Threshold distribution of equal states for quantitative amplitude fluctuations
Yao Wenpo, Yao Wenli, Wang Jun
Objective. The distribution of equal states (DES) quantifies amplitude fluctuations in biomedical signals. However, under certain conditions, such as a high resolution of data coll…
Comparative analysis of time irreversibility and amplitude irreversibility based on joint permutation
Wenpo Yao, Wenli Yao, Rongshuang Xu +1
Although time irreversibility (TIR) and amplitude irreversibility (AIR) are relevant concepts for nonequilibrium analysis, their association has received little attention. This pap…
A novel parameter for nonequilibrium analysis in reconstructed state spaces
Wenpo Yao, Wenli Yao, Jun Wang
Kernel methods are widely used for probability estimation by measuring the distribution of low-passed vector distances in reconstructed state spaces. However, the information conve…
Comparative analysis of the original and amplitude permutations
Wenpo Yao, Wenli Yao, Jun Wang
The original and amplitude permutations are two basic ordinal patterns; however, their relationship has received little attention. This paper compares the original and amplitude pe…
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…
Quantifying time irreversibility using probabilistic differences between symmetric permutations
Wenpo Yao, Wenli Yao, Jun Wang +1
To simplify the quantification of time irreversibility, we employ order patterns instead of the raw multi-dimension vectors in time series, and considering the existence of forbidd…
