Comparison of Methods for the Assessment of Nonlinearity in Short-Term Heart Rate Variability under different Physiopathological States
Luca Faes, Manuel Gòmez-Extremera, Riccardo Pernice +4
Despite the widespread diffusion of nonlinear methods for heart rate variability (HRV) analysis, the presence and the extent to which nonlinear dynamics contribute to short-term HR…
New class of level statistics in correlated disordered chains
Pedro Carpena, Pedro Bernaola-Galvan, Plamen Ch. Ivanov
We study the properties of the level statistics of 1D disordered systems with long-range spatial correlations. We find a threshold value in the degree of correlations below which i…
Effect of nonlinear filters on detrended fluctuation analysis
Z. Chen, K. Hu, P. Carpena +3
We investigate how various linear and nonlinear transformations affect the scaling properties of a signal, using the detrended fluctuation analysis (DFA). Specifically, we study th…
