面向B5G及6G无线通信系统的高速无线信息传输,本文研究了智能超表面辅助毫米波(RIS-mmWave)系统的高效能波束训练及信道估计方法。特别地,基于RIS-mmWave波束管理及有效信道获取的内生关联性,本文创新性地提出一种机器学习辅助的RIS-mmWave系统高效波束训练及信道估计方法。具体而言,在第一阶段,设计了一种新颖的半监督学习模型,实现位置信息辅助的在线快速波束训练,并且免估计地直接获取粗略角度域信息以驱动精细化信道估计;在第二阶段中,提出半监督学习辅助的压缩感知级联信道估计算法,利用半监督学习模型直接输出的粗略角度域信息驱动块正交匹配追踪算法进行信道估计。仿真结果表明,所提波束训练及信道估计方法在系统开销和信道估计误差等方面的性能均优于代表性参考方案。

RIS辅助自组织网络可以改善复杂电磁环境下的网络性能,然而RIS无源特性导致其易受攻击,攻击者可恶意操纵RIS相位来恶化端到端传输性能甚至中断链路。鉴于攻击者可有针对性的攻击正在反射传输信号的RIS,且RIS不具备信号处理能力,无法通过密钥等方式对抗攻击,因此提出了基于物理层符号集特征的攻击感知方案来识别RIS攻击,并在RIS攻击导致链路中断时设计面向RIS攻击的路由恢复策略。仿真结果表明,所提方案能够有效识别RIS攻击并规避由RIS攻击导致的链路中断,对比基于断点续传的路由恢复策略,所提方案能够减少路由恢复时间,保障端到端时延。

顽固性失眠作为一种慢性重症睡眠障碍,其睡眠时间不足和质量低下的特点严重影响患者身心健康。现代医学治疗顽固性失眠主要以苯二氮卓受体激动剂、抗抑郁等口服药物治疗为主,然长期服用药物后所产生的不良反应、依赖性让患者痛苦不堪;因此顽固性失眠的治疗迫切需要一种安全有效的方法。总结贾成文教授以针刺结合口服中药治疗顽固性失眠的经验,为临床治疗此病提供一种安全性更高、不良反应少患者易于接受的新方法。贾教授总结出顽固性失眠病位在心,主要责之肝、胆两脏;认为“心、肝、之阳燥动而心神不安或肝失疏泄、肝气郁结,胆气失和,肝胆互扰”是发病病机,治疗以“平肝潜阳,养心安神”为法,具体以“头皮神八针”联合晚清医家费伯雄方甲乙归藏汤加减,内服中药外以针刺,身心兼调。贾教授基于肝胆论治疗顽固性失眠而获效验,为临床治疗顽固性失眠提供了宝贵的经验,值得推广。

The Tarim Basin is the largest, oil-bearing, superimposed basin in the northwest of China. The evolution and tectonic properties of the initial Tarim Basin have been hotly disputed and remain enigmatic. The Neoproterozoic basin is covered by a vast desert and a huge-thickness of sedimentary strata, has experienced multiple tectonic movements, had a low signal to noise ratios(SNRs) of deep seismic reflection data, all of which have posed critical obstacles to research. We analysed four field outcrops, 18 wells distributed throughout the basin, 27 reprocessed seismic reflection profiles with higher SNRs across the basin and many ancillary local 2D and 3D profiles and aeromagnetic data. We found about 20 normal fault-controlled rifting depressions of the Cryogenian and Ediacaran scattered throughout the basin, which developed on the Precambrian metamorphic and crystalline basement. The structural framework is clearly different from that of the overlying Phanerozoic. The rifting depressions consist of mainly half grabens, symmetrical troughs and horst-grabens. From the northeast to southwest of the basin,they are divided into three rifting depression groups with the WNW, ENE, and NW-trends that are mainly controlled by normal faults. The maximum thicknesses of the strata are up to 4100 m. From the Cryogenian to Ediacaran, most of the main inherited faults to active and eventually ceased at the end of the Ediacaran or Early Cambrian, while subsidence centres appeared and migrated eastward along the faults. They revealed that the different parts of the Tarim continental block were in NNE-SSWoriented and NNW-SSE-oriented extensional paleo-stress fields(relative to the present) during the Neoproterozoic, and were accompanied by clockwise shearing. According to the analysis of the activities of syn-sedimentary faults, filling sediments,magmatic events, and coordination with aeromagnetic anomalies, the tectonic properties of the fault depressions are different and are primari
