Abstract
We present ALMA CO (2–1) detections in 11 gas-rich cluster galaxies at z ∼ 1.6, constituting the largest sample of molecular gas measurements in z > 1.5 clusters to date. The observations span three galaxy clusters, derived from the Spitzer Adaptation of the Red-sequence Cluster Survey. We augment the >5σ detections of the CO (2–1) fluxes with multi-band photometry, yielding stellar masses and infrared-derived star formation rates, to place some of the first constraints on molecular gas properties in z ∼ 1.6 cluster environments. We measure sizable gas reservoirs of 0.5–2 × 1011
M
☉ in these objects, with high gas fractions (f
gas) and long depletion timescales (τ), averaging 62% and 1.4 Gyr, respectively. We compare our cluster galaxies to the scaling relations of the coeval field, in the context of how gas fractions and depletion timescales vary with respect to the star-forming main sequence. We find that our cluster galaxies lie systematically off the field scaling relations at z = 1.6 toward enhanced gas fractions, at a level of ∼4σ, but have consistent depletion timescales. Exploiting CO detections in lower-redshift clusters from the literature, we investigate the evolution of the gas fraction in cluster galaxies, finding it to mimic the strong rise with redshift in the field. We emphasize the utility of detecting abundant gas-rich galaxies in high-redshift clusters, deeming them as crucial laboratories for future statistical studies.

Abstract
We present the first results from the ongoing Lyman Alpha Galaxies in the Epoch of Reionization (LAGER) project, which is the largest narrowband survey for z ∼ 7 galaxies to date. Using a specially built narrowband filter NB964 for the superb large-area Dark Energy Camera (DECam) on the NOAO/CTIO 4 m Blanco telescope, LAGER has collected 34 hr NB964 narrowband imaging data in the 3 deg2 COSMOS field. We have identified 23 Lyα Emitter candidates at z = 6.9 in the central 2-deg2 region, where DECam and public COSMOS multi-band images exist. The resulting luminosity function (LF) can be described as a Schechter function modified by a significant excess at the bright end (four galaxies with L
Lyα
∼ 1043.4±0.2 erg s−1). The number density at L
Lyα
∼ 1043.4±0.2 erg s−1 is little changed from z = 6.6, while at fainter L
Lyα
it is substantially reduced. Overall, we see a fourfold reduction in Lyα luminosity density from z = 5.7 to z = 6.9. Combined with a more modest evolution of the continuum UV luminosity density, this suggests a factor of ∼3 suppression of Lyα by radiative transfer through the z ∼ 7 intergalactic medium (IGM). It indicates an IGM neutral fraction of x
H i
∼ 0.4–0.6 (assuming Lyα velocity offsets of 100–200 km s−1). The changing shape of the Lyα LF between z ≲ 6.6 and z = 6.9 supports the hypothesis of ionized bubbles in a patchy reionization at z ∼ 7.
Monstres sauvages ou hybrides psychopompes ?
Authors: Petit Thierry 
Published: June 2017

Dans un ouvrage récent ( Monster in der frühgriechischen Kunst: Die Überwindung des Unfassbaren , 2015), Lorenz Winckler-Horaček étudie la figure des « monstres » dans l’art figuré de la Grèce à l’époque archaïque, spécialement à partir de la peinture de vases corinthienne, dont il prend en compte toute la production. Il entend démontrer que ces hybrides sont les symboles du « monde du “dehors” » ou monde animal. L’analyse échoue cependant à convaincre, pour plusieurs raisons qui sont successivement développées. En particulier, on regrettera que l’interprétation eschatologique, naguère défendue par plusieurs auteurs, ait été négligée.
Géopolitique de la transition énergétique
Authors: Charlez Philippe 
Published: June 2017

Si la 21 e Conférence sur le Climat de 2015 s’est terminée par un « accord cadre » approuvé à l’unanimité, l’accord est contraignant politiquement mais non juridiquement. Cette prise de conscience collective ne doit pas faire oublier que la transition énergétique se heurte à une hétérogénéité de situations historiques, économiques et géographiques et qu’elle ne repose pas sur le seul objectif environnemental mais aussi sur trois autres piliers : sociétal, politique et économique. Un prix élevé du baril signifie croissance pour les Russes mais stagnation ou récession pour les Européens. Quand l’économie américaine développe ses gaz de schiste et provoque l’effondrement du cours du charbon, ce dernier est absorbé par les pays européens les plus avancés en renouvelables au mépris de la réduction de leurs émissions. Les pays riches dont la croissance est en berne pourront-ils financer au nom du passé la future transition de pays émergents en pleine croissance ? De plus, si un ordre mondial de l’énergie s’avère chimérique, il est tout aussi naïf de croire en la loyauté des États nations. Aussi est-ce dans la construction de Confédérations régionales gérant de façon rationnelle leur destin énergétique que se trouve l’issue d’une transition réussie. À ce titre, la transition doit être traitée et ressentie comme une évolution volontaire et non comme une révolution subie.
Pathologies de l’espace public et agitation fasciste
Authors: Voirol Olivier 
Published: June 2017

La présence de mouvements et partis de droite extrême dans la scène politique actuelle incite à revenir sur les recherches de la Théorie critique (de l’école de Francfort) sur l’agitation fasciste et les processus de communication. Les « pathologies de l’espace public » sont le fruit de contradictions objectives non résolues dans la modernité capitaliste. En asséchant l’espace public, son caractère politique et la raison pratique qui s’y déploie, l’agitation fasciste promeut à sa place une communauté fictive annulant tout sujet autonome et faisant de la culture un terreau acclamatif. Ceci permet de resituer l’étude des techniques d’information et de communication, comme des mass media et du journalisme, au sein d’un cadre conceptuel replaçant les activités communicationnelles dans le tissu social, économique et politique ; de là, différentes « leçons » sont tirées de ces recherches de la théorie critique pour analyser l’Internet des droites extrêmes.
Volumosina, a new Nearctic genus for the rare old-growth forest fly Herniosina voluminosa Marshall (Diptera: Sphaeroceridae)
Authors: Roháček Jindřich , Marshall Stephen A. 
Published: June 2017

AbstractVolumosinanew genus (Diptera: Sphaeroceridae: Limosininae) is described to accomodate the enigmatic Nearctic species Herniosina voluminosa Marshall, 1987 and its relationships are discussed. Based on morphological characters Volumosina is treated as part of the Limosina genus group along with Apteromyia Vimmer, 1929, Gigalimosina Roháček, 1983, Herniosina Roháček, 1983, and Limosina Macquart, 1835 but its position within the group remains unresolved. Volumosina voluminosa (Marshall, 1987) new combination is recorded from Canada and redescribed with new distributional and natural history data suggesting that it is an old-growth specialist associated with large woody debris. The gigantism of the male aedeagal complex of V. voluminosa is discussed.

Published: June 2017

Abstract
Long noncoding RNAs (lncRNAs) have emerged as critical regulators of inflammation. To further understand the interaction between inflammatory signaling pathways and lncRNAs, we characterized the function of cardiac and apoptosis-related lncRNA (Carlr), an lncRNA expressed in both mouse and human cells of diverse tissues. Carlr expression is increased following NF-κB signaling in macrophages, with concomitant translocation to, and enrichment of, the transcript in the cytoplasm. Knockdown of Carlr results in impaired expression of NF-κB pathway genes and influences the interaction between macrophages and intestinal cells in an inflammatory environment. In human celiac disease patient samples, increased levels of the Carlr transcript were detected in the cytoplasm, alongside elevated expression of NF-κB pathway genes. These findings suggest that increased Carlr expression and/or cytoplasmic localization is required for efficient NF-κB signaling and is associated with the inflamed tissue state observed in human celiac disease.

<p>The coastal spaces are fragile and complex areas that receive strong pressure because of the many uses and activities that are developed in them. The tourism of sun and beaches is one of the main economic practices present in these spaces that value the physical-natural conditions and their environmental variables. Of all of them, the sea surface temperature (SST) has been the least studied variable, especially associated to tourist destinations. The coastal zone of the province of Buenos Aires, Argentina, concentrates numerous tourist centers like the Partido de la Costa, Pinamar and Villa Gesell that attract in the summer time, a great flow of population. The objective of the present paper was to perform a descriptive and comparative analysis of SST in these parties through the use of monthly satellite images obtained by the Aqua-MODIS satellite-sensor during the period 2003-2013. The results showed a spatial and seasonal behavior of the SST differentiated for the entire study area. The SST for the warm period (January-March) ranged between 21.5 - 24.5°C and for the cold (July-September) between 9.4 - 11.5°C. This difference was lower in the cold period, allowing distinguishing 3 thermal zones with variations smaller than 0.5°C between them: Costa Norte, Costa Centro- Costa Sur, and Pinamar-Villa Gesell. The warm period presented more intense spatial thermal variations between the studied tourist destinations. Four thermal zones with 0.5°C differences were identified: Costa Norte, Costa Centro, Costa Sur, and Pinamar-Villa Gesell.</p>

Abstract. During 2011, two deep-sea observatories focusing on hydrothermal vent ecology were up and running in the Atlantic (Eiffel Tower, Lucky Strike vent field) and the Northeast Pacific Ocean (NEP) (Grotto, Main Endeavour Field). Both ecological modules recorded imagery and environmental variables jointly for a time span of 23 days (7–30 October 2011) and environmental variables for up to 9 months (October 2011–June 2012). Community dynamics were assessed based on imagery analysis and rhythms in temporal variation for both fauna and environment were revealed. Tidal rhythms were found to be at play in the two settings and were most visible in temperature and tubeworm appearances (at NEP). A  ∼  6 h lag in tidal rhythm occurrence was observed between Pacific and Atlantic hydrothermal vents, which corresponds to the geographical distance and time delay between the two sites.
A numerical analysis of biogeochemical controls with physical modulation on hypoxia during summer in the Pearl River estuary

Published: June 2017

Abstract. A three-dimensional (3-D) physical–biogeochemical coupled model was applied to explore the mechanisms controlling the dissolved oxygen (DO) dynamics and bottom hypoxia during summer in the Pearl River estuary (PRE). By using the numerical oxygen tracers, we proposed a new method (namely the physical modulation method) to quantify the contributions of boundary conditions and each source and sink process occurring in local and adjacent waters to the DO conditions. A mass balance analysis of DO based on the physical modulation method indicated that the DO conditions at the bottom layer were mainly controlled by the source and sink processes, among which the sediment oxygen demand (SOD) at the water–sediment interface and the re-aeration at the air–sea interface were the two primary processes determining the spatial extent and duration of bottom hypoxia in the PRE. The SOD could cause a significant decrease in the bottom DO concentrations (averaged over July–August 2006) by over 4 mg L−1 on the shelf off the Modaomen sub-estuary, leading to the formation of a high-frequency zone of hypoxia (HFZ). However, the hypoxia that occurred in the HFZ was intermittent and distributed in a small area due to the combined effects of re-aeration and photosynthesis, which behaved as sources for DO and offset a portion of the DO consumed by SOD. The bottom DO concentrations to the west of the lower Lingdingyang Bay (i.e. the western shoal near Qi'ao Island) were also largely affected by high SOD, but there was no hypoxia occurring there because of the influence of re-aeration. Specifically, re-aeration could lead to an increase in the bottom DO concentrations by ∼ 4.8 mg L−1 to the west of the lower Lingdingyang Bay. The re-aeration led to a strong vertical DO gradient between the surface and the lower layers. As a result, the majority (∼ 89 %) of DO supplemented by re-aeration was transported to the lower layers through vertical diffusion and ∼ 28 % reached the bottom eventually. Additional numerical experiments showed that turning off re-aeration could lead to an expansion of the hypoxic area from 237 to 2203 km2 and result in persistent hypoxia (hypoxic frequency  >  80 %) to the west of the lower Lingdingyang Bay. Compared to re-aeration and SOD, photosynthesis and water column respiration had relatively small impacts on the DO conditions; turning off these two processes increased the hypoxic area to 591 km2. In summary, our study explicitly elucidated the interactive impacts of physical and biogeochemical processes on the DO dynamics in the PRE, which is critical to understanding hypoxia in this shallow and river-dominated estuarine system.

Abstract
Veriflow®Salmonella species (Veriflow SS) is a molecular-based assay for the presumptive detection of Salmonella spp. from environmental surfaces (stainless steel, sealed concrete, plastic, and ceramic tile), dairy (2% milk), raw meat (20%fat ground beef), chicken carcasses, and ready-to-eat (RTE) food (hot dogs). The assay utilizes a PCR detection method coupled with a rapid, visual, flow-based assay that develops in 3 min post-PCR amplification and requires only an 18 h enrichment for maximumsensitivity. The Veriflow SS systemeliminates the need for sample purification, gel electrophoresis, or fluorophore-based detection of target amplification and does not require complex data analysis. This Performance Tested MethodSM validation study demonstrated the ability of the Veriflow SS method to detect low levels of artificially inoculated or naturally occurring Salmonella spp. in eight distinct environmental and food matrixes. Ineach reference comparison study, probability of detection analysis indicated that there was no significant difference between the Veriflow SS method and the U.S. Department of Agriculture Food Safety and Inspection Service MicrobiologyLaboratory Guidebook Chapter 4.06 and the U.S. Food and Drug Administration Bacteriological Analytical Manual Chapter 5 reference methods. A total of 104 Salmonella strains were detected in the inclusivity study, and 35 nonspecific organisms went undetected in the exclusivity study. The study results show that the Veriflow SS method is a sensitive, selective, and robust assay for the presumptive detectionof Salmonella spp. sampled from environmental surfaces (stainless steel, sealed concrete, plastic, and ceramic tile), dairy (2% milk), raw meat (20% fat ground beef), chicken carcasses, and RTE food (hot dogs).
Miniaturized Temperature-Controlled Planar Chromatography (Micro-TLC) as a Versatile Technique for Fast Screening of Micropollutants and Biomarkers Derived from Surface Water Ecosystems and During Technological Processes of Wastewater Treatment

Published: June 2017

Abstract
There is increasing interest in the development of simple analytical systems enabling the fast screening of target components in complex samples. A number of newly invented protocols are based on quasi separation techniques involving microfluidic paper-based analytical devices and/or micro total analysis systems. Under such conditions, the quantification of target components can be performed mainly due to selective detection. The main goal of this paper is to demonstrate that miniaturized planar chromatography has the capability to work as an efficient separation and quantification tool for the analysis of multiple targets within complex environmental samples isolated and concentrated using an optimized SPE method. In particular, we analyzed various samples collected from surface water ecosystems (lakes, rivers, and the Baltic Sea of Middle Pomerania in the northern part of Poland) in different seasons, as well as samples collected during key wastewater technological processes (originating from the “Jamno” wastewater treatment plant in Koszalin, Poland). We documented that the multiple detection of chromatographic spots on RP-18W microplates—under visible light, fluorescence, and fluorescence quenching conditions, and using the visualization reagent phosphomolybdic acid—enables fast and robust sample classification. The presented data reveal that the proposed micro-TLC system is useful, inexpensive, and can be considered as a complementary method for the fast control of treated sewage water discharged by a municipal wastewater treatment plant, particularly for the detection of low–molecular mass micropollutants with polarity ranging from estetrol to progesterone, as well as chlorophyll-related dyes. Due to the low consumption of mobile phases composed of water–alcohol binary mixtures (less than 1 mL/run for the simultaneous separation of up to nine samples), this method can be considered an environmentally friendly and green chemistry analytical tool. The described analytical protocol can be complementary to those involving classical column chromatography (HPLC) or various planar microfluidic devices.
RÉGIME DE CHANGE ET CYCLICITÉ BUDGÉTAIRE DANS LES PAYS AFRICAINS
Authors: BOBBO Amadou 
Published: June 2017

L’objectif de cet article est d’établir, empiriquement, la relation entre le régime de changes et la cyclicité budgétaire. Pour cela, nous estimons plusieurs variantes de la fonction de réaction des dépenses de consommation publique spécifiées en panel dynamique pour un échantillon de 34 pays africains sur la période 1980-2012. En utilisant la méthode des moments généralisés en différence (DIFF-GMM) telle que développée par Arellano et Bond (1991), et en adoptant la classification de facto de Reinhart et Rogoff (2004), nous parvenons à deux principaux résultats : (1) en régimes de change fixe et intermédiaire, la procyclicité budgétaire est amplifiée; (2) en régime flexible, celle-ci est affaiblie.
Maybe Aesop Was Right, the Tortoise Does Win: A Natural History of the Slow Reading Movement
Authors: Niedermeyer W. Jason 
Published: June 2017

In the past decade, there has been a growing recognition that society’s emphasis on speed and efficiency came with some costs: a loss of the ability to appreciate activities and understand their meanings. Recently, this meta-movement has made its way into the literature on literacy, causing the author to embark on an investigation into the veracity of the claims that slow reading might also mean better reading. A natural history approach was adopted for the analysis to evaluate whether there was evolutionary justification for the movement, leading to the review of relevant work in the fields of ethology, psychology, cognitive neuroscience, anthropology, sociology, linguistics, and literacy. The findings reveal an evolutionary push toward both speed and understanding, two aims that eventually come to be at odds in expert readers. It is the conclusion of the author that, from an evolutionary perspective, there may be justification for the start of a slow reading movement, but that it must be paired with practices that develop the capacity to read fast.
Mg2+‐Dependent High Mechanical Anisotropy of Three‐Way‐Junction pRNA as Revealed by Single‐Molecule Force Spectroscopy
Authors: Sun Yang , Di Weishuai , Li Yiran , Huang Wenmao , Wang Xin , Qin Meng , Wang Wei , Cao Yi 
Published: June 2017

AbstractMechanical anisotropy is ubiquitous in biological tissues but is hard to reproduce in synthetic biomaterials. Developing molecular building blocks with anisotropic mechanical response is the key towards engineering anisotropic biomaterials. The three‐way‐junction (3WJ) pRNA, derived from ϕ29 DNA packaging motor, shows strong mechanical anisotropy upon Mg2+ binding. In the absence of Mg2+, 3WJ‐pRNA is mechanically weak without noticeable mechanical anisotropy. In the presence of Mg2+, the unfolding forces can differ by more than 4‐fold along different pulling directions, ranging from about 47 pN to about 219 pN. Mechanical anisotropy of 3WJ‐pRNA stems from pulling direction dependent cooperativity for the rupture of two Mg2+ binding sites, which is a novel mechanism for the mechanical anisotropy of biomacromolecules. It is anticipated that 3WJ‐pRNA can be used as a key element for the construction of biomaterials with controllable mechanical anisotropy.
Role of a Topotactic Electrochemical Reaction in a Perovskite‐Type Anode for Lithium‐Ion Batteries

Published: June 2017

AbstractOne of the mechanisms for some transition‐metal oxides as anodes of a lithium‐ion battery (LIB) is their conversion into variable‐valence oxides or even metals. The conversion reaction involves oxide‐ion transport and the formation/decomposition of Li2O, but very limited research has been done on the oxide‐ion transport of the anodes. Perovskite‐type oxides containing transition elements show high tolerance to oxygen‐deficiency and high oxide‐ion conductivity, which could benefit the oxide‐ion transport and structural stability. In this study, a CaMnO3‐based perovskite involving little volumetric variation upon oxygen uptake/release is examined to study the intermediate oxygen‐deficient product, and the loss of oxygen is found to follow the route of a topotactic electrochemical reaction. In particular, the conversion reaction of the perovskite involves the formation of oxygen‐deficient perovskite and rocksalt‐type CaMnO2 depending on the grain size.
