| 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 | 地震前亚失稳应力状态的识别--以5°拐折断层变形温度场演化的实验为例显示文摘识别亚失稳应力状态,研究其力学机理及与之相关物理场的演化特性,对于分析地震潜在危险性以及危险时段具有十分重要的理论意义和应用意义.在实验室,标本进入亚失稳态的标志是应力的加速释放.能否利用实验结果去鉴别自然条件下的地震?一个台站的观测数据仅代表该台站的应力状况,如何通过众多台站的观测数据了解区域应力状态是识别亚失稳态的关键问题.本文以拐折断层一次粘滑事件中不同变形阶段温度场的演化为例,试图寻找物理量在进入亚失稳状态的响应特征.文中分别讨论了应力积累阶段、失稳前应力-时间过程中偏离线性阶段、峰值后亚失稳阶段、失稳阶段和失稳后阶段的特点.研究结果显示断层的失稳错动是由断层各个部位独立活动向协同化活动的转化过程.失稳代表协同作用的完成.偏离线性阶段是应力释放的开始,也是协同作用的开始.在亚失稳阶段应力释放已占据优势,协同作用趋于完成.分析区域整体应力状态不能从单个台站出发,而是要从变形场的整体演化出发. | 马瑾 S I SHERMAN 郭彦双 | 2012 | 中国科学:地球科学2012，42，5： | 80 |

| 5 | Identification of meta-instable stress state based on experimental study of evolution of the temperature field during stick-slip instability on a 5° bending fault显示文摘Identification of the meta-instable stress state and study of its mechanism and evolution of relevant physical fields would be of great significance for determination of potential seismic risks and estimation of critical times. In laboratory experiments, that the specimen enters the meta-instable is marked by accelerated stress release. Could we use the experimental result to identify the earthquake in natural conditions? Because the observational data from one station can only reflect the stress state beneath this station, the key problem for identification of the meta-instability is how to recognize regional stress state through observational data from many stations. In this work, we choose the evolution of the temperature field over varied deformation stages during a stick-slip event on a 5 bending fault as an example, and attempt to find the response features of the physical quantity when the fault enters the meta-instable state. We discuss the characteristics of stages for the stress build-up, stress-time process deviating from linearity before instability, meta-instability, instability, and post-instability, respectively. The result shows that the fault instability slide is a conversion process from independent activities of each fault segment to synergism activity. The instability implies completion of the synergism. The stage deviating from linearity is the onset of stress release, and it is also the onset of the synergism. At the meta-instability stages, stress release becomes dominant, while the synergism tends to finish. Therefore, the analysis of the regional overall stress state should not start from individual stations, and instead it should begin with the evolution of the whole deformation field. | MA Jin S I SHERMAN GUO YanShuang | 2012 | Science China Earth Sciences2012，55，6： | 22 |
| 6 | Energy-Theft Detection Issues for Advanced Metering Infrastructure in Smart Grid显示文摘With the proliferation of smart grid research,the Advanced Metering Infrastructure(AMI) has become the first ubiquitous and fixed computing platform. However,due to the unique characteristics of AMI,such as complex network structure,resource-constrained smart meter,and privacy-sensitive data,it is an especially challenging issue to make AMI secure. Energy theft is one of the most important concerns related to the smart grid implementation. It is estimated that utility companies lose more than $25 billion every year due to energy theft around the world. To address this challenge,in this paper,we discuss the background of AMI and identify major security requirements that AMI should meet. Specifically,an attack tree based threat model is first presented to illustrate the energy-theft behaviors in AMI. Then,we summarize the current AMI energy-theft detection schemes into three categories,i.e.,classification-based,state estimation-based,and game theory-based ones,and make extensive comparisons and discussions on them. In order to provide a deep understanding of security vulnerabilities and solutions in AMI and shed light on future research directions,we also explore some open challenges and potential solutions for energy-theft detection. | Rong Jiang Rongxing Lu Ye Wang Jun Luo Changxiang Shen Xuemin(Sherman) Shen | 2014 | Tsinghua Science and Technology2014，19，2： | 22 |
| 7 | Spatial patterns of plant diversity and communities in Alpine ecosystems of the Hengduan Mountains, northwest Yunnan, China显示文摘Aims Conduct a quantitative,but rapid,regional-level assessment of the alpine flora across northwest Yunnan(NWY)to provide a broadbased understanding of local and regional patterns of the composition,diversity and health of alpine ecosystems across NWY.Methods A stratified random sampling design was employed to select sites across the different mountain ranges of NWY.Vegetation was sampled by stratifying each site by the three major alpine vegetation community types:meadow,dwarf shrub and scree.Two 50-m transects were randomly located within each community type at each sampling site with 101-m^(2) subplots systematically placed along each transect.Environmental variables were recorded at each transect.Multivariate analyses were used to classify the major plant community assemblages and link community patterns to environmental and habitat variables.Important Findings Forb species richness varied from 19 to 105 species per site(21 sites total)with an average of 59 species per site(60 m^(2) sampled per site).Most species were patchily distributed with narrow distributions and/or small population sizes;over half the species occurred at only one or two sites.Distinct species assemblages were identified in the meadow vegetation that was strongly aggregated by geographic location suggesting the presence of distinct phytogeographic zones of the meadow alpine flora.Elevation and geographic location were the dominant environmental gradients underlying the variations in species composition.Jaccard’s coefficient of similarity averaged only 10%among sites indicating there was little similarity in the alpine flora across the region.The alpine vegetation is highly heterogeneous across the complex landscape of the Hengduan Mountains of NWY.Conservation strategies need to take into account the large geographic differences in the flora to maximize protection of biodiversity. | Ruth Sherman Renee Mullen Li Haomin Fang Zhendong Wang Yi | 2008 | Journal of Plant Ecology2008，1，2： | 20 |
| 8 | Internet of Vehicles in Big Data Era显示文摘As the rapid development of automotive telematics,modern vehicles are expected to be connected through heterogeneous radio access technologies and are able to exchange massive information with their surrounding environment. By significantly expanding the network scale and conducting both real-time and long-term information processing, the traditional Vehicular AdHoc Networks(VANETs) are evolving to the Internet of Vehicles(Io V), which promises efficient and intelligent prospect for the future transportation system. On the other hand, vehicles are not only consuming but also generating a huge amount and enormous types of data, which is referred to as Big Data. In this article, we first investigate the relationship between Io V and big data in vehicular environment, mainly on how Io V supports the transmission, storage, computing of the big data, and how Io V benefits from big data in terms of Io V characterization,performance evaluation and big data assisted communication protocol design. We then investigate the application of Io V big data in autonomous vehicles. Finally, the emerging issues of the big data enabled Io V are discussed. | Wenchao Xu Haibo Zhou Nan Cheng Feng Lyu Weisen Shi Jiayin Chen Xuemin (Sherman) Shen | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，1： | 19 |
| 9 | Role of Sonic Hedgehog signaling during progression from inflammation to cancer in the stomach显示文摘Despite advances in treatment and the declining incidence,gastric cancer remains the second leading cause of cancer-related deaths in the world.Understanding the progression from inflammation to cancer in the stomach is crucial in the development of novel therapies and strategies for treating this disease.Chronic inflammation of the stomach is typically caused by Helicobacter pylori(H.pylori)and resulting lesions may lead to gastric cancer.During the progression from inflammation to cancer,the stomach epithelium changes with evidence of the disruption of normal epithelial cell differentiation and infiltrating inflammatory cells.Coincident with the development of atrophic gastritis and metaplasia,is the loss of the gastric morphogen Sonic Hedgehog(Shh).Given its critical role as a regulator of gastric tissue homeostasis,the disruption of Shh expression during inflammation correlates with the loss of normal epithelial cell differentiation,but this has only recently been rigorously tested in vivo using a unique mouse model of targeted gastric Shh deletion.While pre-neoplastic lesions such as atrophic gastritis and in-testinal metaplasia are associated with the loss of Shh within the acid-secreting glands of the stomach,there is a clear link between elevated Shh and signaling to gastric cancers.The current review focuses on the effects of aberrant Shh expression and its role in the development of gastric cancer,specifically in response to H.pylori infection. | Alexander E Sherman Yana Zavros | 2011 | World Journal of Gastrointestinal Pathophysiology2011，2，6： | 14 |
| 10 | Cooperative Vehicular Content Distribution in Edge Computing Assisted 5G-VANET显示文摘By leveraging the 5G enabled vehicular ad hoc network(5G-VANET), it is widely recognized that connected vehicles have the potentials to improve road safety, transportation intelligence and provide in-vehicle entertainment experience. However, many enabling applications in 5G-VANET rely on the efficient content sharing among mobile vehicles, which is a very challenging issue due to the extremely large data volume, rapid topology change, and unbalanced traffic. In this paper, we investigate content prefetching and distribution in 5G-VANET. We first introduce an edge computing based hierarchical architecture for efficient distribution of large-volume vehicular data. We then propose a multi-place multi-factor prefetching scheme to meet the rapid topology change and unbalanced traffic. The content requests of vehicles can be served by neighbors, which can improve the sharing efficiency and alleviate the burden of networks. Furthermore, we use a graph theory based approach to solve the content distribution by transforming it into a maximum weighted independent set problem. Finally, the proposed scheme is evaluated with a greedy transmission strategy to demonstrate its efficiency. | Guiyang Luo Quan Yuan Haibo Zhou Nan Cheng Zhihan Liu Fangchun Yang Xuemin (Sherman) Shen | 2018 | China Communications2018，15，7： | 13 |
| 11 | Chinese herbal medicine for COVID-19: Current evidence with systematic review and meta-analysis显示文摘Background: There is currently no drug or therapy that cures COVID-19, a highly contagious and life-threatening disease.Objective: This systematic review and meta-analysis summarized contemporary studies that report the use of Chinese herbal medicine(CHM) to treat COVID-19.Search strategy: Six electronic databases(PubMed/MEDLINE, Cochrane Library, ScienceDirect, Google Scholar, Wanfang Data and China National Knowledge Infrastructure) were searched from their beginning to May 15, 2020 with the following search terms: traditional Chinese medicine, Chinese medicine,Chinese herbal medicine, COVID-19, new coronavirus pneumonia, SARS-CoV-2, and randomized controlled trial.Inclusion criteria: Randomized controlled trials(RCTs) from peer-reviewed journals and non-reviewed publications were included. Further, included RCTs had a control group that was given standard care(SC;such as conventional Western medicine treatments or routine medical care), and a treatment group that was given SC plus CHM.Data extraction and analysis: Two evaluators screened and collected literature independently;information on participants, study design, interventions, follow-up and adverse events were extracted, and risk of bias was assessed. The primary outcomes included scores that represented changes in symptoms and signs over the course of treatment. Secondary outcomes included the level of inflammatory markers, improvement of pneumonia confirmed by computed tomography(CT), and adverse events. Dichotomous data were expressed as risk ratio or hazard ratio with 95% confidence interval(CI);where time-to-event analysis was used, outcomes were expressed as odds ratio with 95% CI. Continuous data were expressed as difference in means(MD) with 95% CI, and standardized mean difference(SMD) was used when different outcome scales were pooled.Results: Seven original studies, comprising a total of 732 adults, were included in this meta-analysis.Compared to SC alone, CHM plus SC had a superior effect on the change of symptom and sign score(-1.30 by SMD, 95% CI [-2.43, -0.16];3 studies;n = 261, P = 0.03), on inflammatory marker C-reactive protein(CRP, mg/L;-11.82 by MD, 95% CI [-17.95, -5.69];5 studies;n = 325, P = 0.0002),on number of patients with improved lung CT scans(1.34 by risk ratio, 95% CI [1.19, 1.51];4 studies;n = 489, P < 0.00001). No significant adverse events were recorded in the included RCTs.Conclusion: Current evidence shows that CHM, as an adjunct treatment with standard care, helps to improve treatment outcomes in COVID-19 cases. | Arthur Yin Fan Sherman Gu Sarah Faggert Alemi Research Group for Evidence-based Chinese Medicine | 2020 | Journal of Integrative Medicine2020，18，5： | 12 |
| 12 | Reconfigurable intelligent surfaces for smart wireless environments:channel estimation,system design and applications in 6G networks显示文摘Reconfigurable intelligent surface(RIS),one of the key enablers for the sixth-generation(6G)mobile communication networks,is considered by designers to smartly reconfigure the wireless propagation environment in a controllable and programmable manner.Specifically,an RIS consists of a large number of low-cost and passive reflective elements(REs)without radio frequency chains.The system gain of RIS wireless systems can be achieved by adjusting the phase shifts and amplitudes of the REs so that the desired signals can be added constructively at the receiver.However,an RIS typically has limited signal processing capability and cannot perform active transmitting/receiving in general,which leads to new challenges in the physical layer design of RIS wireless systems.In this paper,we provide an overview of the RIS-aided wireless systems,including the reflection principle,channel estimation,and system design.In particular,two types of emerging RIS systems are considered:RIS-aided wireless communications(RAWC)and RISbased information transmission(RBIT),where the RIS plays the role of the reflector and the transmitter,respectively.We also envision the potential applications of RIS in 6G networks. | Ying-Chang LIANG Jie CHEN Ruizhe LONG Zhen-Qing HE Xianqi LIN Chenlu HUANG Shilin LIU Xuemin(Sherman)SHEN Marco DI RENZO | 2021 | Science China(Information Sciences)2021，64，10： | 12 |

| 18 | Lubiprostone used with polyethylene glycol in diabetic patients enhances colonoscopy preparation quality显示文摘AIM: To assess the additive effect of lubiprostone on the quality of colon preparation in diabetics given single-dosed polyethylene glycol electrolyte(PEG)for colonoscopy.METHODS:This was an investigator-initiated,singlecenter,single-blinded prospective trial comparing the efficacy of L+PEG to PEG alone on colon preparation quality in diabetics undergoing screening colonoscopy.The study was approved by our institution’s IRB.The PEG was given as a single-dose to address patientcompliance concerns voiced by our IRB with splitdosing.All patients received only clear liquids the day prior to colonoscopy.Experimental group(Grp L)received PEG+1 dose L 2 h prior to and 2 h after PEG completion.Control group(Grp C)received only PEG the evening prior to the colonoscopy.Patients were randomly assigned to one of the 2 groups.The endoscopist was blinded to which colon prep was given and all colonoscopies were complete.Upon colonoscopy completion,the endoscopist rated the colon prep-quality by a validated 5-point Likert scale(1-excellent to 5-inadequate).RESULTS:Sixty patients were enrolled in the study;30 Grp L and 30 Grp C.Overall,patients were excluded due to study non-completion in 12(41%)Grp L and 5(17%) Grp C,P=0.04.Average colon preparation score Grp L =2.47 and Grp C=3.00,P=0.09.Although this was not statistically significant,there was a trend towards improved colon prep in Grp L.Statistical significance may have been achieved if completion rates had been similar between both study groups.CONCLUSION:Use of 2-L capsules with PEG resulted in a trend towards improved colon prep over PEG alone in diabetic patients when given as a single-dose regimen. | Erika Grigg Moonkyung C Schubert Joshua Hall Fadi Rahhal Dimple Raina Subbaramiah Sridhar Sherman M Chamberlain | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，7： | 5 |
| 19 | Mechanical responses, texture and microstructural evolution of high purity aluminum deformed by equal channel angular pressing显示文摘Ultrafine-grained(UFG) high purity aluminum exhibits a variety of attractive mechanical properties and special deformation behavior. Equal channel angular pressing(ECAP) process can be used to easily and effectively refine metals. The microstructure and microtexture evolutions and grain boundary characteristics of the high purity aluminum(99.998%) processed by ECAP at room temperature are investigated by means of TEM and EBSD. The results indicate that the shear deformation resistance increases with repeated EACP passes, and equiaxed grains with an average size of 0.9 μm in diameter are formed after five passes. Although the orientations distribution of grains tends to evolve toward random orientations, and microtextures(80°, 35°, 0°),(40°, 75°, 45°) and(0°, 85°, 45°) peak in the sample after five passes. The grain boundaries in UFG aluminum are high-angle geometrically necessary boundaries. It is suggested that the continuous dynamic recrystallization is responsible for the formation of ultrafine grains in high purity aluminum. Microstructure evolution in the high purity aluminum during ECAP is proposed. | 汪冰峰 孙杰英 邹金佃 VINCENT Sherman 李娟 | 2015 | Journal of Central South University2015，22，10： | 4 |
