It characterized by excessive adipose tissue accumulation in the body, which decreases patient’s life expectancy and has been associated higher incidence of chronic degenerative diseases, including type 2 diabetes mellitus, systemic arterial hypertension, cancer, cardiovascular disease.

In order to support a wide range of planning-related activities, we argue that plan and action representations must move to a more expressive language for goals and capabilities than is found in most current systems. A structured representation for capabilities can make explicit a hierarchy of capabilities based on subsumption, resulting in benefits for reasoning, representing, and acquiring op...

We introduce a test, named π-subsumption, which computes partial subsumptions between a hypothesis h and an example e, as well as a measure, the subsumption index, which quantifies the covering degree between h and e. The behavior of this measure is studied on the phase transition problem.

The original SPARQL proposal was often criticized for its inability to navigate through the structure of RDF documents. For this reason property paths were introduced in SPARQL 1.1, but up to date there are no theoretical studies examining how their addition to the language affects main computational tasks such as query evaluation, query containment, and query subsumption. In this paper we tack...
