the days of Abraham (1903) and Lorentz (1904), who derived for the first time the radiation reaction force on an extended electron 1. Assuming that the electron has a spherically symmetric rigid charge distribution of radius r0 in its

imply an informational cost (distorted pricing and/or equilibrium-path price wars), since a higher-cost ¯rm must be deterred from mimicking a lower-cost firm by charging a lower price. A rigid-pricing scheme, where a firm's collusive price is independent of its current cost position, sacrifices

We prove global existence and uniqueness of classical solutions for the Maxwell-Lorentz system of a nonrotating rigid charge distribution, i.e. the relativistic dynamics of a nonrotating extended electron, which is subject to its own electromagnetic fields and an external potential. Local existence

Abstract In this paper we investigate the m s p o r t proses for rigid spherically symmetric macromolecules, having a segment densiry distribution falling off as rrA. We calculate the rotational and translational diffusion coefficient for P spbaically symmetric polymer and the shear viscosiiy for a

Generality is achieved by weighting volume elements using a spline symmetric to that by which particle charge and cur-rent are weighted to the mesh. The method presented has a number of desirable properties, including conservation

symmetry breaking rely on the assumption that parton distributions are charge symmetric; it is conceivable that current tests of flavor symmetry could be affected by substantial charge symmetry violation. Since all phenomenological parton distributions assume the validity of charge symmetry, in this paper

rigid biopolymers have been recently used as experimental systems for polyelectrolyte electrostatics. Due to their large persistence lengths (Nμm), they can be thought of as idealized charged rods, and are well-suited for comparison with theory. For example, the addition of divalent cations to a

The components of the momentum density are also calculated and used to evaluate the angular momentum distribution. We found no angular

We report a measurement of the inclusive charged-particle distribution for gluon jets derived from nearly S-fold symmetric S-jet events taken at center of mass energy of 29 GeV in e+e- annihilation. The charged-particle spectrum for these jets is observed to fall off more rapidly than those
