Accurate Computation of Light Curves and the Rossiter–McLaughlin Effect in Multibody Eclipsing Systems
Authors: Short Donald R , Orosz Jerome A , Windmiller Gur , Welsh William F 
Published: December 2018

Abstract
We present an efficient method for computing the visible flux for each body during a multibody eclipsing event for all commonly used limb-darkening laws. Our approach follows the idea put forth by Pál to apply Green’s theorem on the limb-darkening integral, thus transforming the two-dimensional flux integral over the visible disk into a one-dimensional integral over the visible boundary. We implement this idea through an iterative process that combines a fast method for describing the visible boundary of each body with a fast numerical integration scheme to compute the integrals. For the two-body case, our method compares well in speed with both that of Mandel & Agol and that of Giménez. The strength of the method is that it works for any number of spherical bodies with a computational accuracy that is adjustable through the use of a tolerance parameter. Most significantly, the method offers two main advantages over previously used techniques: (i) it can employ a multitude of limb-darkening laws, including all of the commonly used ones; and (ii) it can compute the Rossiter–McLaughlin effect for rigid-body rotation with an arbitrary orientation of the rotation axis using any of these limb-darkening laws. In addition, we can compute the Rossiter–McLaughlin effect for stars exhibiting differential rotation using the quadratic limb-darkening law. We provide the mathematical background for the method and explain in detail how to implement the technique with the help of several examples and codes that we make available.

Abstract
We present an optical to near-infrared transmission spectrum of the inflated hot Jupiter WASP-52b using three transit observations from the Space Telescope Imaging Spectrograph mounted on the Hubble Space Telescope, combined with Spitzer/Infrared Array Camera photometry at 3.6 and 4.5 μm. Since WASP-52 is a moderately active (log(L
x/L
bol) = −4.7) star, we correct the transit light curves for the effect of stellar activity using ground-based photometric monitoring data from the All-sky Automated Survey for Supernovae (ASAS-SN) and Tennessee State University’s Automatic Imaging Telescope. We bin the data in 38 spectrophotometric light curves from 0.29 to 4.5 μm and measure the transit depths to a median precision of 90 ppm. We compare the transmission spectrum to a grid of forward atmospheric models and find that our results are consistent with a cloudy spectrum and evidence of sodium at 2.3σ confidence, but we find no observable evidence of potassium absorption even in the narrowest spectroscopic channel. We find that the optical transmission spectrum of WASP-52b is similar to that of the well-studied inflated hot Jupiter HAT-P-1b, which has comparable surface gravity, equilibrium temperature, mass, radius, and stellar irradiation levels. At longer wavelengths, however, the best-fitting models for WASP-52b and HAT-P-1b predict quite dissimilar properties, which could be confirmed with observations at wavelengths longer than ∼1 μm. The identification of planets with common atmospheric properties and similar system parameters will be insightful for comparative atmospheric studies with the James Webb Space Telescope.
Investigating Inner and Large-scale Physical Environments of IRAS 17008-4040 and IRAS 17009-4042 toward L = 345.°5, B = 0.°3

Published: December 2018

Abstract
We present a multiwavelength observational study of IRAS 17008-4040 and IRAS 17009-4042 to probe the star formation (SF) mechanisms operational in both the sites. Each IRAS site is embedded within a massive ATLASGAL 870 μm clump (∼2430–2900 M
⊙), and several parsec-scale filaments at 160 μm are radially directed toward these clumps (at T

d
∼ 25–32 K). The analysis of the Spitzer and VVV photometric data depicts a group of infrared-excess sources toward both the clumps, suggesting the ongoing SF activities. In each IRAS site, high-resolution GMRT radio maps at 0.61 and 1.28 GHz confirm the presence of H ii regions, which are powered by B-type stars. In the site IRAS 17008-4040, a previously known O-star candidate without an H ii region is identified as an infrared counterpart of the 6.7 GHz methanol maser emission (i.e., IRcmme). Based on the Very Large Telescope/NAOS-CONICA adaptive-optics L′ image (resolution ∼0.″1), the source IRcmme is resolved into two objects (i.e., IRcmme1 and IRcmme2) within a scale of 900 au that are found to be associated with the Atacama Large Millimeter/submillimeter Array core G345.50M. IRcmme1 is characterized as the main accreting high mass protostellar object candidate before the onset of an ultracompact H ii region. In the site IRAS 17009-4042, the 1.28 GHz map has resolved two radio sources that were previously reported as a single radio peak. Altogether, in each IRAS site, the junction of the filaments (i.e., massive clump) is investigated with the cluster of infrared-excess sources and the ongoing massive SF. This evidence is consistent with the “hub-filament” systems as proposed by Myers.
Dependence of the Spiral Arms Pitch Angle on Wavelength as a Test of the Density Wave Theory
Authors: Yu Si-Yue , Ho Luis C. 
Published: December 2018

Abstract
Large-scale galactic shocks, predicted by density wave theory, trigger star formation (SF-arms) downstream from the potential of the oldest stars (P-arms), resulting in a color jump from red to blue across spiral arms in the direction of rotation, while aging of these newly formed young stars induces the opposite but coexisting classic age gradient further downstream from the SF-arms. As the techniques for measuring pitch angle are intensity-weighted, they trace both the SF-arms and P-arms and are not sensitive to the classic age gradient. Consequently, the measured pitch angle of spiral arms should be systematically smaller in bluer bandpasses compared to redder bandpasses. We test these predictions using a comprehensive sample of high-quality optical (BVRI) images of bright, nearby spiral galaxies acquired as part of the Carnegie-Irvine Galaxy Survey, supplemented by Spitzer 3.6 μm data to probe evolved stars and Galaxy Evolution Explorer ultraviolet images to trace recent star formation. We apply one-dimensional and two-dimensional techniques to measure the pitch angle of spiral arms, paying close attention to adopt consistent procedures across the different bandpasses to minimize error and systematic bias. We find that the pitch angle of spiral arms decreases mildly but statistically significantly from the reddest to the bluest bandpass, demonstrating conclusively that young stars trace tighter spiral arms than old stars. Furthermore, the correlation between the pitch angle of blue and red bandpasses is nonlinear, such that the absolute value of pitch angle offset increases with increasing pitch angle. Both effects can be naturally explained in the context of the density wave theory for spiral structure.

Abstract
We present the first results of an Atacama Large Millimeter Array survey of the lower fine-structure line of atomic carbon [C i]

in far-infrared-selected galaxies on the main sequence at z ∼ 1.2 in the COSMOS field. We compare our sample with a comprehensive compilation of data available in the literature for local and high-redshift starbursting systems and quasars. We show that the [C i] (3
P

P

, similar to low-J CO transitions. We report a systematic variation of

/

as a function of the galaxy type, with the ratio being larger for main-sequence galaxies than for starbursts and submillimeter galaxies at fixed

. The

/

and

/

mass ratios are similar for main-sequence galaxies and for local and high-redshift starbursts within a 0.2 dex intrinsic scatter, suggesting that [C i] is a good tracer of molecular gas mass as CO and dust. We derive a fraction of

of the total carbon mass in the atomic neutral phase. Moreover, we estimate the neutral atomic carbon abundance, the fundamental ingredient to calibrate [C i] as a gas tracer, by comparing

and available gas masses from CO lines and dust emission. We find lower [C i] abundances in main-sequence galaxies than in starbursting systems and submillimeter galaxies as a consequence of the canonical α
CO and gas-to-dust conversion factors. This argues against the application to different galaxy populations of a universal standard [C i] abundance derived from highly biased samples.
The Pickup Ion-mediated Solar Wind

Published: December 2018

Abstract
The New Horizons Solar Wind Around Pluto (NH SWAP) instrument has provided the first direct observations of interstellar

and He

pickup ions (PUIs) at distances between ∼11.26 and 38 au in the solar wind. The observations demonstrate that the distant solar wind beyond the hydrogen ionization cavity is indeed mediated by PUIs. The creation of PUIs modifies the underlying low-frequency turbulence field responsible for their own scattering. The dissipation of these low-frequency fluctuations serves to heat the solar wind plasma, and accounts for the observed non-adiabatic solar wind temperature profile and a possible slow temperature increase beyond ∼30 au. We develop a very general theoretical model that incorporates PUIs, solar wind thermal plasma, the interplanetary magnetic field, and low-frequency turbulence to describe the evolution of the large-scale solar wind, PUIs, and turbulence from 1–84 au, the structure of the perpendicular heliospheric termination shock, and the transmission of turbulence into the inner heliosheath, extending the classical models of Holzer and Isenberg. A detailed comparison of the theoretical model solutions and observations derived from the Voyager 2 and NH SWAP data sets shows excellent agreement between the two for reasonable physical parameters.
Être mobile aujourd’hui : quelques acquis récents de la recherche en sciences sociales et enseignements pour la marche urbaine
Authors: Hubert Michel 
Published: December 2018

Ce texte traite de la problématique de la marche urbaine à l’aune de la recherche en sciences sociales sur la mobilité en général. Bon nombre d’auteurs en effet, sans nécessairement toujours traiter de la marche en tant que telle, développent des propos qui permettent de dégager des réflexions utiles pour cette problématique. Ainsi, l’histoire urbaine nous invite à appréhender l’évolution de la place de la marche dans la ville et à regarder les transformations urbanistiques, en particulier celles issues de la période moderniste, sous l’angle des barrières mises aux déambulations piétonnes par les grandes infrastructures de transport. Ensuite, à partir de la distinction entre mobilité et déplacement, peut-on interroger la marche urbaine dans sa capacité à nous donner accès, de manière sensible, à des contextes certes géographiquement proches, mais pourtant socialement très différents. Dans la même veine, on peut également se demander si la marche urbaine s’inscrit ou non dans l’injonction à être mobile qui caractérise les sociétés contemporaines et si elle concourt ou non à renforcer notre capital de mobilité. De son côté, la construction d’« attitudes spatio-temporelles » permet de mieux appréhender les logiques qui sous-tendent la pratique de la marche ou conduisent, au contraire, à l’éviter, à une époque où le temps de déplacement, grâce notamment aux nouvelles technologies de l’information et de la communication, tend à devenir un temps à part entière. Enfin, dans ce contexte, la signification de l’attente et de l’arrêt, en tant que pause dans une pérégrination, mérite d’être appréhendée dans sa totalité, ainsi que les dispositifs mis en place pour améliorer le confort de ces deux moments inséparables du mouvement.
Quand le pragmatisme est invité en architecture : une rencontre placée sous le signe de l’évidence
Authors: Lefebvre Pauline 
Published: December 2018

Prenant le thème du dossier au pied de la lettre, cet article fait l’histoire d’une rencontre donnée entre architecture et philosophie. La scène se situe à New York, en 2000, lorsque Joan Ockman prend l’initiative d’introduire la tradition philosophique américaine du Pragmatisme dans le champ de l’architecture. Elle met en place une série de dispositifs ambitieux afin que prenne cette rencontre inédite et risquée : un Reader réunissant des articles d’architectes et de philosophes pragmatistes autour de thèmes supposés communs, une assemblée transdisciplinaire réunie en panels ou en dialogue à l’occasion d’un workshop à Columbia University et d’une conférence au MoMA, et, finalement, la publication de certaines de ces contributions. L’échec relatif de cette série d’événements invite à interroger les conditions de réussite d’une telle rencontre. Pour ce faire, l’article propose d’abord de déplier les dispositifs mis en place avant d’entrer dans les arguments qu’ils ont permis de déployer. Le récit emprunte effectivement lui-même des méthodes et des critères pragmatistes : d’une part, l’artificialité de la rencontre est considérée comme une opportunité, d’autre part, son succès doit être mesuré à la lumière de ses conséquences. Finalement, ce sont des critères pragmatistes pour juger d’une bonne rencontre entre architecture et philosophie qui sont esquissés : cette scène et les discussions qui s’y manifestent amènent à envisager la reprise de pensées philosophiques par l’architecture comme relevant nécessairement d’une « trahison créative ».
Le programme « smart communities » au Japon. Nouveaux enjeux de pouvoir des ressources et des systèmes d’information urbains
Authors: Languillon-Aussel Raphaël 
Published: December 2018

Le Japon a mis en place en 2010, pour cinq ans, un programme national expérimental de démonstrateurs « smart » appelés « smart communities ». L’irruption du « smart » dans la fabrique urbaine japonaise ne relève toutefois pas d’une révolution soudaine, mais est le produit d’une lente transformation des rapports de pouvoir au sein des coalitions de croissance et des jeux d’acteurs impliqués dans l’aménagement urbain. Cet article formule l’hypothèse que cette transformation radicale des rapports de pouvoirs politiques, économiques et sociaux dont les « smart communities » résultent découle de la maîtrise des systèmes d’information urbains par les acteurs du numérique, et ce, bien en amont de leur centralisation informatique. Empreint d’économie politique, l’article s’ouvre sur une description des spécificités japonaises des « smart cities/smart communities » en termes technologiques, urbanistiques et politiques, puis y interroge la transformation des jeux d’acteurs et des rapports de pouvoir avant de se clore sur une réflexion critique des nouveaux modèles de société urbaine que proposent les acteurs du « smart » au Japon.
DE QUERVAIN'S SYNDROME: SURGICAL AND ANATOMICAL STUDIES OF THE FIBROOSSEOUS CANAL
Authors: Minamikawa Yoshitaka , Peimer Clayton A , Cox William L , Sherwin Frances S 
Published: December 2018

ABSTRACT
Anatomical variations of the first dorsal fibroosseous compartment were studied in 70 patients (38 women, 32 men) who underwent surgical release of the tendons. Seventy-one dissected forearms were also studied. De Quervain's tenosynovitis was the only diagnosis for two thirds of the patients. Nonoperative treatment for all of these patients failed. Forty-three patients (61%) had job-related symptoms. Recovery ranged from 3 to 36 months postoperatively (mean: 4.5 months). Multiple subcompartments were recorded in 47% of patients and in 75% of anatomic specimens. In 94% of the specimens, the abductor pollicis longus (APL) tendon had two to four süps, but in only two were there multiple extensor pollicis brevis (EPB) tendons. Surgeons must recognize that multiple APL tendon slips and two subcompartments are the rule, rather than the exception, in normal anatomy.
Olivia Ruiz. Les récits d’une ascension
Authors: Segré Gabriel 
Published: December 2018

Olivia Ruiz est une chanteuse issue de la téléréalité aujourd’hui reconnue comme artiste phare de la scène underground française. J’entreprends dans cet article l’analyse des récits (propos, témoignages, textes de chanson, biographies et autobiographies, documentaires) de cette ascension et de ces passages successifs (de la téléréalité à la scène underground, de l’anonymat au vedettariat, de « produit commercial » à « chanteuse à texte »). Je mets en lumière, à travers le cas particulier d’Olivia Ruiz, les multiples conflits définitionnels d’authenticité, les luttes de classement, les constructions de réputation, stratégies de distinction et conflits de légitimités, observables tant dans les actes que les discours, sur soi et sur les autres, et qui révèlent un espace de lutte, constitué d’une pluralité de territoires artistiques, hiérarchisés, valorisés, disqualifiés, structurés autour d’un pôle « commercial » (les majors, la télévision) et d’un pôle de l’« art pur », de la création, de l’avant-garde (ici de la chanson à texte, du rock underground).
Development of Inflammatory Hypoxia and Prevalence of Glycolytic Metabolism in Progressing Herpes Stromal Keratitis Lesions
Authors: Rao Pushpa , Suvas Susmit 
Published: December 2018

Abstract
Chronic inflammation in tissues often causes the development of hypoxia. Herpes stromal keratitis (HSK) is a corneal chronic inflammatory condition that develops in response to recurrent HSV-1 infection. In this study, we investigated the development of hypoxia, the expression of hypoxia-associated glycolytic genes in HSV-1 infected corneas, and the outcome of blocking hypoxia-inducible factor (HIF) dimerization on the severity of HSK. Our results showed the development of hypoxia, an elevated expression of hypoxia-associated glycolytic genes, and an increased level of lactate in corneas with progressing HSK lesions. The magnitude of hypoxia correlated with the extent of neutrophils infiltrating the infected corneas, and the depletion of neutrophils reduced the development of hypoxia in infected corneas. Additionally, in progressing HSK lesions, nuclear localization of HIF-2α protein was detected in corneal epithelial cells, whereas HIF-1α protein stabilization was observed in infiltrating immune cells. Administration of acriflavine drug to HSV-1–infected mice inhibited nuclear accumulation of HIF-1α and HIF-2α protein in immune cell types and epithelial cells, respectively, in infected corneas. As a result, a decreased influx of CD4 T cells and nongranulocytic myeloid cells, but an increased influx of neutrophils, was noted in developing HSK lesions. Interestingly, acriflavine treatment given during the clinical disease period decreased neovascularization but increased the opacity in HSV-1–infected corneas. Taken together, the results of our study lay the foundation to dissect the role of inflammatory hypoxia and hypoxia-associated genes in the pathogenesis of HSK.
