    Notizen: Abstract We consider a variational procedure for approximating the solution of the state regulator problem with time delay. Motivated by a dual formulation of the problem, we introduce a positive-definite functionalF over a certain energy space of Mikhlin and obtain approximating solutions by the Ritz-Trefftz idea of minimizing it over finite-dimensional subspaces. The resulting approximating solutions, in turn, furnish suboptimal solutions which converge to the optimal solution of the regulator problem with time delay. A priori error bounds in terms of splines are given. A posteriori error bounds are also obtained.

    Notizen: Abstract Pontryagin's minimum principle for nonlinear differential systems with Stieltjes boundary constraints and performance index with an integral of the Lebesgue-Stieltjes type is derived. The case of infinite time is also considered.

    Thema: Mathematik
    Notizen: Abstract In this article, we consider max-min controllability in linear pursuit games with norm-bounded controls. Our approach is based on the separation theorem of disjoint compact convex sets in Euclidean space. Necessary and sufficient conditions for max-min controllability are given in terms of an explicit relative controllability expression which, in a sense, is a comparison between the control capabilities of the competing parties. Minimal time and optimal norm problems are investigated.

    Thema: Medizin
    Notizen: Summary Hybridomas secreting monoclonal antibodies against herpes simplex virus (HSV) DNA binding proteins (DBP) have been produced. Five HSV DBP have been characterized according to molecular weight, affinity for DNA, kinetic class and localization within the infected cell. By preparing an immunoadsorbent column from antibody TI8, its specific DBP was purified to apparent homogeneity. The purified DBP retained the ability to bind to DNA.
