...Abstract. The total energy E of a star as a function of its angular momentum J and mass M in the Newtonian theory: E = E(J,M) [in general relativity, the gravitational mass M of a star as a function of its angular momentum J and rest mass m, M = M(J,m)], is used to determine the remaining parameters (angular velocity, equatorial radius, chemical potential, etc.) in the case of rigid rotation...

BACKGROUND This article reports outcome in osteotomy for malunion of distal radius fractures. MATERIAL AND METHODS We evaluated 12 patients with distal radius malunion (mean age 54), who were treated with corrective osteotomy. Wrist motion and grip strength were evaluated, along with examination of pre and post osteotomy radiographs. The indications for corrections were degree of deformity, l...

In this paper we show that there is a Lipatov bound for the radius of convergence for superficially divergent one-particle irreducible Green functions in a renormalizable quantum field theory if there is such a bound for the superficially convergent ones. The radius of convergence turns out to be min{ρ, 1/b1}, where ρ is the bound on the convergent ones, the instanton radius, and b1 the first c...

BACKGROUND AND PURPOSE New implant designs have incorporated a single radius instead of a multiple radius to the femoral component in order to improve the mechanical function after TKA. We investigated the amount of quadriceps force required to extend the knee during an isokinetic extension cycle of different total knee designs, focusing on the radius of the femoral component (single vs. multip...

Since the eigenvalue problem of real supersymmetric tensors was proposed, there have been many results regarding numerical algorithms for computing spectral radius nonnegative tensors, among which NQZ method is most studied. However, only suitable calculating a special weakly primitive tensor, or irreducible tensor that satisfies certain conditions. In this paper, by means diagonal similarrity ...

A dynamical symmetry for spherical collapse has been studied using a linear transformation of the initial data set (mass and kinetic energy function) and the area radius. With proper choice of the initial area radius, the evolution as well as the physical parameters namely energy density and shear remain invariant both initially and at any time instant. Finally, it is found that the final outco...

We study the effect of tunneling on the electronic structure of two vertically coupled quantum rings within the spin density functional theory. The ground state configurations of the coupled rings are obtained for a system with 10 electrons as a function of the ring radius and the inter-ring distance. For small ring radius, our results recover those of coupled quantum dots. For large ring radiu...
