## Abstract We study intrinsic biharmonic maps on a fourβdimensional domain into a smooth, compact Riemannian manifold. We prove a partial regularity result without the assumption that the second derivatives are squareβintegrable. Β© 2005 Wiley Periodicals, Inc.
The particle number N fluctuates in a spherical volume fragment of a uniform electron gas. In an ideal classical-gas or "Hartree" model, the fluctuation is strong, with ( N ) 2 = N . We show in detail how this fluctuation is reduced by exchange in the ideal Fermi gas and further reduced by Coulomb c
In this paper, quasi-brittle fracture along Γ°1 0 0Γ plane in three dimensions was obtained with successive over relaxation numerical simulation and elastic network model (B6:14 Γ 10 6 atoms) for BCC metals in fracture Mode I. The material-dependent parameter, G 0 =G; was introduced in this simulatio
