Breakdown of self-organized criticality
Maria de Sousa Vieira
We introduce two sandpile models which show the same behavior of real sandpiles, that is, an almost self-organized critical behavior for small systems and the dominance of large av…
A simple deterministic self-organized critical system
Maria de Sousa Vieira
We introduce a new continuous cellular automaton that presents self-organized criticality. It is one-dimensional, totally deterministic, without any kind of embedded randomness, no…
Statistics of DNA sequences: a low frequency analysis
Maria de Sousa Vieira
We study statistical properties of DNA chains of thirteen microbial complete genomes. We find that the power spectrum of several of the sequences studied flattens off in the low fr…
Chaos and Synchronized Chaos in an Earthquake Model
Maria de Sousa Vieira
We show that chaos is present in the symmetric two-block Burridge-Knopoff model for earthquakes. This is in contrast with previous numerical studies, but in agreement with experime…
Nonuniversality of weak synchronization in chaotic systems
M. de Sousa Vieira, A. J. Lichtenberg
We show that the separate properties of weak synchronization (WS) and strong synchronization (SS), reported recently by Pyragas [K. Pyragas, Phys. Rev. E, 54, R4508 (1996)], in uni…
Exponential Distributions in a Mechanical Model for Earthquakes
Maria de Sousa Vieira
We study statistical distributions in a mechanical model for an earthquake fault introduced by Burridge and Knopoff [R. Burridge and L. Knopoff, {\sl Bull. Seismol. Soc. Am.} {\bf…
