Spontaneous ordering against an external field in nonequilibrium systems

J. C. Gonzalez-Avella, M. G. Cosenza, V. M. Eguiluz +1

We study the collective behavior of nonequilibrium systems subject to an external field with a dynamics characterized by the existence of non-interacting states. Aiming at explorin…

Transition from Pareto to Boltzmann-Gibbs behavior in a deterministic economic model

J. Gonzalez-Estevez, M. G. Cosenza, O. Alvarez-Llamoza +1

The one-dimensional deterministic economic model recently studied by Gonzalez-Estevez et al. [Physica A 387, 4367 (2008)] is considered on a two-dimensional square lattice with per…

Matroid polytopes and their volumes

Federico Ardila, Carolina Benedetti, Jeffrey Doker

We express the matroid polytope of a matroid as a signed Minkowski sum of simplices, and obtain a formula for the volume of . This gives a combinatorial expression f…

Gaslike model of social motility

A. Parravano, L. M. Reyes

We propose a model to represent the motility of social elements. The model is completely deterministic, possesses a small number of parameters, and exhibits a series of properties…

Disks around Brown Dwarfs in the Sigma Orionis Cluster

K. L. Luhman, J. Hernandez, J. J. Downes +2

We have performed a census of disks around brown dwarfs in the Sigma Ori cluster using all available images from IRAC onboard the Spitzer Space Telescope. To search for new low-mas…

A new search for variable stars in the globular cluster NGC 6366

A. Arellano Ferro, Sunetra Giridhar, V. Rojas Lopez +3

New CCD photometry of NGC 6366 has lead to the discovery of some variable stars. Two possible Anomalous Cepheids (or Pop II Cepheids), three long period variables, one SX Phe and o…
