| 1 | Energy-Efficient Multi-UAV Coverage Deployment in UAV Networks:A Game-Theoretic Framework显示文摘UAV cooperative control has been applied in many complex UAV communication networks. It remains challenging to develop UAV cooperative coverage and UAV energy-efficient communication technology. In this paper, we investigate current works about UAV coverage problem and propose a multi-UAV coverage model based on energy-efficient communication. The proposed model is decomposed into two steps: coverage maximization and power control, both are proved to be exact potential games(EPG) and have Nash equilibrium(NE) points. Then the multi-UAV energy-efficient coverage deployment algorithm based on spatial adaptive play(MUECD-SAP) is adopted to perform coverage maximization and power control, which guarantees optimal energy-efficient coverage deployment. Finally, simulation results show the effectiveness of our proposed approach, and confirm the reliability of proposed model. | Lang Ruan Jinlong Wang Jin Chen Yitao Xu Yang Yang Han Jiang Yuli Zhang Yuhua Xu | 2018 | China Communications2018，15，10： | 24 |

| 4 | Variation of iron species in sliding mud显示文摘Results of Mossbauer spectroscopy and ICP-AES measurement revealed a special distribution pattern of iron species in four crossing profiles of the Tertiary Formation Type of Landslides in Japan. In comparison with host rocks, the sliding mud in the landslide slip zone contains the higher ferrous iron content and/or trace pyrite, which indicates that the forming environment was relatively reducing. The total iron content also increased with an increase in ferric iron and pyrite, in contrast, decreased with an increase in ferrous iron content. The deep-gray and black mud layers formed and accumulated in various volumes within landslide slip zones are treated as the basic criteria for the slipping activity, because the soft mud saturated with groundwater is easy to create a plastic deformation. | Guodong Zheng Sheng Xu Yuhua Lang Zifang Meng | 2002 | Chinese Science Bulletin2002，47，23： | 1 |
| 5 | A novel protein complex that regulates active DNA demethylation in Arabidopsis显示文摘Active DNA demethylation is critical for altering DNA methylation patterns and regulating gene expression.The 5-methylcytosine DNA glycosylase/lyase ROS1 initiates a base-excision repair pathway for active DNA demethylation and is required for the prevention of DNA hypermethylation at 1000 s of genomic regions in Arabidopsis.How ROS1 is regulated and targeted to specific genomic regions is not well understood.Here,we report the discovery of an Arabidopsis protein complex that contains ROS1,regulates ROS1 gene expression,and likely targets the ROS1 protein to specific genomic regions.ROS1 physically interacts with a WD40 domain protein(RWD40),which in turn interacts with a methyl-DNA binding protein(RMB1)as well as with a zinc finger and homeobox domain protein(RHD1).RMB1 binds to DNA that is methylated in any sequence context,and this binding is necessary for its function in vivo.Loss-of-function mutations in RWD40,RMB1,or RHD1 cause DNA hypermethylation at several tested genomic regions independently of the known ROS1 regulator IDM1.Because the hypermethylated genomic regions include the DNA methylation monitoring sequence in the ROS1 promoter,plants mutated in RWD40,RMB1,or RHD1 show increased ROS1 expression.Importantly,ROS1 binding to the ROS1 promoter requires RWD40,RMB1,and RHD1,suggesting that this complex dictates ROS1 targeting to this locus.Our results demonstrate that ROS1 forms a protein complex with RWD40,RMB1,and RHD1,and that this novel complex regulates active DNA demethylation at several endogenous loci in Arabidopsis. | Pan Liu Wen-Feng Nie Xiansong Xiong Yuhua Wang Yuwei Jiang Pei Huang Xueqiang Lin Guochen Qin Huan Huang Qingfeng Niu Jiamu Du Zhaobo Lang Rosa Lozano-Duran Jian-Kang Zhu | 2021 | Journal of Integrative Plant Biology2021，63，4： | 0 |
