ABSTRACT
Using the science verification data of the Dark Energy Survey for a new sample of 106 X-ray selected clusters and groups, we study the stellar mass growth of bright central galaxies (BCGs) since redshift z ~ 1.2. Compared with the expectation in a semi-analytical model applied to the Millennium Simulation, the observed BCGs become under-massive/under-luminous with decreasing redshift. We incorporate the uncertainties associated with cluster mass, redshift, and BCG stellar mass measurements into an analysis of a redshift-dependent BCG-cluster mass relation,

, and compare the observed relation to the model prediction. We estimate the average growth rate since z = 1.0 for BCGs hosted by clusters of M
200,z
= 1013.8
M
⊙; at z = 1.0: m
*,BCG appears to have grown by 0.13 ± 0.11 dex, in tension at the ∼2.5σ significance level with the 0.40 dex growth rate expected from the semi-analytic model. We show that the build-up of extended intracluster light after z = 1.0 may alleviate this tension in BCG growth rates.
Observations sur le sarcophage de Polyxène et les styles de l’Ionie du Nord à la fin de l’archaïsme
Authors: Croissant Francis 
Published: January 2016

Le sarcophage en marbre dit « de Polyxène », trouvé en 1994 près de Gümüsçay en Turquie, s’il a été déjà assez souvent commenté, n’a encore fait l’objet d’aucune publication exhaustive. Il constitue pourtant un document majeur sur l’art grec de la fin de l’archaïsme et pose des problèmes difficiles, notamment du point de vue de l’iconographie, qui a jusqu’à présent surtout retenu l’attention. Mais les questions de style ne sont pas moins cruciales, même s’il a fallu attendre 2007 pour qu’un article leur soit spécialement consacré. Encore cette étude, qui comporte pour la première fois une illustration complète, et replace à juste titre les reliefs dans le cadre régional tracé en 1975 par le dernier livre d’Ernst Langlotz, c’est‑à‑dire l’Ionie du Nord, laisse‑t‑elle de côté quelques aspects essentiels du monument : les affinités évidentes de celui‑ci avec la peinture attique de la fin du vi e s., notamment, et la diversité interne que fait vite apparaître un examen attentif des visages appellent une explication. Or l’analyse comparative des profils conduit à y retrouver les trois principaux modèles stylistiques — créés selon toute apparence à Phocée, à Clazomènes et en Éolide — qu’avait mis en évidence dès 1983 l’étude des protomés féminines de terre cuite. Il est donc probable que l’atelier qui, vers 520 av. J.‑C., vint sur les rives de la Propontide exécuter la commande d’un membre de l’élite locale réunissait, autour d’un maître d’œuvre sans doute clazoménien, plusieurs sculpteurs de la région. Ainsi se trouve brillamment confirmée la vitalité de ces centres de création de l’Ionie du Nord, dont les protomés permettaient déjà de supposer qu’ils avaient joué parallèlement, par l’intermédiaire d’artistes immigrés, un rôle majeur dans l’évolution de l’art attique, notamment dans la naissance et le développement de la peinture à figures rouges.
Les dynamiques de Jean-Jacques Dortous de Mairan
Authors: Schmit Christophe 
Published: January 2016

Ellen McNiven Hine montre l’influence qu’exercent les théories de Newton sur Jean-Jacques Dortous de Mairan et tempère l’image donnée par des travaux antérieurs faisant de ce savant un fidèle disciple de René Descartes : elle qualifie alors l’académicien de « cartonian ». Par ailleurs, la bibliothèque de Mairan s’avère riche d’ouvrages aux inspirations scientifiques diverses, laissant supposer une curiosité, voire une pratique, débordant le cadre d’une doxa cartésienne. À travers l’examen de quelques éléments du système du monde proposé par Dortous de Mairan, ainsi qu’à l’aune de ses réflexions sur l’inertie et sur la cohésion de la matière, cette étude vise dans un premier temps à justifier que le qualificatif « cartésien » ne rend qu’insuffisamment compte du mécanisme adopté par Mairan : si, en suivant la thèse de McNiven Hine, Mairan n’est plus tout à fait « cartésien » du fait de l’influence d’Isaac Newton, il s’éloigne aussi de Descartes de par sa lecture de Nicolas Malebranche. L’étude s’attache par ailleurs aux analyses de Mairan relatives à la quantification de la force d’un corps en mouvement, et à celles touchant à des collisions de mobiles sur des surfaces fixes : ces premiers travaux montrent la diversité d’usage du mot « force », qui correspond à un simple mouvement et/ou à une impulsion ; les seconds s’inscrivent dans des pratiques qui préfigurent la formulation du principe de D’Alembert.
Les « vertus épistémiques » : un champ de problèmes crucial pour les sciences de l’éducation
Authors: Charbonnier Sébastien 
Published: January 2016

Résumé Depuis une vingtaine d’années, un champ nouveau de problèmes émerge dans la recherche philosophique anglophone : l’épistémologie des vertus ( Virtue Epistemology ). Il s’agit de questionner le problème des qualités personnelles nécessaires pour parvenir au vrai, ou du moins pour effectuer une recherche intellectuelle. De tels problèmes transversaux entre l’épistémologie et l’éthique concernent directement les problèmes éducatifs et pédagogiques. S’y déploie un véritable trésor conceptuel que la recherche en sciences de l’éducation gagnerait à connaître : nombre de faux problèmes et de débats stériles s’écroulent lorsqu’on ne considère plus séparément les questions épistémiques (conditions de compréhension rationnelle d’une idée par un individu) et les questions éthiques (conditions émotionnelles et affectives qui permettent une disposition favorable aux apprentissages – qui supposent capacité à s’étonner, patience, écoute de l’autre, etc.).
De la sauvegarde de la justice à la sauvegarde du magistrat : Une impossible objectivation des critères restreignant la liberté d’expression ?
Authors: Baudot Jean-Baptiste , Larre Floriane , Schornstein Coraline 
Published: January 2016

La liberté d’expression, garantie par l’article 11 de la Déclaration des droits de l’Homme de 1789 et par l’article 10 de la Convention européenne des droits de l’Homme (CEDH), est affirmée comme étant à la fois essentielle dans toute société démocratique1 – elle préserve le pluralisme des idées et des opinions – et matricielles – car de nombreux droits et libertés sont réputés en découler telles que la liberté de la presse2, la liberté artistique3, etc. Toutefois, cette liberté n’est pas inconditionnelle. Elle peut être limitée par d’autres libertés de valeur constitutionnelle ou conventionnelle. Ainsi, parce que l’autorité judiciaire est également un pilier de la démocratie, l’outrage à magistrat dans l’exercice de ses fonctions (articles 433-5 et 434-25 du code pénal) et l’atteinte portée au respect dû à l’autorité et à l’indépendance de la justice (articles 434-25 et 434-44 du code pénal) font partie de ces restrictions possibles. C’est ce que rappelle l’arrêt de la Cour d’appel de Paris, du 22 octobre 2015 qui condamne Henri Guaino, député des Yvelines, pour outrage à magistrat dans l’exercice de ses fonctions.

Geometric Numerical Integration for Peakon b-Family Equations
Authors: Cai Wenjun , Sun Yajuan , Wang Yushun 
Published: January 2016

AbstractIn this paper, we study the Camassa-Holm equation and the Degasperis-Procesi equation. The two equations are in the family of integrable peakon equations, and both have very rich geometric properties. Based on these geometric structures, we construct the geometric numerical integrators for simulating their soliton solutions. The Camassa-Holm equation and the Degasperis-Procesi equation have many common properties, however they also have the significant difference, for example there exist the shock wave solutions for the Degasperis-Procesi equation. By using the symplectic Fourier pseudo-spectral integrator, we simulate the peakon solutions of the two equations. To illustrate the smooth solitons and shock wave solutions of the DP equation, we use the splitting technique and combine the composition methods. In the numerical experiments, comparisons of these two kinds of methods are presented in terms of accuracy, computational cost and invariants preservation.
A New Coupled Complex Boundary Method for Bioluminescence Tomography
Authors: Gong Rongfang , Cheng Xiaoliang , Han Weimin 
Published: January 2016

AbstractIn this paper, we introduce and study a new method for solving inverse source problems, through a working model that arises in bioluminescence tomography (BLT). In the BLT problem, one constructs quantitatively the bioluminescence source distribution inside a small animal from optical signals detected on the animal's body surface. The BLT problem possesses strong ill-posedness and often the Tikhonov regularization is used to obtain stable approximate solutions. In conventional Tikhonov regularization, it is crucial to choose a proper regularization parameter for trade off between the accuracy and stability of approximate solutions. The new method is based on a combination of the boundary condition and the boundary measurement in a parameter-dependent single complex Robin boundary condition, followed by the Tikhonov regularization. By properly adjusting the parameter in the Robin boundary condition, we achieve two important properties for our new method: first, the regularized solutions are uniformly stable with respect to the regularization parameter so that the regularization parameter can be chosen based solely on the consideration of the solution accuracy; second, the convergence order of the regularized solutions reaches one with respect to the noise level. Then, the finite element method is used to compute numerical solutions and a new finite element error estimate is derived for discrete solutions. These results improve related results found in the existing literature. Several numerical examples are provided to illustrate the theoretical results.
A Front Tracking Method for the Simulation of Compressible Multimedium Flows
Authors: Lu Haitian , Zhao Ning , Wang Donghong 
Published: January 2016

AbstractA front tracking method combined with the real ghost fluid method (RGFM) is proposed for simulations of fluid interfaces in two-dimensional compressible flows. In this paper the Riemann problem is constructed along the normal direction of interface and the corresponding Riemann solutions are used to track fluid interfaces. The interface boundary conditions are defined by the RGFM, and the fluid interfaces are explicitly tracked by several connected marker points. The Riemann solutions are also used directly to update the flow states on both sides of the interface in the RGFM. In order to validate the accuracy and capacity of the new method, extensive numerical tests including the bubble advection, the Sod tube, the shock-bubble interaction, the Richtmyer-Meshkov instability and the gas-water interface, are simulated by using the Euler equations. The computational results are also compared with earlier computational studies and it shows good agreements including the compressible gas-water system with large density differences.

Published: January 2016

Abstract
Etching of hydrogenated amorphous carbon (a-C:H) films in 0.1 M nitric acid was evaluated using surface plasmon resonance at the applied voltages of 0.0, −1.0, and 1.0 V. The etching rates of the a-C:H films as functions of the applied voltages and etching duration were obtained to be 0.0368 (at 0.0 V), 0.0117 (at −1.0 V), and 0.0074 nm/min (at 1.0 V). These results clearly indicate that the etching rates decrease significantly under the conditions of applying positive or negative voltage, demonstrating the enhanced corrosion resistance of the a-C:H films upon applying voltage.
Leadership Behaviors and Its Relation with Principals’ Management Experience
Authors: Mehdinezhad Vali , Sardarzahi Zaid 
Published: January 2016

Abstract
This paper aims at studying the leadership behaviors reported by principals and observed by teachers and its relationship with management experience of principals. A quantitative method was used in this study. The target population included all principals and teachers of guidance schools and high schools in the Dashtiari District, Iran. A sample consisting of 46 principals and 129 teachers was selected by stratified sampling and simple random sampling methods. A leadership Behavior Description Questionnaire (LBDQ) developed by Kozes and Posner (2001) was used for data collection. The obtained data were analyzed using one sample and independent t-test, correlation coefficient and crosstabs pearson Chi-square test. The results showed that teachers describe leadership behaviors of their principals relatively well. However, principals themselves evaluated their leadership behaviors as very well. Comparing between leadership behaviors self-reported by principals and those observed by teachers, a significant difference was found between the views and evaluations of teachers and principals on all components of leadership behaviors of principals, except that regarding empowerment. In fact, principals described their leadership behaviors better and at a more appropriate level than teachers. From the perspective of both teachers and principals, there was no significant relationship between any of the components of leadership behaviors and management experience of principals.

AbstractIonospheric storms can have important effects on radio communications and navigation systems. Storm time ionospheric predictions have the potential to form part of effective mitigation strategies to these problems. Ionospheric storms are caused by strong forcing from the solar wind. Electron density enhancements are driven by penetration electric fields, as well as by thermosphere‐ionosphere behavior including Traveling Atmospheric Disturbances and Traveling Ionospheric Disturbances and changes to the neutral composition. This study assesses the effect on 1 h predictions of specifying initial ionospheric and thermospheric conditions using total electron content (TEC) observations under a fixed set of solar and high‐latitude drivers. Prediction performance is assessed against TEC observations, incoherent scatter radar, and in situ electron density observations. Corotated TEC data provide a benchmark of forecast accuracy. The primary case study is the storm of 10 September 2005, while the anomalous storm of 21 January 2005 provides a secondary comparison. The study uses an ensemble Kalman filter constructed with the Data Assimilation Research Testbed and the Thermosphere Ionosphere Electrodynamics General Circulation Model. Maps of preprocessed, verticalized GPS TEC are assimilated, while high‐latitude specifications from the Assimilative Mapping of Ionospheric Electrodynamics and solar flux observations from the Solar Extreme Ultraviolet Experiment are used to drive the model. The filter adjusts ionospheric and thermospheric parameters, making use of time‐evolving covariance estimates. The approach is effective in correcting model biases but does not capture all the behavior of the storms. In particular, a ridge‐like enhancement over the continental USA is not predicted, indicating the importance of predicting storm time electric field behavior to the problem of ionospheric forecasting.
Surface slip during large Owens Valley earthquakes

Published: January 2016

AbstractThe 1872 Owens Valley earthquake is the third largest known historical earthquake in California. Relatively sparse field data and a complex rupture trace, however, inhibited attempts to fully resolve the slip distribution and reconcile the total moment release. We present a new, comprehensive record of surface slip based on lidar and field investigation, documenting 162 new measurements of laterally and vertically displaced landforms for 1872 and prehistoric Owens Valley earthquakes. Our lidar analysis uses a newly developed analytical tool to measure fault slip based on cross‐correlation of sublinear topographic features and to produce a uniquely shaped probability density function (PDF) for each measurement. Stacking PDFs along strike to form cumulative offset probability distribution plots (COPDs) highlights common values corresponding to single and multiple‐event displacements. Lateral offsets for 1872 vary systematically from ∼1.0 to 6.0 m and average 3.3 ± 1.1 m (2σ). Vertical offsets are predominantly east‐down between ∼0.1 and 2.4 m, with a mean of 0.8 ± 0.5 m. The average lateral‐to‐vertical ratio compiled at specific sites is ∼6:1. Summing displacements across subparallel, overlapping rupture traces implies a maximum of 7–11 m and net average of 4.4 ± 1.5 m, corresponding to a geologic Mw∼7.5 for the 1872 event. We attribute progressively higher‐offset lateral COPD peaks at 7.1 ± 2.0 m, 12.8 ± 1.5 m, and 16.6 ± 1.4 m to three earlier large surface ruptures. Evaluating cumulative displacements in context with previously dated landforms in Owens Valley suggests relatively modest rates of fault slip, averaging between ∼0.6 and 1.6 mm/yr (1σ) over the late Quaternary.
Stable and clumped isotopes in shell carbonates of land snails Cathaica sp. and Bradybaena sp. in north China and implications for ecophysiological characteristics and paleoclimate studies
Authors: Wang Xu , Cui Linlin , Zhai Jixuan , Ding Zhongli 
Published: January 2016

AbstractKnowledge of ecophysiological characteristics of different land snail species is crucial for defining climatic significance of snail faunal assemblages. However, little work has been done in this aspect, hindering our obtaining unambiguous paleoclimatic information using these proxy indicators. Here we document for the first time the different ecophysiological characteristics of Cathaica sp. and Bradybaena sp. land snails using the stable isotopes and clumped isotope (Δ47) of the shell carbonates. The Δ47‐derived temperatures for both species revealed a robust correlation with environmental temperatures. Moreover, the temperatures for Cathaica sp. are 3–5°C higher than those for Bradybaena sp. land snails, indicating different ecophysiological adaptations or growing seasons of the two species. Specifically, Cathaica sp. snails prefer living in a warm‐humid summer, whereas Bradybaena sp. snails are active in the relatively cool‐arid spring and/or autumn. The result testifies to the Δ47 in snail shell carbonates as a promising paleothermometer in monsoonal region and presents new insight into paleoclimatic explanation of these land snail species. This finding highlights the importance of climatic seasonality in the changes of the faunal assemblages of land snails.
Coherence and phase structure of compressional ULF waves at low‐Earth orbit observed by the Swarm satellites
Authors: Heilig B. , Sutcliffe P. R. 
Published: January 2016

AbstractIn this paper we present results of a study of Pc3 compressional waves observed at low‐Earth orbit (LEO) by the Swarm satellites. The particular emphasis has been to investigate the distribution of wave coherence and phase difference as functions of magnetic latitude and local time. This is the first time that a study of this nature has been carried out using magnetic field data from multiple LEO satellites. We have also for the first time shown how our analysis technique can be used to discriminate between static spatial and simultaneous temporal wave structures observed in the ionosphere. We believe that our study provides the first observational evidence to support the prediction by the inductive thin ionosphere model that incident Alfvén mode waves are partially converted into compressional mode waves by the ionosphere.
The Bolivian, Botswana, and Bilybara Highs and Southern Hemisphere drought/floods
Authors: Reason C. J. C. 
Published: January 2016

AbstractSemipermanent anticyclones in the midlevel troposphere over the subtropical landmasses are a prominent component of Southern Hemisphere climate. Typically, they occur over Bolivia, Botswana/Namibia, and northwestern Australia from austral spring to about April and are strongest in late summer. Here a mode of variability is studied that modulates the strength of these midlevel anticyclones and which is not strongly tied to El Niño–Southern Oscillation. This mode leads to variations in January–March rainfall over large parts of South America, southern Africa, and Australia on both interannual and near‐decadal scales.
