Transforming Gaussian correlations. Applications to generating long-range power-law correlated time series with arbitrary distribution
Pedro Carpena, Pedro A. Bernaola-Galván, Manuel Gómez-Extremera +1
The observable outputs of many complex dynamical systems consist in time series exhibiting autocorrelation functions of great diversity of behaviors, including long-range power-law…
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…
Correlations in magnitude series to assess nonlinearities: application to multifractal models and heartbeat fluctuations
Pedro A. Bernaola-Galvan, Manuel Gomez-Extremera, A. Ramon Romance +1
The correlation properties of the magnitudes of a time series (sometimes called volatility) are associated with nonlinear and multifractal properties and have been applied in a gre…
A standalone version of IsoFinder for the computational prediction of isochores in genome sequences
Pedro Bernaola-Galván, Pedro Carpena, José L. Oliver
Isochores are long genome segments relatively homogeneous in G+C. A heuristic algorithm based on entropic segmentation has been developed by our group, and a web server implementin…
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…
