Abstract
On 2017 May 15, the FERMI/LAT gamma-ray telescope observed a transient source not present in any previous high-energy catalog: J1544–0649. It was visible for two consecutive weeks, with a flux peak on May 21. Subsequently observed by a Swift/XRT follow-up starting on May 26, the X-ray counterpart position was coincident with the optical transient ASASSN-17gs = AT2017egv, detected on May 25, with a potential host galaxy at z = 0.171. We conducted a 4-month follow-up in radio (Effelsberg-100 m) and optical (San Pedro Mártir, 2.1 m) bands, in order to build the overall Spectral Energy Distribution (SED) of this object. The radio data from 5 to 15 GHz confirmed the flat spectrum of the source, favoring a line of sight close to the jet axis, not showing significant variability in the explored post-burst time window. The Rx ratio, a common indicator of radio loudness, gives a value at the border between the radio-loud and radio-quiet active galactic nuclei (AGNs) populations. The CaII H&K break value (0.29 ± 0.05) is compatible with the range expected for the long-sought intermediate population between BL Lacs and FRI radio galaxies. An overall SED fitting from the radio to gamma-ray band shows properties typical of a low-power BL Lac. As a whole, these results suggest that this transient could be a new example of the recently discovered class of radio-weak BL Lac, showing for the first time a flare in the gamma/X-ray bands.

Abstract
We present new radial velocity and trigonometric distance measurements indicating that the unusually red and photometrically variable T2 dwarf 2MASS J13243553+6358281 is a member of the young (∼150 Myr) AB Doradus moving group (ABDMG) based on its space velocity. We estimate its model-dependent mass in the range 11–12 M
Jup at the age of the ABDMG, and its trigonometric distance of 12.7 ± 1.5 pc makes it one of the nearest known isolated planetary-mass objects. The unusually red continuum of 2MASS J13243553+6358281 in the near-infrared was previously suspected to be caused by an unresolved L + T brown dwarf binary, although it was never observed with high spatial resolution imaging. This new evidence of youth suggests that a low surface gravity may be sufficient to explain this peculiar feature. Using the new parallax we find that its absolute J-band magnitude is ∼0.4 mag fainter than equivalent-type field brown dwarfs, suggesting that the binary hypothesis is unlikely. The fundamental properties of 2MASS J13243553+6358281 follow the spectral type sequence of other known high-likelihood members of the ABDMG. The effective temperature of 2MASS J13243553+6358281 provides the first precise constraint on the L/T transition at a known young age and indicates that it happens at a temperature of ∼1150 K at ∼150 Myr, compared to ∼1250 K for field brown dwarfs.

Abstract
We report the discovery and initial follow-up of a double neutron star (DNS) system, PSR J1946+2052, with the Arecibo L-Band Feed Array pulsar (PALFA) survey. PSR J1946+2052 is a 17 ms pulsar in a 1.88 hr, eccentric (e = 0.06) orbit with a ≳1.2 M
⊙ companion. We have used the Jansky Very Large Array to localize PSR J1946+2052 to a precision of 0.″09 using a new phase binning mode. We have searched multiwavelength catalogs for coincident sources but did not find any counterparts. The improved position enabled a measurement of the spin period derivative of the pulsar (

); the small inferred magnetic field strength at the surface (B

S
= 4 × 109 G) indicates that this pulsar has been recycled. This and the orbital eccentricity lead to the conclusion that PSR J1946+2052 is in a DNS system. Among all known radio pulsars in DNS systems, PSR J1946+2052 has the shortest orbital period and the shortest estimated merger timescale, 46 Myr; at that time it will display the largest spin effects on gravitational-wave waveforms of any such system discovered to date. We have measured the advance of periastron passage for this system,

, implying a total system mass of only 2.50 ± 0.04 M
⊙, so it is among the lowest-mass DNS systems. This total mass measurement combined with the minimum companion mass constrains the pulsar mass to ≲1.3 M

Objective.To investigate whether adalimumab (ADA) reduces whole-body (WB-) magnetic resonance imaging (MRI) indices for inflammation in the entheses, peripheral joints, sacroiliac joints, spine, and the entire body in patients with axial spondyloarthritis (axSpA).Methods.An investigator-initiated, randomized, placebo-controlled, double-blinded 48-week followup trial included 49 patients with axSpA, who had Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥ 4.0 despite treatment with nonsteroidal antiinflammatory drugs and a clinical indication for tumor necrosis factor inhibitor treatment. Patients were randomized to subcutaneous ADA 40 mg or placebo every other week for 6 weeks; thereafter, all patients received ADA. Conventional MRI and WBMRI were performed at weeks 0, 6, 24, and 48. The primary WBMRI endpoint was the proportion of patients with an improvement in WBMRI total inflammation index above the smallest detectable change (SDC) at Week 6.Results.The primary WBMRI endpoint (improvement of SDC > 2.3) was met in 11 (44%) patients in the ADA group and 3 (13%) patients in the placebo group (p = 0.025, Fisher’s exact test). The primary conventional MRI endpoint, the minimally important change in Spondyloarthritis Research Consortium of Canada Spine MRI Inflammation Index at Week 6, was achieved by 9 (36%) patients in the ADA group and 4 (17%) patients in the placebo group (p = 0.20). The primary clinical endpoint, BASDAI reduction > 50% or 2.0 at Week 24, was attained by 32 (65%) patients.Conclusion.ADA provided significant reductions in WBMRI indices of peripheral, axial, and whole-body inflammation in patients with axSpA. WBMRI is promising for objective assessment and monitoring of peripheral and axial disease activity in future clinical trials.

Published: February 2018

Objective.To evaluate the types of experiences and treatment access challenges of patients with psoriatic arthritis (PsA) using self-reported online narratives.Methods.English-language patient narratives reported between January 2010 and May 2016 were collected from 31 online sources (general health social networking sites, disease-focused patient forums, treatment reviews, general health forums, mainstream social media sites) for analysis of functional impairment and 40 online sources for assessment of barriers to treatment. Using natural language processing and manual curation, patient-reported experiences were categorized into 6 high-level concepts of functional impairment [social, physical, emotional, cognitive, role activity (SPEC-R), and general] and 6 categories to determine barriers to treatment access (coverage ineligibility, out-of-pocket cost, issues with assistance programs, clinical ineligibility, formulary placement/sequence, doctor guidance). The SPEC-R categorization was also applied to 3 validated PsA patient-reported outcome (PRO) instruments to evaluate their capacity to collect lower-level subconcepts extracted from patient narratives.Results.Of 15,390 narratives collected from 3139 patients with PsA for exploratory analysis, physical concepts were the most common (81.5%), followed by emotional (50.7%), cognitive (20.0%), role activity (8.1%), and social (5.6%) concepts. Cognitive impairments and disease burden on family and parenting were not recorded by PsA PRO instruments. The most commonly cited barriers to treatment were coverage ineligibility (51.6%) and high out-of-pocket expenses (31.7%).Conclusion.Patients often discussed physical and emotional implications of PsA in online platforms; some commonly used PRO instruments in PsA may not identify cognitive issues or parenting/family burden. Nearly one-third of patients with PsA reported access barriers to treatment.

Published: February 2018

Objective.To determine the association between crescents and renal outcomes, and the implications on therapeutic choices.Methods.There were 231 patients with biopsy-proven proliferative lupus nephritis (PLN) who were divided into 4 groups: 59 patients were in the noncrescent group (NC); 59 patients exclusively with segmental crescents were in the segmental crescent group (SC); patients with circumferential crescents were categorized into 2 groups according to the crescentic ratio (C1 had 64 patients with ≤ 25%, and C2 had 49 patients with > 25%). Their baseline laboratory tests, histopathological manifestations, and outcomes were compared.Results.Remission rates in NC, SC, C1, and C2 groups were 92.1%, 85.4%, 95.0%, and 76.1%, respectively. Fewer patients in the C2 group achieved complete remission than the other 3 groups. For longterm outcomes evaluated by serum creatinine (SCr) doubling or endstage renal disease (ESRD), the renal survival rate was lowest in the C2 group (p = 0.003). Including clinical and pathological variables in the Cox proportional hazard regression model separately, the multivariate analysis revealed that these were independent risk factors for SCr doubling or ESRD: baseline SCr (with every 1 mg/dl increase: HR = 1.834, 95% CI 1.465–2.296; p < 0.001), hemoglobin (with every 1 g/l increase: HR = 0.970, 95% CI 0.947–0.992; p = 0.009), the proportions of cellular crescents (with every 1% increase: HR = 1.040, 95% CI 1.015–1.066; p = 0.002) and fibrocellular crescents (with every 1% increase: HR = 1.085, 95% CI 1.013–1.163; p = 0.020), and severe renal tubular atrophy (HR = 5.348, 95% CI 1.278–22.373; p = 0.022).Conclusion.PLN with crescents > 25% had worse renal outcomes both in short and long terms. Proportions of cellular and fibrocellular crescents were independent risk factors for poor renal survival.
Les massiers dans la Maison du roi de la monarchie espagnole
Authors: Arroyo Félix Labrador 
Published: February 2018

Au cours des dernières décennies, grâce à une nouvelle méthodologie, les études sur la cour et les différents départements et secteurs qui la configuraient se sont multipliées. Dans ce contexte, l’analyse de l’une des composantes fondamentales de la cour, la Maison royale, acquiert une importance particulière, car elle est le lieu de l’articulation politique dans les monarchies dynastiques européennes en général et la monarchie hispanique en particulier : elle devient l’élément intégrateur des élites des royaumes qui la composent. En ce sens, dans le cadre des études et des approches méthodologiques du professeur Martínez Millán et de son équipe, dans lequel s’insère ce travail, a été menée à bien l’étude minutieuse d’un métier qui joue un rôle important dans les cérémonies publiques du roi, celui des massiers, office d’honneur qui existe encore et participe activement aux cérémonies publiques. J’entends ainsi analyser ici son évolution, son rôle et sa participation aux cérémonies du pouvoir à travers les différentes dispositions organisationnelles et normalisatrices élaborées essentiellement à l’époque de Philippe III, grâce à la documentation conservée à l’Instituto Valencia de Don Juan, à Madrid, à l’Archivo General de Palacio de Madrid, à la Biblioteca Nacional de España et, dans une moindre mesure, à la Sección de Casas y Sitios Reales del Archivo General de Simancas. Nous étudierons les changements qui ont affecté ce métier, dépendant de l’intendant des Écuries, aussi bien dans ses fonctions que dans ses obligations et rétributions ou dans sa participation aux cérémonies publiques consignées dans les Étiquettes générales du palais. On examinera également le cursus honorum des personnes qui l’exerçaient.
Classification of thyroid fine-needle aspiration cytology into Bethesda categories: An institutional experience and review of the literature
Authors: Alshaikh Safa , Harb Zainab , Aljufairi Eman , Almahari S. Ali 
Published: February 2018

Background:
Fine-needle aspiration cytology (FNAC) of thyroid is the initial screening test for thyroid nodules. The Bethesda system classifies thyroid FNAC into six categories. Each category is linked to a malignancy risk and has a recommended clinical management. The aim of this study is to analyze the thyroid cytology smears by Bethesda system and to correlate the diagnosis of cytopathology with histopathology, whenever surgery was done.

Materials and Methods:
This study presents our experience with the Bethesda system in 681 thyroid FNAs from 632 patients in the period between January 2013 and December 2016.

Results:
Categories were as follows: 10.1% were Category I (nondiagnostic), 68.8% Category II (benign), 12.4% were Category III (atypia of undetermined significance), 2.9% were Category IV (suspicious for follicular neoplasm), 2.6% were Category V (suspicious for malignancy), and 4.1% were Category VI (malignant). Surgery was done on 126 nodules from 119 patients with an overall rate of malignancy of 27.8% (35/126 nodules).

Conclusion:
The Bethesda System for Reporting Thyroid Cytopathology proved to be an excellent reporting system.

Abstract. Widespread efforts to abate ozone (O3) smog have significantly reduced emissions of nitrogen oxides (NOx) over the past 2 decades in the Southeast US, a place heavily influenced by both anthropogenic and biogenic emissions. How reactive nitrogen speciation responds to the reduction in NOx emissions in this region remains to be elucidated. Here we exploit aircraft measurements from ICARTT (July–August 2004), SENEX (June–July 2013), and SEAC4RS (August–September 2013) and long-term ground measurement networks alongside a global chemistry–climate model to examine decadal changes in summertime reactive oxidized nitrogen (RON) and ozone over the Southeast US. We show that our model can reproduce the mean vertical profiles of major RON species and the total (NOy) in both 2004 and 2013. Among the major RON species, nitric acid (HNO3) is dominant (∼ 42–45 %), followed by NOx (31 %), total peroxy nitrates (ΣPNs; 14 %), and total alkyl nitrates (ΣANs; 9–12 %) on a regional scale. We find that most RON species, including NOx, ΣPNs, and HNO3, decline proportionally with decreasing NOx emissions in this region, leading to a similar decline in NOy. This linear response might be in part due to the nearly constant summertime supply of biogenic VOC emissions in this region. Our model captures the observed relative change in RON and surface ozone from 2004 to 2013. Model sensitivity tests indicate that further reductions of NOx emissions will lead to a continued decline in surface ozone and less frequent high-ozone events.

MOUVANCES IDENTITAIRES ET INFLEXIONS CORPORELLES DE LA PAROLE DANS YUKONSTYLE DE SARAH BERTHIAUME ET NACRE C DE DOMINICK PARENTEAU-LEBEUF
Authors: CYR CATHERINE 
Published: February 2018

« Le corps est le bougé de l’âme », écrit le philosophe Jean-Luc Nancy dans ses 58 indices sur le corps et Extension de l’âme. Au théâtre, cette mouvance d’une intériorité qui affleure sur le corps trouve sur la scène, dans le jeu et la présence de l’acteur, sa pleine incarnation. Or, en amont de celle-ci préexiste souvent au corps de chair un corps de papier. En effet, entre les pages du texte dramatique que préoccupe la corporéité y a-t-il souvent un « déjà-là » du corps qui s’énonce. Tissé de mots, ce corps est à la fois tout entier tendu vers la scène et indépendant de toute actualisation scénique (dont il pourra, néanmoins, se révéler un ressort important). Porteur de différents discours — souvent noués à la question de l’identité —, le corps qui se déploie sur la page se donne à lire à travers différentes poétiques d’énonciation qui, peu à peu, en tracent les contours. Cet article analyse les rapports qui se nouent entre ces poétiques énonciatives et les imaginaires du corps rencontrés dans les pièces Yukonstyle, de Sarah Berthiaume, et Nacre C, de Dominick Parenteau-Lebeuf. Il s’agit d’étudier la dynamique établie entre l’imaginaire corporel et l’énonciation, et de voir comment, par le biais de poétiques énonciatives différentes — mécanique dissociative et narrativité mobile chez Sarah Berthiaume, abolition du « Je » énonciatif chez Parenteau-Lebeuf —, chaque pièce propose, à travers la trajectoire de la parole, un parcours extatique, soit une échappée hors de soi, et parfois hors du monde. Cyr observe comment cette parole, dissociée, inassignable ou fractionnée, rend compte d’un corps désinvesti, provisoirement ou définitivement étranger à lui-même.

Published: February 2018

Dans cet article, l’auteur met en lumière les innovations poétiques opérées par les
quatre textes publiés dans la collection « Les Romans de la jeune génération » (1931-1932).
Plus spécifiquement, il montre comment « la vie », vue comme idéal philosophique structurant
de l’espace social canadien-français de la décennie 1930, s’infuse dans les formes et les
discours romanesques des quatre titres qui composent l’éphémère collection créée par
l’éditeur Albert Lévesque : Dans les ombres, d’Éva Senécal ; La chair
décevante, de Jovette-Alice Bernier ; Dilettante, de Claude Robillard ; et
L’initiatrice, de Rex Desmarchais. Après une présentation des auteurs et du
contexte sociolittéraire entourant la création de la collection, Rannaud aborde les textes
en isolant trois variables : le genre romanesque, la représentation de la parole écrite ou
lue, et les thèmes et discours dominants de la série.
Direito ao teletrabalho: reflexões sobre a imposição do teletrabalho ao empregador sob o prisma dos direitos fundamentais
Authors: Fincato Denise Pires , Puantá Eduardo Coletto 
Published: February 2018

O presente estudo se propõe à investigar se é possível a imposição do teletrabalho pelo empregado frente ao empregador e se haveriam fundamentos jurídicos para tanto. O tema é relevante diante do vazio legislativo e por gerar aparente inversão de forças na relação empregatícia. Tem-se como hipótese inicial que em algumas situações seria possível a depender do caso concreto e do embate de direitos fundamentais. Metodologicamente, o estudo se realiza a partir da abordagem hipotético-dedutiva, interpretação sociológica e procedimentos fenomenológicos, estruturais e funcionalistas. Tomando como base o caso de um trabalhador com câncer que manteve seu vínculo empregatício teletrabalhando, passa-se a analisar os conceitos de teletrabalho e saúde. Verificou-se que, por motivos de saúde é possível teletrabalhar, desde que respeitados certos limites e preenchidos alguns requisitos. Conclui pela possibilidade de imposição de modalidade de trabalho (teletrabalho, na hipótese) ao empregador, nos casos em que compatível com o trabalho prestado e com o estado de saúde do trabalhador, objetivando manter ou buscar plenitude à sua saúde, observando-se a arguição da reserva do possível como provável atuação patronal

Authors: Wedy Gabriel de Jesus Tedesco 
Published: February 2018

O texto aborda o desenvolvimento (sustentável) e a Ideia de Justiça segundo Amartya Sen sob a perspectiva da tutela ambiental, do desenvolvimento econômico, da governança e especialmente da inclusão social. É procedida uma forte crítica ao utilitarismo e defendida a liberdade como o caminho para se alcançar o desenvolvimento (sustentável). No texto, a insuficiência do Produto Interno Bruto como único índice de mensuração do desenvolvimento é criticado sob perspectivas de desenvolvimento humano, tutela ambiental, desenvolvimento econômico e de governança. De acordo com o artigo, o desenvolvimento sustentável pode apenas ser alcançado juntamente com o desenvolvimento humano, proteção ambiental, desenvolvimento econômico e governança de modo harmônico e sempre com liberdade em um Estado Democrático de Direito.
