Abstract
We describe and employ a stacking procedure to investigate abundances derived from the low signal-to-noise ratio spectra obtained in the Carnegie RR Lyrae Survey (CARRS). We find iron metallicities that extend from [Fe/H] ∼ −2.5 to values at least as large as [Fe/H] ∼ −0.5 in the 274-spectrum CARRS RRc data set. We consider RRc sample contamination by high amplitude solar metallicity δ Scuti stars (HADS) at periods less than 0.3 days, where photometric discrimination between RRc and δ Scuti stars has proven to be problematic. We offer a spectroscopic discriminant, the well-marked overabundance of heavy elements, principally [Ba/H], that is a common, if not universal, characteristic of HADS of all periods and axial rotations. No bona fide RRc stars known to us have verified heavy-element overabundances. Three out of 34 stars in our sample with [Fe/H] > −0.7 exhibit anomalously strong features of Sr, Y, Zr, Ba, and many rare earths. However, carbon is not enhanced in these three stars, and we conclude that their elevated n-capture abundances have not been generated in interior neutron-capture nucleosynthesis. Contamination by HADS appears to be unimportant, and metal-rich RRc stars occur in approximately the same proportion in the Galactic field as do metal-rich RRab stars. An apparent dearth of metal-rich RRc is probably a statistical fluke. Finally, we show that RRc stars have a similar inverse period–metallicity relationship as has been found for RRab stars.

Abstract
We have established precise planet radii, semimajor axes, incident stellar fluxes, and stellar masses for 909 planets in 355 multi-planet systems discovered by Kepler. In this sample, we find that planets within a single multi-planet system have correlated sizes: each planet is more likely to be the size of its neighbor than a size drawn at random from the distribution of observed planet sizes. In systems with three or more planets, the planets tend to have a regular spacing: the orbital period ratios of adjacent pairs of planets are correlated. Furthermore, the orbital period ratios are smaller in systems with smaller planets, suggesting that the patterns in planet sizes and spacing are linked through formation and/or subsequent orbital dynamics. Yet, we find that essentially no planets have orbital period ratios smaller than 1.2, regardless of planet size. Using empirical mass–radius relationships, we estimate the mutual Hill separations of planet pairs. We find that 93% of the planet pairs are at least 10 mutual Hill radii apart, and that a spacing of ∼20 mutual Hill radii is most common. We also find that when comparing planet sizes, the outer planet is larger in 65% ± 0.4% of cases, and the typical ratio of the outer to inner planet size is positively correlated with the temperature difference between the planets. This could be the result of photo-evaporation.
Orbital Solution for the Spectroscopic Binary in the GW Ori Hierarchical Triple
Authors: Prato L. , Ruíz-Rodríguez Dary , Wasserman L. H. 
Published: January 2018

Abstract
We present the first double-lined orbital solution for the close binary in the GW Ori triple system. Using 12 epochs of infrared spectroscopy, we detected the lines of both stars in the inner pair, previously known as single-lined only. Our preliminary infrared orbital solution has an eccentricity of e = 0.21 ± 0.10, a period of P = 241.15 ± 0.72 days, and a mass ratio of q = 0.66 ± 0.13. We find a larger semi-amplitude for the primary star, K1 = 6.57 ± 1.00 km s−1, with an infrared-only solution compared to K1 = 4.41 ± 0.33 km s−1 with optical data from the literature, likely the result of line blending and veiling in the optical. The component spectral types correspond to G3 and K0 stars, with

values of 43 km s−1 and 50 km s−1, respectively. We obtained a flux ratio of α = 0.58 ± 0.14 in the H-band, allowing us to estimate individual masses of 3.2 and 2.7 M
⊙ for the primary and secondary, respectively, using evolutionary tracks. The tracks also yield a coeval age of 1 Myr for both components to within 1σ. GW Ori is surrounded by a circumbinary/circumtriple disk. A tertiary component has been detected in previous studies; however, we did not detect this component in our near-infrared spectra, probably the result of its relative faintness and blending in the absorption lines of these rapidly rotating stars. With these results, GW Ori joins the small number of classical T Tauri, double-lined spectroscopic binaries.
SDSS-IV MaNGA: Uncovering the Angular Momentum Content of Central and Satellite Early-type Galaxies

Abstract
We study 379 central and 159 satellite early-type galaxies with two-dimensional kinematics from the integral-field survey Mapping Nearby Galaxies at APO (MaNGA) to determine how their angular momentum content depends on stellar and halo mass. Using the Yang et al. group catalog, we identify central and satellite galaxies in groups with halo masses in the range

. As in previous work, we see a sharp dependence on stellar mass, in the sense that ∼70% of galaxies with stellar mass

tend to have very little rotation, while nearly all galaxies at lower mass show some net rotation. The ∼30% of high-mass galaxies that have significant rotation do not stand out in other galaxy properties, except for a higher incidence of ionized gas emission. Our data are consistent with recent simulation results suggesting that major merging and gas accretion have more impact on the rotational support of lower-mass galaxies. When carefully matching the stellar mass distributions, we find no residual differences in angular momentum content between satellite and central galaxies at the 20% level. Similarly, at fixed mass, galaxies have consistent rotation properties across a wide range of halo mass. However, we find that errors in classification of central and satellite galaxies with group finders systematically lower differences between satellite and central galaxies at a level that is comparable to current measurement uncertainties. To improve constraints, the impact of group-finding methods will have to be forward-modeled via mock catalogs.
Physical Conditions in Ultra-fast Outflows in AGN
Authors: Kraemer S. B. , Tombesi F. , Bottorff M. C. 
Published: January 2018

Abstract

XMM-Newton and Suzaku spectra of Active Galactic Nuclei (AGN) have revealed highly ionized gas, in the form of absorption lines from H-like and He-like Fe. Some of these absorbers, ultra-fast outflows (UFOs), have radial velocities of up to 0.25c. We have undertaken a detailed photoionization study of high-ionization Fe absorbers, both UFOs and non-UFOs, in a sample of AGN observed by XMM-Newton. We find that the heating and cooling processes in UFOs are Compton-dominated, unlike the non-UFOs. Both types are characterized by force multipliers on the order of unity, which suggest that they cannot be radiatively accelerated in sub-Eddington AGN, unless they were much less ionized at their point of origin. However, such highly ionized gas can be accelerated via a magneto-hydrodynamic (MHD) wind. We explore this possibility by applying a cold MHD flow model to the UFO in the well-studied Seyfert galaxy, NGC 4151. We find that the UFO can be accelerated along magnetic streamlines anchored in the accretion disk. In the process, we have been able to constrain the magnetic field strength and the magnetic pressure in the UFO and have determined that the system is not in magnetic/gravitational equipartition. Open questions include the variability of the UFOs and the apparent lack of non-UFOs in UFO sources.

Abstract
We examine the quenched fraction of central and satellite galaxies as a function of galaxy stellar mass, halo mass, and the matter density of their large-scale environment. Matter densities are inferred from our ELUCID simulation, a constrained simulation of the local universe sampled by SDSS, while halo masses and central/satellite classification are taken from the galaxy group catalog of Yang et al. The quenched fraction for the total population increases systematically with the three quantities. We find that the “environmental quenching efficiency,” which quantifies the quenched fraction as a function of halo mass, is independent of stellar mass. And this independence is the origin of the stellar mass independence of density-based quenching efficiency found in previous studies. Considering centrals and satellites separately, we find that the two populations follow similar correlations of quenching efficiency with halo mass and stellar mass, suggesting that they have experienced similar quenching processes in their host halo. We demonstrate that satellite quenching alone cannot account for the environmental quenching efficiency of the total galaxy population, and that the difference between the two populations found previously arises mainly from the fact that centrals and satellites of the same stellar mass reside, on average, in halos of different mass. After removing these effects of halo mass and stellar mass, there remains a weak, but significant, residual dependence on environmental density, which is eliminated when halo assembly bias is taken into account. Our results therefore indicate that halo mass is the prime environmental parameter that regulates the quenching of both centrals and satellites.
L’exécution des décisions de justice face à l’ordre public
Authors: Grabias Fanny 
Published: January 2018

Sujet classique au sein de la littérature juridique, l’exécution des décisions de justice face à l’ordre public l’est certainement moins lorsqu’il s’agit de l’interroger à propos des seules décisions du juge administratif. Si, en effet, la question de leur exécution a suscité de nombreux écrits de la part de la doctrine, c’est surtout en raison des pouvoirs limités dont disposait le juge pour s’opposer à la récalcitrance de l’Administration. Les nombreuses évolutions qui ont affecté le droit administratif et le contentieux administratif depuis les années 90 ont cependant permis de rendre à la justice administrative l’efficacité qui lui a pendant longtemps fait défaut. S’agissant de la limite posée par l’ordre public en revanche, le silence de la doctrine demeure entier : ce dernier peut-il, et le cas échéant dans quelle mesure, faire obstacle à l’exécution des décisions du juge administratif ? Théoriquement, l’importance de ce conflit ne fait pas de doute : exécution des décisions de justice et protection de l’ordre public sont deux obligations de même valeur juridique qui incombent à l’administration et qui peuvent se neutraliser, le respect de l’une pouvant conduire à la violation de l’autre. Dans une telle hypothèse, l’Administration doit procéder à l’établissement d’un bilan négatif. Pour autant, la jurisprudence récente semble aller dans le sens d’un renforcement de l’obligation d’exécution des décisions de justice, de sorte que le nécessaire respect de l’ordre public ne puisse plus justifier l’inexécution de la chose jugée. Plus encore, la réalité même de ce conflit s’agissant des décisions du juge administratif demeure relativement faible. D’une part en effet, l’ordre public constitue un obstacle dont le champ d’application est limité, puisqu’entendu dans l’acception qui est la sienne en matière de police, il n’a vocation à jouer que dans les hypothèses où le concours de la force publique est nécessaire à l’exécution de la chose jugée. D’autre part, sur le plan de la responsabilité de l’État, il n’influence plus le sort des demandes d’indemnité en cas d’inexécution de la décision juridictionnelle : en tout état de cause, le justiciable a droit à réparation. Aussi les limites à l’exécution des décisions du juge administratif peuvent-elles, peut–être, être recherchées dans d’autres considérations juridiques telles que la sécurité juridique. Mais elles influencent alors sans doute davantage le contenu même de la décision juridictionnelle que son exécution.
Introduction à « Pratiques de consciences »
Authors: Midol Nancy , Chenault Marceau 
Published: January 2018

Les activités en STAPS sont en première ligne pour des expériences sensibles et cognitives sur les études des pratiques de consciences. Dans le domaine des apprentissages, nous n’avons pas assez pris en compte l’intelligence du corps inconscient, celui qui réagit à l’environnement sans qu’on ait pu en prendre conscience et qui anticipe l’action consciente. La conscience est un rapport au monde et questionne l’interface entre l’intériorité et l’extériorité de l’être. Ce dossier basé sur l’analyse de situations et d’expériences en contexte d’apnée, de danse, de rituel chamanique, d’arts martiaux, de taiji quan, de qigong et de méditation, de course à pied…, offre un matériel riche de données. Le domaine des STAPS pourrait habiter une vraie science interdisciplinaire en prenant en compte les études sur la cognition incarnée et concevoir l’apprentissage à l’interface des sciences (éthologie, anthropologie, écologie, physiologie, enaction…) et de la philosophie. Les scientifiques nous proposent de changer d’échelle pour interpréter le monde et soi-même dans l’univers auquel nous appartenons. Les sciences sont en train de déplacer le curseur de l’individu vers les intrications du multiple et des transformations selon une approche holistique nouvelle. « Pratiques de consciences » est une entrée pertinente pour ce grand chambardement.
Hybridations ontologiques de pratiques de conscience sous l’effet de la mondialisation
Authors: McEwen Laurel , Midol Nancy 
Published: January 2018

Quels sont les effets de la mondialisation sur des pratiques qui touchent à l’intimité, que ce soient des pratiques de santé, de loisir, de spiritualité… comme les néo-chamanismes qui se déploient en Europe et ailleurs depuis le XX e siècle et massivement depuis les années 2000 ? Comment des pratiques issues de sociétés aux ontologies différentes et même divergentes (il y a discontinuité entre les humains et les non-humains versus il y a continuité…) peuvent-elles être délocalisées, déracinées et s’acclimater dans d’autres cultures pour s’y implanter ? Quels processus de prise de conscience cela implique-t-il chez les pratiquants et sur leur connaissance du monde qui les environne ? C’est à quoi l’article répond dans sa première partie. Dans la seconde, il est répondu au phénomène symétrique mais inverse, à savoir qu’est-ce qui est issu de notre culture occidentale, de France même, comme la plongée en apnée, et qui traverse les frontières ontologiques du « naturalisme » pour produire des formes « aesthétiques » nouvelles qui récupèrent des éléments d’ontologies animistes, totémistes et analogistes pour prendre finalement une dimension cosmique ?
« Quand l’esprit ne peut sentir le corps » : dépasser le dualisme cartésien du corps-esprit avec la pratique du qigong
Authors: Winiger Fabian , Chenault Marceau , Midol Nancy 
Published: January 2018

La discussion suivante met en évidence des parallèles entre les « circuits d’information » décrits dans le travail de Yuasa Yasuo (1925-2005) et les expériences rapportées lors d’un travail de terrain ethnographique effectué avec des praticiens de qigong du style « Zhineng qigong ». Nous observons leur progression dans quatre étapes successives d’unité corps-esprit qui aboutissent au dépassement de la séparation cartésienne entre le corps et l’esprit et finalement une guérison de leur maladie. J’illustre cette progression avec le cas clinique de Luca, un homme de 32 ans né en Italie, qui explique son rétablissement d’une blessure invalidante au bas du dos en termes de « réunification » de son corps, qi et esprit grâce au zhineng qigong . J’argumente que le qigong et les pratiques comparables de la conscience du corps impliquent des techniques de mouvement, de respiration, de visualisation et, plus encore, façonnent une nouvelle relation entre le corps et l’esprit, soi et les autres, qui peut être vécue comme profondément thérapeutique.
Méditation et présence attentive : étude comparée de pratiques de consciences en Asie et en France
Authors: Hamard Albin , Chenault Marceau 
Published: January 2018

L’objectif de cet article est de comparer diverses pratiques méditatives en Asie et en France afin de caractériser les dénominateurs communs et les variations de ces pratiques de consciences. Les auteurs s’appuient sur une ethnographie multi-site : des monastères en Himalaya bouddhiste, un institut de médecine traditionnelle en Chine, des ermitages et centres de méditation tibétains en France, ainsi que des immersions dans des formations françaises à la MBSR et au qigong. L’observation de la méditation dans ces contextes variés amène à distinguer selon les sites des pratiques, des techniques et des gestes intérieurs distincts. L’analyse conduit aussi à identifier quatre types de pratiques méditatives : concentrative, ouverte, introspective, non orientée. Ces résultats offrent des éléments de réflexion intéressants sur la transformation des pratiques méditatives en Europe et leur intégration dans les milieux éducatifs ou de santé. Il s’agit finalement de contribuer à l’émergence de nouvelles pistes conceptuelles par l’étude des techniques et pratiques de conscience.
Truncation of the Murine Neonatal Fc Receptor Cytoplasmic Tail Does Not Alter IgG Metabolism or Transport In Vivo

Abstract
The neonatal Fc receptor (FcRn) is involved in IgG metabolism and transport in placental mammals. However, whether FcRn is responsible for IgG transfer from maternal serum to colostrum/milk is controversial. Interestingly, large domestic animals, such as cows, pigs, sheep, and horses, in which passive IgG transfer is exclusively completed via colostrum/milk, all express an FcRn α-chain that is shorter in the cytoplasmic tail (CYT) than its counterparts in humans and rodents. To address whether the length variation has any functional significance, we performed in vitro experiments using the Transwell system with the MDCK cell line stably transfected with various FcRn constructs; these clearly suggested that truncation of the CYT tail caused a polar change in IgG transfer. However, we observed no evidence supporting functional changes in IgG in vivo using mice in which the FcRn CYT was precisely truncated. These data suggest that the length variation in FcRn is not functionally associated with passive IgG transfer routes in mammals.
Cytopathological examination of bronchoalveolar lavage fluid in diagnosis of pulmonary alveolar proteinosis
Authors: Kishore Manjari , Kaushal Manju , Deepak Desh , Kumari Manju 
Published: January 2018

AbstractPulmonary alveolar proteinosis (PAP) is a rare disease characterized by the deposition of extracellular lipoproteinaceous material within the air spaces. Although the diagnosis is mainly based on histopathological findings, sometimes, the diagnostic yield of transbronchial and even open lung biopsy can be unsatisfactory. The advantage with bronchoalveolar lavage (BAL) cytology is that apart from being safer for the patient, it can sample a much wider area and help in giving an early diagnosis and treatment to the patient. Herein, we present a case of PAP diagnosed on BAL fluid cytology in an elderly female.
External ophthalmomyiasis by Oestrus
ovis: A case report from Davangere

Published: January 2018

Abstract:External ophthalmomyiasis is an infestation of the eye with larvae of Dermatobia hominis or Oestrus ovis (sheep bot fly). We describe a case of ophthalmomyiasis in a 38-year-old male, who presented with ocular foreign body sensation, redness, pain, and watering of the eye. The causative larvae were removed and sent to the laboratory for identification. By studying morphological features, it was identified as the first instar larvae of O. ovis. The patient was put on topical and oral antibiotics but was lost to follow-up. This is probably the first report from this part of Karnataka.
Risk factors for intestinal colonization with vancomycin resistant enterococci’ A prospective study in a level III pediatric intensive care unit
Authors: Amberpet Rajesh , Sistla Sujatha , Parija Subhash Chandra , Rameshkumar Ramachandran 
Published: January 2018

Abstract
PURPOSE: Vancomycin-resistant enterococci (VRE) emerged as one of the major nosocomial pathogens across the globe. Gut colonization rate with VRE is higher in patients admitted to intensive care units (ICUs) due to the higher antibiotic pressure. VRE colonization increases the risk of developing infection up to 5–10 folds. The aim of this study was to determine the rates of VRE colonization among the patients admitted to pediatric ICU (PICU) and risk factors associated with it.
MATERIALS AND METHODS: Rectal swabs were collected after 48 h of admission to PICU from 198 patients. The samples were inoculated onto bile esculin sodium azide agar with 6 mg/ml of vancomycin. Growth on this medium was identified by the standard biochemical test, and minimum inhibitory concentration of vancomycin and teicoplanin was detected by agar dilution method. Resistance genes for vancomycin were detected by polymerase chain reaction. Risk factors were assessed by logistic regression analysis.
RESULTS: The rates of VRE colonization in patients admitted to PICU was 18.6%. The majority of the isolates were Enterococcus faecium (75.6%) followed by Enterococcus faecalis (24.4%). One patient acquired a VRE bloodstream infection (2.6%) among colonized patients, and none of the noncolonized patients acquired the infection. Consumption of vancomycin was found to be the only risk factor significantly associated with VRE colonization.
CONCLUSION: Routine surveillance and isolation of patients found to be VRE colonized may not be possible in tertiary care hospitals; however, educating health-care workers, promoting handwashing with antiseptic soaps or solutions, and antibiotic Stewardship policy may help in the reduction of vancomycin resistance and VRE colonization.
