| 1 | Bi-level Coordinated Planning of Active Distribution Network Considering Demand Response Resources and Severely Restricted Scenarios显示文摘Due to the uncertainty and fluctuation of distributed generation(DG)and load,the operation of active distribution network(ADN)is affected by multi-dimension factors which are described by massive operation scenarios.Efficient and accurate screening of severely restricted scenarios(SRSs)has become a new challenge in ADN planning.In this paper,a novel bi-level coordinated planning model which combines the short-time-scale operation problem with the long-time-scale planning problem is proposed.At the upper level,the demand response(DR)resource,an effective non-component planning resource characterized by low capacity price,high energy price,and short contract term,is co-optimized with the configuration of lines and energy storage systems(ESSs)to achieve the economic trade-off between the investment cost and the operation cost under SRSs.At the lower level,with the planning scheme obtained from the upper level,massive operation problems are optimized to minimize the daily operation cost;and the SRSs are provided to the upper level through a shadow-price-based scenario screening method,which simulates the planning information(i.e.,the restricted degrees of operation scenarios)feedback process from ADN operators to ADN planners.Case studies on a 62-node distribution system in Jianshan New District,Zhejiang Province,China,illustrate the effectiveness of the proposed bi-level coordinated planning model considering DR resources and SRSs. | Huang Yixin Lin Zhenzhi Liu Xinyi Yang Li Dan Yangqing Zhu Yanwei Ding Yi Wang Qin | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，5： | 3 |
| 2 | Karyotype Analysis of Gazania rigens Varieties显示文摘For studying species origin, systematic evolution and phylogenetic relationship of Gazania rigens, four different G. rigens varieties, with different flower colors, were subjected to chromosome karyotype analysis. The somatic chromosome number in three varieties ‘Hongwen', ‘Xingbai'and ‘Richu' was 2n = 10, while in ‘Zhongguo Xunzhangju' it was 2n = 20. We speculate that the cardinal number of chromosomes in G. rigens plants is x = 5, in which case ‘Zhongguo Xunzhangju' is a tetraploid. The karyotype formulae of ‘Hongwen', ‘Xingbai' and ‘Richu' were 2n = 8m + 2sm,2n = 8m + 2sm and 2n = 10 m respectively. The karyotype formula of ‘Zhongguo Xunzhangju' was 2n = 18 m + 2sm. The asymmetrical karyotype coefficients of the four G. rigens varieties ranged from 53.80% to 58.84%. Only ‘Richu' had a ‘1A' karyotype, while the others were relatively symmetric ‘2A'. Karyotype analysis indicates that the three introduced varieties have a close genetic relationship. | ZENG Jiashi WANG Dongxu WU Yangqing GUO Xiaoyu ZHANG Yazhou LU Xiaoping | 2016 | Horticultural Plant Journal2016，2，5： | 3 |

| 6 | Longitudinal virological changes and underlying pathogenesis in hospitalized COVID-19 patients in Guangzhou,China显示文摘Prolonged viral RNA shedding and recurrence of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in coronavirus disease 2019(COVID-19)patients have been reported.However,the clinical outcome and pathogenesis remain unclear.In this study,we recruited 43 laboratory-confirmed COVID-19 patients.We found that prolonged viral RNA shedding or recurrence mainly occurred in severe/critical patients(P<0.05).The average viral shedding time in severe/critical patients was more than 50 days,and up to 100 days in some patients,after symptom onset.However,chest computed tomography gradually improved and complete absorption occurred when SARS-CoV-2 RT-PCR was still positive,but specific antibodies appeared.Furthermore,the viral shedding time significantly decreased when the A1,430G or C12,473T mutation occurred(P<0.01 and FDR<0.01)and increased when G227A occurred(P<0.05 and FDR<0.05).High IL1R1,IL1R2,and TNFRSF21 expression in the host positively correlated with viral shedding time(P<0.05 and false discovery rate<0.05).Prolonged viral RNA shedding often occurs but may not increase disease damage.Prolonged viral RNA shedding is associated with viral mutations and host factors. | Zhengtu Li Yinhu Li Ruilin Sun Shaoqiang Li Lingdan Chen Yangqing Zhan Mingzhou Xie Jiasheng Yang Yanqun Wang Airu Zhu Guoping Gu Le Yu Shuaicheng Li Tingting Liu Zhaoming Chen Wenhua Jian Qian Jiang Xiaofen Su Weili Gu Liyan Chen Jing Cheng Jincun Zhao Wenju Lu Jinping Zheng Shiyue Li Nanshan Zhong Feng Ye | 2021 | Science China(Life Sciences)2021，64，12： | 1 |

| 11 | Chronic Exposure to Environmentally Relevant Concentrations of Tetracycline Perturbs Gut Homeostasis in Zebrafish显示文摘The prevalence of residual antibiotics is a global threat to human health.Less is known about the potential health effects of residual antibiotics in freshwater systems.Here,zebrafish were used to explore chronic effects of environmentally relevant concentrations(ERCs)of tetracycline(TC).Although chronic exposure to TC did not significantly alter the body weight of adult zebrafish,the exposed zebrafish parents exhibited substantial changes in gut microbiota composition and a reduced gut-weight ratio.Notably,male fish exposed to TC showed a significant decline of critical intestinal function-related metabolites(i.e.,triglycerides,glucose,and free fat acid),while this was not observed in females,resulting in sex-dependency.The gut microbial composition of chronically exposed zebrafish parents changed substantially,but the disruption was not transferred to their respective offspring without exposure.However,the perturbation of insulinrelated signaling pathways caused by TC exposure was not attenuated in the zebrafish offspring after removal of TC exposure.Taken together,our findings suggest that chronic exposure to TC disturbs gut microbial communities and metabolism and exerts chronic effects on the insulin/IGF-1 mediated signaling cascades,implying that exposure to antibiotics not only leads to the selection of resistant microbes but also poses long-term deleterious health risks for the next generation. | Panpan Jia Shun Deng Xiaoxing Lin Liyan Song Yangqing Wang De-Sheng Pei | 2023 | Environment & Health2023，1，4： | 0 |
| 12 | Partition-based Network Equivalent Method for Power System Subsynchronous Oscillation Analysis显示文摘Given large-scale modern power systems with pow er electronic converters,the numerical simulation with subsyn chronous oscillation(SSO)faces great challenges in engineering practice due to sharply enlarged modeling scale and high com putational burden.To reduce the modeling scale,network parti tion and equivalent becomes a vital technique in numerical sim ulations.Although several methods have been developed for net work equivalent,a generally accepted rule for network parti tion is still required.This paper proposes that the system can be partitioned into three parts,i.e.,the internal,the middle,and the external subsystems,in which the internal subsystem consists of all power electronic components,the middle subsys tem includes those selected AC dynamic components with de tailed models,and the remaining components and buses consti tute the external subsystem.The external subsystem is further represented by an equivalent RLC network determined by the frequency dependent network equivalent(FDNE)method.In the proposed method,the observability index and the electrical distance index are used to identify the interface between the middle and the external subsystems.Case studies based on a modified Hydro-Quebec system are used to verify the effective ness of the proposed method. | Chenxuan Wang Weimin Zheng Zhen Wang Yangqing Dan Ping Ju | 2024 | Journal of Modern Power Systems and Clean Energy2024，12，1： | 0 |
| 13 | Physiochemical and biological characteristics of fouling on landfill leachate treatment systems surface显示文摘Fouling of landfill leachate,a biofilm formation process on the surface of the collection system,migration pipeline and treatment system causes low efficiency of leachate transportation and treatment and increases cost for maintenance of those facilities.In addition,landfill leachate fouling might accumulate pathogens and antibiotic resistance genes(ARGs),posing threats to the environment.Characterization of the landfill leachate fouling and its associated environmental behavior is essential for the management of fouling.In this study,physicochemical and biological properties of landfill leachate fouling and the possible accumulation capacity of pathogens and ARGs were investigated in nitrification(aerobic condition)and denitrification(anaerobic condition)process during landfill leachate biological treatment,respectively.Results show that microbial(bacterial,archaeal,eukaryotic,and viral)community structure and function(carbon fixation,methanogenesis,nitrification and denitrification)differed in fouling under aerobic and anaerobic conditions,driven by the supplemental leachate water quality.Aerobic fouling had a higher abundance of nitrification and denitrification functional genes,while anaerobic fouling harbored a higher abundance of carbon fixation and methanogenesis genes.Both forms of leachate fouling had a higher abundance of pathogens and ARGs than the associated leachate,suggesting the accumulation capacity of fouling on biotic pollutants.Specifically,aerobic fouling harbored three orders of magnitude higher multidrug resistance genes mex D than its associated leachate.This finding provides fundamental knowledge on the biological properties of leachate fouling and suggests that leachate fouling might harbor significant pathogens and ARGs. | Zhourui Gong Shu Yang Rui Zhang Yangqing Wang Xiaoqing Wu Liyan Song | 2024 | Journal of Environmental Sciences2024，，1： | 0 |
| 14 | Back Frame Section Size Optimization of Large Aperture Telescope显示文摘The back frame structure of a large radio telescope is an important component supporting the reflecting surface,which is directly related to the surface precision.Its optimal design is of key significance for ensuring the surface precision and reducing structural weight.Two methods are constructed to optimize the cross-section size of the telescope back frame in this paper,the criterion method and the first-order optimization method.The criterion method is based on the Lagrangian multiplier method and Kuhn-Tucker condition.This method first establishes the mathematical model by taking the inner and outer radiuses of the back frame beams as the design variables,the structural weight as the constraint condition,and the structural compliance as the objective function,then derives the optimization criterion.The first-order optimization method takes the inner and outer radiuses of the beams as the design variables,the back frame RMS as the objective function,and the structural weight as the constraint condition.Comparison of RMS,structural stress uniformity and optimization efficiency shows that both algorithms can effectively reduce structural deformation and improve RMS,but the criterion method has relatively better result than the first-order method. | Qinglong Wu Zhan Yao Tanhui Wu Yangqing Hou Huazhen Zhang Qian Xu Na Wang | 2023 | Journal of Harbin Institute of Technology(New Series)2023，30，4： | 0 |
