Adaptive learning and coloniality in birds
M. A. R. de Cara, O. Pla, F. Guinea +1
We introduce here three complementary models to analyze the role of predation pressure in avian coloniality. Different explanations have been proposed for the existence of colonial…
A model for predation pressure in colonial birds
J. L. Tella, M. A. R. de Cara, O. Pla +1
Different explanations have been proposed for the existence of colonial breeding behavior in birds, but field studies offer no conclusive results. We analyze the interplay between…
Energy radiation of moving cracks
S. Fratini, O. Pla, P. Gonzalez +2
The energy radiated by moving cracks in a discrete background is analyzed. The energy flow through a given surface is expressed in terms of a generalized Poynting vector. The veloc…
Straight cracks in dynamic brittle fracture
O. Pla, F. Guinea, E. Louis +2
We study the dynamics of cracks in brittle materials when the velocity of the crack is comparable to the sound velocity by means of lattice simulations. Inertial and damped dynamic…
Competition, efficiency and collective behavior in the "El Farol" bar model
M. A. R. de Cara, O. Pla, F. Guinea
The El Farol bar model, proposed to study the dynamics of competition of agents in a variety of contexts (W. B. Arthur, Amer. Econ. Assoc. Pap. and Proc. 84, 406 (1994)) is studied…
Linear stability analysis of the Hele-Shaw cell with lifting plates
S. -Z. Zhang, E. Louis, O. Pla +1
The first stages of finger formation in a Hele-Shaw cell with lifting plates are investigated by means of linear stability analysis. The equation of motion for the pressure field (…
