Volume: Menegatti E.; Wright M.; Pagello E. Pages: Menegatti||Wright||Pagello-In this paper we propose a new sensor for the Spatial Semantic Hierarchy created by Benjamin Kuipers. To prove the effectiveness of this new sensor it has been used as a sole sensor for a robot. The task of the robot is to build a topological map of an unknown environment using the Spatial Semantic Hierarchy. In the paper, we present the strict link that it is possible to create between the Spatial Semantic Hierarchy and the omnidirectional images. We propose a set of topological events, that it is possible to identify in the sequence of images acquired while the robot moves. These topological events can be used to pose a discrete set of places that will be the nodes of the topological map. The results of simulated experiments, and the experiments we carried out with a real robot, shows the feasibility of this approach. At the moment we are testing a new multi-part mirror expressively designed for this application.

Volume: Menegatti E.; Nori F.; Pagello E.; Pellizzari C.; Spagnoli D. Pages: Menegatti||Nori||Pagello||Pellizzari||Spagnoli-The aim of this paper is to provide a guideline for the design of an omnidirectional vision system for the Robocup domain. We report the design steps undertaken, with a detailed description of the design of an omnidirectional mirror with a custom profile. In the second part, we present the software written to exploit the properties of the designed mirror. The application for which the vision system is designed is the Middle-Size Robocup Championship. The task performed by the vision system is to localise the robot and to locate the ball and other robots in the field of play. Several practical tricks and suggestions are provided. © 2002 Springer-Verlag Berlin Heidelberg.

Volume: Menegatti E.; Pagello E.; Wright M. Pages: Menegatti||Pagello||Wright-This paper reports the new steps undertaken in our work aimed to demonstrate the effectiveness of an omnidirectional vision sensor when conjugated with the Spatial Semantic Hierarchy. The Spatial Semantic Hierarchy was proposed by Benjamin Kuipers as a method for map building with robots. In our work, a robot builds a topological map of an unknown environment, using the Spatial Semantic Hierarchy and an omnidirectional vision system as the only sensor. In the paper, we present the new omnidirectional mirror and the new robot. The new mirror was expressly designed for this application, the robot's chassis was designed to create a synergy with the omni-directional vision sensor. A complete description of our project is reported, underlying the strict link it is possible to create between omnidirectional vision and the Spatial Semantic Hierarchy. Experiments in simulated environments and in real environments produced positive results.

These effects of Tat are attributed to the induction of bcl-2 gene expression. In this study we show that the blocking of both intracellular and extracellular Tat correlates with a decrease of bcl-2 transcripts, leading in vitro to a lower growth rate and attenuation of the transformed phenotype and in vivo to a reduced angiogenic and oncogenic activity of Tat-expressing cells. These results support the notion that bcl-2 is an effector of Tat-induced angiogenesis and oncogenesis and indicate that the blocking of Tat functions by immunoprophylactic, pharmacological, and gene therapy approaches may help to control oncogenesis during AIDS. © 2002 Elsevier Science (USA).
