  1. Analysis of the Putative Remains of a European Patron Saint–St. Birgitta

    PubMed Central

    Saint Birgitta (Saint Bridget of Sweden) lived between 1303 and 1373 and was designated one of Europe's six patron saints by the Pope in 1999. According to legend, the skulls of St. Birgitta and her daughter Katarina are maintained in a relic shrine in Vadstena abbey, mid Sweden. The origin of the two skulls was assessed first by analysis of mitochondrial DNA (mtDNA) to confirm a maternal relationship. The results of this analysis displayed several differences between the two individuals, thus supporting an interpretation of the two skulls not being individuals that are maternally related. Because the efficiency of PCR amplification and quantity of DNA suggested a different amount of degradation and possibly a very different age for each of the skulls, an orthogonal procedure, radiocarbon dating, was performed. The radiocarbon dating results suggest an age difference of at least 200 years and neither of the dating results coincides with the period St. Birgitta or her daughter Katarina lived. The relic, thought to originate from St. Birgitta, has an age corresponding to the 13th century (1215–1270 cal AD, 2σ confidence), which is older than expected. Thus, the two different analyses are consistent in questioning the authenticity of either of the human skulls maintained in the Vadstena relic shrine being that of St. Birgitta. Of course there are limitations when interpreting the data of any ancient biological materials and these must be considered for a final decision on the authenticity of the remains. PMID:20169108

  3. Profit (p)-Index: The Degree to Which Authors Profit from Co-Authors

    PubMed Central

    Aziz, Nasir Ahmad; Rozing, Maarten Pieter

    2013-01-01

    Current metrics for estimating a scientist’s academic performance treat the author’s publications as if these were solely attributable to the author. However, this approach ignores the substantive contributions of co-authors, leading to misjudgments about the individual’s own scientific merits and consequently to misallocation of funding resources and academic positions. This problem is becoming the more urgent in the biomedical field where the number of collaborations is growing rapidly, making it increasingly harder to support the best scientists. Therefore, here we introduce a simple harmonic weighing algorithm for correcting citations and citation-based metrics such as the h-index for co-authorships. This weighing algorithm can account for both the nvumber of co-authors and the sequence of authors on a paper. We then derive a measure called the ‘profit (p)-index’, which estimates the contribution of co-authors to the work of a given author. By using samples of researchers from a renowned Dutch University hospital, Spinoza Prize laureates (the most prestigious Dutch science award), and Nobel Prize laureates in Physiology or Medicine, we show that the contribution of co-authors to the work of a particular author is generally substantial (i.e., about 80%) and that researchers’ relative rankings change materially when adjusted for the contributions of co-authors. Interestingly, although the top University hospital researchers had the highest h-indices, this appeared to be due to their significantly higher p-indices. Importantly, the ranking completely reversed when using the profit adjusted h-indices, with the Nobel laureates having the highest, the Spinoza Prize laureates having an intermediate, and the top University hospital researchers having the lowest profit adjusted h-indices, respectively, suggesting that exceptional researchers are characterized by a relatively high degree of scientific independency/originality.

  4. A generalized view of self-citation: direct, co-author, collaborative, and coercive induced self-citation.

    PubMed

    Ioannidis, John P A

    2015-01-01

    The phenomenon of self-citation can present in many different forms, including direct, co-author, collaborative, and coercive induced self-citation. It can also pertain to the citation of single scientists, groups of scientists, journals, and institutions. This article presents some case studies of extreme self-citation practices. It also discusses the implications of different types of self-citation. Self-citation is not necessarily inappropriate by default. In fact, usually it is fully appropriate but often it is even necessary. Conversely, inappropriate self-citation practices may be highly misleading and may distort the scientific literature. Coercive induced self-citation is the most difficult to discover. Coercive Induced self-citation may happen directly from reviewers of articles, but also indirectly from reviewers of grants, scientific advisors who steer a research agenda, and leaders of funding agencies who may espouse spending disproportionately large funds in research domains that perpetuate their own self-legacy. Inappropriate self-citation can be only a surrogate marker of what might be much greater distortions of the scientific corpus towards conformity to specific opinions and biases. Inappropriate self-citations eventually affect also impact metrics. Different impact metrics vary in the extent to which they can be gamed through self-citation practices. Citation indices that are more gaming-proof are available and should be more widely used. We need more empirical studies to dissect the impact of different types of inappropriate self-citation and to examine the effectiveness of interventions to limit them. PMID:25466321

  5. Coherent measures of the impact of co-authors in peer review journals and in proceedings publications

    NASA Astrophysics Data System (ADS)

    Ausloos, Marcel

    2015-11-01

    This paper focuses on the coauthor effect in different types of publications, usually not equally respected in measuring research impact. A priori unexpected relationships are found between the total coauthor core value, ma, of a leading investigator (LI), and the related values for their publications in either peer review journals (j) or in proceedings (p). A surprisingly linear relationship is found: ma(j) + 0.4 ma(p) = ma(jp) . Furthermore, another relationship is found concerning the measure of the total number of citations, Aa, i.e. the surface of the citation size-rank histogram up to ma. Another linear relationship exists : Aa(j) + 1.36 Aa(p) = Aa(jp) . These empirical findings coefficients (0.4 and 1.36) are supported by considerations based on an empirical power law found between the number of joint publications of an author and the rank of a coauthor. Moreover, a simple power law relationship is found between ma and the number (rM) of coauthors of an LI: ma ≃ rMμ ; the power law exponent μ depends on the type (j or p) of publications. These simple relations, at this time limited to publications in physics, imply that coauthors are a "more positive measure" of a principal investigator role, in both types of scientific outputs, than the Hirsch index could indicate. Therefore, to scorn upon co-authors in publications, in particular in proceedings, is incorrect. On the contrary, the findings suggest an immediate test of coherence of scientific authorship in scientific policy processes.

  10. Multiple narratives: How underserved urban girls engage in co-authoring life stories and scientific stories

    NASA Astrophysics Data System (ADS)

    Thompson, Jessica Jane

    Contemporary critics of science education have noted that girls often fail to engage in learning because they cannot "see themselves" in science. Yet theory on identity, engagement, and the appropriation of scientific discourse remains underdeveloped. Using identity as a lens, I constructed 2-two week lunchtime science sessions for 17 ethnic-minority high school girls who were failing their science classes. The units of instruction were informed by a pilot study and based on principles from literature on engagement in identity work and engagement in productive disciplinary discourse. Primary data sources included 19 hours of videotaped lunchtime sessions, 88 hours of audio-taped individual student interviews (over the course of 3--4 years), and 10 hours of audio-taped small group interviews. Secondary data sources included student journals, 48 hours of observations of science classes, teacher surveys about student participation, and academic school records. I used a case-study approach with narrative and discourse analysis. Not only were the girls individually involved in negotiating ideas about their narratives about themselves and their future selves, but collectively some of the girls productively negotiated multiple identities, appropriated scientific and epistemological discourse and learned science content. This was accomplished through the use of a hybrid discourse that blended identity talk with science talk. The use of this talk supported these girls in taking ownership for or becoming advocates for certain scientific ideas.

    Weglein, Arthur B.; Stolt, Bob H.

    2012-03-01

    Extracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.

  14. A Small World of Citations? The Influence of Collaboration Networks on Citation Practices

    PubMed Central

    Wallace, Matthew L.; Larivière, Vincent; Gingras, Yves

    2012-01-01

    This paper examines the proximity of authors to those they cite using degrees of separation in a co-author network, essentially using collaboration networks to expand on the notion of self-citations. While the proportion of direct self-citations (including co-authors of both citing and cited papers) is relatively constant in time and across specialties in the natural sciences (10% of references) and the social sciences (20%), the same cannot be said for citations to authors who are members of the co-author network. Differences between fields and trends over time lie not only in the degree of co-authorship which defines the large-scale topology of the collaboration network, but also in the referencing practices within a given discipline, computed by defining a propensity to cite at a given distance within the collaboration network. Overall, there is little tendency to cite those nearby in the collaboration network, excluding direct self-citations. These results are interpreted in terms of small-scale structure, field-specific citation practices, and the value of local co-author networks for the production of knowledge and for the accumulation of symbolic capital. Given the various levels of integration between co-authors, our findings shed light on the question of the availability of ‘arm's length’ expert reviewers of grant applications and manuscripts.

  17. Contributorships Are Not 'Weighable' to be Equal.

    PubMed

    Moustafa, Khaled

    2016-05-01

    A new trend to assign some authors as 'first co-authors' is noticeable in scientific publications as a statement highlighting that two or more authors 'contributed equally' to a reported work. However, the requirements of scientific rigor, honesty, and accuracy in academic standards make such statements invalid and, thus, should be avoided. A potential solution is to specify the role of each co-author, from study conception to communication of results, and let readers judge the importance of each contribution by themselves. Alternatively, authors should demonstrate how they contributed 'equally' when they are defined as 'equal contributors'. PMID:27025412

  2. Perceptions of Scholars in the Field of Economics on Co-Authorship Associations: Evidence from an International Survey.

    2016-01-01

    Scholars (n = 580) from 69 countries who had contributed articles in the field of Economics during the year 2015 participated in a survey that gauged their perceptions of various aspects of co-authorship, including its benefits, motivations, working relationships, order of authorship and association preferences. Among the main findings, significant differences emerged in the proportion of co-authored papers based on age, gender and number of years the researchers had spent in their present institution. Female scholars had a greater proportion of co-authored papers than male scholars. Respondents considered improved quality of paper, contribution of mutual expertise, and division of labor as the biggest benefits of and motivation for co-authorship. Contrary to common perceptions that Economics researchers used a predominantly alphabetical order of authorship, our study found that a considerable percentage of respondents (34.5%) had practiced an order of authorship based on the significance of the authors' contribution to the work. The relative importance of tasks differed significantly according to whether researchers co-authored as mentors or co-authored as colleagues. Lastly, researchers were found to associate, to varying degrees, with other researchers based on socio-academic parameters, such as nationality, ethnicity, gender, professional position and friendship. The study indicates that Economics authors perceive co-authorship as a rewarding endeavor. Nonetheless, the level of contribution and even the choice of association itself as a co-author depends to a great extent on the type of working relationship and socio-academic factors.

    1993-01-01

    The multi-ion, multi-event study of ion cyclotron resonance heating was funded to study ion energization through ion cyclotron resonance with low frequency broadband electromagnetic turbulence. The initial work on the ion cyclotron resonance heating (ICRH) of oxygen ions was presented in Crew et al. Crew and his co-authors developed a two-parameter representation of selected oxygen conic distributions and modeled the conic formation in terms of resonance heating. The first year seeks to extend the work of Crew and his co-authors by testing the applicability of the ICRH mechanism to helium ion conic distributions, using data obtained from the Energetic Ion Composition Spectrometer and the Plasma Wave Instrument on Dynamics Explorer 1.

  7. Unpacking teacher-researcher collaboration with three theoretical frameworks: a case of expansive learning activity?

    NASA Astrophysics Data System (ADS)

    Gade, Sharada

    2015-09-01

    Long association with a mathematics teacher at a Grade 4-6 school in Sweden, is basis for reporting a case of teacher-researcher collaboration. Three theoretical frameworks used to study its development over time are relational knowing, relational agency and cogenerative dialogue. While relational knowing uses narrative perspectives to explore the experiential and relational nature of collaboration; relational agency, draws on activity theory perspectives and identifies the change in the purpose of collaboration, from initially conducting classroom interventions to co-authoring research. Finally, cogenerative dialogue, deploys hermeneutic-phenomenological perspectives and investigates the dialogue that transpired between Lotta and the author, as they co-authored their research report. Such analysis sheds invaluable light on a case of expansive learning activity.

    A comprehensive scientificometric study was carried out on the publications of Corresponding member Prof Dr. K. Cilov, covering 127 monographs, textbooks and papers, published within the period 1929-1957. The results obtained were mathematically--statistically processed according to the methods of statistical grouping and alternative analysis and illustrated via table method and graphic analysis. The criteria of observation concern the quantitative, type and thematic characteristic of the co-authors of Prof K. Cilov. The analysis established an evenness in the scientific and publication creative work of Prof K. Cilov during the periods of his scientific maturing, his scientific interests directed mainly to the clinical-laboratory and cardiological problems, infectious and endocrine diseases. The percentage of his publications, with he as a sole author is 69,29%, and of team publications--30,71%. The personified co-authors are 32, and non-personified ones--65, with a predomination of the inconstant collaborators, so 70,87% of the co-authors are with a duration of the collaboration to 1 year.

    Collaboration plays an increasingly important role in research productivity and impact. However, it remains unclear whether female and male researchers in science, technology, engineering and mathematical (STEM) disciplines differ significantly from each other in their collaboration propensity. Here, we report on an empirical analysis of the complete publication records of 3,920 faculty members in six STEM disciplines at selected top U.S. research universities. We find that while female faculty have significantly fewer co-authors over their careers, this can be fully explained by their lower number of publications. Indeed, we also find that females tend to distribute their co-authoring opportunities among their co-authors more evenly than males do. Our results suggest that females have had a greater propensity to collaborate, in order to succeed in a historically men-dominated academic world. Surprisingly, we find evidence that in molecular biology there has been a gender segregation within sub-disciplines. Female faculty in molecular biology departments tend to collaborate with smaller teams and publish in journals and fields where typical team size is smaller. Our results identify gender-specific collaborative behaviors as well as disciplines with distinct patterns.

    2014-11-01

    An extraordinary focusing property of a parabolic mirror for ultracold neutrons in the presence of the gravitational field was first reported by Steyerl and co-authors. It was shown that all neutrons emitted from the focus of the mirror will be reflected back upon the same focus passing a point of return in the gravitational field in between. The present note offers a complementary geometric proof of this feature and discusses its application to many-mirror systems. The results can also be applied to electrons and ions in an electric field.

    With coordination from the APS Renewal Steering Committee (the members of which are the co-authors of this paper), staff and users of the U.S. Department of Energy's Advanced Photon Source (APS) at Argonne National Laboratory are in the process of developing a renewal plan for the facility. The renewal is a coordinated upgrade of the accelerator, beamlines, and associated technical structure that will enable users of the APS to address key scientific challenges in the coming decades. The cost of the renewal is estimated to be from $300M to $400M and to take approximately six years from start to finish.

  15. Looking for Daisy: constructing teacher identities

    NASA Astrophysics Data System (ADS)

    Ritchie, Stephen M.

    2009-09-01

    Research on teacher identities is both important and increasing. In this forum contribution I re-interpret assertions about an African American science teacher's identities in terms of Jonathon Turner's (2002) constructs of role identity and sub-identity. I contest the notion of renegotiation of identities, suggesting that particular role identities can be brought to the foreground and then backgrounded depending on the situation and the need to confirm a sub-identity. Finally, I recommend the inclusion of teachers' voices in identity research through greater use of co-authoring roles for teachers.

  19. A citation-based, author- and age-normalized, logarithmic index for evaluation of individual researchers independently of publication counts

    PubMed Central

    Belikov, Aleksey V.; Belikov, Vitaly V.

    2015-01-01

    The use of citation metrics for evaluation of individual researchers has dramatically increased over the last decade. However, currently existing indices either are based on misleading premises or are cumbersome to implement. This leads to poor assessment of researchers and creates dangerous trends in science, such as overproduction of low quality articles. Here we propose an index (namely, the L-index) that does not depend on the number of publications, accounts for different co-author contributions and age of publications, and scales from 0.0 to 9.9. Moreover, it can be calculated with the help of freely available software. PMID:26664709

    Following the acquittal of Dr Leonard Arthur in the case of the Down's syndrome infant the co-authors of the first paper in this symposium prepared a draft bill on the treatment of chronically disabled infants which has since been informally commended by the Director of Public Prosecutions. A second contributor, a law student, also argues for legislation as being the most effective way for society to have its standards clarified and observed. In a final paper Dr Havard, Secretary of the British Medical Association, opposes legislation believing it would raise far more problems than it would resolve. The first article was originally published in the Law Society's Gazette. PMID:6220153

    The detection of bioluminescense is widely used on the ground, while the detection of bioluminescence in space is still at the stage of detecting bright bioluminescense. With the rapid development of research in Space Life Sciences, it will be necessary to develop a detection technology to detect weak bioluminescense. Compared to other low-light detection techniques for ground, there are more advantages of EMCCDs for space application. Build a space bioluminescence imaging detection system, analysis the feasibility and capability of its will be significant. Co-Author:Xie Zongbao,Zheng Weibo

    2016-03-01

    This paper introduces the reader to a special issue of articles that explores links and processes behind societal change, climate change and environmental change in a Holocene perspective in the Mediterranean region. All papers are, by purpose, co-authored by scientists representing different disciplines. The cross-cutting theme has been to reach beyond simple explanations of potential climate-society relationships and advance our understanding on how to improve research methods and theories in the field. The thirteen papers in this issue address these questions in three different ways, by i) conceptual/methodological approaches; ii) review papers; and iii) case studies.

    On 25 March 1935 John Tate, the then editor of Physical Review, received a paper that Einstein had co-authored with Boris Podolsky and Nathan Rosen, his younger colleagues at Princeton. The logbooks of Physical Review show that the EPR paper, as it has since become known, bypassed the refereeing process and went straight to press. Four printed pages of beautifully constructed argument appeared in the 15 May issue. They were heralded by a brief article in the New York Times titled "Einstein attacks quantum theory". And so he did.

    2009-07-01

    Purpose: To develop a Radiation Therapy Oncology Group (RTOG) atlas of the elective clinical target volume (CTV) definitions to be used for planning pelvic intensity-modulated radiotherapy (IMRT) for anal and rectal cancers. Methods and Materials: The Gastrointestinal Committee of the RTOG established a task group (the nine physician co-authors) to develop this atlas. They responded to a questionnaire concerning three elective CTVs (CTVA: internal iliac, presacral, and perirectal nodal regions for both anal and rectal case planning; CTVB: external iliac nodal region for anal case planning and for selected rectal cases; CTVC: inguinal nodal region for anal case planning and for select rectal cases), and to outline these areas on individual computed tomographic images. The imaging files were shared via the Advanced Technology Consortium. A program developed by one of the co-authors (I.E.N.) used binomial maximum-likelihood estimates to generate a 95% group consensus contour. The computer-estimated consensus contours were then reviewed by the group and modified to provide a final contouring consensus atlas. Results: The panel achieved consensus CTV definitions to be used as guidelines for the adjuvant therapy of rectal cancer and definitive therapy for anal cancer. The most important difference from similar atlases for gynecologic or genitourinary cancer is mesorectal coverage. Detailed target volume contouring guidelines and images are discussed. Conclusion: This report serves as a template for the definition of the elective CTVs to be used in IMRT planning for anal and rectal cancers, as part of prospective RTOG trials.

  20. Are alexithymia and schizoid personality disorder synonymous diagnoses?

    Coolidge, Frederick L; Estey, Alisa J; Segal, Daniel L; Marle, Peter D

    2013-02-01

    Relationships among alexithymia, personality disorders, and higher-order psychopathological and interpersonal dimensions were examined in 199 college students and a close relative of each. Alexithymia, the difficulty to express and identify emotions, was measured by the Observer Alexithymia Scale (OAS; [Haviland, M. G., Warren, W. L., & Riggs, M. L. (2000). An observer scale to measure alexithymia. Psychosomatics, 41, 385-392]), which was completed by each student's relative. Each student completed three self-report measures: the Coolidge Axis II Inventory (CATI; [Coolidge, F. L. (2000). Coolidge Axis II Inventory: Manual. Colorado Springs, CO: Author.), the Five Dimensional Personality Test (5DPT; [van Kampen, D. (2009). Personality and psychopathology: A theory-based revision of Eysenck's PEN model. Clinical Practice and Epidemiology in Mental Health, 5, 9-21]), and the Horney-Coolidge Tridimensional Inventory (HCTI; [Coolidge, F. L. (1998). Horney-Coolidge Tridimensional Inventory: Manual. Colorado Springs, CO: Author]). Results indicated that higher levels of alexithymia are associated with personality disorders and their traits, such as schizoid, avoidant, and paranoid. With regard to the issue of the similarity and difference between alexithymia and schizoid personality disorder, there was sufficient evidence across all of the measures to suggest that they are not synonymous entities. Finally, alexithymic traits were associated with concurrent depressive traits even in a non-clinical sample. PMID:23021894

    Once defined primarily by their collections, by the end of the twentieth century, American natural history and science museums had become institutions defined largely by their displays. This talk will use life science and physics exhibits to illustrate how and why this transformation occurred. Efforts to modernize displays shaped and were themselves shaped by new institutional roles and identities for museums in twentieth-century science education and in American culture. Drawing on a forthcoming co-authored book (``Life on Display,'' U. Chicago, 2014) this talk will reveal the controversies that accompanied exhibition building, chronicling how and why curators, designers, and educators worked with and against one another to build displays intended to communicate new ideas about topics like evolution, animal behavior, and radiation to the American public. It explains that scientists were extraordinarily invested in the success of museums' displays and saw display as an integral element of their own public outreach work and research agendas. In turn, rapidly professionalizing exhibit designers were periodic participants in the research process, supplementing and sometimes prompting research projects through the displays they built. Presenting work that is co-authored by Rader and Victoria E.M. Cain (Northeastern University).

    This paper describes work done in the context of the Gaseous Electronics Conference (GEC) Plasma Data Exchange Project (PDEP) as discussed in the preface to this cluster issue. The purposes of this paper and its companion papers are to compare sets of cross sections for electron scattering from ground-state noble gas atoms in the energy range from thermal to about 1 keV and to comment on their applicability for plasma modelling. To these ends, we present in this paper intercomparisons of the nine independently derived sets of cross sections for electron scattering from ground-state argon atoms that have been posted in databases on the LXCat open-access website (www.lxcat.laplace.univ-tlse.fr). We show electron transport, excitation and ionization coefficients (swarm parameters) calculated using these cross section data in Boltzmann solvers and we compare calculated values with measurements. For the most part, the cross section sets have been compiled by co-authors on this paper and appendices giving details about how the various cross sections datasets were compiled have been written by the individual co-authors. Additional appendices discuss our criteria for selection of experimental data to be included in the comparisons and give a brief overview of the methods used here for solving the Boltzmann equation.

    Since the grant was renewed in 2000 and 2003 final technical reports of the grant have been previously submitted for those years. For that reason this final technical report covers the last four years of the grant. We had an exceptionally successful and productive last four years under the support of the grant. Our progress takes three different aspects, described in more detail below: 1.1 instrumentation, infrastructure, and other research support at Sector 20 of the Advanced Photon Source (APS); 1.2 research on which Profs. Stern or Seidler were PI?s; and 1.3 research on which Profs. Stern or Seidler were co-PI?s or where Drs. Dale Brewe or Julie Cross were authors or co-authors. Drs. Brewe and Cross are the two research scientists (permanently stationed at sector 20) who are supported by the grant. They provide support to the scientific goals of the grant and more broadly provide research support for many general users at Sector 20. Finally, in section 1.4 we provide a complete list of publications resulting from funding in the grant on which at least one of Stern, Seidler, Cross, or Brewe were co-authors. Given the inclusion of operations funding in the grant, this is of course a subset of the full scientific impact of the grant.

    Statistical analysis is error prone. A best practice for researchers using statistics would therefore be to share data among co-authors, allowing double-checking of executed tasks just as co-pilots do in aviation. To document the extent to which this ‘co-piloting’ currently occurs in psychology, we surveyed the authors of 697 articles published in six top psychology journals and asked them whether they had collaborated on four aspects of analyzing data and reporting results, and whether the described data had been shared between the authors. We acquired responses for 49.6% of the articles and found that co-piloting on statistical analysis and reporting results is quite uncommon among psychologists, while data sharing among co-authors seems reasonably but not completely standard. We then used an automated procedure to study the prevalence of statistical reporting errors in the articles in our sample and examined the relationship between reporting errors and co-piloting. Overall, 63% of the articles contained at least one p-value that was inconsistent with the reported test statistic and the accompanying degrees of freedom, and 20% of the articles contained at least one p-value that was inconsistent to such a degree that it may have affected decisions about statistical significance. Overall, the probability that a given p-value was inconsistent was over 10%. Co-piloting was not found to be associated with reporting errors. PMID:25493918

  5. An investigation of siderophore production by oceanic Synechococcus

    Cyanobacteria are significant contributors to global primary production. They can be found in warm high-nutrient, low-chlorophyll regions where low concentrations of iron are thought to limit primary productivity. Determining how these organisms obtain iron is critical to understanding the biogeochemical cycle of iron and its role as a determinant of marine primary production. Siderophore production has been observed in halotolerant freshwater cyanobacteria (see C.G. Trick and co-authors) and marine heterotrophic bacteria (see A. Butler, M.G. Haygood and co-authors), but to date, siderophore production in truly marine cyanobacteria has not been demonstrated. We examined the response of two marine Synechococcus species (WH7803 and WH8102) to iron stress. Axenic cultures of both Synechococcus species were grown under iron-stressed and iron-replete conditions. The supernatants of these cultures were examined using competitive ligand exchange-cathodic stripping voltammetry (CLE-CSV), a sensitive method of quantitative ligand detection. Observing ligand accumulation in culture is an analytical challenge due to the low cell densities and reduced growth rates of iron stressed marine cyanobacteria. Preliminary results suggest the presence of an iron-binding ligand in the iron-stressed cultures which was not present under iron-replete conditions. The amount of ligand produced by Synechococcus was approximately 1 × 10-18 mol/cell, comparable with the amount produced by marine heterotrophic bacteria (K. Barbeau, pers. comm.).

    The Intergovernmental Panel on Climate Change (IPCC) has completed its Fifth Assessment Report (AR5). Here, we explore the social scientific networks informing Working Group III (WGIII) assessment of mitigation for the AR5. Identifying authors’ institutional pathways, we highlight the persistence and extent of North-South inequalities in the authorship of the report, revealing the dominance of US and UK institutions as training sites for WGIII authors. Examining patterns of co-authorship between WGIII authors, we identify the unevenness in co-authoring relations, with a small number of authors co-writing regularly and indicative of an epistemic community’s influence over the IPCC’s definition of mitigation. These co-authoring networks follow regional patterns, with significant EU-BRICS collaboration and authors from the US relatively insular. From a disciplinary perspective, economists, engineers, physicists and natural scientists remain central to the process, with insignificant participation of scholars from the humanities. The shared training and career paths made apparent through our analysis suggest that the idea that broader geographic participation may lead to a wider range of viewpoints and cultural understandings of climate change mitigation may not be as sound as previously thought.

  7. Research Performance of Chinese Geoscientists and International Collaboration

    2011-12-01

    International collaboration has become increasingly important for Chinese geoscientists to excel in their careers. Here we present bibliometric evidence that top performing geoscientists in China tend to have international collaboration experiences. In this work we define top performers as those who have published most papers in American Geophysical Union (AGU)'s journals, and international collaboration as having co-authored papers with people whose major affiliations are not in China. We selected top performers as the 50 scientists who published most papers in AGU journals in all years excluding 2011. Among the top performers 96% of them have published with foreign co-authors in AGU journals. This is a clear indication that international collaboration can be very important to enhance performance. Another indication of the importance of international collaboration is that number of citations that each paper received by internationally collaborated papers is significantly higher than that by China-affiliation-alone papers. An example is that the top 10 papers that received most citations are all international collaboration papers.

    -body problem offers many challenging problems as does the open-shell many-body formalism. Substantial progress has been made in these fields in recent years and several good reviews and status reports were given. The physics of photoionization and photoabsorbtion is also a very active area of research and it was the subject of much stimulating discussions at the Symposium. The area of atoms in solids and at surfaces covers a wide range of interesting problems and some problems of particular atomic interest were selected. This volume contains practically all papers presented at the Symposium and therefore it should give an excellent picture of the actual Symposium program. Together the articles form an impressive report of recent developments of the field of atomic many-body theory in a broad sense, reviewing as well as pointing towards new problems and approaches. We ourselves experienced this symposium as an outstanding scientific event in the field, thanks to the excellent contributions of our participants. From the different expressions of appreciations we received after the Symposium we feel confident that our opinion was shared by many participants. We hope that these proceedings will convey to the reader something of the excitement felt by the participants during the Symposium week. We would like to place on record our thanks to all the participants who have contributed substantially in the planning of the Symposium by making valuable comments and suggestions and not the least to the members of our research groups for carrying out all the service functions during the Symposium and doing this so well. Mrs Agneta Connant deserves our very special thanks for her excellent work for the symposium on top of all her regular duties. Finally. we wish to express our gratitude to Mrs Birgitta Parenius and all the staff members at the Aspenäsgården for all their self-sacrificing efforts to make the Nobel Symposium such a memorable event.

  9. Fabrication of Si nanowires on Si (100) using a scanning probe tip

    2009-03-01

    Reliable fabrication on the nanoscale is becoming increasingly important. The co-author team is investigating a nanolithography technique for the deposition of nanoscale features entitled ``Tip-directed, field-emission assisted nanomanufacturing'' (TFAN). The TFAN process involves the adsorption of a layer of silicon-containing gas, such as disilane, to a substrate and the selective patterning of the surface with field-emitted electrons from a scanning probe tip. The electrons crack the Si containing molecules, which results in the deposition of Si on the substrate. The adsorption of the Si-containing molecules to the substrate surface is critical to the success of this approach. The investigation involves the determination of the coverage, sticking coefficient, and time constant of disilane on the Si(100) surface using temperature programmed desorption and scanning tunneling microscopy.

  10. Bridging the Gap Between Atomistics and Structural Engineering

    Langer, J. S.

    When Sid Yip asked me to write a commentary for this section of the handbook, I promptly reminded him that I am a co-author of a longer article in the section on mathematical methods. I told him that my article on amorphous plasticity, written with Michael Falk and Leonid Pechenik, already is more of a departure from conventional ideas than may be appropriate for a book like this one, which should serve as a reliable reference for years into the future; and I asked whether I really ought to be given yet more space for expressing my opinions. Sid insisted that I should write the commentary anyway. So here are some remarks about one of the topics of interest in this book, the search for predictive models of deformation and failure of solids, and the role of nonequilibrium physics in this effort.

    Today, quantum mechanical density functional theory is often the method of choice for performing accurate calculations on atomic, molecular and condensed matter systems. Here, I share some of my experiences in teaching the necessary basics of solid state physics, as well as the theory and practice of density functional theory, in a number of workshops held in developing countries over the past two decades. I discuss the advantages of supplementing the usual mathematically formal teaching methods, characteristic of graduate courses, with the use of visual imagery and analogies. I also describe a successful experiment we carried out, which resulted in a joint publication co-authored by 67 lecturers and students participating in a summer school.

    The specific objective of our project on CO{sub 2} ocean sequestration is to investigate its technical feasibility and to improve the understanding of any associated environmental impacts. Our ultimate goal is to minimize any impacts associated with the eventual use of ocean carbon sequestration to reduce greenhouse gas concentrations in the atmosphere. The project will continue through March 31, 2002, with a field experiment to take place in the summer of 2001 off the Kona Coast of Hawaii. At GHGT-4 in Interlaken, we presented a paper detailing our plans. The purpose of this paper is to present an update on our progress to date and our plans to complete the project. The co-authors of this paper are members of the project's Technical Committee, which has been formed to supervise the technical aspects and execution of this project.

    2013-01-01

    Bridging the gap between scholarship and teaching is perhaps the most difficult challenge facing faculty members in the sciences. Here I discuss a pedagogical strategy that combines these seemingly disconnected areas. In a semester-long, upper-level astronomical techniques class that has been offered three times at Macalester College, I have integrated a major research component into the curriculum. In each iteration of the course, students have analyzed new scientific data acquired with the National Radio Astronomy Observatory's Very Large Array (either from General Observer programs or from the "Observing for University Classes" program). Each of the three courses has produced a journal article in the peer-reviewed literature (Cannon et al. 2010, 2011, 2012); every student enrolled in these three courses is now a co-author on one of these manuscripts. Representative course design materials are presented here to motivate faculty members with diverse research specialties to undertake similar endeavors.

    We request time to observe 180 pulsars on a regular basis in order to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The main science goals are to increase the number of known gamma-ray pulsars (both radio loud and radio quiet), to determine accurate pulse profiles, and to characterise their high energy (phase-resolved) spectra. In the radio, the observations will also allow us to find glitches, characterise timing noise, investigate dispersion and rotation measure variability, and enhance our knowledge of single pulse phenomenology. To date, we are (co-)authors on 45 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of Lucas Guillemot and Damien Parent from the Bordeaux Fermi group and Kyle Watters from Stanford. Currently four students have active projects using the radio datasets.

    2016-01-01

    This paper discusses the 43+ year collaboration of Arthur Popper and Richard Fay. Over these years, we have co-authored over 30 papers and 55 books. The collaboration benefits from a strong friendship that includes our spouses and children. By any measure, our collaboration must be seen as being successful. The basis for this success is, we think, twofold. First, we have very complementary and overlapping research interests. This has enabled us to tackle issues, whether in research or in planning meetings or books, from different perspectives. Second, a hallmark of our successful collaboration has been our deep and close friendship and the extension of that friendship to our spouses and children. In this paper, we discuss some of the events that have shaped our collaboration, and some of the people who have impacted our lives. PMID:26515309

  18. Oscillatory Counter-Centrifugation: Effects of History and Lift Forces

    NASA Astrophysics Data System (ADS)

    Nadim, Ali

    2014-11-01

    This work is co-authored with my doctoral student Shujing Xu and is dedicated to the memory of my doctoral advisor Howard Brenner who enjoyed thought experiments related to rotating systems. Oscillatory Counter-Centrifugation refers to our theoretical discovery that within a liquid-filled container that rotates in an oscillatory manner about a fixed axis as a rigid body, a suspended particle can be made to migrate on average in the direction opposite to that of ordinary centrifugation. That is, a heavy (or light) particle can move toward (or away from) the rotation axis, when the frequency of oscillations is high enough. In this work we analyze the effects of the Basset history force and the Saffman lift force on particle trajectories and find that the counter-centrifugation phenomenon persists even when these forces are active.

  19. The sum of the parts: can we really reduce carbon emissions through individual behaviour change?

    PubMed

    Reynolds, Lucy

    2010-01-01

    Individuals are increasingly being urged to 'do their bit' in the fight against climate change, with governments and pro-environmentalists insisting that the collective impact of small behaviour changes will result in a meaningful reduction in global carbon emissions. The following paper considers this debate, as well as offering personal contributions from two leading environmentalists: Dr Doug McKenzie-Mohr, environmental psychologist and author of Fostering Sustainable Behavior: Community-Based Social Marketing; and Dr Tom Crompton, change strategist for WWF and co-author of Meeting Environmental Challenges: The Role of Human Identity, who argues for the role of intrinsic value systems in achieving sustainable behaviour change. As well as considering the responsibility of the individual in mitigating climate change, the paper introduces the discipline of social marketing as an effective tool for facilitating individual behaviour change, drawing on evidence from the field to recommend the key characteristics of effective behaviour change programmes.

    Frenkel', Viktor Ya

    1994-08-01

    One of his articles written with a co-author Gamov called 'My half-article'. Here his 'half-biography' is presented. It covers the first very important part of his life, starting from his youth in Odessa, his student years in Petrograd-Leningrad and several of his visits to Germany, Denmark, and England in connection with his scientific work. Special attention is devoted to his first scientific researches (1926-1928) at the Leningrad State University and to his relations with fellow students—M P Bronstein, D D Ivanenko, and L D Landau. His research into α-decay—its genesis and subsequent fate—is analysed. This article is in many respects based on new archive material.

  1. The Different Wavelengths of Radio Science

    Malecha, Jessica L.

    2005-01-01

    Radio Science covers many different avenues. This summer I attempted to work in each of the different avenues to learn the full range of subjects covered by Radio Science. I began my summer by traveling to Greece for the 3rd International Planetary Probe Workshop (IPPW-3). I went as a co-author of the Doppler Wind Experiment (DWE) team paper. My first job when I returned from Greece was to update the Radio Science activities webpage. I then used Fast Fourier Transforms (FFT) to find radio signals in recorded Radio Science experimental data and determine frequencies and powers. I read about and ran Fortran code being used to determine wind measurements on Huygens. I formatted and revised the abstracts and data lengths for the DVD data sets. By performing these tasks, I also learned the Unix operating system as well as a small amount of shell programming.

    Several papers have been given to national level meeting and a paper has been published in an international journal. Several additional papers have been co-author by students. The initial research project on the Atchafalaya Delta seems to have died in part due to a transfer of the NASA colleague to another location and subsequent reassigment to another job title. I have continued to include credit to NASA for many of my papers presented and published: A major debris flow along the Wasatch front in Northern Ogden; Spatial and volumetric changes in the Atchafalaya delta, Louisiana; An analysis of prehistoric Greenstone artifact in northern Alabama; An assessment of surfacing algorithm; Analysis of georeferencing algorithms to assess spatial accuracy.

  3. Seeing emotions: a review of micro and subtle emotion expression training

    NASA Astrophysics Data System (ADS)

    Poole, Ernest Andre

    2016-01-01

    In this review I explore and discuss the use of micro and subtle expression training in the social sciences. These trainings, offered commercially, are designed and endorsed by noted psychologist Paul Ekman, co-author of the Facial Action Coding System, a comprehensive system of measuring muscular movement in the face and its relationship to the expression of emotions. The trainings build upon that seminal work and present them in a way for either the layperson or researcher to easily add to their personal toolbox for a variety of purposes. Outlined are my experiences across the training products, how they could be used in social science research, a brief comparison to automated systems, and possible next steps.

  4. Mars water discoveries - implications for finding ancient and current life

    NASA Astrophysics Data System (ADS)

    Nelson, Mark

    2015-11-01

    There is some wonderful synchronicity right now for those interested in the search for water and life on Mars. Foremost is the recent announcement by NASA and the publication of a study using spectral imaging which definitively proves that there is seasonal, flowing briny water at a number of locations on Mars (see Fig. 1) (Ojha et al., 2015). This caps some 15 years of accumulating evidence that what was previously considered impossible is actually occurring on the Red Planet. "Water is essential to life as we know it," write Lujendra Ojha, Mary Beth Wilhelm, and their co-authors. "The presence of liquid water on Mars today has astrobiological, geologic, and hydrologic implications and may affect future human exploration".

  5. High speed transition prediction

    Gasperas, Gediminis

    1993-01-01

    The main objective of this work period was to develop, maintain and exercise state-of-the-art methods for transition prediction in supersonic flow fields. Basic state and stability codes, acquired during the last work period, were exercised and applied to calculate the properties of various flowfields. The development of a code for the prediction of transition location using a currently novel method (the PSE or Parabolized Stability Equation method), initiated during the last work period and continued during the present work period, was cancelled at mid-year for budgetary reasons. Other activities during this period included the presentation of a paper at the APS meeting in Tallahassee, Florida entitled 'Stability of Two-Dimensional Compressible Boundary Layers', as well as the initiation of a paper co-authored with H. Reed of the Arizona State University entitled 'Stability of Boundary Layers'.

  6. The analysis of PIP and BLZ latitude data and the free diurnal nutation

    NASA Astrophysics Data System (ADS)

    Damljanovic, Goran; et al.

    The values of the period (0.61 years from PIP and 0.58 years from BLZ data), the amplitude (0.012 arcseconds from PIP, 0.014 arcseconds from BLZ) and the phase (300 degrees from PIP, 320 degrees from BLZ; epoch: 1900.0) of the free diurnal nutation were computed using 13 years of Punta Indio (PIP data in the Hipparcos reference frame) and 37 years of the Belgrade (BLZ data in FK5 reference frame) homogenized latitude data. Both reductions are in line with MERIT Standards, with the standard IAU 1976 precession and IAU 1980 nutation. Direct Fourier transform analysis was applied to the data, and the results presented here (compared with each other and with the others) can be used to make some remarks concerning the IAU 1980 nutation model and polar motion.

    Are you familiar with the famed Generation Y, or "Gen Yers?" Generation Y is projected to be 47 percent of the workforce by 2014. They were born roughly between 1977 and 2000, but that is definitely not their only defining factor. But who is this group, and what do they have to do with the future of the space program and the Johnson Space Center (JSC)? During 2007, a group of Gen Yers at JSC participated on a committee to address the NASA Headquarters strategic communications plan. Fitzpatrick, along with his co-authors, created a presentation to share the Gen Yers' perspective on their generation in conjunction with the strategic communications strategy released. This knowledge capture (KC) event is that presentation.

    The students of the Glendale Community College's Astronomy Students for Telescope Research and Outreach (A.S.T.R.O.) Club have expanded their exoplanet transit observing program into observing asteroids. The students, most of whom are non-science majoring undergraduates, observed the asteroid 15 Eunomia using the 8-inch telescopes at the GCC North Observatory in Glendale, Arizona.Using concepts and skills learned in introductory astronomy courses for non-science majors, the co-authors measured the variability of the asteroid due to its rotation and constructed its lightcurve. Using the lightcurve inversion software from the Database of Asteroid Models from Inversion Techniques (DAMIT), a 3-dimensional model of the shape of 15 Eunomia was calculated. These results demonstrate that, given equipment that is readily available and affordable, asteroid observations have long-term educational potential for authentic, practical experience in both observational astronomy and numerical modeling, even with a small student body majoring in the physical sciences.

    Standardizing sampling methods for fish populations across large regions is important for consistent measurement of large-scale effects of climate or geography. In addition, pooling samples creates larger sample sizes and can facilitate data sharing among scientists and land managers. Sampling freshwater fish has largely not been standardized due to the diversity of fish and habitats. USGS aquatic ecologist Jason Dunham and co-authors contributed a chapter about sampling coldwater fish in wadeable streams to a new book that details common methods, protocols, and guidelines for sampling fish across North America. Topics include three common sampling methods: electrofishing, snorkeling, and nest counts. Each method provides complementary information about different species and life stages. The information will be useful for initiating new or fine-tuning ongoing sampling programs.

  13. Evidence-Based of Nonoperative Treatment in Adolescent Idiopathic Scoliosis

    PubMed Central

    2014-01-01

    Until now because there are many published journals with a variety of opinions so I will stratify these articles by giving weighted value on grade evaluation which depend on each institution (written author and co-authors) and external evaluate status (SCI, SCIE, impact factor) rather than the outcomes provided by each article. Consequently, before evaluating publicized papers, study quality assessment of each interesting paper should be performed by mean of gauging the quality of evidence. Reviewing these articles, a grade of medical literature was divided into the following 5 levels as level I (randomized controlled study), level II (non-randomized controlled study), level III (case-control study), level IV (case series), and level V (expert opinions). However, in present article I concluded only involved medical literatures with weighted value of level I and II evidence. PMID:25346826

    Here we provide the updated version of the guidelines of the European Association for Palliative Care (EAPC) on the use of opioids for the treatment of cancer pain. The update was undertaken by the European Palliative Care Research Collaborative. Previous EAPC guidelines were reviewed and compared with other currently available guidelines, and consensus recommendations were created by formal international expert panel. The content of the guidelines was defined according to several topics, each of which was assigned to collaborators who developed systematic literature reviews with a common methodology. The recommendations were developed by a writing committee that combined the evidence derived from the systematic reviews with the panellists' evaluations in a co-authored process, and were endorsed by the EAPC Board of Directors. The guidelines are presented as a list of 16 evidence-based recommendations developed according to the Grading of Recommendations Assessment, Development and Evaluation system. PMID:22300860

  16. The Initial Nine Space Settlements

    NASA Astrophysics Data System (ADS)

    Gale, Anita E.; Edwards, Richard P.

    2003-01-01

    The co-authors describe a chronology of space infrastructure development illustrating how each element of infrastructure enables development of subsequent more ambitious infrastructure. This is likened to the ``Southern California freeway phenomenon'', wherein a new freeway built in a remote area promotes establishment of gas stations, restaurants, hotels, housing, and eventually entire new communities. The chronology includes new launch vehicles, inter-orbit vehicles, multiple LEO space stations, lunar mining, on-orbit manufacturing, tourist destinations, and supporting technologies required to make it all happen. The space settlements encompassed by the chronology are in Earth orbit (L5 and L4), on the lunar surface, in Mars orbit, on the Martian surface, and in the asteroid belt. Each space settlement is justified with a business rationale for construction. This paper is based on materials developed for Space Settlement Design Competitions that enable high school students to experience the technical and management challenges of working on an industry proposal team.

    We request time to observe 170 pulsars on a regular basis in order to provide accurate ephemerides necessary for the detection of gamma-ray pulsars with the Fermi and AGILE satellites. The main science goals are to increase the number of known gamma-ray pulsars (both radio loud and radio quiet), to determine accurate pulse profiles, to characterise their high energy spectra and phase resolved spectroscopy of the brightest pulsars. In the radio, the observations will also allow us to find glitches, characterise timing noise, investigate dispersion and rotation measure variability and enhance our knowledge of single pulse phenomenology. To date, we are (co-)authors on 27 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of Lucas Guillemot and Damien Parent from the Bordeaux Fermi group (submitted mid 2009) and Kyle Watters from Stanford.

  8. The Electrophysiological MEMS Device with Micro Channel Array for Cellular Network Analysis

    NASA Astrophysics Data System (ADS)

    Tonomura, Wataru; Kurashima, Toshiaki; Takayama, Yuzo; Moriguchi, Hiroyuki; Jimbo, Yasuhiko; Konishi, Satoshi

    This paper describes a new type of MCA (Micro Channel Array) for simultaneous multipoint measurement of cellular network. Presented MCA employing the measurement principles of the patch-clamp technique is designed for advanced neural network analysis which has been studied by co-authors using 64ch MEA (Micro Electrode Arrays) system. First of all, sucking and clamping of cells through channels of developed MCA is expected to improve electrophysiological signal detections. Electrophysiological sensing electrodes integrated around individual channels of MCA by using MEMS (Micro Electro Mechanical System) technologies are electrically isolated for simultaneous multipoint measurement. In this study, we tested the developed MCA using the non-cultured rat's cerebral cortical slice and the hippocampal neurons. We could measure the spontaneous action potential of the slice simultaneously at multiple points and culture the neurons on developed MCA. Herein, we describe the experimental results together with the design and fabrication of the electrophysiological MEMS device with MCA for cellular network analysis.

  9. Dynamics of an impact oscillator with SMA constraint

    NASA Astrophysics Data System (ADS)

    Sitnikova, E.; Pavlovskaia, E.; Wiercigroch, M.

    2008-12-01

    The dynamic behaviour of an impact oscillator with an SMA constraint has been modelled and analysed. Following the formulation proposed by Bernardini and his co-authors [1,2] describing thermo-mechanics of SMA elements, we obtain a compact thermo-mechanical model of an impact pseudoelastic oscillator. Due to the mechanical characteristics of SMA element and non-smooth nature of the impacts, five different modes of operation can be distinguished for this system. The undertaken numerical investigation suggests that the system can exhibit complex dynamic responses which if appropriately controlled can be used for vibration reduction. For this reason alone a comparison with an equivalent elastic oscillator was made. It was found out that low amplitude regimes are not affected by the presence of SMA element. On contrary, for the large amplitude responses a significant vibration reduction was achieved due to the phase transformations.

These seven projects included the co-authoring of Voices From the Cape, historical work with NASA historian Roger Launius, the completion of a series of oral histories with key KSC personnel, a monograph on Public Affairs, the development of a Historical Concept Map (CMap) for history knowledge preservation, advice on KSC history database and web interface capabilities, the development of a KSC oral history program and guidelines of training and collection, and the development of collaborative relationships between Kennedy Space Center, the University of West Florida, and the University of Central Florida.

  11. [African silhouettes and field photography. M. Griaule's contribution to the Maussian "discovery" of body techniques].

    PubMed

    Despoix, Philippe

    2010-01-01

    This essay focuses on the interaction between the new reproduction media and corresponding reconfiguration of research fields in anthropology using the case of the "techniques of the body" - a concept developed by Marcel Mauss (1872-1950). For Mauss, the initiator of this discipline in France, body skills constituted the most important anthropological entity resulting from the confrontation of technical images and his interest in walking techniques. Three scenarios are especially significant for Mauss's formulation of "body techniques" as a genuine concept: the front during the World War I, a New Yorke hospital in 1926, and an ethnographical field study conducted in Africa during the ate 1920s. Both, the photographic media as well as the Abyssinian expedition of his student Marcel Griaule, whose research publication Mauss co-authored (Silhouettes et graffiti abyssins) n 1933, take centre stage here.

    This LTSA award funds my research on the origin of stellar X-ray emission and the solar-stellar analogy. The focus during most of this reporting period continued to be on the reduction and analysis of data acquired with the ASCA observatory (Advanced Satellite for Cosmology and Astrophysics). During the last few months of this reporting period, considerable time and effort was also devoted to the submission of AXAF observing proposals in preparation for the upcoming AXAF launch. During this reporting period, five papers appeared in refereed journals for which I was either author or co-author, and two additional papers have recently been submitted to ApJ. Also, three conference proceedings papers were submitted. These publications are listed in the attached bibliography.

  13. A Journal Paper Filtering Using the Multiple Information

    NASA Astrophysics Data System (ADS)

    Yamamoto, Masao; Kinukawa, Hiroshi

    A paper filtering system that supports the effective collection of related journal papers is becoming important as the technological progress has been rapid. However, previous systems realized insufficient filtering effectiveness, because of lack of available information in abstract part of journal papers that is available to the public. In this paper, we propose a paper filtering method using the multiple information such as structure, co-author, subject category, terminology, and terms in patent document. By the evaluation for 15 examinees using 4,875 journal papers, it became clear that for all examinees the effectiveness of proposed method exceeds the conventional method, when the all information above are used, which became closer to practical use.

    This article establishes the importance of "context", a concept that underpins the academic contributions that John Falk and Lynn Dierking have made in building the field of informal/free-choice learning in science education. I consider, in turn, the individual contributions made by each of them prior to their seminal co-authored work, entitled The Museum Experience. I then document their joint contributions to the field, pointing out that although their interests and skills overlap in complementary ways to produce their jointly authored works, both have continued to make their individual contributions; Falk in his work on identity and impact, and Dierking in her work on community, youth, family and equity. Finally I come to the present, describing how they each continue their research and publication in lifelong, life-wide, and life-deep learning, with a particular focus on free-choice learning and the role it can play in addressing critical issues in the world.

    2007-01-01

    The year 2006 marked 100 years since the death of Pierre Curie. It is therefore appropriate that we remember his life and his work, which was cut short by his untimely death from an accident on the Pont Neuf, Paris, on April 19, 1906. He had already accomplished much during his life, both before the discovery of radium with Marie Curie, in work co-authored with his brother Jacques on piezoelectricity, and afterwards, when he published the results of several experimental studies with radium and radon. He came from a medical family, and his grandfather Pierre Curie was a famous homeopathic physician. He has, in print, unfairly been relegated to the background—his own scientific contributions having been overtaken by the fame of Marie Curie, probably because she outlived him by 28 years.

  17. A new proposal for benefit-less-risk analysis in clinical trials.

    PubMed

    Chuang-Stein, C

    1994-02-01

    In this paper, we propose a method to discount the observed benefit of a treatment by the observed risk in order to facilitate the benefit-less-risk comparison of treatments in a clinical trial. The discounting, applied to each individual in a trial, utilizes a method proposed by Chuang-Stein and co-authors to consolidate the safety data collected in the trial. The collating of the safety information allows one to estimate quantitatively the risk experienced by each individual, and therefore enables the construction of a risk-adjusted benefit measure for the same individual. We discuss the rationale for the adjusting method and examine its impact on the inference. When the discounting process reflects an individual's choice, the results should be interpreted at the individual level. An example is given to illustrate the approach. PMID:7908619

    Objective This paper aims to present an overview of screening and safety considerations for the treatment of clinical depressive disorders and make recommendations for safety monitoring. Method Data were sourced by a literature search using MEDLINE and a manual search of scientific journals to identify relevant articles. Draft guidelines were prepared and serially revised in an iterative manner until all co-authors gave final approval of content. Results Screening and monitoring can detect medical causes of depression. Specific adverse effects associated with antidepressant treatments may be reduced or identified earlier by baseline screening and agent-specific monitoring after commencing treatment. Conclusion The adoption of safety monitoring guidelines when treating clinical depression is likely to improve overall physical health status and treatment outcome. It is important to implement these guidelines in the routine management of clinical depression. PMID:21888608

    Boulding, David M; Brooks, Susan L

    2010-01-01

    This article demonstrates the usefulness of an innovative framework called "Relationship-Centered Lawyering" to enhancing real world legal practice. It uses the example of lawyers, particularly criminal defense lawyers, who often deal with clients with cognitive challenges. The article developed out of a series of workshops conducted jointly by the co-authors, an American law professor with a social work background, and a Canadian criminal defense lawyer and family mediator who is an international expert on Fetal Alcohol Spectrum Disorder and other Neuro-Behavioral Disorders (FA/NB). The paper describes the relational theory Brooks developed (along with Robert Madden), along with the science of cognitive impairments, with a specific focus on FA/NB. The paper provides two illustrations of the relational framework by explaining Boulding's strategy of creating what is called the "external brain" and his techniques of relational interviewing.

    Dr. McCrone was an amazing individual, possessing many talents and having many interests. He especially loved applying polarized light microscopy (PLM) to answering the question-at-hand and solving problems. He applied PLM to many different fields including the identification of air pollution particles, asbestos identification, art conservation, pharmaceuticals, industry problems and forensic sciences. A field that I believe he enjoyed the most was the characterization and identification of explosives. Throughout his life he worked on, gave presentations and published articles on the characterization and identification of explosives. Also, he encouraged other scientists to give presentations and publish on the subject by providing "behind the scene" advice and/or be a co-author on a paper. He unselfishly taught others how to apply PLM and incorporate this invaluable tool into their analytical scheme. PMID:15027545

    Rao, Yuanqiao

    Inorganic nanoparticles have the potential of providing functionalities that are difficult to realize using organic materials; and nanocomposites is an effective mean to impart processibility and construct bulk materials with breakthrough properties. The dispersion and assembly of nanoparticles are critical to both processibility and properties of the resulting product. In this talk, we will discuss several methods to control the hierarchical structure of nanoparticles in polymers and resulting rheological, mechanical and optical properties. In one example, polymer-particle interaction and secondary microstructure were designed to provide a low viscosity composition comprising exfoliated high aspect ratio clay nanoparticles; in another example, the microstructure control through templates was shown to enable unique thermal mechanical and optical properties.

    Halar, E M

    1999-11-01

    Epidemiologic and prospective cohort studies have shown a strong correlation between risk factors and stroke morbidity and mortality. The reduction or control of risk factors, on the other hand, can reduce stroke morbidity and mortality. Rehabilitation professionals involved in comprehensive rehabilitation of stroke patients may include the management of risk factors in the scope of their practice and thus contribute to longer life expectancy and improved quality of life of these patients. Decreasing disability, improving quality of life, and prolonging life are chief goals of the rehabilitation process. This article reviews the rationale for risk management and stresses the value of aerobic and conditioning exercises and is intended to supplement the article on stroke prevention co-authored by Daryl Gress and Vineeta Singh.

    We have sought to broaden our department's research capacity using two different interdisciplinary approaches. First, we created the Evans Center for Interdisciplinary Biomedical Research (ECIBR) — a virtual center that promotes and funds Affinity Research Collaboratives (ARCs) initiated by faculty from within and outside Boston University (BU). Of the 11 funded ARCs, the 4 ARCs in existence for a minimum of 3 years have a total of 37 participants, 93 co-authored publications, and 33 new grants. Second, the Department of Medicine (DOM) created a Section of Computational Biomedicine in 2009 to enhance analytical and computational expertise in the DOM. After 3 years, the section is comprised of 10 faculty members and 21 trainees. The faculty members have collaborated with 20 faculty members in other sections or departments and secured 12 extramural grants (totaling ∼$20 million in direct costs). The ECIBR and the Section of Computational Biomedicine represent new organizational approaches to stimulating innovation in research in a DOM. PMID:23874035

  7. Microbial biodiversity of the atmosphere

    Klein, Ann Maureen

    Microorganisms are critical to the functioning of terrestrial and aquatic ecosystems and may also play a role in the functioning of the atmosphere. However, little is known about the diversity and function of microorganisms in the atmosphere. To investigate the forces driving the assembly of bacterial microbial communities in the atmosphere, I measured temporal variation in bacterial diversity and composition over diurnal and inter-day time scales. Results suggest that bacterial communities in the atmosphere markedly vary over diurnal time scales and are likely structured by inputs from both local terrestrial and long-distance sources. To assess the potential functions of bacteria and fungi in the atmosphere, I characterized total and potentially active communities using both RNA- and DNA-based data. Results suggest there are metabolically active microorganisms in the atmosphere that may affect atmospheric functions including precipitation development and carbon cycling. This dissertation includes previously published and unpublished co-authored material.

    Rare events are those that occur with a very low probability in experiment, or are common but difficult to sample using standard computer simulation techniques. Such processes require advanced methods in order to obtain useful results in reasonable amounts of computer time. We discuss some of those techniques here, including the ``barrier'' method, splitting methods, and a Forward-Flux Sampling in Time (FFST) algorithm, and apply them to measure the nucleation times of the first-order transition in the Ziff-Gulari-Barshad model of surface catalysis, including nucleation in finite equilibrium states, which are measured to occur with probabilities as low as 10°C(-40). We also study the transitions in the Maier-Stein model of chemical kinetics, and use the methods to find the harmonic measure in percolation and Diffusion-Limited Aggregation (DLA) clusters. co-authors: David Adams, Google, and Leonard Sander, University of Michigan.

    Human activities have greatly increased nitrogen emissions and deposition across large areas of Earth. Although nitrogen is an essential nutrient for plant growth, too much nitrogen in excess of critical loads leads to losses of biodiversity, soil and stream acidification, nutrient imbalances, and other deleterious effects. In a new report quantifying critical loads of nitrogen deposition across the United States, USGS scientist Steve Perakis and co-authors provided a chapter about responses of marine west coast forests. Much of this region is understudied with respect to nitrogen deposition, and in this chapter the authors identify known adverse effects and estimate critical loads of nitrogen deposition for western Oregon and Washington and southeast Alaska forests. Perakis also contributed to the synthesis chapter, which includes background, objectives, advantages and uncertainties of critical loads, an overview of critical loads across U.S. ecoregions, and other topics.

    1981-01-01

    A paleoecological analysis of the fossil record before and after the Cretaceous/Tertiary boundary indicates that the widespread extinctions and biological stresses around the boundary are best explained in terms of a sudden, significant, but short temperature rise. L. Alvarez and co-authors, having found an enrichment in iridium at the same boundary, postulated that it was associated with the impact of an extraterrestrial body. If this body struck the ocean, the water injected into the atmosphere may have led to a transient increase in the global surface temperature. This temperature pulse may have been primarily responsible for the effects observed in the biosphere. The pattern of extinction of higher plant species suggests that splash down occurred in the northern Pacific-Bering Sea area. ?? 1981.

    Interhelioprobe (IHP), an analogue to the ESA Solar Orbiter, is the prospective Russian space solar observatory intended for in-situ and remote sensing investigations of the Sun and the inner heliosphere from a heliocentric orbit with the perihelion of about 60 solar radii. One of several instruments on board will be the Bragg crystal spectrometer ChemiX which will measure X-ray spectra from solar corona structures. Analysis of the spectra will allow the determination of the elemental composition of plasma in hot coronal sources like flares and active regions. ChemiX is under development at the Wrocław Solar Physics Division of the Polish Academy of Sciences Space Research Centre in collaboration with an international team (see the co-author list). This paper gives an overview of the ChemiX scientific goals and design preparatory to phase B of the instrument development.

  13. Race, gender and the econophysics of income distribution in the USA

    Shaikh, Anwar; Papanikolaou, Nikolaos; Wiener, Noe

    2014-12-01

    The econophysics “two-class” theory of Yakovenko and his co-authors shows that the distribution of labor incomes is roughly exponential. This paper extends this result to US subgroups categorized by gender and race. It is well known that Males have higher average incomes than Females, and Whites have higher average incomes than African-Americans. It is also evident that social policies can affect these income gaps. Our surprising finding is that nonetheless intra-group distributions of pre-tax labor incomes are remarkably similar and remain close to exponential. This suggests that income inequality can be usefully addressed by taxation policies, and overall income inequality can be modified by also shifting the balance between labor and property incomes.

    2011-10-01

    EV Aquarii is a variable star which was formerly misclassified as a cataclysmic variable, but photometric observations and colour indices have since indicated that it is most likely a semiregular M giant. The authors of this paper have used self-correlation analysis and Fourier analysis to determine the variability profile of the star. Data from the AAVSO International Database, the All-Sky Automated Survey, The Amateur Sky Survey, and co-author Arne Henden were used. The period of variation has been found to be 123.6 days ± 2.1 days. The amplitude of this variation is not constant; it changes with time between approximately 0.4 and 1.0 magnitude. There were no indications of a longer secondary period, though there has been observed an instance of a transient period of variation on a shorter timescale of about 40 days. There was no evidence found of periodic variation of the color differences.

    The wind tunnel test results have been published in the literature as summarized at the end of this report. As part of the education program, an introduction to engineering course module was designed and tested on 80 freshman engineering students at Old Dominion University. The five-week module required that five-person teams design, build and fly a radio-controlled airplane using only the wind tunnel data developed by the Wright brothers in 1902. That module is described in Sparks and Ash (2001). The Principal Investigator has co-authored one dozen publications resulting from this research, as listed at the end of this report. The Principal Investigator has given fourteen lectures on the Wright brother testing program and has appeared in two documentary television programs (summarized at the end of this report). Speaking invitations have continued since the completion of the project.

This paper provides a critical overview of the relationship education field and sets an agenda for research and practice for the next decade. A theme weaved throughout the paper are the ways in which relationship education is similar and different from couples therapy and we conclude that there can be a synergistic, healthy marriage between the two. We then provide recommendations for future directions for research in the relationship education field. Finally, the co-authors comment on our experiences in both the relationship education field and couples therapy field as both researchers and interventionists. PMID:22283386

  19. Diagnosing a daily index of tornado variability with global reanalysis

    NASA Astrophysics Data System (ADS)

    Pegion, P. J.; Hoerling, M. P.

    2011-12-01

    The recent record setting tornado outbreaks in April 2011 has spurred a lot of discussion and debate of the causes of this record setting month. Global warming and the decaying La Niña were both common causes suggested as the reason behind such a destructive tornado season. Due to the inhomogeneity of the observed tornado record, there are few published studies that relate climate variability to occurrences of tornados. We employ a method developed by Harold Brooks and co-authors in 2003 that discriminates tornadic and severe weather soundings from everyday convection to circumvent the problems with the observed tornado record. We will show how this index, derived from the CFS-R, realistically reproduces the observed variability in tornadoes, and the relative impacts of different modes of climate variability on tornadoes over the United States. This analysis will provide a baseline that will be expanded to climate model simulations of the 20th Century and future projections.

  20. X-ray/UV variability and the origin of soft X-ray excess emission from II Zw 177

    NASA Astrophysics Data System (ADS)

    Pal, Main

    We study a detailed broad-band X-ray/UV emission from the narrow line Seyfert 1 galaxy II Zw 177 based on two XMM-Newton and single Swift/XRT observations. Both XMM-Newton observations show the soft X-ray excess emission below 2 keV when the best-fit 2 - 10 keV power law is extrapolated down to 0.3 keV. We find the blurred reflection from an ionized accretion disc and Comptonized disc emission both describe the observed soft excess well. We find a remarkable trend of decreasing UV flux with increasing soft X-ray excess and power law emission. We suggest that this could be due to that the external edge of corona hide a fraction of accretion disk. Co-Author: Prof. Gulab C.

    In interplanetary flight, after large solar flares, cosmonauts are subjected to the action of energetic solar protons and electrons. These energetic particles have an especially strong effect during extravehicular activity or (in the future) during residence on the surface of Mars, when they spend an extended time there. Such particles reach the orbits of the Earth and of Mars with a delay of several hours relative to solar X-rays and UV radiation. Therefore, there is always time to predict their appearance, in particular, by means of an X-ray-UV radiometer from the apparatus complex of the Space Solar Patrol (SSP) that is being developed by the co-authors of this paper. The paper discusses the far unexplored biophysical problem of manned flight to Mars, scheduled for the next decade. In long-term manned space flights on the orbital stations "Salyut" Soviet cosmonaut crews from three of the co-authors (cosmonauts V.V. Kovalenok, A.S. Ivanchenkov, and V.P. Savinykh) had repeatedly observed the effect of certain geophysical conditions on the psychological state of each crew. These effects coincide with the increased intensity of global illumination in the upper ionosphere space on flight altitudes (300-360 km). It is important that during all of these periods, most of the geomagnetic pulsations were completely absent. Possible ways to study the synergistic effects of the simultaneous absence of the geomagnetic field, the magnetic pulsations and the microwave radiation of the terrestrial ionosphere are considered for a flight to Mars.

    Scanning force microscopy (SFM) methods were developed to investigate the structure and the dynamics of E. coli transcription complexes. The described techniques will also be applicable to the study of other protein-nucleic acid complexes. First, the deposition process of DNA molecules onto a mica surface was investigated using polymer chain statistics. Conditions were found in which DNA molecules, and also protein-DNA complexes, are able to equilibrate on the surface. These findings imply that DNA and protein-DNA complexes attain a lowest energy state on the surface, and that meaningful structural information can, therefore, be obtained from the corresponding SFM images. Using these imaging conditions, SFM was then used to investigate various transcription complexes. The structures of crucial intermediates in the transcriptional activation of RNA polymeraseċsigma54 by NtrC were visualized and analyzed. Moreover, a new method was pioneered to identify the position of specific subunits in multi- protein assemblies. In this method, a specific subunit is tagged with a short piece of DNA which renders it easily recognizable in SFM images. This technique was employed to determine the positions of the two α subunits and the βsp/prime subunit in RNA polymerase-DNA complexes. Finally, SFM imaging in liquid was used to investigate the dynamics of the specific and non-specific interactions between RNA polymerase and DNA. Image sequences of an RNA polymerase actively transcribing a DNA template were obtained and analyzed. Image sequences of non-specific complexes were also obtained, and showed the RNA polymerase moving along the DNA in a one- dimensional random walk. The latter experiments provide some of the first direct evidence that RNA polymerase diffuses along DNA to facilitate promoter location. Chapters II, III, V and VI of this dissertation include material which has been previously published with co- authors. The co-authors are acknowledged at the beginning of

    Commercial mining towns on Earth become cities. Company towns need commerce to drive the growth and economy of early space colonies. Water is an early resource for camp consumables plus propellant export sales from asteroid mining operations at proposed burned out comets with water methane ice cores for sustainable growth over 50 years, financed from profits and capable with affordable logistics to support resource recovery. One co-author's perspective includes remote resource recovery sites on Earth. Other co-authors' experiences include architecture, lunar habitation, and architectural space colony concepts. This paper combines these experiences to propose commercial opportunities possible as mankind moves beyond one planet. Alaska's North Slope commercial history indicates that different multiple logistics transportation systems are required to reduce the risk to humans and families moved in before the oil flowed. Commercial enterprises have risked $20 billion and spent hundreds of billions in private money after profits were created. The lessons learned are applied to a burned out comet designated Wilson-Harrington (1979) and explores the architecture for early living within the burned out comet disk created from ice recovery and later sealed with an expected methane ice interior. Considered is the recovery of the resources, the transport of water back to Earth orbit or L-1, plus later the development of more comfortable space colony living. Commercial markets produce cities on Earth and the same can happen on Space Colonies. The key is an ``in place'' affordable commercial logistics system that can service, stimulate and sustain a 50-year commercial propellant market.

    There is a good deal of interest lately in whether or not rainfall varies with the day of the week in response to the weekly variations in human activity. The most likely cause of such changes in the U.S. would be from the weekly variations in pollution levels that are known to occur throughout the country. A paper on this topic will soon be published by the Journal of Geophysical Research entitled, "Midweek Increase in U.S. Summer Rain and Storm Heights Suggests Air Pollution Invigorates Rainstorms, by T. L. Bell, D. Rosenfeld, K.-M. Kim, J.-M. Yoo, M.-I. Lee, and M. Hahnenberger (referred to here as "Bell et al."). A paper by D. M. Schultz and co-authors was recently published in Geophysical Research Letters that claimed to contradict some of the results in Bell et al. The paper can be found here: . Our Comment points out that Schultz and co-authors ignored the fact that the results from satellite data obtained by Bell et al. were for a later time period than Schultz et al. examined, and that Bell et al. in fact also analyzed rainfall data for the same time period as Schultz et al. and, like them, also failed to find signs of a weekly cycle in rainfall during this time period. The contradictions claimed by Schultz et al. are non-existent. We point out some other problems with the methods and presentation by Schultz et al.

    Bridging the gap between low level ontologies used for data acquisition and high level ontologies used for inference is essential to enable the discovery of high-level links between low-level entities. This is of utmost importance in many applications, where the semantic distance between the observable evidence and the target relations is large. Examples of these applications would be detection of terrorist activity, crime analysis, and technology monitoring, among others. Currently this inference gap has been filled by expert knowledge. However, with the increase of the data and system size, it has become too costly to perform such manual inference. This paper proposes a semi-automatic system to bridge the inference gap using network correlation methods, similar to Bayesian Belief Networks, combined with hierarchical clustering, to group and organize data so that experts can observe and build the inference gap ontologies quickly and efficiently, decreasing the cost of this labor-intensive process. A simple application of this method is shown here, where the co-author collaboration structure ontology is inferred from the analysis of a collection of journal publications on the subject of anthrax. This example uncovers a co-author collaboration structures (a well defined ontology) from a scientific publication dataset (also a well defined ontology). Nevertheless, the evidence of author collaboration is poorly defined, requiring the use of evidence from keywords, citations, publication dates, and paper co-authorship. The proposed system automatically suggests candidate collaboration group patterns for evaluation by experts. Using an intuitive graphic user interface, these experts identify, confirm and refine the proposed ontologies and add them to the ontology database to be used in subsequent processes.

    superconducting material," said Peter Shternin of the Ioffe Institute in St Petersburg, Russia, leader of a team with a paper accepted in the journal Monthly Notices of the Royal Astronomical Society. Both teams show that this rapid cooling is explained by the formation of a neutron superfluid in the core of the neutron star within about the last 100 years as seen from Earth. The rapid cooling is expected to continue for a few decades and then it should slow down. "It turns out that Cas A may be a gift from the Universe because we would have to catch a very young neutron star at just the right point in time," said Page's co-author Madappa Prakash, from Ohio University. "Sometimes a little good fortune can go a long way in science." The onset of superfluidity in materials on Earth occurs at extremely low temperatures near absolute zero, but in neutron stars, it can occur at temperatures near a billion degrees Celsius. Until now there was a very large uncertainty in estimates of this critical temperature. This new research constrains the critical temperature to between one half a billion to just under a billion degrees. Cas A will allow researchers to test models of how the strong nuclear force, which binds subatomic particles, behaves in ultradense matter. These results are also important for understanding a range of behavior in neutron stars, including "glitches," neutron star precession and pulsation, magnetar outbursts and the evolution of neutron star magnetic fields. Small sudden changes in the spin rate of rotating neutron stars, called glitches, have previously given evidence for superfluid neutrons in the crust of a neutron star, where densities are much lower than seen in the core of the star. This latest news from Cas A unveils new information about the ultra-dense inner region of the neutron star. "Previously we had no idea how extended superconductivity of protons was in a neutron star," said Shternin's co-author Dmitry Yakovlev, also from the Ioffe Institute. The

    Galaxy. With the velocity information completed, the astronomers can now compute how the stars have wandered around in the Galaxy in the past, and where they will go in the future, cf. PR Video Clip 04/04. Birgitta Nordström, leader of the team, explains: "For the first time we have a complete set of observed stars that is a fair representation of the stellar population in the Milky Way disc in general. It is large enough for a proper statistical analysis and also has complete velocity and binary star information. We have just started the analysis of this dataset ourselves, but we know that our colleagues worldwide will rush to join in the interpretation of this treasure trove of information." The team's initial analysis indicates that objects like molecular clouds, spiral arms, black holes, or maybe a central bar in the Galaxy, have stirred up the motion of the stars throughout the entire history of the Milky Way disc. This in turn reveals that the evolution of the Milky Way was far more complex and chaotic than traditional, simplified models have long so far assumed. Supernova explosions, galaxy collisions, and infall of huge gas clouds have made the Milky Way a very lively place indeed!

    Background Although researchers have worked in collaboration since the origins of modern science and the publication of the first scientific journals in the eighteenth century, this phenomenon has acquired exceptional importance in the last several decades. Since the mid-twentieth century, new knowledge has been generated from within an ever-growing network of investigators, working cooperatively in research groups across countries and institutions. Cooperation is a crucial determinant of academic success. Objective The aim of the present paper is to analyze the evolution of scientific collaboration at the micro level, with regard to the scientific production generated on psoriasis research. Methods A bibliographic search in the Medline database containing the MeSH terms “psoriasis” or “psoriatic arthritis” was carried out. The search results were limited to articles, reviews and letters. After identifying the co-authorships of documents on psoriasis indexed in the Medline database (1942–2013), various bibliometric indicators were obtained, including the average number of authors per document and degree of multi-authorship over time. In addition, we performed a network analysis to study the evolution of certain features of the co-authorship network as a whole: average degree, size of the largest component, clustering coefficient, density and average distance. We also analyzed the evolution of the giant component to characterize the changing research patterns in the field, and we calculated social network indicators for the nodes, namely betweenness and closeness. Results The main active research clusters in the area were identified, along with their authors of reference. Our analysis of 28,670 documents sheds light on different aspects related to the evolution of scientific collaboration in the field, including the progressive increase in the mean number of co-authors (which stood at 5.17 in the 2004–2013 decade), and the rise in multi-authored papers

    Hundreds of millions of figures are available in biomedical literature, representing important biomedical experimental evidence. This ever-increasing sheer volume has made it difficult for scientists to effectively and accurately access figures of their interest, the process of which is crucial for validating research facts and for formulating or testing novel research hypotheses. Current figure search applications can't fully meet this challenge as the “bag of figures” assumption doesn't take into account the relationship among figures. In our previous study, hundreds of biomedical researchers have annotated articles in which they serve as corresponding authors. They ranked each figure in their paper based on a figure's importance at their discretion, referred to as “figure ranking”. Using this collection of annotated data, we investigated computational approaches to automatically rank figures. We exploited and extended the state-of-the-art listwise learning-to-rank algorithms and developed a new supervised-learning model BioFigRank. The cross-validation results show that BioFigRank yielded the best performance compared with other state-of-the-art computational models, and the greedy feature selection can further boost the ranking performance significantly. Furthermore, we carry out the evaluation by comparing BioFigRank with three-level competitive domain-specific human experts: (1) First Author, (2) Non-Author-In-Domain-Expert who is not the author nor co-author of an article but who works in the same field of the corresponding author of the article, and (3) Non-Author-Out-Domain-Expert who is not the author nor co-author of an article and who may or may not work in the same field of the corresponding author of an article. Our results show that BioFigRank outperforms Non-Author-Out-Domain-Expert and performs as well as Non-Author-In-Domain-Expert. Although BioFigRank underperforms First Author, since most biomedical researchers are either in- or out
