Outer Architecture of Kepler-11: Constraints from Coplanarity
Authors: Jontof-Hutter Daniel , Weaver Brian P. , Ford Eric B. , Lissauer Jack J. , Fabrycky Daniel C. 
Published: April 2017

Abstract
The outer architectures of Kepler’s compact systems of multiple transiting planets remain poorly constrained, and few of these systems have lower bounds on the orbital distance of any massive outer planets. We infer a minimum orbital distance and upper limits on the inclination of a hypothetical Jovian-mass planet orbiting exterior to the six transiting planets at Kepler-11. Our constraints are derived from dynamical models together with observations provided by the Kepler mission. First, the lack of transit timing variations (TTV) in the outermost transiting planet Kepler-11 g imply that the system does not contain a Jovian-mass perturber within 2 au from the star. Second, we test under what initial conditions a Jovian-mass planet moderately inclined from the transiting planets would make their co-transiting configuration unlikely. The transiting planets are secularly coupled and exhibit small mutual inclinations over long timescales, although the outermost transiting planet, Kepler-11 g, is weakly coupled to the inner five. We rule out a Jovian-mass planet on a 3° inclination within 3.0 au, and higher inclinations out to farther orbital distances, unless an undetected planet exists orbiting in the dynamical gap between Kepler-11 f and Kepler-11 g. Our constraints depend little on whether we assume the six transiting planets of Kepler-11 were initially perfectly coplanar or whether a minimum initial mutual inclination between the transiting planets is adopted based on the measured impact parameters of the transiting planets.
Variation in GMC Association Properties across the Bars, Spiral Arms, Inter-arms, and Circumnuclear Region of M100 (NGC 4321) Extracted from ALMA Observations
Authors: Pan Hsi-An , Kuno Nario 
Published: April 2017

Abstract
We study the physical properties of giant molecular cloud associations (GMAs) in M100 (NGC 4321) using the ALMA Science Verification feathered (12 m+ACA) data in 12CO (1–0). To examine the environmental dependence of their properties, GMAs are classified based on their locations in various environments as circumnuclear ring (CNR), bar, spiral, and inter-arm GMAs. The CNR GMAs are massive and compact, while the inter-arm GMAs are diffuse, with low surface density. GMA mass and size are strongly correlated, as suggested by Larson. However, the diverse power-law index of the relation implies that the GMA properties are not uniform among the environments. The CNR and bar GMAs show higher velocity dispersion than those in other environments. We find little evidence for a correlation between GMA velocity dispersion and size, which indicates that the GMAs are in diverse dynamical states. Indeed, the virial parameter of the GMAs spans nearly two orders of magnitude. Only the spiral GMAs are generally self-gravitating. Star formation activity decreases in order over the CNR, spiral, bar, and inter-arm GMAs. The diverse GMA and star formation properties in different environments lead to variations in the Kennicutt–Schmidt relation. A combination of multiple mechanisms or gas phase change is necessary to explain the observed slopes. Comparisons of GMA properties acquired with the use of the 12 m array observations with those from the feathered data are also presented. The results show that the missing flux and extended emission cannot be neglected for the study of environmental dependence.
The Slowest Spinning X-Ray Pulsar in an Extragalactic Globular Cluster

Published: April 2017

Abstract
Neutron stars are thought to be born rapidly rotating and then exhibit a phase of rotation-powered pulsations as they slow down to 1–10 s periods. The significant population of millisecond pulsars observed in our Galaxy is explained by the recycling concept: during an epoch of accretion from a donor star in a binary system, the neutron star is spun up to millisecond periods. However, only a few pulsars are observed during this recycling process, with relatively high rotational frequencies. Here we report the detection of an X-ray pulsar with

in the globular cluster B091D in the Andromeda galaxy, the slowest pulsar ever found in a globular cluster. This bright (up to 30% of the Eddington luminosity) spinning-up pulsar, persistent over the 12 years of observations, must have started accreting less than 1 Myr ago and has not yet had time to accelerate to hundreds of Hertz. The neutron star in this unique wide binary with an orbital period

in a 12 Gyr old, metal-rich star cluster accretes from a low-mass, slightly evolved post-main-sequence companion. We argue that we are witnessing a binary formed at a relatively recent epoch by getting a ∼0.8

star in a dynamical interaction—a viable scenario in a massive, dense globular cluster like B091D with high global and specific stellar encounter rates. This intensively accreting non-recycled X-ray pulsar therefore provides a long-sought missing piece in the standard pulsar recycling picture.
Flavor-dependent Neutrino Angular Distribution in Core-collapse Supernovae
Authors: Tamborra Irene , Hüdepohl Lorenz , Raffelt Georg G. , Janka Hans-Thomas 
Published: April 2017

Abstract
According to recent studies, the collective flavor evolution of neutrinos in core-collapse supernovae depends strongly on the flavor-dependent angular distribution of the local neutrino radiation field, notably on the angular intensity of the electron lepton number carried by neutrinos. To facilitate further investigations of this subject, we study the energy and angle distributions of the neutrino radiation field computed with the Vertex neutrino-transport code for several spherically symmetric (1D) supernova simulations (of progenitor masses 11.2, 15, and 25 M
⊙) and explain how to extract this information from additional models of the Garching group. Beginning in the decoupling region (“neutrino sphere”), the distributions are more and more forward peaked in the radial direction with an angular spread that is largest for ν

e
, smaller for

, and smallest for ν

x
, where x = μ or τ. While the energy-integrated ν

e
minus

angle distribution has a dip in the forward direction, it does not turn negative in any of our investigated cases.

Published: April 2017

Abstract
In two earlier publications we analyzed 502 intervals of magnetic waves excited by newborn interstellar pickup protons that were observed by the Ulysses spacecraft. Due to the considerable effort required in identifying these events, we provide a list of the times for the 502 wave event intervals previously identified. In the process, we provide a brief description of how the waves were found and what their properties are. We also remind the reader of the conditions that permit the waves to reach observable levels and explain why the waves are not seen more often.

Background High genetic variability at the reverse transcriptase (RT) region of HBV could confer resistance to nucleoside/nucleotide analogues (NUCs). The aim of this study was to identify new RT amino acid (AA) substitutions related to NUC resistance. Methods HBV RT sequences of genotype C from 501 chronic hepatitis B (CHB) patients were analysed to identify potential RT substitutions related to NUC resistance. In vitro studies without and with NUCs were performed in a HepG2 cell line transfected by clones with RT harbouring wild-type or substituted AA(s) of interest. Results Among 261 NUC-treated CHB patients, we found a high detection rate of rtM204I/V substitution (30.7% [80/261]). We identified a new substitution of rtH55R, and its detection rate had a significantly increasing trend from 3.8% (9/240) in the untreated group to 7.2% (13/181) or 33.8% (27/80) in the treated group with rtM204 or with rtM204I/V substitutions ( P<0.0001). In vitro studies showed that rtH55R had a similar HBV DNA level compared to wild type. The rtH55R+rtM204I clone had a significantly better replication capacity than the rtM204I clone without NUCs ( P<0.05). The replication capacity of the rtM204I clone was found to significantly decrease under lamivudine treatment, but this was not found in the rtH55R+rtM204I clone. Conclusions We identified a new HBV RT substitution of rtH55R in genotype-C-infected CHB patients. It is frequently found in combination with rtM204I/V substitution under NUC treatment. In vitro studies suggest that it might play some replication compensatory role in rtM204I mutants under lamivudine treatment.
San Francisco, ville injuste ? La capitale du progressisme états-unien à l’épreuve de la croissance des inégalités
Authors: Lehman-Frisch Sonia 
Published: April 2017

Dans le contexte d’un débat intense sur l’augmentation des inégalités aux États-Unis, San Francisco a récemment été pointée du doigt comme l’une des grandes villes où elles sont les plus marquées. Cette dénonciation repose sur l’assimilation implicite de ces inégalités à une injustice insoutenable, alors même que les philosophes ont montré depuis longtemps qu’inégalités et injustice ne se confondent pas. Aussi semble-t-il important d’examiner avec attention la question des rapports entre inégalités et injustice dans le contexte des grandes villes. C’est ce que cet article propose de faire à partir du cas de la ville de San Francisco, en se concentrant spécifiquement sur la question des inégalités de revenus. Il explicite d’abord les enjeux d’une analyse de la dimension spatiale des inégalités de revenu au regard de la notion de justice. Il étudie ensuite le profond sentiment d’injustice nourri par ces inégalités, qui constitue à son tour le ferment d’importants mouvements de contestation. Enfin, face aux réactions de la société civile, il examine la manière dont les acteurs publics se situent au regard de cette question, dans une ville réputée pour être la capitale du progressisme aux États-Unis. Au bout du compte, à partir d’une analyse des liens entre inégalités (rendues visibles dans l’espace), ressentiment, mobilisations et politiques publiques, il s’agit de saisir si San Francisco, ville inégale, est aussi une ville injuste.
Le diagnostic en psychiatrie infanto-juvénile est-il possible et souhaitable ?
Authors: de Becker Emmanuel 
Published: April 2017

Question ancienne et pourtant toujours d’actualité, le diagnostic alimente débats et polémiques. La dernière version de l’échelle de classification du DSM n’a certainement pas apaisé ceux-ci. Dans le vaste champ de l’aide et des soins à l’égard de l’enfant et de l’adolescent, les questions liées au diagnostic transcendent souvent les aspects de prises en charge et de liens thérapeutiques ainsi que les multiples échanges entre professionnels concernés. Le diagnostic pédopsychiatrique est un processus dynamique, modifiable et momentané, les organisations pathologiques étant pour la plupart en transformation permanente. De manière spécifique et en fonction du processus développemental, la thématique du diagnostic en pédopsychiatrie renvoie plus à la question du risque évolutif qu’à la question d’un état pathologique en soi. S’appuyant sur une vignette clinique, l’article développe une réflexion sur ce que nous comprenons par diagnostic dans le domaine spécifique de la psychiatrie infanto-juvénile. Sont abordés les aspects généraux liés au diagnostic lui-même avant de souligner les places, fonctions, enjeux de l’enfant dans la société d’aujourd’hui. Puis, le thème même du diagnostic est discuté, en en montrant l’utilité et les risques. Ainsi, l’objectif vise à répondre à la question essentielle : le diagnostic en psychiatrie infanto-juvénile est-il possible et souhaitable ?
La mélancolie, envers de la thérapeutique
Authors: Glineur Cécile 
Published: April 2017

L’article soutient que le travail du psychologue orienté par les repères de la psychanalyse s’inscrit nécessairement hors de toute « furor sanandi », quand bien même sa pratique a lieu dans des institutions vouées au soin, voire à la guérison. À partir d’un cas clinique, l’auteur met en exergue que l’accompagnement clinique s’oriente des dires de l’usager et du repérage d’une logique subjective qui lui est propre, non d’une volonté ni d’un désir thérapeutique posé a priori.
Grec logos : premières approches philosophiques et grammaticales de l’énoncé
Authors: Ildefonse Frédérique , Lallot Jean 
Published: April 2017

Le grec logos , que l’on peut traduire, entre autres, par « énoncé », peut s’appliquer à tout ensemble langagier signifiant analysable en constituants eux-mêmes signifiants – en fait, des mots que la tradition définira comme « parties du logos ». Platon déclare forme « première et minimale » du logos une séquence comme « l’homme apprend », décrite comme l’entrelacement d’un nom (onoma) et d’un verbe (rhêma) . Cet objet complexe, soumis à une syntaxe, a la propriété sui generis de dire quelque chose, de vrai ou de faux, sur le monde : Aristote le nommera logos apophantikos « énoncé déclaratif » – et c’est en prenant appui sur ce socle que la tradition logico-grammaticale grecque mettra en évidence la diversité des énoncés autres que déclaratifs simples. Les Stoïciens ont apporté ici une contribution décisive dont on entrevoit la fécondité dans l’œuvre conservée d’Apollonius Dyscole.
Points de vue sur l’énoncé et typologies propositionnelles dans la grammaire générale française (XVII e -XVIII e siècles)
Authors: Raby Valérie 
Published: April 2017

La grammaire générale française ( xvii e - xviii e siècles) a fait de l’énoncé, sous l’espèce propositionnelle, le niveau d’analyse pertinent pour tenter de fonder une théorie générale du langage et des langues. Le renouvellement des traditions d’analyse de l’énoncé passe par une représentation de la proposition comme objet pluridimensionnel, susceptible de plusieurs « points de vue », dont rendent compte les nombreuses typologies propositionnelles élaborées par les grammaires générales du xviii e siècle. Cette étude vise à éclairer les principes et conditions de développement du motif interprétatif des points de vue sur la proposition ou la phrase, depuis sa première formulation dans la grammaire et la logique de Port-Royal jusqu’au début du xix e siècle.
Le pronom ON dans l’interaction en face à face : une ressource de (dé)contextualisation
Authors: Jacquin Jérôme 
Published: April 2017

L’article revient sur le pronom ON en réinterrogeant la capacité qu’on lui octroie d’anonymiser le référent. Cette possibilité étant tout à fait avérée, comme en témoigne la phrase précédente, elle a eu tendance à monopoliser les recherches et à contribuer à consolider une démarche substitutive dans le traitement des emplois de ON : si ON anonymise, c’est parce qu’une autre forme dont le sémantisme est plus précis aurait convenu pour opérer une référence identique. L’article discute cette approche substitutive et, au travers de l’analyse énonciative et multimodale d’extraits de débats publics et télévisés, montre que ON peut permettre au locuteur de maintenir son énoncé à un certain niveau de généralité ( i.e. orientation vers la décontextualisation), mais sans pour autant empêcher le pointage simultané, par le biais d’autres ressources sémiotiques, d’un ou de plusieurs exemplaire(s) de la classe ainsi parcourue ( i.e. orientation vers la contextualisation).

Abstract
African green monkeys (AGMs) are a natural host of SIV that do not develop simian AIDS. Adult AGMs naturally have low numbers of CD4+ T cells and a large population of MHC class II–restricted CD8αα T cells that are generated through CD4 downregulation in CD4+ T cells. In this article, we study the functional profiles and SIV infection status in vivo of CD4+ T cells, CD8αα T cells, and CD8αβ T cells in lymph nodes, peripheral blood, and bronchoalveolar lavage fluid of AGMs and rhesus macaques (in which CD4 downregulation is not observed). We show that, although CD8αα T cells in AGMs maintain functions associated with CD4+ T cells (including Th follicular functionality in lymphoid tissues and Th2 responses in bronchoalveolar lavage fluid), they also accumulate functions normally attributed to canonical CD8+ T cells. These hyperfunctional CD8αα T cells are found to circulate peripherally, as well as reside within the lymphoid tissue. Due to their unique combination of CD4 and CD8 T cell effector functions, these CD4− CD8αα T cells are likely able to serve as an immunophenotype capable of Th1, follicular Th, and CTL functionalities, yet they are unable to be infected by SIV. These data demonstrate the ambiguity of CD4/CD8 expression in dictating the functional capacities of T cells and suggest that accumulation of hyperfunctional CD8αα T cells in AGMs may lead to tissue-specific antiviral immune responses in lymphoid follicles that limit SIV replication in this particular anatomical niche.
Lingual Foramina and Canals of the Mandible: Anatomic Variations in a Lebanese Population
Authors: Aoun Georges , Nasseh Ibrahim , Sokhn Sayde , Rifai Mohamad 
Published: April 2017

Objective:
The aim of this study was to evaluate the mandibular lingual foramina (LF) and canals and their anatomic variations using cone-beam computed tomography (CBCT) technology in a Lebanese population.

Materials and Methods:
In this study, we analyzed CBCT images of 90 adult Lebanese patients (41 males and 49 females). We assessed the number and location of the LF. In additional, we measured: (a) The distance from both the alveolar crest and the inferior border of the mandible to the LF and (b) the length of the lingual canals (LCs). The data obtained was analyzed statistically using Shapiro–Wilk normality test, t-test, Chi-square, and Fisher's exact tests. Statistical significance was set at 0.05.

Results:
In our sample, the LF and canals were present in 93.33% of the CBCT analyzed, and the majority (76.64%) was located above the genial tubercles. The distance from the foramen of the superior and the inferior LCs to the alveolar crest was 16.24 ± 2.82 mm and 25.49 ± 2.43 mm, respectively. The distance from the foramen of the superior canal to the inferior border of the mandible was 14 ± 2.32 mm. The mean length of the superior canal was 5.81 ± 1.6 mm and 4.25 ± 1.2 mm for the inferior one. There were no gender-related differences in the anatomic characteristics of the LF and canals except for the distance measured from the superior canal foramina to the alveolar crest where the measurement was significantly greater in males compared to females. Neither the number of canals nor the positions of the foramina were different between males and females.

Conclusion:
Within the limits of this study, we concluded that in our sample of Lebanese adults, there was substantial variability in the LF and canals anatomy and location.
Remarks on Hopf Images and Quantum Permutation Groups
Authors: Józiak Paweł 
Published: April 2017

AbstractMotivated by a question of A. Skalski and P. M. Sołtan (2016) about inner faithfulness of S. Curran’s map of extending a quantum increasing sequence to a quantum permutation, we revisit the results and techniques of T. Banica and J. Bichon (2009) and study some group-theoretic properties of the quantum permutation group on points. This enables us not only to answer the aforementioned question in the positive for the case where n = 4, k = z, but also to classify the automorphisms of , describe all the embeddings O−1(2) ⊂ and show that all the copies of O−1(2) ⊂ are conjugate. We then use these results to show that the converse to the criterion we applied to answer the aforementioned question is not valid.

Abstract. To improve our knowledge of urban meteorology, including those processes applicable to high-resolution meteorological models in the Seoul Metropolitan Area (SMA), the Weather Information Service Engine (WISE) Urban Meteorological Observation System (UMS-Seoul) has been designed and installed. The UMS-Seoul incorporates 14 surface energy balance (EB) systems, 7 surface-based three-dimensional (3-D) meteorological observation systems and applied meteorological (AP) observation systems, and the existing surface-based meteorological observation network. The EB system consists of a radiation balance system, sonic anemometers, infrared CO2/H2O gas analyzers, and many sensors measuring the wind speed and direction, temperature and humidity, precipitation, and air pressure. The EB-produced radiation, meteorological, and turbulence data will be used to quantify the surface EB according to land use and to improve the boundary-layer and surface processes in meteorological models. The 3-D system, composed of a wind lidar, microwave radiometer, aerosol lidar, or ceilometer, produces the cloud height, vertical profiles of backscatter by aerosols, wind speed and direction, temperature, humidity, and liquid water content. It will be used for high-resolution reanalysis data based on observations and for the improvement of the boundary-layer, radiation, and microphysics processes in meteorological models. The AP system includes road weather information, mosquito activity, water quality, and agrometeorological observation instruments. The standardized metadata for networks and stations are documented and renewed periodically to provide a detailed observation environment. The UMS-Seoul data are designed to support real-time acquisition and display and automatically quality check within 10 min from observation. After the quality check, data can be distributed to relevant potential users such as researchers and policy makers. Finally, two case studies demonstrate that the observed data have a great potential to help to understand the boundary-layer structures more deeply, improve the performance of high-resolution meteorological models, and provide useful information customized based on the user demands in the SMA.
