Malignant pheochromocytoma in a pig
(2011)Abstract. Endocrine tumors are rarely observed in pigs, and pheochromocytomas have been only punctually described. The current report describes a white and firm, 15-cm in diameter, neoplastic mass ... -
Skewed expression and up-regulation of the IL-12 and IL-18 receptors in resting and activated CD4 T cells from HIV-1-infected patients
(2007)IL-12 and IL-18 synergistically induce the production of IFN- by resting and activated T cells. To evaluate whether this induction was affected in HIV-1-infected patients, PBMC or isolated CD4 T ... -
Gene Ontology Function prediction in Mollicutes using Protein-Protein Association Networks
(2011)Abstract Background: Many complex systems can be represented and analysed as networks. The recent availability of large-scale datasets, has made it possible to elucidate some of the organisational ... -
Infinitely many periodic orbits for the rhomboidal five-body problem
(2006)We prove the existence of infinitely many symmetric periodic orbits for a regularized rhomboidal five-body problem with four small masses placed at the vertices of a rhombus centered in the fifth mass. ... -
Families of periodic orbits for the spatial isosceles 3-body problem
(2004)We study the families of periodic orbits of the spatial isosceles 3-body problem (for small enough values of the mass lying on the symmetry axis) coming via the analytic continuation method from ... -
Estudi de la població de Spiraea crenata subsp. parvifolia (Rosaceae) del Collsacabra
(2011)Spiraea crenata subsp. parvifolia és un tàxon endèmic del nord-est ibèric, que té una de les escasses poblacions conegudes al Collsacabra, Osona. En aquest treball es pretén definir l’extensió ... -
The number of planar central configurations for the 4-body problem is finite when 3 mass positions are fixed
(2005)In the n{body problem a central con guration is formed when the position vector of each particle with respect to the center of mass is a common scalar multiple of its acceleration vector. Lindstrom ... -
FAM-MDR: a flexible family-based multifactor dimensionality reduction technique to detect epistasis using related individuals
(2010-04)We propose a novel multifactor dimensionality reduction method for epistasis detection in small or extended pedigrees, FAM-MDR. It combines features of the Genome-wide Rapid Association using Mixed ... -
Self-organization mechanisms for the formation on nearshore crescentic and transverse sand bars
(2002)The formation and development of transverse and crescentic sand bars in the coastal marine environment has been investigated by means of a nonlinear numerical model based on the shallow-water equations ... -
A subcritical instability of wave-driven alongshore currents
(2004)The development of shear instabilities of a wave-driven alongshore current is investigated. In particular, we use weakly nonlinear theory to investigate the possibility that such instabilities, which ... -
Monotonic AC-Compatible Semantic Path Orderings
(2003)Abstract. Polynomial interpretations and RPO-like orderings allow one to prove termination of Associative and Commutative (AC-)rewriting by only checkingthe rules of the given rewrite system. However, ... -
Frontshear and backshear instabilities of the mean longshore current
(2001)An analytical model based on Bowen and Holman [1989] is used to prove the existence of instabilities due to the presence of a second extremum of the background vorticity at the front side of the ... -
Complete Monotonic Semantic Path Orderings
(2000)Although theoretically it is very powerful, the semantic path ordering (SPO) is not so udeful in practice, since its monotonicity has to be proved by hand for each concrete term rewrite system (TRS). ... -
Generation and nonlinear evolution of shore-oblique/transverse sand bars
(2006)The coupling between topography, waves and currents in the surf zone may selforganize to produce the formation of shore-transverse or shore-oblique sand bars on an otherwise alongshore uniform beach. ... -
SAT Modulo Linear Arithmetic for Solving Polynomial
(2012-10-04)Polynomial constraint solving plays a prominent role in several areas of hardware and software analysis and verification, e.g., termination proving, program invariant generation and hybrid system ... -
Mujeres emprendedoras en internet: una revisión de la literatura
(2012)Los estudios sobre emprendimiento desde la perspectiva de género, es un ámbito que ha ido incrementado en los últimos años, la evidencia que más del 50% de la población mundial son mujeres pero que ... -
El Diseño: 7 visiones transversales
(2012)El diseño ha evolucionado de manera sorprendente en las últimos años gracias a la tecnología, potenciando diferentes disciplinas y especializaciones en las que influyen aspectos técnicos y de percepción ... -
m-Todos, tendencias y oportunidades de la movilidad digital
(2011-12)La difusión de la tercera generación de dispositivos móviles y su integración con la World Wide Web son un reto para los medios de comunicación. Como en cualquier otro ecosistema, la llegada de una ... -
La Crítica literària feminista
(2010-02-12)Conferència emmarcada dins la tercera edició del 'Cicle de conferències en perspectiva de gènere' en la qual la Dra. Francesca Bartina proposa un viatge per les diferents possibilitats hermenèutiques ... -
La premsa comarcal i el consum de noves pantalles
(2012-05)La investigació es centra en la visió dels mitjans de proximitat i el consum de d’aquests mitjans en el marc de la convergència digital a Catalunya. No és cap misteri l’aparició de nous hàbits de consum ...
