Recently, the concept of exponential sensitivity to initial conditions (ESIC) of deterministic chaos is generalized to power-law sensitivity to initial conditions (PSIC). We describe a general computational procedure to examine PSIC from a time series. Study of noise-free and noisy logistic and...

Detection of dynamical complexity changes in natural and man-made systems has deep scientific and practical meaning. We use the base-scale entropy method to analyze dynamical complexity changes for heart rate variability (HRV) series during specific traditional forms of Chinese Chi and Kundalini...
