La estabilidad como mecanismo de selección natural sobre redes de interacción en sistemas biológicos =
(2011)
En este trabajo de investigación se propone un mecanismo evolutivo de carácter muy general que resulta en una posible explicación a la ubiquidad de ciertas propiedades de las redes de interacción en una gran variedad de ...
Locating invariant tori for a family of two-dimensional Hamiltonian mappings
(2011-10-15)
The location of invariant tori for a two-dimensional Hamiltonian mapping exhibiting mixed phase space is discussed. The phase space of the mapping shows a large chaotic sea surrounding periodic islands and limited by a set ...
Chaotic diffusion for particles moving in a time dependent potential well
(2020-10-09)
The chaotic diffusion for particles moving in a time dependent potential well is described by using two different procedures: (i) via direct evolution of the mapping describing the dynamics and; (ii) by the solution of the ...
Dynamic scaling of polymer gels comprising nanoparticles

The friendship paradox in scale-free network
(Hikari Ltd.Ruse, 2014)
Our friends have more friends than we do. That is the basis of the friendship paradox. In mathematical terms, the mean number of friends of friends is higher than the mean number of friends. In the present study, we analyzed ...
Scaling relative incentive value in consummatory behavior
(Academic Press, 2006-11)
Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments ...
Fourier´s law from a chain of coupled anharmonic oscillators under energy conserving shot noise.
(Águas de Lindóia, 2013-05)
We analyze the transport of heat along a chain of particles interacting through anharmonic potentials consisting of quartic terms in addition to harmonic quadratic terms and subject to heat reservoirs at its ends. Each ...
