Starting from a quite universal formula, which is obtained by variable separation approach and valid for many (2+1)-dimensional nonlinear physical models, a new general type of solitary wave, i.e., semifolded solitary waves (SFSWs) and semifoldons, is defined and studied. We investigate the...

A field experiment was conducted to evaluate the effects of temperature on winter wheat (Triticum aestivum L.) at the Tongwei County (35°13'N, 105°14'E), Gansu, in the semiarid northwest of China from 2006 to 2008. Two study sites were chosen: one at Tongwei experimental station, situated...

We show that the delayed feedback neural networks for storing limit cycles can be trained using a global training algorithm. It is found that the storage capacity of the networks is in proportion to delay length as in the networks trained by the correlation learning based on Hebb's rule, but is...

Stochastic differential equations, especially the one called Langevin equation, play an important role in many fields of modern science. In this paper, we use the bicolour rooted tree method, which is based on the stochastic Taylor expansion, to get the systematic pattern of the high order...
