The authors analyzed the EGGs by using the maximum Lyapunov exponent （MLE）, which is one of the indices of the chaotic characteristics of time series. Significant differences were observed between the MLEs estimated from the, EGGs of the young and elderly individuals for most of the temporal intervals. The authors＇ data indicate that the EGGs of elderly gastrectomized subjects might be distinguished from the EGGs of healthy elderly individuals on the basis of the MLE distribution.展开更多

Music, broadly speaking, I think it should be the extension of culture, is a crystalline form of the essence which the culture conceived. This article discusses the musical and cultural ties, the characteristics of Chinese and Western musical culture, contacts the cultural background of Chinese and Western music culture, making more in-depth understanding.展开更多
