The pion-kaon scattering amplitude constrained with forward dispersion relations up to 1.6 GeV

In this work we provide simple and precise parameterizations of the existing $\pi K$ scattering data from threshold up to 1.6 GeV, which are constrained to satisfy forward dispersion relations as well as three additional threshold sum rules. We also provide phenomenological values of the threshold parameters and of the resonance poles that appear in elastic scattering.Comment: References and comments added. Some errata corrected.

Determinación de factores influyentes sobre una respuesta en un dominio poco estructurado

This report focuses on results obtained from a classification technique applied to time series data in a medical ill-structured The statistical analysis and classification --in ill-structured-- of such data are often inadequate because of the intrinsic characteristics of those domains. The database in this analysis contains information relative to patients with major depressive disorders or esquizofrenia; as a consequence, a high quantity of database variables contain data corresponding to measures taken in different instant of time, making curves. For this reason we are motivated about how we can establish a useful classification technique of curves in a medical ill-structured domain.Postprint (published version
