| 1 | Nonlinear Adaptive Robust Force Control of Hydraulic Load Simulator显示文摘This paper deals with the high performance force control of hydraulic load simulator. Many previous works for hydraulic force control are based on their linearization equations, but hydraulic inherent nonlinear properties and uncertainties make the conventional feedback proportional-integral-derivative control not yield to high-performance requirements. In this paper, a nonlinear system model is derived and linear parameterization is made for adaptive control. Then a discontinuous projection-based nonlinear adaptive robust force controller is developed for hydraulic load simulator. The proposed controller constructs an asymptotically stable adaptive controller and adaptation laws, which can compensate for the system nonlinearities and uncertain parameters. Meanwhile a well-designed robust controller is also developed to cope with the hydraulic system uncertain nonlinearities. The controller achieves a guaranteed transient performance and final tracking accuracy in the presence of both parametric uncertainties and uncertain nonlinearities; in the absence of uncertain nonlinearities, the scheme also achieves asymptotic tracking performance. Simulation and experiment comparative results are obtained to verify the high-performance nature of the proposed control strategy and the tracking accuracy is greatly improved. | YAO Jianyong JIAO Zongxia YAO Bin SHANG Yaoxing DONG Wenbin | 2012 | Chinese Journal of Aeronautics2012，25，5： | 17 |
| 2 | L-3-n-butylphthalide protects against vascular dementia via activation of the Akt kinase pathway显示文摘As a neuroprotective drug for the treatment of ischemic stroke, 3-n-butylphthalide, a celery seed extract, has been approved by the State Food and Drug Administration of China as a clinical therapeutic drug for ischemic stroke patients. L-3-n-butylphthalide possesses significant efficacy in the treatment of acute ischemic stroke. The activated Akt kinase pathway can prevent the death of nerve cells and exhibit neuroprotective effects in the brain after stroke. This study provides the hypothesis that l-3-n-butylphthalide has a certain therapeutic effect on vascular dementia, and its mechanism depends on the activation of the Akt kinase pathway. A vascular dementia mouse model was established by cerebral repetitive ischemia/reperfusion, and intragastrically administered l-3-n-butylphthalide daily for 28 consecutive days after ischemia/reperfusion, or 7 consecutive days before ischemia/reperfusion. The Morris water maze test showed significant impairment of spatial learning and memory at 4 weeks after operation, but intragastric administration of l-3-n-butylphthalide, especially pretreatment with l-3-n-butylphthalide, significantly reversed these changes. Thionine staining and western blot analylsis showed that preventive and therapeutic application of l-3-n-butylphthalide can reduce loss of pyramidal neurons in the hippocampal CA1 region and alleviate nerve damage in mice with vascular demen-tia. In addition, phosphorylated Akt expression in hippocampal tissue increased significantly after l-3-n-butylphthalide treatment. Experimental findings demonstrate that l-3-n-butylphthalide has preventive and therapeutic effects on vascular dementia, and its mechanism may be mediated by upregulation of phosphorylated Akt in the hippocampus. | Yaping Huai Yanhong Dong Jing Xu Nan Meng Chunfeng Song Wenbin Li Peiyuan Lv | 2013 | Neural Regeneration Research2013，8，19： | 17 |
| 3 | Cropland redistribution to marginal lands undermines environmental sustainability显示文摘Cropland redistribution to marginal land has been reported worldwide;however,the resulting impacts on environmental sustainability have not been investigated sufficiently.Here we investigated the environmental impacts of cropland redistribution in China.As a result of urbanization-induced loss of high-quality croplands in south China(~8.5 t ha^(-1)),croplands expanded to marginal lands in northeast(~4.5 t ha^(-1)) and northwest China(~2.9 t ha^(-1)) during 1990-2015 to pursue food security.However,the reclamation in these low-yield and ecologically vulnerable zones considerably undermined local environmental sustainability,for example increasing wind erosion(+3.47%),irrigation water consumption(+34.42%),fertilizer use(+20.02%) and decreasing natural habitats(-3.11%).Forecasts show that further reclamation in marginal lands per current policies would exacerbate environmental costs by 2050.The future cropland security risk will be remarkably intensified because of the conflict between food production and environmental sustainability.Our research suggests that globally emerging reclamation of marginal lands should be restricted and crop yield boost should be encouraged for both food security and environmental benefits. | Wenhui Kuang Jiyuan Liu Hanqin Tian Hao Shi Jinwei Dong Changqing Song Xiaoyong Li Guoming Du Yali Hou Dengsheng Lu Wenfeng Chi Tao Pan Shuwen Zhang Rafiq Hamdi Zherui Yin Huimin Yan Changzhen Yan Shixin Wu Rendong Li Jiuchun Yang Yinyin Dou Wenbin Wu Liqiao Liang Bao Xiang Shiqi Yang | 2022 | National Science Review2022，9，1： | 13 |
| 4 | The Assessment of Global Surface Temperature Change from 1850s:The C-LSAT2.0 Ensemble and the CMST-Interim Datasets显示文摘Based on C-LSAT2.0,using high-and low-frequency components reconstruction methods,combined with observation constraint masking,a reconstructed C-LSAT2.0 with 756 ensemble members from the 1850s to 2018 has been developed.These ensemble versions have been merged with the ERSSTv5 ensemble dataset,and an upgraded version of the CMSTInterim dataset with 5°×5°resolution has been developed.The CMST-Interim dataset has significantly improved the coverage rate of global surface temperature data.After reconstruction,the data coverage before 1950 increased from 78%−81%of the original CMST to 81%−89%.The total coverage after 1955 reached about 93%,including more than 98%in the Northern Hemisphere and 81%−89%in the Southern Hemisphere.Through the reconstruction ensemble experiments with different parameters,a good basis is provided for more systematic uncertainty assessment of C-LSAT2.0 and CMSTInterim.In comparison with the original CMST,the global mean surface temperatures are estimated to be cooler in the second half of 19th century and warmer during the 21st century,which shows that the global warming trend is further amplified.The global warming trends are updated from 0.085±0.004℃(10 yr)^(–1)and 0.128±0.006℃(10 yr)^(–1)to 0.089±0.004℃(10 yr)^(–1)and 0.137±0.007℃(10 yr)^(–1),respectively,since the start and the second half of 20th century. | Wenbin SUN Qingxiang LI Boyin HUANG Jiayi CHENG Zhaoyang SONG Haiyan LI Wenjie DONG Panmao ZHAI Phil JONES | 2021 | Advances in Atmospheric Sciences2021，38，5： | 8 |
| 5 | Intensive phototherapy vs.exchange transfusion for the treatment of neonatal hyperbilirubinemia:a multicenter retrospective cohort study显示文摘Background:Intensive phototherapy(IPT)and exchange transfusion(ET)are the main treatments for extreme hyperbilirubinemia.However,there is no reliable evidence on determining the thresholds for these treatments.This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia.Methods:This retrospective cohort study was conducted in seven centers from January 2015 to January 2018.Patients with extreme hyperbilirubinemia that met the criteria of ET were included.Patients were divided into three subgroups(low-,medium-,and high-risk)according to gestational week and risk factors.Propensity score matching(PSM)was performed to balance the data before treatment.Study outcomes included the development of bilirubin encephalopathy,duration of hospitalization,expenses,and complications.Mortality,auditory complications,seizures,enamel dysplasia,ocular motility disorders,athetosis,motor,and language development were evaluated during follow-up at age of 3 years.Results:A total of 1164 patients were included in this study.After PSM,296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-,medium-,and high-risk subgroups with 188,364,and 40 matched patients,respectively.No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity,complications,and sequelae.Hospitalization duration and expenses were lower in the low-and medium-risk subgroups in the IPT only group.Conclusions:In this study,our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia.The indication of ET for patients with hyperbilirubinemia could be stricter.However,it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors.If IPT can be guaranteed and proved to be therapeutic,ET should be avoided as much as possible. | Meng Zhang Yang He Jun Tang Wenbin Dong Yong Zhang Benjin Zhang Hong Wan Quanmin Deng Lirong Guan Bin Xia Zhong Chen Min Ge Jing Zhao Wenxing Li Jingjun Pei Yi Qu Dezhi Mu | 2022 | Chinese Medical Journal2022，，5： | 7 |
| 6 | Electron Probe Microanalysis of Monazite and Its Applications to U-Th-Pb Dating of Geological Samples显示文摘Electron probe microanalysis(EPMA) dating of monazite has been developed over decades. However, limited by the detectability and analytical sensitivity of dating-related elements(Th, Pb, U and Y), the EPMA dating has been restricted to geological research. In this study, various probe currents, beam diameters and counting times have been utilized on a JEOL JXA-8230 electron microprobe to determine the optimal experimental conditions for measuring Th, Pb, U and Y in monazite. The optimal conditions are:(1) accelerating voltage is 15 k V;(2) probe current is 100 n A;(3) beam diameter is 1 μm;(4) the peak and background counting time of U and Pb are 200 and 100 s;and(5) the peak and background counting time of Th and Y are 100 and 50 s. We apply this method to monazite from garnet-bearing biotite gneiss in the Zanhuang area of the Central Orogenic Belt of the North China Craton. The Pb O-Th O2* isochron age calculated by EPMA data is 1 812±17 Ma(MSWD=2.06), which is similar to the weighted mean 207 Pb/206 Pb age(1 805±12 Ma, MSWD=1.07) obtained by LA-ICP-MS. This study suggests that EPMA dating of monazite as a powerful dating technique can be widely used in geochronological study. | Wenbin Ning Junpeng Wang Deng Xiao Fenfang Li Bo Huang Dong Fu | 2019 | Journal of Earth Science2019，30，5： | 5 |
| 7 | Characterization of event-related potentials in obsessive compulsive disorder patients: Comparison with depression and generalized anxiety disorder patients显示文摘BACKGROUND: Study results of event-related potential in obsessive compulsive disorder (OCD) remain controversial, potentially as a result of different instruments utilized and their differing technical characteristics. OBJECTIVE: To investigate the differences in several common event-related potentials, i.e. contingent negative variations, P300, and mismatch negativity (MMN), in OCD patients, depression patients, generalized anxiety disorder (GAD) patients, and healthy controls. DESIGN, TIME AND SETTING: A case-control study was performed in the Department of Electrophysiology, Shanghai Mental Health Center from May 2002 to December 2005. PARTICIPANTS: A total of 38 OCD patients, 20 depression patients, and 18 GAD patients, who were diagnosed according to the criteria of Chinese Classification of Mental Disorders (Version 3), formulated by the Chinese Psychiatry Association, were selected from the Outpatient Department o Shanghai Mental Health Center. Patients with two or more the above diseases were excluded. In addition, 28 healthy people, gender and age matched, were selected as controls. METHODS: Contingent negative variations, P300, and MMN were recorded by a Nicolet Spirit Instrument. All electrodes were attached at Cz according to the International 10-20 system, with the mastoid leads as reference and Fpz as ground. MAIN OUTCOME MEASURES: Amplitude and latency of contingent negative variations, P300, and MMN. RESULTS: The contingent negative variations, P300, and MMN were different (P < 0.01). OCD patients showed an increased M1 amplitude compared with controls, depression, and GAD patients (P < 0.01). Target P300 amplitudes were significantly lower in OCD, depression, and GAD patients compared with controls (P < 0.01). Moreover, N2 latency and latency of MMN were prolonged in OCD and depression groups compared with controls (P < 0.05). CONCLUSION: Event-related potentials were different in depression, GAD, and OCD patients and healthy controls. In particular, OCD patients exhibited unique characteristics. | Yingzhi Lu Wenbin Zong Hanzhen Dong Faxin Wang Jinyu PU Xingshi Chen Yunxiang Tang | 2010 | Neural Regeneration Research2010，5，12： | 5 |
| 8 | Size,morphology,and composition of lunar samples returned by Chang'E-5 mission显示文摘This study focuses on the physical and chemical properties of surficial lunar regolith(LR)samples returned from the Moon by the Chang’E-5(CE-5)mission.Insights regarding the effect of a new sampling geological site on the surficial lunar sample CE5 C0400 were illustrated using nondestructive techniques such as laser diffractometry coupled with image analysis,X-ray computed tomography,and field emission scanning electron microscopy equipped with energy dispersive spectroscopy,and Xray diffraction combined with Rietveld refinement.From the characterization analyses,the CE-5 sampling site in the northeastern Oceanus Procellarum on the Moon yields a unique collection of relatively regular-shaped and fine basalt-dominated particles.The median grain size D_(50) is(55.24±0.96)μm,falling within the relatively low end of the range of the Apollo lunar returned samples.The coefficient of uniformity C_(u)of 15.1 and the coefficient of curvature C_(c)of 1.7 could classify CE5 C0400 to be well-graded.The minerals in CE5 C0400 comprise approximately 44.5%pyroxene,30.4%plagioclase,3.6%olivine,and6.0%ilmenite.There is a relatively low content of approximately 15.5%glass phase in the CE-5 lunar sample.From the results,we deduce that the CE-5 LR structure could have mainly resulted from micrometeoroid impacts to achieve such a high level of maturity. | Hui Zhang Xian Zhang Guang Zhang Keqi Dong Xiangjin Deng Xiaosong Gao Yaodong Yang Yuan Xiao Xiao Bai Kaixin Liang Yiwei Liu Wenbin Ma Shaofan Zhao Ce Zhang Xiaojing Zhang Jian Song Wei Yao Hong Chen Weihua Wang Zhigang Zou Mengfei Yang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，2： | 4 |
| 9 | Experimental and Numerical Investigation of Local Scour Around Submarine Piggyback Pipeline Under Steady Current显示文摘As a new type of submarine pipeline, the piggyback pipeline has been gradually adopted in engineering practice to enhance the performance and safety of submarine pipelines. However, limited simulation work and few experimental studies have been published on the scour around the piggyback pipeline under steady current. This study numerically and experimentally investigates the local scour of the piggyback pipe under steady current. The influence of prominent factors such as pipe diameter, inflow Reynolds number, and gap between the main and small pipes, on the maximum scour depth have been examined and discussed in detail. Furthermore, one formula to predict the maximum scour depth under the piggyback pipeline has been derived based on the theoretical analysis of scour equilibrium. The feasibility of the proposed formula has been effectively calibrated by both experimental data and numerical results. The findings drawn from this study are instructive in the future design and application of the piggyback pipeline. | ZHAO Enjin SHI Bing QU Ke DONG Wenbin ZHANG Jing | 2018 | Journal of Ocean University of China2018，17，2： | 3 |
| 10 | Decomposition of the Unsteady Wave Patterns for Bessho form Translating-Pulsating Source Green Function显示文摘In order to interpret the physical feature of Bessho form translating-pulsating source Green function, the phase function is extracted from the integral representation and stationary-phase analysis is carried out in this paper. The complex characteristics of the integral variable and segmentation of the integral intervals are discussed in m complex plane. In θ space, the interval [-π/2+φ,-π/2+φ-iε] is dominant in the near-field flow, and there is a one-to-one correspondence between the real intervals in m space and the unsteady wave patterns in far field. If 4τ>1(τ is the Brard number), there are three kinds of propagation wave patterns such as ring-fan wave pattern, fan wave pattern and inner V wave pattern, and if 0<4τ<1, a ring wave pattern, an outer V and inner V wave pattern are presented in far field. The ring-fan or ring wave pattern corresponds to the interval [-π+α,-π/2+φ] for integral terms about k2, and the fan or outer V wave pattern and inner V wave pattern correspond to [-π+α,-π/2) and(-π/2,-π/2+φ] respectively for terms about k1. Numerical result shows that it is beneficial to decompose the unsteady wave patterns under the condition of τ≠0 by converting the integral variable θ to m. In addition, the constant-phase curve equations are derived when the source is performing only pulsating or translating. | XIAO Wenbin DONG Wencai | 2014 | Journal of Ocean University of China2014，13，5： | 3 |
| 11 | The role of personality,social economic and prevention strategy effects on health-related quality of life among people living with HIV/AIDS显示文摘Background::HIV/AIDS has transformed into a chronic controllable but not yet curable infectious disease as other chronic diseases to some extent.The additional of so called fourth 90%that included the improved health-related quality of life(HRQoL)for people living with HIV(PLWHIV)required solutions beyond antiretroviral therapy and viral load suppression.This study will explore the role of personality,social economic and prevention strategy effection on HRQoL among people living with HIV/AIDS.Methods::A cross-sectional study was conducted among PLWHIV aged more than 16 years old in the 10 municipalities in Yunnan Province,China from October 2019 to May 2020,enrolling total 1997 participants.Individual-level HRQoL data were measured by 12-item Short Form Health Survey(SF-12)and EuroQol Five Dimensions Questionnaire(EQ-5D-5L).We assembled municipal-level data about social economic from Yunnan Statistical Yearbook in 2020 and strategy practice information from the self-evaluation system.We used the principal component analysis to build the social economic and strategy effect on each area respectively and one-way ANOVA was used to perform univariate analysis to identify the predictors with significant differences.Finally we used multi-level model(MLM)to explore the personality,social economic and strategy effects in health-related quality of life among PLWHIV.Results::The global score for quality of life measured using EQ-5D-5L had an estimated mean score(standard deviation,SD)of 0.901±0.146.The HRQoL score measured using PCS-12 had an estimated mean score(SD)of 46.62±8.55.The mean MCS-12 score(SD)was estimated to be 47.80±9.71.The area-level predictors explained a proportion of 13.6-17.2%for the between-area variation of the HRQoL scores,regardless of the total HRQoL,physical component and mental component.The impacts of stigma(P<0.01),social support(P<0.001),anxiety(P<0.001),depression(P<0.05)and social economic status(P<0.05)on HRQoL at the individual-level were significantly different.The plots visualized the impact of individual-level factors on a respondent’s HRQoL was modified by the area-level characteristics.Conclusions::The study identified the possible strategy determinant of individual HRQoL of PLWHIV and also the area effect on HRQoL.Stigma,social support,anxiety,depression and social economic status were the individual-level determinants on HRQoL.These could be a valuable resource for evaluating the overall health of the areas and help improve local decision making. | Xiaowen Wang Hongbing Luo Enlong Yao RenhaiTang Wenbin Dong Fuyong Liu Jun Liang Huilan Li Minyang Xiao Zuyang Zhang Jin Niu Lijun Song Liru Fu Xuehua Li Shicong Qian Qing Guo Zhizhong Song | 2021 | Infectious Diseases of Poverty2021，10，4： | 3 |
| 12 | Profiles of and variations in aluminum species in PAC-MC used for the removal of blooming microalgae显示文摘Polyaluminum chloride modified clay(PAC-MC)is a safe and efficient red tide control agent that has been studied and applied worldwide.Although it is well known that the distribution of hydrolytic aluminum species in PAC affects its flocculation,little is known about the influence of particulars aluminum species on the microalgae removal efficiency of PAC-MC;this lack of knowledge creates a bottleneck in the development of more efficient MCs based on aluminum salts.The ferron method was used in this study to quantitatively analyze the distributions of and variations in different hydrolytic aluminum species during the process of microalgae removal by PAC-MC.The results showed that Ala,which made up 5%–20%of the total aluminum,and Alp,which made up 15%–55%of the total aluminum,significantly affected microalgae removal,with Pearson’s correlation coefficients of 0.83 and 0.89,respectively.Most of the aluminum in the PAC-MC sank rapidly into the sediments,but the rate and velocity of settlement were affected by the dose of modified clay.The optimal dose of PAC-MC for precipitating microalgae was determined based on its aluminum profile.These results provide guidance for the precise application of PAC-MC in the control of harmful algal blooms. | Xueyi Dong Xihua Cao Wenbin Jiang Xiuxian Song Zhiming Yu Shitao Yu | 2021 | Journal of Environmental Sciences2021，33，8： | 2 |

| 14 | Atmospheric Excitation of Polar Motion显示文摘The polar motion excited by the fluctuation of global atmospheric angular momentum (AAM) is investigated. Based on the global AAM data, numerical results demonstrate that the fluctuation of AAM can excite the seasonal wobbles (e.g., the 18-month wobble) and the Chandler wobble, which agree well with previous studies. In addition, by filtering the dominant low frequency components, some distinct polar wobbles corresponding to some great diurnal and semi-diurnal atmospheric tides are found. | CHEN Wei SHEN Wenbin DONG Xiaowei | 2010 | Geo-Spatial Information Science2010，13，2： | 2 |
| 15 | Machine learning for detecting mesial temporal lobe epilepsy by structural and functional neuroimaging显示文摘Mesial temporal lobe epilepsy(mTLE),the most common type of focal epilepsy,is associated with functional and structural brain alterations.Machine learning(ML)techniques have been successfully used in discriminating mTLE from healthy controls.However,either functional or structural neuroimaging data are mostly used separately as input,and the opportunity to combine both has not been exploited yet.We conducted a multimodal ML study based on functional and structural neuroimaging measures.We enrolled 37 patients with left mTLE,37 patients with right mTLE,and 74 healthy controls and trained a support vector ML model to distinguish them by using each measure and the combinations of the measures.For each single measure,we obtained a mean accuracy of 74%and 69%for discriminating left mTLE and right mTLE from controls,respectively,and 64%when all patients were combined.We achieved an accuracy of 78%by integrating functional data and 79%by integrating structural data for left mTLE,and the highest accuracy of 84%was obtained when all functional and structural measures were combined.These findings suggest that combining multimodal measures within a single model is a promising direction for improving the classification of individual patients with mTLE. | Baiwan Zhou Dongmei An Fenglai Xiao Running Niu Wenbin Li Wei Li Xin Tong Graham J Kemp Dong Zhou Qiyong Gong Du Lei | 2020 | Frontiers of Medicine2020，14，5： | 2 |
| 16 | The modelling of quantum control systems显示文摘High-performance control of quantum dynamics is key to the development of quantum technologies.From quantum-state engineering to quantum metrology,theory and practice of quantum control enable robust and cheaper technologies for future industrial applications.Starting from fundamental matter–field interactions, we overview various approaches to modelling quantum control systems, in which control can be implemented by either changing field or material properties. These models are built in time or frequency domain and can be interconnected to form quantum feedback networks. This review can be taken as a useful reference for engineers to understand the quantum physics behind, or for physicists to resolve control problems from a control engineering point of view. | Wenbin Dong Rebing Wu Xiaohu Yuan Chunwen Li Tzyh-Jong Tarn | 2015 | Science Bulletin2015，60，17： | 2 |
