1Research progress on silicon/carbon composite anode materials for lithium-ion battery显示文摘Silicon(Si) has been considered as one of the most promising anode material for the next generation lithium-ion batteries(LIBs) with high energy densities, due to its high theoretical capacity, abundant availability and environmental friendliness. However, silicon materials with low intrinsic electric and ionic conductivity suffer from huge volume variation during lithiation/delithiation processes leading to the pulverization of Si and subsequently resulting in severe capacity fading of the electrodes. Coupling of Si with carbon(C) realizes a favorable combination of the two materials properties, such as high lithiation capacity of Si and excellent mechanical and conductive properties of C, making silicon/carbon composite(Si/C) ideal candidates for LIBs anodes. In this review, recent progresses of Si/C materials utilized in LIBs are summarized in terms of structural design principles, material synthesis methods, morphological characteristics and electrochemical performances by highlighting the material structures. The mechanisms behind the performance enhancement are also discussed. Moreover, other factors that affect the performance of Si/C anodes, such as prelithiation, electrolyte additives, and binders, are also discussed. We aim to present a full scope of the Si/C-based anodes, and help understand and design future structures of Si/C anodes in LIBs.Xiaohui Shen Zhanyuan Tian Ruijuan Fan Le Shao Dapeng Zhang Guolin Cao Liang Kou Yangzhi Bai 2018Journal of Energy Chemistry2018,27,4:29

3Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders: executive summary and 2019 update of clinical management of cerebral venous sinus thrombosis显示文摘Aim Cerebral venous sinus thrombosis(CVST)is a less common cerebrovascular disease that predominantly affects young patients.The incidence of CVST is 2-5/10000000/year,accounting for 0.5%-1%of all stroke.To reduce mortality and morbidity associated with CVST,Chinese Stroke Association commissioned the authors to write the current guideline on the management of CVST.Methods PubMed(MEDLINE),CNKI and Wanfang database were searched for studies related to CVST from 1 January 1990 to 31 July 2019.Data were synthesised by evidence tables.Each recommendation was fully discussed by the writing group members and reviewed by Chinese Stroke Association Stroke Fellow Committees.Levels of evidence grading algorithm of Chinese Stroke Association was used to grade each recommendation.results This guideline mainly focuses on the diagnostic evaluation,therapeutic strategies and secondary prevention of CVST.CT/CTV and MRI/MRV are recommended in the initial imaging evaluation of patients with suspected CVST.Anticoagulation therapy with low-molecular weight heparin should be initiated in patients with CVST immediately.After the acute stage,warfarin is recommended for 3-6 months to prevent the recurrence of CVST and other venous thromboembolic events.Conclusions The guideline summarises the current evidence regarding the management of CVST,and provides references for diagnosis,treatment and secondary prevention of CVST in China.Yuhua Fan Jian Yu Hongbing Chen Jian Zhang Jiangang Duan Dapeng Mo Wenhao Zhu Bo Wang Fubing Ouyang Yicong Chen Linfang Lan Jinsheng Zeng Chinese Stroke Association Stroke Council CVST Guideline Writing Committee 2020Stroke & Vascular Neurology2020,5,2:14
4Sulfur isotopic composition of the Bainiuchang super-large Ag polymetallic deposit,Yunnan Province,China: Implications for the source of sulfur in ore-forming fluids显示文摘The Bainiuchang deposit in Yunnan Province, China, is located geographically between the Gejiu ore field and the Dulong ore field. In addition to >7000 t Ag reserves, the deposit possesses large-scale Pb, Zn, Sn reserves and a mass of dispersed elements (i.e., In, Cd, Ge, Ga, etc.). Based on systematic studies of sulfur isotopic composition, the authors conclude: The Bainiuchang deposit experienced two epochs of metallogenesis, i.e., the Middle-Cambrian sea-floor exhalative sedimentary metallogenic epoch and the Yanshanian magmatic hydrothermal superimposition metallogenic epoch. In the two metallogenic epochs, the δ34S values of sulfides were all near 0, showing a tendency of being enriched slightly in heavy sulfur. The δ34S values of sulfides in the early metallogenic epoch are within the range of 2‰–5‰ with a peak value range of 2‰–3‰ and an average of 3.0‰, and those of sulfides in the late metallogenic epoch are within the range of 2‰–6‰ with a peak value of 3‰–4‰ and an average of 3.9‰. For the single metallogenic epoch, sulfur in the ore-forming fluids in the early epoch already reached isotopic equilibrium and was derived mainly from underneath the magma chamber or basement metamorphic igneous rocks. Sulfur in the sulfides in the late epoch was derived mainly from magmatic hydrothermal fluids formed in the process of remelting of the basement metamorphic igneous rocks.XIE Hongjing ZHU Chaohui ZHANG Qian WANG Dapeng FAN Liangwu 2009Chinese Journal Of Geochemistry2009,28,3:7
5Development of a CH4 dehydroaromatization–catalyst regeneration fluidized bed system显示文摘A pilot-scale methane dehydroaromatization–H_2regeneration fluidized bed system(MDARS)was developed.In the MDARS,the catalyst circulation between a fluidized bed reactor and a fluidized bed regenerator with the help of a catalyst feeder allowed methane dehydroaromatization(MDA)and H_2regeneration to be carried out simultaneously,which is good for maintaining a stable MDA catalytic activity.A fixed bed reactor(FB)and a single fluidized bed reactor(SFB)were also used for a comparative study.The experimental results showed that the catalytic activity in the MDARS was more stable than that in the FB and SFB reactors.The effects of some parameters of MDARS on the CH_4conversion and product selectivity were investigated.To verify the feasibility and reliability of the MDARS,an eight-hour long-term test was carried out,which demonstrated that the operation of the MDARS was stable and that the catalytic activity remained stable throughout the entire experimental period.Peng Yan Zhanguo Zhang Dapeng Li Xu Cheng Xinzhuang Zhang Fan Yang Chuanfeng Huang Xiaoxun Ma 2018Chinese Journal of Chemical Engineering2018,26,9:5
6Application in prestiction friction compensation for angular velocity loop of inertially stabilized platforms显示文摘To overcome the influence of the nonlinear friction on the gimbaled servo-system of an inertial stabilized platforms(ISPs) with DC motor direct-drive, the methods of modeling and compensation of the nonlinear friction are proposed. Firstly, the inapplicability of LuGre model when trying to interpret the backward angular displacement in the prestiction regime is observed experimentally and the reason is deduced theoretically. Then, based on the dynamic model of direct-drive ISPs, a modified LuGre model is proposed to describe the characteristic of the friction in the prestiction regime. Furthermore, the state switch condition of the three friction regimes including presliding, gross sliding and prestiction is presented. Finally, a composite compensation controller including a nonlinear friction observer and a feedforward compensator based on the novel LuGre model is designed to restrain the nonlinear friction and to improve the control precision. Experimental results indicate that compared with those of the conventional proportion–integration–differentiation(PID) control method and the PID plus LuGre model-based friction compensation method, the dwell-time has decreased from 0.2 s to almost 0 s, the position error decreased to 86.7%and the peak-to-peak value of position error decreased to 80% after the novel compensation controller is added. It concludes that the composite compensation controller can greatly improve the control precision of the dynamic sealed ISPs.Zhang Zhiyong Li Zhiqiang Zhou Qingkun Zhang Lianchao Fan Dapeng 2014Chinese Journal of Aeronautics2014,27,3:5
7Nuclear Aurora kinase A switches m^(6)A reader YTHDC1 to enhance an oncogenic RNA splicing of tumor suppressor RBM4显示文摘Aberrant RNA splicing produces alternative isoforms of genes to facilitate tumor progression,yet how this process is regulated by oncogenic signal remains largely unknown.Here,we unveil that non-canonical activation of nuclear AURKA promotes an oncogenic RNA splicing of tumor suppressor RBM4 directed by m^(6)A reader YTHDC1 in lung cancer.Nuclear translocation of AURKA is a prerequisite for RNA aberrant splicing,specifically triggering RBM4 splicing from the full isoform(RBM4-FL)to the short isoform(RBM4-S)in a kinase-independent manner.SiSi Li YangFan Qi JiaChuan Yu YuChao Hao Bin He MengJuan Zhang ZhenWei Dai TongHui Jiang SuYi Li Fang Huang Ning Chen Jing Wang MengYing Yang DaPeng Liang Fan An JinYao Zhao WenJun Fan YuJia Pan ZiQian Deng YuanYuan Luo Tao Guo Fei Peng ZhiJie Hou ChunLi Wang FeiMeng Zheng LingZhi Xu Jie Xu QingPing Wen BiLian Jin Yang Wang Quentin Liu 2022Signal Transduction and Targeted Therapy2022,7,5:4

11Staged angioplasty versus regular carotid artery stenting in patients with carotid artery stenosis at high risk of hyperperfusion:a randomised clinical trial显示文摘Background and purpose Hyperperfusion(HP)is a devastating complication associated with carotid artery stenting(CAS)or endarterectomy.The efficacy and safety of staged angioplasty(SAP)in patients with CAS at high risk of HP remains unclear.We sought to determine whether SAP is superior to regular CAS in patients with high risk of HP.Methods A randomised,multicentre open-label clinical trial with blinded outcome assessment(STEP)was conducted.Patients with severe carotid stenosis at high risk of HP were randomly assigned(1:1)to the SAP or regular CAS group.The primary endpoint was hyperperfusion syndrome(HPS)and intracerebral haemorrhage(ICH)within 30 days after the procedure.Results From November 2014 to January 2017,a total of 64 patients were enrolled in 11 centres.33 patients were allocated to the SAP group and 31 to the regular CAS group.At 30 days,the rate of primary endpoint was 0.0%(0/33)in the SAP group and 9.7%(3/31)in the regular CAS group(absolute risk reduction(ARR),9.7%;95%CI−20.1% to 0.7%;p=0.11).As one of the secondary endpoints,the incidence of HP phenomenon(HPP)was lower in the SAP group than the regular CAS group(0.0%vs 22.6%,ARR,−22.6%;95% CI−36.8%to−10.2%;p=0.04).Conclusion The rate of HPS and ICH was not significantly lower in SAP group;the extended secondary endpoint of HPP,however,significantly reduced,which suggested that SAP may be a safe and effective carotid revascularisation procedure to prevent HP.Dapeng Mo Baixue Jia Huaizhang Shi Yaxuan Sun Qingan Liu Chengzhe Fan Jianping Deng Jinglin Yuan Wei Wu Changchun Jiang Guilian Zhang Hanjun Du Ning Ma Feng Gao Xuan Sun Ligang Song Lian Liu Guangge Peng Yongjun Wang Yilong Wang Zhongrong Miao the STEP Study Group 2021Stroke & Vascular Neurology2021,6,1:3

13Double-loop robust tracking control for micro machine tools显示文摘This paper addresses double-loop robust tracking controller design of the miniaturized linear motor drive precision stage with mass and damping ratio uncertainties.As an inner-loop,a disturbance observer(DOB) is employed to suppress exogenous low frequency disturbances such as friction and cutting force.To further eliminate the residual disturbance and to guarantee the robust tracking to the reference input,a-synthesis outer-loop controller is designed.For eliminating the steady state error,a technique is proposed to design the-synthesis outer-loop controller with an integrator.A guideline to select the bandwidth of the Q-filter in the DOB is provided.Simulations using a model of a prototype micro-milling machine indicate that the proposed outer-loop synthesis scheme is superior to the H suboptimal control in disturbance rejection performance and steady state tracking performance.Furthermore,it is shown experimentally that the proposed double-loop robust tracking controller improves the tracking performance of the stage by 29.6% over PID control with a DOB inner-loop.FAN ShiXun NAGAMUNE Ryozo FAN DaPeng 2011Science China(Technological Sciences)2011,54,11:2
14Development of a CLDN18.2-targeting immuno-PET probe for non-invasive imaging in gastrointestinal tumors显示文摘Claudin18.2(CLDN18.2)is a tight junction protein that is overexpressed in a variety of solid tumors such as gastrointestinal cancer and oesophageal cancer.It has been identified as a promising target and a potential biomarker to diagnose tumor,evaluate efficacy,and determine patient prognosis.TST001 is a recombinant humanized CLDN18.2 antibody that selectively binds to the extracellular loop of human Claudin18.2.In this study,we constructed a solid target radionuclide zirconium-^(89)(^(89)Zr)labled-TST001 to detect the expression of in the human stomach cancer BGC823CLDN18.2 cell lines.The[^(89)Zr]Zr-desferrioxamine(DFO)-TST001 showed high radiochemical purity(RCP,>99%)and specific activity(24.15±1.34 GBq/mmol),and was stable in 5%human serum albumin,and phosphate buffer saline(>85%RCP at 96 h).The EC_(50) values of TST001 and DFO-TST001 were as high as 0.413±0.055 and 0.361±0.058 nM(P>0.05),respectively.The radiotracer had a significantly higher average standard uptake values in CLDN18.2-positive tumors than in CLDN18.2-negative tumors(1.11±0.02 vs.0.49±0.03,P=0.0016)2 days post injection(p.i.).BGC823CLDN18.2 mice models showed high tumor/muscle ratios 96 h p.i.with[^(89)Zr]Zr-DFO-TST001 was much higher than those of the other imaging groups.Immunohistochemistry results showed that BGC823CLDN18.2 tumors were highly positive(+++)for CLDN18.2,while those in the BGC823 group did not express CLDN18.2().The results of ex vivo biodistribution studies showed that there was a higher distribution in the BGC823CLDN18.2 tumor bearing mice(2.05±0.16%ID/g)than BGC823 mice(0.69±0.02%ID/g)and blocking group(0.72±0.02%ID/g).A dosimetry estimation study showed that the effective dose of[^(89)Zr]Zr-DFO-TST001 was 0.0705 mSv/MBq,which is within the range of acceptable doses for nuclear medicine research.Taken together,these results suggest that Good Manufacturing Practices produced by this immuno-positron emission tomography probe can detect CLDN18.2-overexpressing tumors.Yan Chen Xingguo Hou Dapeng Li Jin Ding Jiayue Liu Zilei Wang Fei Teng Hongjun Li Fan Zhang Yi Gu Steven Yu Xueming Qian Zhi Yang Hua Zhu 2023Journal of Pharmaceutical Analysis2023,13,4:2
15High-precision gyro-stabilized control of a gear-driven platform with a floating gear tension device显示文摘This study presents an improved compound control algorithm that substantially enhances the antidisturbance performance of a gear-drive gyro-stabilized platform with a floating gear tension device.The tension device can provide a self-adjustable preload to eliminate the gap in the meshing process.However,the weaker gear support stiffness and more complex meshing friction are also induced by the tension device,which deteriorates the control accuracy and the ability to keep the aim point of the optical sensors isolated from the platform motion.The modeling and compensation of the induced complex nonlinearities are technically challenging,especially when base motion exists.The aim of this research is to cope with the unmeasured disturbances as well as the uncertainties caused by the base lateral motion.First,the structural properties of the gear transmission and the friction-generating mechanism are analyzed,which classify the disturbances into two categories:Time-invariant and time-varying parts.Then,a proportional-integral controller is designed to eliminate the steady-state error caused by the time-invariant disturbance.A proportional multiple-integral-based state augmented Kalman filter is proposed to estimate and compensate for the time-varying disturbance that can be approximated as a polynomial function.The effectiveness of the proposed compound algorithm is demonstrated by comparative experiments on a gear-drive pointing system with a floating gear tension device,which shows a maximum 76%improvement in stabilization precision.Xianliang JIANG Dapeng FAN Shixun FAN Xin XIE Ning CHEN 2021Frontiers of Mechanical Engineering2021,16,3:1
16Significant coal combustion contribution to water-soluble brown carbon during winter in Xingtai, China: Optical properties and sources显示文摘To understand the characteristics of atmospheric brown carbon(BrC),daily PM2.5 samples in Xingtai,a small city in North China Plain(NCP),during the four seasons of 2018-2019,were collected and analyzed for optical properties and chemical compositions.The light absorption at 365 nm(abs λ=365 nm)displayed a strong seasonal variation with the highest value in winter(29.0±14.3 M/m),which was 3.2∼5.4-fold of that in other seasons.A strong correlation of abs λ=365 nm with benzo(b)fluoranthene(BbF)was only observed in winter,indicating that coal combustion was the major source for BrC in the season due to the enhanced domestic heating.The mass absorbing efficiency of BrC also exhibited a similar seasonal pattern,and was found to correlate linearly with the aerosol pH,suggesting a positive effect of aerosol acidity on the optical properties and formation of BrC in the city.Positive matrix factorization(PMF)analysis further showed that on a yearly basis the major source for BrC was biomass burning,which accounted for 34% of the total BrC,followed by secondary formation(26.7%),coal combustion(21.3%)and fugitive dust(18%).However,the contribution from coal combustionwas remarkably enhanced in winter,accounting for∼40%of the total.Our work revealed that more efforts of“shifting coal to clean energy”are necessary in rural areas and small cities in NCP in order to further mitigate PM2.5 pollution in China.Dapeng Li Can Wu Si Zhang Yali Lei Shaojun Lv Wei Du Shijie Liu Fan Zhang Xiaodi Liu Lang Liu Jingjing Meng Yuesi Wang Jian Gao Gehui Wang 2023Journal of Environmental Sciences2023,,2:1
