The presented model takes account of the fact that any decision process—involving choosing at least between two options, in order to be physically realisable, needs to be coupled to some information negentropy source. This is in accordance with Brillouin's Principle (of information). In social...

We report the coupled effects of macroion charge discretization and counterion valence in the primitive model for spherical colloids. Instead of considering a uniformly charged surface, as it is traditionally done, we consider a more realistic situation where discrete monovalent microscopic...

We report on analytical results for a series of anisotropic driven systems in the context of a recently proposed Langevin equation approach. In a recent paper (P.L. Garrido et al., Phys. Rev. E 61 (2000) R4683) we have pointed out that entropic contributions, over-looked in previous works, are...

In the present work we consider the growth of a very dilute concentration of anisotropic particles, nucleated with random orientations, in a matrix of growing spherical particles. It is assumed that the matrix particles obey the usual JMAK kinetics. We concentrate on describing the change in...

This paper is concerned with the problem of ranking Lorenz curves in situations where the Lorenz curves intersect and no unambiguous ranking can be attained witout introducing weaker ranking criteria than first-degree Lorenz dominance. To deal with such situations two alternative sequences of...
