Natural killer cell stimulatory factor (NKSF), or interleukin 12 (IL-12), is a 70-kD heterodimeric cytokine composed of two covalently linked chains, p40 and p35. NKSF/IL-12 has multiple effects on T and NK cells and was originally identified and purified from the supernatant fluid of Epstein-Barr virus (EBV)-transformed human B lymphoblastoid cell lines.(More)
| Research work reported in the present paper concerns the development of a navigation system for a mobile robot designed to accomplish missions inside the building of big organizations, such as hospitals or malls. Useful terminology is rst introduced, and a rather detailed presentation of architecture and overall functioning of the system follows(More)
Real-world applications of pattern recognition, or machine learning algorithms, often present situations where the data are partly missing, corrupted by noise, or otherwise incomplete. In spite of that, developments in the machine learning community in the last decade have mostly focused on mathematical analysis of learning machines, making it difficult for(More)
Low-cost, purely visual modules are presented, which are able to reliably perform real-time computation of kinematic quantities relevant for the navigation of commercial vehicles moving along highways or motorways. Taking as input a video stream of b/w images coming from a standard camera mounted aboard the vehicle, the modules return instantaneous(More)
To understand how expression of IL-8 mRNA is regulated, we studied the effects of Staurosporine, H7, phorbol-myristate-acetate and Dexamethasone in human neutrophils subsequently treated with IFN-gamma. Our results can be summarized as follows: a) IL-8 mRNA steady state levels were enhanced in a dose dependent fashion by both Staurosporine and(More)
A system capable of processing visual information in real-time is a common need for many arti cial vision tasks. Biological vision systems are highly interconnected systems, but it is reasonable to assume that low-level vision operations could be described in terms of independent ltering operations, such as direction detection, disparity and velocity(More)
