A bio-robot system refers to an animal equipped with Brain-Computer Interface （BCI）, through which the outer stimulation is delivered directly into the animal＇s brain to control its behaviors. The development ofbio-robots suffers from the dependency on real-time guidance by human operators. Because of its inherent difficulties, there is no feasible method for automatic con- trolling of bio-robots yet. In this paper, we propose a new method to realize the automatic navigation for bio-robots. A General Regression Neural Network （GRNN） is adopted to analyze and model the controlling procedure of human operations. Com- paring to the traditional approaches with explicit controlling rules, our algorithm learns the controlling process and imitates the decision-making of human-beings to steer the rat-robot automatically. In real-time navigation experiments, our method suc- cessfully controls bio-robots to follow given paths automatically and precisely. This work would be significant for future ap- plications of bio-robots and provide a new way to realize hybrid intelligent systems with artificial intelligence and natural biological intelligence combined together.

A sequence of alkali metal cation-exchanged Co metal-organic frameworks(Co-MOFs),therein after denoted as M@Co-MOF,M=Na+,K+,Rb\and Cs+,was prepared and used as the precursors to obtain the corresponding alkali doped cobalt oxide(defined as M/C03O4,M=Na+,K\Rb\and Cs+)through calcination under air *** cobalt oxide modified by unifbnn alkali metals exhibited a significant promotion of catalytic activity for CO *** activity of M/Co3O4 decreased in the order of Cs+>Na+>K+>Rb+.Experimental and theoretical results revealed that the anionic skeleton of Co-MOF could tacilely adsorb alkali metal cations and play a cnicial role in the formation of higlily unilonn alkali doped cobalt *** further characterizations,such as temperature-programmed reduction of H2(H2-TPR),oxygen temperature-programmed desorption(O2-TPD),X-ray photoelectron spectroscopy(XPS),and in situ diffuse reflectance infrared Fourier transiorm(DRIFT)spectra demonstrated that the enlianced catalytic activity is originated from the interfacial electron transfer as well as weakened the Co-O bond strength,which promoted oxygen desorption from CO3O4 and fomiation of cobalt species with the lower valence *** Cs/Co3O4 catalyst was maintained for 60 h without deactivation and still showed a high activity in the presence of water.

网络空间信息可视化对揭示网络空域规律、促进网络空间认知具有重要意义。将网络空间节点与拓扑关系直接可视化的视图中存在大量的点重合和线交叉,目前已有的网络节点布局算法、集束边技术、骨干网提取和网络路由拓扑多尺度表达等方法能够优化视图效果,但在网络的微观结构上,对保持网络空间点群要素的特征信息关注不够。通过分析并量化网络空间点群要素的各类特征信息,提出了一种基于层次聚类的要素聚合方法和一种基于节点重要性度量的要素选取方法,以自动综合的方式对网络空间点群要素进行综合。实验结果表明,该方法能够保持网络空间点群要素的空间特征,为定量表达网络空间特征、加速生成视觉效果良好的网络空间地图提供基础数据综合方法。
