Spinal cord injury can lead to severe sensory and motor dysfunction of limbs below the injury plane, which seriously affects the quality of life of patients. At present, the rehabilitation treatment methods for spinal cord injury are limited and the curative effect is not good. In order to seek a better treatment plan, some studies have tried to apply brain‐computer interface technology to the rehabilitation treatment of spinal cord injury and made certain progress. A review published in 2020 provides a systematic overview of the field, but less on the latest theories, techniques, and materials. On this basis, this paper adds an overview of the latest research progress of BCI technology, in order to let readers know the latest research trends in this field. In addition, the clinical application and challenges of this technology are briefly described, and a new prospect for the research and development of this field is further proposed to provide some reference and theoretical support for subsequent research.

For the purpose of improving the efficiency of cloud computing, by using of the research of the Job scheduling and resource management, the most important factor for the improving of the efficiency of the cloud, this paper used scheduling and management object to research the reference index as the statistical information system acquisition mode. The performance a-gent and server interface (PASI) method collected the row data for the cloud. The common security technology which applied in the cloud was passive defense methods, such as real-time active monitoring or deep packets inspection (DPI). The main purpose was to realize active inspection and defense. This paper proposed an effective framework to enhance comprehensive performance guideline of cloud computing center. It built the integrat framework based on the PASIe with DPI module, and put forward a Job dispatching and resource management module based on safe PASI (JDRMSP). Results of the experiment indicate that the model improves the efficiency of the cloud environment effectively. [ABSTRACT FROM AUTHOR]

At present, most of the Web service selection schemes based on QoS ignore the relationship between services and consider they are independent of each other, making the composite result deviation from the actual. In order to improve the accuracy of composite Web service, this paper considered the relationship between services impact on the composite Web service QoS, and studied of interface correlation, business correlation and statistic correlation three kinds of relationships between the services. This paper proposed a discovery method of the correlation-service set which based on correlation degree, transforming the correlation service selection problem into a mixed integer programming model. The experimental results show that considering the relationship between services will improve the quality of the composite Web services. [ABSTRACT FROM AUTHOR]

According to the motion characteristics and application requirements of port container terminal handling models, and combining with implementations and characteristics of serial communication, a monitoring and control system of S7-200 PLC and PC based on PPI communication has been designed in this paper. The paper formulates communication interface protocol, analyzes the design requirements of PLC side and PC side. The PLC program uses basic instruction and control relay instruction, and PC program is of Visual C+ + language. The system can stably and efficiently realize the monitoring and control of models in two interfaces. The separation of two monitoring modules appear in one interface, and the switching between two monitoring models are realized by two buttons which are in the interface. [ABSTRACT FROM AUTHOR]

In order to study the effect of the negative correlation of Pearson to collaborative filtering algorithm, this paper presented an improved collaborative filtering algorithm. Firstly this algorithm selected the positive and negative correlation users as the nearest neighbor set and furthest neighbor set respectively, and then made use of a tunable parameter to adjust the effect of the nearest and furthest neighbor set on recommendation. The experiment results on MovieLens dataset show that negative correlations can not only significantly improve the accuracy of recommendations, but also increase the diversity of recommendation lists. It has found that collaborative filtering algorithm by considering the negative correlations can greatly improve the recommendation accuracy of users with small degrees. This work suggests that the negative correlations help solve the dilemma of accuracy and diversity and cold start problem of the recommender systems. [ABSTRACT FROM AUTHOR]

To annotate the query result pages in Deep Web accurately and comprehensively, the domain ontology which can be seen as a global schema Web database to the annotation procedure is introduced in this paper. The Deep Web date is annotated through building the mapping in qurey interface mode, qurey result mode and domain notology. By collecting Web database from different domains, the experiments indicate that the proposed approach is highly effective. [ABSTRACT FROM AUTHOR]
