| 1 | Pinning control of general complex dynamical networks with optimization显示文摘This paper addresses optimal pinning control of general complex dynamical networks. A pinning scheme with linear feedback is proposed to globally exponentially stabilize a network onto a homogeneous state. In particular, we answer an important and fundamental question about pinning control: how to select an optimal combination between the number of pinned nodes and the feedback control gain? Three illustrative examples are provided to show the effectiveness of the proposed technique. | ZHAO JunChan LU JunAn WU XiaoQun | 2010 | Science China(Information Sciences)2010，53，4： | 8 |

| 3 | Propofol-Induced Anesthesia Alters Corticocortical Functional Connectivity in the Human Brain:An EEG Source Space Analysis显示文摘Dear Editor,Anesthetic-induced unconsciousness is accompanied by decreased information exchange among relevant cortical functional modular areas that support normal cognitive function[1].Using the electroencephalogram(EEG)signal,evidence suggest that the feedback and feedforward connectivity among cortical regions may be asymmetrically affected during anesthetic-induced anesthesia[2]. | Xue Zhao Yubo Wang Yun Zhang Haidong Wang Junchan Ren Fei Yan Dawei Song Ruini Du Qiang Wang Liyu Huang | 2021 | Neuroscience Bulletin2021，37，4： | 1 |
| 4 | A randomized clinical efficacy trial of Hehui capsule against hyperlipidemia显示文摘Hehui capsule(Hhc)has been used as an assistant treatment for hyperlipidemia.According to the previous studies,miltiorrhiza and Chavica roxburghii may reduce the serum lipid level.This study aims at examining the efficiency of Hehui capsule with regards to treating hyperlipidemia in a randomized control,double-blind clinical trial.In the research,we assigned 104 eligible subjects to Hehui capsule group and placebo groups(52:52,respectively).Subjects used self-control and inter-group controls to compare serum total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL)and other changes before and after the test group and the test group and the control group.During the 45 days intervention,101 cases were actually included,among which 51 cases for test group,and other 50 cases for placebo group.The total effective rate of blood lipid reduction(90.20%)in the test group was significantly higher than that in the control group(26.00%)(P<0.01).Together,the result indicates that Hhc has a certain curative effect on dyslipidemia,with no obvious adverse reactions,which can be developed into a new drug for hyperlipidemia. | Ruiting Ma Yuanyuan Ma Junchan Qiao Lixia Chen Mingxing Hou | 2022 | Medicine in Novel Technology and Devices2022，，4： | 0 |
| 5 | Sinusoidal disturbance induced topology identification of Hindmarsh-Rose neural networks显示文摘Topology identification of complex networks is an important problem. Existing research shows that the synchronization of network nodes is an obstacle in the identification of network topology. Identification of the structure of the network presents an interesting challenge during the synchronization of complex networks.We developed a new method using the sinusoidal disturbance to identify the topology when the complex network achieves synchronization. Compared with the disturbance of all the nodes, the disturbance of the key nodes alone can achieve a very good effect. Finally, numerical simulation data are provided to validate our hypothesis. | Junchan ZHAO M.A.AZIZ-ALAOUI Cyrille BERTELLE Nathalie CORSON | 2016 | Science China(Information Sciences)2016，59，11： | 0 |
| 6 | Analysis on the Mutation and Time-Varying Characteristics of Coal Price System Evolution from the Perspective of Finance显示文摘Coal is essential to ensure China’s energy security.The sudden or gradual change of coal price reflects the degree of disequilibrium or expected disequilibrium of coal supply and demand,which will not be conducive to energy security.Therefore,it is important to analyze the change points of coal price and explore the reason of the price fluctuation.This paper analyses the coal price from January2008 to June 2019 as the perspective of the financial market.Firstly,the PPM-DBSCAN model is used to identify the mutation point of coal price fluctuation.Secondly,path analysis is used to extract the core driving factors that affect coal price.Thirdly,the authors construct a time-varying and time-lag effect analysis model for structural changes of coal price based on the TVP-VAR model.The results show that there are 11 mutation points of coal price fluctuation.Financial market factors,coal supply and demand and alternative factors are the reasons of coal price mutation.The authors find that the imbalance of coal supply and demand in traditional view cannot fully explain the fluctuation of coal price.The impact of the financial market and non-thermal power generation have more influence on the coal price. | CHAI Jian LEI Junchan SHI Huiting ZHANG Xuejun LANG Meiling | 2021 | Journal of Systems Science & Complexity2021，34，4： | 0 |
| 7 | Fixed-Time Synchronization of Complex Networks via Intermittent Control Without Sign Function显示文摘This paper investigates the fixed-time synchronization problem of complex networks.A novel switching controller is proposed to solve the problem.The designed controller in this paper only needs intermittently to pin a few of nodes,which could reduce the control time and save the system’s energy.Moreover,compared with the existing control methods for the fixed-time synchronization,the novel controller does not use the sign function,which could avoid the chattering behaviors.By constructing a Lyapunov function and designing a comparison system,some sufficient conditions are obtained to achieve the fixed-time synchronization.Finally,the numerical simulations could verify the effectiveness and feasibility of the proposed control approaches. | GAO Jie ZHAO Junchan | 2022 | Journal of Systems Science & Complexity2022，35，5： | 0 |
