Cooperative Proactive Eavesdropping over Two-Hop Suspicious Communication Based on Reinforcement Learning

中国电子学会第十七届信息论学术年会

Intra - body communication(IBC) is a new,emerging,short - range and human body based communication methodology. It is a technique to network various devices on human body,by utilizing the conducting properties of human tissues,suitable for currently fast developing Body area network(BAN)/Body sensor network(BSN).IBC is believed to have advantages in power consumption, electromagnetic radiation,interference from external electromagnetic noise,security,and restriction in spectrum *** this article,the authors develop two models,which are analytical and empirical approaches,for comparing the performance and accuracy of IBC on a human *** in vivo experiment of five volunteers,both models basically match with the experimental result with equivalent circuit model superior than electromagnetic model in term of maximum error.

取欧洲鳗鲡(Anguilla anguilla)尾鳍进行体外培养,最终获得可连续传代的类纤维状的细胞系(欧洲鳗鲡尾鳍细胞系,European eel fin cell line,EEF)。探索不同传代比例对其生长增殖的影响。同时,以MTT法分析不同生长因子[碱性成纤维生长因子(FGF-basic)、肝细胞生长因子(HGF)、表皮生长因子(EGF)]对其增殖、形态的影响。结果显示:EEF增殖受上述生长因子调节作用很小,但是其形态却与FGF-basic的添加与否及其来源有很大关系。EEF细胞系的生长周期较目前所报道的欧洲鳗鲡细胞系快。染色体数目分析得出EEF的特征染色体数目为38条,这是首次基于体外培养细胞系的欧洲鳗鲡染色体数目分析。EEF的增殖、生长特性使之适宜于进一步开展鳗鲡病毒学、细胞生物学、基因组学、遗传学以及资源保护等方面的研究。
