By analyzing the co-seismic responses,we found that firstly there was essentially a linear correlation between response time and epicentral distance. Secondly, there was some correlation between maximum response amplitude and earthquake magnitude as well as between the duration and earthquake magnitude. Thirdly, the response amplitudes and decay rates were different for different types of instruments. Due to less data-sampling frequency, the deformation instruments, could not display the first motion of P and S waves, but responded mainly to far-field surface waves. Before the earthquake, the NS earthtide component recorded by the cave stainmeter at Yichang was distorted for nearly eight hours. While digital deformation observation did not show complete information about the earthquake source, it still reflected some key features of seismic-wave propagation.展开更多

There are many evidences that during the process of spreading Buddhism in the Far East and South-East Asia, the principles of Buddhist doctrine became a part of the state ideology in many cases due to the patronage of the powerful laywomen. In Japan, thanks to the activity of empresses Suiko （597-628）, Jito （645-703） and Koken （718-770）. Buddhism could integrate into the system of traditional religion Shinto, developing further into Shinto-Buddhist syncretism. During the reign of Suiko about a hundred of the Buddhists, temples have been constructed through all the country and a system of religious bureaucracy ＂Sogo＂ was founded. Empress Jito took part in religious reforms during the second half of VII century and sent Buddhist missionaries to the local aborigines haya to and emishi. Empress Koken after the death of her father-emperor Shomu continued his policy to constructing the state ideology on the basis of Buddhism and was the first ruler in the history of early-medieval Japan, who permitted Buddhists to take part in the Shinto ceremonies. Therefore, the study of the role of empresses in spreading of Buddhism in Japan is important for understanding the history of religious and cultural traditions in Japan.展开更多

The model consists of four delay differential equations. Stability of the disease free equilibrium and the existence of an endemic equilibrium for this model are stated in terms of a key threshold parameter. The study of dynamics for the model shows that the endemic equilibrium is globally stable in an open region if it exists and there is no delays, and for some nonzero delays the endemic equilibrium undergoes Hopf bifurcation and a periodic orbit emerges. Some numerical results are provided to support the theoretic results in this paper. These results suggest that prepatent periods in infection affect the prevalence of schistosomiasis, and it is an effective strategy on schistosomiasis control to lengthen in prepatent period on infected definitive hosts by drug treatment （or lengthen in prepatent period on infected intermediate snails by lower water temperature）.展开更多
