Ordinal spectrum: a frequency domain characterization of complex time series
Mario Chavez, Johann H. Martinez
Although classical spectral analysis is a natural approach to characterise linear systems, it cannot describe a chaotic dynamics. Here, we propose the ordinal spectrum, a method ba…
Using symbolic networks to analyse dynamical properties of disease outbreaks
José L. Herrera-Diestra, Javier M. Buldú, Mario Chávez +1
We introduce a new methodology to analyze the evolution of epidemic time series, which is based on the construction of epidemic networks. First, we translate the time series into o…
In defence of the simple: Euclidean distance for comparing complex networks
Johann H. Martínez, Mario Chavez
To improve our understanding of connected systems, different tools derived from statistics, signal processing, information theory and statistical physics have been developed in the…
Functional brain networks reveal the existence of cognitive reserve and the interplay between network topology and dynamics
Johann H. Martínez, María E. López, Pedro Ariza +6
We investigated how the organization of functional brain networks was related to cognitive reserve (CR) during a memory task in healthy aging. We obtained the magnetoencephalograph…
Synchronization in Complex Networks: a Reply on a recent Comment
S. Boccaletti, M. Chavez, A. Amann +1
We clarify a number of points raised in [Matias, arXiv:cond-mat/0507471v2 (2005)].
