Al2O3 Thin Layer Formed inside Porous Membrane Using Spray Synthesis Method and Its Application

Aluminum oxide (Al2O3) films have been investigated for use in various applications, and numerous deposition techniques have been reported. The spray synthesis method has the advantage of forming a thin layer of crystal at low temperatures using the appropriate precursors. A precursor prepared by diluting Methylaluminoxane with N-methyl pyrrolidone was sprayed onto a porous membrane while varying conditions such as the substrate temperature, feeding speed, and spray amount. The solution penetrated the film during spray application, and the ultra-thin layers deposited on the side wall of the internal pores were observed using a cross-sectional transmission electron microscope (XTEM). The lattice image obtained using the TEM and the composition analysis conducted using a scanning TEM and an energy-dispersive X-ray spectroscope suggest that this thin layer is a layer of Al2O3. The formation of Al2O3 occurred at lower temperatures than in previous reports. This is a major advantage for applications with low-melting-point materials. The most suitable spraying conditions were determined based on the state of deposition on the surface and inside the membrane. These conditions were applied to a three-layer separator for lithium-ion batteries and their effect on thermal stability was investigated. Through heating experiments and XRD analysis, it was confirmed that the shrinkage and melting of the separator are suppressed by spraying. This process can be expected to have wide applications in low-melting-point materials such as polyolefin.Citation: Imai, M.; Kubota, T.; Miyazawa, A.; Aoki, M.; Mori, H.; Komaki, Y.; Yoshino, K.

Software Defined Networking（SDN） ギジュツ ト ソノ カソウカ

video/mp4ネットワークにおけるパケット転送処理を、その装置の外部からプログラム可能にすることにより、従来のプロトコルに縛られない、独自のネットワークの仕組みを実現するSoftware Defined Networking (SDN)と呼ばれる技術が広く注目されている。独立行政法人情報通信研究機構では、このSDN技術の一つであるOpenFlow技術の広域実証実験環境RISE(Research Infrastructure for large-Scale network Experiments)を構築し、運用を行っている。本講演では、このRISEにおける当機構での技術開発の取り組みを中心に紹介する。講演日: 平成25年7月8日講演場所: 情報科学研究科大講義室L1講演者所属: (独)情報通信研究機構vide

Inhibitory Control in Bulimic-Type Eating Disorders: A Systematic Review and Meta-Analysis

<div><p>The aim of this meta-analysis was to summarise data from neuropsychological studies on inhibitory control to general and disease-salient (i.e., food/eating, body/shape) stimuli in bulimic-type eating disorders (EDs). A systematic literature search was conducted to identify eligible experimental studies. The outcome measures studied included the performance on established inhibitory control tasks in bulimic-type EDs. Effect sizes (Hedges' <i>g</i>) were pooled using random-effects models. For inhibitory control to general stimuli, 24 studies were included with a total of 563 bulimic-type ED patients: 439 had bulimia nervosa (BN), 42 had anorexia nervosa of the binge/purge subtype (AN-b), and 82 had binge eating disorder (BED). With respect to inhibitory control to disease-salient stimuli, 12 studies were included, representing a total of 218 BN patients. A meta-analysis of these studies showed decreased inhibitory control to general stimuli in bulimic-type EDs (<i>g</i> = −0.32). Subgroup analysis revealed impairments with a large effect in the AN-b group (<i>g</i> = −0.91), impairments with a small effect in the BN group (<i>g</i> = −0.26), and a non-significant effect in the BED group (<i>g</i> = −0.16). Greater impairments in inhibitory control were observed in BN patients when confronted with disease-salient stimuli (food/eating: <i>g</i> = −0.67; body/shape: <i>g</i> = −0.61). In conclusion, bulimic-type EDs showed impairments in inhibitory control to general stimuli with a small effect size. There was a significantly larger impairment in inhibitory control to disease salient stimuli observed in BN patients, constituting a medium effect size.</p></div
