    We generalize the Maldacena correspondence to the logarithmic conformal field theories. We study the correspondence between field theories in (d + 1)-dimensional AdS space and the d-dimensional logarithmic conformal field theories in the boundary of AdS[sub d+1]. Using this correspondence, we...

    We construct the propagator of the massive tensor field of the second rank on the Euclidean continuation of the anti-de Sitter (AdS) space. We find the explicit expression for the propagator in the limit where the field takes values at the boundary of the AdS space. We show that the limiting...

    The molecular chaperone heat-shock protein 90 (Hsp90) is one of the most abundant proteins in unstressed eukaryotic cells. Its function is dependent on an exceptionally slow ATPase reaction that involves large conformational changes. To observe these conformational changes and to understand...

    Maxwell's and Hertz's pure-field theories, which excluded the convective conception of electric currents and the discreteness of electric particles, are illustrated in the first sections of the paper. Thereafter, I examine Lorentz's theory of electrons and contrast it with Maxwell's and Hertz's...

    Physical experiments often require the generation of a short-lived magnetic field with specified limits of nonuniformity. Various energy storage units, specifically capacitor banks, are used to supply pulsed power to the magnetic system. The simplest configuration of such a magnetic system is...

    A classical pion field that is similar to a disoriented chiral condensate is considered in the presence of an external source. The field is similar to the condensate in that the isotopic orientation of the field in the whole space is determined by a single vector. Within the nonlinear sigma...
