| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | Activation of the bitter taste sensor TRPM5 prevents high saltinduced cardiovascular dysfunction显示文摘High salt intake is a known risk factor of cardiovascular diseases. Our recent study demonstrated that long-term high salt intake impairs transient receptor potential channel M5(TRPM5)-mediated aversion to high salt concentrations, consequently promoting high salt intake and hypertension;however, it remains unknown whether TRPM5 activation ameliorates cardiovascular dysfunction. Herein we found that bitter melon extract(BME) and cucurbitacin E(CuE), a major compound in BME, lowered high salt-induced hypertension. Long-term BME intake significantly enhanced the aversion to high salt concentrations by upregulating TRPM5 expression and function, eventually decreasing excessive salt consumption in mice. Moreover, dietary BME ameliorated high salt-induced cardiovascular dysfunction and angiotensin II-induced hypertension in vivo. The mechanistic evidence demonstrated that dietary BME inhibited high salt-induced RhoA/Rho kinase pathway overactivation, leading to reduced phosphorylation levels of myosin light chain kinase and myosin phosphatase targeting subunit 1. Furthermore, CuE inhibited vasoconstriction by attenuating L-type Ca^(2+) channel-induced Ca^(2+) influx in vascular smooth muscle cells. To summarize, our findings indicate that dietary BME has a beneficial role in antagonizing excessive salt consumption and thus appears promising for the prevention of high salt-induced cardiovascular dysfunction. | Hao Wu Yuanting Cui Chengkang He Peng Gao Qiang Li Hexuan Zhang Yanli Jiang Yingru Hu Xiao Wei Zongshi Lu Tianyi Ma Daoyan Liu Zhiming Zhu | 2020 | Science China(Life Sciences)2020，63，11： | 2 |

| 5 | Parameter Estimation of a Spherical Top Inductively Coupled Plasma Source with Global Model显示文摘Using spatially averaged global model,we succeed in obtaining some plasma parameters for a low pressure inductively coupled plasma source of our laboratory.As far as the global balance is concerned,the models can give reasonable results of the parameters,such as the global electron temperature and the ion impacting energy,etc.It is found that the ion flow is hardly affected by the neutral gas pressure.Finally,the magnetic effects are calculated by means of the method.The magnetic field can play an important role to increase plasma density and ion current. | WU Hanming LI Ming CHEN Yunming WU Chengkang | 1995 | Chinese Physics Letters1995，12，5： | 0 |
| 6 | Bioinformatic analysis of human nuclear receptor nr5a2(hb1f) genomic sequence显示文摘We have cloned the cDNA of human nuclear receptor nr5a2(hb1f) gene and obtained its whole genomic sequence previously. In this work we carried out in-depth bioinformatic analysis on the genomic sequence of nr5a2(hb1f) gene. Sequence comparison and prediction algorithms implicated that there might be additional coding regions in the 210 kb genomic sequence besides known exons, especially in the two largest introns. Comparison of the structures of nr5a loci in different species revealed distinguishable conservation and apparent gene duplication during evolution. The remarkable conservation among promoters of zebrafish, mouse and human nr5a2 genes suggested that they would be regulated by the same transcription factors. | Zhang Chengkang Lin Wei Cai Yanning Dong Hui Li Mei Fu Gang Xie Youhua Huang M.Guyang Wang Yuan | 2002 | Chinese Science Bulletin2002，47，7： | 0 |
| 7 | Blockchain Based Secure Relay Scheme for Space-Terrestrial Integrated Networks显示文摘The future 6G networks will integrates space and terrestrial networks to realize a fully connected world with extensive collaboration.However,how to build trust between multiple parties is a difficult problem for secure cooperation without a reliable third-party.Blockchain is a promising technology to solve this problem by converting the trust between multi-parties to the trust to the common shared data.Several works have proposed to apply the incentive mechanism in blockchain to encourage effective cooperation,but how to evaluate the cooperation performance and avoid breach of contract is not discussed.In this paper,a secure relay scheme is proposed based on the consortium blockchain system composed by different operators.In particular,smart contract checks the integrity of the message based on RSA accumulator,and executes transactions automatically when the message is delivered successfully.Detailed procedures are introduced for both uplink and downlink relay.Implementation based on Hyperledger Fabric proves the effectiveness of the proposed scheme and shows that the complexity of the scheme is low enough for practical deployment. | Zhen Gao Jiuzhi Zhang Dongbin Zhang Ailing Wang Chengkang Pan Xin Li | 2023 | China Communications2023，20，5： | 0 |
