Evaluación de herramientas para el desarrollo de servicios GRID

La tecnología Grid ha logrado insertarse en el mundo científico y en estos momentos se comienzan a ver implementaciones también en el mundo de negocios, debido al proceso de evolución de esta tecnología en los últimos años. El viejo deseo de compartir recursos e información que llevo a la interconexión de equipos y aplicaciones, cobra un nuevo impulso con la posibilidad de cumplir este deseo también a nivel global, y entre distintas organizaciones en forma cooperativa y coordinada. Grid posibilita la creación de sistemas que aprovechan esta capacidad dando lugar a sistemas distribuidos que antes eran demasiado complejos, tanto desde el punto de vista de sus objetivos como la calidad de servicio con la que pueden alcanzar estas metas.

Baryonic Resonances from Baryon Decuplet-Meson Octet Interactions and the Exotic Resonance S=1, I=1, J^P=3/2-

Using the lowest order chiral Lagrangian we study s-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons. We find two bound states in the flavour SU(3) limit corresponding to the octet and decuplet representations. These are found to split into eight different trajectories in the complex plane when the SU(3) symmetry is broken gradually. Finally, we are able to provide a reasonable description for a good number of 4-star 3/2- resonances listed by the Particle Data Group. In particular, the Xi(1820), the Lambda(1520) and the Sigma(1670) states are well reproduced. We predict a few other resonances and also evaluate the couplings of the observed resonances to the various channels from the residues at the poles of the scattering matrix from where partial decay widths into different channels can be evaluated.Comment: Talk given at 10th International Conference on the Structure of Baryons (Baryon 2004) at Palaiseau (France), 25-29 October 200

Simultaneous central nervous system complications of C. neoformans infection

The most common neurological manifestation of Cryptococcus neoformans infection is meningitis. Other less common manifestations include parenchymal central nervous system (CNS) granulomatous disease, hydrocephalus and stroke. C. neoformans is often suspected in immunodepressed patients, but it can be easily overlooked in otherwise healthy patients. This paper provides a detailed clinical description of a patient without immunosupression who developed multiple simultaneous neurological manifestations after the infection with C. neoformans

Chiral dynamics of hadrons in nuclei

In this talk I report on selected topics of hadron modification in the nuclear medium using the chiral unitary approach to describe the dynamics of the problems. I shall mention how antikaons, $\eta$, and $\phi$ are modified in the medium and will report upon different experiments done or planned to measure the $\phi$ width in the medium.Comment: 10 pgs, 3 figs.

Solid Polymer Electrolytes Based on Polylactic Acid Nanofiber Mats Coated with Polypyrrole

This is the peer reviewed version of the following article: Gisbert, F., García-Bernabé, A., Compañ, V., Martínez-Ramos, C., Monleón, M., Solid Polymer Electrolytes Based on Polylactic Acid Nanofiber Mats Coated with Polypyrrole. Macromol. Mater. Eng. 2021, 306, 2000584, which has been published in final form at https://doi.org/10.1002/mame.202000584. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.[EN] The production of electroconductive nanofiber membranes made from polylactic acid (PLA) coated with polypyrrole (PPy) is investigated, performing a scanning of different reaction parameters and studying their physicochemical and dielectric properties. Depending on PPy content, a transition between conduction mechanisms is observed, with a temperature-dependent relaxation process for samples without PPy, a temperature-independent conduction process for samples with high contents of PPy and a combination of both processes for samples with low contents of PPy. A homogeneous and continuous coating is achieved from 23 wt% PPy, observing a percolation effect around 27 wt% PPy. Higher wt% PPy allow to obtain higher conductivities, but PPy aggregates appear from 34% wt% PPy. The high conductivity values obtained for electrospun membranes both through-plane and in-plane (above 0.05 and 0.20 S cm¿1, respectively, at room temperature) for the highest wt% of PPy, their porous structure with high specific surface area and their thermal stability below 140 °C make them candidates for many potential applications as solid polymer electrolytes in, for example, batteries, supercapacitors, sensors, photosensors, or polymer electrolyte membrane fuel cells (PEMFCs). In addition, the biocompatibility of PLA-PPy membranes expand their potential applications also in the field of tissue engineering and implantable devices.The authors acknowledge financing from the Spanish Government's State Research Agency (AEI) through projects DPI2015-72863-EXP and RTI2018-095872-B-C22/ERDF.

Evaluación de tecnologías de portales para la publicación de servicios GRID

Un importante problema que encuentran las aplicaciones grid es la distancia que existe entre estas y los usuarios. Esta brecha puede ser acortada con el desarrollo de interfaces de usuario que oculten las complejidades del Grid. En este sentido los portales proveen una interfaz de usuario amigable y conocida que ayuda con esta tarea. El presente trabajo evalúa portales, portlets y frameworks de portales grid que pueden ser usados en el desarrollo de aplicaciones grid con el objetivo de acercar al usuario nal la tecnología Grid.VII Workshop de Procesamiento Distribuido y Paralelo (WPDP)Red de Universidades con Carreras en Informática (RedUNCI
