认知地图不仅可以映射物理空间,还可以支持认知空间映射,形成包括感知空间、情景记忆空间、概念空间和社会空间等在内的跨不同信息领域的地图式表征。认知空间映射的神经机制包括海马体对潜在结构的抽象和概括、支持分布式位置地图的生成、将信息与背景结构捆绑,以及海马体与其它脑区的协同。未来研究应关注预测性的认知空间地图、海马体对不同精度和层级信息的表征、认知空间映射微观和介观层面的研究空缺以及物理空间和认知空间映射的共同机制和特异性机制等问题。

近年来,极端天气气候事件频发,城市洪涝灾害对社会安全构成严重威胁。为有效处置紧急灾害事件,该文从协同视角出发,以“7·31北京暴雨”作为研究案例,采用结构洞与社会网络分析方法,将参与救援的相关职能部门作为研究对象,构建部门间2-模灾害应急协同网络。通过分析得出:市级应急组织的凝聚力较强,获取资源信息途径较多,拥有更多运用结构洞的能力。相较而言,县-区级应急组织的整体协同能力相对薄弱,其节点关系的衔接程度较松散。基于此提出:强化区县级政府的应急统筹协调能力、深化边缘组织与核心部门之间的合作、提升市-区资源信息的传递效率。为减轻灾害损失、厘清应急网络中的组织协同关系以及完善协同联动机制提供参考。

针对现有孪生网络跟踪算法仅使用主干网络最后一层的特征进行相似度匹配,以及缺少有效模板更新策略的问题,提出基于多尺度特征融合和自适应模板更新的孪生网络跟踪算法。首先,结合深度过参数化卷积设计非填充单元,提取更深层的前景特征和语义背景;然后,设计新的全局-局部特征融合模块,充分聚合浅、中层特征的全局和局部信息,捕获丰富的浅层外观特征和中层过渡特征;最后,采用自适应模板更新机制在线更新模板。为验证算法的有效性,在公开数据集上对所提算法进行详尽评估,实验结果显示,所提算法在OTB2015和VOT2018数据集上的精确度分别达到0.878和0.588,GOT10K数据集上平均重叠率达到0.526,优于其他主流算法。

The impact of information dissemination on epidemic control is essentially subject to individual behaviors. Vaccination is one of the most effective strategies against the epidemic spread, whose correlation with the information dissemination should be better understood. To this end, we propose an evolutionary vaccination game model in multiplex networks by integrating an information-epidemic spreading process into the vaccination dynamics, and explore how information dissemination influences vaccination. The spreading process is described by a two-layer coupled susceptible-alert-infected-susceptible(SAIS) model, where the strength coefficient between two layers characterizes the tendency and intensity of information *** find that the impact of information dissemination on vaccination decision-making depends on not only the vaccination cost and network topology, but also the stage of the system evolution. For instance, in a two-layer BA scale-free network, information dissemination helps to improve vaccination density only at the early stage of the system evolution, as well as when the vaccination cost is smaller. A counter-intuitive conclusion that more information transmission cannot promote vaccination is obtained when the vaccination cost is larger. Moreover, we study the impact of the strength coefficient and individual sensitivity on the fraction of infected individuals and social cost, and unveil the role of information dissemination in controlling the epidemic.
