SBVR to OWL 2 Mappings - An Automatable and Structural-Rooted Aproach
La amplia aplicabilidad del mapeo de reglas de negocio en sentencias ontológicas ha sido recientemente reconocida. Algunas de las aplicaciones más importantes son: (1) la utilización de razonadores ontológicos para probar la consistencia de la información del dominio del negocio, (2) la generación de una ontología destinada a ser utilizada en la etapa de análisis del proceso de desarrollo de software, y (3) la posibilidad de encapsular la especificación declarativa del conocimiento del negocio en un sistema de información mediante la implementación de una ontología. El lenguaje denominado Semantics of Business Vocabulary and Business Rules (SBVR) brinda soporte a tal enfoque al proveer al experto del negocio una forma lingüistica de describir semánticamente los conceptos y especificar las reglas de negocio, en forma independiente al diseño del sistema de información. Aunque trabajos previos han presentado algunas propuestas, resta definir un enfoque exhaustivo y automatizable de tales mapeos. Este trabajo presenta un conjunto amplio y detallado de transformaciones que permiten la generación automatizable de una ontología implementada en OWL 2, partiendo de la especificación SBVR del dominio del negocio. Tales transformaciones están basadas en la especificación estructural de ambos estándars, y son descriptas mediante un caso de estudio. Se ha realizado un ejemplo real de validación, abordando la factibilidad de los mapeos mediante la evalución de la calidad de la ontología resultante.Wide applicability of mapping business rules expressions to ontology statements have already been recognized. Some of the most important applications are: (1) using of ontology reasoners to prove the consistency of business domain information, (2) generation of an ontology intended to be used in the analysis stage of a software development process, and (3) the possibility of encapsulate the declarative specication of business knowledge into information software systems by means of an implemented ontology. The Semantics of Business Vocabulary and Business Rules (SBVR) supports that approach by providing business people with a linguistic way to semantically describe business concepts and specify business rules in an independent way of any information system design. Previous work have presented some proposals but an exhaustive and automatable approach for them still is lacking. This work presents a broad and detailed set of transformations that allows the automatable generation of an OWL 2 ontology from the SBVR specications of a business domain. Such transformations are rooted on the structural specication of both standards and are depicted through a case study. A real case validation example was performed, approaching the feasibility of the mappings by the quality assessment of the developed ontology.Fil: Reynares, Emiliano.

A strategy for analyzing and enriching domain ontologies
During the last years there is an increasing interest on the ontologies. The way in which the semantics of a domain entity is represented in an ontology may di er depending on the requirements that the ontology should satisfy. However, in general the richness is a desired quality attribute for an ontology. The contribution of this paper is a strategy for evaluating and enriching the representation of real entity semantics in a domain ontology. In addition, an application example is discussed.Presentado en el II Workshop Innovación en Sistemas de Software (WISS)Red de Universidades con Carreras en Informática (RedUNCI
Individual and sex-related differences in pain and relief responsiveness are associated with differences in resting-state functional networks in healthy volunteers
Pain processing is associated with neural activity in a number of widespread brain regions. Here, we investigated whether functional connectivity at rest between these brain regions is associated with individual and sex-related differences in thermal pain and relief responsiveness. Twenty healthy volunteers (ten females) were scanned with functional magnetic resonance imaging in resting conditions. Half an hour after scanning, we administered thermal pain on the back of their right hand and collected pain and relief ratings in two separate runs of twelve stimuli each. Across the whole group, mean pain ratings were associated with decreased connectivity at rest between brain regions belonging to the default mode and the visual resting-state network. In men, pain measures correlated with increased connectivity within the visual resting-state network. In women, in contrast, decreased connectivity between this network and parietal and prefrontal brain regions implicated in affective cognitive control were associated with both pain and relief ratings. Our findings indicate that the well documented individual variability and sex differences in pain sensitivity may be explained, at least in part, by network dynamics at rest in these brain regions
Prototipo de un sistema de búsqueda de documentos basado en anotado semántico
Gran parte del conocimiento presente en las empresas se encuentra almacenado en objetos de conocimiento. Estos objetos deben ser administrados por una plataforma de gestión de conocimiento en su representación original a fin de facilitar su correcto acceso. Para ello, se debe capturar la semántica de su contenido y proveer herramientas para realizar búsquedas inteligentes. En este contexto, se estableció una vinculación entre el CIDISI, la Fundación Sadosky y la empresa Accion Point S.A. para desarrollar una plataforma prototipo que facilite la búsqueda de documentos asociados a los productos que comercializan. Este trabajo describe la experiencia de un proceso de Desarrollo de un Sistema de gestión de documentos basado en una red de ontologías.Sociedad Argentina de Informática e Investigación Operativ

Mast cells partly contribute to allergic enteritis development: Findings in two different mast cell-deficient mice
Allergic enteritis (AE) is a gastrointestinal form of food allergy. The presence of mast cells and granulocytes has been detected in the inflamed tissues in AE. In this study, we aimed to elucidate the role of mast cells in AE development using two mast cell-deficient mouse strains: KIT(W-sh/W-sh) bearing the W-sash (W(sh)) inversion mutation and Cpa3Cre/+, which lack mast cells due to Cre-mediated mast cell eradication, were used in an AE experimental model. The development of clinical symptoms (e.g. drop in body temperature and weight loss) were abolished in both strains, whereas inflammatory levels of AE (e.g. villous atrophy, edema, and granulocyte accumulation) were reduced mainly in KITW-sh/W-sh mice. FACS analysis of the KITW-sh/W-sh intestinal lamina propria, showed a reduction in the eosinophil (CD45+CD11b+SiglecF+cells) and neutrophil (CD45+CD11b+SiglecF−Ly6G+ cells) accumulation. Cpa3Cre/+ mice showed reduced eosinophil (CD45+CD11b+SiglecF+cells) accumulation, but neutrophil (CD45+CD11b+SiglecF−Ly6G+ cells) accumulation was retained at AE sites. The concentrations of CC chemokine ligand 1 (CCL1), a known CC chemokine receptor 8 ligand leading to eosinophil recruitment, was reduced in intestinal homogenates of both mast cell-deficient mouse strains. These results suggest that mast cells play a role in AE development in part by expressing CCL1 and contributing to eosinophil accumulation at AE. This study offers implications for establishing AE treatments that target infiltrating leucocytes in AE tissues.Fil: Blanco Pérez, Frank. No especifíca;Fil: Gonzalez Menendez, Irene.

The production of tt‾ , W+bb‾ and W+cc‾ is studied in the forward region of proton–proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of 1.98±0.02 fb−1 . The W bosons are reconstructed in the decays W→ℓν , where ℓ denotes muon or electron, while the b and c quarks are reconstructed as jets. All measured cross-sections are in agreement with next-to-leading-order Standard Model predictions.The production of , and is studied in the forward region of proton-proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated luminosity of 1.98 0.02 \mbox{fb}^{-1}.

A study of CP violation in B-+/- -> DK +/- and B-+/- -> D pi(+/-) decays with D -> (KSK +/-)-K-0 pi(-/+) final states
A first study of CP violation in the decay modes and , where labels a or meson and labels a or meson, is performed. The analysis uses the LHCb data set collected in collisions, corresponding to an integrated luminosity of 3 fb. The analysis is sensitive to the CP-violating CKM phase through seven observables: one charge asymmetry in each of the four modes and three ratios of the charge-integrated yields. The results are consistent with measurements of using other decay modes
