| 1 | Interaction of In-wheel Permanent Magnet Synchronous Motor with Tire Dynamics显示文摘Drive wheel systems combined with the in-wheel permanent magnet synchronous motor(I-PMSM) and the tire are highly electromechanical-coupled. However, the deformation dynamics of this system, which may influence the system performance, is neglected in most existing literatures. For this reason, a deformable tire and a detailed I-PMSM are modeled using Matlab/Simulink. Furthermore, the influence of tire/road contact interface is accurately described by the non-linear relaxation length-based model and magic formula pragmatic model. The drive wheel model used in this paper is closer to that of a real tire in contrast to the rigid tire model which is widely used. Based on the near-precise model mentioned above, the sensitivity of the dynamic tire and I-PMSM parameters to the relative error of slip ratio estimation is analyzed. Additionally, the torsional and longitudinal vibrations of the drive wheel are presented both in time and frequency domains when a quarter vehicle is started under conditions of a specific torque curve, which includes an abrupt torque change from 30 N·m to 200 N·m. The parameters sensitivity on drive wheel vibrations is also studied, and the parameters include the mass distribution ratio of tire, the tire torsional stiffness, the tire damping coefficient, and the hysteresis band of the PMSM current control algorithm. Finally, different target torque curves are compared in the simulation, which shows that the estimation error of the slip ratio gets violent, and the longitudinal force includes more fluctuation components with the increasing change rate of the torque. This paper analyzes the influence of the drive wheel deformation on the vehicle dynamic control, and provides useful information regarding the electric vehicle traction control. | SONG Ziyou LI Jianqiu WEI Yintao XU Liangfei OUYANG Minggao | 2015 | Chinese Journal of Mechanical Engineering2015,28,3: | 7 |
| 2 | miR-145 improves metabolic inflammatory disease through multiple pathways显示文摘Chronic inflammation plays a pivotal role in insulin resistance and type 2 diabetes,yet the mechanisms are not completely understood.Here,we demonstrated that serum LPS levels were significantly higher in newly diagnosed diabetic patients than in normal control.miR-145 level in peripheral blood mononuclear cells decreased in type 2 diabetics.LPS repressed the transcription of miR-143/145 cluster and decreased miR-145 levels.Attenuation of miR-145 activity by anti-miR-145 triggered liver inflammation and increased serum chemokines in C57BL/6 J mice.Conversely,lentivirus-mediated miR-145 overexpression inhibited macrophage infiltration,reduced body weight,and improved glucose metabolism in db/db mice.And miR-145 overexpression markedly reduced plaque size in the aorta in ApoE−/−mice.Both OPG and KLF5 were targets of miR-145.miR-145 repressed cell proliferation and induced apoptosis partially by targeting OPG and KLF5.miR-145 also suppressed NF-κB activation by targeting OPG and KLF5.Our findings provide an association of the environment with the progress of metabolic disorders.Increasing miR-145 may be a new potential therapeutic strategy in preventing and treating metabolic diseases such as type 2 diabetes and atherosclerosis. | Min He Nan Wu Man Cheong Leong Weiwei Zhang Zi Ye Rumei Li Jinyang Huang Zhaoyun Zhang Lianxi Li Xiao Yao Wenbai Zhou Naijia Liu Zhihong Yang Xuehong Dong Yintao Li Lili Chen Qin Li Xuanchun Wang Jie Wen Xiaolong Zhao Bin Lu Yehong Yang Qinghua Wang Renming Hu | 2020 | Journal of Molecular Cell Biology2020,12,2: | 7 |
| 3 | Comprehensive multivariate grey incidence degree based on principal component analysis显示文摘To overcome the too fine-grained granularity problem of multivariate grey incidence analysis and to explore the comprehensive incidence analysis model, three multivariate grey incidences degree models based on principal component analysis(PCA) are proposed. Firstly, the PCA method is introduced to extract the feature sequences of a behavioral matrix. Then, the grey incidence analysis between two behavioral matrices is transformed into the similarity and nearness measure between their feature sequences. Based on the classic grey incidence analysis theory, absolute and relative incidence degree models for feature sequences are constructed, and a comprehensive grey incidence model is proposed. Furthermore, the properties of models are researched. It proves that the proposed models satisfy the properties of translation invariance, multiple transformation invariance,and axioms of the grey incidence analysis, respectively. Finally, a case is studied. The results illustrate that the model is effective than other multivariate grey incidence analysis models. | Ke Zhang Yintao Zhang Pinpin Qu | 2014 | Journal of Systems Engineering and Electronics2014,25,5: | 5 |
| 4 | Influence of Tire Dynamics on Slip Ratio Estimation of Independent Driving Wheel System显示文摘The independent driving wheel system, which is composed of in-wheel permanent magnet synchronous motor(I-PMSM) and tire, is more convenient to estimate the slip ratio because the rotary speed of the rotor can be accurately measured. However, the ring speed of the tire ring doesn't equal to the rotor speed considering the tire deformation. For this reason, a deformable tire and a detailed I-PMSM are modeled by using Matlab/Simulink. Moreover, the tire/road contact interface(a slippery road) is accurately described by the non-linear relaxation length-based model and the Magic Formula pragmatic model. Based on the relatively accurate model, the error of slip ratio estimated by the rotor rotary speed is analyzed in both time and frequency domains when a quarter car is started by the I-PMSM with a definite target torque input curve. In addition, the natural frequencies(NFs) of the driving wheel system with variable parameters are illustrated to present the relationship between the slip ratio estimation error and the NF. According to this relationship, a low-pass filter, whose cut-off frequency corresponds to the NF, is proposed to eliminate the error in the estimated slip ratio. The analysis, concerning the effect of the driving wheel parameters and road conditions on slip ratio estimation, shows that the peak estimation error can be reduced up to 75% when the LPF is adopted. The robustness and effectiveness of the LPF are therefore validated. This paper builds up the deformable tire model and the detailed I-PMSM models, and analyzes the effect of the driving wheel parameters and road conditions on slip ratio estimation. | LI Jianqiu SONG Ziyou WEI Yintao OUYANG Minggao | 2014 | Chinese Journal of Mechanical Engineering2014,27,6: | 4 |
| 5 | Research on modeling of heat source for electron beam welding fusion-solidification zone显示文摘In this paper, the common heat source model of point and linear heat source in the numerical simulation of electron beam welding (EBW) were summarized and introduced. The combined point-linear heat source model was brought forward and to simulate the welding temperature fields of EBW and predicting the weld shape. The model parameters were put forward and regulated in the combined model, which included the ratio of point heat source to linear heat source Qpr and the distribution of linear heat source Lr. Based on the combined model, the welding temperature fields of EBW were investigated. The results show that the predicted weld shapes are conformable to those of the actual, the temperature fields are reasonable and correct by simulating with combined point-linear heat source model and the typical weld shapes are gained. | Wang Yajun Fu Pengfei Guan Yongjun Lu Zhijun Wei Yintao | 2013 | Chinese Journal of Aeronautics2013,26,1: | 3 |
| 6 | Formation and evolution of the tertiary carbonate reefs in the Madura Strait Basin of Indonesia显示文摘Analysis of 2 D seismic data over 4 500 km in length from the Madura Strait Basin in the East Java Sea reveals seismic re?ection characteristics of reefs and associated sedimentary bodies, including asymmetrical or symmetrical dome re?ections, slope progradational re?ections, chaotic re?ections and discontinuous strong re?ections inside the reef, which onlap the ?ank of the reef. It is concluded that the developmental paleo-environment of most reefs is mainly conducive to shallow marine carbonate platform facies and platform margin facies, based on well core data, variations in seismic facies and strata thickness.The formation and evolution of all reefs are primarily in?uenced by the tectonic framework of the Madura Strait Basin. Platform margin reefs are principally controlled by two types of structures: one is a series of E-W trending Paleogene normal faults, and the other is an E-W trending Neogene inversion structures. In addition, wave actions, tidal currents and other ocean currents play an accelerated role in sorting, rounding and redeposition for the accumulation and evolution of reefs. Tertiary reefs in the MSB can be divided into four types: 1) an open platform coral reef of Late Oligocene to Early Miocene, 2) a platform margin coral reef controlled by normal faults in Late Oligocene to Early Miocene, 3) a platform margin Globigerina moundreef controlled by a 'hidden' inversion structure in Early Pliocene, and 4) a platform margin Globigerina mound-reef controlled by thrust faults in the early Pliocene. Patterns of the formation and evolution of reefs are also suggested. | RAN Weimin LUAN Xiwu LU Yintao LIU Hong YANG Jiajia ZHAO Yang HE Wenchang YAN Zhonghui | 2019 | Journal of Oceanology and Limnology2019,37,1: | 3 |
| 7 | Path Following Control for UAV Using Deep Reinforcement Learning Approach显示文摘Unmanned aerial vehicles(UAVs)have been extensively used in civil and industrial applications due to the rapid development of the guidance,navigation and control(GNC)technologies.Especially,using deep reinforcement learning methods for motion control acquires a major progress recently,since deep Q-learning algorithm has been successfully applied to the continuous action domain problem.This paper proposes an improved deep deterministic policy gradient(DDPG)algorithm for path following control problem of UAV.A speci-c reward function is designed for minimizing the cross-track error of the path following problem.In the training phase,a double experience replay bu®er(DERB)is used to increase the learning e±ciency and accelerate the convergence speed.First,the model of UAV path following problem has been established.After that,the framework of DDPG algorithm is constructed.Then the state space,action space and reward function of the UAV path following algorithm are designed.DERB is proposed to accelerate the training phase.Finally,simulation results are carried out to show the e®ectiveness of the proposed DERB–DDPG method. | Yintao Zhang Youmin Zhang Ziquan Yu | 2021 | Guidance, Navigation and Control2021,1,1: | 2 |

| 9 | Photoinduced charge injection in the metal/organic interface studied by transient photovoltage measurements with bias显示文摘Transient photovoltage of ITO/organic/Al cells is studied under different bias polarities and voltages.It is found that for an ITO/NPB/Al cell,light incidence on the Al side induces more bias-dependent transient photovoltage variation when the photovoltage is positive than when it is negative.However,for an ITO/C60 /Al cell,the variation characteristics of transient photovoltage is reversed.These results support the previously proposed mechanism that Al could inject charges into the organic layer upon photon excitation,indicating that the absorption of electrode can also contribute to photovoltaic effect. | WU Bo LI WenBin YU HaoMiao YOU YinTao CHEN XiaoQing HE Yun HOU XiaoYuan | 2013 | Science China(Physics,Mechanics & Astronomy)2013,56,10: | 2 |
| 10 | A New Growth Model of Fault Attributes in a Strike-Slip Fault System in the Tarim Basin显示文摘Fault attributes generally display a consistent power–law-scaling relationship.Based on new 3 D seismic data,however,we found some exceptional fault attribute relationships of lengths(L)–throw(T)(vertical component of displacement),overlap zone length(Lo)–width(Wo)from a strike-slip fault system of the Ordovician carbonates in the Tarim Basin.The L–T relationship shows two linear segments with breakup at^40 km in fault length.This presents an exceptional throw increase in the second stage,which is attributed to a localization of vertical displacement and deformation in overlapping zones other than the different fault scales in a mature fault zone.The Lo–Wo relationship in the overlapping zones shows multiply stepped-shape patterns,suggesting multiple fault differential growth and periodic increase in fault size.Therefore,we propose a new alternative growth model of fault attributes in strike-slip fault zones,in which the overlapping zones accumulated localized displacement and deformation in the intracratonic strike-slip fault zone. | ZHANG Yintao WU Guanghui WANG Junfang LI Guohui WAN Xiaoguo YANG Tianyi | 2020 | Acta Geologica Sinica(English Edition)2020,94,5: | 1 |
| 11 | Dengue Fever Outbreaks Caused by Varied Serotype Dengue Virus--Guangdong Province,China,2019显示文摘What is already known about this topic?Dengue fever(DF)outbreaks affect hundreds of millions of people worldwide and have increased significantly in Guangdong Province in 2019.What is added by this report?This paper described briefly DF outbreaks were attributed to several types of dengue virus(DENV)including DENV-1,DENV-2,and DENV-3 in 2019 in Guangdong,tracked the sources of viruses through phylogenetic analysis and epidemiological investigation,and primarily revealed the epidemiological links among the outbreaks.What are the implications for public health practice?The introduction of DENV from DF endemic areas increased pressure on the prevention and control of DF in Guangdong.Early detection of suspected cases and typing and genotyping of circulating viruses should be prioritized and enhanced to promptly assess the likelihood of local transmission,of introduction,and of subsequent sustained local transmission of the virus to implement optimal prevention and control strategies and measures. | De Wu Xin Zhang Aiping Deng Huan Zhang Yintao Zhang Qiqi Tan Zhiqiang Peng Jiandong Li Tie Song | 2020 | China CDC weekly2020,2,38: | 1 |

| 18 | Species-level monitoring of rare and invasive fishes using eDNA metabarcoding in the middle and upper Yarlung Zangbo River, Tibet显示文摘Fish diversity of the Yarlung Zangbo River is very sensitive and vulnerable to biological invasion,anthropogenic activities and climate change,especially in the upper and middle reaches where several endemic fishes have become endangered and nearly ten invasive fishes have been established.Here,we used environmental DNA(eDNA)metabarcoding to monitor rare and invasive fishes,and to assess diversity in 25 sites from two wetlands(Lalu and Chabalang)and the main channel(YT),within the upper and middle reaches.To obtain a species-level resolution,we evaluated species discrimination potentials of three mitochondrial markers and found Cytb had the highest average genetic distance at each taxonomic level followed by COI and 12S.The 12S was unqualified for species assignment,as two species shared identical haplotypes.The newly designed Cytb primers used for metabarcoding showed an average mismatch of 0.28 and amplified well across species.In total,8942 operational taxonomic units(OTUs)were obtained based on a 100%identity threshold,among which 98.1%were assigned to 24 fishes based on our custom-made database and the remaining were assigned to six fishes based on the NCBI nt database.Almost all captured fishes were detected by the eDNA method except for two species.However,12 fishes detected by the eDNA method were not listed in catch data for several sites,including one endangered species(Oxygymnocypris stewartii),four previously recorded non-native species and two unrecorded non-native species(Monopterus albus and Siniperca chuatsi).The alpha diversities estimated by eDNA and capture-based methods were correlated for sites at Lalu.Both methods revealed significant differences in community composition between YT and the wetlands.Our results provide both basic information for conservation and management of rare and invasive fishes in the Yarlung Zangbo River and a framework of fish eDNA metabarcoding with a species-level resolution. | Xiu Feng Bing Li Yifeng Chen Ren Zhu Yintao Jia Xiaoyun Sui | 2023 | Water Biology and Security2023,2,1: | 1 |
