Absorbing-state phase transitions with extremal dynamics
Ronald Dickman, Guilherme J. M. Garcia
Extremal dynamics represents a path to self-organized criticality in which the order parameter is tuned to a value of zero. The order parameter is associated with a phase transitio…
The Scaling of Maximum and Basal Metabolic Rates of Mammals and Birds
Lauro A. Barbosa, Guilherme J. M. Garcia, Jafferson K. L. da Silva
Allometric scaling is one of the most pervasive laws in biology. Its origin, however, is still a matter of dispute. Recent studies have established that maximum metabolic rate scal…
Asymmetric dynamics and critical behavior in the Bak-Sneppen model
Guilherme J. M. Garcia, Ronald Dickman
We investigate, using mean-field theory and simulation, the effect of asymmetry on the critical behavior and probability density of Bak-Sneppen models. Two kinds of anisotropy are…
On the thresholds, probability densities, and critical exponents of Bak-Sneppen-like models
Guilherme J. M. Garcia, Ronald Dickman
We report a simple method to accurately determine the threshold and the exponent of the Bak-Sneppen model and also investigate the BS universality class. For the random-neighbo…
On singular probability densities generated by extremal dynamics
Guilherme J. M. Garcia, Ronald Dickman
Extremal dynamics is the mechanism that drives the Bak-Sneppen model into a (self-organized) critical state, marked by a singular stationary probability density . With the ai…
Long-Bone Allometry of Terrestrial Mammals and the Geometric-Shape and Elastic-Force Constraints of Bone Evolution
V. B. Kokshenev, J. K. L. Silva, G. J. M. Garcia
A natural similarity in body dimensions of terrestrial animals noticed by ancient philosophers remains the main key to the problem of mammalian skeletal evolution with body mass ex…
