| 1 | The mechanism and risk factors for immune checkpoint inhibitor pneumonitis in non-small cell lung cancer patients显示文摘Immune checkpoint inhibitors(ICIs)are new and promising therapeutic agents for non-small cell lung cancer(NSCLC).However,along with demonstrating remarkable efficacy,ICIs can also trigger immune-related adverse events.Checkpoint inhibitor pneumonitis(CIP)has been reported to have a morbidity rate of 3%to 5%and a mortality rate of 10%to 17%.Moreover,the incidence of CIP in NSCLC is higher than that in other tumor types,reaching 7%to 13%.With the increased use of ICIs in NSCLC,CIP has drawn extensive attention from oncologists and cancer researchers.Identifying high risk factors for CIP and the potential mechanism of CIP are key points in preventing and monitoring serious adverse events.In this review,the results of our analysis and summary of previous studies suggested that the risk factors for CIP may include previous lung disease,prior thoracic irradiation,and combinations with other drugs.Our review also explored potential mechanisms closely related toCIP,including increasedT cell activity against associated antigens in tumor and normal tissues,preexisting autoantibodies,and inflammatory cytokines. | Xiaoyang Zhai Jian Zhang Yaru Tian Ji Li Wang Jing Hongbo Guo Hui Zhu | 2020 | Cancer Biology & Medicine2020，17，3： | 25 |
| 2 | A nowcasting model for the prediction of typhoon tracks based on a long short term memory neural network显示文摘It is of vital importance to reduce injuries and economic losses by accurate forecasts of typhoon tracks. A huge amount of typhoon observations have been accumulated by the meteorological department, however, they are yet to be adequately utilized. It is an effective method to employ machine learning to perform forecasts. A long short term memory(LSTM) neural network is trained based on the typhoon observations during 1949–2011 in China's Mainland, combined with big data and data mining technologies, and a forecast model based on machine learning for the prediction of typhoon tracks is developed. The results show that the employed algorithm produces desirable 6–24 h nowcasting of typhoon tracks with an improved precision. | GAO Song ZHAO Peng PAN Bin LI Yaru ZHOU Min XU Jiangling ZHONG Shan SHI Zhenwei | 2018 | Acta Oceanologica Sinica2018，37，5： | 17 |

| 4 | An Ethylene-inhibited NF-YC Transcription Factor RhNF-YC9 Regulates Petal Expansion in Rose显示文摘The speed of flower opening is closely related to their ornamental period.Ethylene functions as a negative regulator involved in the regulation of the petal expansion process.In this study,we isolated a NF-YC transcription factor gene,RhNF-YC9,fromrose petals.RhNF-YC9 expression was induced at the early stages of flower opening but was inhibited by ethylene treatment.Silencing RhNF-YC9 decreased the speed of petal expansion from stage 2 to stage 5.The expressions of 11 cell expansion-related genes involved in cell wall loosening,cell turgor modulation,and cytoskeleton remodeling were significantly down-regulated in RhNF-YC9-silenced petals.We also found that silencing RhNF-YC9 decreased the expression of gibberellin acid(GA)biosynthetic gene RhGA20ox while significantly increasing the transcripts of GA catabolic gene RhGA2ox,reducing the accumulation of GA4 and GA7.The influence of ethylene treatment on the expression of RhGA20ox and RhGA2ox showed the same trend.These results together suggested that RhNF-YC9 positively regulated the speed of petal expansion and mediated the crosstalk between ethylene and GA.Our findings revealed a new insight into the function of NF-YC transcription factors involved in ethylene-regulated petal expansion. | Changxi Chen Nisar Hussain Yaru Wang Mingtong Li Lin Liu Meizhu Qin Nan Ma Junping Gao Xiaoming Sun | 2020 | Horticultural Plant Journal2020，6，6： | 9 |
| 5 | Design,methodology,and baseline of whole city‑million scale children and adolescents myopia survey(CAMS)in Wenzhou,China显示文摘Background:Myopia is the most common visual impairment in children and adolescents worldwide.This study described an economical and effective population-based screening pipeline and performed the project of a million scale children and adolescents myopia survey(CAMS),which will shed light on the further study of myopia from the level of epidemiology and precision medicine.Methods:We developed a novel population-based screening pattern,an intelligent screening process and internetbased information transmission and analysis system to carry out the survey consisting of school children in Wenzhou,China.The examination items include unaided distance visual acuity,presenting distance visual acuity,and noncycloplegic autorefraction.Myopia and high myopia were defined as spherical equivalent(SE)≤−1.00 diopters(D)and SE≤−6.00 D,respectively.Next,the reports of the vision checking were automatically sent to parents and the related departments.The CAMS project will be done two to four times annually with the support of the government.An online eyesight status information management system(OESIMS)was developed to construct comprehensive and efficient electronic vision health records(EVHRs)for myopia information inquiry,risk pre-warning,and further study.Results:The CAMS completed the first-round of screening within 30 days for 99.41%of Wenzhou students from districts and counties,in June 2019.A total of 1,060,925 participants were eligible for CAMS and 1,054,251(99.37%participation rate)were selected through data quality control,which comprised 1305 schools,and 580,609,251,050 and 170,967 elementary,middle,and high school students.The mean age of participants was 12.21±3.32 years(6-20 years),the female-to-male ratio was 0.82.The prevalence of myopia in elementary,middle,and high school students was 38.16%,77.52%,and 84.00%,respectively,and the high myopia incidence was 0.95%,6.90%,and 12.98%.Conclusions:The CAMS standardized myopia screening model involves automating large-scale information collection,data transmission,data analysis and early warning,thereby supporting myopia prevention and control.The entire survey reduced 90%of staff,cost,and time consumption compared with previous surveys.This will provide new insights for decision support for public health intervention. | Liangde Xu Youyuan Zhuang Guosi Zhang Yunlong Ma Jian Yuan Changseng Tu MiaoMiao Li Wencan Wang Yaru Zhang Xiaoyan Lu Jing Li Xinting Liu Zhengbo Xue Meng Zhou Jie Sun Jinhua Bao Ming Li Fan Lu Hong Wang Jianzhong Su Jia Qu | 2021 | Eye and Vision2021，8，1： | 7 |
| 6 | Physical processes causing the formation of hypoxia off the Changjiang estuary after Typhoon Chan-hom, 2015显示文摘Severe hypoxia was observed in the submarine canyon to the east of the Changjiang estuary in July 14, 2015, two days after typhoon Chan-hom. The oxygen concentration reached as low as 2.0 mg/L and occupied a water column of about 25 m. A ROMS model was con?gured to explore the underlying physical processes causing the formation of hypoxia. Chan-hom passed through the Changjiang estuary during the neap tide. The strati?cation was completely destroyed in the shallow nearshore region when typhoon passing. However, it was maintained in the deep canyon, though the surface mixed layer was largely deepened. The residual water in the deep canyon is considered to be the possible source of the later hypoxia. After Chan-hom departure, not only the low salinity plume water spread further of fshore, but also the sea surface temperature(SST) rewarmed quickly. Both changes helped strengthen the strati?cation and facilitate the formation of hypoxia. It was found that the surface heat ?ux, especially the solar short wave radiation dominated the surface re-warming, the of fshore advection of the warmer Changjiang Diluted Water(CDW) also played a role. In addition to the residual water in the deep canyon, the Taiwan Warm Current(TWC) was found to ?ow into the deep canyon pre-and soon post-Chan-hom, which was considered to be the original source of the hypoxia water. | GUO Yaru RONG Zengrui LI Bo XU Zhao LI Pixue LI Xiaodan | 2019 | Journal of Oceanology and Limnology2019，37，1： | 5 |
| 7 | Microstructure and properties of novel Al-Ce-Sc,Al-Ce-Y,Al-Ce-Zr and Al-Ce-Sc-Y alloy conductors processed by die casting,hot extrusion and cold drawing显示文摘In order to overcome the trade-off between the strength and electrical conductivity of aluminum alloy conductors,the new Al-Ce-Sc,Al-Ce-Y,Al-Ce-Zr and Al-Ce-Sc-Y alloys were prepared by die casting,high temperature homogenization treatment,hot extrusion and cold drawing.Adding Sc and Y eliminated the dendrite segregation of the as-cast Al-0.2 Ce alloy and promoted the formation of equiaxed grains with the average grain size of 142.5μm.The Al-0.2 Ce-0.2 Sc-0.1 Y alloy inherited the great tensile properties of Al-0.2 Ce-0.2 Sc alloy and the high electrical conductivity of Al-0.2 Ce-0.1 Y alloy simultaneously.After cold drawing and annealing at 200℃for 5 h,the ultimate tensile strength of Al-0.2 Ce-0.2 Sc-0.1 Y alloy reached 200 MPa and 198 MPa,the elongation reached 6.8%and 8.5%,and the electrical conductivity reached 61.01%and 61.77%,respectively.The main second phase of Al-0.2 Ce-0.2 Sc-0.1 Y alloy after hot extrusion were Al_(13)Fe_3 Ce containing a few Y and Si atoms.The larger size and proportion of the second phase greatly reduced the concentration of solute Fe and Si atoms and the addition of Y significantly decreased the density of defects after cold drawing compared to Al-0.2 Ce-0.2 Sc alloy,which improved electrical conductivity of the alloy.Furthermore,the dispersed and coherent nano-size Al_3 Sc precipitions of Al-0.2 Ce-0.2 Sc-0.1 Y alloy greatly improved strength,elongation and heat resistance.Compared with Al-0.2 Ce-0.2 Sc alloy,the lower density of dislocation,stacking fault and subgrain boundary and the larger size of Al_3 Sc precipitions with enrichment of Y atoms enable the Al-0.2 Ce-0.2 Sc-0.1 Y alloy to maintain high strength,elongation and electrical conductivity after annealing. | Weiyi Wang Qinglin Pan Geng Lin Xiaoping Wang Yuqiao Sun Xiangdong Wang Ji Ye Yuanwei Sun Yi Yu Fuqing Jiang Jun Li Yaru Liu | 2020 | Journal of Materials Science & Technology2020，58，23： | 4 |
| 8 | A CuNi/C Nanosheet Array Based on a Metal–Organic Framework Derivate as a Supersensitive Non-Enzymatic Glucose Sensor显示文摘Bimetal catalysts are good alternatives for nonenzymatic glucose sensors owing to their low cost, high activity, good conductivity, and ease of fabrication. In the present study, a self-supported CuNi/C electrode prepared by electrodepositing Cu nanoparticles on a Ni-based metal–organic framework(MOF) derivate was used as a non-enzymatic glucose sensor. The porous construction and carbon scaffold inherited from the Ni-MOF guarantee good kinetics of the electrode process in electrochemical glucose detection. Furthermore, Cu nanoparticles disturb the array structure of MOF derived films and evidently enhance their electrochemical performances in glucose detection. Electrochemical measurements indicate that the CuNi/C electrode possesses a high sensitivity of17.12 mA mM^(-1) cm^(-2), a low detection limit of 66.67 nM,and a wider linearity range from 0.20 to 2.72 mM. Additionally, the electrode exhibits good reusability, reproducibility, and stability, thereby catering to the practical use of glucose sensors. Similar values of glucose concentrations in human blood serum samples are detected with our electrode and with the method involving glucose-6-phosphate dehydrogenase; the results further demonstrate the practical feasibility of our electrode. | Li Zhang Chen Ye Xu Li Yaru Ding Hongbo Liang Guangyu Zhao Yan Wang | 2018 | Nano-Micro Letters2018，10，2： | 4 |
| 9 | The enhanced protective effects of salvianic acid A: A functionalized nanoparticles against ischemic stroke through increasing the permeability of the blood-brain barrier显示文摘Ischemic stroke is the leading cause of disability and death worldwide. Currently, the only proven treatment for ischemic stroke is restoring the cerebral blood supply. In addition, some of the tissue is damaged during the subsequent reperfusion because of the overproduction of reactive oxygen species (ROS). Furthermore, antioxidant therapies have shown promise in preclinical studies for the treatment of ischemia-reperfusion injury. However, their therapeutic efficacy has been limited because of their low bioavailability in brain. To resolve this issue, we synthesized ROS-responsive, fan-shaped dendrimer nanoparticles (NPs) and conjugated them with a blood-brain barrier (BBB)-targeting peptide, COG1410, and salvianic acid A (SA), which is an effective antioxidant in ischemic stroke. The BBB targeting peptide acts as a ligand of the nanocarrier system and penetrates the BBB through the endocytosis of the ligand receptor. The results showed that T-SA-NPs not only target and accumulate in the infarct area, they also reduce over 2 times of the infarct area and reverse the behavioral deficits in MCAO mice, which illustrates that these NPs have an effective therapeutic effect on the ischemic stroke. In addition, these NPs had no toxicity in any organs of the body. Importantly, the present study provides an alternative strategy for delivering antioxidants to the brain and achieving targeted therapy of ischemic stroke. | Yaru Li Xiaojie Zhang Zhifeng Qi Xueling Guo Xiaopeng Liu Wenjuan Shi Yang Liu Libo Du | 2020 | Nano Research2020，13，10： | 4 |
| 10 | Exploration of particle technology in fine bubble characterization显示文摘Fine bubble technology has been applied in many fields, including semiconductor processing, waste water treatment, and agricultural development. Fine bubble technology has the advantages of being environ-mentally benign, and ease of production and use when compared with other processes that involve chemicals or biological agents. However, the mechanisms of fine bubble applications in many aspects still require exploration. The characterization of fine bubbles is one of the essential issues for better understanding the technology. This article reviews modern particle characterization technologies, espe-cially those that can be used to characterize fine bubbles, and briefly reports on some applications of fine bubbles. | Renliang Xu Yaru Wang Zhaojun Li | 2019 | Particuology2019，17，5： | 4 |
| 11 | LncRNA NORAD promotes the progression of myocardial infarction by targeting the miR-22-3p/PTEN axis显示文摘NORAD is a newly identified long non-coding RNA(lncRNA)that plays an important role in cancers.NORAD has been found to be highly expressed in the mouse model of acute myocardial infarction(AMI).However,the role of NORAD in the regulation of AMI remains unknown.In the present study,we aimed to investigate the function of NORAD in AMI and explore the potential regulatory mechanisms.A mouse model of AMI was established and NORAD was knocked-down.The infarcted size of heart tissues and the cardiac function were evaluated.In addition,two cardiomyocyte cell lines were treated with hypoxia/re-oxygenation(H/R)to mimic AMI in vitro.Luciferase reporter assay,RNA pull-down assay,fluorescence in situ hybridization,qRT-PCR,and western blot analysis were performed.Apoptotic cells and the levels of L-lactate dehydrogenase(LDH)and malondialdehyde(MDA)were detected.Our results show that downregulation of NORAD efficiently attenuates heart damage in the AMI mouse model.NORAD interacts with miR-22-3p.Knock-down of NORAD inhibits H/R-induced cell apoptosis and reduces LDH and MDA levels,while its effects are abolished by miR-22-3p inhibitor.MiR-22-3p interacts with PTEN and inhibits its expression.Overexpression of miR-22-3p inhibits H/R-induced cell apoptosis and reduces LDH and MDA levels,while its effects are abolished by overexpression of PTEN.Finally,overexpression of NORAD inhibits the AKT/mTOR signaling pathway,and its effects are attenuated by overexpression of miR-22-3p.Taken together,our study reveals that NORAD promotes the progression of AMI by regulating the miR-22-3p/PTEN axis,and the AKT/mTOR signaling may also be involved in the regulatory processes. | Chunxia Li Lihui Zhang Xingpeng Bu Guofang Chu Xiaofang Zhao Yaru Liu | 2022 | Acta Biochimica et Biophysica Sinica2022，54，4： | 3 |
| 12 | Hydrochemical characteristics and water quality evaluation of shallow groundwater in Suxian mining area,Huaibei coalfield,China显示文摘The aim of this study is to evaluate the hydrogeochemical characteristics and water environmental quality of shallow groundwater in the Suxian mining area of Huaibei coalfield,China.The natural formation process of shallow groundwater in Suxian is explored using Piper trilinear charts and Gibbs diagrams,and by examining the ratios between the major ions.United States Salinity Laboratory(USSL)charts,Wilcox diagrams,and the water quality index(WQI)are further employed to quantify the differences in water quality.The results reveal that the main hydrochemical facies of groundwater are HC03-Ca,and that silicate dissolution is the main factor controlling the ion content in shallow groundwater.The USSL charts and Wilcox diagrams show that most of the water samples would be acceptable for use in irrigation systems.The WQI results for each water sample are compared and analyzed,and the quality of groundwater samples around collapse ponds is found to be relatively poor. | Hao Yu Herong Gui Honghai Zhao Meichen Wang Jun Li Hongxia Fang Yaqi Jiang Yaru Zhang | 2020 | International Journal of Coal Science & Technology2020，7，4： | 3 |
| 13 | Geological controls of shale gas accumulation and enrichment mechanism in Lower Cambrian Niutitang Formation of western Hubei, Middle Yangtze, China显示文摘The lower Cambrian Niutitang Formation is of crucial importance for shale gas target reservoirs in western Hubei,China;however,little work has been done in this field,and its shale gas accumulation and enrichment mechanism are still unclear.Based on survey wells,outcrop data,and large numbers of tests,the geological conditions of shale gas accumulation were studied;moreover,the factors that influence the gas content were thoroughly discussed.The results show that the Niutitang Formation(Є1n)can be divided into three sections:the first section(Є_(1)n^(1)),the second section(Є_(1)n^(2)),and the third section(Є1n3).TheЄ_(1)n^(2) is the main shale gas reservoir.The deep shelf facies is the main sedimentary facies and can be divided into three main lithofacies:argillaceous siltstone,carbonaceous shale and carbonaceous siliceous rock.The total organic carbon(TOC)content shows gentle growth trends until bottom of theЄ_(1)n^(2) and then decreases rapidly within theЄ_(1)n^(1),and the TOC content mainly ranges from 2%to 4%horizontally.The calcite and dolomite dissolution pores,clay intergranular pores and organic pores are the main pore types and the micropore types are clearly related to the mineral compositions and the TOC content.Vertically,the gas content is mainly affected by the TOC content.Horizontally,wells with high gas contents are distributed only southeast of the Huangling anticline,and the combination of structural styles,fault and fracture development,and the distribution of the regional unconformity boundary between the upper Sinian Dengying Formation(Z2d)and theЄ_(1)n^(2) are the three most important factors affecting the gas content.The favorable areas must meet the following conditions:a deep shelf environment,the presence of theЄ_(1)n^(1),wide and gentle folds,far from large normal faults that are more than 5 km,moderate thermal evolution,and greater than 500 m burial depth;this includes the block with the YD2–ZD2 wells,and the block with the Y1 and YD4 wells,which are distributed in the southern portion of the Huangling anticline and northern portion of the Xiannvshan fault. | Lulu XU Saipeng HUANG Zaoxue LIU Yaru WEN Xianghui ZHOU Yanlin ZHANG Xiongwei LI Deng WANG Fan LUO Cheng CHEN | 2021 | Frontiers of Earth Science2021，15，2： | 3 |
| 14 | H2 solubility and mass transfer in anthraquinone working solution: Experimental and modeling study显示文摘This work was focused on the measurement of the solubility of hydrogen(H_2) in anthraquinone working solution at temperatures of 30.0–80.0 °C and pressures of 0.2–3.0 MPa by the method of experimental and COSMO-RS model study. The influence of various factors, i.e., including pressure, temperature and solvent volume ratio, on H_2 solubility was investigated. According to the experimental results, H_2 solubility in anthraquinone working solution increases with the increase of pressure. At low pressures, the temperature had little effect on H_2 solubility while under high pressures H_2 solubility increases with increasing temperature. Henry's constant lnH has a good linear relationship with 1/T(lnH =- 1319.1/T + 9.91). The effect of volume ratio of trioctyl phosphate to trimethylbenzene on the solubility of hydrogen was studied and the results showed that increasing the amount of trimethylbenzene was conducive to the dissolution of hydrogen. In addition, there is a linear relationship between ln((P0- Pe) /(Pt- Pe)) and the time t. Gas–liquid mass transfer coefficient was obtained by calculating the slope of the line. | Zhigang Lei Yaru Guo Yanyan Guo Xinxin Li Chengna Dai | 2017 | Chinese Journal of Chemical Engineering2017，25，2： | 2 |
| 15 | The BHLH Transcriptional Factor PIF4 Competes with the R2R3-MYB Transcriptional Factor MYB75 to Fine-Tune Seeds Germination under High Glucose Stress显示文摘It is known that the high level of sugar including glucose suppresses seed germination through ABA signal.ABI5 is an essential component to mediate ABA-dependent seed germination inhibition,but underlying mechanism needs more investigation.Previous study demonstrated the PIF4 activated the expression of ABI5 to suppress seed germination in darkness.Here we reported that PIF4 also mediated the seed germination inhibition through ABI5 under high concentration of glucose treatment.Furthermore,we found that PIF4 interacted with PAP1,the central factor to control anthocyanin biosynthesis.Such interaction was confirmed in vitro and in planta.Biochemical and physiological analysis revealed that PAP1 bond the promoter of ABI5 to suppress its expression,thus enhanced seed germination under high concentration of glucose treatment.Specially,PAP1 competed with PIF4 to antagonize the activation of PIF4 on ABI5 expression,thus promoted seed germination under high glucose treatment.Given these,we uncover a novel role for PIF4 and PAP1 in controlling seed germination under high glucose treatment,and reveal their antagonistic mechanism by which coordinates ABI5 expression to control seed germination in response to the glucose signal. | Xiaoli Li Shiyan Lu Yaru Yang Wenjie Wei Jiali Wei Xiaojun Yuan Ping Li | 2021 | Phyton-International Journal of Experimental Botany2021，90，5： | 2 |
| 16 | Understandings and future challenges in soybean functional genomics and molecular breeding显示文摘Soybean(Glycine max)is a major source of plant protein and oil.Soybean breeding has benefited from advances in functional genomics.In particular,the release of soybean reference genomes has advanced our understanding of soybean adaptation to soil nutrient deficiencies,the molecular mechanism of symbiotic nitrogen(N)fixation,biotic and abiotic stress tolerance,and the roles of flowering time in regional adaptation,plant architecture,and seed yield and quality.Nevertheless,many challenges remain for soybean functional genomics and molecular breeding,mainly related to improving grain yield through high-density planting,maize-soybean intercropping,taking advantage of wild resources,utilization of heterosis,genomic prediction and selection breeding,and precise breeding through genome editing.This review summarizes the current progress in soybean functional genomics and directs future challenges for molecular breeding of soybean. | Haiping Du Chao Fang Yaru Li Fanjiang Kong Baohui Liu | 2023 | Journal of Integrative Plant Biology2023，65，2： | 2 |

| 18 | Interannual Variability and Scenarios Projection of Sea Ice in Bohai Sea Part Ⅰ: Variation Characteristics and Interannual Hindcast显示文摘The Bohai Sea is one of the southernmost areas for sea ice formation in the northern hemisphere.Sea ice disasters in this body of water severely affect marine activities and the safety of coastal residents.In this study,we analyze the variation characteristics of the sea ice in the Bohai Sea and establish an annual regression model based on predictable mode analysis method.The results show the following:1)From 1970 to 2018,the average ice grade is(2.6±0.8),with a maximum of 4.5 and a minimum of 1.0.Liaodong Bay(LDB)has the heaviest ice conditions in the Bohai Sea,followed by Bohai Bay(BHB)and Laizhou Bay(LZB).Interannual variation is obvious in all three bays,but the linear decreasing trend is significant only in BHB.2)Three modes are obtained from empirical orthogonal function analysis,namely,single polarity mode with the same sign of anomaly in all of the three bays and strong interannual variability(82.0%),the north–south dipole mode with BHB and LZB showing an opposite sign of anomalies to that in LDB and strong decadal variations(14.5%),and a linear trend mode(3.5%).Critical factors are analyzed and regression equations are established for all the principal components,and then an annual hindcast model is established by synthesizing the results of the three modes.This model provides an annual spatial prediction of the sea ice in the Bohai Sea for the first time,and meets the demand of operational sea ice forecasting. | JIAO Yan HUANG Fei LIU Qingrong LI Ge LI Yaru YU Qingxi ZHAO Yiding | 2020 | Journal of Ocean University of China2020，19，2： | 2 |
| 19 | Fast Distance Protection Scheme for Wind Farm Transmission Lines Considering R-L and Bergeron Models显示文摘The distributed capacitance of the line becomes larger as the scale of wind farms,the transmission voltage level,and the transmission distance increase.Hence,the error of the traditional time-domain distance protection scheme based on the R-L model,which ignores the distributed capacitance of the line,becomes unacceptable.Therefore,the error of the time-domain fault location method based on the R-L model,especially the maximum error range,is theoretically analyzed in this paper.On this basis,a novel fault location method based on the RL and Bergeron models is proposed.Then,a fast time-domain distance protection scheme is designed.In the proposed scheme,the error in the fitting calculation is used to construct a weight matrix,and an algorithm for solving the time-domain differential equations is designed to improve the calculation speed and stability.Compared with the traditional frequency-domain distance protection scheme,the proposed scheme is independent of the power supply characteristics;thus,it is suitable for wind farm transmission lines.In addition,compared with the traditional method based on the R-L model,the proposed scheme effectively avoids the negative influence of the distributed capacitance of the line,which significantly improves the operating speed.Different types of faults are simulated by PSCAD/EMTDC to verify the effectiveness and superiority of the proposed scheme. | Zepeng Hu Bin Li Yuping Zheng Tonghua Wu Jiawei He Bin Yao Yaru Sheng Wei Dai Xindong Li | 2023 | Journal of Modern Power Systems and Clean Energy2023，11，3： | 2 |
| 20 | On-line quantum state estimation using continuous weak measurement and compressed sensing显示文摘Dear editor,Quantum state estimation(QSE)is the most important work in quantum information processing and quantum feedback control,which is usually formulated by means of strong measurements of an informationally complete set of measurement operators and corresponding observables.However,strong measurements collapse the original quantum state,the ensemble must be reprepared,and the measurement apparatus has to be reconfigured at each step.Weak measurements(WM)[1]offer an alternative in acquiring quantum measurements and estimating quantum states.In the measuring process,by using continuous weak measurements(CWM)it is possible to gain the target state information without disturbing it substantially,and the value recovered in CWM can be obtained by computing the ensemble averaging.Compressed sensing(CS)[2]has been brought into the quantum domain in the context of reducing the number of measurements required for QSE[3,4].However,whether a unified efficient scheme for on-line quantum state estimation using CWM and partial measurements is feasible,remains unknown. | Shuang CONG Yaru TANG Sajede HARRAZ Kezhi LI Jingbei YANG | 2021 | Science China(Information Sciences)2021，64，8： | 2 |
