La ULPGC en el volcán de El Hierro

[ES] Mesa redonda organizada por el Vicerrectorado de Cultura y Deporte de la Universidad de Las Palmas de Gran Canaria (ULPGC) en la que investigadores de distintos grupos de investigación que han participado en campañas en El Hierro exponen resultados obtenidos hasta el momento en torno a la erupción volcánica en octubre de 2011 en la Isla de El Hierro (Islas Canarias, España). Presenta el acto la Vicerrectora de Cultura y Deporte, Isabel Pascua Febles y modera el Director de Servicios de Apoyo a la I+D+I, José Antonio Carta González. Participan, Francisco José Pérez Torrado (GEOVOL), Antonio Juan González Ramos (División de robótica y oceanografía computacional, ROC-IUSIANI), Javier Arístegui Ruiz (Instituto Universitario de Oceanografía y Cambio Global), Magdalena Santana Casiano (QUIMA), Francisco Eugenio González (Grupo de procesado de imágenes y teledetección) y Ricardo Haroun Tabraue (Grupo de biodiversidad y conservación).

Entrevista al Dr. Javier Santaolalla, ingeniero de telecomunicación y fisico español, participante en las investigaciones del boson Higgs en el CERN.

Entrevista a Javier Santaolalla investigador en el experimento del CERN que describió recientemente una nueva partícula: el bosón de Higgs, que trata de explicar el origen de la masa de las partículas elementales. La existencia del bosón de Higgs y su campo asociado intentan explicar la razón de la existencia de masa en las partículas elementales. El 4 de julio de 2012, el CERN anunció la observación de una nueva partícula «consistente con el bosón de Higgs», pero se necesitaría más tiempo y datos para confirmarlo. El 14 de marzo de 2013 el CERN, con dos veces más datos de los que disponía en el anuncio del descubrimiento en julio de 2012, encontraron que la nueva partícula se ve cada vez más como el bosón de Higgs. Javier Santaolalla es ingeniero de telecomunicación por la Universidad de las Palmas de Gran Canaria y licenciado en ciencias físicas por la Universidad Complutense de Madrid. Investigador del CIEMAT (Madrid) y Dr. por esta última universidad en ciencias físicas. El Dr. Javier Santaolalla se encuentra unos días de escala en Las Palmas de Gran Canaria procedente de Brasil y con destino a Ginebra. Le agradecemos cuantas facilidades nos ha proporcionado en la realización de la presente entrevista así como sus aportaciones.

On the use of a low-cost thermal sensor to improve kinect people detection in a mobile robot

[EN]Detecting people is a key capability for robots that operate in populated environments. In this paper, we have adopted a hierarchical approach that combines classifiers created using supervised learning in order to identify whether a person is in the view-scope of the robot or not. Our approach makes use of vision, depth and thermal sensors mounted on top of a mobile platform.

Proposta di traduzione e analisi testuale del libro "El amor" di Raquel Diaz Reguera

Il presente elaborato intende offrire proposte di traduzione relative ad alcune tavole dell'albo illustrato El amor di Raquel Díaz Reguera.In particolare, sono state scelte quattro tavole, ciascuna appartenente a un genere testuale differente. L'intento è quello di confrontare ogni tavola alla rispettiva definizione di genere a cui appartiene. Lo scopo dell'intero lavoro è di offrire alcune traduzioni di un libro che ancora non è stato tradotto in italiano e di incuriosire un eventuale lettore verso il genere dell'albo illustrato di cui il bambino non è il solo destinatario finale.

Population doublings and percentage of S100-positive cells as predictors of in vitro chondrogenicity of expanded human articular chondrocytes

The aim of this study was to investigate the interconnection between the processes of proliferation, dedifferentiation, and intrinsic redifferentiation (chondrogenic) capacities of human articular chondrocyte (HAC), and to identify markers linking HAC dedifferentiation status with their chondrogenic potential. Cumulative population doublings (PD) of HAC expanded in monolayer culture were determined, and a threshold range of 3.57-4.19 PD was identified as indicative of HAC loss of intrinsic chondrogenic capacity in pellets incubated without added chondrogenic factors. While several specific gene and surface markers defined early HAC dedifferentiation process, no clear correlation with the loss of intrinsic chondrogenic potential could be established. CD90 expression during HAC monolayer culture revealed two subpopulations, with sorted CD90-negative cells showing lower proliferative capacity and higher chondrogenic potential compared to CD90-positive cells. Although these data further validated PD as critical for in vitro chondrogenesis, due to the early shift in expression, CD90 could not be considered for predicting chondrogenic potential of HAC expanded for several weeks. In contrast, an excellent mathematically modeled correlation was established between PD and the decline of HAC expressing the intracellular marker S100, providing a direct link between the number of cell divisions and dedifferentiation/loss of intrinsic chondrogenic capacity. Based on the dynamics of S100-positive HAC during expansion, we propose asymmetric cell division as a potential mechanism of HAC dedifferentiation, and S100 as a marker to assess chondrogenicity of HAC during expansion, of potential value for cell-based cartilage repair treatments.

The multiscenario multienvironment BioSecure Multimodal Database (BMDB)

A new multimodal biometric database designed and acquired within the framework of the European BioSecure Network of Excellence is presented. It is comprised of more than 600 individuals acquired simultaneously in three scenarios: 1) over the Internet, 2) in an office environment with desktop PC, and 3) in indoor/outdoor environments with mobile portable hardware. The three scenarios include a common part of audio/video data. Also, signature and fingerprint data have been acquired both with desktop PC and mobile portable hardware. Additionally, hand and iris data were acquired in the second scenario using desktop PC. Acquisition has been conducted by 11 European institutions. Additional features of the BioSecure Multimodal Database (BMDB) are: two acquisition sessions, several sensors in certain modalities, balanced gender and age distributions, multimodal realistic scenarios with simple and quick tasks per modality, cross-European diversity, availability of demographic data, and compatibility with other multimodal databases. The novel acquisition conditions of the BMDB allow us to perform new challenging research and evaluation of either monomodal or multimodal biometric systems, as in the recent BioSecure Multimodal Evaluation campaign. A description of this campaign including baseline results of individual modalities from the new database is also given. The database is expected to be available for research purposes through the BioSecure Association during 2008.
