Abstract
Quantitative analysis of the interstellar heavy (oxygen and neon) atom fluxes obtained by the Interstellar Boundary Explorer (IBEX) suggests the existence of the secondary interstellar oxygen component. This component is formed near the heliopause due to charge exchange of interstellar oxygen ions with hydrogen atoms, as was predicted theoretically. A detailed quantitative analysis of the fluxes of interstellar heavy atoms is only possible with a model that takes into account both the filtration of primary and the production of secondary interstellar oxygen in the boundary region of the heliosphere as well as a detailed simulation of the motion of interstellar atoms inside the heliosphere. This simulation must take into account photoionization, charge exchange with the protons of the solar wind and solar gravitational attraction. This paper presents the results of modeling interstellar oxygen and neon atoms through the heliospheric interface and inside the heliosphere based on a three-dimensional kinetic-MHD model of the solar wind interaction with the local interstellar medium and a comparison of these results with the data obtained on the IBEX spacecraft.
Tunneling Rate Constants for H2CO+H on Amorphous Solid Water Surfaces
Authors: Song Lei , Kästner Johannes 
Published: November 2017

Abstract
Formaldehyde (H2CO) is one of the most abundant molecules observed in the icy mantle covering interstellar grains. Studying its evolution can contribute to our understanding of the formation of complex organic molecules in various interstellar environments. In this work, we investigated the hydrogenation reactions of H2CO yielding CH3O, CH2OH, and the hydrogen abstraction resulting in H2+HCO on an amorphous solid water (ASW) surface using a quantum mechanics/molecular mechanics (QM/MM) model. The binding energies of H2CO on the ASW surface vary broadly, from 1000 to 9370 K. No correlation was found between binding energies and activation energies of hydrogenation reactions. Combining instanton theory with QM/MM modeling, we calculated rate constants for the Langmuir–Hinshelwood and the Eley–Rideal mechanisms for the three product channels of H+H2CO surface reactions down to 59 K. We found that the channel producing CH2OH can be ignored, owing to its high activation barrier leading to significantly lower rates than the other two channels. The ASW surface influences the reactivity in favor of formation of CH3O (branching ratio ∼80%) and hinders the H2CO dissociation into H2+HCO. In addition, kinetic isotope effects are strong in all reaction channels and vary strongly between the channels. Finally, we provide fits of the rate constants to be used in astrochemical models.

Abstract
SN 2015J was discovered on 2015 April 27th and is classified as an SN IIn. At first, it appeared to be an orphan SN candidate, i.e., without any clear identification of its host galaxy. Here, we present an analysis of the observations carried out by the VLT 8 m class telescope with the FORS2 camera in the R band and the Magellan telescope (6.5 m) equipped with the IMACS Short-Camera (V and I filters) and the FourStar camera (Ks filter). We show that SN 2015J resides in what appears to be a very compact galaxy, establishing a relation between the SN event and its natural host. We also present and discuss archival and new X-ray data centered on SN 2015J. At the time of the supernova explosion, Swift/XRT observations were made and a weak X-ray source was detected at the location of SN 2015J. Almost one year later, the same source was unambiguously identified during serendipitous observations by Swift/XRT and XMM-Newton, clearly showing an enhancement of the 0.3–10 keV band flux by a factor

with respect to the initial state. Swift/XRT observations show that the source is still active in the X-rays at a level of

counts s−1. The unabsorbed X-ray luminosity derived from the XMM-Newton slew and SWIFT observations,

erg s−1, places SN 2015J among the brightest young supernovae in X-rays.
Determination of Dark Matter Halo Mass from Dynamics of Satellite Galaxies
Authors: Li Zhao-Zhou , Jing Y. P. , Qian Yong-Zhong , Yuan Zhen , Zhao Dong-Hai 
Published: November 2017

Abstract
We show that the mass of a dark matter halo can be inferred from the dynamical status of its satellite galaxies. Using nine dark matter simulations of halos like the Milky Way (MW), we find that the present-day substructures in each halo follow a characteristic distribution in the phase space of orbital binding energy and angular momentum, and that this distribution is similar from halo to halo, but has an intrinsic dependence on the halo formation history. We construct this distribution directly from the simulations for a specific halo and extend the result to halos of similar formation history but different masses by scaling. The mass of an observed halo can then be estimated by maximizing the likelihood in comparing the measured kinematic parameters of its satellite galaxies with these distributions. We test the validity and accuracy of this method with mock samples taken from the simulations. Using the positions, radial velocities, and proper motions of nine tracers and assuming observational uncertainties comparable to those of MW satellite galaxies, we find that the halo mass can be recovered to within

. The accuracy can be improved to within ∼25% if 30 tracers are used. However, the dependence of the phase-space distribution on the halo formation history sets a minimum uncertainty of

that cannot be reduced by using more tracers. We believe that this minimum uncertainty also applies to any mass determination for a halo when the phase-space information of other kinematic tracers is used.
Numerical Simulations of Turbulent Molecular Clouds Regulated by Radiation Feedback Forces. II. Radiation–Gas Interactions and Outflows
Authors: Raskutti Sudhir , Ostriker Eve C. , Skinner M. Aaron 
Published: November 2017

Abstract
Momentum deposition by radiation pressure from young, massive stars may help to destroy molecular clouds and unbind stellar clusters by driving large-scale outflows. We extend our previous numerical radiation hydrodynamic study of turbulent star-forming clouds to analyze the detailed interaction between non-ionizing UV radiation and the cloud material. Our simulations trace the evolution of gas and star particles through self-gravitating collapse, star formation, and cloud destruction via radiation-driven outflows. These models are idealized in that we include only radiation feedback and adopt an isothermal equation of state. Turbulence creates a structure of dense filaments and large holes through which radiation escapes, such that only ∼50% of the radiation is (cumulatively) absorbed by the end of star formation. The surface density distribution of gas by mass as seen by the central cluster is roughly lognormal with

, similar to the externally projected surface density distribution. This allows low surface density regions to be driven outwards to nearly 10 times their initial escape speed

. Although the velocity distribution of outflows is broadened by the lognormal surface density distribution, the overall efficiency of momentum injection to the gas cloud is reduced because much of the radiation escapes. The mean outflow velocity is approximately twice the escape speed from the initial cloud radius. Our results are also informative for understanding galactic-scale wind driving by radiation, in particular, the relationship between velocity and surface density for individual outflow structures and the resulting velocity and mass distributions arising from turbulent sources.
Laboratory Experiments on the Low-temperature Formation of Carbonaceous Grains in the ISM

Published: November 2017

Abstract
The life cycle of cosmic dust grains is far from being understood and the origin and evolution of interstellar medium (ISM) grains is still under debate. In the ISM, the cosmic dust destruction rate is faster than the production rate by stellar sources. However, observations of ISM refractory matter suggest that to maintain a steady amount of cosmic grains, some supplementary production mechanism takes place. In this context, we aimed to study possible reformation mechanisms of cosmic grains taking place at low temperature directly in the ISM. The low-temperature condensation of carbonaceous materials has been investigated in experiments mimicking the ISM conditions. Gas-phase carbonaceous precursors created by laser ablation of graphite were forced to accrete on cold substrates (T ≈ 10 K) representing surviving dust grains. The growing and evolution of the condensing carbonaceous precursors have been monitored by MIR and UV spectroscopy under a number of experimental scenarios. For the first time, the possibility to form ISM carbonaceous grains in situ is demonstrated. The condensation process is governed by carbon chains that first condense into small carbon clusters and finally into more stable carbonaceous materials, of which structural characteristics are comparable to the material formed in gas-phase condensation experiments at very high temperature. We also show that the so-formed fullerene-like carbonaceous material is transformed into a more ordered material under VUV processing. The cold condensation mechanisms discussed here can give fundamental clues to fully understand the balance between the timescale for dust injection, destruction, and reformation in the ISM.
Impact of Massive Neutrinos and Dark Radiation on the High-redshift Cosmic Web. I. Lyα Forest Observables
Authors: Rossi Graziano 
Published: November 2017

Abstract
With upcoming high-quality data from surveys such as the Extended Baryon Oscillation Spectroscopic Survey or the Dark Energy Spectroscopic Instrument, improving the theoretical modeling and gaining a deeper understanding of the effects of neutrinos and dark radiation on structure formation at small scales are necessary, to obtain robust constraints free from systematic biases. Using a novel suite of hydrodynamical simulations that incorporate dark matter, baryons, massive neutrinos, and dark radiation, we present a detailed study of their impact on Lyα forest observables. In particular, we accurately measure the tomographic evolution of the shape and amplitude of the small-scale matter and flux power spectra and search for unique signatures along with preferred scales where a neutrino mass detection may be feasible. We then investigate the thermal state of the intergalactic medium (IGM) through the temperature–density relation. Our findings suggest that at

the suppression on the matter power spectrum induced by

neutrinos can reach

at

when compared to a massless neutrino cosmology, and

if a massless sterile neutrino is included; surprisingly, we also find good agreement (

) with some analytic predictions. For the 1D flux power spectrum

, the highest response to free-streaming effects is achieved at

when

this k-limit falls in the Lyα forest regime, making the small-scale

an excellent probe for detecting neutrino and dark radiation imprints. Our results indicate that the IGM at

provides the best sensitivity to active and sterile neutrinos.
Survival of Advanced Stage High-Grade Serous Ovarian Cancer Patients in the Republic of Macedonia
Authors: Aluloski Igor , Tanturovski Mile 
Published: November 2017

AIM: The primary objective of the study was to evaluate the overall survival of women with advanced stage (Stage IIIA-IV) high-grade serous ovarian cancer in MacedoniaMATERIALS AND METHODS: The study was a cross-sectional medical record review of patients diagnosed with advanced stage HGSC. Patients were deemed eligible for inclusion if they were diagnosed with an advanced stage (Stage IIIA-IV) HGSC of the ovary, fallopian tube or peritoneum between 2009 and 2015. The data were analyzed in a descriptive fashion and summary statistics were provided, as appropriate. Survival was calculated using the Kaplan-Meier method.RESULTS: A total of 81 eligible patients were identified and included in the study. The average overall survival in the studied cohort was 46.59 months (95%CI = 39.11-54.06). Patients that were optimally debulked and patients that had a platinum-free interval larger than 12 months had significantly longer survival in the current series (p < 0.001).CONCLUSION: the average overall survival of advanced stage HGSC patients in the studied series was 46.59 months (95%CI = 39.11-54.06). Patients aged 65 years or younger tended to live approximately ten months longer than patients older than 65 years, but this difference was not statistically significant. There was no difference in HGSC survival in the groups of patients with grade 2 and grade 3 disease. However, optimal surgical debulking and platinum sensitivity were associated with significantly better overall survival.
First observations on the life cycle and mass eclosion events in a mantis fly (Family Mantispidae) in the subfamily Drepanicinae
Authors: Dorey James , Merritt David 
Published: November 2017

The Mantispidae are a distinctive group of Neuroptera known for the adults’ possession of raptorial forelegs. There are four recognised, extant subfamilies of Mantispidae: the Mantispinae, Symphrasinae, Calomantispinae and Drepanicinae. The life history and larval behaviour of the subfamily Mantispinae is best known: the immatures are spider egg predators. Among the three remaining subfamilies, larval Symphrasinae and Calomantispinae most likely predate on other small arthropods, while the immature life history of Drepanicinae, until now, remained completely unknown.
Here we provide observations of annual, near-synchronised, mass emergences of adults of the drepanicine, Ditaxis biseriata (Westwood), within a well-established Macadamia orchard in northern New South Wales, Australia. A female deposited fertile eggs, allowing this first report of egg batch and first instar morphology. The mass emergence of mobile pharate adults from the ground was observed in the same month in two consecutive years. The pharates climbed tree-trunks for a distance before undergoing eclosion. The newly-hatched first instar larvae are campodeiform and prognathous; a typical morphology among Mantispidae. After hatching, they drop to the ground and burrow into soil. They are unpigmented and appear to lack stemmata. Together, the observations infer that the immature component of the life cycle takes place underground in forested habitats. If this feature is common among the Drepanicinae, it might explain why so little is known of the biology of the immature stages.
Quelques réflexions sur le traitement terminographique unilingue de la métalangue grammaticale en français
Authors: Lerat Pierre 
Published: November 2017

Résumé Les termes sont ordinairement des dénominations d’objets ontologiques. Du fait du caractère métalinguistique de la terminologie grammaticale, les entités grammaticales ne sont pas des entités de sens commun, mais des conceptualisations spécifiques. La métalangue grammaticale dans une langue inclut des idiotismes (fr. présentatif ), des universaux (fr. terme d’adresse ), des faux amis (fr. gérondif ) et des emprunts (fr. masdar ). La terminographie de la grammaire a besoin de définitions, d’exemples canoniques, de termes associés et de sources philologiques, car sa validation n’est pas seulement épistémologique mais aussi sociale (universitaire, administrative, éditoriale).
Sur quelques emplois de la préposition to en co-texte nominal
Authors: Guimier Claude 
Published: November 2017

Résumé Cet article prend en compte un certain nombre d’emplois de la préposition to dans des configurations du type GN1 to GN2 . Dans la plupart de ces configurations, to alterne avec of , sans que cela entraîne nécessairement des variations marquées au niveau sémantique. L’examen de contextes privilégiés montre néanmoins le rôle spécial de to : cette préposition, virtualisante par nature, souligne le caractère non stabilisé du lien entre GN1 et GN2, à moins qu’elle ne soit plus spécialement orientée vers GN2, auquel cas c’est ce constituant qui est marqué comme non stabilisé.
Les « pseudo-adverbes » concessifs neporuec , neporquant , nequedent et l’adverbe toute(s)voie(s ) en ancien français
Authors: Bougy Catherine 
Published: November 2017

Résumé Très vivants en ancien français, les morphèmes neporuec , neporquant , nequedent et toutevoie(s) , tous traduits par « pourtant, cependant, toutefois », s’analysent différemment. Les « pseudos-adverbes » à ne initial, qui ne provoquent pas la postposition du sujet au verbe (contrairement à ce qui se produit pour les adverbes en ancien français) s’analysent comme la négation ne (« non ») + por huec ou por quant : « non, pas pour cela » et ne + que dent ( quid de inde ) : « non, rien de cela ». Ils constituent une phrase en eux-mêmes et permettent de porter un jugement sur le lien qui existe entre l’énoncé qui précède et celui qui suit : ils indiquent qu’il n’y a aucun rapport logique entre ces deux énoncés. Toutevoie(s ), qui prolonge le latin tota via « sur tout le chemin », est un véritable adverbe. Il a originellement exprimé la concomitance de deux procès, sans que l’un exclue l’autre. Dans certains contextes cependant, où les deux procès présentaient une opposition sémantique, toutevoie(s) s’est chargé d’un sémantisme clairement concessif. À partir du XIII e siècle, il a coexisté avec toutefois . Cet adverbe, inséré dans un paradigme morphologique fourni, s’est aisément substitué à toutevoies dont il est proche phonétiquement, ce d’autant plus que tout , employé seul, a, en ancien français, une valeur concessive que les locuteurs retrouvaient dans toutefois . À partir du XVI e siècle, les « pseudo-adverbes » et l’adverbe toutevoies ont disparu, au profit de toutefois qui a désormais une valeur concessive bien affirmée.
Concessives sans conjonction de subordination (à l’exception de wenn ) : syntagmes intégrés, connectés ou simplement juxtaposés. Le cas de l’allemand
Authors: Krause Maxi 
Published: November 2017

Résumé La présentation qui suit essaie de tracer de manière succincte les différents niveaux d’intégration ou de non intégration syntaxique des structures concessives (symbolisées par « C ») sans conjonction dans les structures non concessives (symbolisées par « NON-C ») auxquelles, sur le plan du sens, elles sont associées. L’intégration ou non intégration va de pair avec des structures spécifiques des C et la coopération d’éléments variés (essentiellement lexicaux et syntaxiques) qui, pris isolément, ne véhiculent en général aucune valeur concessive. C’est le fait de cette coopération nécessaire ainsi que des difficultés de décodage de ces structures qui justifie le choix ici opéré. La présentation essaie d’être accessible aux non germanistes, mais elle essaie aussi de donner une information condensée et immédiatement utilisable à ceux qui essaient de s’approprier la maîtrise de l’allemand. La délimitation entre concession et simple opposition n’est pas toujours aisée à faire et ressemble souvent à une lente transition de l’une vers l’autre, mais pour des raisons de format elle ne constitue pas un point de discussion de ce qui suit.
De l’occurrence à l’isotopie
Authors: Mayaffre Damon 
Published: November 2017

Résumé Cette contribution cherche à définir la co-occurrence comme une forme minimale du co(n)texte ; co(n)texte nécessaire à l’élaboration du sens et condition de l’interprétation. Constater que a et b sont co-occurrents n’est rien d’autre que contextualiser l’un par l’autre. Ainsi, nous montrons que l’enjeu du calcul des co-occurrences est essentiel pour la lexicométrie : c’est lui qui, par la contextualisation des formes qu’il propose, fait de la lexicométrie une pratique lexicologique ( versus lexicographique) et herméneutique (versus logico-formelle).
Paradoxes du multilinguisme
Authors: Slodzian Monique 
Published: November 2017

Résumé L’article porte sur les ambiguïtés de la notion de multilinguisme devenue centrale dans les technologies du Web et de ses usages. Lorsqu’il est conçu comme un obstacle à la communication, le multilinguisme assume une conception instrumentale des langues, présupposant une interface conceptuelle entre les langues, qui débouche sur l’interlinguisme. À l’opposé, conçu dans un cadre interprétatif, non fonctionnaliste, le multilinguisme est envisagé comme translinguisme, prenant en charge les changements induits par le passage d’un texte produit dans une langue / culture vers une autre langue / culture. Cette opposition sera illustrée et analysée dans le cadre de la traductologie. Les conclusions serviront à éclairer la problématique des corpus parallèles et des corpus comparables.
