| 1 | Federated Learning for 6G Communications:Challenges,Methods,and Future Directions显示文摘As the 5G communication networks are being widely deployed worldwide,both industry and academia have started to move beyond 5G and explore 6G communications.It is generally believed that 6G will be established on ubiquitous Artificial Intelligence(AI)to achieve data-driven Machine Learning(ML)solutions in heterogeneous and massive-scale networks.However,traditional ML techniques require centralized data collection and processing by a central server,which is becoming a bottleneck of large-scale implementation in daily life due to significantly increasing privacy concerns.Federated learning,as an emerging distributed AI approach with privacy preservation nature,is particularly attractive for various wireless applications,especially being treated as one of the vital solutions to achieve ubiquitous AI in 6G.In this article,we first introduce the integration of 6G and federated learning and provide potential federated learning applications for 6G.We then describe key technical challenges,the corresponding federated learning methods,and open problems for future research on federated learning in the context of 6G communications. | Yi Liu Xingliang Yuan Zehui Xiong Jiawen Kang Xiaofei Wang Dusit Niyato | 2020 | China Communications2020，17，9： | 21 |
| 2 | Inhibition of adipogenic differentiation by myostatin is alleviated by arginine supplementation in porcine-muscle-derived mesenchymal stem cells显示文摘Porcine mesenchymal stem cells in postnatal muscle have been demonstrated to differentiate into adipocytes.This increases adipocyte number and lipid accumulation,and is thought to be the origin of intramuscular fat.In this study,the effects of myostatin and arginine on adipogenic differentiation in mesenchymal stem cells derived from porcine muscle (pMDSCs) were investigated in vitro.Intracellular triglyceride levels were reduced by exogenous myostatin and increased by arginine supplementation or myostatin antibody (P<0.01).The inhibition of lipid accumulation by myostatin in pMDSCs was alleviated by arginine supplementation (P<0.01).Expression patterns of adipogenic transcription factors showed that exogenous myostatin suppressed PPARγ2 and aP2 expression (P<0.01),while supplemental arginine or myostatin antibody promoted ADD1 expression (P<0.01).Furthermore,compared with the addition of either myostatin protein or antibody alone,ADD1 and PPARδ expression were promoted by the combination of arginine and myostatin (P<0.01),and arginine combined with myostatin antibody promoted the expression of ADD1,PPAR,C/EBP,PPAR 2 and LPL in pMDSCs (P<0.05).These results suggest that myostatin inhibits adipogenesis in pMDSCs,and that this can be alleviated by arginine supplementation,at least in part,through promoting ADD1 and PPAR expression. | LEI HuLong YU Bing YANG XueRong LIU ZeHui HUANG ZhiQing MAO XiangBing TIAN Gang HE Jun HAN GuoQuan CHEN Hong MAO Qian CHEN DaiWen | 2011 | Science China(Life Sciences)2011，54，10： | 4 |
| 3 | On the State-dependent Switched Energy Functions of DFIG-based Wind Power Generation Systems显示文摘This paper proposes a novel state-dependent switched energy function(SdSEF)for general nonlinear autonomous systems,and constructs an SdSEF for doubly-fed induction generator(DFIG)-based wind power generation systems(WPGSs).Different from the conventional energy function,SdSEF is a piece-wise continuous function,and it satisfies the conditions of conventional energy functions on each of its continuous segments.SdSEF is designed to bridge the gap between the well-developed energy function theory and the description of system energy of complex nonlinear systems,such as power electronics converter systems.The stability criterion of nonlinear autonomous systems is investigated with SdSEF,and mathematical proof is presented.The SdSEF of a typical DFIGbased WPGS is simulated in the whole processes of a grid fault and fault recovery.Simulation results verify the negativeness of the derivative of each continuous segment of the SdSEF. | Yang Liu Zehui Lin Kaishun Xiahou Mengshi Li Q.H.Wu | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 4 |
| 4 | Dual-wavelength bidirectional pumped high-power Raman fiber laser显示文摘In this paper, we reported both the experimental demonstration and theoretical analysis of a Raman fiber laser based on a master oscillator–power amplifier configuration. The Raman fiber laser adopted the dual-wavelength bidirectional pumping configuration, utilizing 976 nm laser diodes and 1018 nm fiber lasers as the pump sources. A 60-m-long25/400 μm ytterbium-doped fiber was used to convert the power from 1070 to 1124 nm, realizing a maximum power output of 3.7 kW with a 3 dB spectral width of 6.8 nm. Moreover, we developed a multi-frequency model taking into consideration the Raman gain spectrum and amplified spontaneous emission. The calculated spectral broadening of both the forward and backward laser was in good agreement with the experimental results. Finally, a 1.5 kW, 1183 nm second-order Raman fiber laser was further experimentally demonstrated by the addition of a 70-m-long germaniumdoped passive fiber. | Zehui Wang Qirong Xiao Yusheng Huang Jiading Tian Dan Li Ping Yan Mali Gong | 2019 | High Power Laser Science and Engineering2019，7，1： | 4 |
| 5 | Fault-Tolerant Formation Tracking Control for Heterogeneous Multiagent Systems with Directed Topology显示文摘In this paper,the adaptive fault-tolerant formation tracking control problem for a set of heterogeneous unmanned aerial vehicle(UAV)and unmanned ground vehicle(UGV)systems with actuator loss of effectiveness faults is investigated.The cooperative fault-tolerant formation control strategy for UAV and UGV collaborative systems is classi-ed into the altitude consensus control scheme for follower UAVs and the position cooperative formation control scheme for all followers.The altitude consensus control algorithm is designed by utilizing backstepping control technique to drive all UAVs to a desired prede-ned height.Then,based on synchronization formation error information,the position cooperative formation control algorithm is proposed for all followers to reach the expected position and perform the desired formation con-guration.The adaptive fault estimation term is adopted in the designed fault-tolerant formation control algorithm to compensate for the actuator loss of effectiveness fault.Finally,a simulation example is proposed to reveal the validity of the designed cooperative formation tracking control scheme. | Jianye Gong Yajie Ma Bin Jiang Zehui Mao | 2021 | Guidance, Navigation and Control2021，1，1： | 3 |
| 6 | Effect of silica nanoparticles/poly(vinylidene fluoride-hexafluoropropylene) coated layers on the performance of polypropylene separator for lithium-ion batteries显示文摘In an effort to reduce thermal shrinkage and improve electrochemical performance of porous polypropylene(PP) separators for lithium-ion batteries, a new composite separator is developed by introducing ceramic coated layers on both sides of PP separator through a dip-coating process. The coated layers are comprised of heat-resistant and hydrophilic silica nanoparticles and polyvinylidene fluoride-hexafluoropropylene(PVDF-HFP) binders. Highly porous honeycomb structure is formed and the thickness of the layer is only about 700 nm. In comparison to the pristine PP separator, the composite separator shows significant reduction in thermal shrinkage and improvement in liquid electrolyte uptake and ionic conduction, which play an important role in improving cell performance such as discharge capacity, C-rate capability, cycle performance and coulombic efficiency. | Hongyu Liu Zehui Dai Jun Xu Baohua Guo Xiangming He | 2014 | Journal of Energy Chemistry2014，23，5： | 3 |
| 7 | The deubiquitinase OTUD1 inhibits colonic inflammation by suppressing RIPK1-mediated NF-κB signaling显示文摘The E3 ubiquitin ligase(E3)-mediated ubiquitination and deubiquitinase(DUB)-mediated deubiquitination processes are closely associated with the occurrence and development of colonic inflammation.Ovarian tumor deubiquitinase 1(OTUD1)is involved in immunoregulatory functions linked to infectious diseases.However,the effect of OTUD1 on intestinal immune responses during colonic inflammatory disorders such as inflammatory bowel disease(IBD)remains unclear.Here,we show that loss of OTUD1 in mice contributes to the pathogenesis of dextran sulfate sodium(DSS)-induced colitis via excessive release of proinflammatory cytokines.In addition,bone marrow transplantation experiments revealed that OTUD1 in hematopoietic cells plays a dominant role in protection against colitis.Mechanistically,OTUD1 physically interacts with receptor-interacting serine/threonine-protein kinase 1(RIPK1)and selectively cleaves K63-linked polyubiquitin chains from RIPK1 to inhibit the recruitment of NF-κB essential modulator(NEMO).Moreover,the expression of OTUD1 in mucosa samples from ulcerative colitis(UC)patients was lower than that in mucosa samples from healthy controls.Furthermore,we demonstrate that the UC-associated OTUD1 G430V mutation abolishes the ability of OTUD1 to inhibit RIPK1-mediated NF-κB activation and intestinal inflammation.Taken together,our study unveils a previously unexplored role of OTUD1 in moderating intestinal inflammation by inhibiting RIPK1-mediated NF-κB activation,suggesting that the OTUD1-RIPK1 axis could be a potential target for the treatment of IBD. | Bo Wu Lihua Qiang Yong Zhang Yesheng Fu Mengyuan Zhao Zehui Lei Zhe Lu Yan-Ge Wei Hongmiao Dai Yingwei Ge Mingqiu Liu Xuemei Zhou Zhiqiang Peng Hongchang Li Chun-Ping Cui Jing Wang Hui Zheng Cui Hua Liu Lingqiang Zhang | 2022 | Cellular & Molecular Immunology2022，19，2： | 3 |
| 8 | Similarity assessment for scientific workflow clustering and recommendation显示文摘This article proposes to identify and recommend scientific workflows for reuse and repurposing.Specifically, a scientific workflow is represented as a layer hierarchy that specifies the hierarchical relations between this workflow, its sub-workflows, and activities. Semantic similarity is calculated between layer hierarchies of workflows. A graph-skeleton based clustering technique is adopted for grouping layer hierarchies into clusters.Barycenters in each cluster are identified, which serve as core workflows in this cluster, for facilitating the cluster identification and workflow ranking and recommendation with respect to the requirement of scientists. | Zhangbing ZHOU Zehui CHENG Yueqin ZHU | 2016 | Science China(Information Sciences)2016，59，11： | 2 |
| 9 | The earthquake precursor detected in a granular medium and a proposed model for the propagation of precursive stress-strain signal显示文摘A way to detect the seismic precursor in granular medium is described and a model of propagation for precursive stress-strain signals is proposed.A strain sensor buried in a sandpit is used to measure a seismic precursor signal.The signal has been investigated and confirmed to originate from a specific earthquake.A comparison of simulated and experimental signals indicates that the signal results from the strain in the earth's strata.Based on the behavioral characteristics of granular materials,an analysis of why this method can be so sensitive to the seismic strain signal is undertaken and a model for the propagation of this stress-strain signal is proposed.The Earth's lithosphere is formed of tectonic plates,faults and fault gouges at their boundaries.In the case of the quasi-static mechanics of seismic precursory stress-strain propagation,the crustal lithosphere should be treated as a large-scale granular system.During a seismogenic event,accumulated force generates the stick-slip motion of adjacent tectonic plates and incrementally pushes blocks farther apart through stick-slip shift.The shear force released through this plate displacement causes soil compression deformation.The discrete properties of the sand in the sandpit lead to the sensitive response of the sensor to the deformation signal which enables it to detect the seismic precursor.From the analysis of the mechanism of the stress-strain propagation in the lithosphere,an explanation is found for the lack of signal detection by sensors installed in rocks.The principles and method presented in this paper provide a new technique for investigating seismic precursors to shallow-source earthquakes. | LU KunQuan HOU MeiYing WANG Qiang PENG Zheng SUN Wei SUN XiaoMing WANG YuYing TONG XiaoHui JIANG ZeHui LIU JiXing | 2011 | Chinese Science Bulletin2011，56，11： | 2 |
| 10 | Cloud Computing Based Optimal Driving for a Parallel Hybrid Electric Vehicle显示文摘A cloud computing based optimal driving method is proposed and its feasibility is validated through a real-world scenario simulation.Based on principles of vehicle dynamics,the driving optimization problem has been formulated into an optimal control problem constrained by traffic rules,directed at achieving lower equivalent fuel consumption and shorter travel time.In order to conveniently specify the constraints and facilitate the application of the dynamic programming(DP)algorithm,the driving optimization problem is transformed into spatial domain and discretized properly.Considering the heavy computational costs of the DP algorithm,a cloud computing based platform structure is proposed to solve the optimal driving problem in real-time.A case study is simulated based on a real-world traffic scenario in Matlab.Simulation results demonstrate that the cloud computing framework is promising toward realizing the real-time energy management for hybrid electric vehicles. | Jie Fan Yuan Zou Zehui Kong Ludger Heide | 2019 | Journal of Beijing Institute of Technology2019，28，1： | 2 |
| 11 | Grain production space reconstruction and land system function tradeoffs in China显示文摘Grain production space reconstruction referred to the changes in the quantity,quality and pattern of grain produc-tion space caused by functional tradeoffs and conflicts between grain production space,urban-rural development space,and ecological service space.Exploring tradeoffs between land system functions caused by grain produc-tion space reconstruction was particularly important for ensuring food security,promoting the construction of ecological civilization,and achieving sustainable development.Therefore,this study identified four relationships of land system functions during the process of grain production space reconstruction(1980-2018)in China by using Set Pair Analysis.Research results showed that the reconstruction of grain production space was achieved mainly through three pathways:Grain for Green,deforestation and reclamation,and urban expansion.Generally,ecological service had spatial negative correlation with grain production,economic development and population carrying capacity(P<0.01),but grain production,economic development and population carrying capacity were positively correlated with each other(P<0.01).In the process of grain production space reconstruction,eco-logical services and economic development,ecological services and population carrying capacity had all shown inverse synergies;there was a tradeoffbetween grain production and ecological services,a codirectional tradeoffbetween grain production and economic development,but a strong synergy between economic development and population carrying capacity.However,the functions of land systems only appeared as synergies or tradeoffs,and there were no inverse synergies and codirectional tradeoffs in the separate processes of Grain for Green,deforestation and reclamation,and urban expansion.It can be concluded that the relationships between land system functions were relatively simple in a single process,but it became complex and diverse when multiple processes were integrated for system analysis. | Fei Li Zhangxuan Qin Xiaolin Liu Zehui Chen Xiaoli Wei Qiumeng Zhang Min Lei | 2021 | Geography and Sustainability2021，2，1： | 2 |
| 12 | 6G-Enabled Edge AI for Metaverse:Challenges, Methods,and Future Research Directions显示文摘Sixth generation(6G)enabled edge intelligence opens up a new era of Internet of everything and makes it possible to interconnect people-devices-cloud anytime,anywhere.More and more next-generation wireless network smart service applications are changing our way of life and improving our quality of life.As the hottest new form of next-generation Internet applications,Metaverse is striving to connect billions of users and create a shared world where virtual and reality merge.However,limited by resources,computing power,and sensory devices,Metaverse is still far from realizing its full vision of immersion,materialization,and interoperability.To this end,this survey aims to realize this vision through the organic integration of 6G-enabled edge artificial intelligence(AI)and Metaverse.Specifically,we first introduce three new types of edge-Metaverse architectures that use 6G-enabled edge AI to solve resource and computing constraints in Metaverse.Then we summarize technical challenges that these architectures face in Metaverse and the existing solutions.Furthermore,we explore how the edge-Metaverse architecture technology helps Metaverse to interact and share digital data.Finally,we discuss future research directions to realize the true vision of Metaverse with 6G-enabled edge AI. | Luyi Chang Zhe Zhang Pei Li Shan Xi Wei Guo Yukang Shen Zehui Xiong Jiawen Kang Dusit Niyato Xiuquan Qiao Yi Wu | 2022 | Journal of Communications and Information Networks2022，7，2： | 2 |
| 13 | Heterosis for Seed Yield, Oil Content and Other Characters in Rapeseed (Brassica napus L.)显示文摘Nine inbred lines of rapeseed (Brassica napus L.) used as male were crossed to five recessive genetic male sterile (RGMS) lines used as female to produce 45 single crosses. The crosses, their parents and a check hybrid were tested at two locations during 2007 to 2008 for testing the performance and heterosis of hybrids for seed yield and other characters. Results showed that variations for seed yield, oil content, days to flowering and days to maturity were significant. Mean squares for hybrids were significant for all characters. High heterosis (–4.5%-88.3%), heterobeltiosis (–15.6%-81.1%) and standard heterosis (–34.8%-33.1%) were found for the seed yield. The highest heterosis and heterobeltiosis were found in the cross QH303-4A×1190. The highest standard heterosis was found in the cross Qianyou8A×Q034. Both positive and negative heterosis of single crosses were detected for the oil content. Small heterosis was found for days to flowering and days to maturity. Among parents, Ⅲ188, Ⅲ224, and Q034 were proved to be the superior for seed yield when used as parents in most of the hybrid combinations. 2365, Ⅲ224, and QH303-4AB were good for high oil content breeding. Ⅲ176, 2313 and Qianyou3AB were good for the early hybrid breeding. Total 11 hybrids yielded higher than 2 500 kg·hm -2 and also gave significantly positive heterosis, heterobeltiosis and standard heterosis. Among them, 10 crosses gave higher oil content than that of check. These crosses can be used in the future breeding program for the seed yield and the oil content. Two crosses including Qianyou3A ×Ⅲ224 and Qianyou3A×2313 can be used for the early breeding program. | HUANG Zesu LAOSUWAN Paisan MACHIKOWA Thitipom CHEN Zehui | 2010 | Journal of Northeast Agricultural University(English Edition)2010，17，1： | 2 |

| 16 | TRIM27 maintains gut homeostasis by promoting intestinal stem cell self-renewal显示文摘Dysregulation of gut homeostasis is associated with irritable bowel syndrome(IBS),a chronic functional gastrointestinal disorder affecting approximately 11.2%of the global population.The poorly understood pathogenesis of IBS has impeded its treatment.Here,we report that the E3 ubiquitin ligase tripartite motif-containing 27(TRIM27)is weakly expressed in IBS but highly expressed in inflammatory bowel disease(IBD),a frequent chronic organic gastrointestinal disorder.Accordingly,knockout of Trim27 in mice causes spontaneously occurring IBS-like symptoms,including increased visceral hyperalgesia and abnormal stool features,as observed in IBS patients.Mechanistically,TRIM27 stabilizesβ-catenin and thus activates Wnt/β-catenin signaling to promote intestinal stem cell(ISC)self-renewal.Consistent with these findings,Trim27 deficiency disrupts organoid formation,which is rescued by reintroducing TRIM27 orβ-catenin.Furthermore,Wnt/β-catenin signaling activator treatment ameliorates IBS symptoms by promoting ISC self-renewal.Taken together,these data indicate that TRIM27 is critical for maintaining gut homeostasis,suggesting that targeting the TRIM27/Wnt/β-catenin axis could be a potential treatment strategy for IBS.Our study also indicates that TRIM27 might serve as a potential biomarker for differentiating IBS from IBD. | Jing Wang Dongdong Zhao Zehui Lei Pupu Ge Zhe Lu Qiyao Chai Yong Zhang Lihua Qiang Yang Yu Xinwen Zhang Bingxi Li Shu Zhu Lingqiang Zhang Cui Hua Liu | 2023 | Cellular & Molecular Immunology2023，20，2： | 2 |
| 17 | Fault Ride-through Hybrid Controller for MMC-HVDC Transmission System via Switching Control Units Based on Bang-bang Funnel Controller显示文摘This paper proposes a fault ride-through hybrid controller(FRTHC)for modular multi-level converter based high-voltage direct current(MMC-HVDC)transmission systems.The FRTHC comprises four loops of cascading switching control units(SCUs).Each SCU switches between a bang-bang funnel controller(BBFC)and proportional-integral(PI)control loop according to a state-dependent switching law.The BBFC can utilize the full control capability of each control loop using three-value control signals with the maximum available magnitude.A state-dependent switching law is designed for each SCU to guarantee its structural stability.Simulation studies are conducted to verify the superior fault ride-through capability of the MMC-HVDC transmission system controlled by FRTHC,in comparison to that controlled by a vector controller(VC)and a VC with DC voltage droop control(VDRC). | Yang Liu Zehui Lin Chenying Xu Lei Wang | 2023 | Journal of Modern Power Systems and Clean Energy2023，11，2： | 1 |
| 18 | Transition metal doped mesoporous titania with a crystalline framework as catalysts for oxidation of p-bromotoluene to pbromobenzaldehyde显示文摘Transition metal M(M=Mn,Fe,Co,Ni,Cu,and Zn)doped mesoporous titania with a crystalline framework was employed as catalysts for the oxidation of p-bromotoluene(PBT)to p-bromobenzaldehyde(BBD)in acetic acid using aqueous hydrogen peroxide as oxidant.It was found that mesoporous TiO_(2) doped with those metals(Fe,Co and Ni)whose atomic radii are relatively smaller exhibited higher conversion rate of PBT.Among these catalysts,the Co/meso-TiO_(2) exhibited high substrate conversion and good product(p-bromobenzaldehyde)selectivity plus it can be reused once with almost the same activity.The effect of different Ti/Co(molar)ratio on the activities of Co/meso-TiO_(2) was also investigated. | Zehui YANG Lihui YIN Encai OU Yunan WANG Li PENG Jiaqiang WANG | 2008 | Frontiers of Chemical Science and Engineering2008，2，3： | 1 |
