Analytical Model for wideband THz sources and detectors based on Optical Rectification and Electro-Optic Sampling
2013
An analytical model describing a laser based set-up for wideband THz generation and detection is presented. Particular attention is focused on the main broadband phenomena, which occur when THz radiations have to be handled.
Lo ausente como discurso : elipsis y fuera de campo en el texto cinematográfico
2003
RESUMEN El punto de partida es la oposición al modelo de representación institucional para buscar en elipsis y fuera de campo un camino desestabilizador que evidencie sus carencias y contradicciones más profundas mediante la plena asunción como discurso de lo ausente, lo no visible, a través de la connotación. Desde la tipología física, material, que aportan otras teorizaciones, se desarrolla una alternativa, abierta, que no sólo tiene capacidad para contemplar la perspectiva del modelo hegemónico sino que abre también el camino para una ruptura con él. La primera parte de la tesis está dedicada al establecimiento del marco teórico y del estado de la cuestión al tiempo que sitúa la perspect…

Limbal stem cells as a potential source of pancreatic beta cells
2009
BACKGROUND/RATIONAL Beta cell replacement therapy represents an alternative approach to conventional insulin regimen for the management of type 1 diabetes. Stem cells theoretically represent a suitable and renewable source of surrogate beta cells. Recently, it has been demonstrated that corneal epithelium contains stem cells in the basal layer of the limbus. Our aim was to isolate and characterize limbal stem cells (LSCs) from adult corneal-limbal biopsies, and to assess their capability to differentiate into insulin-producing cells. METHODS 2-3 mm2 biopsies were obtained from limbus and central cornea of four patients undergoing surgery for ocular diseases not involving conjuctive or corne…

Structure and performance assessment in traditional face-to-face and blended learning statistics courses
2014
Abstract In recent years the number of higher education institutions offering blended learning courses has increased notably. Blended learning is understood as the combination of traditional face-to-face teaching with online and distance learning. During the 2012- 13 academic year, for the first time, the Information and Documentation degree course at the University of Barcelona included a blended learning format in its course in statistics. The blended learning course combined biweekly face-to-face classes and online work between sessions. This study describes the organization of the blended course in comparison with the traditional face-to- face course and presents preliminary data on stu…
Recovery Capabilities of Rateless Codes on Simulated Turbulent Terrestrial Free Space Optics Channel Model
2013
Free Space Optics (FSO) links are affected by several impairments: optical turbulence, scattering, absorption, and pointing. In particular, atmospheric optical turbulence generates optical power fluctuations at the receiver that can degrade communications with fading events, especially in high data rate links. Innovative solutions require an improvement of FSO link performances, together with testing models and appropriate channel codes. In this paper, we describe a high-resolution time-correlated channel model able to predict random temporal fluctuations of optical signal irradiance caused by optical turbulence. Concerning the same channel, we also report simulation results on the error mi…
