Entropy variation in a fractal phase space
O. Sotolongo-Costa, I. Rodríguez-Vargas
In this work, with the help of fractional calculus, it is shown a time dependence of entropy more general than the well known Pesin relation is derived. Here the equiprobability po…
Comment concerning Leonardo's rule
O. Sotolongo-Costa, L. M. Gaggero-Sager, T. Oseguera-Manzanilla +1
In this comment we propose a novel explanation for the Leonardo's rule concerning the tree branching. According to Leonardo's notebooks he observed that if one observes the branche…
Uphill solitary waves in granular flows
E. Martinez, C. Perez-Penichet, O. Sotolongo-Costa +4
We have experimentally observed a new phenomenon in the surface flow of a granular material. A heap is constructed by injecting sand between two vertical glass plates separated by…
A Bethe lattice representation for sandpiles
Oscar Sotolongo-Costa, Alexei Vazquez, J. C. Antoranz
Avalanches in sandpiles are represented throughout a process of percolation in a Bethe lattice with a feedback mechanism. The results indicate that the frequency spectrum and proba…
Diffusion regimes in Levy flights with trapping
Alexei Vazquez, Oscar Sotolongo Costa, Francois Brouers
The diffusion of a walk in the presence of traps is investigated. Different diffusion regimes are obtained considering the magnitude of the fluctuations in waiting times and jump d…
