Authors: Chagnon Jean-Yves 
Published: June 2016

Cet article traite de la création et de l’histoire de l’Association d’hygiène mentale dans le 13e arrondissement de Paris, plus communément dit « le 13e », et ce à travers l’histoire de ses créateurs : Philippe Paumelle, Serge Lebovici, René Diatkine. Psychiatres et psychanalystes, ceux-ci ont élaboré, dans le contexte de l’après-guerre français, un projet communautaire en santé mentale d’orientation psychanalytique, devenu le premier secteur de psychiatrie, modèle institutionnel ayant durablement influencé la pratique de la psychiatrie humaniste en France.
Pratiquer la psychothérapie dans un CSSS : une utopie ?
Authors: Cardinal Vincent 
Published: June 2016

L’auteur s’interroge sur la pratique de la psychothérapie d’orientation analytique en institution et ses conditions de possibilité dans le contexte d’une transformation radicale du milieu de la santé mentale au Québec. Il met en lumière les écueils d’une telle pratique et les vecteurs qui freinent ou qui propulsent certaines formes de psychothérapie dans le champ de la santé mentale en institution. Deux formes de pensée et leurs répercussions sur le système de soins sont examinées : l’introduction des neurosciences et de la pensée gestionnaire sont au centre de ce débat. Enfin, l’auteur propose un modèle de soins qui tente de concilier une perspective psychanalytique et l’allocation des ressources disponibles dans un milieu institutionnel de soins en santé mentale jeunesse.
L’avis des acteurs des séances d’analyse de pratiques professionnelles pour les enseignants stagiaires
Authors: Connac Sylvain 
Published: June 2016

Les enseignants stagiaires en France bénéficient d’une formation initiale qui, parfois, les invite à analyser des situations rencontrées lors de leurs expériences en classe. Cette recherche s’intéresse à un dispositif spécifique : les Groupes de Formation à l’Analyse de Pratiques Professionnelles (GFAPP). Elle consiste à présenter l’avis des animateurs de ces groupes d’analyse (recueillis à partir d’entretiens semi-directifs) ainsi que celui des enseignants stagiaires (collectés par l’intermédiaire d’un questionnaire auto-administré), sur trois années scolaires. Elle met notamment en avant que les séances d’analyse de pratiques participent à une démarche de professionnalisation. Ces séances visent à appréhender la complexité de l’acte d’enseigner et permettent aux professeurs stagiaires de se sentir accompagnés dans l’exercice de leur première année d’enseignement.
Accompagner un moment de transition professionnelle par un dispositif de formation-action réflexif mené auprès de conseillers en orientation et en accompagnement professionnels
Authors: Poulin Martine 
Published: June 2016

La question de la professionnalisation des acteurs fait souvent débat, car elle pourrait sous-entendre qu’un acteur qui se professionnalise n’est pas un bon professionnel voire qu’il n’est pas compétent. Cette position est d’autant plus renforcée quand ces acteurs vivent des moments de transition professionnelle, où les doutes et incertitudes viennent bousculer leur identité professionnelle. Comment dès lors les accompagner au mieux dans ces moments qui questionnement ?
Cet article vise à montrer comment par un dispositif de formation-action réflexif une démarche de professionnalisation peut être, d’une part un processus de construction des sujets leur permettant de prendre conscience de leur bagage d’expérience, de leur professionnalité et, d’autre part un processus contribuant à la construction de leur posture d’apprenance, de sujet apprenant. Il s’agit d’un processus en mouvement qui s’inscrit dans la philosophie de la formation et l’orientation tout au long de la vie, dans lequel le sujet doit se reconnaître comme un acteur au travail, comme un auteur de son travail et comme un sujet en travail sur son activité constructive favorisant ainsi son développement.
Broadening of absorption band by coupled gap plasmon resonances in a near-infrared metamaterial absorber
Authors: Cong Jiawei , Yao Hongbing , Gong Daolei , Chen Mingyang , Tong Yanqun , Fu Yonghong , Ren Naifei 
Published: June 2016

Abstract
We propose a strategy to broaden the absorption band of the conventional metamaterial absorber by incorporating alternating metal/dielectric films. Up to 7-fold increase in bandwidth and ∼95% average absorption are achieved arising from the coupling of induced multiple gap plasmon resonances. The resonance coupling is analytically demonstrated using the coupled oscillator model, which reveals that both the optimal coupling strength and the resonance wavelength matching are required for the enhancement of absorption bandwidth. The presented multilayer design is easily fabricated and readily implanted to other absorber configurations, offering a practical avenue for applications in photovoltaic cells and thermal emitters.
Electric-field-controlled suppression of Walker breakdown and chirality switching in magnetic domain wall motion
Authors: Chen Hong-Bo , Li You-Quan 
Published: June 2016

Abstract
We theoretically study the dynamics of a magnetic domain wall controlled by an electric field in the presence of the spin flexoelectric interaction. We reveal that this interaction generates an effective spin torque and results in significant changes in the current-driven domain wall motion. In particular, the electric field can stabilize the domain wall motion, leading to strong suppression of the current-induced Walker breakdown and thus allowing a higher maximum wall velocity. We can furthermore use this electric-field control to efficiently switch the chirality of a moving domain wall in the steady regime.
Joule heating in spin Hall geometry
Authors: Taniguchi Tomohiro 
Published: June 2016

Abstract
The theoretical formula for the entropy production rate in the presence of spin current is derived using the spin-dependent transport equation and thermodynamics. This theory is applicable regardless of the source of the spin current, for example, an electric field, a temperature gradient, or the Hall effect. It reproduces the result in a previous work on the dissipation formula when the relaxation time approximation is applied to the spin relaxation rate. By using the developed theory, it is found that the dissipation in the spin Hall geometry has a contribution proportional to the square of the spin Hall angle.
Resistance switching memory characteristics of CaF2/Si/CaF2 resonant-tunneling quantum-well heterostructures sandwiched by nanocrystalline Si secondary barrier layers
Authors: Kuwata Yuya , Suda Keita , Watanabe Masahiro 
Published: June 2016

Abstract
A novel resistance switching memory using CaF2/Si/CaF2 resonant-tunneling quantum well heterostructures sandwiched by nanocrystalline Si (nc-Si) as secondary barrier layers has been proposed and the room temperature current–voltage characteristics of the basic resistance switching memory operation have been demonstrated. A resistance switching voltage of 1.0 V, a peak current density of approximately 42 kA/cm2, and an ON/OFF ratio of 2.8 were observed. In particular, more than 28000 write-read-erase cyclic memory operations have been demonstrated by applying pulsed input voltage sequences, which suggests better endurance than the device using a CaF2/CdF2/CaF2 heterostructure.

Abstract
We report epitaxial synthesis of superconducting Cs
x
WO3 (x = 0.11, 0.20, and 0.31) films on Y-stabilized ZrO2 (111) substrates. The hexagonal crystal structure was verified not only for the composition within the stable region of the bulk (x = 0.20 and 0.31), but also for the out-of-range composition (x = 0.11). The onset of the superconducting transition was recorded at 5.8 K for x = 0.11. We found a strong correlation between the superconducting transition temperature (T
C) and the c-axis length, irrespective of the Cs content. These results indicated that the hidden superconducting phase region of hexagonal tungsten bronze is accessible using epitaxial synthesis of lightly doped films.
Two-dimensional concentration distribution of reactive oxygen species transported through a tissue phantom by atmospheric-pressure plasma-jet irradiation

Published: June 2016

Abstract
The two-dimensional concentration distribution of reactive oxygen species (ROSs) transported through an agarose-film tissue phantom by atmospheric-pressure plasma-jet irradiation is visualized using a KI-starch gel reagent. Oxygen addition to helium enhances ROS transportation through the film. A radial ROS distribution pattern at the plasma-irradiated film surface changes into a doughnut-shaped pattern after passing through the film. The ROS transportation speed is 0.14–0.2 mm/min. We suggest that there are two types of ROS transportation pathways in the plasma-irradiated film: linear and circular. The majority of ROSs are transported through the circular pathway. ROS concentration distributions changed markedly with irradiation distance. Diffusive ROS transportation due to a concentration gradient is negligible in plasma-irradiated films.
Light-induced changes in silicon nanocrystal based solar cells: Modification of silicon–hydrogen bonding on silicon nanocrystal surface under illumination
Authors: Kim Ka-Hyun , Johnson Erik V. , Roca i Cabarrocas Pere 
Published: June 2016

Abstract
Hydrogenated polymorphous silicon (pm-Si:H) is a material consisting of a small volume fraction of nanocrystals embedded in an amorphous matrix. pm-Si:H solar cells demonstrate interesting initial degradation behaviors such as rapid initial change in photovoltaic parameters and self-healing after degradation during light-soaking. The precise dynamics of the light-induced degradation was studied in a series of light-soaking experiments under various illumination conditions such as AM1.5G and filtered 570 nm yellow light. Hydrogen effusion experiment before and after light-soaking further revealed that the initial degradation of pm-Si:H solar cells originate from the modification of silicon–hydrogen bonding on the surface of silicon nanocrystals in pm-Si:H.
Microwave-assisted atmospheric pressure plasma polymerization of hexamethyldisiloxane
Authors: Matsubayashi Toshiki , Hidaka Hiroki , Muguruma Hitoshi 
Published: June 2016

Abstract
Microwave-assisted atmospheric pressure plasma polymerization is presented. A system with a re-entrant microwave cavity realizes simple matching, stable plasma, and free space under the orifice of plasma steam. Hexamethyldisiloxane is employed as a monomer, while argon is used as a carrier gas. The effective area of the hydrophobic coating film used corresponds to a circle of 20 mm diameter and the deposition rate considered is 5 nm/min. Matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy shows that the coating film has a large molecular weight (>200 kDa), suggesting that a high-crosslinking and three-dimensional polymer matrix is formed and microwave-assisted atmospheric pressure plasma polymerization is fulfilled.
Atomically flat nickel film grown on synthetic mica
Authors: Tanaka Hiroyuki , Taniguchi Masateru 
Published: June 2016

Abstract
We have grown nickel heteroepitaxially on muscovite and synthetic mica in vacuo for use as substrates for scanning probe microscopy (SPM) and graphene formation. We have determined annealing conditions that could generate atomically flat surfaces (with rms surface roughness of less than 1 nm). Owing to accelerated degradation at temperatures above 600 °C, muscovite mica was unsuitable as a substrate at high growth temperatures. Thermally stable synthetic fluorophlogopite mica [KMg3(AlSi3O10)F2], on the other hand, was found to be stable at 800 °C and successfully employed for the formation of atomically flat films.
Thermal dispersion method for an ultrasonic phased-array transducer
Authors: Choi Euna , Lee Wonseok , Roh Yongrae 
Published: June 2016

Abstract
When the driving voltage of an ultrasonic transducer is increased to improve the quality of ultrasound images, heat is generated inside the transducer, which can burn the patient’s skin and degrade transducer performance. In this study, the method to disperse the heat inside an ultrasonic phased-array transducer has been examined. The mechanism of temperature rise due to heat generation inside the transducer was investigated by numerical analysis and the effects of the thermal properties of the components of the transducer such as specific heat and thermal conductivity on the temperature rise were analyzed. On the basis of the results, a heat-dispersive structure was devised to reduce the temperature at the surface of the acoustic lens of the transducer. Prototype transducers were fabricated to check the efficacy of the heat-dispersive structure. By experiments, we have confirmed that the new heat-dispersive structure can reduce the internal temperature by as much as 50% in comparison with the conventional structure, which confirms the validity of the thermal dispersion mechanism developed in this work.
Control of self-excitation mode in thermoacoustic system using heat phase adjuster
Authors: Kido Aiko , Sakamoto Shin-ichi , Taga Kazusa , Watanabe Yoshiaki 
Published: June 2016

Abstract
The capability of a heat phase adjuster (HPA) to control the resonance mode in a loop-tube-type thermoacoustic system by locally heating the outside is experimentally investigated. It is shown that the HPA enables the resonance mode of the tube to shift to lower modes with higher thermoacoustic conversion efficiency, thus significantly enhancing the energy conversion efficiency. The transition of the resonance mode due to the stepwise change in the input electric power to the HPA is also investigated. As a result, it is demonstrated that the resonance mode changes with the temperature and a threshold exists for the HPA temperature at which the transition is induced. These results suggest the possibility of externally controlling a loop-tube-type thermoacoustic system.

Published: June 2016

Abstract
To characterize skin ulcers for bacterial infection, quantitative ultrasound (QUS) parameters were estimated by the multiple statistical analysis of the echo amplitude envelope based on both Weibull and generalized gamma distributions and the ratio of mean to standard deviation of the echo amplitude envelope. Measurement objects were three rat models (noninfection, critical colonization, and infection models). Ultrasound data were acquired using a modified ultrasonic diagnosis system with a center frequency of 11 MHz. In parallel, histopathological images and two-dimensional map of speed of sound (SoS) were observed. It was possible to detect typical tissue characteristics such as infection by focusing on the relationship of QUS parameters and to indicate the characteristic differences that were consistent with the scatterer structure. Additionally, the histopathological characteristics and SoS of noninfected and infected tissues were matched to the characteristics of QUS parameters in each rat model.

Authors: Gamaleev Vladislav , Okamura Yo , Kitamura Kensuke , Hashimoto Yusuke , Oh Jun-Seok , Furuta Hiroshi , Hatta Akimitsu 
Published: June 2016

Abstract
Microplasma discharge in sea water for optical emission spectroscopy was investigated using a needle-to-plane electrode system. The electrodes of a Pd needle and a Pt plate were placed with a gap of 25 µm in typical artificial sea water or locally sampled natural deep sea water. A pulse current source, consisting of a MOSFET switch, a capacitor, an inductor and the resistance of the sea water between the electrodes, was used. The circuit parameters were optimized to decrease the breakdown voltage and the spark duration to suppress erosion of the electrodes. Using a microgap configuration, spark discharges were reproducibly ignited in the highly conductive sea water at low breakdown voltages. The ignition of spark discharges required not only a critical voltage sufficient for breakdown, but also a critical energy for preheating of the sea water, sufficient for bubble formation. The possibility of using optical emission spectroscopy of microplasma in water is shown for identifying elemental composition of sea water.
Current-induced domain wall motion attributed to spin Hall effect and Dzyaloshinsky–Moriya interaction in Pt/GdFeCo (100 nm) magnetic wire
Authors: Kurokawa Yuichiro , Kawamoto Masaya , Awano Hiroyuki 
Published: June 2016

Abstract
We investigated the current-induced domain wall motion (CIDWM) in Pt/GdFeCo bilayer wires where the thicknesses of the GdFeCo layer are 110 and 150 nm. We found that the direction of CIDWM in the Pt/GdFeCo wires is the same as the current flow direction. The velocity of the domain wall depends on the in-plane magnetic field. These results indicate that the CIDWM along the current direction in the Pt/GdFeCo wires is probably attributed to the spin Hall effect and Dzyaloshinsky–Moriya interaction. Generally, these effects do not appear in thick magnetic wires because they effectively occur at the interfaces of a heavy metal and magnetic layers. Therefore, these results are interesting phenomena because they probably suggest that the spin Hall effect and Dzyaloshinsky–Moriya interaction in the Pt/GdFeCo wire have an anomalously long-range influence.
Magnetic layer thickness dependence of all-optical magnetization switching in GdFeCo thin films

Published: June 2016

Abstract
To clarify the relationship between all-optical magnetization switching (AOS) and nonlocal and nonadiabatic energy dissipation process, we focus on the contribution from energy dissipation in the depth direction. Differently designed structure dependence of created magnetic domain is observed from the reversal phenomenon, AOS, or multidomains by thermomagnetic nucleation (TMN) in GdFeCo multilayer thin films. TMN depends on the shared absorbed energy throughout the continuous metallic volume. On the other hand, AOS critically depends on nonadiabatic energy dissipation process with the electron system in sub-picoseconds. Furthermore, the laser fluence dependence of AOS-created domain sizes indicates that the value of irradiated laser fluence threshold per magnetic domain volume is almost constant. However, a lower laser irradiation fluence below 1–2 mW has a larger value and thickness dependence. From these results, we suggest that AOS depends on energy dissipation from the incident surface in the depth direction for a few picoseconds.

Authors: Ya Xiaorui , Tanaka Terumitsu , Matsuyama Kimihide 
Published: June 2016

Abstract
In the present study, the rotation and switching of a vortex core in submicron-size square dots were numerically analyzed by micromagnetic simulation. This study clarified that the eigenfrequency of the vortex core is strongly dependent on the magnetostatic energy and that rapid switching can be realized by circularly polarized fields with practical amplitudes at the corresponding eigenfrequency. The inductive detection of vortex core rotation, which can distinguish vortex core polarity, was successfully demonstrated and the structural design of the detector was optimized.

As (x = 6.9%) layers prepared by ion implantation and subsequent pulsed laser annealing have been studied using the magnetooptical transversal Kerr effect (TKE) and spectral ellipsometry. Ellipsometry data reveal the good crystal quality of the layers. The samples show ferromagnetic behaviour below 77 K. Near the absorption edge of the parent InAs semiconductor, large TKE values are observed. In the energy regions of the transitions in the Γ and L critical points of the InAs Brillouin zone, there are several clearly defined structures in the low-temperature TKE spectra. We have calculated the spectral dependences of the diagonal and nondiagonal components of the permittivity tensor (PT), as well as the spectrum of magnetic circular dichroism (MCD) for our samples. A number of extrema in the obtained MCD and PT spectra are close to the energies of transitions in the critical points of the parent semiconductor band structure, which confirms the intrinsic ferromagnetism of the Mn-doped InAs layers.
Nighttime mesospheric hydroxyl enhancements during SEP events and accompanying geomagnetic storms: Ionization rate modeling and Aura satellite observations
Authors: Verkhoglyadova O. P. , Wissing J. M. , Wang S. , Kallenrode M.‐B. , Zank G. P. 
Published: June 2016

AbstractWe quantify the effects of combined precipitating solar protons and magnetospheric electrons on nighttime odd hydrogen density enhancements during two solar energetic particle (SEP) events accompanied by strong geomagnetic storms. We perform detailed modeling of ionization rates for 7–17 November 2004 and 20–30 August 2005 intervals with improved version 1.6 of the Atmospheric Ionization Module Osnabrück model. Particle measurements from Geostationary Operational Environmental Satellites and Polar Orbiting Environmental Satellites are sorted and combined in 2 h intervals to create realistic particle precipitation maps that are used as the modeling input. We show that modeled atmospheric ionization rates and estimated peak odd hydrogen (primarily hydroxyl) production from 0.001 hPa to 0.1 hPa atmospheric pressure levels during these intervals are consistent with enhancements in nighttime averaged zonal odd hydrogen densities derived from newly reprocessed and improved data set of Microwave Limb Sounder instrument on board Aura satellite. We show that both precipitating SEPs and magnetospheric electrons contribute to mesospheric ionization and their relative contributions change throughout the intervals. Our event‐based modeling results underline the importance of the combined ionization sources for odd hydrogen chemistry in the middle atmosphere.
