1Three-dimensional cooperative guidance laws against stationary and maneuvering targets显示文摘This paper presents the cooperative strategies for salvo attack of multiple missiles based on the classical proportional navigation(PN) algorithm.The three-dimensional(3-D) guidance laws are developed in a quite simple formulation that consists of a PN component for target capture and a coordination component for simultaneous arrival.The centralized algorithms come into effect when the global information of time-to-go estimation is obtained, whereas the decentralized algorithms have better performance when each missile can only collect information from neighbors.Numerical simulations demonstrate that the proposed coordination algorithms are feasible to perform the cooperative engagement of multiple missiles against both stationary and maneuvering targets.The effectiveness of the 3-D guidance laws is also discussed.Zhao Jiang Zhou Rui Dong Zhuoning 2015Chinese Journal of Aeronautics2015,28,4:28
2Kinetics and mechanisms of mitotic inheritance of DNA methylation and their roles in aging-associated methylome deterioration显示文摘Mitotic inheritance of the DNA methylome is a challenging task for the maintenance of cell identity.Whether DNA methylation pattern in different genomic contexts can all be faithfully maintained is an open question.A replication-coupled DNA methylation maintenance model was proposed decades ago,but some observations suggest that a replication-uncoupled maintenance mechanism exists.However,the capacity and the underlying molecular events of replication-uncoupled maintenance are unclear.By measuring maintenance kinetics at the single-molecule level and assessing mutant cells with perturbation of various mechanisms,we found that the kinetics of replication-coupled maintenance are governed by the UHRF1–Ligase 1 and PCNA–DNMT1 interactions,whereas nucleosome occupancy and the interaction between UHRF1 and methylated H3K9 specifically regulate replication-uncoupled maintenance.Surprisingly,replication-uncoupled maintenance is sufficiently robust to largely restore the methylome when replication-coupled maintenance is severely impaired.However,solo-WCGW sites and other CpG sites displaying aging-and cancer-associated hypomethylation exhibit low maintenance efficiency,suggesting that although quite robust,mitotic inheritance of methylation is imperfect and that this imperfection may contribute to selective hypomethylation during aging and tumorigenesis.Xuan Ming Zhuqiang Zhang Zhuoning Zou Cong Lv Qiang Dong Qixiang He Yangyang Yi Yingfeng Li Hailin Wang Bing Zhu 2020Cell Research2020,30,11:4
3Author Correction: Kinetics and mechanisms of mitotic inheritance of DNA methylation and their roles in aging-associated methylome deterioration显示文摘We apologize for the mistake of the fund information in the acknowledgements.The correct information is as follows.This correction does not affect the conclusion of the work.Xuan Ming Zhuqiang Zhang Zhuoning Zou Cong Lv Qiang Dong Qixiang He Yangyang Yi Yingfeng Li Hailin Wang Bing Zhu 2021Cell Research2021,31,3:2
