Cooperative peer-to-peer multiagent-based systems.
TLDR
In this study, strong cooperation is allowed among agents having similar sizes, and weak cooperation if agents have markedly different "sizes", thus establishing a peer-to-peer modulated interaction scheme. Expand

Dynamic peer-to-peer competition
The dynamic behavior of a multiagent system in which the agent size si is variable it is studied along a Lotka–Volterra approach. The agent size has hereby the meaning of the fraction of a givenExpand

Separation of statistically dependent sources using an L2-distance non-Gaussianity measure
TLDR
We propose the MaxNG algorithm based on the maximization of a non-Gaussianity (NG) measure which is equivalent to minimizing the Shannon entropy of source estimates. Expand

A semiclassical statistical model for quantum dissipation
The dynamical problem posed by the coupling of quantal to classical degrees of freedom is tackled, within the framework of the quantum friction phenomenon, by recourse to statistical methods embeddedExpand

Blind spectral unmixing by local maximization of non-Gaussianity
TLDR
We approach the estimation of material percentages per pixel (endmember fractional abundances) in hyperspectral remote-sensed images as a blind source separation problem. Expand

Separation of statistically dependent sources using an L 2 -distance non-Gaussianity measure
We provide a solution to the BSS problem for the special case of statistically dependent sources. We propose the MaxNG algorithm based on the maximization of a non-Gaussianity (NG) measure which isExpand

QUANTITATIVE INDICATOR FOR SEMIQUANTUM CHAOS
Brief Reports are accounts of completed research which do not warrant regular articles or the priority handling given to Rapid Com-munications; however, the same standards of scientific quality apply.Expand

Nontrivial dynamics induced by a nonlinear Jaynes-Cummings Hamiltonian
Abstract The addition of a nonlinear term to the Jaynes-Cummings Hamiltonian induced a nontrivial discrete dynamics for the number of possible transitions of a given order, represented by a FibonacciExpand

Quantal friction, nonlinear Hamiltonians, and information theory
Information theory ideas together with entropy dynamical properties are combined in order to formulate a new algorithm for the treatment of non-linear Hamiltonians, whether time dependent or not. TheExpand
