Conformal transformation in theories
Rong-Jia Yang
It is well-known that theories are dynamically equivalent to a particular class of scalar-tensor theories. In analogy to the extension of the Einstein-Hilbert action…
Transformation between dense and sparse spirals in symmetrical bistable media
Ya-feng He, Bao-quan Ai, Bambi Hu
Transformation between dense and sparse spirals is studied numerically based on a bistable FitzHugh-Nagumo model. It is found that the dense spiral can transform into two types of…
Time-delayed-feedback control of pattern formation in symmetrical bistable media
Ya-feng He, Bao-quan, Bambi Hu
Effects of time-delayed-feedback on pattern formation are studied in symmetrical bistable media. The results show that the time delay alters the behavior of the front bifurcation r…
Enhancement of the longitudinal transport by a weakly transversal drive
Yafeng He, Baoquan Ai
Transport of Brownian particles in a two-dimensional asymmetric tube is investigated by applying a polarized field. From the Brownian dynamics simulations we find that the longitud…
Geometrical diagnostic for purely kinetic k-essence dark energy
Xiang-Ting Gao, Rong-Jia Yang
Geometrical diagnostic, involving the statefinder and , is widely used to discriminate different dark energy models. We apply the statefinder and …
Directed transport driven by Lévy flights coexisting with subdiffusion
Bao-quan Ai, Ya-feng He
Transport of the Brownian particles driven by Lévy flights coexisting with subdiffusion in asymmetric periodic potentials is investigated in the absence of any external driving for…
