In this paper we report on a successful tele-teaching project between the Computer Science Department of the Technische Universität Dresden (Germany) and of the Universidade Nova de Lisboa (Portugal).

By a significant modification of the standard protocol of quantum state teleportation, two processes "forbidden" by quantum mechanics in their exact form, the universal NOT gate and the universal optimal quantum cloning machine, have been implemented contextually and optimally by a fully linear method. In particular, the first experimental demonstration of the tele-UNOT gate, a novel quantum in...

DNA amplification at 17q is frequently detected in upper gastrointestinal adenocarcinomas (UGC; stomach and esophagus). In this study, we did fluorescence in situ hybridization on a tissue microarray that contained 304 UGCs and 89 normal stomach samples using a approximately 168-kb BAC clone (CTD-2019C10) that maps to 17q12-q21.1. This 168-kb region contains the following genes: PPP1R1B/DARPP-3...

Integration of Television with Internet technologies has renewed the discussion for a new era of political communication. The adoption of Internet communication rules in television, has introduced a new hybrid model of “Internetized Television”. This hybrid model aims to reverse the passiveness of tele-democracy, supporting a more active political participation of citizens. However, since now, ...

This paper presents a system developed with off-the shelf components which will be used to study humanrobot cooperative tasks from tele-manipulation to supervisory control. The approach enables the design to be modular and flexible, thus presenting an upgradable laboratory and test bed for prototyping autonomy-enhanced and supervised-control activities for Space-Analogue Mobile Manipulation.
