STAR FORMATION AND SUPERCLUSTER ENVIRONMENT OF 107 NEARBY GALAXY CLUSTERS
Authors: Cohen Seth A. , Hickox Ryan C. , Wegner Gary A. , Einasto Maret , Vennik Jaan 
Published: January 2017

ABSTRACT
We analyze the relationship between star formation (SF), substructure, and supercluster environment in a sample of 107 nearby galaxy clusters using data from the Sloan Digital Sky Survey. Previous works have investigated the relationships between SF and cluster substructure, and cluster substructure and supercluster environment, but definitive conclusions relating all three of these variables has remained elusive. We find an inverse relationship between cluster SF fraction (f
SF) and supercluster environment density, calculated using the Galaxy luminosity density field at a smoothing length of 8 h
−1 Mpc (D8). The slope of f
SF versus D8 is −0.008 ± 0.002. The f
SF of clusters located in low-density large-scale environments, 0.244 ± 0.011, is higher than for clusters located in high-density supercluster cores, 0.202 ± 0.014. We also divide superclusters, according to their morphology, into filament- and spider-type systems. The inverse relationship between cluster f
SF and large-scale density is dominated by filament- rather than spider-type superclusters. In high-density cores of superclusters, we find a higher f
SF in spider-type superclusters, 0.229 ± 0.016, than in filament-type superclusters, 0.166 ± 0.019. Using principal component analysis, we confirm these results and the direct correlation between cluster substructure and SF. These results indicate that cluster SF is affected by both the dynamical age of the cluster (younger systems exhibit higher amounts of SF); the large-scale density of the supercluster environment (high-density core regions exhibit lower amounts of SF); and supercluster morphology (spider-type superclusters exhibit higher amounts of SF at high densities).

Abstract
We study a model of rapidly cooling shocked stellar winds in young massive clusters and estimate the circumstances under which secondary star formation, out of the reinserted winds from a first stellar generation (1G), is possible. We have used two implementations of the model: a highly idealized, computationally inexpensive, spherically symmetric semi-analytic model, and a complex, three-dimensional radiation-hydrodynamic, simulation; they are in a good mutual agreement. The results confirm our previous findings that, in a cluster with 1G mass 107
M
⊙ and half-mass–radius 2.38 pc, the shocked stellar winds become thermally unstable, collapse into dense gaseous structures that partially accumulate inside the cluster, self-shield against ionizing stellar radiation, and form the second generation (2G) of stars. We have used the semi-analytic model to explore a subset of the parameter space covering a wide range of the observationally poorly constrained parameters: the heating efficiency, η
he, and the mass loading, η
ml. The results show that the fraction of the 1G stellar winds accumulating inside the cluster can be larger than 50% if η
he ≲ 10%, which is suggested by the observations. Furthermore, for low η
he, the model provides a self-consistent mechanism predicting 2G stars forming only in the central zones of the cluster. Finally, we have calculated the accumulated warm gas emission in the H30α recombination line, analyzed its velocity profile, and estimated its intensity for super star clusters in interacting galaxies NGC4038/9 (Antennae) showing that the warm gas should be detectable with ALMA.
COMPARING CORONAL AND HELIOSPHERIC MAGNETIC FIELDS OVER SEVERAL SOLAR CYCLES
Authors: Koskela J. S. , Virtanen I. I. , Mursula K. 
Published: January 2017

ABSTRACT
Here we use the PFSS model and photospheric data from Wilcox Solar Observatory, SOHO/MDI, SDO/HMI, and SOLIS to compare the coronal field with heliospheric magnetic field measured at 1 au, compiled in the NASA/NSSDC OMNI 2 data set. We calculate their mutual polarity match and the power of the radial decay, p, of the radial field using different source surface distances and different number of harmonic multipoles. We find the average polarity match of 82% for the declining phase, 78%–79% for maxima, 76%–78% for the ascending phase, and 74%–76% for minima. On an average, the source surface of 3.25 R

S
gives the best polarity match. We also find strong evidence for solar cycle variation of the optimal source surface distance, with highest values (3.3 R

S
) during solar minima and lowest values (2.6 R

S
–2.7 R

S
) during the other three solar cycle phases. Raising the number of harmonic terms beyond 2 rarely improves the polarity match, showing that the structure of the HMF at 1 au is most of the time rather simple. All four data sets yield fairly similar polarity matches. Thus, polarity comparison is not affected by photospheric field scaling, unlike comparisons of the field intensity.
An Open Catalog for Supernova Data

Published: January 2017

Abstract
We present the Open Supernova Catalog, an online collection of observations and metadata for presently 36,000+ supernovae and related candidates. The catalog is freely available on the web (https://sne.space), with its main interface having been designed to be a user-friendly, rapidly searchable table accessible on desktop and mobile devices. In addition to the primary catalog table containing supernova metadata, an individual page is generated for each supernova, which displays its available metadata, light curves, and spectra spanning X-ray to radio frequencies. The data presented in the catalog is automatically rebuilt on a daily basis and is constructed by parsing several dozen sources, including the data presented in the supernova literature and from secondary sources such as other web-based catalogs. Individual supernova data is stored in the hierarchical, human- and machine-readable JSON format, with the entirety of each supernova’s data being contained within a single JSON file bearing its name. The setup we present here, which is based on open-source software maintained via git repositories hosted on github, enables anyone to download the entirety of the supernova data set to their home computer in minutes, and to make contributions of their own data back to the catalog via git. As the supernova data set continues to grow, especially in the upcoming era of all-sky synoptic telescopes, which will increase the total number of events by orders of magnitude, we hope that the catalog we have designed will be a valuable tool for the community to analyze both historical and contemporary supernovae.

ABSTRACT
We conduct a multiwavelength continuum variability study of the Seyfert 1 galaxy NGC 5548 to investigate the temperature structure of its accretion disk. The 19 overlapping continuum light curves (

) combine simultaneous Hubble Space Telescope, Swift, and ground-based observations over a 180 day period from 2014 January to July. Light-curve variability is interpreted as the reverberation response of the accretion disk to irradiation by a central time-varying point source. Our model yields the disk inclination

We also infer the driving light curve and find that it correlates poorly with both the hard and soft X-ray light curves, suggesting that the X-rays alone may not drive the ultraviolet and optical variability over the observing period. We also decompose the light curves into bright, faint, and mean accretion-disk spectra. These spectra lie below that expected for a standard blackbody accretion disk accreting at

Corps et voix : quel travail dans la classe de français du premier cycle du secondaire ?
Authors: Gagnon Roxane , Dolz Joaquim 
Published: January 2017

Les dimensions vocales et corporelles font l’objet de peu d’attention dans la classe de français du secondaire. Les auteurs font l’hypothèse que les enseignants méconnaissent ces objets et que, pour cette raison, ils ne voient pas leur pertinence dans l’apprentissage de l’oral et de l’oralité. La contribution entend cependant définir les concepts de voix et de corps et examine leur traitement dans les programmes officiels pour la Suisse romande, ainsi que dans plusieurs ouvrages d’enseignement en usage dans les classes.
Des humanités aux sciences de la culture : actualité de la sémiostylistique
Authors: Kurts-Wöste Lia 
Published: January 2017

La sémiostylistique occupe une place importante aujourd’hui, dans ce moment historique de transition entre les sciences humaines et les sciences de la culture. Redéfinie à partir des années 1980 comme herméneutique matérielle des textes littéraires, elle reste, d’une part, le seul lieu institutionnel où se pratique encore la jonction entre littérature et sciences du langage ; elle lègue, d’autre part, aux sciences de la culture la question esthétique, qu’il s’agit de redéfinir au sein d’une sémiotique des cultures sous le nom d’ esthétique fondamentale ou théorie de la valeur . Loin de n’être qu’une discipline de concours de peu de portée, elle constitue ainsi un laboratoire épistémologique d’avenir pour penser une sémio-anthropologie d’inspiration culturaliste.
Nationalité et citoyenneté
Authors: Schnapper Dominique 
Published: January 2017

La confusion de la nationalité et de la citoyenneté a caractérisé l’histoire des démocraties modernes. Aujourd’hui, certains pensent une « nouvelle citoyenneté », qui serait fondée sur la construction européenne ou sur la participation économique et sociale. D’autres prônent la dissociation de la citoyenneté et de la nationalité. Les sociétés démocratiques peuvent-elles évacuer la dimension politique et l’ensemble des traditions et des institutions qui organisent la vie démocratique ? Nationalité et citoyenneté sont-elles dissociables ?
Post mortem
Authors: Finchelstein Gilles 
Published: January 2017

L’extension de la déchéance de nationalité aux binationaux condamnés pour crimes terroristes a enflammé le débat public. Proposée par le président de la République devant le Congrès, trois jours après les attentats du 13 novembre 2015, elle a été abandonnée le 30 mars 2016, devant l’impossibilité de faire aboutir la révision constitutionnelle. Au-delà de l’analyse des moments charnières de ce débat, des leçons peuvent en être utilement tirées sur l’autonomie du politique, les risques de l’urgence, la complexité de la formation de l’opinion et les dangers du débat sur la déchéance.
Nationalité et citoyenneté en situation coloniale et post-coloniale
Authors: Saada Emmanuelle 
Published: January 2017

Sous le Second Empire colonial français, les « sujets » ont été considérés comme des nationaux privés des droits du citoyen. Cette spécificité coloniale est un élément essentiel de l’histoire de la nationalité et de la citoyenneté dans le contexte français : non seulement elle révèle les tensions profondes entre tendances inclusives et exclusives, mais aussi, à travers le concept d’assimilation qu’elle a généré, elle a profondément influencé les définitions de l’appartenance nationale.
ARTICLE RETIRÉ : Prêter l’oreille à ceux qui n’ont pas les mots

« Prêter l’oreille à ceux qui n’ont pas les mots : pas si simple. Cela nous porte à écouter celui qui n’a pas la parole, celui d’avant la parole, celui que Jean-Bertrand Pontalis nommait “l’habitant du hors-langage”, l’ infans . » Ainsi se clôture cet article où l’auteur, à travers trois vignettes cliniques, montre la difficulté à entendre ce que veut dire l’enfant qui ne parle pas encore : un bébé en longs pleurs douloureux pour la mère, un enfant inquiet des séparations d’avec sa mère et une petite fille enfermée dans son monde bien à elle.

C comme « Chut », D comme droit de se taire, O comme omerta, P comme « Parle »… pour finir par Z comme Zoé la menteuse. Les auteures de cet abécédaire, centré sur la fonction de la parole dans les relations enfant-adulte, s’intéressent aux figures de l’enfant menteur et de l’enfant taiseux. Dire ou se taire, parler vrai ou mentir, ne pas réduire la parole à son énoncé, s’intéresser à sa fonction d’adresse à l’autre, permet d’appréhender la question de la vérité du sujet. L’adulte (parent, éducateur, assistant familial…) saura-t-il écouter l’enfant ? « Ne le privons pas du plaisir de se trouver en le pressant de questions. Ne le dépossédons pas de ce qu’il a inventé pour vivre en lui arrachant son masque. »

Humanités numériques responsables
Authors: Reber Bernard 
Published: January 2017

Les humanités numériques sont bien loin de se résumer aux seules sciences documentaires augmentées. Elles affectent les savoirs eux-mêmes. Cet article part donc des humanités dans leur origine historique pour comparer et lier de diverses manières les sciences qui lisent et celles qui comptent. Il aborde également les façons dont ces sciences se répondent, un des sens de responsabilité (responsiveness). Nous esquisserons cinq itinéraires de pensée au sein des humanités numériques, entre technologies de l’information et de communication et sciences humaines et sociales. Cela fera le lien entre les humanités numériques et la notion émergente, principalement en Europe, d’Innovation et de recherche responsables (IRR). Elle est différente des évaluations éthiques qui s’imposent déjà à toute recherche (Ethical compliance). Celles qui comportent des technologies d’information (TIC) ont détrôné par leur nombre celles qui préoccupaient la bioéthique. Nous verrons alors la richesse des conceptions de la responsabilité morale. Nous terminerons avec des problèmes liés à l’ontologie des humanités numériques, à celle de l’action, et à la décontextualisation qu’elles induisent.

Published: January 2017

Abstract
Background: The organoleptic evaluation is considered the gold standard between evaluation methods of halitosis, but its main drawback is the difficulty of reproducibility. Purpose: The aim of this study was to evaluate the reproducibility of an organoleptic evaluation method using three levels of scores (0 = no odor, 1 = moderate odor, and 2 = strong odor) to increase reliability between researchers and clinicians. Methods: The evaluation was blindly conducted by two examiners previously calibrated by the Smell Identification Test and compliance in clinical trials. Statistical calculations were done with STATA ® software version 9.0. Results: The degree of agreement between examiners was 82.5%, with estimated Kappa (κ=0.69), with substantial agreement. Conclusion: The scale used in this study by organoleptic method was effective and reproducible but must be repeated and compared to other methods for better consistency of results.

Abstract
Aim: The study was undertaken to compare the filling quality of a 30 gauge cannula (NaviTip™, Ultradent Inc., South Jordan, UT, USA) used on a pressure syringe with a lentulospiral in primary molars. Materials and Methods: Thirty mandibular first and second primary molars in 28 healthy children of both sexes in the age group of 4-8 years were included in the study. All pulpectomy procedures were performed by one investigator. Before obturation, the subjects were randomly selected for the two obturation techniques. Effectiveness of the two obturation techniques was assessed by three independent evaluators using postoperative radiographs taken immediately after each obturation. Filling quality was determined by analyzing presence or absence of voids, extent of fill and apical seal. Results: The results of the obturation quality of the tested techniques were collected and statistically analyzed using chi-square test. There was a significant difference for the presence of voids between the two groups. NaviTip group showed the best results for the number of voids (mesial χ2 = 3.567, P = 0.0497) (distal χ2 = 5.058, P = 0.0269). The lentulospiral group showed more number of optimal fillings. When results were compared in terms of apical seal, NaviTip showed better apical seal but statistically no difference (P >.05). Conclusion: Lentulospiral produced the best results in terms of length of obturation, while NaviTip syringe was efficient enough in controlling voids and produced the best results for apical seal.

Abstract
Objectives: The aim of the study was to use clinical outcomes and digital radiographs to compare the effects of two types of sealant materials on the treatment of noncavitated occlusal caries lesions regarding their progression or arrest in teenage permanent molars. Methods: The sample consisted of 28 teeth from 20 patients aged 11-15 years with random distribution to receive either a resin-based sealant (Fluroshield ®, Dentsply, Philadelphia, PA, USA; Gres group) or a glass-ionomer sealant (RIVA Protect ®, SDI, São Paulo, Brazil; Ggis group). Caries progression was monitored by clinical evaluation and radiographic examination. Clinical outcomes were analyzed using the Mann-Whitney and Fisher′s exact test, and radiographic data were analyzed by Student′s t-test for paired data (P ≤ 0.05). Results: There were no significant differences between the clinical outcomes of both groups regarding the sealant retention, thermal sensitivity, and development of new caries lesions adjacent to the sealed surface. There was an increase in the radiographic density coefficient (carious dentin density/sound dentin density) at the end of the study for the Gres group (P = 0.003), but the coefficient for the Ggis group was similar for both time points (P = 0.49). Conclusions: Radiographic features showed an increase in the mineralization of the caries lesions when the teeth were sealed with a resin-based sealant; however, both techniques may be considered an adequate clinical approach for controlling the progression of the lesions.
Distribution of hypodontia and hyperdontia in concomitant hypo-hyperdontia patients: Critical appraisal of the published data
Authors: Chen Yong , Mallineni Sreekanth Kumar 
Published: January 2017

Abstract
Aim: Distribution of hypodontia and hyperdontia in the reported concomitant hypo-hyperdontia (CHH) patients. Materials and Methods: An extensive search of the reported literature from January 1966 to December 2015 was conducted using the “EmBase,” “Google Scholar,” “Medline,” and “PubMed” databases. The search words used were “agenesis,” “concomitant,” “hypodontia,” “hyperdontia,” “hypo-hyperdontia” “concomitant hypo-hyperdontia” and “supernumerary teeth” in different combinations. The citation lists from the included references were subsequently examined, and a hand search was performed in an attempt to find additional data. Detailed analyses of the incidence of hyperdontia and tooth type of hypodontia were evaluated to determine the occurrence of hypodontia and hyperdontia in this condition. Descriptive statistics were carried out using a Chi-square test to determine the occurrence of hypodontia and hyperdontia in CHH, the value of P < 0.05 was considered statistically significant. Results: Overall, 103 individuals were reported on CHH in published English literature. The average age of them was 11.29 years and frequently observed in males (P < 0.05). Overall 63% of teeth were missing in all the cases that were reported on CHH, whereas 37% of supernumerary teeth were documented (P < 0.05). Most of the cases involved are an anterior region of the both arches (57%). Second premolars are the most commonly missing teeth in both maxillary and mandibular arches, and maxillary mesiodens (50%) are frequent supernumeraries in CHH patients. Conclusion: Hypodontia is more common in CHH patients than hyperdontia. Second premolars are the commonly missing teeth while maxillary mesiodens are the frequently reported in CHH patients. Posterior CHH has not been reported.
