| 1 | Effects of information feedback on an asymmetrical two-route scenario显示文摘In traffic system, a reasonable information feedback can improve road capacity. In this paper, we investigate an asymmetrical two-route scenario in which dynamic information can be generated and displayed on the board to guide drivers. Two improved feedbacks (i.e. improved mean velocity feedback and improved congestion coefficient feedback) are introduced. Simulations show that the average cost is dependent on the vehicle arrival rate and there exists a critical the dynamic vehicles ratio corresponding to the maximum flux. We find that improved con-gestion coefficient can better enhance the system capacity than that of improved mean velocity feedback. | SUN XiaoYan WANG BingHong YANG HanXin WANG QiaoMing JIANG Rui | 2009 | Chinese Science Bulletin2009，54，18： | 4 |
| 2 | Universal role of migration in the evolution of cooperation显示文摘We study the role of unbiased migration in cooperation in the framework of the spatial evolutionary game on a variety of spatial structures, namely a regular lattice, continuous plane and complex networks. A striking finding is that migration plays a universal role in cooperation, regardless of the spatial structure. For a high degree of migration, cooperators cannot survive owing to their failure to form cooperator clusters that resist attacks by defectors. Meanwhile, for a low degree of migration, cooperation is considerably enhanced relative to that in the static spatial game, which is due to the strengthening of the boundaries of cooperator clusters by the occasional accumulation of cooperators along the boundaries. The cooperator cluster thus becomes more robust than that in the static game and defectors near the boundary can be assimilated by cooperators. The cooperator cluster thus expands, which facilitates cooperation. The general role of migration will be substantiated by sufficient simulations relating to heuristic explanations. | YANG HanXin WANG BingHong | 2011 | Chinese Science Bulletin2011，56，34： | 2 |

| 9 | A new dual-ion battery based on amorphous carbon显示文摘The Na-based dual-ion batteries(NDIBs),combining the advantages of Na-ion batteries and dual-ion batteries,are attracting more attention due to their merits of abundant source,low cost and high energy density.However,the main challenges faced by NDIBs are their low capacity and poor cycling.Herein,we report a new ion storage mechanism for high-performance NDIBs using amorphous carbon(AOMC)as cathode.Unlike the graphite carbon that can only accommodate the PF6-anion(typical DIB system),the AOMC herein can both accommodate Na+cation and PF6-anion due to its amorphous feature,which is conceptually new dual-ion system for achieving much higher capacity.Ex-situ X-ray photoelectron spectroscopy,X-ray diffraction and Raman studies reveal that the disordered carbon in the AOMC can be transformed to the partial graphitic stacking in short range,improving both capacity and cycling stability of NDIBs.As a consequence,the AOMC delivers a highly reversible storage capacity of 136 mAhg-1 for 800 cycles at a very high current density of 2.0 Ag-1,much higher than all the reported NDIBs.Such concept can be generalized to develop high-performance dual-ion full cell using sodium ion preintercalated materials as anode and AOMC as cathode. | Wei(Alex)Wang Hanxin Huang Bin Wang Chang Qian Peihao Li Jinhui Zhou Zibin Liang Chao Yang Shaojun Guo | 2019 | Science Bulletin2019，64，21： | 1 |

| 11 | Hybrid Two-Phase Task Allocation for Mobile Crowd Sensing显示文摘As a result of the popularity of mobile devices,Mobile Crowd Sensing (MCS) has attracted a lot of attention. Task allocation is a significant problem in MCS. Most previous studies mainly focused on stationary spatial tasks while neglecting the changes of tasks and workers. In this paper,the proposed hybrid two-phase task allocation algorithm considers heterogeneous tasks and diverse workers.For heterogeneous tasks,there are different start times and deadlines. In each round,the tasks are divided into urgent and non-urgent tasks. The diverse workers are classified into opportunistic and participatory workers.The former complete tasks on their way,so they only receive a fixed payment as employment compensation,while the latter commute a certain distance that a distance fee is paid to complete the tasks in each round as needed apart from basic employment compensation. The task allocation stage is divided into multiple rounds consisting of the opportunistic worker phase and the participatory worker phase. At the start of each round,the hiring of opportunistic workers is considered because they cost less to complete each task. The Poisson distribution is used to predict the location that the workers are going to visit,and greedily choose the ones with high utility. For participatory workers,the urgent tasks are clustered by employing hierarchical clustering after selecting the tasks from the uncompleted task set.After completing the above steps,the tasks are assigned to participatory workers by extending the Kuhn-Munkres (KM) algorithm.The rest of the uncompleted tasks are non-urgent tasks which are added to the task set for the next round.Experiments are conducted based on a real dataset,Brightkite,and three typical baseline methods are selected for comparison. Experimental results show that the proposed algorithm has better performance in terms of total cost as well as efficiency under the constraint that all tasks are completed. | LIU Jiahao JIN Hanxin QIANG Lei GAO Guoju DU Yang HUANG He | 2022 | 计算机工程2022，48，3： | 0 |
