A novel method for analysis of transient morphological changes in quasiperiodic physiological signals and their neurogenic correlates
Tomasz Gradowski, Damian Waląg, Tomir Domański +1
Conventional ECG visualization and analysis methods typically emphasize either waveform morphology or rhythm variability. This work presents a visualization framework for quasiperi…

Type I intermittency in a dynamical system with dichotomous parameter change
J. J. Zebrowski, R. Baranowski
In type I intermittency, simple models known for at least twenty years show that a characteristic u-shaped probability distribution is obtained for the laminar phase length. We hav…
