The minimum spanning tree (MST) model was applied to research the evolutionary relationships of tRNA gene sequences. The MSTs of tRNA gene sequences are constructed by the Prim's algorithm. The topology of the tRNA gene sequences-Ala, Leu, Met and Ser is discussed and shows the relationships among different kinds of tRNA sequences. The result of the MST shows they have the similar structure and behavior...
An improved mixed cellular automaton traffic flow model is proposed via considering the effects of the gap between the successive cars and the velocity on the stochastic delay probability on single lane, in which the stochastic delay probability can be classified into three ones: acceleration, follow and deceleration delay probability. By numerical simulation for the mixed traffic flow with different...
