ABSTRACT
We report our very early optical observations of GRB 110530A and investigate its jet properties together with its X-ray afterglow data. A peculiar broad onset bump followed by a plateau is observed in its early R band afterglow light curve. The optical data in the other bands and the X-ray data are well consistent with the temporal feature of the R band light curve. Our joint spectral fits of the optical and X-ray data show that they are in the same regime, with a photon index of ∼1.70. The optical and X-ray afterglow light curves are well fitted with the standard external shock model by considering a delayed energy injection component. Based on our modeling results, we find that the radiative efficiency of the gamma-ray burst jet is

and the magnetization parameter of the afterglow jet is

with a derived extremely low

(the ratio of shock energy to the magnetic field) of

. These results indicate that the jet may be matter dominated. A discussion on delayed energy injection from the accretion of the late fall-back material of its pre-supernova star is also presented.
QUASARS PROBING QUASARS. VIII. THE PHYSICAL PROPERTIES OF THE COOL CIRCUMGALACTIC MEDIUM SURROUNDING z ∼ 2–3 MASSIVE GALAXIES HOSTING QUASARS

ABSTRACT
We characterize the physical properties of the cool T ∼ 104 K circumgalactic medium (CGM) surrounding z ∼ 2–3 quasar host galaxies, which are predicted to evolve into present-day massive ellipticals. Using a statistical sample of 14 quasar pairs with projected separation <300 kpc and spectra of high dispersion and high signal-to-noise ratio, we find extreme kinematics with low metal ion lines typically spanning ≈500 km s−1, exceeding any previously studied galactic population. The CGM is significantly enriched, even beyond the virial radius, with a median metallicity [M/H] ≈ −0.6. The α/Fe abundance ratio is enhanced, suggesting that halo gas is primarily enriched by core-collapse supernovae. The projected cool gas mass within the virial radius is estimated to be 1.9 × 1011
M
⊙ (R
⊥/160 kpc)2, accounting for ≈1/3 of the baryonic budget of the galaxy halo. The ionization state of CGM gas increases with projected distance from the foreground quasars, contrary to expectation if the quasar dominates the ionizing radiation flux. However, we also found peculiarities not exhibited in the CGM of other galaxy populations. In one absorption system, we may be detecting unresolved fluorescent Lyα emission, and another system shows strong N v lines. Taken together, these anomalies suggest that transverse sightlines are—at least in some cases—possibly illuminated. We also discovered a peculiar case where detection of the C ii fine-structure line implies an electron density >100 cm−3 and sub-parsec-scale gas clumps.
RADIO TRANSIENTS FROM ACCRETION-INDUCED COLLAPSE OF WHITE DWARFS
Authors: Moriya Takashi J. 
Published: October 2016

ABSTRACT
We investigate observational properties of accretion-induced collapse (AIC) of white dwarfs (WDs) in radio frequencies. If AIC is triggered by accretion from a companion star, a dense circumstellar medium can be formed around the progenitor system. Then, the ejecta from AIC collide with the dense circumstellar medium, creating a strong shock. The strong shock can produce synchrotron emission that can be observed in radio frequencies. Even if AIC occurs as a result of WD mergers, we argue that AIC may cause fast radio bursts (FRBs) if a certain condition is satisfied. If AIC forms neutron stars (NSs) that are so massive that rotation is required to support themselves (i.e., supramassive NSs), the supramassive NSs may immediately lose their rotational energy by the r-mode instability and collapse to black holes. If the collapsing supramassive NSs are strongly magnetized, they may emit FRBs, as previously proposed. The AIC radio transients from single-degenerate systems may be detected in future radio transient surveys like the Very Large Array Sky Survey or the Square Kilometer Array transient survey. Because AIC has been proposed as a source of gravitational waves (GWs), GWs from AIC may be accompanied by radio-bright transients that can be used to confirm the AIC origin of observed GWs.
Définir et élaborer l’étiquette
Authors: Hassler Éric 
Published: October 2016

Lorsque le duc Léopold de Lorraine (1679-1729) recouvre ses duchés en 1698, il entreprend de ressusciter l’ancienne cour de Nancy. Confronté à de rapides querelles de préséance, le duc se voit dans l’obligation d’élaborer une réglementation du rang qu’il va nommer « étiquette » dans les deux écrits autographes qui nous sont conservés. Ces deux documents condensent le résultat clairement verbalisé des réflexions ducales sur la manière dont le prince définit l’étiquette et conçoit son rôle, à la fois dans la régulation des rapports sociaux entre les courtisans et dans la mise en valeur de la personne souveraine. Leur étude permet d’abord de mettre en lumière les dimensions linguistique, sémantique et historique du terme d’étiquette utilisé, puis abandonné par Léopold au profit de celui de cérémonial, mais aussi d’analyser les influences française et germanique qui ont conditionné cet emploi. Ces deux notes mettent aussi en lumière la vision avant tout utilitaire que le duc avait de l’étiquette, perçue comme un outil de mise en ordre d’une cour désordonnée plutôt que comme un cadre symbolique pour la glorification de la personne ducale. Enfin, elles offrent la possibilité d’observer les processus d’élaboration de l’étiquette et du cérémonial, spécialement dans un entre-deux culturel.
Differential Role of Hematopoietic and Nonhematopoietic Cell Types in the Regulation of NK Cell Tolerance and Responsiveness
Authors: Tovbis Shifrin Nataliya , Kissiov Djem U. , Ardolino Michele , Joncker Nathalie T. , Raulet David H. 
Published: October 2016

Abstract
Many NK cells express inhibitory receptors that bind self-MHC class I (MHC I) molecules and prevent killing of self-cells, while enabling killing of MHC I–deficient cells. But tolerance also occurs for NK cells that lack inhibitory receptors for self-MHC I, and for all NK cells in MHC I–deficient animals. In both cases, NK cells are unresponsive to MHC I–deficient cells and hyporesponsive when stimulated through activating receptors, suggesting that hyporesponsiveness is responsible for self-tolerance. We generated irradiation chimeras, or carried out adoptive transfers, with wild-type (WT) and/or MHC I–deficient hematopoietic cells in WT or MHC I–deficient C57BL/6 host mice. Unexpectedly, in WT hosts, donor MHC I–deficient hematopoietic cells failed to induce hyporesponsiveness to activating receptor stimulation, but did induce tolerance to MHC I–deficient grafts. Therefore, these two properties of NK cells are separable. Both tolerance and hyporesponsiveness occurred when the host was MHC I deficient. Interestingly, infections of mice or exposure to inflammatory cytokines reversed the tolerance of NK cells that was induced by MHC I–deficient hematopoietic cells, but not the tolerance induced by MHC I–deficient nonhematopoietic cells. These data have implications for successful bone marrow transplantation, and suggest that tolerance induced by hematopoietic cells versus nonhematopoietic cells may be imposed by distinct mechanisms.

Abstract
Chromatin remodeling seems to regulate the patterns of proinflammatory genes. Our aim was to provide new insights into the epigenetic mechanisms that control transcriptional activation of early- and late-response genes in initiation and development of severe acute pancreatitis as a model of acute inflammation. Chromatin changes were studied by chromatin immunoprecipitation analysis, nucleosome positioning, and determination of histone modifications in promoters of proinflammatory genes in vivo in the course of taurocholate-induced necrotizing pancreatitis in rats and in vitro in rat pancreatic AR42J acinar cells stimulated with taurocholate or TNF-α. Here we show that the upregulation of early and late inflammatory genes rely on histone acetylation associated with recruitment of histone acetyltransferase CBP. Chromatin remodeling of early genes during the inflammatory response in vivo is characterized by a rapid and transient increase in H3K14ac, H3K27ac, and H4K5ac as well as by recruitment of chromatin-remodeling complex containing BRG-1. Chromatin remodeling in late genes is characterized by a late and marked increase in histone methylation, particularly in H3K4. JNK and p38 MAPK drive the recruitment of transcription factors and the subsequent upregulation of early and late inflammatory genes, which is associated with nuclear translocation of the early gene Egr-1. In conclusion, specific and strictly ordered epigenetic markers such as histone acetylation and methylation, as well as recruitment of BRG-1–containing remodeling complex are associated with the upregulation of both early and late proinflammatory genes in acute pancreatitis. Our findings highlight the importance of epigenetic regulatory mechanisms in the control of the inflammatory cascade.

Abstract
Flavivirus nonstructural protein 1 (NS1) is a unique secreted nonstructural glycoprotein. Although it is absent from the flavivirus virion, intracellular and extracellular forms of NS1 have essential roles in viral replication and the pathogenesis of infection. The fate of NS1 in insect cells has been more controversial, with some reports suggesting it is exclusively cell associated. In this study, we confirm NS1 secretion from cells of insect origin and characterize its physical, biochemical, and functional properties in the context of dengue virus (DENV) infection. Unlike mammalian cell–derived NS1, which displays both high mannose and complex type N-linked glycans, soluble NS1 secreted from DENV-infected insect cells contains only high mannose glycans. Insect cell–derived secreted NS1 also has different physical properties, including smaller and more heterogeneous sizes and the formation of less stable NS1 hexamers. Both mammalian and insect cell–derived NS1 bind to complement proteins C1s, C4, and C4-binding protein, as well as to a novel partner, mannose-binding lectin. Binding of NS1 to MBL protects DENV against mannose-binding lectin–mediated neutralization by the lectin pathway of complement activation. As we detected secreted NS1 and DENV together in the saliva of infected Aedes aegypti mosquitoes, these findings suggest a mechanism of viral immune evasion at the very earliest phase of infection.
Validating an integrated decision-support framework for road transportation in Gauteng, South Africa
Authors: Backeberg Greorg H. 
Published: October 2016

The South African government has committed itself to creating “a better life for all”. Furthermore, government performance became important for the South African government with the introduction of the Public Finance Management Act. Backeberg (2005) uses systems thinking to propose a holistic transportation performance quantification framework to achieve the above. The purpose of this research is to validate the above framework by demonstrating its practicality and usefulness. This is done by populating the framework with representative transportation statistics from various sources. The study demonstrates how improvements could be prioritised if adequate information were to be available.

Published: October 2016

Background Globally, breast cancer (BC) has become the leading cause of mortality in women. Awareness and early detection can curb the growing burden of BC and are the first step in the battle against BC. The aim of this qualitative study was to explore the awareness and perceived barriers concerning the early detection of BC. Methods A total of 20 focus group discussions (FGDs) were conducted during May 2013–March 2014. Pre-existing themes were used to conduct FGDs; each FGD group consisted of an average of ~10 women (aged ≥18–70 years) who came to participate in a BC awareness workshop. All FGDs were audio taped and transcribed verbatim. The transcripts were inductively analyzed using ATLAS.ti. Based on emerged codes and categories, thematic analysis was done, and theory was developed using the grounded theory approach. Results Data were analyzed in three major themes: i) knowledge and perception about BC; ii) barriers faced by women in the early presentation of BC; and iii) healthcare-seeking behavior. The findings revealed that shyness, fear, and posteriority were the major behavioral barriers in the early presentation of BC. Erroneously, pain was considered as an initial symptom of BC by most women. Financial constraint was also mentioned as a cause for delay in accessing treatment. Social stigma that breast problems reflect bad character of women also contributed in hiding BC symptoms. Conclusions Lack of BC awareness was prevalent, especially in low socioeconomic class. Women's ambivalence in prioritizing their own health and social and behavioral hurdles should be addressed by BC awareness campaigns appropriately suited for various levels of social class.
Gendering the European Digital Agenda: The Challenge of Gender Mainstreaming Twenty Years after the Beijing World Conference on Women
Authors: Padovani Claudia 
Published: October 2016

AbstractThe goals set out in the 1995 Platform for Action of the Beijing World Conference on Women—to achieve gender equality in and through the media—interrogate today's digital policies: To what extent have internationally agreed-upon norms of gender equality and gender mainstreaming been recognized and implemented? To what extent has the knowledge produced by feminist scholarship informed media policy developments? What kind of new knowledge, and analytical frameworks, may contribute to unmask gender-unequal power relations in contemporary media environments? The article addresses these questions with a focus on European discourses and institutional practices for the Digital Agenda.
Correlation of Prenatal Diagnosis and Pathology Findings Following Dilation and Evacuation for Fetal Anomalies
Authors: Boecking Carolin A. , Drey Eleanor A. , Kerns Jennifer L. , Finkbeiner Walter E. 
Published: October 2016

Context.—Despite increased use of dilation and evacuation in the setting of fetuses with developmental anomalies, the pathology examination of fragmented specimens obtained by this technique has been understudied.
Objectives.—To correlate pathologic findings in second-trimester fetal dilation and evacuation specimens with prenatal diagnoses established through ultrasound and/or chromosome studies to determine the value of pathology examination for supplementing or correcting clinical diagnoses.
Design.—In this retrospective study, clinical and pathology findings were correlated in 448 dilation and evacuation specimens performed for second-trimester termination of pregnancy for fetal anomalies discovered on ultrasound examination (278 cases) or chromosome analysis (170 cases).
Results.—In 109 of the 170 cases with chromosomal abnormalities (64%), pathologists identified at least 1 congenital defect associated with the respective karyotype. In 278 cases with ultrasound-detected anomalies, pathologists confirmed the major congenital defect in 116 fetal specimens (42%). Evaluating for congenital central nervous system and body wall/diaphragm pathologic findings proved challenging owing to tissue disruption. However, taking all categories into account, pathology studies corrected ultrasound diagnoses in 152 of 413 cases (37%) and yielded additional diagnostic findings in 137 cases (33%).
Conclusions.—In a substantial number of cases, examination of fragmented fetuses corrected or refined prenatal diagnoses, demonstrating a role for detailed pathology examination of dilation and evacuation specimens in quality control of prenatal imaging studies and for potentially aiding subsequent genetic counseling.

Authors: Borczuk Alain C. 
Published: October 2016

Context.—The use of frozen section in thoracic pathology includes assessment of peripheral lung lesions with lepidic pattern, with greater emphasis on evaluating lung-sparing resections and margin assessment.Objective.—To review pitfalls of frozen section in thoracic pathology; in this setting, reduction of false-positive and false-negative diagnosis in lesion identification and margin assessment is critical.Data Sources.—PubMed search of frozen section lung pathology yielded specific references related to the use of frozen section in the identification of lepidic lesions and the clinical recommendation for margin distance.Conclusions.—Frozen section diagnosis is overall accurate in assessment of lepidic lesions. Pitfalls include rare benign mimickers and more common reactive lesions. Standard approaches to gross assessment and margin measurement require further research with increasing use of lung-sparing resections.
Théâtre : le lieu où l’on entend
Authors: Larrue Jean-Marc , Mervant-Roux Marie-Madeleine 
Published: October 2016

Les deux auteurs proposent, dans cet article, une genèse des études sonores en théâtre dont l’émergence est toute récente, puisqu’elles n’ont pas dix ans. Ils précisent les défis auxquels elles ont été et sont confrontées, les objets qu’elles examinent. Après avoir défini l’auralité théâtrale et avancé certaines hypothèses sur l’« oubli » du son au sein des études théâtrales, les auteurs montrent comment la transformation des représentations (mentales et scientifiques) de l’ouïe et de l’espace aural, principalement depuis l’avènement des technologies de reproduction du son à la fin du XIXesiècle, s’est répercutée sur les scènes, renouvelant radicalement les pratiques scéniques des XXeet XXIesiècles.
Dispositifs sonores et écoute performative : le cas de l’Autoteatro par la compagnie Rotozaza
Authors: Kapelusz Anyssa 
Published: October 2016

Avec le cycle Autoteatro, la compagnie britannique Rotozaza crée, depuis 2007, des protocoles participatifs qui s’appuient sur des bandes-son préenregistrées. Celles-ci permettent de cadrer et d’organiser la rencontre et les interactions ludiques entre plusieurs spectateurs. Destinés à être performés, ces dispositifs sonores génèrent une expérience spécifique chez le participant, impliquant l’émergence d’une « écoute performative » qui se construit dans une tension vers l’acte à incorporer et à effectuer. Plus encore, ces dispositifs constituent une interrogation en acte de la théâtralité, puisque s’y opère un bouleversement des fonctions actoriales et spectatorielles. Ils offrent de réfléchir au développement de pratiques spectatrices singulières et diversifiées.
Re : Walden, jouer Écho contre Narcisse : l’art poétique sonore de Jean-François Peyret
Authors: Ballay Jean-François 
Published: October 2016

En prenant pour point de départ un classique de la littérature américaine, Walden de Henry David Thoreau, Jean-François Peyret a mis en place un dispositif scénotechnique qui confronte acteurs, musique augmentée, création sonore, traitement d’images, voix de synthèse et avatars pour créer une anamorphose poétique, sonore et visuelle. Le spectacle, intitulé Re : Walden, nous invite à considérer non pas le double spéculaire, dont la figure mythique est celle de Narcisse, mais le double comme Écho, c’est-à-dire comme répétition à l’infini et accessoirement comme trouble de la mémoire, dans un monde qu’il nous faut sans cesse apprendre à habiter, sous peine de disparaître…
Radio Cargo Cult Liturgy : essai de transposition du théâtre radiophonique dans le visible
Authors: Cousins Rick , Léopold Janine 
Published: October 2016

Les reprises sur scène de radio-théâtres de ce qu’on appelle l’âge d’or de la radio – qui correspond aux années 1930 et 1940 – prennent souvent des allures parodiques qu’on peut attribuer aux maladresses involontaires de ce type de productions radiophoniques. Cela soulève une question de fond : existe-t-il des éléments caractéristiques de cette esthétique des radio-théâtres qui soient transposables sur scène, dans des productions fondées sur la présence et le visuel? Pour répondre à cette question, l’auteur et une équipe de collègues artistes ont effectué une reprise d’un radio-théâtre phare de cette époque, appuyant l’auralité du radio-théâtre par des mouvements et des gestes scéniques. Il en résulte la création d’un nouveau texte qui fait la satire de cette vénération nostalgique de ce soi-disant âge d’or de la radio.
Réflexion sur les distances : mise en scène des voix
Authors: Finer Ella , Léopold Janine 
Published: October 2016

Cet article porte sur la dynamique de la voix dans ses dimensions physiques et temporelles. Allant des recherches sur le son menées au XVIIIe siècle à la théorisation de Mladen Dolar sur la voix désincarnée, en passant par les expériences de certains dramaturges sur l’écoute et la réécoute du son de la représentation, l’auteure examine certaines pratiques de production sonore, dont 1) l’utilisation de voix live et de voix enregistrées; 2) le ventriloquisme et l’acousmatisation. C’est à partir de ces pratiques qu’elle analyse la performativité et la matérialité de la voix. L’article repose sur l’hypothèse suivante : la voix dont la source corporelle ne serait ni visible ni perceptible ne contribue pas à la mise en scène mais en devient un élément matériel. Il se termine par une analyse du personnage de la Voix dans Eh Joe que Samuel Beckett a écrit pour la télévision en 1965.
