Synchronization of multi-phase oscillators: An Axelrod-inspired model (2008)
Kuperman, M. N., Zanette, D. H.
Inspired by Axelrod's model of culture dissemination, we introduce and analyze a model for a population of coupled oscillators where different levels of synchronization can be assimilated to...
Kuperman, M. N., Kenkre, V. M.
We study the dynamics of the transmission of the hanta virus infection among mouse populations, taking into account, simultaneously, seasonal variations of the environment and interactions within two...
Theory of possible effects of the Allee phenomenon on refugia of the Hantavirus epidemic (2008)
Kumar, Niraj, Kuperman, M. N., Kenkre, V. M.
We investigate possible effects of high order nonlinearities on the shapes of infection refugia of the Hantavirus epidemic. We replace Fisher-like equations that have been recently used to describe...
The effect of the topology on the spatial ultimatum game (2007)
Kuperman, M. N., Gusman, S. Risau
In this work we present an analysis of a spatially non homogeneous ultimatum game. By considering different underlying topologies as substrates on top of which the game takes place we obtain...
Affinity driven social networks (2007)
In this work we present a model for evolving networks, where the driven force is related to the social affinity between individuals in a population. In the model, a set of individuals initially...
Fuentes, M. A., Kuperman, M. N., Iglesias, J. R.
Different models to study the wealth distribution in an artificial society have considered a transactional dynamics as the driving force. Those models include a risk aversion factor, but also a...
Cultural propagation on social networks (2005)
In this work we present a model for the propagation of culture on networks of different topology and by considering different underlying dynamics. We extend a previous model proposed by Axelrod by...
Dynamic Domains Networks (2004)
Kuperman, M. N., Ballard, M., Laguna, M. F.
We present a model for the description of the evolution of contacts among individuals in a network. At each time step each individual is associated with a domain or neighborhood of fully connected...
Periodically Varying Externally Imposed Environmental Effects on Population Dynamics (2004)
Ballard, M., Kenkre, V. M., Kuperman, M. N.
Effects of externally imposed periodic changes in the environment on population dynamics are studied with the help of a simple model. The environmental changes are represented by the temporal and...
Fuentes, M. A., Kuperman, M. N., Kenkre, V. M.
Simple analytic considerations are applied to recently discovered patterns in a generalized Fisher equation for population dynamics. The generalization consists of the inclusion of non-local...
Non-local Interaction Effects on Pattern Formation in Population Dynamics (2003)
Fuentes, M. A., Kuperman, M. N., Kenkre, V. M.
We consider a model for population dynamics such as for the evolution of bacterial colonies which is of the Fisher type but where the competitive interaction among individuals is non-local, and show...
Applicability of the Fisher Equation to Bacterial Population Dynamics (2002)
Kenkre, V. M., Kuperman, M. N.
The applicability of the Fisher equation, which combines diffusion with logistic nonlinearity, to population dynamics of bacterial colonies is studied with the help of explicit analytic solutions for...
Fuentes, M., Kuperman, M. N., Boissonade, J., Dulos, E., Gauffre, F., De Kepper, P.
We both show experimentally and numerically that the time scales separation introduced by long range activation can induce oscillations and excitability in nonequilibrium reaction-diffusion systems...
Experimental evidence of stochastic resonance without tuning due to non Gaussian noises (2001)
Castro, F. J., Kuperman, M. N., Fuentes, M., Wio, H. S.
In order to test theoretical predictions, we have studied the phenomenon of stochastic resonance in an electronic experimental system driven by white non Gaussian noise. In agreement with the...
M. A. Fuentes, M. N. Kuperman, J. R. Iglesias
Different models to study the wealth distribution in an artificial society have considered a transactional dynamics as the driving force. Those models include a risk aversion factor, but also a...
