    Notes: Abstract. This paper considers the following problem, which we call the largest common point set problem (LCP): given two point sets P and Q in the Euclidean plane, find a subset of P with the maximum cardinality that is congruent to some subset of Q . We introduce a combinatorial-geometric quantity λ(P, Q) , which we call the inner product of the distance-multiplicity vectors of P and Q , show its relevance to the complexity of various algorithms for LCP, and give a nontrivial upper bound on λ(P, Q) . We generalize this notion to higher dimensions, give some upper bounds on the quantity, and apply them to algorithms for LCP in higher dimensions. Along the way, we prove a new upper bound on the number of congruent triangles in a point set in four-dimensional space.

    Notes: Abstract We have employed alpha-interferon (IFN-α), an anti-viral agent, in the treatment of severe idiopathic sudden sensorineural hearing loss (ISSHL). Forty-two patients were studied and had an average hearing ability of ≥ 70 dB before treatment. We also examined 2′-5′ oligoadenylate synthetase (2,5A-S) activity, one of the parameters indicating anti-viral activity of IFN, to investigate the relationship between the suppression of viral proliferation and prognosis and explain the pathogenesis of ISSHL. Complete recovery was found in 27 patients (64.3%) after IFN therapy. Increased 2,5A-S activity was observed on the 3rd day of IFN therapy in 24 of the 27 patients who completely recovered. No severe adverse events were reported after IFN therapy. Findings suggest that IFN therapy may be effective and safe in the treatment of ISSHL and calls for further investigation.

    An approach to the emergent design theory and applications (1999)
    Springer
    Artificial life and robotics 3 (1999), S. 86-89 
    Details
    ISSN: 1614-7456
    Keywords: System design ; Emergence ; Evolutionary computation ; Passive filter ; Multi-link robot

    Notes: Abstract An emergent approach for the design of artifacts (artificial systems) is proposed. First, the system design process is reformulated in the framework of set and mapping theory, and the design problem is defined as an inverse mapping from the set of specifications depending on the environment to the set of components and their connections. The inverse problem can be solved by the iteration of forward mapping. Next, the problem is classified from the viewpoint of the specifications and the environment. The concepts of evolution, adaptation, learning, and coordination can be related to classified problems. Emergent design procedure is defined in the framework of these concepts, in particular by taking evolutionary computing techniques into account. Two examples are shown: the first is a design of complex linear passive filters, and the other is a design of multilink moving robots.
