1Reconfiguring wireless environments via intelligent surfaces for 6G:reflection,modulation,and security显示文摘The reconfigurable intelligent surface(RIS)has been recognized as an essential enabling technology for sixth-generation(6G)mobile communication networks.An RIS comprises a large number of small and low-cost reflecting elements whose parameters can be dynamically adjusted with a programmable controller.Each of these elements can effectively reflect a phase-shifted version of the incident electromagnetic wave.By configuring the wave phases in real time,the propagation environment of the information-bearing signals can be dynamically manipulated to enhance communication reliability,boost transmission rate,expand cellular coverage,and strengthen communication security.In this study,we provide an overview on RIS-assisted wireless communications.Specifically,we elaborate on the state-of-the-art enabling techniques for the RIS technology as well as their corresponding substantial benefits from the perspectives of RIS reflection and RIS modulation.With these benefits,we envision the integration of RISs into emerging applications for 6G.In addition,communication security is of unprecedented importance in future 6G networks with ubiquitous wireless services in multifarious verticals and areas.We highlight potential contributions of RISs to physical-layer security,in terms of secrecy rate and secrecy outage probability,exemplified by a typical case study from both theoretical and numerical aspects.Finally,we discuss challenges and opportunities on the deployment of RISs in practice to motivate future research.Jindan XU Chau YUEN Chongwen HUANG Naveed UL HASSAN George CALEXANDROPOULOS Marco DI RENZO Mérouane DEBBAH 2023Science China(Information Sciences)2023,66,3:3
2膳食硝酸盐通过减少交感神经过度激活的机制降低血管紧张素Ⅱ诱导的高血压大鼠的血压显示文摘几项实验和临床研究表明,膳食中添加硝酸盐可提高一氧化氮的生物利用度。在口腔中,共生细菌将硝酸盐还原成亚硝酸盐,其随后被吸收到循环中,通过酶系统还原为一氧化氮。已知增加硝酸盐-亚硝酸盐-一氧化氮途径可以改善心血管、肾脏和代谢功能,并且交感神经兴奋有助于疾病的进展,但是膳食硝酸盐对交感神经活动的潜在影响仍有待阐明。刘莉 叶鹏 ■ DD Cruz JC ■ A Zhuge Z Marques SM Naves LM Persson AEG Weitzberg E Lundberg JO Balarini CM Pedrino GR Braga VA ■ M 2019中华高血压杂志2019,0,3:2
3H^+,N^+和Ar^+离子束辐射诱导碳纳米结构的变化(英文)显示文摘在室温和高温下,以不同辐射剂量的H+、N+和Ar+离子辐照多壁碳纳米管和无定形碳纳米线。利用透射电镜和拉曼光谱研究多壁碳纳米管和无定形碳纳米线的结构变化及损伤。以70keV N+离子束辐射多壁碳纳米管在室温下可形成无定形碳纳米线。1000K下70keV的H+离子束照射导致无定形碳纳米线向金刚石结构转变。离子辐照多壁碳纳米管的有序程度足够高,70keV的N+和Ar+离子能够引起碳从多壁碳纳米管的剥落。离子辐射能够为缺陷的转化提供必需的动力学驱动力。A Ishaq Shahid Iqbal Naveed Ali A A Khurram A U Akrajas C F Dee Shahzad Naseem H M Rafique Yan Long 2013新型炭材料2013,28,2:2
