In its design, it describes the general design and the framework of the corpus, then it describes its construction including data collection, the standard for the sorted data, data selection, data digitalization, data tagging and data aligning. With the construction, it will not only realize purposes and functions of the corpus, but also provide others with ways or means to use the corpus and to establish such kind of corpus.展开更多

The method of upper-lower solution is implemented to show the existence of traveling wave solutions. In order to simplify the construction of an admissible pair of upper lower solution, the scheme of strictly con- tracting rectangle is applied. Finally, the minimal speed c＊ of traveling wave solutions of the model is characterized. If the wave speed is greater than c＊, we show the exis- tence of traveling wave solutions connecting trivial and positive equilibria by combining the upper and lower solutions with the contracting rectangle. On the other hand, if the wave speed is less than c＊, the non-existence of such solutions is also established. Furthermore, to illustrate our theoretical results, some numerical simulations are performed and biological meanings are interpreted.展开更多
