| 1 | Finite-time adaptive consensus of a class of multi-agent systems显示文摘Multi-agent systems(MASs) are ubiquitous in natural and artificial systems. This paper aims to establish the finite-time adaptive consensus criterion for a class of MASs with nonlinear dynamics. Traditionally, the finite-time consensus criterion is often established based on the prior information on Lipschitz constants and the eigenvalues of Laplacian matrix. However, it is difficult to acquire the above prior information for most real-world engineering systems. To overcome the above difficulty, this paper develops the finite-time consensus criteria for a class of MASs with nonlinear dynamics via adaptive technique. In detail, we design the finite-time distributed node-based and edge-based adaptive consensus protocols for a class of MASs with fixed and switching topologies. Numerical simulations are also given to validate the proposed finite-time adaptive consensus criterion. | LIU KeXin WU LuLu Lü JinHu ZHU HengHui | 2016 | Science China(Technological Sciences)2016，59，1： | 16 |
| 2 | Mixing and Vaporization Process of Injecting Water in Hydrogenation Unit显示文摘Injecting water into the main pipeline is a common method to prevent the ammonium salt corrosion in hydrogenation units.The use of spray nozzle can enhance the effects of washing ammonium salt and reduce the risk of ammonium salt corrosion.The droplet atomization and evaporation model were used to investigate the mixing process of injecting water and gas-oil mixture in a high-pressure environment.The effects of some key parameters including fluid velocity,temperature,and droplet volume fraction on the mixing and vaporization process were analyzed.Numerical simulation results show that with the increase of injecting water flow rate,the fluid velocity increases and the temperature decreases continuously.When the mass flow rate of injecting water is 1.5 t/h,the droplet has the maximum evaporation efficiency and the volume fraction reaches a minimum value.Besides,with the increase of atomization angle and droplet size,the mean velocity and the temperature of fluid decrease continuously.The increase of atomization angle or the decrease of droplet size will accelerate the evaporation process of droplets and reduce the droplet volume fraction,which indicates that the droplet slip velocity and the contact area are the key factors affecting the droplet evaporation rate. | Liu Xiaofei Yu Chenyang Zhu Haiyan Xu Henghui Jin Haozhe Wang Chao | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，4： | 1 |
| 3 | Partial recovery of disturbed V-J pairing profiles of T-cell receptor in people living with HIV receiving long-term antiretroviral therapy显示文摘Chronic human immunodeficiency virus(HIV) infection not only causes a gradual loss of CD4~+T cells but also leads to a disturbance of the T cell receptor(TCR) repertoire. In people living with HIV(PLWH), monitoring TCR repertoire is challenged by the inconsistency of complementarity determining region 3(CDR3) and limited cell numbers in clinical samples. Thus, a quantitative method is necessary for monitoring the TCR repertoire in PLWH.We characterized the TCR V-J pairing profile of na?ve and memory CD4~+T cells in healthy donors, HIV-infected antiretroviral therapy(ART)-na?ve patients and long-term(over5 years) ART-experienced patients by performing TCR sequencing. We developed a V-J index with 18 parameters which were subdivided into five categories(expression coverage, cumulative percentage of the top tenth percentile, diversity, intra-individual similarity and inter-individual similarity). In ART-na?ve patients, 14 of the 18 parameters were significantly altered.Long-term ART recovered ten parameters. The four unrecovered parameters were related to inter-individual similarity.Therefore, these findings indicate that long-term ART could only partially recover TCR V-J pairs and introduce newly impacted V-J pairs. Moreover, these results provide new insights into the V-J pairing of the TCR and into the disturbance of TCR repertoire in HIV infection. | Guoli Li Jiarui Li Henghui Zhang Yu Zhang Di Liu Yu Hao Junyan Han Juan Du Liuluan Zhu Yongqin Zeng Bei Li Rui Li Chuan Song Fujie Zhang Chen Chen Hongxin Zhao Hui Zeng | 2021 | Science China(Life Sciences)2021，64，1： | 0 |
