Mobile satellite networks are now being utilized to provide complementary service coverage to their terrestrial counterparts. The migration from voice-dominated service delivery to a data-centric environment implies that the choice of one particular access network over another will need to take into account many different criteria, which previously need not(More)
We have created a transgenic mouse with a hypomorphic allele of the vesicular monoamine transporter 2 (Vmat2) gene by gene targeting. These mice (KA1) have profound changes in monoamine metabolism and function and survive into adulthood. Specifically, these animals express very low levels of VMAT2, an endogenous protein which sequesters monoamines(More)
The broadband satellite multimedia (BSM) architecture standardised by ETSI defines a satellite independent service access point (SI-SAP) interface layer that separates the satellite independent features of the upper layers from the satellite dependant features of the lower layers, and provides a mechanism to carry IP-based protocols over these satellite(More)
Vehicle to vehicle communication has strong potential to be a mechanism to improve driver’s safety and is now emerging as a prominent research area all over the world. At present, vehicular networks are still not considered to be very efficient because of their rapid topology changes and their highly dynamic structure. However, there has been(More)
SUMMARY This is the second part of the tutorial paper following the previous tutorial paper describing enabling technologies in digital video broadcasting (DVB) system. The paper presents the current and future operational scenarios for DVB via satellite (DVB-S) system. Review of the current state-of-the-art technologies consisting of integration of(More)
The vesicular monoamine transporter type 2 (VMAT2) packages pre-synaptic monoamines into vesicles. Previously, we generated mice hypomorphic for the VMAT2 gene (Slc18a2), which results in a approximately 95% reduction in VMAT2 protein, disrupted vesicular storage, severe depletion of striatal dopamine and mice with moderate motor behaviour deficits.(More)
This article presents an overview of the DVB-RCS system addressing mobile scenarios (DVB-RCS+M). It analyses the challenges linked to the mobility support and it summarises some of the techniques to cope with those challenges. The focus of this article will be on the technical solutions analysed within the framework of ESA studies and contracts. In(More)
