Coherence thresholds in models of language change and evolution: the effects of noise, dynamics and network of interactions
J M Tavares, M M Telo da Gama, A Nunes
A simple model of language evolution, proposed in \cite{K_N}, is characterized by a pay-off in communicative function, and by an error in learning, that measures the accuracy in la…
Singular asymptotic expansions for Dirichlet eigenvalues and eigenfunctions of the Laplacian on thin planar domains
Denis Borisov, Pedro Freitas
We consider the Laplace operator with Dirichlet boundary conditions on a planar domain and study the effect that performing a scaling in one direction has on the spectrum. We deriv…
High-precision covariant one-boson-exchange potentials for np scattering below 350 MeV
Franz Gross, Alfred Stadler
Using the Covariant Spectator Theory (CST), we have found One-Boson-Exchange (OBE) potentials that fit the 2006 world np data below 350 MeV with a χ^2/N_data very close to 1, for a…
Moduli evolution in the presence of thermal corrections
T. Barreiro, B. de Carlos, E. J. Copeland +1
We study the effect of thermal corrections on the evolution of moduli in effective Supergravity models. This is motivated by previous results in the literature suggesting that thes…
Deducing the string-breaking distance in strong production processes
Eef van Beveren, George Rupp
We show that the string-breaking distance can be read from meson-production data, by employing a previously derived expression for the production amplitude. Accordingly, we find th…
Two-body scattering without angular-momentum decomposition
M. Rodriguez-Gallardo, A. Deltuva, E. Cravo +2
Two-body scattering is studied by solving the Lippmann-Schwinger equation in momentum space without angular-momentum decomposition for a local spin dependent short range interactio…
