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…
Effects of coarse-graining on the scaling behavior of long-range correlated and anti-correlated signals
Yinlin Xu, Qianli D. Y. Ma, Daniel T. Schmitt +2
We investigate how various coarse-graining methods affect the scaling properties of long-range power-law correlated and anti-correlated signals, quantified by the detrended fluctua…
Effect of extreme data loss on long-range correlated and anti-correlated signals quantified by detrended fluctuation analysis
Qianli D. Y. Ma, Ronny P. Bartsch, Pedro Bernaola-Galván +2
We investigate how extreme loss of data affects the scaling behavior of long-range power-law correlated and anti-correlated signals applying the DFA method. We introduce a segmenta…
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…
Isochores Merit the Prefix 'Iso'
Wentian Li, Pedro Bernaola-Galvan, Pedro Carpena +1
The isochore concept in human genome sequence was challenged in an analysis by the International Human Genome Sequencing Consortium (IHGSC). We argue here that a statement in IGHSC…
Scale Invariance in the Nonstationarity of Physiological Signals
Pedro Bernaola-Galvan, Plamen Ch. Ivanov, Luis A. Nunes Amaral +2
We introduce a segmentation algorithm to probe temporal organization of heterogeneities in human heartbeat interval time series. We find that the lengths of segments with different…
