| 1 | Combined indirect and direct method for adaptive fuzzy output feedback control of nonlinear system显示文摘A novel control method for a general class of nonlinear systems using fuzzy logic systems (FLSs) is presertted. Indirect and direct methods are combined to design the adaptive fuzzy output feedback controller and a high-gain observer is used to estimate the derivatives of the system output. The closed-loop system is proven to be semiglobally uniformly ultimately bounded. In addition, it is shown that if the approximation accuracy of the fuzzy logic system is high enough and the observer gain is chosen sufficiently large, an arbitrarily small tracking error can be achieved. Simulation results verify the effectiveness of the newly designed scheme and the theoretical discussion. | Ding Quanxin Chen Haitong Jiang Changsheng Chen Zongji | 2007 | Journal of Systems Engineering and Electronics2007，18，1： | 2 |
| 2 | Comparison of the clinical features and therapeutics of COVID-19 in cardio-cerebrovascular disease(CCVD)and non-CCVD patients显示文摘Cardio-cerebrovascular disease(CCVD)is a major comorbidity of coronavirus disease 2019(COVID-19).However,the clinical characteristics and outcomes remain unclear.In this study,102 cases of COVID-19 from January 22,2020 to March 26,2020 in Xixi Hospital of Hangzhou were included.Twenty cases had pre-existing CCVD.Results showed that compared with non-CCVD patients,those with CCVD are more likely to develop severe disease(15%versus 1%),and the proportion of pneumonia severity index grade IV was significantly higher(25%versus 3.6%).Computed tomography images demonstrated that the proportion of multiple lobe lesion involvement was significantly higher in the CCVD group than in the non-CCVD group(90%versus 63.4%).Compared with non-CCVD group,the levels of C-reactive protein,fibrinogen,D-dimer,and serum amyloid-A were higher,whereas the total protein and arterial partial Pa02 were lower in the CCVD group.Although no statistical difference was observed in the outcomes between groups,CCVD patients received more intensive comprehensive treatment to improve COVID-19 symptoms compared with non-CCVD patients.Integrated Chinese and Western medicine treatments have certain advantages in controlling the severe conversion rate and mortality of COVID-19.In addition,given that COVID-19 patients are usually related to coagulation disorders and thrombosis risk,the application of Chinese medicine in promoting blood circulation and removing stasis should be strengthened. | Yu Wang Lan Li Yuanjiang Pan Yu He Zuhua Chen Yunhao Xun Yuhan Xu Yilei Guo Jiehong Yang Jianchun Guo Haitong Wan | 2021 | Frontiers of Medicine2021，15，4： | 1 |

| 4 | RNF219 interacts with CCR4-NOT in regulating stem cell differentiation显示文摘Regulation of RNA stability plays a crucial role in gene expression control.Deadenylation is the initial rate-limiting step for the majority of RNA decay events.Here,we show that RING finger protein 219(RNF219)interacts with the CCR4-NOT deadenylase complex.RNF219-CCR4-NOT exhibits deadenylation activity in vitro.RNA-seq analyses identify some of the 2-cell-specific genes and the neuronal genes significantly downregulated upon RNF219 knockdown,while upregulated after depletion of the CCR4-NOT subunit CNOTIO in mouse embryonic stem(ES)cells.RNF219 depletion leads to impaired neuronal lineage commitment during ES cell differentiation.Our study suggests that RNF219 is a novel interacting partner of CCR4-NOT and required for maintenance of ES cell pluripotency. | Hao Du Chen Chen Yan Wang Yang Yang Zhuanzhuan Che Xiaoxu Liu Siyan Meng Chenghao Guo Manman Xu Haitong Fang Fengchao Wang Chengqi Lin Zhuojuan Luo | 2020 | Journal of Molecular Cell Biology2020，12，11： | 0 |
