    Human performance in orbit is currently limited by several factors beyond the intrinsic awkwardness of motor control in weightlessness. Cognitive functioning can be affected by such factors as cumulative sleep loss, stress and the psychological effects of long-duration small-group isolation. When an astronaut operates a scientific experiment, the performance decrement associated with such factors can lead to lost or poor quality data and even the total loss of a scientific objective, at great cost to the sponsors and to the dismay of the Principal Investigator. In long-duration flights, as anticipated on the International Space Station and on any planetary exploration, the experimental model is further complicated by long delays between training and experiment, and the large number of experiments each crew member must perform. Although no documented studies have been published on the subject, astronauts report that an unusually large number of simple errors are made in space. Whether a result of the effects of microgravity, accumulated fatigue, stress or other factors, this pattern of increased error supports the need for a computerized decision-making aid for astronauts performing experiments. Artificial intelligence and expert systems might serve as powerful tools for assisting experiments in space. Those conducting space experiments typically need assistance exactly when the planned checklist does not apply. Expert systems, which use bits of human knowledge and human methods to respond appropriately to unusual situations, have a flexibility that is highly desirable in circumstances where an invariably predictable course of action/response does not exist. Frequently the human expert on the ground is unavailable, lacking the latest information, or not consulted by the astronaut conducting the experiment. In response to these issues, we have developed "Principal Investigator-in-a-Box," or [PI], to capture the reasoning process of the real expert, the Principal

    1996-10-01

    This remedial investigation (RI)/feasibility study (FS) supports the selection of remedial actions for the David Witherspoon, Inc. 901 Maryville Pike Site in Knoxville, Tennessee. Operations at the site, used as a recycling center, have resulted in past, present, and potential future releases of hazardous substances in to the environment. This Site is a Tennessee Superfund site. A phased approach was planned to (1) gather existing data from previous investigations managed by the Tenn. Dept. of Environment and Conservation; (2) perform a preliminary RI, including risk assessments, and an FS with existing data to identify areas where remedial action may be necessary; (3) gather additional field data to adequately define the nature and extent of risk-based contaminants that present identifiable threats to human and/or ecological receptors; and (4) develop remedial action alternatives to reduce risks to acceptable levels.

  11. Investigation of the Velocity Field and Flow Regime of David Glacier and Drygalski Ice Tongue, Antarctica

    NASA Astrophysics Data System (ADS)

    Wuite, J.; Jezek, K. C.

    2005-12-01

    Recent observations of outlet glaciers in both Greenland and Antarctica show surprising and unexpectedly rapid changes in flow velocities. Outlet glaciers drain the majority of the polar ice sheets and consequently these changes threaten their stability and can lead to rising sea levels. It is therefore important to investigate their flow governing processes and document changes. We measured surface velocity over large portions of David Glacier and its floating seaward extension Drygalski Ice Tongue. This is the largest outlet glacier on the Scott Coast draining a section of the East Antarctic Ice Sheet into the Ross Sea. Giant iceberg B15-A recently collided with the ice tongue and broke off a significant section. To obtain velocities we used combinations of intensity feature tracking, interferometric speckle tracking and phase interferometry using RADARSAT-1 images acquired during the AMM-1 and MAMM missions. We compare short term velocities, 3-year averaged velocities and earlier studies to analyze spatial and temporal variability of the surface velocity field. We use obtained velocities, in combination with isostatically derived ice thickness from ICESat data, to estimate basal melting along the glacier. Also we investigate the role of lateral drag through force-budget theory and determine the equilibrium profile of the ice tongue. Unlike for example the West Antarctic Ice Streams and Jakobshavn Isbrae, our data suggests that the David Glacier velocity field has remained relatively constant from about 1991 - 2000 and likely much longer. The pattern of melting and freezing along the base of the glacier is consistent with an ice pump mechanism. In the fjord lateral drag opposes approximately 90% of the driving stress; this gradually drops to the point where most resistance comes from longitudinal stress gradients. We find the modeled and ICESat derived profile agree favorably suggesting steady state conditions

  13. Principal Investigator Microgravity Services: USMP-3

    NASA Technical Reports Server (NTRS)

    Rogers, Melissa J. B.; Hrovat, Kenneth; Moskowitz, Milton E.; Reckart, Timothy; McPherson, Kevin M.; DeLombard, Richard

    1998-01-01

    Two accelerometers provided acceleration data during the STS-75 mission in support of the third United States Microgravity Payload (USMP-3) experiments. The Orbital Acceleration Research Experiment (OARE) and the Space Acceleration Measurement System (SAMS) provided a measure of the microgravity environment of the Space Shuttle Columbia. The OARE provided investigators with quasi-steady acceleration measurements after about a six hour time lag dictated by downlink constraints. SAMS data were downlinked in near-real-time and recorded on-board for post-mission analysis. These two accelerometer systems are briefly described. Using a combination of data analysis techniques, the microgravity environment related to several different Orbiter, crew, and experiment operations is presented and interpreted. The microgravity environment represented by SAMS and OARE data is comparable to the environments measured by these instruments on earlier microgravity science missions. Thruster activity on this mission seen in the SAMS data appear to be more frequent than on other microgravity missions with the combined firings of the F5L and F5R jets producing significant acceleration transients. Of the events studied, the crew activities performed in the middeck and flight deck, SPREE table rotations, a waste collection system compaction, and a fuel cell purge had negligible effects on the microgravity environment of the USMP-3 carriers. The Ku band antenna repositioning activity resulted in a brief interruption of the ubiquitous 17 Hz signal in the SAMS data. In addition, the auxiliary power unit operations during the Flight Control System checkout appeared to have a significant impact on the microgravity environment.

  17. Principal Investigator Microgravity Services Role in ISS Acceleration Data Distribution

    NASA Technical Reports Server (NTRS)

    McPherson, Kevin

    1999-01-01

    Measurement of the microgravity acceleration environment on the International Space Station will be accomplished by two accelerometer systems. The Microgravity Acceleration Measurement System will record the quasi-steady microgravity environment, including the influences of aerodynamic drag, vehicle rotation, and venting effects. Measurement of the vibratory/transient regime comprised of vehicle, crew, and equipment disturbances will be accomplished by the Space Acceleration Measurement System-II. Due to the dynamic nature of the microgravity environment and its potential to influence sensitive experiments, Principal Investigators require distribution of microgravity acceleration in a timely and straightforward fashion. In addition to this timely distribution of the data, long term access to International Space Station microgravity environment acceleration data is required. The NASA Glenn Research Center's Principal Investigator Microgravity Services project will provide the means for real-time and post experiment distribution of microgravity acceleration data to microgravity science Principal Investigators. Real-time distribution of microgravity environment acceleration data will be accomplished via the World Wide Web. Data packets from the Microgravity Acceleration Measurement System and the Space Acceleration Measurement System-II will be routed from onboard the International Space Station to the NASA Glenn Research Center's Telescience Support Center. Principal Investigator Microgravity Services' ground support equipment located at the Telescience Support Center will be capable of generating a standard suite of acceleration data displays, including various time domain and frequency domain options. These data displays will be updated in real-time and will periodically update images available via the Principal Investigator Microgravity Services web page.

    This article discusses misconceptions in Bennell, Jones, Taylor, and Snook's (2006) critique of Kocsis (2003a) concerning the validities and abilities surrounding criminal profiling. It also, in part, serves to canvass the approach of investigative psychology and what may be viewed as an imperative for some of its proponents to challenge evidence into the validity of criminal profiling, which is not easily reconcilable with that ideology.

    The European Zebrafish Principal Investigator Meeting (EZPM) is an ideal forum for group leaders using this fantastic animal model not only to discuss science but also to strengthen their interactions, to push forward technological advances, and to define guidelines for the use of this fish in research. The city of Lisbon (Portugal) was voted by the European group leaders to be the setting for the 4th EZPM, and the organizing committee, composed by Leonor Saúde (iMM Lisboa, PT), Susana Lopes (CEDOC, PT), Michael Orger (Champalimaud Foundation, PT), Rui Oliveira (ISPA, PT), and António Jacinto (CEDOC, PT), was very enthusiastic to organize a productive event. The 4th EZPM took place from March 15 to 19 at Pavilhão do Conhecimento, a Science Museum and Educational Center winner of The Great Prize FAD of Arquitecture 1999 and The Society for Environmental Graphic Design Award 2011. Over 5 days, 135 group leaders (89 men and 46 women) coming from 19 different European countries and also from the United States, Turkey, Israel, Chile, and Singapore presented and discussed their recent research achievements. In addition to the scientific oral and poster presentations, the group leaders gathered in very lively community sessions on morphants versus mutants (chaired by Didier Stainier, Max Planck Institute for Heart and Lung Research, DE), funding issues (chaired by Uwe Strahle, KIT-ITG, DE), and gender equality (chaired by Corinne Houart, KCL, United Kingdom). One of the highlights of the 4th EZPM was the guided visit to Oceanário de Lisboa, an international award-winning place that celebrates life with a stunning display of living aquatic creatures.

  7. Equal team partners? The roles of principal investigators, co-principal investigators and co-investigators on federally supported research grants.

    PubMed

    Cohen, F L; Holm, K; Cloninger, L

    1995-01-01

    A survey of 188 NLN-accredited graduate nursing programs was done to determine how the research roles of principal investigator (PI), co-principal investigator (Co-PI) and co-investigator (Co-I) are supported and to examine the similarities and differences in benefits for PIs, Co-PIs and Co-Is. Most schools did not provide salary supplementation in addition to the usual salary for any investigators. For other benefits, the PI was more likely than was the Co-PI or Co-I to receive direct access to indirect cost recovery dollars, the use of extra research assistants, and the reduction of teaching time commensurate with the time supported by their grant. If the team approach is truly valued, should not all investigators be rewarded in a like manner?

     To examine the association between the presence of individual principal investigators' financial ties to the manufacturer of the study drug and the trial's outcomes after accounting for source of research funding.  Cross sectional study of randomized controlled trials (RCTs).  Studies published in "core clinical" journals, as identified by Medline, between 1 January 2013 and 31 December 2013.  Random sample of RCTs focused on drug efficacy.  Association between financial ties of principal investigators and study outcome.  A total of 190 papers describing 195 studies met inclusion criteria. Financial ties between principal investigators and the pharmaceutical industry were present in 132 (67.7%) studies. Of 397 principal investigators, 231 (58%) had financial ties and 166 (42%) did not. Of all principal investigators, 156 (39%) reported advisor/consultancy payments, 81 (20%) reported speakers' fees, 81 (20%) reported unspecified financial ties, 52 (13%) reported honorariums, 52 (13%) reported employee relationships, 52 (13%) reported travel fees, 41 (10%) reported stock ownership, and 20 (5%) reported having a patent related to the study drug. The prevalence of financial ties of principal investigators was 76% (103/136) among positive studies and 49% (29/59) among negative studies. In unadjusted analyses, the presence of a financial tie was associated with a positive study outcome (odds ratio 3.23, 95% confidence interval 1.7 to 6.1). In the primary multivariate analysis, a financial tie was significantly associated with positive RCT outcome after adjustment for the study funding source (odds ratio 3.57 (1.7 to 7.7). The secondary analysis controlled for additional RCT characteristics such as study phase, sample size, country of first authors, specialty, trial registration, study design, type of analysis, comparator, and outcome measure. These characteristics did not appreciably affect the relation between financial ties and study outcomes (odds ratio 3.37, 1

  12. Damage localization in linear-form structures based on sensitivity investigation for principal component analysis

    NASA Astrophysics Data System (ADS)

    Viet Ha, Nguyen; Golinval, Jean-Claude

    2010-10-01

    This paper addresses the problem of damage detection and localization in linear-form structures. Principal component analysis (PCA) is a popular technique for dynamic system investigation. The aim of the paper is to present a damage diagnosis method based on sensitivities of PCA results in the frequency domain. Starting from frequency response functions (FRFs) measured at different locations on the structure; PCA is performed to determine the main features of the signals. Sensitivities of principal directions obtained from PCA to structural parameters are then computed and inspected according to the location of sensors; their variation from the healthy state to the damaged state indicates damage locations. It is worth noting that damage localization is performed without the need of modal identification. Influences of some features as noise, choice of parameter and number of sensors are discussed. The efficiency and limitations of the proposed method are illustrated using numerical and real-world examples.

  13. Memories of David Kirzhnits

    2013-06-01

    In the mid-1950s, a new staff member appeared at the Theory Division of the Physical Institute of the Academy of Sciences (FIAN): David Abramovich Kirzhnits. A Moscow State University alumnus, after graduation he had been assigned to a large defense plant in the city of Gorky, where he had worked for several years as an engineer. He was "liberated" from there by Igor Evgenyevich Tamm, our department head, who managed to transfer him to FIAN. Igor Evgenyevich knew D. A. Kirzhnits - they had met in Moscow before Kirzhnits finished university. At that time Kirzhnits was performing thesis work with professor A. S. Kompaneyets as academic adviser. At his adviser's suggestion, D. Kirzhnits consulted with I. E. Tamm on questions pertaining to the thesis topic. I. E. Tamm took a great liking for the diploma student, and he even wanted to recruit D. A. Kirzhnits for the Theory Division immediately after graduation. But at that time (1949) this proved impossible for several reasons. First, D. Kirzhnits was, as they say, an "invalid of the fifth group" - a Jew - which during those years of violent struggle against cosmopolitanismb often proved an obstacle in looking for work. Second, during the years of mass repressions D. Kirzhnits' father had been arrested on treason charges (according to the charges, he had wanted to sell the Far East to Japan). After intensive investigation his father was released, but he lived only a little longer. Reports of this also could have impeded his acceptance. Third, Igor Evgenyevich didn't have enough weight in officials' eyes at that time and so was unable to overcome "first" and "second."...

  4. New software for computer-assisted dental-data matching in Disaster Victim Identification and long-term missing persons investigations: "DAVID Web".

    PubMed

    Clement, J G; Winship, V; Ceddia, J; Al-Amad, S; Morales, A; Hill, A J

    2006-05-15

    In 1997 an internally supported but unfunded pilot project at the Victorian Institute of Forensic Medicine (VIFM) Australia led to the development of a computer system which closely mimicked Interpol paperwork for the storage, later retrieval and tentative matching of the many AM and PM dental records that are often needed for rapid Disaster Victim Identification. The program was called "DAVID" (Disaster And Victim IDentification). It combined the skills of the VIFM Information Technology systems manager (VW), an experienced odontologist (JGC) and an expert database designer (JC); all current authors on this paper. Students did much of the writing of software to prescription from Monash University. The student group involved won an Australian Information Industry Award in recognition of the contribution the new software could have made to the DVI process. Unfortunately, the potential of the software was never realized because paradoxically the federal nature of Australia frequently thwarts uniformity of systems across the entire country. As a consequence, the final development of DAVID never took place. Given the recent problems encountered post-tsunami by the odontologists who were obliged to use the Plass Data system (Plass Data Software, Holbaek, Denmark) and with the impending risks imposed upon Victoria by the decision to host the Commonwealth Games in Melbourne during March 2006, funding was sought and obtained from the state government to update counter disaster preparedness at the VIFM. Some of these funds have been made available to upgrade and complete the DAVID project. In the wake of discussions between leading expert odontologists from around the world held in Geneva during July 2003 at the invitation of the International Committee of the Red Cross significant alterations to the initial design parameters of DAVID were proposed. This was part of broader discussions directed towards developing instruments which could be used by the ICRC's "The Missing

  8. Lessons from implementation of ecohealth projects in Southern Africa: A principal investigator's perspective.

    PubMed

    Chimbari, Moses John

    2017-11-01

    Ecohealth projects are designed to garner ownership among all stakeholders, such as researchers, communities, local leadership and policy makers. Ideally, designs should ensure that implementation goes smoothly and that findings from studies benefit the stakeholders, particularly bringing changes to the communities researched. Paradoxically, the process is fraught with challenges associated with implementation. Notwithstanding these challenges, evidence from projects implemented in southern Africa justify the need to invest in the subject of ecohealth. This paper describes and discusses a principal investigator's experience of leading ecohealth projects in Zimbabwe between 2002 and 2005, in Botswana between 2010 and 2014 and in South Africa (ongoing). The discourse is centred on issues of project management and leadership, transdisciplinarity, students' involvement, data management, community engagement, dissemination of research findings and the role of institutions in project management and implementation. The paper concludes that the ecohealth approach is valuable and should be encouraged making the following recommendations; 1) principal investigators must have a good understanding of socio-ecological systems, have excellent project management and writing skills, 2) more than one PI should be involved in the day-to-day running of the project in order to avoid disruption of project activities in the event that the PI leaves the project before it ends, 3) researchers should be trained in ecohealth principles and methodologies at the time of building the research teams, 4) full proposals should be developed with active participation of communities and stakeholders in order to develop a shared vision, 5) involvement of postdoctoral fellows and dedicated researchers with postgraduate students should be encouraged to avoid situations where some objectives are not fully addressed because of the narrow nature of students' work; and 6) citizen science should be

  9. David Hartley's Newtonian neuropsychology.

    PubMed

    Smith, C U

    1987-04-01

    David Hartley's association psychology has been immensely influential. His vibrationist neurophysiology has, in contrast, been largely overlooked and forgotten. Hartley's vibration theory is examined. On the one hand it is shown how closely it is related to Sir Isaac Newton's mathematical physics and on the other how well it complements the association theory. The vibration theory, indeed, strongly influenced Hartley's associationist psychology and hence is of more than merely antiquarian interest. Although Hartley's understanding of the central nervous system has long been superseded, his general ideas prefigure some aspects of contemporary neurophysiology and philosophy of mind and thus provide a further reason for rescuing his vibrationism from oblivion.

  10. Protecting Ideas: Ethical and Legal Considerations When a Grant's Principal Investigator Changes.

    PubMed

    Koniaris, Leonidas G; Coombs, Mary I; Meslin, Eric M; Zimmers, Teresa A

    2016-08-01

    Ethical issues related the responsible conduct of research involve questions concerning the rights and obligations of investigators to propose, design, implement, and publish research. When a principal investigator (PI) transfers institutions during a grant cycle, financial and recognition issues need to be addressed to preserve all parties' obligations and best interests in a mutually beneficial way. Although grants often transfer with the PI, sometimes they do not. Maintaining a grant at an institution after the PI leaves does not negate the grantee institution's obligation to recognize the PI's original ideas, contributions, and potential rights to some forms of expression and compensation. Issues include maintaining a role for the PI in determining how to take credit for, share and publish results that involve his or her original ideas. Ascribing proper credit can become a thorny issue. This paper provides a framework for addressing situations and disagreements that may occur when a new PI continues the work after the original PI transfers. Included are suggestions for proactively developing institutional mechanisms that address such issues. Considerations include how to develop solutions that comply with the responsible conduct of research, equitably resolve claims regarding reporting of results, and avoid the possibility of plagiarism.

    2015-10-01

    The transition to scientific independence as a principal investigator (PI) can seem like a daunting and mysterious process to postdocs and students - something that many aspire to while at the same time wondering how to achieve this goal and what being a PI really entails. The FENS Kavli Network of Excellence (FKNE) is a group of young faculty who have recently completed this step in various fields of neuroscience across Europe. In a series of opinion pieces from FKNE scholars, we aim to demystify this process and to offer the next generation of up-and-coming PIs some advice and personal perspectives on the transition to independence, starting here with guidance on how to get hired to your first PI position. Rather than providing an exhaustive overview of all facets of the hiring process, we focus on a few key aspects that we have learned to appreciate in the quest for our own labs: What makes a research programme exciting and successful? How can you identify great places to apply to and make sure your application stands out? What are the key objectives for the job talk and the interview? How do you negotiate your position? And finally, how do you decide on a host institute that lets you develop both scientifically and personally in your new role as head of a lab? © 2015 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

    An account is given of the life, scientific contributions, and passing of Laurance David Hall (1938-2009), including his early history and education at the University of Bristol, UK, and the synthesis and NMR spectroscopy of carbohydrates and other natural products during ∼20 years of research and teaching at the University of British Columbia in Vancouver, Canada. Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference. Two memorial services for Professor Hall are remembered.

    This study aimed to determine the prevalence and reproductive impact of Neospora caninum in a herd of semi-free-ranging Père David's deer (Elaphurus davidianus) at a conservation facility, following a suspected abortion storm in 2008. Serum samples (n=103) collected from 60 individuals between 2002 and 2011 were evaluated using competitive ELISA for the detection of N. caninum-specific antibodies. Of the 103 samples, 73 (70.9 per cent) were positive for N. caninum antibodies, with a mean±sd competitive inhibition (CI) of 77.6±19.8 per cent. Thirty (29.1 per cent) samples were seronegative, with mean CI of 15.2±9.70 per cent. A significant negative linear relationship was noted between the proportion of seropositive animals and age (R2=0.228, P<0.001). Calving rates of adult females from 2005 to 2011 ranged from 15.4 per cent to 52 per cent (mean 35.5±11.3 per cent), and did not correlate with mean CI values (Spearman's rank correlation coefficient=0.072, P=0.878). While both horizontal and transplacental transmission are likely contributing to persistent herd seropositivity, the role of N. caninum in reproductive success in this and other populations of endangered ungulates remains to be explored.

    1984-05-01

    The purpose of the Aquatic Species program is to improve the productivity, conversion to fuels, and cost efficiency of aquatic plant species for energy. The emphasis of the program is on developing oil-yielding microalgae which will grow in the saline waters of the desert in the American Southwest. To meet this objective, research is carried out under three tasks: biological, engineering, and analysis. The principal objectives of the biological task are (1) to conduct a comprehensive and complete screening activity that will result in the selection of the best microalgae strains for production of fuels; (2) to establish a gene pool so that species can be improved through agronomic means; and (3) to develop techniques that will result in enhancing the yields of the desired fuel product. Engineering research is concerned with integrating biological concepts with engineering principals to develop the most cost-effective microalgal culture technology. Work is concentrated on developing culture management strategies and required subsystems such as harvesting technologies. Analysis supports the technology development through cost goal determination, resource assessment, and technology evaluation. The program also supports the development of macroalgae culture for methane gas or alcohols. This volume contains progress reports presented by the Aquatic Species Program subcontractors and SERI researchers at the SERI Biomass Program Review held in Boulder, Colorado, April 4, 1984. These reports present and discuss research advances achieved by the program participants during the preceding year. Separate abstracts have been prepared for each report for inclusion in the Energy Data Base.

  12. Investigating MJO Precursors and Initial Stages with Multivariate Principal Oscillation Analysis

    NASA Astrophysics Data System (ADS)

    2015-12-01

    We have applied Principal Oscillation Pattern (POP) analysis to minimally filtered gridded analyses of several variables which can be used as markers of Madden-Julian Oscillation (MJO) initiation. One of the resulting modes is MJO-like, with an 11-pentad period and a 3-pentad decay time. We have separately used a variety of criteria to identify several MJO events during boreal winters 1998-2012 for individual examination. Here we explore how the MJO-like mode evolves during these cases in multiple ways. We track the contributions to that mode by upper- and lower-level zonal winds and latent heating (as proxied by Outgoing Longwave Radiation, OLR), as well as the contributions made by mid-tropospheric temperature (T400) and sea-level pressure (SLP) in the pre-cursor and early stages of the events. We also examine the stochastic forcing of these cases using diagnostics based on fluctuation-dissipation theory, and compare the characteristics of this forcing during the early stages of several MJO events.

  14. Investigation of Inversion Polymorphisms in the Human Genome Using Principal Components Analysis

    2012-01-01

    Despite the significant advances made over the last few years in mapping inversions with the advent of paired-end sequencing approaches, our understanding of the prevalence and spectrum of inversions in the human genome has lagged behind other types of structural variants, mainly due to the lack of a cost-efficient method applicable to large-scale samples. We propose a novel method based on principal components analysis (PCA) to characterize inversion polymorphisms using high-density SNP genotype data. Our method applies to non-recurrent inversions for which recombination between the inverted and non-inverted segments in inversion heterozygotes is suppressed due to the loss of unbalanced gametes. Inside such an inversion region, an effect similar to population substructure is thus created: two distinct “populations” of inversion homozygotes of different orientations and their 1∶1 admixture, namely the inversion heterozygotes. This kind of substructure can be readily detected by performing PCA locally in the inversion regions. Using simulations, we demonstrated that the proposed method can be used to detect and genotype inversion polymorphisms using unphased genotype data. We applied our method to the phase III HapMap data and inferred the inversion genotypes of known inversion polymorphisms at 8p23.1 and 17q21.31. These inversion genotypes were validated by comparing with literature results and by checking Mendelian consistency using the family data whenever available. Based on the PCA-approach, we also performed a preliminary genome-wide scan for inversions using the HapMap data, which resulted in 2040 candidate inversions, 169 of which overlapped with previously reported inversions. Our method can be readily applied to the abundant SNP data, and is expected to play an important role in developing human genome maps of inversions and exploring associations between inversions and susceptibility of diseases.

  8. Ethics of medical care and clinical research: a qualitative study of principal investigators in biomedical HIV prevention research.

    PubMed

    Haire, Bridget G

    2013-04-01

    In clinical research there is a tension between the role of a doctor, who must serve the best interests of the patient, and the role of the researcher, who must produce knowledge that may not have any immediate benefits for the research participant. This tension is exacerbated in HIV research in low and middle income countries, which frequently uncovers comorbidities other than the condition under study. Some bioethicists argue that as the goals of medicine and those of research are distinct, it is a mistake for researchers to assume therapeutic responsibilities while engaging in research. Others propose that there is a duty of care, but disagree as to how this is limited and specified. In this qualitative study, principal investigators from HIV prevention trials discuss their experience of providing medical benefits to participants within the context of conducting research into HIV biomedical prevention technologies. They describe the limitations imposed at times by funders and at times by infrastructure constraints, and canvass the importance of ancillary care provision and capacity building in trial communities. The views of the principal investigators are compatible with the perspective that there is a duty of care, limited by the nature of the research, the depth of the relationship between research and participant, and the capacity of the research site. The therapeutic orientation in HIV prevention trial appears to be indivisible from competent research practise by making concrete and appropriate benefits available to trial participants and their communities that support rather than compete with local infrastructure.

    You finished your PhD, have been a postdoc for a while, and you start wondering, “What's next?” Suppose you come to the conclusion that you want to stay in academia, and move up the ladder to become a principal investigator (PI). How does one reach this goal given that academia is one of the most competitive environments out there? And suppose you do manage to snatch your dream position, how do you make sure you hit the ground running? Here we report on the workshop “P2P - From Postdoc To Principal Investigator” that we organized at ISMB 2012 in Long Beach, California. The workshop addressed some of the challenges that many postdocs and newly appointed PIs are facing. Three experienced PIs, Florian Markowetz (Group Leader, Cambridge Research Institute, Cancer Research UK), Gary Bader (Associate Professor, The Donnelly Centre, University of Toronto), and Philip Bourne (Professor, Skaggs School of Pharmacy and Pharmaceutical Sciences, University of California San Diego), provided insight into the transition from a trainee to PI and shared advice on how to make the best out it.

    National Institutes of Health (NIH) grants are becoming increasingly competitive in the academic research arena. Identifying NIH funding disparities is an important step in improving academic diversity. To examine recent NIH funding trends in dermatology. Retrospective study with linear regression analysis and repeated-measures analysis of variance of all NIH grants awarded to departments of dermatology from fiscal year 2009 to 2014. Funding data were exported from the NIH Research Portfolio Online Reporting Tools Expenditures and Results. Publication data were drawn from Scopus. All NIH-funded principal investigators in dermatology were categorized by their academic degree and sex. The NIH funding trends were compared by investigator degree (MD, PhD, or MD/PhD) and sex. A total of 1292 NIH-funded grants were awarded to dermatology research from fiscal year 2009 through 2014. Adjusted NIH funding for dermatologic research diminished by 4.6% from $67.3 million in 2009 to $64.2 million in 2014, with a nadir of $58.6 million in 2013. Funding for the NIH's Research Project Grant Program (R01) decreased by 21.0% from $43.9 million to $34.7 million during this period. The dollar amount of NIH funding significantly trended down for investigators with an MD degree by $1.35 million per year from $23.6 million in 2009 to $18.4 million in 2014 (P = .02) while there was no significant change in NIH funding for MD/PhD (from $17.6 million in 2009 to $19.8 million in 2014; P = .44) and PhD investigators (from $26.1 million in 2009 to $25.9 million in 2014; P = .74). Similarly, the total dollar amount of R01 grants awarded to principal investigators with only an MD degree trended down by $1.4 million per year from $13.2 million in 2009 to $6.0 million in 2014 (P < .001). The number of female investigators with NIH grants in dermatology trended down significantly compared with the trend of their male counterparts (from 49 women in 2009 to 43 women in 2014 vs from 84

    The monitoring and control of air quality in urban areas is important problem in many European countries. The main air pollutants are observed and a huge amount of data is collected during the last years. In Bulgaria, the air quality is surveyed by the official environmental agency and in many towns exceedances of harmful pollutants are detected. The aim of this study is to investigate the pollution from 9 air pollutants in the town of Dimitrovgrad, Bulgaria in the period of 5 years based on hourly data. Principal Component Analysis (PCA) is used to discover the patterns in the overall pollution and the contribution of the 9 pollutants. In addition the Generalized Path Seeker (GPS) regularized regression method is applied to find dependence of CO (carbon monoxide) with respect to other pollutants and 8 meteorological parameters. It is reported that the CO concentrations are in continuously repeated low level quantities very harmful for human health.

  15. Structural and mechanical properties of alkali hydrides investigated by the first-principles calculations and principal component analysis

    NASA Astrophysics Data System (ADS)

    Settouti, Nadera; Aourag, Hafid

    2016-08-01

    The structural and mechanical properties of alkali hydrides (LiH, NaH, KH, RbH, and CsH) were investigated via first-principles calculations which cover the optimized structural parameters. The density functional theory in combination with the generalized gradient approximation (GGA) were used in this study. From the present study, one could note that alkali hydrides are brittle materials and mechanically stable. It was found that stiffness and shear resistance are greater in LiH than in other hydrides. It is more brittle in nature, and comparatively harder than the other materials under study; it also presents a high degree of anisotropy. The results were then investigated and analyzed with principal component analysis (PCA), which is one of the most common techniques in multivariate analysis, was used to explore the correlations among material properties of alkali hydrides and to study their trends. The alkali hydrides obtained by the first-principles calculations were also compared with the alkaline-earth metal hydrides (BeH2, MgH2, CaH2, SrH2, and BaH2) and discussed in this work.

An evaluation toolkit was developed for Computer and Information Sciences and Engineering(1) Research Experiences for Undergraduates(2) (CISE REU) programs to address the ongoing need for evaluation capacity among principal investigators who manage program evaluation. The toolkit was the result of collaboration within the CISE REU community with the purpose being to provide targeted instructional resources and tools for quality program evaluation. Challenges were to balance the desire for standardized assessment with the responsibility to account for individual program contexts. Toolkit contents included instructional materials about evaluation practice, a standardized applicant management tool, and a modulated outcomes measure. Resulting benefits from toolkit deployment were having cost effective, sustainable evaluation tools, a community evaluation forum, and aggregate measurement of key program outcomes for the national program. Lessons learned included the imperative of understanding the evaluation context, engaging stakeholders, and building stakeholder trust. Results from project measures are presented along with a discussion of guidelines for facilitating evaluation capacity building that will serve a variety of contexts.

  4. Experimenting with wires, batteries, bulbs and the induction coil: Narratives of teaching and learning physics in the electrical investigations of Laura, David, Jamie, myself and the nineteenth century experimenters. Our developments and instruments

    Physics is conventionally taught as a fixed curriculum which students must master. This thesis changes that: curriculum emerges from what learners try and question in experiments they invent. The thesis narrates: three adult students exploring wires, batteries and bulbs with me as teacher; nineteenth century investigations of electromagnetism; my laboratory work replicating historic instruments. In each case, learning arose through activity with materials. Evidences of this are analyzed within narratives and reflections. I used teaching-research, a method developed by Duckworth from Piaget's clinical interviewing, to research and simultaneously extend students' evolving understandings. What I learned through questioning students informed my next interactions; what they learned extended their experimenting. Similarly, I researched historical accounts interactively: improvising experiments to develop my understandings. Studying my own learning deepened my interpretations of students' learning. My students Laura, David and Jamie experimented by: soldering bulbs to wires, making series and parallel circuits, inserting resistive wire that dimmed bulbs, conducting electricity through salt water They noticed bulb brightness and battery heat, compared electricity's paths, questioned how voltage and current relate. They inferred electricity's effects manifest magnitudes of material properties. They found their experiences while learning were inseparable from what they learned. I researched investigations connected with Cavendish's leather fish, Galvani's frogs, Schweigger's wire spiraled around a compass needle, Henry's electromagnets, Faraday's induction ring, induction devices of Page, Callan, Hearder. Experimentally, I made galvanometers, electromagnets, induction rings, induction coil. I observed effects of electromagnetism, internal resistance, induced sparking. Across these investigations, learning developed with instrumental innovations; confusions were productive

    the ones first developed in the setting of the Sherrington--Kirkpatrick model of spin glasses. What this small anecdote hints at is the vastness of the terrain over which research on spin glasses is having a deep and lasting impact. As scientists we are, I think it's fair to say, at least partially motivated by a desire to receive some recognition for our work, some evidence that it has been engaging and stimulating to others in the field. But David's work far transcends this model, being pivotal not only to researchers in the originally-intended domain of rather obscure magnetic alloys, but also far, far beyond: from neuroscience and biological information processing, to the social sciences, including economics, and on to probability theory, computer science, the next generation of optimization algorithms, and the entire field of complexity theory. Indeed, one can regard spin glasses in the guise of the Sherrington-Kirkpatrick model as a conceptual version of the silicon revolution: a curiosity-driven scientific endeavour that continues to catalyse utterly unanticipated progress over far-flung domains. David captured it all perfectly in the title of his 2001 Bakerian Lecture: 'Magnets, microchips, memories and markets: [the] statistical physics of complex systems.' Many of us would consider ourselves wonderfully fortunate if our work were to have just a small fraction of the impact that David's has. Moreover, the scientific panorama revealed by investigations stimulated by David's work is beautiful, shocking and inspiring, a panorama broader still than condensed matter theory or even physics itself. So, when our spirits are down and our brows furrowed by some painful integral or a bug in our computer code, let us remember to pause and revel in the astonishing confluence of scientific themes that the Sherrington-Kirkpatrick model and its associates capture. To echo a view I first heard from Giorgio Parisi: I'm not sure if there is anything more rich or surprising in

  6. A Star of David catenane

    We describe the synthesis of a [2]catenane that consists of two triply entwined 114-membered rings, a molecular link. The woven scaffold is a hexameric circular helicate generated by the assembly of six tris(bipyridine) ligands with six iron(II) cations, with the size of the helicate promoted by the use of sulfate counterions. The structure of the ligand extension directs subsequent covalent capture of the catenane by ring-closing olefin metathesis. Confirmation of the Star of David topology (two rings, six crossings) is provided by NMR spectroscopy, mass spectrometry and X-ray crystallography. Extraction of the iron(II) ions with tetrasodium ethylenediaminetetraacetate affords the wholly organic molecular link. The self-assembly of interwoven circular frameworks of controlled size, and their subsequent closure by multiple directed covalent bond-forming reactions, provides a powerful strategy for the synthesis of molecular topologies of ever-increasing complexity.

    Within the fields of medicine and sociology, the descriptor "profession" (along with its brethren: profession, professionalization, and professionalism) has had a rich etymological history, with terms taking on different meanings at different times-sometimes trespassing into shibboleth and jargon. This etymological journey has co-evolved with the career of David Mechanic to whom this issue of the Journal of Health Politics, Policy and Law is devoted. We exploit a provocative metaphor applied to Mechanic's work on the challenges facing medicine as a profession as a playful exegesis on what we call "profession" to excavate an ensconced and encrusted domain of health jargon operating at the tensive interface of society and modern medical work.

    While attending medical school at McGill, David Hubel developed an interest in the nervous system during the summers he spent at the Montreal Neurological Institute. After heading to the United States in 1954 for a Neurology year at Johns Hopkins, he was drafted by the army and was assigned to the Neuropsychiatry Division at the Walter Reed Hospital, where he began his career in research and did his first recordings from the visual cortex of sleeping and awake cats. In 1958, he moved to the lab of Stephen Kuffler at Johns Hopkins, where he began a long and fruitful collaboration with Torsten Wiesel. Born in Sweden, Torsten Wiesel began his scientific career at the Karolinska Institute, where he received his medical degree in 1954. After spending a year in Carl Gustaf Bernhard's laboratory doing basic neurophysiological research, he moved to the United States to be a postdoctoral fellow with Stephen Kuffler. It was at Johns Hopkins where he met David Hubel in 1958, and they began working together on exploring the receptive field properties of neurons in the visual cortex. Their collaboration continued until the late seventies. Hubel and Wiesel's work provided fundamental insight into information processing in the visual system and laid the foundation for the field of visual neuroscience. They have had many achievements, including--but not limited to--the discovery of orientation selectivity in visual cortex neurons and the characterization of the columnar organization of visual cortex through their discovery of orientation columns and ocular-dominance columns. Their work earned them the Nobel Prize for Physiology or Medicine in 1981, which they shared with Roger Sperry. Copyright © 2012 Elsevier Inc. All rights reserved.

    Following a description about the characteristics of akinetic mutism (AM) and how it differs from locked-in syndrome (LIS) and a disorder of consciousness (DOC), we present the case of David, a 71-year-old man with AM. David sustained a stroke following a middle cerebral artery (MCA) thrombus. A CT scan at the time detected old ischaemic infarcts affecting the right frontal lobe, the left occipital lobe and the left parietal lobe so David had bilateral brain damage. Initially thought to have a DOC, further neuropsychological assessments administered when David had improved a little, resulted in the diagnosis of AM. Although David spoke little, when he did speak, his words and phrases were well articulated, grammatical and with appropriate intonation. He was alert and visually aware and he was not paralysed. We discuss whether the diagnosis was correct and address the difficulties in assessing such patients.

  14. Obituary: David Q. Wark, 1918-2002

    McMillin, Larry Max

    2003-12-01

    David Q. Wark, a research meteorologist at the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA/NESDIS) and its predecessor organizations for 55 years, died of cancer 30 July 2002. He will be long remembered for his seminal contributions to the weather satellite program. A pioneer in the use of satellite sensors to provide observations of the Earth's environment for application to weather forecasting and atmospheric science, Dr. Wark was noted for his brilliant insights, dedication, and exceptional scientific achievements. He developed many of the theoretical and experimental techniques on which NOAA's current multi- billion-dollar meteorological satellite program is based. In the 1960's and early 1970's, he and his NOAA colleague Donald Hilleary were the motivating force and principal investigators for the first satellite instruments dedicated to sounding the atmosphere for temperature and water-vapor. These instruments included the Satellite Infra-Red Spectrometer (SIRS)-A and -B and the Vertical Temperature Profile Radiometer (VTPR), which were flown on NASA's Nimbus satellites and NOAA's ITOS-D satellites, respectively. With colleague Henry Fleming, he formulated the radiative transfer equation that quantifies the spectral radiances of the Earth and its atmosphere (measured at satellite altitude) and inverted that equation mathematically to infer the atmospheric temperature profile from satellite-based measurements of those radiances. A difficulty they had to overcome was that the mathematical problem is ill-posed, i.e., it admits of an infinite number of solutions. They arrived at a unique solution via an innovative application of a-priori information on the atmospheric state. This work was described in the landmark 1965 Wark and Fleming paper in the American Meteorological Society's Monthly Weather Review. From that early period until just weeks before his death, Dr. Wark continued

  4. Investigation of probabilistic principal component analysis compared to proper orthogonal decomposition methods for basis extraction and missing data estimation

    NASA Astrophysics Data System (ADS)

    Lee, Kyunghoon

    To evaluate the maximum likelihood estimates (MLEs) of probabilistic principal component analysis (PPCA) parameters such as a factor-loading, PPCA can invoke an expectation-maximization (EM) algorithm, yielding an EM algorithm for PPCA (EM-PCA). In order to examine the benefits of the EM-PCA for aerospace engineering applications, this thesis attempts to qualitatively and quantitatively scrutinize the EM-PCA alongside both POD and gappy POD using high-dimensional simulation data. In pursuing qualitative investigations, the theoretical relationship between POD and PPCA is transparent such that the factor-loading MLE of PPCA, evaluated by the EM-PCA, pertains to an orthogonal basis obtained by POD. By contrast, the analytical connection between gappy POD and the EM-PCA is nebulous because they distinctively approximate missing data due to their antithetical formulation perspectives: gappy POD solves a least-squares problem whereas the EM-PCA relies on the expectation of the observation probability model. To juxtapose both gappy POD and the EM-PCA, this research proposes a unifying least-squares perspective that embraces the two disparate algorithms within a generalized least-squares framework. As a result, the unifying perspective reveals that both methods address similar least-squares problems; however, their formulations contain dissimilar bases and norms. Furthermore, this research delves into the ramifications of the different bases and norms that will eventually characterize the traits of both methods. To this end, two hybrid algorithms of gappy POD and the EM-PCA are devised and compared to the original algorithms for a qualitative illustration of the different basis and norm effects. After all, a norm reflecting a curve-fitting method is found to more significantly affect estimation error reduction than a basis for two example test data sets: one is absent of data only at a single snapshot and the other misses data across all the snapshots. From a numerical

  5. David MacKay's wooden blocks

    NASA Astrophysics Data System (ADS)

    Skilling, John

    2017-06-01

    This paper is dedicated to the memory of Professor Sir David MacKay FRS. In his inspiring last talk, MacKay discussed the problem of packing his young son's identical wooden blocks, of size 2×1×1. How many ways are there of packing n3/2 such blocks into a cubical box of volume n3? This is the same problem as finding the entropy of cubic packing of dimeric molecules, so the investigation is not merely childish. Here, I use this example as an exemplar of the use of nested sampling in computational inference. In this analogy, the posterior covers the "glassy" arrangements of non-overlapping blocks in the box, whereas the prior represents the wider set of unrestricted model configurations. The required number of possible glass states is the compressive prior-to-posterior fraction of the known number of model configurations. And the compression (as logarithm) is immediately available from the number of equilibrating iterations in nested sampling. The clarity of this example offers useful lessons for computational inference more generally.

    Bash, Frank N.

    2005-12-01

    David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory

  12. Microstructural investigations of principal slip zones in carbonates, examples from shallow crustal strike-slip faults in the Northern Calcareous Alps (Austria)

    NASA Astrophysics Data System (ADS)

    Bauer, Helene; Grasemann, Bernhard; Decker, Kurt

    2014-05-01

    Faults in the upper crust can move episodically by seismic deformation (individual earthquake ruptures) and/or continuously by aseismic creep deformation. In carbonate fault zones, several studies have shown that seismic deformation produces very narrow principal slip zones (cm to mm wide) that accommodate most of the fault displacement during an individual earthquake. Within these principal slip zones, ultracataclasites containing the principal slip surface, fluidization of ultracataclastic sub-layers and clast cortex grains have been proposed to be characteristic for seismic slip. In contrast, pressure solution has been proposed as a mechanism of aseismic sliding along a fault. Spaced cleavage solution planes and associated veins indicate diffusive mass transfer and precipitation in pervasive vein networks. At micro-scale, calcite CPO in fine-grained matrix of principal slip zones has been suggested to result from post-seismic pressure solution creep. Here, we present field data from the Salzchtal-Ennstal-Mariazell-Puchberg (SEMP) fault system (Austria) to interpret the principal slip zones with regard to possible indicators of seismic or aseismic deformation. We investigated exhumed, ancient sinistral strike-slip faults in dolomite and limestone that formed during eastward lateral extrusion of the Eastern Alps during Oligocene to Lower Miocene. The faults belong to a system of convergent strike-slip duplexes that developed at a restraining bend on an eastern segment of the SEMP-fault system. Distinct fault cores contain cataclastic fault rocks differing in textural complexity. Microstructural analysis of cataclastic fault rocks was done using both, optical and electron microscopy. Microstructures reveal several cataclastic types that can be interpreted in terms of different stages of cataclastic evolution. Coarser grained, well cemented cataclasites underlie fine grained ultracataclastic layers. For at least two of the faults, cataclasites containing clast

  13. The vision of David Marr.

    PubMed

    Stevens, Kent A

    2012-01-01

    Marr proposed a computational paradigm for studying the visual system, wherein aspects of vision would be amenable to study with what might be regarded a computational-reductionist approach. First, vision would be cleaved into separable 'computational theories', in which the visual system is characterized in terms of its computational goals and the strategies by which they are carried out. Each such computational theory could then be investigated in increasingly concrete terms, from symbols and measurements, to representations and algorithms, to processes and neural implementations. This paradigm rests on some general expectations of a symbolic information processing system, including his stated principles of explicit naming, modular design, least commitment, and graceful degradation. In retrospect, the computational framework also tacitly rests on additional assumptions about the nature of biological information processing: (1) separability of computational strategies, (2) separability of representations, (3) a pipeline nature of information processing, and that (4) the representations employ primitives of low dimensionality. These assumptions are discussed in this retrospective.

  17. David Gill: clock maker to global astronomer

    NASA Astrophysics Data System (ADS)

    Haley, P. A.

    2014-04-01

    Reduction in the uncertainty of physical measurements underpinned many advances in solar and stellar parallax, the determination of longitude, geodesy, and the accurate mapping of the heavens using celestial photography in the late nineteenth century. A pioneer in these areas, who successfully made the transition from clock maker in Aberdeen to H.M. Astronomer at the Cape of Good Hope was David Gill (1843-1914); Sir David Gill, K.C.B. from 1900. This paper celebrates the first third of Gill's career in astronomy and geodesy up to the time he was made redundant from Dun Echt Observatory at the end of 1875. It highlights how his horological skills were applied to telescope design and also how his aspirations to become a global astronomer started. The paper is timed to coincide with Gill's centenary anniversary year - he died 24 January 1914.

    The attitudes of 211 students at a university in Mississippi were investigated both before and after seeing the Public Broadcasting Film Who Is David Duke? The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan.

  20. Investigation of the influence of FDM operating parameters on dynamic force response using IV-optimal design and principal component analysis

    To improve the functionality in regards to manufacturing products at low cost, several innovative additive manufacturing processes have been developed. Fused deposition modeling (FDM) is one the most prominent additive manufacturing processes for producing plastic products. Referring to the quality and functionality, there are many FDM process conditions contributing to the occurrence of poor quality and functionality of FDM manufactured products. Therefore, the effect of the build parameters on the functionality of FDM produced products need to be examined. In this study, an attempt has also been made to investigate the critical processing parameters affecting dynamic mechanical response of plastic part processed by FDM technology using IV-optimal response surface method coupled with principal component analysis technique. The results obtained from this study can be used in the future as a guide for future in selecting the appropriate process conditions before the manufacturing process of the product take place.

He also built magnetic compasses and surveying instruments. The finest examples of his craftsmanship are considered two orreries, mechanical solar systems. In terms of astronomical observations, his best-known contribution was his observation of the transit of Venus in 1769. Rittenhouse constructed the first diffraction grating. Working as Treasurer of Pennsylvania throughout the Revolution, he became the first director of the Mint in 1792. Astronomical observations in later life included charting the position of Uranus after its discovery.

  3. Obituary: David Fulmer Bender, 1913-2004

    Miller, Sylvia L.

    2004-12-01

    David Fulmer Bender died in San Diego, California, on 13 September 2004, at the age of 91. His heart stopped suddenly while he was dancing. His pioneering work in establishing comprehensive, computer-accessible ephemerides of asteroids and comets found many applications, including the first-ever visit to an asteroid, Gaspra, by an interplanetary spacecraft. Dave was born in Reno, Nevada, on 10 February 1913, to Homer Charles Bender and Susan Bowers Bender. The family moved to Spokane, Washington, while Dave was very young. His father was a civil engineer and a graduate of MIT, who helped design bridges and dams throughout the Northwest, including the Grand Coolie Dam. Dave had a brother, Phillip (now deceased), who was one year younger. Advancing rapidly in the Spokane school system, Dave finished high school when he was 15 years old. At 16 he moved to Pasadena, California, and began his studies at the California Institute of Technology (Caltech). In addition to pursuing his course work, he was active in track and football, a tendency toward physical exercise that stayed with him for the rest of his life. It was probably during these years that Dave heard a lecture by Albert Einstein, as mentioned to colleagues many years later. Dave received a BS degree in physics in 1933, an MS in 1934, and a PhD in 1937, all from Caltech. His dissertation was entitled, "The Index of Refraction of Air in the Photographic Infrared." During his sophomore year he found his way to Pomona College in Claremont, California, where he met his future wife, Elizabeth Boyden at a social gathering. They were married in 1935. Dave's academic career spanned the years from 1937 to 1970, initially at Louisiana State University, Vanderbilt University, and then Fisk. As a life-long pacifist and conscientious objector, Dave served alternate duty during World War II. In 1946 he joined the faculty of the physics department at Whittier College in California, where he became the department chair and

It was with great sadness that family, friends, and colleagues gathered together for his memorial service on Saturday, October 17, 2009, at the Middletown United Methodist Church in Maryland. As a NCI scientist since 1986, Dave studied the molecular mechanisms of infection and replication of a number of different types of retroviruses. Dave became an internationally known expert on human T cell lymphotrophic viruses type 1 and 2 (HTLV-1 and HTLV-2) and served on the editorial boards of Virology and Retrovirology. His most recent studies focused on the mechanisms of HTLV-1 virion morphogenesis, transmission, and replication.

    The Iwokrama International Centre for Rain Forest Conservation in Guyana is headed by Australian forester David Cassells who is also chairman of the Advisory Group for the World Conservation Union Forest Conservation Program. He states that this program is different from other projects to conserve tropical forests since it focuses on financial sustainability and self-sufficiency. He also plans that the revenue for the center will come from a mixture of eco-forestry with certified logging, ecotourism, sustainable production of non-timber products such as vines and latexes, bioprospecting, and the sale of forest management expertise. He further added that the program's success could change the way people value and use tropical forests.

    David Lukens Reasoner, former head of NASA's Ionospheric Physics branch, died on April 21, 1992. Reasoner was born July 1, 1941. He worked tirelessly to expand NASA's Space Physics Division, bringing his deep experience and personal expertise to bear on the challenges of growth.During the magical period of the late 1950s and early 1960s when America turned its eyes toward space and the Moon, David Lukens Reasoner journeyed north from the nearby Texas town of Dickinson to Rice University with an idea of getting involved in exploring the frontiers of space. He pursued a course of study in electrical engineering and received a bachelor's degree in 1963 and a master's degree in 1964. In the early 1960s, the Space Science Department at Rice was formed, and President John Kennedy visited to say that America chose to go to space not because it is easy but because it is hard and because it would require the very best talents of our nation to succeed. Dave Reasoner was one of those talented people. His excellence in electrical engineering and physics, combined with his natural abilities in the laboratory, suited him ideally for building the machines of space. As a student, he built sounding rocket payloads and multiple instruments for satellites and experiment packages that were placed on the Moon by the Apollo astronauts. He completed his doctoral degree in space science in 1968. It was in these early thrilling days of space exploration that I first met Dave, beginning a friendship and collegial relationship that was to last 27 years.

    The effort needed for comprehensive climate change education is far greater than any one institution, education sector, or even federal agency can handle. Recognizing a need to synergistically combine efforts, NSF, NASA, and NOAA have created a collaborative community of their climate change education principal investigators (PIs) through tri-agency coordination. The goals of this tri-agency collaboration are to leverage existing resources, minimize duplicate efforts, and facilitate communication among this emergent community of scientists and educators. NASA, NOAA, and NSF work together to strategically coordinate and support a portfolio of projects focused on climate literacy and education in formal and informal learning environments. The activities of the tri-agency collaboration, including annual meetings for PIs, a catalog of the agencies collective investments in climate change education and the ongoing development of a nascent common evaluation framework, have created a strong national network for effectively engaging diverse audiences with the principles of climate literacy (see Eos Vol. 92, No. 24, 14 June 2011). Last year, after 3 years of active collaboration, similar programs underway at other U.S. Global Change Research Program agencies: the EPA, National Institutes for Environmental Health Sciences, and USDA, were engaged in the collaboration. And, in an attempt to understand the interests of the private sector in this arena, conversations have begun with private philanthropic organizations. This year, as many of the funded projects are maturing, the PI meeting will have a focus on bringing this community together to create a science-theme based tangible outcome that can move the field of climate change education forward. Additional outcomes from this PI meeting will be presented as well as the challenges that were encountered in bringing together institutions with diverse missions, and approaches developed to ensure all parties feel they

  18. Systematic investigation of the principal and first secondary maxima of ultrashort optical pulses focused by a high numerical aperture aplanatic lens

    Lindlein, Norbert; Loosen, Florian; Fries, Sebastian

    2015-09-01

    The electromagnetic field in the focus of an ideal aplanatic lens with high numerical aperture, which is illuminated by an ultrashort optical pulse and plane wave front, is simulated by taking the vectorial Debye integral and the coherent superposition of a frequency spectrum of monochromatic waves. The behavior of the principal maxima and the first secondary maxima as function of the numerical aperture (NA) and the pulse duration T is investigated systematically for light incident with linear polarization. First, one would not expect remarkable deviations from the stationary case. But also this simple system of an ideal aplanatic lens without any chromatic or monochromatic aberrations (of course only simple from the point of theory, but not at all from the point of practical realization) shows some remarkable results. If the NA (in vacuum) tends to the limiting case of 1.0 the maximum value of |E|2 increases faster than expected from the scalar theory (Airy disc) with a maximum deviation of about 13%. The second effect really comes from very short pulses, i.e. very small values T. Then, the value of |E|2 compared to the expected linear increase with 1/T decreases slightly (only less than 2%), but systematically for all NAs. Even more interesting is the dependence of the height of the first secondary maxima along the x-axis and y-axis on the NA and 1/T. It can be seen that along both axes the first secondary maxima nearly vanish for very short pulses, i.e. large values 1/T.

    Principal components analysis (PCA) is a standard tool in multivariate data analysis to reduce the number of dimensions, while retaining as much as possible of the data's variation. Instead of investigating thousands of original variables, the first few components containing the majority of the data's variation are explored. The visualization and statistical analysis of these new variables, the principal components, can help to find similarities and differences between samples. Important original variables that are the major contributors to the first few components can be discovered as well.This chapter seeks to deliver a conceptual understanding of PCA as well as a mathematical description. We describe how PCA can be used to analyze different datasets, and we include practical code examples. Possible shortcomings of the methodology and ways to overcome these problems are also discussed.

    Previous work has shown that gas phase atomic chlorine radicals (Cl*) can influence tropospheric photochemistry, including concentrations of volatile organic compound (VOC) and ozone. These radicals are produced through both gas phase and heterogeneous pathways. This work presents computational and experimental investigation into the heterogeneous reactions of chloride aerosols. An overview of a sensitivity analysis of the physical parameters involved in the heterogeneous production of nitryl chloride (ClNO2) (R1-R5) will comprise the computational work presented. NO2(g) + NO3(g) ↔ N2O5(g) (R1) N2O5(aq) ↔ N2O5(aq) (R2) N2O5(aq) ↔ NO2+(aq) + NO3-(aq) (R3) NO2+(aq) + H2O(aq) → H3O+(aq) + HNO3(aq) (R4a) NO2+(aq) + Cl- → ClNO2 + H2O(aq) (R4b) NO3-(aq) + H+ ↔ HNO3+(aq) (R5) Relative parameters include the reactive uptake coefficient, ClNO2 yield, particle surface area, and gas phase concentrations of VOCs and NOx. The sensitivity analysis results were generated through photochemical box modeling and focus on the production of ClNO2 and impacts to ozone production. Results were compared to a base case scenario in which all heterogeneous reactions were absent. Parameter values reaching the upper limits reported in the literature were tested, and results indicate that ClNO2 chemistry can potentially change peak O3 concentrations by -10.5% to 27%. NOx availability was also found to play an important role. Experimental results of the heterogeneous reaction between OH* and particulate chloride (R6-R7) will also be discussed. The mechanism is shown below, and OH***Cl- represents an intermediate species forming at the particle surface. OH(g) + Cl-(aq) → OH***Cl-(aq) (R6) 2OH***Cl-(aq) → Cl2,g + 2OH-(aq) (R7) Environmental chamber experiments involving the exposure of NaCl aerosol particles to typical atmospheric conditions (HOx, NOx, O3 and UV radiation) were performed. A 10 cubic meter teflon reaction chamber equipped with UV lights was used to contain the

    David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community. Band showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, Band continued as a graduate student in Physics at Harvard University. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Jonathan Grindlay. His dissertation (1985) entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts," according to Grindlay who remained a personal friend and colleague of Band's. Following graduate school, Band held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. Band became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function." After the CGRO mission ended, Band moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned

    Clostridium perfringens is an important pathogen causing sudden death syndrome, necrotic enteritis, and gas gangrene in ruminants, especially some deer species. Père David's deer (Elaphurus davidianus) is one of the world's rare species and is an endangered and protected species in China. Some Père David's deer in the Chinese Shishou Père David's Deer Preserve died due to C. perfringens infection. We investigated the toxin types and C. perfringens enterotoxin-positive (cpe(+)) strains of isolated C. perfringens in Père David's deer in China. We collected 155 fecal samples from the Beijing Nanhaizi Père David's Deer Park and the Jiangsu Dafeng Père David's Deer National Nature Reserve between July 2010 and July 2011. Bacteria isolated using blood agar and mannitol agar plates were identified by Gram staining and nested PCR for 16S rRNA. We isolated C. perfringens from 41 fecal samples and used PCR amplification of five toxin genes to identify the toxinotypes and the cpe(+) strains of C. perfringens. Twenty-one isolates were type A, 15 were type E, and five were type D. Fifteen isolates were cpe(+) strains, including eight that were type A and seven that were type E.

    Correlation analysis in conjunction with principal-component and multiple-regression analyses were applied to laboratory chemical and petrographic data to assess the usefulness of these techniques in evaluating selected physical and hydraulic properties of carbonate-rock aquifers in central Pennsylvania. Correlation and principal-component analyses were used to establish relations and associations among variables, to determine dimensions of property variation of samples, and to filter the variables containing similar information. Principal-component and correlation analyses showed that porosity is related to other measured variables and that permeability is most related to porosity and grain size. Four principal components are found to be significant in explaining the variance of data. Stepwise multiple-regression analysis was used to see how well the measured variables could predict porosity and (or) permeability for this suite of rocks. The variation in permeability and porosity is not totally predicted by the other variables, but the regression is significant at the 5% significance level. ?? 1993.

    Korn, D

    1995-04-01

    When David Korn, MD, was named dean of the Stanford University School of Medicine on October 9, 1984, he assumed leadership of a world class research institution. Stanford was at the forefront of medicine in the areas of transplantation and oncology, and the steady influx of privately insured patients had generated a net operating surplus of $17 million in that year alone. However, in the same issue of the Stanford University Hospital newsletter which announced the selection of Korn as Dean, a small article appeared on a new prospective payment system based on diagnosis-related groups (DRGs). The article stated that the new system had begun smoothly, though some payments for cost outliers had been delayed. Other cost containment measures soon followed, most notably the implementation of managed care, and by 1990, Stanford was $14 million in the red. Buffeted by changes in medical reimbursement, competition with less costly hospitals, and a nasty squabble with Congress over indirect research costs, Stanford has been on the frontlines of a struggle now confronting many academic medical centers. After successfully consolidating the university's clinical services into a unified Stanford Health System, Korn announced that he would be stepping down as Dean on April 1. Interviewed in his office in Palo Alto, Korn reflected on the difficulties of dealing with managed care, the current financial state of the institution, and what Stanford's experience may predict for other academic medical centers.

    David J. Hofmann, a pioneer in stratospheric aerosol and ozone research, passed away in Boulder, Colo., on 11 August 2009. He was 72. Dave, a frequent contributor to AGU publications and meetings, was elected an AGU Fellow in 2006. His long and prolific scientific career was, as he would say, simple in concept: Make a long-term commitment to specific measurements, pay attention to the details, and focus on the important issues that the measurements raise. This is simple in concept yet challenging to maintain in a world of short-term contracts and budgets. That Dave sustained and led key measurement programs through 25 years at the University of Wyoming (UW), in Laramie, and 17 years with the U.S. National Oceanic and Atmospheric Administration's (NOAA) Climate Monitoring and Diagnostics Laboratory (CMDL, which became the Global Monitoring Division (GMD) of NOAA's Earth System Research Laboratory) in Boulder, speaks volumes about the scientific and societal benefits that have resulted from his work. Most of the measurement programs he initiated, and the instruments he helped develop for them, continue today as testament to the value of his focus and lasting influence.

  1. From principal curves to granular principal curves.

    PubMed

    Zhang, Hongyun; Pedrycz, Witold; Miao, Duoqian; Wei, Zhihua

    2014-06-01

    Principal curves arising as an essential construct in dimensionality reduction and data analysis have recently attracted much attention from theoretical as well as practical perspective. In many real-world situations, however, the efficiency of existing principal curves algorithms is often arguable, in particular when dealing with massive data owing to the associated high computational complexity. A certain drawback of these constructs stems from the fact that in several applications principal curves cannot fully capture some essential problem-oriented facets of the data dealing with width, aspect ratio, width change, etc. Information granulation is a powerful tool supporting processing and interpreting massive data. In this paper, invoking the underlying ideas of information granulation, we propose a granular principal curves approach, regarded as an extension of principal curves algorithms, to improve efficiency and achieve a sound accuracy-efficiency tradeoff. First, large amounts of numerical data are granulated into C intervals-information granules developed with the use of fuzzy C-means clustering and the two criteria of information granulation, which significantly reduce the amount of data to be processed at the later phase of the overall design. Granular principal curves are then constructed by determining the upper and the lower bounds of the interval data. Finally, we develop an objective function using the criteria of information confidence and specificity to evaluate the granular output formed by the principal curves. We also optimize the granular principal curves by adjusting the level of information granularity (the number of clusters), which is realized with the aid of the particle swarm optimization. A number of numeric studies completed for synthetic and real-world datasets provide a useful quantifiable insight into the effectiveness of the proposed algorithm.

    A survey on 68 dairy farms was carried out to evaluate the ensiling procedures adopted to store corn silage. Samples from core, lateral and apical zones of the feed-out face of silos were analysed. A principal factor analysis (PFA) was carried out on the entire database (196 silage samples and 36 variables) and 11 principal factor components (PCs) were retained and interpreted. Ensiling procedures influenced the area exposed to risk of air penetration. Cores had higher dry matter, starch and lactic acid content or lower pH, fibre, propionate and butyrate concentrations than peripheral samples (P < 0.05). The highest (P < 0.05) mycophenolic acid and roquefortina C concentrations were detected in lateral samples. Chemical and digestibility variables loaded on two PCs; four PCs were characterized by end-products associated with clostridia, heterolactic, homolactic and aerobic fermentations; two PCs were associated with mycotoxins, whereas three PCs explained ensiling procedures. The main quality traits of corn silages differed throughout the entire silo face. Minimization of the area exposed to risk of air penetration represents the best strategy to preserve the nutritional value and safety of corn silages. PFA allowed a clusterization of original variables into 11 PCs, appearing able to discriminate well and poorly preserved corn silages. © 2015 Society of Chemical Industry.

  14. Mental disorder that afflicted King David the Great.

    PubMed

    Ben-Noun, Liubov

    2004-12-01

    This research uses the tools of modern medical science to study ancient descriptions of the symptoms suffered by King David. Biblical texts were examined, with a close study of verses relating to the mental disorder that afflicted King David, the second and greatest King of Israel, who ruled more than 3525 years ago. We include no commentaries, but refer only to the words of the Bible exactly as written. Evaluation of the passages referring to King David indicated that he was afflicted by some mental disorder, and among the many possibilities major depression, dysthymia and minor depression are the most likely. Of these diagnoses, major depression seems the most acceptable. This report suggests that the roots of contemporary psychiatry can be traced back to Biblical times.

  15. Recovery of handwritten text from the diaries and papers of David Livingstone

    NASA Astrophysics Data System (ADS)

    Knox, Keith T.; Easton, Roger L., Jr.; Christens-Barry, William A.; Boydston, Kenneth

    2011-03-01

    During his explorations of Africa, David Livingstone kept a diary and wrote letters about his experiences. Near the end of his travels, he ran out of paper and ink and began recording his thoughts on leftover newspaper with ink made from local seeds. These writings suffer from fading, from interference with the printed text and from bleed through of the handwriting on the other side of the paper, making them hard to read. New image processing techniques have been developed to deal with these papers to make Livingstone's handwriting available to the scholars to read. A scan of the David Livingstone's papers was made using a twelve-wavelength, multispectral imaging system. The wavelengths ranged from the ultraviolet to the near infrared. In these wavelengths, the three different types of writing behave differently, making them distinguishable from each other. So far, three methods have been used to recover Livingstone's handwriting. These include pseudocolor (to make the different writings distinguishable), spectral band ratios (to remove text that does not change), and principal components analysis (to separate the different writings). In initial trials, these techniques have been able to lift handwriting off printed text and have suppressed handwriting that has bled through from the other side of the paper.

  16. Genetic analysis of Père David's x red deer interspecies hybrids.

    PubMed

    Tate, M L; Goosen, G J; Patene, H; Pearse, A J; McEwan, K M; Fennessy, P F

    1997-01-01

    Interspecies hybrids provide unique opportunities for fundamental genetic analyses and for genetic improvement of farmed deer. We have bred F1 hybrids by artificial insemination of red deer hinds (Cervus elaphus) with semen from Père David's deer (Elaphurus davidianus). The male and female F1 Père David deer x red deer hybrids were fertile and in matings with red deer have produced over 300 viable backcross hybrids. DNA was collected from the backcross progeny as an international reference panel for gene linkage mapping and to investigate associations between segregating species-specific genetic markers and phenotypic traits. We have measured a range of phenotypic traits in the backcross hybrids and red deer. Several traits appear suitable for genetic analysis using mapped genetic markers, including gestation length, growth rate, live weight, head morphometrics, and tail length. Typically these traits show a large difference between Père David's deer and red deer and a high variance in the backcross so that many individuals have a phenotype outside the range observed in red deer.

  12. Chella David: a lifetime contribution in translational immunology.

    PubMed

    Gershwin, M Eric; Shoenfeld, Yehuda

    2011-09-01

    Immunology, like most scientific disciplines, is filled with buzz words. One such buzz word or term has been coined "translational immunology". Indeed, translational research is amongst the most popular expressions used to justify the use of basic research in the hopes that such research will lead to solutions to clinical problems. In fact, no such justification is needed and some of the most important observations in clinical medicine have been derived from basic science; basic science that had no idea at its time of its usefulness in clinical medicine. This special issue is devoted to Chella David. Chella's contributions in immunology have been legion. Before inbred mice became popular, long before multi-million dollar companies were developed to develop such models, Chella David was hard at the bench studying the genetics of the murine immune system and the importance of such mouse models in autoimmune diseases. Importantly, Dr. David provided animals without strings, without the burdens of MTAs, that now impede research. Chella has been generous with his time, with his reagents, and has been a caring and devoted mentor to generations of students. This issue is part of our series to recognize autoimmunologists and dedicated themes that include papers in multiple disciplines of immunology, but especially are focused on cutting-edge applications that will improve clinical therapeutics. Chella David, at age 75, is an athlete in immunology and still keeps going with the same enthusiasm as manifest as a young post-doc. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Tate, M.L.; Mathias, H.C.; Penty, J.M.; Hill, D.F.; Fennessy, P.F.; Dodds, K.G.

    1995-03-01

    Three male F{sub 1} hybrids between Pere David`s deer and red deer were mated to red deer to produce 143 backcross calves. The pedigrees are a rare example of a fertile hybrid between evolutionarily divergent species. We examined the use of these families for genetic mapping of evolutionarily conserved (Type I) loci by testing for genetic linkage between five species-specific protein variants and 12 conserved DNA probes. Two probes were homologous, and the remainder syntenic, to the protein coding loci in cattle or humans. Using six restriction enzymes, each DNA probe detected one or more restriction fragments specific to Pere David`s deer. Linkage analyses among the species-specific variants placed the loci into four linkage groups within which linkage between adjacent loci and gene order was supported by a LOD > 3. Southern and protein analysis of LDHA and ALB provided identical segregation data. These linkage groups were consistent with the cattle gene map and provide new information for comparing the gene maps of ruminants, humans and mice. The deer hybrids are an important new resource that can contribute to the comparative analysis of the mammalian genome. 68 refs., 2 figs., 2 tabs.

  20. Integrated data management for clinical studies: automatic transformation of data models with semantic annotations for principal investigators, data managers and statisticians.

    PubMed

    Dugas, Martin; Dugas-Breit, Susanne

    2014-01-01

    Design, execution and analysis of clinical studies involves several stakeholders with different professional backgrounds. Typically, principle investigators are familiar with standard office tools, data managers apply electronic data capture (EDC) systems and statisticians work with statistics software. Case report forms (CRFs) specify the data model of study subjects, evolve over time and consist of hundreds to thousands of data items per study. To avoid erroneous manual transformation work, a converting tool for different representations of study data models was designed. It can convert between office format, EDC and statistics format. In addition, it supports semantic annotations, which enable precise definitions for data items. A reference implementation is available as open source package ODMconverter at http://cran.r-project.org.

    2017-01-01

    This paper summarizes the results of a two-day dynamic monitoring of Michelangelo's David subject to environmental loads (city traffic and pedestrian loading induced by tourists visiting the Accademia Gallery). The monitoring was carried out by a no-contact technique using an interferometric radar, whose effectiveness in measuring the resonant frequencies of structures and historic monuments has proved over the last years through numerous monitoring activities. Owing to the dynamic behavior of the measurement system (radar and tripod), an accelerometer has been installed on the radar head to filter out the movement component of the measuring instrument from the measurement of the David's displacement. Measurements were carried out in the presence and absence of visitors, to assess their influence on the dynamic behavior of the statue. A numerical model of the statue was employed to evaluate the experimental results.

    2014-06-01

    Studies have focused on foraging ecology of cattle egrets (Bubulcus ibis) and their selection of ungulate host species. However, few studies have been conducted at intraspecific levels, such as the sex/age class of a specific ungulate. In this study, the foraging behavior and intraspecific host selection of cattle egrets associated with Père David's deer (Elaphurus davidianus) were investigated at the Dafeng National Nature Reserve, China in summer 2011 and 2012. Egret-deer pairing status was analyzed and intraspecific host selection index was calculated. Cattle egrets preferred to feed with female deer compared with male deer and fawns. In contrast to solitary birds, cattle egrets following a deer benefited from a relatively low vigilance output, high foraging success, low energy expenditure, and high total foraging yields. These egrets also maximized benefits when they followed female deer compared with male deer and fawns. Our results further indicated that egrets likely preferred females because of the appropriate moving speed that allowed these egrets to follow and forage sufficiently and effectively. The males of Père David's deer were possibly more aggressive than the females during the rutting season, causing egrets to experience difficulty in accompaniment and feeding. Fawns were not preferred because they were usually motionless and insufficiently large to stir more insects. We did not find any behavioral differences in vigilance and feeding between juveniles and adults. Our results suggested that cattle egrets could obtain significant benefits from their association with Père David's deer, and these benefits were maximized when they followed female deer.

  14. General health promotion in general dental practice--the involvement of the dental team Part 2: A qualitative and quantitative investigation of the views of practice principals in South Yorkshire.

    PubMed

    Dyer, T A; Robinson, P G

    2006-07-08

    To investigate the factors that might influence the provision of general health promotion through seven different health interventions by dental teams in general dental practice. A mixed-method was used comprising cross-sectional qualitative research using semi-structured interviews of a purposive sample of 10 practice principals, and a cross sectional survey of a practice principal from every dental practice in South Yorkshire, using a self-complete questionnaire. Two core categories emerged from the qualitative data: seeing health or disease and practitioners' views of the structure of dental practice. The former refers to the participants' general outlook and cut across many dimensions constituting the structure of dental practice. Health-orientated dentists were more likely to be involved in prevention and were more open-minded to expanding the dental team's role into general health promotion. However participants perceived that barriers existed to involvement such as time and financial factors, current workload and lack of personal skills. The response rate of useable questionnaires in the cross sectional survey was 84%. Reported levels of involvement in general health promotion were low. Most frequently reported barriers were 'insufficient funding' and 'poor use of time'. 'Poor use of time' and 'lack of training/knowledge' were reported less frequently for professionals complementary to dentistry (PCDs) than dentists (p<0.05). Most dentists agreed that PCDs could be trained to deliver health interventions and would be happy for PCDs to do so in their practice if reported barriers were removed. Although dental teams' involvement in general health promotion is low, there is willingness to increase involvement, particularly among health-orientated dentists. Some reported barriers to involvement might be removed by impending changes to the GDS in England. Other important factors include a lack of education and workforce shortages of dentists and PCDs.

    2016-01-01

    David Kasner, MD (1927–2001), used his extensive dissections of eye bank eyes and experiences in teaching cataract surgery to resident physicians to realize that excision of vitreous when present in the anterior chamber of eyes undergoing cataract surgery was preferable to prior intraoperative procedures. Noting that eyes tolerated his maneuvers, he then performed planned subtotal open-sky vitrectomies; first on a traumatized eye in 1961, then on two eyes of patients with amyloidosis (1966–1967). The success of these operations was noted by others, most particularly Robert Machemer, MD. Kasner’s work directly led to further surgical developments, including closed pars plana vitrectomy.

    2005-10-01

    A recurrent linear network can be trained with Oja's constrained Hebbian learning rule. As a result, the network learns to represent the temporal context associated to its input sequence. The operation performed by the network is a generalization of Principal Components Analysis (PCA) to time-series, called Recursive PCA. The representations learned by the network are adapted to the temporal statistics of the input. Moreover, sequences stored in the network may be retrieved explicitly, in the reverse order of presentation, thus providing a straight-forward neural implementation of a logical stack.

    Shortly after AGU launched its annual voluntary contribution campaign last year—the theme was “Building Tomorrow's Talent Today”—the Union's development office received an e-mail message from David E. Lumley about establishing a scholarship for a high-school student or undergraduate. Many scientific societies and associations have quite a few named scholarships, but for AGU this was a new concept. Lumley was sure of what he wanted to do and even more excited when he learned that his scholarship would be a first for AGU. “I want to help inspire today's young minds to work on problems of global importance in both the energy and environment sectors of industry and academia,” Lumley said. Recipients of the David E. Lumley Young Scientist Scholarship for Energy and Environmental Science will be expected to present a paper and to participate in various student activities at Fall Meeting. “Meeting some of the ‘giants’ of geoscience and getting their feedback on research is a big deal for these young students. We sometimes lose sight of this,” he said.

  10. David Duke, running for governor, proposes tattooing people with HIV.

    PubMed

    1995-05-19

    Former Ku Klux Klan leader, David Duke, planning a second run for governor of Louisiana, said he would curb the AIDS epidemic by tattooing people who are infected with HIV. His suggestion is to put indelible, glow-in-the-dark tattoos on the genitals of people infected with HIV. According to Duke, it may sound very draconian but it would not demean people. He also believes that tattooing would be legal because courts have a history of supporting the quarantining and institutionalizing of people with infectious diseases, such as tuberculosis. Duke said Cuba has had some success in using quarantines to reduce HIV infection, but he does not think it would work in the United States because it would cost too much. According to Duke, many people who get HIV from irresponsible behavior do not tell their partners that they have AIDS--these people are mad at the world and engage in dangerous behaviors even more.

    One of the objectives of the Coastal Data Network System established and maintained by the Coastal and Oceanographic Engineering Laboratory at the University of Florida is to acquire and document storm surge data along the Florida Coast. Since the establishment of the system only one major hurricane resulted in storm surge of significance. This was Hurricane David which swept through the lower part of Florida's east coast in September 1979. Storm surge data were obtained at Miami Beach, Palm Beach, and Vero Beach. These data were analyzed and documented. In addition, the numerical storm surge model developed by Dean and Chiu was used to compute the storm surges at Palm Beach and Vero Beach to facilitate comparisons.

  6. Principal stratification in causal inference.

    PubMed

    Frangakis, Constantine E; Rubin, Donald B

    2002-03-01

    Many scientific problems require that treatment comparisons be adjusted for posttreatment variables, but the estimands underlying standard methods are not causal effects. To address this deficiency, we propose a general framework for comparing treatments adjusting for posttreatment variables that yields principal effects based on principal stratification. Principal stratification with respect to a posttreatment variable is a cross-classification of subjects defined by the joint potential values of that posttreatment variable tinder each of the treatments being compared. Principal effects are causal effects within a principal stratum. The key property of principal strata is that they are not affected by treatment assignment and therefore can be used just as any pretreatment covariate. such as age category. As a result, the central property of our principal effects is that they are always causal effects and do not suffer from the complications of standard posttreatment-adjusted estimands. We discuss briefly that such principal causal effects are the link between three recent applications with adjustment for posttreatment variables: (i) treatment noncompliance, (ii) missing outcomes (dropout) following treatment noncompliance. and (iii) censoring by death. We then attack the problem of surrogate or biomarker endpoints, where we show, using principal causal effects, that all current definitions of surrogacy, even when perfectly true, do not generally have the desired interpretation as causal effects of treatment on outcome. We go on to forrmulate estimands based on principal stratification and principal causal effects and show their superiority.

    1993-01-01

    This is a brief summary of the science findings of the Magellan mission, principally based on data from the radar system. Future plans for Magellan include acquisition of high resolution gravity data from a nearly circular orbit and atmospheric drag and occultation experiments. The Magellan science results represent the combined effort of more than 100 Magellan investigators and their students and colleagues. More extensive discussions can be found in the August and October, 1992 issues of the Journal of Geophysical Research, Planets. The Magellan mission's scientific objectives were to provide a global characterization of landforms and tectonic features; to distinguish and understand impact processes; to define and explain erosion, deposition, and chemical processes; and to model the interior density distribution. All but the last objective, which requires new global gravity data, have been accomplished, or we have acquired the data that are required to accomplish them.

    Accuracy and precision of leaf positioning in multileaf collimators (MLCs) are significant factors for the accuracy of IMRT treatments. This study aimed to investigate the accuracy and repeatability of the MLC leaf positioning via the DAVID in vivo dosimetric system for dynamic and static MLC systems. The DAVID system was designed as multiwire transmission ionization chamber which is placed in accessory holder of linear accelerators. Each wire of DAVID system corresponds to a MLC leaf-pair to verify the leaf positioning accuracy during IMRT treatment and QA. In this study, verifications of IMRT plans of five head and neck (H&N) and five prostate patients treated in a Varian DHX linear accelerator with 80-leaf MLC were performed using DAVID system. Before DAVID-based dosimetry, Electronics Portal Imaging Device (EPID) and PTW 2D ARRAY dosimetry system were used for 2D verification of each plan. The measurements taken by DAVID system in the first day of the treatments were used as reference for the following measurements taken over the next four weeks. The deviations in leaf positioning were evaluated by "Total Deviation (TD)" parameter calculated by DAVID software. The delivered IMRT plans were originally prepared using dynamic MLC method. The same plans were subsequently calculated based on static MLC method with three different intensity levels of five (IL5), 10 (IL10) and 20 (IL20) in order to compare the performances of MLC leaf positioning repeatability for dynamic and static IMRT plans. The leaf positioning accuracy is also evaluated by analyzing DynaLog files based on error histograms and root mean square (RMS) errors of leaf pairs' positions. Moreover, a correlation analysis between simultaneously taken DAVID and EPID measurements and DynaLog file recordings was subsequently performed. In the analysis of DAVID outputs, the overall deviations of dynamic MLC-based IMRT calculated from the deviations of the four weeks were found as 0.55%±0.57% and 1.48%±0

    NASA Astrophysics Data System (ADS)

    Borucki, William J.

    2013-01-01

    Dave worked on scientific space instrumentation since the Apollo era in the mid-1960s. He was born and raised in Milwaukee, WI, and attended Milwaukee Lutheran High School where he built a Michelson interferometer that proved to be a stepping-stone for his interest in physics. Dave graduated from the University of Wisconsin-Madison, where he earned a Bachelor of Science in applied mathematics and engineering physics in 1967. As an undergraduate, he worked on balloon-launched sounding rockets and scientific instruments in X-ray and gamma-ray astronomy. At Cornell University, Dave earned a master's degree in 1971, and a doctorate in 1972, both in physics. He built a balloon-borne gamma-ray telescope that detected the first pulsed high-energy gamma rays from the Crab pulsar. In 1972, Dave began his career at American Science and Engineering where he was the project scientist for the Uhuru X-ray satellite. Later, he served as the project scientist for the development of the Einstein Observatory. Dave joined the Smithsonian Center for Astrophysics in 1977 as the project scientist for the Spacelab-2 infrared telescope. There, he served as a co-investigator on the Space Infrared Telescope Facility - IRAC camera proposal, and co-investigator on the Submillimeter Wave Astronomy Satellite, which launched in December 1998. Dave came to NASA Ames Research Center to lead the mission operations for SIRTF and SOFIA (Stratospheric Observatory for Infrared Astronomy) in 1988. He created the Flight Opportunities for Science Teacher EnRichment project. In 1992, Dave began working on what has become the Kepler mission, for which he served as deputy principal investigator until retiring in August 2011.

    2011-01-31

    The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC). This tract of land (hereinafter referred to as Screen Arts) is located in the Vestal Community in the 2000-block of Maryville Pike in south Knoxville, Tennessee, as shown in Figure A-1. This tract of land has been used primarily to store salvaged equipment and materials for resale, recycle, or for disposal in the former landfill once operated by DWI. The DWI Site industrial landfill and metal recycling business had been permitted by the Tennessee Division of Radiological Health to accept low-level radiologically contaminated metals. DWI received materials and equipment associated with operations from DOE sites, including those in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. It is likely that items stored at Screen Arts may have contained some residual radiological materials.

  18. David Malament and the Conventionality of Simultaneity: A Reply

    NASA Astrophysics Data System (ADS)

    Grünbaum, Adolf

    2010-10-01

    In 1977, David Malament proved the valuable technical result that the simultaneity relation of standard synchrony ɛ=1/2 with respect to an inertial observer O is uniquely definable in terms of the relation κ of causal connectibility. And he claimed that this definability undermines my own version of the conventionality of metrical simultaneity within an inertial frame. But Malament’s proof depends on the imposition of several supposedly “innocuous” constraints on any candidate for the simultaneity relation relative to O. Relying on Allen I. Janis’s 1983 challenge to one of these constraints, I argue that Malament’s technical result did not undermine my philosophical construal of the ontological status of relative metrical simultaneity. Furthermore, I show that (a) Michael Friedman’s peremptorily substantivalist critique of my conception, which Malament endorses, is ill-founded, and (b) if Malament had succeeded in discrediting my own conventionalist version of metrical simultaneity, he would likewise have invalidated Einstein’s pioneering version of it.

  19. David Hartley's psychobiological associationism and the legacy of Aristotle.

    PubMed

    Buckingham, H W; Finger, S

    1997-04-01

    The idea that there are certain "laws" of learning (similarity, contrast, contiguity) can be traced to Aristotle. He maintained that external stimuli cause small movements in the vessels to the dominant heart, the vestiges of which can be linked to one another. Aristotle's laws of learning were incorporated into the writings of Hobbes, Locke, and Berkeley, men who said nothing about the physiological correlates of mental associations. This left the door open for David Hartley to combine mental associationism with the Newtonian idea that sensations can cause minute particle vibrations in the nerves. Hartley's amalgam of psychology, philosophy, and neurology was first presented in 1746, as a "trial balloon" at the end a little-known monograph on a treatment for kidney stones. It was repeated three years later in his better-known Observations on Man. In many ways, modern psychobiological connectionism can be traced back to Hartley's Conjectures of 1746, in which Aristotle's original thoughts were modified with then current ideas about functions of the mind and the nervous system.

  20. David Florida Laboratory: Support for mobile satellite communications

    1995-01-01

    The comprehensive integration and environmental (including RF) test facilities of the Canadian Space Agency's David Florida Laboratory (CSA)(DFL) were used extensively for the MSAT Program. Following a description of the facilities, the paper outlines their application to the qualification of the two MSAT satellites following an overview of the test plan. Particular emphasis is given to passive intermodulation measurement (PIM) demands, which for the MSAT satellites, contributed to the need to extend the anechoic chamber. The extended chamber was also used for an EMC test and SAR signature test of the RADARSAT satellite. The DFL's facilities are being used for additional aspects of mobile satellite communications. One shielded anechoic Extra High Frequency (EHF) chamber and associated test equipment are employed predominantly for measuring the performance of the IRIDIUM satellites' Engineering Model Gateway Moveable Antennas (EM)(GMA). Other chambers are used for testing aeronautical antennas on behalf of Inmarsat. Still others combine thermal and PIM testing. The paper concludes with a review of the test requirements of evolving satcom missions such as Inmarsat Aero-1.

  1. Sir David Brewster's changing ideas on the plurality of worlds

    NASA Astrophysics Data System (ADS)

    de Asúa, Miguel

    2006-06-01

    In the course of his long life the Scottish physicist David Brewster wrote copiously about the plurality of worlds. More Worlds than One (1854), perhaps his strongest statement on the question, was written as an answer to William Whewell's On the Plurality of Worlds (1853), which argued that life was a privilege of the Earth. Brewster's ideas changed drastically along the years in many crucial issues such as the habitability of the Sun and the Moon, the possibility that extraterrestrials could be different from humans, and the occupation of the Earth by intelligent races in the distant past. This paper succinctly surveys Brewster's main lines of thought about the plurality of worlds underlining the significance of his first two articles devoted exclusively to this topic. They were published in 1838 in The Monthly Chronicle, and affirm the habitability of the planets while denying that of the Moon. As is the case with many Victorian scientists, belief in pluralism was for Brewster part and parcel of a complex of ideas and attitudes in which it is hard to distinguish science from religion. I shall argue that a fair number of the shifting opinions and inconsistencies detectable in Brewster's ideas on the plurality of worlds can be attributed to the fact that these were used as pliable apologetic instruments in his scientific writings, many of which are permeated by strong religious concerns.

    The database for annotation, visualization and integrated discovery (DAVID), which can be freely accessed at http://david.abcc.ncifcrf.gov/, is a web-based online bioinformatics resource that aims to provide tools for the functional interpretation of large lists of genes/proteins. It has been used by researchers from more than 5000 institutes worldwide, with a daily submission rate of ∼1200 gene lists from ∼400 unique researchers, and has been cited by more than 6000 scientific publications. However, the current web interface does not support programmatic access to DAVID, and the uniform resource locator (URL)-based application programming interface (API) has a limit on URL size and is stateless in nature as it uses URL request and response messages to communicate with the server, without keeping any state-related details. DAVID-WS (web service) has been developed to automate user tasks by providing stateful web services to access DAVID programmatically without the need for human interactions. The web service and sample clients (written in Java, Perl, Python and Matlab) are made freely available under the DAVID License at http://david.abcc.ncifcrf.gov/content.jsp?file=WS.html.

  10. Analysis of principal nested spheres.

    Jung, Sungkyu; Dryden, Ian L; Marron, J S

    2012-09-01

    A general framework for a novel non-geodesic decomposition of high-dimensional spheres or high-dimensional shape spaces for planar landmarks is discussed. The decomposition, principal nested spheres, leads to a sequence of submanifolds with decreasing intrinsic dimensions, which can be interpreted as an analogue of principal component analysis. In a number of real datasets, an apparent one-dimensional mode of variation curving through more than one geodesic component is captured in the one-dimensional component of principal nested spheres. While analysis of principal nested spheres provides an intuitive and flexible decomposition of the high-dimensional sphere, an interesting special case of the analysis results in finding principal geodesics, similar to those from previous approaches to manifold principal component analysis. An adaptation of our method to Kendall's shape space is discussed, and a computational algorithm for fitting principal nested spheres is proposed. The result provides a coordinate system to visualize the data structure and an intuitive summary of principal modes of variation, as exemplified by several datasets.
