The development of supergravity grand unification: Circa 1982 1985
No full textThe development in the early eighties of supergravity grand unified models with gravity-mediated breaking of supersymmetry has led to a remarkable progress in the study of supersymmetry at colliders, in dark matter and in a variety of other experimental searches in the intervening years since that time. The purpose of this note is to review this development and describe our construction of this theory in the period 1982-1985. © 2012 World Scientific Publishing Company.Aad G, 2012, PHYS LETT B, V716, P1, DOI 10.1016-j.physletb.2012.08.020; Ahmed Z, 2010, SCIENCE, V327, P1619, DOI 10.1126-science.1186112; Ahmed Z, 2009, PHYS REV LETT, V102, DOI 10.1103-PhysRevLett.102.011301; Akula S, 2012, PHYS REV D, V85, DOI 10.1103-PhysRevD.85.075001; ALVAREZGAUME L, 1983, NUCL PHYS B, V221, P495, DOI 10.1016-0550-3213(83)90591-6; Aprile E., ARXIV11042549ASTROPH; ARNOWITT R, 1983, PHYS REV LETT, V50, P232, DOI 10.1103-PhysRevLett.50.232; ARNOWITT R, 1985, PHYS LETT B, V156, P215, DOI 10.1016-0370-2693(85)91512-6; ARNOWITT R, 1992, PHYS REV LETT, V69, P725, DOI 10.1103-PhysRevLett.69.725; Arnowitt R., 1962, GRAVITATION INTRO CU; Arnowitt R, 2008, PHYS REV LETT, V100, DOI 10.1103-PhysRevLett.100.231802; ARNOWITT R, 1975, PHYS LETT B, VB 56, P81, DOI 10.1016-0370-2693(75)90504-3; Arnowitt R.

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Solution of Raman-Nath equations
No full textAbstract
A function of 4 variables is defined, which is the solution of the Raman-Nath equations. These are a system of infinite coupled differential equations used to describe the diffraction of light from acoustic waves (or thick gratings), or in the theory of the free electron laser, or the interaction of radiation with multilevel systems. It can be adapted to more general cases (electrons or X-rays in crystals, calculation of Mathieu functions).
Title of program: RANA
Catalogue Id: ACNM_v1_0
Nature of problem
Evolution of a wave in a sinusoidal potential. In particular, diffraction of a wave from a thick sinusoidal grating or acoustic wave. Also used in the theory of the free electron laser and in interaction of radiation with multilevel material system.

Growth and liver histology of Channa punctatus exposed to a common biofertilizer
No full textMustard oil cake (MOC) is widely used as biofertilizer in the field of agriculture and aquaculture. Channa punctatus was exposed to 0.42 g.L−1 sublethal concentration for 4, 7, 14, 21 and 28 days. Due to such exposure, body growth and histological changes in liver were observed. It was revealed that weight, length and breadth of fish were gradually increased with the days of exposure in compare to control fish, whereas, liver showed an increase in sinusoidal space and lipidosis during early days, followed by a recovery from the stress of MOC on the 28th day
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.

A polymorphism in the <i>nath-10</i> gene explains the largest effect QTL.
No full text<p>(A) Fine-mapping of the QTL to a 183 kb region (gray rectangle). Chromosome I genotypes of five near-isogenic lines (NILs) at SNP markers (triangles) are represented. Orange triangles, N2 alleles; blue, AB1. Their vulval index at 25.5°C is indicated below. Genetic distances are represented to scale along full black lines, but not outside. The vulval index is significantly lower in JU1613 compared to the other NILs (Mann-Whitney-Wilcoxon rank sum tests, <i>p</i><10<sup>−4</sup>, <i>n</i> = 30–42). (B) RNAi against <i>nath-10</i>. The significance of pairwise Mann-Whitney-Wilcoxon rank sum tests comparing the <i>nath-10</i> RNAi versus control bacteria is represented above each pair of bars (<i>n</i> = 51–64). Combined <i>p</i> values of replicates using Fisher's method is indicated above. (C) Overexpression of N2 and AB1 <i>nath-10</i> alleles. Worms that spontaneously lost the transgene (gray) were compared to sibling worms that retained it (red). Black bars represent non-injected strains. Two replicates were scored per injected strain and allele (<i>n</i> = 36–45). Pairwise comparisons using Mann-Whitney-Wilcoxon rank sum tests were only significant in one case. However, combining the results using Fisher's method (top) showed a significant effect of each allele when injected into JU605, but not into JU1620. (D) Introgression of the <i>nath-10</i> allele from LSJ1 into N2. The vulval index of JU606, JU1610, and JU2000 was compared to N2 in two replicate experiments using Mann-Whitney-Wilcoxon rank sum tests. (B–D) Vulval phenotypes were scored in animals grown at 25.5°C. ns, non-significant, * 0.01<<i>p</i><0.05, *** <i>p</i><0.001. Strain genotypes are schematized below the graphs, with orange for N2 and blue for AB1 background. Orange and blue horizontal lines on chromosome I represent <i>nath-10</i> alleles and the red line on chromosome II <i>let-23(sy1)</i>. Only one chromosome copy is shown (the strains are rendered homozygous through selfing).</p
