Estudio de la dinámica global para un modelo de Evasión-Inmune de un tumor cancerígeno

In this paper we study the global dynamics for a Tumor Immune-Evasion model proposed by Arciero, Jackson and Kirschner [1], which describes the interaction between effector cells, cancer cells, and the cytokines IL− 2 and TGF − β in the tumor site. This system describes different behaviors such as equilibrium points, periodic orbits, and stable limit cycles. By using the Localization of Compact...

Un enfoque gramatical para la extracción de términos índice

The extraction of the keywords that characterize a document in a given collection is one of the most important components of an Information Retrieval system. In this article, we propose to apply shallow parsing, implemented by means of cascades of finite-state transducers, to extract complex index terms based on an approximated grammar of Spanish. The coverage of the grammar is small but it all...

Desambiguación Verbal Automática: un estudio sobre el rendimiento de la información semántica argumental

One of the key tasks for resolving the ambiguity in the field of Natural Language Processing is Word Sense Disambiguation; especially the specific task of Verb Sense Disambiguation (VSD). In the present study an experimental task is performed in order to test the feasibility of an approach to VSD based on semantic information about verbal arguments. The good results obtained indicate the need t...

Un Enfoque Integrado para la Desambiguación

Resumen: En este art́ıculo presentamos una extensión de una arquitectura integrada diseñada originalmente para Semantic Parsing a WSD. El marco propuesto permitirá que ambas tareas puedan colaborar y llevarse a cabo simultáneamente. Se ha probado la validez y robustez de esta arquitectura contra una tarea de WSD bien definida (el SENSEVAL-II English Lexical Sample) aplicando modelos sintácticose...
