Synthetic lethality describes an interaction whereby the co-occurrence of two mutations leads to cell death but one mutation alone does not,which can be exploited for cancer therapeutics.1 Due to lacking effective nonsurgical treatment and early clinical diagnosis markers,patients have high mortality and low overall survival rates in cholangiocarcinoma(CCA).

As background knowledge of geographic information retrieval (GIR),the gazetteers have their limitations. In this paper we propose to develop and implement a com-mon sense geographic knowledge base (CSGKB) instead of the gazetteers. We define that CSGKB is concerned with the representation of geographic knowledge in human brain and the simulation of geographic reasoning in daily life. Traditional geographic information system (GIS) is based on the model of map with its data based on geographic coordinates and its computation based on geometry. However,CSGKB,which is made up of geographic features and relationships and is based on qualitative spatio-temporal reasoning,can be viewed as the direct model of geographic world. This paper also discusses the characters of CSGKB and pre-sents its structure which is composed of knowledge base,inference engine,geo-graphic ontology and learner. The applications using CSGKB include geographic information retrieval (GIR),natural language processing (NLP),named entity rec-ognition (NER),Semantic Web,etc. At present,our work focuses on the design of geographic ontology and the implementation of the CSGKB knowledge base. In this paper we describe the CSGKB ontology structure,top ontology,geographic loca-tion ontology,spatial relationship ontology,and domain ontologies. Finally,we in-troduce the current state of implementation of CSGKB and give an outlook on our future researches.

功能梯度板中Griffith裂纹尖端应力场的三维解析研究

第37届中国控制会议

作者： lulu shen Shuli Jia Hao Luo Automation Engineering Division Shanghai Marine Diesel Engine Research Institute

Considering the problem of autonomous course-tracking of Unmanned Surface Vessel(USV) with uncertain systems,this paper put forwards a control method based on the clustering algorithm. The designed controller is composed of a clustering algorithm controller and a PID controller. Because of the uncertainty of the system, the clustering algorithm analysis controller online learned and classified the expected course to control the rudder, the PID controller adjusts the error. This method solves the problems of low control accuracy and poor control performance of robustness brought by the single system controller. By applying the proposed control method to the control design of USV autonomous course-tracking, the results of the simulation experiment show the effectiveness of the control method.
