A GLOBAL VIEW OF VELOCITY FLUCTUATIONS IN THE CORONA BELOW 1.3 R⊙ WITH CoMP
Authors: Morton R. J. , Tomczyk S. , Pinto R. F. 
Published: September 2016

ABSTRACT
The Coronal Multi-channel Polarimeter (CoMP) has previously demonstrated the presence of Doppler velocity fluctuations in the solar corona. The observed fluctuations are thought to be transverse waves, i.e., highly incompressible motions whose restoring force is dominated by the magnetic tension, some of which demonstrate clear periodicity. We aim to exploit CoMP’s ability to provide high cadence observations of the off-limb corona to investigate the properties of velocity fluctuations in a range of coronal features, providing insight into how (whether) the properties of the waves are influenced by the varying magnetic topology in active regions, quiet Sun and open field regions. An analysis of Doppler velocity time-series of the solar corona from the 10747 Å Iron xiii line is performed, determining the velocity power spectrum and using it as a tool to probe wave behavior. Further, the average phase speed and density for each region are estimated and used to compute the spectra for energy density and energy flux. In addition, we assess the noise levels associated with the CoMP data, deriving analytic formulae for the uncertainty on Doppler velocity measurements and providing a comparison by estimating the noise from the data. It is found that the entire corona is replete with transverse wave behavior. The corresponding power spectra indicate that the observed velocity fluctuations are predominately generated by stochastic processes, with the spectral slope of the power varying between the different magnetic regions. Most strikingly, all power spectra reveal the presence of enhanced power occurring at ∼3 mHz, potentially implying that the excitation of coronal transverse waves by p-modes is a global phenomenon.
HELIUM REIONIZATION SIMULATIONS. I. MODELING QUASARS AS RADIATION SOURCES
Authors: La Plante Paul , Trac Hy 
Published: September 2016

ABSTRACT
We introduce a new project to understand helium reionization using fully coupled N-body, hydrodynamics, and radiative transfer simulations. This project aims to capture correctly the thermal history of the intergalactic medium as a result of reionization and make predictions about the Lyα forest and baryon temperature–density relation. The dominant sources of radiation for this transition are quasars, so modeling the source population accurately is very important for making reliable predictions. In this first paper, we present a new method for populating dark matter halos with quasars. Our set of quasar models includes two different light curves, a lightbulb (simple on/off) and symmetric exponential model, and luminosity-dependent quasar lifetimes. Our method self-consistently reproduces an input quasar luminosity function given a halo catalog from an N-body simulation, and propagates quasars through the merger history of halo hosts. After calibrating quasar clustering using measurements from the Baryon Oscillation Spectroscopic Survey, we find that the characteristic mass of quasar hosts is

for the lightbulb model, and

for the exponential model. In the latter model, the peak quasar luminosity for a given halo mass is larger than that in the former, typically by a factor of 1.5–2. The effective lifetime for quasars in the lightbulb model is 59 Myr, and in the exponential case, the effective time constant is about 15 Myr. We include semi-analytic calculations of helium reionization, and discuss how to include these quasars as sources of ionizing radiation for full hydrodynamics with radiative transfer simulations in order to study helium reionization.

ABSTRACT
Many powerful and variable gamma-ray sources, including pulsar wind nebulae, active galactic nuclei and gamma-ray bursts, seem capable of accelerating particles to gamma-ray emitting energies efficiently over very short timescales. These are likely due to the rapid dissipation of electromagnetic energy in a highly magnetized, relativistic plasma. In order to understand the generic features of such processes, we have investigated simple models based on the relaxation of unstable force-free magnetostatic equilibria. In this work, we make the connection between the corresponding plasma dynamics and the expected radiation signal, using 2D particle-in-cell simulations that self-consistently include synchrotron radiation reactions. We focus on the lowest order unstable force-free equilibrium in a 2D periodic box. We find that rapid variability, with modest apparent radiation efficiency as perceived by a fixed observer, can be produced during the evolution of the instability. The “flares” are accompanied by an increased polarization degree in the high energy band, with rapid variation in the polarization angle. Furthermore, the separation between the acceleration sites and the synchrotron radiation sites for the highest energy particles facilitates acceleration beyond the synchrotron radiation reaction limit. We also discuss the dynamical consequences of the radiation reaction, and some astrophysical applications of this model. Our current simulations with numerically tractable parameters are not yet able to reproduce the most dramatic gamma-ray flares, e.g., from the Crab Nebula. Higher magnetization studies are promising and will be carried out in the future.

High-resolution monitoring of nutrients in groundwater and surface waters: process understanding, quantification of loads and concentrations, and management applications
Authors: van Geer Frans C. , Kronvang Brian , Broers Hans Peter 
Published: September 2016

Abstract. Four sessions on "Monitoring Strategies: temporal trends in groundwater and surface water quality and quantity" at the EGU conferences in 2012, 2013, 2014, and 2015 and a special issue of HESS form the background for this overview of the current state of high-resolution monitoring of nutrients. The overview includes a summary of technologies applied in high-frequency monitoring of nutrients in the special issue. Moreover, we present a new assessment of the objectives behind high-frequency monitoring as classified into three main groups: (i) improved understanding of the underlying hydrological, chemical, and biological processes (PU); (ii) quantification of true nutrient concentrations and loads (Q); and (iii) operational management, including evaluation of the effects of mitigation measures (M). The contributions in the special issue focus on the implementation of high-frequency monitoring within the broader context of policy making and management of water in Europe for support of EU directives such as the Water Framework Directive, the Groundwater Directive, and the Nitrates Directive. The overview presented enabled us to highlight the typical objectives encountered in the application of high-frequency monitoring and to reflect on future developments and research needs in this growing field of expertise.

Published: September 2016

Abstract. Along a traverse through North Greenland in May 2015 we collected snow cores up to 2 m depth and analyzed their density and water isotopic composition. A new sampling technique and an adapted algorithm for comparing data sets from different sites and aligning stratigraphic features are presented. We find good agreement of the density layering in the snowpack over hundreds of kilometers, which allows the construction of a representative density profile. The results are supported by an empirical statistical density model, which is used to generate sets of random profiles and validate the applied methods. Furthermore we are able to calculate annual accumulation rates, align melt layers and observe isotopic temperatures in the area back to 2010. Distinct relations of δ18O with both accumulation rate and density are deduced. Inter alia the depths of the 2012 melt layers and high-resolution densities are provided for applications in remote sensing.
De compte-fil à garde-fou : la lecture du traducteur de poésie
Authors: Stratford Madeleine 
Published: September 2016

Plusieurs représentants de la tradition herméneutique, dont Umberto Eco, Paul Ricoeur et George Steiner, considèrent le texte littéraire inachevé sans le concours du lecteur, lequel est cependant tenu d’en respecter la cohérence interne. Dans un tel contexte, l’affirmation selon laquelle le traducteur serait d’abord un lecteur constitue une évidence qui recèle, en soi, de multiples implications. Dans cet article, nous verrons d’abord comment l’oeuvre littéraire conditionne la lecture et, par conséquent, la traduction pour nous pencher ensuite sur la tension que présuppose la lecture d’un poème à traduire. Pour ce faire, nous comparerons cinq modèles décrivant le processus de traduction poétique des théoriciens suivants : Robert De Beaugrande, Andrei Banta&scedil;, Francis R. Jones, Christopher Millis et Robert Bly. Ceux-ci s’inscrivent, selon nous, dans la lignée herméneutique en ceci qu’ils préconisent une lecture attentive du poème source, mais cherchent à en contrebalancer les effets par une révision obligatoire minimisant l’apport subjectif du traducteur. L’analyse de ces modèles permettra de constater l’importance réelle de la lecture dans la tâche du traducteur de poésie.
La relecture unilingue : une procédure de révision de traduction rapide, fonctionnelle, mais déloyale
Authors: Robert Isabelle S. 
Published: September 2016

Depuis 2006, les agences de traduction européennes qui souhaitent travailler conformément à la norme EN 15038 sur les services de traduction doivent intégrer la révision dans leur processus. Toutefois, la norme n’est pas claire quant à la manière dont cette révision doit être effectuée et en particulier quant à la nécessité de comparer les textes source et cible durant la révision. Ce constat est à la base d’une étude en cours devant déterminer l’impact de la procédure de révision sur le produit et le processus de révision. Dans la présente contribution, une procédure de révision non comparative, la relecture unilingue, sera comparée à trois autres procédures : la relecture bilingue et deux relectures dites « doubles », à savoir la relecture bilingue suivie d’une relecture unilingue et la relecture unilingue suivie d’une relecture bilingue. L’objectif est de déterminer si la relecture unilingue est efficace et, le cas échéant, dans quelles conditions et par rapport à quelle autre procédure. Pour ce faire, les scores de seize réviseurs professionnels ayant révisé quatre textes cibles comparables chaque fois selon une procédure différente ont été comparés en ce qui concerne la qualité de la révision (produit), la détection d’erreurs et la durée du processus de révision (processus). Une analyse de la variance (ANOVA) a révélé que la relecture unilingue n’est pas significativement moins efficace, en termes de qualité et de potentiel de détection d’erreurs, qu’une relecture bilingue, mais qu’elle ne prend pas non plus significativement moins de temps. En revanche, si la relecture unilingue est significativement moins efficace que les relectures doubles, elle prend aussi significativement moins de temps.
Anthropologie des lectures féministes de la traduction
Authors: Wilhelm Jane 
Published: September 2016

Cet article se propose d’examiner différentes théories de la lecture, de l’écriture et de la traduction dans le cadre d’une anthropologie interdisciplinaire de la traduction et à partir d’une réflexion féministe se situant aussi dans une perspective herméneutique. Si le concept de « genre » est une catégorie d’analyse utilisée pour désigner les rapports sociaux entre les sexes, c’est également unegrille de lecturede constructions sociales signifiant des rapports de pouvoir. En effet, l’évolution actuelle des sociétés remet en question les acquis du mouvement féministe depuis les années 1970, et la traduction, en mettant au jour des enjeux de pouvoir, peut apporter de nouveaux éléments dans les débats autour de la question du rapport au pouvoir et celle de la violence de la tradition patriarcale. Notre examen de la symbolique de la hiérarchisation valorisant le masculin se réfère notamment aux travaux de Françoise Héritier sur la pensée de la différence sexuée dans les systèmes de représentation. Nous examinerons, à la suite de Lori Chamberlain, l’isotopie métaphorique de la sexualité et du mariage en traduction et le modèle masculin de George Steiner. Nous évoquerons aussi, en souscrivant à l’idée d’un « inconscient théologique » avancée par Jean-René Ladmiral, l’horizon d’un inconscient amoureux qui lui serait lié et qui nous paraît être à l’oeuvre dans toute la pensée sur la traduction et la réflexion traductologique. D’autres lectures de la traduction dans leur dimension amoureuse ou érotique seront également abordées, en particulier celles de Valery Larbaud et de Serge Gavronsky s’articulant autour de l’inconscient freudien. Nous opposerons à l’isotopie métaphorique de la sexualité en traduction et au modèle de Steiner différentes lectures féministes illustrant la liberté de s’insurger contre les stéréotypes et l’inégalité entre les sexes, tout en ouvrant la réflexion sur la question de l’autorité. Les questions de genre, de sexualité et d’autorité en traduction font apparaître des enjeux proprement politiques, et il conviendra en conclusion d’insister sur le pluralisme de l’autorité.
Liquidité du marché des actions et rendements des fonds mutuels en temps de crise : évidence canadienne
Authors: Beaulieu Marie-Claude , Carrier Simon , Guimond Jean-François 
Published: September 2016

Cet article porte sur la relation entre les rendements des fonds mutuels canadiens et la liquidité du marché des actions. Nous cherchons spécifiquement à documenter comment cette relation a évolué au cours de la période entourant la crise de liquidité qui a secoué le monde financier en 2008. Ces travaux sont importants puisque d’une part, les fonds mutuels sont des véhicules d’investissements très présents dans l’économie et d’autre part, la liquidité des marchés financiers est un catalyseur du risque systémique. Nos résultats montrent que la prime d’illiquidité traditionnellement observée au sein des fonds mutuels avant la crise – dont dans cette étude – a donné lieu à une prime d’illiquidité au plus fort de la crise et a modifié l’évaluation de ces fonds par la suite.

Abstract
The response of hexagonal (4H) silicon carbide (SiC) power metal–oxide–semiconductor field effect transistors (MOSFETs) to gamma-ray irradiation was investigated under elevated temperature and humid conditions. The shift in drain current–gate voltage (I
D–V
G) curves towards negative voltages and the leakage of I
D with a current hump due to elevated temperature irradiation were suppressed under high humidity conditions relative to dry conditions. This result can be explained in terms of the reduction in trapped oxide charge and oxide–SiC interface traps generated by irradiation due to the humid conditions. In addition, during irradiation at elevated temperature in humid conditions, electron traps at the oxide–SiC interface obviously decrease at doses above 100 kGy.
Improvement in luminance efficiency of organic light emitting diodes by suppression of secondary electron bombardment of substrate during sputter deposition of top electrode films

Published: September 2016

Abstract
In this study, we investigated the degradation mechanisms of the luminance performance of organic light-emitting diodes (OLEDs) when their top electrode films were deposited by sputter deposition process. During the sputter deposition of the top electrode films, the suppression of the incidence of high-energy electrons on the substrate was attempted using various methods. As a result, we found that during electrode deposition, the incidence of the high-energy secondary electrons, which were emitted from the target surface, on the substrate was the main cause of the significant degradation of the luminance performance. It was also found that the application of a magnetic field by setting permanent magnets near the substrate holder and the insertion of a shield plate near the target cathode were effective in suppressing the incidence of secondary electrons on the substrate.
Digital Accessible Knowledge and well-inventoried sites for birds in Mexico: baseline sites for measuring faunistic change
Authors: Peterson A. Townsend , Navarro-Sigüenza Adolfo G. , Martínez-Meyer Enrique 
Published: September 2016

BackgroundFaunal change is a basic and fundamental element in ecology, biogeography, and conservation biology, yet vanishingly few detailed studies have documented such changes rigorously over decadal time scales. This study responds to that gap in knowledge, providing a detailed analysis of Digital Accessible Knowledge of the birds of Mexico, designed to marshal DAK to identify sites that were sampled and inventoried rigorously prior to the beginning of major global climate change (1980).MethodsWe accumulated DAK records for Mexican birds from all relevant online biodiversity data portals. After extensive cleaning steps, we calculated completeness indices for each 0.05° pixel across the country; we also detected ‘hotspots’ of sampling, and calculated completeness indices for these broader areas as well. Sites were designated as well-sampled if they had completeness indices above 80% and >200 associated DAK records.ResultsWe identified 100 individual pixels and 20 broader ‘hotspots’ of sampling that were demonstrably well-inventoried prior to 1980. These sites are catalogued and documented to promote and enable resurvey efforts that can document events of avifaunal change (and non-change) across the country on decadal time scales.ConclusionsDevelopment of repeated surveys for many sites across Mexico, and particularly for sites for which historical surveys document their avifaunas prior to major climate change processes, would pay rich rewards in information about distributional dynamics of Mexican birds.

BackgroundLeft ventricular hypertrophy (LVH) is a marker of pediatric hypertension and predicts development of cardiovascular events. Electrocardiography (ECG) screening is used in pediatrics to detect LVH thanks to major accessibility, reproducibility and easy to use compared to transthoracic echocardiography (TTE), that remains the standard technique. Several diseases were previously investigated, but no data exists regarding our study population. The aim of our study was to evaluate the relationship between electrocardiographic and echocardiographic criteria of LVH in normotensive African children.MethodsWe studied 313 children (mean age 7,8 ± 3 yo), in north-Madagascar. They underwent ECG and TTE. Sokolow-Lyon index was calculated to identify ECG-LVH (>35 mm). Left ventricle mass (LVM) with TTE was calculated and indexed by height2.7(LVMI2.7) and weight (LVMIw). We report the prevalence of TTE-LVH using three methods: (1) calculating percentiles age- and sex- specific with values >95th percentile identifying LVH; (2) LVMI2.7>51 g/m2.7; (3) LVMIw>3.4 g/weight.Results40 (13%) children showed LVMI values >95th percentile, 24 children (8%) an LVMI2.7>51 g/m2.7while 19 children (6%) an LVMIw>3.4 g/kg. LVH-ECG by Sokolow-Lyon index was present in five, three and three children respectively, with poor values of sensitivity (ranging from 13 to 16%), positive predictive value (from 11 to 18%) and high values of specificity (up to 92%). The effects of anthropometrics parameters on Sokolow-Lyon were analyzed and showed poor correlation.ConclusionECG is a poor screening test for detecting LVH in children. In clinical practice, TTE remains the only tool to be used to exclude LVH.
Generation of He+ and O+ EMIC waves by the bunch distribution of O+ ions associated with fast magnetosonic shocks in the magnetosphere
Authors: Lee K. H. , Lee L. C. 
Published: September 2016

AbstractElectromagnetic ion cyclotron (EMIC) waves are often observed in the magnetosphere with frequency usually in the H+ and He+ cyclotron bands and sometimes in the O+ band. The temperature anisotropy, caused by injection of energetic ions or by compression of magnetosphere, can efficiently generate H+ EMIC waves, but not as efficient for He+ or O+ EMIC waves. Here we propose a new generation mechanism for He+ and O+ EMIC waves associated with weak fast magnetosonic shocks, which are observed in the magnetosphere. These shocks can be associated with either dynamic pressure enhancement or shocks in the solar wind and can lead to the formation of a “bunch” distribution in the perpendicular velocity plane of O+ ions. The O+ bunch distribution can excite strong He+ EMIC waves and weak O+ and H+ waves. The dominant He+ EMIC waves are strong in quasi‐perpendicular propagation and show harmonics in frequency spectrum of Fourier analysis. The proposed mechanism can explain the generation and some observed properties of He+ and O+ EMIC waves in the magnetosphere.
