| 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 |

| 3 | Occurrence and distribution of antibiotic resistance genes in the sediments of the East China Sea bays显示文摘The coastal area of the East China Sea has experienced rapid urbanization and industrialization in China since 1980 s, resulting in severe pollution of its environments.Antibiotic resistance genes(ARGs) are regarded as a kind of emerging pollutant with potential high risk. The sediment samples were collected from Hangzhou Bay(HB),Xiangshan Bay(XB), and Taizhou Bay(TB) to investigate the spatial occurrence and distribution of 27 ARGs and class I integron–integrase gene(intI1) in the coastal area of the East China Sea. The PCR results showed the frequent presence of 11 ARGs and intI1 in the sediments of the three bays. The qPCR results further showed that sulfonamide resistance was the most prevalent ARG type and antibiotic target replacement and protection were the most important resistance mechanisms in the sediments. Regarding the subtype of ARGs, sulI, tetW, and dfrA13 were the most abundant ARGs, in which sulI was higher in TB(based on both the absolute and relative abundances) and dfrA13 was higher in HB(based on the relative abundances). The network analysis revealed that intI1 had significant correlations with tetC, sulI, sulII, and blaPSE-1. Oil was the key connected factor, which had positive connections with sulI, sulII, and blaPSE-1. In addition, the joint effect of heavy metals and nutrients & organic pollutants might be crucial for the fate of ARGs in the coastal sediments. | Jiayu Chen Zhiguo Su Tianjiao Dai Bei Huang Qinglin Mu Yongming Zhang Donghui Wen | 2019 | Journal of Environmental Sciences2019，31，7： | 13 |
| 4 | Multi-omics analyses of 398 foxtail millet accessions reveal genomic regions associated with domestication,metabolite traits,and antiinflammatory effects显示文摘Foxtail millet(Setaria italica),which was domesticatedfromthewild speciesgreenfoxtail(Setaria viridis),isa richsource of phytonutrientsfor humans.To evaluate how breeding changed themetabolome offoxtail millet grains,we generated and analyzed the datasets encompassing the genomes,transcriptomes,metabolomes,and anti-inflammatory indices from 398 foxtail millet accessions.We identified hundreds of common variants that influence numerous secondary metabolites.We observed tremendous differences in natural variations of the metabolites and their underlying genetic architectures between distinct sub-groups of foxtail millet.Furthermore,we found that the selection of the gene alleles associated with yellow grains led to altered profiles of metabolites such as carotenoids and endogenous phytohormones.Using CRiSPR-mediated genome editing wevalidated the function of PHYTOENE SYNTHASE1(PSY1)gene in affecting milletgrain colorand quality.Interestingly,our in vitro cell inflammation assays showed that 83 metabolites in millet grains have anti-inflammatory effects.Taken together,ourmulti-omics study illustrates how the breeding history of foxtail millet has shaped its metabolite profile.The datasets we generated in this study also provide important resources for further understanding how millet grain quality is affected by different metabolites,laying the foundations for future millet genetic research and metabolome-assisted improvement. | Xukai Li Jianhua Gao Jingyi Song Kai Guo Siyu Hou Xingchun Wang Qiang He Yanyan Zhang Yakun Zhang Yulu Yang Jiaoyan Tang Hailang Wang Staffan Persson Mingquan Huang Lishuai Xu Linlin Zhong Dongqin Li Yongming Liu Hua Wu Xianmin Diao Peng Chen Xiaowen Wang Yuanhuai Han | 2022 | Molecular Plant2022，15，8： | 8 |
| 5 | Adsorption and desorption characteristics of diphenylarsenicals in two contrasting soils显示文摘Diphenylarsinic acid(DPAA) is formed during the leakage of aromatic arsenic chemical weapons in soils,is persistent in nature,and results in arsenic contamination in the field.The adsorption and desorption characteristics of DPAA were investigated in two typical Chinese soils,an Acrisol(a variable-charge soil) and a Phaeozem(a constant-charge soil).Their thermodynamics and some of the factors influencing them(i.e.,initial pH value,ionic strength and phosphate) were also evaluated using the batch method in order to understand the environmental fate of DPAA in soils.The results indicate that Acrisol had a stronger adsorption capacity for DPAA than Phaeozem.Soil DPAA adsorption was a spontaneous and endothermic process and the amount of DPAA adsorbed was affected significantly by variation in soil pH and phosphate.In contrast,soil organic matter and ionic strength had no significant effect on adsorption.This suggests that DPAA adsorption may be due to specific adsorption on soil mineral surfaces.Therefore,monitoring the fate of DPAA in soils is recommended in areas contaminated by leakage from chemical weapons. | Anan Wang Shixin Li Ying Teng Wuxin Liu Longhua Wu Haibo Zhang Yujuan Huang Yongming Luo Peter Christie | 2013 | Journal of Environmental Sciences2013，25，6： | 8 |
| 6 | Whole genome sequencing of 10K patients with acute ischaemic stroke or transient ischaemic attack: design, methods and baseline patient characteristics显示文摘Background and purpose Stroke is the second leading cause of death worldwide and the leading cause of mortality and long-term disability in China,but its underlying risk genes and pathways are far from being comprehensively understood.We here describe the design and methods of whole genome sequencing(WGS)for 10914 patients with acute ischaemic stroke or transient ischaemic attack from the Third China National Stroke Registry(CNSR-III).Methods Baseline clinical characteristics of the included patients in this study were reported.DNA was extracted from white blood cells of participants.Libraries are constructed using qualified DNA,and WGS is conducted on BGISEQ-500 platform.The average depth is intended to be greater than 30×for each subject.Afterwards,Sentieon software is applied to process the sequencing data under the Genome Analysis Toolkit best practice guidance to call genotypes of single nucleotide variants(SNVs)and insertion-deletions.For each included subject,21 fingerprint SNVs are genotyped by MassARRAY assays to verify that DNA sample and sequencing data originate from the same individual.The copy number variations and structural variations are also called for each patient.All of the genetic variants are annotated and predicted by bioinformatics software or by reviewing public databases.Results The average age of the included 10914 patients was 62.2±11.3 years,and 31.4%patients were women.Most of the baseline clinical characteristics of the 10914 and the excluded patients were balanced.Conclusions The WGS data together with abundant clinical and imaging data of CNSR-III could provide opportunity to elucidate the molecular mechanisms and discover novel therapeutic targets for stroke. | Si Cheng Zhe Xu Yang Liu Jinxi Lin Yong Jiang Yilong Wang Xia Meng Anxin Wang Xinying Huang Zhimin Wang Guohua Chen Songdi Wu Zhengchang Jia Yongming Chen Xuerong Qiu Jun Wu Binbin Song Weizhong Ji Zhongping An Wenjun Xue Lili Zhao Yu Geng Hongyan Li Hao Li Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 8 |
| 7 | High mobility group box 1 protein (HMGB1) as an immune-modulating factor for polarization of human T lymphocytes显示文摘Objective This study was performed to investigate the effect of high mobility group box-1 protein (HMGB1) on immune function of human T lymphocytes in vitro and explore its potential role in cell-mediated immune dysfunction. Methods Fresh blood was obtained from healthy adult volunteers and peripheral blood mononuclear cells (PBMCs) were isolated, then rhHMGB1 was added to PBMCs. Four-color flow cytometric (FCM) analysis was used for the measurement of intracellular cytokine including interleukin IL-4 and interferon IFN- ? ELISA kits were employed for the determination of IL-2 and sIL-2R protein levels in cell culture supernatants. Results (1) Different stimulating time and dosage of rhHMGB1 did not alter the number of IFN- αpositive cells (Th1). rhHMGB1 stimulation provoked a dose-dependent and time-dependent increase in Th2 subset and decrease in ratio of Th1 to Th2. (2) Compared with the untreated cells, when the cells were coincubated with rhHMGB1 (10-100ng/ml) for 12 hrs, protein release of IL-2 and sIL-2R were significantly up-regulated. At 48 hrs, in contrast, protein production was relatively lower in cells after exposure to 100-1000 ng/ ml rhHMGB1. Conclusions These findings demonstrated that HMGB1 has a dual influence on immune functions of human T lymphocytes. | Lifeng Huang Yongming Yao Haidong Meng Xiaodong Zhao Ning Dong Yan Yu | 2008 | Journal of Geriatric Cardiology2008，5，2： | 6 |
| 8 | Energy Optimization for Cellular-Connected Multi-UAV Mobile Edge Computing Systems with Multi-Access Schemes显示文摘In this paper,a cellular-connected unmanned aerial vehicle(UAV)mobile edge computing system is studied where several UAVs are associated to a terrestrial base station(TBS)for computation offloading.To compute the large amount of data bits,a part of computation task is migrated to TBS and the other part is locally handled at UAVs.Our goal is to minimize the total energy consumption of all UAVs by jointly adjusting the bit allocation,power allocation,resource partitioning as well as UAV trajectory under TBS’s energy budget.For deeply comprehending the impact of multi-UAV access strategy on the system performance,four access schemes in the uplink transmission is considered,i.e.,time division multiple access,orthogonal frequency division multiple access,one-by-one access and non-orthogonal multiple access.The involved problems under different access schemes are all formulated in non-convex forms,which are difficult to be tackled optimally.To solve this class of problem,the successive convex approximation technique is employed to obtain the suboptimal solutions.The numerical results show that the proposed scheme save significant energy consumption compared with the benchmark schemes. | Meng Hua Yongming Huang Yi Wang Qingqing Wu Haibo Dai Lyuxi Yang | 2018 | Journal of Communications and Information Networks2018，3，4： | 6 |
| 9 | Outage Probability Minimization for Low-Altitude UAV-Enabled Full-Duplex Mobile Relaying Systems显示文摘In this paper, a novel unmanned aerial vehicle(UAV)-enabled full duplex decode-and-forward(DF) technique is used in mobile relaying system. Compared with conventional static relaying, mobile relaying provides more degree of freedom for experiencing better channel conditions and further improving the system reliable performance. The source and relay transmit power as well as relay trajectory are jointly optimized for sum outage probability minimization in mobile relaying system. Due to the non-convex nature of the original problem, block coordinate decent optimization techniques are employed to decompose it into two sub-problems, which leads to an efficient iterative algorithm. Specifically, for the pre-determined relay trajectory, the optimal transmit power of source and relay are obtained by solving Karush-Kuhn-Tucker(KKT) conditions. For the given source/relay power allocation, the optimal UAV trajectory is obtained by solving dual problem. Based on the two steps, an iterative algorithm is proposed to jointly optimize source/relay power allocation and UAV trajectory alternately. Numerical results show the performance gain of our proposed scheme. | Meng Hua Yi Wang Zhengming Zhang Chunguo Li Yongming Huang Luxi Yang | 2018 | China Communications2018，15，5： | 5 |
| 10 | Sequential injection spectrophotometric determination of nanomolar nitrite in seawater by on-line preconcentration with HLB cartridge显示文摘The unstable state of nitrite results in its very low concentration in seawater,which is below the limit of detection(LOD) of conventional techniques of analysis. Some sensitivity-enhanced methods have been proposed for the determination of nitrite at nanomolar level to illustrate the role of nitrite in the marine nitrogen cycle. However,most of previous reports are not widely accepted,because of their complexity and cost equipment or intensive labor requirement. In this study,a simple automatic system for the determination of nanomolar level nitrite using on-line preconcentration with spectrophotometric detection was described. An Oasis HLB cartridge was adopted to quantitatively enrich the pink-colored azo compound,formed from nitrite via Griess reaction. The cartridge was rinsed with water and ethanol(volume fraction is 55%,the same below) ,in turn,then eluted by an eluent containing 50% ethanol and 0.25 M(mol/dm 3 ) H 2 SO 4,and determined at 543 nm with a 2 cm path-length flow cell. Under the optimized experimental conditions,the calibration curve showed a good linearity in the range of 1.4-85.7 nM,and the LOD(3σ) was estimated to be 0.5 nM. The relative standard deviations of 7 measurements were 4.0% and 1.0% for the samples spiked at 7.1 and 28.6 nM,respectively. The recoveries for the different natural water samples were between 92.2%-108.4%. Each HLB cartridge could be reused for at least 50 times. As compared with other SPE methods,the advantages of this method included the free of interference from salinity variation and less sample consuming. The results of the application of the proposed method to natural water showed good agreement with liquid waveguide capillary cell detection method. | ZHANG Min YUAN Dongxing HUANG Yongming CHEN Guohe ZHANG Zhen | 2010 | Acta Oceanologica Sinica2010，29，1： | 4 |
| 11 | Blockchain-enabled wireless communications:a new paradigm towards 6G显示文摘With the deployment of fifth-generation(5 G)wireless networks worldwide,research on sixth-generation(6 G)wireless communications has commenced.It is expected that 6 G networks can accommodate numerous heterogeneous devices and infrastructures with enhanced efficiency and security over diverse,e.g.spectrum,computing and storage,resources.However,this goal is impeded by a number of trust-related issues that are often neglected in network designs.Blockchain,as an innovative and revolutionary technology that has arisen in the recent decade,provides a promising solution.Building on its nature of decentralization,transparency,anonymity,immutability,traceability and resiliency,blockchain can establish cooperative trust among separate network entities and facilitate,e.g.efficient resource sharing,trusted data interaction,secure access control,privacy protection,and tracing,certification and supervision functionalities for wireless networks,thus presenting a new paradigm towards 6 G.This paper is dedicated to blockchain-enabled wireless communication technologies.We first provide a brief introduction to the fundamentals of blockchain,and then we conduct a comprehensive investigation of the most recent efforts in incorporating blockchain into wireless communications from several aspects.Importantly,we further propose a unified framework of the blockchain radio access network(B-RAN)as a trustworthy and secure paradigm for 6 G networking by utilizing blockchain technologies with enhanced efficiency and security.The critical elements of B-RAN,such as consensus mechanisms,smart contract,trustworthy access,mathematical modeling,cross-network sharing,data tracking and auditing and intelligent networking,are elaborated.We also provide the prototype design of B-RAN along with the latest experimental results. | Jiaheng Wang Xintong Ling Yuwei Le Yongming Huang Xiaohu You | 2021 | National Science Review2021，8，9： | 4 |
| 12 | Design and Implementation of a TDD-Based 128-Antenna Massive MIMO Prototype System显示文摘Owing to the dramatic mobile IP growth,the emerging Internet of Things,and cloud-based applications,wireless networking is witnessing a paradigm shift.By fully exploiting spatial degrees of freedom,massive multiple-input-multiple-output(MIMO) systems promise significant gains in data rates and link reliability.Although the research community has recognized the theoretical benefits of these systems,building the hardware of such complex systems is a challenge in practice.This paper presents a time division duplex(TDD)-based 128-antenna massive MIMO prototype system from theory to reality.First,an analytical signal model is provided to facilitate the setup of a feasible massive MIMO prototype system.Second,a link-level simulation consistent with practical TDDbased massive MIMO systems is conducted to guide and validate the massive MIMO system design.We design and implement the TDDbased 128-antenna massive MIMO prototype system with the guidelines obtained from the link-level simulation.Uplink real-time video transmission and downlink data transmission under the configuration of multiple single-antenna users are achieved.Comparisons withstate-of-the-art prototypes demonstrate the advantages of the proposed system in terms of antenna number,bandwidth,latency,and throughput.The proposed system is also equipped with scalability,which makes the system applicable to a wide range of massive scenarios. | Xi Yang Wenjun Lu Ning Wang Karl Nieman Chao-Kai Wen Chuan Zhang Shi Jin Xiaomin Mu Ian Wong Yongming Huang Xiaohu You | 2017 | China Communications2017，14，12： | 3 |
| 13 | Refinement of Methodology for Cadmium Determination in Soil Micro-Arthropod Tissues显示文摘Highly precise and reliable determination of heavy metals in soil micro-arthropod tissues remains a challenge because of the small size of the animals and their typical low abundance in metal-contaminated agricultural soils. The present study sought to develop a method for cadmium(Cd) determination in soil micro-arthropods by optimizing the sample digestion procedure, reducing sample weight, modifying sample pre-treatment and validating the methodology with field samples. The optimized digestion conditions comprised a sample mass of 50–150 μg, digestion reagent of nitric acid:hydrogen peroxide(3:1), digestion temperature of 105℃,digestion period of 3 h and digestion volume of 30 μL. Defecation of the standard Collembola Folsomia candida(92 h) and the indigenous Collembola Onychiurus yodai(42 h) and ultrasonic cleaning of F. candida increased the accuracy of Cd determination.The recovery of Cd using the refined procedure was 98.9% and the limits of detection and quantification were 0.002 and 0.008 μg L^(-1), respectively. The within-batch precision values were < 3%. The Cd concentrations in the tissues of the Collembola Isotoma sp.collected from a range of metal-contaminated fields determined by the improved method were consistent with the Cd concentrations in the field soils. The results indicate that the optimized method can be used for more accurate or reliable determination of Cd concentrations in soil micro-arthropod tissues. | ZHU Dong KE Xin WU Longhua HUANG Yujuan Peter CHRISTIE LUO Yongming | 2017 | Pedosphere2017，27，3： | 3 |
| 14 | A novel artificial noise aided security scheme to resist blind source separation attacks显示文摘In this paper,we discuss the physical layer security from a new angle of view and propose a novel approach to resist some attacks in signal processing perspective.The scenario considered in this paper is that the eavesdropper has the similar channel performance compared to the legitimate receiver.We design the optimal artificial noise(AN)to resist the attacks of the eavesdropper who uses the blind source separation(BSS)technology to reconstruct the secret information.For speech signals,the optimal AN is obtained by minimizing the maximum of the correlation coefficients between the source signal and the received signals at Eve and the correlation coefficients between the source signal and separated results of BSS.For binary phase shift keying(BPSK)signals,we maximize the minimum bit error rates(BERs)of the separated signals and the obtained signals at Eve.Moreover,we consider the AN design from the point of breaking the BSS conditions,and propose a method by changing the correlation coefficient randomly.The simulation results show that the AN we proposed has better performance than that of the white Gaussian AN to resist the BSS attacks for both speech signals and the BPSK signals. | Guyue Li Aiqun Hu Yongming Huang | 2014 | Chinese Science Bulletin2014，59，32： | 3 |

| 17 | Non-isothermal crystallization kinetics of wood-flour/polypropylene composites in the presence of b-nucleating agent显示文摘The influence of aryl amide compounds(TMB)as b-nucleating agents, on the non-isothermal crystallization of a wood-flour/polypropylene composite(WF/PP)prepared by compression molding was investigated by wide-angle X-ray diffraction and differential scanning calorimetry. TMB was proved to be an effective b-crystalline nucleating agent for WF/PP. The DSC data showed that the crystallization peak temperature(Tp) increased and the half-time(t1/2) decreased with the addition of TMB.Three theoretical models were used to analyze the nonisothermal crystallization process. The modified Avrami method and Mo method successfully explained the nonisothermal crystallization behavior of PP and its composites. Their activation energies for non-isothermal crystallization were determined basing on the Kissinger method. | Lang Huang Haigang Wang Weihong Wang Qingwen Wang Yongming Song | 2016 | Journal of Forestry Research2016，27，4： | 2 |
| 18 | Synthesis of novel hierarchical porous polymers with a nanowire-interconnected network structure from core-shell polymer nanoobjects显示文摘Design and fabrication of the micro/nanostructures of the network units is a critical issue for porous nanonetwork structured materials. Significant progress has been attained in construction of the network units with zero-dimensional spherical shapes.However, owing to the limitations of synthetic methods, construction of porous building blocks in one dimension featuring high aspect ratios for porous nanonetwork structured polymer(PNSP) remains largely unexplored. Here we present the successful design and preparation of PNSP with a novel type of one-dimensional network unit, i.e., microporous heterogeneous nanowire. Well-defined core-shell polymer nanoobjects prepared from a gelable block copolymer, poly(3-(triethoxysilyl)propyl methacrylate)-block-polystyrene are employed as building blocks, and facilely transformed into PNSP via hypercrosslinking of polystyrene shell. The as-prepared PNSP exhibits unique three-dimensional hierarchical nanonetwork morphologies with large surface area. These findings could provide a new avenue for fabrication of unique well-defined PNSP, and thus generate valuable breakthroughs in many applications. | yeru liang yingbo ruan junlong huang bo peng chen-yang liu ruowen fu mingqiu zhang yongming chen dingcai wu | 2017 | Science China Chemistry2017，60，8： | 2 |
