  3. Understanding Transactional Memory (Extended Abstract)

    NASA Astrophysics Data System (ADS)

    Lourenço, João

    Transactional Memory [3] (TM) is a new paradigm for concurrency control that brings the concept of transactions, widely known from the Databases community, into the management of data located in main memory. TM delivers a powerful semantics for constraining concurrency and provides the means for the extensive use of the available parallel hardware. TM uses abstractions that promise to ease the development of scalable parallel applications by achieving performances close to fine-grained locking while maintaining the simplicity of coarse-grained locking.

    The first Subwog 12-D Tritium Technology Meeting was held at the Westinghouse Savannah River Site during the week of May 21, 1990. Subwog 12-D was created as a subwog of JOWOG 12 to address the need to understand tritium applications throughout the entire weapons complex. This includes weapons related concerns, but is primarily intended to cover tritium production and handling, environmental, safety and health issues, compatibility with materials in general; and facility design, commissioning and decommissioning activities. Tritium technology issues discussed included the physical and chemical properties, kinetics, storage, reservoir loading techniques, isotope exchange, radiolysis/aging, process and handling technology, compatibility, purification and filtering, analysis, monitoring methods, function testing, packaging and shipping, environmental and operational safety, facility design and safety, glovebox atmosphere clean-up systems, glovebox/facility decommissioning, tritium production target materials, and tritium recovery. This document provides a collection of most of the unclassified extended abstracts and abstracts presented at Subwog 12-D.

    When the 4 August deadline for submitting Fall Meeting abstracts passed, AGU had received more than 20,000 abstracts, a record-breaking number. The submission process had an unexpected by-product: It inspired some scientists to write haiku on Twitter. (Haiku is a form of Japanese poetry typically having three lines, the first with five syllables, the second with seven, and the third with five.) The following are examples of the haiku tweets, with the hashtag #AGU11AbstractHaiku. (For those who want to keep updated about the Fall Meeting on Twitter, the hashtag is #AGU11.)

  8. Masking failures of multidimensional sensors (extended abstract)

    NASA Technical Reports Server (NTRS)

    Chew, Paul; Marzullo, Keith

    1990-01-01

    When a computer monitors a physical process, the computer uses sensors to determine the values of the physical variables that represent the state of the process. A sensor can sometimes fail, however, and in the worst case report a value completely unrelated to the true physical value. The work described is motivated by a methodology for transforming a process control program that can not tolerate sensor failure into one that can. In this methodology, a reliable abstract sensor is created by combining information from several real sensors that measure the same physical value. To be useful, an abstract sensor must deliver reasonably accurate information at reasonable computational cost. Sensors are considered that deliver multidimensional values (e.g., location or velocity in three dimensions, or both temperature and pressure). Geometric techniques are used to derive upper bounds on abstract sensor accuracy and to develop efficient algorithms for implementing abstract sensors.

  11. Discrepancies between proceedings abstracts and posters at a scientific meeting.

    Zelle, Boris A; Zlowodzki, Michael; Bhandari, Mohit

    2005-06-01

    The proceedings handbook of abstracts from scientific meetings aims to provide meeting attendees with an accurate summary of scientific presentations. Given that posters are prepared closer to the meeting than the abstracts for the proceedings book, we hypothesized that there is a high rate of inconsistency between abstracts in the proceedings handbook and the corresponding posters. We compared the poster abstracts printed in the proceedings handbook with the actual posters at the 71st annual meeting of the American Academy of Orthopaedic Surgeons in 2004. Our comparison included all 50 trauma posters and 52 adult reconstruction knee posters. This comparison revealed discrepancies in 76% of the presented posters. These changes were detected in all parts of the posters including titles (33%), authorship (49%), methods (8%), results (30%), and conclusions (2%). The sample size changed in 15% of the studies. Discrepancies between the trauma posters versus the adult reconstruction knee posters were similar. Our findings suggest that discrepancies between the poster abstracts in the proceedings handbook and actual poster presentations are common, but changes in conclusions are rare. Meeting attendees should not assume that the proceedings handbook provides an accurate reflection of poster presentations. Visiting the poster section is recommended.

  12. Writing Abstracts and Developing Posters for National Meetings

    2011-01-01

    Abstract Presenting posters at national meetings can help fellows and junior faculty members develop a national reputation. They often lead to interesting and fruitful networking and collaboration opportunities. They also help with promotion in academic medicine and can reveal new job opportunities. Practically, presenting posters can help justify funding to attend a meeting. Finally, this process can be invaluable in assisting with manuscript preparation. This article provides suggestions and words of wisdom for palliative care fellows and junior faculty members wanting to present a poster at a national meeting describing a case study or original research. It outlines how to pick a topic, decide on collaborators, and choose a meeting for the submission. It also describes how to write the abstract using examples that present a general format as well as writing tips for each section. It then describes how to prepare the poster and do the presentation. Sample poster formats are provided as are talking points to help the reader productively interact with those that visit the poster. Finally, tips are given regarding what to do after the meeting. The article seeks to not only describe the basic steps of this entire process, but also to highlight the hidden curriculum behind the successful abstracts and posters. These tricks of the trade can help the submission stand out and will make sure the reader gets the most out of the hard work that goes into a poster presentation at a national meeting. PMID:21241194

    and allows ample time for informal group discussions and poster presentations. The intent of this format is to foster informal discussion of research among PIs and ERSD program managers-discussion that is a hallmark of previous ERSD-sponsored meetings. Morning sessions will be dominated by oral presentations from PIs chosen by ERSD program managers to communicate key topics of research within the program. There is ample time during lunch and in the early afternoon for small group discussions/meetings prior to convening again in the later afternoon for oral presentations on field research conducted at the Integrated Field-Scale Subsurface Research Challenge sites (IFCs). Formal poster sessions begin after dinner. Abstracts for all poster presentations are listed within this meeting booklet. On behalf of the ERSD program managers and staff, we thank you for attending this year's PI meeting. We look forward to discussing the results of your research with you and your ideas for the future, and we hope that this meeting will continue as an important tradition for PIs in the program and serve as a valuable resource for your investigations.

  17. 4th Annual DOE-ERSP PI Meeting: Abstracts

    SciTech Connect

    Hazen, Terry C.

    2009-03-01

    This contains abstracts from the 2009 Annual Environmental Remediation Sciences Program (ERSP) Principal Investigators (PI) Meeting. The ERSP seeks to advance fundamental science to understand, predict, and mitigate the impacts of environmental contamination from past nuclear weapons production and provide a scientific basis for the long-term stewardship of nuclear waste disposal. These ambitious goals cannot be achieved by any one project alone. Therefore, ERSP funds a combination of research programs at the DOE national laboratories, individual projects at universities and federal agencies, and large long(er)-term field site research. Integration of these activities to advance the ERSP goals is a constant challenge, but made significantly simpler by bringing together all funded ERSP researchers once a year to discuss the very latest research results. It is at these meetings where new ideas and/or scientific advancements in support of ERSP goals can be discussed and openly debated among all PIs in the program. The ERSP thrives, in part, on the new ideas, concepts, scientific connections, and collaborations generated as a result of these meetings. The annual PI Meeting is very much a working meeting with three major goals: (1) to provide opportunities for scientific interaction among the ERSP scientists, a critical element for the program; (2) to provide the ERSP program staff with an opportunity to evaluate the progress of each program and project; and (3) to showcase the ERSP to interested parties within DOE and within other federal agencies In addition to program managers from within OBER, there will be representatives from other offices within DOE and other federal agencies in attandance at the meeting.

    2016-01-01

    The UK Extracellular Vesicles (UKEV) Forum meetings were born of the realization that there were a number of UK laboratories studying extracellular vesicle biology and using similar techniques but without a regular national meeting dedicated to EVs at which to share their findings. This was compounded by the fact that many of these labs were working in different fields and thus networking and sharing of ideas and best practice was sometimes difficult. The first workshop was organized in 2013 by Dr Charlotte Lawson, under the auspices of the Society for Endocrinology, led to the founding of the UKEV Forum and the organization of a British Heart Foundation sponsored 1-day conference held in London in December 2014. Although growing in size every year, the central aims of these workshops have remained the same: to provide a forum for discussion and exchange of ideas, to allow young scientists to present their data in the form of short talks and poster presentations and to discuss their work with more established scientists in the field. Here we include the presented abstracts for the 2015 1-day conference hosted by Cardiff University. This meeting was attended by approximately 130 delegates throughout the United Kingdom, but also attended by delegates from Belgium, Netherlands, France, Ireland and other nations. The day composed of plenary presentations from Prof Matthias Belting, Lund University, Sweden and Dr Guillaume van Niel, Institut Curie, Paris together with 10 short presentations from submitted abstracts. The topics covered were broad, with sessions on Mechanisms of EV production, EVs in Infection, EVs in Cancer and in Blood and Characterizing EVs in Biological fluids. This hopefully gives a reflection of the range of EV-related studies being conducted currently in the UK. There were also 33 poster presentations equally broad in subject matter. The organizers are grateful to the Life Science Research Network Wales – a Welsh government-funding scheme that

    Methods for automatically constructing concrete executable programs from an abstract prototype program by applying transformations based on theorems of matrix algebra and on algebraic properties of programming languages are described. These methods provide a user with highly efficient programs tailored to his environment while maintaining the advantages of high reliability and low cost associated with routines from the best mathematical software libraries. Also, the transformations which produce such programs represent a formal codification of rules for writing linear algebra programs.

  20. More insight into the fate of biomedical meeting abstracts: a systematic review

    PubMed Central

    von Elm, Erik; Costanza, Michael C; Walder, Bernhard; Tramèr, Martin R

    2003-01-01

    Background It has been estimated that about 45% of abstracts that are accepted for presentation at biomedical meetings will subsequently be published in full. The acceptance of abstracts at meetings and their fate after initial rejection are less well understood. We set out to estimate the proportion of abstracts submitted to meetings that are eventually published as full reports, and to explore factors that are associated with meeting acceptance and successful publication. Methods Studies analysing acceptance of abstracts at biomedical meetings or their subsequent full publication were searched in MEDLINE, OLDMEDLINE, EMBASE, Cochrane Library, CINAHL, BIOSIS, Science Citation Index Expanded, and by hand searching of bibliographies and proceedings. We estimated rates of abstract acceptance and of subsequent full publication, and identified abstract and meeting characteristics associated with acceptance and publication, using logistic regression analysis, survival-type analysis, and meta-analysis. Results Analysed meetings were held between 1957 and 1999. Of 14945 abstracts that were submitted to 43 meetings, 46% were accepted. The rate of full publication was studied with 19123 abstracts that were presented at 234 meetings. Using survival-type analysis, we estimated that 27% were published after two, 41% after four, and 44% after six years. Of 2412 abstracts that were rejected at 24 meetings, 27% were published despite rejection. Factors associated with both abstract acceptance and subsequent publication were basic science and positive study outcome. Large meetings and those held outside the US were more likely to accept abstracts. Abstracts were more likely to be published subsequently if presented either orally, at small meetings, or at a US meeting. Abstract acceptance itself was strongly associated with full publication. Conclusions About one third of abstracts submitted to biomedical meetings were published as full reports. Acceptance at meetings and

    Scientific research originating from Brazil appears to be rising in several medical fields. Research results are often presented at scientific meetings before publication in peer-reviewed journals. We investigated the publication rate of Brazilian studies presented in American Urological Association (AUA) meetings and compared with the rate of publication of Brazilian oncological studies presented at the American Society of Clinical Oncology (ASCO) meetings. a hand search of 12,454 abstracts presented at aua meetings 2001-2007 was conducted. abstracts for which at least two-thirds of institutions were from brazil were considered as brazilian. final publication was searched in pubmed and lilacs databases. oncological abstracts were also hand searched in the asco meetings proceedings in the same years. There was no significant temporal trend in the proportion of AUA studies originating from Brazil along those 7 years. A total of 195 abstracts (1.57%) were from Brazil. One hundred (51.3%) abstracts were published in full, and the estimated 5-year publication rate was 48.2%. There was a progressive increase in publication rates for studies categorized as video, poster, and podium presentations. Considering abstracts presented in years 2001-2005, urologic publication rate was significantly higher than for abstracts presented at the ASCO meeting. Our results suggest that the Brazilian contribution to AUA meetings is at a plateau and that the Brazilian literature contribution is greater in urology than in oncology. Efforts must be invested towards raising this plateau and understanding qualitative aspects of the urology scientific output from Brazil.

    2016-10-20

    IntroductionEvery two years, scientists, natural resource managers, outreach specialists, and a variety of other interested parties get together for the biennial meeting of the Yellowstone Volcano Observatory (YVO). Each time, the theme varies. In past years, we have focused the meeting around topics including monitoring plans, emergency response, geodesy, and outreach. This year, we spent the first half-day devoted to recent research results, plans for upcoming studies, and geothermal monitoring. On the second day, our focus switched to eruption precursors, particularly as they apply to large caldera systems.Very few large explosive eruptions from caldera systems have taken place in recorded history. Therefore, there are few empirical data with which to characterize the nature of volcanic unrest that might precede eruptions with volcano explosivity index (VEI) of six or greater. For this reason, we set up a series of talks that explore what we know and don’t know about large eruptions. We performed an informal expert elicitation (a frequently used method to characterize expert opinion) with a small number of our colleagues, which served as the basis for a productive discussion session.This short volume of abstracts and extended abstracts provides a summary of the presentations made at the YVO meeting held in Mammoth Hot Springs, Wyoming, on May 10–11, 2016.

    Compositional verification techniques in the assume- guarantee style have been successfully applied to transition systems to efficiently reduce the search space by leveraging the compositional nature of the systems under consideration. We adapt these techniques to the domain of hybrid systems with affine dynamics. To build assumptions we introduce an abstraction based on location merging. We integrate the assume-guarantee style analysis with automatic abstraction refinement. We have implemented our approach in the symbolic hybrid model checker SpaceEx. The evaluation shows its practical potential. To the best of our knowledge, this is the first work combining assume-guarantee reasoning with automatic abstraction-refinement in the context of hybrid automata.

    Background: Abstract presentations at professional meetings provide a medium for disseminating the findings of scholarly activity. Rates of abstract publication from various biomedical disciplines have been evaluated, with pharmacy noted to be lower than other specialties. Previous research on pharmacy abstract publication rates was conducted for a limited number of professional meetings but has not been assessed using Google Scholar. Objective: To determine the full publication rate of abstracts presented at the 2005 American College of Clinical Pharmacy (ACCP) Spring and Annual Meetings, American Pharmacists Association (APhA) Annual Meeting, and American Society of Health-System Pharmacists (ASHP) Summer and Midyear Clinical Meetings. Methods: Publication status was assessed for abstracts presented during the 2005 ACCP Spring and Annual Meetings, APhA Annual Meeting, and ASHP Summer and Midyear Clinical Meetings using PubMed and Google Scholar. Data collected included abstract category, study category, practice site, database(s) in which publication appeared, time in months to publication, publication type, and journal of publication. Results: Evaluation of 2,000 abstracts presented in 2005 revealed an overall full publication rate of 19.8% (n = 384). Nearly all pharmacy abstracts were published as manuscripts (98.4%; n=378) and indexed in PubMed and Google Scholar (91.9%; n = 353), although a significant percentage were indexed in Google Scholar only (7.8%; n = 30). The mean time to full publication was 16.8 months (SD ±11.9 months). Conclusions: Results were consistent with previously reported full publication rates of abstracts from pharmacy association meetings, indicating that abstracts presented at pharmacy meetings continue to have a lower full publication rate than other health disciplines.

    A recent study examined the rate of full-length research paper publication following abstract presentation at the British association of clinical anatomists (BACA) annual meetings. The accepted standard for research dissemination is peer-reviewed publication following presentation at a national or international meeting. The study objectives were quantitative assessment of the abstracts presented at the American Association of Clinical Anatomists' (AACA) annual meetings with regards to the rate of subsequent full-length publication and comparison to BACA publication rates. All abstracts presented at the AACA annual meetings between 2003 and 2010 were analysed. MEDLINE was searched to identify peer-reviewed publications arising from each presented abstract. In total, 1,120 abstracts were presented with 22.9% (n = 257) subsequently published as full-length research papers. The mean number of abstracts presented each year was 140.0 ± 35.9. The median time to publication was 16 months. Chi-squared analysis showed the publication rate of abstracts presented at AACA (22.9%) was not statistically significantly different to BACA (20.4%) (P = 0.09). A total of 11.3% (n = 29) of the articles were published as full-length research articles before presentation as an abstract at an AACA meeting compared to 5.4% of abstracts presented at a BACA meeting. These rates are lower but comparable to those of surgical specialty meetings. Further work should try to identify any concerning reasons for the reduced rate of abstract publication in anatomical research. Clin.

    Purpose The acceptance rate for journal publication of the abstracts presented at the annual Korean Urological Association (KUA) meeting, the time to publication, and the effect of abstract characteristics on the publication pattern were analyzed and compared with data for abstracts from other major urological meetings. Materials and Methods A total of 1,005 abstracts listed in the abstract books of the 2006 (58th) and 2007 (59th) annual KUA meetings were analyzed, and their subsequent publication as listed in PubMed or KoreaMed between August 2006 and August 2011 was evaluated. Results A total of 41.59% of abstracts were published as full-length reports. Abstracts on sexual dysfunction, neurourology, prostate cancer, basic research, and benign prostatic hyperplasia showed the highest publication rates (54%, 52.27%, 48%, 47.56%, and 45%, respectively). It took 19.01±12.83 months on average for abstracts to be published in a journal, whereas it took 25.24±14.64 months and 17.51±11.89 months for publication in foreign and Korean journals, respectively (p<0.001). Conclusions Approximately 40% of studies presented as abstracts at the KUA meeting are subsequently published as full-length articles. The KJU is the most targeted journal. The mean time to publication is 1.5 years, and publication seems to be influenced by the study subject. PMID:22536473

    Dissemination of research is an integral part of the scientific process. Failure to disseminate research limits the scope for critical appraisal and potentially wastes valuable resources. The gold standard for dissemination of research is peer-reviewed publication following presentation at a national meeting. The primary objective of this study was quantitative assessment of the abstracts presented at British Association of Clinical Anatomists (BACA) summer and winter meetings with regards to the rates of subsequent publication and comparison to other medical specialties. Published abstracts from the summer and winter meetings of BACA between the years of 2000 and 2014 were analyzed. MEDLINE was searched to identify peer-reviewed publications arising from each presented abstract. In total, 1,807 abstracts were presented between the years of 2000 and 2014. The mean number of abstracts presented each year was 60.2, (range 26-157). In total, 20.4% of abstracts were subsequently published in MEDLINE-indexed journals with a median publication time of 19 months. The mean number of cadaveric prosections was 45.2 ± 78.8, (range 1-960). Analysis of abstracts focusing on radiographic imaging found the mean number of scans was 224.4 ± 807.1, (range 1-6,439). Biannual meetings of BACA are a forum for the presentation of high-quality anatomical research. BACA meeting abstracts have generally reduced publication rates compared to some surgical specialty meetings; however, there is no analysis available for an equivalent anatomical meeting. Further work should try to identify reasons that may hinder or limit subsequent publication of the anatomy abstracts presented at BACA. Clin.

    Each year medical students in Louisiana and residents from the eight Internal Medicine training programs in Louisiana are invited to submit abstracts for the Annual Louisiana American College of Physicians (ACP) Associates Meeting. The content of these abstracts includes clinical case vignettes or research activities. The abstracts have all identifying features removed (i.e., names, institutional affiliations, etc.) before being sent to physician judges. Each judge scores each abstract independently and then the scores from all judges are averaged and ranked. This year we are excited to be able to publish most highly ranked abstracts presented at this year's competition. These abstracts (17 oral; 14 poster) were presented at the Associates Meeting held at LSU Health Sciences Center in Baton Rouge on January 19, 2016. We would like to thank the Journal of the Louisiana State Medical Society and appreciate its efforts to publicize the hard work of these trainees.

    The purpose of this article is to articulate how the Roy adaptation model has been extended as a conceptual framework to meet changing global needs. Nursing's social mandate is described within the significant global changes of this century. The required synthesis of the individual and common good is predicated within the thinking of the model. Changes are described with specific examples of groups from the family to global society levels. The implications of this work for knowledge development are identified.

  18. Extending Automatic Parallelization to Optimize High-Level Abstractions for Multicore

    Automatic introduction of OpenMP for sequential applications has attracted significant attention recently because of the proliferation of multicore processors and the simplicity of using OpenMP to express parallelism for shared-memory systems. However, most previous research has only focused on C and Fortran applications operating on primitive data types. C++ applications using high-level abstractions, such as STL containers and complex user-defined types, are largely ignored due to the lack of research compilers that are readily able to recognize high-level object-oriented abstractions and leverage their associated semantics. In this paper, we automatically parallelize C++ applications using ROSE, a multiple-language source-to-source compiler infrastructure which preserves the high-level abstractions and gives us access to their semantics. Several representative parallelization candidate kernels are used to explore semantic-aware parallelization strategies for high-level abstractions, combined with extended compiler analyses. Those kernels include an array-base computation loop, a loop with task-level parallelism, and a domain-specific tree traversal. Our work extends the applicability of automatic parallelization to modern applications using high-level abstractions and exposes more opportunities to take advantage of multicore processors.

    Research abstracts presented during the proceedings of an annual meeting are often cited and can influence clinical practice. Prior studies show that roughly 50% of abstracts at American Society for Surgery of the Hand meetings are eventually published. Yet, it is unknown how often the results or conclusions of published studies differ from the podium presentation. The objective of this study was to quantify the differences between abstracts presented during the annual meeting of the American Society for Surgery of the Hand and the resulting manuscripts. We retrospectively reviewed every abstract delivered as a podium presentation at the American Society for Surgery of the Hand annual meeting from 2000 to 2010. We searched the PubMed database for matching publications and compared authorship, country of origin, hypothesis, study design and methodology, changes in study groups or populations, results, and conclusions. Of 798 total abstracts, we analyzed 719 involving the hand, wrist, and brachial plexus. Fifty-six different journals published 393 of the abstracts, for a 49% publication rate. Mean time to publication was 18 months with a median of 14 and maximum of 122 months. There were inconsistencies between the results and/or conclusions in 14% of full-length articles compared with the abstract presented at the meeting. A total of 9% of articles were published with fewer subjects. Authorships changes were noted in 54% of publications. Abstracts represent preliminary investigations and major and minor changes occur before subsequent publication. Caution should be exercised in referencing abstracts or altering clinical practice based on their content. Economic/decision analysis IV. Copyright © 2014 American Society for Surgery of the Hand.

    OBJECTIVE: To determine the publication rate of orally-presented abstracts from the 2003 Urological Brazilian Meeting, as well as the factors determining this publication rate. MATERIALS AND METHODS: The publication rate of the 313 orally-presented abstracts at the 2003 Urological Brazilian Meeting was evaluated by scanning the Lilacs, Scielo and Medline databases. The time between presentation and publication, the state and country of the abstract, the research methodology (cross-sectional, case-control, retrospective case series, prospective case series or clinical trial), whether drugs were utilized and the topic of the study were all characterized. RESULTS: Thirty-nine percent of the abstracts were published after a median time of 14 months (range: 1 to 51 months). There were high publication rates for cross-sectional abstracts (75%), drug utilization studies (51.3%), clinical trials (50%) and prospective case series’ (48.1%). However, there was only a moderate statistical trend towards a higher publication rate in the prospective case series (p=0.07), while the retrospective case series’ showed statistically lower publication rates than the other groups (33.7%, p=0.04). Abstracts on laparoscopic surgery had the highest publication rate (61.9%, p=0.03) compared to others topics. In 57% of the unpublished abstracts, there was no interest in or attempt to publish, and rejection was responsible for the lack of publication of only 4% of the abstracts. CONCLUSION: The publication rate of the orally-presented abstracts from the 2003 Urological Brazilian Meeting was comparable to that of international congresses. The subsequent publication of presented abstracts and the selection of prospective studies with stronger evidence should be encouraged and may improve the scientific quality of the meeting.

    To determine the percentage of abstracts presented at the Canadian Association of Radiologists (CAR) annual scientific meetings that go on to publication. Records of previous CAR meetings from the years 2005-2011 were obtained. An Internet search was performed to determine which abstracts went on to publication. Abstracts were assessed according to exhibit category (Resident Award Papers), educational institution, publishing journal, and time to publication. Of the 402 abstracts presented, 112 (28%) were published. Overall, an average of 37% of Radiologists-In-Training Presentations, 34% of Scientific Exhibits, and 20% of Educational Exhibits went on to publication. The University of British Columbia and University of Ottawa published the largest number of abstracts (66 and 62, respectively) from the years 2005-2011. The University of Montreal had the largest percentage of abstracts published (42%). The range of publishing journals was wide, but the top publisher was the Canadian Association of Radiologists Journal (27%). Eighty-three percent of abstracts were published within 3 years of being presented. In total, 28% of all the abstracts presented at the CAR conferences between 2005 and 2011 were published. Further exploration into the reasons and barriers for abstracts not being published may be a next step in future research. Copyright © 2015 Canadian Association of Radiologists.

    The present study aims to identify (1) what proportion of abstracts of clinical trials presented at The American Society for Laser Medicine and Surgery (ASLMS) annual meetings are published as full reports, (2) time to publication, and (3) factors that may predict the publication of research in peer-reviewed journals. Two investigators independently hand-searched all abstracts of the ASLMS meetings to identify all reports of clinical trials. Details of sample size, the country of origin, topic of research, type of presentation, type of laser, direction of outcome, and statistical significance were recorded for each abstract. To determine the full publication status of each study, The Cochrane Central Register of Controlled Trials, PubMed, and EMBASE was searched. A total of 198 abstracts were identified. Of these, 87 abstracts (44%) have been fully published. The average time from presentation at the meeting to full publication was 57 months (95% confidence interval = 52-61), and the estimated rate of abstracts published at 1, 2, and 4 years was 15, 30, and 38%, respectively. There is significant tendency for being fully published in high-power laser studies, with USA as country of origin, and orally presented. Our findings supports this opinion that conference abstracts can be an important source for systematic reviews and failure to identify trials presented in congresses might threaten the validity of systematic reviews.

    We set out to determine the rate, time-trend, and defining factors associated with publication of abstracts presented at two annual scientific meetings of the Canadian Association of Radiation Oncology (caro). All abstracts accepted for oral presentation in 2007 and 2010 were obtained from the caro program archives and searched using the PubMed database. Variables in the dataset included the year of presentation at caro and of publication in a scientific journal, time to publication (in months), publishing journal, impact factor of publishing journal, abstract research type (clinical, technical, or basic science) and disease site, country of origin, and university of the first author. Overall, 88 of 172 abstracts from the 2007 (n = 102) and 2010 (n = 70) caro meetings were published in peer-reviewed journals (publication rate: 51.2%). Mean time to publication was 18.5 months. Among research types, clinical research (62.5%) and, among disease sites, prostate cancer (40.4%) were most likely to be published. Of all the abstracts, 50.1% were contributed by only 2 universities, a proportion that resembles the overall abstract publication rate of 51.2%. The conversion rate for those 2 universities (51.1%) is very similar to that for all abstracts presented at the two meetings. Half the abstracts presented at the 2007 and 2010 caro meetings were ultimately published in journals indexed in PubMed by about 1.5 years after presentation. Half the abstracts and publications came from just 2 universities; more must to be done to close the gap.

    Pediatric critical care medicine abstracts presented at North American national academic meetings have not been followed up to determine their publication outcomes. Our objective was to determine the following: 1) the proportion of these presentations that are published in peer-reviewed journals within 5 years; 2) the impact of trainee status on time to and success of publication; and 3) the quality of the research as reflected in the publishing journal's impact factor. Four years of abstracts (2007-2011) were reviewed from the American Academy of Pediatrics, Pediatric Academic Societies, and Society of Critical Care Medicine national meetings. Pediatric critical care medicine abstracts were delineated by the meeting or identified by keyword search. Data included mode of presentation, trainee status of first author, publication status within 5 years based on a PubMed search, trainee position in the journal of publication authorship list, and the impact factor of journal of publication. We evaluated 267 pediatric critical care medicine abstracts, 85-94 from each meeting. Overall, 41% were published, with the highest rate in Pediatric Academic Societies abstracts (54% Pediatric Academic Societies, 38% Society of Critical Care Medicine, and 33% American Academy of Pediatrics; p = 0.011). Mean time to publication was 22 (± 3) months and did not differ by conference or presentation mode. Journal first authorship was retained in 84%. Journal impact factor was highest in Society of Critical Care Medicine abstracts (3.38 Society of Critical Care Medicine, 2.64 Pediatric Academic Societies, and 1.92 American Academy of Pediatrics; p = 0.006). First author trainee status was not associated with publication rate, time to publication, and impact factor. A total of 100% of trainees but only 79% of nontrainees who published retained first authorship. Less than half of pediatric critical care medicine research abstracts presented at North American national academic meetings

    To examine abstracts presented at the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Annual Meeting and to identify factors associated with publication success. All abstracts published in the August 1999 official program issue of the AAO-HNS Journal were examined. MEDLINE searches were performed to assess publication success. Multivariate analysis was performed to identify factors related to successful publication. We identified 473 abstracts, of which 260 (55%) were poster presentations. Median publication time was 16 months, with a publication rate of 50%. Multivariate analysis revealed oral presentation, statistical analysis, and number of authors to be the most significant predictive factors of publication success (odds ratios of 2.2, 1.9, and 1.2 respectively). Level of evidence did not correlate with publication success, even when case reports (n = 70) were excluded from the analysis. Publication rates in other disciplines ranged from 25% to 68%, with a mean of 47%. The rate of publication from the AAO-HNS Annual Meeting is similar to other disciplines. Oral presentations with inferential statistics in the abstract were most likely to be published. Conversely, level of evidence and direction of study inquiry were not significant predictors, suggesting that research design is a less important determinant of publication success. Our investigation is one of the first to critically analyze the factors in presentations at annual meetings that predict successful publication.

    Many abstracts presented at scientific meetings are never published as articles in peer-reviewed journals. Using PubMed search and custom computer programs, we retrospectively reviewed all 4824 abstracts presented at the United States and Canadian Academy of Pathology annual meetings from 2005 to 2007, and found an overall publication rate of 36% for a 3-year maximal follow-up. This rate is comparable with that of other medical societies with published data. The publication rate varied from 10 to 62% among different subspecialties. The format of presentation, either platform or poster, was also a significant predictor of outcome, with 42-50% publication rate for platform abstracts and 32-36% for poster abstracts. Country of origin and the use of statistical methods did not seem to affect outcome significantly. The average time from abstract submission to article publication was 18 months. Seven journals accounted for over half of all publications, and the top three journals were American Journal of Surgical Pathology (16.2%), Modern Pathology (9.1%), and American Journal of Clinical Pathology (8.3%).

    The Society for Obstetric Anesthesia and Perinatology (SOAP) annual meeting provides a forum to present new scientific work with the goal of broader dissemination of knowledge. The objective of this study was to evaluate the proportion of research abstracts presented at SOAP meetings, from 2010 to 2014, which resulted in peer-reviewed publications. The abstract-to-publication rate was compared with the percent of abstracts presented at biomedical meetings resulting in publication, as estimated by a 2007 Cochrane Review. The SOAP abstract-to-publication rate was lower than that of the Cochrane Review (26.8% vs 44.5%, P < .0001). Future work should identify barriers to publication.

    Not all research presented at scientific meetings is subsequently published and, even when it is, there may be inconsistencies between these results and what is ultimately printed. Although late-breaking trials sessions are now integrated into several major scientific meetings and the results are often promptly and prominently communicated, no studies have examined the publication fate and degree of consistency between meeting abstracts or presentations and subsequent full-length article publications for randomized controlled trials (RCTs) presented at these sessions. To compare RCT abstracts presented in the late-breaking trials session vs other sessions at a major scientific meeting and subsequent full-length publications. RCTs were identified by hand searching abstract proceedings booklets and related Web sites for the American College of Cardiology scientific meetings (1999-2002). Subsequent full-length articles were identified via electronic databases. Publication fate and degree of consistency between meeting abstract results and subsequent full-length publication results. The 86 late-breaking RCTs were significantly larger (median, 2737 patients vs 896; P<.001), were more likely to be preceded by a published design paper (27 [31%] vs 13 [13%]; P = .002), had higher quality scores when eventually published (mean Jadad score 2.69 vs 2.19; P = .01), and were less likely to report favorable results for the intervention than the 100 randomly chosen comparison RCTs presented in other sessions (50 [58%] vs 75 [75%]; P = .01; odds ratio 0.46; 95% confidence interval, 0.24-0.90). RCTs presented at the late-breaking trials sessions were significantly more likely to be published (79 [92%] vs 69 [69%]; P<.001) and appeared earlier after presentation (median 11.5 months vs 22.0 months; P<.001) than RCTs presented in other sessions, an association that persisted even after adjusting for sample size, conclusion of study, and RCT design: adjusted hazard ratio, 1.80 (95

    The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Índice Médico Español, and Índice Bibliográfico Español en Ciencias de la Salud. Of 300 abstracts, 115 resulted in 147 full publications, representing a publication rate of 38.33%. The meeting with the highest publication rate (43%) was held in 2005. The subject category with the highest number of publications was Pediatric Cardiology/Congenital Heart Disease (58.8%). Time to full publication was usually 2 years (30.61%). Articles were published in 57 journals. The journals publishing the highest number of articles were Revista Española de Cardiología (n=55; 37.41%) and the European Heart Journal (n=8; 5.44%). The high percentage of articles published in the upper half of journals listed in Journal Citation Reports under the category of cardiac and cardiovascular system (83%) can be taken as an objective quality indicator of the results presented at these meetings. However, more than 60% of the abstracts did not result in full publications, thus depriving the scientific community of potentially interesting results.

    To determine the publication rates of podium presentation abstracts at the Arthroscopy Association of North America (AANA) annual scientific meetings from 2004 to 2012. A database of podium presentation abstracts at the annual meetings of the AANA was compiled. Abstract presentations that reached manuscript publication were determined by a PubMed search of the MEDLINE database and Google Scholar. The journal and publication date were then recorded for all identified published abstracts. A total of 658 abstracts were selected for podium presentations at AANA annual meetings from 2004-2012 (range, 53-102 per year). Of these 658 abstracts, 443 (67.3%) went on to eventual publication in peer-reviewed journals. The mean time from the meeting to publication was 20.0 months. Most abstracts were published within 3 years of the meeting (n = 380, 85.8%), with a significant number of published abstracts reaching publication before the time of the meeting (n = 41, 9.3%). Published abstracts were most frequently published in Arthroscopy (n = 186, 42.0%), The American Journal of Sports Medicine (20.3%), and The Journal of Bone and Joint Surgery (6.1%). The overall publication rate of podium presentations at AANA annual meetings (67.3%) was similar to publication rates for other major orthopaedic annual meetings. Most published abstracts (85.8%) were published within 3 years, and the mean time to publication was 20.0 months. The rates of publication of podium presentations at AANA annual meetings show the impact and importance of these meetings in the advancement of orthopaedic research.

    The purpose of this study was to determine publication rates of all abstracts submitted for presentation at the annual conference of the Pediatric Orthopaedic Society of North America (POSNA) comparing papers accepted for presentation with those that were not accepted and to determine the median times to publication and the mean impact factor of journals that published papers from the 2 groups. The titles and authors of all abstracts submitted for presentation to the POSNA for the years 2003 to 2005 were identified. To determine publication status, we conducted a computerized Pubmed search using the first author's name. If multiple publications were identified, the Boolean search operator AND was used to combine author names with key words. The title of each located published article was compared with the title of the abstract. If differences were noted, the abstract content was compared with the final publication. The journals, impact factor was determined using the journal citation report. The median time from conference presentation to publication was determined using a Kaplan-Meier survival analysis. Of 1191 abstracts submitted to the annual meetings of POSNA from the years 2003 through 2005, 440 (37%) were accepted for presentation. Acceptance of submitted abstracts increased from 30% in 2003 to 40% in 2005. Of the 1191 abstracts 599 (50%) were subsequently published by August 2009. The mean publication rate for abstracts accepted for presentation was 58.9% (259 of 440) compared with 45% (339 of 751) for rejected abstracts. The median time to publication of accepted abstracts was not significantly different when compared with that of rejected abstracts. The mean journal impact factor for accepted articles was 2.2 compared with 1.5 for rejected abstracts. The publication rates of abstracts submitted to POSNA is high compared with those of other international orthopaedic associations. The mean publication rate for accepted abstracts and rejected abstracts has

  17. Extended abstracts for an international conference on the development of the North and problems of recultivation

    Ecological problems in many regions on Earth are the result of increasing technological pressure on the environment. These problems concern many of us and cause mankind to unite in order to search for means to protect the environment. Scientists, especially are responsible for the protection of the biosphere. The objective of this conference was to discuss the results of studies on the present condition of the environment in the Far North where the industrial pressure is increasing. The participants of this conference also offered and suggested various necessary measures for the protection of the region and restoration of its disturbed sites. The specific structural characteristics of the environment of the Far North, tundra and northern taiga, cause its fragility and vulnerability to anthropogenic impact. The destruction of the thin, weak layer of soil and vegetation cover changes the thermal balance and thus causes the development of erosion process, which in their turn increase the zone of the direct technogenous destruction. Self restoration processes in this harsh climate usually are slow. The preservation of the ecological integrity in the Far North is essential for the stability of the biosphere of the planet. The specifics of the natural conditions must be taken into account so that man will be able to develop the means of intensive agro-technology that can speed up the process of restoration of the biocenosis in the damaged areas. The extended abstracts of the conference reports that constitute this volume contain both theoretical discussions of problems of recultivation as well as accounts of experimental studies and applied explorations.

    Though volcanic eruptions are comparatively rare in the American Southwest, the States of Arizona, Colorado, New Mexico, Nevada, and Utah host Holocene volcanic eruption deposits and are vulnerable to future volcanic activity. Compared with other parts of the western United States, comparatively little research has been focused on this area, and eruption probabilities are poorly constrained. Monitoring infrastructure consists of a variety of local seismic networks, and ”backbone“ geodetic networks with little integration. Emergency response planning for volcanic unrest has received little attention by either Federal or State agencies. On October 18–20, 2012, 90 people met at the U.S. Geological Survey campus in Flagstaff, Arizona, providing an opportunity for volcanologists, land managers, and emergency responders to meet, converse, and begin to plan protocols for any future activity. Geologists contributed data on recent findings of eruptive ages, eruption probabilities, and hazards extents (plume heights, ash dispersal). Geophysicists discussed evidence for magma intrusions from seismic, geodetic, and other geophysical techniques. Network operators publicized their recent work and the relevance of their equipment to volcanic regions. Land managers and emergency responders shared their experiences with emergency planning for earthquakes. The meeting was organized out of the recognition that little attention had been paid to planning for or mitigation of volcanic hazards in the American Southwest. Moreover, few geological meetings have hosted a session specifically devoted to this topic. This volume represents one official outcome of the meeting—a collection of abstracts related to talks and poster presentations shared during the first two days of the meeting. In addition, this report includes the meeting agenda as a record of the proceedings. One additional intended outcome will be greater discussion and coordination among emergency responders, geologists

    Retrospective review of conference abstracts. To determine the publication rate of podium and poster presentations at the 2010-2012 North American Spine Society (NASS) annual meetings. Presentations at medical conferences are utilized to disseminate new clinical information. The orthopaedic literature estimates the rate of publication for abstracts presented at major meetings to be between 34.0-67.1%. However, few studies have analyzed the publication rate of accepted abstracts to the NASS annual meetings. All abstracts presented at the 2010-2012 NASS annual meetings were reviewed. PubMed and Google Scholar databases were searched to determine if each abstract was published as a full-length manuscript before or up to 3 years after its NASS meeting presentation. Statistical analyses included descriptive statistics, poisson regression with robust error variance, and linear regression. A total of 1045 abstracts were accepted to the 2010-2012 NASS annual meetings. 43.8% were published before or up 3 years after their NASS presentation. Podium presentations were more likely to be published than poster presentations (47.1% vs. 37.7%, p = 0.005). Abstracts with "Best" or "Outstanding" designations were also more likely to be published than abstracts without those designations (54.4% vs. 45.0%, p = 0.034). Presentations designated as "Best" or "Outstanding" papers had shorter time to publication than presentations without those designations (369 vs 486 days, p = 0.002). This study suggests that only 43.8% of abstracts accepted to NASS are published as full-length manuscripts. As such, practitioners should use caution when altering clinical practice based solely on conference presentations. Additionally, podium presentations are more likely to be published than poster presentations. This trend may be reflective of the higher quality of abstracts accepted as podiums, or may be associated with a larger number of lower quality abstracts being accepted due to the

    to assess the conversion rate of Plastic Surgery meeting abstract presentations to full manuscript publications and examine factors associated with this conversion. we assessed the abstracts presented at the 47th and 48th Brazilian Congresses of Plastic Surgery by cross-referencing with multiple databases. We analyzed the Abstracts' characteristics associated with full manuscript publications. of the 200 abstracts presented, 50 abstracts were subsequently published in full, giving the conference a conversion rate of 25%. The mean time to publish was 15.00±13.75 months. In total, there were 4.93±1.63 authors per abstract and 67.8±163 subjects per abstract; 43.5% of the abstracts were of retrospective studies; 69% comprised the plastic surgery topics head and neck, and chest and trunk, and 88.5% had no statistical analysis. Overall, 80% of the manuscripts were published in plastic surgery journals, 76% had no impact factor and 52% had no citations. Bivariate and multivariate analyses revealed the presence of statistical analysis to be the most significant (p<0.05) predictive factor of conversion of abstracts into full manuscripts. the conversion rate found from this bibliometric research appeared a bit lower than the conversion trend of international plastic surgery meetings, and statistical analysis was a determinant of conversion success. avaliar a taxa de conversão de resumos apresentados em congressos de Cirurgia Plástica em publicações de manuscritos completos e examinar fatores associados a essa conversão. resumos apresentados nos XLVII e XLVIII Congressos Brasileiros de Cirurgia Plástica foram avaliados por meio de referências cruzadas em diversos bancos de dados.

    covered a wide range of ongoing inter-disciplinary research, including studies of sediment geochemistry of aquatic environments, sediment budgets, tracking fish pathways, expansion of invasive forams, beach and nearshore sedimentary environments, using influence diagrams as a decision support tool, forage fish, submarine groundwater, and much, much more. The primary focus within these themes was on developing information on the physical, chemical, and biological processes, as well as the human dimensions, associated with the restoration or rehabilitation of the nearshore environment. The workshop was an excellent opportunity for USGS scientists and collaborators who are working on Puget Sound coastal habitats to present their preliminary findings, discuss upcoming research, and to identify opportunities for interdisciplinary collaboration. A compilation of extended abstracts from workshop participants, this proceedings volume serves as a useful reference for attendees of the workshop and for those unable to attend. Taken together, the abstracts in this report provide a view of the current status of USGS multidisciplinary research on Puget Sound coastal habitats.

    . This is the largest reported study examining why oncology trials are not published. The data show that 4−6 years after appearing as abstracts, 39% of oncology clinical trials remain unpublished. Larger sample size and advanced trial phase were associated with eventual publication; among randomized trials, an industry-affiliated author or a cooperative group increased likelihood of publication. Unfortunately, we found that, despite widespread recognition of the problem and the creation of central data repositories, timely publishing of oncology clinical trials results remains unsatisfactory. Implications for Practice: The Declaration of Helsinki Ethical Principles for Medical Research Involving Human Subjects notes the ethical obligation to report clinical trial data, whether positive or negative. This obligation is listed alongside requirements for risk minimization, access, confidentiality, and informed consent, all bedrocks of the clinical trial system, yet clinical trials are often not published, particularly if negative or difficult to complete. This study found that among American Society for Clinical Oncology (ASCO) Annual Meeting abstracts, 2009–2011, only 61% were published 4–6 years later: 75% of randomized trials and 54% of nonrandomized trials. Clinicians need to insist that every study in which they participate is published. PMID:26888691

    Introduction Report of the Annual Mappers Meeting Planetary Science Institute Tucson, Arizona June 28 and 29, 2007 Approximately 22 people attended this year's mappers meeting, and many more submitted abstracts and maps in absentia. The 2007 meeting was convened by Tracy Gregg, Les Bleamaster, Steve Saunders, and Ken Tanaka and was hosted by David Crown and Les Bleamaster of the Planetary Science Institute (PSI) in Tucson, Arizona. Oral presentations and poster discussions took place on Thursday, June 28 and Friday, June 29. This year's meeting also included a unique opportunity to visit the operations centers of two active Mars missions; field trips to the University of Arizona took place on Thursday and Friday afternoons. Outgoing Geologic Mapping Subcommittee (GEMS) chairperson, Tracy Gregg, commenced the meeting with an introduction and David Crown followed with a discussion of logistics and the PSI facility; Steve Saunders (Planetary Geology and Geophysics Discipline Scientist) then provided a brief program update. Science presentations kicked off with Venus mapper Vicki Hansen and graduate students Eric Tharalson and Bhairavi Shankar of the University of Minnesota, Duluth, showing a 3-D animation of the global distribution of tesserae and discussing the implications, a progress report for V-45 quadrangle mapping, and a brief discussion of circular lows. Les Bleamaster (PSI) followed with a progress report on mapping of the V-50 quadrangle and the 1:10M Helen Planitia quadrangle. David Crown (PSI) concluded the Venus presentations with a discussion of progress made on the V-30 quadrangle. The remainder of Thursday's presentations jumped around the Solar System including Mars, Io, and Earth. Ken Tanaka of the U.S. Geological Survey (USGS) began the afternoon with a general discussion of the status of the planetary mapping program at USGS. Buck Janes (University of Arizona) provided background information about the Mars Odyssey Gamma Ray Spectrometer (GRS) and

    Dissemination of research studies is important for research ideas to be transformed from initial abstracts to full publications. Analyses of the scientific impact and publication record of the Canadian Rheumatology Association (CRA) Annual meeting have not been previously described. This study determines the publication rate of abstracts presented at the CRA Annual Meetings 2005-2013 to full-text journal articles and the factors associated with publication. Program records of previous CRA meetings from 2005 to 2013 were obtained. Abstracts were searched for corresponding full-text publication in Google Scholar and PubMed using a search algorithm. Abstracts and subsequent published articles were evaluated for type of abstract, time to publication, study type, publishing journal, and journal impact factor. A total of 1401 abstracts were included in the study, 567 of which were converted to full publications. The average time to publication was 19.7 months, with 89% of abstracts published within 3 years of being presented. Eighty-three percent of abstracts were clinical in nature, and 58% of published studies were observational in design. Articles were published in a wide range of journals, with the top publisher being the Journal of Rheumatology (31%). Average time to publication was 19.7 months. Eighty-six percent of articles had a Journal Impact Factor > 2. Overall, 40.5% of abstracts presented at the CRA Annual Meetings 2005-2013 were published. Further research is needed to determine barriers and reasons for abstracts not being published as full-text articles.

    Helicopters have the potential to be an integral part of the future transport system. They offer a means of rapid transit in an overly populated transport environment. However, one of the biggest limitations on rotary wing flight is their inability to fly in degraded visual conditions in the critical phases of approach and landing. This paper presents a study that developed and evaluated a Head up Display (HUD) to assist rotary wing pilots by extending landing to degraded visual conditions. The HUD was developed with the assistance of the Cognitive Work Analysis method as an approach for analysing the cognitive work of landing the helicopter. The HUD was tested in a fixed based flight simulator with qualified helicopter pilots. A qualitative analysis to assess situation awareness and workload found that the HUD enabled safe landing in degraded conditions whilst simultaneously enhancing situation awareness and reducing workload. Continued development in this area has the potential to extend the operational capability of helicopters in the future.

    As a primary venue for presenting research results, abstracts selected for presentation at national meetings should be of the highest scientific merit and research quality. It is uncertain to what degree this is achieved as the methodological quality of abstracts submitted to national surgical meetings has not been previously described. The objective of this study was to evaluate abstracts presented at a leading trauma meeting for methodological quality. All abstracts accepted for the 2009 American Association for the Surgery of Trauma meeting were reviewed and scored for methodological quality based on 10 criteria (scores, 0-10; 10 being the highest). Criteria were based on nationally published methodology guidelines. Two independent reviewers who were blinded to institution, region, and author reviewed each abstract. A total of 187 abstracts were accepted for presentation (67 oral and 120 posters). The most frequent clinical topics were shock/transfusion (23%), abdomen (12%), and nervous system (11%). Shock/transfusion abstracts were more common in the oral presentations (31% vs. 19%; p = 0.06). Abstracts from the northeast and south regions were the most common in both oral (26% and 29%) and posters (25% and 24%). Basic science accounted for 12% of accepted studies, while 51% were clinical and 28% were health services/outcomes. Only 8% of abstracts presented randomized data and only 11% reported null findings. Overall abstract scores ranged from 3 to 10 (median, 7; mean, 7.4). Abstracts selected for poster presentation had an overall higher score than those selected for oral presentation (7.4 ± 1.7 vs. 6.8 ± 1.7; p = 0.02). Although oral presentations traditionally receive the most attention and interest, the methodological quality of abstracts accepted for poster presentation equals (and sometimes exceeds) that of oral abstracts. Attendees of these national meetings should reconsider their time spent in viewing and visiting these poster sessions as with the

    The expected knowledge translation from discovery into practice occurs when presentations from major scientific meetings are published in peer-reviewed literature. The purpose of this study was to determine the extent of complete publication of peer-reviewed articles arising from presentations at the biennial meetings of the Pan-African Pediatric Surgical Association (PAPSA). All the abstracts accepted for presentation at the biennial meeting of PAPSA between 2006 and 2010 were identified from the conference abstract booklets and published abstracts in the African Journal of Paediatric Surgery. The presentations were searched for publication in Medline/PubMed, Google Scholar, and African Journal OnLine through October 2012, using key words from the abstract title and names of authors listed in the abstracts. A total of 164 abstracts were accepted for presentation, consisting of 118 (72%) oral/podium presentations and 46 (28%) poster presentations. One hundred and thirty-three abstracts (81.1%) came from African countries and 31 (18.9%) from outside Africa. Overall, 49 (29.9%) abstracts resulted in full-text publications in 20 peer-reviewed journals. Thirty-eight of the publications were from Africa (representing 28.6% of abstracts from Africa) and 11 from outside Africa (33.3% of abstracts from outside Africa). The median time to publication was 15 months [interquartile range (IQR) 5-26 months]. The publication rate was statistically significantly correlated to the year of publication (P = 0.016) and the use of comparative statistics in the study (P = 0.005), but not to the study design, study subjects, or institution. The majority of the studies were published in the African Journal of Paediatric Surgery and Pediatric Surgery International (14 and 11 of the 49 reports, respectively). The H-index for international abstracts (median 35, IQR 35-76) was significantly higher than that of African abstracts (14, 3-35) (P = 0.002). Only a third of abstracts presented at

    Stardust, NASA's first dedicated sample return mission to a comet, successfully flew through the comet dust around Wold2 on January 2, 2004. The spacecraft flew within 236 km of the comet, meeting the mission requirement of 250+/- 50 km on flyby distance. Stardust collected dust particles and took several images of the comet while flying close to Wild2. The spacecraft will return to earth with the comet samples on January 15, 2006. To accomplish the above objective, a large Deep Space Maneuver (DSM#) was implemented during June 17 and 18, 2003 and a series of Trajectory Correction Maneuvers (TCMs) were also implemented during the 30 days prior to encounter. Both maneuver design and executions were influenced by number of factors including the small body ephemeris uncertainty, predictability of small forces arising from 3-axis attitude limit cycling and spacecraft slews. Maneuver design processes, including contingency plans, and maneuver performance characteristics, are discussed in this paper.

  18. Eighth workshop on crystalline silicon solar cell materials and processes: Extended abstracts and papers

    SciTech Connect

    1998-08-01

    The theme of this workshop is Supporting the Transition to World Class Manufacturing. This workshop provides a forum for an informal exchange of information between researchers in the photovoltaic and non-photovoltaic fields on various aspects of impurities and defects in silicon, their dynamics during device processing, and their application in defect engineering. This interaction helps establish a knowledge base that can be used for improving device fabrication processes to enhance solar-cell performance and reduce cell costs. It also provides an excellent opportunity for researchers from industry and universities to recognize mutual needs for future joint research. The workshop format features invited review presentations, panel discussions, and two poster sessions. The poster sessions create an opportunity for both university and industrial researchers to present their latest results and provide a natural forum for extended discussions and technical exchanges.

  19. An Intuitive Approach to Geometric Continuity for Parametric Curves and Surfaces (Extended Abstract)

    NASA Technical Reports Server (NTRS)

    Derose, T. D.; Barsky, B. A.

    1985-01-01

    The notion of geometric continuity is extended to an arbitrary order for curves and surfaces, and an intuitive development of constraints equations is presented that are necessary for it. The constraints result from a direct application of the univariate chain rule for curves, and the bivariate chain rule for surfaces. The constraints provide for the introduction of quantities known as shape parameters. The approach taken is important for several reasons: First, it generalizes geometric continuity to arbitrary order for both curves and surfaces. Second, it shows the fundamental connection between geometric continuity of curves and geometric continuity of surfaces. Third, due to the chain rule derivation, constraints of any order can be determined more easily than derivations based exclusively on geometric measures.

  1. Retrospective of photography at NASA Ames Research Center from 1940 to 1996 (Extended Abstract)

    NASA Astrophysics Data System (ADS)

    Ponseggi, Bernard G.

    1997-05-01

    This paper deals with what is known as photo/optical instrumentation technology and/or technical photography. In 1940 this was called photography, in the late 40's the Civil Service Commission introduced a new classification called photography/technical to differentiate between still photographers and those engaging in recording engineering data. In October of 1958 a historic event took place, Congress transferred all of the duties of NACA to a newly formed agency called NASA, and with it came a call for systems that would keep up with new requirements. There was a need to change the type and style of equipment to keep up with the demands for more accurate information. Existing hardware was modified and new hardware was developed and designed to meet the new requirements of space travel of manned and unmanned orbital vehicles. This family of equipment had to withstand the rigors of space travel such as extremely high `G' forces, temperature changes and `O' gravity, while on earth we needed equipment to document launch of space vehicles as well as wind tunnel testing, rocket sled stands etc.. Some requirements were similar to those of launch vehicles, some were totally different and had other requirements, eventually they were all resolved. As electronic data systems became available NASA experimented with their use in data acquisition. This portion of this session will discuss the changes over the years and their effect on the acquisition of data, those that worked, as well as those that were a disappointment.

    Objectives: This study sought to ascertain the publication rate of abstracts presented at the annual meetings of the Medical Library Association (MLA) for the years of 2002 and 2003. The secondary objectives were to examine possible reasons for non-publication and factors influencing publication. Methods: A total of 442 abstracts from both meeting years, consisting of presented papers and posters, were examined. The 2 methods used to obtain a publication rate were literature searches and an online questionnaire sent to first authors. The questionnaire also asked abstract authors about reasons for non-publication and other factors that might have influenced their decisions about whether or not to submit the project for publication. Results: The overall publication rate from the survey was 26.5%, and the publication rate found via literature searching was 27.6%. The most common reason given for non-publication was time restrictions. Also notable was the large proportion of abstracts written by librarians working at universities and those having 25 or more years in the library profession. Discussion: Publication rates for abstracts presented at the Medical Library Association meetings for the years studied rank at the low end in comparison with other medical professional associations. Further research into factors affecting publication may reveal ways to increase this rate. PMID:20648260

    The American Society of Clinical Oncology Annual Meeting is the largest forum for presentation of clinical research in oncology. We quantified the contribution of countries and assessed correlates of their presence at such meetings. After stratifying abstracts according to category of presentation (oral, poster, and 'publication only'), we took a random sample of 10% of the studies presented at years 2001-2003 and 2006-2008. We assigned abstract nationality using the affiliation of authors. For multinational studies, we developed an algorithm to assign nationality. Of the 22 045 eligible abstracts, 2206 were analyzed and represented 71 countries: 905 (41%) abstracts were from a single institution, 969 (44%) were multicenter, uninational studies, and 332 (15%) were multinational studies. United States nationality was assigned to 49% of all abstracts and the next 14 countries with a higher number of studies accounted for 41%. There was a statistically significant temporal trend in the proportion of multinational studies. Also, multinational studies and abstracts with United States nationality were more frequently presented in oral and poster fashion and had more frequent involvement of the pharmaceutical industry. This study provides a geographic overview of clinical cancer research and indicates that multinational collaboration is increasing.

    Oral and poster presentations at annual national meetings of the Romanian Society of Gastroenterology and Hepatology (RSGH) provide a forum for education, communication and discussion of new research. However, for the wide-spread dissemination of the new research work, each presentation should be subsequently published as a full-text article in peer-reviewed, indexed journals. to evaluate the publication rate of full-text articles in peer-reviewed journals after being first presented as abstracts at two consecutive RSGH annual meetings. A retrospective review of all abstracts presented at the annual meetings in 2013 and 2014 was performed. PubMed and Google Scholar were searched using abstract titles, first author's name and affiliation, and key words from the title to identify whether an abstract resulted in a peer-reviewed publication. Abstracts published in full-text were subsequently assessed for study type, study center, topics, publication year, journals and their impact factors (IFs). We chose the 2013 and 2014 meetings to ensure a minimum two-year follow-up period since the last meeting for the publication as full-length articles. A total of 562 abstracts were presented (275 in 2013, 287 in 2014). There were 150 oral presentations (93 in 2013, 57 in 2014) and 412 poster presentations (182 in 2013, 230 in 2014). Fifty seven of them (10.1%) were published as full-text articles, among them 26 (17.3%) after oral presentations and 31 (7.5%) after poster presentations (P=0.001). University affiliation and original research work were most likely to be published. The average IFs of the journals which published the articles were 2.42 in 2013 and 1.87 in 2014. The publication rate for the annual RSGH meetings abstracts as full-text articles in peer-reviewed journals is very low compared to the analyses performed in gastroenterology or other medical specialities from other countries. It is not clear yet what are the factors responsible for the failure of publication.

    Approximately 18 people attended this year's mappers meeting, and many more submitted abstracts and maps in absentia. The meeting was held on the campus of Northwest Nazarene University (NNU), and was graciously hosted by NNU's School of Health and Science. Planetary mapper Dr. Jim Zimbelman is an alumnus of NNU, and he was pivotal in organizing the meeting at this location. Oral and poster presentations were given on Friday, June 30. Drs. Bill Bonnichsen and Marty Godchaux led field excursions on July 1 and 2. USGS Astrogeology Team Chief Scientist Lisa Gaddis led the meeting with a brief discussion of the status of the planetary mapping program at USGS, and a more detailed description of the Lunar Mapping Program. She indicated that there is now a functioning website (http://astrogeology.usgs.gov/Projects/PlanetaryMapping/Lunar/) which shows which lunar quadrangles are available to be mapped. Like other USGS-published maps, proposals to complete a lunar geologic map must be submitted to the regular Planetary Geology & Geophysics (PGG) program for peer review. Jim Skinner (USGS) later presented the progress of the 1:2.5M-scale map of the lunar Copernicus quadrangle, and demonstrated the wide range of data that are available to support these maps. Gaddis and Skinner encouraged the community to submit proposals for generating lunar geologic maps, and reminded us that, as for all planetary maps, the project must be science-driven. Venus mapper Jim Zimbelman of the Smithsonian Institution (SI) presented the progress for his V-15 and V-16 quadrangles; Vicki Hansen (University of Minnesota Duluth) showed her preliminary work on V-45. Zimbelman addressed an issue that has been plaguing the community: 'delinquent Venus mappers'. In short, there were a number of Venus maps funded in the early 1990s under the Venus Data Analysis Program (VDAP). Unfortunately, funding for this program was cut before many Venus maps could be completed, resulting in about 10 Venus maps that

    To analyze publication rate, time to publication and the characteristics of the abstracts presented at the annual Korean Academy of Rehabilitation Medicine (KARM) meetings. A total of 1,027 abstracts presented at the 2008 and 2009 annual KARM meetings were enrolled in the database and searched for their subsequent citation in PubMed, KoreaMed, and Google Scholar. The data analysis revealed that 317 (30.87%) abstracts, were published as full-length journal articles and publication rates by subject were not significantly different. The mean time to publication was 17.17±10.48 months, and the journals written in English (20.39±10.20) required a longer duration than those written in Korean (11.94±8.44) with statistical significance (p<0.001). There was no statistical difference (p=0.284) in the duration between domestic (17.61±10.37) and foreign (16.48±10.51) of the 220 domestic journal articles, 190 (86.76%) were published in the Annals of Rehabilitation Medicine and the 97 articles published in foreign journals were scattered over 60 different journals. The publication rate of abstracts presented at the 2008 and 2009 annual KARM meetings was 30.87% and the mean time to publication was 17.17±10.48 months.

    The quality of the abstracts presented at a conference reflects the scientific work and level of activity of the scientific association concerned. The aim of the present study was to determine the rate of publications of podium presentations and posters at the conferences of the European Paediatric Orthopaedic Society (EPOS) from 2006 to 2008 and to identify factors that favor publication in peer-reviewed journals. The results are compared with those of other international societies. All 646 abstracts (including podiums, posters, and e-posters) presented at the EPOS conferences were investigated using the PubMed database to identify any corresponding published articles in the journals listed in the database. A period of 5 years before and after the relevant conference was used for the PubMed search. Factors influencing publication and the quality of the study, such as the type of presentation and the level of evidence, were also investigated. A publication rate of 36.7% was observed, corresponding to 237 publications of 646 abstracts. The period to publication showed a mean of 13.88 ± 1.34 months. It was found that abstracts of podium presentations were published significantly more often than poster abstracts (P<0.001). Experimental studies, with a publication rate of 50.9%, showed better results than clinical studies (36.0%). Overall, the articles were published in 61 different journals, with the largest number (n=50) appearing in the Journal of Pediatric Orthopaedics. In addition, the present study shows that abstracts with a higher level of evidence were associated with a higher publication rate. At 36.7%, the rate of publication of EPOS abstracts is within the range reached by other specialist orthopaedics societies, such as the German Society of Orthopaedics and Trauma Surgery (36%) and the British Orthopaedic Association (36%). However, it is lower than the publication rate of the Pediatric Orthopaedic Society of North America (POSNA), at 50%. The high

    Despite the ethical imperative to publish clinical trials when human subjects are involved, such data frequently remain unpublished. The objectives were to tabulate the rate and ascertain factors associated with eventual publication of clinical trial results reported as abstracts in the Proceedings of the American Society of Clinical Oncology (American Society of Clinical Oncology). Abstracts describing clinical trials for patients with breast, lung, colorectal, ovarian, and prostate cancer from 2009 to 2011 were identified by using a comprehensive online database (http://meetinglibrary.asco.org/abstracts). Abstracts included reported results of a treatment or intervention assessed in a discrete, prospective clinical trial. Publication status at 4-6 years was determined by using a standardized search of PubMed. Primary outcomes were the rate of publication for abstracts of randomized and nonrandomized clinical trials. Secondary outcomes included factors influencing the publication of results. A total of 1,075 abstracts describing 378 randomized and 697 nonrandomized clinical trials were evaluated. Across all years, 75% of randomized and 54% of nonrandomized trials were published, with an overall publication rate of 61%. Sample size was a statistically significant predictor of publication for both randomized and nonrandomized trials (odds ratio [OR] per increase of 100 participants = 1.23 [1.11-1.36], p < .001; and 1.64 [1.15-2.34], p = .006, respectively). Among randomized studies, an industry coauthor or involvement of a cooperative group increased the likelihood of publication (OR 2.37, p = .013; and 2.21, p = .01, respectively). Among nonrandomized studies, phase II trials were more likely to be published than phase I (p < .001). Use of an experimental agent was not a predictor of publication in randomized (OR 0.76 [0.38-1.52]; p = .441) or nonrandomized trials (OR 0.89 [0.61-1.29]; p = .532).

    The annual Planetary Geologic Mappers Meeting serves two purposes. In addition to giving mappers the opportunity to exchange ideas, experiences, victories, and problems with others, presentations are reviewed by the Geologic Mapping Subcommittee (GeMS) to provide input to the Planetary Geology and Geophysics Mapping Program review panel’s consideration of new proposals and progress reports that include mapping tasks. Funded mappers bring both oral presentation materials (slides or viewgraphs) and map products to post for review by GeMS and fellow mappers. Additionally, the annual meetings typically feature optional field trips offering earth analogs and parallels to planetary mapping problems. The 2001 Mappers Meeting, June 18-19, was convened by Tim Parker, Dave Senske, and Ken Tanaka and was hosted by Larry Crumpler and Jayne Aubele of the New Mexico Museum of Natural History and Science in Albuquerque, New Mexico. Oral presentations were given in the Museum’s Honeywell Auditorium, and maps were posted in the Sandia Room. In addition to active mappers, guests included local science teachers who had successfully competed for the right to attend and listen to the reports. It was a unique pleasure for mappers to have the opportunity to interact with and provide information to teachers responding so enthusiastically to the meeting presentation. On Sunday, June 17, Larry and Jayne conducted an optional pre-meeting field trip. The flanks of Rio Grande Rift, east and west of Albuquerque and Valles Caldera north of town presented tectonic, volcanic, and sedimentary examples of the Rift and adjoining areas analogous to observed features on Mars and Venus. The arid but volcanically and tectonically active environment of New Mexico’s rift valley enables focus on features that appear morphologically young and spectacular in satellite images and digital relief models. The theme of the trip was to see what, at orbiter resolution, "obvious" geologic features look like at

    Annual meeting abstracts published by scientific societies often contain rich arrays of information that can be computationally mined and distilled to elucidate the state and dynamics of the subject field. We extracted and processed abstract data from the Society for Neuroscience (SFN) annual meeting abstracts during the period 2001–2006 in order to gain an objective view of contemporary neuroscience. An important first step in the process was the application of data cleaning and disambiguation methods to construct a unified database, since the data were too noisy to be of full utility in the raw form initially available. Using natural language processing, text mining, and other data analysis techniques, we then examined the demographics and structure of the scientific collaboration network, the dynamics of the field over time, major research trends, and the structure of the sources of research funding. Some interesting findings include a high geographical concentration of neuroscience research in the north eastern United States, a surprisingly large transient population (66% of the authors appear in only one out of the six studied years), the central role played by the study of neurodegenerative disorders in the neuroscience community, and an apparent growth of behavioral/systems neuroscience with a corresponding shrinkage of cellular/molecular neuroscience over the six year period. The results from this work will prove useful for scientists, policy makers, and funding agencies seeking to gain a complete and unbiased picture of the community structure and body of knowledge encapsulated by a specific scientific domain.

    Earlier studies have indicated that across medical specialties, the overall publication rate of submitted manuscripts ranges from 36% to 66%. However, there have not been any recent studies conducted concerning the publication rates specifically for the Pediatric Orthopaedic Society of North America (POSNA). Consequently, the purpose of our study was to determine the overall publication rates of abstracts presented during the POSNA annual meetings, and whether there were differences in publication rates and time to publication according to type of presentation (podium vs. poster), journal, and orthopaedic subspecialty. A comprehensive literature search using PubMed and Google Scholar for all abstracts (including podiums, posters, and e-posters) presented at the 2002 to 2006 POSNA annual meetings was performed. Abstracts were classified according to presentation type: podium, poster, or e-posters, and were subsequently categorized into a specific orthopaedic subspecialty: basic science, hip, lower extremities, spine, trauma, and upper extremity. A total of 762 abstracts were presented at POSNA meetings between the years of 2002 and 2006. Of these 762 abstracts, 386 (50.7%) were published in peer-reviewed literature. There was no significant variation in the yearly publication percentage rate between 2002 and 2006 (P=0.63). However, overall time between presentation at POSNA and publication in a peer-reviewed journal varied significantly by year (P=0.002), with the average time to publication being 29 months in 2002, compared with 18.8 months in 2006. Time to publication also varied significantly by journal (P=0.025). For the combined years of 2002 to 2006, podiums were 1.47 times (95% confidence interval, 1.10-1.98) more likely to be published compared with posters (P=0.009). When abstracts were stratified by subspecialty (trauma, spine, hip, basic science, lower extremity, and upper extremity), there was no difference in publication rate between each group (P=0

Additionally, the annual meetings typically feature optional field trips that offer Earth analogs and parallels to planetary mapping problems or workshops that provide information and status of current missions. The 2002 meeting of planetary geologic mappers was held June 21-22 at the Mars Flight Facility, Arizona State University, Tempe, Arizona. Dr. Phil Christensen graciously offered the use of the newly renovated facility, and Ms. Kelly Bender not only proved to be a courteous hostess, but also arranged a short workshop on June 23 regarding TES and THEMIS data. Approximately 30 people attended each day of the 2-day meeting, although not the same 30—some attended only on Thursday and others only on Friday. On Thursday, eight mappers gave oral presentations of Mars mapping, and an additional two presentations were presented as posters only. Eight oral presentations on Venus mapping were given on Friday, and an additional four presentations were posters only. Twelve people attended the TES/THEMIS workshop. Presentations of Ganymede mapping and Europa mapping (the latter not yet financially sponsored by PG&G mapping program) were also given on Friday. Aside from the regular presentations of maps-in-progress, there were some additional talks. Lisa Gaddis (USGS) presented a proposal seeking support for a new lunar mapping program in light of all the new data available; she made a good case that the GEMS panel discussed.

    Studies reveal that 44.5% of abstracts presented at national meetings are subsequently published in indexed journals, with lower rates for abstracts of medical education scholarship. We sought to determine whether the quality of medical education abstracts is associated with subsequent publication in indexed journals, and to compare the quality of medical education abstracts presented as scientific abstracts versus innovations in medical education (IME). Retrospective cohort study. Medical education abstracts presented at the Society of General Internal Medicine (SGIM) 2009 annual meeting. Publication rates were measured using database searches for full-text publications through December 2013. Quality was assessed using the validated Medical Education Research Study Quality Instrument (MERSQI). Overall, 64 (44%) medical education abstracts presented at the 2009 SGIM annual meeting were subsequently published in indexed medical journals. The MERSQI demonstrated good inter-rater reliability (intraclass correlation range, 0.77-1.00) for grading the quality of medical education abstracts. MERSQI scores were higher for published versus unpublished abstracts (9.59 vs. 8.81, p = 0.03). Abstracts with a MERSQI score of 10 or greater were more likely to be published (OR 3.18, 95% CI 1.47-6.89, p = 0.003). ). MERSQI scores were higher for scientific versus IME abstracts (9.88 vs. 8.31, p < 0.001). Publication rates were higher for scientific abstracts (42 [66%] vs. 37 [46%], p = 0.02) and oral presentations (15 [23%] vs. 6 [8%], p = 0.01). The publication rate of medical education abstracts presented at the 2009 SGIM annual meeting was similar to reported publication rates for biomedical research abstracts, but higher than publication rates reported for medical education abstracts. MERSQI scores were associated with higher abstract publication rates, suggesting that attention to measures of quality--such as sampling, instrument validity, and data analysis

    Since its inception in 1989, Clerkship Directors in Internal Medicine (CDIM) has promoted excellence in medical student education. CDIM members move medical education forward by sharing innovations in curriculum and assessment and discoveries related to educating our students and administering our programs. The Alliance for Academic Internal Medicine, of which CDIM is a founding member, broadens the umbrella beyond student education to include five academically focused specialty organizations representing departments of medicine, teaching hospitals, and medical schools working together to advance learning, discovery, and caring. CDIM held its 2015 annual meeting at Academic Internal Medicine Week in Atlanta, Georgia. This year 36 innovation and research submissions were selected for either oral abstract or poster presentation. The quality of the presentations was outstanding this year and included many of the most important issues in medical education. The CDIM research committee selected the following seven abstracts as being of the highest quality, the most generalizable, and relevant to the readership of Teaching and Learning in Medicine. Two abstracts include information from the CDIM annual survey, which remains a rich source for answering questions about student education on a national level. Looking at trends in medical education, three of the seven selected abstracts mention entrustable professional activities. Three of the abstracts address how we assess student skill and provide them with appropriate feedback. These include two schools' approach to bringing milestones into the medical student realm, use of objective structured clinical exam for assessing clinical skill in clerkship, and what students want in terms of feedback. Four articles deal with curricular innovation. These include interprofessional education, high-value care, transitions of care, and internship preparation.

  20. Nonlinear optical properties of rhenium(I) complexes: Influence of the extended π-conjugated connectors and proton abstraction.

    The photoinduced proton-coupled electron transfer chemistry is very crucial to the development of nonlinear optical (NLO) materials with large first hyperpolarizability contrast. We have performed a systematic investigation on the geometric structures, NLO switching, and simulated absorption spectra of rhenium(I) complexes via density functional theory (DFT). The results show that the first hyperpolarizabilities (βvec) increase remarkably with further extending of the organic connectors. In addition, the solvent leads to a slight enhancement of the hyperpolarizability and frequency dependent hyperpolarizability. Furthermore, the proton abstraction plays an important role in tuning the second-order NLO response. It is found that deprotonation not only increases the absolute value of βvec but also changes the sign of βvec from positive to negative. This different sign can be explained by the opposite dipole moments. The efficient enhancement of first hyperpolarizability is attributed to the better delocalization of the π-electron system and the more obvious degree of charge transfer. Therefore, these kinds of complexes might be promising candidates for designed as proton driven molecular second-order NLO switching. Copyright © 2015 Elsevier Inc. All rights reserved.

    The UK Extracellular Vesicles (UKEV) Forum meetings were born of the realization that there were a number of UK laboratories studying extracellular vesicle biology and using similar techniques but without a regular national meeting dedicated to EVs at which to share their findings. This was compounded by the fact that many of these labs were working in different fields and thus networking and sharing of ideas and best practice was sometimes difficult. The first workshop was organized in 2013 by Dr Charlotte Lawson, under the auspices of the Society for Endocrinology, led to the founding of the UKEV Forum and the organization of a British Heart Foundation sponsored 1-day conference held in London in December 2014. Although growing in size every year, the central aims of these workshops have remained the same: to provide a forum for discussion and exchange of ideas, to allow young scientists to present their data in the form of short talks and poster presentations and to discuss their work with more established scientists in the field. Here we include the presented abstracts for the 2015 1-day conference hosted by Cardiff University. This meeting was attended by approximately 130 delegates throughout the United Kingdom, but also attended by delegates from Belgium, Netherlands, France, Ireland and other nations. The day composed of plenary presentations from Prof Matthias Belting, Lund University, Sweden and Dr Guillaume van Niel, Institut Curie, Paris together with 10 short presentations from submitted abstracts. The topics covered were broad, with sessions on Mechanisms of EV production, EVs in Infection, EVs in Cancer and in Blood and Characterizing EVs in Biological fluids. This hopefully gives a reflection of the range of EV-related studies being conducted currently in the UK. There were also 33 poster presentations equally broad in subject matter.

    Background Subsequent publication rate of abstracts presented at meetings is seen as an indicator of the interest and quality of the meeting. We have analyzed characteristics and rate publication in peer-reviewed journals derived from oral communications and posters presented at the 1999 College on Problems of Drug Dependence (CPDD) meeting. Methods All 689 abstracts presented at the 1999 CPDD meeting were reviewed. In order to find the existence of publications derived from abstracts presented at that meeting, a set of bibliographical searches in the database Medline was developed in July 2006. Information was gathered concerning the abstracts, articles and journals in which they were published. Results 254 out of 689 abstracts (36.9%) gave rise to at least one publication. The oral communications had a greater likelihood of being published than did the posters (OR = 2.53, 95% CI 1.80-3.55). The average time lapse to publication of an article was 672.97 days. The number of authors per work in the subsequent publications was 4.55. The articles were published in a total of 84 journals, of which eight were indexed with the subject term Substance-Related Disorders. Psychopharmacology (37 articles, 14.5%) was the journal that published the greatest number of articles subsequent to the abstracts presented at the 1999 CPDD meeting. Conclusion One out of every three abstracts presented to the 1999 CPDD meeting were later published in peer-reviewed journals indexed in Medline. The subsequent publication of the abstracts presented in the CPDD meetings should be actively encouraged, as this maximizes the dissemination of the scientific research and therefore the investment.

    What's known on the subject? and What does the study add? It is well known that the transition of a presented abstract in a scientific meeting to a journal article improves the quality of the meeting and prevents an abstract being incorporated into meta-analyses or practice guidelines without proper appraisal. This is the first analysis of USANZ Annual Scientific Meeting abstracts' conversion to full publication. With relatively low publication rates compared to other international meetings, this review identifies the need for mechanisms to encourage USANZ researchers to convert their abstracts into published articles. The numbers and characteristics of the abstracts presented at the Annual Scientific Meetings (ASM) of the Urological Society of Australia and New Zealand (USANZ) that are converted to peer-reviewed publications have not previously been analysed and published. We undertook a review of all abstracts presented at the USANZ ASM from 2005 to 2009. A PubMed search was performed between 15 June and 15 July 2012, using a search algorithm to identify the full-text publications of the presented abstracts. Correlation between abstract characteristics and publication rate was then examined to distinguish the predictors for publications. Of 614 abstracts that were presented at USANZ ASM between 2005 and 2009, 183 papers were published, giving a publication rate of 29.80%. The papers were predominantly published in urological journals and were more likely to be published if they were presented by an international author or were retrospective studies or if basic science research. The mean (SD) time to publication was 14.46 (13.89) months and the mean Impact Factor of journals where papers were published was 2.90. The overall publication rate was relatively low compared with other urological meetings held in America and Europe. USANZ has a challenge of encouraging higher-quality research from the authors to further enhance its publication rate and consequently the

    The presentation and academic discussion of the latest scientific research is the central purpose of meetings like the annual meeting of the German Society of Neurosurgery (DGNC). The aim of this study was to investigate the publication rate of all oral and poster abstracts of the DGNC meeting 2012 held in Leipzig, Germany, in peer-reviewed journals and to identify factors that are associated with a higher publication rate. We reviewed all accepted oral and poster presentations of the meeting. Then a search in PubMed was performed to determine the publication rate within 3 years after the abstract submission deadline. We used the information to identify factors associated with a higher publication rate. The publication rate in a peer-reviewed journal was 40.4% for all presented abstracts. Overall, 41.5% of all poster presentations and 40.1% of all oral presentations were published within 3 years. Abstracts presenting prospective studies or university research had a statistically higher chance of publication. The average journal impact factor for all published abstracts was 2.99, and 81 different journals were chosen for publication. Overall, 40.4% of all presented abstracts at the 2012 DGNC were published in a peer-reviewed journal indexed in PubMed, which reflects the high scientific standard of this meeting. Prospective studies and studies presented by authors from universities had a higher chance of being published. Georg Thieme Verlag KG Stuttgart · New York.

    In the last decade the presence of Brazilian physicians in International Meetings of Dermatology has been expressive. In parallel it has also been expressive the submission of poster abstracts in those Meetings. Considering the meetings from 2005 to 2013, 379 posters were presented in meetings of the American Academy of Dermatology. Brazilian universities were the origin of 59.9%. The Brazilian Society of Dermatology's recognized residency programs were the origin of 69.9% of the presented posters. Considering the period from 2005 to 2010 (n = 165 posters) the papers effectively published were 19 (11.5%). PMID:28099621

    We investigated the self-reported barriers to publication for authors of abstracts presented at the most recent chiropractic scientific meetings for which publication rates are known, that is the 2006 to 2008 Association of Chiropractic Colleges Educational Conference and Research Agenda Conference (ACC/RAC) meetings. A 4-question electronic survey was sent via email to 1 of the listed authors for each abstract not published as a full paper within 4 years of the 2006 to 2008 ACC/RAC meetings. Each author was asked to complete the survey for only 1 abstract. Taking into account authors who appeared on more than 1 abstract, a link to the electronic survey was emailed to 111 potential participants. Of 111 participants, 67 completed a survey for a return rate of 60%. Over 80% (55/67) of the respondents were chiropractors who were faculty members at educational institutions. Of the subjects, 30% (20/67) indicated that the meeting abstract had either been published after 2012 or still was in the publishing process. For those who had not submitted a manuscript for publication, the most frequently cited barriers to publishing were pursuit of publishing as a low priority followed by a lack of time to prepare a manuscript. The main barriers to publishing in this sample were that publishing had a low priority compared to other possible uses of the abstract author's time and a perceived lack of time to pursue the publication process.

    We aimed to examine the impact and quality of the research presented in the Israel Society of Rheumatology (ISR) annual scientific meetings by measuring publication rates of the abstracts in peer-reviewed journals and investigating the factors that influenced publication. We examined the outcome of all 79 abstracts submitted to the ISR for the 1998-2000 annual meetings. A MEDLINE search of all abstracts, by authors, topics and keywords was performed. Senior authors of abstracts not found to be published in this search were interviewed regarding publication and factors influencing submission. We described the effect of variable factors on the rate of publication. As of September 2002, 63 (80%) abstracts were published in peer-reviewed journals or are currently in-press. Most abstracts were published in prominent journals (with a high impact factor). The majority of the abstracts (61%) were published in rheumatologic journals, 65% of the studies originated from tertiary centers and 19% of the studies were multicenter. The most common diseases studied were antiphospholipid syndrome (20%), systemic lupus erythematosus (19%) and inflammatory arthritis (18%). Most of the studies were of disease pathogenesis (35%) and clinical manifestations (33%). The most common study designs were basic science (34%). An overall 57% of the studies reported "positive" results and 9% reported "negative" results. None of the factors studied were associated with publication or non-publication. The main cause cited by authors for not publishing their abstract was lack of time to prepare a full paper or a desire to further expand the study. Within this group of 16 authors of abstracts, 11 authors still plan to submit a paper. The ISR annual meetings have an important clinical scientific impact as measured by the high rate of abstracts published as full length articles in leading peer-reviewed journals.

    The rate of English-written submissions is increasing in local meetings of non-English speaking countries. However, it seems that the quality of research and methodology of the studies has not progressed. This study aimed to evaluate the association of English writing and the acceptance for presentation following the peer-review process in the 13th Annual Research Congress of Iran's Medical Sciences Students (ARCIMSS). All 1817 complete abstracts submitted to the meeting were included in this cross-sectional study. Each was evaluated for the language of the text (English or Persian), final decision after peer review (accepted vs. rejected), presentation type (oral, poster discussion and poster) and the scores of reviewing process. There were 395 (21.7%) abstracts written in English and 1422 (78.3%) in Persian. The acceptance rate for English abstracts was 33.7% and for Persian 24.6% (OR = 1.56, 95% CI: 1.22-1.98). The rate of abstracts' acceptance for presentation in oral panels was significantly higher for English abstracts than for those in Persian (25.6% versus 15.7%, OR = 1.84, 95% CI: 1.14-2.99). By contrast, Persian abstracts were more likely to be accepted as poster panels than were English abstracts (74.9% versus 63.9%, OR = 1.68, 95% CI: 1.10-2.58). English-written abstracts have higher chance of acceptation in a non-English speaker country like Iran.

    Although the presentation of original research to learned societies is valuable, the target should be publication in a peer-reviewed journal. Therefore, the strength of a meeting may be assessed by the rate of the subsequent publication of papers from the presented abstracts. We conducted an analysis of abstracts presented at consecutive annual meetings of the Society for Cardiothoracic Surgery (SCTS) in Great Britain and Ireland over a 15-year period. Abstract books and other documentation from the 1993-2007 meetings were reviewed; abstracts from other major Cardiothoracic Surgery meetings held in 2007 were also reviewed. Medline was searched to identify the peer-reviewed publications arising from each work presented. For abstracts presented at SCTS in 2003-07, the factors potentially associated with publication were analysed by logistic regression. If no publications were identified, authors were contacted through a standardized email questionnaire to ascertain its status and reasons for non-publication. Over the 15-year period, 909 abstracts were presented at the SCTS meetings. The rate of publication rose from ~30% in the mid-1990s to consistently >60% from recent meetings, with a high of 81.3% from 2006. However, in comparison with other Cardiothoracic Surgery meetings in 2007, the chance of subsequent publication from SCTS (66.7%) was lower than from the European Association for Cardio-Thoracic Surgery (75.0%), the American Association for Thoracic Surgery (83.9%) and The Society of Thoracic Surgeons (72.5%) meetings. For abstracts presented at the last five SCTS meetings, publication was most commonly in a speciality journal (56.3%) and the median time for publication was 15 months (range -24 to 63 months) with 14 papers published prior to presentation at the meeting. On regression analysis, the only factor associated with publication was the study design comparing randomized trials and systematic reviews with other types of study (P < 0.01). Of the 90

    On behalf of the Subsurface Biogeochemical Research (SBR) program managers in the Climate and Environmental Sciences Division (CESD), Office of Biological and Environmental Research (BER), welcome to the 2011 SBR Principal Investigators meeting. Thank you in advance for your attendance and your presentations at this year's meeting. As the events in Japan continue to unfold, we are all reminded that the research we perform on radionuclide behavior in the environment has implications beyond legacy waste cleanup and in fact has its place in the discussion on the expanded use of nuclear power. As in the past, there are three broad objectives to the Principal Investigators meeting: (1) to provide opportunities to share research results and promote interactions among the SBR scientists and other invited guests; (2) to evaluate the progress of each project within the program; and (3) to showcase the scientific expertise and research progress over the past year to senior managers within the DOE Office of Science, the technology offices within DOE, and other invited attendees from other Federal Agencies. This past year has seen a few significant changes within BER and within the SBR program. In November, our Associate Director for BER, Anna Palmisano, retired from Federal service. Just this month, Dr. Sharlene Weatherwax (Division Director for Biological Systems Sciences) has been named as the new Associate Director for BER. In August, BER welcomed Dr. Gary Geernaert as the new Division Director for CESD. Gary joins the division from Los Alamos National Laboratory with a background in atmospheric science. Within the SBR program, a new Strategic Plan was completed last June (currently posted on the SBR and the Office of Science website). The new strategic plan is intended to foster integration within the Environmental Systems Science portion of the BER budget that includes both SBR and Terrestrial Ecosystem Sciences (TES). Both these programs share a goal of advancing a

    Publication bias (PB) is a threat to the validity of medical literature, and has not been studied in the field of pediatric hematology/oncology. We analyzed the abstracts presented at the 2005 American Society of Pediatric Hematology/Oncology annual meeting to assess for PB. Abstracts were categorized by type of research, number of centers, funding status, presentation format, sample size, statistical significance, and the direction of results. Publication status was determined by searching PubMed. Thirty nine abstracts (51%) were categorized as clinical studies, 67 (36%) as basic research, and 24 (13%) as others. One hundred and twenty three abstracts (67%) were considered to have positive results, 14 (8%) negative results, and 47 (25%) with neutral or not stated results. About 62% of the abstracts were published in peer-reviewed journals at a median time to publication of 19 months (IQR = 11-29 months). Abstracts with positive results were more likely to get published than others (combined negative and neutral results) (P = .002). Factors like sample size, number of centers, or statistical significance reporting did not affect the publication rate. Our data suggests the existence of PB in the field of pediatric hematology/oncology. Still, further analysis of other international meetings is needed to validate our findings.

    Global demand for mineral resources continues to increase because of increasing global population and the desire and efforts to improve living standards worldwide. The ability to meet this growing demand for minerals is affected by the concerns about possible environmental degradation associated with minerals production and by competing land uses. Informed planning and decisions concerning sustainability and resource development require a long-term perspective and an integrated approach to land-use, resource, and environmental management worldwide. This, in turn, requires unbiased information on the global distribution of identified and especially undiscovered resources, the economic and political factors influencing their development, and the potential environmental consequences of their exploitation. The purpose of the IGC workshop is to review the state-of-the-art in mineral-deposit modeling and quantitative resource assessment and to examine their role in the sustainability of mineral use. The workshop will address such questions as: Which of the available mineral-deposit models and assessment methods are best suited for predicting the locations, deposit types, and amounts of undiscovered nonfuel mineral resources remaining in the world? What is the availability of global geologic, mineral deposit, and mineral-exploration information? How can mineral-resource assessments be used to address economic and environmental issues? Presentations will include overviews of assessment methods used in previous national and other small-scale assessments of large regions as well as resulting assessment products and their uses.

    Study Design Descriptive study. Background Professional meetings, such as the American Physical Therapy Association's (APTA's) Combined Sections Meeting (CSM), provide forums for sharing information. However, it was reported that only one-quarter of orthopaedic and sports physical therapy abstracts presented at the CSM between 2000 and 2004 went on to full-text publication. This low conversion rate raises a number of concerns regarding the full dissemination of work within the profession. Objectives The purpose of this study was to determine the full-text publication rate of work presented in abstract form at subsequent CSMs and investigate factors influencing the rate. Methods A systematic search was undertaken to locate full-text publications of orthopaedic and sports physical therapy abstracts presented at CSMs between 2005 and 2011. Eligible publications were published within 5 years following abstract presentation. The influences of year of abstract presentation, APTA section, presentation type, institution of origin, study design, and study significance were assessed. Results Over one-third (38.6%) of presented abstracts progressed to full-text publication. Odds of full-text publication increased if the abstract was presented as a platform presentation, originated from a doctorate-granting institution, reported findings of an experimental study, or reported a statistically significant finding. Conclusion The full-text publication rate for orthopaedic and sports physical therapy abstracts presented at recent CSMs has increased by over 50% compared to that reported for the preceding period. The rate is now in the range of that reported in comparable clinical disciplines, demonstrating important progress in the full dissemination of work within the profession.

    To review abstracts presented at five consecutive meetings of the European College of Veterinary Ophthalmologists (ECVO), and identify abstract characteristics that affect the probability of their publication in peer-reviewed journals. An online search was conducted for peer-reviewed publications (PRPs) stemming from abstracts from five ECVO meetings (2008-2012). Time to publication and journal were noted. Effects of ocular tissue/discipline, species, type of presentation and study, funding acknowledgment and affiliation, professional qualifications, and nationality of the first and last authors on probability of publication were analyzed. Of presented abstracts, 29% (87/299) were published as PRPs in Veterinary Ophthalmology (n = 50), other veterinary journals (n = 22), and nonveterinary journals (n = 15). During the 5 years studied, there was no significant difference between the impact factor of Veterinary Ophthalmology and the 25 other journals in which PRPs were published (P = 0.369). Median time to PRP acceptance or publication was 468 days. Independent variables most significant in determining the probability of PRP were oral presentation (P = 0.002), resident authorship (P < 0.0001), and species (P = 0.002), with food animal abstracts having the highest odds ratio. Ocular tissue/discipline (P = 0.13) and type of study (P = 0.33) did not affect publication probability. Funding acknowledgment (P = 0.02), author nationality (P = 0.02), and academic affiliation (P = 0.04) were also significant factors. Publication rate of ECVO abstracts is lower, but time to publication is similar, compared with most biomedical meetings. © 2017 American College of Veterinary Ophthalmologists.

    Complex organic molecules (COMs) have been observed not only in the hot cores surrounding low- and high-mass protostars, but also in cold dark clouds. Therefore, it is interesting to understand how such species can be formed without the presence of embedded energy sources. We present new laboratory experiments on the low-temperature solid state formation of three complex molecules - methyl formate (HC(O)OCH3), glycolaldehyde (HC(O)CH2OH) and ethylene glycol (H2C(OH)CH2OH) - through recombination of free radicals formed via H-atom addition and abstraction reactions at different stages in the CO→H2CO→CH3OH hydrogenation network at 15 K. The experiments extend previous CO hydrogenation studies and aim at resembling the physical-chemical conditions typical of the CO freeze-out stage in dark molecular clouds, when H2CO and CH3OH form by recombination of accreting CO molecules and H-atoms on ice grains. We confirm that H2CO, once formed through CO hydrogenation, not only yields CH3OH through ongoing H-atom addition reactions, but is also subject to H-atom-induced abstraction reactions, yielding CO again. In a similar way, H2CO is also formed in abstraction reactions involving CH3OH. The dominant methanol H-atom abstraction product is expected to be CH2OH, while H-atom additions to H2CO should at least partially proceed through CH3O intermediate radicals. The occurrence of H-atom abstraction reactions in ice mantles leads to more reactive intermediates (HCO, CH3O and CH2OH) than previously thought, when assuming sequential H-atom addition reactions only. This enhances the probability to form COMs through radical-radical recombination without the need of UV photolysis or cosmic rays as external triggers.

    The Israel Society for Neuroscience (ISFN) was founded in 1993 by a group of Israeli leading scientists conducting research in the area of neurobiology. The primary goal of the society was to promote and disseminate the knowledge and understanding acquired by its members, and to strengthen interactions between them. Since then, the society holds its annual meeting every year in Eilat during the month of December. At these annual meetings the senior Israeli neurobiologists, their teams, and their graduate students, as well as foreign scientists and students, present their recent research findings in platform and poster presentations. The meeting also offers the opportunity for the researchers to exchange information with each other, often leading to the initiation of collaborative studies. Both the number of members of the society and of those participating in the annual meeting is constantly increasing, and it is anticipated that this year about 600 scientists will convene at the Princess Hotel in Eilat, Israel.

    In Public Health, a thorough review of abstract quality evaluations and the publication history of studies presented at scientific meetings has never been conducted. To analyse the long-term outcome of quality abstracts submitted to conferences of Italian Society of Hygiene and Public Health (SItI) from 2005 to 2007, we conducted a second analysis of previously published material aiming to estimate full-text publication rate of high quality abstract presented at Italian public health meetings, and to identify predictors of full-text publication. The search was undertaken through scientific databases and search engines and through the web sites of the major Italian journals of Public Health. For each publication confirmed as a full text paper, the journal name, impact factor, year of publication, gender of the first author, type of study design, characteristics of the results and sample size were collected. The overall publication rate of the abstracts presented is 23.5%; most of the papers were published in Public Health journals (average impact factor: 3.007). Non universitary affiliation had resulted in a lower probability of publication, while some of the Conference topics had predisposed the studies to an increased likelihood of publication as well as poster form presentation. The method presented in this study provides a good framework for the evaluation of the scientific evidence. The findings achieved should be taken into consideration by the Scientific Societies during the contributions selection phase, with the aim of achieving a continuous improvement of work quality. In the future, it would be interesting to survey the abstract authors to identify reasons for unpublished data.

    The purpose of this study was to find out the rate of peer-reviewed publication of full papers of abstracts presented at the annual meeting of the Oral and Maxillofacial Surgery Society of Turkey, and to identify the time taken for publication, subspecialty, and study design. All abstracts accepted for presentation at the meetings in 2007-12 were identified from the books of abstracts, and evidence of publication was sought from PubMed and Google Scholar. The following variables were evaluated: publication rate, type of presentation (oral or poster), time to publication, subspecialty, study design, name of the journal in which the paper was published, impact factor of the journal, author affiliation, change in number of authors and origin of the study. A total of 1322 abstracts were presented between 2007 and 2012. Of these, 246 (19%) were subsequently published in peer-reviewed journals, including 110/390 oral presentations (28%) and 136/932 poster presentations (15%). Oral presentations were more likely to be published than poster presentations (p=0.000). The mean (SD) time from presentation to publication was 17 (15) months. Anatomical presentations had the highest publication rate (8/11), whereas orthognathic surgery had the lowest (5/67, 7%). Technical notes (5/9) and animal studies (32/70, 46%) were the most common types of publication. Only 246 of the 1322 abstracts (19%) were subsequently published as full papers, which is lower than previously reported in oral and maxillofacial surgery.

    The rate of conversion of abstracts presented at scientific meetings into peer-reviewed published manuscripts is an important metric for medical societies, because it facilitates translation of scientific knowledge into practice. We determined the rate and predictors of conversion of scientific abstracts presented at the Canadian Cardiovascular Congress (CCC) from 2006 to 2010 into peer-reviewed article publications within 2 years of their initial presentation. Using a previously validated computer algorithm, we searched the International Statistical Institute Web of Science to identify peer-reviewed full manuscript publications of these abstracts. A multivariable logistic regression was used to identify independent factors associated with successful publication. From 2006 to 2010, 3565 abstracts were presented at the CCC. Overall 24.1% of presented abstracts were published within 2 years of the conference. Mean impact factor for publications was 5.2 (range, 0.4-53.2). The type of presentation (for poster vs oral; odds ratio, 0.71; 95% confidence interval, 0.60-0.83; P < 0.001) and category of presentation (P < 0.001) were significantly associated with successful publication. Late breaking abstracts and those related to cancer and clinical sciences were more likely to be published, compared with prevention, vascular biology, and pediatrics. In conclusion, the publication rate at the CCC is only marginally lower than that reported for large international North American and European cardiology conferences (30.6%). Efforts should focus on several identified barriers to improve conversion of abstracts to full report publication. Copyright © 2013 Canadian Cardiovascular Society. Published by Elsevier Inc.

    : Many studies are presented at scientific meetings and are summarized in abstract form prior to their full-length publication. Publication rates of these studies may be an indicator in judging their quality. To determine the rate at which studies reported in an abstract form are subsequently published in full length and identify factors associated with publication success. : All abstracts presented at the 25th Annual Meeting of SMDM in October 2003 were reviewed and assessed for subsequent publication in peer-reviewed journals through December 31, 2007. For each abstract we recorded the presenting author's affiliation, presentation mode, and country of origin. For published articles, we recorded the publication date, type of journal, and the journal's impact factor. We calculated the mean and median time from conference presentation to publication using a Kaplan-Meier survival analysis. : Of 239 presented abstracts, 64 (27%) were subsequently published in full-length, including 39% of podium, and 20% of poster presentations (P = 0.002). Mean and median times from presentation to publication were 20.5 and 19.0 months, respectively. There was no significant difference in mean publication lag for podium and poster presentations. : A significant proportion of studies presented at the SMDM meeting are not published in full length. This failure to publish is substantially higher as compared with findings from other medical and biomedical meetings. A further study is needed to explore the reasons for this low publication rate and to compare the fate of SMDM meeting abstracts to those of similar conferences.

  7. White-tailed deer browse on an invasive shrub with extended leaf phenology meets assumptions of an apparent competition hypothesis

    PubMed Central

    Martinod, Kylie L.

    2017-01-01

    Abstract It has been hypothesized that invasive plant species with extended leaf phenology (ELP) elevate generalist herbivore populations, increasing herbivory on native plants (apparent competition). This hypothesis assumes that consumption of the invasive is associated with periods of ELP, the invasive is a major component of the herbivore’s diet, and that it is more nutritious than native plants during periods of ELP. We tested these assumptions by estimating the proportion of the white-tailed deer diet comprised of Lonicera maackii, an invasive shrub with ELP, quantifying the seasonal pattern of deer browse on this invasive shrub, and comparing its nutritional quality to leafless woody stems. In the Miami University Natural Areas in southwest Ohio we quantified the frequency of leafy twigs of woody species 0.3–2.1 m high in three habitats (deciduous forest, Juniperus virginiana forest, and forest-field edge). Monthly we quantified deer browse on marked L. maackii twigs, and estimated the mass of leaf and stem tissue consumed with allometric relationships using diameter and length of unbrowsed twig portions. We estimated the percent of the annual deer diet comprised of L. maackii by dividing the sum of these estimates by the product of deer abundance (estimated by pellet-based distance sampling) and consumption estimates from the literature. Crude protein of L. maackii stems and leaves was determined by C:N analyser. In each habitat the frequency of L. maackii was greater than all other woody species combined. We estimated L. maackii comprised 14–47 % of the annual deer diet. Deer browsed L. maackii each month, but consumption was high in early spring and late summer. Crude protein of leafy twigs of L. maackii in early spring was 12.9 %, much higher than leafless twigs of native species on-site. These findings support the assumptions of the hypothesis that invasive plants with ELP impact native plants via deer-mediated apparent competition. PMID

    It is well known that Cu plays an important role in CdTe solar cell performance as a dopant. In this work, a finitedifference method is developed and used to simulate Cu diffusion in CdTe solar cells. In the simulations, which are done on a twodimensional (2D) domain, the CdTe is assumed to be polycrystalline, with the individual grains separated by grain boundaries. When used to fit experimental Cu concentration data, bulk and grain boundary diffusion coefficients and activation energies for CdTe can be extracted. In the past, diffusion coefficients have been typically obtained by fitting data to simple functional forms of limited validity. By doing full simulations, the simplifying assumptions used in those analytical models are avoided and diffusion parameters can thus be determined more accurately.

  3. Extended abstract: Partial row projection methods

    Bramley, R.; Lee, Y.

    1996-12-31

    Accelerated row projection (RP) algorithms for solving linear systems Ax = b are a class of iterative methods which in theory converge for any nonsingular matrix. RP methods are by definition ones that require finding the orthogonal projection of vectors onto the null space of block rows of the matrix. The Kaczmarz form, considered here because it has a better spectrum for iterative methods, has an iteration matrix that is the product of such projectors. Because straightforward Kaczmarz method converges slowly for practical problems, typically an outer CG acceleration is applied. Definiteness, symmetry, or localization of the eigenvalues, of the coefficient matrix is not required. In spite of this robustness, work has generally been limited to structured systems such as block tridiagonal matrices because unlike many iterative solvers, RP methods cannot be implemented by simply supplying a matrix-vector multiplication routine. Finding the orthogonal projection of vectors onto the null space of block rows of the matrix in practice requires accessing the actual entries in the matrix. This report introduces a new partial RP algorithm which retains advantages of the RP methods.

    In this work, we report on developing 1D reaction-diffusion solver to understand the kinetics of p-type doping formation in CdTe absorbers and to shine some light on underlying causes of metastabilities observed in CdTe PV devices. Evolution of intrinsic and Cu-related defects in CdTe solar cell has been studied in time-space domain self-consistently with free carrier transport and Poisson equation. Resulting device performance was simulated as a function of Cu diffusion anneal time showing pronounced effect the evolution of associated acceptor and donor states can cause on device characteristics. Although 1D simulation has intrinsic limitations when applied to poly-crystalline films, the results suggest strong potential of the approach in better understanding of the performance and metastabilities of CdTe photovoltaic device.

    2012-01-01

    Imagine that you are tasked to help a project improve their testing effort. In a realistic scenario it will quickly become clear, that having an impact is diffcult. First of all, it will likely be a challenge to suggest an alternative approach which is significantly more automated and/or more effective than current practice. The reality is that an average software system has a complex input/output behavior. An automated testing approach will have to auto-generate test cases, each being a pair (i; o) consisting of a test input i and an oracle o. The test input i has to be somewhat meaningful, and the oracle o can be very complicated to compute. Second, even in case where some testing technology has been developed that might improve current practice, it is then likely difficult to completely change the current behavior of the testing team unless the technique is obviously superior and does everything already done by existing technology. So is there an easier way to incorporate formal methods-based approaches than the full edged test revolution? Fortunately the answer is affirmative. A relatively simple approach is to benefit from possibly already existing logging infrastructure, which after all is part of most systems put in production. A log is a sequence of events, generated by special log recording statements, most often manually inserted in the code by the programmers. An event can be considered as a data record: a mapping from field names to values. We can analyze such a log using formal methods, for example checking it against a formal specification. This separates running the system for analyzing its behavior. It is not meant as an alternative to testing since it does not address the important in- put generation problem. However, it offers a solution which testing teams might accept since it has low impact on the existing process. A single person might be assigned to perform such log analysis, compared to the entire testing team changing behavior.

    The low dose symposium thoughtfully addressed controversy of risk from low dose radiation exposure, hormesis and radon therapy. The stem cell symposium cogently considered the role of DNA damage and repair in hematopoietic stem cells underlying aging and malignancy and provocatively presented evidence that stem cells may have distinct morphologies and replicative properties, as well as special roles in cancer initiation. In the epigenetics symposium, studies illustrated the long range interaction of epigenetic mechanisms, the roles of CTCF and BORIS in region/specific regulation of epigenetic processes, the impact of DNA damage on epigenetic processes as well as links between epigenetic mechanisms and early nutrition and bystander effects. This report shows the agenda and abstracts for this symposium.

    Despite the enormous personal and social cost Of substance abuse, there is very little knowledge with respect to the mechanisms by which these drugs produce addiction as well as to the mechanisms of toxicity. Similarly, there is a lack of effective therapeutic intervention to treat the drug abusers. In this respect, nuclear medicine could contribute significantly by helping to gather information using brain imaging techniques about mechanisms of drug addiction which, in turn, could help design better therapeutic interventions, and by helping in the evaluation and diagnosis of organ toxicity from the use of drugs of abuse. This volume contains six short descriptions of presentations made at the 18th Meeting of the American College of Nuclear Physicians -- DOE Day: Substance Abuse and Nuclear Medicine.

  15. http://www.agu.org/meetings/fm09/program/abstract_submissions.php Precipitation trends in California: Rainfall is becoming wetter with heavier rain events

    NASA Astrophysics Data System (ADS)

    Ladochy, S.; Killam, D.; Bui, A.; Patzert, W. C.; Willis, J. K.; Ramirez, P.

    2009-12-01

    Recent U.S. climate data and climate model scenarios indicate that precipitation is increasing and heavy precipitation events are more numerous in most areas of the United States through the 20th Century. California records show some similarities to these results, but also some differences. By analyzing daily precipitation records from 20 California stations having continuous data from at least 1925 to present, we derived linear trends for both annual rainfall totals and for number of heavy rainfall events. Results vary with regions of the state. Annual precipitation amounts generally increased over the period of record for central and northern California, but did not change significantly in southern California. Year to year variability is large, especially to the drier south. The greatest percentage increases occur in the central region. All stations show a marked Pacific influence with ENSO and PDO signals showing prominently in the rainfall record, especially in southern California. Many stations, but not all, exhibit a shift towards higher daily rainfall amounts. They show decreases in the proportion of light rains and increases in moderate to heavy rains. Most stations indicate some change in seasonal rainfall totals. Increases in seasonal totals are found mostly in winter while decreases are occurring in fall. Spring trends are more varied and inconclusive. With the state in a long period of drought, the implications of these results for California water resources are unclear. While the state depends on the northern portions to meet much of the water demands, warmer temperatures may negate any precipitation increases through greater evaporation. Also negating the prospect of more water is the increased potential for flooding, particularly to the north.

  16. Binding abstract concepts.

    PubMed

    Singh, Tarini; Frings, Christian; Moeller, Birte

    2017-07-22

    Binding theories assume that a stimulus and the response made to it are bound together in an event file (Hommel et al., Behav Brain Sci 24(05):849-937, 2001). Such bindings can occur even after single encounters. If the stimulus or parts of its features are repeated within the time frame in which the event file is still intact, the previously integrated response is retrieved. Stimulus-response binding can exist at a perceptual, conceptual or a response selection level (Henson et al., Trends Cogn Sci 18(7):376-384, 2014). The current experiments test whether the observed binding of concepts with responses can be extended from concrete to abstract concepts (detailedness) and whether abstract concepts can retrieve the previous response, in the absence of perceptual repetition. In the present experiment participants responded to a target feature (colour) while the detailedness of the stimulus was irrelevant to the task. The results showed a significant interaction of response relation and detailedness relation, even in the absence of perceptual repetition. This interaction is interpreted as evidence for response-retrieval due to abstract concept repetition. Thus, our data suggest a broader impact of binding mechanism on performance as even abstract concepts can be integrated into event-files and later modulate behaviour.

    (Abstract only) We are developing a system of robotic telescopes for automatic recognition of Supernovas as well as other transient events in collaboration with the Puckett Supernova Search Team. At the SAS2014 meeting, the discovery program, SNARE, was first described. Since then, it has been continuously improved to handle searches under a wide variety of atmospheric conditions. Currently, two telescopes are used to build a reference library while searching for PSN with a partial library. Since data is taken every night without clouds, we must deal with varying atmospheric and high background illumination from the moon. Software is configured to identify a PSN, reshoot for verification with options to change the run plan to acquire photometric or spectrographic data. The telescopes are 24-inch CDK24, with Alta U230 cameras, one in CA and one in NM. Images and run plans are sent between sites so the CA telescope can search while photometry is done in NM. Our goal is to find bright PSNs with magnitude 17.5 or less which is the limit of our planned spectroscopy. We present results from our first automated PSN discoveries and plans for PSN data acquisition.

    In the last few months the data holdings in the ADS have been considerably expanded. In the abstracts databases we have included over 50,000 abstracts from SPIE conference proceedings (provided by SPIE), a complete set of references for lunar and planetary sciences, and abstracts from recent Lunar and Planetary Institute sponsored conferences (both provided by the Lunar and Planetary Institute). We also extended our cooperation with the CDS in Strasbourg, France by providing a link to the list of objects that are in the SIMBAD database for each reference. The ADS article service now holds full-text articles for 20 years of the Astrophysical Journal Letters, the Astronomical Journal, and the Publications of the Astronomical Society of the Pacific, and 5 years of the Astrophysical Journal on-line. The following journals are being processed and some may be on-line for this AAS meeting: Astrophysical Journal (1975-1989), Astronomy and Astrophysics, Proceedings of the Astronomical Society of Australia, Publications of the Astronomical Society of Japan, Revista Mexicana, Bulletin of the Astronomical Society of India, Obs. Reports of Skalnate Pleso, and Baltic Astronomy. We are now working with two scanning companies to speed up the scanning process and hope that by the end of the year we have all of these journals completely on-line for at least the period 1975 - 1995.

  17. Abstraction and Problem Reformulation

    NASA Technical Reports Server (NTRS)

    Giunchiglia, Fausto

    1992-01-01

    In work done jointly with Toby Walsh, the author has provided a sound theoretical foundation to the process of reasoning with abstraction (GW90c, GWS9, GW9Ob, GW90a). The notion of abstraction formalized in this work can be informally described as: (property 1), the process of mapping a representation of a problem, called (following historical convention (Sac74)) the 'ground' representation, onto a new representation, called the 'abstract' representation, which, (property 2) helps deal with the problem in the original search space by preserving certain desirable properties and (property 3) is simpler to handle as it is constructed from the ground representation by "throwing away details". One desirable property preserved by an abstraction is provability; often there is a relationship between provability in the ground representation and provability in the abstract representation. Another can be deduction or, possibly inconsistency. By 'throwing away details' we usually mean that the problem is described in a language with a smaller search space (for instance a propositional language or a language without variables) in which formulae of the abstract representation are obtained from the formulae of the ground representation by the use of some terminating rewriting technique. Often we require that the use of abstraction results in more efficient .reasoning. However, it might simply increase the number of facts asserted (eg. by allowing, in practice, the exploration of deeper search spaces or by implementing some form of learning). Among all abstractions, three very important classes have been identified. They relate the set of facts provable in the ground space to those provable in the abstract space. We call: TI abstractions all those abstractions where the abstractions of all the provable facts of the ground space are provable in the abstract space; TD abstractions all those abstractions wllere the 'unabstractions' of all the provable facts of the abstract space are

  18. Abstraction in mathematics.

    PubMed Central

    Ferrari, Pier Luigi

    2003-01-01

    Some current interpretations of abstraction in mathematical settings are examined from different perspectives, including history and learning. It is argued that abstraction is a complex concept and that it cannot be reduced to generalization or decontextualization only. In particular, the links between abstraction processes and the emergence of new objects are shown. The role that representations have in abstraction is discussed, taking into account both the historical and the educational perspectives. As languages play a major role in mathematics, some ideas from functional linguistics are applied to explain to what extent mathematical notations are to be considered abstract. Finally, abstraction is examined from the perspective of mathematics education, to show that the teaching ideas resulting from one-dimensional interpretations of abstraction have proved utterly unsuccessful.

    This report summarizes the presentations and discussions that took place at the Seventh Joint Meeting of the Korea–Japan Study Group of Prostate Cancer (K-J-CaP) and the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) held in Seoul, Korea, in September 2013. The original J-CaP and CaPSURE Joint Initiative has now been established since 2007 and since the initial collaboration between research teams in the United States (US) and Japan, the project has expanded to include several other Asian countries. The objective of the initiative is to analyze and compare data for prostate cancer patients in the participating countries, looking at similarities and differences in patient management and outcomes. Until now the focus has been primarily on data generated within J-CaP and CaPSURE, both large-scale, longitudinal, observational databases of prostate cancer patients in Japan and the US, respectively. This year’s meeting was hosted for the first time in Korea which has recently established its own national database–K-CaP–to add to the wealth of data generated by J-CaP and CaPSURE. As a newly-developed database, K-CaP has also provided a valuable ‘template’ for other countries, such as China and Indonesia, planning to establish their own national databases and this will ultimately allow greater opportunities for international data comparisons. A range of topics was discussed at this Seventh Joint Meeting including comparison of outcomes following androgen deprivation therapy or radical prostatectomy in patients with localized prostate cancer, the use of active surveillance as a treatment option and the triggers for intervention when employing this regimen, patient quality of life during treatment, the impact of comorbidities on outcomes, and a comparison of recent outcomes data between J-CaP and CaPSURE.

  1. Retrieval of abstract semantics.

    PubMed

    Noppeney, Uta; Price, Cathy J

    2004-05-01

    Behavioural and neuropsychological evidence suggests that abstract and concrete concepts might be represented, retrieved and processed differently in the human brain. Using fMRI, we demonstrate that retrieval of abstract relative to sensory-based semantics during synonym judgements increased activation in a left frontotemporal system that has been associated with semantic processing particularly at the sentence level. Since activation increases were observed irrespective of the degree of difficulty, we suggest that these differential activations might reflect a particular retrieval mechanism or strategy for abstract concepts. In contrast to sensory-based semantics, the meaning of abstract concepts is largely specified by their usage in language rather than by their relations to the physical world. Subjects might therefore generate an appropriate semantic sentential context to fully explore and specify the meaning of abstract concepts. Our results also explain why abstract semantics is vulnerable to left frontotemporal lesions.

    Owre, Sam; Shankar, Natarajan

    1997-01-01

    PVS (Prototype Verification System) is a general-purpose environment for developing specifications and proofs. This document deals primarily with the abstract datatype mechanism in PVS which generates theories containing axioms and definitions for a class of recursive datatypes. The concepts underlying the abstract datatype mechanism are illustrated using ordered binary trees as an example. Binary trees are described by a PVS abstract datatype that is parametric in its value type. The type of ordered binary trees is then presented as a subtype of binary trees where the ordering relation is also taken as a parameter. We define the operations of inserting an element into, and searching for an element in an ordered binary tree; the bulk of the report is devoted to PVS proofs of some useful properties of these operations. These proofs illustrate various approaches to proving properties of abstract datatype operations. They also describe the built-in capabilities of the PVS proof checker for simplifying abstract datatype expressions.

    The extended abstracts in this volume are summaries of the papers presented orally and as posters in the first V.E. McKelvey Forum on Mineral and Energy Resources, entitled "USGS Research on Mineral Resources-1985." The Forum has been established to improve communication between the USGS and the earth science community by presenting the results of current USGS research on nonrenewable resources in a timely fashion and by providing an opportunity for individuals from other organizations to meet informally with USGS scientists and managers. It is our hope that the McKelvey Forum will help to make USGS programs more responsive to the needs of the earth science community, particularly the mining and petroleum industries, and will foster closer cooperation between organizations and individuals.

    Clear, transparent, and sufficiently detailed abstracts of conferences and journal articles related to randomized controlled trials (RCTs) are important, because readers often base their assessment of a trial solely on information in the abstract. Here, we extend the CONSORT (Consolidated Standards of Reporting Trials) Statement to develop a minimum list of essential items, which authors should consider when reporting the results of a RCT in any journal or conference abstract. We generated a list of items from existing quality assessment tools and empirical evidence. A three-round, modified-Delphi process was used to select items. In all, 109 participants were invited to participate in an electronic survey; the response rate was 61%. Survey results were presented at a meeting of the CONSORT Group in Montebello, Canada, January 2007, involving 26 participants, including clinical trialists, statisticians, epidemiologists, and biomedical editors. Checklist items were discussed for eligibility into the final checklist. The checklist was then revised to ensure that it reflected discussions held during and subsequent to the meeting. CONSORT for Abstracts recommends that abstracts relating to RCTs have a structured format. Items should include details of trial objectives; trial design (e.g., method of allocation, blinding/masking); trial participants (i.e., description, numbers randomized, and number analyzed); interventions intended for each randomized group and their impact on primary efficacy outcomes and harms; trial conclusions; trial registration name and number; and source of funding. We recommend the checklist be used in conjunction with this explanatory document, which includes examples of good reporting, rationale, and evidence, when available, for the inclusion of each item. CONSORT for Abstracts aims to improve reporting of abstracts of RCTs published in journal articles and conference proceedings. It will help authors of abstracts of these trials provide the

    Christensen, J.

    1991-01-01

    Traditionally, abstraction in planning has been accomplished by either state abstraction or operator abstraction, neither of which has been fully automatic. We present a new method, predicate relaxation, for automatically performing state abstraction. PABLO, a nonlinear hierarchical planner, implements predicate relaxation. Theoretical, as well as empirical results are presented which demonstrate the potential advantages of using predicate relaxation in planning. We also present a new definition of hierarchical operators that allows us to guarantee a limited form of completeness. This new definition is shown to be, in some ways, more flexible than previous definitions of hierarchical operators. Finally, a Classical Truth Criterion is presented that is proven to be sound and complete for a planning formalism that is general enough to include most classical planning formalisms that are based on the STRIPS assumption.

    Tattooing involves the introduction of exogenous pigment into the dermis. Worldwide, tattoos are one of the most popular forms of permanent body art. In the Netherlands, 8-10% of the population older than 12 years old has a tattoo. A wide variety of cutaneous adverse effects can occur in tattoos, these can cause serious symptoms. However, recognition and appropriate knowledge of diagnosis and treatment is still frequently insufficient in many medical practitioners. The first case concerns a 57-year-old female, who developed an itching swelling in the red part of a tattoo on the left arm. Histology of a punch biopsy showed a pseudolymphomatous reaction. This plaque-like allergic reaction was successfully treated with intralesional injection of corticosteroids. Here we described four cases of cutaneous adverse reactions to tattoos. Allergic reactions in tattoos can present in a wide variety of clinical and histological patterns. The symptoms are often chronic itch and can appear weeks, months or years after placing the tattoo. Allergic reactions are uniformly manifested in one particular colour. Clinically, the reactions can present in a plaque-like, hyperkeratotic or rarely ulcerative or generalised reaction. In spite of changes to the compounds in tattoo inks, allergic reactions are still mostly observed to red ink. Treatment options are topical corticosteroids, intralesional injection of corticosteroids, laser treatment or dermatome shaving.

We note that this requirement set is not the same for individual (stand-alone) devices or for electronic health record systems, and we must take care to define system-level requirements rather than security goals for components. The requirements themselves build on each other such that it is difficult or impossible to eliminate any one of the requirements and still achieve high-level security goals. PMID:25599096

  16. Extended abstract: Managing disjunction for practical temporal reasoning

    NASA Technical Reports Server (NTRS)

    Boddy, Mark; Schrag, Bob; Carciofini, Jim

    1992-01-01

    One of the problems that must be dealt with in either a formal or implemented temporal reasoning system is the ambiguity arising from uncertain information. Lack of precise information about when events happen leads to uncertainty regarding the effects of those events. Incomplete information and nonmonotonic inference lead to situations where there is more than one set of possible inferences, even when there is no temporal uncertainty at all. In an implemented system, this ambiguity is a computational problem as well as a semantic one. In this paper, we discuss some of the sources of this ambiguity, which we will treat as explicit disjunction, in the sense that ambiguous information can be interpreted as defining a set of possible inferences. We describe the application of three techniques for managing disjunction in an implementation of Dean's Time Map Manager. Briefly, the disjunction is either: removed by limiting the expressive power of the system, or approximated by a weaker form of representation that subsumes the disjunction. We use a combination of these methods to implement an expressive and efficient temporal reasoning engine that performs sound inference in accordance with a well-defined formal semantics.

  18. An investigation of packet reordering in TCP traces (extended abstract)

    Recent research has highlighted the impact of packet reordering on network dynamics. Still, while much work has investigated the statistical properties of inter-packet arrival times of TCP traces, little effort has been devoted to obtaining a model of network traffic that incorporates sequence ID numbers as well. With the ultimate goal to develop such a joint model, they present results on the dynamics of packet reordering in a set of publicly available TCP traces recorded at the Network Research lab at UCLA. they investigate the scaling properties of the number of packet inversions. They propose a two-state model for the dynamics of sequence IDs based on pivots (defined as packets for which the received packet sequence has no gaps). This concept allows us to partition the trace into time epochs based on the presence or absence of reordering. Thys, they are able to identify and store patterns of reordering in the packet streams. Statistical tests provide a first-order validation of the model. Finally, they investigate the reordering patterns identified by their model from the standpoint of standard measures of presortedness of integer sequences. The methodology outlined in this paper enables regeneration of synthetic traces with inversion characteristics that are statistically similar to those of the original data. It is part of RESTORED, a network inference and analysis tool under development at Los Alamos National Laboratory.

  1. Symbolic LTL Compilation for Model Checking: Extended Abstract

    Rozier, Kristin Y.; Vardi, Moshe Y.

    2007-01-01

    In Linear Temporal Logic (LTL) model checking, we check LTL formulas representing desired behaviors against a formal model of the system designed to exhibit these behaviors. To accomplish this task, the LTL formulas must be translated into automata [21]. We focus on LTL compilation by investigating LTL satisfiability checking via a reduction to model checking. Having shown that symbolic LTL compilation algorithms are superior to explicit automata construction algorithms for this task [16], we concentrate here on seeking a better symbolic algorithm.We present experimental data comparing algorithmic variations such as normal forms, encoding methods, and variable ordering and examine their effects on performance metrics including processing time and scalability. Safety critical systems, such as air traffic control, life support systems, hazardous environment controls, and automotive control systems, pervade our daily lives, yet testing and simulation alone cannot adequately verify their reliability [3]. Model checking is a promising approach to formal verification for safety critical systems which involves creating a formal mathematical model of the system and translating desired safety properties into a formal specification for this model. The complement of the specification is then checked against the system model. When the model does not satisfy the specification, model-checking tools accompany this negative answer with a counterexample, which points to an inconsistency between the system and the desired behaviors and aids debugging efforts.

  5. Metacognition and abstract reasoning.

    The nature of people's meta-representations of deductive reasoning is critical to understanding how people control their own reasoning processes. We conducted two studies to examine whether people have a metacognitive representation of abstract validity and whether familiarity alone acts as a separate metacognitive cue. In Study 1, participants were asked to make a series of (1) abstract conditional inferences, (2) concrete conditional inferences with premises having many potential alternative antecedents and thus specifically conducive to the production of responses consistent with conditional logic, or (3) concrete problems with premises having relatively few potential alternative antecedents. Participants gave confidence ratings after each inference. Results show that confidence ratings were positively correlated with logical performance on abstract problems and concrete problems with many potential alternatives, but not with concrete problems with content less conducive to normative responses. Confidence ratings were higher with few alternatives than for abstract content. Study 2 used a generation of contrary-to-fact alternatives task to improve levels of abstract logical performance. The resulting increase in logical performance was mirrored by increases in mean confidence ratings. Results provide evidence for a metacognitive representation based on logical validity, and show that familiarity acts as a separate metacognitive cue.

    2004-10-25

    The primary purpose of this model report is to develop abstractions for the response of engineered barrier system (EBS) components to seismic hazards at a geologic repository at Yucca Mountain, Nevada, and to define the methodology for using these abstractions in a seismic scenario class for the Total System Performance Assessment - License Application (TSPA-LA). A secondary purpose of this model report is to provide information for criticality studies related to seismic hazards. The seismic hazards addressed herein are vibratory ground motion, fault displacement, and rockfall due to ground motion. The EBS components are the drip shield, the waste package, and the fuel cladding. The requirements for development of the abstractions and the associated algorithms for the seismic scenario class are defined in ''Technical Work Plan For: Regulatory Integration Modeling of Drift Degradation, Waste Package and Drip Shield Vibratory Motion and Seismic Consequences'' (BSC 2004 [DIRS 171520]). The development of these abstractions will provide a more complete representation of flow into and transport from the EBS under disruptive events. The results from this development will also address portions of integrated subissue ENG2, Mechanical Disruption of Engineered Barriers, including the acceptance criteria for this subissue defined in Section 2.2.1.3.2.3 of the ''Yucca Mountain Review Plan, Final Report'' (NRC 2003 [DIRS 163274]).

    Gortais, Bernard

    2003-01-01

    In a given social context, artistic creation comprises a set of processes, which relate to the activity of the artist and the activity of the spectator. Through these processes we see and understand that the world is vaster than it is said to be. Artistic processes are mediated experiences that open up the world. A successful work of art expresses a reality beyond actual reality: it suggests an unknown world using the means and the signs of the known world. Artistic practices incorporate the means of creation developed by science and technology and change forms as they change. Artists and the public follow different processes of abstraction at different levels, in the definition of the means of creation, of representation and of perception of a work of art. This paper examines how the processes of abstraction are used within the framework of the visual arts and abstract painting, which appeared during a period of growing importance for the processes of abstraction in science and technology, at the beginning of the twentieth century. The development of digital platforms and new man-machine interfaces allow multimedia creations. This is performed under the constraint of phases of multidisciplinary conceptualization using generic representation languages, which tend to abolish traditional frontiers between the arts: visual arts, drama, dance and music.

  15. EBS Radionuclide Transport Abstraction

    SciTech Connect

    R. Schreiner

    2001-06-27

    The purpose of this work is to develop the Engineered Barrier System (EBS) radionuclide transport abstraction model, as directed by a written development plan (CRWMS M&O 1999a). This abstraction is the conceptual model that will be used to determine the rate of release of radionuclides from the EBS to the unsaturated zone (UZ) in the total system performance assessment-license application (TSPA-LA). In particular, this model will be used to quantify the time-dependent radionuclide releases from a failed waste package (WP) and their subsequent transport through the EBS to the emplacement drift wall/UZ interface. The development of this conceptual model will allow Performance Assessment Operations (PAO) and its Engineered Barrier Performance Department to provide a more detailed and complete EBS flow and transport abstraction. The results from this conceptual model will allow PA0 to address portions of the key technical issues (KTIs) presented in three NRC Issue Resolution Status Reports (IRSRs): (1) the Evolution of the Near-Field Environment (ENFE), Revision 2 (NRC 1999a), (2) the Container Life and Source Term (CLST), Revision 2 (NRC 1999b), and (3) the Thermal Effects on Flow (TEF), Revision 1 (NRC 1998). The conceptual model for flow and transport in the EBS will be referred to as the ''EBS RT Abstraction'' in this analysis/modeling report (AMR). The scope of this abstraction and report is limited to flow and transport processes. More specifically, this AMR does not discuss elements of the TSPA-SR and TSPA-LA that relate to the EBS but are discussed in other AMRs. These elements include corrosion processes, radionuclide solubility limits, waste form dissolution rates and concentrations of colloidal particles that are generally represented as boundary conditions or input parameters for the EBS RT Abstraction. In effect, this AMR provides the algorithms for transporting radionuclides using the flow geometry and radionuclide concentrations determined by other

  16. Interpreting Abstract Interpretations in Membership Equational Logic

    NASA Technical Reports Server (NTRS)

    Fischer, Bernd; Rosu, Grigore

    2001-01-01

    We present a logical framework in which abstract interpretations can be naturally specified and then verified. Our approach is based on membership equational logic which extends equational logics by membership axioms, asserting that a term has a certain sort. We represent an abstract interpretation as a membership equational logic specification, usually as an overloaded order-sorted signature with membership axioms. It turns out that, for any term, its least sort over this specification corresponds to its most concrete abstract value. Maude implements membership equational logic and provides mechanisms to calculate the least sort of a term efficiently. We first show how Maude can be used to get prototyping of abstract interpretations "for free." Building on the meta-logic facilities of Maude, we further develop a tool that automatically checks and abstract interpretation against a set of user-defined properties. This can be used to select an appropriate abstract interpretation, to characterize the specified loss of information during abstraction, and to compare different abstractions with each other.

  18. An Abstract Data Interface

    NASA Astrophysics Data System (ADS)

    Allan, D. J.

    The Abstract Data Interface (ADI) is a system within which both abstract data models and their mappings on to file formats can be defined. The data model system is object-oriented and closely follows the Common Lisp Object System (CLOS) object model. Programming interfaces in both C and \\fortran are supplied, and are designed to be simple enough for use by users with limited software skills. The prototype system supports access to those FITS formats most commonly used in the X-ray community, as well as the Starlink NDF data format. New interfaces can be rapidly added to the system---these may communicate directly with the file system, other ADI objects or elsewhere (e.g., a network connection).

    Current techniques for validating and verifying program changes often consider the entire program, even for small changes, leading to enormous V&V costs over a program s lifetime. This is due, in large part, to the use of syntactic program techniques which are necessarily imprecise. Building on recent advances in symbolic execution of heap manipulating programs, in this paper, we develop techniques for performing abstract semantic differencing of program behaviors that offer the potential for improved precision.

    Abstract Objective To examine trends in family medicine training at a time when substantial pedagogic change is under way, focusing on factors that relate to extended family medicine training. Design Aggregate-level secondary data analysis based on the Canadian Post-MD Education Registry. Setting Canada. Participants All Canadian citizens and permanent residents who were registered in postgraduate family medicine training programs within Canadian faculties of medicine from 1995 to 2013. Main outcome measures Number and proportion of family medicine residents exiting 2-year and extended (third-year and above) family medicine training programs, as well as the types and numbers of extended training programs offered in 2015. Results The proportion of family medicine trainees pursuing extended training almost doubled during the study period, going from 10.9% in 1995 to 21.1% in 2013. Men and Canadian medical graduates were more likely to take extended family medicine training. Among the 5 most recent family medicine exit cohorts (from 2009 to 2013), 25.9% of men completed extended training programs compared with 18.3% of women, and 23.1% of Canadian medical graduates completed extended training compared with 13.6% of international medical graduates. Family medicine programs vary substantially with respect to the proportion of their trainees who undertake extended training, ranging from a low of 12.3% to a high of 35.1% among trainees exiting from 2011 to 2013. Conclusion New initiatives, such as the Triple C Competency-based Curriculum, CanMEDS–Family Medicine, and Certificates of Added Competence, have emerged as part of family medicine education and credentialing. In acknowledgment of the potential effect of these initiatives, it is important that future research examine how pedagogic change and, in particular, extended training shapes the care family physicians offer their patients. As part of that research it will be important to measure the breadth and uptake of

  4. Abstraction Augmented Markov Models.

    High accuracy sequence classification often requires the use of higher order Markov models (MMs). However, the number of MM parameters increases exponentially with the range of direct dependencies between sequence elements, thereby increasing the risk of overfitting when the data set is limited in size. We present abstraction augmented Markov models (AAMMs) that effectively reduce the number of numeric parameters of k(th) order MMs by successively grouping strings of length k (i.e., k-grams) into abstraction hierarchies. We evaluate AAMMs on three protein subcellular localization prediction tasks. The results of our experiments show that abstraction makes it possible to construct predictive models that use significantly smaller number of features (by one to three orders of magnitude) as compared to MMs. AAMMs are competitive with and, in some cases, significantly outperform MMs. Moreover, the results show that AAMMs often perform significantly better than variable order Markov models, such as decomposed context tree weighting, prediction by partial match, and probabilistic suffix trees.

    The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment (TSPA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data. The transport model considers advective transport and diffusive transport

    RESUME is a system that performs temporal abstraction of time-stamped data. RESUME is based on a model of three temporal-abstraction mechanisms: point temporal abstraction (a mechanism for abstracting values of several parameters into a value of another parameter); temporal inference (a mechanism for inferring sound logical conclusions over a single interval or two meeting intervals); and temporal interpolation (a mechanism for bridging nonmeeting temporal intervals). Making explicit the knowledge required for temporal abstraction supports the acquisition of that knowledge. PMID:1482852

    Drift seepage refers to flow of liquid water into repository emplacement drifts, where it can potentially contribute to degradation of the engineered systems and release and transport of radionuclides within the drifts. Because of these important effects, seepage into emplacement drifts is listed as a ''principal factor for the postclosure safety case'' in the screening criteria for grading of data in Attachment 1 of AP-3.15Q, Rev. 2, ''Managing Technical Product Inputs''. Abstraction refers to distillation of the essential components of a process model into a form suitable for use in total-system performance assessment (TSPA). Thus, the purpose of this analysis/model is to put the information generated by the seepage process modeling in a form appropriate for use in the TSPA for the Site Recommendation. This report also supports the Unsaturated-Zone Flow and Transport Process Model Report. The scope of the work is discussed below. This analysis/model is governed by the ''Technical Work Plan for Unsaturated Zone Flow and Transport Process Model Report'' (CRWMS M&O 2000a). Details of this activity are in Addendum A of the technical work plan. The original Work Direction and Planning Document is included as Attachment 7 of Addendum A. Note that the Work Direction and Planning Document contains tasks identified for both Performance Assessment Operations (PAO) and Natural Environment Program Operations (NEPO). Only the PAO tasks are documented here. The planning for the NEPO activities is now in Addendum D of the same technical work plan and the work is documented in a separate report (CRWMS M&O 2000b). The Project has been reorganized since the document was written. The responsible organizations in the new structure are the Performance Assessment Department and the Unsaturated Zone Department, respectively. The work plan for the seepage abstraction calls for determining an appropriate abstraction methodology, determining uncertainties in seepage, and providing

    The first Subwog 12-D Tritium Technology Meeting was held at the Westinghouse Savannah River Site during the week of May 21, 1990. Subwog 12-D was created as a subwog of JOWOG 12 to address the need to understand tritium applications throughout the entire weapons complex. This includes weapons related concerns, but is primarily intended to cover tritium production and handling, environmental, safety and health issues, compatibility with materials in general; and facility design, commissioning and decommissioning activities. Tritium technology issues discussed included the physical and chemical properties, kinetics, storage, reservoir loading techniques, isotope exchange, radiolysis/aging, process and handling technology, compatibility, purification and filtering, analysis, monitoring methods, function testing, packaging and shipping, environmental and operational safety, facility design and safety, glovebox atmosphere clean-up systems, glovebox/facility decommissioning, tritium production target materials, and tritium recovery. This document provides a collection of most of the unclassified extended abstracts and abstracts presented at Subwog 12-D.

I had met Mark at NEAF in 2012 when he was walking the floor demonstrating the telescope. We held meetings with three libraries, the St. Louis County Library system, the St. Louis Public Library system and an independent library in Kirkwood, Missouri. The response was overwhelming! SLCL responded with a request for ten telescopes and SLPL asked for five. We did our first build in October, 2014 and placed a total of eighteen telescopes. Since that time, SLAS has placed a total of eighty-eight telescopes in library systems around the St. Louis Metro area, expanding into neighboring counties and across the river in Illinois. In this talk, I will discuss how to approach this project and put it in place in your libraries!

    The increasing scale-up of fast pyrolysis in North America and Europe, as well as the exploration and expansion of markets for the energy use of biocrude oils that now needs to take place, suggested that it was timely to convene an international meeting on the properties and combustion behavior of these oils. A common understanding of the state-of-the-art and technical and other challenges which need to be met during the commercialization of biocrude fuel use, can be achieved. The technical issues and understanding of combustion of these oils are rapidly being advanced through R&D in the United States, Canada, Europe and Scandinavia. It is obvious that for the maximum economic impact of biocrude, it will be necessary to have a common set of specifications so that oils can be used interchangeably with engines and combustors which require minimal modification to use these renewable fuels. Fundamental and applied studies being pursued in several countries are brought together in this workshop so that we can arrive at common strategies. In this way, both the science and the commercialization are advanced to the benefit of all, without detracting from the competitive development of both the technology and its applications. This United States-Canada-Finland collaboration has led to the two and one half day specialists meeting at which the technical basis for advances in biocrude development is discussed. The goal is to arrive at a common agenda on issues that cross national boundaries in this area. Examples of agenda items are combustion phenomena, the behavior of trace components . of the oil (N, alkali metals), the formation of NO{sub x}, in combustion, the need for common standards and environmental safety and health issues in the handling, storage and transportation of biocrudes.

    A strength of model checking is its ability to automate the detection of subtle system errors and produce traces that exhibit those errors. Given the high computational cost of model checking most researchers advocate the use of aggressive property-preserving abstractions. Unfortunately, the more aggressively a system is abstracted the more infeasible behavior it will have. Thus, while abstraction enables efficient model checking it also threatens the usefulness of model checking as a defect detection tool, since it may be difficult to determine whether a counter-example is feasible and hence worth developer time to analyze. We have explored several strategies for addressing this problem by extending an explicit-state model checker, Java PathFinder (JPF), to search for and analyze counter-examples in the presence of abstractions. We demonstrate that these techniques effectively preserve the defect detection ability of model checking in the presence of aggressive abstraction by applying them to check properties of several abstracted multi-threaded Java programs. These new capabilities are not specific to JPF and can be easily adapted to other model checking frameworks; we describe how this was done for the Bandera toolset.

    To provide guidance on writing congress abstracts for submission and how to increase the chance of acceptance. There is increasing competition for submitted abstracts to be accepted by scientific congresses. Because the facilities or size of a congress may be limited a selection process is often used based upon the quality of abstracts submitted. Accordingly, it is crucial for a researcher to prepare an abstract very carefully to ensure the best chance of acceptance. The approaches to preparing an abstract and the techniques for enhancing quality are reviewed. Suggestions and guidance are given to ensure the production of a well structured, informative and scientifically sound abstract.

  20. Extended antipaternalism

    2005-01-01

    Extended antipaternalism means the use of antipaternalist arguments to defend activities that harm (consenting) others. As an example, a smoker's right to smoke is often invoked in defence of the activities of tobacco companies. It can, however, be shown that antipaternalism in the proper sense does not imply such extended antipaternalism. We may therefore approve of Mill's antipaternalist principle (namely, that the only reason to interfere with someone's behaviour is to protect others from harm) without accepting activities that harm (consenting) others. This has immediate consequences for the ethics of public health. An antipaternalist need not refrain from interfering with activities such as the marketing of tobacco or heroin, boxing promotion, driving with unbelted passengers, or buying sex from "voluntary" prostitutes.

    (Abstract only) To the ancients, the Earth was the Universe, of a size to be crossed by a god in a day, by boat or chariot, and by humans in a lifetime. Thus an exoplanet would have been a multiverse. The ideas gradually separated over centuries, with gradual acceptance of a sun-centered solar system, the stars as suns likely to have their own planets, other galaxies beyond the Milky Way, and so forth. And whenever the community divided between "just one' of anything versus "many," the "manies" have won. Discoveries beginning in 1991 and 1995 have gradually led to a battalion or two of planets orbiting other stars, very few like our own little family, and to moderately serious consideration of even larger numbers of other universes, again very few like our own. I'm betting, however, on habitable (though not necessarily inhabited) exoplanets to be found, and habitable (though again not necessarily inhabited) universes. Only the former will yield pretty pictures.

    A sixteen-run, Resolution IV, fractional factorial screening design has been used to evaluate the relative significance of seven independent material and process variables for an electrically deposited commercial acrylic paint. A Resolution IV design was chosen so that variable interactions could be detected without any interference from the effects of the variables themselves. Because resource limitations did not permit use of a Resolution V design, the two-way interactions were confounded with one another in groups of three, which unfortunately made interpretation of the results more complicated. Each design point was replicated once and a pair of centerpoints were run at the beginning, in the middle and at the end of the design points. A total of 38 test panels were prepared. Independent variables used in this experiment were total charge, current density, mixer speed, silica content, crossover point, temperature and solids fraction. The magnitude of each independent variable's effect on the dependent response variables was estimated by fitting a first-order model with two-way interaction terms. Three-way interactions were assumed to be insignificant. Interaction confounding was eliminated by using the significance of the independent variables to determine which of the three possible interactions was significant. Data analysis was performed using the Bayes Plot option of the JMP statistics program from SAS Institute. Only effects with a posterior probability equal to or greater than 0.95 were considered to be significant. Response variables analyzed were weight deposited, film thickness, surface roughness and plating efficiency. Results of the analysis are summarized. The following conclusions were formulated from the analysis of this experiment: Centerpoint behavior brings shelf-stability of the aqueous paint baths into question; Interactions among the material and process variables are present and significant; The magnitudes of some interaction effects equal or exceed the magnitudes of some of the effects of the independent variables; Silica is detrimental to surface smoothness, interacts strongly with other variables, is hard to keep suspended in aqueous baths, and should be replaced with a liquid rheology control agent; and Because of the significance of two-way variable interactions, One-Variable-At-A-Time experiments with this material and process could lead to erroneous conclusions about variable effects.

  12. Abstraction of Drift Seepage

    J.T. Birkholzer

    2004-11-01

    This model report documents the abstraction of drift seepage, conducted to provide seepage-relevant parameters and their probability distributions for use in Total System Performance Assessment for License Application (TSPA-LA). Drift seepage refers to the flow of liquid water into waste emplacement drifts. Water that seeps into drifts may contact waste packages and potentially mobilize radionuclides, and may result in advective transport of radionuclides through breached waste packages [''Risk Information to Support Prioritization of Performance Assessment Models'' (BSC 2003 [DIRS 168796], Section 3.3.2)]. The unsaturated rock layers overlying and hosting the repository form a natural barrier that reduces the amount of water entering emplacement drifts by natural subsurface processes. For example, drift seepage is limited by the capillary barrier forming at the drift crown, which decreases or even eliminates water flow from the unsaturated fractured rock into the drift. During the first few hundred years after waste emplacement, when above-boiling rock temperatures will develop as a result of heat generated by the decay of the radioactive waste, vaporization of percolation water is an additional factor limiting seepage. Estimating the effectiveness of these natural barrier capabilities and predicting the amount of seepage into drifts is an important aspect of assessing the performance of the repository. The TSPA-LA therefore includes a seepage component that calculates the amount of seepage into drifts [''Total System Performance Assessment (TSPA) Model/Analysis for the License Application'' (BSC 2004 [DIRS 168504], Section 6.3.3.1)]. The TSPA-LA calculation is performed with a probabilistic approach that accounts for the spatial and temporal variability and inherent uncertainty of seepage-relevant properties and processes. Results are used for subsequent TSPA-LA components that may handle, for example, waste package corrosion or radionuclide transport.

    This Workshop consisted of a full-day meeting of the Working Group "Sterren met Uitgebreide Atmosferen" (SUA, Working Group Stars with Extended Atmospheres), a discussion group founded in 1979 by Kees de Jager, Karel van der Hucht and Pik Sin The. This loose association of astronomers and astronomy students working in the Dutch-speaking part of the Low Countries (The Netherlands and Flanders) organised at regular intervals one-day meetings at the Universities of Utrecht, Leiden, Amsterdam and Brussels. These meetings consisted of the presentation of scientific results by junior as well as senior members of the group, and by discussions between the participants. As such, the SUA meetings became a forum for the exchange of ideas, and for asking questions and advice in an informal atmosphere. Kees de Jager has been chairman of the WG SUA from the beginning in 1979 till today, as the leading source of inspiration. At the occasion of Prof. Kees de Jager's 80th birthday, we decided to collect the presented talks in written form as a Festschrift in honour of this well-respected and much beloved scientist, teacher and friend. The first three papers deal with the personality of Kees de Jager, more specifically with his role as a supervisor and mentor of young researchers and as a catalyst in the research work of his colleagues. And also about his remarkable role in the establishment of astronomy education and research at the University of Brussels. The next presentation is a very detailed review of solar research, a field in which Cees was prominently active for many years. Then follow several papers dealing with stars about which Kees is a true expert: massive stars and extended atmospheres.

In the current article, we examine power signals within interpersonal communication, exploring whether use of concrete versus abstract language is seen as a signal of power. Because power activates abstraction (e.g., Smith & Trope, 2006), perceivers may expect higher power individuals to speak more abstractly and therefore will infer that speakers who use more abstract language have a higher degree of power. Across a variety of contexts and conversational subjects in 7 experiments, participants perceived respondents as more powerful when they used more abstract language (vs. more concrete language). Abstract language use appears to affect perceived power because it seems to reflect both a willingness to judge and a general style of abstract thinking.

  15. Grounding Abstractness: Abstract Concepts and the Activation of the Mouth

    One key issue for theories of cognition is how abstract concepts, such as freedom, are represented. According to the WAT (Words As social Tools) proposal, abstract concepts activate both sensorimotor and linguistic/social information, and their acquisition modality involves the linguistic experience more than the acquisition of concrete concepts. We report an experiment in which participants were presented with abstract and concrete definitions followed by concrete and abstract target-words. When the definition and the word matched, participants were required to press a key, either with the hand or with the mouth. Response times and accuracy were recorded. As predicted, we found that abstract definitions and abstract words yielded slower responses and more errors compared to concrete definitions and concrete words. More crucially, there was an interaction between the target-words and the effector used to respond (hand, mouth). While responses with the mouth were overall slower, the advantage of the hand over the mouth responses was more marked with concrete than with abstract concepts. The results are in keeping with grounded and embodied theories of cognition and support the WAT proposal, according to which abstract concepts evoke linguistic-social information, hence activate the mouth. The mechanisms underlying the mouth activation with abstract concepts (re-enactment of acquisition experience, or re-explanation of the word meaning, possibly through inner talk) are discussed. To our knowledge this is the first behavioral study demonstrating with real words that the advantage of the hand over the mouth is more marked with concrete than with abstract concepts, likely because of the activation of linguistic information with abstract concepts.

    The preparation of a strong, convincing abstract is a necessary professional skill and prized art form for nurse scientists and clinical scholars. The power and the role of an abstract are often overlooked. Abstracts are used in a variety of scholarly forums including articles submitted for publication, research proposals, and responses to "calls for abstracts" for presentations at scientific conferences. The purpose of this article is to emphasize the highlights of the "art" rather than the "cookbook" details associated with preparing an abstract. Each of the critical stages of abstract development is explored-planning, drafting, reviewing, peer reviewing, editing, and packaging. Likewise, a few, hopefully helpful, hints on developing the six key elements-background, purpose, sample, methods, results, and implications-of the scientific abstract are given. Polishing, the essential skill of preparing an abstract, takes time and persistence and will pay off in the long run. The well-crafted abstract is an initial step in the process of getting research and scholarly pursuits noticed and accepted.

    The International Energy Agency Fossil Fuel Multiphase Flow Sciences Agreement has been in effect since 1986. The traditional mechanism for the effort has been information exchange, effected by the inclusion of scientists in annual Executive committee meetings, by exchange of reports and papers, and by visits of scientists to one another`s institutions. In a sequence of informal meetings and at the 1993 Executive committee meeting, held in Pittsburgh, US in March 1994, it was decided that more intensive interactions could be productive. A candidate for such interactions would be specific projects. Each of these would be initiated through a meeting of scientists in which feasibility of the particular project was decided, followed by relatively intense international co-operation in which the work would be done. This is a report of the first of these meetings. Official or unofficial representatives from Canada, italy, japan, mexico, the United Kingdom, and the US met in Albuquerque, New Mexico, US, to consider the subject Flows of Granular Materials in Complex Geometries. Representatives of several other countries expressed interest but were unable to attend this meeting. Sixteen lectures were given on aspects of this topic. It was decided that a co-operative effort was desirable and possible. The most likely candidate for the area of study would be flows in bins and hoppers. Each of the countries wishing to co-operate will pursue funding for its effort. This report contains extended abstracts of the sixteen presentations and a transcription of the final discussion.

  1. A grounded theory of abstraction in artificial intelligence.

    Zucker, Jean-Daniel

    2003-01-01

    In artificial intelligence, abstraction is commonly used to account for the use of various levels of details in a given representation language or the ability to change from one level to another while preserving useful properties. Abstraction has been mainly studied in problem solving, theorem proving, knowledge representation (in particular for spatial and temporal reasoning) and machine learning. In such contexts, abstraction is defined as a mapping between formalisms that reduces the computational complexity of the task at stake. By analysing the notion of abstraction from an information quantity point of view, we pinpoint the differences and the complementary role of reformulation and abstraction in any representation change. We contribute to extending the existing semantic theories of abstraction to be grounded on perception, where the notion of information quantity is easier to characterize formally. In the author's view, abstraction is best represented using abstraction operators, as they provide semantics for classifying different abstractions and support the automation of representation changes. The usefulness of a grounded theory of abstraction in the cartography domain is illustrated. Finally, the importance of explicitly representing abstraction for designing more autonomous and adaptive systems is discussed. PMID:12903672

    concepts ("freedom") differ from concrete ones ("cat"), as they do not have a bounded, identifiable, and clearly perceivable referent. The way in which abstract concepts are represented has recently become a topic of intense debate, especially because of the spread of the embodied approach to cognition. Within this framework concepts derive their meaning from the same perception, motor, and emotional systems that are involved in online interaction with the world. Most of the evidence in favor of this view, however, has been gathered with regard to concrete concepts. Given the relevance of abstract concepts for higher-order cognition, we argue that being able to explain how they are represented is a crucial challenge that any theory of cognition needs to address. The aim of this article is to offer a critical review of the latest theories on abstract concepts, focusing on embodied ones. Starting with theories that question the distinction between abstract and concrete concepts, we review theories claiming that abstract concepts are grounded in metaphors, in situations and introspection, and in emotion. We then introduce multiple representation theories, according to which abstract concepts evoke both sensorimotor and linguistic information. We argue that the most promising approach is given by multiple representation views that combine an embodied perspective with the recognition of the importance of linguistic and social experience. We conclude by discussing whether or not a single theoretical framework might be able to explain all different varieties of abstract concepts.

    Although infants and animals respond to the approximate number of elements in visual, auditory, and tactile arrays, only human children and adults have been shown to possess abstract numerical representations that apply to entities of all kinds (e.g., 7 samurai, seas, or sins). Do abstract numerical concepts depend on language or culture, or do they form a part of humans' innate, core knowledge? Here we show that newborn infants spontaneously associate stationary, visual-spatial arrays of 4-18 objects with auditory sequences of events on the basis of number. Their performance provides evidence for abstract numerical representations at the start of postnatal experience.

    This study was carried out to determine if the content of structured abstracts conforms with recommendations of the Ad Hoc Working Group for the critical appraisal of the medical literature as adopted by the Annals of Internal Medicine. The study design was a survey. All articles published in Annals of Internal Medicine in 1991, excluding editorials, case-reports, literature reviews, decision analysis, studies in medical education, descriptive studies of clinical and basic phenomena, and papers lacking a structured abstract, were studied. Of a total of 150 articles, 20 were excluded. The abstract and text of each article were assessed for the presence of the following items; patient selection criteria, statements concerning extrapolation of findings, need for further study, and whether or not the information should be used now. Number of refusers, drop outs and reason(s) for drop outs were assessed for intervention and prospective cohort studies only. Deficiencies of assessed items were noted in both abstracts and texts. For abstracts, patient selection criteria, numbers of refusers, number of drop outs and reason(s) for drop outs were reported in 44.6% (58/130), 3.1% (4/130), 16.9% (14/83) and 2.4% (2/83) respectively. These items were reported more frequently in the texts 87.7% (114/130), 9.2% (12/130), 60.2% (50/83) and 37.3% (31/83) respectively (p < 0.05). Statements concerning extrapolation of findings, need for further study and use of information now were also more frequent in texts than abstracts (p < 0.0001). A large number of structured abstracts published in the Annals of Internal Medicine in 1991, lack information recommended by the Ad Hoc Working Group. Our findings should not be extrapolated to other journals requiring structured abstracts.

  1. Spatial language and abstract concepts.

    What is the relationship between spatial language and abstract concepts? When people talk about abstract things that they can never see or touch, they often use spatial metaphors (e.g., a long vacation, a high price, a close friendship). According to theories of metaphorical mental representation, linguistic metaphors reflect underlying mental metaphors. Yet, behavioral experiments show that this is only one of the possible relationships between spatial metaphors in language and our spatial conceptualizations of abstract domains. In some cases, linguistic metaphors not only reflect speakers' thoughts, they also change those thoughts, such that people who use different linguistic metaphors rely on correspondingly different mental metaphors. Alternatively, spatial metaphors in language may reflect the way people conceptualize an abstract domain in some circumstances, but not in others. Finally, spatial language may reflect the way an abstract domain is typically conceptualized by some people, but not by others. There is no single relationship between spatial language and abstract concepts. Discovering whether (and under what conditions) a linguistic metaphor corresponds to a mental metaphor can illuminate the ways in which our interactions with the physical and social environment shape our mental lives.

  2. Modelling abstraction licensing strategies ahead of the UK's water abstraction licensing reform

    NASA Astrophysics Data System (ADS)

    Klaar, M. J.

    2012-12-01

    Within England and Wales, river water abstractions are licensed and regulated by the Environment Agency (EA), who uses compliance with the Environmental Flow Indicator (EFI) to ascertain where abstraction may cause undesirable effects on river habitats and species. The EFI is a percentage deviation from natural flow represented using a flow duration curve. The allowable percentage deviation changes with different flows, and also changes depending on an assessment of the sensitivity of the river to changes in flow (Table 1). Within UK abstraction licensing, resource availability is expressed as a surplus or deficit of water resources in relation to the EFI, and utilises the concept of 'hands-off-flows' (HOFs) at the specified flow statistics detailed in Table 1. Use of a HOF system enables abstraction to cease at set flows, but also enables abstraction to occur at periods of time when more water is available. Compliance at low flows (Q95) is used by the EA to determine the hydrological classification and compliance with the Water Framework Directive (WFD) for identifying waterbodies where flow may be causing or contributing to a failure in good ecological status (GES; Table 2). This compliance assessment shows where the scenario flows are below the EFI and by how much, to help target measures for further investigation and assessment. Currently, the EA is reviewing the EFI methodology in order to assess whether or not it can be used within the reformed water abstraction licensing system which is being planned by the Department for Environment, Food and Rural Affairs (DEFRA) to ensure the licensing system is resilient to the challenges of climate change and population growth, while allowing abstractors to meet their water needs efficiently, and better protect the environment. In order to assess the robustness of the EFI, a simple model has been created which allows a number of abstraction, flow and licensing scenarios to be run to determine WFD compliance using the

    2008-01-01

    The North American Menopause Society (NAMS) provides a forum through which researchers can present scientific abstracts. After presenting an abstract, the goal is to publish the research as a full-length article. The objective for this study was to determine the publication rate of abstracts presented at NAMS meetings. The PubMed database was searched for full-length, peer-reviewed publications, corresponding to the abstracts presented at the 1999 to 2003 NAMS meetings. When a full-length article was found, the title, authors, date of publication, and the journal were collected. Of the 661 abstracts presented at the five consecutive annual meetings, 253 (38.3%) have been published in peer-reviewed journals. The average time to publication was 2.0 +/- 1.5 years. The average time to publication for oral presentations was 1.7 +/- 1.3 years, and that for poster presentations was 2.0 +/- 1.5 years (P = 0.241). The publication rate of oral presentations was significantly greater than that of poster presentations (57.7% vs 36.5%; P < 0.003). Manuscripts were published in a total of 97 journals, with four (Menopause, Journal of Clinical Endocrinology and Metabolism, Climacteric, and Maturitas) accounting for 38.3% of the publications. The percentage of abstracts published by NAMS is within the range and within a similar time frame compared with other scientific meetings. Oral presentations are more likely to be rapidly published and may therefore be of higher interest and clinical relevance along with sound methodology and results. Menopause contained the most manuscripts, demonstrating a possible preference of submission to the Society's journal.

    The Interfacing Microbiology and Biotechnology Conference was attended by over 100 faculty, post-docs, students, and research scientists from the US, Europe, and Latin America. The conference successfully stimulated communication and the dissemination of knowledge among scientists involved in basic and applied research. The focus of the conference was on microbial physiology and genetics and included sessions on C1 metabolism, archaeal metabolism, proteases and chaperones, gene arrays, and metabolic engineering. The meeting provided the setting for in-depth discussions between scientists who are internationally recognized for their research in these fields. The following objectives were met: (1) The promotion of interaction and future collaborative projects among scientists involved in basic and applied research which incorporates microbial physiology, genetics, and biochemistry; (2) the facilitation of communication of new research findings through seminars, posters, and abstracts; (3 ) the stimulation of enthusiasm and education among participants including graduate and undergraduate students.

    -Polanyi plots, calculated bond dissociation enthalpies (BDHs) correlate linearly with the standard enthalpy of activation (Δ(⧧)H°298), allowing estimation of the enthalpy barrier for reaction of NH2 with other hydrocarbons in future work. Finally, we develop six sets of the generalized Arrhenius rate parameters for H abstractions from different C-H bond types. These parameters extend the application of the present results to any noncyclic hydrocarbon interacting with the NH2 radical.

  6. Modelling Metamorphism by Abstract Interpretation

    NASA Astrophysics Data System (ADS)

    Dalla Preda, Mila; Giacobazzi, Roberto; Debray, Saumya; Coogan, Kevin; Townsend, Gregg M.

    Metamorphic malware apply semantics-preserving transformations to their own code in order to foil detection systems based on signature matching. In this paper we consider the problem of automatically extract metamorphic signatures from these malware. We introduce a semantics for self-modifying code, later called phase semantics, and prove its correctness by showing that it is an abstract interpretation of the standard trace semantics. Phase semantics precisely models the metamorphic code behavior by providing a set of traces of programs which correspond to the possible evolutions of the metamorphic code during execution. We show that metamorphic signatures can be automatically extracted by abstract interpretation of the phase semantics, and that regular metamorphism can be modelled as finite state automata abstraction of the phase semantics.

    2003-01-01

    work offers evidence that distributed planning agents can greatly reduce communication costs by reasoning at abstract levels. While it is intuitive that improved search can reduce communication in such cases, there are other decisions about how to communicate plan information that greatly affect communication costs. This paper identifies cases independent of search where communicating at multiple levels of abstraction can exponentially decrease costs and where it can exponentially add costs. We conclude with a process for determining appropriate levels of communication based on characteristics of the domain.

  9. Abstraction and natural language semantics.

    PubMed Central

    Kayser, Daniel

    2003-01-01

    According to the traditional view, a word prototypically denotes a class of objects sharing similar features, i.e. it results from an abstraction based on the detection of common properties in perceived entities. I explore here another idea: words result from abstraction of common premises in the rules governing our actions. I first argue that taking 'inference', instead of 'reference', as the basic issue in semantics does matter. I then discuss two phenomena that are, in my opinion, particularly difficult to analyse within the scope of traditional semantic theories: systematic polysemy and plurals. I conclude by a discussion of my approach, and by a summary of its main features. PMID:12903662

    Various types of scientific abstracts are selected and presented at meetings and listed in abstract books. Recently, a systematic review has shown that 45% of 30,000 abstracts were published in a journal. The aim of this study was to determine the features of abstracts selected to be presented at a EULAR meeting (2008) and the corresponding publication rates. The EULAR 2008 Abstract Book was extracted, presented abstracts were assessed, their publication status was checked, and features related with publication rate were determined. The publication status of abstracts as of January 20, 2011, was verified using PubMed. A total of 1,732 abstracts were assessed. Median publication duration was 13 (range: 0 to 31) months. Most of the abstracts (N=339) were of multi-national origin. Sixty seven percent of abstracts were clinical and 563 (33%) abstracts were preclinical. We found that 601 of all abstracts (34.7%) had been published in a journal, and most of were published in a rheumatology journal. Fifty-seven percent of published abstracts were in journals with an impact factor higher than 4. The publication rate was correlated with presentation type, number of centers involved, trial design, and number of patients enrolled. We found that the publication rate of EULAR 2008 abstracts at 30 months was approximately 35%. This is a high rate compared to a previously published systematic review that investigated the publication rate of studies initially presented as abstracts in medical meetings, which reported the publication rate at 24 and 36 months as 20.7% and 28.1%, respectively. More than half of the published abstracts were accepted by high-impact journals. Presentation type, number of centers, trial design, and enrolled patient numbers were all correlated with the rate of publication.

    Development of an extended test range, with range instrumentation providing continuous vehicle communications, is required to flight-test the X-33, a scaled version of a reusable launch vehicle. The extended test range provides vehicle communications coverage from California to landing at Montana or Utah. This paper provides an overview of the approaches used to meet X-33 program requirements, including using multiple ground stations, and methods to reduce problems caused by reentry plasma radio frequency blackout. The advances used to develop the extended test range show other hypersonic and access-to-space programs can benefit from the development of the extended test range.

  12. A "how-to" guide in preparing abstracts and poster presentations.

    Boullata, Joseph I; Mancuso, Carissa E

    2007-12-01

    The preparation of an abstract or poster to share information from a project or case report with colleagues is a professional goal for many nutrition support practitioners. This paper provides an approach to help practitioners prepare an abstract for submission and subsequently a poster for presentation at a meeting. A nutrition support question that required collecting and evaluating information, or a unique patient case or case series, can serve as the focus of an abstract and subsequent poster. The professional meeting selected should be appropriate for the abstract topic, and the authors should closely adhere to the organization's abstract submission guidelines. The well-prepared abstract will then serve as the outline for the poster content; the visual aspect of the poster is also important to effectively communicate the information to colleagues at the meeting. Adequate time is required to prepare both the abstract and the poster in order to fittingly reflect the value of the information. Efforts in preparing the abstract will be worthwhile once the abstract has been accepted by reviewers for a poster session at the meeting. Likewise, the effort in preparing the poster in advance allows the presenter to enjoy the poster session and discuss the project with colleagues.

    2013-01-01

    We examined the influence of affective priming on the appreciation of abstract artworks using an evaluative priming task. Facial primes (showing happiness, disgust or no emotion) were presented under brief (Stimulus Onset Asynchrony, SOA = 20 ms) and extended (SOA = 300 ms) conditions. Differences in aesthetic liking for abstract paintings depending on the emotion expressed in the preceding primes provided a measure of the priming effect. The results showed that, for the extended SOA, artworks were liked more when preceded by happiness primes and less when preceded by disgust primes. Facial expressions of happiness, though not of disgust, exerted similar effects in the brief SOA condition. Subjective measures and a forced-choice task revealed no evidence of prime awareness in the suboptimal condition. Our results are congruent with findings showing that the affective transfer elicited by priming biases evaluative judgments, extending previous research to the domain of aesthetic appreciation.

    Birch, David J. S.

    2012-08-01

    The multidisciplinary two-day Nano Meets Spectroscopy (NMS) event was held at the National Physical Laboratory (NPL), Teddington, UK, in September 2011. The event was planned from the outset to be at the interface of several areas—in particular, spectroscopy and nanoscience, and to bring together topics and people with different approaches to achieving common goals in biomolecular science. Hence the meeting cut across traditional boundaries and brought together researchers using diverse techniques, particularly fluorescence and Raman spectroscopy. Despite engaging common problems, these techniques are frequently seen as mutually exclusive with the two communities rarely interacting at conferences. The meeting was widely seen to have lived up to its billing in good measure. It attracted the maximum capacity of ~120 participants, including 22 distinguished speakers (9 from outside the UK), over 50 posters and a vibrant corporate exhibition comprising 10 leading instrument companies and IOP Publishing. The organizers were Professor David Birch (Chair), Dr Karen Faulds and Professor Duncan Graham of the University of Strathclyde, Professor Cait MacPhee of the University of Edinburgh and Dr Alex Knight of NPL. The event was sponsored by the European Science Foundation, the Institute of Physics, the Royal Society of Chemistry, NPL and the Scottish Universities Physics Alliance. The full programme and abstracts are available at http://sensor.phys.strath.ac.uk/nms/program.php. The programme was quite ambitious in terms of the breadth and depth of scope. The interdisciplinary and synergistic concept of 'X meets Y' played well, cross-fertilization between different fields often being a source of inspiration and progress. Fluorescence and Raman spectroscopy provided the core, but the meeting had little repetition and also attracted contributions on more specialist techniques such as CARS, super-resolution, single molecule and chiral methods. In terms of application the

  19. Object Classification via Planar Abstraction

    NASA Astrophysics Data System (ADS)

    Oesau, Sven; Lafarge, Florent; Alliez, Pierre

    2016-06-01

    We present a supervised machine learning approach for classification of objects from sampled point data. The main idea consists in first abstracting the input object into planar parts at several scales, then discriminate between the different classes of objects solely through features derived from these planar shapes. Abstracting into planar shapes provides a means to both reduce the computational complexity and improve robustness to defects inherent to the acquisition process. Measuring statistical properties and relationships between planar shapes offers invariance to scale and orientation. A random forest is then used for solving the multiclass classification problem. We demonstrate the potential of our approach on a set of indoor objects from the Princeton shape benchmark and on objects acquired from indoor scenes and compare the performance of our method with other point-based shape descriptors.

    NASA Technical Reports Server (NTRS)

    Butler, Ricky W.; Munoz, Cesar A.

    2006-01-01

    This paper presents a new planning language that is more abstract than most existing planning languages such as the Planning Domain Definition Language (PDDL) or the New Domain Description Language (NDDL). The goal of this language is to simplify the formal analysis and specification of planning problems that are intended for safety-critical applications such as power management or automated rendezvous in future manned spacecraft. The new language has been named the Abstract Plan Preparation Language (APPL). A translator from APPL to NDDL has been developed in support of the Spacecraft Autonomy for Vehicles and Habitats Project (SAVH) sponsored by the Explorations Technology Development Program, which is seeking to mature autonomy technology for application to the new Crew Exploration Vehicle (CEV) that will replace the Space Shuttle.

  4. Groundwater abstraction pollution risk assessment.

    PubMed

    Lytton, L; Howe, S; Sage, R; Greenaway, P

    2003-01-01

    A generic groundwater pollution risk assessment methodology has been developed to enable the evaluation and ranking of the potential risk of pollution to groundwater abstractions. The ranking can then be used to prioritise risk management or mitigation procedures in a robust and quantifiable framework and thus inform business investment decisions. The risk assessment consider the three components of the pollution transport model: source-pathway-receptor. For groundwater abstractions these correspond to land use (with associated pollutants and shallow subsurface characteristics), aquifer and the abstraction borehole. An hierarchical approach was chosen to allow the risk assessment to be successfully carried out with different quality data for different parts of the model. The 400-day groundwater protection zone defines the catchment boundary that form the spatial limit of the land use audit for each receptor. A risk score is obtained for each land use (potential pollution source) within the catchment. These scores are derived by considering the characteristics (such as load, persistence and toxicity) of all pollutants pertaining to each land use, their on-site management and the potential for the unsaturated subsurface to attenuate their effects in the event of a release. Risk scores are also applied to the aquifer characteristics (as pollutant pathway) and to the abstraction borehole (as pollutant receptor). Each risk score is accompanied by an uncertainty score which provides a guide to the confidence in the data used to compile the risk assessment. The application of the methodology has highlighted a number of problems in this type of work and results of initial case studies are being used to trial alternative scoring methods and a more simplified approach to accelerate the process of pollution risk assessment.

    The objective of this study was to identify factors associated with the conversion of scientific abstracts to publications in peer-reviewed journals. This was a retrospective study of abstracts presented by members of the Massachusetts General Hospital Department of Oral and Maxillofacial Surgery between 2000 and 2010. Predictor variables were categorized as abstract- or author-specific. The outcome variable was conversion of an abstract presented at a meeting to a published manuscript. Descriptive, bivariate, and multiple regression statistics were computed. P < 0.05 was significant. The sample was composed of 122 abstracts presented at meetings. Ninety abstracts (73.8%) were published in a peer-reviewed literature within 5 years of presentation. The mean time between presentation to publication was 21.9 ± 17.3 months (median, 19.0 months; range, 0-99 months). In bivariate analyses, study design, number of prior publications by the presenting author, and number of prior publications by the senior author were associated with time to publication (P < 0.06). In a multiple Cox proportional hazards model, higher levels of evidence (hazard ratio, 1.2; 95% confidence interval, 1.04-1.3; P = 0.006) and volume of prior publications by the senior author (hazard ratio, 1.007; 95% confidence interval, 1.003-1.011; P < 0.001) were associated with shorter publication times. Time to publication of scientific abstracts is associated with study quality, prior research experience by the presenting author, and senior author identity and experience.

  12. Abstract encoding of auditory objects in cortical activity patterns.

    PubMed

    Giordano, Bruno L; McAdams, Stephen; Zatorre, Robert J; Kriegeskorte, Nikolaus; Belin, Pascal

    2013-09-01

    The human brain is thought to process auditory objects along a hierarchical temporal "what" stream that progressively abstracts object information from the low-level structure (e.g., loudness) as processing proceeds along the middle-to-anterior direction. Empirical demonstrations of abstract object encoding, independent of low-level structure, have relied on speech stimuli, and non-speech studies of object-category encoding (e.g., human vocalizations) often lack a systematic assessment of low-level information (e.g., vocalizations are highly harmonic). It is currently unknown whether abstract encoding constitutes a general functional principle that operates for auditory objects other than speech. We combined multivariate analyses of functional imaging data with an accurate analysis of the low-level acoustical information to examine the abstract encoding of non-speech categories. We observed abstract encoding of the living and human-action sound categories in the fine-grained spatial distribution of activity in the middle-to-posterior temporal cortex (e.g., planum temporale). Abstract encoding of auditory objects appears to extend to non-speech biological sounds and to operate in regions other than the anterior temporal lobe. Neural processes for the abstract encoding of auditory objects might have facilitated the emergence of speech categories in our ancestors.

    This viewgraph presentation reviews the concept of the Operating System Abstraction Layer (OSAL) and its benefits. The OSAL is A small layer of software that allows programs to run on many different operating systems and hardware platforms It runs independent of the underlying OS & hardware and it is self-contained. The benefits of OSAL are that it removes dependencies from any one operating system, promotes portable, reusable flight software. It allows for Core Flight software (FSW) to be built for multiple processors and operating systems. The presentation discusses the functionality, the various OSAL releases, and describes the specifications.

    Varpio, Lara; Amiel, Jonathan; Richards, Boyd F

    2016-09-01

    The ability to write a competitive research conference abstract is an important skill for medical educators. A compelling and concise abstract can convince peer reviewers, conference selection committee members, and conference attendees that the research described therein is worthy for inclusion in the conference program and/or for their attendance in the meeting. This AMEE Guide is designed to help medical educators write research conference abstracts that can achieve these outcomes. To do so, this Guide begins by examining the rhetorical context (i.e. the purpose, audience, and structure) of research conference abstracts and then moves on to describe the abstract selection processes common to many medical education conferences. Next, the Guide provides theory-based information and concrete suggestions on how to write persuasively. Finally, the Guide offers some writing tips and some proofreading techniques that all authors can use. By attending to the aspects of the research conference abstract addressed in this Guide, we hope to help medical educators enhance this important text in their writing repertoire.

  1. Abstraction of Seepage into Drifts

    2000-09-26

    A total-system performance assessment (TSPA) for a potential nuclear-waste repository requires an estimate of the amount of water that might contact waste. This paper describes the model used for part of that estimation in a recent TSPA for the Yucca Mountain site. The discussion is limited to estimation of how much water might enter emplacement drifts; additional considerations related to flow within the drifts, and how much water might actually contact waste, are not addressed here. The unsaturated zone at Yucca Mountain is being considered for the potential repository, and a drift opening in unsaturated rock tends to act as a capillary barrier and divert much of the percolating water around it. For TSPA, the important questions regarding seepage are how many waste packages might be subjected to water flow and how much flow those packages might see. Because of heterogeneity of the rock and uncertainty about the future (how the climate will evolve, etc.), it is not possible to predict seepage amounts or locations with certainty. Thus, seepage is treated as a stochastic quantity in TSPA simulations, with the magnitude and spatial distribution of seepage sampled from uncertainty distributions. The distillation of the essential components of process modeling into a form suitable for use in TSPA simulations is referred to as abstraction. In the following sections, seepage process models and abstractions will be summarized and then some illustrative results are presented.

    2013-08-01

    This paper shows that classifying shapes is a tool useful in nonphotorealistic rendering (NPR) from photographs. Our classifier inputs regions from an image segmentation hierarchy and outputs the "best" fitting simple shape such as a circle, square, or triangle. Other approaches to NPR have recognized the benefits of segmentation, but none have classified the shape of segments. By doing so, we can create artwork of a more abstract nature, emulating the style of modern artists such as Matisse and other artists who favored shape simplification in their artwork. The classifier chooses the shape that "best" represents the region. Since the classifier is trained by a user, the "best shape" has a subjective quality that can over-ride measurements such as minimum error and more importantly captures user preferences. Once trained, the system is fully automatic, although simple user interaction is also possible to allow for differences in individual tastes. A gallery of results shows how this classifier contributes to NPR from images by producing abstract artwork.

  3. Onconephrology abstracts and publication trends: time to collaborate.

    PubMed

    2015-10-01

    Onconephrology is an emerging subspecialty of nephrology. The American Society of Nephrology(ASN) created a forum dedicated to the field of onconephrology in 2011 to improve collaborative care for cancer patients with kidney disease. In this article, we review the ASN Kidney Week abstracts that were related to onconephrology. There has been an increase in the number of onconephrology-related abstracts at ASN over last 3 years. But only one-fifth of abstracts that were onconephrology related in ASN were published in peer review journals. Clinical Kidney Journal (CKJ) has seen an increase in onconephrology publications in the last 3 years. Most were case reports or review articles. The more widespread use of the keyword 'onconephrology' in all such manuscripts may facilitate the search for onconephrology research papers. To advance the field, CKJ has now created an onconephrology subheading for manuscript categorization. We also propose that conference organizers of ASN and other kidney-related society meeting such as International Society of Nephrology, National Kidney Foundation and European Dialysis and Transplantation Association have a separate onconephrology abstract category. Randomized controlled trials in a subspecialty like onconephrology can only be possible when there is collaboration amongst nephrologists and cancer physicians from cancer centers around the world that interact and share research ideas at international meetings.

    (Abstract only) This is the tale of my continuing journey transforming from a visual to a CCD photometrist. It is my hope that sharing my experiences will help and encourage others to consider taking the same path. It has been hard, but fun; a wonderful opportunity as a newly retired physician to expand my horizons. However, my brain did have to make the switch from Biology to Physics. The major barrier that concerned me was cost, but change itself was also a challenge. Other issues included dealing with the complexity of technical systems and a myriad of details. My solution was to be patient and think small to insure success and then build upon all those little victories. The pedagogical component of this project was critical as well. It began with a good mentor and continued via networking with other members at meetings, taking CHOICE courses, and most importantly: practice, practice, practice. Each plateau suggested many new possibilities. I think “The Force” is now with me! The adventure continues.

    2017-08-01

    We aimed to determine the publication rate for abstracts presented at the International Meeting for Simulation in Healthcare (IMSH) and the time between abstract presentation and publication. We also aimed to describe the study features influencing subsequent publication and the relationship between these features and journal impact factors (IFs). All types of accepted abstracts from the 2012 and 2013 IMSH were reviewed. We extracted the following data from each abstract in duplicate: presentation format, subject, type of scholarship, research method, study design, outcome measure, number of institutions in authorship group, and number of study sites. PubMed and Google Scholar were searched (January 1, 2012 to August 1, 2016) using the names of the first, second, and last author for comparison with abstracts. Journal of publication and IF were recorded. Data were summarized with descriptive statistics. Bivariate and multivariate analysis was performed to explore the association between publication status and other variables. Of 541 abstracts, 22% (119/541) were published with a median time to publication of 16 months (interquartile range = 8.525), ranging from 0 to 43 months. The study characteristics associated with a greater likelihood of publication were the following: research-type abstract, quantitative studies, randomized trials, studies with patient or healthcare-related outcomes, multiple institutions represented in authorship group, and multicenter studies. Studies with multiple institutions in authorship group and multicenter studies were published in higher IF journals (P < 0.05). The publication rate of 22% for abstracts presented at IMSH is low, indicative of the relatively new nature of simulation-based research in healthcare.

  7. Abstract Expression Grammar Symbolic Regression

    NASA Astrophysics Data System (ADS)

    Korns, Michael F.

    This chapter examines the use of Abstract Expression Grammars to perform the entire Symbolic Regression process without the use of Genetic Programming per se. The techniques explored produce a symbolic regression engine which has absolutely no bloat, which allows total user control of the search space and output formulas, which is faster, and more accurate than the engines produced in our previous papers using Genetic Programming. The genome is an all vector structure with four chromosomes plus additional epigenetic and constraint vectors, allowing total user control of the search space and the final output formulas. A combination of specialized compiler techniques, genetic algorithms, particle swarm, aged layered populations, plus discrete and continuous differential evolution are used to produce an improved symbolic regression sytem. Nine base test cases, from the literature, are used to test the improvement in speed and accuracy. The improved results indicate that these techniques move us a big step closer toward future industrial strength symbolic regression systems.

  8. Abstraction Planning in Real Time

    When a planning agent works in a complex, real-world domain, it is unable to plan for and store all possible contingencies and problem situations ahead of time. The agent needs to be able to fall back on an ability to construct plans at run time under time constraints. This thesis presents a method for planning at run time that incrementally builds up plans at multiple levels of abstraction. The plans are continually updated by information from the world, allowing the planner to adjust its plan to a changing world during the planning process. All the information is represented over intervals of time, allowing the planner to reason about durations, deadlines, and delays within its plan. In addition to the method, the thesis presents a formal model of the planning process and uses the model to investigate planning strategies. The method has been implemented, and experiments have been run to validate the overall approach and the theoretical model.

    The development of computer science has produced a vast number of machine architectures, programming languages, and compiler technologies. The cross product of these three characteristics defines the spectrum of previous and present data representation methodologies. With regard to computer networks, the uniqueness of these methodologies presents an obstacle when disparate host environments are to be interconnected. Interoperability within a heterogeneous network relies upon the establishment of data representation commonality. The International Standards Organization (ISO) is currently developing the abstract syntax notation one standard (ASN.1) and the basic encoding rules standard (BER) that collectively address this problem. When used within the presentation layer of the open systems interconnection reference model, these two standards provide the data representation commonality required to facilitate interoperability. The details of a compiler that was built to automate the use of ASN.1 and BER are described. From this experience, insights into both standards are given and potential problems relating to this development effort are discussed.

  11. Reconciling Urgency and Variable Abstraction in a Hybrid Compositional Setting

    NASA Astrophysics Data System (ADS)

    van Beek, D. A.; Cuijpers, P. J. L.; Markovski, J.; Nadales Agut, D. E.; Rooda, J. E.

    The extension of timed formalisms to a hybrid setting with urgency, has been carried out in a rather straightforward manner, seemingly without difficulty. However, in this paper, we show that the combination of urgency with abstraction from continuous variables leads to undesired behavior. Abstraction from continuous variables ultimately leads to a timed system again, but with a much richer set of possible branching behaviors than a timed system that comprises only clocks. As it turns out, the formal definition of urgency, as defined for timed systems with clocks, does not fit our intuition of urgency anymore when applied to a timed system that is an abstraction of a hybrid system. Therefore, we propose to extend the formal semantics of timed and hybrid systems with guard trajectories. In this way, the continuous branching behavior introduced by hybrid systems remains visible even after abstraction from continuous variables. The practical applicability of the introduction of guard trajectories is illustrated by our revision of the structured operational semantics of the CIF language. The interplay between urgency and abstraction now adheres to our intuition, while compositionality with respect to urgency, variable abstraction, and parallel composition, is retained. In the future, symbolic elimination of urgency can be used to ensure that guard trajectories do not need to be actually calculated.

    2009-03-01

    To assess whether structured abstracts improved the sensitivity, precision and yield of retrieving clinical trials, using electronic searches, for example, MEDLINE, from dental journals. Retrospective, observational study. Clinical trials, published in six dental journals. Three that adopted structured abstracts (BDJ, CPJ, JO) and three that remained unchanged (JDR, EJO, AJODO) between January 1995 and December 1998 (extended to December 2002 for the JO). Adoption of a structured abstract format. Continued use of a non-structured abstract format. A combination of handsearching and the Cochrane Collaboration Oral Health Group's Trials Register and/or CENTRAL were used to identify randomised controlled trials (RCTs) and controlled clinical trials (CCTs) over the selected time period. MEDLINE was used to identify clinical trials in the selected journals over the same time period. There was no significant difference in the sensitivity or yield of clinical trial retrieval in journals with either abstract format over time. However, there was a significant increase in precision in journals that did not change their format (OR=4.96 (95% CI 1.18, 20.86) but not those that did. There was no significant difference in the sensitivity or yield of clinical trial retrieval either before or after the change in format or precision of retrieval before the change. However, in the later period, the precision of retrieval was significantly better in journals with unstructured abstracts compared to those with structured abstracts (OR=0.17 (95% CI 0.04, 0.7). The use of a structured abstract format does not improve the sensitivity, precision or yield of retrieval of clinical trials from MEDLINE.

  15. Attracting Girls into Physics (abstract)

    NASA Astrophysics Data System (ADS)

    Gadalla, Afaf

    2009-04-01

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

  16. An abstract approach to music.

    SciTech Connect

    Kaper, H. G.; Tipei, S.

    1999-04-19

    In this article we have outlined a formal framework for an abstract approach to music and music composition. The model is formulated in terms of objects that have attributes, obey relationships, and are subject to certain well-defined operations. The motivation for this approach uses traditional terms and concepts of music theory, but the approach itself is formal and uses the language of mathematics. The universal object is an audio wave; partials, sounds, and compositions are special objects, which are placed in a hierarchical order based on time scales. The objects have both static and dynamic attributes. When we realize a composition, we assign values to each of its attributes: a (scalar) value to a static attribute, an envelope and a size to a dynamic attribute. A composition is then a trajectory in the space of aural events, and the complex audio wave is its formal representation. Sounds are fibers in the space of aural events, from which the composer weaves the trajectory of a composition. Each sound object in turn is made up of partials, which are the elementary building blocks of any music composition. The partials evolve on the fastest time scale in the hierarchy of partials, sounds, and compositions. The ideas outlined in this article are being implemented in a digital instrument for additive sound synthesis and in software for music composition. A demonstration of some preliminary results has been submitted by the authors for presentation at the conference.

  17. Handedness shapes children's abstract concepts.

    PubMed

    Casasanto, Daniel; Henetz, Tania

    2012-03-01

    Can children's handedness influence how they represent abstract concepts like kindness and intelligence? Here we show that from an early age, right-handers associate rightward space more strongly with positive ideas and leftward space with negative ideas, but the opposite is true for left-handers. In one experiment, children indicated where on a diagram a preferred toy and a dispreferred toy should go. Right-handers tended to assign the preferred toy to a box on the right and the dispreferred toy to a box on the left. Left-handers showed the opposite pattern. In a second experiment, children judged which of two cartoon animals looked smarter (or dumber) or nicer (or meaner). Right-handers attributed more positive qualities to animals on the right, but left-handers to animals on the left. These contrasting associations between space and valence cannot be explained by exposure to language or cultural conventions, which consistently link right with good. Rather, right- and left-handers implicitly associated positive valence more strongly with the side of space on which they can act more fluently with their dominant hands. Results support the body-specificity hypothesis (Casasanto, 2009), showing that children with different kinds of bodies think differently in corresponding ways.

    This paper discusses the features of an annotation language that we believe to be essential for optimizing user-defined abstractions. These features should capture semantics of function, data, and object-oriented abstractions, express abstraction equivalence (e.g., a class represents an array abstraction), and permit extension of traditional compiler optimizations to user-defined abstractions. Our future work will include developing a comprehensive annotation language for describing the semantics of general object-oriented abstractions, as well as automatically verifying and inferring the annotated semantics.

    This paper contributes in two ways to the aims of this special issue on abstraction. The first is to show that there are compelling reasons motivating the use of abstraction in the purely computational realm of artificial intelligence. The second is to contribute to the overall discussion of the nature of abstraction by providing examples of the abstraction processes currently used in artificial intelligence. Although each type of abstraction is specific to a somewhat narrow context, it is hoped that collectively they illustrate the richness and variety of abstraction in its fullest sense. PMID:12903653

  4. Core foundations of abstract geometry.

    Dillon, Moira R; Huang, Yi; Spelke, Elizabeth S

    2013-08-27

    Human adults from diverse cultures share intuitions about the points, lines, and figures of Euclidean geometry. Do children develop these intuitions by drawing on phylogenetically ancient and developmentally precocious geometric representations that guide their navigation and their analysis of object shape? In what way might these early-arising representations support later-developing Euclidean intuitions? To approach these questions, we investigated the relations among young children's use of geometry in tasks assessing: navigation; visual form analysis; and the interpretation of symbolic, purely geometric maps. Children's navigation depended on the distance and directional relations of the surface layout and predicted their use of a symbolic map with targets designated by surface distances. In contrast, children's analysis of visual forms depended on the size-invariant shape relations of objects and predicted their use of the same map but with targets designated by corner angles. Even though the two map tasks used identical instructions and map displays, children's performance on these tasks showed no evidence of integrated representations of distance and angle. Instead, young children flexibly recruited geometric representations of either navigable layouts or objects to interpret the same spatial symbols. These findings reveal a link between the early-arising geometric representations that humans share with diverse animals and the flexible geometric intuitions that give rise to human knowledge at its highest reaches. Although young children do not appear to integrate core geometric representations, children's use of the abstract geometry in spatial symbols such as maps may provide the earliest clues to the later construction of Euclidean geometry.

  1. Sentence retrieval for abstracts of randomized controlled trials

    PubMed Central

    2009-01-01

    Background The practice of evidence-based medicine (EBM) requires clinicians to integrate their expertise with the latest scientific research. But this is becoming increasingly difficult with the growing numbers of published articles. There is a clear need for better tools to improve clinician's ability to search the primary literature. Randomized clinical trials (RCTs) are the most reliable source of evidence documenting the efficacy of treatment options. This paper describes the retrieval of key sentences from abstracts of RCTs as a step towards helping users find relevant facts about the experimental design of clinical studies. Method Using Conditional Random Fields (CRFs), a popular and successful method for natural language processing problems, sentences referring to Intervention, Participants and Outcome Measures are automatically categorized. This is done by extending a previous approach for labeling sentences in an abstract for general categories associated with scientific argumentation or rhetorical roles: Aim, Method, Results and Conclusion. Methods are tested on several corpora of RCT abstracts. First structured abstracts with headings specifically indicating Intervention, Participant and Outcome Measures are used. Also a manually annotated corpus of structured and unstructured abstracts is prepared for testing a classifier that identifies sentences belonging to each category. Results Using CRFs, sentences can be labeled for the four rhetorical roles with F-scores from 0.93–0.98. This outperforms the use of Support Vector Machines. Furthermore, sentences can be automatically labeled for Intervention, Participant and Outcome Measures, in unstructured and structured abstracts where the section headings do not specifically indicate these three topics. F-scores of up to 0.83 and 0.84 are obtained for Intervention and Outcome Measure sentences. Conclusion Results indicate that some of the methodological elements of RCTs are identifiable at the sentence

    Abstract abilities were studied in a sample of 34 individuals with severe TBI and a control group. The results indicate that TBI interferes with performance on tests requiring individuals to process information into new categories. There appears to be a dissociation between verbal abstract abilities and visual-perceptual abstract abilities. There is evidence that Goldstein and Sheerer's [1] postulate of a general 'abstract attitude' was at least partially correct. This attitude does not appear to be related to a general verbal ideational process, as dysphasic subjects were only deficient on a purely verbal abstract task.

  4. Abstract models of molecular walkers

    NASA Astrophysics Data System (ADS)

    Semenov, Oleg

    Recent advances in single-molecule chemistry have led to designs for artificial multi-pedal walkers that follow tracks of chemicals. The walkers, called molecular spiders, consist of a rigid chemically inert body and several flexible enzymatic legs. The legs can reversibly bind to chemical substrates on a surface, and through their enzymatic action convert them to products. We study abstract models of molecular spiders to evaluate how efficiently they can perform two tasks: molecular transport of cargo over tracks and search for targets on finite surfaces. For the single-spider model our simulations show a transient behavior wherein certain spiders move superdiffusively over significant distances and times. This gives the spiders potential as a faster-than-diffusion transport mechanism. However, analysis shows that single-spider motion eventually decays into an ordinary diffusive motion, owing to the ever increasing size of the region of products. Inspired by cooperative behavior of natural molecular walkers, we propose a symmetric exclusion process (SEP) model for multiple walkers interacting as they move over a one-dimensional lattice. We show that when walkers are sequentially released from the origin, the collective effect is to prevent the leading walkers from moving too far backwards. Hence, there is an effective outward pressure on the leading walkers that keeps them moving superdiffusively for longer times. Despite this improvement the leading spider eventually slows down and moves diffusively, similarly to a single spider. The slowdown happens because all spiders behind the leading spiders never encounter substrates, and thus they are never biased. They cannot keep up with leading spiders, and cannot put enough pressure on them. Next, we investigate search properties of a single and multiple spiders moving over one- and two-dimensional surfaces with various absorbing and reflecting boundaries. For the single-spider model we evaluate by how much the

    Background: There is a small body of research on improving the clarity of abstracts in general that is relevant to improving the clarity of abstracts of systematic reviews. Objectives: To summarize this earlier research and indicate its implications for writing the abstracts of systematic reviews. Method: Literature review with commentary on three main features affecting the clarity of abstracts: their language, structure, and typographical presentation. Conclusions: The abstracts of systematic reviews should be easier to read than the abstracts of medical research articles, as they are targeted at a wider audience. The aims, methods, results, and conclusions of systematic reviews need to be presented in a consistent way to help search and retrieval. The typographic detailing of the abstracts (type-sizes, spacing, and weights) should be planned to help, rather than confuse, the reader. PMID:11055300

    and will be ready for transferring soon. Petioles and internode tissue lacking bud meristem failed to produce any plantlets on any plates, however petioles developed large masses of undifferentiated callus tissue on SRM+2,4-D media. These callused pieces were then transferred to SRM+TDZ media, which resulted in even larger callus growth but no differentiation. All four selected plum lines were successfully transitioned into in vitro culture. Nodes from NASA-5 and NASA-10 lines produced the most numerous and well-developed leafy plantlets in vitro, while those from NASA-11 and Control-5 were generally smaller, slower growing and less numerous. The best method overall was to use young stem node tissue with buds, surface sterilize the pieces sequentially with 70 EtOH and 10 bleach, and then plate them onto SGM media. Future areas of study will include introducing additional genetic lines of GMO plum into in vitro culture, attempting to induce shoot growth in petiole callus tissue, testing methods (such as cold storage) that extend the time interval between transferring explants into new media, and testing viability of plantlets transferred from in vitro culture back to traditional pot culture.

    A description of three extended precision packages is presented along with three small conversion subroutines which can be used in conjunction with the extended precision packages. These extended packages represent software packages written in FORTRAN 4. They contain normalized or unnormalized floating point arithmetic with symmetric rounding and arbitrary mantissa lengths, and normalized floating point interval arithmetic with appropriate rounding. The purpose of an extended precision package is to enable the user to use and manipulate numbers with large decimal places as well as those with small decimal places where precision beyond double precision is required.

    TAMPR is a fully automatic transformation system based on syntactic rewrites. Our approach in a correctness proof is to map the transformation into an axiomatized mathematical domain where formal (and automated) reasoning can be performed. This mapping is accomplished via an extended denotational semantic paradigm. In this approach, the abstract notion of a program state is distributed between an environment function and a store function. Such a distribution introduces properties that go beyond the abstract state that is being modeled. The reasoning framework needs to be aware of these properties in order to successfully complete a correctness proof. This paper discusses some of our experiences in proving the correctness of TAMPR transformations.

    The extended Consolidated Standards of Reporting Trials (CONSORT) Statement for Abstracts was developed to improve the quality of reports of randomized controlled trials (RCTs) because readers often base their assessment of a trial solely on the abstract. To date, few data exist regarding whether it has achieved this goal. We evaluated the extent of adherence to the CONSORT for Abstract statement for quality of reports on RCT abstracts by four high-impact general medical journals. A descriptive analysis of published RCT abstracts in The New England Journal of Medicine (NEJM), The Lancet, The Journal of American Medical Association (JAMA), and the British Medical Journal (BMJ) in the year 2010 was conducted by two reviewers, independently extracting data from a MEDLINE/PubMed search. We identified 271 potential RCT abstracts meeting our inclusion criteria. More than half of the abstracts identified the study as randomized in the title (58.7%; 159/271), reported the specific objective/hypothesis (72.7%; 197/271), described participant eligibility criteria with settings for data collection (60.9%; 165/271), detailed the interventions for both groups (90.8%; 246/271), and clearly defined the primary outcome (94.8%; 257/271). However, the methodological quality domains were inadequately reported: allocation concealment (11.8%; 32/271) and details of blinding (21.0%; 57/271). Reporting the primary outcome results for each group was done in 84.1% (228/271). Almost all of the abstracts reported trial registration (99.3%; 269/271), whereas reports of funding and of harm or side effects from the interventions were found in only 47.6% (129/271) and 42.8% (116/271) of the abstracts, respectively. These findings show inconsistencies and non-adherence to the CONSORT for abstract guidelines, especially in the methodological quality domains. Improvements in the quality of RCT reports can be expected by adhering to existing standards and guidelines as expressed by the CONSORT group.

    Sterken, Christiaan; Aspaas, Per Pippin

    2013-06-01

    On 2-3 June 2012, the University of Tromsoe hosted a conference about the cultural and scientific history of the transits of Venus. The conference took place in Tromsoe for two very specific reasons. First and foremost, the last transit of Venus of this century lent itself to be observed on the disc of the Midnight Sun in this part of Europe during the night of 5 to 6 June 2012. Second, several Venus transit expeditions in this region were central in the global enterprise of measuring the scale of the solar system in the eighteenth century. The site of the conference was the Nordnorsk Vitensenter (Science Centre of Northern Norway), which is located at the campus of the University of Tromsoe. After the conference, participants were invited to either stay in Tromsoe until the midnight of 5-6 June, or take part in a Venus transit voyage in Finnmark, during which the historical sites Vardoe, Hammerfest, and the North Cape were to be visited. The post-conference program culminated with the participants observing the transit of Venus in or near Tromsoe, Vardoe and even from a plane near Alta. These Proceedings contain a selection of the lectures delivered on 2-3 June 2012, and also a narrative description of the transit viewing from Tromsoe, Vardoe and Alta. The title of the book, Meeting Venus, refers the title of a play by the Hungarian film director, screenwriter and opera director Istvan Szabo (1938-). The autobiographical movie Meeting Venus (1991) directed by him is based on his experience directing Tannhauser at the Paris Opera in 1984. The movie brings the story of an imaginary international opera company that encounters a never ending series of difficulties and pitfalls that symbolise the challenges of any multicultural and international endeavour. As is evident from the many papers presented in this book, Meeting Venus not only contains the epic tales of the transits of the seventeenth, eighteenth and nineteenth centuries, it also covers the conference

    The field of astronomy has recently benefited from the availability of space telescopes. The Hubble Space Telescope (HST), for instance, despite its problems, provides a unique and valuable view of the universe. However, unlike HST, a telescope need not be in low Earth orbit to escape our thickening atmosphere: it is currently technologically feasible to put a telescope on the moon, and there are excellent reasons for doing this. Either in low Earth orbit or on the moon, a space telescope represents an expensive and sought-after resource. Thus, the planning, scheduling, and control of these telescopes is an important problem that must be seriously studied.

  4. Observations of Low-degree Modes from the Solar Maximum Mission (extended Abstract)

    NASA Technical Reports Server (NTRS)

    Woodard, M.

    1984-01-01

    Mean frequencies, amplitudes, and linewidths for the solar 5 min p mode oscillations of degree 0, 1, and 2 have been obtained from approx. 280 days of SMM-ACRIM total irradiance data. The frequencies are in good agreement with measurements obtained from velocity data. The amplitudes of the modes lie along a well defined envelope of power vs. frequency, which peaks at 3.1 mHz and has a width of 0.7 mHz (FWHM). The r.m.s. amplitude of the highest peak in the spectrum (n=21, l=1) is approx. 3 ppm of the total flux. The linewidths of the narrowest l=O modes are approx. 1 micro Hz (FWHM). A broad continuum of power caused both by solar surface granulation and by instrumental noise interferes with the analysis of 5 min modes. The continuum spectral power in a 1 micro Hz band near 3 mHz corresponds to an apparent r.m.s. variation of approx. 0.5 parts per million of the mean solar flux.

    2001-01-01

    Given the problem of mutation saturation in ancient molecular sequences, there is great interest in inferring phylogenies from higher-order types of molecular data that change more slowly, such as genomic organization and the secondary and tertiary structures of ribosomal RNA and proteins. In this paper, we define edit distances based on two representations of RNA secondary structure, arc annotation and hierarchical string annotation, and give algorithms for computing these distances on pairs of annotated sequences, aligning pairs of annotated sequences, and computing 3-median annotated sequences from triples of annotated sequences. The 3-median algorithms can be used as part of a well-known iterative heuristic for inferring phylogenies. All given algorithms are adapted from algorithms for computing longest common annotated subsequences of pairs of annotated sequences.

    The use of motion picture cameras and film in analyzing moving objects, particular] high speed motion, has played an important role in the access of information. Not only does film furnish a picture with high resolution, it is relatively inexpensive and easy to use. Various situations where film has been used successfu include missile firings, sled track runs, rocket lift-offs, automobile crash studie radiology studies, sports analysis, with emplasis on football, and various industri motion applications. More specifically, in research applications, the study of Met Attitude, Failure, and Position. This presentation is directed primarily to the history and development of analytica projectors used in viewing motion picture film with emphasis on high speed moving pictures in the 100 to 10,000 frames per second mode. Various types of film have been used. Cameras such as Fairchid, Fastax, PhotoSonics, Askania, Red Lake, Milliken, Bell Howell, Eastman Kodak, etc.

  10. An approach to verification and validation of a reliable multicasting protocol: Extended Abstract

    Callahan, John R.; Montgomery, Todd L.

    1995-01-01

    This paper describes the process of implementing a complex communications protocol that provides reliable delivery of data in multicast-capable, packet-switching telecommunication networks. The protocol, called the Reliable Multicasting Protocol (RMP), was developed incrementally using a combination of formal and informal techniques in an attempt to ensure the correctness of its implementation. Our development process involved three concurrent activities: (1) the initial construction and incremental enhancement of a formal state model of the protocol machine; (2) the initial coding and incremental enhancement of the implementation; and (3) model-based testing of iterative implementations of the protocol. These activities were carried out by two separate teams: a design team and a V&V team. The design team built the first version of RMP with limited functionality to handle only nominal requirements of data delivery. This initial version did not handle off-nominal cases such as network partitions or site failures. Meanwhile, the V&V team concurrently developed a formal model of the requirements using a variant of SCR-based state tables. Based on these requirements tables, the V&V team developed test cases to exercise the implementation. In a series of iterative steps, the design team added new functionality to the implementation while the V&V team kept the state model in fidelity with the implementation. This was done by generating test cases based on suspected errant or off-nominal behaviors predicted by the current model. If the execution of a test in the model and implementation agreed, then the test either found a potential problem or verified a required behavior. However, if the execution of a test was different in the model and implementation, then the differences helped identify inconsistencies between the model and implementation. In either case, the dialogue between both teams drove the co-evolution of the model and implementation. We have found that this interactive, iterative approach to development allows software designers to focus on delivery of nominal functionality while the V&V team can focus on analysis of off nominal cases. Testing serves as the vehicle for keeping the model and implementation in fidelity with each other. This paper describes (1) our experiences in developing our process model; and (2) three example problems found during the development of RMP. Although RMP has provided our research effort with a rich set of test cases, it also has practical applications within NASA. For example, RMP is being considered for use in the NASA EOSDIS project due to its significant performance benefits in applications that need to replicate large amounts of data to many network sites.

    We extract the surface structure of the unstable invariant manifold tube projected into position space, of a halo orbit near L2. We do this by using transversal planes to intersect trajectories that approximate the tube. From these intersection points we construct spline-interpolated cross section curves which give a good idea of the structure of the tube. For example, we show that, for the value of (mu) we use, the tube pinches, develops a self-intersection, develops loop-inside-tube structure, pinches some more, and so on. We also construct surfaces made of quadrilaterals and triangles from these cross-sections. The transversal planes are obtained by taking planes orthogonal to a curve that follows the general shape of the tube. One such curve we use, is the unstable invariant manifold of the equilibrium point L2 itself. In another example, we take a circle that follows the tube, as the curve for finding planes transversal to the tube. Our method is complementary to the method of taking cross-sections of constant time (the isochronous method), as used by some other researchers. The isochronous method is good at revealing the temporal structure of trajectories on a tube. However, due to the unequal speeds of different trajectories, it is harder to use for long length surface extraction. In contrast, using our method, we show cross-sections of the tube through an angular extent of nearly (pi) during which the tube becomes extremely convoluted. We also show that tubes of different energies, that start out in certain ordering, do not obey the ordering after a while. Our work is motivated by applications to space mission design.

  14. Low cost booster and high performance orbit injection propulsion extended abstract

    Sackheim, R. L.

    1994-01-01

    Space transportation is currently a major element of cost for communications satellite systems. For every dollar spent in manufacturing the satellite, somewhere between 1 and 3 dollars must be spent to launch the satellite into its initial operational orbit. This also makes the weight of the satellite a very critical cost factor because it is important to maximize the useful payload that is placed into orbit to maximize the return on the original investment. It seems apparent then, that tremendous economic advantage for satellite communications systems can be gained from improvements in two key highly leveraged propulsion areas. The first and most important economic improvement can be achieved by significantly lowering the cost of today's launch vehicles. The second gain that would greatly benefit the communications satellite business position is to increase both the useful (payload) weight placed into the orbit and the revenue generating lifetime of the satellite on-orbit. The point of this paper is to first explain that these two goals can best be achieved by cost reduction and performance increasing advancements in rocket propulsion for both the launch vehicle and for the satellite on-board apogee insertion and on-orbit velocity control systems.

  17. A Unified Representation Scheme for Solid Geometric Objects Using B-splines (extended Abstract)

    Bahler, D.

    1985-01-01

    A geometric representation scheme called the B-spline cylinder, which consists of interpolation between pairs of uniform periodic cubic B-spline curves is discussed. This approach carries a number of interesting implications. For one, a single relatively simple database schema can be used to represent a reasonably large class of objects, since the spline representation is flexible enough to allow a large domain of representable objects at very little cost in data complexity. The model is thus very storage-efficient. A second feature of such a system is that it reduces to one the number of routines which the system must support to perform a given operation on objects. Third, the scheme enables easy conversion to and from other representations. The formal definition of the cylinder entity is given. In the geometric properties of the entity are explored and several operations on such objects are defined. Some general purpose criteria for evaluating any geometric representation scheme are introduced and the B-spline cylinder scheme according to these criteria is evaluated.

    1992-01-01

    The work described in this paper was inspired by a surprisingly effective neural network developed for scheduling astronomical observations on the Hubble Space Telescope. Our heuristic constraint satisfaction problem (CSP) method was distilled from an analysis of the network. In the process of carrying out the analysis, we discovered that the effectiveness of the network has little to do with its connectionist implementation. Furthermore, the ideas employed in the network can be implemented very efficiently within a symbolic CSP framework. The symbolic implementation is extremely simple. It also has the advantage that several different search strategies can be employed, although we have found that hill-climbing methods are particularly well-suited for the applications that we have investigated. We begin the paper with a brief review of the neural network. Following this, we describe our symbolic method for heuristic repair.

    Dynamic group Diffie-Hellman protocols for Authenticated Key Exchange(AKE) are designed to work in scenario in which the group membership is not known in advance but where parties may join and may also leave the multicast group at any given time. While several schemes have been proposed to deal with this scenario no formal treatment for this cryptographic problem has ever been suggested. In this paper, we define a security model for this problem and use it to precisely define Authenticated Key Exchange (AKE) with ''implicit'' authentication as the fundamental goal, and the entity-authentication goal as well. We then define in this model the execution of a protocol modified from a dynamic group Diffie-Hellman scheme offered in the literature and prove its security.

    Factors related to the path of abstracts from presentation at a conference to publication as a full article have been analyzed in the medical field, but only a few studies have been performed in dentistry. This study investigated the rate of publication of articles based on abstracts presented at the American Dental Education Association (ADEA) Annual Session & Exhibition in 2002 and 2003 and the time lag to publication. This study also aimed to characterize the abstracts and subsequent articles and determine if there were any significant factors related to expansion of an abstract into a full manuscript. A total of 370 abstracts met the inclusion criteria and were examined for this study. Subsequent published articles were located using a standard PubMed search. Descriptive statistics and bivariate analyses were used to analyze the data collected (α=0.05). Results suggest that there was a low (19 percent) publication rate for articles based on abstracts presented at the meetings studied. The median time between abstract presentation and article publication was ten months. Factors that showed significant correlation to likelihood of article publication were multiple affiliations, presence of analytical statistics, and, to a lesser extent, funding. We suggest that presenters at these meetings should expand their abstracts into full manuscripts and seek to publish them in peer-reviewed journals for the benefit of the profession.

    One of the main challenges of embodied theories is accounting for meanings of abstract words. The most common explanation is that abstract words, like concrete ones, are grounded in perception and action systems. According to other explanations, abstract words, differently from concrete ones, would activate situations and introspection; alternatively, they would be represented through metaphoric mapping. However, evidence provided so far pertains to specific domains. To be able to account for abstract words in their variety we argue it is necessary to take into account not only the fact that language is grounded in the sensorimotor system, but also that language represents a linguistic-social experience. To study abstractness as a continuum we combined a concrete (C) verb with both a concrete and an abstract (A) noun; and an abstract verb with the same nouns previously used (grasp vs. describe a flower vs. a concept). To disambiguate between the semantic meaning and the grammatical class of the words, we focused on two syntactically different languages: German and Italian. Compatible combinations (CC, AA) were processed faster than mixed ones (CA, AC). This is in line with the idea that abstract and concrete words are processed preferentially in parallel systems - abstract in the language system and concrete more in the motor system, thus costs of processing within one system are the lowest. This parallel processing takes place most probably within different anatomically predefined routes. With mixed combinations, when the concrete word preceded the abstract one (CA), participants were faster, regardless of the grammatical class and the spoken language. This is probably due to the peculiar mode of acquisition of abstract words, as they are acquired more linguistically than perceptually. Results confirm embodied theories which assign a crucial role to both perception-action and linguistic experience for abstract words.

    2008-10-01

    This paper presents a new methodology for analyzing complex networks in which the network of interest is first abstracted to a much simpler (but equivalent) representation, the required analysis is performed using the abstraction, and analytic conclusions are then mapped back to the original network and interpreted there. We begin by identifying a broad and important class of complex networks which admit abstractions that are simultaneously dramatically simplifying and property preserving we call these aggressive abstractions -- and which can therefore be analyzed using the proposed approach. We then introduce and develop two forms of aggressive abstraction: 1.) finite state abstraction, in which dynamical networks with uncountable state spaces are modeled using finite state systems, and 2.) onedimensional abstraction, whereby high dimensional network dynamics are captured in a meaningful way using a single scalar variable. In each case, the property preserving nature of the abstraction process is rigorously established and efficient algorithms are presented for computing the abstraction. The considerable potential of the proposed approach to complex networks analysis is illustrated through case studies involving vulnerability analysis of technological networks and predictive analysis for social processes.

    2011-01-01

    The present study investigated the neural correlates of the processing of abstract (low imageability) verbs. An extensive body of literature has investigated concrete versus abstract nouns but little is known about how abstract verbs are processed. Spanish abstract verbs including emotion verbs (e.g., amar, "to love"; molestar, "to annoy") were compared to concrete verbs (e.g., llevar, "to carry"; arrastrar, "to drag"). Results indicated that abstract verbs elicited stronger activity in regions previously associated with semantic retrieval such as inferior frontal, anterior temporal, and posterior temporal regions, and that concrete and abstract activation networks (compared to that of pseudoverbs) were partially distinct, with concrete verbs eliciting more posterior activity in these regions. In contrast to previous studies investigating nouns, verbs strongly engage both left and right inferior frontal gyri, suggesting, as previously found, that right prefrontal cortex aids difficult semantic retrieval. Together with previous evidence demonstrating nonverbal conceptual roles for the active regions as well as experiential content for abstract word meanings, our results suggest that abstract verbs impose greater demands on semantic retrieval or property integration, and are less consistent with the view that abstract words recruit left-lateralized regions because they activate verbal codes or context, as claimed by proponents of the dual-code theory. Moreover, our results are consistent with distributed accounts of semantic memory because distributed networks may coexist with varying retrieval demands.

One of the GRC roles is to provide Independent Verification and Validation of the Stirling TDC s. At the request of LM, a part of this effort includes the Extended Operation of the TDC s in the dynamically balanced dual-opposed configuration. Performance data of Stirling Convertors over time is required to demonstrate that an SRG110 can meet long-duration mission requirements. A test plan and test system were developed to evaluate TDC s #13 and #14 steady-state performance for a minimum of 5000 hours. Hardware, software and TDC preparation processes were developed to support this test and insure safe, round-the-clock operation of the TDC s. This paper will discuss the design and development, and status of the Extended Operation Test.

  13. Extended-release oxybutynin.

    Extended-release oxybutynin (Ditropan XL) uses an osmotic system (OROS) to deliver a controlled amount of oxybutynin chloride into the gastrointestinal tract over a 24-hour period when taken once daily. Oxybutynin binds to M3 muscarinic receptors on the detrusor muscle of the bladder, preventing acetylcholinergic activation and relaxing the muscle. Mean peak plasma concentrations are lower with extended-release oxybutynin 15mg once daily than with conventional immediate-release oxybutynin 5mg taken 3 times daily. Relative bioavailabilities of parent drug and metabolite N-desethoxybutynin are 153 and 69%, respectively, for extended-release oxybutynin when compared with immediate-release oxybutynin. In short (< or =6 weeks) randomised, double-blind clinical trials of patients with detrusor instability, extended-release oxybutynin 5 to 30mg once daily significantly reduced the mean weekly number of urge incontinence episodes by 84 to 90%. Extended-release oxybutynin had similar efficacy to immediate-release oxybutynin. Adverse events reported by patients taking extended-release oxybutynin were dose-related anticholinergic effects, most frequently dry mouth, somnolence, constipation, blurred vision and dizziness. A large noncomparative study demonstrated that approximately two thirds of the patients prescribed extended-release oxybutynin for detrusor instability were still taking the medication 6 months later.

    General purpose languages, such as C++, permit the construction of various high level abstractions to hide redundant, low level details and accelerate programming productivity. Example abstractions include functions, data structures, classes, templates and so on. However, the use of abstractions significantly impedes static code analyses and optimizations, including parallelization, applied to the abstractions complex implementations. As a result, there is a common perception that performance is inversely proportional to the level of abstraction. On the other hand, programming large scale, possibly heterogeneous high-performance computing systems is notoriously difficult and programmers are less likely to abandon the help from high level abstractions when solving real-world, complex problems. Therefore, the need for programming models balancing both programming productivity and execution performance has reached a new level of criticality. We are exploring a novel abstraction-friendly programming model in order to support high productivity and high performance computing. We believe that standard or domain-specific semantics associated with high level abstractions can be exploited to aid compiler analyses and optimizations, thus helping achieving high performance without losing high productivity. We encode representative abstractions and their useful semantics into an abstraction specification file. In the meantime, an accessible, source-to-source compiler infrastructure (the ROSE compiler) is used to facilitate recognizing high level abstractions and utilizing their semantics for more optimization opportunities. Our initial work has shown that recognizing abstractions and knowing their semantics within a compiler can dramatically extend the applicability of existing optimizations, including automatic parallelization. Moreover, a new set of optimizations have become possible within an abstraction-friendly and semantics-aware programming model. In the future, we will

    Current research is demonstrating that model-checking and other forms of automated finite-state verification can be effective for checking properties of software systems. Due to the exponential costs associated with model-checking, multiple forms of abstraction are often necessary to obtain system models that are tractable for automated checking. The Bandera Tool Set provides multiple forms of automated support for compiling concurrent Java software systems to models that can be supplied to several different model-checking tools. In this paper, we describe the foundations of Bandera's data abstraction mechanism which is used to reduce the cardinality (and the program's state-space) of data domains in software to be model-checked. From a technical standpoint, the form of data abstraction used in Bandera is simple, and it is based on classical presentations of abstract interpretation. We describe the mechanisms that Bandera provides for declaring abstractions, for attaching abstractions to programs, and for generating abstracted programs and properties. The contributions of this work are the design and implementation of various forms of tool support required for effective application of data abstraction to software components written in a programming language like Java which has a rich set of linguistic features.

    An investigation was undertaken into the possibility of automatically detecting how concepts exist in relation to each other in abstracts, a text-type commonly used in free-text retrieval. The end goal of this research is to capture these relationships in structured representations of abstracts' contents so that users can require not only that the…
