Response of electrically coupled spiking neurons: a cellular automaton approach
Lucas S. Furtado, Mauro Copelli
Experimental data suggest that some classes of spiking neurons in the first layers of sensory systems are electrically coupled via gap junctions or ephaptic interactions. When the…
Bounded fitness landscapes and the evolution of the linguistic diversity
Viviane M. de Oliveira, Paulo R. A. Campos, Marcelo A. F. Gomes +1
A simple spatial computer simulation model was recently introduced to study the evolution of the linguistic diversity. The model considers processes of selective geographic coloniz…
The bound state Aharonov-Bohm effect around a cosmic string revisited
C. Filgueiras, Fernando Moraes
In this article we observe that the self-adjoint extension of the Hamiltonian of a particle moving around a shielded cosmic string gives rise to a gravitational analogue of the bou…
Optimized suppression of coherent noise from seismic data using the Karhunen-Loeve transform
Raul Montagne, Giovani L. Vasconcelos
Signals obtained in land seismic surveys are usually contaminated with coherent noise, among which the ground roll (Rayleigh surface waves) is of major concern for it can severely…
Theoretical model for the evolution of the linguistic diversity
Viviane M. de Oliveira, M. A. F. Gomes, I. R. Tsang
Here we describe how some important scaling laws observed in the distribution of languages on Earth can emerge from a simple computer simulation. The proposed language dynamics inc…
Linear syzygies and birational combinatorics
Aron Simis, Rafael H. Villarreal
Let be a finite set of monomials of the same degree in a polynomial ring over an arbitrary field . We give some necessary and/or sufficient cond…
