1. Whole-cell voltage-clamp techniques were used to record K+ currents in relay neurons (RNs) that had been acutely isolated from rat thalamic ventrobasal complex and maintained at 23 degrees C in vitro. Tetrodoxin (TTX; 0.5 microM) was used to block Na+ currents, and reduced extracellular levels of Ca2+ (1 mM) were used to minimize contributions from Ca2+ current (ICa). 2. In RNs, depolarizing...

A new kinetic model for binary mixtures and its Lattice Boltzman (LB) discretization is presented. In the hydrodynamic limit the model recovers the Navier-Stokes and the Stefan-Maxwell binary diffusion equations. The thermodynamic consistency is ensured by the defined non-negative entropy production within the domain of applicability of the model. The present formulation is able to simulate mix...

We have discussed thermodynamical and magnetic properties of the grand-canonical ensembles of the half-filled two-site Hubbard model within the framework of the nonextensive statistics (NES). For relating the physical temperature T to the Lagrange multiplier β, two methods have been adopted: T = 1/k B β in the method A [Tsallis et al. Physica A 261 (1998) 534], and T = c q /k B β in the method ...

We have discussed thermodynamical and magnetic properties of the grandcanonical ensembles of the half-filled, two-site Hubbard model within the framework of the nonextensive statistics (NES). For relating the physical temperature T to the Lagrange multiplier β, two methods have been adopted: T = 1/kBβ in the method A [Tsallis et al. Physica A 261 (1998) 534], and T = cq/kBβ in the method B [Abe...

In this paper a new, simple approach to solving combinatorial optimization problems is discussed and preliminary simulation results are presented. The Pulsed Noise Model (PNM) introduced in the paper is based on combining the Langevin Equation minimization method with the Hopfield model, in a very straightforward manner. The main advantage of this approach is its conceptual simplicity without s...

The adsorption of ions at the interface between two immiscible electrolyte solutions (ITIES) is primarily controlled by the potential distribution across the interface, which in turn is influenced by the adsorption process. In the present paper, we simulate the effect of the adsorption of charged species on the charge distribution at the ITIES based on the classical description of the interface...

The thermodynamical property of a small cluster including M Hubbard dimers, each of which is described by the two-site Hubbard model, has been discussed within the nonex-tensive statistics (NES). We have calculated temperature and magnetic-field dependences of the specific heat and susceptibility for M = 1, 2, 3 and ∞, assuming the relation between M and the entropic index q given by q = 1 + 1/...
