1Towards 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 2021Science China(Information Sciences)2021,64,1:122

3Effect of artificial aeration on the performance of vertical-flow constructed wetland treating heavily polluted river water显示文摘Three lab-scale vertical-flow constructed wetlands(VFCWs),including the non-aerated(NA),intermittently aerated(IA) and continuously aerated(CA) ones,were operated at different hydraulic loading rates(HLRs) to evaluate the effect of artificial aeration on the treatment efficiency of heavily polluted river water.Results indicated that artificial aeration increased the dissolved oxygen(DO) concentrations in IA and CA,which significantly favored the removal of organic matter and NH 4 +-N.The DO grads caused by intermittent aeration formed aerobic and anoxic regions in IA and thus promoted the removal of total nitrogen(TN).Although the removal efficiencies of COD Cr,NH 4 +-N and TN in the three VFCWs all decreased with an increase in HLR,artificial aeration enhanced the reactor resistance to the fluctuation of pollutant loadings.The maximal removal efficiencies of COD Cr,NH 4 +-N and total phosphorus(TP)(i.e.,81%,87% and 37%,respectively) were observed in CA at 19 cm/day HLR,while the maximal TN removal(i.e.,57%) was achieved in IA.Although the improvement of artificial aeration on TP removal was limited,this study has demonstrated the feasibility of applying artificial aeration to VFCWs treating polluted river water,particularly at a high HLR.Huiyu Dong Zhimin Qiang Tinggang Li Hui Jin Weidong Chen 2012Journal of Environmental Sciences2012,24,4:38
4China National Medical Products Administration approval summary:anlotinib for the treatment of advanced non-small cell lung cancer after two lines of chemotherapy显示文摘Background:On May 8,2018,the China National Medical Products Administration(NMPA)approved anlotinib,an orally administered anti-angiogenesis inhibitor,for the treatment of patients with advanced non-small cell lung can-cer(NSCLC)who have progressed after treatment with two or more lines of prior systemic chemotherapy.Main body of the abstract:China NMPA reviewed and inspected a regional double-blinded,placebo-controlled,Phase III trial comparing the overall survival(OS)of NSCLC patients between the anlotinib and placebo arms.A total of 437 patients were randomized(2:1)to receive either anlotinib(n=294)or placebo(n=143)once daily on a 2-week on and 1-week off schedule.Patients with epidermal growth factor receptor(EGFR)or activating anaplastic lymphoma kinase(ALK)genomic tumor aberrations should have disease progression on NMPA-approved therapy.Anlotinib is the first NMPA-approved drug for patients with advanced NSCLC who have progressed on at least two lines of prior systemic chemotherapies in China.The approval was based on a statistically and clinically significant improvement in median OS with anlotinib(9.46 months)compared with placebo[6.37 months;hazard ratio(HR])=0.70,95%confidence interval(CI)=0.55-0.89;two-sided log-rank P=0.002].The confirmed objective response rate(ORR)was 9.2%in the anlotinib arm and 0.7%in the placebo arm.The median duration of response(DoR)was 4.83 months,with a 95%CI of 3.31-6.97 months.The toxicity profile of anlotinib was consistent with that of known anti-angiogenesis inhibitors.Common adverse drug reactions(ADRs)in anlotinib-treated patients included hypertension(67.4%),hand-foot syndrome(43.9%),hemoptysis(14.0%),thyroid stimulating hormone(TSH)elevation(46.6%),and corrected QT interval(QTc)prolongation(26.2%).Short conclusion:Anlotinib demonstrated a clinically significant OS prolongation as a novel therapeutic option for advanced or metastatic NSCLC following at least two lines of chemotherapy.Ming Zhou Xiaoyuan Chen Hong Zhang Lin Xia Xin Tong Limin Zou Ruimin Hao Jianhong Pan Xiao Zhao Dongmei Chen Yuanyuan Song Yueli Qi Ling Tang Zhifang Liu Rong Gao Yuankai Shi Zhimin Yang 2019Cancer Communications2019,39,1:35
5Shifts of the Kuroshio axis over the last 20 000 years显示文摘Core 255 from the southern Okinawa Trough was selected to monitor the shift of the Kuroshio axis over the last 20 000 years. During the last glacial maximum the Kuroshio axis had ever shifted outside the Okinawa Trough. It entered the Okinawa Trough again at about 6 500 a BP, leading to abrupt increase of sedimentation rate, distinctly coarser sediment and remarkably increased abundance of foraminiferal indicators of the Kuroshio in the core. But, during about 4 000-3 000 a BP the abundance of the Kuroshio indicator Pulleniatina obliquiloculata sharply decreased again, indicating that the Kuroshio axis had ever shifted easterly for a short period or the Kuroshio was weakened and that moment.Jian Zhimin Y.

6The ChinaMAP analytics of deep whole genome sequences in 10,588 individuals显示文摘Metabolic diseases are the most common and rapidly growing health issues worldwide.The massive population-based human genetics is crucial for the precise prevention and intervention of metabolic disorders.The China Metabolic Analytics Project(ChinaMAP)is based on cohort studies across diverse regions and ethnic groups with metabolic phenotypic data in China.Here,we describe the centralized analysis of the deep whole genome sequencing data and the genetic bases of metabolic traits in 10,588 individuals from the ChinaMAP.The frequency spectrum of variants,population structure,pathogenic variants and novel genomic characteristics were analyzed.The individual genetic evaluations of Mendelian diseases,nutrition and drug metabolism,and traits of blood glucose and BMI were integrated.Our study establishes a large-scale and deep resource for the genetics of East Asians and provides opportunities for novel genetic discoveries of metabolic characteristics and disorders.Yanan Cao Lin Li Min Xu Zhimin Feng Xiaohui Sun Jieli Lu Yu Xu Peina Du Tiange Wang Ruying Hu Zhen Ye Lixin Shi Xulei Tang Li Yan Zhengnan Gao Gang Chen Yinfei Zhang Lulu Chen Guang Ning Yufang Bi Weiqing Wang The ChinaMAP Consortium 2020Cell Research2020,30,9:20
7The M_S7.1 Yushu earthquake surface rupture and large historical earthquakes on the Garzê-Yushu Fault显示文摘As revealed by field investigations,the co-seismic surface rupture zone of the 2010 MS7.1 Yushu earthquake,Qinghai is a characteristic sinistral strike-slip feature consisting of three distinct sinistral primary ruptures,with an overall strike of 310°-320° and a total length of 31 km.In addition,an approximately 2-km-long en-echelon tensile fissure zone was found east of Longbao Town;if this site is taken as the north end of the rupture zone,then the rupture had a total length of ~51 km.The surface rupture zone is composed of a series of fissures arranged in an en-echelon or alternating relationship between compressive bulges and tensile fissures,with a measured maximum horizontal displacement of 1.8 m.The surface rupture zone extends along the mapped Garzê-Yushu Fault,which implicates it as the seismogenic fault for this earthquake.Historically,a few earthquakes with a magnitude of about 7 have occurred along the fault,and additionally traces of paleoearthquakes are evident that characterize the short-period recurrence interval of large earthquakes here.Similar to the seismogenic process of the 2008 Wenchuan earthquake,the Yushu earthquake is also due to the stress accumulation and release on the block boundaries resulting from the eastward expansion of Qinghai-Tibet Plateau.However,in contrast with the Wenchuan earthquake,the Yushu earthquake had a sinistral strike-slip mechanism resulting from the uneven eastward extrusion of the Baryan Har and Sichuan-Yunnan fault blocks.CHEN LiChun WANG Hu RAN YongKang SUN XinZhe SU GuiWu WANG Ji TAN XiBin LI ZhiMin ZHANG XiaoQing 2010Chinese Science Bulletin2010,55,31:17
8Simultaneous determination of three classes of antibiotics in the suspended solids of swine wastewater by ultrasonic extraction,solid-phase extraction and liquid chromatography-mass spectrometry显示文摘This work describes a systematic approach to the development of a method for simultaneous determination of three classes of veterinary antibiotics in the suspended solids (SS) of swine wastewater,including five sulfonamides,three tetracyclines and one macrolide (tiamulin).The entire procedures for sample pretreatment,ultrasonic extraction (USE),solid-phase extraction (SPE),and liquid chromatography-mass spectrometry (LC-MS) quantification were examined and optimized.The recovery efficiencies were found to be 76%-104% for sulfonamides,81%-112% for tetracyclines,and 51%-64% for tiamulin at three spiking levels.The intra-day and inter-day precisions,as expressed by the relative standard deviation (RSD),were below 17%.The method detection limits (MDLs) were between 0.14 and 7.14 μg/kg,depending on a specific antibiotic studied.The developed method was applied to field samples collected from three concentrated swine feeding plants located in Beijing,Shanghai and Shandong province of China.All the investigated antibiotics were detected in both SS and liquid phase of swine wastewater,with partition coefficients (logK d) ranging from 0.49 to 2.30.This study demonstrates that the SS can not be ignored when determining the concentrations of antibiotics in swine wastewater.Xun Pan Zhimin Qiang Weiwei Ben Meixue Chen 2011Journal of Environmental Sciences2011,23,10:16

10Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu 2019Cancer Biology & Medicine2019,16,1:14
11Quaternary biogenic opal records in the South China Sea: Linkages to East Asian monsoon, global ice volume and orbital forcing显示文摘Particulate fluxes investigated in the central South China Sea (SCS) during 1993―1996 indicate that opal flux can be used to show primary productivity change, which provides a foundation for tracing the evolutionary relationship between the surface productivity and East Asian monsoon in the SCS during the late Quaternary glacial and interglacial periods. Based on the studies of opal % and their mass accumulation rates (MAR) at the six sites recovered from the SCS during the “Resolution” ODP Leg 184 and “Sonne” 95 cruise of the Sino-Germany cooperation, opal % and their MARs increased evidently in the northern sites since 470―900 ka, and they enhanced and reduced, respectively, during the glacial and interglacial periods. Whereas they increased obviously in the southern sites since 420―450 ka, and they augmented and declined, respectively, during the interglacial and glacial periods. The vari- ability in opal % and their MARs in the late Quaternary glacial cyclicity indicate the “seesaw” pattern of surface productivity in the SCS. The winter monsoon intensified during the glacial periods, surface productivity increased and decreased, respectively, in the northern and southern SCS. The summer monsoon strengthened during the interglacial periods, surface productivity increased and decreased, respectively, in the southern and northern SCS. The cross spectral analyses between the opal % in the northern and southern SCS during the Quaternary and global ice volume (δ 18O) and orbital forcing (ETP) indicate that the East Asian winter and summer monsoons could be ascribed to the different drive mechanisms. On the orbital time scale, the global ice volume change could be a dominant factor for the winter monsoon intension and temporal variations. As compared with the winter monsoon, the correlative summer solar radiation with the obliquity and precession in the Northern Hemisphere could be a mostly controlling factor for the summer monsoon intension and temporal variations.WANG RuJian JIAN ZhiMin XIAO WenShen TIAN Jun LI JianRu CHEN RongHua ZHENG YuLong CHEN JianFang 2007Science China Earth Sciences2007,50,5:9
12Study on methane selective catalytic reduction of NO on Pt/Ce_(0.67)Zr_(0.33)O_2 and its application显示文摘Monolithic catalysts of Pt/La-Al2O3 and Pt/Ce0.67Zr0.33O2 were prepared to investigate methane selective catalytic reduction (SCR) of NO. The results indicate that Pt/Ce0.67Zr0.33O2 shows high activity and both NO and CH4 can be converted completely at 450 °C. Meanwhile, NO and CH4 can be converted completely when there exists excess oxygen. The Pt/Ce0.67Zr0.33O2 catalyst were further investigated by using methane as reducing agent to SCR NO in a novel equipment which combined the CH4 selective catalytic reduction of NO with methane combustion. The result shows that the catalyst is high active and the novel equipment is very effective. The conversion of NO is above 92% under the conditions used in this work. The prepared burner and catalysts have great potential for application.Zhimin Liu Kangcai Wang Xiaoyu Zhang Jianli Wang Hongyan Cao Maochu Gong Yaoqiang Chen 2009Journal of Natural Gas Chemistry2009,18,1:9

20The critical rate of horizontal wells in bottom-water reservoirs with an impermeable barrier显示文摘Barrier impacts on water cut and critical rate of horizontal wells in bottom water-drive reservoirs have been recognized but not investigated quantitatively. Considering the existence of impermeable barriers in oil formations, this paper developed a horizontal well flow model and obtained mathematical equations for the critical rate when water cresting forms in bottom-water reservoirs. The result shows that the barrier increases the critical rate and delays water breakthrough. Further study of the barrier size and location shows that increases in the barrier size and the distance between the barrier and oil-water contact lead to higher critical rates. The critical rate gradually approaches a constant as the barrier size increases. The case study shows the method presented here can be used to predict the critical rate in a bottom-water reservoir and applied to investigate the water cresting behavior of horizontal wells.Yue Ping Du Zhimin Chen Xiaofan Liang Baosheng 2012Petroleum Science2012,9,2:6
