Event-based nonfragile state estimation for memristive recurrent neural networks with stochastic cyber-attacks and sensor saturations

引用

Chinese Physics B 2024年第7期33卷 126-135页

作者：邵晓光张捷鲁延娟 School of Automation Nanjing University of Science and TechnologyNanjing 210094China School of Electronics and Information Engineering Changchun University of Science and TechnologyChangchun 130022China

This paper addresses the issue of nonfragile state estimation for memristive recurrent neural networks with proportional delay and sensor saturations. In practical engineering, numerous unnecessary signals are transmitted to the estimator through the networks, which increases the burden of communication bandwidth. A dynamic event-triggered mechanism,instead of a static event-triggered mechanism, is employed to select useful data. By constructing a meaningful Lyapunov–Krasovskii functional, a delay-dependent criterion is derived in terms of linear matrix inequalities for ensuring the global asymptotic stability of the augmented system. In the end, two numerical simulations are employed to illustrate the feasibility and validity of the proposed theoretical results.

Electrochemical Realization of 3D Interconnected MoS3/PPy Nanowire Frameworks as Sulfur-Equivalent Cathode Materials for Li-S Batteries

Energy & Environmental Materials 2024年第2期7卷 13-21页

作者： Hongtao Yu Andreas Siebert Shilin Mei Raul Garcia-Diez Roberto Félix Ting Quan Yaolin Xu Johannes Frisch Regan G.Wilks Marcus B?r Chun Pei yan lu Department for Electrochemical Energy Storage Helmholtz-Zentrum Berlin für Materialien und Energie Gmb H (HZB) Guangdong Province Key Laboratory of Durability for Marine Civil Engineering School of Civil Engineering Shenzhen University Department of Interface Design HZB Energy Materials In-Situ Laboratory Berlin (EMIL) Helmholtz-Institute Erlangen-Nürnberg for Renewable Energy (HI ERN) Department of Chemistry and Pharmacy Friedrich-Alexander-Universit?t Erlangen-Nürnberg Institute of Chemistry University of Potsdam

The development of freestanding and binder-free electrode is an effective approach to perform the inherent capacity of active materials and promote the mechanism study by minimizing the interference from additives. Herein, we construct a freestanding cathode composed of MoS3/PPy nanowires（NWs） deposited on porous nickel foam（NF）(MoS3/PPy/NF) through electrochemical methods, which can work efficiently as sulfur-equivalent cathode material for Li-S batteries. The structural stability of the MoS3/PPy/NF cathode is greatly enhanced due to its significant tolerance to the volume expansion of MoS3during the lithiation process,which we ascribe to the flexible 3D framework of PPy NWs, leading to superior cycling performance compared to the bulk-MoS3/NF reference. Eliminating the interference of binder and carbon additives, the evolution of the chemical and electronic structure of Mo and S species during the discharge/charge was studied by X-ray absorption near-edge spectroscopy（XANES）. The formation of lithium polysulfides was excluded as the driving cathode reaction mechanism, suggesting the great potential of MoS3as a promising sulfur-equivalent cathode material to evade the shuttle effect for Li-S batteries. The present study successfully demonstrates the importance of structural design of freestanding electrode enhancing the cycling performances and revealing the corresponding mechanisms.

目的探讨青光眼患者接受虚拟现实视觉训练后,视盘相关结构参数的变化情况及影响视盘结构改变的相关因素。方法前瞻性非随机对照试验。收集2021年10月至2022年10月期间就诊于北京世纪坛医院眼科的青光眼患者,根据个人意愿选择进入训练组或对照组,分别给予或不给予3个月的虚拟现实视觉训练。在入组时及3个月后使用相干光层析成像检查患者双眼视盘的盘沿面积、视杯容积、视盘面积、杯盘比等参数,分析两组各参数的变化情况。并对训练组进行多因素分析,采用比值比(OR)分析患者性别、年龄、视野指数和平均缺损等因素对视觉训练影响视盘结构改变作用的影响。结果最终纳入青光眼患者53例(101只眼),其中训练组27例(51只眼),男性19例,女性8例,年龄为48.0(40.0,61.0)岁;对照组26例(50只眼),男性26例,女性11例,年龄为54.0(38.0,63.0)岁。经过3个月视觉训练后,与对照组相比,训练组训练前后的视杯容积差值为-0.006(-0.050,0.015)mm3(P<0.05)、盘沿面积差值为0.00(-0.04,0.05)mm^(2)(P<0.05)。在训练组内,性别(OR=4.217,95%置信区间为1.188~14.966)对视觉训练后盘沿面积的改变有影响作用。平均缺损值(OR=1.526,95%置信区间为0.245~9.491)对视觉训练后盘沿面积的改变无显著影响作用。结论虚拟现实视觉训练可以使青光眼患者视盘的盘沿面积增大、视杯容积减小;男性青光眼患者的盘沿面积在视觉训练后更易增加。

Interlayer Magnetic Interaction in the CrI_(3)/CrSe_(2) Heterostructure

Chinese Physics Letters 2024年第5期41卷 85-89页

作者：王秋皓倪美燕李淑静郑法伟路洪艳张平 School of Physics and Physical Engineering Qufu Normal UniversityQufu 273165China Center for Quantum Physics Key Laboratory of Advanced Optoelectronic Quantum Architecture and MeasurementSchool of PhysicsBeijing Institute of TechnologyBeijing 100081China Beijing Key Lab of Nanophotonics and Ultrafine Optoelectronic Systems School of PhysicsBeijing Institute of TechnologyBeijing 100081China College of Mathematics and Physics Beijing University of Chemical TechnologyBeijing 100029China Institute of Applied Physics and Computational Mathematics Beijing 100088China

Based on first-principles calculations, we systematically study the stacking energy and interlayer magnetic interaction of the heterobilayer composed of CrI_(3) and CrSe_(2) monolayers. It is found that the stacking order plays a crucial role in the interlayer magnetic coupling. Among all possible stacking structures, the AA-stacking is the most stable heterostructure, exhibiting interlayer antiferromagnetic interactions. Interestingly, the interlayer magnetic interaction can be effectively tuned by biaxial strain. A 4.3% compressive strain would result in a ferromagnetic interlayer interaction in all stacking orders. These results reveal the magnetic properties of CrI_(3)/CrSe_(2) heterostructure, which is expected to be applied to spintronic devices.
