Interplay between particle trapping and heterogeneity in anomalous diffusion
Haroldo V. Ribeiro, Angel A. Tateishi, Ervin K. Lenzi +2
Heterogeneous media diffusion is often described using position-dependent diffusion coefficients and estimated indirectly through mean squared displacement in experiments. This app…
Quenched and Annealed Disorder Mechanisms in Comb-Models with Fractional Operators
A. A. Tateishi, H. V. Ribeiro, T. Sandev +2
Recent experimental findings on anomalous diffusion have demanded novel models that combine annealed (temporal) and quenched (spatial or static) disorder mechanisms. The comb-model…
The role of fractional time-derivative operators on anomalous diffusion
Angel A. Tateishi, Haroldo V. Ribeiro, Ervin K. Lenzi
The generalized diffusion equations with fractional order derivatives have shown be quite efficient to describe the diffusion in complex systems, with the advantage of producing ex…
Characterization of river flow fluctuations via horizontal visibility graphs
A. C. Braga, L. G. A. Alves, L. S. Costa +4
We report on a large-scale characterization of river discharges by employing the network framework of the horizontal visibility graph. By mapping daily time series from 141 differe…
Investigating the interplay between mechanisms of anomalous diffusion via fractional Brownian walks on a comb-like structure
H. V. Ribeiro, A. A. Tateishi, L. G. A. Alves +2
The comb model is a simplified description for anomalous diffusion under geometric constraints. It represents particles spreading out in a two-dimensional space where the motions i…
The Transformation-Groupoid Structure of the q-Gaussian Family
Angel Akio Tateishi, Rudolf Hanel, Stefan Thurner
The q-Gaussian function emerges naturally in various applications of statistical mechanics of non-ergodic and complex systems. In particular it was shown that in the theory of bina…
Universal patterns in sound amplitudes of songs and music genres
R. S. Mendes, H. V. Ribeiro, F. C. M. Freire +2
We report a statistical analysis over more than eight thousand songs. Specifically, we investigate the probability distribution of the normalized sound amplitudes. Our findings see…
