7 p, 1.7 MB Noncharacteristic half-lives in radioactive decay / Corral Cano, Álvaro (Centre de Recerca Matemàtica) ; Font Clos, Francesc (Centre de Recerca Matemàtica) ; Camacho Castro, Juan (Universitat Autònoma de Barcelona. Departament de Física)
Half-lives of radionuclides span more than 50 orders of magnitude. We characterize the probability distribution of this broad-range data set at the same time that we explore a method for fitting power laws and testing goodness-of-fit. [...]

Departament de Física) ; Llopis, Isaac (Universitat Autònoma de Barcelona. Grup de Física Estadística)
The problem of nonlinear Hamiltonian oscillators is one of the classical questions in physics. When an analytic solution is not possible, one can resort to obtaining a numerical solution or using perturbation theory around the linear problem. [...]

20 p, 1.8 MB Dynamics of one- and two-dimensional fronts in a bistable equation with time-delayed global feedback : propagation failure and control mechanisms / Boubendir, Yassine (New Jersey Institute of Technology. Department of Mathematical Sciences) ; Méndez López, Vicenç (Universitat Autònoma de Barcelona. Departament de Física) ; Rotstein, Horacio G. (New Jersey Institute of Technology. Department of Mathematical Sciences)
We study the evolution of fronts in a bistable equation with time-delayed global feedback in the fast reaction and slow diffusion regime. This equation generalizes the Hodgkin-Grafstein and Allen-Cahn equations. [...]

7 p, 207.1 KB Nonuniversality and the role of tails in reaction-subdiffusion fronts / Campos, Daniel (Universitat Autònoma de Barcelona. Departament de Física) ; Méndez López, Vicenç (Universitat Autònoma de Barcelona. Departament de Física)
Recently there has been a certain controversy about the scaling properties of reaction-subdiffusion fronts. Some works seem to suggest that these fronts should move with constant speed, as do classical reaction-diffusion fronts, while other authors have predicted propagation failure, i. [...]

The meaning of temperature in nonequilibrium thermodynamics is considered by using a forced harmonic oscillator in a heat bath, where we have two effective temperatures for the position and the momentum, respectively. [...]

Micellization is the precipitation of lipids from aqueous solution into aggregates with a broad distribution of aggregation number. Three eras of micellization are characterized in a simple kinetic model of Becker-Döring type. [...]

Departament de Física) ; Fort Viader, Joaquim (Universitat de Girona. Departament de Física) ; Llebot, Josep Enric, 1953- (Universitat Autònoma de Barcelona. Departament de Física)
A generalization of reaction-diffusion models to multigeneration biological species is presented. It is based on more complex random walks than those in previous approaches. The new model is developed analytically up to infinite order. [...]

6 p, 76.5 KB Shear-induced shift of spinodal line in entangled polymer blends / Criado-Sancho, Manuel (Universidad Nacional de Educación a Distancia (Espanya). Departamento de Ciencias y Técnicas Físicoquímicas) ; Jou i Mirabent, David, 1953- (Universitat Autònoma de Barcelona. Departament de Física) ; Casas Vázquez, José (Universitat Autònoma de Barcelona. Departament de Física) ; Castillo, L. F. del (Universidad Nacional Autónoma de México. Instituto de Investigaciones en Materiales)
We study the shear-flow effects on phase separation of entangled polymer blends by incorporating into the chemical potential a nonequilibrium contribution due to the flow. The results are compared with those of a previous analysis by other authors which did not modify the chemical potential but used a different assumption for the stress tensor of the blend.
