| 1 | Evidence combination method in time domain based on reliability and importance显示文摘In order to achieve the information fusion in the time domain based on the evidence theory, an evidence combination method in the time domain based on reliability and importance is proposed according to the idea of evidence discount. Firstly, the distortion of the time-domain evidence is judged based on single exponential smoothing. The real-time reliability of the evidence at the adjacent time is obtained by the real-time reliability assessment method of the evidence based on the credibility decay model.Then, the relative importance of the evidence at the adjacent time is obtained by comprehensively considering improved conflict degree and uncertainty. Finally, based on the criterion of evidence discount and the Dempster's rule of combination, the evidence combination is carried out to achieve the sequential combination of time-domain evidence. The numerical simulation and analysis show that this method has fully embodied the dynamic characteristics of time-domain evidence combination, and it has strong processing ability for conflict information and anti-disturbing ability.The proposed method has good applicability to information fusion in the time domain. | LUO Chengkun CHEN Yunxiang XIANG Huachun WANG Weijia WANG Zezhou | 2018 | Journal of Systems Engineering and Electronics2018，29，6： | 2 |
| 2 | Structural insights into the membrane microdomain organization by SPFH family proteins显示文摘The lateral segregation of membrane constituents into functional microdomains,conceptually known as lipid raft,is a universal organization principle for cellular membranes in both prokaryotes and eukaryotes.The widespread Stomatin,Prohibitin,Flotillin,and HflK/C(SPFH)family proteins are enriched in functional membrane microdomains at various subcellular locations,and therefore were hypothesized to play a scaffolding role in microdomain formation.In addition,many SPFH proteins are also implicated in highly specific processes occurring on the membrane.However,none of these functions is understood at the molecular level.Here we report the structure of a supramolecular complex that is isolated from bacterial membrane microdomains and contains two SPFH proteins(HflK and HflC)and a membrane-anchored AAA+protease FtsH.HflK and HflC form a circular 24-mer assembly,featuring a laterally segregated membrane microdomain(20 nm in diameter)bordered by transmembrane domains of HflK/C and a completely sealed periplasmic vault.Four FtsH hexamers are embedded inside this microdomain through interactions with the inner surface of the vault.These observations provide a mechanistic explanation for the role of HflK/C and their mitochondrial homologs prohibitins in regulating membrane-bound AAA+proteases,and suggest a general model for the organization and functionalization of membrane microdomains by SPFH proteins. | Chengying Ma Chengkun Wang Dingyi Luo Lu Yan Wenxian Yang Ningning Li Ning Gao | 2022 | Cell Research2022，32，2： | 0 |
| 3 | New approach for uncertain random multi-objective programming problems based on C_(ESD) criterion显示文摘To overcome the defects that the traditional ap-proach for multi-objective programming under uncertain ran-dom environment(URMOP)neglects the randomness and uncer-tainty of the problem and the volatility of the results,a new ap-proach is proposed based on expected value-standard devi-ation value criterion(C_(ESD) criterion).Firstly,the effective solution to the URMOP problem is defined;then,by applying sequence relationship between the uncertain random variables,the UR-MOP problem is transformed into a single-objective program-ming(SOP)under uncertain random environment(URSOP),which are transformed into a deterministic counterpart based on the C_(ESD) criterion.Then the validity of the new approach is proved that the optimal solution to the SOP problem is also effi-cient for the URMOP problem;finally,a numerical example and a case application are presented to show the effectiveness of the new approach. | SUN Yun WANG Ying MENG Xiangfei FU Chaoqi LUO Chengkun | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 0 |
