ABSTRACT
Supernovae (SNe) embedded in dense circumstellar material (CSM) may show prominent emission lines in their early-time spectra (≤10 days after the explosion), owing to recombination of the CSM ionized by the shock-breakout flash. From such spectra (“flash spectroscopy”), we can measure various physical properties of the CSM, as well as the mass-loss rate of the progenitor during the year prior to its explosion. Searching through the Palomar Transient Factory (PTF and iPTF) SN spectroscopy databases from 2009 through 2014, we found 12 SNe II showing flash-ionized (FI) signatures in their first spectra. All are younger than 10 days. These events constitute 14% of all 84 SNe in our sample having a spectrum within 10 days from explosion, and 18% of SNe II observed at ages <5 days, thereby setting lower limits on the fraction of FI events. We classified as “blue/featureless” (BF) those events having a first spectrum that is similar to that of a blackbody, without any emission or absorption signatures. It is possible that some BF events had FI signatures at an earlier phase than observed, or that they lack dense CSM around the progenitor. Within 2 days after explosion, 8 out of 11 SNe in our sample are either BF events or show FI signatures. Interestingly, we found that 19 out of 21 SNe brighter than an absolute magnitude M

R
= −18.2 belong to the FI or BF groups, and that all FI events peaked above M

R
= −17.6 mag, significantly brighter than average SNe II.
RE-INFLATED WARM JUPITERS AROUND RED GIANTS
Authors: Lopez Eric D. , Fortney Jonathan J. 
Published: February 2016

ABSTRACT
Since the discovery of the first transiting hot Jupiters, models have sought to explain the anomalously large radii of highly irradiated gas giants. We now know that the size of hot Jupiter radius anomalies scales strongly with a planet's level of irradiation and numerous models like tidal heating, ohmic dissipation, and thermal tides have since been developed to help explain these inflated radii. In general, however, these models can be grouped into two broad categories: models that directly inflate planetary radii by depositing a fraction of the incident irradiation into the interior and models that simply slow a planet's radiative cooling, allowing it to retain more heat from formation and thereby delay contraction. Here we present a new test to distinguish between these two classes of models. Gas giants orbiting at moderate orbital periods around post-main-sequence stars will experience enormous increases to their irradiation as their host stars move up the sub-giant and red-giant branches. If hot Jupiter inflation works by depositing irradiation into the planet's deep interiors then planetary radii should increase in response to the increased irradiation. This means that otherwise non-inflated gas giants at moderate orbital periods of >10 days can re-inflate as their host stars evolve. Here we explore the circumstances that can lead to the creation of these “re-inflated” gas giants and examine how the existence or absence of such planets can be used to place unique constraints on the physics of the hot Jupiter inflation mechanism. Finally, we explore the prospects for detecting this potentially important undiscovered population of planets.
ON THE FATE OF UNSTABLE CIRCUMBINARY PLANETS: TATOOINE’S CLOSE ENCOUNTERS WITH A DEATH STAR
Authors: Sutherland Adam P. , Fabrycky Daniel C. 
Published: February 2016

ABSTRACT
Circumbinary planets whose orbits become unstable may be ejected, accreted, or even captured by one of the stars. We quantify the relative rates of these channels, for a binary of secondary star’s mass fraction 0.1 with an orbit of 1 AU. The most common outcome is ejection, which happens ∼80% of the time. If binary systems form circumbinary planets readily and sloppily, this process may fill the Milky Way with free-floating planets. A significant fraction of the time, ∼20%, the unstable planet strikes the primary or secondary. We tracked whether a Jupiter-like planet would undergo tidal stripping events during close passages, and find that these events are rarely strong enough to capture the planet, although this may be observable via free-floating planets that are heated or spun-up by this process.
TILT ANGLE AND FOOTPOINT SEPARATION OF SMALL AND LARGE BIPOLAR SUNSPOT REGIONS OBSERVED WITH HMI
Authors: McClintock B. H. , Norton A. A. 
Published: February 2016

ABSTRACT
We investigate bipolar sunspot regions and how tilt angle and footpoint separation vary during emergence and decay. The Helioseismic and Magnetic Imager on board the Solar Dynamic Observatory collects data at a higher cadence than historical records and allows for a detailed analysis of regions over their lifetimes. We sample the umbral tilt angle, footpoint separation, and umbral area of 235 bipolar sunspot regions in Helioseismic and Magnetic Imager—Debrecen Data with an hourly cadence. We use the time when the umbral area peaks as time zero to distinguish between the emergence and decay periods of each region and we limit our analysis of tilt and separation behavior over time to within ±96 hr of time zero. Tilt angle evolution is distinctly different for regions with small (≈30 MSH), midsize (≈50 MSH), and large (≈110 MSH) maximum umbral areas, with 45 and 90 MSH being useful divisions for separating the groups. At the peak umbral area, we determine median tilt angles for small (7.°6), midsize (5.°9), and large (9.°3) regions. Within ±48 hr of the time of peak umbral area, large regions steadily increase in tilt angle, midsize regions are nearly constant, and small regions show evidence of negative tilt during emergence. A period of growth in footpoint separation occurs over a 72-hr period for all of the regions from roughly 40 to 70 Mm. The smallest bipoles (<9 MSH) are outliers in that they do not obey Joy's law and have a much smaller footpoint separation. We confirm the Muñoz-Jaramillo et al. results that the sunspots appear to be two distinct populations.
THICK ACCRETION DISK MODEL FOR ULTRALUMINOUS SUPERSOFT SOURCES
Authors: Gu Wei-Min , Sun Mou-Yuan , Lu You-Jun , Yuan Feng , Liu Ji-Feng 
Published: February 2016

ABSTRACT
We propose a geometrically thick, super-Eddington accretion disk model, where an optically thick wind is not necessary, to understand ultraluminous supersoft sources (ULSs). For high mass accretion rates

and not small inclination angles

, where

is the Eddington accretion rate, the hard photons from the hot inner region may be shaded by the geometrically thick inner disk, and therefore only the soft photons from the outer thin disk and the outer photosphere of the thick disk can reach the observer. Our model can naturally explain the approximate relation between the typical thermal radius and the thermal temperature,

. Moreover, the thick disk model can unify ULSs and normal ultraluminous X-ray sources, where the different observational characteristics are probably related to the inclination angle and the mass accretion rate. By comparing our model with the optically thick outflow model, we find that a lower mass accretion rate is required in our model.
Longitudinal Evaluation of Lipoprotein Variables in Systemic Lupus Erythematosus Reveals Adverse Changes with Disease Activity and Prednisone and More Favorable Profiles with Hydroxychloroquine Therapy

Published: February 2016

Objective.Systemic lupus erythematosus (SLE) is associated with accelerated atherosclerotic cardiovascular disease. Patients with SLE have adverse lipoprotein variables, but little is known about how these change with treatment and disease activity. The nuclear magnetic resonance LipoProfile test contains a glycoprotein signal-termed GlycA, an inflammatory marker, which has not been evaluated in SLE. We assessed patients longitudinally to determine how lipoproteins and GlycA change with active SLE.Methods.Sera from selected clinical visits of patients in the Hopkins Lupus Cohort were analyzed for lipoprotein and GlycA levels. Univariate and multivariate analyses were performed to evaluate lipoprotein variables and their relationship to ethnicity, disease activity, prednisone use, and hydroxychloroquine (HCQ) therapy.Results.Fifty-two patients were included over 229 visits. Adverse changes in lipoprotein variables with disease activity were demonstrated. For each point increase in the Systemic Lupus Erythematosus Disease Activity Index, there was a decrease in high-density lipoprotein (HDL) even after adjusting for corticosteroid use. Prednisone was associated with higher very low-density lipoprotein, low-density lipoprotein, HDL, and triglycerides. HCQ was associated with more favorable variables. GlycA levels were higher than in normal populations and increased with disease activity.Conclusion.Adverse changes in lipoprotein profiles were associated with SLE activity and prednisone therapy. This gives insight into mechanisms of atherosclerosis in SLE. Favorable lipoprotein variables occurred in those taking HCQ. GlycA increased with disease activity and was higher than in healthy populations.

Published: February 2016

Objective.African Americans in the United States undergo total knee arthroplasty (TKA) less often than whites, in part because of lower expectations among African Americans for successful surgery. Whether this lower expectation is justified is unknown. Our objective is to compare health-related quality of life (HRQOL) and satisfaction after TKA between African Americans and whites.Methods.A systematic review of English language articles using Medline, the Cochrane register, Embase (April 21, 2015), and a hand search of unlisted disparities journals was performed. Search terms included total knee replacement, quality of life, outcomes, and satisfaction. High-quality cohort studies that examined HRQOL in African Americans and white adults 6 months or more after TKA were included.Results.Of the 4781 studies screened by title, and 346 by abstract, 7 studies included race in their analysis. Results included 5570 TKA patients, 4077 whites (89%), and 482 (11%) blacks. Because studies used different outcome measures and were inconsistent in their adjustment for confounders, we could not perform a quantitative synthesis of results. In 5 studies, US blacks had worse pain, in 5 worse function, and in 1 less satisfaction 6 months to 2 years after TKA.Conclusion.US blacks may derive less benefit from TKA than whites as measured by HRQOL, pain, function, and satisfaction. Many studies assessing predictors of patient-related TKA outcomes fail to analyze race as a variable, which limited our study. More studies assessing the effect of race and socioeconomic factors on TKA outcome are needed.

Published: February 2016

Objective.It has been reported that organizing pneumonia (OP) develops when patients with rheumatoid arthritis (RA) are treated with biologic disease-modifying antirheumatic drugs (bDMARD). However, the clinical characteristics and pathophysiology of OP in RA remain unknown in patients treated with bDMARD. We investigated the clinical characteristics and cytokine profiles of patients with RA-OP treated with bDMARD or conventional synthetic DMARD (csDMARD).Methods.Twenty-four patients with RA who had developed OP were enrolled. These patients included 12 treated with bDMARD (bDMARD-OP subset) and 12 treated with csDMARD (csDMARD-OP subset). We compared the clinical characteristics and cytokine profiles between the patients with OP (OP subset, n = 24) and non-OP patients (non-OP subset, n = 29).Results.There was no significant difference in clinical characteristics between the OP subset and the non-OP subset. Four patients developed OP within 2 months of bDMARD administration. In the other 8 patients, OP developed more than 1 year after the initiation of bDMARD. OP improved with corticosteroid treatment in all bDMARD-OP patients. After OP improved, bDMARD were readministered in 6 patients, and no OP recurrence was observed in any of these patients. Our multivariate analysis revealed that serum levels of interferon-α (IFN-α), interleukin (IL)-1β, IL-6, IL-8, and interferon-γ–inducible protein 10 were significantly associated with the development of OP, although these cytokines tended to be lower in the bDMARD-OP subset than in the csDMARD-OP subset.Conclusion.OP is unlikely to be fatal in patients treated with bDMARD or csDMARD. IFN-α and proinflammatory cytokines are associated with the pathophysiology of OP in RA.

Dire notre expérience du sonore : nomination et référenciation
Authors: Cance Caroline , Dubois Danièle 
Published: February 2016

L’approche cognitive de la nomination présentée ici permet, à partir de la mise en œuvre de différents questionnements et de l’analyse des corpus provoqués, d’identifier un certain nombre des processus psychologiques et linguistiques qui permettent à des locuteurs francophones d’exprimer tant leur expérience sensible que leurs connaissances des qualités « objectives » imputées aux objets du monde sonore. Ce travail nous conduit à unifier les différentes conceptions de la référenciation (nomination/dénomination/désignation) non pas dans les seuls procédés linguistiques mais dans la généralité des processus à la fois linguistiques et psychologiques de mise en relation des ressources des langues et des réalités cognitives situées dans la diversité des pratiques humaines.
Polémique métalangagière sur une (dé)nomination : le terme « confrontation »
Authors: Garric Nathalie 
Published: February 2016

Le numérique définit des dispositifs discursifs qui favorisent des rencontres sources de nombreuses polémiques dont l’objet devient fréquemment le langage lui-même. Cette contribution s’intéresse à l’un de ces événements numériques déclenché par l’emploi de « confrontation » en réaction à l’expression référentielle dénominative « cette tension amicale », employée par F. Hollande. À l’issue de cette reformulation, l’espace des discours numériques reçoit de nombreux traitements métadiscursifs que nous abordons dans la linguistique populaire et du point de vue d’une sémantique discursive. Le traitement s’appuie sur une étude de la signification lexicale de « confrontation », à partir des discours lexicographiques pour progressivement problématiser l’unité dans le discours des acteurs du débat public et montrer les différents contributeurs à son interprétation discursive : le contexte textuel et énonciatif, le contexte discursif et ses communautés, le contexte interdiscursif.
Reformulation et non-reformulation du mot islamophobie. Une analyse des dynamiques de la nomination dans les commentaires des lecteurs
Authors: Calabrese Laura 
Published: February 2016

Cet article analyse un corpus de commentaires de lecteurs portant sur le problème public appelé islamophobie . Notre recherche vise à montrer les différentes stratégies discursives qu’utilisent les lecteurs pour défendre leur vision de ce phénomène. L’analyse du corpus révèle que le mot islamophobie a deux programmes de sens bien différenciés, à savoir « racisme anti-musulman » et « critique de la religion ». Les lecteurs qui défendent le premier vont employer le mot tel quel sans remettre en question ni le sens ni le référent, alors que ceux qui se focalisent sur le second vont produire une grande quantité d’énoncés métadiscursifs pour reformuler le sens et discuter le référent.
Images animées et excursions géographiques : une (ré)appropriation du terrain
Authors: Archambeau Olivier 
Published: February 2016

La géographie reste encore aujourd'hui l'une des disciplines les mieux placées pour mêler production audiovisuelle et recherche, d'une part, production scientifique et vulgarisation d'autre part. À travers la réalisation « d'expéditions » organisées par le Pôle image du département de géographie de l'Université Paris 8, nous essaierons de démontrer qu'à l'heure de Google Earth et des mondes virtuels communicants, il est important de remettre l'idée du voyage au centre d'un enseignement de géographie, en y associant la production de documentaires. Une proposition pédagogique qui voudrait favoriser la responsabilité, la liberté d'action, la pluralité des regards sur le monde et faire partager l'idée, par le film, que l'approche scientifique, l'exploration et les relations humaines ne peuvent être dissociées. Décrire la terre en images dans une société de l'image reste un objectif nécessaire. C'est en s'appuyant davantage sur le triptyque enseignement et pratiques du terrain, apprentissage des outils audiovisuels numériques et organisation de la diffusion des productions au niveau de la discipline, que la parole des géographes pourra être mieux entendue.
Le territoire entrepreneurial durable fondements théorique et analyse économique
Authors: Boutillier Sophie , Uzunidis Dimitri 
Published: February 2016

Qu’est-ce qu’un territoire entrepreneurial durable ? Pour analyser la dynamique de l’innovation dans les territoires industriels dont la reconversion passe par les activités de l’environnement et du développement durable, le chercheur doit répondre à plusieurs questions capitales : Comment définir l’entrepreneuriat innovant ? Comment favoriser l’entrepreneuriat éco-innovant ? Quels rôles et fonctions des institutions et de l’initiative individuelle ? Quelles opportunités et atouts pour l’entrepreneur éco-innovant ? Un territoire entrepreneurial durable peut être défini comme un ensemble territorialisé qui s’efforce de mobiliser des ressources sur le plan social, politique, économique, culturel et environnemental à l’intérieur d’un cadre institutionnel cohérent au service d’une stratégie clairement définie de développement économique et social respectueux de la préservation des ressources naturelles. Un de ses objectifs est la promotion de la création d’écoentreprises pour réussir un programme de réorientation de sa trajectoire de développement.

Episodic Excessive Blinking in Children
Authors: Mali Yasmin Poustchi , Simon John W. , Chaudhri Imran , Zobal-Ratner Jitka , Barry Gerard P. 
Published: February 2016

Purpose:
Many children present with excessive blinking. Categorization, associated conditions, and prognosis are controversial.

Methods:
All children with excessive blinking were reviewed, excluding those with known uveitis, glaucoma, or obvious eyelid abnormalities. Parents were telephoned for follow-up.

Results:
No ocular pathology was identified in 31 of 34 children with excessive blinking (91%). Parents were able to report a specific cause of blinking in 7 (21%). In 24 of 34 (71%), parents reported complete resolution of excessive blinking. No new ophthalmologic diagnoses were uncovered on follow-up.

Conclusions:
Episodes of excessive blinking rarely indicate neurologic disorders and frequently resolve spontaneously.

A Multi-tool to Reduce Nasolacrimal Stent Complications With the Home-Removable Farson Crawford Tube
Authors: Haering Celia , Beck Kara Byers , Arnold Robert W. 
Published: February 2016

Purpose:
Tear duct obstruction can be treated with probing and stenting, providing a reduced reoperation rate. A new instrument combining punctual dilation with the graduated diameter probe and bony-rasp was developed to assist the procedure.

Methods:
Laterality, type of nasolacrimal disorder, type of procedure, patient age, and postoperative outcome were monitored for one surgeon for two decades.

Results:
From 617 cases of pediatric tear duct obstruction, 494 used the bilateral, monocanalicular Farson method, yielding a 1.7% reoperation rate and 0.6% wire-strip rate. The nasolacrimal duct dilator rasp multi-tool, used since 1996, had a similarly low rate of complications.

Conclusions:
The Farson technique with the multi-tool provides an affordable, effective procedure for childhood nasolacrimal obstruction, allowing home removal of the stent.
