| 1 | Overview on Submodule Topologies,Modeling,Modulation,Control Schemes,Fault Diagnosis,and Tolerant Control Strategies of Modular Multilevel Converters显示文摘In the present scenario,modular multilevel converters(MMCs)are considered to be one of the most promising and effective topologies in the family of high-power converters because of their modular design and good scalability;MMCs are extensively used in high-voltage and high-power applications.Based on their unique advantages,MMCs have attracted increasing attention from academic circles over the past years.Several studies have focused on different aspects of MMCs,including submodule topologies,modeling schemes,modulation strategies,control schemes for voltage balancing and circulating currents,fault diagnoses,and fault-tolerant control strategies.To summarize the current research status of MMCs,all the aforementioned research issues with representative research approaches,results and characteristics are systematically overviewed.In the final section,the current research status of MMCs and their future trends are emphasized. | Fujin Deng Yongqing Lu Chengkai Liu Qian Heng Qiang Yu Jifeng Zhao | 2020 | Chinese Journal of Electrical Engineering2020，6，1： | 15 |
| 2 | A brief review of forensically important flesh flies (Diptera: Sarcophagidae)显示文摘Forensic entomology could provide valuable data for the minimum postmortem interval (PMImin) estimation and other relevant information,such as causes and circumstances of death.Some representatives of flesh flies are one of the dominant necrophagous insects during early stages of decomposition,demonstrating unique biological characteristics compared with other necrophagous flies.Moreover,they lead to global health concerns as carriers of various pathogenic micro-organisms,and dominantly result in the traumatic myiasis.Thus,sarcophagid flies are considered important in decomposition processes for PMImin estimation.However,the utility of sarcophagid flies has been seriously hampered by limited ecological,biological and taxonomic knowledge of them.The aim of this paper is to provide a brief review on the species,distribution and biological habit of forensically important sarcophagid flies.In addition,the relation between traumatic myiasis and flesh flies,molecular identification methods and developmental pattern of flesh flies are summarized. | Lipin Ren Yanjie Shang Wei Chen Fanming Meng Jifeng Cai Guanghui Zhu Lushi Chen Yong Wang Jianqiang Deng Yadong Guo | 2018 | Forensic Sciences Research2018，3，1： | 3 |
| 3 | Current management of chemotherapy-induced neutropenia in adults:key points and new challenges显示文摘Chemotherapy-induced neutropenia(CIN)is a potentially fatal and common complication in myelosuppressive chemotherapy.The timing and grade of CIN may play prognostic and predictive roles in cancer therapy.CIN is associated with older age,poor functional and nutritional status,the presence of significant comorbidities,the type of cancer,previous chemotherapy cycles,the stage of the disease,specific chemotherapy regimens,and combined therapies.There are many key points and new challenges in the management of CIN in adults including:(1)Genetic risk factors to evaluate the patient’s risk for CIN remain unclear.However,these risk factors urgently need to be identified.(2)Febrile neutropenia(FN)remains one of the most common reasons for oncological emergency.No consensus nomogram for FN risk assessment has been established.(3)Different assessment tools[e.g.,Multinational Association for Supportive Care in Cancer(MASCC),the Clinical Index of Stable Febrile Neutropenia(CISNE)score model,and other tools]have been suggested to help stratify the risk of complications in patients with FN.However,current tools have limitations.The CISNE score model is useful to support decision-making,especially for patients with stable FN.(4)There are still some challenges,including the benefits of granulocyte colony stimulating factor treatment and the optimal antibiotic regimen in emergency management of FN.In view of the current reports,our group discusses the key points,new challenges,and management of CIN. | Committee of Neoplastic Supportive-Care(CONS),China Anti-Cancer Association Committee of Clinical Chemotherapy,China Anti-Cancer Association Yi Ba Yuankai Shi Wenqi Jiang Jifeng Feng Ying Cheng Li Xiao Qingyuan Zhang Wensheng Qiu Binghe Xu Ruihua Xu Bo Shen Zhiguo Luo Xiaodong Xie Jianhua Chang Mengzhao Wang Yufu Li Yuerong Shuang Zuoxing Niu Bo Liu Jun Zhang Li Zhang Herui Yao Conghua Xie Huiqiang Huang Wangjun Liao Gongyan Chen Xiaotian Zhang Hanxiang An Yanhong Deng Ping Gong Jianping Xiong Qinghua Yao Xin An Cheng Chen Yanxia Shi Jialei Wang Xiaohua Wang Zhiqiang Wang Puyuan Xing Sheng Yang Chenfei Zhou | 2020 | Cancer Biology & Medicine2020，17，4： | 2 |
| 4 | Harmonic Circulating Current Injection Based Power Loss Optimization Control of Bottom Switch/Diodes for Modular Multilevel Converters显示文摘Power loss management is one of the most significant challenges for reliability improvement of modular multilevel converters(MMCs).In the MMC,the bottom switch/diode in each submodule(SM)normally takes the maximum power loss.In this paper,a power loss optimization control(PLOC)for MMCs is proposed,where the maximum power losses in the bottom switch/diode of each SM can be effectively reduced through injecting optimum second-order harmonic current into the circulating current of MMCs,and accordingly the reliability of MMCs can be improved by the proposed PLOC.Simulation results with PSCAD software and experimental results with a 1 kW MMC platform are provided to confirm the validity of the proposed PLOC for MMCs. | Jifeng Zhao Fujin Deng Chengkai Liu Qiang Yu Qingsong Wang Jianzhong Zhang | 2021 | CSEE Journal of Power and Energy Systems2021，7，6： | 1 |
| 5 | Effects of an ectomycorrhizal fungus on the growth and physiology of Pinus sylvestris var. mongolica seedlings subjected to saline-alkali stress显示文摘This research investigates the mechanism of increased salinity tolerance of ectomycorrhizal fungiinoculated P. sylvestris var. mongolica to provide a theoretical basis for the application of the fungus in saline soils.Growth effects due to inoculation of seedlings with Suillus luteus(a symbiotic ectomycorrhizal fungus), were determined in four kinds of saline–alkali soils. Growth and physiological indicators, including photosynthetic characteristics, plant height, biomass, photosynthetic pigments,catalase(CAT) and superoxide dismutase(SOD) enzyme levels, and malondialdehyde(MDA), an organic marker for oxidative stress, and soluble protein levels were determined. Mycorrhizal colonization rate decreased with increasing saline–alkalinity and growth of inoculated seedlings was significantly enhanced. Biomass and chlorophyll contents also increased significantly. SOD and CAT activities were higher than in non-inoculated seedlings. However, MDA content decreased in inoculatedseedlings. Soluble protein content did not increase significantly. Inoculation with a symbiotic ectomycorrhizal fungus could enhance the saline–alkali tolerance of P. sylvestris var. mongolica. Growth and physiological performance of inoculated seedlings were significantly better than that of uninoculated seedlings. The results indicate that inoculated P. sylvestris var. mongolica seedlings may be useful in the improvement of saline–alkali lands. | Dachuan Yin Saiyaremu Halifu Ruiqing Song Jinyu Qi Xun Deng Jifeng Deng | 2020 | Journal of Forestry Research2020，31，3： | 1 |

| 7 | Overview of the LAMOST survey in the first decade显示文摘The Large Sky Area Multi-Object Fiber Spectroscopic Telescope(LAMOST),also known as the Guoshoujing Telescope,is a major national scientific facility for astronomical research located in Xinglong,China.Beginning with a pilot survey in 2011,LAMOST has been surveying the night sky for more than 10 years.The LAMOST survey covers various objects in the Universe,from normal stars to peculiar ones. | Hongliang Yan Haining Li Song Wang Weikai Zong Haibo Yuan Maosheng Xiang Yang Huang Jiwei Xie Subo Dong Hailong Yuan Shaolan Bi Yaoquan Chu Xiangqun Cui Licai Deng Jianning Fu Zhanwen Han Jinliang Hou Guoping Li Chao Liu Jifeng Liu Xiaowei Liu Ali Luo Jianrong Shi Xuebing Wu Haotong Zhang Gang Zhao Yongheng Zhao | 2022 | The Innovation2022，3，2： | 0 |
| 8 | Intrauterine fetal death in triplet gestation caused by feto-fetal transfusion syndrome–a case report显示文摘Feto-fetal transfusion syndrome(FFTS)severely affects monochorionic(MC)multiple pregnancies and affects 1 in 1600 pregnancies overall.The number of increasing disputed obstetrics cases in China is related to unavailability of prompt diagnosis of FFTS.We present here a woman with a MC triplet pregnancy with intrauterine fetal death at 33 weeks of gestation due to FFTS.Subsequent pathological anatomy showed that the MC placenta contained vascular anastomoses,including arterio-arterial anastomosis and arterio-venous anastomosis.These anastomoses led to unidirectional blood flow with the absence of adequate compensatory counter-transfusion and bi-directional flow.When encountering such challenging conditions,medical practitioners should discreetly compare the fetuses’characteristics with features of placental blood vessels and consult morphological and pathological findings.Furthermore,they should perform ultrasound examinations,particularly focussing on fetal size differences and the maximum vertical pocket in the diagnosis of FFTS,especially in MC multiple pregnancies with abdominal symptoms. | Lingling Long Jie Yan Qiyan Li Ziqi Zhou Haixiao Deng Chudong Wang Ying Zou Jifeng Cai | 2017 | Forensic Sciences Research2017，2，4： | 0 |
