Time irreversibility and amplitude irreversibility measures for nonequilibrium processes
Wenpo Yao, Jun Wang, Matjaz Perc +4
Time irreversibility, which characterizes nonequilibrium processes, can be measured based on the probabilistic differences between symmetric vectors. To simplify the quantification…
Equal heartbeat intervals and their effects on the nonlinearity of permutation-based time irreversibility in heart rate
Yao Wen-po, Yao Wen-li, Wang Jun
The association of equal heartbeat intervals with cardiac conditions and the effect of the equality on permutation-based time irreversibility are investigated in this paper. We mea…
Time irreversibility and its application in epileptic brain electrical activities
Yao Wen-po, Yao wen-li, Dai Jia-fei +1
Time irreversibility (temporal asymmetry) is one of fundamental properties that characterize the nonlinearity of complex dynamical processes, and our brain is a typical complex dyn…
Double symbolic joint entropy in nonlinear dynamic complexity analysis
Wenpo Yao, Jun Wang
Symbolizations, the base of symbolic dynamic analysis, are classified as global static and local dynamic approaches which are combined by joint entropy in our works for nonlinear d…
