Published: June 2017

Abstract
We provide the first observational constraints on the sizes of the faintest galaxies lensed by the Hubble Frontier Fields (HFF) clusters. Ionizing radiation from faint galaxies likely drives cosmic reionization, and the HFF initiative provides a key opportunity to find such galaxies. However, we cannot assess their ionizing emissivity without a robust measurement of their sizes, since this is key to quantifying both their prevalence and the faint-end slope to the UV luminosity function. Here we provide the first size constraints with two new techniques. The first utilizes the fact that the detectability of highly magnified galaxies as a function of shear is very dependent on a galaxy’s size. Only the most compact galaxies remain detectable in high-shear regions (versus a larger detectable size range for low shear), a phenomenon we quantify using simulations. Remarkably, however, no correlation is found between the surface density of faint galaxies and the predicted shear, using 87 high-magnification (

–100)

–8 galaxies seen behind the first four HFF clusters. This can only be the case if faint (

mag) galaxies have significantly smaller sizes than more luminous galaxies, i.e.,

mas or 160–240 pc. As a second size probe, we rotate and stack 26 faint high-magnification sources along the major shear axis. Less elongation is found even for objects with an intrinsic half-light radius of 10 mas. Together, these results indicate that extremely faint

–8 galaxies have near point-source profiles (half-light radii <30 mas and perhaps 5–10 mas). These results suggest smaller completeness corrections and hence shallower faint-end slopes for the

–8 LFs than derived in some recent studies (by

–0.3).

Abstract
We present the first catalog of TeV gamma-ray sources realized with data from the newly completed High Altitude Water Cherenkov Observatory (HAWC). It is the most sensitive wide field-of-view TeV telescope currently in operation, with a one-year survey sensitivity of ∼5%–10% of the flux of the Crab Nebula. With an instantaneous field of view >1.5 sr and >90% duty cycle, it continuously surveys and monitors the sky for gamma-ray energies between hundreds of GeV and tens of TeV. HAWC is located in Mexico, at a latitude of 19° N, and was completed in 2015 March. Here, we present the 2HWC catalog, which is the result of the first source search performed with the complete HAWC detector. Realized with 507 days of data, it represents the most sensitive TeV survey to date for such a large fraction of the sky. A total of 39 sources were detected, with an expected number of false detections of 0.5 due to background fluctuation. Out of these sources, 19 are new sources that are not associated with previously known TeV sources (association criteria: <0.°5 away). The source list, including the position measurement, spectrum measurement, and uncertainties, is reported, then each source is briefly discussed. Of the 2HWC associated sources, 10 are reported in TeVCat as PWN or SNR: 2 as blazars and the remaining eight as unidentified.
A Simple and Accurate Network for Hydrogen and Carbon Chemistry in the Interstellar Medium
Authors: Gong Munan , Ostriker Eve C. , Wolfire Mark G. 
Published: June 2017

Abstract
Chemistry plays an important role in the interstellar medium (ISM), regulating the heating and cooling of the gas and determining abundances of molecular species that trace gas properties in observations. Although solving the time-dependent equations is necessary for accurate abundances and temperature in the dynamic ISM, a full chemical network is too computationally expensive to incorporate into numerical simulations. In this paper, we propose a new simplified chemical network for hydrogen and carbon chemistry in the atomic and molecular ISM. We compare results from our chemical network in detail with results from a full photodissociation region (PDR) code, and also with the Nelson & Langer (NL99) network previously adopted in the simulation literature. We show that our chemical network gives similar results to the PDR code in the equilibrium abundances of all species over a wide range of densities, temperature, and metallicities, whereas the NL99 network shows significant disagreement. Applying our network to 1D models, we find that the CO-dominated regime delimits the coldest gas and that the corresponding temperature tracks the cosmic-ray ionization rate in molecular clouds. We provide a simple fit for the locus of CO-dominated regions as a function of gas density and column. We also compare with observations of diffuse and translucent clouds. We find that the CO,

, and

abundances are consistent with equilibrium predictions for densities

, but the predicted equilibrium C abundance is higher than that seen in observations, signaling the potential importance of non-equilibrium/dynamical effects.
High-resolution Velocity Fields of Low-mass Disk Galaxies. I. CO Observations

Published: June 2017

Abstract
This paper is the first in a series whose aim is to examine the relative distributions of dark and baryonic matter as a function of star formation history in a representative sample of low-mass disk galaxies. In this paper, we present high-resolution 12CO(

) interferometry for a sample of 26 nearby dwarf galaxies that were obtained from the Combined Array for Research in Millimeter-wave Astronomy (CARMA). Among these 26 galaxies, 14 have good CO detections, including 6 galaxies previously detected in single-dish CO measurements and 8 newly detected ones. We find a linear correlation between the CO flux and the mid- and far-IR flux from the WISE and IRAS catalogs. Compared to the far-IR flux, the mid-IR flux may be a better indication of whether a galaxy contains sufficient CO for detection at the level of instrument sensitivity of CARMA. This correlation might prove to be useful in future studies to help choosing other CO targets for observation. The median molecular mass (including helium) of our galaxies is

, which is consistent with past observations for dwarf galaxies. The molecular content is weakly correlated with the dynamical mass, r-band luminosity and size of the galaxies. The median ratios of molecular mass versus dynamical mass and molecular mass versus r-band luminosity are

and

, respectively, which are also consistent with past observations for dwarf galaxies.
Le Figaro de Pierre Brisson sous Vichy : journal libéral et légaliste
Authors: Jian Philippe 
Published: June 2017

L’historiographie de la presse des années noires retient le combat mené par Le	Figaro replié en zone libre contre la Censure et la forte opposition de son supplément littéraire au moralisme ambiant. L’approche nous semble cependant bien incomplète tant elle néglige la ligne éditoriale du journal de Pierre Brisson qui illustre d’une part cette utopie qu’a représentée la Révolution nationale auprès des libéraux conservateurs nostalgiques du poincarisme et d’autre part, la foi inébranlable en la revanche dans le seul cadre de la continuité de l’État que représente le maréchal Pétain.
Travailleurs détachés, travailleurs délaissés
Authors: Isidro Lola 
Published: June 2017

Depuis plus de 15 ans, le nombre de travailleurs détachés pour l’exécution d’une prestation de service au sein de l’Union européenne ne cesse de croître, notamment dans le bâtiment et le travail temporaire. Pourtant, le travail détaché est attaqué de toutes parts au nom de la défense du marché national de l’emploi, mais aussi de la protection des travailleurs. Car il pose clairement la question de la législation applicable à ces travailleurs et, ce faisant, du dumping social dans une Europe où les libertés économiques l’emportent sur les droits sociaux.

On connaît le plombier polonais. Mais le connait-on vraiment ? Car, plus qu’une véritable nouvelle figure de l’immigration, ledit plombier est un mythe douteux aux relents xénophobes créé par le triste Philippe Val 1 , un mythe qui a largement alimenté le débat sur le projet de directive de « libéralisation » des services (dite « Bolkestein »), finalement rejeté. Dix ans plus tard, la prestation de services internationale est une réalité tangible, mais continue de faire débat (électoral). Plus que d’éviers bouchés et de tuyaux qui fuient, il est question ici de fruits et légumes, d’ouvriers latinos et de boîtes d’intérim espagnoles.

Meditation's Effect on Attentional Efficiency, Stress, and Mindfulness Characteristics of Nursing Students
Authors: Burger Kathleen G. , Lockhart Joan Such 
Published: June 2017

Background:
Strengthening attention-regulation efficiency of nurse graduates is important to the quality and safety of nursing practice in increasingly complex and cognitively distracting workplaces. Neuroscientific evidence suggests that regular practice of focused meditation can enhance attentional skills. This study explored meditation as an educational strategy for enhancing nursing students' attentional efficiency.

Method:
A randomized-control trial with 52 prelicensure nursing students examined differences between those who meditated and those who did not on measurements of alerting, orienting, and executive attention. Stress and mindfulness were also explored.

Results:

Meditation demonstrated moderate strength for enhancing executive attention,
F
= 4.26 (1, 49),
n
2
= .080,
p
= .044. Additional outcomes specific to the meditation group were reduced stress and increased mindfulness,
F
= 7.16 (2, 47),
n
2
= .234,
p
= .002.

Conclusion:

Results support the consideration of meditation training as a strategy for enhancing nursing students' attentional efficiency and other self-regulatory skills necessary for safe nursing practice. [

Territoire, web et droits de l’homme : la Toile s’étiole, l’étoile décline
Authors: Desrumaux Nicolas 
Published: June 2017

Deux mouvements antagonistes traduisent les relations entre Internet, le territoire et les droits de l’homme. Le premier est que les droits de l’homme et Internet partagent la même aspiration universaliste de transcendance des frontières, de telle sorte qu’ils tendent à s’affranchir de tout ancrage national. Le second est que les États tendent à investir de plus en plus le cyberespace, assujettissant celui-ci à leurs lois nationales, quitte à s’immiscer dans les droits fondamentaux de leurs utilisateurs. Le premier affirme le caractère a-territorial du droit, le second suppose une assise légale aux échanges dématérialisés. Résoudre cet antagonisme suppose de redéfinir l’application territoriale du droit, de revoir le rôle d’Internet dans la promotion et la dissémination des droits de l’homme, et enfin de réorienter les fonctions accomplies par les détenteurs d’une autorité et de pouvoirs de coercition. Ce double mouvement est d’autant plus intéressant à analyser à l’aune des « Printemps arabes » que ces derniers ont vu la revendication de nouveaux droits, l’affermissement de nouveaux pouvoirs politiques et la conquête de nouveaux espaces numériques.
Beyond revenge?: Responsible Bible reading practices in a Traumatized Land
Authors: Claassens Juliana M. 
Published: June 2017

In this article, I argue that revenge fantasies such as those found in the Oracles Against the Nations (OAN) in Jeremiah 45–51 underscore the necessity for responsible Bible reading practices. I argue that to protect us from our own worst selves, the very human tendency to resort to revenge that inevitably leads to violence, one needs to read these biblical texts in terms of contemporary hermeneutical approaches that may play some role to bring an end to violence. A first such approach that serves as an important tool to help us understand these revenge fantasies as found in the OAN is the relatively new field of inquiry of trauma hermeneutics that is particularly helpful in order to mitigate the violent aspects of these revenge fantasies. Moreover, I propose that recent approaches such as feminist and postcolonial biblical interpretation are also vital for nurturing ethical, just communities that actively pursue justice.

Our research was focused to identify the Botrytis, Fusarium and Rhizopus species from grapes of the Slovak origin. A further goal of the project was to characterized toxinogenic potential of chosen strains of species Fusarium. 50 samples of grapes, harvested in years 2011, 2012 and 2013 from various wine-growing regions were analyzed in this study. For the isolation of species the of direct plating method was used: a) surface-sterilized berries (using 1% freshly pre-pared chlorine) b) berries and c) damaged berries on DRBC (Dichloran Rose Bengal Chloramphenicol agar). For each analysis were used 50 berries (or all damaged berries from sample). The cultivation was carried at 25 ±1°C, for 5 to 7 days in dark. After incubation, the colonies of Botrytis, Fusarium and Rhizopus were transferred to identification media and after incubation strains were identified to species level. Thirteen species of fusaria (F. acuminatum, F. avenaceum, F. culmorum, F. equiseti, F. graminearum, F. oxysporum, F. proliferatum, F. semitectum, F. solani, F. sporotrichioides, F. subglutinans F. tricinctum and F. verticilioides) were identified. Frequency of fusaria isolation was 92 %. Botrytis cinerea was determined from 86% samples and Rhizopus from 94%. Chosen strains of species of genus Fusarium were able to produce following mycotoxins: deoxynivalenol, T-2 toxin, HT-2 toxin and diacetoxyscirpenol in in vitro conditions as determinated by thin-layer chromatography. Thirty-two (68%) of tested isolates of Fusarium species were able to produce at least one mycotoxin.

AbstractIntroduction: We evaluated the diagnostic accuracy of HIV testing algorithms at six programmes in five sub‐Saharan African countries.Methods: In this prospective multisite diagnostic evaluation study (Conakry, Guinea; Kitgum, Uganda; Arua, Uganda; Homa Bay, Kenya; Doula, Cameroun and Baraka, Democratic Republic of Congo), samples from clients (greater than equal to five years of age) testing for HIV were collected and compared to a state‐of‐the‐art algorithm from the AIDS reference laboratory at the Institute of Tropical Medicine, Belgium. The reference algorithm consisted of an enzyme‐linked immuno‐sorbent assay, a line‐immunoassay, a single antigen‐enzyme immunoassay and a DNA polymerase chain reaction test.Results: Between August 2011 and January 2015, over 14,000 clients were tested for HIV at 6 HIV counselling and testing sites. Of those, 2786 (median age: 30; 38.1% males) were included in the study. Sensitivity of the testing algorithms ranged from 89.5% in Arua to 100% in Douala and Conakry, while specificity ranged from 98.3% in Doula to 100% in Conakry. Overall, 24 (0.9%) clients, and as many as 8 per site (1.7%), were misdiagnosed, with 16 false‐positive and 8 false‐negative results. Six false‐negative specimens were retested with the on‐site algorithm on the same sample and were found to be positive. Conversely, 13 false‐positive specimens were retested: 8 remained false‐positive with the on‐site algorithm.Conclusions: The performance of algorithms at several sites failed to meet expectations and thresholds set by the World Health Organization, with unacceptably high rates of false results. Alongside the careful selection of rapid diagnostic tests and the validation of algorithms, strictly observing correct procedures can reduce the risk of false results. In the meantime, to identify false‐positive diagnoses at initial testing, patients should be retested upon initiating antiretroviral therapy.
How variable is the number of triggered aftershocks?
Authors: Marsan D. , Helmstetter A. 
Published: June 2017

AbstractAftershock activity depends at first order on the main shock magnitude but also shows important fluctuations between shocks of equal magnitude. We here investigate these fluctuations, by quantifying them and by relating them to the main shock stress drop and other variables, for southern California earthquakes. A method is proposed in order to only count directly triggered aftershocks, rather than secondary aftershocks (i.e., triggered by previous aftershocks), and to only quantify fluctuations going beyond the natural Poisson variability. Testing of the method subjected to various model errors allows to quantify its robustness. It is found that these fluctuations follow a distribution that is well fitted by a lognormal distribution, with a coefficient of variation of about 1.0 to 1.1. A simple model is proposed to relate this observed dependence to main shock stress drop variability.
Ultrasonic monitoring of spontaneous imbibition experiments: Precursory moisture diffusion effects ahead of water front

Published: June 2017

AbstractFluid substitution processes have been investigated in the laboratory on 14 carbonate and siliciclastic reservoir rock analogues through spontaneous imbibition experiments on vertical cylindrical specimens with simultaneous ultrasonic monitoring and imaging. The motivation of our study was to identify the seismic attributes of fluid substitution in reservoir rocks and to link them to physical processes. It is shown that (i) the P wave velocity either decreases or increases when the capillary front reaches the Fresnel clearance zone, (ii) the P wave amplitude is systematically impacted earlier than the velocity is, (iii) this precursory amplitude decrease occurs when the imbibition front is located outside of the Fresnel zone, and (iv) the relative variation of the P wave amplitude is always much larger than that of the P wave velocity. These results suggest that moisture diffuses into the pore space ahead of the water front. This postulate is further supported by a quantitative analysis of the time evolution of the observed P wave amplitudes. In a sense, P wave amplitude acts as a precursor of the arrival of the capillary front. This phenomenon is used to estimate the effective diffusivity of moisture in the tested rocks. The effective moisture diffusivity estimated from the ultrasonic data is strongly correlated with permeability: a power law with exponent 0.96 predicts permeability from ultrasonic monitoring within a factor 3 without noticeable bias. When the effective diffusivity is high, moisture diffusion affects ultrasonic P wave attributes even before the imbibition starts and impacts the P wave reflectivity as evidenced by the variations recorded in the waveform coda.
Observations and fine‐scale model simulations of gravity waves over Davis, East Antarctica (69°S, 78°E)
Authors: Alexander S. P. , Orr A. , Webster S. , Murphy D. J. 
Published: June 2017

AbstractLarge vertical velocities were observed throughout the troposphere at Davis, East Antarctica, on 18 February 2014 by a VHF wind‐profiling radar. Simulations using the Met Office Unified Model at 2.2, 0.5, and 0.1 km horizontal grid spacing were able to broadly capture the location, timing, and magnitude of the observed velocities, as well as reveal that they are due to small‐scale orographic gravity waves resulting from the interaction between the coastal topography and strong easterly winds associated with a synoptic‐scale cyclone situated to the north. The simulations indicated that the gravity waves are responsible for (i) temperature fluctuations which coincided with satellite‐observed cloud variations in the vicinity of Davis, suggesting that they have a crucial role in the formation of cirrus clouds, and (ii) large vertical momentum fluxes in the troposphere. The waves are prevented from propagating into the stratosphere by the background winds turning from near‐surface easterlies to lower stratospheric northerlies. As well as illuminating and quantifying the role that weather systems have in producing orographic gravity waves along the East Antarctic coastline, studies such as this should be exploited to improve the representation of key localized atmospheric processes in global climate models.
Awntyrs off Arthure at the Terne Wathelyn
Authors: Schiff Randy P. 
Published: June 2017

Abstract

The Awntyrs off Arthure
is an anonymous, late‐medieval, alliterative romance composed in the 13‐line stanza, surviving in varying forms in four manuscripts. The poem first narrates an encounter with the ghost of Guinevere's mother, who both urges Guinevere to seek salvation and condemns the Arthurian militarism practiced by Gawain, and then portrays Galeron of Galloway's fateful effort to reclaim his lands by dueling Gawain before Arthur's court. With its linkage of spiritual condemnation and militarist expansionism, the
Awntyrs
directs itself to the culture of an unstable borderlands.
