Devil's staircase inside shrimp-shaped regions reveals periodicity of plateau spikes and bursts
Luiz F. B. Caixeta, Matheus H. P. Gonçalves, M. H. R. Tragtenberg +1
Slow-fast dynamics are intrinsically related to complex phenomena and are responsible for many of the homeostatic dynamics that keep biological systems healthy functioning. We stud…
Cardiac Reentry Modeled by Spatiotemporal Chaos in a Coupled Map Lattice
R. V. Stenzinger, M. H. R. Tragtenberg
Arrhythmias are potentially fatal disruptions to the normal heart rhythm, but their underlying dynamics is still poorly understood. Theoretical modeling is an important tool to fil…
Comment on "Convergence towards asymptotic state in 1-D mappings: A scaling investigation"
Mauricio Girardi-Schappo, M. H. R. Tragtenberg
Nonequilibrium phase transitions are characterized by the so-called critical exponents, each of which is related to a different observable. Systems that share the same set of value…
Measuring neuronal avalanches in disordered systems with absorbing states
Mauricio Girardi-Schappo, Marcelo H. R. Tragtenberg
Power-law-shaped avalanche-size distributions are widely used to probe for critical behavior in many different systems, particularly in neural networks. The definition of avalanche…
Kinetic theory and Brazilian income distribution
Igor D. S. Siciliani, Marcelo H. R. Tragtenberg
We investigate the Brazilian personal income distribution using data from National Household Sample Survey (PNAD), an annual research available by the Brazilian Institute of Geogra…
Information processing occurs via critical avalanches in a model of the primary visual cortex
G. S. Bortolotto, M. Girardi-Schappo, J. J. Gonsalves +2
We study a new biologically motivated model for the Macaque monkey primary visual cortex which presents power-law avalanches after a visual stimulus. The signal propagates through…
