为了进一步提升与蜂窝网络共享频谱资源的解码转发(decode-and-forward,DF)协作终端直通(device-to-device,D2D)网络的物理层安全(physical layer security,PLS)性能,提出了一种D2D发送端采用发射天线选择(transmit antenna selection,TAS)的修改转发(modify-and-forward,MF)协作D2D-蜂窝网络PLS模型。配备多根发射天线的D2D发送端采用TAS技术,选择使D2D发送端至MF中继节点链路信干噪比最大的天线发送信号;中继采用MF协议将解码得到的合法信息进行修改后再转发,以避免被动窃听者能够解码出此阶段发送的合法信息,从而改善了D2D网络的PLS性能。推导了MF协作D2D网络的安全中断概率、非零安全容量概率和渐近安全中断概率的解析表达式,并与DF协作D2D网络的PLS性能进行对比分析。数值计算与仿真结果表明,MF协作D2D网络的PLS性能优于DF协作D2D网络,并且增大D2D发送端的发射天线数量,可以增强D2D网络的PLS性能。

中继选择NOMA无线系统的物理层安全

电信科学 2024年第3期40卷 116-127页

作者：罗延翠李光球叶明珠高辉张亚娟杭州电子科技大学浙江杭州310018

针对解码转发协作非正交多址接入(non-orthogonal multiple access,NOMA)系统物理层安全(physical layer security,PLS)性能较差,以及在多窃听者场景下PLS性能恶化的问题,提出了一种采用修改转发(modify-and-forward,MF)协议的多中继选择NOMA无线系统PLS模型。利用高斯-切比雪夫正交定理推导了非合谋或合谋窃听场景下多中继选择MF-NOMA无线系统的安全中断概率和渐近安全中断概率的近似表达式。仿真结果验证了多中继选择MF-NOMA无线系统PLS性能分析的准确性。结果同时也表明中继数目越多或窃听者数目越少,多中继选择MF-NOMA无线系统的PLS性能越好;合谋窃听比非合谋窃听更不利于多中继MF-NOMA无线系统的安全传输。

目的:旨在探究巴戟天提取物(MoE)在地塞米松(Dex)诱导的肌少症小鼠中的治疗效果及可能作用机制。方法:首先利用网络药理学方法研究巴戟天的药效成分、重要靶点并富集通路,以预测MoE的作用机制。在动物实验中,50只KM小鼠随机分为5组(control、sarcopenia、MoE-H、MoE-M、MoE-L)。除control组,其他组皮下注射Dex 45 d诱导形成肌少症,3个治疗组同时经口给予不同剂量的MoE。实验过程中定期检测动物体重、运动能力(跑台和拉力计)和体成分。处死动物后计算后肢肌肉系数,进行组织学及相关基因表达检测。结果:网络药理学结果表明MoE可能通过上调IGF-1/AKT/mTOR信号通路来治疗肌少症。动物实验结果显示MoE显著逆转Dex导致的小鼠体重、肌肉系数的下降,提升运动能力,改善组织学病变,上调了IRS-1、mTOR、MFN2、OPA1、MYOD、MYOG等基因的表达,下调了Atrogin-1、MuRF-1、MSTN等基因的表达。结论:MoE对Dex引起的肌肉萎缩具有治疗作用,可改善肌肉组织学形态,其作用机制可能是激活IGF-1/AKT/mTOR通路。

Using the projected curve of surface mesh boundary as parameter domainborder, linear mapping parameterization with natural boundary is realized. A fast algorithm forleast squares fitting plane of vertices in the mesh boundary is proposed. After the mesh boundary isprojected onto the fitting plane, low-pass filtering is adopted to eliminate crossovers, sharpcorners and cavities in the projected curve and convert it into an eligible convex parameter domainboundary. In order to facilitate quantitative evaluations of parameterization schemes, threedistortion-measuring formulae are presented.

The object of the study was to develop a quick and reproducible accelerated in vitro release method to predict and deduce the function of the real time(37 °C) release for long acting PLGA microspheres. The method could be described in several steps. First, the release of the microspheres were studied using the sample and separate method at 37 °C with normal orbital shaking and elevated temperatures with magnetic stirring to further accelerate the release. Second, the most similar profile at elevated temperatures with the real time release was chosen with the help of the n value in the fitted Korsmeyer-Peppas Function. Third,the Weibull function and conversion ratio were used to deduce the function of real time release according to the chosen profile at elevated temperatures. The key point in this study was to provide a quick and precise method to predict the real time release for long acting progesterone PLGA microspheres. So the elevated temperatures coupled with magnetic stirring were used to accelerate the release further, and when there have many similar release profiles with the real time release at elevated temperatures, releasing time at elevated temperatures and the R2 of the final deduced function will be used to help choosing the most similar release profile with the real time release. Four different types of progesterone PLGA microspheres were used to verify the method, and all the deduced function correlated well with the real time releases, for R2 = 0.9912, 0.9781, 0.9918 and 0.9972, respectively.
