator, supporting facilities and operations are described along with a brief review of extramural research projects supported by the program. These include space craft electronic parts and shielding testing as well as tumorigenesis and animal behavior experiments. An overview of research projects currently underway at LLU is also described. These include: 1) acute responses of the C57Bl/6 mouse immune system, 2) modulation of gene expression in the nematode C. elegans and rat thyroid cells, 3) quantitation of dose tolerance in rat CNS microvasculature, 4) behavioral screening of whole body proton and iron ion-irradiated C57Bl/6 mice, and 5) investigation of the role of cell integration into epithelial structures on responses to radiation.

  8. Improving tobacco dependence education among the Loma Linda University School of Dentistry faculty.

    PubMed

    Arnett, Margie R; Baba, Nadim Z

    2011-06-01

    Tobacco-related health problems are among the most preventable forms of illness. By assuming proactive tobacco use counseling roles, dental professionals can help reduce the number of people who use tobacco. Minimum standards for intervention by dental care providers were established more than a decade ago by the American Dental Association and the American Dental Hygienists' Association. The goal of Loma Linda University School of Dentistry in its tobacco-cessation efforts is to move beyond those standards towards more effective interventions. The school conducted a study to determine the formal education of the faculty, evaluate the current state of tobacco dependence education (TDE) delivered to students, identify topics that dental faculty members wanted to further their education, promote tobacco dependence education among the dental faculty, and enhance teaching moments on the clinic floor. A fifty-seven question survey was e-mailed to all faculty members with >0.4 FTE (full-time equivalent) during the 2007-08 school year. The response rate was 80 percent (101 out of 126). The results revealed that faculty members have limited formal training; however, 73.1 percent agreed that TDE would be beneficial to them. They also believed that, upon graduation, dental professionals should be able to perform at least a ten-minute moderate intervention program and discuss options for tobacco dependence treatments with patients. This project was designed to establish a 2008-09 baseline of TDE clinical practices, knowledge, and attitudes and to assess the effects of faculty development, curricular didactic, and clinical changes.

  9. The Conjunction and Disjunction Fallacies: Explanations of the Linda Problem by the Equate-to-Differentiate Model.

    PubMed

    Lu, Yong

    2016-09-01

    We propose the use of the equate-to-differentiate model (Li, S. (2004), Equate-to-differentiate approach, Central European Journal of Operations Research, 12) to explain the occurrence of both the conjunction and disjunction fallacies. To test this model, we asked participants to judge the likelihood of two multi-statements and their four constituents in two modified versions of the Linda problem in two experiments. The overall results underpin this pragmatic model's inference and also reveal that (1) single conjunction and disjunction fallacies are most prevalent, (2) the incidence of the conjunction fallacy is proportional to the distance between the constituent probabilities, and (3) some participants misinterpreted A ∧ B either as ¬ A ∧ B or A ∨ B. The findings were generally consistent with the configural weighted average model (Nilsson, H., Winman, A., Juslin, P., & Hansson, G. (2009), Linda is not a bearded lady, Journal of Experimental Psychology: General, 138) and the potential surprise conceptual framework (Fisk, J. E.

    The vision of the School of Science and Technology (SST) at Loma Linda University (LLU) is to develop an interdisciplinary approach to doing science that bridges the social, biological, earth, and health sciences. It will provide opportunities for undergraduate, graduate, and professional students to apply new tools and concepts to the promotion of global service and citizenship while addressing issues of global poverty, health and disease, environmental degradation, poverty, and social inequality. A primary teaching strategy will be to involve students with faculty in applied field social and science policy research on "global sustainability" issues and problems in real places such as Fiji, Jamaica, Honduras, Bahamas, East Africa, and the US southwest (Great Basin, Salton Sea, coastal California, southern Utah). Recently we became a partner in the NASA/USRA ESSE21 Project (Earth System Science Education for the 21st Century). We bring to that consortium strengths and experience in areas such as social policy, sustainable development, medicine, environmental health, disaster mitigation, humanitarian relief, geoinformatics and bioinformatics. This can benefit ESSE21, the NASA Earth Enterprise Mission, and the wider geosciences education community by demonstrating the relevance of such tools, and methods outside the geosciences. Many of the graduate and undergraduate students who will participate in the new program come from around the world while many others represent underserved populations in the United States. The PI and Co-PIs have strong global as well as domestic experience serving underrepresented communities, e.g. Seth Wiafe from Ghana, Sam Soret from Spain, Stephen Dunbar from the South Pacific, and Robert Ford from Latin America and Africa. Our partnership in implementation will include other institutions such as: La Sierra University, the California State University, Pomona, Center for Geographic Information Science Research, ESRI, Inc., the University of

  12. Holocene Amazon rainforest-savanna dynamics and climatic implications: high-resolution pollen record from Laguna Loma Linda in eastern Colombia

    NASA Astrophysics Data System (ADS)

    Behling, Hermann; Hooghiemstra, Henry

    2000-10-01

    We present a high-resolution pollen record of a 695-cm-long sediment core from Laguna Loma Linda, located at an altitude of 310 m in the transitional zone between the savannas of the Llanos Orientales and the Amazonian rainforest, about 100 km from the Eastern Cordillera. Based on eight AMS 14C ages, the record represents the last 8700 14C yr BP. During the period from 8700 to 6000 14C yr BP the vegetation was dominated by grass savanna with only a few woody taxa, such as Curatella and Byrsonima, present in low abundance. Gallery forest along the drainage system apparently was poorly developed. Compared with today, precipitation must have been significantly lower and seasonality stronger. During the period from 6000 to 3600 14C yr BP, rainforest taxa increased markedly, reflecting an increase in precipitation. Rainforest and gallery forest taxa such as Moraceae/Urticaceae, Melastomataceae, Alchornea, Cecropia and Acalypha, were abundant, whereas Poaceae were reduced in frequency. From 3600 to 2300 14C yr BP rainforest taxa continued to increase; Moraceae/Urticaceae became very frequent, and Myrtaceae and Myrsine became common. Savanna vegetation decreased continuously. We infer that precipitation was still increasing, and that the length of the annual dry period possibly shortened. From 2300 14C yr BP onwards, grass savanna (mainly represented by Poaceae) expanded and Mauritia palms became frequent. This reflects increased human impact on the vegetation.

    KEY MESSAGE : The P ( SAG12 ) -ipt gene was transferred to miniature rose, as the first woody species, resulting in increased ethylene resistance due to specific up-regulation of the ipt gene under senescence promoting conditions. Transgenic plants of Rosa hybrida 'Linda' were obtained via transformation with Agrobacterium tumefaciens strain harboring the binary vector pSG529(+) containing the P( SAG12 )-ipt construct. A. tumefaciens strains AGL1, GV3850 and LBA4404 (containing P(35S)-INTGUS gene) were used for transformation of embryogenic callus, but transgenic shoots were obtained only when AGL1 was applied. The highest transformation frequency was 10 % and it was achieved when half MS medium was used for the dilution of overnight culture of Agrobacterium. Southern blot confirmed integration of 1-6 copies of the nptII gene into the rose genome in the tested lines. Four transgenic lines were obtained which were morphologically true-to-type and indistinguishable from Wt shoots while they were in in vitro cultures. Adventitious root induction was more difficult in transgenic shoots compared to the Wt shoots, however, one of the transgenic lines (line 6) was rooted and subsequently analyzed phenotypically. The ipt expression levels were determined in this line after exposure to exogenous ethylene (3.5 μl l(-1)) and/or darkness. Darkness resulted in twofold up-regulation of ipt expression, whereas darkness combined with ethylene caused eightfold up-regulation in line 6 compared to Wt plants. The transgenic line had significantly higher content of chlorophyll at the end of the treatment period compared to Wt plants.

    An urgent need exists for graduate and professional schools to establish evidence-based STEM (science, technology, engineering, and math) pipeline programs to increase the diversity of the biomedical workforce. An untapped yet promising pool of willing participants are capable high school students that have a strong STEM interest but may lack the skills and the guided mentoring needed to succeed in competitive STEM fields. This study evaluates and compares the impact of the Loma Linda University (LLU) Summer Health Disparities Research Program on high school (HS) and undergraduate (UG) student participants. The primary focus of our summer research experience (SRE) is to enhance the research self-efficacy of the participants by actively involving them in a research project and by providing the students with personalized mentoring and targeted career development activities, including education on health disparities. The results of our study show that our SRE influenced terminal degree intent and increased participant willingness to incorporate research into future careers for both the HS and the UG groups. The quantitative data shows that both the HS and the UG participants reported large, statistically significant gains in self-assessed research skills and research self-efficacy. Both participant groups identified the hands-on research and the mentor experience as the most valuable aspects of our SRE and reported increased science skills, increased confidence in science ability and increased motivation and affirmation to pursue a science career. The follow-up data indicates that 67% of the HS participants and 90% of the UG participants graduated from college with a STEM degree; for those who enrolled in graduate education, 61% and 43% enrolled in LLU, respectively. We conclude that structured SREs can be highly effective STEM strengthening interventions for both UG and HS students and may be a way to measurably increase institutional and biomedical workforce

  19. Sailors' scurvy before and after James Lind--a reassessment.

    PubMed

    Baron, Jeremy Hugh

    2009-06-01

    Scurvy is a thousand-year-old stereotypical disease characterized by apathy, weakness, easy bruising with tiny or large skin hemorrhages, friable bleeding gums, and swollen legs. Untreated patients may die. In the last five centuries sailors and some ships' doctors used oranges and lemons to cure and prevent scurvy, yet university-trained European physicians with no experience of either the disease or its cure by citrus fruits persisted in reviews of the extensive but conflicting literature. In the 20(th) century scurvy was shown to be due to a deficiency of the essential food factor ascorbic acid. This vitamin C was synthesized, and in adequate quantities it completely prevents and completely cures the disease, which is now rare. The protagonist of this medical history was James Lind. His report of a prospective controlled therapeutic trial in 1747 preceded by a half-century the British Navy's prevention and cure of scurvy by citrus fruits. After lime-juice was unwittingly substituted for lemon juice in about 1860, the disease returned, especially among sailors on polar explorations. In recent decades revisionist historians have challenged normative accounts, including that of scurvy, and the historicity of Lind's trial. It is therefore timely to reassess systematically the strengths and weaknesses of the canonical saga.

    This article explores the configural weighted average (CWA) hypothesis suggesting that extension biases, like conjunction and disjunction errors, occur because people estimate compound probabilities by taking a CWA of the constituent probabilities. The hypothesis suggests a process consistent with well-known cognitive constraints, which nonetheless achieves high robustness and bounded rationality in noisy real-life environments. Predictions by the CWA hypothesis are that in error-free data, conjunction and disjunction errors should be the rule rather than the exception when pairs of statements are randomly sampled from an environment, the rate of extension errors should increase when noise in data is decreased, and that adding a likely component should increase the probability of a conjunction. Four experiments generally verify the predictions by the hypothesis, demonstrating that extension errors are frequent also when tasks are selected according to representative design. PMID:19883134

    2003-08-01

    Beam scanning in proton therapy is a medical technique to lower the dose to healthy tissue while irradiating a tumor volume. Scanned proton beams for proton radiation therapy require small beam sizes at the tumor location. In beam scanning, a small beam usually less than 1 cm diameter is swept across the tumor volume with two magnets located several meters upstream of the patient. In general, all proton beams in a therapy facility must be transported from the accelerator to the treatment rooms where the scanning systems are located. This paper addresses the problem of transporting the beam without losses to the patient and achieving a small beam at the tumor location in the patient. The strengths of the beam line quadrupoles were allowed to vary to produce the desired beam sizes along the beam lines. Quadrupole strengths were obtained using the beam simulation program TRANSPORT originally from Stanford Linear Accelerator Center in Palo Alto, CA. An enhanced version of the original program by Accel Soft Inc. in San Diego, CA has been used for these studies. Beam size measurements were used for comparison with TRANSPORT to verify the predictions of TRANSPORT calculations.

    Water is arguably our most important natural resource, essential for sustaining life on Earth; necessary to support agriculture and industry; and important for fisheries, power, navigation, and recreation. As world population increases and climate change brings about a redistribution of water and people across our planet, water resource management and conservation are increasingly important. Based on current population projections for Texas, about 85 percent of the state’s projected population will not have enough water by 2060 in drought conditions. Water conservation is critical for meeting the state’s long-term water needs. To that end, the Texas Water Development Board (TWDB) is engaged in a number of education and outreach programs. In this paper, we report on three TWDB educational campaigns. Water Exploration, a Web-based water resources education program for Texas high school students, Put Some Blue in Your Green School, a service learning project designed to promote interaction between schools and their local communities, and Water IQ: Know Your Water, a public awareness campaign for water conservation. Water Exploration uses a pedagogical approach called the Legacy Cycle to involve students in experiential, project-based learning to help them achieve a deeper understanding about water resources. It addresses the need for rigorous curriculum in a vitally important area for the new Texas high school Earth and Space Science Capstone course, as well as Environmental Systems, and Aquatic Science. The interdisciplinary nature of the curriculum encourages students to explore the connections between water resources and economics (water planning, water as a commodity), history (water affects human settlement and migration), and biology (water is essential for life; contaminated water affects living organisms). The ability to integrate information from different disciplines and weigh the perspectives of multiple experts is particularly important for solving the complex problems in the geosciences (e.g. contaminant remediation, flood control, or climate change). Put Some Blue in Your Green School is a service learning program designed to engage students in real-world problem solving. Students form teams to collect and analyze indoor and outdoor water use data, and prepare recommendations for actions to help schools become efficient water users. By forming partnerships with water supply entities and other community members, students learn about the need for good stewardship practices for water resources and engage the community in understanding the need for conservation. Water IQ: Know your water, is a statewide public awareness campaign that educates Texans about water conservation. Through Water IQ, the Texas Water Development Board provides information on water-efficient practices raises the awareness about the importance of water conservation and helps Texans use less water. The program is designed to complement and support existing local and regional conservation efforts. Communities are encouraged to use Water IQ and provide a link from their community web site to the Water IQ web site.

    Purpose: We update our previous reports on the use of hypofractionated proton beam radiation therapy for early-stage lung cancer patients. Methods and Materials: Eligible subjects had biopsy-proven non-small cell carcinoma of the lung and were medically inoperable or refused surgery. Clinical workup required staging of T1 or T2, N0, M0. Subjects received hypofractionated proton beam therapy to the primary tumor only. The dose delivered was sequentially escalated from 51 to 60 Gy, then to 70 Gy in 10 fractions over 2 weeks. Endpoints included toxicity, pulmonary function, overall survival (OS), disease-specific survival (DSS), and local control (LC). Results: One hundred eleven subjects were analyzed for treatment outcomes. The patient population had the following average characteristics; age 73.2 years, tumor size 3.6 cm, and 1.33 L forced expiratory volume in 1 second. The entire group showed improved OS with increasing dose level (51, 60, and 70 Gy) with a 4-year OS of 18%, 32%, and 51%, respectively (P=.006). Peripheral T1 tumors exhibited LC of 96%, DSS of 88%, and OS of 60% at 4 years. Patients with T2 tumors showed a trend toward improved LC and survival with the 70-Gy dose level. On multivariate analysis, larger tumor size was strongly associated with increased local recurrence and decreased survival. Central versus peripheral location did not correlate with any outcome measures. Clinical radiation pneumonitis was not found to be a significant complication, and no patient required steroid therapy after treatment for radiation pneumonitis. Pulmonary function was well maintained 1 year after treatment. Conclusions: High-dose hypofractionated proton therapy achieves excellent outcomes for lung carcinomas that are peripherally or centrally located. The 70-Gy regimen has been adopted as standard therapy for T1 tumors at our institution. Larger T2 tumors show a trend toward improved outcomes with higher doses, suggesting that better results could be seen with intensified treatment.

    Abstract: Researchers, policymakers, business, and industry have indicated that the United States will experience a future shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this impending shortage, one of which includes increasing the representation of females and minorities in the STEM fields. In order to increase the representation of underrepresented students in the STEM fields, it is important to understand the motivational factors that impact underrepresented students' interest in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). In this paper, the mathematics research team examined the role of practical research experience during the summer for talented minority secondary students studying in STEM fields. An undergraduate research mathematics team focused on the link between summer research and the choice of an undergraduate discipline. A Chi Square Statistical Test was used to examine Likert Scale results on the attitude of students participating in the 2006-2012 Center for Remote Sensing of Ice Sheets (CReSIS) Summer Research Programs for secondary students. This research was performed at Elizabeth City State University located in northeastern North Carolina about the factors that impact underrepresented students' choices of STEM related majors in college. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of underrepresented students.

  14. An Extensible Space-Based Coordination Approach for Modeling Complex Patterns in Large Systems

    NASA Astrophysics Data System (ADS)

    Kühn, Eva; Mordinyi, Richard; Schreiber, Christian

    Coordination is frequently associated with shared data spaces employing Linda coordination. But in practice, communication between parallel and distributed processes is carried out with message exchange patterns. What, actually, do shared data spaces contribute beyond these? In this paper we present a formal representation for a definition of shared spaces by introducing an "extensible tuple model", based on existing research on Linda coordination, some Linda extensions, and virtual shared memory. The main enhancements of the extensible tuple model comprise: means for structuring of spaces, Internet- compatible addressing of resources, more powerful coordination capabilities, a clear separation of user data and coordination information, support of symmetric peer application architectures, and extensibility through programmable aspects. The advantages of the extensible tuple model (XTM) are that it allows for a specification of complex coordination patterns.

    Thirteen hadron beam therapy facilities began operation between 1990 and 2001 - 5 in Europe, 4 in North America, 3 in Japan, and 1 in South Africa [l]. Ten of them irradiate tumors with protons, 2 with Carbon- 12 ions, and 1 with both protons and Carbon-12. The facility with the highest patient throughput - a total of 6 174 patients in 11 years and as many as 150 patient treatments per day -is the Loma Linda University Medical Center, which uses a weak focusing slow cycling synchrotron to accelerate beam for delivery to passive scattering nozzles at the end of rotatable gantries [2, 3,4]. The Rapid Cycling Medical Synchrotron (RCMS) is a second generation synchrotron that, by contrast with the Loma Linda synchrotron, is strong focusing and rapid cycling, with a repetition rate of 30 Hz. Primary parameters for the RCMS are listed in Table 1.

    2005-01-01

    Dynamic property measurements of the moment-resisting steel-frame University of California, Los Angeles, Factor building are being made to assess how forces are distributed over the building. Fourier amplitude spectra have been calculated from several intervals of ambient vibrations, a 24-hour period of strong winds, and from the 28 March 2003 Encino, California (ML = 2.9), the 3 September 2002 Yorba Linda, California (ML = 4.7), and the 3 November 2002 Central Alaska (Mw = 7.9) earthquakes. Measurements made from the ambient vibration records show that the first-mode frequency of horizontal vibration is between 0.55 and 0.6 Hz. The second horizontal mode has a frequency between 1.6 and 1.9 Hz. In contrast, the first-mode frequencies measured from earthquake data are about 0.05 to 0.1 Hz lower than those corresponding to ambient vibration recordings indicating softening of the soil-structure system as amplitudes become larger. The frequencies revert to pre-earthquake levels within five minutes of the Yorba Linda earthquake. Shaking due to strong winds that occurred during the Encino earthquake dominates the frequency decrease, which correlates in time with the duration of the strong winds. The first shear wave recorded from the Encino and Yorba Linda earthquakes takes about 0.4 sec to travel up the 17-story building. ?? 2005, Earthquake Engineering Research Institute.

  8. The use of the analyst as an autistic shape.

    PubMed

    Power, Dolan

    2016-08-01

    In this paper I describe through detailed clinical material the challenges posed by patients who employ entangled autistic defenses. I discuss the complicated nature of treating a patient who employed entangled autistic defenses and utilized my voice in an effort to preserve an undifferentiated state of dual unity. My patient's pursuit of dual unity took a very concrete form in her attempt to mitigate the terror of separateness. This concreteness was expressed via the patient's urgent request that I read letters she wrote to me between sessions. This type of autistic defense placed great strain on my ability to think analytically and I also became increasingly concrete in my response to the patient. Crucial to the analyst's regaining a space in which to think and a sense of separateness is the ability to contact the ground floor of her separate bodily experience. This is just the beginning step in the analyst separating herself from the powerful press to join the patient in a state of dual unity. Interpretation in action (Ogden, 1994) was an effective way to convey the importance of creating and tolerating internal space in myself and begin to create internal space in the patient. Previously such space had been closed down in order to manage primitive fears of annihilation. When a patient is absorbed in an entangling autistic retreat words do not reach the patient on a symbolic level but rather are experienced primarily as an assault on the need for dual unity with the analyst. The patient's need to be wrapped in a sensation based world of dual unity is preferable to a world of spoken words that carry the danger of delineating psychic separateness. In essence there is no self to speak words, only a whirl of an amorphous sensation self lacking definition. I believe with certain kinds of patients it may be necessary to first lose and then work to regain one's analytic mind, as I have powerfully described in the case of Linda. Linda's profound loss of connection to

    1992-11-01

    Proton and heavy-ion radiation therapy has been taking place now for 40 years, at many accelerator laboratories around the world, essentially all of these centers built originally for physics research. The high degree of promise shown for using these particles for treating and curing cancer has stimulated the medical community to look seriously at building dedicated accelerator facilities in a hospital setting, where more rapid progress can be made in clinical research, and development of effective treatments with these beams. In the United States, the first such facility, at the Loma Linda University Medical Center, has been in operation now for two years, and is currently treating a total of 35 to 40 patients per day. Two new projects are being designed at present, one at the Massachusetts General Hospital in Boston, Massachusetts, the second a joint project of the Lawrence Berkeley Laboratory and the University of California at Davis Medical Center in Sacramento, California. This paper will discuss accelerator and beam characteristics relevant to the proton-therapy application, and will present performance and operations characteristics for the Loma Linda facility, as well as details of the plans, process and progress towards construction of the new facilities in Boston and Sacramento.

    Social media sites have become an established means of communication due to the exponential growth in number of users across the world and the encouragement of interaction between users through site features. The purpose of this study was to determine the extent to which Loma Linda University School of Dentistry students use social media accounts, the types of accounts they prefer, their interest in incorporating social media into courses and their perceptions of the usefulness of social media in private practice. In addition, we wanted to determine the degree of student interest in the integration of these social tools into their instruction. One thousand one hundred and sixty-two students from Loma Linda University School of Dentistry were invited by e-mail to complete a confidential 18 item multiple choice survey through Surveymonkey.com. The overall response rate was 30% (n = 351) from the pooled response periods; the first in 2011 and the second in 2013. Similar to other studies, Facebook was used by 91% of the School of Dentistry students, and less than half used Google+, Twitter and LinkedIn. Of the respondents, 68% of students reported communicating on social media daily and 80% saw value for practising dentists to operate accounts. Time and privacy concerns were the largest barriers to usage at 16% and 12% respectively. One third of respondents were in favour of the incorporation of social media in their courses. PMID:25377826

    A December 2010 meeting, “Down Syndrome: National Conference on Patient Registries, Research Databases, and Biobanks,” was jointly sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) at the National Institutes of Health (NIH) in Bethesda, MD, and the Global Down Syndrome Foundation (GDSF)/Linda Crnic Institute for Down Syndrome based in Denver, CO. Approximately 70 attendees and organizers from various advocacy groups, federal agencies (Centers for Disease Control and Prevention, and various NIH Institutes, Centers, and Offices), members of industry, clinicians, and researchers from various academic institutions were greeted by Drs. Yvonne Maddox, Deputy Director of NICHD, and Edward McCabe, Executive Director of the Linda Crnic Institute for Down Syndrome. They charged the participants to focus on the separate issues of contact registries, research databases, and biobanks through both podium presentations and breakout session discussions. Among the breakout groups for each of the major sessions, participants were asked to generate responses to questions posed by the organizers concerning these three research resources as they related to Down syndrome and then to report back to the group at large with a summary of their discussions. This report represents a synthesis of the discussions and suggested approaches formulated by the group as a whole. PMID:21835664

    This article presents an overview of the proceedings from a symposium entitled "Is adolescence special? Possible age-related vulnerabilities to chronic alcohol or nicotine exposure," organized by Susan Barron and Linda Spear and held at the 2004 Research Society on Alcoholism Meeting in Vancouver, British Columbia. This symposium, co-sponsored by the Fetal Alcohol Syndrome Study Group and the Neurobehavioral Teratology Society, focused on our current knowledge regarding the long-term consequences of ethanol and/or nicotine exposure during adolescence with the emphasis on data from rodent models. The support from these two societies represents the understanding by these research groups that adolescence represents a unique developmental stage for the effects of chronic drug exposure and also marks an age in which many risky behaviors including alcohol consumption and smoking typically begin. The speakers included (1) Aaron White, who presented data on the effects of adolescent ethanol exposure on subsequent motor or cognitive response to an ethanol challenge in adulthood; (2) Richard Bell, who presented data suggesting that genetic differences could play a role in adolescent vulnerability to ethanol; (3) Craig Slawecki, who presented data looking at the effects of chronic exposure to alcohol or nicotine on neurophysiologic and behavioral end points; and (4) Ed Levin, who presented data on acute and long-term consequences of adolescent nicotine exposure. Finally, Linda Spear provided some summary points and recommendations regarding unresolved issues and future directions.

    The Upper Arkansas River basin has experienced notable large floods, including the event of 2-6 June 1921 that devastated the city of Pueblo, Colorado. We investigated flood and paleoflood hydrology at strategic sites to determine the frequency and geographic extent of extreme floods within the basin for a dam safety application. Streamgage, historical, and paleoflood data were utilized to develop frequency curves at sites near Salida, Cotopaxi, Parkdale, and Pueblo. Soil/stratigraphic descriptions, radiocarbon dating, and hydraulic modeling were used to estimate paleoflood nonexceedance bounds at the four sites, which ranged from 400 to 2200 YBP for late Holocene surfaces to late Pleistocene surfaces near Cotopaxi. Peak-flow data are from lower-magnitude snowmelt runoff in May and June in the upper basin and from high-magnitude rainfall runoff from June to August in the lower basin. Flood frequency curves reflect this transition near Parkdale from snowmelt to extreme rainfall-runoff. For similar return periods, paleoflood peak discharges increase from about 480 m 3/s upstream at Loma Linda to about 4250 m 3/s downstream near Pueblo. This increase is attributed to the larger rainfall component derived from lower elevations between Loma Linda and Pueblo. Return periods for design floods at Pueblo Dam exceeded 10,000 years based on paleoflood frequency curve extrapolations.

    In spite of abundant archeological material available in Mexico, archeomagnetic studies are extremely scarce. In this work, we conducted systematic archeointensity measurements on some well-known archeological sites in central and eastern Mexico (e.g., Teotihuacan, Templo Mayor among others) to contribute to the relative and absolute chronology of Mesoamerica. Our sampling strategy was guided largely by Linda Manzanilla's detailed study of two of the most important archeological sites in Central Mexico, Teotihuacan, and Templo Mayor, since we sampled only materials that are already studied and provide more or less coherent archeological ages. Moreover, we incorporated data from some Mexican lava flows that erupted during historic times in order to extend the archeointensity master curve for Mexico and Mesoamerica to the present.

    This epidemiological study compares the frequency of resistant bacteria in stool microflora among vegetarians and nonvegetarians over a 12 month period. Two well characterized vegetarian populations (one in Boston, MA and the other in Loma Linda, CA) as well as appropriate controls were studied. No apparent differences in the prevalence of antibiotic resistance in the microflora were noted; however, vegetarians had a significantly greater incidence of multi-antibiotic resistance. E. coli of the same API biotype had the same frequency of antibiotic resistance in both vegetarians and nonvegetarians. Quantitative studies showed similar percents of tetracycline resistant facultative isolates and of "bacteroides." Klebsiella were more common in the stool of the nonvegetarians. As shown in previous studies, exposure to animal products either as meat eaters or production workers in a poultry abattoir was not associated with an increased incidence of resistant bacterial flora or infections caused by resistant strains.

    The guanine nucleotide protein (G protein)-coupled receptors (GPCRs) superfamily represents the largest class of membrane protein in the human genome. More than a half of all GPCRs are dedicated to interact with odorants and are termed odorant-receptors (ORs). Linda Buck and Richard Axel, the Nobel Prize laureates in physiology or medicine in 2004, first cloned and characterized the gene family that encode ORs, establishing the foundations to the understanding of the molecular basis for odor recognition. In the last decades, a lot of progress has been done to unravel the functioning of the sense of smell. This chapter gives a general overview of the topic of olfactory receptor signaling and reviews recent advances in this field. PMID:26928542

  9. "Old people are useless": representations of aging on the Simpsons.

    2008-01-01

    This article looks at how The Simpsons ' representations of aging, considered ageist and stereotypical by some, can be viewed as a positive look at the elderly that attempts to subvert the same stereotypes that it seemingly employs. The Baby Boom cohort is now seen as an attractive economic group, and as they continue their journey through the life cycle, they are drawing increased attention. A current scholarship exists that investigates the ways that the "aged" are seen, catered to, advertised at, seemingly marginalized, and represented in the larger context of the mass media. Relying primarily on the theoretical musings of Frederic Jameson and Linda Hutcheon, the article constructs a bridge that places The Simpsons squarely within a postmodern aesthetic and, using this rubric, shows how the inherent political nature of parodic irony can help to create an inversion of meaning.

    In the United States, estimates indicate there are between 250,000 and 400,000 individuals with Down syndrome (DS), and nearly all will develop Alzheimer's disease (AD) pathology starting in their 30s. With the current lifespan being 55 to 60 years, approximately 70% will develop dementia, and if their life expectancy continues to increase, the number of individuals developing AD will concomitantly increase. Pathogenic and mechanistic links between DS and Alzheimer's prompted the Alzheimer's Association to partner with the Linda Crnic Institute for Down Syndrome and the Global Down Syndrome Foundation at a workshop of AD and DS experts to discuss similarities and differences, challenges, and future directions for this field. The workshop articulated a set of research priorities: (1) target identification and drug development, (2) clinical and pathological staging, (3) cognitive assessment and clinical trials, and (4) partnerships and collaborations with the ultimate goal to deliver effective disease-modifying treatments.

    Measurements using silicon detectors to characterize theradiation transmitted through the EMU spacesuit and a human phantom havebeen performed using 155 and 250 MeV proton beams at the Loma LindaUniversity Medical Center (LLUMC). The beams simulate radiationencountered in space, where trapped protons having kinetic energies onthe order of 100 MeV are copious. Protons with 100 MeV kinetic energy andabove can penetrate many centimeters of water of other light materials,so that astronauts exposed to such energetic particles will receive dosesto their internal organs. This dose can be enhanced or reduced byshielding - either from the spacesuit or the self-shielding of the body -but minimization of the risk depends on details of the incident particleflux (in particular the energy spectrum) and on the dose responses of thevarious critical organs.

    Thomas is 13 years old. His parents report a sharp decline in his school grades caused, according to his teachers' opinions, by listlessness and lack of concentration. The parents of Julia, 16 years old, describe her as restless, evasive, isolated, and withdrawn from others and from her usual activities. Linda, 18 years old, is described by her parents as indecisive, uncertain, and almost lethargic. Normally resolute and a high academic achiever, she appears locked in herself, unable to make choices. We first learned about them through the accounts of their concerned parents. Claire, 19 years old, lost weight and exercised hard enough to induce amenorrhea after her young mother underwent treatment for breast cancer, including antihormonal treatment. These four teenagers have in common a parent diagnosed with cancer, undergoing or having just completed treatment.

    Proton beams offer superior characteristics for clinical radiation therapy, including the capability to localize precisely the dose to the desired target volume. Such precision enables the radiation therapist to give higher doses to the tumor while avoiding intolerable doses to adjacent normal tissues. Locoregional control is thus increased, and treatment morbidity and side effects are decreased. When it opens in late spring 1990, Loma Linda University Medical Center's proton treatment facility will feature the world's first accelerator and proton therapy system designed for patient care. During the next decade, other similarly-designed proton therapy systems will be built in Canada, England, France, Belgium, Germany, Japan, and South Africa, as well as at Massachusetts General Hospital in the United States.

Organizers Linda Hicke and Cecile Pickart put together an excellent programme of talks covering functions of ubiquitin other than its well known role in proteasomal targeting. The increasingly diverse biological processes in which the ubiquitin-like proteins (UBLs) are involved, also featured. One of the aims of the meeting was to bring together researchers working directly with ubiquitin and UBLs, and also those who have found that their favourite molecule or process is somehow influenced by these small versatile tags. As a result, delegates were treated to a diverse and highly stimulating meeting. PMID:12495835

    Traditional herbal cures and remedies have played an important historical role in the treatment of a variety of illnesses and diseases in Northern Ireland for the last three hundred years. Recently, these have been reviewed in the publication by Linda Ballard from the Ulster Folk and Transport Museum at Cultra, Co. Down, which details the variety of local plants used and for what purpose. From this publication and another related publication, we note the description of several plant species that consistently appear in traditional cures and remedies, particularly used to treat infections and infectious diseases. Unfortunately, although these plants have strong associations with the local historical evidence base, there are very limited and mainly no formal publications in the medical/scientific evidence base, examining their scientific background and clinical efficacy.

    The Strategic Defense Initiative's (SDI) investment in particle accelerator technology for its directed energy weapons program has produced breakthroughs in the size and power of new accelerators. These accelerators, in turn, have produced spinoffs in several areas: the radio frequency quadrupole linear accelerator (RFQ linac) was recently incorporated into the design of a cancer therapy unit at the Loma Linda University Medical Center, an SDI-sponsored compact induction linear accelerator may replace Cobalt-60 radiation and hazardous ethylene-oxide as a method for sterilizing medical products, and other SDIO-funded accelerators may be used to produce the radioactive isotopes oxygen-15, nitrogen-13, carbon-11, and fluorine-18 for positron emission tomography (PET). Other applications of these accelerators include bomb detection, non-destructive inspection, decomposing toxic substances in contaminated ground water, and eliminating nuclear waste.

    Abstract We describe three new, allopatric species of springsnails (genus Pyrgulopsis) from western California (Pyrgulopsis lindae, Pyrgulopsis ojaiensis, Pyrgulopsis torrida) that were previously identified as Pyrgulopsis stearnsiana. The new species are differentiated from Pyrgulopsis stearnsiana and each other both by mtCOI sequences (3.9-9.9%) and details of penial morphology. We also provide a phylogeny with increased sampling which confirms a previous finding that Pyrgulopsis stearnsiana sensu stricto is paraphyletic relative to two other California species (Pyrgulopsis diablensis, Pyrgulopsis giulianii). Our molecular and morphological evidence suggests that Pyrgulopsis stearnsiana paraphyly is an artifact of conservative taxonomy, however additional studies utilizing rapidly evolving genetic markers will be needed to confidently tease apart the cryptic diversity in this widely ranging springsnail. The new species described herein are narrowly distributed and vulnerable to anthropogenic stressors. The single known population of Pyrgulopsis torrida may have become extirpated between 2000 and 2015. PMID:27551184

    Radiation therapy with hadron beams now has a 40-year track record at many accelerator laboratories around the world, essentially all of these originally physics-research oriented. The great promise shown for treating cancer has led the medical community to seek dedicated accelerator facilities in a hospital setting, where more rapid progress can be made in clinical research. This paper will discuss accelerator and beam characteristics relevant to hadron therapy, particularly as applied to hospital-based facilities. A survey of currently-operating and planned hadron therapy facilities will be given, with particular emphasis on Lorna Linda (the first dedicated proton facility in a hospital) and HIMAC (the first dedicated heavy-ion medical facility).

    A leadership conference titled "Have Patient Safety and the Workforce Shortage Created the Perfect Storm?" was held in honor of Dr. Ada Sue Hinshaw, who was ending her tenure as dean of the University of Michigan School of Nursing. A morning panel on the preferred future for practice featured plenary speaker Dr. Linda Burnes Bolton and participating panelists Dr. Sanjay Saint, Dr. Jane Barnsteiner, and Dr. Joanne Disch. Each speaker presented a unique yet complementary perspective, with several common themes permeating the morning's presentations. For example, all of the speakers mentioned how important interprofessional collaboration is to promoting patient safety. The themes can be categorized broadly as nursing practice and work environment issues, with subthemes of interprofessional communication and collaboration, systems solutions to patient safety problems, and future directions in nursing education. A synopsis of comments made during the morning practice panel and empirical support for the themes and subthemes identified by panelists are provided in this article. PMID:18091296

  1. Labeling bias and categorical induction: generative aspects of category information.

    PubMed

    Yamauchi, Takashi

    2005-05-01

    When a person is characterized categorically with a label (e.g., Linda is a feminist), people tend to think that the attributes associated with that person are central and long lasting (S. Gelman & G. D. Heyman, 1999). This bias, which is related to category-based induction and stereotyping, has been thought to arise because a category label (e.g., feminist) activates the dominant properties associated with the representation of the category. This explanation implies that categorical information influences inferential processes mainly by conjuring up main attributes or instances represented in the category. However, the present experiments reveal that this attribute-based explanation of induction does not provide a complete picture of inferential processes. The results from 3 experiments suggest that category information can affect inferences of attributes that are not directly related to the category, suggesting that categories not only activate likely attributes but also help integrate unlikely or even unrelated attributes.

    Chemical geothermometry surveys of well waters in the Arrowhead Hot Springs, Bunker Hill Basin, and other basins located near San Bernardino, CA suggest temperatures up to 140C for waters ascending along fault zones. Calculated temperatures from geothermometry are nearly always higher than the measured temperatures of 87C at Arrowhead Hot Springs and 63C in a well sited on the Loma Linda Fault. Mixing of the geothermal waters with shallow, dilute groundwaters is indicated by ternary molality plots of C1, B, and HCO3 and C1, F, and HCO3. The source of the geothermal component appears to be deep circulation in fractured crystalline basement complex. Circulation at depth is enhanced and directed along the major strikeslip fault zones of the region.

    In 2005 John Licciardone, Angela Brimhall, and Linda King published a systematic review and meta-analysis of randomized controlled trials with the title: Osteopathic manipulative treatment for low back pain. The conclusions of systematic review and meta-analysis depend highly on the right search strategy, the quality of the included studies (internal validity), and the error-free, unbiased and transparent evaluation of the review. As illustrated by the following article Licciardone's review includes elements that could lead to biased results. It is concluded that Licciardone et al. focused too much on the statistical significance, and overlooked that the problem of the review lay not in the calculations but in the quality and compilation of the studies.

    A tuple space based object oriented model for knowledge base representation and interpretation is presented. An architecture for managing distributed knowledge agents is then implemented within the model. The general model is based upon a database implementation of a tuple space. Objects are then defined as an additional layer upon the database. The tuple space may or may not be distributed depending upon the database implementation. A language for representing knowledge and inference strategy is defined whose implementation takes advantage of the tuple space. The general model may then be instantiated in many different forms, each of which may be a distinct knowledge agent. Knowledge agents may communicate using tuple space mechanisms as in the LINDA model as well as using more well known message passing mechanisms. An implementation of the model is presented describing strategies used to keep inference tractable without giving up expressivity. An example applied to a power management and distribution network for Space Station Freedom is given.

  7. Comparisons between GRNTRN simulations and beam measurements of proton lateral broadening distributions

    Recent developments in NASA's High Charge and Energy Transport (HZETRN) code have included lateral broadening of primary ion beams due to small-angle multiple Coulomb scattering, and coupling of the ion-nuclear scattering interactions with energy loss and straggling. The new version of HZETRN based on Green function methods, GRNTRN, is suitable for modeling transport with both space environment and laboratory boundary conditions. Multiple scattering processes are a necessary extension to GRNTRN in order to accurately model ion beam experiments, to simulate the physical and biological-effective radiation dose, and to develop new methods and strategies for light ion radiation therapy. In this paper we compare GRNTRN simulations of proton lateral scattering distributions with beam measurements taken at Loma Linda Medical University. The simulated and measured lateral proton distributions will be compared for a 250 MeV proton beam on aluminum, polyethylene, polystyrene, bone, iron, and lead target materials.

    This article applies the rhetorical and deliberately provocative approach of the watershed essay art historian Linda Nochlin wrote in 1971—“Why Have there Been No Great Women Artists?”—to today's culinary industry. Nochlin used the question her title posed as a theoretical trap that would draw attention not only to the inherent sexism or prejudice that pervades the way the public perceives art, but also to those same issues' existence within and impact on academia and the other cultural institutions responsible for posing these sorts of questions. Nochlin bypassed the obvious and irrelevant debate over women's being less or differently talented and, in so doing, exposed that debate for being a distraction from the heart of the matter: how, sociologically (media) or institutionally (museums, foundations, etc.), people define a “great artist.” Although it's 40 years later, the polemic is as effective when used to understand the gender divide in the food world.

    Background In 2010, the Department of Veterans Affairs (VA) implemented a national patient-centered care initiative that organized primary care into interdisciplinary teams of health care professionals to provide patient-centered, continuous, and coordinated care. Objective We assessed the discriminate validity of the Learners' Perceptions Survey—Primary Care (LPS-PC), a tool designed to measure residents' perceptions about their primary and patient-centered care experiences. Methods Between October 2010 and June 2011, the LPS-PC was administered to Loma Linda University Medical Center internal medicine residents assigned to continuity clinics at the VA Loma Linda Healthcare System (VALLHCS), a university setting, or the county hospital. Adjusted differences in satisfaction ratings across settings and over domains (patient- and family-centered care, faculty and preceptors, learning, clinical, work and physical environments, and personal experience) were computed using a generalized linear model. Results Our response rate was 86% (77 of 90). Residents were more satisfied with patient- and family-centered care at the VALLHCS than at either the university or county (P < .001). However, faculty and preceptors (odds ratio [OR]  =  1.53), physical (OR  =  1.29), and learning (OR  =  1.28) environments had more impact on overall resident satisfaction than patient- and family-centered care (OR  =  1.08). Conclusions The LPS-PC demonstrated discriminate validity to assess residents' perceptions of their patient-centered clinical training experience across outpatient primary care settings at an internal medicine residency program. The largest difference in scores was the patient- and family-centered care domain, in which residents rated the VALLHCS much higher than the university or county sites. PMID:24455006

Armenta, Richard M. Lee, Adriana J. Umaña-Taylor, Seth J. Schwartz, Ian K. Villalta, Byron L. Zamboanga, Robert S. Weisskirch, Linda P. Juang, Linda G. Castillo and Monika L.

(The following abstract of the original article appeared in record 2014-31330-001.) Ethnic group discrimination represents a notable risk factor that may contribute to mental health problems among ethnic minority college students. However, cultural resources (e.g., ethnic identity) may promote psychological adjustment in the context of group-based discriminatory experiences. In the current study, we examined the associations between perceptions of ethnic group discrimination and depressive symptoms, and explored dimensions of ethnic identity (i.e., exploration, resolution, and affirmation) as mediators of this process among 2,315 ethnic minority college students (age 18 to 30 years; 37% Black, 63% Latino). Results indicated that perceived ethnic group discrimination was associated positively with depressive symptoms among students from both ethnic groups. The relationship between perceived ethnic group discrimination and depressive symptoms was mediated by ethnic identity affirmation for Latino students, but not for Black students. Ethnic identity resolution was negatively and indirectly associated with depressive symptoms through ethnic identity affirmation for both Black and Latino students. Implications for promoting ethnic minority college students' mental health and directions for future research are discussed. PMID:26168165

    In neurocognitive research on language, the processing principles of the system at hand are usually assumed to be relatively invariant. However, research on attention, memory, decision-making, and social judgment has shown that mood can substantially modulate how the brain processes information. For example, in a bad mood, people typically have a narrower focus of attention and rely less on heuristics. In the face of such pervasive mood effects elsewhere in the brain, it seems unlikely that language processing would remain untouched. In an EEG experiment, we manipulated the mood of participants just before they read texts that confirmed or disconfirmed verb-based expectations about who would be talked about next (e.g., that “David praised Linda because … ” would continue about Linda, not David), or that respected or violated a syntactic agreement rule (e.g., “The boys turns”). ERPs showed that mood had little effect on syntactic parsing, but did substantially affect referential anticipation: whereas readers anticipated information about a specific person when they were in a good mood, a bad mood completely abolished such anticipation. A behavioral follow-up experiment suggested that a bad mood did not interfere with verb-based expectations per se, but prevented readers from using that information rapidly enough to predict upcoming reference on the fly, as the sentence unfolds. In all, our results reveal that background mood, a rather unobtrusive affective state, selectively changes a crucial aspect of real-time language processing. This observation fits well with other observed interactions between language processing and affect (emotions, preferences, attitudes, mood), and more generally testifies to the importance of studying “cold” cognitive functions in relation to “hot” aspects of the brain.

    In neurocognitive research on language, the processing principles of the system at hand are usually assumed to be relatively invariant. However, research on attention, memory, decision-making, and social judgment has shown that mood can substantially modulate how the brain processes information. For example, in a bad mood, people typically have a narrower focus of attention and rely less on heuristics. In the face of such pervasive mood effects elsewhere in the brain, it seems unlikely that language processing would remain untouched. In an EEG experiment, we manipulated the mood of participants just before they read texts that confirmed or disconfirmed verb-based expectations about who would be talked about next (e.g., that "David praised Linda because … " would continue about Linda, not David), or that respected or violated a syntactic agreement rule (e.g., "The boys turns"). ERPs showed that mood had little effect on syntactic parsing, but did substantially affect referential anticipation: whereas readers anticipated information about a specific person when they were in a good mood, a bad mood completely abolished such anticipation. A behavioral follow-up experiment suggested that a bad mood did not interfere with verb-based expectations per se, but prevented readers from using that information rapidly enough to predict upcoming reference on the fly, as the sentence unfolds. In all, our results reveal that background mood, a rather unobtrusive affective state, selectively changes a crucial aspect of real-time language processing. This observation fits well with other observed interactions between language processing and affect (emotions, preferences, attitudes, mood), and more generally testifies to the importance of studying "cold" cognitive functions in relation to "hot" aspects of the brain.

    Hathaway, David H.

    2005-12-01

    Jason Porter, a solar astronomer at NASA's Marshall Space Flight Center (MSFC), died on 23 July 2005 from complications associated with his 18-year battle with a form of non-Hodgkin's lymphoma. He was born on 28 June 1954. Jason was Texas born and bred. He received his Bachelor's degree from Texas A&M in 1976 and then went to the University of Colorado for his graduate work. He received his PhD from the Department of Astrophysical, Planetary, and Atmospheric Sciences in 1984. His thesis, "Ultraviolet Spectral Diagnostics of Solar Flares and Heating Events," was written under the guidance of Katharine Gebbie and Juri Toomre. The ideas behind his thesis and much of his later work were formulated while he was a Graduate Research Assistant at Goddard Space Flight Center (GSFC) working on analysis of data from the Ultraviolet Spectrometer and Polarimeter, a major instrument on the Solar Maximum Mission (SMM). While at Goddard, he met his wife-to-be, Linda Zimmerman, who was working as a computer system administrator at the SMM Operations Center. They married and moved to Huntsville, Alabama in 1984 where Jason had an appointment as an NAS/NRC Resident Research Associate in the Solar Physics Branch of MSFC and Linda was a system administrator for the Space Science Laboratory. After a short stint at the University of Alabama in Huntsville, Jason joined NASA as a Senior Scientist in the Space Science Laboratory in 1987, a position he still held at the time of his death. Jason's early work brought forth the idea that "microflares" make a significant contribution to the heating of the solar corona, an idea which he continued to champion throughout his career. He also searched for coronal emission from white dwarf stars using the ROSAT and Chandra Space Observatories, and served as the NASA Project Scientist for a lunar based ultraviolet telescope. More recently he was leading a team of engineers and scientists, from MSFC, GSFC, and the National Solar Observatory on the

  16. Quantum Poetics: Science and Spirit in Twentieth Century American Poetry

    NASA Astrophysics Data System (ADS)

    Monaghan, (Mary) Patricia

    Concepts from quantum physics illuminate ways in which five 20th century American poets struggle with the expression of nonlinear, nontemporal experiences in linear, temporal language. An "experience of spirit"- -an experience of cosmic unity which occurs in a timeless moment and involves a paradoxical sensuality--is expressed by poets Wallace Stevens, Albert Goldbarth, Nancy Willard, Linda Gregg and Marilyn Waniek. Contemporary science similarly seeks ways to express nonlinear realities in linear language. The English language is found to guide users to linear, time-bounded expression through the noun (leading to nominalization), the verb (demanding experience be limited to past, present or future), adverb and adjective (which separate senses from each other and divide attributes from essence). English presents structural difficulties to those who wish to express experiences of spirit--difficulties also articulated by quantum theorists struggling to express unvisualizable concepts. Wallace Stevens devoted the first half of his poetic career to questions of order, which find reflections within the works of quantum physicists who theorize an "implicate order" within the subatomic universe. During his later years, Stevens turned to the question of chaos, an interest paralleled by recent developments in dynamical systems theory. Albert Goldbarth and Nancy Willard alter narrative form in three ways to convey nonlinear possibilities. The "parabolic" narrative uses story to exemplify a moral or philosophical message. The "midrashic" illuminates the meaning of one story by the telling of another. Finally, the "coyotic" begins with one, apparently ordinary, story which is then altered to introduce fantastical realities. These narratives form a "relative time," similar to that which Einstein defined in his special theory of relativity. The works of Marilyn Waniek and Linda Gregg are examined in terms of the language of paradoxical sensuality, which calls into question the

  17. Status and perspectives of the studies on anomalous phosphene perceptions in the frame of the ALTEA program

    One of the major aims of the ALTEA program is to study the anomalous phosphenes per-ceptions reported by astronauts since Apollo 11 lunar flight. This is pursued via space and ground-based experiments. The ALTEA detection systems in the ISS allow concurrent mea-surement of the particles travelling through the brain/eyes of the astronauts (discriminating Z and trajectory of the ions), as well as the electrophysiological brain activity, including the retinogram, and the instances of phosphene perceptions. These measurements permitted to document the electrophysiological responses to particle passages concomitant with phosphene perception with links between the electrophysiological signals and ions traveling through the eye. We have also measured the average number of ions impinging in the eye / brain of the astronaut per minute. On ground-based experiments we have measured the mouse electrophys-iological responses to very short (¡ 5 ms) 12C bursts in the eyes, and the summation effect of the 12C/light stimuli concomitance. We also studied hadron therapy patients reporting phosphenes when irradiated. At the carbon-ion treatment unit at GSI (Darmstadt, Germany) we also em-ployed electrophysiological recording, while at the proton therapy center in Orsay, France and at Loma Linda (CA, USA) we are collecting subjective data from treated patients. In the GSI case we have been able to measure electrophysiological responses to ion bursts and to link the perceptions to specific irradiated regions. At Loma Linda the perceived phosphenes correlate temporally with individual accelerator spills, so that the patients can count them. They appear bright white or intense cobalt blue (essentially no other colors) depending on the portion of the eye/optic nerve receiving dose. Foul or burning smells and taste illusions that may last from days to more than a week were also reported during irradiation. In Orsay patients routinely perceive flashes, mostly light blue, but also white

    We report on the operation and performance tests of a preclinical head scanner developed for proton computed tomography (pCT). After extensive preclinical testing, pCT is intended to be employed in support of proton therapy treatment planning and pre-treatment verification in patients undergoing particle-beam therapy. In order to assess the performance of the scanner, we have performed CT scans with 200 MeV protons from both the synchrotron of the Loma Linda University Medical Center (LLUMC) and the cyclotron of the Northwestern Medicine Chicago Proton Center (NMCPC). The very high sustained rate of data acquisition, exceeding one million protons per second, allowed a full 360° scan to be completed in less than 7 min. The reconstruction of various phantoms verified accurate reconstruction of the proton relative stopping power (RSP) and the spatial resolution in a variety of materials. The dose for an image with better than 1% uncertainty in the RSP is found to be close to 1 mGy.

    An ion-counting nanodosemeter (ND) yielding the distribution of radiation-induced ions in a low-pressure gas within a millimetric, wall-less sensitive volume (SV) was equipped with a silicon microstrip telescope that tracks the primary particles, allowing correlation of nanodosimetric data with particle position relative to the SV. The performance of this tracking ND was tested with a broad 250 MeV proton beam at Loma Linda University Medical Center. The high-resolution tracking capability made it possible to map the ion registration efficiency distribution within the SV, for which only calculated data were available before. It was shown that tracking information combined with nanodosimetric data can map the ionisation pattern of track segments within 150 nm-equivalent long SVs with a longitudinal resolution of approximately 5 tissue-equivalent nanometers. Data acquired in this work were compared with results of Monte Carlo track structure simulations. The good agreement between 'tracking nanodosimetry' data acquired with the new system and simulated data supports the application of ion-counting nanodosimetry in experimental track-structure studies.

    Renewed interest by several major university medical centers (UCSF, Stanford, U. of Washington, Loma Linda) in conducting Boron Neutron Capture Therapy (BNCT) led to the investigation of generating a continuous proton beam with 2.5 MeV of energy and up to 100 mA of current. The power supply for the Heavy Ion Injector (Adam) at LBNL operated at lower currents from its completion in 1970 until it was shut down in 1993. This power supply consisted of 64 stages of shunt-fed multipliers (Dynamitron) and seemed to offer an attractive first step for BNCT experiments. The Adam power supply was reactivated in June of 1995 and extensive tests were performed to establish its maximum capability. After the tests were completed, it became clear that 100 mA was well beyond the capability of this power source and that even 10-20 mA would require extensive modifications. After some initial conceptual design studies, it was decided that the air-coupled transformer with multiple secondaries warranted some serious investigations and could offer the best chance for achieving 100 mA.

  1. Is experiential-intuitive cognitive style more inclined to err on conjunction fallacy than analytical-rational cognitive style?

    In terms of prediction by Epstein’s integrative theory of personality, cognitive-experiential self-theory (CEST), those people with experiential-intuitive cognitive style are more inclined to induce errors than the other people with analytical-rational cognitive style in the conjunction fallacy (two events that can occur together are seen as more likely than at least one of the two events). We tested this prediction in a revised Linda problem. The results revealed that rational and experiential cognitive styles do not statistically influence the propensity for committing the conjunction fallacy, which is contrary to the CEST’s predictions. Based on the assumption that the rational vs. experiential processing is a personality trait with comparatively stabile specialities, these findings preliminarily indicate that those people who are characterized by “rational thinking” are not more inclined to use Bayes’ deduction than the other people who are labeled by “intuitive thinking” or by “poor thinking.” PMID:25705198

  2. A Wave-Based Approach for Seismic Response Analyses of High-Rise Buildings

    Zhang, R.; Hilali, S. Al; Abdulla, A.; Kurbi, M. Al

    This study examines one-dimensional wave propagation in a multi-story building with seismic excitation. In particular, the building is modeled as a series of shear beams for columns/walls and lumped masses for floors. Wave response at one location of the building is then derived to an impulse displacement at another location in time and frequency domains, termed here as wave-based or generalized impulse/frequency response function (GIRF/GFRF), which is dependent upon the building characteristics above the impulse location. Not only does this study illustrate features of GIRF/GFRF in terms of building properties, it also shows broad-based applications of the modeling. Two examples are presented with the use of the modeling. One is wave-based characterization of ten-story Millikan Library in Pasadena, California with the recordings of Yorba Linda earthquake of September 3, 2002. The other is analysis for influence of stochastic floor-to-column mass ratio, story-height and seismic input in seismic wave responses.

    The International Workshop on the Molecular Biology of the Stress Response organized by the Cell Stress Society International was held in Porto Alegre, Brazil, on May 27-30, 2012, as part of the development of the Latin American Chapter of the Society, a superb initiative headed by Drs. Antonio De Maio and Larry Hightower. The meeting took place in the wonderful facilities of the Pontifícia Universidade do Rio Grande do Sul (PUCRS) and was warmly chaired by Professor Cristina Bonorino. Thirty-four invited speakers presented their work to more than 200 scientists and, even more importantly, to 150 registered students, who were the main beneficiaries of the meeting. The first day of the workshop was dedicated to an educational program for students, young investigators, and participants who were unfamiliar with the field of molecular chaperones and the stress response. Speakers in this pre-workshop were Dr. Harm Kampinga, Dr. Lea Sistonen, Dr. Larry Hightower, Dr. Ivor Benjamin, Dr. Daniel Ciocca, and Dr. Linda Hendershot.

    The objective of this study was to determine the effectiveness of localized laser pulp surgery in the canine model. Effects of laser parameters on treatment outcome were also investigated. Pulpal exposure 3 mm in diameter were prepared in healthy teeth and left open to infection from the oral cavity for 72 hours. Pulpal tissue was then removed using high speed handpiece with sterile irrigation, or a CO2 laser. Teeth were monitored clinically, radiographically for 3 months. Results for each criterion were evaluated on a scale of 0-(-2). After sacrifice, histological assessment was made soft and hard tissue response. Results for each category were evaluated on a standard scale of 0-(-2). All evaluations were performed by 1 blinded, pre-standardized clinician. Statistical assessment using the chi-square test and Fisher's Exact Test associated laser treatment with a significantly better clinical, radiographic and histological treatment outcome.

    Measures used in the selection of international dental students to a U.S. D.D.S. program were examined to identify the grouping that most effectively and efficiently predicted academic performance and clinical competency. Archival records from the International Dental Program (IDP) at Loma Linda University provided data on 171 students who had trained in countries outside the United States. The students sought admission to the D.D.S. degree program, successful completion of which qualified them to sit for U.S. licensure. As with most dental schools, competition is high for admission to the D.D.S. program. The study's goal was to identify what measures contributed to a fair and accurate selection process for dental school applicants from other nations. Multiple regression analyses identified National Board Part II and dexterity measures as significant predictors of academic performance and clinical competency. National Board Part I, TOEFL, and faculty interviews added no significant additional help in predicting eventual academic performance and clinical competency.

    The surrounding outdoor environment for new development has a big effect on the indoor quality of life. The main aim of this work was to determine the suitability of the area for building new schools with reference to electromagnetic field (EMF) effects. The specific objective of this study was to detect the safe distance from the EMF posed by the high-tension overhead power lines in the vicinity of the specified area. The measurements were taken for both the electric and magnetic fields in different months in order to detect the highest EMF levels during the peak power load season. EMDEX II with E-probe and EMDEX II with Linda were used for the measurements. These instruments were all calibrated by ENERTECH Company in USA. The EMF associated with high tension transmission lines that surrounded the proposed site has to be below 0.2 μT (Italian EMF regulations are the most suitable regulations for the establishment of schools in Kuwait). The safety clearance distance from the existing 300-kV high-tension power line has been assigned as 200 m and from other existing 132-kV high-tension power line was 50 m. The proposed site with its predefined boundaries has a magnetic field below the Italian EMF regulations for the establishment of new schools.

    We discuss the general state of affairs in a variety of related area ranging from software safety, reliability, and testing, protocol specification and verification, network congestion-control and reliability, to communication security and complexity. We intend to identify useful theory and tools, point out connections between different areas, and to a large extent, raise a number of questions whose answers may still lie far beyond the limits of out current knowledge. Some of these areas are still in a very primitive state and call for new ideas, bold approaches, radical thinking and perhaps extraordinary efforts. This paper is originally the overview of the report consisted of the following surveys in selected areas, two of which (A and B) also appear in this issue. A.

    Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-chromosome-linked hereditary disorder. Clinically, patients with G6PD deficiency often present with drug- or food-induced hemolytic crises or neonatal jaundice. G6PD is involved in the generation of NADPH and reduced glutathione. In contrast to American, Mediterranean, and African ancestries, only few variants are known from Middle and Northern Europe. We describe the molecular characterization of a distinct variant from the northwestern area of Germany, G6PD Aachen. The sequence of the G6PD gene from three afflicted males was found to be hemizygous at cDNA residue 1089 for a C-->G mutation with a predicted amino acid change of Asn363Lys. The 1089 C-->G point mutation is unique, but produces the identical amino acid change found in a Mexican variant of G6PD deficiency, G6PD Loma Linda. This G6PD-deficient variant is caused by a 1089 C-->A mutation. The 363-amino-acid replacement is located outside a known mutation cluster region between amino acid residues 380 and 450, but may disrupt or weaken dimer interactions of G6PD enzyme subunits.

    The project was directed toward planning, developing, and implementing a subregional biomedical information network among the forty-three health care facilities (hospitals) of the four-county area served by Loma Linda University's health sciences library. The project coordinator contacted administrators and health care professionals in the forty-three institutions to present a plan for the network. The health care facilities were encouraged to support the continuation of the network through contract fees. The availability of specific information services was assured through contractual agreements. It was anticipated that the subregional network would be self-supporting after the twelve-month project period (December 1, 1976-November 30, 1977). The working territory (40,429 square miles) encompassed Mono, Inyo, Riverside, and San Bernardino counties. The project resulted in nine of the forty-three hospitals signing annual contracts for library services. It is recommended that projects of this kind extend beyond a year's duration in order to educate health professionals concerning the value of access to biomedical literature in improving patient care.

    In previous years we demonstrated an imaging informatics system designed to support multi-institutional research focused on the utilization of proton radiation for treating spinal cord injury (SCI)-related pain. This year we will demonstrate an update on the system with new modules added to perform image processing on evaluation data using immunhistochemistry methods to observe effects of proton therapy. The overarching goal of the research is to determine the effectiveness of using the proton beam for treating SCI-related neuropathic pain as an alternative to invasive surgical lesioning. The research is a joint collaboration between three major institutes, University of Southern California (data collection/integration and image analysis), Spinal Cord Institute VA Healthcare System, Long Beach (patient subject recruitment), and Loma Linda University and Medical Center (human and preclinical animal studies). The system that we are presenting is one of its kind which is capable of integrating a large range of data types, including text data, imaging data, DICOM objects from proton therapy treatment and pathological data. For multi-institutional studies, keeping data secure and integrated is very crucial. Different kinds of data within the study workflow are generated at different stages and different groups of people who process and analyze them in order to see hidden patterns within healthcare data from a broader perspective. The uniqueness of our system relies on the fact that it is platform independent and web-based which makes it very useful in such a large-scale study.

    An Area Health Education Center (AHEC) system has been established in California to address the maldistribution of physicians and other health care professionals. The AHEC program uses educational incentives to recruit and retain health care personnel in underserved areas by linking the academic resources of university health science centers with local educational and clinical facilities. The medical schools, working in partnership with urban or rural AHECs throughout the state, are implementing educational programs to attract trainees and licensed professionals to work in underserved communities. The California AHEC project entered its fifth year in October of 1983 with the participation of all eight medical schools and the Charles Drew Postgraduate School of Medicine, 35 other health professions schools, 17 independent AHECs and more than 400 clinical training sites. Educational programs are reaching more than 22,000 students and practicing health professionals throughout California. We review the current status of the California AHEC system and use the AHEC programs at Loma Linda University to illustrate the effect this intervention is having.

    2016-08-01

    Stigma processes play an underrecognized role in the distribution of life chances, influencing health through the production of disadvantage and the induction of stress. Policies enact stigma processes, mitigate them, or ignore them. If each of these two statements is correct, the intersection of stigma and policy demands our attention. We propose a change of perspective from an approach that considers one stigmatized status and one outcome at a time to a perspective that considers the full range of stigmatized statuses and outcomes so as to reveal stigma's full impact. Concerning the second statement, literature addressing "structural stigma" provides compelling evidence that policy enacts stigma and harms health in some circumstances and mitigates stigma and improves health in others. In addition to the effects of active policies, we also bring attention to policy inattention-doing nothing. A core feature of stigma is a discounting-a mattering less-that allows and even fosters policy inattention toward the concerns of stigmatized groups. We end by engaging David Mechanic and Linda H. Aiken's ideas concerning how social science influences policy by changing how people think about problems and hope that our consideration of stigma and policy might ultimately have such a consequence.

    Recent developments in NASA’s deterministic High charge (Z) and Energy TRaNsport (HZETRN) code have included lateral broadening of primary ion beams due to small-angle multiple Coulomb scattering, and coupling of the ion-nuclear scattering interactions with energy loss and straggling. This new version of HZETRN is based on Green function methods, called GRNTRN, and is suitable for modeling transport with both space environment and laboratory boundary conditions. Multiple scattering processes are a necessary extension to GRNTRN in order to accurately model ion beam experiments, to simulate the physical and biological-effective radiation dose, and to develop new methods and strategies for light-ion radiation therapy. In this paper we compare GRNTRN simulations of proton lateral broadening distributions with beam measurements taken at Loma Linda University Proton Therapy Facility. The simulated and measured lateral broadening distributions are compared for a 250 MeV proton beam on aluminum, polyethylene, polystyrene, bone substitute, iron, and lead target materials. The GRNTRN results are also compared to simulations from the Monte Carlo MCNPX code for the same projectile-target combinations described above.

    Much remains unknown about the genetic status and population connectivity of high-elevation and high-latitude freshwater invertebrates, which often persist near snow and ice masses that are disappearing due to climate change. Here we report on the conservation genetics of the meltwater stonefly Lednia tumana (Ricker) of Montana, USA, a cold-water obligate species. We sequenced 1530 bp of mtDNA from 116 L. tumana individuals representing “historic” (>10 yr old) and 2010 populations. The dominant haplotype was common in both time periods, while the second-most-common haplotype was found only in historic samples, having been lost in the interim. The 2010 populations also showed reduced gene and nucleotide diversity and increased genetic isolation. We found lower genetic diversity in L. tumana compared to two other North American stonefly species, Amphinemura linda (Ricker) and Pteronarcys californica Newport. Our results imply small effective sizes, increased fragmentation, limited gene flow, and loss of genetic variation among contemporary L. tumana populations, which can lead to reduced adaptive capacity and increased extinction risk. This study reinforces concerns that ongoing glacier loss threatens the persistence of L. tumana, and provides baseline data and analysis of how future environmental change could impact populations of similar organisms.

Methods and Materials: Between 1991 and 2002, 72 patients were treated at Loma Linda University Medical Center with proton therapy for cavernous sinus meningiomas. Fifty-one patients had biopsy or subtotal resection; 47 had World Health Organization grade 1 pathology. Twenty-one patients had no histologic verification. Twenty-two patients received primary proton therapy; 30 had 1 previous surgery; 20 had more than 1 surgery. The mean gross tumor volume was 27.6 cm{sup 3}; mean clinical target volume was 52.9 cm{sup 3}. Median total doses for patients with and without histologic verification were 59 and 57 Gy, respectively. Mean and median follow-up periods were 74 months. Results: The overall 5-year actuarial control rate was 96%; the control rate was 99% in patients with grade 1 or absent histologic findings and 50% for those with atypical histology. All 21 patients who did not have histologic verification and 46 of 47 patients with histologic confirmation of grade 1 tumor demonstrated disease control at 5 years. Control rates for patients without previous surgery, 1 surgery, and 2 or more surgeries were 95%, 96%, and 95%, respectively. Conclusions: Fractionated proton radiotherapy for grade 1 cavernous sinus meningiomas achieves excellent control rates with minimal toxicities, regardless of surgical intervention or use of histologic diagnosis. Disease control for large lesions can be achieved by primary fractionated proton therapy.

    Although the space radiation environment consists predominantly of energetic protons, astronauts inside a spacecraft are chronically exposed to both primary particles as well as secondary particles that are generated when the primary particles penetrate the spacecraft shielding. Secondary neutrons and secondary charged particles can have an LET value that is greater than the primary protons and, therefore, produce a higher relative biological effectiveness (RBE). Using the accelerator facility at Loma Linda University, we exposed human lymphocytes in vitro to 250 MeV protons with doses ranging from 0 to 60 cGy at three different dose rates: a low dose rate of 7.5 cGy/h, an intermediate dose rate of 30 cGy/h and a high dose rate of 70 cGy/min. The effect of 15 g/cm2 aluminum shielding on the induction of chromosome aberrations was investigated for each dose rate. After exposure, lymphocytes were incubated in growth medium containing phytohemagglutinin (PHA) and chromosome spreads were collected using a chemical-induced premature chromosome condensation (PCC) technique. Aberrations were analyzed using the fluorescence in situ hybridization (FISH) technique with three different colored chromosome-painting probes. The frequency of reciprocal and complex-type chromosome exchanges were compared in shielded and unshielded samples. c2002 COSPAR. Published by Elsevier Science Ltd. All rights reserved.

    Response of thermoluminescent detectors (TLD-100) to high linear energy transfer (LET) particles has been studied using helium, carbon, silicon, and iron ions from the Heavy Ion Medical Accelerator at Chiba (Japan), iron ions from the Brookhaven National Laboratory (NY) Alternate Gradient Synchrotron, and 53, 134, 185, and 232 MeV protons from the Loma Linda accelerator. Using the measured relative (to (137)Cs dose efficiency, and measured LET spectra from a tissue equivalent proportional counter (TEPC) on 20 Space Shuttle flights, and 7 Mir flights, the underestimation of absorbed dose by these detectors has been evaluated. The dose underestimation is between 15-20% depending upon the flight inclination and shielding location. This has been confirmed by direct correlation of measured dose by TEPC and TLD-100 at a low shielded location in the Shuttle mid-deck. A comparison of efficiency- LET data with a compilation of similar data from TLD-700, shows that shapes of the two curves are nearly identical, but that the TLD-100 curve is systematically lower by about 13%, and is the major cause of dose underestimation. These results strongly suggest that TLDs used for crew dose estimation be regularly calibrated using heavy ions.

    This qualitative study delineates motives for residential mobility, describes dynamics between the elder and family members during the move decision process, and locates the move decision within ecological layers of the aging context. Interviews were conducted with 30 individuals and couples (ages 60-87) who experienced a community-based move within the past year, and with 14 extended family members. Reasons for moving (from perspectives of both elders who moved and their family members) were grouped into four themes and eleven issues that influenced the move decision. These themes parallel the ecological context of individual health and functioning, beliefs and attitudes, physical environment, and social pressures. Late-life mobility is a significant life transition that is the outcome of an ongoing appraisal and reappraisal of housing fit with individual functioning, needs, and aspirations. Family members are an integral part of these decision and residential mobility processes. Well, she moved because my sister and I decided she was going to move. But she wanted to move. It wouldn’t have happened if we hadn’t decided that she was gonna move. It was a little complicated . . . - Linda Brierton’s daughter, Karen PMID:18453180

    This theoretical paper introduces the concept of the "negotiated space", a model developed by Linda Tuhiwai Smith, Maui Hudson and colleagues describing the interface between different worldviews and knowledge systems. This is primarily a conceptual space of intersection in-between different ways of knowing and meaning making, such as, the i Pacific indigenous reference and the dominant Western mental health paradigm of the bio-psycho-social. When developing Pacific models of care, the "negotiated space" provides room to explore the relationship between different (and often conflicting) cultural understandings of mental health and illness. The "negotiated space" is a place ofp urposive re-encounter reconstructing and re-balancing of ideas and values in complementary realignments that have resonance for Pacific peoples living in Western oriented societies. This requires making explicit the competing epistemologies of the Pacific indigenous worldviews and references alongside the bio-psycho-social and identifying the assumptions implicit in the operating logic ofe ach. This is a precursor to being empowered to negotiate, resolve and better comprehend the cultural conflict between the different understandings. This article theorises multiple patterns of possibility of resolutions and relationships within the negotiated space relevant to research, evaluation, model, service development and quality assurance within Pacific mental health.

    Charged particle beam therapy has been used for almost 60 years. During the initial 40 years, the medical use of protons and heavy ions was explored at accelerator laboratories in a limited number of patients and for a limited number of cancerous and non-cancerous disease conditions. After the development of computed tomography and 3D treatment planning, it was time to move charged particle therapy into the clinical realm. This happened in October 1991 when an ocular melanoma patient became the first patient to be treated at Loma Linda University Medical Center in California. Due to the increased awareness of the advantages of charged particle therapy and promising results of single-institution experiences, one currently observes a phase of rapid expansion of proton treatment centers throughout the world. A few of these centers are combined proton/carbon ion facilities. It is very important that the technological evolution of charged particle therapy will continue during this phase of clinical expansion to ensure that the increasing number of patients exposed to therapeutic charged particles will benefit most from the advantageous dose distributions that these particles afford. This report will give an overview of translational research activities related to planning and verification of proton therapy in which the authors have been involved for a number of years. While our activities focus on protons, these developments are to a large degree also applicable to carbon ion therapy. PMID:25520941

    A second observatory of the Telescopes in Education (TIE) project is in the planning stages, with hopes to be in use by fall 1998. The Little Thompson Observatory will be located adjacent to Berthoud High School in northern Colorado. TIE has offered the observatory a Tinsley 18" Cassegrain telescope on a 10-year loan. Local schools and youth organizations will have prioritized access to the telescope until midnight; after that, the telescope will be open to world-wide use by schools via the Internet. The first TIE observatory is a 24" telescope on Mt. Wilson, already booked through July 1998. That telescope has been in use every clear night for the past four years by up to 50 schools per month. Students remotely control the telescope over the Internet, and then receive the images on their local computers. The estimated cost of the Little Thompson Observatory is roughly \\170,000. However, donations of labor and materials have reduced the final price tag closer to \\40,000. Habitat for Humanity is organized to construct the dome, classrooms, and other facilities. Tom and Linda Melsheimer, who developed the remote telescope control system for the University of Denver's Mount Evans Observatory, are donating a similar control system. The formally-trained, all-volunteer staff will be comprised of local residents, teachers and amateur astronomers. Utilities and Internet access will be provided by the Thompson School District.

    To build capacity and collaborative research for future cross-national studies in the Asian and Pacific Islander (API) region, priority research topics were identified and discussed at the April 2013 Conference to Promote Global Health in Taipei. These topics included (1) Neuroscience on HIV/HCV and amphetamine-type stimulants (ATS), led by Drs. Linda Chang, Gene-Jack Wang, and Betty Tai; (2) ATS and mental health disorders, led by Drs. Richard Rawson and Wilson Compton; and (3) HIV/HCV transmission and social networks, led by Drs. Steven Shoptaw and Jacques Normand. Potential genetic studies spanning these topical areas as well as the importance of smoking cessation were further discussed, led by Dr. Ming Li. Additional priority research topics were also identified: (4) Drug use prevention, and (5) Family involvement to improve treatment adherence and recovery. Workgroups on these topics will be formed to prioritize research questions within the respective topical area and to determine the next steps. The ultimate goal of these workgroups is to stimulate collaboration that will eventually lead to research studies addressing critical issues related to the rising substance abuse and HIV infection rates in many Asian countries and, at the same time, to advance the scientific knowledge of substance abuse and HIV infection.

    Since the high energy accelerator plan was changed from a 40 GeV direct machine to a 12GeV cascade one, a 500 MeV rapid cycling booster synchrotron was installed between the injector linac and the 12 GeV main ring at KEK, National Lab. for High Energy Physics. The booster beams were used not only for injection to the main ring but also for medical use. Their energy was reduced to 250 MeV by a graphite block for clinical trial of cancer therapy. In 1970's, pi(-) or heavy ions were supposed to be promising. Although advantage of protons with Bragg Peak was pointed out earlier, they seemed effective only for eye melanoma at that time. In early 1980's, it was shown that they were effective for deep-seated tumor by Tsukuba University with KEK beams. The first dedicated facility was built at Loma Linda University Medical Center. Its synchrotron was made by Fermi National Accelerator Lab. Since a non-resonant accelerating rf cavity was installed, operation of the synchrotron became much easier. Later, innovation of the cyclotron was achieved. Its weight was reduced from 1,000 ton to 200 ton. Some of the cyclotrons are equipped with superconducting coils.

    This manuscript summarizes the proceedings of the symposium entitled, “Stress, Palatable Food and Reward”, that was chaired by Drs. Linda Rinaman and Yvonne Ulrich-Lai at the 2014 Neurobiology of Stress Workshop held in Cincinnati, OH. This symposium comprised research presentations by four neuroscientists whose work focuses on the biological bases for complex interactions among stress, food intake and emotion. First, Dr. Ulrich-Lai describes her rodent research exploring mechanisms by which the rewarding properties of sweet palatable foods confer stress relief. Second, Dr. Stephanie Fulton discusses her work in which excessive, long-term intake of dietary lipids, as well as their subsequent withdrawal, promotes stress-related outcomes in mice. Third, Dr. Mark Wilson describes his group’s research examining the effects of social hierarchy-related stress on food intake and diet choice in group-housed female rhesus macaques, and compared the data from monkeys to results obtained in analogous work using rodents. Lastly, Dr. Gorica Petrovich discusses her research program that is aimed at defining cortical–amygdalar–hypothalamic circuitry responsible for curbing food intake during emotional threat (i.e., fear anticipation) in rats. Their collective results reveal the complexity of physiological and behavioral interactions that link stress, food intake and emotional state, and suggest new avenues of research to probe the impact of genetic, metabolic, social, experiential, and environmental factors.

    The primary objective of this study was to determine whether the incidence of chromosome aberrations in peripheral lymphocytes of young adults emigrating from and immigrating to an area with perpetually high levels of photochemical air pollutants versus an area of low levels differed significantly from students indigenous to the respective areas. Three hundred and ninety-eight male and female first-year students at the La Sierra campus of Loma Linda University (high smog) and Pacific Union College (low smog) were preenrolled after completing a lifestyle questionnaire or responding to a similar telephone-administered questionnaire. They were assigned to groups according to their previous lifetime exposure to air pollution and the college in which they were matriculating. Blood samples and updated health histories were obtained from the students during September and November 1976. One hundred cells from each student were analyzed for chromosome and chromatid abberations. No statistically significant differences in the aberrates rates for the types of chromosome abnormalities studied were observed between the four exposure groups of students at each of the sampling periods or among the same students over the duration of the study. An exception of statistical significance was the elevated rate of stable changes in the initial blood sampling period for males in the low-to-high exposure group who had arrived on campus within 3 days of the blood sampling.

    2011-05-05

    Due to the success of theoretical track structure Monte Carlo simulations, showing that features of ionization patterns on the nanometer level are important for the biological effectiveness of ionizing radiation, several new methods for experimental track structure investigations have been developed in recent years. These methods all use the principle of density scaling in low-pressure gas to probe track structure in macroscopic dimensions, ideally with single-ionization resolution. The new field of experimental track structure investigation, which has been called nanodosimetry, can be approached in two ways: (1) the number of ionizations in a defined, ideally wall-less, sensitive volume is registered per single primary particle and cluster size distributions are obtained, or (2) the full track structure of an ion track segment is 'imaged'. Existing nanodosimetric methods are based on the first approach, but a track structure imaging detector is currently under development at Loma Linda University. This contribution will review the principle and existing technical approaches to nanodosimetry and will give an outlook on future developments and applications.

    Future space missions will involve long-term travel beyond the magnetic field of the Earth, where astronauts will be exposed to radiation hazards such as those that arise from galactic cosmic rays. Galactic cosmic rays are composed of protons, alpha particles, and particles of high energy and charge (HZE particles). Research by our group has shown that exposure to HZE particles, primarily 600 MeV/n and 1 GeV/n 56Fe, can produce significant alterations in brain neurochemistry and behavior. However, given that protons can make up a significant portion of the radiation spectrum, it is important to study their effects on neural functioning and on related performance. Therefore, these studies examined the effects of exposure to proton irradiation on neurochemical and behavioral endpoints, including dopaminergic functioning, amphetamine-induced conditioned taste aversion learning, and spatial learning and memory as measured by the Morris water maze. Male Sprague-Dawley rats received a dose of 0, 1.5, 3.0 or 4.0 Gy of 250 MeV protons at Loma Linda University and were tested in the different behavioral tests at various times following exposure. Results showed that there was no effect of proton irradiation at any dose on any of the endpoints measured. Therefore, there is a contrast between the insignificant effects of high dose proton exposure and the dramatic effectiveness of low dose (<0.1 Gy) exposures to 56Fe particles on both neurochemical and behavioral endpoints.

    Proton radiography has applications in patient alignment and verification procedures for proton beam radiation therapy. In this paper, we report an experiment which used 200 MeV protons to generate proton energy-loss and scattering radiographs of a hand phantom. The experiment used the first-generation proton computed tomography (CT) scanner prototype, which was installed on the research beam line of the clinical proton synchrotron at Loma Linda University Medical Center. It was found that while both radiographs displayed anatomical details of the hand phantom, the energy-loss radiograph had a noticeably higher resolution. Nonetheless, scattering radiography may yield more contrast between soft and bone tissue than energy-loss radiography, however, this requires further study. This study contributes to the optimization of the performance of the next-generation of clinical proton CT scanners. Furthermore, it demonstrates the potential of proton imaging (proton radiography and CT), which is now within reach of becoming available as a new, potentially low-dose medical imaging modality.

  15. A modular approach to modeling an isolated power system on a finite voltage bus using a differential algebraic equation solving routine

    Kipps, Mark R.

    1994-03-01

    The modeling of power systems has been primarily driven by the commercial power utility industry. These models usually involve the assumption that system bus voltage and frequency are constant. However, in applications such as shipboard power systems this infinite bus assumption is not valid. This thesis investigates the modeling of a synchronous generator and various loads in a modular fashion on a finite bus. The simulation presented allows the interconnection of multiple state-space models via a bus voltage model. The major difficulty encountered in building a model which computes bus voltage at each time step is that bus voltage is a function of current and current derivative terms. Bus voltage is also an input to the state equations which produce the current and current derivatives. This creates an algebraic loop which is a form of implicit differential equation. A routine has been developed by Linda Petzold of Lawrence Livermore Laboratory for solving these types of equations. The routine, called Differential Algebraic System Solver (DASSL), has been implemented in a pre-release version of the software Advanced Continuous Simulation Language (ACSL) and has been made available to the Naval Postgraduate School on a trial basis. An isolated power system is modeled using this software and the DASSL routine. The system response to several dynamic situations is studied and the results are presented.

    Universal access to oral health care is a justifiable demand for a number of disparate but morally sound reasons. Nevertheless, that conclusion, however reached, has not solved the problem of the lack of access. Market forces, scarcity of funding, and lack of clarity as to who is responsible for ensuring that oral care is available seem to present insurmountable difficulties. I shall argue that these are not irresolvable problems, but the resolution has to take place through the tool of systems thinking and a systemic approach to moral imagination. Taking the lead from Susan Wolf's and Linda Emanuel's work on systems thinking, and developing ideas from work on mental models and moral imagination, I shall argue that what is often missing in discussions and demands for universal access to oral health care is a morally imaginative systemic approach that takes into account the multi-perspective dynamics involved in health care today. Moral imagination may encourage sound, broad-based, more inclusive moral thinking and moral judgment without ignoring the critical roles and responsibilities each of us has as professionals, providers, payers, or patients, without which change will not take place at all.

    The objective of apical surgery is to retain teeth with persistent apical pathosis following orthograde root canal treatment if endodontic non-surgical revision is difficult or associated with risks, or is even declined by the patient. Since the most frequent cause of recurrent apical disease is bacterial reinfection from the (remaining) root canal system, the bacteria-tight root-end filling is the most important step in apical surgery. In the early 1990s, mineral trioxide aggregate (MTA) was developed at the Loma Linda University in California/USA. Preclinical studies clearly showed that MTA has a high sealing capability, a good material stability and an excellent biocompatbility. Multiple experimental studies in animals highlighted the mild tissue reactions observed adjacent to this material. Furthermore, histological analysis of the periapical regions demonstrated a frequent deposition of new cementum not only onto the resection plane (cut dentinal surface), but also directly onto MTA. For these reasons, MTA is considered a bioactive material. In 1997 MTA was cleared for clinical use in patients. Multiple prospective clinical and randomized studies have documented high and constant success rates of MTA-treated teeth in apical surgery. A recently published longitudinal study showed that MTA-treated teeth remained stable over five years; hence the high healed rates documented after one year are maintained during long-term observation.

    The space environment consists of energetic particles of varying mass and energy, and understanding the :biological Bragg curve" is essential in optimizing shielding effectiveness against space radiation induced biological impacts. The "biological Bragg curve" is dependent on the energy and the type of the primary particle, and may vary for different biological endpoints. Previously, we studied the induction of micronuclei (MN) across the Bragg curve of energetic Fe and Si ions, and observed no increased yield of MN at the location of the Bragg peak. However, the ratio of mono- to bi-nucleated cells, which indicates inhibition of cell progression, was found higher at the Bragg peak location in comparison to the plateau region of the Bragg curve. Here, we report the induction of MN in normal human fibroblast cells across the Bragg curve of incident protons generated at Loma Linda University. Similar to Si and Fe ions, the ratio of mono- to bi-nucleated cells showed a clear spike as the protons reached the Bragg peak. Unlike the two heavy ions, however, the MN yield also increased at the Bragg peak location. These results confirm the hypothesis that severely damaged cells at the Bragg peak of heavy, but not light ions are more likely to go through reproductive death and not be evaluated for micronuclei.

    Future space missions will involve long-term travel beyond the magnetic field of the Earth, where astronauts will be exposed to radiation hazards such as those that arise from galactic cosmic rays. Galactic cosmic rays are composed of protons, alpha particles, and particles of high energy and charge (HZE particles). Research by our group has shown that exposure to HZE particles, primarily 600 MeV/n and 1 GeV/n 56Fe, can produce significant alterations in brain neurochemistry and behavior. However, given that protons can make up a significant portion of the radiation spectrum, it is important to study their effects on neural functioning and on related performance. Therefore, these studies examined the effects of exposure to proton irradiation on neurochemical and behavioral endpoints, including dopaminergic functioning, amphetamine-induced conditioned taste aversion learning, and spatial learning and memory as measured by the Morris water maze. Male Sprague-Dawley rats received a dose of 0, 1.5, 3.0 or 4.0 Gy of 250 MeV protons at Loma Linda University and were tested in the different behavioral tests at various times following exposure. Results showed that there was no effect of proton irradiation at any dose on any of the endpoints measured. Therefore, there is a contrast between the insignificant effects of high dose proton exposure and the dramatic effectiveness of low dose (<0.1 Gy) exposures to 56Fe particles on both neurochemical and behavioral endpoints.

    From October 18 to 20, 2006, a symposium, Developing and Understanding a Hospital-based Proton Facility: Bringing Physics Into Medicine, was held at the Renaissance Esmeralda Resort and Spa, Indian Wells, California. The event was offered by the Department of Radiation Medicine at Loma Linda University (LLU), supported by the Telemedicine and Advanced Technology Research Center (TATRC) and the United States Army Medical Research and Materiel Command (USAMRMC). The meeting was intended to discuss factors involved in planning, developing, and operating a hospital-based proton treatment center. It brought together some of the most distinguished physicists, radiation biologists, and radiation oncologists in the world, and more than 100 individuals participated in the three-day educational offering. This overview reports on the event and introduces several papers written by many of the speakers from their presentations, for publication in this issue of Technology in Cancer Research and Treatment. Both the symposium and the papers are appropriate for this journal: exploitation of technology was one of the underlying themes of the symposium.

    This manuscript summarizes the proceedings of the symposium entitled, "Stress, Palatable Food and Reward", that was chaired by Drs. Linda Rinaman and Yvonne Ulrich-Lai at the 2014 Neurobiology of Stress Workshop held in Cincinnati, OH. This symposium comprised research presentations by four neuroscientists whose work focuses on the biological bases for complex interactions among stress, food intake and emotion. First, Dr Ulrich-Lai describes her rodent research exploring mechanisms by which the rewarding properties of sweet palatable foods confer stress relief. Second, Dr Stephanie Fulton discusses her work in which excessive, long-term intake of dietary lipids, as well as their subsequent withdrawal, promotes stress-related outcomes in mice. Third, Dr Mark Wilson describes his group's research examining the effects of social hierarchy-related stress on food intake and diet choice in group-housed female rhesus macaques, and compared the data from monkeys to results obtained in analogous work using rodents. Finally, Dr Gorica Petrovich discusses her research program that is aimed at defining cortical-amygdalar-hypothalamic circuitry responsible for curbing food intake during emotional threat (i.e. fear anticipation) in rats. Their collective results reveal the complexity of physiological and behavioral interactions that link stress, food intake and emotional state, and suggest new avenues of research to probe the impact of genetic, metabolic, social, experiential and environmental factors on these interactions.

  6. Neural relativity principle

    Olfaction is the final frontier of our senses - the one that is still almost completely mysterious to us. Despite extensive genetic and perceptual data, and a strong push to solve the neural coding problem, fundamental questions about the sense of smell remain unresolved. Unlike vision and hearing, where relatively straightforward relationships between stimulus features and neural responses have been foundational to our understanding sensory processing, it has been difficult to quantify the properties of odorant molecules that lead to olfactory percepts. In a sense, we do not have olfactory analogs of ``red'', ``green'' and ``blue''. The seminal work of Linda Buck and Richard Axel identified a diverse family of about 1000 receptor molecules that serve as odorant sensors in the nose. However, the properties of smells that these receptors detect remain a mystery. I will review our current understanding of the molecular properties important to the olfactory system. I will also describe a theory that explains how odorant identity can be preserved despite substantial changes in the odorant concentration.

    The 2004 Nobel Prize for Physiology or Medicine has been awarded to Richard Axel and Linda B. Buck, for their discovery of smell receptors and the organisation of the olfactory system. Their original discovery concerned the identification of some 1000 genes that code for smell receptors in the olfactory epithelium of the rat. They also demonstrated that each receptor can only be activated by a limited number of odourants and that there is some overlap in specificity with other smell receptors. Odourants in inhaled air are specifically recognized and bound by the smell receptors on the olfactory neurones in the nasal epithelium. The activated neurones send an electrical signal to the mitral cells, the dendrites of which lie in the glomeruli of the olfactory bulb. In each olfactory neuron only one smell receptor gene is expressed. Neurones with the same type of receptor are spread throughout the epithelium but converge in the same glomerulus. An olfactory map is formed by means of mitral-cell projections which run to the cerebral cortex as well as to other parts of the brain. Possibly the information gained about odourants will be applied in the areas of physiology and pathophysiology; in the field of pharmacology for example where odourants may be used in the treatment of disorders of fertility, behaviour or mood.

    Many US combat personnel have sustained nervous tissue trauma during service, which often causes Neuropathic pain as a side effect and is difficult to manage. However in select patients, synapse lesioning can provide significant pain control. Our goal is to determine the effectiveness of using Proton Beam radiotherapy for treating spinal cord injury (SCI) related neuropathic pain as an alternative to invasive surgical lesioning. The project is a joint collaboration of USC, Spinal Cord Institute VA Healthcare System, Long Beach, and Loma Linda University. This is first system of its kind that supports integration and standardization of imaging informatics data in DICOM format; clinical evaluation forms outcomes data and treatment planning data from the Treatment planning station (TPS) utilized to administer the proton therapy in DICOM-RT format. It also supports evaluation of SCI subjects for recruitment into the clinical study, which includes the development, and integration of digital forms and tools for automatic evaluation and classification of SCI pain. Last year, we presented the concept for the patient recruitment module based on the principle of Bayesian decision theory. This year we are presenting the fully developed patient recruitment module and its integration to other modules. In addition, the DICOM module for integrating DICOM and DICOM-RT-ION data is also developed and integrated. This allows researchers to upload animal/patient study data into the system. The patient recruitment module has been tested using 25 retrospective patient data and DICOM data module is tested using 5 sets of animal data.

The crew is seen flying into Kennedy Space Center, suiting up, boarding the Endeavour Orbiter, and during launch. Various mission highlights are seen, including the rendezvous with the International Space Station (ISS) and docking of Endeavour, the unloading of the Multipurpose Logistics Module (MPLM), and the spacewalk to install thermal blankets over the Beta Gimbal Assemblies (BGAs) at the bases of the Space Station's solar panels. A glimpse is given into the difficulties of working in a microgravity environment as the crewmembers attempt to eat food before it floats away from them and drink water from a bag. The exchange of the Expedition 4 (Yuri I. Onufrienko, Carl E. Walz, and Daniel W. Bursch) for the Expedition 3 crew (Frank L. Culbertson, Mikhail Turin, and Vladimir N. Dezhurov) is also seen. The Endeavour undocks from the ISS, which is seen over the Caribbean Sea. Endeavour passes over Cuba, and footage of the Swiss Alps is shown. The video ends with the landing of the spacecraft.

    Much remains unknown about the genetic status and population connectivity of high-elevation and high-latitude freshwater invertebrates, which often persist near snow and ice masses that are disappearing due to climate change. Here we report on the conservation genetics of the meltwater stonefly Lednia tumana (Ricker) of Montana, USA, a cold-water obligate species. We sequenced 1530 bp of mtDNA from 116 L. tumana individuals representing “historic” (>10 yr old) and 2010 populations. The dominant haplotype was common in both time periods, while the second-most-common haplotype was found only in historic samples, having been lost in the interim. The 2010 populations also showed reduced gene and nucleotide diversity and increased genetic isolation. We found lower genetic diversity in L. tumana compared to two other North American stonefly species, Amphinemura linda (Ricker) and Pteronarcys californica Newport. Our results imply small effective sizes, increased fragmentation, limited gene flow, and loss of genetic variation among contemporary L. tumana populations, which can lead to reduced adaptive capacity and increased extinction risk. This study reinforces concerns that ongoing glacier loss threatens the persistence of L. tumana, and provides baseline data and analysis of how future environmental change could impact populations of similar organisms.

    JSC researchers study carcinogenesis, cancer prevention and treatment along with epidemiological (primarily retrospective and longitudinal) studies, modeling, and interactions with the environment such as radiation, nutritional, and endocrine changes related to space flight along with behaviors such as smoking. Cancer research is a major focus for human space flight due to the exposure to space radiation which consists of particles of varying charges and energies, and secondary neutrons. The JSC laboratories collaborate with investigators from the U.S. as well as our European and Japanese partners. We use accelerator facilities at the Brookhaven National Laboratory, Loma Linda University and Los Alamos National Laboratory that generate high energy charged particles and neutrons to simulate cosmic radiation and solar particle events. The research using cultured cells and animals concentrates on damage and repair from the level of DNA to organ tissues, due to exposure to simulated space radiation exposure, that contribute to the induction of leukemia and solid tumors in most major tissues such as lung, colon, liver and breast. The goal of the research is to develop a mathematical model that can predict cancer morbidity and mortality risks with sufficient accuracy for a given space mission.

    Proton radiography has applications in patient alignment and verification procedures for proton beam radiation therapy. In this paper, we report an experiment which used 200 MeV protons to generate proton energy-loss and scattering radiographs of a hand phantom. The experiment used the first-generation proton CT scanner prototype, which was installed on the research beam line of the clinical proton synchrotron at Loma Linda University Medical Center (LLUMC). It was found that while both radiographs displayed anatomical details of the hand phantom, the energy-loss radiograph had a noticeably higher resolution. Nonetheless, scattering radiography may yield more contrast between soft and bone tissue than energy-loss radiography, however, this requires further study. This study contributes to the optimization of the performance of the next-generation of clinical proton CT scanners. Furthermore, it demonstrates the potential of proton imaging (proton radiography and CT), which is now within reach of becoming available as a new, potentially low-dose medical imaging modality.

    Recent developments in NASA s deterministic High charge (Z) and Energy TRaNsport (HZETRN) code have included lateral broadening of primary ion beams due to small-angle multiple Coulomb scattering, and coupling of the ion-nuclear scattering interactions with energy loss and straggling. This new version of HZETRN is based on Green function methods, called GRNTRN, and is suitable for modeling transport with both space environment and laboratory boundary conditions. Multiple scattering processes are a necessary extension to GRNTRN in order to accurately model ion beam experiments, to simulate the physical and biological-effective radiation dose, and to develop new methods and strategies for light ion radiation therapy. In this paper we compare GRNTRN simulations of proton lateral broadening distributions with beam measurements taken at Loma Linda University Proton Therapy Facility. The simulated and measured lateral broadening distributions are compared for a 250 MeV proton beam on aluminum, polyethylene, polystyrene, bone substitute, iron, and lead target materials. The GRNTRN results are also compared to simulations from the Monte Carlo MCNPX code for the same projectile-target combinations described above.

    Sleep is essential for the health of the nervous system. Lack of sleep has a profound negative effect on cognitive ability and task performance. During sustained military operations, soldiers often suffer from decreased quality and quantity of sleep, increasing their susceptibility to neurological problems and limiting their ability to perform the challenging mental tasks that their missions require. In the civilian sector, inadequate sleep and overt sleep pathology are becoming more common, with many detrimental impacts. There is a strong need for new, in vivo studies of human brains during sleep, particularly the initial descent from wakefulness. Our research team is investigating sleep using a combination of magnetic resonance imaging (MRI), positron emission tomography (PET), and electroencephalography (EEG). High resolution MRI combined with PET enables localization of biochemical processes (e.g., metabolism) to anatomical structures. MRI methods can also be used to examine functional connectivity among brain regions. Neural networks are dynamically reordered during different sleep stages, reflecting the disconnect with the waking world and the essential yet unconscious brain activity that occurs during sleep.[4pt] In collaboration with Linda Larson-Prior, Washington University; Alpay Ozcan, Virginia Tech; Seong Mun, Virginia Tech; and Zang-Hee Cho, Gachon University.

    of sustainable energy provides an opportunity for expanded involvement with industrial research. We were privileged to recruit several outstanding new leaders at the APS. Linda Young, from Argonne's Chemical Sciences Division, became the new Director of the X-ray Science Division (XSD). Chris Jacobsen (from Stony Brook University) has been added to Linda's team as an XSD Associate Division Director, joining George Srajer. Alexander (Sasha) Zholents (formerly of Berkeley Lab) became Director of the Accelerator Systems Division. Sasha is the inventor of the short-pulse x-ray scheme that we plan to implement in the APS-U to obtain very high average brightness, broadband, 1-ps x-ray pulses. Walter Lowe (formerly of Howard University) has taken a new position as senior advisor for outreach and development of the user community. Walter's role is to increase the diversity of the user community (with diversity read broadly to include users, institutions, and technical disciplines that are underrepresented at APS). Walter is also leading an effort to increase access for industrial users. I am confident that we have in place a great team to help our users and the APS take fullest advantage of the APS-U opportunity. In planning with users for the proposed APS-U, we focused on the need to study 'real materials under real conditions in real time' on spatial and temporal scales unavailable today. Only by studying materials as they are made-or as they perform-in difficult environments can we solve the grand challenge of higher-performance, sustainable materials for energy and health. The proposed APS-U will improve the brightness of penetrating x-rays produced by the APS over 100 times, and support our efforts in developing state-of-the-art instruments to address these challenges.

  20. Gastroschisis: a simple technique for staged silo closure.

    1995-08-01

    In conjunction with the Neonatology Department at Loma Linda University Children's Hospital, a new protocol has evolved for the management of infants with gastroschisis, which obviates both risks associated with primary and staged silo closure. After stabilization of the infant in the neonatal intensive care unit, under sterile conditions, a 5- or 7-cm SILASTIC silo with a spring-loaded ring is placed over the exposed viscera, under the fascial defect. No sutures are required. A fentanyl drip is given, and the bowel is gradually reduced over the next few days. The transparent material of the silo allows for continuous monitoring of the condition of the bowel. Second-stage closure in the operating room is performed using a purse-string suture in the fascia to create a pseudoumbilicus. From October 1992 to April 1994 the authors managed 10 infants using this protocol. The results are compared with those of infants with gastroschisis treated at the same institution between August 1982 and June 1993. Outcome parameters to be compared include time until closure, time on ventilation, days of total parenteral nutrition, time until start of oral feeding, time until toleration of full-volume oral feeding, and time until discharge. The authors conclude that silo closure in the neonatal intensive care unit is simple, quick, and effective. It eliminates multiple trips to the operating room, allows the natural accommodation of the bowel into the abdominal cavity with little edema and minimal vascular compromise, and has become the authors' treatment of choice for infants with gastroschisis.

  1. HUBBLE MEASURES VELOCITY OF GAS ORBITING BLACK HOLE

    NASA Technical Reports Server (NTRS)

    2002-01-01

    A schematic diagram of velocity measurements of a rotating disk of hot gas in the core of active galaxy M87. The measurement was made by studying how the light from the disk is redshifted and blueshifted -- as part of the swirling disk spins in earth's direction and the other side spins away from earth. The gas on one side of the disk is speeding away from Earth, at a speed of about 1.2 million miles per hour (550 kilometers per second). The gas on the other side of the disk is orbiting around at the same speed, but in the opposite direction, as it approaches viewers on Earth. This high velocity is the signature of the tremendous gravitational field at the center of M87. This is clear evidence that the region harbors a massive black hole, since it contains only a fraction of the number of stars that would be necessary to create such a powerful attraction. A black hole is an object that is so massive yet compact nothing can escape its gravitational pull, not even light. The object at the center of M87 fits that description.

    Reported herein are results from the Eril Research, Inc.(ERI) participationin the NASA Johnson Space Center sponsored studycharacterizing the radiation shielding properties of the two types ofspace suit that astronauts are wearing during the EVA on-orbit assemblyof the International Space Station (ISS). Measurements using passivedetectors were carried out to assess the shielding properties of the USEMU Suit and the Russian Orlan-M suit during irradiations of the suitsand a tissue equivalent phantom to monoenergetic proton and electronbeams at the Loma Linda University Medical Center (LLUMC). Duringirradiations of 6 MeV electrons and 60 MeV protons, absorbed dose as afunction of depth was measured using TLDs exposed behind swatches of thetwo suit materials and inside the two EVA helmets. Considerable reductionin electron dosewas measured behind all suit materials in exposures to 6MeV electrons. Slowing of the proton beam in the suit materials led to anincrease in dose measured in exposures to 60 MeV protons. During 232 MeVproton irradiations, measurements were made with TLDs and CR-39 PNTDs atfive organ locations inside a tissue equivalent phantom, exposed bothwith and without the two EVA suits. The EVA helmets produce a 13 to 27percent reduction in total dose and a 0 to 25 percent reduction in doseequivalent when compared to measurements made in the phantom head alone.Differences in dose and dose equivalent between the suit and non-suitirradiations forthe lower portions of the two EVA suits tended to besmaller. Proton-induced target fragmentation was found to be asignificant source of increased dose equivalent, especially within thetwo EVA helmets, and average quality factor inside the EMU and Orlan-Mhelmets was 2 to 14 percent greater than that measured in the barephantom head.

  3. Modeling and identification of multistory buildings with seismic recordings

    NASA Astrophysics Data System (ADS)

    Gargab, Lotfi O.

    This study proposes a continuous-discrete model for one-dimensional wave propagation in a multi-story building with seismic excitation and shows its applications in forward predicting analysis and inverse system identification. In particular, the building is modeled as a series of continuous shear-beams for columns/walls in inter-stories and discrete lumped-masses for floors. Wave response at one location of the building is then derived from an impulsive motion at another location in the time and frequency domains, termed here as wave-based or generalized impulse and frequency response functions (GIRF and GFRF). The GIRF and GFRF are fundamental in relating seismic wave responses at the two locations of a building structure subjected to seismic excitation that is not fully known due to the complicated soil-structure interaction. Additionally, they play a key role in characterizing seismic structural responses, as well as in identifying dynamic parameters and subsequently diagnosing local damage of the structure. For illustration, this study examines the ten-story Millikan Library in Pasadena, California with recordings of the Yorba Linda earthquake of September 3, 2002. With the use of the proposed continuous-discrete model as well as its degenerated ones, seismic wave responses are interpreted from the perspective of wave propagation, and more importantly, validated with the recordings and pertinent discrete-model-based results. Finally, a wave-based approach for system identification with a limited number of seismic recordings is presented, which can be used to evaluate structural integrity and detect damage in post-earthquake structural condition assessment.

    Fourteen kilometers of continuous, shallow seismic reflection data acquired through the urbanized San Bernardino Valley, California, have revealed numerous faults between the San Jacinto and San Andreas faults as well as a complex pattern of downdropped and uplifted blocks. These data also indicate that the Loma Linda fault continues northeastward at least 4.5 km beyond its last mapped location on the southern edge of the valley and to within at least 2 km of downtown San Bernardino. Previously undetected faults within the valley northeast of the San Jacinto fault are also imaged, including the inferred western extension of the Banning fault and several unnamed faults. The Rialto-Colton fault is interpreted southwest of the San Jacinto fault. The seismic data image the top of the crystalline basement complex across 70% of the profile length and show that the basement has an overall dip of roughly 10?? southwest between Perris Hill and the San Jacinto fault. Gravity and aeromagnetic data corroborate the interpreted location of the San Jacinto fault and better constrain the basin depth along the seismic profile to be as deep as 1.7 km. These data also corroborate other fault locations and the general dip of the basement surface. At least 1.2 km of apparent vertical displacement on the basement is observed across the San Jacinto fault at the profile location. The basin geometry delineated by these data was used to generate modeled ground motions that show peak horizontal amplifications of 2-3.5 above bedrock response in the 0.05- to 1.0-Hz frequency band, which is consistent with recorded earthquake data in the valley.

  5. Control Algorithms Charge Batteries Faster

    On March 29, 2011, NASA s Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) spacecraft beamed a milestone image to Earth: the first photo of Mercury taken from orbit around the solar system s innermost planet. (MESSENGER is also the first spacecraft to orbit Mercury.) Like most of NASA s deep space probes, MESSENGER is enabled by a complex power system that allows its science instruments and communications to function continuously as it travels millions of miles from Earth. "Typically, there isn't one particular power source that can support the entire mission," says Linda Taylor, electrical engineer in Glenn Research Center s Power Systems Analysis Branch. "If you have solar arrays and you are in orbit, at some point you re going to be in eclipse." Because of this, Taylor explains, spacecraft like MESSENGER feature hybrid power systems. MESSENGER is powered by a two-panel solar array coupled with a nickel hydrogen battery. The solar arrays provide energy to the probe and charge the battery; when the spacecraft s orbit carries it behind Mercury and out of the Sun s light, the spacecraft switches to battery power to continue operations. Typically, hybrid systems with multiple power inputs and a battery acting alternately as storage and a power source require multiple converters to handle the power flow between the devices, Taylor says. (Power converters change the qualities of electrical energy, such as from alternating current to direct current, or between different levels of voltage or frequency.) This contributes to a pair of major concerns for spacecraft design. "Weight and size are big drivers for any space application," Taylor says, noting that every pound added to a space vehicle incurs significant costs. For an innovative solution to managing power flows in a lightweight, cost-effective manner, NASA turned to a private industry partner.

  6. HUBBLE OBSERVES SPIRAL GAS DISK IN ACTIVE GALAXY

    2002-01-01

    A NASA Hubble Space Telescope image of a spiral-shaped disk of hot gas in the core of active galaxy M87. HST measurements show the disk is rotating so rapidly it contains a massive black hole at its hub. A black hole is an object that is so massive yet compact nothing can escape its gravitational pull, not even light. The object at the center of M87 fits that description. It weights as much as three billion suns, but is concentrated into a space no larger than our solar system. Now that astronomers have seen the signature of the tremendous gravitational field at the center of M87, it is clear that the region contains only a fraction of the number of stars that would be necessary to create such a powerful attraction. The giant elliptical galaxy M87 is located 50 million light-years away in the constellation Virgo. Earlier observations suggested the black hole was present, but were not decisive. A brilliant jet of high- speed electrons that emits from the nucleus (diagonal line across image) is believed to be produced by the black hole 'engine.' The image was taken with HST's Wide Field Planetary Camera 2 Credit: Holland Ford, Space Telescope Science Institute/Johns Hopkins University; Richard Harms, Applied Research Corp.; Zlatan Tsvetanov, Arthur Davidsen, and Gerard Kriss at Johns Hopkins; Ralph Bohlin and George Hartig at Space Telescope Science Institute; Linda Dressel and Ajay K.

  7. Minnesota court overturns ban on Medicaid coverage for abortion.

    1994-06-24

    Hennipin County District Court Judge William Posten issued a decision on June 16 striking down Minnesota's near ban on abortion coverage for low-income women. Ruling in Women of the State of Minnesota vs. Haas-Steffen, Judge Posten found that the state Constitution's rights of privacy and equality are more protective of women's reproductive choices than the corresponding federal rights. Holding that "the state's selective funding of childbirth over abortion impinges on an indigent woman's fundamental right to decide for herself whether to continue or terminate her pregnancy," the state district court permanently enjoined enforcement of the measure. Minnesota must now cover all medically necessary abortions for women receiving Medicaid. For more than 15 years, the statutes and regulations invalidated by Judge Posten have limited abortion coverage to cases of life endangerment or reported rape or incest. State officials have indicated that they will seek a stay and expedited review of Judge Posten's decision from the Minnesota Supreme Court. Filed on March 8, 1993, the Minnesota case is one of 5 such lawsuits brought by CRLP. Last December, in a similar case, the West Virginia Supreme Court struck down that state's ban on Medicaid coverage for abortions. Similar CRLP cases are still pending in Florida, Texas, and Montana. Plaintiffs--a class of Minnesota Medicaid-eligible women seeking abortions, Dr. Jane Hodgson, Pro-Choice Resources, Women's Health Center, Midwest Health Center for Women, and Meadowbrook Women's Clinic, on behalf of themselves and the women they serve--are represented by CRLP's Simon Heller, Janet Benshoof, and Lenora Lapidus, along with Minnesota attorney Linda Ojala.

    Dr. France Cordova, NASA's Chief Scientist opened this, the third session in the NASA Administrator's Seminar Series, by asking the following question: 'What would be a bold and aspiring agenda for America's next era in space?' It aimed at answering the following questions: What do we know about the universe? How do we know it? (Dr. Cordova also mentioned that the first seminar was about the definition of cellular life and how to recognize it, and featured as speakers, Dr. Lynn Margoles and Dr. Leslie Orgle.) Administrator Daniel S. Goldin was introduced; he welcomed the attendees, and remarked that NASA personnel have a critical need to explain to Congress and the public why a space program is important. Congress and the public pay for the space programs. Therefore the programs' importance cannot remain in the sole domain of scientists. The first speaker, Dr. Vera Ruben of the Department of Terrestrial Magnetism at the Carnegie Institute of Washington, was introduced as an art historian expert in cosmology and an observational astronomer. Dr. Ruben brought up a number of questions regarding the substance, location, and origin of dark matter, radiation, galaxies, and the lumpy structure of galaxies in space, as well as the age and density of our universe. The next speaker was Dr. Bohdan Paczynski, a theoretical astrophysicist from Princeton University's Department of Astrophysical Sciences. The final speaker, Dr. Linda Schale is a cosmologist from the University of Texas at Austin. She was said to be a 'paleontologist of the human mind' who tries 'to understand mechanisms people use to understand the world'. The concluding discussion centered on why NASA scientists don t communicate better with people who are not highly educated. This is a big concern because to continue its work, NASA needs to communicate the importance of its goals to the average person. Additional information is included in the original extended abstract.

    An in vitro evaluation of the anti-microbial activity of medicated soaps was conducted using ditch-plate and hand washing techniques. Strains of reference microbes namely Candida albicans (ATCC90028), Staphylococcus aureus (ATCC25923), Pseudomonas aureginosa (ATCC27853) and Escherichia coli (ATCC25922) were tested at three different soaps' concentrations (1.0, 4.0 and 8.0 mg/ml). A total of 16 medicated soaps were assayed for their antimicrobial efficacy. Of these, 13 were medicated and 3 non-medicated soaps, which served as control. Ciprofloxacin and ketaconazole were employed as positive controls. Label disclosure for the soaps' ingredients and other relevant information were absorbed. The most common antimicrobial active ingredients were triclosan, trichloroxylenol and trichlorocarbanilide. ANOVA for means of zones of inhibition revealed variability of antimicrobial activity among the medicated soaps. Positive correlation (r=0.318; P<0.01) between zones of inhibition and soaps' concentrations was evidenced. Hand washing frequencies positively correlated with microbial counts. Roberts(®) soap exhibited the largest zone of inhibition (34 mm) on S. aureus. Candida albicans was the least susceptible microbe. Regency(®) and Dalan(®) exhibited the least zone of inhibition on the tested bacteria. Protex(®), Roberts(®), Family(®) and Protector(®) were equally effective (P<0.01) against S. aureus. In conclusion, majority of the assayed medicated soaps have satisfactory antibacterial activity; though lack antifungal effect with exception of Linda(®) liquid soap. The hand washing technique has proved to be inappropriate for evaluation of soaps' antimicrobial efficacy due to presence of the skin microflora. PMID:22131630

    Henrietta Mercer, the senior vice president for human resources at LaSalle Chemical, is facing a challenge unprecedented in her career: Steve Ambler, recently appointed the company's group sales director, has decided to change his gender identity. Before Henrietta can finish crafting a corporate response, someone slips a copy of her confidential memo to the executive committee to one of Steve's colleagues, whose outraged reaction suggests the difficulties that may lie ahead. How can she help him transition in a workplace where not everyone is on board with the plan? Linda E. Taylor, the director of work life, equity, and inclusion at Raytheon Missile Systems, advises Henrietta to offer lots of gender identity training. When Raytheon employees question the morality of condoning transgender choices, she replies that the company doesn't pass judgment on its employees' private lives and that working for Raytheon means adhering to its policy of inclusion. Ronald K. Andrews, a vice president and head of human resources at Prudential, says it is crucial to work very closely with the person transitioning and points out that the individual's courage may be what most strikes colleagues. Prudential held a meeting to educate account executives and provide them with talking points before they spoke directly to key clients - not one of whom was lost. Stasha Goliaszewski, a scientist and engineer at Boeing, started her gender transition after four years with the company. HR support helped with other employees, and her professional expertise helped when she called on customers. She advises large companies to prepare their gender-identity policies and not be caught off guard, as Henrietta was. Statistics show that, sooner or later, they are bound to encounter the issue.

  11. Ring Around a Galaxy

    NASA Technical Reports Server (NTRS)

    1999-01-01

    Space Telescope Science Institute astronomers are giving the public chances to decide where to aim NASA's Hubble Space Telescope. Guided by 8,000 Internet voters, Hubble has already been used to take a close-up, multi-color picture of the most popular object from a list of candidates, the extraordinary 'polar-ring' galaxy NGC 4650A. Located about 130 million light-years away, NGC 4650A is one of only 100 known polar-ring galaxies. Their unusual disk-ring structure is not yet understood fully. One possibility is that polar rings are the remnants of colossal collisions between two galaxies sometime in the distant past, probably at least 1 billion years ago. What is left of one galaxy has become the rotating inner disk of old red stars in the center. Meanwhile, another smaller galaxy which ventured too close was probably severely damaged or destroyed. The bright bluish clumps, which are especially prominent in the outer parts of the ring, are regions containing luminous young stars, examples of stellar rebirth from the remnants of an ancient galactic disaster. The polar ring appears to be highly distorted. No regular spiral pattern stands out in the main part of the ring, and the presence of young stars below the main ring on one side and above on the other shows that the ring is warped and does not lie in one plane. Determining the typical ages of the stars in the polar ring is an initial goal of our Polar Ring Science Team that can provide a clue to the evolution of this unusual galaxy. The HST exposures were acquired by the Hubble Heritage Team, consisting of Keith Noll, Howard Bond, Carol Christian, Jayanne English, Lisa Frattare, Forrest Hamilton, Anne Kinney and Zolt Levay, and guest collaborators Jay Gallagher (University of Wisconsin-Madison), Lynn Matthews (National Radio Astronomy Observatory-Charlottesville), and Linda Sparke (University of Wisconsin-Madison).

    Background & Objectives: As more heart transplant recipients survive into late adolescence, research addressing long-term psychosocial and neurodevelopmental outcomes is imperative. The limited literature available suggests risk for psychosocial difficulties and lower cognitive, academic, and neuropsychological functioning. This paper reviews topic-related literature and provides preliminary data examining psychosocial and neuropsychological functioning of adolescents who received their heart transplant during infancy. Method: This paper offers a literature review AND presents preliminary data from studies conducted through Loma Linda University Children’s Hospital (LLUCH). Study one examined psychosocial functioning and quality of life of adolescent infant heart transplant recipients. In study two, cognitive, academic, and neuropsychological data were analyzed. Results: Study 1: Overall psychosocial functioning fell in the Average range, however, a significant percentage of participants presented with difficulties on one or more of the psychosocial domains. Quality of life was also within normal limits, though concerns with general health and bodily discomfort were noted. Study 2: Cognitive functioning was assessed to be Below Average, with 43-62% of the participants demonstrating significant impairments. Neuropsychological functioning yielded significant weakness on language functioning, and mild weakness on visual-motor integration and executive functioning. Conclusion: While the majority of the participants demonstrate psychosocial resiliency, a subgroup present with difficulties suggesting the need for intervention. Cognitive/neuropsychological functioning suggests poorer functioning with patterns similar to other high-risk pediatric populations. These results are preliminary and further research on long-term psychosocial and neuropsychological development of pediatric heart transplant recipients is needed to better understand and ameliorate developmental

    On December 2, 2015, a terror attack in the city of San Bernardino, California killed 14 Americans and injured 22 in the deadliest attack on U.S. soil since September 11, 2001. Although emergency personnel and law enforcement officials frequently deal with multi-casualty incidents (MCIs), what occurred that day required an unprecedented response. Most of the severely injured victims were transported to either Loma Linda University Medical Center (LLUMC) or Arrowhead Regional Medical Center (ARMC). These two hospitals operate two designated trauma centers in the region and played crucial roles during the massive response that followed this attack. In an effort to shed a light on our response to others, we provide an account of how these two teaching hospitals prepared for and coordinated the medical care of these victims. In general, both centers were able to quickly mobilize large number of staff and resources. Prior disaster drills proved to be invaluable. Both centers witnessed excellent teamwork and coordination involving first responders, law enforcement, administration, and medical personnel from multiple specialty services. Those of us working that day felt safe and protected. Although we did identify areas we could have improved upon, including patchy communication and crowd-control, they were minor in nature and did not affect patient care. MCIs pose major challenges to emergency departments and trauma centers across the country. Responding to such incidents requires an ever-evolving approach as no two incidents will present exactly alike. It is our hope that this article will foster discussion and lead to improvements in management of future MCIs. PMID:26823922

    The space radiation environment poses risks to astronaut health from a diverse set of sources, ranging from low-energy protons and electrons to highly-charged, high-energy atomic nuclei and their associated fragmentation products, including neutrons. The low-energy protons and electrons are the source of most of the radiation dose to Shuttle and ISS crews, while the more energetic particles that comprise the Galactic Cosmic Radiation (protons, He, and heavier nuclei up to Fe) will be the dominant source for crews on long-duration missions outside the earth's magnetic field. Because of this diversity of sources, a broad ground-based experimental effort is required to validate the transport and shielding calculations used to predict doses and dose-equivalents under various mission scenarios. The experimental program of the LBNL group, described here, focuses principally on measurements of charged particle and neutron production in high-energy heavy-ion fragmentation. Other aspects of the program include measurements of the shielding provided by candidate spacesuit materials against low-energy protons (particularly relevant to extra-vehicular activities in low-earth orbit), and the depth-dose relations in tissue for higher-energy protons. The heavy-ion experiments are performed at the Brookhaven National Laboratory's Alternating Gradient Synchrotron and the Heavy-Ion Medical Accelerator in Chiba in Japan. Proton experiments are performed at the Lawrence Berkeley National Laboratory's 88'' Cyclotron with a 55 MeV beam, and at the Loma Linda University Proton Facility with 100 to 250 MeV beam energies. The experimental results are an important component of the overall shielding program, as they allow for simple, well-controlled tests of the models developed to handle the more complex radiation environment in space.

    Energetic protons, neutrons, and heavy ions undergoing collisions with target nuclei of varying Z can produce residual heavy recoil fragments via intra-nuclear cascade/evaporation reactions. The particles produced in these non-elastic collisions generally have such extremely short range ({approx}<10 {mu}m) that they cannot be directly observed by conventional detection methods including CR-39 plastic nuclear track detector (PNTD) that has been chemically etched for analysis by standard visible light microscopy. However, high-LET recoil fragments having range on the order of several cell diameters can be produced in tissue during radiotherapy using proton and carbon beams. We have developed a method to analyze short-range, high-LET tracks in CR-39 plastic nuclear track detector (PNTD) using short duration chemical etching ({approx}<1 {mu}m) following by automated atomic force microscope (AFM) scanning. The post-scan data processing used in this work was based on semi-automated matrix analysis opposed to traditional grey-scale image analysis. This method takes advantage of the 3-D data obtained via AFM to achieve robust discrimination of nuclear tracks from other features inherently present in the post-etch detector surface. Through automation of AFM scanning, sufficient AFM scan frames were obtained to attain an LET spectrum spanning the LET range from 200-1500 keV/{mu}m. In addition to our experiments, simulations were carried out with the Monte Carlo transport code, FLUKA. To demonstrate this method, CR-39 PNTD was exposed to the proton therapy beam at Loma Linda University Medical Center (LLUMC) at 60 and 230 MeV. Additionally, detectors were exposed to 1 GeV protons at the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL). For these exposures CR-39 PNTD, Al and Cu target foils were used between detector layers.

    Future space missions will involve long-term travel beyond the magnetic field of the Earth, where astronauts will be exposed to radiation hazards such as those that arise from galactic cosmic rays. Galactic cosmic rays are composed of protons, alpha particles, and particles of high energy and charge (HZE particles). Research by our group has shown that exposure to HZE particles, primarily 600 MeV/n and 1 GeV/n 56Fe, can produce significant alterations in brain neurochemistry and behavior. However, given that protons can make up a significant portion of the radiation spectrum, it is important to study their effects on neural functioning and on related performance. Therefore, these studies examined the effects of exposure to proton irradiation on neurochemical and behavioral endpoints, including dopaminergic functioning, amphetamine-induced conditioned taste aversion learning, and spatial learning and memory as measured by the Morris water maze. Male Sprague-Dawley rats received a dose of 0, 1.5, 3.0 or 4.0 Gy of 250 MeV protons at Loma Linda University and were tested in the different behavioral tests at various times following exposure. Results showed that there was no effect of proton irradiation at any dose on any of the endpoints measured. Therefore, there is a contrast between the insignificant effects of high dose proton exposure and the dramatic effectiveness of low dose (<0.1 Gy) exposures to 56Fe particles on both neurochemical and behavioral endpoints.

These two hospitals operate two designated trauma centers in the region and played crucial roles during the massive response that followed this attack. In an effort to shed a light on our response to others, we provide an account of how these two teaching hospitals prepared for and coordinated the medical care of these victims. In general, both centers were able to quickly mobilize large number of staff and resources. Prior disaster drills proved to be invaluable. Both centers witnessed excellent teamwork and coordination involving first responders, law enforcement, administration, and medical personnel from multiple specialty services. Those of us working that day felt safe and protected. Although we did identify areas we could have improved upon, including patchy communication and crowd-control, they were minor in nature and did not affect patient care. MCIs pose major challenges to emergency departments and trauma centers across the country. Responding to such incidents requires an ever-evolving approach as no two incidents will present exactly alike. It is our hope that this article will foster discussion and lead to improvements in management of future MCIs.

    Purpose: To report a case-matched analysis comparing high-dose external-beam radiation (EBRT) for prostate cancer delivered on Proton Radiation Oncology Group (PROG) 95-09, a randomized trial, with permanent prostate brachytherapy over the same era. Methods: From 1996 to 1999, 196 patients were accrued to the high-dose arm (79.2 Gray equivalent (GyE) using photons and protons) of PROG 95-09 at the Massachusetts General Hospital and Loma Linda University Medical Center. Entry criteria specified T1-2 and prostate-specific antigen {<=}15 ng/mL. When Gleason score >7 was excluded, 177 men were left for case matching. At Massachusetts General Hospital, 203 similar patients were treated by a single brachytherapist from 1997 to 2002. Minimum follow-up was 3 years. Case matching, based on T stage, Gleason score, prostate-specific antigen, and age resulted in 141 matches (282 patients). Median follow-up was 8.6 and 7.4 years for EBRT and brachytherapy, respectively. The primary endpoint was biochemical failure (BF). Results: Using the Phoenix definition, the 8-year BF rates were 7.7% and 16.1% for EBRT and brachytherapy, respectively (p = 0.42). A stratified analysis was performed by risk group. In the EBRT group, 113 and 28 patients were low and intermediate risk, respectively. In the brachytherapy group, 118 and 23 were. When stratified by risk group, the BF rates were similar by either technique. Conclusions: High-dose EBRT and brachytherapy result in similar BF rates for men with localized prostate cancer. Comparative quality-of-life and cost-effectiveness studies are warranted.

    Background. There are places around the world where people live longer and they are active past the age of 100 years, sharing common behavioral characteristics; these places (i.e., Sardinia in Italy, Okinawa in Japan, Loma Linda in California and Nicoya Peninsula in Costa Rica) have been named the "Blue Zones". Recently it was reported that people in Ikaria Island, Greece, have also one of the highest life expectancies in the world, and joined the "Blue Zones". The aim of this work work was to evaluate various demographic, lifestyle and psychological characteristics of very old (>80 years) people participated in Ikaria Study. Methods. During 2009, 1420 people (aged 30+) men and women from Ikaria Island, Greece, were voluntarily enrolled in the study. For this work, 89 males and 98 females over the age of 80 yrs were studied (13% of the sample). Socio-demographic, clinical, psychological and lifestyle characteristics were assessed using standard questionnaires and procedures. Results. A large proportion of the Ikaria Study's sample was over the age of 80; moreover, the percent of people over 90 were much higher than the European population average. The majority of the oldest old participants reported daily physical activities, healthy eating habits, avoidance of smoking, frequent socializing, mid-day naps and extremely low rates of depression. Conclusion. Modifiable risk factors, such as physical activity, diet, smoking cessation and mid-day naps, might depict the "secrets" of the long-livers; these findings suggest that the interaction of environmental, behavioral together with clinical characteristics may determine longevity. This concept must be further explored in order to understand how these factors relate and which are the most important in shaping prolonged life.

  9. How we built a strong company in a weak industry.

    When Roger Brown and Linda Mason decided to start a child care and early-education company 15 years ago, they knew about the challenges inherent in the industry: no barriers to entry, low margins, few economies of scale, heavy regulatory oversight--to name just a few. But that didn't stop them. They eventually built Bright Horizons Family Solutions, a company that now has more than 340 high-quality child care centers, serving 40,000 children and employing 12,000 people. How did they do it? Sheer determination helped. But even more important, they developed a business model that took advantage of industry weaknesses. When the couple sat down to hash out a plan for the company, they realized that the key to achieving profitability and creating barriers to entry was to partner with companies. They could achieve higher returns by having those companies build and outfit the centers and, at the same time, boost customer loyalty. Indeed, Bright Horizon's corporate clients came to see the state-of-the-art centers as a way to distinguish themselves in the eyes of current and prospective employees. The high-quality child care attracted the best employees and raised retention rates. Brown's first-person account describes the difficulties the couple and their company faced along the way, including the struggle for funding and a board that questioned Bright Horizons' business model and basic philosophy of good child care. But, Brown says, the commitment to a singular business model and the determination to make strengths out of weaknesses made the impossible possible.

    Determination of the Bragg peak position in proton therapy requires accurate knowledge of the electron density and ratio of effective atomic number and mass (Z/A) of the body tissues traversed. While the Z/A ratio is fairly constant for human tissues, the density of tissues varies significantly. One possibility to obtain accurate electron density information of tissues is to use protons of sufficient energy to penetrate the patient and measure their energy loss. From these transmission measurements, it is possible to reconstruct a three-dimensional map of electron densities using algebraic techniques. The interest in proton computed tomography (pCT) has considerably increased in recent years due to the more common use of proton accelerators for cancer treatment world-wide and a modern design concept based on current high-energy physics technology has been suggested. This contribution gives a status update on the pCT project carried out by the pCT Collaboration, a group of institutions sharing interest and expertise in the development of pCT. We will present updated imaging data obtained with a small pCT prototype developed in collaboration with the Santa Cruz Institute of Particle Physics and installed on the proton research beam line at Loma Linda University Medical Center. We will discuss hardware decisions regarding the next-generation pCT scanner, which will permit scanning of head-sized objects. Progress has also been made in the formulation of the most likely path of protons through an object and parallelizable iterative reconstruction algorithms that can be implemented on general-purpose commodity graphics processing units. Finally, we will present simulation studies for utilizing pCT technology for on-line proton dose verification and tumor imaging with positron emission tomography (PET)

  11. Tharsis: Consequence of Mars' Dichotomy and Layered Mantle

    The two largest and most striking features on Mars are the crustal dichotomy, the nearly hemispheric division in topography, gravity, crustal thickness, and age, and Tharsis, a volcanic center active from the Noachian to the present. Tharsis' long-term persistence of localized volcanism is, to the best of our knowledge, unique in the solar system. Explaining the timing of Tharsis volcanism, from initiation early in martian history to recent activity, has been an enduring challenge. Here we present an model of the martian mantle that can explain early and persistent volcanism at Tharsis by incorporating the effects of the crustal dichotomy and a compositionally layered mantle. As the crust is expected to be enriched in heat-producing elements, this dichotomy in thickness leads to a dichotomous heat flux boundary condition on the mantle, which affects the internal dynamics. The evidence for layering includes the ability of a layered mantle to simultaneously meet a chondritic bulk composition and the moment-of-inertia factor (Elkins-Tanton et al., in revision), which can not be done with a one-layered mantle. In addition, studies of the martian meteorites suggest that the martian mantle is heterogeneous, a constraint that can be met with layering. We perform analog laboratory experiments with corn syrup to simulate Mars' thermal evolution. We vary the presence of a partial insulating lid, to simulate the effect of the dichotomy, and layering in the convecting fluid. We show that in the case of a layered mantle and an insulating lid, a large swell, which acts to localize upwelling plumes under the lid, forms early and endures for the scaled equivalent of billions of years.

    Linda Pineda1Ana Christina Ravelo2Ivano Aiello3Zach Stewart2Wilson Sauthoff2 Earth and Planetary Sciences Department, UCSC Ocean Sciences Department, UCSC Moss Landing Marine Lab Natural climate change affects coastal water resources, human land use, and marine biological productivity. In particular, the seasonal migration of the Intertropical Convergence Zone (ITCZ) is influenced by changes in global-scale temperature and pressure gradients and is responsible for spatial changes in summertime rainfall in Mesoamerica impacting regional water resources and the strength of upwelling. In October 2014, aboard the Research Vessel El Puma, a 3.9 meter long core (G14-P12) was recovered from the Northeast flank of the Guaymas Basin in the Gulf of California within the oxygen minimum zone (27˚52.11'N, 111˚41.51'W, water depth of 677m) to investigate changes in seasonal upwelling and Central Mexico rainfall over the last ~1000 years. The age model was developed using Pb210, C14 and lamination counting. The time interval includes the Little Ice Age and the Medieval Warm Period. Biological productivity and precipitation proxy records were produced using an X-Ray Fluorescence (XRF) core-scanner and a color line scanner to generate a record of bulk chemistry and color reflectance. The records indicate marked decadal and centennial scale variability in the lithologic composition of the sediment superimposed on millimeter-scale variability that reflects the presence of seasonally laminated sediments. Nitrogen isotopic and nitrogen weight % measurements were used, in combination with the scanned data, to interpret changes in nitrate utilization and biological productivity. These new records will have broad implications on the link between regional coastal environmental conditions in the Gulf of California and global climate change.

  13. A Primordial and Complicated Ocean of Magma on Mars

    It seems almost certain that the Moon was surrounded by an ocean of magma when it formed. This important idea has been applied to the other terrestrial planets and even to asteroids. Linda (Lindy) Elkins-Tanton and colleagues Mark Parmentier, Paul Hess, and Sarah Zaranek at Brown University, and Lars Borg and David Draper (University of New Mexico) have examined the chemical and physical consequences of magma ocean crystallization on Mars. Elkins-Tanton has focused on the fate of the pile of crystals created during solidification of a magma ocean over a thousand kilometers thick. Crystallization causes the minerals that form first to lie beneath those formed later. The deepest minerals are also less dense than the overlying minerals. This is an unstable situation: the low-density rocks would have a tendency to rise while the high-density rocks would have a tendency to sink. Although we think of rocks as solid and hard, when hot and under pressure, they flow like liquids. They do not flow fast, but they do flow like ultra-gooey liquids (about a factor of 100 million billion times gooier than ketchup at room temperature). Thus, the heavy layers sink and the light layers rise, producing a complicated Martian mantle with chemical characteristics like those cosmochemists infer from studies of Martian meteorites. The sinking of relatively cool rocks from the top of the crystallized pile cools the boundary between the metallic core and the mantle, causing motions inside the core to produce the early, strong magnetic field of Mars.

    Energetic protons, neutrons, and heavy ions undergoing collisions with target nuclei of varying Z can produce residual heavy recoil fragments via intra-nuclear cascade/evaporation reactions. The particles produced in these non-elastic collisions generally have such extremely short range ({approx}< 10 {mu}m) that they cannot be directly observed by conventional detection methods including CR-39 plastic nuclear track detector (PNTD) that has been chemically etched for analysis by standard visible light microscopy. However, high-LET recoil fragments having range on the order of several cell diameters can be produced in tissue during radiotherapy using proton and carbon beams. We have developed a method to analyze short-range, high-LET tracks in CR-39 plastic nuclear track detector (PNTD) using short duration chemical etching ({approx}< 1 {mu}m) followed by automated atomic force microscope (AFM) scanning. The post-scan data processing used in this work was based on semi-automated matrix analysis opposed to traditional grey-scale image analysis. This method takes advantage of the 3-D data obtained via AFM to achieve robust discrimination of nuclear tracks from other features. Through automation of AFM scanning, sufficient AFM scan frames were obtained to attain an LET spectrum spanning the LET range from 200-1500 keV/{mu}m. In addition to our experiments, simulations were carried out with the Monte Carlo transport code, FLUKA. To demonstrate this method, CR-39 PNTD was exposed to the proton therapy beam at Loma Linda University Medical Center (LLUMC) at 60 and 230 MeV. Additionally, detectors were exposed to I GeV protons at the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL). For these exposures CR-39 PNTD, Al and Cu target foils were used between detector layers.

    Chlorine is recognized and commonly used biocide for power plant cooling water and service water treatment programs, including the control of zebra mussels. Chlorine dioxide has recently become a popular method of zebra mussel control because of its economy, safety, environmental acceptability, and effectiveness when compared to other mussel control methods. This control technique was recently demonstrated at Dairyland Power Cooperative`s Alma Generating Station on the east bank of the upper Mississippi River in Alma, Wisconsin. The project was assisted with EPRI Tailored Collaboration Program funds. The Dairyland Power Alam Generating Station consists of five generating units that utilize raw, untreated Mississippi River water for condenser, circulating, and service water supplies. The first units were built in 1947, with the final and largest unit being completed in 1960. Total station generating capacity is 200 MW. Because of recent increases in the zebra mussel density at the station intake, Dairyland Power selected the team of Nalco and Rio Linda to perform a chlorine dioxide treatment of the station`s new water systems to eradicate and control the mussels before their presence created operational difficulties. This paper will present the results of the treatment including treatment theory, design and construction of the treatment system, the method of chlorine dioxide generation, treatment concentration, analytical methods o monitoring chlorine dioxide generation, residuals and trihalomethane (THM) concentrations, protocol for monitoring treatment mortality, and the effects of chlorine dioxide and detoxification on other water chemistry parameters and equipment materials. The goal of this paper is to inform and assist users with establishing consistent and uniform practices for safely utilizing and monitoring chlorine dioxide in the eradication and control of zebra mussels.

    Henrietta Mercer, the senior vice president for human resources at LaSalle Chemical, is facing a challenge unprecedented in her career: Steve Ambler, recently appointed the company's group sales director, has decided to change his gender identity. Before Henrietta can finish crafting a corporate response, someone slips a copy of her confidential memo to the executive committee to one of Steve's colleagues, whose outraged reaction suggests the difficulties that may lie ahead. How can she help him transition in a workplace where not everyone is on board with the plan? Linda E. Taylor, the director of work life, equity, and inclusion at Raytheon Missile Systems, advises Henrietta to offer lots of gender identity training. When Raytheon employees question the morality of condoning transgender choices, she replies that the company doesn't pass judgment on its employees' private lives and that working for Raytheon means adhering to its policy of inclusion. Ronald K. Andrews, a vice president and head of human resources at Prudential, says it is crucial to work very closely with the person transitioning and points out that the individual's courage may be what most strikes colleagues. Prudential held a meeting to educate account executives and provide them with talking points before they spoke directly to key clients - not one of whom was lost. Stasha Goliaszewski, a scientist and engineer at Boeing, started her gender transition after four years with the company. HR support helped with other employees, and her professional expertise helped when she called on customers. She advises large companies to prepare their gender-identity policies and not be caught off guard, as Henrietta was. Statistics show that, sooner or later, they are bound to encounter the issue.

    Between 2004 and 2006 the Loma Linda University ESSE21 Mesoamerican Project (Earth System Science Education for the 21st Century) collaborated with a series of academic, NGO (nongovernmental) and government agencies, including a USAID (United States Agency for International Development) integrated environmental resource management project to: a) build the human and technical capacity of local partners in the use of geospatial technologies, e.g. GIS, GPS, Remote Sensing, b) improve their capacity to apply these tools to biodiversity, health, sustainability, protected-area management, and other NRM (Natural Resource Management) decision-making needs and problems, and c) establish long term institutional relationships for teacher/student exchange, including development of joint curricula and research projects focused on health geoinformatics as well as sustainable development. Much of this has contributed toward a new "geotourism" effort adopted by Honduras called the SAVE Honduras strategy (Scientific, Academic, Volunteer, Educational).

  1. Tissue equivalent proportional counter microdosimetry measurements utililzed aboard aircraft and in accelerator based space radiation shielding studies

    NASA Astrophysics Data System (ADS)

    Gersey, Brad; Wilkins, Richard

    The space radiation environment presents a potential hazard to the humans, electronics and materials that are exposed to it. Particle accelerator facilities such as the NASA Space Ra-diation Laboratory (NSRL) and Loma Linda University Medical Center (LLUMC) provide particle radiation of specie and energy within the range of that found in the space radiation environment. Experiments performed at these facilities determine various endpoints for bio-logical, electronic and materials exposures. A critical factor in the performance of rigorous scientific studies of this type is accurate dosimetric measurements of the exposures. A Tissue Equivalent Proportional Counter (TEPC) is a microdosimeter that may be used to measure absorbed dose, average quality factor (Q) and dose equivalent of the particle beam utilized in these experiments. In this work, results from a variety of space radiation shielding studies where a TEPC was used to perform dosimetry in the particle beam will be presented. These results compare the absorbed dose and dose equivalent measured downstream of equal density thicknesses of stan-dard and multifunctional shielding materials. The standard materials chosen for these shielding studies included High-Density Polyethylene (HDPE) and aluminum alloy, while the multifunc-tional materials included carbon composite infused with single walled carbon nanotubes. High energy particles including proton, silicon and iron nuclei were chosen as the incident radia-tion for these studies. Further, TEPC results from measurements taken during flights aboard ER-2 and KC-135 aircraft will also be discussed. Results from these flight studies include TEPC measurements for shielded and unshielded conditions as well as the effect of vibration and electromagnetic exposures on the TEPC operation. The data selected for presentation will highlight the utility of the TEPC in space radiation studies, and in shielding studies in particular. The lineal energy response function of the

  3. Space radiation shielding studies for astronaut and electronic component risk assessment

    NASA Astrophysics Data System (ADS)

    Fuchs, Jordan; Gersey, Brad; Wilkins, Richard

    The space radiation environment is comprised of a complex and variable mix of high energy charged particles, gamma rays and other exotic species. Elements of this radiation field may also interact with intervening matter (such as a spaceship wall) and create secondary radiation particles such as neutrons. Some of the components of the space radiation environment are highly penetrating and can cause adverse effects in humans and electronic components aboard spacecraft. Developing and testing materials capable of providing effective shielding against the space radiation environment presents special challenges to researchers. Researchers at the Cen-ter for Radiation Engineering and Science for Space Exploration (CRESSE) at Prairie View AM University (PVAMU) perform accelerator based experiments testing the effectiveness of various materials for use as space radiation shields. These experiments take place at the NASA Space Radiation Laboratory at Brookhaven National Laboratory, the proton synchrotron at Loma Linda University Medical Center, and the Los Alamos Neutron Science Center at Los Alamos National Laboratory where charged particles and neutrons are produced at energies similar to those found in the space radiation environment. The work presented in this paper constitutes the beginning phase of an undergraduate research project created to contribute to this ongoing space radiation shielding project. Specifically, this student project entails devel-oping and maintaining a database of information concerning the historical data from shielding experiments along with a systematic categorization and storage system for the actual shielding materials. The shielding materials referred to here range in composition from standard materi-als such as high density polyethylene and aluminum to exotic multifunctional materials such as spectra-fiber infused composites. The categorization process for each material includes deter-mination of the density thickness of individual

    The Proceedings As co-chairs of the 9th International Symposium on Display Holography, we welcome readers of this collection of papers and posters presented at the event. We hope that both attendees of the event and others pursuing the art, science, and business of holography and 3D imaging will find the authors' contributions of lasting interest and importance. The Event Since its creation at Lake Forest College in 1982 by Professor Tung H Jeong, ISDH has followed a model that differentiates it from other scientific conferences. The 9th ISDH continued this history, fully occupying a floor of the MIT Media Lab for five days. The single-track conference opened with reports on the state of holography in the various nations represented by the attendees, followed by a series of presentations on Education and Holography. One and one-half days of papers on Art and Holography followed, then sessions on Techniques and Materials, Digital Techniques, and Commercial and Applied Holography. A poster session permitted more in-depth discussion between authors and the audience. Two exhibitions of holographic works opened at ISDH: an informal display area at the symposium, and a 15-month-long MIT Museum exhibition, The Jeweled Net: Views of Contemporary Holography. The success of an event of this sort requires the help of many people and organizations. We wish especially to recognize our Honorary Conference Chairs: Tung H Jeong and Joseph W Goodman; our Technical Program Committee: Hans I Bjelkhagen, Frank Fan, Nasser Peyghambarian, and Hiroshi Yoshikawa; and our Arts and Exhibition Committee: Betsy Connors-Chen, Melissa Crenshaw, John Durant, Dieter Jung, Linda Law, Martin Richardson, Jonathan Ross, and Sally Weber. Betsy also coordinated the on-site exhibition. Kristin Hall at the MIT Media Lab made local arrangements, while registration was handled by MIT Conference Services.

    The FOX project, funded under the ASCR X-stack I program, developed systems software and runtime libraries for a new approach to the data and work distribution for massively parallel, fault oblivious application execution. Our work was motivated by the premise that exascale computing systems will provide a thousand-fold increase in parallelism and a proportional increase in failure rate relative to today’s machines. To deliver the capability of exascale hardware, the systems software must provide the infrastructure to support existing applications while simultaneously enabling efficient execution of new programming models that naturally express dynamic, adaptive, irregular computation; coupled simulations; and massive data analysis in a highly unreliable hardware environment with billions of threads of execution. Our OS research has prototyped new methods to provide efficient resource sharing, synchronization, and protection in a many-core compute node. We have experimented with alternative task/dataflow programming models and shown scalability in some cases to hundreds of thousands of cores. Much of our software is in active development through open source projects. Concepts from FOX are being pursued in next generation exascale operating systems. Our OS work focused on adaptive, application tailored OS services optimized for multi → many core processors. We developed a new operating system NIX that supports role-based allocation of cores to processes which was released to open source. We contributed to the IBM FusedOS project, which promoted the concept of latency-optimized and throughput-optimized cores. We built a task queue library based on distributed, fault tolerant key-value store and identified scaling issues. A second fault tolerant task parallel library was developed, based on the Linda tuple space model, that used low level interconnect primitives for optimized communication. We designed fault tolerance mechanisms for task parallel computations

  7. Development of a responsive and constructivist portfolio-based assessment of a writing-to-learn curriculum in introductory astronomy: A case study

    NASA Astrophysics Data System (ADS)

    French, Mary

    As the primary evaluator of a National Science Foundation grant-supported project to develop an introductory, writing-to-learn-based astronomy curriculum, my goal was to help design and test materials that would meet the learning needs of non-science majors, especially women and minorities, and promote their science literacy. My immediate problem was to create a context-sensitive assessment that engages teachers' goals and objectives while reconciling these with the diverse needs, interests, and abilities of students. To that end, I developed a responsive or stakeholder-focused constructivist assessment based upon Guba and Lincoln's fourth generation evaluation. Both responsive and constructivist, my-approach reflects recent developments in sociocognitive theories of writing and learning, especially those by Linda Flower. Flower focuses on the literate act or learning task, such as writing a summary, as the basic unit of analysis. Not the act itself but the "site" at which it occurs is of main interest. This is where the tension between the private "self" and the public "other" provides an opportunity for meaning to evolve as students explore alternate writing and learning strategies through inner acts of negotiation. Because the new astronomy curriculum centered around students keeping a learning log or process portfolio, portfolios afforded the ideal documentary evidence of the site at which students negotiate meanings and strategies. The portfolio-based assessment, therefore, centers upon having evaluators or teacher-researchers identify and interpret how students represent learning tasks to themselves and develop strategies to complete these tasks. Researchers next compare and judge their own interpretations of these behaviors according to the pre-ordinate objectives of the curriculum. Then the key stakeholders (i.e., evaluators, students, and teachers), through hermeneutic and dialectic interchanges, reconstruct or recondition these pre-ordmate evaluation

  9. Atomic force microscopy methods for the analysis of high-LET tracks in CR-39 plastic nuclear track detector

    NASA Astrophysics Data System (ADS)

    Johnson, Carl E., Jr.

    Scope and Method of Study. Proton- and neutron-induced target fragmentation reactions generate short-range (˜1-10 mum), high-linear energy transfer (LET) heavy nuclear recoil (HNR) particles that contribute to total radiation dose deposited in healthy tissue in patients undergoing proton cancer therapy and to astronauts during spaceflight. Conventional detection using CR-39 plastic nuclear track detector (PNTD) that has been chemically etched for analysis by standard visible light microscopy fails because the required bulk etch, B ≈ 40 mum removes short-range tracks. We have developed a method based on Atomic Force Microscopy (AFM) to directly measure HNR particle tracks in CR-39 PNTD. Novel algorithms using least squares ellipse fitting and estimation of fitting in an iterative process were developed to enable the analysis of nuclear tracks in AFM data. In irradiations conducted at the Loma Linda University Medical Center (LLUMC) Proton Therapy Facility and the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL), targets of varying composition, including a number of elemental targets of high Z, were exposed in contact with layers of CR-39 PNTD to beams of 60 MeV, 230 MeV, and 1 GeV protons at doses between 2 and 10 Gy. Chemical etching of the CR-39 PNTD was performed under standard conditions (50°C, 6.25 N NaOH) for 2-4 hours (removed layer B = 0.5-1.0 mum). Findings and Conclusions. The use of a short duration chemical etch yielded densities of secondary tracks of 105-10 6 cm-2 using the analysis methods presented in this work for accelerator-based experiments. LET spectra were obtained with good statistics between 200 and 1500 keV/mum and the results were consistent with nonelastic nuclear cross sections. Absorbed dose measurements were also completed for selected detectors, ˜7 x 10-10 Gy ion -1 was measured for 230 MeV protons. Additionally our data are consistent with an isotropic HNR particle production mechanism. The semi

The abuse of prescription drugs is facilitated by easy access (via physicians, the Internet, and the medicine cabinet) and a perception of safety (since the drugs are FDA approved). In addition to the personal toll of drug abuse using prescription drugs, indirect costs associated with prescription drug abuse and diversion include product theft, commission of other crimes to support addiction, law enforcement costs, and encouraging the practice of defensive medicine." The Administration witnesses, Bertha Madras, Nora D. Volkow, MD, Sandra Kweder, MD, and Joe Rannazzisi reviewed the problem of drug abuse and discussed what is being done at the present time as well as future strategies to combat drug abuse, including prescription drug monitoring programs, reducing malprescriptions, public education, eliminating Internet drug pharmacies, and the development of future drugs which are not only tamper-resistant but also non-addictive. The second panel, consisting of consumers and advocates, included Misty Fetco, Linda Surks, and Barbara van Rooyan, all of whom lost their children to drugs, presented their stories and strategies to prevent drug abuse, focusing on education at all levels, development of resistant drugs, and non-opioid treatment of chronic pain.

  11. The Venus "Shell-over-Star" hieroglyph and Maya warfare: An examination of the interpretation of a Mayan symbol

    NASA Astrophysics Data System (ADS)

    Voit, Claudia Ann

    For decades, Maya scholars have associated the Mayan "Shell-Star" (also referred to as "Star-War") hieroglyph with Maya warfare. Put forward by scholars such as Floyd Lounsbury and David Kelley, and later advanced by Linda Schele, David Freidel, Ian Graham, Peter Matthews, Anthony Aveni and others, there are now dozens of published articles and chapters relating the hieroglyph to Venus and warfare. Venus is one of the most notable celestial objects outside of the Sun and Moon and was highly visible to the inhabitants of the Maya world. The Dresden Codex (an astronomical almanac) contains important information about the planet Venus, and the calendar section was deciphered by the librarian and mathematician, Ernst Förstemann in the late 1800s. In his decipherment, he deduced that the numbers contained in the tables must be connected to the orbital period of the planet. There is no other planet with the same orbital period 3 as Venus. Förstemann suggested that the decoded astronomy tables were used by the Maya to determine when to wage war. This interpretation, along with others, like Floyd Lounsbury`s study of Venus and the Long Count date at Bonampak were the seeds that have led to methodological errors that first began to take root in Maya research. The idea of the Venus association with warfare took hold and continues to propagate. Many scholars continue to assert that the "shell-star" glyph is related to warfare events. Others, like Gerardo Aldana, and Stanley Guenter, have recently come forward to reexamine and question the hieroglyph and its relationship, if any, to Maya warfare. I suggest, further, that methodological errors may have occurred along the way. I propose that these errors include data lost in translation, and inaccurate translations. In addition, the statistical analysis of Venus cycles has weak points. If this identification of the errors is correct, we need to re-evaluate the weakened foundation on which we are building our assertions about

    Now that no more observations are being added to my catalog of four-color photometry, corrections have been made by comparing the magnitudes of some of the brighter standard stars from night to night and bringing them to a common zeropoint. The table in the poster paper presents the final, corrected, four-color indices for two sets of stars. The first set contains those standard stars which have been observed ten or more times. The range in the number of observations is from 10 to 139, with an average of 34. The probable errors of the catalog observations for the standard stars are ± 0.003, 0.007, 0.005 and the probable errors relative to the published values of the standards (Crawford & Barnes 1970 AJ 73, 978) are ± 0.002, 0.004, 0.004 in (b-y), c1 and m1, respectively. The second set contains secondary standards. Again the number of observations starts at 10 and runs up to 168 with an average of 41. The probable errors of the observations are ± 0.005, 0.010, 0.008 and the probable errors relative to the stars listed in Hauck & Mermilliod (A&AS 129, 431) are ± 0.003, 0.004, 0.007 in (b-y), c1 and m1. The secondary standards range in magnitude y from 5.09 to 10.82. The stars are well spaced in right ascension in both the northern and southern hemispheres. About a dozen of the secondary standard stars are field horizontal-branch stars. The observations were made over a period of 21 years with 41 runs at KPNO, 24 at CTIO, 3 at Mount Wilson, 2 at Steward Observatory and 1 at ESO. A number of people participated in some of these observations and I would like to acknowledge Donald Hayes, John Drilling, Saul Adelman, Larry Relyea, Linda Tifft Matlock and Pascal Dubois for their help. The observatories listed above a thanked for assigning the observing time. Part of this work was supported by grants from the National Science Foundation.

    Background: Fertility plays an important role in sexual and psychological function in families. Infertility can result in major emotional, social, and mental disorders, including a reduction in satisfaction with marital life and quality of life. The present study aimed to compare the quality of life and marital satisfaction and sexual satisfaction between fertile and infertile couples. Materials and Methods: This analytical cross-sectional study was conducted on 250 couples at the Fatemiyeh Educational Research Center affiliated to Hamadan University of Medical Sciences, Hamadan, Iran, from May to August in 2014. The subjects were randomly selected from the patients referred to this center using a table of random numbers. They were then allocated into two groups of infertile group (n=125) and fertile group (n=125). The study participants completed World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, Linda Berg’s Sexual Satisfaction Scale, and Enrich Marital Satisfaction Scale. Then, the data were entered into the SPSS version16 for statistical analysis. The Chi-square and Mann-Whitney tests were also applied to compare the data between the groups. Results: The results revealed no significant difference between the two groups regarding demographic and general health variables. The mean scores of sexual satisfaction were 63.67 ± 13.13 and 46.37 ± 7.72 in the fertile and infertile couples, respectively. Furthermore, the mean scores of marital satisfaction were also 44.03 ± 9.36 and 36.20 ± 4.03 in the fertile and infertile groups, respectively. Our finding demonstrated that the fertile couples obtained significantly higher mean scores of quality of life as well as lower mean scores of sexual satisfaction and marital satisfaction as compared to the infertile ones (P<0.001). Conclusion: According to the results, the fertile couples obtained significantly higher quality of life and lower sexual satisfaction and marital satisfaction as

    2011-01-01

    Space radiation is a complex mixed field of ionizing radiation that can pose hazardous risks to sophisticated electronics and humans. Mission planning for lunar exploration and long duration habitat construction will face tremendous challenges of shielding against various types of space radiation in an attempt to minimize the detrimental effects it may have on materials, electronics, and humans. In late 2009, the Lunar Crater Observation and Sensing Satellite (LCROSS) discovered that water content in lunar regolith found in certain areas on the moon can be up to 5.6 +/-2.8 weight percent (wt%) [A. Colaprete, et. al., Science, Vol. 330, 463 (2010). ]. In this work, shielding studies were performed utilizing ultra high molecular weight polyethylene (UHMWPE) and aluminum, both being standard space shielding materials, simulated lunar regolith/ polyethylene composites, and simulated lunar regolith mixed with UHMWPE particles and water. Based on the LCROSS findings, radiation shielding experiments were conducted to test for shielding efficiency of regolith/UHMWPE/water mixtures with various percentages of water to compare relative shielding characteristics of these materials. One set of radiation studies were performed using the proton synchrotron at the Loma Linda Medical University where high energy protons similar to those found on the surface of the moon can be generated. A similar experimental protocol was also used at a high energy spalation neutron source at Los Alamos Neutron Science Center (LANSCE). These experiments studied the shielding efficiency against secondary neutrons, another major component of space radiation field. In both the proton and neutron studies, shielding efficiency was determined by utilizing a tissue equivalent proportional counter (TEPC) behind various thicknesses of shielding composite panels or mixture materials. Preliminary results from these studies indicated that adding 2 wt% water to regolith particles could increase shielding of

Lantagne, Linda M. Abriola and Kurt D. Pennell* Detailed knowledge of the processes governing nanoparticle transport and reactivity in porous media is essential for accurate predictions of environmental fate, water and wastewater treatment system performance, and assessment of potential risks to ecosystems and water supplies. To address these issues, an interdisciplinary research team combined experimental and mathematical modeling studies to investigate the mobility, dissolution, and aging of silver nanoparticles (nAg) in representative aquifer materials and ceramic filters. Results of one-dimensional column studies, conducted with water-saturated sands maintained at pH 4 or 7 and three levels of dissolved oxygen (DO), revealed that fraction of silver mass eluted as Ag+ increased with increasing DO level, and that the dissolution of attached nAg decreased over time as a result of surface oxidation. A hybrid Eulerain-Lagragian nanoparticle transport model, which incorporates DO-dependent dissolution kinetics and particle aging, was able to accurately simulate nAg mobility and Ag+ release measured in the column experiments. Model sensitivity analysis indicated that as the flow velocity and particle size decrease, nAg dissolution and Ag+ transport processes increasingly govern silver mobility. Consistent results were obtained in studies of ceramic water filters treated with nAg, where silver elution was shown to be governed by nAg dissolution to form Ag+ and subsequent cation exchange reactions. Recent studies explored the effects of surface coating aging on nAg aggregation, mobility and dissolution. Following ultraviolet light, nAg retention in water saturated sand increased by 25-50%, while up to 50% of the applied mass eluted as Ag+ compared to less than 1% for un-aged n

    The NW-SE trending southern California coastline between the Palos Verdes Peninsula and San Diego roughly parallels the southern part and off-shore extension of the dominantly right-lateral, strike-slip, Newport-Inglewood fault zone. Emergent marine terraces between Newport Bay and San Diego record general uplift and gentle warping on the northeast side of the fault zone throughout Pleistocene time. Marine terraces on Soledad Mt. and Point Loma record local differential uplift (maximum 0.17 m/ka) during middle to late Pleistocene time on the southwest side of the fault (Rose Canyon fault) near San Diego. The broad Linda Vista Mesa (elev. 70-120 m) in the central part of coastal San Diego County, previously thought to be a single, relatively undeformed marine terrace of Plio-Pleistocene age, is a series of marine terraces and associated beach ridges most likely formed during sea-level highstands throughout Pleistocene time. The elevations of the terraces in this sequence gradually increase northwestward to the vicinity of San Onofre, indicating minor differential uplift along the central and northern San Diego coast during Pleistocene time. The highest, oldest terraces in the sequence are obliterated by erosional dissection to the northwest where uplift is greatest. Broad, closely spaced (vertically) terraces with extensive beach ridges were the dominant Pleistocene coastal landforms in central San Diego County where the coastal slope is less than 1% and uplift is lowest. The beach ridges die out to the northwest as the broad low terraces grade laterally into narrower, higher, and more widely spaced (vertically) terraces on the high bluffs above San Onofre where the coastal slope is 20-30% and uplift is greatest. At San Onofre the terraces slope progressively more steeply toward the ocean with increasing elevation, indicating continuous southwest tilt accompanying uplift from middle to late Pleistocene time. This southwest tilt is also recorded in the asymmetrical

    Background: Fertility plays an important role in sexual and psychological function in families. Infertility can result in major emotional, social, and mental disorders, including a reduction in satisfaction with marital life and quality of life. The present study aimed to compare the quality of life and marital satisfaction and sexual satisfaction between fertile and infertile couples. Materials and Methods: This analytical cross-sectional study was conducted on 250 couples at the Fatemiyeh Educational Research Center affiliated to Hamadan University of Medical Sciences, Hamadan, Iran, from May to August in 2014. The subjects were randomly selected from the patients referred to this center using a table of random numbers. They were then allocated into two groups of infertile group (n=125) and fertile group (n=125). The study participants completed World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, Linda Berg’s Sexual Satisfaction Scale, and Enrich Marital Satisfaction Scale. Then, the data were entered into the SPSS version16 for statistical analysis. The Chi-square and Mann-Whitney tests were also applied to compare the data between the groups. Results: The results revealed no significant difference between the two groups regarding demographic and general health variables. The mean scores of sexual satisfaction were 63.67 ± 13.13 and 46.37 ± 7.72 in the fertile and infertile couples, respectively. Furthermore, the mean scores of marital satisfaction were also 44.03 ± 9.36 and 36.20 ± 4.03 in the fertile and infertile groups, respectively. Our finding demonstrated that the fertile couples obtained significantly higher mean scores of quality of life as well as lower mean scores of sexual satisfaction and marital satisfaction as compared to the infertile ones (P<0.001). Conclusion: According to the results, the fertile couples obtained significantly higher quality of life and lower sexual satisfaction and marital satisfaction as

    In 2006 the Loma Linda University ESSE21 Mesoamerican Project (Earth System Science Education for the 21st Century) along with partners such as the University of Redlands and California State University, Pomona, produced an online learning module that is designed to help students learn critical remote sensing skills-- specifically: ecosystem characterization, i.e. doing a supervised or unsupervised classification of satellite imagery in a tropical coastal environment. And, it would teach how to measure land use / land cover change (LULC) over time and then encourage students to use that data to assess the Human Dimensions of Global Change (HDGC). Specific objectives include: 1. Learn where to find remote sensing data and practice downloading, pre-processing, and "cleaning" the data for image analysis. 2. Use Leica-Geosystems ERDAS Imagine or IDRISI Kilimanjaro to analyze and display the data. 3. Do an unsupervised classification of a LANDSAT image of a protected area in Honduras, i.e. Cuero y Salado, Pico Bonito, or Isla del Tigre. 4. Virtually participate in a ground-validation exercise that would allow one to re-classify the image into a supervised classification using the FAO Global Land Cover Network (GLCN) classification system. 5. Learn more about each protected area's landscape, history, livelihood patterns and "sustainability" issues via virtual online tours that provide ground and space photos of different sites. This will help students in identifying potential "training sites" for doing a supervised classification. 6. Study other global, US, Canadian, and European land use/land cover classification systems and compare their advantages and disadvantages over the FAO/GLCN system. 7. Learn to appreciate the advantages and disadvantages of existing LULC classification schemes and adapt them to local-level user needs. 8. Carry out a change detection exercise that shows how land use and/or land cover has changed over time for the protected area of your choice

    We examined the ability of two transcutaneous devices (Fastrac, Sensormedics Corporation, Yorba Linda, California, U.S.A. and Hewlett Packard M1018A, Hewlett Packard Component Monitoring System, Hewlett Packard, North Hollywood, U.S.A.) to measure arterial PCO2 and PO2 in neonates. Thirty-seven neonates had transcutaneous oxygen measured with the Hewlett Packard (HPO2 group), 38 neonates had transcutaneous carbon dioxide measured with the Hewlett Packard (HPCO2 group) and the Fastrac was used on 27 neonates (FTCO2 group). Both devices were operated with electrode temperatures of 43.5 degrees C although an additional ten subjects were studied using the Fastrac with an electrode temperature of 43.0 degrees C. The mean differences (transcutaneous--arterial) and upper and lower limits of agreement were calculated for each group. For the HPO2 group they were 3.78 mmHg (-12.23 to 19.80 mmHg), for the HPCO2 group they were 0.40 mmHg (-4.50 to 5.30 mmHg) and for the FTCO2 they were -0.96 mmHg (-7.85 to 5.92 mmHg). For the Fastrac group at an electrode temperature of 43.0 degrees C the mean difference and limits of agreement were -1.00 mmHg and -4.58 mmHg to 2.58 mmHg. The average sensitivity and specificity for both machines for the detection of hypocarbia were 82% and 92% respectively while for hypercarbia they were 90% and 94% respectively. For hypoxaemia, the sensitivity and specificity were 40% and 94% while for hyperoxaemia the sensitivity and specificity were 83% and 97%. We conclude that both machines provide a useful supplement to arterial PCO2 measurements and the Fastrac performs better at 43.0 degrees C. The measurement of PO2 is less accurate but is still of clinical use.

    The risks to personnel in space from the naturally occurring radiations are generally considered to be one of the most serious limitations to human space missions, as noted in two recent reports of the National Research Council/National Academy of Sciences. The Core Project of the Radiation Effects Team for the National Space Biomedical Research Institute is the consequences of radiations in space in order to develop countermeasure, both physical and pharmaceutical, to reduce the risks of cancer and other diseases associated with such exposures. During interplanetary missions, personnel in space will be exposed to galactic cosmic rays, including high-energy protons and energetic ions with atomic masses of iron or higher. In addition, solar events will produce radiation fields of high intensity for short but irregular durations. The level of intensity of these radiations is considerably higher than that on Earth's surface, and the biological risks to astronauts is consequently increased, including increased risks of carcinogenesis and other diseases. This group is examining the risk of cancers resulting from low-dose, low-dose rate exposures of model systems to photons, protons, and iron by using ground-based accelerators which are capable of producing beams of protons, iron, and other heavy ions at energies comparable to those encountered in space. They have begun the first series of experiments using a 1-GeV iron beam at the Brookhaven National Laboratory and 250-MeV protons at Loma Linda University Medical Center's proton synchrotron facility. As part of these studies, this group will be investigating the potential for the pharmaceutical, Tamoxifen, to reduce the risk of breast cancer in astronauts exposed to the level of doses and particle types expected in space. Theoretical studies are being carried out in a collaboration between scientists at NASA's Johnson Space Center and Johns Hopkins University in parallel with the experimental program have provided

    The Center for Radiation Engineering and Science for Space Exploration (CRESSE) at Prairie View A&M University, Prairie View, Texas, USA, is establishing an integrated, multi-disciplinary research program on the scientific and engineering challenges faced by NASA and the international space community caused by space radiation. CRESSE focuses on space radiation research directly applicable to astronaut health and safety during future long term, deep space missions, including Martian, lunar, and other planetary body missions beyond low earth orbit. The research approach will consist of experimental and theoretical radiation modeling studies utilizing particle accelerator facilities including: 1. NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory; 2. Proton Synchrotron at Loma Linda University Medical Center; and 3. Los Alamos Neutron Science Center (LANSCE) at Los Alamos National Laboratory. Specifically, CRESSE investigators are designing, developing, and building experimental test beds that simulate the lunar and Martian radiation environments for experiments focused on risk assessment for astronauts and instrumentation. The testbeds have been designated the Bioastronautics Experimental Research Testbeds for Environmental Radiation Nostrum Investigations and Education (BERT and ERNIE). The designs of BERT and ERNIE will allow for a high degree of flexibility and adaptability to modify experimental configurations to simulate planetary surface environments, planetary habitats, and spacecraft interiors. In the nominal configuration, BERT and ERIE will consist of a set of experimental zones that will simulate the planetary atmosphere (Solid CO2 in the case of the Martian surface.), the planetary surface, and sub-surface regions. These experimental zones can be used for dosimetry, shielding, biological, and electronic effects radiation studies in support of space exploration missions.

    organization, and physiological balances. Using microgravity simulated in the clinostats, it is possible to investigate the effects of this factor on the relationships in the system “virus - host plant”. This problem remains important as its solution allows to discover a wider set of techniques allowing to obtain plants free from viral infections. The possibility of the WSMV (wheat steak mosaic virus) elimination in wheat plants under the influence of simulated microgravity has been demonstrated in our works. The study of this phenomenon allowed to admit that the freeing of plants from viral infection under the impact of simulated microgravity occurs in the process of induced resistance formation. In our further research activities, we used potato plants for which the elimination of viral infections is of exceptional importance. Viruses transmitted mechanically have to use a vascular system to move all over the plant and, finally, into the tubers. The factors limiting this movability will at certain moments of plant growth favor the elimination of virus in certain parts of the plant. Introduction of tissues from such parts into in vitro cultures allows to regenerate virus-free plants. Еру efficiency of tissue culture in combination with clonal micro multiplication in vitro allows to obtain up to 1 mln plants from a single one in half a year. Such a productivity of a new technology allowed to prognosticate the potato production in vitro in the world on the level of 212 mln plantlets per year. But today, according to some estimates the in vitro potato production may be achieved with lower expenditures on plant remediation and freeing of the cultivars from viral infection. Therefore the purpose of work was to probe possibilities of receiving virus free seminal material of potato at the terms of clinorotation and set of its economic efficiency.

    Cerasela Zoica Dinu, Effects of acid treatment on structure, properties and biocompatibility of carbon nanotubes, Applied Surface Science, 2013, 268, 261-268.) Chapter two shows how exposure to CNTs changes the biomechanical properties of fixed human lung epithelial cells (BEAS-2B cells). Specifically, by using Atomic Force Microscopy (AFM) nanoindentation technology, we demonstrated that cellular exposure to multi-walled carbon nanotubes (MWCNTs) for 24h induces significant changes in cellular biomechanics leading to increased cellular stiffness. The MWCNTs incubation also seemed to alter the surface area of the cells. Consequently, measures of the mechanical properties of the exposed cell could be used as indicators of its biological state and could offer valuable insights into the mechanisms associated with CNTs-induced genetic instability. (Publication: Chenbo Dong, Linda Sargent, Michael L Kashon, David Lowry, Jonathan S. Dordick, Steven H. Reynolds, Yon Rojanasakul and Cerasela Zoica Dinu, Expose to carbon nanotubes leads to change in cellular biomechanics, Advanced Healthcare Materials, 2013, 7, 945-951.) Chapter three links together the MWCNTs exposure duration, internalization and induced biomechanical changes in fixed cells. Our findings indicated that changes in biomechanical properties of the fixed cells are a function of the uptake and internalization of the MWCNTs as well as their uptake time. Specifically, short exposure time did not seem to lead to considerable changes in the elastic properties in the cellular system. However, longer cellular exposure to CNTs leads to a higher uptake and internalization of the nanotubes and a larger effect on the cell mechanics. Such changes could be related to CNTs interactions with cellular elements and could bring information on the CNT intrinsic toxicity. Chapter four talks about the potential of purified forms of CNTs with increased hydrophilicity to affect live human lung epithelial cells when used at occupational

There has been a great initiative by their health center to focus prevention efforts on incoming freshman". HBCU administrations must bear in mind that beyond the campus, students will undoubtedly carry the information learned during college into the communities in which they live after graduation and moreover, utilize this information as a basis for educating their children and families. Community activist and Columbia resident Linda "T'Zima" Brown, whose 16 year-old son is considering application to Delaware State University, believes that HBCUs bear a great responsibility to the well-being of the community, "We as residents should be able to take part in the events that our black colleges have. Black colleges used to operate from a more inclusive, family approach, and we need to get back to that; plus, many HBCUs are supported with our state dollars, so the community should be able to look to them for information aside from what our children relay to us".

For solving the close approach problem the trajectories of launch vehicle and the payload upon injection have been generated at short intervals within the total launch window so as to account for the short duration of the conjunctions. SPADEPRO analysis has been carried out for Two Line Element (TLE) set of objects with different epoch dates leading to the actual day of launch so as to determine the sensitivity of blackout period with regards to epoch of space objects TLE sets. Authors have developed SPADEPRO analysis package described above, consisting of modules which provide the respective functions of (1) ephemeris generation and reconstruction of primary object (launch vehicle or its payload upon insertion), (2) determination of close approaches with resident space objects, (3) computation of the covariance of the primary and the secondary objects to represent the knowledge uncertainty (resident space objects) and (4) computation of the collision risk given the covariance. This has been successfully applied to PSLV-C3 launch in October 2001.

    chert deposition, as well as the onset of the oceanic anoxic event itself, is related to eccentricity maxima. The stable 405-kyr periodicity of eccentricity is readily discernible in the data records and can be used for tuning to the astronomical solution (Laskar et al. 2011). A total of five and a half 405-kyr cycles can be identified below the Bonarelli level, which itself comprises a 405-kyr cycle. This cyclostratigraphy can potentially be anchored to the absolute time scale by using the newly determined Cenomanian-Turonian boundary age of 93.9 ± 0.15 Ma, which is based on intercalibration of astrochronological and radioisotopic data for the Cenomanian-Turonian boundary interval near the GSSP in Colorado, USA (Meyers et al., 2012). Correlation to the orbitally tuned Turonian interval of the nearby Gubbio and Contessa sections in Italy (De Vleeschouwer et al., this session) allows the construction of an anchored astronomical time scale for the Cenomanian-Turonian interval of > 5 Ma.

This approach also makes apparent significant EVA gaps, for example, the U.S. gap between 1985 and 1991 following the Challenger accident. This NASA History Monograph is an edited extract from an extensive EVA Chronology and Reference Book being produced by the EVA Project Office, NASA Johnson Space Center, Houston, Texas. The larger work will be published as part of the NASA Formal Series in 1998.

    are used to identify the first two pairs of horizontal vibrational frequencies, which are then used to compute the response on every floor of the building, constrained by the observed data. The approach has been applied to a CSN-instrumented 12-story reinforced concrete building near downtown Los Angeles. The frequencies were identified directly from spectra of the 8 August 2012 M4.5 Yorba Linda, California earthquake acceleration time series. When the basic dimensions and the first two frequencies are input into a prismatic Timoshenko beam model of the building, the model yields mode shapes that have been shown to match well with densely recorded data. For the instrumented 12-story building, comparisons of the predictions of responses on other floors using only the record from the 9th floor with actual data from the other floors shows this method to approximate the true response remarkably well.

    readings are recorded. Well No.5 had been determined to have a faulty drain valve while trying to operate the pump for emergency water usage. It was determined that water was not able to drain and began to flow out from the test hole (TH9). Charlie and Simon pumped out the remaining water from the test hole prior to replacing the valve. The valve was subsequently dug up, replaced and tested for operation. SAFETY AND TRAINING: The winter season has approached and conditions can be hazardous as Cle Elum staff stress safety while working and preparing acclimation sites for upcoming fish transfer. Some examples include wearing proper clothing, extra caution while driving and plowing snow. GROUNDS: Linda Lamebull of fisheries and personnel from Tribal Purchasing came to the hatchery to inventory two way radios.

    photons. Over the course of this research, tissues other than spleens were archived and with funding obtained from other sources, including the Department of Radiation Medicine at the Loma Linda University Medical Center, some additional assays were performed. Furthermore, groups of additional mice were included that were pre-exposed to low-dose photons before irradiating with acute photons, protons, and simulated solar particle event (SPE) protons. Hence, the original support together with the additional funding for our research led to generation of much valuable information that was originally not anticipated. Some of the data has already resulted in published articles, manuscripts in review, and a number of presentations at scientific conferences and workshops. Difficulties in reliable and reproducible quantification of secreted cytokines using multi-plex technology delayed completion of this study for a period of time. However, final analyses of the remaining data are currently being performed and should result in additional publications and presentations in the near future. Some of the most notable conclusions, thus far, are briefly summarized below: - Distribution of leukocytes were dependent upon cell type, radiation quality, body compartment analyzed, and time after exposure. Low-dose protons tended to have less effect on numbers of major leukocyte populations and T cell subsets compared to low-dose photons. - The patterns of gene and cytokine expression in CD4+ T cells after protracted low-dose irradiation were significantly modified and highly dependent upon the total dose and time after exposure. - Patterns of gene and cytokine expression differed substantially among groups exposed to low-dose photons versus low-dose protons; differences were also noted among groups exposed to much higher doses of photons, protons, and simulated SPE protons. - Some measurements indicated that exposure to low-dose photon radiation, especially 0.01 Gy, significantly
