Abstract-To study the effect of Xiaoyaosan on changes of behaviors (the open field test, elevated plus maze test and Y-maze test) in chronic immobilization stress (CIS) rats. Methods: 28 male Sprague-Dawley rats were randomly divided into control group, model group and Xiaoyaosan group. CIS was used to induce stress in rats of model group and Xiaoyaosan group, 3 h a day for 21 days. Xiaoyaosan was...
Spectrum sensing is a crucial technology for cognitive radio networks. In this paper, we develop a novel spectrum sensing method for secondary users to sense the idle spectrum. The key idea of the proposed method is combining multiple slots energy detection. Firstly, we establish the probability model regarding the appearance of the primary user at each slot of a secondary user slots window structure...
In this paper, we study solutions of general matrix equations by using the iterative method and present gradient-based iterative algorithms by applying the hierarchical identification principle. Convergence analysis indicates that the iterative solutions always converge fast to the exact solutions for any initial values and small condition numbers of the associated matrices. Several numerical examples...
Wireless sensor nodes have the advantages of low-cost, easy deployment and mobility. If they are deployed underground mine, with the existing underground cable transmission systems, wireless sensor network can improve the mine information greatly. The paper is to find the relationship between signal quality/packets loss rate and distance by the test in coal mine. The result can be as a reference for...
Communication systems are becoming more complex due to the advancements and heterogeneity in device and network technologies. The diversity of content and services offered to users is increasing and services have become an important source of revenue for network operators. However, the success of service providers depends on the adaptability of their services to user environments and preferences....
