| 1 | A fast boundary protection for an AC transmission line connected to an LCCHVDC inverter station显示文摘For AC transmission lines connected to an LCC-HVDC inverter station,commutation failure can lead to the wrong operation of traditional protection.To solve the problem,this paper proposes a fast protection scheme using transient information from one end of the AC line.The boundary frequency characteristics of the AC line connected to LCC-HVDC inverter are analyzed first.This reveals the existence of significant attenuation on both high frequency signals and some specific frequency signals.Based on the boundary characteristics,a novel boundary protection principle utilizing a backward traveling wave is then proposed.A PSCAD/EMTDC simulation model of a±800 kV LCC-HVDC and 500 kV AC transmission system is established,and different fault cases are simulated.The simulation results prove that the novel protection principle is immune to commutation failure,fault resistance and fault type. | Zhen Liu Houlei Gao Sibei Luo Le Zhao Yuyao Feng | 2020 | Protection and Control of Modern Power Systems2020，5，1： | 2 |
| 2 | The Application of Quality Control Circles to Reduce the Cost of Non-priced Consumables in Department of Oncology显示文摘Objective:To investigate the effectiveness of using quality control circle(QCC)techniques to reduce the cost of non-priced consumables in medical oncology.Methods:Analytic statistics were compiled on the performance appraisal form.Aiming at the key points of improvement with respect to the excess cost of non-valuable consumables,the reasons were analyzed,and corresponding measures were formulated to compare the cost before and after the improvement.Results:After the QCC activity,the cost of non-priced consumables decreased from RMB 6.57/bed day to RMB 3.96/bed day.Conclusion:QCC has effectively reduced the cost of non-priced consumables in the oncology department,and it is worthy of promotion. | Xiaofang Zhang Jinglan Luo Rui Dai Lu Wang Jieli Wei Yingying Liang Qiugui Huang Yuyao Liu | 2021 | Journal of Clinical and Nursing Research2021，5，3： | 0 |
| 3 | Human SIDT1 mediates dsRNA uptake via its phospholipase activity显示文摘Dear Editor,Systemic RNA interference(RNAi)refers to post-transcriptional gene silencing that spreads throughout the organism and its progeny,which could be triggered by double-stranded(ds)RNA.^(1,2)Hunter and colleagues identified that a ubiquitously expressed putative transmembrane protein SID-1(systemic RNAi defective-1)in Caenorhabditis elegans is required for systemic RNA(3). | Cai-Rong Sun Da Xu Fengrui Yang Zhuanghao Hou Yuyao Luo Chen-Yu Zhang Ge Shan Guangming Huang Xuebiao Yao Yuxing Chen Qiong Li Cong-Zhao Zhou | 2024 | Cell Research2024，34，1： | 0 |
| 4 | Optimal Scheduling of Distribution Network Incorporating Topology Reconfiguration,Battery Energy System and Load Response显示文摘Distributed generation(DG)is becoming increasingly important due to the serious environmental pollution caused by conventional fossil-energy-based generation and the depletion of non-renewable energy.As the flexible resources in the active distribution network(ADN),battery energy system(BES)and responsive load(RL)are all able to assist renewable DG integration in day-ahead dispatch.In addition,the security and economic level can be significantly improved by adjusting network topology.Therefore,in this paper,a coordinated day-ahead scheduling method incorporating topology reconfiguration,BES optimization and load response is presented to minimize the total day-ahead operational costs in the ADN.Linearized current injection models are presented for renewable DG,RL and BES based on the linear power flow model,and an extensible linear switching operations calculation(ELSOC)method is proposed to address the network reconfiguration.Thus,a mixed integer linear programming(MILP)model is proposed for optimal coordinated operation of an ADN.The correctness and effectiveness of the proposed method are demonstrated by simulations on a modified test system.In addition,the combined scenario and Monte-Carlo method is used to handle the uncertainties of loads and DGs,and the results of different uncertainties can further verify the feasibility of the proposed model. | Xuebo Qiao Yuyao Luo Juanxia Xiao Yong Li Li Jiang Xia Shao Jiazhu Xu Yi Tan Yijia Cao | 2022 | CSEE Journal of Power and Energy Systems2022，8，3： | 0 |
| 5 | Laser direct writing of Ga_(2)O_(3)/liquid metal-based flexible humidity sensors显示文摘Flexible and wearable humidity sensors play a vital role in daily point-of-care diagnosis and noncontact human-machine interactions.However,achieving a facile and high-speed fabrication approach to realizing flexible humidity sensors remains a challenge.In this work,a wearable capacitive-type Ga_(2)O_(3)/liquid metal-based humidity sensor is demonstrated by a one-step laser direct writing technique.Owing to the photothermal effect of laser,the Ga_(2)O_(3)-wrapped liquid metal particles can be selectively sintered and converted from insulative to conductive traces with a resistivity of 0.19Ω·cm,while the untreated regions serve as active sensing layers in response to moisture changes.Under 95%relative humidity,the humidity sensor displays a highly stable performance along with rapid response and recover time.Utilizing these superior properties,the Ga_(2)O_(3)/liquid metal-based humidity sensor is able to monitor human respiration rate,as well as skin moisture of the palm under different physiological states for healthcare monitoring. | Songya Cui Yuyao Lu Depeng Kong Huayu Luo Liang Peng Geng Yang Huayong Yang Kaichen Xu | 2023 | Opto-Electronic Advances2023，6，7： | 0 |
