Employing Machine-Learning Methods to Study Young Stellar Objects

NASA Astrophysics Data System (ADS)

Moore, Nicholas

2018-01-01

Vast amounts of data exist in the astronomical data archives, and yet a large number of sources remain unclassified. We developed a multi-wavelength pipeline to classify infrared sources. The pipeline uses supervised machine learning methods to classify objects into the appropriate categories. The program is fed data that is already classified to train it, and is then applied to unknown catalogues. The primary use for such a pipeline is the rapid classification and cataloging of data that would take a much longer time to classify otherwise. While our primary goal is to study young stellar objects (YSOs), the applications extend beyond the scope of this project. We present preliminary results from our analysis and discuss future applications.

2015-01-01

Summer training in aging research for medical students is a strategy for improving the pipeline of medical students into research careers in aging and clinical care of older adults. Johns Hopkins University has been offering medical students a summer experience of mentored research, research training, and clinical shadowing since 1994. Long-term outcomes of this program have not been described. The authors surveyed all 191 participants who had been in the program from 1994-2010 (60% female and 27% underrepresented minorities) and received a 65.8% (N = 125) response rate. The authors also conducted Google and other online searches to supplement study findings. Thirty-seven percent of those who have completed training are now in academic medicine, and program participants have authored or coauthored 582 manuscripts. Among survey respondents, 95.1% reported that participation in the Medical Student Training in Aging Research program increased their sensitivity to the needs of older adults. This program may help to build commitment among medical students to choose careers in aging.

Mentoring is a critical aspect of research and training; and the adoption of a successful mentoring model for guiding researchers through the educational pipeline is lacking. The Continuing Umbrella of Research Experiences (CURE) program was established in the Comprehensive Minority Biomedical Branch; which is part of the National Cancer Institute. This program offers unique training and career development opportunities to enhance diversity in cancer research. The CURE initiative focuses on broadening the cadre of underserved investigators engaging in cancer research. CURE begins with high school students and fosters scientific, academic and research excellence throughout the trainee's educational progression. The program supports students throughout the entirety of their training career. During this period, the trainee matures into a competitive early stage investigator; capable of securing advanced research project funding in academic and industry workforces. Thus, the CURE program provides a comprehensive vehicle for training and reinforces the critical mass of underserved investigators conducting cancer research.

Increasing participation by historically underrepresented Americans in the STEM workforce remains a national priority. Existing strategies have failed to increase diversity especially in the physical sciences despite federal mandates. To meet this urgent challenge, it is imperative to immediately identify and support the expansion of effective high school-to-college STEM pipelines. A Bridge to the Stars (ABttS) is a creative and tested pipeline designed to steadily increase the numbers of disadvantaged 15-21 year-olds pursuing and completing 4-year STEM degrees. This unique program offers extended engagement in astronomy, arguably the most accessible window to science, through a 3-tier STEM immersion program of innovative learning (in a freshman science course), authentic research training (in a freshman science lab), and supportive near-peer mentoring at U.Missouri-Kansas City, an urban research university. Each tier of the ABttS pipeline by itself has the potential to broaden student aspirations for careers as technological innovators or STEM educators. Students who elect to transition through multiple tiers will substantially reinforce their successes with STEM activities, and significantly bolster their self-esteem necessary to personally manifest STEM aspirations. We will summarize the impact of this program after 5 years, and share our latest improvements. The long-term mission of ABttS is to see urban educational institutions across the U.S. adopt similar pipelines in all STEM disciplines built on the ABttS model.

Implementing a Workforce Development Pipeline

NASA Technical Reports Server (NTRS)

Hix, Billy

2002-01-01

Research shows that the number of highly trained scientists and engineers has continued a steady decline during the 1990's. Furthermore, at the high school level, almost 40% of the total high school graduates are seeking technical skills in preparation of entering the workforce directly. The decrease of students in technology and science programs, along with the lack of viable vocational programs, haunts educators and businesses alike. However, MSFC (Marshall Space Flight Center) has the opportunity to become a leading edge model of workforce development by offering a unified program of apprenticeships, workshops, and educational initiatives. These programs will be designed to encourage young people of all backgrounds to pursue the fields of technology and science, to assist research opportunities, and to support teachers in the systemic changes that they are facing. The emphasis of our program based on grade levels will be: Elementary Level: Exposure to the workforce. Middle School: Examine the workforce. High School and beyond: Instruct the workforce. It is proposed that MSFC create a well-integrated Workforce Development Pipeline Program. The program will act to integrate the many and varied programs offered across MSFC directorates and offices. It will offer a clear path of programs for students throughout middle school, high school, technical training, and college and universities. The end result would consist of technicians, bachelors degrees, masters degrees, and PhDs in science and engineering fields entering the nation's workforce, with a focus on NASA's future personnel needs.

Regionalisation of general practice training--are we meeting the needs of rural Australia?

Campbell, David G; Greacen, Jane H; Giddings, Patrick H; Skinner, Lesley P

2011-06-06

The concept of "social accountability" has underpinned the development of many medical education programs over the past decade. Success of the regionalisation of the general practice training program in Australia will ultimately be measured by the ability of the program to deliver a sufficient rural general practice workforce to meet the health needs of rural communities. Regionalisation of general practice training in Australia arose from the 1998 recommendations of the Ministerial Review of General Practice Training. The resultant competitive structure adopted by government was not the preferred option of the Review Committee, and may be a negative influence on rural workforce, as the competitive corporate structure of regional training providers has created barriers to meaningful vertical integration. Available data suggest that the regionalised training program is not yet providing a sustainable general practice workforce to rural Australia. The current increase in medical student and general practice training places provides an opportunity to address some of these issues. In particular, it is recommended that changes be made to registrar selection processes, the rural pipeline and vertical integration of training, and training for procedural rural practice. To achieve these goals, perhaps it is time for another comprehensive ministerial review of general practice training in Australia.

The Preparing Academically Successful Students in Maternal and Child Health (MCH PASS) training program provided financial support and specialized training to occupational therapy (OT) and speech-language pathology (SLP) undergraduate students from underrepresented groups in maternal and child health. The project assisted undergraduate trainees to matriculate into graduate programs in their respective fields and facilitated application into long-term maternal and child health training programs. Sixteen trainees (8 OT and 8 SLP) participated in an undergraduate training program with an emphasis on interdisciplinary teaming, family mentoring, leadership development, public health and population-based research. Instruction occurred in community and classroom settings through didactic instruction and small group discussions. Fifteen of the trainees applied to and were accepted in graduate programs in their respective fields. Two trainees applied to a long-term MCH training program. Students reported increased knowledge about programs that serve women and children, the effects of poverty on health, interdisciplinary teaming and the daily routines of families who have a child with a special health care need. The MCH PASS program provided a unique opportunity for undergraduate students in OT and SLP to learn about public health with an emphasis on maternal and child health. The specialized preparation enabled students to understand better the health concerns of underserved families whose children have special health care needs.

2011-01-01

Today's doctoral programs continue to prepare students for a traditional academic career path despite the inadequate supply of research-focused faculty positions. We advocate for a broader doctoral curriculum that prepares trainees for a wide range of science-related career paths. In support of this argument, we describe data from our survey of doctoral students in the basic biomedical sciences at University of California, San Francisco (UCSF). Midway through graduate training, UCSF students are already considering a broad range of career options, with one-third intending to pursue a non–research career path. To better support this branching career pipeline, we recommend that national standards for training and mentoring include emphasis on career planning and professional skills development to ensure the success of PhD-level scientists as they contribute to a broadly defined global scientific enterprise.

Purpose Clinician-scientists are considered an endangered species for many reasons, including challenges with establishing and maintaining a career pipeline. Career outcomes from year-long medical and dental students’ research enrichment programs have not been well determined. Therefore, the authors assessed career and research outcome data from a cohort of participants in the National Institutes of Health (NIH) Clinical Research Training Program (CRTP). Method The CRTP provided a year-long mentored clinical or translational research opportunity for 340 medical and dental students. Of these, 135 completed their training, including fellowships, from 1997 to January 2014. Data for 130 of 135 were analyzed, including time conducting research, types of public funding (NIH grants), and publications from self-reported surveys that were verified via NIH RePORT and PUBMED. Results Nearly two-thirds (84 of 130) indicated that they were conducting research, and over half of the 84 (approximately one-third of the total cohort) spent more than 25% of time devoted to research. Of those 84, over 25% received grant support from the NIH, and those further in their careers published more scholarly manuscripts. Conclusions Data suggest that the CRTP helped foster the careers of research-oriented medical and dental students as measured by time conducting research, successful competition for federal funding, and the publication of their research. Longer follow-up is warranted to assess the impact of these mentored research experiences. Investments in mentored research programs for health professional students are invaluable to support the dwindling pipeline of biomedical researchers and clinician-scientists. PMID:27224296

2010-12-01

Increased focus on the number and type of physicians delivering health care in the United States necessitates a better understanding of changes in graduate medical education (GME). Data collected by the Accreditation Council for Graduate Medical Education (ACGME) allow longitudinal tracking of residents, revealing the number and type of residents who continue GME following completion of an initial residency. We examined trends in the percent of graduates pursuing additional clinical education following graduation from ACGME-accredited pipeline specialty programs (specialties leading to initial board certification). Using data collected annually by the ACGME, we tracked residents graduating from ACGME-accredited pipeline specialty programs between academic year (AY) 2002-2003 and AY 2006-2007 and those pursuing additional ACGME-accredited training within 2 years. We examined changes in the number of graduates and the percent of graduates continuing GME by specialty, by type of medical school, and overall. The number of pipeline specialty graduates increased by 1171 (5.3%) between AY 2002-2003 and AY 2006-2007. During the same period, the number of graduates pursuing additional GME increased by 1059 (16.7%). The overall rate of continuing GME increased each year, from 28.5% (6331/22229) in AY 2002-2003 to 31.6% (7390/23400) in AY 2006-2007. Rates differed by specialty and for US medical school graduates (26.4% [3896/14752] in AY 2002-2003 to 31.6% [4718/14941] in AY 2006-2007) versus international medical graduates (35.2% [2118/6023] to 33.8% [2246/6647]). The number of graduates and the rate of continuing GME increased from AY 2002-2003 to AY 2006-2007. Our findings show a recent increase in the rate of continued training for US medical school graduates compared to international medical graduates. Our results differ from previously reported rates of subspecialization in the literature. Tracking individual residents through residency and fellowship programs provides a better understanding of residents' pathways to practice.

Purpose To assist in determining barriers to an oncology career incorporating cancer prevention, the American Society of Clinical Oncology (ASCO) Cancer Prevention Workforce Pipeline Work Group sponsored surveys of training program directors and oncology fellows. Methods Separate surveys with parallel questions were administered to training program directors at their fall 2013 retreat and to oncology fellows as part of their February 2014 in-training examination survey. Forty-seven (67%) of 70 training directors and 1,306 (80%) of 1,634 oncology fellows taking the in-training examination survey answered questions. Results Training directors estimated that ≤ 10% of fellows starting an academic career or entering private practice would have a career focus in cancer prevention. Only 15% of fellows indicated they would likely be interested in cancer prevention as a career focus, although only 12% thought prevention was unimportant relative to treatment. Top fellow-listed barriers to an academic career were difficulty in obtaining funding and lower compensation. Additional barriers to an academic career with a prevention focus included unclear career model, lack of clinical mentors, lack of clinical training opportunities, and concerns about reimbursement. Conclusion Reluctance to incorporate cancer prevention into an oncology career seems to stem from lack of mentors and exposure during training, unclear career path, and uncertainty regarding reimbursement. Suggested approaches to begin to remedy this problem include: 1) more ASCO-led and other prevention educational resources for fellows, training directors, and practicing oncologists; 2) an increase in funded training and clinical research opportunities, including reintroduction of the R25T award; 3) an increase in the prevention content of accrediting examinations for clinical oncologists; and 4) interaction with policymakers to broaden the scope and depth of reimbursement for prevention counseling and intervention services.

2018-01-01

Pathological evaluation of tumor tissue is pivotal for diagnosis in cancer patients and automated image analysis approaches have great potential to increase precision of diagnosis and help reduce human error. In this study, we utilize several computational methods based on convolutional neural networks (CNN) and build a stand-alone pipeline to effectively classify different histopathology images across different types of cancer. In particular, we demonstrate the utility of our pipeline to discriminate between two subtypes of lung cancer, four biomarkers of bladder cancer, and five biomarkers of breast cancer. In addition, we apply our pipeline to discriminate among four immunohistochemistry (IHC) staining scores of bladder and breast cancers. Our classification pipeline includes a basic CNN architecture, Google's Inceptions with three training strategies, and an ensemble of two state-of-the-art algorithms, Inception and ResNet. Training strategies include training the last layer of Google's Inceptions, training the network from scratch, and fine-tunning the parameters for our data using two pre-trained version of Google's Inception architectures, Inception-V1 and Inception-V3. We demonstrate the power of deep learning approaches for identifying cancer subtypes, and the robustness of Google's Inceptions even in presence of extensive tumor heterogeneity. On average, our pipeline achieved accuracies of 100%, 92%, 95%, and 69% for discrimination of various cancer tissues, subtypes, biomarkers, and scores, respectively.

For more than 40 years, there has been a concerted national effort to promote diversity among the scientific research community. Yet given the persistent national-level disparity in educational achievements of students from various ethnic and racial groups, the efficacy of these programs has come into question. The current study reports results from a longitudinal study of students supported by a national National Institutes of Health–funded minority training program, and a propensity score matched control. Growth curve analyses using Hierarchical Linear Modeling show that students supported by Research Initiative for Science Excellence were more likely to persist in their intentions to pursue a scientific research career. In addition, growth curve analyses indicate that undergraduate research experience, but not having a mentor, predicted student persistence in science. PMID:24285910

Boulay, Rachel; van Raalte, Lisa

2014-01-01

Commitment to the STEM (science, technology, engineering, math) pipeline is slowly declining despite the need for professionals in the medical field. Addressing this, the John A. Burns School of Medicine developed a summer teacher-training program with a supplemental technology-learning component to improve science teachers' knowledge and skills of Molecular Biology. Subsequently, students' skills, techniques, and application of molecular biology are impacted. Science teachers require training that will prepare them for educating future professionals and foster interest in the medical field. After participation in the program and full access to the virtual material, twelve high school science teachers completed a final written reflective statement to evaluate their experiences. Using thematic analysis, knowledge and classroom application were investigated in this study. Results were two-fold: teachers identified difference areas of gained knowledge from the teacher-training program and teachers' reporting various benefits in relation to curricula development after participating in the program. It is concluded that participation in the program and access to the virtual material will impact the science community by updating teacher knowledge and positively influencing students' experience with science.

Pootakham, Thanyakarn; Kumar, Amit

2010-09-01

Bio-oil, produced by fast pyrolysis of biomass, has high energy density compared to 'as received' biomass. The study assesses and compares the cost of transportation ($/liter of bio-oil) of bio-oil by pipeline and truck. The fixed and variable cost components of transportation of bio-oil at a pipeline capacity of 560 m(3)/day and to a distance of 100 km are 0.0423$/m(3) and 0.1201$/m(3)/km, respectively. Pipeline transportation of bio-oil costs less than transportation by liquid tank truck (load capacity 30 m(3)) and super B-train trailer (load capacity 60 m(3)) above pipeline capacities of 1000 and 1700 m(3)/day, respectively. When transportation distance is greater than 100 km, bio-oil must be heated at booster stations. When transporting bio-oil by pipeline to a distance of 400 km, minimum pipeline capacities of 1150 and 2000 m(3)/day are required to compete economically with liquid tank trucks and super B-train tank trailers, respectively.

New NASA-funded educational initiatives make for a pipeline of products meeting the needs of today's educators in inner city schools, for NASA Explorer Schools and across the nation. Three projects include training and include: 1) WDLC [Weather Data Learning Center] , a math achievement program with data entry, inquiry-based investigations, and the application of math using weather maps and imagery for Grade 4; 2) Project 3D-VIEW, where students in Grades 5 and 6 become experts in air, life, water, land and Earth systems using 3D technologies requiring 3D glasses. A formal literacy and math piece are included, and 1200 teachers will be provided training and materials free beginning in Fall 2006, and 3) Signals of Spring, where students in Grades 7 to 8, or high school, use NASA data to explain the movement of dozens of birds, land and marine animals that are tracked by satellite. Comprehensive content in life and Earth science is taught with curricular activities, interactive mapping, image interpretation, and online journals and common misconceptions are dispelled. Scientist involvement and support for a project is essential for students who are developing process skills and performing science activities. Current research partners include Columbia University's Teachers College and Stanford University's School of Education.

The dominant framework in STEM education is the pipeline which assumes girls in general lack motivation and interest to persist in STEM fields. Recent public discourse shifts to address institutionalized discrimination and systemic barriers in STEM culture that filter out underrepresented populations. Informal education or complementary learning STEM programs offer alternative opportunities for students to explore outside of rigid school academic and social systems. Few articles look specifically at STEM complementary learning programs, and even fewer focus on the effects on girls of color. This research is a quantitative study to categorize existing mission statements and training behind organizations that provide STEM programs. The results will provide a better understanding of the relationship between practices of STEM education organizations and the programs they create. Diversity training and inclusive language in mission statements had weak correlations with increased cultural responsiveness in the program offerings. The results suggest organizations must be more intentional and explicit when implementing diversity goals.

Training Families To Learn Science Together Using Astronomical Topics

NASA Astrophysics Data System (ADS)

Noel-Storr, Jacob; Wyllie, G.; Lierheimer, D.

2012-05-01

We present a collection of messages and lessons learned from a set of Family Science programs that have been developed, implemented and/or evaluated by the RIT Insight Lab over the past 5 years. The programs are connected by their use of astronomical topics to serve as the motivator for engagement and learning. The programs all focus on the development of inquiry skills and connecting family members to each other as science learning communities, rather than focusing on the development of specific content knowledge. We show how family science programs can increase engagement in STEM for parents and their children alike, and strengthen the pipeline of the next generation of scientists and engineers.

The purpose of this paper was to describe the development and implementation of a health disparities summer internship program for minority high school students that was created to increase their knowledge of health disparities, provide hands-on training in community-engaged research, support their efforts to advocate for policy change, and further encourage youth to pursue careers in the health professions. Fifty-one high school students who were enrolled in a well-established, science-enrichment after-school program in Brooklyn, New York, participated in a 4-week summer internship program. Students conducted a literature review, focus groups/interviews, geographic mapping or survey development that focused on reducing health disparities at 1 of 15 partnering CBOs. Overall, student interns gained an increase in knowledge of racial/ethnic health disparities. There was a 36.2% increase in students expressing an interest in pursuing careers in minority health post program. The majority of the participating CBOs were able to utilize the results of the student-led research projects for their programs. In addition, research conclusions and policy recommendations based on the students' projects were given to local elected officials. As demonstrated by our program, community-academic partnerships can provide educational opportunities to strengthen the academic pipeline for students of color interested in health careers and health disparities research.

This editorial provides insights into how informatics can attract highly trained students by involving them in science, technology, engineering, and math (STEM) training at the high school level and continuing to provide mentorship and research opportunities through the formative years of their education. Our central premise is that the trajectory necessary to be expert in the emergent fields in front of them requires acceleration at an early time point. Both pathology (and biomedical) informatics are new disciplines which would benefit from involvement by students at an early stage of their education. In 2009, Michael T Lotze MD, Kirsten Livesey (then a medical student, now a medical resident at University of Pittsburgh Medical Center (UPMC)), Richard Hersheberger, PhD (Currently, Dean at Roswell Park), and Megan Seippel, MS (the administrator) launched the University of Pittsburgh Cancer Institute (UPCI) Summer Academy to bring high school students for an 8 week summer academy focused on Cancer Biology. Initially, pathology and biomedical informatics were involved only in the classroom component of the UPCI Summer Academy. In 2011, due to popular interest, an informatics track called Computer Science, Biology and Biomedical Informatics (CoSBBI) was launched. CoSBBI currently acts as a feeder program for the undergraduate degree program in bioinformatics at the University of Pittsburgh, which is a joint degree offered by the Departments of Biology and Computer Science. We believe training in bioinformatics is the best foundation for students interested in future careers in pathology informatics or biomedical informatics. We describe our approach to the recruitment, training and research mentoring of high school students to create a pipeline of exceptionally well-trained applicants for both the disciplines of pathology informatics and biomedical informatics. We emphasize here how mentoring of high school students in pathology informatics and biomedical informatics will be critical to assuring their success as leaders in the era of big data and personalized medicine.

BigDataScript: a scripting language for data pipelines.

PubMed

Cingolani, Pablo; Sladek, Rob; Blanchette, Mathieu

2015-01-01

The analysis of large biological datasets often requires complex processing pipelines that run for a long time on large computational infrastructures. We designed and implemented a simple script-like programming language with a clean and minimalist syntax to develop and manage pipeline execution and provide robustness to various types of software and hardware failures as well as portability. We introduce the BigDataScript (BDS) programming language for data processing pipelines, which improves abstraction from hardware resources and assists with robustness. Hardware abstraction allows BDS pipelines to run without modification on a wide range of computer architectures, from a small laptop to multi-core servers, server farms, clusters and clouds. BDS achieves robustness by incorporating the concepts of absolute serialization and lazy processing, thus allowing pipelines to recover from errors. By abstracting pipeline concepts at programming language level, BDS simplifies implementation, execution and management of complex bioinformatics pipelines, resulting in reduced development and debugging cycles as well as cleaner code.

A comparison of pipeline versus truck transport of bio-oil.

PubMed

Pootakham, Thanyakarn; Kumar, Amit

2010-01-01

Biomass-based energy and fuels are receiving attention because they are considered carbon neutral; i.e. the amount of CO(2) released during combustion of this biomass is nearly the same as that taken up by the plants during their growth. Bio-oil is a dark viscous liquid consisting of hydrocarbons. These are produced by fast pyrolysis of biomass. "As-is" biomass material has a low energy density (MJ m(-3)), hence, the cost of transporting this energy is high. Bio-oil has a high energy density as compared to "as-is" biomass material, consequently it helps in reducing the cost of energy transport. This study compares the life cycle assessment of transportation of bio-oil by pipeline with that by truck. The scope of the work includes the transportation of bio-oil by truck or pipeline from a centralized plant (supplied with forest biomass) to an end-user. Two cases are studied for pipeline transport of bio-oil: the first case considers a coal-based electricity supply for pumping the bio-oil through a pipeline; the second case considers an electricity supply from a renewable resource. The two cases of pipeline transport are compared to two cases of truck transport (truck trailer and super B-train truck). The life cycle greenhouse gas (GHG) emissions from the pipeline transport of bio-oil for the two cases of electricity supply are 345 and 17 g of CO(2) m(-3) km(-1), respectively. Similar values for transport by trailer (capacity - 30 m(3)) and super B-train truck (capacity - 60 m(3)) are 89 and 60 g of CO(2) m(-3) km(-1), respectively. Energy input for bio-oil transport is 3.95 MJ m(-3) km(-1) by pipeline, 2.59 MJ m(-3) km(-1) by truck and 1.66 MJ m(-3) km(-1) by super B-train truck. The results show that GHG emissions in pipeline transport are largely dependent on the source of electricity (higher for coal-based electricity). Substituting 250 m(3) day(-1) of pipeline-transported bio-oil for coal-based electricity can mitigate about 5.1 million tonnes of CO(2) per year. Overall, this study gives a comprehensive life cycle assessment of bio-oil transport comparing pipeline and truck transport.

Feeding the pipeline: academic skills training for predental students.

Markel, Geraldine; Woolfolk, Marilyn; Inglehart, Marita Rohr

2008-06-01

This article reports the outcomes of an evaluation conducted to determine if an academic skills training program for undergraduate predental students from underrepresented minority backgrounds increased the students' standardized academic skills test scores for vocabulary, reading comprehension, reading rates, spelling, and math as well as subject-specific test results in biology, chemistry, and physics. Data from standardized academic skill tests and subject-specific tests were collected at the beginning and end of the 1998 to 2006 Pipeline Programs, six-week summer enrichment programs for undergraduate predental students from disadvantaged backgrounds. In total, 179 students (75.4 percent African American, 7.3 percent Hispanic, 5.6 percent Asian American, 5 percent white) attended the programs during these nine summers. Scores on the Nelson-Denny Reading Test showed that the students improved their vocabulary scores (percentile ranks before/after: 46.80 percent/59.56 percent; p<.001), reading comprehension scores (47.21 percent/62.67 percent; p<.001), and reading rates (34.01 percent/78.31 percent; p<.001) from the beginning to the end of the summer programs. Results on the Wide Range Achievement Test III showed increases in spelling (73.58 percent/86.22 percent; p<.001) and math scores (56.98 percent/81.28 percent; p<.001). The students also improved their subject-specific scores in biology (39.07 percent/63.42 percent; p<.001), chemistry (20.54 percent/51.01 percent; p<.001), and physics (35.12 percent/61.14 percent; p<.001). To increase the number of underrepresented minority students in the dental school admissions pool, efforts are needed to prepare students from disadvantaged backgrounds for this process. These data demonstrate that a six-week enrichment program significantly improved the academic skills and basic science knowledge scores of undergraduate predental students. These improvements have the potential to enhance the performance of these students in college courses and thus increase their level of competitiveness in the dental school admissions process.

The chronic kidney disease epidemic: a challenge for nephrology training programs.

PubMed

Kohan, Donald E; Rosenberg, Mark E

2009-09-01

A major challenge facing the nephrology community in the United States is the training of adequate numbers of nephrologists to meet patient care and research needs. There is particular cause for concern because of the increasing incidence and prevalence of patients with chronic kidney disease. Data on the clinical and research nephrology workforce are incomplete or absent. However, the number of such individuals likely is inadequate to meet current and projected needs. To solve these workforce shortages, significant issues with regard to clinical and research training need to be addressed. These include funding of fellowship training, increasing the pipeline of medical students and internal medicine residents, and enhancing interest in nephrology among international and particularly US medical graduates. This review discusses these challenges facing the renal community, with emphasis on the care, prevention, and treatment of chronic kidney disease, and identifies potential pathways to developing solutions.

2015 Meeting of the National Directors of Graduate Studies in Pharmacology and Physiology

McFalls, Ashley J.; Barnett, Joey V.

2016-01-01

Researchers trained in pharmacology and physiology must possess not only a comprehensive knowledge of chemistry and the nature of compounds but also a deep understanding of physiology and predict how these compounds function in a system or organism. However, graduate programs in pharmacology and physiology have increasingly begun to focus on more reductionist approaches to basic science, neglecting training in integrative/systems physiology. In response to a decline in the competency of recent pharmacology and physiology graduates, a biennial meeting, National Directors of Graduate Studies (NDOGS) in pharmacology and physiology, was conceived to address these concerns and improve the quality of graduate education. NDOGS functions as a forum for directors of pharmacology and physiology programs to exchange ideas and tackle the challenges facing graduate education. The 2015 meeting was held on the campus of the University of Cincinnati, and each day of the meeting was allocated for discussion of a broad topic. On Friday, talks were aimed at “enhancing the professional pipeline.” On Saturday, the theme of “fitting training to emerging needs” tackled ways that universities can respond to the emerging needs of a changing society. Sunday morning updated graduate program directors about changes to National Institutes of Health T32 Training Grant applications and provided a forum for program directors to share their experiences and concerns. Throughout the meeting, presentations and discussions highlighted challenges and opportunities that apply broadly to PhD training in the biomedical sciences and revealed best practices to improve training and career preparation of PhD trainees.

Health care leadership development and training: progress and pitfalls

PubMed Central

Sonnino, Roberta E

2016-01-01

Formal training in the multifaceted components of leadership is now accepted as highly desirable for health care leaders. Despite natural leadership instincts, some core leadership competencies (“differentiating competencies”) must be formally taught or refined. Leadership development may begin at an early career stage. Despite the recognized need, the number of comprehensive leadership development opportunities is still limited. Leadership training programs in health care were started primarily as internal institutional curricula, with a limited scope, for the development of faculty or practitioners. More comprehensive national leadership programs were developed in response to the needs of specific cohorts of individuals, such as programs for women, which are designed to increase the ranks of senior women leaders in the health sciences. As some programs reach their 20th year of existence, outcomes research has shown that health care leadership training is most effective when it takes place over time, is comprehensive and interdisciplinary, and incorporates individual/institutional projects allowing participants immediate practical application of their newly acquired skills. The training should envelop all the traditional health care domains of clinical practice, education, and research, so the leader may understand all the activities taking place under his/her leadership. Early career leadership training helps to develop a pipeline of leaders for the future, setting the foundation for further development of those who may chose to pursue significant leadership opportunities later in their career. A combination of early and mid-to-late career development may represent the optimal training for effective leaders. More training programs are needed to make comprehensive leadership development widely accessible to a greater number of potential health care leaders. This paper addresses the skills that health care leaders should develop, the optimal leadership development concepts that must be acquired to succeed as a health care leader today, some resources for where such training may be obtained, and what gaps are still present in today’s system.

Sustainable and effective computing infrastructure depends critically on the skills and expertise of domain scientists and of committed and well-trained advanced computing professionals. But, in its ongoing High Performance Computing (HPC) work, Los Alamos National Laboratory noted a persistent shortage of well-prepared applicants, particularly for entry-level cluster administration, file systems administration, and high speed networking positions. Further, based upon recruiting efforts and interactions with universities graduating students in related majors of interest (e.g., computer science (CS)), there has been a long standing skillset gap, as focused training in HPC topics is typically lacking or absent in undergraduate and in evenmore » many graduate programs. Given that the effective operation and use of HPC systems requires specialized and often advanced training, that there is a recognized HPC skillset gap, and that there is intense global competition for computing and computational science talent, there is a long-standing and critical need for innovative approaches to help bridge the gap and create a well-prepared, next generation HPC workforce. Our paper places this need in the context of the HPC work and workforce requirements at Los Alamos National Laboratory (LANL) and presents one such innovative program conceived to address the need, bridge the gap, and grow an HPC workforce pipeline at LANL.

We describe an algorithm for identifying point-source transients and moving objects on reference-subtracted optical images containing artifacts of processing and instrumentation. The algorithm makes use of the supervised machine learning technique known as Random Forest. We present results from its use in the Dark Energy Survey Supernova program (DES-SN), where it was trained using a sample of 898,963 signal and background events generated by the transient detection pipeline. After reprocessing the data collected during the first DES-SN observing season (2013 September through 2014 February) using the algorithm, the number of transient candidates eligible for human scanning decreased by a factor of 13.4, while only 1.0% of the artificial Type Ia supernovae (SNe) injected into search images to monitor survey efficiency were lost, most of which were very faint events.

Objectives The purpose of this study was to identify common components of diversity pipeline programs across a national sample of nursing institutions and determine what effect these programs have on increasing underrepresented minority enrollment and graduation. Design Linked data from an electronic survey conducted November 2012 to March 2013 and American Association of Colleges of Nursing baccalaureate graduation and enrollment data (2008 and 2012). Participants Academic and administrative staff of 164 nursing schools in 26 states, including Puerto Rico in the United States. Methods Chi-square statistics were used to (1) describe organizational features of nursing diversity pipeline programs and (2) determine significant trends in underrepresented minorities’ graduation and enrollment between nursing schools with and without diversity pipeline programs Results Twenty percent (n = 33) of surveyed nursing schools reported a structured diversity pipeline program. The most frequent program measures associated with pipeline programs included mentorship, academic, and psychosocial support. Asian, Hispanic, and Native Hawaiian/Pacific Islander nursing student enrollment increased between 2008 and 2012. Hispanic/Latino graduation rates increased (7.9%–10.4%, p = .001), but they decreased among Black (6.8%–5.0%, p = .004) and Native American/Pacific Islander students (2.1 %–0.3%, p ≥ .001). Conclusions Nursing diversity pipeline programs are associated with increases in nursing school enrollment and graduation for some, although not all, minority students. Future initiatives should build on current trends while creating targeted strategies to reverse downward graduation trends among Black, Native American, and Pacific Island nursing students.

Hardware-Efficient On-line Learning through Pipelined Truncated-Error Backpropagation in Binary-State Networks

Artificial neural networks (ANNs) trained using backpropagation are powerful learning architectures that have achieved state-of-the-art performance in various benchmarks. Significant effort has been devoted to developing custom silicon devices to accelerate inference in ANNs. Accelerating the training phase, however, has attracted relatively little attention. In this paper, we describe a hardware-efficient on-line learning technique for feedforward multi-layer ANNs that is based on pipelined backpropagation. Learning is performed in parallel with inference in the forward pass, removing the need for an explicit backward pass and requiring no extra weight lookup. By using binary state variables in the feedforward network and ternary errors in truncated-error backpropagation, the need for any multiplications in the forward and backward passes is removed, and memory requirements for the pipelining are drastically reduced. Further reduction in addition operations owing to the sparsity in the forward neural and backpropagating error signal paths contributes to highly efficient hardware implementation. For proof-of-concept validation, we demonstrate on-line learning of MNIST handwritten digit classification on a Spartan 6 FPGA interfacing with an external 1Gb DDR2 DRAM, that shows small degradation in test error performance compared to an equivalently sized binary ANN trained off-line using standard back-propagation and exact errors. Our results highlight an attractive synergy between pipelined backpropagation and binary-state networks in substantially reducing computation and memory requirements, making pipelined on-line learning practical in deep networks.

2009-01-01

The pulmonary physician-scientist has a special niche to generate basic research findings and apply them to a clinical disease and perhaps impact its medical care. The availability of new high throughput-based scientific technologies in the "omics era" has made this an opportune time for physician scientists to prepare and embark on an academic career in respiratory disease research. However, maintaining an adequate flow through the research pipeline of physician-scientist investigators studying respiratory system diseases is currently a challenge. There may not be a sufficient workforce emerging to capitalize on current research opportunities. The National Heart, Lung, and Blood Institute (NHLBI) organized a workshop to assess ways to attract and properly train advanced fellows to pursue research careers in adult and pediatric lung diseases. Participants included representatives from the various pulmonary training programs, respiratory-related professional societies, and NHLBI staff. Deliberation centered on present barriers that might affect interest in pursuing research training, devising better incentives to attract more trainees, and how current research support offered by the NHLBI and the Professional Societies (in partnership with Industry and Patient Support groups) might be better coordinated and optimized to ensure a continued pipeline of pulmonary investigators. Major recommendations offered are: (1) Attract trainees to pulmonary/critical care medicine-based research careers by increasing research exposure and opportunities for high school, college, and medical students. (2) Increase awareness of the outstanding physician-scientist role models in the lung community for trainees. (3) Facilitate mechanisms by which the lung community (NHLBI, professional societies, and partners) can better support and bridge senior fellows as they transition from Institutional Training Grants (T32) to Career Series (K) awards in their early faculty career development.

Commentary: Recommendations and remaining questions for health care leadership training programs.

PubMed

Stoller, James K

2013-01-01

Effective leadership is critical for optimizing cost, access, and quality in health care. Creating a pipeline of effective health care leaders requires developing leadership competencies that differ from the usual criteria of clinical and scientific excellence by which physicians have traditionally been promoted to leadership positions. Specific competencies that differentiate effective leaders from average leaders, especially emotional intelligence and its component abilities, are essential for effective leadership.Adopting a long-standing practice from successful corporations, some health care institutions, medical societies, and business schools now offer leadership programs that address these differentiating leadership competencies. The author draws on experience with such programs through the Cleveland Clinic Academy to provide recommendations for health care leadership training and to identify unanswered questions about such programs.The author recommends that such training should be broadly available to all health care leadership communities (i.e., nurses, administrators, and physicians). A progressive curriculum, starting with foundational concepts and extending to coaching and feedback opportunities through experiential learning, recognizes the challenge of becoming an effective leader and the long time line needed to do so. Linking leadership courses to continuing medical education and to graduate credit opportunities is appealing to participants. Other recommendations focus on the importance of current leaders' involvement in nominating emerging leaders for participation, embedding leadership development discussions in faculty's professional reviews, and blending discussion of frameworks and theory with practical, experiential lessons. The author identifies questions about the benefits of formal health care leadership training that remain to be answered.

Optimal Energy Consumption Analysis of Natural Gas Pipeline

PubMed Central

Liu, Enbin; Li, Changjun; Yang, Yi

2014-01-01

There are many compressor stations along long-distance natural gas pipelines. Natural gas can be transported using different boot programs and import pressures, combined with temperature control parameters. Moreover, different transport methods have correspondingly different energy consumptions. At present, the operating parameters of many pipelines are determined empirically by dispatchers, resulting in high energy consumption. This practice does not abide by energy reduction policies. Therefore, based on a full understanding of the actual needs of pipeline companies, we introduce production unit consumption indicators to establish an objective function for achieving the goal of lowering energy consumption. By using a dynamic programming method for solving the model and preparing calculation software, we can ensure that the solution process is quick and efficient. Using established optimization methods, we analyzed the energy savings for the XQ gas pipeline. By optimizing the boot program, the import station pressure, and the temperature parameters, we achieved the optimal energy consumption. By comparison with the measured energy consumption, the pipeline now has the potential to reduce energy consumption by 11 to 16 percent. PMID:24955410

Efficient k-Winner-Take-All Competitive Learning Hardware Architecture for On-Chip Learning

PubMed Central

Ou, Chien-Min; Li, Hui-Ya; Hwang, Wen-Jyi

2012-01-01

A novel k-winners-take-all (k-WTA) competitive learning (CL) hardware architecture is presented for on-chip learning in this paper. The architecture is based on an efficient pipeline allowing k-WTA competition processes associated with different training vectors to be performed concurrently. The pipeline architecture employs a novel codeword swapping scheme so that neurons failing the competition for a training vector are immediately available for the competitions for the subsequent training vectors. The architecture is implemented by the field programmable gate array (FPGA). It is used as a hardware accelerator in a system on programmable chip (SOPC) for realtime on-chip learning. Experimental results show that the SOPC has significantly lower training time than that of other k-WTA CL counterparts operating with or without hardware support.

Teaching About the Brain and Reaching the Community: Undergraduates in the Pipeline Neuroscience Program at the University of Pennsylvania

PubMed Central

Edlow, Brian L.; Hamilton, Karen; Hamilton, Roy H.

2007-01-01

This article provides an overview of the University of Pennsylvania School of Medicine’s Pipeline Neuroscience Program, a multi-tiered mentorship and education program for Philadelphia high school students in which University of Pennsylvania undergraduates are integrally involved. The Pipeline Neuroscience Program provides mentorship and education for students at all levels. High school students are taught by undergraduates, who learn from medical students who, in turn, are guided by neurology residents and fellows. Throughout a semester-long course, undergraduates receive instruction in neuroanatomy, neuroscience, and clinical neurology as part of the Pipeline’s case-based curriculum. During weekly classes, undergraduates make the transition from students to community educators by integrating their new knowledge into lesson plans that they teach to small groups of medically and academically underrepresented Philadelphia high school students. The Pipeline program thus achieves the dual goals of educating undergraduates about neuroscience and providing them with an opportunity to perform community service. PMID:23493190

DIVERSITY IN THE BIOMEDICAL RESEARCH WORKFORCE: DEVELOPING TALENT

PubMed Central

McGee, Richard; Saran, Suman; Krulwich, Terry A.

2012-01-01

Much has been written about the need for and barriers to achievement of greater diversity in the biomedical workforce from the perspectives of gender, race and ethnicity; this is not a new topic. These discussions often center around a ‘pipeline metaphor’ which imagines students flowing through a series of experiences to eventually arrive at a science career. Here we argue that diversity will only be achieved if the primary focus is on: what is happening within the pipeline, not just counting individuals entering and leaving it; de-emphasizing achieving academic milestones by ‘typical’ ages; and adopting approaches that most effectively develop talent. Students may develop skills at different rates based on factors such as earlier access to educational resources, exposure to science (especially research experiences), and competing demands for time and attention during high school and college. Therefore, there is wide variety among students at any point along the pipeline. Taking this view requires letting go of imagining the pipeline as a sequence of age-dependent steps in favor of milestones of skill and talent development decoupled from age or educational stage. Emphasizing talent development opens up many new approaches for science training outside of traditional degree programs. This article provides examples of such approaches, including interventions at the post-baccalaureate and PhD levels, as well as a novel coaching model that incorporates well-established social science theories and complements traditional mentoring. These approaches could significantly impact diversity by developing scientific talent, especially among currently underrepresented minorities. PMID:22678863

Here, we describe an algorithm for identifying point-source transients and moving objects on reference-subtracted optical images containing artifacts of processing and instrumentation. The algorithm makes use of the supervised machine learning technique known as Random Forest. We present results from its use in the Dark Energy Survey Supernova program (DES-SN), where it was trained using a sample of 898,963 signal and background events generated by the transient detection pipeline. After reprocessing the data collected during the first DES-SN observing season (2013 September through 2014 February) using the algorithm, the number of transient candidates eligible for human scanning decreased by amore » factor of 13.4, while only 1.0% of the artificial Type Ia supernovae (SNe) injected into search images to monitor survey efficiency were lost, most of which were very faint events. Here we characterize the algorithm's performance in detail, and we discuss how it can inform pipeline design decisions for future time-domain imaging surveys, such as the Large Synoptic Survey Telescope and the Zwicky Transient Facility. An implementation of the algorithm and the training data used in this paper are available at at http://portal.nersc.gov/project/dessn/autoscan.« less

The Implementation of an Innovative High School Mentoring Program Designed to Enhance Diversity and Provide a Pathway for Future Careers in Healthcare Related Fields.

PubMed

Patel, Salma I; Rodríguez, Patricia; Gonzales, Rayna J

2015-09-01

Although the population of diverse applicants applying to medical school has increased over recent years (AAMC Diversity in Medical Education: Facts and Figures 2012); efforts persist to ensure the continuance of this increasing trend. Mentoring students at an early age may be an effective method by which to accomplish diversity within the applicant pool. Having a diverse physician population is more likely able to adequately address the healthcare needs of our diverse population. The purpose of this study is to initiate a pipeline program, called the Medical Student Mentorship Program (MSMP), designed to specifically target high school students from lower economic status, ethnic, or racial underrepresented populations. High school students were paired with medical students, who served as primary mentors to facilitate exposure to processes involved in preparing and training for careers in medicine and other healthcare-related fields as well as research. Mentors were solicited from first and second year medical students at the University of Arizona College of Medicine-Phoenix (UACOM-P). Two separate cohorts of mentees were selected based on an application process from a local high school for the school years 2010-2011 and 2011-2012. Anonymous mentee and mentor surveys were used to evaluate the success of the MSMP. A total of 16 pairs of mentees and mentors in the 2010-2011 (Group 1) and 2011-2012 (Group 2) studies participated in MSMP. High school students reported that they were more likely to apply to medical school after participating in the program. Mentees also reported that they received a significant amount of support, helpful information, and guidance from their medical student mentors. Overall, feedback from mentees and mentors was positive and they reported that their participation was rewarding. Mentees were contacted 2 to 3 years post MSMP participation as sophomores or juniors in college, and all reported that they were on a pre-healthcare career track. The MSMP may serve as an effective pipeline program to promote future diversity in college and graduate training programs for future careers in science and medicine.

Are Time-Limited Grants Likely to Stimulate Sustained Growth in Primary Care Residency Training? A Study of the Primary Care Residency Expansion Program.

PubMed

Chen, Rossan Melissa; Petterson, Stephen; Bazemore, Andrew; Grumbach, Kevin

2015-09-01

To examine the perceived likelihood of sustaining new residency positions funded by five-year (2010-2015) Primary Care Residency Expansion (PCRE) grants from the Health Resources and Services Administration, which aimed to increase training output to address primary care workforce issues. During September-December 2013, the authors administered an online or telephone survey to program directors whose residency programs received PCRE grants. The main outcome measure was perceived likelihood of sustaining the expanded residency positions beyond the expiration of the grant, in the outlying years of 2016 and 2017 (when the positions will be partially supported) and after 2017 (when the positions will be unsupported). Of 78 eligible program directors, 62 responded (response rate = 79.5%). Twenty-eight (45.1%; 95% CI 32.9%-57.9%) reported that their programs were unlikely to, very unlikely to, or not planning to continue the expanded positions after the PCRE grant expires. Overall, 14 (22.5%) reported having secured full funding to support the expanded positions beyond 2017. Family medicine and pediatrics program directors were significantly less likely than internal medicine program directors to report having secured funding for the outlying years (P = .02). This study suggests that an approach to primary care residency training expansion that relies on time-limited grants is unlikely to produce sustainable growth of the primary care pipeline. Policy makers should instead implement systemic reform of graduate medical education (GME) financing and designate reliable sources of funding, such as Medicare and Medicaid GME funds, for new primary care residency positions.

The Cleveland State University Minority Engineering Program Pipeline consist of programs which foster engineering career awareness, academic enrichment, and professional development for historically underrepresented minority studies. The programs involved are the Access to Careers in Engineering (ACE) Program for high school pre-engineering students: the LINK Program for undergraduate students pursuing degree which include engineering; and the PEP (Pre-calculus Enrichment Program) and EPIC (Enrichment Program in Calculus) mathematics programs for undergraduate academic enrichment. The pipeline is such that high school graduates from the ACE Program who enroll at Cleveland State University in pursuit of engineering degrees are admitted to the LINK Program for undergraduate level support. LINK Program students are among the minority participants who receive mathematics enrichment through the PEP and EPIC Programs for successful completion of their engineering required math courses. THese programs are interdependent and share the goal of preparing minority students for engineering careers by enabling them to achieve academically and obtain college degree and career related experience.

Augmented reality (AR), mixed reality (MR), and virtual reality devices are enabling technologies that may facilitate effective communication in healthcare between those with information and knowledge (clinician/specialist; expert; educator) and those seeking understanding and insight (patient/family; non-expert; learner). Investigators initiated an exploratory program to enable the study of AR/MR use-cases in acute care clinical and instructional settings. Academic clinician educators, computer scientists, and diagnostic imaging specialists conducted a proof-of-concept project to 1) implement a core holoimaging pipeline infrastructure and open-access repository at the study institution, and 2) use novel AR/MR techniques on off-the-shelf devices with holoimages generated by the infrastructure to demonstrate their potential role in the instructive communication of complex medical information. The study team successfully developed a medical holoimaging infrastructure methodology to identify, retrieve, and manipulate real patients' de-identified computed tomography and magnetic resonance imagesets for rendering, packaging, transfer, and display of modular holoimages onto AR/MR headset devices and connected displays. Holoimages containing key segmentations of cervical and thoracic anatomic structures and pathology were overlaid and registered onto physical task trainers for simulation-based "blind insertion" invasive procedural training. During the session, learners experienced and used task-relevant anatomic holoimages for central venous catheter and tube thoracostomy insertion training with enhanced visual cues and haptic feedback. Direct instructor access into the learner's AR/MR headset view of the task trainer was achieved for visual-axis interactive instructional guidance. Investigators implemented a core holoimaging pipeline infrastructure and modular open-access repository to generate and enable access to modular holoimages during exploratory pilot stage applications for invasive procedure training that featured innovative AR/MR techniques on off-the-shelf headset devices.

The Consortium for Advancing Renewable Energy (CARET) is a research and education program which uses the theme of renewable energy to build a minority scientist pipeline. CARET is also a consortium of four universities and NASA Lewis Research Center working together to promote science education and research to minority students using the theme of renewable energy. The consortium membership includes the HBCUs (Historically Black Colleges and Universities), Fisk, Wilberforce and Central State Universities as well as Kent State University and NASA Lewis Research Center. The various stages of this pipeline provide participating students experiences with a different emphasis. Some emphasize building enthusiasm for the classroom study of science and technology while others emphasize the nature of research in these disciplines. Still others focus on relating a practical application to science and technology. And, of great importance to the success of the program are the interfaces between the various stages. Successfully managing these transitions is a requirement for producing trained scientists, engineers and technologists. Presentations describing the CARET program have been given at this year's HBCU Research Conference at the Ohio Aerospace Institute and as a seminar in the Solar Circle Seminar series of the Photovoltaic and Space Environments Branch at NASA Lewis Research Center. In this report, we will describe the many positive achievements toward the fulfillment of the goals and outcomes of our program. We will begin with a description of the interactions among the consortium members and end with a description of the activities of each of the member institutions .

Natural Gas Pipeline Replacement Programs Reduce Methane Leaks and Improve Consumer Safety

NASA Astrophysics Data System (ADS)

Jackson, R. B.

2015-12-01

From production through distribution, oil and natural gas infrastructure provide the largest source of anthropogenic methane in the U.S. and the second largest globally. To examine the prevalence of natural gas leaks downstream in distribution systems, we mapped methane leaks across 595, 750, and 247 road miles of three U.S. cities—Durham, NC, Cincinnati, OH, and Manhattan, NY, respectively—at different stages of pipeline replacement of cast iron and other older materials. We compare results with those for two cities we mapped previously, Boston and Washington, D.C. Overall, cities with pipeline replacement programs have considerably fewer leaks per mile than cities without such programs. Similar programs around the world should provide additional environmental, economic, and consumer safety benefits.

Understanding the Leaky Pipeline: Perceived Barriers to Pursuing a Career in Medicine or Dentistry Among Underrepresented-in-Medicine Undergraduate Students.

PubMed

Freeman, Brandi Kaye; Landry, Alden; Trevino, Robert; Grande, David; Shea, Judy A

2016-07-01

Representation of persons from diverse backgrounds remains a persistent challenge for medicine and dentistry workforces. Past research has focused on quantifying factors such as markers of educational achievement to explain the difficulty of increasing diversity within the professions. There has been less effort toward understanding the perspectives of undergraduate students on the threshold of applying to medical/dental school about distinct barriers to pursuing a medical or dental career and continuing through the training pipeline. In 2012 and 2013, the authors conducted a qualitative study of undergraduate students participating in the Tour for Diversity in Medicine, a program where minority physicians and dentists visit colleges with large fractions of minority students to encourage careers in the health professions. Focus groups were convened during the visits to examine perceived barriers to pursuing careers in medicine and dentistry and challenges identified through thematic content analysis. Eighty-two students participated in discussions at 11 colleges visited between September 2012 and February 2013. Students described challenges including inadequate institutional resources (e.g., sparse clinical opportunities), strained personal resources (e.g., conflict arising from familial pressure), inadequate guidance and mentoring to assist with key career decisions, and societal barriers. For participants, these challenges caused them to question the viability of persisting in the pipeline to a medical or dental career. Solving the issue of diversity in medicine and dentistry is multifaceted, but elucidated challenges from the undergraduate student perspective offer targeted areas where intervention may help remedy barriers and decrease pipeline leakiness.

Diversity in the biomedical research workforce: developing talent.

PubMed

McGee, Richard; Saran, Suman; Krulwich, Terry A

2012-01-01

Much has been written about the need for and barriers to achievement of greater diversity in the biomedical workforce from the perspectives of gender, race, and ethnicity; this is not a new topic. These discussions often center around a "pipeline" metaphor that imagines students flowing through a series of experiences to eventually arrive at a science career. Here we argue that diversity will only be achieved if the primary focus is on (1) what is happening within the pipeline, not just counting individuals entering and leaving it; (2) de-emphasizing the achievement of academic milestones by typical ages; and (3) adopting approaches that most effectively develop talent. Students may develop skills at different rates based on factors such as earlier access to educational resources, exposure to science (especially research experiences), and competing demands for time and attention during high school and college. Therefore, there is wide variety among students at any point along the pipeline. Taking this view requires letting go of imagining the pipeline as a sequence of age-dependent steps in favor of milestones of skill and talent development decoupled from age or educational stage. Emphasizing talent development opens up many new approaches for science training outside of traditional degree programs. This article provides examples of such approaches, including interventions at the postbaccalaureate and PhD levels, as well as a novel coaching model that incorporates well-established social science theories and complements traditional mentoring. These approaches could significantly impact diversity by developing scientific talent, especially among currently underrepresented minorities. © 2012 Mount Sinai School of Medicine.

Adaptive thinking & leadership simulation game training for special forces officers.

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

Raybourn, Elaine Marie; Mendini, Kip; Heneghan, Jerry

Complex problem solving approaches and novel strategies employed by the military at the squad, team, and commander level are often best learned experimentally. Since live action exercises can be costly, advances in simulation game training technology offer exciting ways to enhance current training. Computer games provide an environment for active, critical learning. Games open up possibilities for simultaneous learning on multiple levels; players may learn from contextual information embedded in the dynamics of the game, the organic process generated by the game, and through the risks, benefits, costs, outcomes, and rewards of alternative strategies that result from decision making. Inmore » the present paper we discuss a multiplayer computer game simulation created for the Adaptive Thinking & Leadership (ATL) Program to train Special Forces Team Leaders. The ATL training simulation consists of a scripted single-player and an immersive multiplayer environment for classroom use which leverages immersive computer game technology. We define adaptive thinking as consisting of competencies such as negotiation and consensus building skills, the ability to communicate effectively, analyze ambiguous situations, be self-aware, think innovatively, and critically use effective problem solving skills. Each of these competencies is an essential element of leader development training for the U.S. Army Special Forces. The ATL simulation is used to augment experiential learning in the curriculum for the U.S. Army JFK Special Warfare Center & School (SWCS) course in Adaptive Thinking & Leadership. The school is incorporating the ATL simulation game into two additional training pipelines (PSYOPS and Civil Affairs Qualification Courses) that are also concerned with developing cultural awareness, interpersonal communication adaptability, and rapport-building skills. In the present paper, we discuss the design, development, and deployment of the training simulation, and emphasize how the multiplayer simulation game is successfully used in the Special Forces Officer training program.« less

Developing physician-leaders: key competencies and available programs.

PubMed

Stoller, James K

2008-01-01

Because effective leadership is critical to organizational success, frontrunner organizations cultivate leaders for bench depth and pipeline development. The many challenges in healthcare today create a special need for great leadership. This paper reviews the leadership competencies needed by physician-leaders and current experience with developing physician-leaders in healthcare institution-sponsored programs. On the basis of this review, six key leadership competency domains are proposed: 1. technical skills and knowledge (regarding operational, financial, and information systems, human resources, and strategic planning), 2. industry knowledge (e.g., regarding clinical processes, regulation, and healthcare trends), 3. problem-solving skills, 4. emotional intelligence, 5. communication, and 6. a commitment to lifelong learning. Review of current experience indicates that, in addition to leadership training through degree and certificate-granting programs (e.g., by universities and/or official medical societies), healthcare institutions themselves are developing intramural programs to cultivate physician-leaders. Greater attention is needed to assessing the impact and effectiveness of such programs in developing leaders and benefiting organizational outcomes.

In this paper, we describe the optical imaging data processing pipeline developed for the Subaru Telescope's Hyper Suprime-Cam (HSC) instrument. The HSC Pipeline builds on the prototype pipeline being developed by the Large Synoptic Survey Telescope's Data Management system, adding customizations for HSC, large-scale processing capabilities, and novel algorithms that have since been reincorporated into the LSST codebase. While designed primarily to reduce HSC Subaru Strategic Program (SSP) data, it is also the recommended pipeline for reducing general-observer HSC data. The HSC pipeline includes high-level processing steps that generate coadded images and science-ready catalogs as well as low-level detrending and image characterizations.

Since 2005, the NOAA Ernest F. Hollings Undergraduate Scholarship Program has provided tuition support and paid summer internship opportunities at NOAA to exceptional students majoring in the geosciences. The purpose of the scholarship program is to train students in NOAA mission fields. Multiple methods were used to track the career trajectories of Hollings alumni, including mining LinkedIn data, conducting an impact analysis based on a professionally developed web-based evaluation survey, and a web-based alumni update system. At least one postgraduate record was recorded for 80% of Hollings Scholarship alumni. Of the alumni reached, more than 75% continued on to graduate school in a NOAA mission field, and 86% of those graduate degrees were in a NOAA mission field or other STEM field. More than 60% of alumni had at least one professional record, with the most alumni working in private industry, followed by nongovernmental organizations and federal, state and local government.

Feature extraction from imagery is an important and long-standing problem in remote sensing. In this paper, we report on work using genetic programming to perform feature extraction simultaneously from multispectral and digital elevation model (DEM) data. We use the GENetic Imagery Exploitation (GENIE) software for this purpose, which produces image-processing software that inherently combines spatial and spectral processing. GENIE is particularly useful in exploratory studies of imagery, such as one often does in combining data from multiple sources. The user trains the software by painting the feature of interest with a simple graphical user interface. GENIE then uses genetic programming techniques to produce an image-processing pipeline. Here, we demonstrate evolution of image processing algorithms that extract a range of land cover features including towns, wildfire burnscars, and forest. We use imagery from the DOE/NNSA Multispectral Thermal Imager (MTI) spacecraft, fused with USGS 1:24000 scale DEM data.

Building Effective Pipelines to Increase Diversity in the Geosciences

NASA Astrophysics Data System (ADS)

Snow, E.; Robinson, C. R.; Neal-Mujahid, R.

2017-12-01

The U.S. Geological Survey (USGS) recognizes and understands the importance of a diverse workforce in advancing our science. Valuing Differences is one of the guiding principles of the USGS, and is the critical basis of the collaboration among the Youth and Education in Science (YES) program in the USGS Office of Science, Quality, and Integrity (OSQI), the Office of Diversity and Equal Opportunity (ODEO), and USGS science centers to build pipeline programs targeting diverse young scientists. Pipeline programs are robust, sustained relationships between two entities that provide a pathway from one to the other, in this case, from minority serving institutions to the USGS. The USGS has benefited from pipeline programs for many years. Our longest running program, with University of Puerto Rico Mayaguez (UPR), is a targeted outreach and internship program that has been managed by USGS scientists in Florida since the mid-1980's Originally begun as the Minority Participation in the Earth Sciences (MPES ) Program, it has evolved over the years, and in its several forms has brought dozens of interns to the USGS. Based in part on that success, in 2006 USGS scientists in Woods Hole MA worked with their Florida counterparts to build a pipeline program with City College of New York (CCNY). In this program, USGS scientists visit CCNY monthly, giving a symposium and meeting with students and faculty. The talks are so successful that the college created a course around them. In 2017, the CCNY and UPR programs brought 12 students to the USGS for summer internships. The CCNY model has been so successful that USGS is exploring creating similar pipeline programs. The YES office is coordinating with ODEO and USGS science centers to identify partner universities and build relationships that will lead to robust partnership where USGS scientists will visit regularly to engage with faculty and students and recruit students for USGS internships. The ideal partner universities will have a high population of underserved students, strong support for minority and first-generation students, proximity to a USGS office, and faculty and/or majors in several of the fields most important to USGS science: geology, geochemistry, energy, biology, ecology, environmental health, hydrology, climate science, GIS, high-capacity computing, and remote sensing.

SUNY Oneonta Earth Sciences Outreach Program (ESOP) - Generating New Drilling Prospects for Geoscience Programs

NASA Astrophysics Data System (ADS)

Ellis, T. D.; Ebert, J. R.

2010-12-01

The SUNY Oneonta ESOP is a National Science Foundation-funded program that, since 2005, has striven to address the dearth of students graduating with baccalaureate degrees in geoscience disciplines. In large part, its goal has been to provide talented STEM-oriented students with dual-enrollment college-level geoscience programs run by their local teachers for college credit. These high-school upperclassman experiences have been shown to be effective in recruiting talented students to geoscience fields, and we believe that this program is a model by which more baccalaureate programs can locate "new drilling prospects" to keep the pipeline of talented and trained geoscientists flowing into the workforce. In this presentation, we will highlight the current efforts to expand ESOP to other high schools around the country and in recruiting other colleges and universities to create their own dual-enrollment programs. We will also highlight how a senior-level geoscience course is ideal for providing students with meaningful geoscience inquiry experiences, and how we plan to support such efforts through the online teaching and learning cohorts designed to foster collaborative inquiry activities.

NASA Sounding Rocket Program Educational Outreach

Rosanova, G.

2013-01-01

Educational and public outreach is a major focus area for the National Aeronautics and Space Administration (NASA). The NASA Sounding Rocket Program (NSRP) shares in the belief that NASA plays a unique and vital role in inspiring future generations to pursue careers in science, mathematics, and technology. To fulfill this vision, the NSRP engages in a variety of educator training workshops and student flight projects that provide unique and exciting hands-on rocketry and space flight experiences. Specifically, the Wallops Rocket Academy for Teachers and Students (WRATS) is a one-week tutorial laboratory experience for high school teachers to learn the basics of rocketry, as well as build an instrumented model rocket for launch and data processing. The teachers are thus armed with the knowledge and experience to subsequently inspire the students at their home institution. Additionally, the NSRP has partnered with the Colorado Space Grant Consortium (COSGC) to provide a "pipeline" of space flight opportunities to university students and professors. Participants begin by enrolling in the RockOn! Workshop, which guides fledgling rocketeers through the construction and functional testing of an instrumentation kit. This is then integrated into a sealed canister and flown on a sounding rocket payload, which is recovered for the students to retrieve and process their data post flight. The next step in the "pipeline" involves unique, user-defined RockSat-C experiments in a sealed canister that allow participants more independence in developing, constructing, and testing spaceflight hardware. These experiments are flown and recovered on the same payload as the RockOn! Workshop kits. Ultimately, the "pipeline" culminates in the development of an advanced, user-defined RockSat-X experiment that is flown on a payload which provides full exposure to the space environment (not in a sealed canister), and includes telemetry and attitude control capability. The RockOn! and RockSat-C elements of the "pipeline" have been successfully demonstrated by five annual flights thus far from Wallops Flight Facility. RockSat-X has successfully flown twice, also from Wallops. The NSRP utilizes launch vehicles comprised of military surplus rocket motors (Terrier-Improved Orion and Terrier-Improved Malemute) to execute these missions. The NASA Sounding Rocket Program is proud of its role in inspiring the "next generation of explorers" and is working to expand its reach to all regions of the United States and the international community as well.

The increasing world demand and record-high costs for energy and mineral resources, along with the attendant environmental and climate concerns, have escalated the need for trained geophysicists to unprecedented levels. This is not only a national need; it's a critical global need. As Earth scientists and educators we must seriously ask if our geophysics pipeline can adequately address this crisis. One program that has helped to answer this question in the affirmative for 25 years is SAGE (Summer of Applied Geophysical Experience). SAGE continues to develop with new faculty, new collaborations, and additional ways to support student participation during and after SAGE. ?? 2008 Society of Exploration Geophysicists.

GSFC Technical Outreach: The Capitol College Model

NASA Technical Reports Server (NTRS)

Marius, Julio L.; Wagner, David

2008-01-01

In February 2005, as part of the National Aeronautic and Space Administration (NASA) Technical Outreach Program, Goddard Space Flight Center (GSFC) awarded Capitol College of Laurel, Maryland an Educational Grant to establish a Space Operation academic curriculum to meet the future needs of mission operations engineers. This was in part due to the aerospace industry and GSFC concerns that a large number of professional engineers are projected to retire in the near term with evidence showing that current enrollment in engineering schools will not produce sufficient number of space operation trained engineers that will meet industry and government demands. Capitol College, under the agreement of the Educational Grant, established the Space Operations Institute (SOI) with a new curriculum in Space Operations that was approved and certified by the State of Maryland. The SO1 programs focuses on attracting, recruiting, and training a pipeline of highly qualified engineers with experience in mission operations, system engineering and development. The selected students are integrated as members of the engineering support team in any of the missions supported by the institute. The students are mentored by professional engineers from several aerospace companies that support GSFC. Initially, the institute was involved in providing console engineers and mission planning trainees for the Upper Atmosphere Research Satellite (UARS), the Earth Radiation Budget Satellite (ERBS) and the Total Ozone Mapping Spectrometer mission (TOMS). Subsequently, the students were also involved in the technology refresh of the TOMS ground system and other mission operations development. Further mission assignment by GSFC management included participation in the Tropical Rainfall Measuring Mission (TRMM) mission operations and ground system technology refresh. The SOI program has been very successful. Since October 2005, sixty-four students have been enrolled in the SOI program and twenty-five have already graduated from the program, nineteen of whom are employed by company's supporting GSFC. Due to the success of the program, the initial grant period was extended for another period of two years. This paper presents the process that established the SOI as a viable pipeline of mission operations engineers, the lessons learned in the process of dealing with grants, and experience gained in mentoring engineering students that are responsible for particular areas of expertise and functionality. This paper can also be considered a case study and model for integrating a student team with government and industry professionals in the real world of mission operations.

We describe an algorithm for identifying point-source transients and moving objects on reference-subtracted optical images containing artifacts of processing and instrumentation. The algorithm makes use of the supervised machine learning technique known as Random Forest. We present results from its use in the Dark Energy Survey Supernova program (DES-SN), where it was trained using a sample of 898,963 signal and background events generated by the transient detection pipeline. After reprocessing the data collected during the first DES-SN observing season (2013 September through 2014 February) using the algorithm, the number of transient candidates eligible for human scanning decreased by a factormore » of 13.4, while only 1.0 percent of the artificial Type Ia supernovae (SNe) injected into search images to monitor survey efficiency were lost, most of which were very faint events. Here we characterize the algorithm's performance in detail, and we discuss how it can inform pipeline design decisions for future time-domain imaging surveys, such as the Large Synoptic Survey Telescope and the Zwicky Transient Facility.« less

There is a shortage of physicians to care for underserved populations. Medical educators at The Warren Alpert Medical School of Brown University have used five years of Health Resources and Services Administration funding to train medical students to provide outstanding primary care for underserved populations. The grant has two major goals: 1) to increase the number of graduating medical students who practice primary care in underserved communities ("Professional Development"); and 2) to prepare all medical school graduates to care for underserved patients, regardless of specialty choice ("Curriculum Development"). Professional Development, including a new scholarly concentration and an eight-year primary care pipeline, has been achieved in partnership with the Program in Liberal Medical Education, the medical school's Admissions Committee, and an Area Health Education Center. Curriculum Development has involved systematic recruitment of clinical training sites and disease-specific curricula including tools for providing care to vulnerable populations. A comprehensive, longitudinal evaluation is ongoing.

Unresolved Galaxy Classifier for ESA/Gaia mission: Support Vector Machines approach

NASA Astrophysics Data System (ADS)

Bellas-Velidis, Ioannis; Kontizas, Mary; Dapergolas, Anastasios; Livanou, Evdokia; Kontizas, Evangelos; Karampelas, Antonios

A software package Unresolved Galaxy Classifier (UGC) is being developed for the ground-based pipeline of ESA's Gaia mission. It aims to provide an automated taxonomic classification and specific parameters estimation analyzing Gaia BP/RP instrument low-dispersion spectra of unresolved galaxies. The UGC algorithm is based on a supervised learning technique, the Support Vector Machines (SVM). The software is implemented in Java as two separate modules. An offline learning module provides functions for SVM-models training. Once trained, the set of models can be repeatedly applied to unknown galaxy spectra by the pipeline's application module. A library of galaxy models synthetic spectra, simulated for the BP/RP instrument, is used to train and test the modules. Science tests show a very good classification performance of UGC and relatively good regression performance, except for some of the parameters. Possible approaches to improve the performance are discussed.

A De-Novo Genome Analysis Pipeline (DeNoGAP) for large-scale comparative prokaryotic genomics studies.

PubMed

Thakur, Shalabh; Guttman, David S

2016-06-30

Comparative analysis of whole genome sequence data from closely related prokaryotic species or strains is becoming an increasingly important and accessible approach for addressing both fundamental and applied biological questions. While there are number of excellent tools developed for performing this task, most scale poorly when faced with hundreds of genome sequences, and many require extensive manual curation. We have developed a de-novo genome analysis pipeline (DeNoGAP) for the automated, iterative and high-throughput analysis of data from comparative genomics projects involving hundreds of whole genome sequences. The pipeline is designed to perform reference-assisted and de novo gene prediction, homolog protein family assignment, ortholog prediction, functional annotation, and pan-genome analysis using a range of proven tools and databases. While most existing methods scale quadratically with the number of genomes since they rely on pairwise comparisons among predicted protein sequences, DeNoGAP scales linearly since the homology assignment is based on iteratively refined hidden Markov models. This iterative clustering strategy enables DeNoGAP to handle a very large number of genomes using minimal computational resources. Moreover, the modular structure of the pipeline permits easy updates as new analysis programs become available. DeNoGAP integrates bioinformatics tools and databases for comparative analysis of a large number of genomes. The pipeline offers tools and algorithms for annotation and analysis of completed and draft genome sequences. The pipeline is developed using Perl, BioPerl and SQLite on Ubuntu Linux version 12.04 LTS. Currently, the software package accompanies script for automated installation of necessary external programs on Ubuntu Linux; however, the pipeline should be also compatible with other Linux and Unix systems after necessary external programs are installed. DeNoGAP is freely available at https://sourceforge.net/projects/denogap/ .

A visual programming environment for the Navier-Stokes computer

1988-01-01

The Navier-Stokes computer is a high-performance, reconfigurable, pipelined machine designed to solve large computational fluid dynamics problems. Due to the complexity of the architecture, development of effective, high-level language compilers for the system appears to be a very difficult task. Consequently, a visual programming methodology has been developed which allows users to program the system at an architectural level by constructing diagrams of the pipeline configuration. These schematic program representations can then be checked for validity and automatically translated into machine code. The visual environment is illustrated by using a prototype graphical editor to program an example problem.

2011-02-07

The rapid increase in genomic and genome-scale data is resulting in unprecedented levels of discrete sequence data available for phylogenetic analyses. Major analytical impasses exist, however, prior to analyzing these data with existing phylogenetic software. Obstacles include the management of large data sets without standardized naming conventions, identification and filtering of orthologous clusters of proteins or genes, and the assembly of alignments of orthologous sequence data into individual and concatenated super alignments. Here we report the production of an automated pipeline, Hal that produces multiple alignments and trees from genomic data. These alignments can be produced by a choice of four alignment programs and analyzed by a variety of phylogenetic programs. In short, the Hal pipeline connects the programs BLASTP, MCL, user specified alignment programs, GBlocks, ProtTest and user specified phylogenetic programs to produce species trees. The script is available at sourceforge (http://sourceforge.net/projects/bio-hal/). The results from an example analysis of Kingdom Fungi are briefly discussed.

2014-01-01

MOSAIK is a stable, sensitive and open-source program for mapping second and third-generation sequencing reads to a reference genome. Uniquely among current mapping tools, MOSAIK can align reads generated by all the major sequencing technologies, including Illumina, Applied Biosystems SOLiD, Roche 454, Ion Torrent and Pacific BioSciences SMRT. Indeed, MOSAIK was the only aligner to provide consistent mappings for all the generated data (sequencing technologies, low-coverage and exome) in the 1000 Genomes Project. To provide highly accurate alignments, MOSAIK employs a hash clustering strategy coupled with the Smith-Waterman algorithm. This method is well-suited to capture mismatches as well as short insertions and deletions. To support the growing interest in larger structural variant (SV) discovery, MOSAIK provides explicit support for handling known-sequence SVs, e.g. mobile element insertions (MEIs) as well as generating outputs tailored to aid in SV discovery. All variant discovery benefits from an accurate description of the read placement confidence. To this end, MOSAIK uses a neural-network based training scheme to provide well-calibrated mapping quality scores, demonstrated by a correlation coefficient between MOSAIK assigned and actual mapping qualities greater than 0.98. In order to ensure that studies of any genome are supported, a training pipeline is provided to ensure optimal mapping quality scores for the genome under investigation. MOSAIK is multi-threaded, open source, and incorporated into our command and pipeline launcher system GKNO (http://gkno.me).

2017-12-01

An innovative certificate program aimed at expanding the rural pharmacy workforce, increasing the number of pharmacists with expertise in rural practice, and improving healthcare outcomes in rural North Carolina is described. Predicted shortages of primary care physicians and closures of critical access hospitals are expected to worsen existing health disparities. Experiential education in schools and colleges of pharmacy primarily takes place in academic medical centers and, unlike experiential education in medical schools, rarely emphasizes the provision of patient care in rural U.S. communities, where chronic diseases are prevalent and many residents struggle with poverty and poor access to healthcare. To help address these issues, UNC Eshelman School of Pharmacy developed the 3-year Rural Pharmacy Health Certificate program. The program curriculum includes 4 seminar courses, interprofessional education and interaction with medical students, embedding of each pharmacy student into a specific rural community for the duration of training, longitudinal ambulatory care practice experiences, community engagement initiatives, leadership training, development and implementation of a population health project, and 5 pharmacy practice experiences in rural settings. The Rural Pharmacy Health Certificate program at UNC Eshelman School of Pharmacy seeks to transform rural pharmacy practice by creating a pipeline of rural pharmacy leaders and teaching a unique skillset that will be beneficial to healthcare systems, communities, and patients.

Mathematical simulation for compensation capacities area of pipeline routes in ship systems

NASA Astrophysics Data System (ADS)

Ngo, G. V.; Sakhno, K. N.

2018-05-01

In this paper, the authors considered the problem of manufacturability’s enhancement of ship systems pipeline at the designing stage. The analysis of arrangements and possibilities for compensation of deviations for pipeline routes has been carried out. The task was set to produce the “fit pipe” together with the rest of the pipes in the route. It was proposed to compensate for deviations by movement of the pipeline route during pipe installation and to calculate maximum values of these displacements in the analyzed path. Theoretical bases of deviation compensation for pipeline routes using rotations of parallel section pairs of pipes are assembled. Mathematical and graphical simulations of compensation area capacities of pipeline routes with various configurations are completed. Prerequisites have been created for creating an automated program that will allow one to determine values of the compensatory capacities area for pipeline routes and to assign quantities of necessary allowances.

2016-01-01

As part of an ongoing research program with undergraduate students at Florida Gulf Coast University, we have constructed an aperture photometry pipeline for K2 data. The pipeline performs dynamic automated aperture mask definition for all targets in the K2 fields, followed by aperture photometry and detrending. Our pipeline is currently used to support a number of projects, including studies of stellar rotation and activity, red giant asteroseismology, gyrochronology, and exoplanet searches. In addition, output is used to support an undergraduate class on exoplanets aimed at a student audience of both majors and non-majors. The pipeline is designed for both batch and single-target use, and is easily extensible to data from other missions, and pipeline output is available to the community. This paper will describe our pipeline and its capabilities and illustrate the quality of the results, drawing on all of the applications for which it is currently used.

These challenges and opportunities are partially a result of the increasingly competitive nature of pipeline development and the public`s intolerance to incidentsmore » of pipeline failure. A creative systems approach to these challenges is often the key to the project moving ahead. This usually encompasses collaboration among users of the pipeline, pipeline owners and operators, international engineering and construction companies, equipment and materials suppliers, in-country engineers and constructors, international lending agencies and financial institutions.« less

The Student Educational Enrichment Programs at the Medical College of Georgia in the School of Medicine were created to increase underrepresented minorities in the pipeline to biomedical science careers. Eight-week summer programs are conducted for high school, research apprentice, and intermediate and advanced college students. There is a prematriculation program for accepted medical, dental, and graduate students. Between 1979 and 1990, 245 high school students attended 12 summer programs. Of these, 240 (98%) entered college 1 year later. In 1986, after eight programs, 162 (68%) high school participants graduated from college with a baccalaureate degree, and 127 responded to a follow-up survey. Sixty-two (49%) of the college graduates attended health science schools, and 23 (18%) of these matriculated to medical school. Of college students, 504 participated in 13 summer programs. Four hundred (79%) of these students responded to a questionnaire, which indicated that 348 (87%) of the 400 entered health science occupations and/or professional schools; 179 (45%) of these students matriculated to medical school. Minority students participating in enrichment programs have greater success in gaining acceptance to college and professional school. These data suggest that early enrichment initiatives increase the number of underrepresented minorities in the biomedical science pipeline.

Image classification is a prerequisite for copy quality enhancement in all-in-one (AIO) device that comprises a printer and scanner, and which can be used to scan, copy and print. Different processing pipelines are provided in an AIO printer. Each of the processing pipelines is designed specifically for one type of input image to achieve the optimal output image quality. A typical approach to this problem is to apply Support Vector Machine to classify the input image and feed it to its corresponding processing pipeline. The online training SVM can help users to improve the performance of classification as input images accumulate. At the same time, we want to make quick decision on the input image to speed up the classification which means sometimes the AIO device does not need to scan the entire image to make a final decision. These two constraints, online SVM and quick decision, raise questions regarding: 1) what features are suitable for classification; 2) how we should control the decision boundary in online SVM training. This paper will discuss the compatibility of online SVM and quick decision capability.

1996-12-31

A novel application for the detection of airborne hydrocarbons has been successfully developed by means of a highly sensitive, fast responding Flame Ionization Detector (FID). The traditional way to monitor pipeline leaks has been by ground crews using specific sensors or by airborne crews highly trained to observe anomalies associated with leaks during periodic surveys of the pipeline right-of-way. The goal has been to detect leaks in a fast and cost effective way before the associated spill becomes a costly and hazardous problem. This paper describes a leak detection system combined with a global positioning system (GPS) and a computerizedmore » data output designed to pinpoint the presence of hydrocarbons in the air space of the pipeline`s right of way. Fixed wing aircraft as well as helicopters have been successfully used as airborne platforms. Natural gas, crude oil and finished products pipelines in Canada and the US have been surveyed using this technology with excellent correlation between the aircraft detection and in situ ground detection. The information obtained is processed with a proprietary software and reduced to simple coordinates. Results are transferred to ground crews to effect the necessary repairs.« less

Rescuing the physician-scientist workforce: the time for action is now.

PubMed

Milewicz, Dianna M; Lorenz, Robin G; Dermody, Terence S; Brass, Lawrence F

2015-10-01

The 2014 NIH Physician-Scientist Workforce (PSW) Working Group report identified distressing trends among the small proportion of physicians who consider research to be their primary occupation. If unchecked, these trends will lead to a steep decline in the size of the workforce. They include high rates of attrition among young investigators, failure to maintain a robust and diverse pipeline, and a marked increase in the average age of physician-scientists, as older investigators have chosen to continue working and too few younger investigators have entered the workforce to replace them when they eventually retire. While the policy debates continue, here we propose four actions that can be implemented now. These include applying lessons from the MD-PhD training experience to postgraduate training, shortening the time to independence by at least 5 years, achieving greater diversity and numbers in training programs, and establishing Physician-Scientist Career Development offices at medical centers and universities. Rather than waiting for the federal government to solve our problems, we urge the academic community to address these goals by partnering with the NIH and national clinical specialty and medical organizations.

Channel erosion surveys along the TAPS route, Alaska, 1977

USGS Publications Warehouse

Loeffler, Robert M.; Childers, Joseph M.

1977-01-01

Channel surveys were made along the trans-Alaska pipeline system (TAPS) route during 1977 at the same 28 sites that were studied in 1976. In addition, a new site at pipeline mile 22 near Deadhorse (alignment No 134) along the Sagavanirktok River was put under surveillance. Except for changes wrought by the completion of construction, most of the sites showed very little change. Significant events include virtual completion of all construction activities along the pipeline, the pipeline startup , and the breakup flood along the Sagavanirktok River which breached many river-training structures. In general, 1977 saw heavy flooding on streams draining the north and south slopes of the Brooks Range and only moderate flooding on streams further south. Aerial photogrammetric surveys were used again in 1977 on the same seven sites as in 1976. Results document the applicability of the method for channel erosion studies. (Woodard-USGS)

Snorkel: Rapid Training Data Creation with Weak Supervision.

Labeling training data is increasingly the largest bottleneck in deploying machine learning systems. We present Snorkel, a first-of-its-kind system that enables users to train state-of- the-art models without hand labeling any training data. Instead, users write labeling functions that express arbitrary heuristics, which can have unknown accuracies and correlations. Snorkel denoises their outputs without access to ground truth by incorporating the first end-to-end implementation of our recently proposed machine learning paradigm, data programming. We present a flexible interface layer for writing labeling functions based on our experience over the past year collaborating with companies, agencies, and research labs. In a user study, subject matter experts build models 2.8× faster and increase predictive performance an average 45.5% versus seven hours of hand labeling. We study the modeling tradeoffs in this new setting and propose an optimizer for automating tradeoff decisions that gives up to 1.8× speedup per pipeline execution. In two collaborations, with the U.S. Department of Veterans Affairs and the U.S. Food and Drug Administration, and on four open-source text and image data sets representative of other deployments, Snorkel provides 132% average improvements to predictive performance over prior heuristic approaches and comes within an average 3.60% of the predictive performance of large hand-curated training sets.

Reusable, extensible, and modifiable R scripts and Kepler workflows for comprehensive single set ChIP-seq analysis.

PubMed

Cormier, Nathan; Kolisnik, Tyler; Bieda, Mark

2016-07-05

There has been an enormous expansion of use of chromatin immunoprecipitation followed by sequencing (ChIP-seq) technologies. Analysis of large-scale ChIP-seq datasets involves a complex series of steps and production of several specialized graphical outputs. A number of systems have emphasized custom development of ChIP-seq pipelines. These systems are primarily based on custom programming of a single, complex pipeline or supply libraries of modules and do not produce the full range of outputs commonly produced for ChIP-seq datasets. It is desirable to have more comprehensive pipelines, in particular ones addressing common metadata tasks, such as pathway analysis, and pipelines producing standard complex graphical outputs. It is advantageous if these are highly modular systems, available as both turnkey pipelines and individual modules, that are easily comprehensible, modifiable and extensible to allow rapid alteration in response to new analysis developments in this growing area. Furthermore, it is advantageous if these pipelines allow data provenance tracking. We present a set of 20 ChIP-seq analysis software modules implemented in the Kepler workflow system; most (18/20) were also implemented as standalone, fully functional R scripts. The set consists of four full turnkey pipelines and 16 component modules. The turnkey pipelines in Kepler allow data provenance tracking. Implementation emphasized use of common R packages and widely-used external tools (e.g., MACS for peak finding), along with custom programming. This software presents comprehensive solutions and easily repurposed code blocks for ChIP-seq analysis and pipeline creation. Tasks include mapping raw reads, peakfinding via MACS, summary statistics, peak location statistics, summary plots centered on the transcription start site (TSS), gene ontology, pathway analysis, and de novo motif finding, among others. These pipelines range from those performing a single task to those performing full analyses of ChIP-seq data. The pipelines are supplied as both Kepler workflows, which allow data provenance tracking, and, in the majority of cases, as standalone R scripts. These pipelines are designed for ease of modification and repurposing.

The Relationship Between Cognitive and Non-Cognitive Variables and Academic Performance of Students in the Science Enrichment Preparation (S.E.P.) Program

NASA Astrophysics Data System (ADS)

Borden, Paula D.

This dissertation study concerned the lack of underrepresented minority students matriculating through the health professions pipeline. The term pipeline is "the educational avenue by which one must travel to successfully enter a profession" (Sullivan Alliance, 2004). There are a significant number of health professional pipeline programs based across the United States and, for the purposes of this study, a focus was placed on the Science Enrichment Preparation (S.E.P.) Program which is based at The University of North Carolina at Chapel Hill. The S.E.P. Program, is an eight-week residential summer experience, designed to support underrepresented minority pre-health students develop the competitive edge for successful admission into health professional school programs. The bedrock of this dissertation study concerned itself with the relationships between cognitive variables and non-cognitive variables and academic performance of students in the S.E.P. Program from 2005-2013. The study was undertaken to provide a clearer understanding for the NC Health Careers Access Program's (NC-HCAP) leadership with regard to variables associated with the students' academic performance in the S.E.P. Program. The data outcomes were informative for NC-HCAP in identifying cognitive and non-cognitive variables associated with student academic performance. Additionally, these findings provided direction as to what infrastructures may be put into place to more effectively support the S.E.P. participants. It is the researcher's hope this study may serve as an educational model and resource to pipeline programs and others with similar educational missions. The consequences and implications of a non-diverse healthcare workforce are high and far reaching. Without parity representation in the healthcare workforce, health disparities between racial and economic groups will likely continue to grow.

By now, all dental schools should understand the need to increase the enrollment of underrepresented minority (URM) students. While there has been a major increase in the number of Hispanic/Latino, African American/Black, and Native American applicants to dental schools over the past decade, there has not been a major percent increase in the enrollment of URM students except in the schools participating in the Pipeline, Profession, and Practice: Community-Based Dental Education program, which have far exceeded the percent increase in enrollment of URM students in other U.S. dental schools during Phase I of the program (2002-07). Assuming that all dental schools wish to improve the diversity of their student bodies, chapters 9-12 of this report--for which this chapter serves as an introduction--provide strategies learned from the Pipeline schools to increase the applications and enrollment of URM students. Some of the changes that the Pipeline schools put into place were the result of two focus group studies of college and dental students of color. These studies provided guidance on some of the barriers and challenges students of color face when considering dentistry as a career. New accreditation standards make it clear that the field of dentistry expects dental schools to re-energize their commitment to diversity.

Feature extration from imagery is an important and long-standing problem in remote sensing. In this paper, we report on work using genetic programming to perform feature extraction simultaneously from multispectral and digital elevation model (DEM) data. The tool used is the GENetic Imagery Exploitation (GENIE) software, which produces image-processing software that inherently combines spatial and spectral processing. GENIE is particularly useful in exploratory studies of imagery, such as one often does in combining data from multiple sources. The user trains the software by painting the feature of interest with a simple graphical user interface. GENIE then uses genetic programming techniquesmore » to produce an image-processing pipeline. Here, we demonstrate evolution of image processing algorithms that extract a range of land-cover features including towns, grasslands, wild fire burn scars, and several types of forest. We use imagery from the DOE/NNSA Multispectral Thermal Imager (MTI) spacecraft, fused with USGS 1:24000 scale DEM data.« less

R(X) for recruitment and retention of veterinarian scientists: money, marketing, mentoring.

PubMed

Freeman, Lisa C

2005-01-01

Veterinary medicine is failing both to sustain its academic base and to meet national needs for research in the fields of comparative medicine (translational research), public health, and food production. The basis for the shortage of veterinarians with research expertise is multi-factorial and related to the substantial commitment of time and money required to obtain both a DVM and advanced training, as well as the lack of motivation among veterinary students to engage in biomedical science. Effective strategies for increasing the number of veterinarian scientists must address these issues using a balanced combination of money, marketing, and mentoring. Success will require not only that we increase and improve opportunities for research training, but also that we create and sustain veterinary college environments that attract, foster, and reward dedication to research. The ''research pipeline'' needs to be transformed into a ''research manifold'' with multiple portals for entry and re-entry of trainees. Age-appropriate educational and mentoring programs should be implemented at K-14, baccalaureate, veterinary college, post-graduate, and junior faculty levels to promote recruitment, training, and retention of veterinarian scientists. New initiatives are especially needed to attract students with primary interests in science and biomedical research to the veterinary profession and to facilitate transition of motivated veterinary graduates from private practice to research careers. Specific examples of such programs are presented and future directions are discussed.

This report describes the community context, concept and mission of The Faculty of Medicine at Memorial University of Newfoundland (Memorial), Canada, and its 'pathways to rural practice' approach, which includes influences at the pre-medical school, medical school experience, postgraduate residency training, and physician practice levels. Memorial's pathways to practice helped Memorial to fulfill its social accountability mandate to populate the province with highly skilled rural generalist practitioners. Programs/interventions/initiatives: The 'pathways to rural practice' include initiatives in four stages: (1) before admission to medical school; (2) during undergraduate medical training (medical degree (MD) program); (3) during postgraduate vocational residency training; and (4) after postgraduate vocational residency training. Memorial's Learners & Locations (L&L) database tracks students through these stages. The Aboriginal initiative - the MedQuest program and the admissions process that considers geographic or minority representation in terms of those selecting candidates and the candidates themselves - occurs before the student is admitted. Once a student starts Memorial's MD program, the student has ample opportunities to have rural-based experiences through pre-clerkship and clerkship, of which some take place exclusively outside of St. John's tertiary hospitals. Memorial's postgraduate (PG) Family Medicine (FM) residency (vocational) training program allows for deeper community integration and longer periods of training within the same community, which increases the likelihood of a physician choosing rural family medicine. After postgraduate training, rural physicians were given many opportunities for professional development as well as faculty development opportunities. Each of the programs and initiatives were assessed through geospatial rurality analysis of administrative data collected upon entry into and during the MD program and PG training (L&L). Among Memorial MD-graduating classes of 2011-2020, 56% spent the majority of their lives before their 18th birthday in a rural location and 44% in an urban location. As of September 2016, 23 Memorial MD students self-identified as Aboriginal, of which 2 (9%) were from an urban location and 20 (91%) were from rural locations. For Year 3 Family Medicine, graduating classes 2011 to 2019, 89% of placement weeks took place in rural communities and 8% took place in rural towns. For Memorial MD graduating classes 2011-2013 who completed Memorial Family Medicine vocational training residencies, (N=49), 100% completed some rural training. For these 49 residents (vocational trainees), the average amount of time spent in rural areas was 52 weeks out of a total average FM training time of 95 weeks. For Family Medicine residencies from July 2011 to October 2016, 29% of all placement weeks took place in rural communities and 21% of all placement weeks took place in rural towns. For 2016-2017 first-year residents, 53% of the first year training is completed in rural locations, reflecting an even greater rural experiential learning focus. Memorial's pathways approach has allowed for the comprehensive training of rural generalists for Newfoundland and Labrador and the rest of Canada and may be applicable to other settings. More challenges remain, requiring ongoing collaboration with governments, medical associations, health authorities, communities, and their physicians to help achieve reliable and feasible healthcare delivery for those living in rural and remote areas.

An Efficient Pipeline for Abdomen Segmentation in CT Images.

PubMed

Koyuncu, Hasan; Ceylan, Rahime; Sivri, Mesut; Erdogan, Hasan

2018-04-01

Computed tomography (CT) scans usually include some disadvantages due to the nature of the imaging procedure, and these handicaps prevent accurate abdomen segmentation. Discontinuous abdomen edges, bed section of CT, patient information, closeness between the edges of the abdomen and CT, poor contrast, and a narrow histogram can be regarded as the most important handicaps that occur in abdominal CT scans. Currently, one or more handicaps can arise and prevent technicians obtaining abdomen images through simple segmentation techniques. In other words, CT scans can include the bed section of CT, a patient's diagnostic information, low-quality abdomen edges, low-level contrast, and narrow histogram, all in one scan. These phenomena constitute a challenge, and an efficient pipeline that is unaffected by handicaps is required. In addition, analysis such as segmentation, feature selection, and classification has meaning for a real-time diagnosis system in cases where the abdomen section is directly used with a specific size. A statistical pipeline is designed in this study that is unaffected by the handicaps mentioned above. Intensity-based approaches, morphological processes, and histogram-based procedures are utilized to design an efficient structure. Performance evaluation is realized in experiments on 58 CT images (16 training, 16 test, and 26 validation) that include the abdomen and one or more disadvantage(s). The first part of the data (16 training images) is used to detect the pipeline's optimum parameters, while the second and third parts are utilized to evaluate and to confirm the segmentation performance. The segmentation results are presented as the means of six performance metrics. Thus, the proposed method achieves remarkable average rates for training/test/validation of 98.95/99.36/99.57% (jaccard), 99.47/99.67/99.79% (dice), 100/99.91/99.91% (sensitivity), 98.47/99.23/99.85% (specificity), 99.38/99.63/99.87% (classification accuracy), and 98.98/99.45/99.66% (precision). In summary, a statistical pipeline performing the task of abdomen segmentation is achieved that is not affected by the disadvantages, and the most detailed abdomen segmentation study is performed for the use before organ and tumor segmentation, feature extraction, and classification.

Repeated site surveys and aerial photographs at 26 stream crossings along the trans-Alaska pipeline system (TAPS) route during the period 1969-74 provide chronologie records of channel changes that predate pipeline-related construction at the sites. The 1974 surveys and photographs show some of the channel changes wrought by construction of the haul road from the Yukon River to Prudhoe Bay and by construction of camps and working pads all along the pipeline route. No pipeline crossings were constructed before 1975. These records of channel changes together with flood and icing measurements are part of the United States Department of the lnterior's continuing surveillance program to document the hydrologic aspects of the trans-Alaska pipeline and its environmental impacts.

The effect of the Advanced Placement Training and Incentive Program on increasing enrollment and performance on Advanced Placement science exams

NASA Astrophysics Data System (ADS)

Ramsey, Susan Brady

The purpose of this study is to examine the effectiveness of the National Math and Science Initiative's Advanced Placement Training and Incentive Program (APTIP) on the number of students taking AP science courses and their performance. The study evaluated 39 schools over a six-year period in six states that participate in the APTIP. The National Math and Science Initiative provided data for cohort I. A general linear model for repeated measures was used to evaluate the data. Data was evaluated three years prior to the intervention and three years during the intervention, which will actually continue for two more years (2012 and 2013) since cohort I schools were awarded five years of support. Students in APTIP schools enrolled in more AP science exams (AP Biology, AP Chemistry, AP Environmental Science, and AP Physics-B) over the course of the intervention. The quantity of students earning qualifying scores increased during the intervention years. APTIP is a multi-tiered program that includes seven days of teacher training, three six-hour student prep sessions, school equipment, reduced exam fees, and monetary incentives for students and teachers. This program positively impacted the quantity of enrollment and qualifying scores during the three years evaluated in this study. Increases in the number of female and African American students' test takers their and qualifying scores were seen in all three years of the APTIP intervention. This study supports the premise that the first step to increasing the Science, technology, engineering, and math (STEM) pipeline is giving access to advanced courses to more students in high schools.

A qualitative inquiry of educational requirements of selected professions in the Oklahoma aerospace industry

Walker, Casey Jerry Kennon

Interview of incumbents of intellectual capital positions at Boeing. The aerospace industry is a dynamic industry that requires continual skill updates to keep up with advancements in technology and operational trends within the industry. The purpose of this study was to examine intellectual capital requirements of selected professional positions within the Boeing Company in Oklahoma. Data obtained through interviews was used to determine if educational skills gaps existed. The findings of the study can be used to develop an aerospace educational pipeline based on collaborative relationships between industry and higher education to facilitate educational and training programs. Three broad research questions were used to address and support the findings of this study related to educational background, career progression, and gaps. A purposive sample of 10 professional positions was selected for interview using an interview guide containing 18 questions. Data was analyzed using manual coding techniques. Findings and conclusions. The study found that minimum education requirements for selected professional positions consisted of a bachelor's degree. Although the majority of participants identified a business degree as optimal, several participants indicated that an education background from multiple disciplines would provide the greatest benefit. Data from interviews showed educational degrees were not specialized enough and skills required to perform job functions were obtained through direct on the job experience or through corporate training. Indications from participant responses showed employees with a thorough knowledge of government acronyms had a decided advantage over those that did not. Recommendations included: expanding the study to multiple organizations by conducting a survey; expanding industry and academic partnerships; establishing a structured educational pipeline to fill critical positions; creating broad aerospace curricula degree programs tailored to industry needs; incorporate additional capstone and internship opportunities to bridge classroom learning and experience; and establish an industry/academic liaison to develop internship opportunities.

Problems of metal flow-accelerated corrosion (FAC) in the pipelines and equipment of the condensate- feeding and wet-steam paths of NPP power-generating units (PGU) are examined. Goals, objectives, and main principles of the methodology for the implementation of an integrated program of AO Concern Rosenergoatom for the prevention of unacceptable FAC thinning and for increasing operational flow-accelerated corrosion resistance of NPP EaP are worded (further the Program). A role is determined and potentialities are shown for the use of Russian software packages in the evaluation and prediction of FAC rate upon solving practical problems for the timely detection of unacceptable FAC thinning in the elements of pipelines and equipment (EaP) of the secondary circuit of NPP PGU. Information is given concerning the structure, properties, and functions of the software systems for plant personnel support in the monitoring and planning of the inservice inspection of FAC thinning elements of pipelines and equipment of the secondary circuit of NPP PGUs, which are created and implemented at some Russian NPPs equipped with VVER-1000, VVER-440, and BN-600 reactors. It is noted that one of the most important practical results of software packages for supporting NPP personnel concerning the issue of flow-accelerated corrosion consists in revealing elements under a hazard of intense local FAC thinning. Examples are given for successful practice at some Russian NPP concerning the use of software systems for supporting the personnel in early detection of secondary-circuit pipeline elements with FAC thinning close to an unacceptable level. Intermediate results of working on the Program are presented and new tasks set in 2012 as a part of the updated program are denoted. The prospects of the developed methods and tools in the scope of the Program measures at the stages of design and construction of NPP PGU are discussed. The main directions of the work on solving the problems of flow-accelerated corrosion of pipelines and equipment in Russian NPP PGU are defined.

Objective The need for innovative methods to promote training, advancement, and retention of clinical and translational investigators in order to build a pipeline of trainees to focus on mental health-relevant research careers is pressing. The specific aim of the Career Development Institute for Psychiatry is to provide the necessary skill set and support to a nationally selected broad-based group of young psychiatrists and PhD researchers to launch and maintain successful research careers in academic psychiatry. The program targets such career skills as writing, negotiating, time management, juggling multiple demanding responsibilities, networking, project management, responsible conduct of research, and career goal setting. The current program builds on the previous program by adding a longitudinal, long-distance, virtual mentoring and training program, seen as integral components to sustaining these career skills. Methods Career development activities occur in four phases over a 24-month period for each annual class of up to 18 participants: online baseline career and skills self-assessment and goal setting, preparations for four-day in-person workshop, long-distance structured mentoring and online continued learning, peer- mentoring activities and post-program career progress and process evaluation. Program instructors and mentors consist of faculty from the University of Pittsburgh and Stanford University as well as successful past program graduates from other universities as peer-mentors. A comprehensive website facilitates long-distance activities to occur on-line. Continued training occurs via webinars every other month by experts discussing topics selected for the needs of each particular class. Personally assigned mentors meet individually bi-monthly with participants via a secure web-based “mentor center” that allows mentor dyads to collaborate, share, review, and discuss career goals and research activities. Results Preliminary results after the first 24 months are favorable. Almost uniformly, participants felt the program was very helpful. They had regular contact with their long-distance mentor at least every two months over the two-year period. At the end of the 2 year period, the majority of participants had full-time faculty appointments with K-award support and very few were doing primarily clinical work. Conclusions The longitudinal program of education, training, mentoring, peer support, and communications for individuals making the transition to academic research should increase the number of scientists committed to research careers in mental health.

Increasing Diversity and Gender Parity by working with Professional Organizations and HBCUs

NASA Astrophysics Data System (ADS)

Wims, T. R.

2017-12-01

Context/Purpose: This abstract proposes tactics for recruiting diverse applicants and addressing gender parity in the geoscience workforce. Methods: The geoscience community should continue to develop and expand a pipeline of qualified potential employees and managers at all levels. Recruitment from professional organizations, which are minority based, such as the National Society of Black Engineers (NSBE), and the Society of Hispanic Professional Engineers (SHPE) provides senior and midlevel scientists, engineers, program managers, and corporate managers/administrators with proven track records of success. Geoscience organizations should consider increasing hiring from the 100+ Historically Black Colleges and Universities (HBCU) which have a proven track records of producing high quality graduates with math, science, computer science, and engineering backgrounds. HBCU alumni have been working in all levels of government and corporate organizations for more than 50 years. Results: Professional organizations, like NSBE, have members with one to 40 years of applicable work experience, who are prime candidates for employment in the geoscience community at all levels. NSBE, also operates pipeline programs to graduate 10,000 bachelor degree minority candidates per year by 2025, up from the current 3,620/year. HBCUs have established educational programs and several pipelines for attracting undergraduate students into the engineering and science fields. Since many HBCUs enroll more women than men, they are also addressing gender parity. Both professional organizations and HBCU's have pipeline programs that reach children in high school. Interpretation: Qualified and capable minority and women candidates are available in the United States. Pipelines for employing senior, mid-level, and junior skill sets are in place, but underutilized by some geoscience companies and organizations.

From leaky pipeline to irrigation system: minority education through the lens of community-based participatory research.

James, Rosalina; Starks, Helene; Segrest, Valerie Ann; Burke, Wylie

2012-01-01

Higher education has long made efforts to increase underrepresented minority participation in biomedical research and health fields. However, relatively few minority trainees complete advanced degrees or proceed to independent research careers, a loss referred to as the "leaky pipeline." Minority trainees may take alternate pathways to climbing the academic ladder, exiting to pursue multiple disciplinary or community-serving roles. The authors propose a model for understanding minority departures from the education pipeline as a basis for supporting careers that align with community goals for health. Concepts of the traditional pipeline training model are compared with a model that aligns with community-based participatory research (CBPR) principles and practices. The article describes an irrigation model that incorporates informal learning from academic and community knowledge bases to prepare trainees for CBPR and interdisciplinary research. Students serve as agents that foster individual, institutional, and social change needed to address health problems while attending to root causes of disparities. Viewing minority students as agents for community engagement allows institutions to reassess the role training can play in diversifying participation in higher education and research. An irrigation model supports development of an infrastructure that optimizes success at all post-secondary levels, and enhances CBPR capacity wherever trainees live, work, and learn. Linking formal education to informal learning in context of CBPR experiences can also reduce community mistrust of research while nurturing productive research partnerships with communities to address health disparities.

Migraineurs show an increased load of white matter hyperintensities (WMHs) and more rapid deep WMH progression. Previous methods for WMH segmentation have limited efficacy to detect small deep WMHs. We developed a new fully automated detection pipeline, DEWS (DEep White matter hyperintensity Segmentation framework), for small and superficially-located deep WMHs. A total of 148 non-elderly subjects with migraine were included in this study. The pipeline consists of three components: 1) white matter (WM) extraction, 2) WMH detection, and 3) false positive reduction. In WM extraction, we adjusted the WM mask to re-assign misclassified WMHs back to WM using many sequential low-level image processing steps. In WMH detection, the potential WMH clusters were detected using an intensity based threshold and region growing approach. For false positive reduction, the detected WMH clusters were classified into final WMHs and non-WMHs using the random forest (RF) classifier. Size, texture, and multi-scale deep features were used to train the RF classifier. DEWS successfully detected small deep WMHs with a high positive predictive value (PPV) of 0.98 and true positive rate (TPR) of 0.70 in the training and test sets. Similar performance of PPV (0.96) and TPR (0.68) was attained in the validation set. DEWS showed a superior performance in comparison with other methods. Our proposed pipeline is freely available online to help the research community in quantifying deep WMHs in non-elderly adults.

A Primer on High-Throughput Computing for Genomic Selection

High-throughput computing (HTC) uses computer clusters to solve advanced computational problems, with the goal of accomplishing high-throughput over relatively long periods of time. In genomic selection, for example, a set of markers covering the entire genome is used to train a model based on known data, and the resulting model is used to predict the genetic merit of selection candidates. Sophisticated models are very computationally demanding and, with several traits to be evaluated sequentially, computing time is long, and output is low. In this paper, we present scenarios and basic principles of how HTC can be used in genomic selection, implemented using various techniques from simple batch processing to pipelining in distributed computer clusters. Various scripting languages, such as shell scripting, Perl, and R, are also very useful to devise pipelines. By pipelining, we can reduce total computing time and consequently increase throughput. In comparison to the traditional data processing pipeline residing on the central processors, performing general-purpose computation on a graphics processing unit provide a new-generation approach to massive parallel computing in genomic selection. While the concept of HTC may still be new to many researchers in animal breeding, plant breeding, and genetics, HTC infrastructures have already been built in many institutions, such as the University of Wisconsin–Madison, which can be leveraged for genomic selection, in terms of central processing unit capacity, network connectivity, storage availability, and middleware connectivity. Exploring existing HTC infrastructures as well as general-purpose computing environments will further expand our capability to meet increasing computing demands posed by unprecedented genomic data that we have today. We anticipate that HTC will impact genomic selection via better statistical models, faster solutions, and more competitive products (e.g., from design of marker panels to realized genetic gain). Eventually, HTC may change our view of data analysis as well as decision-making in the post-genomic era of selection programs in animals and plants, or in the study of complex diseases in humans.

Labeling training data is increasingly the largest bottleneck in deploying machine learning systems. We present Snorkel, a first-of-its-kind system that enables users to train state-of- the-art models without hand labeling any training data. Instead, users write labeling functions that express arbitrary heuristics, which can have unknown accuracies and correlations. Snorkel denoises their outputs without access to ground truth by incorporating the first end-to-end implementation of our recently proposed machine learning paradigm, data programming. We present a flexible interface layer for writing labeling functions based on our experience over the past year collaborating with companies, agencies, and research labs. In a user study, subject matter experts build models 2.8× faster and increase predictive performance an average 45.5% versus seven hours of hand labeling. We study the modeling tradeoffs in this new setting and propose an optimizer for automating tradeoff decisions that gives up to 1.8× speedup per pipeline execution. In two collaborations, with the U.S. Department of Veterans Affairs and the U.S. Food and Drug Administration, and on four open-source text and image data sets representative of other deployments, Snorkel provides 132% average improvements to predictive performance over prior heuristic approaches and comes within an average 3.60% of the predictive performance of large hand-curated training sets.

Pipeline corridors through wetlands - impacts on plant communities: Bayou Pointe Aux Chenes, Terrebonne Parish, Louisiana. Topical report, August 1991--April 1994

Van Dyke, G.D.; Shem, L.M.; Zimmerman, R.E.

1994-12-01

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and night- of-way management practices. This report presents the results of a survey conducted on August 22, 1991, in an emergent intertidal estuarine wetland in Terrebonne Parish, Louisiana. The site includes three pipelines installed between 1958 and 1969. Vegetation within the site comprises three native tidal marsh grasses: Spartina alterniflora, Spartina patens, and Distichlismore » spicata. All three species occurred over the pipelines, within the right-of-way and in both natural areas. Vegetative differences attributable to the installation or presence of the pipelines were not obvious over the pipelines or in the habitat east of the pipelines. However, because of the presence of a canal west of the 1969 pipeline, vegetation was less abundant in that area, and D. spicata was absent from all but the most distant plots of the transacts. Data obtained in the study indicate that when rights-of-way through brackish marsh are restored to their original elevations, they are revegetated with native vegetation similar to that in surrounding areas.« less

Dispersion of odorants in natural gas distribution networks

Gross, R.; Fontana, E.; Silva, A.; Quadri, M. B.; Souza, S. M. A. G. U.

2018-03-01

A numerical modeling analysis of a pulse train diffusion, representing an odorant injection in a natural gas pipeline, was carried out and compared with experimental data from a real pipeline. The main purpose of this study is to evaluate how the odorant dispersion occurs along the pipe. Due to technical limitations, the odorant is injected in the line as a pulse and it is important to find out the point in the pipeline where the oscillating concentration of odorant fits into a range of values that meet both the legislation and the interests of customers who may have the quality of their products affected by this oscillation. Since the natural gas pipelines do not have strong streamline curvatures and the flow is always turbulent, it is relatively easy to determine the velocity and concentration fields using the Computational Fluid Dynamics techniques. In this study the RANS (Reynolds Average Navier-Stokes) equations with the k - ɛ turbulence model was used to build the mathematical model. Comparisons of the experimental data and numerical results show a strong agreement for the studied cases. Based on the results, it was possible to know the minimum and maximum values of odorant concentration along the pipelines.

SVD/MCMC Data Analysis Pipeline for Global Redshifted 21-cm Spectrum Observations of the Cosmic Dawn and Dark Ages

NASA Astrophysics Data System (ADS)

Burns, Jack O.; Tauscher, Keith; Rapetti, David; Mirocha, Jordan; Switzer, Eric

2018-01-01

We have designed a complete data analysis pipeline for constraining Cosmic Dawn physics using sky-averaged spectra in the VHF range (40-200 MHz) obtained either from the ground (e.g., the Experiment to Detect Global Epoch of Reionization Signal, EDGES; and the Cosmic Twilight Polarimeter, CTP) or from orbit above the lunar farside (e.g., the Dark Ages Radio Explorer, DARE). In the case of DARE, we avoid Earth-based RFI, ionospheric effects, and radio solar emissions (when observing at night). To extract the 21-cm spectrum, we parametrize the cosmological signal and systematics with two separate sets of modes defined through Singular Value Decomposition (SVD) of training set curves. The training set for the 21-cm spin-flip brightness temperatures is composed of theoretical models of the first stars, galaxies and black holes created by varying physical parameters within the ares code. The systematics training set is created using sky and beam data to model the beam-weighted foregrounds (which are about four orders of magnitude larger than the signal) as well as expected lab data to model receiver systematics. To constrain physical parameters determining the 21-cm spectrum, we apply to the extracted signal a series of consecutive fitting techniques including two usages of a Markov Chain Monte Carlo (MCMC) algorithm. Importantly, our pipeline efficiently utilizes the significant differences between the foreground and the 21-cm signal in spatial and spectral variations. In addition, it incorporates for the first time polarization data, dramatically improving the constraining power. We are currently validating this end-to-end pipeline using detailed simulations of the signal, foregrounds and instruments.

NASA’s Kepler Space Telescope monitored the photometric variations of over 170,000 stars, at half-hour cadence, over its four-year prime mission. The Kepler pipeline calibrates the pixels of the target apertures for each star, produces light curves with simple aperture photometry, corrects for systematic error, and detects threshold-crossing events (TCEs) that may be due to transiting planets. The pipeline estimates planet parameters for all TCEs and computes diagnostics used by the Threshold Crossing Event Review Team (TCERT) to produce a catalog of objects that are deemed either likely transiting planet candidates or false positives.We created a training set from the Q1-Q12 and Q1-Q16 TCERT catalogs and an ensemble of synthetic transiting planets that were injected at the pixel level into all 17 quarters of data, and used it to train a random forest classifier. The classifier uniformly and consistently applies diagnostics developed by the Transiting Planet Search and Data Validation pipeline components and by TCERT to produce a robust catalog of planet candidates.The characteristics of the planet candidates detected by Kepler (planet radius and period) do not reflect the intrinsic planet population. Detection efficiency is a function of SNR, so the set of detected planet candidates is incomplete. Transit detection preferentially finds close-in planets with nearly edge-on orbits and misses planets whose orbital geometry precludes transits. Reliability of the planet candidates must also be considered, as they may be false positives. Errors in detected planet radius and in assumed star properties can also bias inference of intrinsic planet population characteristics.In this work we infer the intrinsic planet population, starting with the catalog of detected planet candidates produced by our random forest classifier, and accounting for detection biases and reliabilities as well as for radius errors in the detected population.Kepler was selected as the 10th mission of the Discovery Program.

Programming the Navier-Stokes computer: An abstract machine model and a visual editor

NASA Technical Reports Server (NTRS)

Middleton, David; Crockett, Tom; Tomboulian, Sherry

1988-01-01

The Navier-Stokes computer is a parallel computer designed to solve Computational Fluid Dynamics problems. Each processor contains several floating point units which can be configured under program control to implement a vector pipeline with several inputs and outputs. Since the development of an effective compiler for this computer appears to be very difficult, machine level programming seems necessary and support tools for this process have been studied. These support tools are organized into a graphical program editor. A programming process is described by which appropriate computations may be efficiently implemented on the Navier-Stokes computer. The graphical editor would support this programming process, verifying various programmer choices for correctness and deducing values such as pipeline delays and network configurations. Step by step details are provided and demonstrated with two example programs.

Control cells (masters) and computation cells (slaves) are mixed in regular geometric patterns to form reconfigurable arrays known as master-slave mixed arrays (MSMAS). Interconnections of the corners and edges of the hexagonal control cells and the edges of the hexagonal computation cells are used to construct synchronous and asynchronous communication networks, which support local computation and local communication. Data-driven computations result in self-directed ring pipelines within the MSMA, and composite data-flow computations are executed in a pipelined fashion. By viewing an MSMA as a computing network of tightly-linked ring pipelines, data-flow programs can be uniformly distributed over these pipelines formore » efficient resource utilisation. 9 references.« less

2013-01-01

Global health innovators must navigate substantial complexities to successfully develop, implement and sustain global health innovations with impact through application of an Integrated Innovation™ approach. We sought to examine the nature of the literature and evidence around mentoring, training and support of global health innovators. We conducted a scoping review searching eight databases with terms capturing different kinds of innovation and support. Assessment of relevance and mapping was completed by two reviewers, with interpretation by the review team. Twenty-eight relevant papers provided perspectives on fostering global health innovators and innovation. Fifteen included empirical data on supports to global health innovators involving a wide range of innovators. Eight included documentation of outcomes but without designs to determine effectiveness. The diverse mentoring, training and support activities included: business incubators, support organizations and centres for entrepreneurship, technology transfer and intellectual property management, internship programs for business skill development, initiatives to bridge industry and researchers, and platforms for South-led innovation for global health. We propose the cultivation of a pipeline of global health innovators to increase the number of appropriate, sustainable innovations with impact in global health. Further empirical work on how to effectively support global health innovators is needed. PMID:23985118

Reiser, Catherine; LeRoy, Bonnie; Grubs, Robin; Walton, Carol

2015-10-01

The master's degree is the required entry-level degree for the genetic counseling profession in the US and Canada. In 2012 the Association of Genetic Counseling Program Directors (AGCPD) passed resolutions supporting retention of the master's as the entry-level and terminal degree and opposing introduction of an entry-level clinical doctorate (CD) degree. An AGCPD workgroup surveyed directors of all 34 accredited training programs with the objective of providing the Genetic Counseling Advanced Degrees Task Force (GCADTF) with information regarding potential challenges if master's programs were required to transition to an entry-level CD. Program demographics, projected ability to transition to an entry-level CD, factors influencing ability to transition, and potential effects of transition on programs, students and the genetic counseling workforce were characterized. Two programs would definitely be able to transition, four programs would close, thirteen programs would be at risk to close and fourteen programs would probably be able to transition with varying degrees of difficulty. The most frequently cited limiting factors were economic, stress on clinical sites, and administrative approval of a new degree/program. Student enrollment under an entry-level CD model was projected to decrease by 26.2 %, negatively impacting the workforce pipeline. The results further illuminate and justify AGCPD's position to maintain the master's as the entry-level degree.

The general goal of this project was to create a College Biotechnology Program; specific goals of the project were to a) design curricula/courses to prepare students to become entry-level lab technicians, b) redesign and equip lab space to better suit the needs of the program, c) develop partnerships with the local industry through outreach and the formation on an advisory board, d) recruit students into the program, and e) provide instructional support for localmore » high school teachers. At the end of the grant period, NOVA has successfully created two new curricula in biotechnology: an Associate of Applied Science (A.A.S.) in Biotechnology (initiated in Fall 2008) and a Career Studies Certificate for Biotechnology Lab Technicians (to be initiated in Fall 2010). These curricula were designed with advice from an external advisory committee which is comprised of representatives from industry, transfer institutions and high school administrators. To date, almost all courses have been designed and piloted; the equipment needed for the courses and the initial supplies were paid for by the grant as was the re-modeling of some lab space to be used for the biotech courses. In order to market the program, the NOVA Biotech Program has also established relationships with the local high schools. Presentations were given at several local high schools and on-site workshops were held for high school students and teachers. As a result, close to 1000 students have attended program open houses, presentations within the high schools, or workshops held in the summer. Over 100 teachers have received information and/or training in biotechnology. These outreach efforts as well as high quality curricula have started to attract a number of students to the program – for example, there are currently 70 students enrolled in the A.A.S. program. The first students in the biotech program are expected to graduate in Spring 2011; already, students enrolled in the biotech program/courses have obtained jobs or internships in several local companies. Our current goal continues to be to foster the formation of a regional biotech education pipeline into the local industry which includes the recruitment of individuals into the NOVA Biotech Program, the training and graduation of highly-skilled lab technicians, and the placement of graduates in local biotech industry jobs.« less

Medical schools may find implementing pipeline programs for minority pre-medical students prohibitive due to a number of factors including the lack of well-described programs in the literature, the limited evidence for program development, and institutional financial barriers. Our goals were to (1) design a pipeline program based on educational theory; (2) deliver the program in a low cost, sustainable manner; and (3) evaluate intermediate outcomes of the program. SEALS is a 6-week program based on an asset bundles model designed to promote: (1) socialization and professionalism, (2) education in science learning tools, (3) acquisition of finance literacy, (4) the leveraging of mentorship and networks, and (5) social expectations and resilience, among minority pre-medical students. This is a prospective mixed methods study. Students completed survey instruments pre-program, post-program, and 6 months post-program, establishing intermediate outcome measures. Thirteen students matriculated to SEALS. The SEALS cohort rated themselves as improved or significantly improved when asked to rate their familiarity with MCAT components (p < 0.01), ability to ask for a letter of recommendation (p = 0.04), and importance of interview skills (p = 0.04) compared with before the program. Over 90 % of students referenced the health disparities lecture series as an inspiration to advocate for minority health. Six-month surveys suggested that SEALS students acquired and applied four of the five assets at their college campuses. This low-cost, high-quality, program can be undertaken by medical schools interested in promoting a diverse workforce that may ultimately begin to address and reduce health care disparities.

The 'rural pipeline' and retention of rural health professionals in Europe's northern peripheries.

Carson, Dean B; Schoo, Adrian; Berggren, Peter

2015-12-01

The major advance in informing rural workforce policy internationally over the past 25 years has been the recognition of the importance of the 'rural pipeline'. The rural pipeline suggests that people with 'rural origin' (who spent some childhood years in rural areas) and/or 'rural exposure' (who do part of their professional training in rural areas) are more likely to select rural work locations. What is not known is whether the rural pipeline also increases the length of time professionals spend in rural practice throughout their careers. This paper analyses data from a survey of rural health professionals in six countries in the northern periphery of Europe in 2013 to examine the relationship between rural origin and rural exposure and the intention to remain in the current rural job or to preference rural jobs in future. Results are compared between countries, between different types of rural areas (based on accessibility to urban centres), different occupations and workers at different stages of their careers. The research concludes that overall the pipeline does impact on retention, and that both rural origin and rural exposure make a contribution. However, the relationship is not strong in all contexts, and health workforce policy should recognise that retention may in some cases be improved by recruiting beyond the pipeline.

The Computer Science, Biology, and Biomedical Informatics (CoSBBI) program was initiated in 2011 to expose the critical role of informatics in biomedicine to talented high school students.[1] By involving them in Science, Technology, Engineering, and Math (STEM) training at the high school level and providing mentorship and research opportunities throughout the formative years of their education, CoSBBI creates a research infrastructure designed to develop young informaticians. Our central premise is that the trajectory necessary to be an expert in the emerging fields of biomedical informatics and pathology informatics requires accelerated learning at an early age.In our 4(th) year of CoSBBI as a part of the University of Pittsburgh Cancer Institute (UPCI) Academy (http://www.upci.upmc.edu/summeracademy/), and our 2nd year of CoSBBI as an independent informatics-based academy, we enhanced our classroom curriculum, added hands-on computer science instruction, and expanded research projects to include clinical informatics. We also conducted a qualitative evaluation of the program to identify areas that need improvement in order to achieve our goal of creating a pipeline of exceptionally well-trained applicants for both the disciplines of pathology informatics and biomedical informatics in the era of big data and personalized medicine.

2017-08-01

Processing of next-generation sequencing (NGS) data requires significant technical skills, involving installation, configuration, and execution of bioinformatics data pipelines, in addition to specialized postanalysis visualization and data mining software. In order to address some of these challenges, developers have leveraged virtualization containers toward seamless deployment of preconfigured bioinformatics software and pipelines on any computational platform. We present an approach for abstracting the complex data operations of multistep, bioinformatics pipelines for NGS data analysis. As examples, we have deployed 2 pipelines for RNA sequencing and chromatin immunoprecipitation sequencing, preconfigured within Docker virtualization containers we call Bio-Docklets. Each Bio-Docklet exposes a single data input and output endpoint and from a user perspective, running the pipelines as simply as running a single bioinformatics tool. This is achieved using a "meta-script" that automatically starts the Bio-Docklets and controls the pipeline execution through the BioBlend software library and the Galaxy Application Programming Interface. The pipeline output is postprocessed by integration with the Visual Omics Explorer framework, providing interactive data visualizations that users can access through a web browser. Our goal is to enable easy access to NGS data analysis pipelines for nonbioinformatics experts on any computing environment, whether a laboratory workstation, university computer cluster, or a cloud service provider. Beyond end users, the Bio-Docklets also enables developers to programmatically deploy and run a large number of pipeline instances for concurrent analysis of multiple datasets. © The Authors 2017.

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents results of a survey conducted over the period of August 5--7, 1991, at the Little Timber Creek crossing in Gloucester County, New Jersey, where three pipelines, constructed in 1950, 1960, and 1990, cross the creek and associated wetlands. The old side of the ROW, created bymore » the installation of the 1960 pipeline, was designed to contain a raised peat bed over the 1950 pipeline and an open-water ditch over the 1960 pipeline. The new portion of the ROW, created by installation of the 1990 pipeline, has an open-water ditch over the pipeline (resulting from settling of the backfill) and a raised peat bed (resulting from rebound of compacted peat). Both the old and new ROWs contain dense stands of herbs; the vegetation on the old ROW was more similar to that in the adjacent natural area than was vegetation in the new ROW. The ROW increased species and habitat diversity in the wetlands. It may contribute to the spread of purple loosestrife and affect species sensitive to habitat fragmentation.« less

Genome annotation is a primary step in genomic research. To establish a light and portable prokaryotic genome annotation pipeline for use in individual laboratories, we developed a Shiny app package designated as "P-CAPS" (Prokaryotic Contig Annotation Pipeline Server). The package is composed of R and Python scripts that integrate publicly available annotation programs into a server application. P-CAPS is not only a browser-based interactive application but also a distributable Shiny app package that can be installed on any personal computer. The final annotation is provided in various standard formats and is summarized in an R markdown document. Annotation can be visualized and examined with a public genome browser. A benchmark test showed that the annotation quality and completeness of P-CAPS were reliable and compatible with those of currently available public pipelines.

Partitioning problems in parallel, pipelined and distributed computing

NASA Technical Reports Server (NTRS)

Bokhari, S.

1985-01-01

The problem of optimally assigning the modules of a parallel program over the processors of a multiple computer system is addressed. A Sum-Bottleneck path algorithm is developed that permits the efficient solution of many variants of this problem under some constraints on the structure of the partitions. In particular, the following problems are solved optimally for a single-host, multiple satellite system: partitioning multiple chain structured parallel programs, multiple arbitrarily structured serial programs and single tree structured parallel programs. In addition, the problems of partitioning chain structured parallel programs across chain connected systems and across shared memory (or shared bus) systems are also solved under certain constraints. All solutions for parallel programs are equally applicable to pipelined programs. These results extend prior research in this area by explicitly taking concurrency into account and permit the efficient utilization of multiple computer architectures for a wide range of problems of practical interest.

Remedial Investigation Report on the Abandoned Nitric Acid Pipeline at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee. Energy Systems Environmental Restoration Program; Y-12 Environmental Restoration Program

Upper East Fork Poplar Creek Operable Unit 2 consists of the Abandoned Nitric Acid pipeline (ANAP). This pipeline was installed in 1951 to transport liquid wastes {approximately}4800 ft from Buildings 9212, 9215, and 9206 to the S-3 Ponds. Materials known to have been discharged through the pipeline include nitric acid, depleted and enriched uranium, various metal nitrates, salts, and lead skimmings. During the mid-1980s, sections of the pipeline were removed during various construction projects. A total of 19 locations were chosen to be investigated along the pipeline for the first phase of this Remedial Investigation. Sampling consisted of drilling downmore » to obtain a soil sample at a depth immediately below the pipeline. Additional samples were obtained deeper in the subsurface depending upon the depth of the pipeline, the depth of the water table, and the point of auger refusal. The 19 samples collected below the pipeline were analyzed by the Oak Ridge Y-12 Plant`s laboratory for metals, nitrate/nitrite, and isotopic uranium. Samples collected from three boreholes were also analyzed for volatile organic compounds because these samples produced a response with organic vapor monitoring equipment. Uranium activities in the soil samples ranged from 0.53 to 13.0 pCi/g for {sup 238}U, from 0.075 to 0.75 pCi/g for {sup 235}U, and from 0.71 to 5.0 pCi/g for {sup 238}U. Maximum total values for lead, chromium, and nickel were 75.1 mg/kg, 56.3 mg/kg, and 53.0 mg/kg, respectively. The maximum nitrate/nitrite value detected was 32.0 mg-N/kg. One sample obtained adjacent to a sewer line contained various organic compounds, at least some of which were tentatively identified as fragrance chemicals commonly associated with soaps and cleaning solutions. The results of the baseline human health risk assessment for the ANAP contaminants of potential concern show no unacceptable risks to human health.« less

Despite attempts to increase enrollment of under-represented minorities (URMs: primarily Black/African American, Hispanic/Latino, and Native American students) in health professional programs, limited progress has been made. Compelling reasons to rectify this situation include equity for URMs, better prepared health professionals when programs are diverse, better quality and access to health care for UMR populations, and the need for diverse talent to tackle difficult questions in health science and health care delivery. However, many students who initiate traditional "pipeline" programs designed to link URMs to professional schools in health professions and the sciences, do not complete them. In addition, program requirements often restrict entry to highly qualified students while not expanding opportunities for promising, but potentially less well-prepared candidates. The current study describes innovations in an undergraduate pipeline program, the Health Equity Scholars Program (HESP) designed to address barriers URMs experience in more traditional programs, and provides evaluative outcomes and qualitative feedback from participants. A primary outcome was timely college graduation. Eighty percent (80%) of participants, both transfer students and first time students, so far achieved this outcome, with 91% on track, compared to the campus average of 42% for all first time students and 58-67% for transfers. Grade point averages also improved (p = 0.056) after program participation. Graduates (94%) were working in health care/human services positions and three were in health-related graduate programs. Creating a more flexible program that admits a broader range of URMs has potential to expand the numbers of URM students interested and prepared to make a contribution to health equity research and clinical care.

The National Astronomy Consortium (NAC) is a program led by the National Radio Astronomy Observatory (NRAO) and Associated Universities Inc., (AUI) in partnership with the National Society of Black Physicists (NSBP), and a number of minority and majority universities to increase the numbers of students from underrepresented groups and those otherwise overlooked by the traditional academic pipeline into STEM or STEM-related careers. The seed for the NAC was a partnership between NRAO and Howard University which began with an exchange of a few summer students five years ago. Since then the NAC has grown tremendously. Today the NAC aims to host between 4 to 5 cohorts nationally in an innovative model in which the students are mentored throughout the year with multiple mentors and peer mentoring, continued engagement in research and professional development / career training throughout the academic year and throughout their careers. We will summarize the results from this innovative and highly succesful program and provide lessons learned.

Adaptation of a program for nonlinear finite element analysis to the CDC STAR 100 computer

NASA Technical Reports Server (NTRS)

Pifko, A. B.; Ogilvie, P. L.

1978-01-01

The conversion of a nonlinear finite element program to the CDC STAR 100 pipeline computer is discussed. The program called DYCAST was developed for the crash simulation of structures. Initial results with the STAR 100 computer indicated that significant gains in computation time are possible for operations on gloval arrays. However, for element level computations that do not lend themselves easily to long vector processing, the STAR 100 was slower than comparable scalar computers. On this basis it is concluded that in order for pipeline computers to impact the economic feasibility of large nonlinear analyses it is absolutely essential that algorithms be devised to improve the efficiency of element level computations.

Talent management for the twenty-first century.

PubMed

Cappelli, Peter

2008-03-01

Most firms have no formal programs for anticipating and fulfilling talent needs, relying on an increasingly expensive pool of outside candidates that has been shrinking since it was created from the white-collar layoffs of the 1980s. But the advice these companies are getting to solve the problem--institute large-scale internal development programs--is equally ineffective. Internal development was the norm back in the 1950s, and every management-development practice that seems novel today was routine in those years--from executive coaching to 360-degree feedback to job rotation to high-potential programs. However, the stable business environment and captive talent pipelines in which such practices were born no longer exist. It's time for a fundamentally new approach to talent management. Fortunately, companies already have such a model, one that has been well honed over decades to anticipate and meet demand in uncertain environments: supply chain management. Cappelli, a professor at the Wharton School, focuses on four practices in particular. First, companies should balance make-versus-buy decisions by using internal development programs to produce most--but not all--of the needed talent, filling in with outside hiring. Second, firms can reduce the risks in forecasting the demand for talent by sending smaller batches of candidates through more modularized training systems in much the same way manufacturers now employ components in just-in-time production lines. Third, companies can improve their returns on investment in development efforts by adopting novel cost-sharing programs. Fourth, they should seek to protect their investments by generating internal opportunities to encourage newly trained managers to stick with the firm. Taken together, these principles form the foundation for a new paradigm in talent management: a talent-on-demand system.

During the past decade many changes have taken place in the natural gas industry, not the least of which is the way information (data) is acquired, moved, compiled, integrated and disseminated within organizations. At El Paso Natural Gas Company (EPNG) the Operations Control Department has been at the center of these changes. The Systems Section within Operations Control has been instrumental in developing the computer programs that acquire and store real-time operational data, and then make it available to not only the Gas Control function, but also to anyone else within the company who might require it and, to amore » limited degree, any supplier or purchaser of gas utilizing the El Paso pipeline.

Middleware Case Study: MeDICi

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

Wynne, Adam S.

2011-05-05

In many application domains in science and engineering, data produced by sensors, instruments and networks is naturally processed by software applications structured as a pipeline . Pipelines comprise a sequence of software components that progressively process discrete units of data to produce a desired outcome. For example, in a Web crawler that is extracting semantics from text on Web sites, the first stage in the pipeline might be to remove all HTML tags to leave only the raw text of the document. The second step may parse the raw text to break it down into its constituent grammatical parts, suchmore » as nouns, verbs and so on. Subsequent steps may look for names of people or places, interesting events or times so documents can be sequenced on a time line. Each of these steps can be written as a specialized program that works in isolation with other steps in the pipeline. In many applications, simple linear software pipelines are sufficient. However, more complex applications require topologies that contain forks and joins, creating pipelines comprising branches where parallel execution is desirable. It is also increasingly common for pipelines to process very large files or high volume data streams which impose end-to-end performance constraints. Additionally, processes in a pipeline may have specific execution requirements and hence need to be distributed as services across a heterogeneous computing and data management infrastructure. From a software engineering perspective, these more complex pipelines become problematic to implement. While simple linear pipelines can be built using minimal infrastructure such as scripting languages, complex topologies and large, high volume data processing requires suitable abstractions, run-time infrastructures and development tools to construct pipelines with the desired qualities-of-service and flexibility to evolve to handle new requirements. The above summarizes the reasons we created the MeDICi Integration Framework (MIF) that is designed for creating high-performance, scalable and modifiable software pipelines. MIF exploits a low friction, robust, open source middleware platform and extends it with component and service-based programmatic interfaces that make implementing complex pipelines simple. The MIF run-time automatically handles queues between pipeline elements in order to handle request bursts, and automatically executes multiple instances of pipeline elements to increase pipeline throughput. Distributed pipeline elements are supported using a range of configurable communications protocols, and the MIF interfaces provide efficient mechanisms for moving data directly between two distributed pipeline elements.« less

Welding and NDT development in support of Oman-India gas pipeline

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

Even, T.M.; Laing, B.; Hirsch, D.

1995-12-01

The Oman to India gas pipeline is designed for a maximum water depth of 3,500 m. For such a pipeline, resistance to hydrostatic collapse is a critical factor and dictates that very heavy wall pipe be used, preliminarily 24 inch ID x 1.625 inch wall. Because of the water depth, much of the installation will be by J-Lay which requires that the Joint be welded and inspected in a single station. This paper describes the results of welding and NDT test programs conducted to determine the minimum time to perform these operations in heavy wall pipe.

Pipeline corridors through wetlands -- Impacts on plant communities: Norris Brook Crossing Peabody, Massachusetts

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

Shem, L.M.; Van Dyke, G.D.; Zimmerman, R.E.

1994-12-01

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents the results of a survey conducted August 17--19, 1992, at the Norris Brook crossing in the town of Peabody, Essex County, Massachusetts. The pipeline at this site was installed during September and October 1990. A backhoe was used to install the pipeline. The pipe was assembledmore » on the adjacent upland and slid into the trench, after which the backhoe was used again to fill the trench and cover the pipeline. Within two years after pipeline construction, a dense vegetative community, composed predominantly of native perennial species, had become established on the ROW. Compared with adjacent natural areas undisturbed by pipeline installation, there was an increase in purple loosestrife and cattail within the ROW, while large woody species were excluded from the ROW. As a result of the ROW`s presence, habitat diversity, edge-type habitat, and species diversity increased within the site. Crooked-stem aster, Aster prenanthoides (a species on the Massasschusetts list of plants of special concern), occurred in low numbers in the adjacent natural areas and had reinvaded the ROW in low numbers.« less

Extraction of UMLS® Concepts Using Apache cTAKES™ for German Language.

PubMed

Becker, Matthias; Böckmann, Britta

2016-01-01

Automatic information extraction of medical concepts and classification with semantic standards from medical reports is useful for standardization and for clinical research. This paper presents an approach for an UMLS concept extraction with a customized natural language processing pipeline for German clinical notes using Apache cTAKES. The objectives are, to test the natural language processing tool for German language if it is suitable to identify UMLS concepts and map these with SNOMED-CT. The German UMLS database and German OpenNLP models extended the natural language processing pipeline, so the pipeline can normalize to domain ontologies such as SNOMED-CT using the German concepts. For testing, the ShARe/CLEF eHealth 2013 training dataset translated into German was used. The implemented algorithms are tested with a set of 199 German reports, obtaining a result of average 0.36 F1 measure without German stemming, pre- and post-processing of the reports.

Women in Leadership: Why So Few and What to Do About It.

PubMed

Surawicz, Christina M

2016-12-01

The numbers of women in medical school and in medical training have increased dramatically and are near 50% overall, but the number of women who advance to senior and leadership positions is not nearly this high. There are many reasons why the number of women in leadership roles in academic medicine has not kept pace with the number of women entering the field of medicine. Two popular themes are the glass ceiling (referring to an invisible barrier to advancement) and the leaky pipeline (the loss of women faculty along the path, or pipeline, to advancement). I believe that both come into play. Glass ceiling issues tend to be of two types: those related to the institutional culture and those related to problems of bias, especially unconscious bias. Leaky pipeline issues include the challenges of work-life integration and the need for leadership development for women. There are solutions to all of these challenges. These include improving institutional culture; making sure women advance as quickly as men and are paid equitably; ensuring that there are resources to help with work-life balance, related not only to family but to all aspects of life; and providing adequate mentoring and leadership training. These measures will help all faculty, as factors that hamper women's advancement may hamper men as well. Although these themes are broadly applicable, there are strategies that can address them all. We just need to be aware, and be proactive, and we will succeed in breaking the glass ceiling and patching the leaky pipeline. Copyright © 2016 American College of Radiology.

Passive acoustic sensing has emerged as a powerful tool for quantifying anthropogenic impacts on biodiversity, especially for echolocating bat species. To better assess bat population trends there is a critical need for accurate, reliable, and open source tools that allow the detection and classification of bat calls in large collections of audio recordings. The majority of existing tools are commercial or have focused on the species classification task, neglecting the important problem of first localizing echolocation calls in audio which is particularly problematic in noisy recordings. We developed a convolutional neural network based open-source pipeline for detecting ultrasonic, full-spectrum, search-phase calls produced by echolocating bats. Our deep learning algorithms were trained on full-spectrum ultrasonic audio collected along road-transects across Europe and labelled by citizen scientists from www.batdetective.org. When compared to other existing algorithms and commercial systems, we show significantly higher detection performance of search-phase echolocation calls with our test sets. As an example application, we ran our detection pipeline on bat monitoring data collected over five years from Jersey (UK), and compared results to a widely-used commercial system. Our detection pipeline can be used for the automatic detection and monitoring of bat populations, and further facilitates their use as indicator species on a large scale. Our proposed pipeline makes only a small number of bat specific design decisions, and with appropriate training data it could be applied to detecting other species in audio. A crucial novelty of our work is showing that with careful, non-trivial, design and implementation considerations, state-of-the-art deep learning methods can be used for accurate and efficient monitoring in audio.

A deep learning pipeline for Indian dance style classification

NASA Astrophysics Data System (ADS)

Dewan, Swati; Agarwal, Shubham; Singh, Navjyoti

2018-04-01

In this paper, we address the problem of dance style classification to classify Indian dance or any dance in general. We propose a 3-step deep learning pipeline. First, we extract 14 essential joint locations of the dancer from each video frame, this helps us to derive any body region location within the frame, we use this in the second step which forms the main part of our pipeline. Here, we divide the dancer into regions of important motion in each video frame. We then extract patches centered at these regions. Main discriminative motion is captured in these patches. We stack the features from all such patches of a frame into a single vector and form our hierarchical dance pose descriptor. Finally, in the third step, we build a high level representation of the dance video using the hierarchical descriptors and train it using a Recurrent Neural Network (RNN) for classification. Our novelty also lies in the way we use multiple representations for a single video. This helps us to: (1) Overcome the RNN limitation of learning small sequences over big sequences such as dance; (2) Extract more data from the available dataset for effective deep learning by training multiple representations. Our contributions in this paper are three-folds: (1) We provide a deep learning pipeline for classification of any form of dance; (2) We prove that a segmented representation of a dance video works well with sequence learning techniques for recognition purposes; (3) We extend and refine the ICD dataset and provide a new dataset for evaluation of dance. Our model performs comparable or better in some cases than the state-of-the-art on action recognition benchmarks.

Decoding of finger trajectory from ECoG using deep learning.

Conventional decoding pipeline for brain-machine interfaces (BMIs) consists of chained different stages of feature extraction, time-frequency analysis and statistical learning models. Each of these stages uses a different algorithm trained in a sequential manner, which makes it difficult to make the whole system adaptive. The goal was to create an adaptive online system with a single objective function and a single learning algorithm so that the whole system can be trained in parallel to increase the decoding performance. Here, we used deep neural networks consisting of convolutional neural networks (CNN) and a special kind of recurrent neural network (RNN) called long short term memory (LSTM) to address these needs. We used electrocorticography (ECoG) data collected by Kubanek et al. The task consisted of individual finger flexions upon a visual cue. Our model combined a hierarchical feature extractor CNN and a RNN that was able to process sequential data and recognize temporal dynamics in the neural data. CNN was used as the feature extractor and LSTM was used as the regression algorithm to capture the temporal dynamics of the signal. We predicted the finger trajectory using ECoG signals and compared results for the least angle regression (LARS), CNN-LSTM, random forest, LSTM model (LSTM_HC, for using hard-coded features) and a decoding pipeline consisting of band-pass filtering, energy extraction, feature selection and linear regression. The results showed that the deep learning models performed better than the commonly used linear model. The deep learning models not only gave smoother and more realistic trajectories but also learned the transition between movement and rest state. This study demonstrated a decoding network for BMI that involved a convolutional and recurrent neural network model. It integrated the feature extraction pipeline into the convolution and pooling layer and used LSTM layer to capture the state transitions. The discussed network eliminated the need to separately train the model at each step in the decoding pipeline. The whole system can be jointly optimized using stochastic gradient descent and is capable of online learning.

A Low Power and High Throughput Self Synchronous FPGA Using 65nm CMOS with Throughput Optimization by Pipeline Alignment

NASA Astrophysics Data System (ADS)

Stefan Devlin, Benjamin; Nakura, Toru; Ikeda, Makoto; Asada, Kunihiro

We detail a self synchronous field programmable gate array (SSFPGA) with dual-pipeline (DP) architecture to conceal pre-charge time for dynamic logic, and its throughput optimization by using pipeline alignment implemented on benchmark circuits. A self synchronous LUT (SSLUT) consists of a three input tree-type structure with 8bits of SRAM for programming. A self synchronous switch box (SSSB) consists of both pass transistors and buffers to route signals, with 12bits of SRAM. One common block with one SSLUT and one SSSB occupies 2.2Mλ2 area with 35bits of SRAM, and the prototype SSFPGA with 34 × 30 (1020) blocks is designed and fabricated using 65nm CMOS. Measured results show at 1.2V 430MHz and 647MHz operation for a 3bit ripple carry adder, without and with throughput optimization, respectively. We find that using the proposed pipeline alignment techniques we can perform at maximum throughput of 647MHz in various benchmarks on the SSFPGA. We demonstrate up to 56.1 times throughput improvement with our pipeline alignment techniques. The pipeline alignment is carried out within the number of logic elements in the array and pipeline buffers in the switching matrix.

A Collaborative Data Scientist Framework for both Primary and Secondary Education

The earth science data educational pipeline may be dependent on K-20 outcomes. Thus, a challenge for earth science and space informatics education or generational knowledge transfer consideration may be a non-existing or cost prohibitive pedagogical earth science reality. Such may require a technological infrastructure, a validated assessment system, and collaboration among stakeholders of primary and secondary education. Moreover, the K-20 paradigms may engage separate science and technology preparation standards when fundamental informatics requires an integrated pedagogical approach. In simple terms, a collaborative earth science training program for a subset of disciplines may a pragmatics means for formal data scientist training that is sustainable as technology evolves and data-sharing policy becomes a norm of data literacy. As the Group Earth Observation Systems of Systems (GEOSS) has a 10-work plan, educational stakeholders may find funding avenues if government can see earth science data training as a valuable job skill and societal need. This proposed framework suggested that ontological literacy, database management and storage management and data sharing capability are fundamental informatics concepts of this proposed framework where societal engagement is incited. Here all STEM disciplines could incite an integrated approach to mature such as learning metrics in their matriculation and assessment systems. The NSF's Earth Cube and Europe's WISE may represent best cased for such framework implementation.

Workflows for microarray data processing in the Kepler environment.

PubMed

Stropp, Thomas; McPhillips, Timothy; Ludäscher, Bertram; Bieda, Mark

2012-05-17

Microarray data analysis has been the subject of extensive and ongoing pipeline development due to its complexity, the availability of several options at each analysis step, and the development of new analysis demands, including integration with new data sources. Bioinformatics pipelines are usually custom built for different applications, making them typically difficult to modify, extend and repurpose. Scientific workflow systems are intended to address these issues by providing general-purpose frameworks in which to develop and execute such pipelines. The Kepler workflow environment is a well-established system under continual development that is employed in several areas of scientific research. Kepler provides a flexible graphical interface, featuring clear display of parameter values, for design and modification of workflows. It has capabilities for developing novel computational components in the R, Python, and Java programming languages, all of which are widely used for bioinformatics algorithm development, along with capabilities for invoking external applications and using web services. We developed a series of fully functional bioinformatics pipelines addressing common tasks in microarray processing in the Kepler workflow environment. These pipelines consist of a set of tools for GFF file processing of NimbleGen chromatin immunoprecipitation on microarray (ChIP-chip) datasets and more comprehensive workflows for Affymetrix gene expression microarray bioinformatics and basic primer design for PCR experiments, which are often used to validate microarray results. Although functional in themselves, these workflows can be easily customized, extended, or repurposed to match the needs of specific projects and are designed to be a toolkit and starting point for specific applications. These workflows illustrate a workflow programming paradigm focusing on local resources (programs and data) and therefore are close to traditional shell scripting or R/BioConductor scripting approaches to pipeline design. Finally, we suggest that microarray data processing task workflows may provide a basis for future example-based comparison of different workflow systems. We provide a set of tools and complete workflows for microarray data analysis in the Kepler environment, which has the advantages of offering graphical, clear display of conceptual steps and parameters and the ability to easily integrate other resources such as remote data and web services.

2016-06-01

A data processing pipeline for serial femtosecond crystallography at SACLA was developed, based on Cheetah [Barty et al. (2014). J. Appl. Cryst. 47 , 1118-1131] and CrystFEL [White et al. (2016). J. Appl. Cryst. 49 , 680-689]. The original programs were adapted for data acquisition through the SACLA API, thread and inter-node parallelization, and efficient image handling. The pipeline consists of two stages: The first, online stage can analyse all images in real time, with a latency of less than a few seconds, to provide feedback on hit rate and detector saturation. The second, offline stage converts hit images into HDF5 files and runs CrystFEL for indexing and integration. The size of the filtered compressed output is comparable to that of a synchrotron data set. The pipeline enables real-time feedback and rapid structure solution during beamtime.

An image processing pipeline to detect and segment nuclei in muscle fiber microscopic images.

2014-08-01

Muscle fiber images play an important role in the medical diagnosis and treatment of many muscular diseases. The number of nuclei in skeletal muscle fiber images is a key bio-marker of the diagnosis of muscular dystrophy. In nuclei segmentation one primary challenge is to correctly separate the clustered nuclei. In this article, we developed an image processing pipeline to automatically detect, segment, and analyze nuclei in microscopic image of muscle fibers. The pipeline consists of image pre-processing, identification of isolated nuclei, identification and segmentation of clustered nuclei, and quantitative analysis. Nuclei are initially extracted from background by using local Otsu's threshold. Based on analysis of morphological features of the isolated nuclei, including their areas, compactness, and major axis lengths, a Bayesian network is trained and applied to identify isolated nuclei from clustered nuclei and artifacts in all the images. Then a two-step refined watershed algorithm is applied to segment clustered nuclei. After segmentation, the nuclei can be quantified for statistical analysis. Comparing the segmented results with those of manual analysis and an existing technique, we find that our proposed image processing pipeline achieves good performance with high accuracy and precision. The presented image processing pipeline can therefore help biologists increase their throughput and objectivity in analyzing large numbers of nuclei in muscle fiber images. © 2014 Wiley Periodicals, Inc.

Supercomputing on massively parallel bit-serial architectures

Iobst, Ken

1985-01-01

Research on the Goodyear Massively Parallel Processor (MPP) suggests that high-level parallel languages are practical and can be designed with powerful new semantics that allow algorithms to be efficiently mapped to the real machines. For the MPP these semantics include parallel/associative array selection for both dense and sparse matrices, variable precision arithmetic to trade accuracy for speed, micro-pipelined train broadcast, and conditional branching at the processing element (PE) control unit level. The preliminary design of a FORTRAN-like parallel language for the MPP has been completed and is being used to write programs to perform sparse matrix array selection, min/max search, matrix multiplication, Gaussian elimination on single bit arrays and other generic algorithms. A description is given of the MPP design. Features of the system and its operation are illustrated in the form of charts and diagrams.

This paper presents novel research on the development of a generic intelligent oil fraction sensor based on Electrical Capacitance Tomography (ECT) data. An artificial Neural Network (ANN) has been employed as the intelligent system to sense and estimate oil fractions from the cross-sections of two-component flows comprising oil and gas in a pipeline. Previous works only focused on estimating the oil fraction in the pipeline based on fixed ECT sensor parameters. With fixed ECT design sensors, an oil fraction neural sensor can be trained to deal with ECT data based on the particular sensor parameters, hence the neural sensor is not generic. This work focuses on development of a generic neural oil fraction sensor based on training a Multi-Layer Perceptron (MLP) ANN with various ECT sensor parameters. On average, the proposed oil fraction neural sensor has shown to be able to give a mean absolute error of 3.05% for various ECT sensor sizes.

Python is a very popular programming language among data scientists around the world. Python can also be used in hyperspectral data analysis. There are some toolboxes designed for spectral imaging, such as Spectral Python and HyperSpy, but there is a need for analysis pipeline, which is easy to use and agile for different solutions. We propose a Python pipeline which is built on packages xarray, Holoviews and scikit-learn. We have developed some of own tools, MaskAccessor, VisualisorAccessor and a spectral index library. They also fulfill our goal of easy and agile data processing. In this paper we will present our processing pipeline and demonstrate it in practice.

Current and emerging plant diseases caused by obligate parasitic microbes such as rusts, downy mildews, and powdery mildews threaten worldwide crop production and food safety. These obligate parasites are typically unculturable in the laboratory, posing technical challenges to characterize them at the genetic and genomic level. Here we have developed a data analysis pipeline integrating several bioinformatic software programs. This pipeline facilitates rapid gene discovery and expression analysis of a plant host and its obligate parasite simultaneously by next generation sequencing of mixed host and pathogen RNA (i.e., metatranscriptomics). We applied this pipeline to metatranscriptomic sequencing data of sweet basil (Ocimum basilicum) and its obligate downy mildew parasite Peronospora belbahrii, both lacking a sequenced genome. Even with a single data point, we were able to identify both candidate host defense genes and pathogen virulence genes that are highly expressed during infection. This demonstrates the power of this pipeline for identifying genes important in host-pathogen interactions without prior genomic information for either the plant host or the obligate biotrophic pathogen. The simplicity of this pipeline makes it accessible to researchers with limited computational skills and applicable to metatranscriptomic data analysis in a wide range of plant-obligate-parasite systems.

Biomedical preparatory programs (pipeline programs) have been developed at colleges and universities to better prepare youth for entering science- and health-related careers, but outcomes of such programs have seldom been rigorously evaluated. We conducted a matched cohort study to evaluate the Stanford Medical Youth Science Program's Summer Residential Program (SRP), a 25-year-old university-based biomedical pipeline program that reaches out to low-income and underrepresented ethnic minority high school students. Five annual surveys were used to assess educational outcomes and science-related experience among 96 SRP participants and a comparison group of 192 youth who applied but were not selected to participate in the SRP, using ~2:1 matching on sociodemographic and academic background to control for potential confounders. SRP participants were more likely than the comparison group to enter college (100.0 vs. 84.4 %, p = 0.002), and both of these matriculation rates were more than double the statewide average (40.8 %). In most areas of science-related experience, SRP participants reported significantly more experience (>twofold odds) than the comparison group at 1 year of follow-up, but these differences did not persist after 2-4 years. The comparison group reported substantially more participation in science or college preparatory programs, more academic role models, and less personal adversity than SRP participants, which likely influenced these findings toward the null hypothesis. SRP applicants, irrespective of whether selected for participation, had significantly better educational outcomes than population averages. Short-term science-related experience was better among SRP participants, although longer-term outcomes were similar, most likely due to college and science-related opportunities among the comparison group. We discuss implications for future evaluations of other biomedical pipeline programs.

While pipeline programs for students from underrepresented minority groups have been established at the high school and college levels, fewer programs have been developed for middle school students. In an effort to reach this cohort, the University of Detroit Mercy School of Dentistry embarked on a grassroots collaborative pipeline program with two distinct segments: Urban Impressions and Dental Imprint. Their purpose is to expose Detroit-area seventh and eighth grade students to careers in dentistry, provide oral health education, and introduce role models. The aim of this pilot study was to determine outcomes for the middle school participants in Urban Impressions (n=86) and Dental Imprint (n=68). Both segments featured hands-on dental activities at the dental school. Outcomes were assessed by pretest-posttest surveys. Across the three cohorts, a total of 86 students participated in one or more sessions, with 57 completing the pre- and post-program surveys, for a 66% response rate. The results showed that the Dental Imprint respondents' knowledge of oral health, dental admissions, and specialties increased by an average 26% over three years. The gain in knowledge for each cohort was statistically significant (p<0.001). Overall, 91% of Urban Impressions and 95% of Dental Imprint respondents were positive about the value of the program. Thirty-one of 57 Urban Impressions respondents indicated interest in dentistry as a career following the program. These results suggest that the two segments of this program are meeting their goals of increasing middle grade students' awareness of oral health professions including dentistry and providing access to role models. Institutions may benefit from the description of strategies used by this program to address challenges related to establishing early pipeline programs.

Spectroscopic surveys require fast and efficient analysis methods to maximize their scientific impact. Here, we apply a deep neural network architecture to analyse both SDSS-III APOGEE DR13 and synthetic stellar spectra. When our convolutional neural network model (StarNet) is trained on APOGEE spectra, we show that the stellar parameters (temperature, gravity, and metallicity) are determined with similar precision and accuracy as the APOGEE pipeline. StarNet can also predict stellar parameters when trained on synthetic data, with excellent precision and accuracy for both APOGEE data and synthetic data, over a wide range of signal-to-noise ratios. In addition, the statistical uncertainties in the stellar parameter determinations are comparable to the differences between the APOGEE pipeline results and those determined independently from optical spectra. We compare StarNet to other data-driven methods; for example, StarNet and the Cannon 2 show similar behaviour when trained with the same data sets; however, StarNet performs poorly on small training sets like those used by the original Cannon. The influence of the spectral features on the stellar parameters is examined via partial derivatives of the StarNet model results with respect to the input spectra. While StarNet was developed using the APOGEE observed spectra and corresponding ASSET synthetic data, we suggest that this technique is applicable to other wavelength ranges and other spectral surveys.

Given limited funding for school-based science education, non-school-based programs have been developed at colleges and universities to increase the number of students entering science- and health-related careers and address critical workforce needs. However, few evaluations of such programs have been conducted. We report the design and methods of a controlled trial to evaluate the Stanford Medical Youth Science Program's Summer Residential Program (SRP), a 25-year-old university-based biomedical pipeline program. This 5-year matched cohort study uses an annual survey to assess educational and career outcomes among four cohorts of students who participate in the SRP and a matched comparison group of applicants who were not chosen to participate in the SRP. Matching on sociodemographic and academic background allows control for potential confounding. This design enables the testing of whether the SRP has an independent effect on educational- and career-related outcomes above and beyond the effects of other factors such as gender, ethnicity, socioeconomic background, and pre-intervention academic preparation. The results will help determine which curriculum components contribute most to successful outcomes and which students benefit most. After 4 years of follow-up, the results demonstrate high response rates from SRP participants and the comparison group with completion rates near 90 %, similar response rates by gender and ethnicity, and little attrition with each additional year of follow-up. This design and methods can potentially be replicated to evaluate and improve other biomedical pipeline programs, which are increasingly important for equipping more students for science- and health-related careers.

The fate of biomedical research lies in the hands of future generations of scientists. In recent decades the diversity of scientific career opportunities has exploded multidimensionally. However, the educational system for maintaining a pipeline of talented biomedical trainees remains unidimensional and has become outdated. This Viewpoint identifies inadequacies in training and offers potential solutions and implementation strategies to stimulate interest in science at a younger age and to better align individualized training pathways with career opportunities (“precision training”). Both interventions support of the ultimate goal of attracting the best possible future leaders in biomedical science. PMID:28360347

The National Ocean Sciences Bowl: An Effective Model for Engaging High School Students in Ocean Science

NASA Astrophysics Data System (ADS)

Holloway, A. E.

2016-02-01

The National Ocean Sciences Bowl (NOSB) is an informal high school education program that engages students in ocean and environmental science and exposes them to the breadth of ocean-related careers. The NOSB strives to train the next generation of interdisciplinary capable scientists and build a STEM-literate society that harnesses the power of ocean and climate science to address environmental, economic, and societal issues. Through the NOSB, students not only learn scientific principles, but also apply them to compelling real-world problems. The NOSB provides a richer STEM education and exposes students to ocean science topics they may not otherwise study through classroom curriculum. A longitudinal study that began in 2007 has shown that NOSB participants have an enhanced interest in ocean-related hobbies and environmental stewardship and an increasing number of these students have remained in the STEM pipeline and workforce.While the NOSB is primarily an academic competition, it has evolved since its creation in 1998 to include a variety of practical and professional development components. One of the program enhancements, the Scientific Expert Briefing (SEB), gives students the opportunity to apply what they have studied and think critically about current and ongoing ocean science challenges. The SEB helps students connect their knowledge of ocean science with current and proposed policy initiatives. Students gain significant research, writing, and presentation skills, while enhancing their ability for collaboration and consensus building, all vital workforce skills. Ultimately, the SEB teaches students how to communicate complex scientific research into digestible information for decision-makers and the general public.This poster will examine the impact of the NOSB and its role in strengthening the workforce pipeline through a combination of independent learning, competition, and opportunities for communication skills development.

The NASA Nebraska Space Grant Consortium (NSGC) continues to recognize the necessity of increasing the quantity and quality of highly skilled graduates and faculty involved with NASA. Through NASA Workforce Development funds awarded in 2002, NSGC spearheaded customer- focused workforce training and higher education, industry and community partnerships that are significantly impacting the state s workforce in the science, technology, engineering, and mathematics (STEM) competencies. NSGC proposes to build upon these accomplishments to meet the steadily increasing demand for STEM skills and to safeguard minority representation in these disciplines. A wide range of workforce development activities target NASA s need to establish stronger connections among higher education, industry, and community organizations. Participation in the National Student Satellite Program (NSSP), Community Internship Program, and Nebraska Science and Technology Recruitment Fair will extend the pipeline of employees benefiting NASA as well as Nebraska. The diversity component of this proposal catapults from the exceptional reputation NSGC has built by delivering geospatial science experiences to Nebraska s Native Americans. For 6 years, NSGC has fostered and sustained partnerships with the 2 tribal colleges and 4 reservation school districts in Nebraska to foster aeronautics education and outreach. This program, the Nebraska Native American Outreach Program (NNAOP), has grown to incorporate more than educational institutions and is now a partnership among tribal community leaders, academia, tribal schools, and industry. The content focus has broadened from aeronautics in the school systems to aerospace technology and earth science applications in tribal community decision-making and workforce training on the reservations. To date, participants include faculty and staff at 4 Nebraska tribal schools, 2 tribal colleges, approximately 1,000 Native American youth, and over 1,200 community members. This Native American Initiative of the NSGC addresses Nebraska workforce development and serves as a model to others. Following a structured evaluation process, NSGC proposes to sustain delivery of the training funded by NASA in 2002 to tribal entities through partnerships linking academic programs and industry leaders.

2014-01-01

We present a decade's worth of strategies designed to promote and provide "Stepping Stones to Research" to provide a realistic pipeline of educational opportunities, with multiple gateways and exit points, for students moving towards STEM careers along the "STEM pipeline". We also illustrate how the Stepping Stones are designed to incidentally co-inside with related external opportunities through which we can also guide and support our mentees on their paths. We present programs such as middle school family science programs, high school research opportunities, high school internships, undergraduate research pathways, research experiences for undergraduates, and other opportunities. We will highlight the presentations being made at this very meeting -- from the first presentation of a high school student, to a dissertation presentation of a PhD graduate -- that have benefited from this stepping stone principle. We also reflect on the essential nature of building a "researcher-trust", even as a young student, of advocates and mentors who can support the continuation of a scientific career.

Genome annotation is one of the key actions that must be undertaken in order to decipher the genetic blueprint of organisms. Thus, a correct and reliable annotation is essential in rendering genomic data valuable. Here, we describe a bioinformatics pipeline based on freely available software programs coordinated by a multithreaded script named MEGAnnotator (Multithreaded Enhanced prokaryotic Genome Annotator). This pipeline allows the generation of multiple annotated formats fulfilling the NCBI guidelines for assembled microbial genome submission, based on DNA shotgun sequencing reads, and minimizes manual intervention, while also reducing waiting times between software program executions and improving final quality of both assembly and annotation outputs. MEGAnnotator provides an efficient way to pre-arrange the assembly and annotation work required to process NGS genome sequence data. The script improves the final quality of microbial genome annotation by reducing ambiguous annotations. Moreover, the MEGAnnotator platform allows the user to perform a partial annotation of pre-assembled genomes and includes an option to accomplish metagenomic data set assemblies. MEGAnnotator platform will be useful for microbiologists interested in genome analyses of bacteria as well as those investigating the complexity of microbial communities that do not possess the necessary skills to prepare their own bioinformatics pipeline. © FEMS 2016.

Pipeline corridors through wetlands - impacts on plant communities: Deep Creek and Brandy Branch crossings, Nassau County, Florida

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

Shem, L.M.; Van Dyke, G.D.; Zimmerman, R.E.

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents the results of surveys conducted July 14-18, 1992, at the Deep Creek and the Brandy Branch crossings of a pipeline installed during May 1991 in Nassau County, Florida. Both floodplains supported bottomland hardwood forests. The pipeline at the Deep Creek crossing was installed by means ofmore » horizontal directional drilling after the ROW had been clear-cut, while the pipeline at the Brandy Branch crossing was installed by means of conventional open trenching. Neither site was seeded or fertilized. At the time of sampling, a dense vegetative community, made up primarily of native perennial herbaceous species, occupied the ROW within the Deep Creek floodplain. The Brandy Branch ROW was vegetated by a less dense stand of primarily native perennial herbaceous plants. Plant diversity was also lower at the Brandy Branch crossing than at the Deep Creek crossing. The results suggest that some of the differences in plant communities are related to the more hydric conditions at the Brandy Branch floodplain.« less

Telluric currents: A meeting of theory and observation

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

Boteler, D.H.; Seager, W.H.

Pipe-to-soil (P/S) potential variations resulting from telluric currents have been observed on pipelines in many locations. However, it has never teen clear which parts of a pipeline will experience the worst effects. Two studies were conducted to answer this question. Distributed-source transmission line (DSTL) theory was applied to the problem of modeling geomagnetic induction in pipelines. This theory predicted that the largest P/S potential variations would occur at the ends of the pipeline. The theory also predicted that large P/S potential variations, of opposite sign, should occur on either side of an insulating flange. Independently, an observation program was conductedmore » to determine the change in telluric current P/S potential variations and to design counteractive measures along a pipeline in northern Canada. Observations showed that the amplitude of P/S potential fluctuations had maxima at the northern and southern ends of the pipeline. A further set of recordings around an insulating flange showed large P/S potential variations, of opposite sign, on either side of the flange. Agreement between the observations and theoretical predictions was remarkable. While the observations confirmed the theory, the theory explains how P/S potential variations are produced by telluric currents and provides the basis for design of cathodic protection systems for pipelines that can counteract any adverse telluric effects.« less

Modern computational neuroscience employs diverse software tools and multidisciplinary expertise to analyze heterogeneous brain data. The classical problems of gathering meaningful data, fitting specific models, and discovering appropriate analysis and visualization tools give way to a new class of computational challenges—management of large and incongruous data, integration and interoperability of computational resources, and data provenance. We designed, implemented and validated a new paradigm for addressing these challenges in the neuroimaging field. Our solution is based on the LONI Pipeline environment [3], [4], a graphical workflow environment for constructing and executing complex data processing protocols. We developed study-design, database and visual language programming functionalities within the LONI Pipeline that enable the construction of complete, elaborate and robust graphical workflows for analyzing neuroimaging and other data. These workflows facilitate open sharing and communication of data and metadata, concrete processing protocols, result validation, and study replication among different investigators and research groups. The LONI Pipeline features include distributed grid-enabled infrastructure, virtualized execution environment, efficient integration, data provenance, validation and distribution of new computational tools, automated data format conversion, and an intuitive graphical user interface. We demonstrate the new LONI Pipeline features using large scale neuroimaging studies based on data from the International Consortium for Brain Mapping [5] and the Alzheimer's Disease Neuroimaging Initiative [6]. User guides, forums, instructions and downloads of the LONI Pipeline environment are available at http://pipeline.loni.ucla.edu. PMID:20927408

Training and Mentoring the Next Generation of Scientists and Engineers to Secure Continuity and Successes of the US DOE's Environmental Remediation Efforts - 13387

Lagos, L.

The DOE Office of Environmental Management (DOE-EM) oversees one of the largest and most technically challenging cleanup programs in the world. The mission of DOE-EM is to complete the safe cleanup of the environmental legacy from five decades of nuclear weapons development and government-sponsored nuclear energy research. Since 1995, Florida International University's Applied Research Center (FIU-ARC) has supported the DOE-EM mission and provided unique research capabilities to address some of these highly technical and difficult challenges. This partnership has allowed FIU-ARC to create a unique infrastructure that is critical for the training and mentoring of science, technology, engineering, and mathmore » (STEM) students and has exposed many STEM students to 'hands-on' DOE-EM applied research, supervised by the scientists and engineers at ARC. As a result of this successful partnership between DOE and FIU, DOE requested FIU-ARC to create the DOE-FIU Science and Technology Workforce Development Initiative in 2007. This innovative program was established to create a 'pipeline' of minority STEM students trained and mentored to enter DOE's environmental cleanup workforce. The program was designed to help address DOE's future workforce needs by partnering with academic, government and private companies (DOE contractors) to mentor future minority scientists and engineers in the research, development, and deployment of new technologies and processes addressing DOE's environmental cleanup challenges. Since its inception in 2007, the program has trained and mentored 78 FIU STEM minority students. Although, the program has been in existence for only five years, a total of 75 internships have been conducted at DOE National Laboratories, DOE sites, DOE Headquarters and field offices, and DOE contractors. Over 85 DOE Fellows have participated in the Waste Management Symposia since 2008 with a total of 68 student posters and 7 oral presentations given at WM. The DOE Fellows participation at WM has resulted in three Best Student Poster Awards (WM09, WM10, and WM11) and one Best Professional Poster Award (WM09). DOE Fellows have also presented their research at ANS DD and R and ANS Robotics Topical meetings. Moreover, several of our DOE Fellows have already obtained employment with DOE-EM, other federal agencies, DOE contractors. This paper will discuss how DOE Fellows program is training and mentoring FIU STEM students in Department of Energy's Office of Environmental Management technical challenges and research. This training and mentoring has resulted in the development of well trained and polished young scientists and engineers that will become the future workforce in charge of carrying on DOE-EM's environmental cleanup mission. The paper will showcase FIU's DOE Fellows model and highlight some of the applied research the DOE Fellows have conducted at FIU's Applied Research Center and across the Complex by participating in summer internship assignments. This paper will also present and highlight other Fellowships and internships programs sponsored by National Nuclear Security Agency (NNSA), DOE-EM, NRC, Energy (NE), and other federal agencies targeting workforce development.

2014-05-15

The initial steps in the analysis of next-generation sequencing data can be automated by way of software 'pipelines'. However, individual components depreciate rapidly because of the evolving technology and analysis methods, often rendering entire versions of production informatics pipelines obsolete. Constructing pipelines from Linux bash commands enables the use of hot swappable modular components as opposed to the more rigid program call wrapping by higher level languages, as implemented in comparable published pipelining systems. Here we present Next Generation Sequencing ANalysis for Enterprises (NGSANE), a Linux-based, high-performance-computing-enabled framework that minimizes overhead for set up and processing of new projects, yet maintains full flexibility of custom scripting when processing raw sequence data. Ngsane is implemented in bash and publicly available under BSD (3-Clause) licence via GitHub at https://github.com/BauerLab/ngsane. Denis.Bauer@csiro.au Supplementary data are available at Bioinformatics online.

A graph-based approach for designing extensible pipelines

PubMed Central

2012-01-01

Background In bioinformatics, it is important to build extensible and low-maintenance systems that are able to deal with the new tools and data formats that are constantly being developed. The traditional and simplest implementation of pipelines involves hardcoding the execution steps into programs or scripts. This approach can lead to problems when a pipeline is expanding because the incorporation of new tools is often error prone and time consuming. Current approaches to pipeline development such as workflow management systems focus on analysis tasks that are systematically repeated without significant changes in their course of execution, such as genome annotation. However, more dynamism on the pipeline composition is necessary when each execution requires a different combination of steps. Results We propose a graph-based approach to implement extensible and low-maintenance pipelines that is suitable for pipeline applications with multiple functionalities that require different combinations of steps in each execution. Here pipelines are composed automatically by compiling a specialised set of tools on demand, depending on the functionality required, instead of specifying every sequence of tools in advance. We represent the connectivity of pipeline components with a directed graph in which components are the graph edges, their inputs and outputs are the graph nodes, and the paths through the graph are pipelines. To that end, we developed special data structures and a pipeline system algorithm. We demonstrate the applicability of our approach by implementing a format conversion pipeline for the fields of population genetics and genetic epidemiology, but our approach is also helpful in other fields where the use of multiple software is necessary to perform comprehensive analyses, such as gene expression and proteomics analyses. The project code, documentation and the Java executables are available under an open source license at http://code.google.com/p/dynamic-pipeline. The system has been tested on Linux and Windows platforms. Conclusions Our graph-based approach enables the automatic creation of pipelines by compiling a specialised set of tools on demand, depending on the functionality required. It also allows the implementation of extensible and low-maintenance pipelines and contributes towards consolidating openness and collaboration in bioinformatics systems. It is targeted at pipeline developers and is suited for implementing applications with sequential execution steps and combined functionalities. In the format conversion application, the automatic combination of conversion tools increased both the number of possible conversions available to the user and the extensibility of the system to allow for future updates with new file formats.

SSR_pipeline: a bioinformatic infrastructure for identifying microsatellites from paired-end Illumina high-throughput DNA sequencing data

Miller, Mark P.; Knaus, Brian J.; Mullins, Thomas D.; Haig, Susan M.

2013-01-01

SSR_pipeline is a flexible set of programs designed to efficiently identify simple sequence repeats (e.g., microsatellites) from paired-end high-throughput Illumina DNA sequencing data. The program suite contains 3 analysis modules along with a fourth control module that can automate analyses of large volumes of data. The modules are used to 1) identify the subset of paired-end sequences that pass Illumina quality standards, 2) align paired-end reads into a single composite DNA sequence, and 3) identify sequences that possess microsatellites (both simple and compound) conforming to user-specified parameters. The microsatellite search algorithm is extremely efficient, and we have used it to identify repeats with motifs from 2 to 25bp in length. Each of the 3 analysis modules can also be used independently to provide greater flexibility or to work with FASTQ or FASTA files generated from other sequencing platforms (Roche 454, Ion Torrent, etc.). We demonstrate use of the program with data from the brine fly Ephydra packardi (Diptera: Ephydridae) and provide empirical timing benchmarks to illustrate program performance on a common desktop computer environment. We further show that the Illumina platform is capable of identifying large numbers of microsatellites, even when using unenriched sample libraries and a very small percentage of the sequencing capacity from a single DNA sequencing run. All modules from SSR_pipeline are implemented in the Python programming language and can therefore be used from nearly any computer operating system (Linux, Macintosh, and Windows).

Each of the 3 analysis modules can also be used independently to provide greater flexibility or to work with FASTQ or FASTA files generated from other sequencing platforms (Roche 454, Ion Torrent, etc.). We demonstrate use of the program with data from the brine fly Ephydra packardi (Diptera: Ephydridae) and provide empirical timing benchmarks to illustrate program performance on a common desktop computer environment. We further show that the Illumina platform is capable of identifying large numbers of microsatellites, even when using unenriched sample libraries and a very small percentage of the sequencing capacity from a single DNA sequencing run. All modules from SSR_pipeline are implemented in the Python programming language and can therefore be used from nearly any computer operating system (Linux, Macintosh, and Windows).

Based on the analysis of Laplacian image fusion algorithm, this paper proposes a partial pipelining and modular processing architecture, and a SoC based acceleration system is implemented accordingly. Full pipelining method is used for the design of each module, and modules in series form the partial pipelining with unified data formation, which is easy for management and reuse. Integrated with ARM processor, DMA and embedded bare-mental program, this system achieves 4 layers of Laplacian pyramid on the Zynq-7000 board. Experiments show that, with small resources consumption, a couple of 256×256 images can be fused within 1ms, maintaining a fine fusion effect at the same time.

2013-01-01

Given limited funding for school-based science education, non-school-based programs have been developed at colleges and universities to increase the number of students entering science- and health-related careers and address critical workforce needs. However, few evaluations of such programs have been conducted. We report the design and methods of a controlled trial to evaluate the Stanford Medical Youth Science Program’s Summer Residential Program (SRP), a 25-year-old university-based biomedical pipeline program. This 5-year matched cohort study uses an annual survey to assess educational and career outcomes among four cohorts of students who participate in the SRP and a matched comparison group of applicants who were not chosen to participate in the SRP. Matching on sociodemographic and academic background allows control for potential confounding. This design enables the testing of whether the SRP has an independent effect on educational- and career-related outcomes above and beyond the effects of other factors such as gender, ethnicity, socioeconomic background, and pre-intervention academic preparation. The results will help determine which curriculum components contribute most to successful outcomes and which students benefit most. After 4 years of follow-up, the results demonstrate high response rates from SRP participants and the comparison group with completion rates near 90%, similar response rates by gender and ethnicity, and little attrition with each additional year of follow-up. This design and methods can potentially be replicated to evaluate and improve other biomedical pipeline programs, which are increasingly important for equipping more students for science- and health-related careers.

Tappis, Hannah; Doocy, Shannon; Amoako, Stephen

2013-01-01

ABSTRACT Despite decades of support for international food assistance programs by the U.S. Agency for International Development (USAID) Office of Food for Peace, relatively little is known about the commodity pipeline and management issues these programs face in post-conflict and politically volatile settings. Based on an audit of the program's commodity tracking system and interviews with 13 key program staff, this case study documents the experiences of organizations implementing the first USAID-funded non-emergency (development) food assistance program approved for Sudan and South Sudan. Key challenges and lessons learned in this experience about food commodity procurement, transport, and management may help improve the design and implementation of future development food assistance programs in a variety of complex, food-insecure settings around the world. Specifically, expanding shipping routes in complex political situations may facilitate reliable and timely commodity delivery. In addition, greater flexibility to procure commodities locally, rather than shipping U.S.-procured commodities, may avoid unnecessary shipping delays and reduce costs. PMID:25276532

The efficient development of antiviral drugs, including efficient antiviral small interfering RNAs (siRNAs), requires continuous monitoring of the strict correspondence between a drug and the related highly variable viral DNA/RNA target(s). Deep sequencing is able to provide an assessment of both the general target conservation and the frequency of particular mutations in the different target sites. The aim of this study was to develop a reliable bioinformatic pipeline for the analysis of millions of short, deep sequencing reads corresponding to selected highly variable viral sequences that are drug target(s). The suggested bioinformatic pipeline combines the available programs and the ad hoc scripts based on an original algorithm of the search for the conserved targets in the deep sequencing data. We also present the statistical criteria for the threshold of reliable mutation detection and for the assessment of variations between corresponding data sets. These criteria are robust against the possible sequencing errors in the reads. As an example, the bioinformatic pipeline is applied to the study of the conservation of RNA interference (RNAi) targets in human immunodeficiency virus 1 (HIV-1) subtype A. The developed pipeline is freely available to download at the website http://virmut.eimb.ru/. Brief comments and comparisons between VirMut and other pipelines are also presented.

A De Novo-Assembly Based Data Analysis Pipeline for Plant Obligate Parasite Metatranscriptomic Studies

Current and emerging plant diseases caused by obligate parasitic microbes such as rusts, downy mildews, and powdery mildews threaten worldwide crop production and food safety. These obligate parasites are typically unculturable in the laboratory, posing technical challenges to characterize them at the genetic and genomic level. Here we have developed a data analysis pipeline integrating several bioinformatic software programs. This pipeline facilitates rapid gene discovery and expression analysis of a plant host and its obligate parasite simultaneously by next generation sequencing of mixed host and pathogen RNA (i.e., metatranscriptomics). We applied this pipeline to metatranscriptomic sequencing data of sweet basil (Ocimum basilicum) and its obligate downy mildew parasite Peronospora belbahrii, both lacking a sequenced genome. Even with a single data point, we were able to identify both candidate host defense genes and pathogen virulence genes that are highly expressed during infection. This demonstrates the power of this pipeline for identifying genes important in host–pathogen interactions without prior genomic information for either the plant host or the obligate biotrophic pathogen. The simplicity of this pipeline makes it accessible to researchers with limited computational skills and applicable to metatranscriptomic data analysis in a wide range of plant-obligate-parasite systems.

We have been offering a successful BS degree in optical engineering for the past ten years. We have produced more than 100 graduates, highly trained in basic optics and electronics. Our Industrial Affiliates, while very pleased with our graduates, requested that we produce some with greater mechanical engineering skills and knowledge. Our response was the creation of a new degree program, retaining the virtues of the previous one, but allowing a high degree of flexibility through the inclusion of minors within the program. The new program allows sufficient room for a variety of minors. Engineering minors identified include aerospace, computer, electrical, materials and mechanical. Science minors include astronomy, computer science, math and physics. Non-science minors accommodated include business, pre-health and pre-law. The new BSO program features: (1) Better structure and flow, more tightly coupling related classes; (2) New laboratory classes for juniors, linked to lecture classes; (3) Expanded optical deign, fabrication and testing classes; (4) New class in electronics for optics; (5) New classes in fiber optics and optical communications; (6) New capstone/senior project class for ABET compliance. This new BSO program will produce better entry-level optical scientists and engineers, and better candidates for graduate school. Our interactions with the external community will provide inputs concerning industrial needs, leading towards improved student counseling and program development. We will better serve national needs for skilled personnel in optics, and contribute even more to the optics workforce pipeline.

A partnership between Fort Valley State University (FVSU), the Jackson School of Geosciences at The University of Texas (UT) at Austin, and the Texas Advanced Computing Center (TACC) is engaging computational geoscience faculty and researchers with academically talented underrepresented minority (URM) students, training them to solve grand challenges . These next generation computational geoscientists are being trained to solve some of the world's most challenging geoscience grand challenges requiring data intensive large scale modeling and simulation on high performance computers . UT Austin's geoscience outreach program GeoFORCE, recently awarded the Presidential Award in Excellence in Science, Mathematics and Engineering Mentoring, contributes to the collaborative best practices in engaging researchers with URM students. Collaborative efforts over the past decade are providing data demonstrating that integrative pipeline programs with mentoring and paid internship opportunities, multi-year scholarships, computational training, and communication skills development are having an impact on URMs developing middle skills for geoscience careers. Since 1997, the Cooperative Developmental Energy Program at FVSU and its collaborating universities have graduated 87 engineers, 33 geoscientists, and eight health physicists. Recruited as early as high school, students enroll for three years at FVSU majoring in mathematics, chemistry or biology, and then transfer to UT Austin or other partner institutions to complete a second STEM degree, including geosciences. A partnership with the Integrative Computational Education and Research Traineeship (ICERT), a National Science Foundation (NSF) Research Experience for Undergraduates (REU) Site at TACC provides students with a 10-week summer research experience at UT Austin. Mentored by TACC researchers, students with no previous background in computational science learn to use some of the world's most powerful high performance computing resources to address a grand geosciences problem. Students increase their ability to understand and explain the societal impact of their research and communicate the research to multidisciplinary and lay audiences via near-peer mentoring, poster presentations, and publication opportunities.

1994-12-01

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipelines on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and right-of-way (ROW) management practices. This report presents the results of a survey conducted over the period of August 3-4, 1992, at the Cassadaga wetlands crossing in Gerry Township, Chautauqua County, New York. The pipeline at this site was installed during February and March 1981. After completion of pipeline installation, the ROW was fertilized,more » mulched, and seeded with annual ryegrass. Two adjacent sites were surveyed in this study: a forested wetland and an emergent wetlands Eleven years after pipeline installation, the ROW at both sites supported diverse vegetative communities. Although devoid of large woody species, the ROW within the forested wetland had a dense vegetative cover. The ROW within the emergent wetland had a slightly less dense and more diverse vegetative community compared with that in the adjacent natural areas (NAs). The ROW within the emergent wetland also had a large number of introduced species that were not present in the adjacent NAs. The ROW, with its emergent marsh plant community, provided habitat diversity within the forested wetlands Because the ROW contained species not found within the adjacent NAs, overall species diversity was increased.« less

Why students drop out of the pipeline to health professions careers: a follow-up of gifted minority high school students.

PubMed

Thurmond, V B; Cregler, L L

1999-04-01

To track gifted underrepresented minority (URM) students who entered the pipeline to health professional school when they were in high school and to determine whether and why students left the pipeline to enter other professions. A questionnaire was mailed to 162 students who had participated in the Student Educational Enrichment Program (SEEP) in health sciences at the Medical College of Georgia between 1984 and 1991; 123 (75%) responded. Students in the study population had higher graduation rates than the average state or national student. Fifty-nine (48%) of the students had entered health care careers; 98% had stated that intention when they were in high school. Although some of the students stated trouble with course work and GPA as reasons for their decisions to change career tracks, many students said that their interests in non-medical careers had been fostered by mentors or by opportunities to serve internships. Early intervention is important to retaining students in a pipeline that leads to a health care career. Summer programs are successful, but may not be enough to help students with difficult science courses in college, especially chemistry. However, another important conclusion is that much more needs to be done to help students find mentors with whom they can develop relationships and to give them opportunities to work in health care settings.

Measuring the Success of a Pipeline Program to Increase Nursing Workforce Diversity.

2016-01-01

The purpose of this study was to understand changes in knowledge and opinions of underserved American Indian and Hispanic high school students after attending a 2-week summer pipeline program using and testing a pre/postsurvey. The research aims were to (a) psychometrically analyze the survey to determine if scale items could be summed to create a total scale score or subscale scores; (b) assess change in scores pre/postprogram; and (c) examine the survey to make suggestions for modifications and further testing to develop a valid tool to measure changes in student perceptions about going to college and nursing as a result of pipeline programs. Psychometric analysis indicated poor model fit for a 1-factor model for the total scale and majority of subscales. Nonparametric tests indicated statistically significant increases in 13 items and decreases in 2 items. Therefore, while total scores or subscale scores cannot be used to assess changes in perceptions from pre- to postprogram, the survey can be used to examine changes over time in each item. Student did not have an accurate view of nursing and college and underestimated support needed to attend college. However students realized that nursing was a profession with autonomy, respect, and honor. Copyright © 2016 Elsevier Inc. All rights reserved.

In this paper, we propose deformable deep convolutional neural networks for generic object detection. This new deep learning object detection framework has innovations in multiple aspects. In the proposed new deep architecture, a new deformation constrained pooling (def-pooling) layer models the deformation of object parts with geometric constraint and penalty. A new pre-training strategy is proposed to learn feature representations more suitable for the object detection task and with good generalization capability. By changing the net structures, training strategies, adding and removing some key components in the detection pipeline, a set of models with large diversity are obtained, which significantly improves the effectiveness of model averaging. The proposed approach improves the mean averaged precision obtained by RCNN [16], which was the state-of-the-art, from 31% to 50.3% on the ILSVRC2014 detection test set. It also outperforms the winner of ILSVRC2014, GoogLeNet, by 6.1%. Detailed component-wise analysis is also provided through extensive experimental evaluation, which provides a global view for people to understand the deep learning object detection pipeline.

Update on the SDSS-III MARVELS data pipeline development

MARVELS (Multi-object APO Radial Velocity Exoplanet Large-area Survey), as one of the four surveys in the SDSS-III program, has monitored over 3,300 stars during 2008-2012, with each being visited an average of 26 times over a 2-year window. Although the early data pipeline was able to detect over 20 brown dwarf candidates and several hundreds of binaries, no giant planet candidates have been reliably identified due to its large systematic errors. Learning from past data pipeline lessons, we re-designed the entire pipeline to handle various types of systematic effects caused by the instrument (such as trace, slant, distortion, drifts and dispersion) and observation condition changes (such as illumination profile and continuum). We also introduced several advanced methods to precisely extract the RV signals. To date, we have achieved a long term RMS RV measurement error of 14 m/s for HIP-14810 (one of our reference stars) after removal of the known planet signal based on previous HIRES RV measurement. This new 1-D data pipeline has been used to robustly identify four giant planet candidates within the small fraction of the survey data that has been processed (Thomas et al. this meeting). The team is currently working hard to optimize the pipeline, especially the 2-D interference-fringe RV extraction, where early results show a 1.5 times improvement over the 1-D data pipeline. We are quickly approaching the survey baseline performance requirement of 10-35 m/s RMS for 8-12 solar type stars. With this fine-tuned pipeline and the soon to be processed plates of data, we expect to discover many more giant planet candidates and make a large statistical impact to the exoplanet study.

Attracting Girls into Physics (abstract)

NASA Astrophysics Data System (ADS)

Gadalla, Afaf

2009-04-01

A recent international study of women in physics showed that enrollment in physics and science is declining for both males and females and that women are severely underrepresented in careers requiring a strong physics background. The gender gap begins early in the pipeline, from the first grade. Girls are treated differently than boys at home and in society in ways that often hinder their chances for success. They have fewer freedoms, are discouraged from accessing resources or being adventurous, have far less exposure to problem solving, and are not encouraged to choose their lives. In order to motivate more girl students to study physics in the Assiut governorate of Egypt, the Assiut Alliance for the Women and Assiut Education District collaborated in renovating the education of physics in middle and secondary school classrooms. A program that helps in increasing the number of girls in science and physics has been designed in which informal groupings are organized at middle and secondary schools to involve girls in the training and experiences needed to attract and encourage girls to learn physics. During implementation of the program at some schools, girls, because they had not been trained in problem-solving as boys, appeared not to be as facile in abstracting the ideas of physics, and that was the primary reason for girls dropping out of science and physics. This could be overcome by holding a topical physics and technology summer school under the supervision of the Assiut Alliance for the Women.

This paper is the first in a five-part series on the clinical and translational science educational pipeline and presents strategies to support recruitment and retention to create diverse pathways into clinical and translational research (CTR). The strategies address multiple levels or contexts of persistence decisions and include: (1) creating a seamless pipeline by forming strategic partnerships to achieve continuity of support for scholars and collective impact; (2) providing meaningful research opportunities to support identity formation as a scientist and sustain motivation to pursue and persist in CTR careers; (3) fostering an environment for effective mentorship and peer support to promote academic and social integration; (4) advocating for institutional policies to alleviate environmental pull factors; and, (5) supporting program evaluation-particularly, the examination of longitudinal outcomes. By combining institutional policies that promote a culture and climate for diversity with quality, evidence-based programs and integrated networks of support, we can create the environment necessary for diverse scholars to progress successfully and efficiently through the pipeline to achieve National Institutes of Health's vision of a robust CTR workforce. © 2015 Wiley Periodicals, Inc.

The DOE fellows program-a workforce development initiative for the US department of energy

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

Lagos, Leonel E.

The US Department of Energy Office of Environmental Management (DOE-EM) oversees one of the largest and most technically challenging cleanup programs in the world. The mission of DOE-EM is to complete the safe cleanup of the environmental legacy from five decades of nuclear weapons development and government-sponsored nuclear energy research. Since 1995, Florida International University's Applied Research Center (FIU-ARC) has supported the DOE-EM mission and provided unique research capabilities to address some of these highly technical and difficult challenges. This partnership has allowed FIU-ARC to create a unique infrastructure that is critical for the training and mentoring of science, technology,more » engineering, and math (STEM) students and has exposed many STEM students to 'hands-on' DOE-EM applied research, supervised by the scientists and engineers at ARC. As a result of this successful partnership between DOE and FIU, DOE requested FIU-ARC to create the DOE-FIU Science and Technology Workforce Development Initiative in 2007. This innovative program was established to create a 'pipeline' of minority STEM students trained and mentored to enter DOE's environmental cleanup workforce. The program was designed to help address DOE's future workforce needs by partnering with academic, government and private companies (DOE contractors) to mentor future minority scientists and engineers in the research, development, and deployment of new technologies and processes addressing DOE's environmental cleanup challenges. Since its inception in 2007, the program has trained and mentored 78 FIU STEM minority students. Although, the program has been in existence for only six years, a total of 75 internships have been conducted at DOE National Laboratories, DOE sites, DOE Headquarters and field offices, and DOE contractors. Over 100 DOE Fellows have participated in the Waste Management (WM) Symposia since 2008 with a total of 84 student posters and 7 oral presentations given at WM. The DOE Fellows participation at WM has resulted in three Best Student Poster Awards (WM09, WM10, and WM11) and one Best Professional Poster Award (WM09). DOE Fellows have also presented their research at ANS DD and R and ANS Robotics Topical meetings and this year two Fellows will present at the International Conference on Environmental Remediation and Radioactive Waste Management (ICEM13) in Brussels, Belgium. Moreover, several of our DOE Fellows have already obtained employment with DOE-EM, other federal agencies, DOE contractors, commercial nuclear power companies, and other STEM industry (GE, Boeing, Lockheed Martin, Johnson and Johnson, Beckman-Coulter, and other top companies). This paper will discuss how DOE Fellows program is training and mentoring FIU STEM students in Department of Energy's Office of Environmental Management technical challenges and research. This training and mentoring has resulted in the development of well-trained and polished young scientists and engineers that will become the future workforce in charge of carrying on DOE-EM's environmental cleanup mission. The paper will showcase FIU's DOE Fellows model and highlight some of the applied research the DOE Fellows have conducted at FIU's Applied Research Center and across the DOE Complex by participating in summer internship assignments.

World Bank oil-pipeline project designed to prevent HIV transmission.

PubMed

Kigotho, A W

1997-11-29

A World Bank-funded oil pipeline project, in Chad and Cameroon, is the first large-scale construction project in sub-Saharan Africa to incorporate an HIV/AIDS prevention component. The project entails the development of oil fields in southern Chad and construction of 1100 km of pipeline to port facilities on Cameroon's Atlantic coast. 3000 construction workers from the two countries will be employed between 1998 and 2001, including about 600 truck drivers. In some areas along the pipeline route, 50% of the prostitutes (who are frequented by truck drivers) are HIV-infected. The HIV/AIDS intervention aims to prevent HIV and sexually transmitted diseases (STDs) among project workers through social marketing of condoms, treatment of STDs in prostitutes along the route, and health education to modify high-risk behaviors. The program is considered a test case for African governments and donors interested in whether the integration of a health component in major construction projects can avoid AIDS epidemics in affected countries.

Aerial image databases for pipeline rights-of-way management

1996-03-01

Pipeline companies that own and manage extensive rights-of-way corridors are faced with ever-increasing regulatory pressures, operating issues, and the need to remain competitive in today's marketplace. Automation has long been an answer to the problem of having to do more work with less people, and Automated Mapping/Facilities Management/Geographic Information Systems (AM/FM/GIS) solutions have been implemented at several pipeline companies. Until recently, the ability to cost-effectively acquire and incorporate up-to-date aerial imagery into these computerized systems has been out of the reach of most users. NASA's Earth Observations Commercial Applications Program (EOCAP) is providing a means by which pipeline companies can bridge this gap. The EOCAP project described in this paper includes a unique partnership with NASA and James W. Sewall Company to develop an aircraft-mounted digital camera system and a ground-based computer system to geometrically correct and efficiently store and handle the digital aerial images in an AM/FM/GIS environment. This paper provides a synopsis of the project, including details on (1) the need for aerial imagery, (2) NASA's interest and role in the project, (3) the design of a Digital Aerial Rights-of-Way Monitoring System, (4) image georeferencing strategies for pipeline applications, and (5) commercialization of the EOCAP technology through a prototype project at Algonquin Gas Transmission Company which operates major gas pipelines in New England, New York, and New Jersey.

Pipeline corridors through wetlands - impacts on plant communities: Bayou Grand Cane, De Soto Parish, Louisiana. Topical report, August 1991--July 1993

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

Shem, L.M.; Zimmerman, R.E.; Hayes, D.

The goal of the Gas Research Institute Wetland Corridors Program is to document impacts of existing pipeline on the wetlands they traverse. To accomplish this goal, 12 existing wetland crossings were surveyed. These sites varied in elapsed time since pipeline construction, wetland type, pipeline installation techniques, and night of-way (ROW) management practices. This report presents the results of a survey conducted over the period of August 12-13, 1991, at the Bayou Grand Cane crossing in De Soto Parish, Louisiana, where a pipeline constructed three years prior to the survey crosses the bayou through mature bottomland hardwoods. The sit was notmore » seeded or fertilized after construction activities. At the time of sampling, a dense herb stratum (composed of mostly native species) covered the 20-m-wide ROW, except within drainage channels. As a result of the creation of the ROW, new habitat was created, plant diversity increased, and forest habitat became fragmented. The ROW must be maintained at an early stage of succession to allow access to the pipeline however, impacts to the wetland were minimized by decreasing the width of the ROW to 20 m and recreating the drainage channels across the ROW. The canopy trees on the ROW`s edge shaded part of the ROW, which helped to minimize the effects of the ROW.« less

Increasing Diversity in the Geosciences at the City University of New York

NASA Astrophysics Data System (ADS)

Damas, C.; Johnson, L.; McHugh, C.; Marchese, P. J.

2007-12-01

The City University of New York (CUNY) is the nation's largest urban university, with 23 institutions serving a large number of underrepresented minority (URM) and women students at all levels of the pipeline - community college to graduate school. CUNY has a strong record of recruiting, enrolling, retaining and graduating URMs in science, technology, engineering and mathematics (STEM) fields. Current efforts are underway to increase the number of URMs in the geosciences. These efforts include: 1) involving students in research at all levels of the pipeline; 2) incorporating innovative and proven pedagogical methods into the classroom; and 3) mentoring of students by research scientists from CUNY and other participating institutions. At all levels of the pipeline, students are actively engaged in Space and Earth Science research. At the community college level, students are introduced to the scientific research process through familiar software such as MS Excel to analyze simple time series. At the senior colleges, students progress to multi-variate data analysis, and they also have the opportunity to go into the field to collect data. As graduate students, they are involved as mentors and supervise undergraduate student research. Program initiatives such as the CUNY pipeline provide stipends and academic enrichment activities (i.e., GRE training, applying to graduate school, etc.) throughout the summer and academic year. During the summer, students also have the opportunity to work with and be mentored by research scientists at a CUNY campus, at a NASA center or a national laboratory. Mentors advise students about graduate school and careers, serve as role models, and perhaps more importantly, provide encouragement to students who lack confidence in their ability to do scientific research. Students also are expected to present their research findings at meetings and conferences, both locally and nationally. In addition to their research experiences, students also benefit from classroom instructions that emphasize active learning, and the integration of research related activities. Proven educational materials and pedagogical methods developed at Medgar Evers College and Queensborough Community College have proven quite effective at engaging and assisting students who have conceptual difficulties in their science and mathematics courses. Overall, students demonstrate an increase in their conceptual understanding of the subject matter, as well an increase in their confidence to solve scientific problems and to become scientists.

Sheth, Kartik; Mills, Elisabeth A. C.; Hooper, Eric; National Astronomy Consortium

2015-01-01

The National Astronomy Consortium (NAC; see https://sites.google.com/site/nraonac/) is a growing national partnership between majority and minority universities and institutions with the goal of increasing the numbers of under-represented minorities and students who might otherwise be overlooked by the traditional academic pipeline into STEM, or related, careers. The NAC model is based on the successful 'Posse Foundation' model for undergraduate success and incorporates all its major components: pre-training of cohorts to prepare them for the research experience, joint weekly cohort activities throughout the research summer, peer- and multiple mentoring, weekly discussion of various aspects of professional and career development, continued engagement of students in science after return to home institution and lifelong mentoring. The mentors also form a cohort, exchanging information and learning from each other. With its partner institutions, the NAC aims to build a complete pipeline from undergraduate through career for the next generation of scientists and engineers. Our annual goal is to create two to three cohorts of four to five students at each site (currently NRAO-Charlottesville, NRAO-Socorro and U. Wisconsin - Madison). Recruitment occurs in the fall semester with seminars and colloquia in partnership with faculty at the minority serving institutions and the GRAD-MAP program at the University of Maryland. In this talk we describe in detail all the components of the NAC and report on our progress. We are keen to interact and partner with new universities and institutions and encourage them to contact the NAC at nac4stem@googlegroups.com.

NASA Astrophysics Data System (ADS)

Russell, Melody L.; Atwater, Mary M.

2005-08-01

This study focuses on 11 African American undergraduate seniors in a biology degree program at a predominantly white research institution in the southeastern United States. These 11 respondents shared their journeys throughout the high school and college science pipeline. Participants described similar precollege factors and experiences that contributed to their academic success and persistence at a predominantly white institution. One of the most critical factors in their academic persistence was participation in advanced science and mathematics courses as part of their high school college preparatory program. Additional factors that had a significant impact on their persistence and academic success were family support, teacher encouragement, intrinsic motivation, and perseverance.

The Rural Girls in Science Project: from Pipelines to Affirming Science Education

Ginorio, Angela B.; Huston, Michelle; Frevert, Katie; Seibel, Jane Bierman

The Rural Girls in Science (RGS) program was developed to foster the interest in science, engineering, and mathematics among rural high school girls in the state of Washington. Girls served include American Indians, Latinas, and Whites. This article provides an overview of the program and its outcomes not only for the participants (girls, teachers, counselors, and schools) but the researchers. Lessons learned from and about the participants are presented, and lessons learned from the process are discussed to illustrate how RGS moved from a focus on individuals to a focus on the school. The initial guiding concepts (self-esteem and scientific pipeline) were replaced by “possible selves” and our proposed complementary concepts: science-affirming and affirming science education.

Advancements in automated tissue segmentation pipeline for contrast-enhanced CT scans of adult and pediatric patients

Somasundaram, Elanchezhian; Kaufman, Robert; Brady, Samuel

2017-03-01

The development of a random forests machine learning technique is presented for fully-automated neck, chest, abdomen, and pelvis tissue segmentation of CT images using Trainable WEKA (Waikato Environment for Knowledge Analysis) Segmentation (TWS) plugin of FIJI (ImageJ, NIH). The use of a single classifier model to segment six tissue classes (lung, fat, muscle, solid organ, blood/contrast agent, bone) in the CT images is studied. An automated unbiased scheme to sample pixels from the training images and generate a balanced training dataset over the seven classes is also developed. Two independent training datasets are generated from a pool of 4 adult (>55 kg) and 3 pediatric patients (<=55 kg) with 7 manually contoured slices for each patient. Classifier training investigated 28 image filters comprising a total of 272 features. Highly correlated and insignificant features are eliminated using Correlated Feature Subset (CFS) selection with Best First Search (BFS) algorithms in WEKA. The 2 training models (from the 2 training datasets) had 74 and 71 input training features, respectively. The study also investigated the effect of varying the number of trees (25, 50, 100, and 200) in the random forest algorithm. The performance of the 2 classifier models are evaluated on inter-patient intra-slice, intrapatient inter-slice and inter-patient inter-slice test datasets. The Dice similarity coefficients (DSC) and confusion matrices are used to understand the performance of the classifiers across the tissue segments. The effect of number of features in the training input on the performance of the classifiers for tissue classes with less than optimal DSC values is also studied. The average DSC values for the two training models on the inter-patient intra-slice test data are: 0.98, 0.89, 0.87, 0.79, 0.68, and 0.84, for lung, fat, muscle, solid organ, blood/contrast agent, and bone, respectively. The study demonstrated that a robust segmentation accuracy for lung, muscle and fat tissue classes. For solid-organ, blood/contrast and bone, the performance of the segmentation pipeline improved significantly by using the advanced capabilities of WEKA. However, further improvements are needed to reduce the noise in the segmentation.

Leakage Risk Assessment of CO{sub 2} Transportation by Pipeline at the Illinois Basin Decatur Project, Decatur, Illinois

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

Mazzoldi, A.; Oldenburg, C. M.

The Illinois Basin Decatur Project (IBDP) is designed to confirm the ability of the Mt. Simon Sandstone, a major regional saline-water-bearing formation in the Illinois Basin, to store 1 million tons of carbon dioxide (CO{sub 2}) injected over a period of three years. The CO{sub 2} will be provided by Archer Daniels Midland (ADM) from its Decatur, Illinois, ethanol plant. In order to transport CO{sub 2} from the capture facility to the injection well (also located within the ADM plant boundaries), a high-pressure pipeline of length 3,200 ft (975 m) has been constructed, running above the ground surface within themore » ADM plant footprint. We have qualitatively evaluated risks associated with possible pipeline failure scenarios that lead to discharge of CO{sub 2} within the real-world environment of the ADM plant in which there are often workers and visitors in the vicinity of the pipeline. There are several aspects of CO{sub 2} that make its transportation and potential leakage somewhat different from other substances, most notable is its non-flammability and propensity to change to solid (dry ice) upon strong decompression. In this study, we present numerical simulations using Computational Fluid Dynamics (CFD) methods of the release and dispersion of CO{sub 2} from individual hypothetical pipeline failures (i.e., leaks). Failure frequency of the various components of a pipeline transportation system over time are taken from prior work on general pipeline safety and leakage modeling and suggest a 4.65% chance of some kind of pipeline failure over the three-years of operation. Following the Precautionary Principle (see below), we accounted for full-bore leakage scenarios, where the temporal evolution of the mass release rate from the high-pressure pipeline leak locations was simulated using a state-of-the-art Pipe model which considers the thermodynamic effects of decompression in the entire pipeline. Failures have been simulated at four representative locations along the pipeline route within the ADM plant. Leakage scenarios at sites along the route of the pipeline, where plant operations (e.g., vehicular and train transportation) seem to present a higher likelihood of accidental failure, for example due to vehicles or equipment crashing into the pipeline and completely severing it, were modeled by allowing them to have a double source consistent with the pipeline releasing high-pressure CO{sub 2} from both ends of the broken pipe after a full-bore offset rupture. Simulation results show that the built environment of the plant plays a significant role in the dispersion of the gas as leaking CO{sub 2} can impinge upon buildings and other infrastructure. In all scenarios simulated, the region of very high-concentration of CO{sub 2} is limited to a small area around the pipeline failure, suggesting the likelihood of widespread harmful CO{sub 2} exposure to plant personnel from pipeline leakage is low. An additional risk is posed by the blast wave that emanates from a high-pressure pipeline when it is breached quickly. We estimate the blast wave risk as low because it occurs only for a short time in the immediate vicinity of the rupture, and requires an instantaneous large-scale rupture to occur. We recommend consideration of signage and guard rails and posts to mitigate the likelihood of vehicles crashing into the pipeline. A standardized emergency response plan applicable to capture plants within industrial sites could be developed based on the IBDP that would be useful for other capture plants. Finally, we recommend carrying out coupled wellbore-reservoir blowout scenario modeling to understand the potential for hazardous conditions arising from an unexpected blowout at the wellhead.« less

Diversifying the Health-Care Workforce Begins at the Pipeline: A 5-Year Synthesis of Processes and Outputs of the Scholarships for Disadvantaged Students Program.

Camacho, Alex; Zangaro, George; White, Kathleen M

2015-12-09

The case for a more diverse health-care workforce has never been stronger given the rapidly changing demographics of the United States and the continued underrepresentation of certain racial and ethnic groups across the health professions. To date, progress toward diversifying the health-care workforce has been and continues to be deterred by a mix of factors at the societal, institutional, and individual levels. Since the 1970s, the Federal government has invested resources in initiatives that support the training and development of the existing workforce as well increase the supply of new health professionals-particularly those from underrepresented minority groups and/or from disadvantaged backgrounds. However, limited studies have been published detailing the processes, outputs and, where available, outcomes of such investments across multiple years. This article describes how the Health Resources and Services Administration's Bureau of Health Workforce used retrospective case study methodology to evaluate processes and outputs associated with the Scholarships for Disadvantaged Students program-an over US$40 million annual Federal investment aimed at offsetting tuition costs for health professions students from disadvantaged backgrounds-over a 5-year period. Lessons learned and recommendations for strengthening the program's design and requirements are provided. © The Author(s) 2015.

A Concept for the One Degree Imager (ODI) Data Reduction Pipeline and Archiving System

NASA Astrophysics Data System (ADS)

Knezek, Patricia; Stobie, B.; Michael, S.; Valdes, F.; Marru, S.; Henschel, R.; Pierce, M.

2010-05-01

The One Degree Imager (ODI), currently being built by the WIYN Observatory, will provide tremendous possibilities for conducting diverse scientific programs. ODI will be a complex instrument, using non-conventional Orthogonal Transfer Array (OTA) detectors. Due to its large field of view, small pixel size, use of OTA technology, and expected frequent use, ODI will produce vast amounts of astronomical data. If ODI is to achieve its full potential, a data reduction pipeline must be developed. Long-term archiving must also be incorporated into the pipeline system to ensure the continued value of ODI data. This paper presents a concept for an ODI data reduction pipeline and archiving system. To limit costs and development time, our plan leverages existing software and hardware, including existing pipeline software, Science Gateways, Computational Grid & Cloud Technology, Indiana University's Data Capacitor and Massive Data Storage System, and TeraGrid compute resources. Existing pipeline software will be augmented to add functionality required to meet challenges specific to ODI, enhance end-user control, and enable the execution of the pipeline on grid resources including national grid resources such as the TeraGrid and Open Science Grid. The planned system offers consistent standard reductions and end-user flexibility when working with images beyond the initial instrument signature removal. It also gives end-users access to computational and storage resources far beyond what are typically available at most institutions. Overall, the proposed system provides a wide array of software tools and the necessary hardware resources to use them effectively.

2006-12-01

Our undergraduate research program, SCEC/UseIT, an NSF Research Experience for Undergraduates site, provides software for earthquake researchers and educators, movies for outreach, and ways to strengthen the technical career pipeline. SCEC/UseIT motivates diverse undergraduates towards science and engineering careers through team-based research in the exciting field of earthquake information technology. UseIT provides the cross-training in computer science/information technology (CS/IT) and geoscience needed to make fundamental progress in earthquake system science. Our high and increasing participation of women and minority students is crucial given the nation"s precipitous enrollment declines in CS/IT undergraduate degree programs, especially among women. UseIT also casts a "wider, farther" recruitment net that targets scholars interested in creative work but not traditionally attracted to summer science internships. Since 2002, SCEC/UseIT has challenged 79 students in three dozen majors from as many schools with difficult, real-world problems that require collaborative, interdisciplinary solutions. Interns design and engineer open-source software, creating increasingly sophisticated visualization tools (see "SCEC-VDO," session IN11), which are employed by SCEC researchers, in new curricula at the University of Southern California, and by outreach specialists who make animated movies for the public and the media. SCEC-VDO would be a valuable tool for research-oriented professional development programs.

a Fully Automated Pipeline for Classification Tasks with AN Application to Remote Sensing

NASA Astrophysics Data System (ADS)

Suzuki, K.; Claesen, M.; Takeda, H.; De Moor, B.

2016-06-01

Nowadays deep learning has been intensively in spotlight owing to its great victories at major competitions, which undeservedly pushed `shallow' machine learning methods, relatively naive/handy algorithms commonly used by industrial engineers, to the background in spite of their facilities such as small requisite amount of time/dataset for training. We, with a practical point of view, utilized shallow learning algorithms to construct a learning pipeline such that operators can utilize machine learning without any special knowledge, expensive computation environment, and a large amount of labelled data. The proposed pipeline automates a whole classification process, namely feature-selection, weighting features and the selection of the most suitable classifier with optimized hyperparameters. The configuration facilitates particle swarm optimization, one of well-known metaheuristic algorithms for the sake of generally fast and fine optimization, which enables us not only to optimize (hyper)parameters but also to determine appropriate features/classifier to the problem, which has conventionally been a priori based on domain knowledge and remained untouched or dealt with naïve algorithms such as grid search. Through experiments with the MNIST and CIFAR-10 datasets, common datasets in computer vision field for character recognition and object recognition problems respectively, our automated learning approach provides high performance considering its simple setting (i.e. non-specialized setting depending on dataset), small amount of training data, and practical learning time. Moreover, compared to deep learning the performance stays robust without almost any modification even with a remote sensing object recognition problem, which in turn indicates that there is a high possibility that our approach contributes to general classification problems.

2008-01-01

The Helioseismic and Magnetic Imager of SDO will provide uninterrupted 4k x 4k-pixel Doppler-shift images of the Sun with approximately 40 sec cadence. These data will have a unique potential for advancing local helioseismic diagnostics of the Sun's interior structure and dynamics. They will help to understand the basic mechanisms of solar activity and develop predictive capabilities for NASA's Living with a Star program. Because of the tremendous amount of data the HMI team is developing a data analysis pipeline, which will provide maps of subsurface flows and sound-speed distributions inferred form the Doppler data by the time-distance technique. We discuss the development plan, methods, and algorithms, and present the status of the pipeline, testing results and examples of the data products.

A pipeline of programs for collecting and analyzing group II intron retroelement sequences from GenBank

PubMed Central

2013-01-01

Background Accurate and complete identification of mobile elements is a challenging task in the current era of sequencing, given their large numbers and frequent truncations. Group II intron retroelements, which consist of a ribozyme and an intron-encoded protein (IEP), are usually identified in bacterial genomes through their IEP; however, the RNA component that defines the intron boundaries is often difficult to identify because of a lack of strong sequence conservation corresponding to the RNA structure. Compounding the problem of boundary definition is the fact that a majority of group II intron copies in bacteria are truncated. Results Here we present a pipeline of 11 programs that collect and analyze group II intron sequences from GenBank. The pipeline begins with a BLAST search of GenBank using a set of representative group II IEPs as queries. Subsequent steps download the corresponding genomic sequences and flanks, filter out non-group II introns, assign introns to phylogenetic subclasses, filter out incomplete and/or non-functional introns, and assign IEP sequences and RNA boundaries to the full-length introns. In the final step, the redundancy in the data set is reduced by grouping introns into sets of ≥95% identity, with one example sequence chosen to be the representative. Conclusions These programs should be useful for comprehensive identification of group II introns in sequence databases as data continue to rapidly accumulate. PMID:24359548

What role can the rural pipeline play in the recruitment and retention of rural allied health professionals?

PubMed

Durey, Angela; Haigh, Margaret; Katzenellenbogen, Judith M

2015-01-01

People living in rural areas have poorer health than their urban counterparts with higher morbidity and mortality rates and lower life expectancy. Challenges attracting health professionals to work in rural locations in Australia and elsewhere have been well- documented. In response, the idea of a rural pipeline emerged in the medical literature as a career pathway for doctors, conceptualised as a career continuum starting at school and ending in a committed, appropriately trained and supported rural doctor. This article draws on the literature to consider how the concept of a rural pipeline can be used to enhance recruitment and retention of allied health professionals (AHPs) in Australia. The complexity of the issue is taken into account, acknowledging the diverse professional, organisational and social needs within and between AHPs and their different career pathways. With this in mind, the rural pipeline is adapted and extended to focus on AHPs who enter at any stage of their career to work in rural areas. Barriers to recruitment and retention require multifaceted strategies to encourage and support AHPs at various stages along the pipeline to enter, and remain in, rural practice. Findings from the literature identify discrete themes within and between AHPs about factors influencing their rural recruitment and retention choices and include career stage at entry to rural practice, age, gender, social context, professional support, organisational environment and public-private practice mix in service delivery. These findings underscored the development of an extended rural pipeline adapted to specifically target AHPs. This flexible framework of entry to rural practice can be applied at any stage of their career and includes suggestions of strategies to support retention. Evidence from studies of rural AHPs suggests a flexible approach to recruitment and retention is needed that takes into account the complexity of the issue. The extended rural pipeline adapted to AHPs avoids a one-size-fits-all approach. Instead, it offers a more nuanced approach that addresses the diversity within and between professions and reflects the different stages at which AHPs enter rural practice that can inform recruitment and retention strategies that better meet their needs.

TH-AB-207A-05: A Fully-Automated Pipeline for Generating CT Images Across a Range of Doses and Reconstruction Methods

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

Young, S; Lo, P; Hoffman, J

Purpose: To evaluate the robustness of CAD or Quantitative Imaging methods, they should be tested on a variety of cases and under a variety of image acquisition and reconstruction conditions that represent the heterogeneity encountered in clinical practice. The purpose of this work was to develop a fully-automated pipeline for generating CT images that represent a wide range of dose and reconstruction conditions. Methods: The pipeline consists of three main modules: reduced-dose simulation, image reconstruction, and quantitative analysis. The first two modules of the pipeline can be operated in a completely automated fashion, using configuration files and running the modulesmore » in a batch queue. The input to the pipeline is raw projection CT data; this data is used to simulate different levels of dose reduction using a previously-published algorithm. Filtered-backprojection reconstructions are then performed using FreeCT-wFBP, a freely-available reconstruction software for helical CT. We also added support for an in-house, model-based iterative reconstruction algorithm using iterative coordinate-descent optimization, which may be run in tandem with the more conventional recon methods. The reduced-dose simulations and image reconstructions are controlled automatically by a single script, and they can be run in parallel on our research cluster. The pipeline was tested on phantom and lung screening datasets from a clinical scanner (Definition AS, Siemens Healthcare). Results: The images generated from our test datasets appeared to represent a realistic range of acquisition and reconstruction conditions that we would expect to find clinically. The time to generate images was approximately 30 minutes per dose/reconstruction combination on a hybrid CPU/GPU architecture. Conclusion: The automated research pipeline promises to be a useful tool for either training or evaluating performance of quantitative imaging software such as classifiers and CAD algorithms across the range of acquisition and reconstruction parameters present in the clinical environment.

Objective As part of the National MCH Workforce Development Center, an innovative internship program placed MCH undergraduate and graduate students in summer practica in state Title V agencies. Graduate student mentoring of undergraduates and leadership and professional development training and support are key features of the program. The objective of this paper is to report on the results of the evaluation of the MCH Paired Practica Program in its pilot years, 2014-2016. Methods Students completed pre and post internship questionnaires which included closed as well as open-ended questions. In addition, the Title V state health agency preceptors completed a questionnaire at the end of each summer. Results Over the 3-year pilot project, a total of 17 teams participated. Students were from 6 of the 13 graduate Centers of Excellence in MCH programs in Schools of Public Health and two undergraduate MCH Pipeline Programs. There were 11 participating states. After the practicum experience, there was a significant increase in students' confidence in a number of measures related to working in complex, dynamic environments and in their ability to contribute to improvements in MCH population health. Students reported having more confidence in their ability to function effectively as an informal/formal MCH leader (p = 0.02), more confidence in their ability to contribute to improvements in MCH population health (p = 0.04), and being more prepared to enter the workforce after the practicum experience (p = 0.07), although there was no significant change in students' (n = 22) interest in seeking a job in a Title V agency or a community based organization with a MCH focus. Nearly 60% of the students did state at the posttest that they would likely seek additional education in MCH. Overall, the Title V preceptors (n = 14) were very positive about the program although in some instances there was less confidence in the knowledge and skills of the undergraduate students. Conclusion The MCH Paired Practica Program is a unique effort to go beyond the academic training of undergraduate and graduate MCH students to provide them with direct exposure to the field, as well as leadership, mentorship, and professional development training. While some challenges emerged related to differences in skills between undergraduates and graduate MCH students, participating students demonstrated clear improvements in their leadership skills including increased confidence in their ability to take initiative, provide opinions and feedback, to function informally or formally as leaders, and to contribute to improvements in MCH population health.

Purpose: The purpose of this article is to share experiences after the development of a health-system pharmacy administration residency with a MS degree and express the need for additional programs in nonacademic medical center health-system settings. Summary: Experiences with the development and implementation of a health-system pharmacy administration residency at a large community teaching hospital are described. Resident candidates benefit from collaborations with other health-systems through master's degree programs and visibility to leaders at your health-system. Programs benefit from building a pipeline of future pharmacy administrators and by leveraging the skills of residents to contribute to projects and department-wide initiatives. Tools to assist in the implementation of a new pharmacy administration program are also described and include rotation and preceptor development, marketing and recruiting, financial evaluation, and steps to prepare for accreditation. Conclusion: Health-system pharmacy administration residents provide the opportunity to build a pipeline of high-quality leaders, provide high-level project involvement, and produce a positive return on investment (ROI) for health-systems. These programs should be explored in academic and nonacademic-based health-systems.

To expand the St. Fergus gas-reception terminal for the Scottish Area Gas Evacuation (SAGE) system, Mobil North Sea Ltd. is adding a second separation train and two treatment trains. To meet pipeline-gas specifications over a wide range of low rates and feed-gas compositions, single-stage turboexpander chilling was selected over Joule-Thomson valve expansion. Four turboexpanders (two per process train) will operate in parallel to achieve the required performance over the entire flow range of 90--575 MMscfd per process train. Unusual operating conditions for the turboexpanders include dense-phase inlet gas, expansion near the cricondenbar, and high equilibrium liquid content at the exhaustmore » (up to 50 wt %). The two turboexpanders in each train share common suction and discharge facilities as do their associated brake compressor.

Microbial genotyping increasingly deals with large numbers of samples, and data are commonly evaluated by unstructured approaches, such as spread-sheets. The efficiency, reliability and throughput of genotyping would benefit from the automation of manual manipulations within the context of sophisticated data storage. We developed a medium- throughput genotyping pipeline for MultiLocus Sequence Typing (MLST) of bacterial pathogens. This pipeline was implemented through a combination of four automated liquid handling systems, a Laboratory Information Management System (LIMS) consisting of a variety of dedicated commercial operating systems and programs, including a Sample Management System, plus numerous Python scripts. All tubes and microwell racks were bar-coded and their locations and status were recorded in the LIMS. We also created a hierarchical set of items that could be used to represent bacterial species, their products and experiments. The LIMS allowed reliable, semi-automated, traceable bacterial genotyping from initial single colony isolation and sub-cultivation through DNA extraction and normalization to PCRs, sequencing and MLST sequence trace evaluation. We also describe robotic sequencing to facilitate cherrypicking of sequence dropouts. This pipeline is user-friendly, with a throughput of 96 strains within 10 working days at a total cost of < €25 per strain. Since developing this pipeline, >200,000 items were processed by two to three people. Our sophisticated automated pipeline can be implemented by a small microbiology group without extensive external support, and provides a general framework for semi-automated bacterial genotyping of large numbers of samples at low cost.

Ground vibrations induced by blasting in the cement quarries are one of the fundamental problems in the quarrying industry and may cause severe damage to the nearby utilities and pipelines. Therefore, a vibration control study plays an important role in the minimization of environmental effects of blasting in quarries. The current paper presents the influence of the quarry blasts at the National Cement Company (NCC) on the two oil pipelines of SUMED Company southeast of Helwan City, by measuring the ground vibrations in terms of Peak Particle Velocity (PPV). The seismic refraction for compressional waves deduced from the shallow seismic survey and the shear wave velocity obtained from the Multi channel Analysis of Surface Waves (MASW) technique are used to evaluate the closest site of the two pipelines to the quarry blasts. The results demonstrate that, the closest site of the two pipelines is of class B, according to the National Earthquake Hazard Reduction Program (NEHRP) classification and the safe distance to avoid any environmental effects is 650 m, following the deduced Peak Particle Velocity (PPV) and scaled distance (SD) relationship (PPV = 700.08 × SD-1.225) in mm/s and the Air over Pressure (air blast) formula (air blast = 170.23 × SD-0.071) in dB. In the light of prediction analysis, the maximum allowable charge weight per delay was found to be 591 kg with damage criterion of 12.5 mm/s at the closest site of the SUMED pipelines.

To investigate the circumstances and geographic and temporal distributions of hazardous material releases and resulting human impacts in the United States. Releases with fatalities, injuries, and evacuations were identified from reports to the National Response Center between 1990 and 2008, correcting for data quality issues identified in previous studies. From more than 550,000 reports, 861 deaths, 16,348 injuries and 741,427 evacuations were identified. Injuries from releases of chemicals at fixed facilities and natural gas from pipelines have decreased whereas evacuations from petroleum releases at fixed facilities have increased. Results confirm recent advances in chemical and pipeline safety and suggest directions for further improvement including targeted training and inspections and adoption of inherently safer design principles.

Recent advances in big data analytics provide more flexible, efficient, and open tools for researchers to gain insight from healthcare data. Whilst many tools require researchers to develop programs with programming languages like Python, R and so on, which is not a skill set grasped by many researchers in the healthcare data analytics area. To make data science more approachable, we explored existing tools and developed a practice that can help data scientists convert existing analytics pipelines to user-friendly analytics APPs with rich interactions and features of real-time analysis. With this practice, data scientists can develop customized analytics pipelines as APPs in Jupyter Notebook and disseminate them to other researchers easily, and researchers can benefit from the shared notebook to perform analysis tasks or reproduce research results much more easily.

RGAugury: a pipeline for genome-wide prediction of resistance gene analogs (RGAs) in plants.

2016-11-02

Resistance gene analogs (RGAs), such as NBS-encoding proteins, receptor-like protein kinases (RLKs) and receptor-like proteins (RLPs), are potential R-genes that contain specific conserved domains and motifs. Thus, RGAs can be predicted based on their conserved structural features using bioinformatics tools. Computer programs have been developed for the identification of individual domains and motifs from the protein sequences of RGAs but none offer a systematic assessment of the different types of RGAs. A user-friendly and efficient pipeline is needed for large-scale genome-wide RGA predictions of the growing number of sequenced plant genomes. An integrative pipeline, named RGAugury, was developed to automate RGA prediction. The pipeline first identifies RGA-related protein domains and motifs, namely nucleotide binding site (NB-ARC), leucine rich repeat (LRR), transmembrane (TM), serine/threonine and tyrosine kinase (STTK), lysin motif (LysM), coiled-coil (CC) and Toll/Interleukin-1 receptor (TIR). RGA candidates are identified and classified into four major families based on the presence of combinations of these RGA domains and motifs: NBS-encoding, TM-CC, and membrane associated RLP and RLK. All time-consuming analyses of the pipeline are paralleled to improve performance. The pipeline was evaluated using the well-annotated Arabidopsis genome. A total of 98.5, 85.2, and 100 % of the reported NBS-encoding genes, membrane associated RLPs and RLKs were validated, respectively. The pipeline was also successfully applied to predict RGAs for 50 sequenced plant genomes. A user-friendly web interface was implemented to ease command line operations, facilitate visualization and simplify result management for multiple datasets. RGAugury is an efficiently integrative bioinformatics tool for large scale genome-wide identification of RGAs. It is freely available at Bitbucket: https://bitbucket.org/yaanlpc/rgaugury .

The Kepler Mission was launched in 2009 as NASAs first mission capable of finding Earth-size planets in the habitable zone of Sun-like stars. Its telescope consists of a 1.5-m primary mirror and a 0.95-m aperture. The 42 charge-coupled devices in its focal plane are read out every half hour, compressed, and then downlinked monthly. After four years, the second of four reaction wheels failed, ending the original mission. Back on earth, the Science Operations Center developed the Science Pipeline to analyze about 200,000 target stars in Keplers field of view, looking for evidence of periodic dimming suggesting that one or more planets had crossed the face of its host star. The Pipeline comprises several steps, from pixel-level calibration, through noise and artifact removal, to detection of transit-like signals and the construction of a suite of diagnostic tests to guard against false positives. The Kepler Science Pipeline consists of a pipeline infrastructure written in the Java programming language, which marshals data input to and output from MATLAB applications that are executed as external processes. The pipeline modules, which underwent continuous development and refinement even after data started arriving, employ several analytic techniques, many developed for the Kepler Project. Because of the large number of targets, the large amount of data per target and the complexity of the pipeline algorithms, the processing demands are daunting. Some pipeline modules require days to weeks to process all of their targets, even when run on NASA's 128-node Pleiades supercomputer. The software developers are still seeking ways to increase the throughput. To date, the Kepler project has discovered more than 4000 planetary candidates, of which more than 1000 have been independently confirmed or validated to be exoplanets. Funding for this mission is provided by NASAs Science Mission Directorate.

Navigating the science, technology, engineering, and mathematics pipeline: How social capital impacts the educational attainment of college-bound female students

NASA Astrophysics Data System (ADS)

Lee, Rebecca Elizabeth

Despite the proliferation of women in higher education and the workforce, they have yet to achieve parity with men in many of the science, technology, engineering, and math (STEM) majors and careers. The gap is even greater in the representation of women from lower socioeconomic backgrounds. This study examined pre-college intervention strategies provided by the University of Southern California's Math, Engineering, Science Achievement (MESA) program, as well as the relationships and experiences that contributed to the success of underrepresented female high school students in the STEM pipeline. A social capital framework provided the backdrop to the study. This qualitative study takes an ethnographic approach, incorporating 11 interviews, 42 hours of observation, and document analysis to address the research questions: How does involvement in the MESA program impact female students' decisions to pursue a mathematics or science major in college? What is the role of significant others in supporting and encouraging student success? The findings revealed a continuous cycle of support for these students. The cycle started in the home environment, where parents were integral in the early influence on the students' decisions to pursue higher education. Relationships with teachers, counselors, and peers provided critical networks of support in helping these students to achieve their academic goals. Participation in the MESA program empowered the students and provided additional connections to knowledge-based resources. This study highlights the interplay among family, school, and the MESA program in the overall support of underrepresented female students in the STEM pipeline.

In this study, quantitative structure-activity relationship (QSAR) models using various descriptor sets and training/test set selection methods were explored to predict the bioactivity of hepatitis C virus (HCV) NS3/4A protease inhibitors by using a multiple linear regression (MLR) and a support vector machine (SVM) method. 512 HCV NS3/4A protease inhibitors and their IC 50 values which were determined by the same FRET assay were collected from the reported literature to build a dataset. All the inhibitors were represented with selected nine global and 12 2D property-weighted autocorrelation descriptors calculated from the program CORINA Symphony. The dataset was divided into a training set and a test set by a random and a Kohonen's self-organizing map (SOM) method. The correlation coefficients (r 2 ) of training sets and test sets were 0.75 and 0.72 for the best MLR model, 0.87 and 0.85 for the best SVM model, respectively. In addition, a series of sub-dataset models were also developed. The performances of all the best sub-dataset models were better than those of the whole dataset models. We believe that the combination of the best sub- and whole dataset SVM models can be used as reliable lead designing tools for new NS3/4A protease inhibitors scaffolds in a drug discovery pipeline.

2007-01-01

Background Expression of higher eukaryotic genes as soluble, stable recombinant proteins is still a bottleneck step in biochemical and structural studies of novel proteins today. Correct identification of stable domains/fragments within the open reading frame (ORF), combined with proper cloning strategies, can greatly enhance the success rate when higher eukaryotic proteins are expressed as these domains/fragments. Furthermore, a HTP cloning pipeline incorporated with bioinformatics domain/fragment selection methods will be beneficial to studies of structure and function genomics/proteomics. Results With bioinformatics tools, we developed a domain/domain boundary prediction (DDBP) method, which was trained by available experimental data. Combined with an improved cloning strategy, DDBP had been applied to 57 proteins from C. elegans. Expression and purification results showed there was a 10-fold increase in terms of obtaining purified proteins. Based on the DDBP method, the improved GATEWAY cloning strategy and a robotic platform, we constructed a high throughput (HTP) cloning pipeline, including PCR primer design, PCR, BP reaction, transformation, plating, colony picking and entry clones extraction, which have been successfully applied to 90 C. elegans genes, 88 Brucella genes, and 188 human genes. More than 97% of the targeted genes were obtained as entry clones. This pipeline has a modular design and can adopt different operations for a variety of cloning/expression strategies. Conclusion The DDBP method and improved cloning strategy were satisfactory. The cloning pipeline, combined with our recombinant protein HTP expression pipeline and the crystal screening robots, constitutes a complete platform for structure genomics/proteomics. This platform will increase the success rate of purification and crystallization dramatically and promote the further advancement of structure genomics/proteomics. PMID:17663785

A novel strategy for classifying the output from an in silico vaccine discovery pipeline for eukaryotic pathogens using machine learning algorithms.

PubMed

Goodswen, Stephen J; Kennedy, Paul J; Ellis, John T

2013-11-02

An in silico vaccine discovery pipeline for eukaryotic pathogens typically consists of several computational tools to predict protein characteristics. The aim of the in silico approach to discovering subunit vaccines is to use predicted characteristics to identify proteins which are worthy of laboratory investigation. A major challenge is that these predictions are inherent with hidden inaccuracies and contradictions. This study focuses on how to reduce the number of false candidates using machine learning algorithms rather than relying on expensive laboratory validation. Proteins from Toxoplasma gondii, Plasmodium sp., and Caenorhabditis elegans were used as training and test datasets. The results show that machine learning algorithms can effectively distinguish expected true from expected false vaccine candidates (with an average sensitivity and specificity of 0.97 and 0.98 respectively), for proteins observed to induce immune responses experimentally. Vaccine candidates from an in silico approach can only be truly validated in a laboratory. Given any in silico output and appropriate training data, the number of false candidates allocated for validation can be dramatically reduced using a pool of machine learning algorithms. This will ultimately save time and money in the laboratory.

2013-07-01

The Digital Access to a Sky Century@Harvard (DASCH) project is digitizing the ˜500,000 glass plate images obtained (full sky) by the Harvard College Observatory from 1885 to 1992. Astrometry and photometry for each resolved object are derived with photometric rms values of ˜0.15 mag for the initial photometry analysis pipeline. Here we describe new developments for DASCH photometry, applied to the Kepler field, that have yielded further improvements, including better identification of image blends and plate defects by measuring image profiles and astrometric deviations. A local calibration procedure using nearby stars in a similar magnitude range as the program star (similar to what has been done for visual photometry from the plates) yields additional improvement for a net photometric rms of ˜0.1 mag. We also describe statistical measures of light curves that are now used in the DASCH pipeline processing to identify new variables autonomously. The DASCH photometry methods described here are used in the pipeline processing for the data releases of DASCH data,5 as well as for a forthcoming paper on the long-term variables discovered by DASCH in the Kepler field.

Automated protein structure modeling in CASP9 by I-TASSER pipeline combined with QUARK-based ab initio folding and FG-MD-based structure refinement

Xu, Dong; Zhang, Jian; Roy, Ambrish; Zhang, Yang

2011-01-01

I-TASSER is an automated pipeline for protein tertiary structure prediction using multiple threading alignments and iterative structure assembly simulations. In CASP9 experiments, two new algorithms, QUARK and FG-MD, were added to the I-TASSER pipeline for improving the structural modeling accuracy. QUARK is a de novo structure prediction algorithm used for structure modeling of proteins that lack detectable template structures. For distantly homologous targets, QUARK models are found useful as a reference structure for selecting good threading alignments and guiding the I-TASSER structure assembly simulations. FG-MD is an atomic-level structural refinement program that uses structural fragments collected from the PDB structures to guide molecular dynamics simulation and improve the local structure of predicted model, including hydrogen-bonding networks, torsion angles and steric clashes. Despite considerable progress in both the template-based and template-free structure modeling, significant improvements on protein target classification, domain parsing, model selection, and ab initio folding of beta-proteins are still needed to further improve the I-TASSER pipeline.

Hintermüller, C; Marone, F; Isenegger, A; Stampanoni, M

2010-07-01

With synchrotron-radiation-based tomographic microscopy, three-dimensional structures down to the micrometer level can be visualized. Tomographic data sets typically consist of 1000 to 1500 projections of 1024 x 1024 to 2048 x 2048 pixels and are acquired in 5-15 min. A processing pipeline has been developed to handle this large amount of data efficiently and to reconstruct the tomographic volume within a few minutes after the end of a scan. Just a few seconds after the raw data have been acquired, a selection of reconstructed slices is accessible through a web interface for preview and to fine tune the reconstruction parameters. The same interface allows initiation and control of the reconstruction process on the computer cluster. By integrating all programs and tools, required for tomographic reconstruction into the pipeline, the necessary user interaction is reduced to a minimum. The modularity of the pipeline allows functionality for new scan protocols to be added, such as an extended field of view, or new physical signals such as phase-contrast or dark-field imaging etc.

Automated image processing techniques have the potential to aid in the performance evaluation of nuclear fuels by eliminating judgment calls that may vary from person-to-person or sample-to-sample. Analysis of in-core fuel performance is required for design and safety evaluations related to almost every aspect of the nuclear fuel cycle. This study presents a methodology for assessing the quality of uranium–molybdenum fuel images and describes image analysis routines designed for the characterization of several important microstructural properties. The analyses are performed in CellProfiler, an open-source program designed to enable biologists without training in computer vision or programming to automatically extract cellularmore » measurements from large image sets. The quality metric scores an image based on three parameters: the illumination gradient across the image, the overall focus of the image, and the fraction of the image that contains scratches. The metric presents the user with the ability to ‘pass’ or ‘fail’ an image based on a reproducible quality score. Passable images may then be characterized through a separate CellProfiler pipeline, which enlists a variety of common image analysis techniques. The results demonstrate the ability to reliably pass or fail images based on the illumination, focus, and scratch fraction of the image, followed by automatic extraction of morphological data with respect to fission gas voids, interaction layers, and grain boundaries. - Graphical abstract: Display Omitted - Highlights: • A technique is developed to score U–10Mo FIB-SEM image quality using CellProfiler. • The pass/fail metric is based on image illumination, focus, and area scratched. • Automated image analysis is performed in pipeline fashion to characterize images. • Fission gas void, interaction layer, and grain boundary coverage data is extracted. • Preliminary characterization results demonstrate consistency of the algorithm.« less

A gender gap in the next generation of physician-scientists: medical student interest and participation in research.

For 2 decades, the number of physician-scientists has not kept pace with the overall growth of the medical research community. Concomitantly, the number of women entering medical schools has increased markedly. We have explored the effect of the changing gender composition of medical schools on the present and future pipeline of young physician-scientists. We analyzed data obtained from the Association of American Medical Colleges, the National Institutes of Health, and the Howard Hughes Medical Institute pertaining to the expressed research intentions or research participation of male and female medical students in the United States. A statistically significant decline in the percentage of matriculating and graduating medical students--both men and women-who expressed strong research career intentions occurred during the decade between 1987 and 1997. Moreover, matriculating and graduating women were significantly less likely than men to indicate strong research career intentions. Each of these trends has been observed for medical schools overall and for research-intensive ones. Cohort data obtained by tracking individuals from matriculation to graduation revealed that women who expressed strong research career intentions upon matriculation were more likely than men to decrease their research career intentions during medical school. Medical student participation in research supported the gender gap identified by assessing research intentions. Female medical student participation in the Medical Scientist Training Program and the Howard Hughes Medical Institute/National Institutes of Health-sponsored Cloisters Program has increased but lags far behind the growth in the female population in medical schools. Three worrisome trends in the research career intentions and participation of the nation's medical students (a decade-long decline for both men and women, a large and persistent gender gap, and a negative effect of the medical school experience for women) presage a further decline in the physician-scientist pipeline unless they are reversed promptly and decisively.

A Pipeline Tool for CCD Image Processing

Bell, Jon F.; Young, Peter J.; Roberts, William H.; Sebo, Kim M.

MSSSO is part of a collaboration developing a wide field imaging CCD mosaic (WFI). As part of this project, we have developed a GUI based pipeline tool that is an integrated part of MSSSO's CICADA data acquisition environment and processes CCD FITS images as they are acquired. The tool is also designed to run as a stand alone program to process previously acquired data. IRAF tasks are used as the central engine, including the new NOAO mscred package for processing multi-extension FITS files. The STScI OPUS pipeline environment may be used to manage data and process scheduling. The Motif GUI was developed using SUN Visual Workshop. C++ classes were written to facilitate launching of IRAF and OPUS tasks. While this first version implements calibration processing up to and including flat field corrections, there is scope to extend it to other processing.

Pharmaceutical new product development: the increasing role of in-licensing.

PubMed

Edwards, Nancy V

2008-12-01

Many pharmaceutical companies are facing a pipeline gap because of the increasing economic burden and uncertainty associated with internal research and development programs designed to develop new pharmaceutical products. To fill this pipeline gap, pharmaceutical companies are increasingly relying on in-licensing opportunities. New business development identifies new pharmaceuticals that satisfy unmet needs and are a good strategic fit for the company, completes valuation models and forecasts, evaluates the ability of the company to develop and launch products, and pursues in-licensing agreements for pharmaceuticals that cannot be developed internally on a timely basis. These agreements involve the transfer of access rights for patents, trademarks, or similar intellectual property from an outside company in exchange for payments. Despite the risks, in-licensing is increasingly becoming the preferred method for pharmaceutical companies with pipeline gaps to bring new pharmaceuticals to the clinician.

Kidney disease physician workforce: where is the emerging pipeline?

A predicted increase in the number of patients with end-stage renal disease in coming years, coupled with significant numbers of qualified nephrologists reaching retirement age, will place great demands on the renal physician workforce. Action is required on several fronts to combat the predicted shortfall in full-time nephrologists. Of particular importance is the need to recruit and train greater numbers of physicians from ethnic minority groups. Changes in the demographics of kidney disease make it increasingly a disease of ethnic minorities and the poor. These demographic changes, together with the existing racial disparities in the diagnosis and treatment of kidney disease, highlight the specific need for nephrologists who are cognizant of the issues and barriers that prevent optimal care of high-risk minority populations. The current lack of academic role models and the drive by medical schools and residency programs to encourage minority group physicians to become primary care providers, rather than specialists, are issues that must be urgently addressed. Equally, changes in the training of renal fellows are required to merge the critical need for cutting edge research activity in renal science and with the insights and sensitivity to equip clinicians with the necessary skills for the team-based approach to patient care that increasingly characterizes the management and care of the patient with chronic kidney disease.

Algorithms for parallel flow solvers on message passing architectures

NASA Technical Reports Server (NTRS)

Vanderwijngaart, Rob F.

1995-01-01

The purpose of this project has been to identify and test suitable technologies for implementation of fluid flow solvers -- possibly coupled with structures and heat equation solvers -- on MIMD parallel computers. In the course of this investigation much attention has been paid to efficient domain decomposition strategies for ADI-type algorithms. Multi-partitioning derives its efficiency from the assignment of several blocks of grid points to each processor in the parallel computer. A coarse-grain parallelism is obtained, and a near-perfect load balance results. In uni-partitioning every processor receives responsibility for exactly one block of grid points instead of several. This necessitates fine-grain pipelined program execution in order to obtain a reasonable load balance. Although fine-grain parallelism is less desirable on many systems, especially high-latency networks of workstations, uni-partition methods are still in wide use in production codes for flow problems. Consequently, it remains important to achieve good efficiency with this technique that has essentially been superseded by multi-partitioning for parallel ADI-type algorithms. Another reason for the concentration on improving the performance of pipeline methods is their applicability in other types of flow solver kernels with stronger implied data dependence. Analytical expressions can be derived for the size of the dynamic load imbalance incurred in traditional pipelines. From these it can be determined what is the optimal first-processor retardation that leads to the shortest total completion time for the pipeline process. Theoretical predictions of pipeline performance with and without optimization match experimental observations on the iPSC/860 very well. Analysis of pipeline performance also highlights the effect of uncareful grid partitioning in flow solvers that employ pipeline algorithms. If grid blocks at boundaries are not at least as large in the wall-normal direction as those immediately adjacent to them, then the first processor in the pipeline will receive a computational load that is less than that of subsequent processors, magnifying the pipeline slowdown effect. Extra compensation is needed for grid boundary effects, even if all grid blocks are equally sized.

The Effect of Corrosion on the Seismic Behavior of Buried Pipelines and a Remedy for Their Seismic Retrofit

NASA Astrophysics Data System (ADS)

Hosseini, Mahmood; Salek, Shamila; Moradi, Masoud

2008-07-01

The effect of corrosion phenomenon has been investigated by performing some sets of 3-Dimensional Nonlinear Time History Analysis (3-D NLTHA) in which soil structure interaction as well as wave propagation effects have been taken into consideration. The 3-D NLTHA has been performed by using a finite element computer program, and both states of overall and local corrosions have been considered for the study. The corrosion has been modeled in the computer program by introducing decreased values of either pipe wall thickness or modulus of elasticity and Poisson ratio. Three sets of 3-component accelerograms have been used in analyses, and some appropriate numbers of zeros have been added at the beginning of records to take into account the wave propagation in soil and its multi-support excitation effect. The soil has been modeled by nonlinear springs in longitudinal, lateral, and vertical directions. A relatively long segment of the pipeline has been considered for the study and the effect of end conditions has been investigated by assuming different kinds end supports for the segment. After studying the corroded pipeline, a remedy has been considered for the seismic retrofit of corroded pipe by using a kind of Fiber Reinforced Polymers (FRP) cover. The analyses have been repeated for the retrofitted pipeline to realize the adequacy of FRP cover. Numerical results show that if the length of the pipeline segment is large enough, comparing to the wave length of shear wave in the soil, the end conditions do not have any major effect on the maximum stress and strain values in the pipe. Results also show that corrosion can lead to the increase in plastic strain values in the pipe up to 4 times in the case of overall corrosion and up to 20 times in the case of local corrosion. The satisfactory effect of using FRP cover is also shown by the analyses results, which confirm the decrease of strain values to 1/3.

Creating a More Inclusive Talent Pool for the GeoSciences in NOAA Mission Fields:

NASA Astrophysics Data System (ADS)

Rousseau, J.; Trotman, A. A.

2014-12-01

The National Oceanic and Atmospheric Administration (NOAA) Educational Partnership Program (EPP) with Minority Serving Institutions (MSI) is recognized as a model federal Science, Technology, Engineering, and Mathematics, (STEM) education investment. The EPP has a premier goal of increasing the numbers of students, especially from underrepresented communities, who are trained and awarded degrees in NOAA mission-relevant STEM fields. This goal is being achieved through awards to support undergraduate and graduate level student scholarships and to enhance NOAA mission-relevant education, research and internships at EPP Cooperative Science Centers located at MSIs. The internships allow undergraduate students to gain technical experience in STEM fields while gaining an understanding of a science mission agency such as NOAA. EPP has built evidence supporting the value of internships with its Undergraduate Scholarship Program (USP). Program metrics are used to refine and improve the internship to ensure student success. Scholarships are competitively awarded and requires applicants to submit a personal statement detailing the NOAA-relevant professional experience the applicant seeks to acquire, and gauges the depth of understanding of the work of NOAA.A focus is the EPP USP Student Internship at NOAA, which has two training phases. The first occurs at NOAA HQ in Maryland and incorporates exposure to NOAA professional culture including mentoring and professional development for scholarship recipients. The second occurs at NOAA facilities in the 50 states and US Territories. The internship projects are conducted under the supervision of a NOAA mentor and allow the scholars to: acquire increased science and technology skills: be attached to a research group and participate in a research activity as part of the team; and, acquire practical experience and knowledge of the day-to-day work of the NOAA facility. EPP has recently initiated the Experiential Research and Training Opportunities (NERTO) for students from the CSCs. The NERTO is a longer term immersion at NOAA facilities, with a NOAA mentor working collaboratively with their academic advisor on a NOAA science priority. Consequently, the NERTO is strengthening the undergraduate to graduate education and workforce pipeline.

SPACE WARPS- II. New gravitational lens candidates from the CFHTLS discovered through citizen science

We report the discovery of 29 promising (and 59 total) new lens candidates from the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) based on about 11 million classifications performed by citizen scientists as part of the first SPACE WARPS lens search. The goal of the blind lens search was to identify lens candidates missed by robots (the RINGFINDER on galaxy scales and ARCFINDER on group/cluster scales) which had been previously used to mine the CFHTLS for lenses. We compare some properties of the samples detected by these algorithms to the SPACE WARPS sample and find them to be broadly similar. The image separation distribution calculated from the SPACE WARPS sample shows that previous constraints on the average density profile of lens galaxies are robust. SPACE WARPS recovers about 65 per cent of known lenses, while the new candidates show a richer variety compared to those found by the two robots. This detection rate could be increased to 80 per cent by only using classifications performed by expert volunteers (albeit at the cost of a lower purity), indicating that the training and performance calibration of the citizen scientists is very important for the success of SPACE WARPS. In this work we present the SIMCT pipeline, used for generating in situ a sample of realistic simulated lensed images. This training sample, along with the false positives identified during the search, has a legacy value for testing future lens-finding algorithms. We make the pipeline and the training set publicly available.

Inferring Planet Occurrence Rates With a Q1-Q16 Kepler Planet Candidate Catalog Produced by a Machine Learning Classifier

NASA's Kepler Space Telescope monitored the photometric variations of over 170,000 stars within a ~100 square degree field in the constellation Cygnus, at half-hour cadence, over its four year prime mission. The Kepler SOC (Science Operations Center) pipeline calibrates the pixels of the target apertures for each star, corrects light curves for systematic error, and detects TCEs (threshold-crossing events) that may be due to transiting planets. Finally the pipeline estimates planet parameters for all TCEs and computes quantitative diagnostics that are used by the TCERT (Threshold Crossing Event Review Team) to produce a catalog containing KOIs (Kepler Objects of Interest). KOIs are TCEs that are determined to be either likely transiting planets or astrophysical false positives such as background eclipsing binary stars. Using examples from the Q1-Q16 TCERT KOI catalog as a training set, we created a machine-learning classifier that dispositions the TCEs into categories of PC (planet candidate), AFP (astrophysical false positive) and NTP (non-transiting phenomenon). The classifier uniformly and consistently applies heuristics developed by TCERT as well as other diagnostics to the Q1-Q16 TCEs to produce a more robust and reliable catalog of planet candidates than is possible with only human classification. In this work, we estimate planet occurrence rates, based on the machine-learning-produced catalog of Kepler planet candidates. Kepler was selected as the 10th mission of the Discovery Program.

A real-time coherent dedispersion pipeline for the giant metrewave radio telescope

NASA Astrophysics Data System (ADS)

De, Kishalay; Gupta, Yashwant

2016-02-01

A fully real-time coherent dedispersion system has been developed for the pulsar back-end at the Giant Metrewave Radio Telescope (GMRT). The dedispersion pipeline uses the single phased array voltage beam produced by the existing GMRT software back-end (GSB) to produce coherently dedispersed intensity output in real time, for the currently operational bandwidths of 16 MHz and 32 MHz. Provision has also been made to coherently dedisperse voltage beam data from observations recorded on disk. We discuss the design and implementation of the real-time coherent dedispersion system, describing the steps carried out to optimise the performance of the pipeline. Presently functioning on an Intel Xeon X5550 CPU equipped with a NVIDIA Tesla C2075 GPU, the pipeline allows dispersion free, high time resolution data to be obtained in real-time. We illustrate the significant improvements over the existing incoherent dedispersion system at the GMRT, and present some preliminary results obtained from studies of pulsars using this system, demonstrating its potential as a useful tool for low frequency pulsar observations. We describe the salient features of our implementation, comparing it with other recently developed real-time coherent dedispersion systems. This implementation of a real-time coherent dedispersion pipeline for a large, low frequency array instrument like the GMRT, will enable long-term observing programs using coherent dedispersion to be carried out routinely at the observatory. We also outline the possible improvements for such a pipeline, including prospects for the upgraded GMRT which will have bandwidths about ten times larger than at present.

Analytical solution and numerical study on water hammer in a pipeline closed with an elastically attached valve

NASA Astrophysics Data System (ADS)

Henclik, Sławomir

2018-03-01

The influence of dynamic fluid-structure interaction (FSI) onto the course of water hammer (WH) can be significant in non-rigid pipeline systems. The essence of this effect is the dynamic transfer of liquid energy to the pipeline structure and back, which is important for elastic structures and can be negligible for rigid ones. In the paper a special model of such behavior is analyzed. A straight pipeline with a steady flow, fixed to the floor with several rigid supports is assumed. The transient is generated by a quickly closed valve installed at the end of the pipeline. FSI effects are assumed to be present mainly at the valve which is fixed with a spring dash-pot attachment. Analysis of WH runs, especially transient pressure changes, for various stiffness and damping parameters of the spring dash-pot valve attachment is presented in the paper. The solutions are found analytically and numerically. Numerical results have been computed with the use of an own computer program developed on the basis of the four equation model of WH-FSI and the specific boundary conditions formulated at the valve. Analytical solutions have been found with the separation of variables method for slightly simplified assumptions. Damping at the dash-pot is taken into account within the numerical study. The influence of valve attachment parameters onto the WH courses was discovered and it was found the transient amplitudes can be reduced. Such a system, elastically attached shut-off valve in a pipeline or other, equivalent design can be a real solution applicable in practice.

The increasing interest in deepwater exploration and production has motivated the development of technologies required to accomplish tasks heretofore possible only onshore and in shallow water. The tremendous expense of technology development and the cost of specialized equipment has created concerns that the design life of these facilities may be compromised by corrosion. The requirements to develop and prove design parameters to meet these demands will require an ongoing environmental testing and materials evaluation and development program. This paper describes a two-fold corrosion testing program involving: (1) the installation of two corrosion test devices installed in-situ, and (2) a laboratorymore » test conducted in simulated site-specific seawater.

While the number of women entering U.S. medical schools has risen substantially in the past 25 years, the number of women in leadership positions in academic medicine is disproportionately small. The traditional pathway to academic leadership is through research. Women's health research is an ideal venue to fill the pipeline with talented women physicians and scientists who may become academic leaders in positions where they can promote positive change in women's health as well as mentor other women. The Office on Women's Health (OWH) in the U.S. Department of Health and Human Services has contracted with 18 academic medical centers to develop National Centers of Excellence in Women's Health. Emphasizing the integral link between women's health and women leaders, each of the Centers of Excellence must develop a leadership plan for women in academic medicine as part of the contract requirements. This paper describes the training programs in women's health research that have developed at five of the academic medical centers: the University of Wisconsin, Magee Women's Hospital, the University of Maryland, Medical College of Pennsylvania Hahnemann University, and the University of Illinois at Chicago. We discuss some of the challenges faced for both initiation and future viability of these programs as well as criteria by which these programs will be evaluated for success.

The EMBL-Hamburg Automated Crystal Structure Determination Platform is a system that combines a number of existing macromolecular crystallographic computer programs and several decision-makers into a software pipeline for automated and efficient crystal structure determination. The pipeline can be invoked as soon as X-ray data from derivatized protein crystals have been collected and processed. It is controlled by a web-based graphical user interface for data and parameter input, and for monitoring the progress of structure determination. A large number of possible structure-solution paths are encoded in the system and the optimal path is selected by the decision-makers as the structure solution evolves. The processes have been optimized for speed so that the pipeline can be used effectively for validating the X-ray experiment at a synchrotron beamline.

Structured, mentored research programs for high school and undergraduate students from underrepresented minority (URM) backgrounds are needed to increase the diversity of our nation’s biomedical research workforce. In particular, a robust pipeline of investigators from the communities disproportionately affected by the HIV epidemic is needed not only for fairness and equity but for insights and innovations to address persistent racial and ethnic disparities in new infections. We created the Summer HIV/AIDS Research Program (SHARP) at the San Francisco Department of Public Health for URM undergraduates as a 12-week program of hands-on research experience, one-on-one mentoring by a senior HIV investigator, didactic seminars for content and research methods, and networking opportunities. The first four cohorts (2012–2015) of SHARP gained research skills, built confidence in their abilities and self-identified as scientists. In addition, the majority of program alumni is employed in research positions and has been admitted to or is pursuing graduate degree programs in fields related to HIV prevention. While we await empirical studies of specific mentoring strategies at early educational stages, programs that engage faculty who are sensitive to the unique challenges facing diverse students and who draw lessons from established mentoring frameworks can help build an inclusive generation of HIV researchers.

Searching for pulsars using image pattern recognition

In the modern era of big data, many fields of astronomy are generating huge volumes of data, the analysis of which can sometimes be the limiting factor in research. Fortunately, computer scientists have developed powerful data-mining techniques that can be applied to various fields. In this paper, we present a novel artificial intelligence (AI) program that identifies pulsars from recent surveys by using image pattern recognition with deep neural nets—the PICS (Pulsar Image-based Classification System) AI. The AI mimics human experts and distinguishes pulsars from noise and interference by looking for patterns from candidate plots. Different from other pulsar selectionmore » programs that search for expected patterns, the PICS AI is taught the salient features of different pulsars from a set of human-labeled candidates through machine learning. The training candidates are collected from the Pulsar Arecibo L-band Feed Array (PALFA) survey. The information from each pulsar candidate is synthesized in four diagnostic plots, which consist of image data with up to thousands of pixels. The AI takes these data from each candidate as its input and uses thousands of such candidates to train its ∼9000 neurons. The deep neural networks in this AI system grant it superior ability to recognize various types of pulsars as well as their harmonic signals. The trained AI's performance has been validated with a large set of candidates from a different pulsar survey, the Green Bank North Celestial Cap survey. In this completely independent test, the PICS ranked 264 out of 277 pulsar-related candidates, including all 56 previously known pulsars and 208 of their harmonics, in the top 961 (1%) of 90,008 test candidates, missing only 13 harmonics. The first non-pulsar candidate appears at rank 187, following 45 pulsars and 141 harmonics. In other words, 100% of the pulsars were ranked in the top 1% of all candidates, while 80% were ranked higher than any noise or interference. The performance of this system can be improved over time as more training data are accumulated. This AI system has been integrated into the PALFA survey pipeline and has discovered six new pulsars to date.« less

In other words, 100% of the pulsars were ranked in the top 1% of all candidates, while 80% were ranked higher than any noise or interference. The performance of this system can be improved over time as more training data are accumulated. This AI system has been integrated into the PALFA survey pipeline and has discovered six new pulsars to date.

2010-01-01

Objectives To determine whether participation in the University of Illinois at Chicago College of Pharmacy (UIC-COP) Pathways to Pharmacy, an early urban pipeline program, motivated underrepresented minority students to pursue a prepharmacy curriculum in college and choose pharmacy as a career. Methods Over a 4-year period, underrepresented minority high school students participated in a comprehensive 6-week program that included 3 weeks of prepharmacy curriculum and intensive socialization and 3 weeks working as a pharmacy technician in a chain pharmacy. The High School Survey of Student Engagement (HSSSE) was administered 3 times to 120 program participants from 2005-2008, with 4 open-ended questions added to the pretest, 3 open-ended questions added to the test administered at the midpoint of the program, and 7 open-ended questions added to the posttest. Results After completing the program, 88 (75%) of the 120 students enrolled in the college's prepharmacy curriculum and planned to pursue a career in pharmacy, 10 (8%) were not interested in pursuing a career in pharmacy, and 20 (17%) were undecided, compared to the pretest data which showed that 40 (33%) were interested in a career in pharmacy, and 80 (67%) were undecided (p < 0.0001). Conclusions Participation in a Pathways to Pharmacy program grounded in both a theoretical and conceptual socialization model framework increased the number of underrepresented minority students in the pipeline to pharmacy schools.

TagDigger: user-friendly extraction of read counts from GBS and RAD-seq data.

PubMed

Clark, Lindsay V; Sacks, Erik J

2016-01-01

In genotyping-by-sequencing (GBS) and restriction site-associated DNA sequencing (RAD-seq), read depth is important for assessing the quality of genotype calls and estimating allele dosage in polyploids. However, existing pipelines for GBS and RAD-seq do not provide read counts in formats that are both accurate and easy to access. Additionally, although existing pipelines allow previously-mined SNPs to be genotyped on new samples, they do not allow the user to manually specify a subset of loci to examine. Pipelines that do not use a reference genome assign arbitrary names to SNPs, making meta-analysis across projects difficult. We created the software TagDigger, which includes three programs for analyzing GBS and RAD-seq data. The first script, tagdigger_interactive.py, rapidly extracts read counts and genotypes from FASTQ files using user-supplied sets of barcodes and tags. Input and output is in CSV format so that it can be opened by spreadsheet software. Tag sequences can also be imported from the Stacks, TASSEL-GBSv2, TASSEL-UNEAK, or pyRAD pipelines, and a separate file can be imported listing the names of markers to retain. A second script, tag_manager.py, consolidates marker names and sequences across multiple projects. A third script, barcode_splitter.py, assists with preparing FASTQ data for deposit in a public archive by splitting FASTQ files by barcode and generating MD5 checksums for the resulting files. TagDigger is open-source and freely available software written in Python 3. It uses a scalable, rapid search algorithm that can process over 100 million FASTQ reads per hour. TagDigger will run on a laptop with any operating system, does not consume hard drive space with intermediate files, and does not require programming skill to use.

Light curves for Transiting Exoplanet Survey Satellite (TESS) target stars will be extracted and searched for transiting planet signatures in the Science Processing Operations Center (SPOC) Science Pipeline at NASA Ames Research Center. Targets for which the transiting planet detection threshold is exceeded will be processed in the Data Validation (DV) component of the Pipeline. The primary functions of DV are to (1) characterize planets identified in the transiting planet search, (2) search for additional transiting planet signatures in light curves after modeled transit signatures have been removed, and (3) perform a comprehensive suite of diagnostic tests to aid in discrimination between true transiting planets and false positive detections. DV data products include extensive reports by target, one-page summaries by planet candidate, and tabulated transit model fit and diagnostic test results. DV products may be employed by humans and automated systems to vet planet candidates identified in the Pipeline. TESS will launch in 2018 and survey the full sky for transiting exoplanets over a period of two years. The SPOC pipeline was ported from the Kepler Science Operations Center (SOC) codebase and extended for TESS after the mission was selected for flight in the NASA Astrophysics Explorer program. We describe the Data Validation component of the SPOC Pipeline. The diagnostic tests exploit the flux (i.e., light curve) and pixel time series associated with each target to support the determination of the origin of each purported transiting planet signature. We also highlight the differences between the DV components for Kepler and TESS. Candidate planet detections and data products will be delivered to the Mikulski Archive for Space Telescopes (MAST); the MAST URL is archive.stsci.edu/tess. Funding for the TESS Mission has been provided by the NASA Science Mission Directorate.

2013-01-01

Radiological measurements are one of the key variables in widely adopted guidelines (WHO, RECIST) that standardize and objectivize response assessment in oncology care. Measurements are typically described in free-text, narrative radiology reports. We present a natural language processing pipeline that extracts measurements from radiology reports and pairs them with extracted measurements from prior reports of the same clinical finding, e.g., lymph node or mass. A ground truth was created by manually pairing measurements in the abdomen CT reports of 50 patients. A Random Forest classifier trained on 15 features achieved superior results in an end-to-end evaluation of the pipeline on the extraction and pairing task: precision 0.910, recall 0.878, F-measure 0.894, AUC 0.988. Representing the narrative content in terms of UMLS concepts did not improve results. Applications of the proposed technology include data mining, advanced search and workflow support for healthcare professionals managing radiological measurements.

A Web-Based Framework For a Time-Domain Warehouse

NASA Astrophysics Data System (ADS)

Brewer, J. M.; Bloom, J. S.; Kennedy, R.; Starr, D. L.

2009-09-01

The Berkeley Transients Classification Pipeline (TCP) uses a machine-learning classifier to automatically categorize transients from large data torrents and provide automated notification of astronomical events of scientific interest. As part of the training process, we created a large warehouse of light-curve sources with well-labelled classes that serve as priors to the classification engine. This web-based interactive framework, which we are now making public via DotAstro.org (http://dotastro.org/), allows us to ingest time-variable source data in a wide variety of formats and store it in a common internal data model. Data is passed between pipeline modules in a prototype XML representation of time-series format (VOTimeseries), which can also be emitted to collaborators through dotastro.org. After import, the sources can be visualized using Google Sky, light curves can be inspected interactively, and classifications can be manually adjusted.

Application of the actor model to large scale NDE data analysis

NASA Astrophysics Data System (ADS)

Coughlin, Chris

2018-03-01

The Actor model of concurrent computation discretizes a problem into a series of independent units or actors that interact only through the exchange of messages. Without direct coupling between individual components, an Actor-based system is inherently concurrent and fault-tolerant. These traits lend themselves to so-called "Big Data" applications in which the volume of data to analyze requires a distributed multi-system design. For a practical demonstration of the Actor computational model, a system was developed to assist with the automated analysis of Nondestructive Evaluation (NDE) datasets using the open source Myriad Data Reduction Framework. A machine learning model trained to detect damage in two-dimensional slices of C-Scan data was deployed in a streaming data processing pipeline. To demonstrate the flexibility of the Actor model, the pipeline was deployed on a local system and re-deployed as a distributed system without recompiling, reconfiguring, or restarting the running application.

Natural gas pipeline leaks across Washington, DC.

Pipeline safety in the United States has increased in recent decades, but incidents involving natural gas pipelines still cause an average of 17 fatalities and $133 M in property damage annually. Natural gas leaks are also the largest anthropogenic source of the greenhouse gas methane (CH4) in the U.S. To reduce pipeline leakage and increase consumer safety, we deployed a Picarro G2301 Cavity Ring-Down Spectrometer in a car, mapping 5893 natural gas leaks (2.5 to 88.6 ppm CH4) across 1500 road miles of Washington, DC. The δ(13)C-isotopic signatures of the methane (-38.2‰ ± 3.9‰ s.d.) and ethane (-36.5 ± 1.1 s.d.) and the CH4:C2H6 ratios (25.5 ± 8.9 s.d.) closely matched the pipeline gas (-39.0‰ and -36.2‰ for methane and ethane; 19.0 for CH4/C2H6). Emissions from four street leaks ranged from 9200 to 38,200 L CH4 day(-1) each, comparable to natural gas used by 1.7 to 7.0 homes, respectively. At 19 tested locations, 12 potentially explosive (Grade 1) methane concentrations of 50,000 to 500,000 ppm were detected in manholes. Financial incentives and targeted programs among companies, public utility commissions, and scientists to reduce leaks and replace old cast-iron pipes will improve consumer safety and air quality, save money, and lower greenhouse gas emissions.

There is mounting concern that clinician-scientists are a vanishing species and that the pipeline for clinical and translational research (CTR) investigators is in jeopardy. For the majority of current junior CTR investigators, the career path involves first obtaining a National Institutes of Health (NIH)-funded K-type career development award, particularly K08 and K23, and subsequently an NIH R01. This transition, popularly referred to as K2R, is a major hurdle with a low success rate and gaps in funding. In this Perspective, the authors identify factors that facilitate K2R transition and important aspects of increasing and sustaining the pipeline of CTR investigators. They also highlight significant differences in success rates of women and those underrepresented in biomedical research. Early career exposure to research methodology, protected time, multidisciplinary mentoring, and institutional "culture shift" are important for fostering and rewarding team science. Mentoring is the single most important contributor to K2R success, and emerging evidence suggests that formal mentor training and team mentoring are effective. Leadership training can empower junior investigators to thrive as independent CTR investigators. Future research should focus on delineating the difference between essential and supplemental factors to achieve this transition, and mentoring methods that foster success, including those that promote K2R transition of women and those underrepresented in biomedical research. The Clinical and Translational Science Awards National Consortium is well positioned to test existing models aimed at shortening the time frame, increasing the rate of K2R transition, and identifying strategies that improve success.

Landscape scale ecological monitoring as part of an EIA of major construction activities: experience at the Turkish section of the BTC crude oil pipeline project.

PubMed

Sahin, Sükran; Kurum, Ekrem

2009-09-01

Ecological monitoring is a complementary component of the overall environmental management and monitoring program of any Environmental Impact Assessment (EIA) report. The monitoring method should be developed for each project phase and allow for periodic reporting and assessment of compliance with the environmental conditions and requirements of the EIA. Also, this method should incorporate a variance request program since site-specific conditions can affect construction on a daily basis and require time-critical application of alternative construction scenarios or environmental management methods integrated with alternative mitigation measures. Finally, taking full advantage of the latest information and communication technologies can enhance the quality of, and public involvement in, the environmental management program. In this paper, a landscape-scale ecological monitoring method for major construction projects is described using, as a basis, 20 months of experience on the Baku-Tbilisi-Ceyhan (BTC) Crude Oil Pipeline Project, covering Turkish Sections Lot B and Lot C. This analysis presents suggestions for improving ecological monitoring for major construction activities.

Building an academic-community partnership for increasing representation of minorities in the health professions.

2004-11-01

We evaluated collaboration among academic and community partners in a program to recruit African American youth into the health professions. Six institutions of higher education, an urban school system, two community organizations, and two private enterprises became partners to create a health career pipeline for this population. The pipeline consisted of 14 subprograms designed to enrich academic science curricula, stimulate the interest of students in health careers, and facilitate entry into professional schools and other graduate-level educational programs. Subprogram directors completed questionnaires regarding a sense of common mission/vision and coordination/collaboration three times during the 3-year project. The partners strongly shared a common mission and vision throughout the duration of the program, although there was some weakening in the last phase. Subprogram directors initially viewed coordination/collaboration as weak, but by midway through the project period viewed it as stronger. Feared loss of autonomy was foremost among several factors that threatened collaboration among the partners. Collaboration was improved largely through a process of building trust among the partners.

Through establishing control parameters from blade outside to inside, the parametric design of air-cooled turbine blade based on airfoil has been implemented. On the basis of fast updating structure features and generating solid model, a complex cooling system has been created. Different flow units are modeled into a complex network topology with parallel and serial connection. Applying one-dimensional flow theory, programs have been composed to get pipeline network physical quantities along flow path, including flow rate, pressure, temperature and other parameters. These inner units parameters set as inner boundary conditions for external flow field calculation program HIT-3D by interpolation, thus to achieve full field thermal coupling simulation. Referring the studies in literatures to verify the effectiveness of pipeline network program and coupling algorithm. After that, on the basis of a modified design, and with the help of iSIGHT-FD, an optimization platform had been established. Through MIGA mechanism, the target of enhancing cooling efficiency has been reached, and the thermal stress has been effectively reduced. Research work in this paper has significance for rapid deploying the cooling structure design.

MERTELEMPROC processes telemetered data in data product format and generates Experiment Data Records (EDRs) for many instruments (HAZCAM, NAVCAM, PANCAM, microscopic imager, Moessbauer spectrometer, APXS, RAT, and EDLCAM) on the Mars Exploration Rover (MER). If the data is compressed, then MERTELEMPROC decompresses the data with an appropriate decompression algorithm. There are two compression algorithms (ICER and LOCO) used in MER. This program fulfills a MER specific need to generate Level 1 products within a 60-second time requirement. EDRs generated by this program are used by merinverter, marscahv, marsrad, and marsjplstereo to generate higher-level products for the mission operations. MERTELEPROC was the first GDS program to process the data product. Metadata of the data product is in XML format. The software allows user-configurable input parameters, per-product processing (not streambased processing), and fail-over is allowed if the leading image header is corrupted. It is used within the MER automated pipeline. MERTELEMPROC is part of the OPGS (Operational Product Generation Subsystem) automated pipeline, which analyzes images returned by in situ spacecraft and creates level 1 products to assist in operations, science, and outreach.

As a professor who relies on graduate students to participate in my research program, I work to ensure that the pipeline of graduate students is full. This presentation will discuss a variety of strategies that I have used to advertise the opportunities of graduate school, many of which use existing infrastructure at the University of Pennsylvania. These strategies involve a combination of public speaking, discussion groups, and faculty advising. During these exchanges it's important to both contrast the career opportunities for B.S., M.S. and Ph.D. degree holders and outline the financial facts about graduate school. These modest efforts have increased the number of Penn undergraduates pursuing doctorate degrees.

Bioinformatics experiments are typically composed of programs in pipelines manipulating an enormous quantity of data. An interesting approach for managing those experiments is through workflow management systems (WfMS). In this work we discuss WfMS features to support genome homology workflows and present some relevant issues for typical genomic experiments. Our evaluation used Kepler WfMS to manage a real genomic pipeline, named OrthoSearch, originally defined as a Perl script. We show a case study detecting distant homologies on trypanomatids metabolic pathways. Our results reinforce the benefits of WfMS over script languages and point out challenges to WfMS in distributed environments.

The current practice is to apply a semi-physical models such as the Hapke models (e.g., Icarus 195, 2008). These are expressed in a closed form so that they are fast to apply. The problem is that the validity of the model is not guaranteed, and the derived properties related to particle scattering can be unrealistic (JQSRT 113, 2012).Our pipeline consists of individual scattering simulation codes and a main program that chains them together. The chain for analyzing a macroscopic target with space-weathered mineral would go as: (1) Scattering properties of small inclusions inside a host matrix are derived using exact Maxwell equation solvers. From the scattering properties, we use the so-called incoherent fields and Mueller matrices as input for the next step; (2) Scattering by a regolith grain is solved using a geometrical optics method with surface reflections, internal absorption, and internal diffuse scattering; (3) The radiative transfer simulation is executed inputting the regolith grains from the previous step as the scatterers in a macroscopic planar volume element.For the most realistic asteroid reflectance model, the chain would produce the properties of a planar surface element. Then, a shadowing simulation over the surface elements would be considered, and finally the asteroid phase function would be solved by integrating the bidirectional reflectance distribution function of the planar element over the object's realistic shape model.The tools in the proposed chain already exist, and practical task for us is to tie these together into an easy-to-use public pipeline. We plan to open the pipeline as a web-based open service a dedicated server, using Django application server and Python environment for the main functionality. The individual programs to be ran under the chain can still be programmed with Fortran, C, or other.We acknowledge the ERC AdG No. 320773 ‘SAEMPL’ and the computational resources provided by CSC — IT Center for Science Ltd., Finland.

Issues in electric power in India: Challenges and opportunities

NASA Astrophysics Data System (ADS)

Tongia, Rahul

This dissertation provides an examination of three facets of the Indian power program. The first issue we analyze is the current regulatory environment and guidelines in place for independent power producers and other generators, focusing on possible tradeoffs between prices and investor returns. The analysis shows that investor rates of return are significantly higher than the nominal 16% as stipulated by the Central Electricity Authority guidelines, and an uncertainty analysis reveals the relative importance of various input and project parameters. We discuss problems with the existing guidelines, and provide options for changes in policy. Adoption of modified guidelines that are more transparent and do not focus on project capital structures are likely to result in more affordable tariffs, less delays in project completion and yet provide adequate rates of return for investors. India's nuclear power program is based on indigenous materials and technology, with the potential for providing energy security for many decades. We examine the technical validity of this plan, especially the role of fast breeder reactors for extending the domestic uranium supplies. The analysis shows that breeding is unlikely to occur at anywhere near the rates envisioned, leading to a slow growth of fast breeder reactors. In addition, domestic uranium reserves restrict growth of Pressurized Heavy Water Reactors, which are likely to be the main contributors to nuclear capacity in the short term. To increase the share of nuclear power in the coming decades, India should consider the construction of a number of large thermal reactors based on indigenous and imported uranium. We also present policy options for such changes to India's nuclear power program. This dissertation examines in detail the policy, technology, and economics of an overland pipeline supplying natural gas to India and Pakistan. Such a pipeline would be shared by both countries, and would be a strong confidence building measure, offering a unique opportunity for cooperation. As natural gas pipelines exhibit significant economies of scale, a shared pipeline would also offer the lowest price natural gas for both countries. This study addresses some of the potential concerns, suggesting options for overcoming security of supply worries. (Abstract shortened by UMI.)

...EPA is amending the requirements under EPA's diesel sulfur program related to the sulfur content of locomotive and marine (LM) diesel fuel produced by transmix processors and pipeline facilities. These amendments will reinstate the ability of locomotive and marine diesel fuel produced from transmix by transmix processors and pipeline operators to meet a maximum 500 parts per million (ppm) sulfur standard outside of the Northeast Mid-Atlantic Area and Alaska and expand this ability to within the Northeast Mid-Atlantic Area provided that: the fuel is used in older technology locomotive and marine engines that do not require 15 ppm sulfur diesel fuel, and the fuel is kept segregated from other fuel. These amendments will provide significant regulatory relief for transmix processors and pipeline operators to allow the petroleum distribution system to function efficiently while continuing to transition the market to virtually all ultra-low sulfur diesel fuel (ULSD, i.e. 15 ppm sulfur diesel fuel) and the environmental benefits it provides.

Understanding how neural information is processed in physiological and pathological states would benefit from precise detection, localization, and quantification of the activity of all neurons across the entire brain, which has not, to date, been achieved in the mammalian brain. We introduce a pipeline for high-speed acquisition of brain activity at cellular resolution through profiling immediate early gene expression using immunostaining and light-sheet fluorescence imaging, followed by automated mapping and analysis of activity by an open-source software program we term ClearMap. We validate the pipeline first by analysis of brain regions activated in response to haloperidol. Next, we report new cortical regions downstream of whisker-evoked sensory processing during active exploration. Last, we combine activity mapping with axon tracing to uncover new brain regions differentially activated during parenting behavior. This pipeline is widely applicable to different experimental paradigms, including animal species for which transgenic activity reporters are not readily available. Copyright © 2016 Elsevier Inc.

CamBAfx is a workflow application designed for both researchers who use workflows to process data (consumers) and those who design them (designers). It provides a front-end (user interface) optimized for data processing designed in a way familiar to consumers. The back-end uses a pipeline model to represent workflows since this is a common and useful metaphor used by designers and is easy to manipulate compared to other representations like programming scripts. As an Eclipse Rich Client Platform application, CamBAfx's pipelines and functions can be bundled with the software or downloaded post-installation. The user interface contains all the workflow facilities expected by consumers. Using the Eclipse Extension Mechanism designers are encouraged to customize CamBAfx for their own pipelines. CamBAfx wraps a workflow facility around neuroinformatics software without modification. CamBAfx's design, licensing and Eclipse Branding Mechanism allow it to be used as the user interface for other software, facilitating exchange of innovative computational tools between originating labs.

The Clinician as Leader: Why, How, and When.

Stoller, James K

Clinicians are inveterate leaders. We lead patients through the difficult maze of illness, families through the travails of ill loved ones, and physicians-in-training through the gauntlet of learning medicine. Yet, in the context of a range of leadership styles that effective leaders must be able to deploy situationally, physician leaders have traditionally defaulted to a "command and control" style that fosters the concept of physicians as "Viking warriors" or "heroic lone healers." The perverse effects of "command and control" are that this style conspires against collaboration and tends to be perpetuated as aspiring leaders emulate their predecessors. Because healthcare faces challenges of cost, access, and quality and is in the throes of change, the current landscape requires effective leadership. Though still relatively uncommon among healthcare organizations, frontrunner organizations are offering leadership development programs. The design of such programs requires clarity about requisite leadership competencies and about how and when to best to deliver such curricula. As one example, the American Thoracic Society has launched its Emerging Leaders Program (ELP), which is currently offering a leadership development curriculum to 18 selected emerging leaders. The ATS ELP curriculum focuses on awareness of self and system and incorporates highly participatory sessions on emotional intelligence, teambuilding, change management, situational leadership, appreciative inquiry, process and quality improvement, strategic planning, and organizational culture. Short-term deliverables are the development and presentation of business plans for innovations proposed by the group. Hoped for longer-term outcomes include an enhanced leadership pipeline for global respiratory health.

National assessment of capacity in public health, environmental, and agricultural laboratories--United States, 2011.

PubMed

2013-03-08

In 2011, the University of Michigan's Center of Excellence in Public Health Workforce Studies and the Association of Public Health Laboratories (APHL) assessed the workforce and program capacity in U.S. public health, environmental, and agricultural laboratories. During April-August 2011, APHL sent a web-based questionnaire to 105 public health, environmental, and agricultural laboratory directors comprising all 50 state public health laboratories, 41 local public health laboratories, eight environmental laboratories, and six agricultural laboratories. This report summarizes the results of the assessment, which inquired about laboratory capacity, including total number of laboratorians by occupational classification and self-assessed ability to carry out functions in 19 different laboratory program areas. The majority of laboratorians (74%) possessed a bachelor's degree, associate's degree, or a high school education or equivalency; 59% of all laboratorians were classified as laboratory scientists. The greatest percentage of laboratories reported no, minimal, or partial program capacity in toxicology (45%), agricultural microbiology (54%), agricultural chemistry (50%), and education and training for their employees (51%). Nearly 50% of laboratories anticipated that more than 15% of their workforce would retire, resign, or be released within 5 years, lower than the anticipated retirement eligibility rate of 27% projected for state public health workers. However, APHL and partners in local, state, and federal public health should collaborate to address gaps in laboratory capacity and rebuild the workforce pipeline to ensure an adequate future supply of public health laboratorians.
