Velocity effect and critical velocity are incorporated into the average space gap cellular automaton model [J.F. Tian, et al., Phys. A 391 (2012) 3129], which was able to reproduce many spatiotemporal dynamics reported by the three-phase theory except the synchronized outflow of wide moving jams. The physics of traffic breakdown has been explained. Various congested patterns induced by the on-ramp...
By applying nonequilibrium Greenʼs functions in combination with the density-functional theory, we investigate the transport properties of single-polyaniline molecular devices. The results show that these devices can perform a reversible switching behavior by oxidation/reduction, which agrees well with the experimental results. In addition, a rectifying performance is only found in the device on emeraldine...
