Unconventional phase transitions in liquid crystals
Authors: Kats E I 
Published: January 2017

Abstract
According to classical textbooks on thermodynamics or statistical physics, there are only two types of phase transitions: continuous, or second-order, in which the latent heat L is zero, and first-order, in which L ≠ 0. Present-day textbooks and monographs also mention another, stand-alone type—the Berezinskii–Kosterlitz–Thouless transition, which exists only in two dimensions and shares some features with first- and second-order phase transitions. We discuss examples of non-conventional thermodynamic behavior (i.e., which is inconsistent with the theoretical phase transition paradigm now universally accepted). For phase transitions in smectic liquid crystals, mechanisms for nonconventional behavior are proposed and the predictions they imply are examined.
Development, characterization, and cross‐amplification of microsatellite markers in the understudied African genus Anthonotha (Fabaceae)
Authors: Demenou Boris B. , Hardy Olivier J. 
Published: January 2017

Premise of the study:Anthonotha macrophylla (Fabaceae) is a common tree species throughout the Guineo‐Congolian forest that is sometimes confounded with other congeneric species; it is expected to be an interesting phylogeographical model to infer the history of the African dense forests. We developed 18 microsatellite markers from this species and tested their transferability in 15 congeneric species.Methods and Results:A genomic library was obtained using the Illumina platform, and 18 polymorphic microsatellite loci were developed. The polymorphic microsatellites displayed two to 24 alleles (average: 11.9 alleles per locus, expected heterozygosity range: 0.18–0.91, mean: 0.64) in three populations of A. macrophylla from Benin, Liberia, and Cameroon. Cross‐amplification in one to nine individuals of 15 congeneric Anthonotha species (A. acuminata, A. brieyi, A. cladantha, A. crassifolia, A. ferruginea, A. fragrans, A. gilletii, A. lamprophylla, A. mouandzae, A. noldeae, A. pellegrinii, A. pynaertii, A. stipulacea, A. wijmacampensis, and A. xanderi) showed successful amplification in six to 17 loci, making most of these markers useful at the generic level.Conclusions:This set of markers will be useful to study species delimitation and the genetic structure of Anthonotha species, and thus to better understand the history of tropical African rainforests.
DIAGNOSTICS OF CORONAL HEATING IN ACTIVE-REGION LOOPS
Authors: Fludra A. , Hornsey C. , Nakariakov V. M. 
Published: January 2017

ABSTRACT
Understanding coronal heating remains a central problem in solar physics. Many mechanisms have been proposed to explain how energy is transferred to and deposited in the corona. We summarize past observational studies that attempted to identify the heating mechanism and point out the difficulties in reproducing the observations of the solar corona from the heating models. The aim of this paper is to study whether the observed extreme ultraviolet (EUV) emission in individual coronal loops in solar active regions can provide constraints on the volumetric heating function, and to develop a diagnostic for the heating function for a subset of loops that are found close to static thermal equilibrium. We reconstruct the coronal magnetic field from Solar Dynamics Observatory/HMI data using a nonlinear force-free magnetic field model. We model selected loops using a one-dimensional stationary model, with a heating rate dependent locally on the magnetic field strength along the loop, and we calculate the emission from these loops in various EUV wavelengths for different heating rates. We present a method to measure a power index β defining the dependence of the volumetric heating rate E

H
on the magnetic field,

, and controlling also the shape of the heating function: concentrated near the loop top, uniform and concentrated near the footpoints. The diagnostic is based on the dependence of the electron density on the index β. This method is free from the assumptions of the loop filling factor but requires spectroscopic measurements of the density-sensitive lines. The range of applicability for loops of different length and heating distributions is discussed, and the steps to solving the coronal heating problem are outlined.
SEARCHING FOR FOSSIL EVIDENCE OF AGN FEEDBACK IN WISE-SELECTED STRIPE-82 GALAXIES BY MEASURING THE THERMAL SUNYAEV–ZEL’DOVICH EFFECT WITH THE ATACAMA COSMOLOGY TELESCOPE

Published: January 2017

ABSTRACT
We directly measure the thermal energy of the gas surrounding galaxies through the thermal Sunyaev–Zel’dovich (tSZ) effect. We perform a stacking analysis of microwave background images from the Atacama Cosmology Telescope, around 1179 massive quiescent elliptical galaxies at 0.5 ≤ z ≤ 1.0 (“low-z”) and 3274 galaxies at 1.0 ≤ z ≤ 1.5 (“high-z”), selected using data from the Wide-field Infrared Survey Explorer All-Sky Survey and the Sloan Digital Sky Survey (SDSS) within the SDSS Stripe-82 field. The gas surrounding these galaxies is expected to contain energy from past episodes of active galactic nucleus (AGN) feedback, and after using modeling to subtract undetected contaminants, we detect a tSZ signal at a significance of

0.9
σ

for our low-z galaxies and

1.8
σ

for our high-z galaxies. We then include data from the high-frequency Planck bands for a subset of 227 low-z galaxies and 529 high-z galaxies and find low-z and high-z tSZ detections of

1.0
σ

and

1.5
σ

, respectively. These results indicate an average thermal heating around these galaxies of

THE AGE OF THE KIC 7177553 SYSTEM
Authors: MacDonald James , Mullan D. J. 
Published: January 2017

ABSTRACT
KIC 7177553 is a quadruple system containing two binaries of orbital periods 16.5 and 18 days. All components have comparable masses and are slowly rotating with spectral types of ∼G2V. The longer period binary is eclipsing with component masses and radii M
1 = 1.043 ± 0.014 M
⊙, R
1 = 0.940 ± 0.005 R
⊙ and M
2 = 0.986 ± 0.015 M
⊙, R
2 = 0.941 ± 0.005 R
⊙. The essentially equal radii measurements are inconsistent with the two stars being on the man sequence at the same age using standard nonmagnetic stellar evolution models. Instead a consistent scenario is found if the stars are in their pre-main-sequence phase of evolution and have an age of 32–36 Myr. We have also computed evolutionary models of magnetic stars, but we find that our nonmagnetic models fit the empirical radii and effective temperatures better than the magnetic models.

Background Access to combination antiretroviral therapy (cART) has decreased mortality in HIV-positive people. We aimed to estimate the expected additional years of life in HIV-positive Thai people after starting cART through the National AIDS Program (NAP), administered by the Thai National Health Security Office (NHSO). Methods The NHSO database collects characteristics of all Thai HIV-infected patients through the National AIDS Program, including linkage with the National Death Registry for vital status. This study included patients aged ≥15 years at cART initiation between 2008 and 2014. The abridged life table method was used to construct life tables stratified by sex and baseline CD4+ T-cell count. Life expectancy was defined as the additional years of life from age at starting cART. Results 201,688 eligible patients were included in analyses, contributing 618,837 person-years of follow-up. Median CD4+ T-cell count was 109 cells/mm3 and median age 37 years. The overall life expectancy after cART initiation at age 20 was 25.4 (95% CI, 25.3, 25.6) years and 20.6 (95% CI, 20.5, 20.7) at age 35 years. Life expectancy at baseline CD4+ T-cell count ≥350 cells/mm3 was 51.9 (95% CI, 51.0, 52.9) years for age 20 years and 43.2 (95% CI, 42.4, 44.1) years for age 35 years, close to life expectancy in the general Thai population. Conclusions Increasing life expectancy with higher baseline CD4+ T-cell counts supports the guideline recommendations to start cART irrespective of CD4+ T-cell count. These results are beneficial to forecast the treatment cost and develop health policies for people living with HIV in Thailand and Asia.
The Influence of the Relationship with the Superior on Newcomers’ Organizational Identification and Affective Commitment

Published: January 2017

Les organisations investissent fortement dans le processus de socialisation des nouveaux employés avec pour objectif la formation d’attitudes et de comportements souhaitables. Cependant, les facteurs qui en sont à l’origine restent relativement méconnus. Ainsi, si la littérature souligne le rôle du soutien social du supérieur, il n’existe, à notre connaissance, aucune étude portant sur l’influence du supérieur sur l’identification organisationnelle et l’engagement affectif des nouveaux salariés. Notre étude représente une méthodologie mixte reposant sur 20 entretiens et 335 questionnaires, est menée au sein d’un centre de formation de l’Armée de l’Air française auprès de jeunes sous-officiers. Elle souligne notamment le rôle de la compétence perçue du supérieur sur l’identification organisationnelle et l’implication affective des nouveaux salariés. Notre étude révèle également l’absence de relation directe entre la fiabilité du supérieur et l’implication affective des nouvelles recrues ; l’identification organisationnelle jouant le rôle de médiateur entre les deux variables. Enfin, elle établit l’existence d’une relation négative entre la justice interpersonnelle et l’identification organisationnelle des nouveaux employés.
Les dispositifs de validation et de reconnaissance des compétences acquises dans le cadre d’une mobilité : un révélateur de l’internationalisation du système de formation professionnelle en Allemagne
Authors: Krichewsky Léna 
Published: January 2017

Entre 2005 et 2015, la législation concernant la validation et la reconnaissance des compétences acquises dans le cadre d’un séjour à l’   étranger a profondément changé pour les apprentis allemands. Contrairement à la mobilité étudiante, la mobilité des apprentis de l’enseignement professionnel n’a longtemps fait l’objet que de peu d’intérêt de la part des employeurs et du milieu de la recherche. Sous l’impulsion du processus de Copenhague, mais également sous la pression des évolutions du marché du travail, le sujet n’a cependant cessé, depuis le début des années 2000, de gagner en importance. En 2011, une étude commanditée par l’Agence nationale allemande en charge d’Erasmus+ révélait l’ampleur de la mobilité internationale au sein de l’enseignement et de la formation professionnelle initiale et démontrait l’importance accordée, aussi bien par les entreprises que par les jeunes en formation, à la validation et à la reconnaissance des compétences acquises à l’   étranger. La présente contribution retrace l’   évolution de la législation en la matière, et propose d’en faire une lecture en termes d’internationalisation du curriculum de l’enseignement professionnel. La première partie présente un bref état de la recherche sur la mobilité internationale dans l’enseignement et la formation professionnelle en Allemagne, identifiant sur cette base les enjeux de la validation et de la reconnaissance des compétences du point de vue des entreprises et des apprentis. La seconde partie s’attache à décrire les différents dispositifs mis en place depuis 2005. La troisième partie propose un bilan des évolutions intervenues ces dix dernières années et questionne leur signification en termes d’internationalisation du système d’enseignement et de formation professionnelle.
Mobilité et compétence interculturelle dans les programmes internationaux d’apprentissage tout au long de la vie : une étude longitudinale
Authors: Giovanna Onorati Maria , Domenico d’Ovidio Francesco 
Published: January 2017

Une étude longitudinale sur le développement de la compétence interculturelle chez des étudiants de deux programmes intensifs, proposés dans la cadre du Programme d’éducation et de formation tout au long de la vie Erasmus, est ici présentée. Le modèle éducatif, fondé sur la mobilité internationale et sur un projet visant l’acquisition de com­pétences sociales et de communication spécifiques, favorisait l’acquisition de la compétence interculturelle et globale. L’   étude a été menée pendant six ans sur 196 étudiants participant pendant cette période à deux programmes intensifs consécutifs. Onze universités, de huit pays européens, y participaient. L’   objectif était le développement de compétences interculturelles chez des étudiants de diverses formations supérieures dans les universités partenaires. L’   analyse d’un questionnaire d’auto-évaluation a fourni une structure factorielle décrivant le caractère multidimensionnel et holistique de la compétence interculturelle, et son lien étroit avec l’expérience à l’international. Le modèle factoriel révèle que l’infrastructure sociale de la compétence interculturelle est un processus de sensibilisation au contexte et de développement d’une sociabilité inclusive. La mobilité n’agit pas directement sur la compétence, mais vient s’associer à des facteurs tels que l’utilisation du Web 2.0 comme outil didactique, et l’apprentissage par la pratique et collaboratif. Cela renvoie à la valorisation des apprentissages informels pour le développe­ment de compétences clés, comme prévu dans l’ECVET.

Abstract
Steroid receptor coactivator 3 (SRC-3) is a transcriptional coactivator that interacts with nuclear receptors and some other transcription factors to enhance their effects on target gene transcription. We reported previously that SRC-3–deficient (SRC-3−/−) mice are extremely susceptible to Escherichia coli–induced septic peritonitis as a result of uncontrolled inflammation and a defect in bacterial clearance. In this study, we observed significant upregulation of SRC-3 in colonic epithelial cells in response to Citrobacter rodentium infection. Based on these findings, we hypothesized that SRC-3 is involved in host defense against attaching and effacing bacterial infection. We compared the responses of SRC-3−/− and wild-type mice to intestinal C. rodentium infection. We found that SRC-3−/− mice exhibited delayed clearance of C. rodentium and more severe tissue pathology after oral infection with C. rodentium compared with wild-type mice. SRC-3−/− mice expressed normal antimicrobial peptides in the colons but exhibited delayed recruitment of neutrophils into the colonic mucosa. Accordingly, SRC-3−/− mice showed a delayed induction of CXCL2 and CXCL5 in colonic epithelial cells, which are responsible for neutrophil recruitment. At the molecular level, we found that SRC-3 can activate the NF-κB signaling pathway to promote CXCL2 expression at the transcriptional level. Collectively, we show that SRC-3 contributes to host defense against enteric bacteria, at least in part via upregulating CXCL2 expression to recruit neutrophils.
TCR Signaling and CD28/CTLA-4 Signaling Cooperatively Modulate T Regulatory Cell Homeostasis
Authors: Holt Michael P. , Punkosdy George A. , Glass Deborah D. , Shevach Ethan M. 
Published: January 2017

Abstract
Foxp3+ T regulatory cells (Tregs), conventional CD4+Foxp3− T cells, and CD8+ T cells represent heterogeneous populations composed of naive phenotype (NP, CD44low) and memory phenotype (MP, CD44high) subpopulations. NP and MP subsets differ in their activation state, contribution to immune function, and capacity to proliferate in vivo. To further understand the factors that contribute to the differential homeostasis of NP/MP subsets, we examined the differential effects of CD28 and CTLA-4 interaction with CD80/CD86, as well as MHC class II–TCR interaction within mouse Treg pools and CD4+ and CD8+ T cell pools. Blockade of CD80/CD86 with CTLA-4–Ig markedly reduced the cycling and absolute numbers of MP Tregs and MP CD4+ T cells, with minimal effect on the NP T cell subpopulations. Blockade of MHC class II–TCR interaction led to selective expansion of MP Tregs and MP CD4+ and CD8+ T cells that was reversed upon cotreatment with CTLA-4–Ig. Treatment with anti–CTLA-4 mAb altered MP Treg and MP CD4+ and CD8+ T cell homeostasis in a manner similar to that observed with anti–MHC class II. We postulate a complex pathway in which CD28 is the primary driver of Treg proliferation and CTLA-4 functions as the main brake but is likely dependent on TCR signals and CD80/CD86. These findings have important implications for the use of biologic agents targeting such pathways to modulate autoimmune and neoplastic disease.
Exploring the world of micro sculptures - subfossil Cladocera remains under the SEM
Authors: Zawiska Izabela , Zawisza Edyta , Wojewódka Marta , Sinev Artem Y. 
Published: January 2017

<p>The scanning electron microscope (SEM) is widely used for the identification of microstructural characteristics and morphology of different microorganisms. Common procedures are based and developed for remains of living species. This paper presents an effective method for drying and preparing subfossil Cladocera remains for SEM observation, which has been recently adapted and tested on several samples originating from different American and European lakes. This method results to be fast and cheap, as it excludes the use of expensive and toxic reagents. Moreover, it allows to recognize the micro sculpture and other species specific characteristics present on the different body parts of the Cladocera remains. The present contribution provides 29 high quality pictures of 12 cladoceran species at magnification between 200x and 11,000x. SEM images reveal that the patterns observed on the shells under the light microscope actually are always three dimensional structures.</p>
Inequalities for the Surface Area of Projections of Convex Bodies
Authors: Giannopoulos Apostolos , Koldobsky Alexander , Valettas Petros 
Published: January 2017

AbstractWe provide general inequalities that compare the surface area S(K) of a convex body K in ℝn to the minimal, average, or maximal surface area of its hyperplane or lower dimensional projections. We discuss the same questions for all the quermassintegrals of K. We examine separately the dependence of the constants on the dimension in the case where K is in some of the classical positions or K is a projection body. Our results are in the spirit of the hyperplane problem, with sections replaced by projections and volume by surface area.
Character Density in Central Subalgebras of Compact Quantum Groups
Authors: Alaghmandan Mahmood , Crann Jason 
Published: January 2017

AbstractWe investigate quantum group generalizations of various density results from Fourier analysis on compact groups. In particular, we establish the density of characters in the space of fixed points of the conjugation action on L2(𝔾) and use this result to show the weak* density and normdensity of characters in ZL∞(G) and ZC(G), respectively. As a corollary, we partially answer an open question of Woronowicz. At the level of L1(G), we show that the center Z(L1(G)) is precisely the closed linear span of the quantum characters for a large class of compact quantum groups, including arbitrary compact Kac algebras. In the latter setting, we show, in addition, that Z(L1(G)) is a completely complemented Z(L1(G))-submodule of L1(G).
Analysis of Tax Formation and Impact on Economic Growth in Nigeria
Authors: O.T Ebiringa, , Yadirichukwu Emeh 
Published: January 2017

As a fiscal instrument, direct taxes are used to adjust people’s disposable income and to reduce the parameter of unearned incomes. At the macroeconomic level, taxes are used to redistribute income and therefore contribute to the economic growth of the country. This paper examines the empirical forms of tax on the economic growth in Nigeria. Secondary data were sourced within the periods of 1985-2011 and Model was specified and estimated using some econometric. The result showed that the determinant factor of economic growth in the country through tax, only custom and exercise duties is capable of influencing but has an inverse relationship and significant to the GDP. It is observed that economic instability were experienced between 1986-1987 and 1993 to 1995 but evident in the stability in the economic growth from the graph in the rest of the years of the study around bench mark value of zero line of the GDP predicted graph based on tax generations in Nigeria. The study therefore recommended that the company income tax system should be generally restructured to bring about more yielded revenue results capable of contributing more significantly to the Nigerian economic as it is done in the advanced countries of the world. Custom service operations and revenue generations in the border is not practically reflected in the economy due to no accountability, transparency and leakages in the system.
