传统的应用于未登录词语义研究的语料库包含许多限制,例如更新慢、语言相关等。为了解决此问题,提出了基于知识图谱的中文未登录词语义研究方法。知识图谱是一种包含实体、概念及语义关系的语义网络。它具有丰富的实体,并且实体及其关系的添加极为方便,使得弥补传统语料库更新慢的缺憾成为可能。在充分熟悉知识图谱的结构、数据获取方法及相关数据处理方法后,进行基于知识图谱的未登录词语义研究的探索工作,最后以百度百科(目前最大的中文知识图谱)为语料资源,在同一语义分析模型下分别进行基于知识图谱与传统语料的实验,对实验结果进行分析并提出改进方法。

Information flow between the prefrontal and visual cortices is critical for visual behaviors such as visual search. To investigate its mechanisms, we simultaneously recorded spike and local field potential (LFP) signals in the frontal eye field (FEF) and area V4 while monkeys performed a free-gaze visual search task. During free-gaze search, spike-LFP coherence between FEF and V4 was enhanced in the theta rhythm (4–8 Hz) but suppressed in the alpha rhythm (8–13 Hz). Cross-frequency couplings during the Cue period before the search phase were related to monkey performance, with higher FEF theta-V4 gamma coupling and lower FEF alpha-V4 gamma coupling associated with faster search. Finally, feature-based attention during search enhanced spike-LFP coherence between FEF and V4 in the gamma and beta rhythms, whereas overt spatial attention reduced coherence at frequencies up to 30 Hz. These results suggest that oscillatory coupling may play an important role in mediating interactions between the prefrontal and visual cortices during visual search.

SELEX procedure is a methodology in which single stranded oligonucleotides are selected from a wide variety of sequences based on their interaction with a target molecule. Dendritic cells (DC) are professional antigen-presenting cells (APC) which make an essential function in atherogenesis. DC-SIGN is a novel DC-specific adhesion receptor that takes part in the interaction between DC and T cells or

Dear Editor,This letter studies the bipartite consensus tracking problem for heterogeneous multi-agent systems with actuator faults and a leader's unknown time-varying control input. To handle such a problem, the continuous fault-tolerant control protocol via observer design is developed. In addition, it is strictly proved that the multi-agent system driven by the designed controllers can still achieve bipartite consensus tracking after faults occur.
