| 1 | Controllability of multi-agent systems based on agreement protocols显示文摘This paper investigates the controllability of multi-agent systems based on agreement protocols. First, for a group of single-integrator agents, the controllability is studied in a unified framework for both networks with leader-following structure and networks with undirected graph. Some new necessary/sufficient conditions for the controllability of networks of single-integrator agents are established. Second, we prove that, under the same topology and same prescribed leaders, a network of high-order dynamic agents is completely controllable if and only if so is a network of single-integrator agents. Third, how the selection of leaders and the coupling weights of graphs affect the controllability is analyzed. Finally, some numerical simulations are presented to demonstrate the effectiveness of the theoretical results. | WANG Long JIANG FangCui XIE GuangMing JI ZhiJian | 2009 | Science in China(Series F)2009，52，11： | 19 |
| 2 | Consensus of high-order dynamic multi-agent systems with switching topology and time-varying delays显示文摘This paper studies the consensus problems for a group of agents with switching topology and time-varying communication delays,where the dynamics of agents is modeled as a high-order integrator.A linear distributed consensus protocol is proposed,which only depends on the agent's own information and its neighbors'partial information.By introducing a decomposition of the state vector and performing a state space transformation,the closed-loop dynamics of the multi-agent system is converted into two decoupled subsystems.Based on the decoupled subsystems,some sufficient conditions for the convergence to consensus are established,which provide the upper bounds on the admissible communication delays.Also,the explicit expression of the consensus state is derived.Moreover,the results on the consensus seeking of the group of high-order agents have been extended to a network of agents with dynamics modeled as a completely controllable linear time-invariant system.It is proved that the convergence to consensus of this network is equivalent to that of the group of high-order agents.Finally,some numerical examples are given to demonstrate the effectiveness of the main results. | Fangcui JIANG,Long WANG,Guangming XIE(Institute of Intelligent Engineering,Center for Systems and Control,College of Engineering,and Key Laboratory of Machine Perception(Ministry of Education),Peking University,Beijing 100871,China) | 2010 | 控制理论与应用(英文版)2010，8，1： | 11 |

| 5 | Raman lasing and Fano lineshapes in a packaged fiber-coupled whispering-gallery-mode microresonator显示文摘We report Raman lasing and the optical analog of electromagnetically-induced-transparency(EIT) in a whispering-gallery-mode(WGM) microtoroid resonator embedded in a low refractive index polymer matrix together with a tapered fiber coupler. The microtoroid resonator supports both single mode and multimode Raman lasing with low power thresholds. Observations of Fano and EIT-like phenomena in a packaged microresonator will enable high resolution sensors and can be used in networks where slow-light effect is needed. These results will open up new possibilities for portable, robust, and stable WGM microlasers and resonator-based sensors for applications in various environments. | Guangming Zhao Sahin Kaya Ozdemir Tao Wang Linhua Xu Eshan King Gui-Lu Long Lan Yang | 2017 | Science Bulletin2017，62，12： | 6 |
| 6 | Shellac-coated iron oxide nanoparticles for removal of cadmium(Ⅱ) ions from aqueous solution显示文摘This study describes a new effective adsorbent for cadmium removal from aqueous solution synthesized by coating a shellac layer, a natural biodegradable and renewable resin with abundant hydroxyl and carboxylic groups, on the surface of iron oxide magnetic nanoparticles. Transmission Electron Microscopy (TEM) imaging showed shellac-coated magnetic nanoparticle (SCMN) adsorbents had a core-shell structure with a core of 20 nm and shell of 5 nm. Fourier Transform Infrared Spectroscopic analysis suggested the occurrence of reaction between carboxyl groups on the SCMN adsorbent surface and cadmium ions in aqueous solution. Kinetic data were well described by pseudo second-order model and adsorption isotherms were fitted with both Langmuir and Freundlich models with maximum adsorption capacity of 18.80 mg/g. SCMN adsorbents provided a favorable adsorption capacity under high salinity conditions, and cadmium could easily be desorbed using mild organic acid solutions at low concentration. | Jilai Gong Long Chen Guangming Zeng Fei Long Jiuhua Deng Qiuya Niu Xun He | 2012 | Journal of Environmental Sciences2012，24，7： | 5 |
| 7 | A switched system approach to stabilization of networked control systems显示文摘A switched system approach is proposed to model networked control systems (NCSs) with communication constraints. This enables us to apply the rich theory of switched systems to analyzing such NCSs. Sufficient conditions are presented on the stabilization of NCSs. Stabilizing state/output feedback controllers can be constructed by using the feasible solutions of some linear matrix inequalities (LMIs). The merit of our proposed approach is that the behavior of the NCSs can be studied by considering switched system without augmenting the system. A simulation example is worked out to illustrate the effectiveness of the proposed approach. | Mei YU Long WANG Guangming XIE | 2006 | 控制理论与应用(英文版)2006，4，1： | 4 |
| 8 | Molecular analysis of cell-free DNA identifies distinct molecular features in patients with chemosensitive and chemorefractory small cell lung cancer显示文摘Dear Editor,Lung cancer is the predominant cause of cancer-related death worldwide[1].Non-small cell lung cancer accounts for 80%-85%and small cell lung cancer(SCLC)accounts for 15%-20%of all lung cancer cases[2].Patients with SCLC,a highly aggressive and poorly differentiated malignancy,have an alarming average 5-year overall sur-vival rate of less than 10%[3].Most patients with SCLC already show clinically detectable metastases at diag-nosis and have extremely poor prognoses,even when treated with multimodality therapy[4].Before the addi-tion of atezolizumab to chemotherapy became the first-line treatment of extensive-stage SCLC,chemotherapy is the primary treatment of SCLC[5]. | Jie Zhang Chen Tian Fang Lv Jianfei Wang Wenbo Han Jun Nie Ling Dai Weiheng Hu Xiaoling Chen Xiangjuan Ma Guangming Tian Di Wu Sen Han Yang Wang Jieran Long Ziran Zhang Jian Fang Henghui Zhang | 2019 | Cancer Communications2019，39，1： | 2 |

| 13 | Fabrication of Bi-Bi3O4Cl plasmon photocatalysts for removal of aqueous emerging contaminants under visible light显示文摘Photocatalytic oxidation of emerging contaminants(ECs) in water has recently gained extensive attentions. In this study, bismuth oxychloride-based plasmon photocatalysts(BiBiOCl) exhibiting high performance were successfully developed by reducing Bion the surface of BiOCl. Consequently, the photocatalysts were used to remove ECs from water.The effects of developmental process and Bi metal plasmon resonance on the photoelectric performances of Bi-BiOCl were investigated through a series of characterizations. The UV-vis diffuse reflection and photoluminescence spectra revealed that the light absorption range of the photocatalyst gradually increased and the electron recombination rate gradually decreased with the introduction of Bi metals. The optimal removal rates of ciprofloxacin and tetrabromobisphenol A by Bi-BiOCl were 93.8% and 96.4%;the respective reaction rate constants were 5.48 and 4.93 times higher than that of BiOCl. The mechanism study indicated that main reactants in the photocatalytic system were ·O-2radicals and photogenerated holes, and the existence of oxygen vacancies and Bi metals promoted electron transfer in photocatalyst. In conclusion, this research produces a novel, green, highly efficient, and stable visible light photocatalyst for the removal of ECs from water. | Zeqing Long Hui Song Guangming Zhang Jingsi Gao Jia Zhu | 2022 | Journal of Environmental Sciences2022，34，8： | 1 |

| 18 | Rb-Sr Dating of Pyrite and Quartz Fluid Inclusions and Origin of Ore-forming Materials of the Jinshan Gold Deposit, Northeast Jiangxi Province, South China显示文摘The Jinshan gold deposit is located in the Northeast Jiangxi province,South China,which related to the ductile shear zone.It contains two ore types,i.e.the alteration-type ore and the goldbearing quartz vein ore.Rb-Sr age dating is applied to both gold-bearing pyrite in the alteration-type ore and fluid inclusion in the gold-bearing quartz vein to make clear the time of the gold mineralization of the Jinshan deposit.Analytical results of this study yielded that the age of the alteration-type ore bodies is about 838±110Ma,with an initial87Sr/86Sr value of 0.7045±0.0020.However,the age of the gold-bearing quartz vein-type ore is about 379±49Ma,and the initial87Sr/86Sr is 0.7138±0.0011.Based on the age data from this work and many previous studies,the authors consider that the Jinshan gold deposit is a product of multi-staged mineralization,which may include the Jinninian,Caledonian,Hercynian,and Yanshanian Periods.Among them,the Jinninian Period and the Hercynian Period might be the two most important ore-forming periods for Jinshan deposit.The Jinninian Period is the main stage for the formation of alteration-type ore bodies,while the Hercynian Period is the major time for ore bodies of gold-bearing quartz vein type.The initial values of the87Sr/86Sr from this study,as well as the previous isotope and trace element studies,indicate that the ore-forming materials mainly derived from the metamorphic wall rocks,and the ore-forming fluids mainly originated from the deep metamorphic water. | MAO Guangzhou HUA Renmin LONG Guangming LU Huijuan | 2013 | Acta Geologica Sinica(English Edition)2013，87，6： | 1 |
