    A Game-Theoretic Response Strategy for Coordinator Attack in Wireless Sensor Networks by Jianhua Liu, Guangxue Yue, Shigen Shen, Huiliang Shang, Hongjie Li

    Published 2014-01-01
    “…In this paper, we propose an adaptive coordinator selection algorithm using game and fuzzy logic aiming at both minimizing the average number of hops and maximizing network lifetime. The proposed game model consists of two interrelated formulations: a stochastic game for dynamic defense and a best response policy using evolutionary game formulation for coordinator selection. …”

    CAF: Cluster Algorithm and A-Star with Fuzzy Approach for Lifetime Enhancement in Wireless Sensor Networks by Yali Yuan, Caihong Li, Yi Yang, Xiangliang Zhang, Lian Li

    Published 2014-01-01
    “…Secondly, the combined methods of fuzzy inference and A-star algorithm are adopted, taking into account the factors such as the remaining power, the minimum hops, and the traffic numbers of nodes. Simulation results demonstrate that the proposed method has significant effectiveness in terms of balancing energy consumption as well as maximizing the network lifetime by comparing the performance of the A-star and fuzzy (AF) approach, cluster and fuzzy (CF)method, cluster and A-star (CA)method, A-star method, and SEP algorithm under the same routing criteria.…”

    High-performance solid-state proton gating membranes based on two-dimensional hydrogen-bonded organic framework composites by Dandan Lei, Yixiang Wang, Qixiang Zhang, Shuqi Wang, Lei Jiang, Zhen Zhang

    Published 2025-01-01
    “…Density functional theory calculations reveal that the reversible formation and disruption of humidity-induced water bridges within the frameworks facilitates the switching of proton transport mode from the adsorption site hopping to the Grotthuss mechanism. This transition, coupled with the introduction of bacterial cellulose to enhance desorption/adsorption of water clusters, enables us to achieve a superior proton gating ratio of up to 5740, surpassing state-of-the-art solid-state gating devices. …”

    Three-dimensional mapping of the altermagnetic spin splitting in CrSb by Guowei Yang, Zhanghuan Li, Sai Yang, Jiyuan Li, Hao Zheng, Weifan Zhu, Ze Pan, Yifu Xu, Saizheng Cao, Wenxuan Zhao, Anupam Jana, Jiawen Zhang, Mao Ye, Yu Song, Lun-Hui Hu, Lexian Yang, Jun Fujii, Ivana Vobornik, Ming Shi, Huiqiu Yuan, Yongjun Zhang, Yuanfeng Xu, Yang Liu

    Published 2025-02-01
    “…Tight-binding model analysis indicates that the large altermagnetic splitting arises from strong third-nearest-neighbor hopping mediated by Sb ions. The large band/spin splitting near Fermi level in metallic CrSb, together with its high T N (up to 705 K) and simple spin configuration, paves the way for exploring emergent phenomena and spintronic applications based on altermagnets.…”

    Behaviours preceding suicides at railway and underground locations: a multimethodological qualitative approach by Lisa Marzano, Jay-Marie Mackenzie, Jo Borrill, Emily Hawkins, Bob Fields, Ian Kruger, Ian Noonan

    Published 2018-04-01
    “…Data were gathered from several sources, including interviews with individuals who survived a rail suicide attempt (n=9), CCTV footage of individuals who died by rail suicide (n=16) and qualitative survey data providing views from rail staff (n=79).Results Our research suggests that there are several behaviours that people may carry out before a suicide or suicide attempt at a rail location, including station hopping and platform switching, limiting contact with others, positioning themselves at the end of the track where the train/tube approaches, allowing trains to pass by and carrying out repetitive behaviours.Conclusions There are several behaviours that may be identifiable in the moments leading up to a suicide or suicide attempt on the railways which may present opportunities for intervention. …”
