ABSTRACT
We derive accretion flow properties of the transient black hole candidate (BHC) MAXI J1543–564 using the RXTE data. We use the two-component advective flow (TCAF) solution to fit the data of the initial rising phase of outburst (from 2011 May 10 to 15). The 2.5–25 keV spectra are fitted using the TCAF solution fits file as a local additive table model in XSPEC. We extract physical flow parameters such as the two-component (Keplerian disk and sub-Keplerian halo) accretion rates and size and the property of the Compton cloud (post-shock region close to a black hole). Similar to other classical transient BHCs, monotonic evolution of low-frequency quasi-periodic oscillations (QPOs) is observed during the rising phase of the outburst, which is fitted with the propagating oscillatory shock (POS) model, which describes how the Compton cloud properties change from day to day. From the nature of variations of TCAF model fitted physical flow parameters and QPOs, we only found hard-intermediate and soft-intermediate spectral states during this phase of the outburst under study. We also calculated the frequency of the dominating QPOs from the TCAF model fitted shock parameters and found that they roughly match with the observed and POS model fitted values. From our spectro-temporal study of the source with TCAF and POS models, the most probable mass of the BHC is found to be 12.6–14.0 M

Dissocier les effets facilitants et les effets délétères de l’émotion sur la cognition
Authors: Dolcos Florin , Denkova Ekaterina 
Published: August 2016

L’émotion est une « arme à double tranchant » qui peut soit améliorer, soit détériorer des aspects divers de notre cognition et de notre comportement. Par exemple, la charge émotionnelle d’un événement peut attirer l’attention et renforcer la mémoire de cet événement, par contre une information émotionnelle, sans pertinence pour la tâche cognitive en cours, peut être considérée comme une distraction et ainsi entraîner la détérioration de la performance à cette tâche. Ces effets opposés de l’émotion peuvent être identifiés à différents niveaux, à la fois au sein du même processus cognitif et à travers des processus cognitifs différents, ou à un niveau plus général, comme dans le cas de la réponse au stress. Cette revue présente des données nouvelles qui permettent de mieux comprendre les facteurs qui influencent les effets opposés de l’émotion sur la cognition chez le sujet sain ainsi que dans le cas de dysfonctionnements liés à des désordres affectifs. Les questions discutées dans cette revue sont d’une grande importance pour arriver à mieux comprendre les mécanismes impliqués dans les relations entre émotion et cognition dans le fonctionnement sain ainsi que dans les troubles émotionnels où les effets de l’émotion sur la cognition sont intensifiés. Globalement, la présente revue souligne la nécessité de considérer et identifier les facteurs qui peuvent avoir une influence sur les effets de facilitation et les effets de dégradation des émotions sur la cognition.
L’influence de la puberté sur les circuits neuronaux sous-tendant la régulation des émotions : implications pour la compréhension des risques de troubles affectifs
Authors: Ladouceur Cecile D. 
Published: August 2016

L’adolescence, avec le début de la puberté, représente une période développementale durant laquelle il existe une plus grande vulnérabilité pour l’émergence de psychopathologies telle que les troubles affectifs. C’est également une importante période de maturation des circuits neuronaux sous-tendant la régulation des émotions, suggérant ainsi la possibilité que certains mécanismes neurodéveloppementaux puissent contribuer à cette vulnérabilité. Bien que plusieurs études épidémiologiques suggèrent une prévalence plus élevée de troubles dépressifs durant la puberté chez les filles, les chercheurs ne font que commencer à se pencher sur la question de l’influence spécifique de la puberté sur le développement des circuits fronto-striato-limbiques sous-tendant la régulation des émotions. Cet article inclut a) la présentation d’études en imagerie par résonance magnétique axées sur l’étude du développement cérébral sous-tendant les émotions pendant la puberté ; b) le traitement de l’importance de l’étude du développement cérébral pendant la puberté afin d’élucider les facteurs prédisposant aux troubles affectifs ; c) une intégration des recherches scientifiques en neuroscience affective du développement en vue de développer des stratégies d’intervention pour les troubles affectifs chez l’adolescent.
Cognition sociale et sens de l’agentivité en autisme : de l’action à l’interaction
Authors: Lafleur Alexis , Soulières Isabelle , Forgeot d’Arc Baudoin 
Published: August 2016

Le sens de l’agentivité (SdA) consiste à détecter que l’on est la cause d’une action (Gallagher, 2000). Il est lié au contrôle moteur, mais également à la conscience de soi et pourrait jouer un rôle important dans l’interaction sociale. Le trouble du spectre de l’autisme (TSA) est caractérisé par une altération des interactions sociales et de la communication (DSM-5 ; APA, 2013), et est souvent perçu comme relevant d’un déficit primaire de fonctions spécifiques à la cognition sociale. Pourtant, le contrôle moteur est également altéré dans le TSA. Nous faisons l’hypothèse que les symptômes moteurs et l’atteinte de l’interaction sociale pourraient relever d’une même atteinte du SdA. Nous présentons d’abord les modèles explicatifs généraux et les bases neurofonctionnelles du SdA implicite et explicite (Synofziket al., 2008), puis les manifestations de ses perturbations dans d’autres troubles neuropsychiatriques comme la schizophrénie. Dans le TSA, la formation atypique des modèles internes de l’action lors de l’apprentissage moteur (Haswellet al., 2009) pourrait être à l’origine de l’altération du SdA implicite. Le manque de fidélité des indices d’agentivité sensorimoteurs (Zallaet al., 2015) pourrait de façon concomitante entraîner l’altération du SdA explicite. Nous discutons les principales manifestations cliniques du TSA qui seraient reliées aux altérations du SdA (difficultés dans la théorie de l’esprit et l’imitation, déficits de la coordination et des praxies, etc.)

Published: August 2016

Soumis à des mouvements de population importants, la Guyane française et son centre pénitentiaire abritent une population métissée chez qui l’histoire récente a laissé une empreinte forte (tremblement de terre en Haïti, guerre civile au Suriname, violence liée à l’orpaillage et au trafic de stupéfiants). Ces événements de vie négatifs apparaissent comme autant de vecteurs potentiels de psychotraumatismes. Dans ces conditions, il nous a paru essentiel de mettre l’accent sur le repérage du trouble de stress post-traumatique (TSPT) dans cette population sensible. À l’aide d’entretiens d’accueil dédiés, nous nous sommes proposé de repérer les TSPT, de décrire sur un plan sociodémographique la population étudiée et de rechercher les comorbidités psychiatriques. Le résultat principal de cette étude était une prévalence du TSPT de 17 % chez les arrivants en détention. Le MINI 5.0 a montré une prévalence plus élevée des pathologies psychiatriques dans le groupe présentant un TSPT avec un lien très fort (p < 0,005) pour l’épisode dépressif majeur actuel, l’épisode maniaque ou hypomaniaque actuel et le risque suicidaire. Cette étude appuie la nécessité d’avoir un dépistage systématique du TSPT chez les arrivants en détention. Cette pathologie est à la fois fréquente dans cette population et invalidante, mais ce sont ses comorbidités, dont le potentiel suicidaire, qui font tout l’enjeu d’un repérage précoce.
Southwestward weakening of Wyoming lithosphere during the Laramide orogeny
Authors: Gao Min , Fan Majie , Moucha Robert 
Published: August 2016

AbstractThe mechanism of Laramide deformation in the central Rocky Mountains remains enigmatic. It is generally agreed that the deformation resulted from low‐angle subduction of the Farallon plate beneath the North American plate during the latest Cretaceous‐early Eocene; however, recent studies have suggested the importance of slab removal or slab rollback in causing this deformation. Here we infer Wyoming lithosphere structure and surface deformation pattern by conducting 2‐D flexural subsidence modeling in order to provide constraints on the mechanism of Laramide deformation. We assume that Wyoming lithosphere behaved as an infinite elastic plate subject to tectonic loading of mountain ranges and conduct 2‐D flexural subsidence modeling to major Laramide basins to document lithospheric stiffness and mountain load height. Our results show that the stiffness of Wyoming lithosphere varied slightly in each basin during the ~30 Myr duration of the Laramide deformation and decreased from northeastern Wyoming (Te = 32–46 km) to southwestern Wyoming (Te = 6–9 km). Our results also imply that the increase of equivalent load height of major Laramide ranges accelerated during the early Eocene. We propose that the bending stresses induced by the topographic load of the Sevier fold‐and‐thrust belt combined with crust‐mantle decoupling initiated by the overthickened Sevier hinterland and the end loads due to the low‐angle subduction at the western edge of the thick Wyoming craton have caused the southwestward decrease of lithospheric stiffness in Wyoming. Moreover, we attribute the accelerated load height gain during the early Eocene to both dynamic and isostatic effects associated with slab rollback.
Ecosystem resilience to the Millennium drought in southeast Australia (2001–2009)
Authors: Sawada Yohei , Koike Toshio 
Published: August 2016

AbstractThe prolonged Millennium drought in southeast Australia (2001–2009) provides a unique opportunity to analyze the responses of a semiarid ecosystem to severe droughts. In this paper, we analyzed vegetation dynamics in the Millennium drought using visible/infrared observations, passive microwave observations, and a simple ecohydrological model. The satellite observations indicated that the ecosystem maintained its greenness in the Millennium drought, although the total aboveground biomass was significantly decreased by water scarcity. The results of our numerical experiments suggested that the resilience of vegetation greenness to the drought could be explained by a carbon allocation strategy that was sensitive to light and water availability and by temporal changes in vegetation traits. Our numerical experiments successfully simulated the decrease of total aboveground biomass with unchanged vegetation greenness during the Millennium drought.

AbstractLimit of detection (LOD), limit of quantification, and the dynamic range of detection of hepatitis B surface antigen antibody (anti‐HBs) using a surface plasmon resonance (SPR) chip‐based approach with Pichia pastoris‐derived recombinant hepatitis B surface antigen (HBsAg) as recognition element were established through the scouting for optimal conditions for the improvement of immobilization efficiency and in the use of optimal regeneration buffer. Recombinant HBsAg was immobilized onto the sensor surface of a CM5 chip at a concentration of 150 mg/L in sodium acetate buffer at pH 4 with added 0.6% Triton X‐100. A regeneration solution of 20 mM HCl was optimally found to effectively unbind analytes from the ligand, thus allowing for multiple screening cycles. A dynamic range of detection of ∼0.00098–0.25 mg/L was obtained, and a sevenfold higher LOD, as well as a twofold increase in coefficient of variance of the replicated results, was shown as compared with enzyme‐linked immunosorbent assay (ELISA). Evaluation of the assay for specificity showed no cross‐reactivity with other antibodies tested. The ability of SPR chip‐based assay and ELISA to detect anti‐HBs in human serum was comparable, indicating that the SPR chip‐based assay with its multiple screening capacity has greater advantage over ELISA.

AbstractIm Brandfall müssen im Regelfall zwei voneinander unabhängige Rettungswege für die Flüchtenden zur Verfügung stehen. Die brandschutztechnische Ausbildung dieser Wege wird in den entsprechenden Landesbauordnungen geregelt. In diesem Artikel werden hierzu einige wichtige Details näher erläutert. Unter anderem sind nicht alle auf dem Markt angebotenen Rettungssysteme, wie z. B. fest installierte Leitern, als baulicher Rettungsweg geeignet.Der zweite Rettungsweg führt im Wohnungsbau üblicherweise über die Rettungsgeräte der Feuerwehr. Je nach Einsatzstrategie und vorhandenem Equipment setzt sie hierzu unterschiedliche Geräte ein. Nach den Einsatzberichten der Berliner Feuerwehr aus den Jahren 2012/13 wurden auch häufiger verqualmte Treppenräume zur Rettung von Personen genutzt. Um die Flüchtenden vor den toxischen Brandrauchgasen zu schützen, kamen bei diesen Rettungsaktionen Fluchthauben zum Einsatz oder eine temporäre Rauchfreiheit wurde durch Überdruck belüfter erzeugt.

AbstractIn obesity, the increment of adiposity levels disrupts the whole body homeostasis, promoting an over production of oxidants and inflammatory mediators. The current study aimed to characterize the transcriptomic changes promoted by supplementation with eicosapentaenoic acid (EPA, 1.3 g/day), α‐lipoic acid (0.3 g/day), or both (EPA + α‐lipoic acid, 1.3 g/day + 0.3 g/day) in subcutaneous abdominal adipose tissue from overweight/obese healthy women, who followed a hypocaloric diet (30% of total energy expenditure) during ten weeks, by using a microarray approach. At the end of the intervention, a total of 33,297 genes were analyzed using Affymetrix GeneChip arrays. EPA promoted changes in extracellular matrix remodeling gene expression, besides a rise of genes associated with either chemotaxis or wound repair. α‐Lipoic acid decreased expression of genes related with cell adhesion and inflammation. Furthermore, α‐lipoic acid, especially in combination with EPA, upregulated the expression of genes associated with lipid catabolism while downregulated genes involved in lipids storage. Together, all these data suggest that some of the metabolic effects of EPA and α‐lipoic acid could be related to their regulatory actions on adipose tissue metabolism. © 2016 BioFactors, 43(1):117–131, 2017
Population-based study of ruptured abdominal aortic aneurysm
Authors: Laine M T , Laukontaus S J , Kantonen I , Venermo M 
Published: August 2016

Abstract

Background
The incidence of abdominal aortic aneurysms (AAAs) and their rupture has been reported to be decreasing. The aim was to evaluate trends in ruptured AAA (rAAA) incidence in the hospital district of Helsinki and Uusimaa (HUS) in southern Finland. This was a population-based retrospective review of all patients with rAAA in this well defined geographical area during 2003–2013.

Methods
Data for all patients treated for rAAA at Helsinki University Hospital, the only vascular surgery centre in an area of 1·5 million inhabitants, were collected from local vascular registry. All deaths attributed to rAAA were obtained from the cause of death registry of Statistics Finland.

Results
The mean(s.d.) age of the 712 patients with rAAA was 76·5(9·6) years; 76·7 per cent of them were men. Only 330 patients (46·3 per cent of those with rAAA) arrived alive at Helsinki University Hospital. The turn-down rate for surgical treatment was 10·3 per cent. Of the 296 patients operated on, 199 (67·2 per cent) were alive at 30 days. Only 27·9 per cent of all patients were alive 30 days after rupture of the AAA. The incidence of rAAA was 4·3 per 100 000 inhabitants and the mortality rate was 3·2 per 100 000 inhabitants. A decreasing trend was seen in incidence and mortality during the 11-year study interval.

Conclusion
The incidence of rAAA is decreasing in the HUS district. Mortality from rAAA remains very high, because half of the patients die before reaching the hospital.
Effect of Hydrogen Pretreatment of Platinum Nanoparticles on their Catalytic Properties: Reactions with Alkyl Radicals – A Mechanistic Study

Published: August 2016

AbstractMethyl radicals react with platinum nanoparticles (NPs) suspended in aqueous solutions to form (Pt0‐NPs)‐(CH3)n as a stable major product. Hydrogen gas treatment of the Pt0‐NPs affects the composition of the products and the surface reactions. The results clearly point out that pretreatment of Pt0‐NPs and (Pt0‐NPs)‐(CH3)n with H2 considerably affects their reactions with methyl radicals. The implications of the results on catalytic processes are discussed.
Continuous‐Flow Synthesis and Functionalization of Magnetite: Intensified Process for Tailored Nanoparticles

Published: August 2016

AbstractThe spinning disc reactor (SDR) is used for the size‐selective synthesis and functionalization of nanoscale superparamagnetic iron oxide particles in a single‐step continuous‐flow process. Nanometer‐sized magnetite (Fe3O4) particles are precipitated in a highly sheared thin liquid film on a rapidly rotating disc. A novel liquid‐liquid synthesis is presented whereas control over particle size is reached via adjustable micromixing properties on the disc. The nanoparticles with tailored size, narrow size distribution, and high saturation magnetization can thus meet the special requirements for the use in biotechnological, medical, and catalytic applications. The functionalization of the particles with oleic acid for higher biocompatibility and better dispersibility is accomplished in the SDR in a single step.
Influence of Bubble Bouncing on Mass Transfer and Chemical Reaction

Published: August 2016

AbstractThe hydrodynamics of bubbly flows is dominated by bubble‐induced turbulence and bubble‐bubble interactions. Both phenomena influence the gas‐liquid mass transfer as well as the mixing of reactants. If the time scales of mass transfer and mixing are in the same order as the time scales of a parallel‐consecutive reaction, the yield and selectivity will be affected by the local hydrodynamics. An experimental setup is presented that enables the investigation of mass transfer during well‐defined and adjustable bubble collisions. The influence of CO2 bubble collisions on mass transfer is measured and modeled with a modified Sherwood number correlation. Further visualization of the concentration field in the vicinity of O2 bubbles by means of laser‐induced fluorescence demonstrates the dependency of mass transfer from a chemical reaction and permits the development of a first model approach.

Published: August 2016

AbstractHerein, a thermal decomposition method was utilised to fabricate pure and mixed manganese and ruthenium oxides as catalysts for the oxygen evolution reaction (OER). X‐ray photoelectron spectroscopy (XPS) and X‐ray diffraction (XRD) reveal the manganese and ruthenium species produced at an annealing temperature of 600 °C to be Mn2O3 and RuO2/Ru, respectively. A number of the mixed Mn/Ru oxides exhibit overpotential values approximately 200 mV lower than previously reported for Mn2O3/RuO2 oxides (at a current density of 10 mA cm−2) for the OER, whereas the Mn 50 material exhibits similar overpotentials reported in the literature for RuO2. Turnover frequency (TOF) numbers for the Mn/Ru oxides were also calculated, and the results show that the TOF values for some of the materials in this work are higher than RuO2. XPS analysis indicates a change in chemical environment of the Mn/Ru materials, which exhibit higher TOF values. Subsequently, the pure Ru 100 material used in this study has a lower overpotential at 10 mA cm−2, as compared to previously reported values in the literature for RuO2 in alkaline media. This may be attributed to the presence of metallic Ru found in the film or the decrease in crystallite size, as determined by XRD. XPS analysis was also carried out after the OER to help determine the order of activity of the materials in this work.
Kinetics of Multi‐Step Redox Processes by Time‐Resolved In Situ X‐ray Diffraction

Published: August 2016

AbstractThe kinetics of redox reactions of iron oxide in oxygen carrier 50Fe2O3/MgAl2O4 are examined using different time‐resolved techniques. Reduction kinetics are studied by H2 temperature‐programmed reduction (H2‐TPR) monitored by time‐resolved in situ XRD. In contrast to conventional TPR, in situ XRD distinguishes the three‐stage reduction of Fe2O3 → Fe3O4 → FeO → Fe. It also shows that the oxidation of Fe → Fe3O4 by CO2 has no intermediate crystalline phases, explaining why its kinetics can easily be investigated by conventional CO2 temperature‐programmed oxidation (CO2‐TPO). A shrinking core model which takes into account solid state diffusion allows describing the experimental data.
Magnetic demulsifier prepared by using one‐pot reaction and its performance for treating oily wastewater

Published: August 2016

AbstractIn this study, a magnetic demulsifier, called M‐DMEA, was prepared by “one‐pot” synthesis through the pyrolysis of ferric triacetylacetonate (Fe(acac)3) in DMEA 1231, which is a type of polyether demulsifier used in oil fields. The morphologies and phase compositions of the M‐DMEA nanoparticles were determined by transmission electron microscopy and X‐ray diffraction, respectively. The presence of surface coating was confirmed by using Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analyses (TGA). Magnetic property was measured by vibrating sample magnetometer. The demulsification of M‐DMEA for treating oily wastewater produced from polymer flooding (OWPF) was investigated. It was found that the oil removal of M‐DMEA reached 96.0 % at the concentration of 4.0 g/L. In addition, M‐DMEA can be recycled and reused by using an external magnet. The results showed that there was a significant decrease in the oil removal after two cycles because the polymer residue remaining in OPWF, namely partially hydrolyzed polyacrylamide (HPAM), was adsorbed onto the surface of M‐DMEA.
