| 2 | Deep Reinforcement Learning Based Approach for Optimal Power Flow of Distribution Networks Embedded with Renewable Energy and Storage Devices显示文摘This study proposes a deep reinforcement learning(DRL)based approach to analyze the optimal power flow(OPF)of distribution networks(DNs)embedded with renewable energy and storage devices.First,the OPF of the DN is formulated as a stochastic nonlinear programming problem.Then,the multi-period nonlinear programming decision problem is formulated as a Markov decision process(MDP),which is composed of multiple single-time-step sub-problems.Subsequently,the state-of-the-art DRL algorithm,i.e.,proximal policy optimization(PPO),is used to solve the MDP sequentially considering the impact on the future.Neural networks are used to extract operation knowledge from historical data offline and provide online decisions according to the real-time state of the DN.The proposed approach fully exploits the historical data and reduces the influence of the prediction error on the optimization results.The proposed real-time control strategy can provide more flexible decisions and achieve better performance than the pre-determined ones.Comparative results demonstrate the effectiveness of the proposed approach. | Di Cao Weihao Hu Xiao Xu Qiuwei Wu Qi Huang Zhe Chen Frede Blaabjerg | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，5： | 4 |
| 3 | Air pollution and inhalation exposure to particulate matter of different sizes in rural households using improved stoves in central China显示文摘Household air pollution is considered to be among the top environmental risks in China.To examine the performance of improved stoves for reduction of indoor particulate matter(PM) emission and exposure in rural households, individual inhalation exposure to size-resolved PM was investigated using personal portable samplers carried by residents using wood gasifier stoves or improved coal stoves in a rural county in Central China.Concentrations of PM with different sizes in stationary indoor and outdoor air were also monitored at paired sites. The stationary concentrations of size-resolved PM in indoor air were greater than those in outdoor air, especially finer particles PM0.25. The daily averaged exposure concentrations of PM0.25, PM1.0, PM2.5 and total suspended particle for all the surveyed residents were 74.4 ± 41.1, 159.3 ± 74.3, 176.7 ± 78.1 and 217.9 ± 78.1 μg/m3,respectively. Even using the improved stoves, the individual exposure to indoor PM far exceeded the air quality guideline by WHO at 25 μg/m3. Submicron particles PM1.0 were the dominant PM fraction for personal exposure and indoor and outdoor air. Personal exposure exhibited a closer correlation with indoor PM concentrations than that for outdoor concentrations. Both inhalation exposure and indoor air PM concentrations in the rural households with gasifier firewood stoves were evidently lower than the reported results using traditional firewood stoves. However, local governments in the studied rural areas should exercise caution when widely and hastily promoting gasifier firewood stoves in place of improved coal stoves, due to the higher PM levels in indoor and outdoor air and personal inhaled exposure. | Weijian Liu Guofeng Shen Yuanchen Chen Huizhong Shen Ye Huang Tongchao Li Yilong Wang Xiaofang Fu Shu Tao Wenxin Liu Yibo Huang-Fu Weihao Zhang Chunyu Xue Guangqing Liu Fuyong Wu Minghung Wong | 2018 | Journal of Environmental Sciences2018，30，1： | 4 |
| 4 | A beam position measurement system of fully digital signal processing at SSRF显示文摘This fully digital beam position measurement instrument is designed for beam position monitoring and machine research in Shanghai Synchrotron Radiation Facility. The signals received from four position-sensitive detectors are narrow pulses with a repetition rate up to 499.654 MHz and a pulse width of around 100 ps, and their dynamic range could vary over more than 40 dB in machine research. By the employment of the under-sampling technique based on high-speed high-resolution A/D conversion, all the processing procedure is performed fully by the digital signal processing algorithms integrated in one single Field Programmable Gate Array. This system functions well in the laboratory and commissioning tests, demonstrating a position resolution (at the turn by turn rate of 694 kHz) better than 7 μm over the input amplitude range of -40 dBm to 10 dBm which is well beyond the requirement. | YAN Han ZHAO Lei LIU Shubin CHEN Kat WU Weihao AN Qi LENG Yongbin YI Xing YAN Yingbing LAI Longwei | 2012 | Nuclear Science and Techniques2012，23，2： | 3 |

| 6 | Safety and efficacy of a modified XELOX adjuvant regimen for patients with operated stage III colon cancer:a Chinese single-center experience显示文摘Background:A fixed 8-cycle oxaliplatin and capecitabine(XELOX)regimen has been the standard adjuvant therapy for patients with stage III colon cancer.However,completing the full-cycle of oxaliplatin is often associated with severe neurotoxicity.To spare patients from the toxic effects,without comprising the required efficacy,we evaluated the safety and efficacy of a modified XELOX(mXELOX)adjuvant chemotherapy regimen with 6 cycles of oxaliplatin and a full cycle of capecitabine.Methods:We retrospectively analyzed 330 eligible patients with stage III colon cancer who underwent cura-tive tumor resection followed by mXELOX,standard XELOX or unfinished XELOX adjuvant chemotherapy between December 2007 and April 2015.Associated prognostic factors were investigated and their disease-free survival(DFS)and overall survival(OS)rates were also determined and compared among the different regimen groups.Results:Compared with the standard XELOX group,the mXELOX group had lower total incidence rates of neuro-toxicity(39.3%vs.76.2%,P<0.001),leucopenia(53.6%vs.69.8%,P=0.017)and thrombocytopenia(38.1%vs.56.3%,P=0.011).The standard XELOX and mXELOX adjuvant chemotherapy regimens presented with comparable 3-year DFS rates(86.3%vs.89.2%;P=0.838)and 3-year OS rates(92.7%vs.97.6%;P=0.227).Compared to unfinished XELOX chemotherapy,the oncologic benefits of the mXELOX regimen were greater for patients with T4 tumors(3-year DFS:Hazard ratio[HR],2.184;95%confidence interval[CI],1.051-4.540;P=0.036;3-year OS:HR,4.529;95%CI 1.245-16.479;P=0.022)and for high-risk patients(3-year DFS:HR,1.962;95%CI 0.964-3.993;P=0.044;3-year OS:HR,4.193;95%CI 1.182-14.874;P=0.026).Conclusions:The mXELOX adjuvant chemotherapy presented a comparable survival benefit and lower incidence of toxicity than standard XELOX chemotherapy.It could be an alternative treatment for high-risk patients with operated stage III colon cancer. | Jianhong Peng Weihao Li Rongxin Zhang Junzhong Lin Jinghua Tang Yongshan Wen Zhenhai Lu Xiaojun Wu Zhizhong Pan | 2019 | Cancer Communications2019，39，1： | 2 |
| 7 | Enhancing carrier transport in flexible CZTSSe solar cells via doping Li strategy显示文摘The passivation of non-radiative states and inhibition of band tailings are desirable for improving the open-circuit voltage(V_(oc))of CZTSSe thin-film solar cells.Recently,alkali metal doping has been investigated to passivate defects in CZTSSe films.Herein,we investigate Li doping effects by applying Li OH into CZTSSe precursor solutions,and verify that carrier transport is enhanced in the CZTSSe solar cells.Systematic characterizations demonstrate that Li doping can effectively passivate non-radiative recombination centers and reduce band tailings of the CZTSSe films,leading to the decrease in total defect density and the increase in separation distance between donor and acceptor.Fewer free carriers are trapped in the band tail states,which speeds up carrier transport and reduces the probability of deep-level defects capturing carriers.The charge recombination lifetime is about twice as long as that of the undoped CZTSSe device,implying the heterojunction interface recombination is also inhibited.Besides,Li doping can increase carrier concentration and enhance build-in voltage,leading to a better carrier collection.By adjusting the Li/(Li+Cu)ratio to 18%,the solar cell efficiency is increased significantly to 9.68%with the fill factor(FF)of 65.94%,which is the highest FF reported so far for the flexible CZTSSe solar cells.The increased efficiency is mainly attributed to the reduction of V_(oc)deficit and the improved CZTSSe/Cd S junction quality.These results open up a simple route to passivate non-radiative states and reduce the band tailings of the CZTSSe films and improve the efficiency of the flexible CZTSSe solar cells. | Qiong Yan Quanzhen Sun Hui Deng Weihao Xie Caixia Zhang Jionghua Wu Qiao Zheng Shuying Cheng | 2022 | Journal of Energy Chemistry2022，，12： | 2 |
| 8 | Revealing structural degradation in layered structure oxides cathode of lithium ion batteries via in-situ transmission electron microscopy显示文摘Transition metal oxides with layered structure have been widely used as cathode materials for lithium-ion batteries(LIBs)which have relatively high energy density,large capacity and long life.However,in the long-term electrochemical cycle,the inevitable degradation of performance of LIBs due to structural degradation in cathodes severely restricts their large-scale practical applications.Understanding the underlying mechanism of structural degradation is the most critical scientific problem.Recently,in situ transmission electron microscopy(TEM)has become a useful tool to study the structural and compositional evolutions at atomic scale in electrochemical reactions,which provided a unique and in-depth understanding of the structural degradation.In this review,we discuss the recent advances in the in situ TEM,focusing on its role in revealing the structural degradation mechanisms in the four key places:(1)the interface between the cathodes and electrolyte;(2)the cathode surface;(3)the particle interior and(4)those induced by thermal effect.The insight gained by the in-situ TEM which is still developing at its fast pace is unique and expected to provide guidance for designing better layered cathode materials. | Fanjie Xia Weihao Zeng Haoyang Peng Hong Wang Congli Sun Ji Zou Jinsong Wu | 2023 | Journal of Materials Science & Technology2023，，23： | 1 |
| 9 | In situ generated layered NiFe-LDH/MOF heterostructure nanosheet arrays with abundant defects for efficient alkaline and seawater oxidation显示文摘As the main limiting step of overall water splitting,oxygen evolution reaction(OER)is urgent to be enhanced by developing efficient catalysts to promote the process of electrolytic water.Based on theoretical analysis,the Ni-metal-organic framework(Ni-MOF)and NiFe-layered double hydroxide(NiFe-LDH)(NiFe-LDH/MOF)heterostructure can optimize the energy barrier of the OER process and decrease the adsorption energy of oxygen-containing intermediates,effectively accelerating the OER kinetics.Accordingly,layered NiFe-LDH/MOF heterostructures are in situ constructed through a facile two-step reaction process,with substantial oxygen defects and lattice defects that further improve the catalytic performance.As a result,only 208 and 275 mV OER overpotentials are needed for NiFe-LDH/MOF to drive the current densities of 20 and 100 mA·cm^(-2)in 1 M KOH solutions,and even maintain catalytic stability of 100 h at 20 mA·cm^(-2).When applied to seawater oxidation,only 235 and 307 mV OER overpotentials are required to achieve the current densities of 20 and 100 mA·cm^(-2),respectively,with almost no attenuation for 100 h stability test at 20 mA·cm^(-2),all better than commercial RuO_(2).This work provides the theoretical and experimental basis and a new idea for efficiently driving fresh water and seawater cracking by heterostructure and defect coupling design toward catalysts. | Manjie Xiao Can Wu Jiawei Zhu Chengtian Zhang Yan Li Jiahui Lyu Weihao Zeng Haiwen Li Lei Chen Shichun Mu | 2023 | Nano Research2023，16，7： | 1 |
| 10 | Homer1a reduces inflammatory response after retinal ischemia/reperfusion injury显示文摘Elevated intraocular pressure(IOP)is one of the causes of retinal ischemia/reperfusion injury,which results in NRP3 inflammasome activation and leads to visual damage.Homerla is repo rted to play a protective role in neuroinflammation in the cerebrum.However,the effects of Homerla on NLRP3inflammasomes in retinal ischemia/reperfusion injury caused by elevated IOP remain unknown.In our study,animal models we re constructed using C57BL/6J and Homer1^(flox/-)/Homerla^(+/-)/Nestin-Cre^(+/-)mice with elevated IOP-induced retinal ischemia/repe rfusion injury.For in vitro expe riments,the oxygen-glucose deprivation/repe rfusion injury model was constructed with M uller cells.We found that Homerla ove rexpression amelio rated the decreases in retinal thickness and Muller cell viability after ischemia/reperfusion injury.Furthermore,Homerla knockdown promoted NF-κB P65^(Ser536)activation via caspase-8,NF-κB P65 nuclear translocation,NLRP3 inflammasome formation,and the production and processing of interleukin-1βand inte rleukin-18.The opposite results we re observed with Homerla ove rexpression.Finally,the combined administration of Homerla protein and JSH-23 significantly inhibited the reduction in retinal thickness in Homer1^(flox/-)Homer1a^(+/-)/Nestin-Cre^(+/-)mice and apoptosis in M uller cells after ischemia/reperfusion injury.Taken together,these studies demonstrate that Homer1a exerts protective effects on retinal tissue and M uller cells via the caspase-8/NF-KB P65/NLRP3 pathway after I/R injury. | Yanan Dou Xiaowei Fei Xin He Yu Huan Jialiang Wei Xiuquan Wu Weihao Lyu Zhou Fei Xia Li Fei Fei | 2024 | Neural Regeneration Research2024，19，7： | 0 |
| 11 | Constraining self-interacting dark matter with the full dataset of PandaX-II显示文摘Self-interacting dark matter(SIDM)is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxies.Many SIDM models predict the existence of a light force carrier that mediates strong dark matter self-interactions.If the mediator couples to the standard model particles,it could produce characteristic signals in dark matter direct detection experiments.We report searches for signals of SIDM models with a light mediator using the full dataset of the PandaX-II experiment,basing on a total exposure of 132 tonne-days.No significant excess over background is found,and our likelihood analysis leads to a strong upper limit on the dark matter-nucleon coupling strength.We further combine the PandaX-II constraints and those from observations of the light element abundances in the early universe,and show that direct detection and cosmological probes can provide complementary constraints on dark matter models with a light mediator. | Jijun Yang Abdusalam Abdukerim Wei Chen Xun Chen Yunhua Chen Chen Cheng Xiangyi Cui Yingjie Fan Deqing Fang Changbo Fu Mengting Fu Lisheng Geng Karl Giboni Linhui Gu Xuyuan Guo Ke Han Changda He Shengming He Di Huang Yan Huang Ran Huo Yanlin Huang Zhou Huang Xiangdong Ji Yonglin Ju Shuaijie Li Qing Lin Huaxuan Liu Jianglai Liu Xiaoying Lu Wenbo Ma Yugang Ma Yajun Mao Yue Meng Nasir Shaheed Kaixiang Ni Jinhua Ning Xuyang Ning Xiangxiang Ren Changsong Shang Guofang Shen Lin Si Andi Tan Anqing Wang Hongwei Wang Meng Wang QiuHong Wang Siguang Wang Wei Wang Xiuli Wang Zhou Wang Mengmeng Wu Shiyong Wu Weihao Wu Jingkai Xia Mengjiao Xiao Xiang Xiao Pengwei Xie Binbin Yan Yong Yang Chunxu Yu Hai-Bo Yu Jumin Yuan Ying Yuan Xinning Zeng Dan Zhang Tao Zhang Li Zhao Qibin Zheng Jifang Zhou Ning Zhou Xiaopeng Zhou | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，11： | 0 |

| 13 | In-doping collaboratively controlling back interface and bulk defects to achieve efficient flexible CZTSSe solar cells显示文摘Focusing on the low open circuit voltage(V_(OC))and fill factor(FF)in flexible Cu_(2)ZnSn(S,Se)_(4)(CZTSSe)solar cells,indium(In)ions are introduced into the CZTSSe absorbers near Mo foils to modify the back interface and passivate deep level defects in CZTSSe bulk concurrently for improving the performance of flexible device.The results show that In doping effectively inhibits the formation of secondary phase(Cu(S,Se)_(2))and VSndefects.Further studies demonstrate that the barrier height at the back interface is decreased and the deep level defects(Cu_(Sn)defects)in CZTSSe bulk are passivated.Moreover,the carrier concentration is increased and the V_(OC) deficit(V_(OC,def))is decreased significantly due to In doping.Finally,the flexible CZTSSe solar cell with 10.01%power conversion efficiency(PCE)has been obtained.The synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new thought for the fabrication of efficient flexible kesterite-based solar cells. | Quanzhen Sun Yifan Li Caixia Zhang Shunli Du Weihao Xie Jionghua Wu Qiao Zheng Hui Deng Shuying Cheng | 2024 | Journal of Energy Chemistry2024，89，2： | 0 |

| 15 | Genomic evolution during locoregional recurrence in colorectal cancer determined by whole-exome sequencing: a retrospective observational study显示文摘Objective:The genomic landscapes of metastatic colorectal cancer(mCRC)have been extensively studied;however,the genetic mechanisms underlying the locoregional recurrence(LR)of CRC remain unclear.The objective of our study was to investigate genomic evolution during LR in CRC using high-throughput sequencing.Methods:Twenty-three CRC patients with matched primary and LR tissues were recruited from Nanfang Hospital and Zhejiang Cancer Hospital between January 2011 and December 2018.The last date of follow-up was March 2020.Tissue samples were analyzed by whole-exome sequencing and the genomic profiles were depicted by single nucleotide variation,mutational signature,copy number variation,clonal architecture,and other features.The evolutionary process was speculated with comparison of the genetic variations between primary and LR lesions.The disseminating clusters from primary to LR lesions were identified by variant allele frequency dynamics.Furthermore,the early-recurrent biomarker was explored by comparing the indel signature between early-and late-recurrent patients.The study was approved by the Institutional Review Board of Nanfang Hospital of Southern Medical University(approval No.2020010)on September 11,2020.Results:The results highlighted distinct origins of LR between patients with high microsatellite instability and microsatellite stability.LR lesions evolved independently in patients with high microsatellite instability,while LR lesions were highly clonally related to the primary lesions in patients with microsatellite stability.Late-acquired variations in LR lesions encompassed a wide range of driver genes involved in histone methylation,DNA replication,T cell activation,PDCD1 gain,and LMNA loss.Furthermore,clonal analysis of the disseminating cells identified a dominant polyclonal seeding pattern during LR.The indel signature ID4 was associated with significantly shorter disease-free survival in patients with relapsed CRC according to a public dataset.Conclusion:These findings pose a challenge for the development of new approaches targeting the interactions of multiple clones in the establishment of LR and in terms of optimizing the clinical management of susceptible patients. | Xiaoliang Lan Xiaoxiao Wu Chao Zhang Genxia Wei Bingbing Li Weihao Qiu Danyi Li Huanwen Wu Yanqing Ding Jie Yuan Zaixian Tai Zuoquan Yang Zhiyong Liang Dan Su Li Liang | 2022 | Journal of Bio-X Research2022，5，4： | 0 |

| 17 | Double Z-Scheme g-C_(3)N_(4)/BiOI/CdS heterojunction with I_(3)^(-)/I^(-) pairs for enhanced visible light photocatalytic performance显示文摘The g-C_(3)N_(4)/BiOI/CdS double Z-scheme heterojunction photocatalyst with I_(3)^(-)/I^(-) redox pairs is prepared using simple calcination,solvothermal,and solution chemical deposition methods.The photocatalyst comprised mesoporous,thin g-C_(3)N_(4) nanosheets loaded on flower-like microspheres of BiOI with CdS quantum dots.The g-C_(3)N_(4)/BiOI/CdS double Z-scheme heterojunction has abundant active sites and in situ redox I_(3)^(-)/I^(-) mediators and shows quantum size effects,which are all conducive to enhancing the separation of photoinduced charges and increasing the photocatalytic degradation efficiency for bisphenol A,a model pollutant.Specifically,the heterojunction photocatalyst achieves a photocatalytic degradation efficiency for bisphenol A of 98.62%in 120 min and photocatalytic hydrogen production of 863.44 mmol h^(-1) g^(-1) on exposure to visible light.The excellent visible-light photocatalytic performance is as a result of the Z-scheme heterojunction,which extends absorption to the visible light region,as well as the I_(3)^(-)/I^(-) pairs,which accelerate photoinduced charge carrier transfer and separation,thus dramatically boosting the photocatalytic performance.In addition,the key role of the charge transfer across the indirect Z-scheme heterojunction has been elucidated and the transfer mechanism is confirmed based on the detection of intermediate I_(3)^(-)ions.Thus,this study provides guidelines for the design of indirect Z-scheme heterojunction photocatalysts. | Yan Zhang Yixiao Wu Liang Wan Wenfeng Yang Huijun Ding Chongyang Lu Weihao Zhang Zipeng Xing | 2022 | Green Energy & Environment2022，7，6： | 0 |
| 18 | Boron nitride-enabled printing of a highly sensitive and flexible iontronic pressure sensing system for spatial mapping显示文摘Recently,flexible iontronic pressure sensors(FIPSs)with higher sensitivities and wider sensing ranges than conventional capacitive sensors have been widely investigated.Due to the difficulty of fabricating the nanostructures that are commonly used on electrodes and ionic layers by screen printing techniques,strategies for fabricating such devices using these techniques to drive their mass production have rarely been reported.Herein,for the first time,we employed a 2-dimensional(2D)hexagonal boron nitride(h-BN)as both an additive and an ionic liquid reservoir in an ionic film,making the sensor printable and significantly improving its sensitivity and sensing range through screen printing.The engineered sensor exhibited high sensitivity(S_(min)>261.4 kPa^(−1))and a broad sensing range(0.05-450 kPa),and it was capable of stable operation at a high pressure(400 kPa)for more than 5000 cycles.In addition,the integrated sensor array system allowed accurate monitoring of wrist pressure and showed great potential for health care systems.We believe that using h-BN as an additive in an ionic material for screen-printed FIPS could greatly inspire research on 2D materials for similar systems and other types of sensors. | Zekun Yang Qikai Duan Junbin Zang Yunlong Zhao Weihao Zheng Ran Xiao Zhidong Zhang Liangwei Hu Guirong Wu Xueli Nan Zengxing Zhang Chenyang Xue Libo Gao | 2023 | Microsystems & Nanoengineering2023，9，3： | 0 |
| 19 | Coordinated voltage control of renewable energy power plants in weak sending-end power grid显示文摘The utilization of renewable energy in sending-end power grids is increasing rapidly,which brings difficulties to voltage control.This paper proposes a coordinated voltage control strategy based on model predictive control(MPC)for the renewable energy power plants of wind and solar power connected to a weak sending-end power grid(WSPG).Wind turbine generators(WTGs),photovoltaic arrays(PVAs),and a static synchronous compensator are coordinated to maintain voltage within a feasible range during operation.This results in the full use of the reactive power capability of WTGs and PVAs.In addition,the impact of the active power outputs of WTGs and PVAs on voltage control are considered because of the high R/X ratio of a collector system.An analytical method is used for calculating sensitivity coefficients to improve computation efficiency.A renewable energy power plant with 80 WTGs and 20 PVAs connected to a WSPG is used to verify the proposed voltage control strategy.Case studies show that the coordinated voltage control strategy can achieve good voltage control performance,which improves the voltage quality of the entire power plant. | Yongning Chi Weihao Li Qiuwei Wu Chao Liu | 2020 | Global Energy Interconnection2020，3，4： | 0 |
