    ABSTRACT: Summary form only given. In the past, we have endeavored to develop a better understanding of the nature of fuzzy-logic approaches on the basis of their relation to other fundamental scientific notions. While many of these efforts evolved in the context of specific applications, their ultimate motivation was the enhancement of basic understanding-particularly in the area of the relations between various approximate-reasoning methodologies. In this presentation we review applied methods stemming from these foundations-relating fuzzy-logic concepts to notions of utility, cost, and similarity-emphasizing the need for the understanding of basic conceptual structures in the development of effective approaches to treat a wide variety of problems. We will review recent applications of approaches based on this view of fuzzy logic to three major Intelligent-system development problems: distributed robotics, qualitative description of complex objects, and knowledge discovery and retrieval in very large databases. We will present major technical issues arising in the consideration of these problems while addressing also fundamental questions of essential importance to the development and understanding of applicable approaches. In particular, we will consider matters related to the notions of team and individual goals, negotiation, and agent-based preferences in the context of distributed robotics; the concepts of cluster and clustering in the context of data analysis and understanding; and the relations between knowledge-based structures, such as ontologies and know ledge-bases, and similarity measures in the context of information-retrieval problems.

    ABSTRACT: In response to growing U.S. interest, the Society for Coronary Angiography and Interventions recently formed a Transradial Committee whose purpose is to examine the utility, utilization, and training considerations related to transradial access for percutaneous coronary and peripheral procedures. With international partnership, the committee has composed a comprehensive overview of this subject presented here-with.

    ABSTRACT: Randomized trials have shown that transradial approach, compared with transfemoral, reduces vascular complications (VCs) of coronary procedures in selected patients. Yet, radial approach is associated to a variety of access-site VC as well as to a higher failure rate compared with femoral access. At our institution, from May 2005 to May 2010, we prospectively assessed the occurrence and outcome of VC in consecutive patients undergoing transradial percutaneous coronary procedures performed by trained radial operators. The need of access crossover to complete the procedure was also prospectively investigated. Vascular complications were classified as "radial related" or "nonradial related" (in the case of access crossover). Vascular complications were also classified "major" if requiring surgery and/or blood transfusions or causing hemoglobin drop >3 g/dL. Ten thousand six hundred seventy-six procedures were performed using a right radial (87.5%), left radial (12.4%), or ulnar (0.1%) artery as primary access. A total of 53 VCs (0.5%) were observed: 44 (83%) radial related and 9 (17%) nonradial related. Major VCs occurred in 16 patients only (0.2%) and were radial related in 10 (62.5%) and nonradial related in 6 (37.5%) patients. Vascular complications rate was stable during the study and independent of operator's experience. Access crossover rate was 4.9%, differed according to the operator radial experience and significantly decreased over time. The present study, conducted in a center with high volume of radial procedures, shows that transradial approach is associated with a very low rate of VC, which is stable over time. On the contrary, access crossover rate decreased over time and differed according to operator (radial) experience.
