Analytical expressions describing the variability of effective constitutive parameters of non-metallic metamaterials, as a function of the constituent geometric and material parameters and their variations, have been developed from the total differential of Clausius-Mossotti expressions (using Mie dipole polarizabilities) for the effective (bulk) constitutive parameters of the metamaterial. In ...

We define the dielectric constant (susceptibility) that should enter the Maxwell boundary value problem when applied to microscopic dielectric interfaces polarized by external fields. The dielectric constant (susceptibility) of the interface is defined by exact linear-response equations involving correlations of statistically fluctuating interface polarization and the Coulomb interaction energy...

We propose a simple explanation for the constant mean brightness observed between outbursts in dwarf novae. Secular changes in the total energy dissipation rate of the accretion disc brought about by variations in surface density, temperature and disc radius can be regulated by the gradual cooling of a small, critically-stable hot inner region. The hypothesis is supported with two-dimensional t...

We use heavy quark effective theory ~HQET! techniques to parametrize certain nonperturbative effects related to quantum fluctuations that put both heavy quarks and antiquarks in quarkonium almost on shell. The large off-shell momentum contributions are calculated using Coulomb-type states. The almost on-shell momentum contributions are evaluated using an effective ‘‘chiral’’ Lagrangian which in...

background: although giant cell tumor (gct) is considered to be a primary benign bone tumor, its aggressive behavior makes its diagnosis and treatment, difficult and challenging. this is especially true in distal radius where gct appears to be more aggressive and difficult to control locally. we report our clinical outcome of en-block resection and reconstruction with non-vascularized fibular a...

where YO has arbitrary constants for elements. T.he system composed of (1) and (3), if passive, is known to have a unique solution in the set of analytic functions by a general theorem of Konig1 and the linearity of the right members makes possible the immediate extension of this result to the set of once differentiable functions (say, by the method of successive approximations). Recently, Vess...

Using a redshift survey of 1779 galaxies and photometry from the 2-Micron All-Sky Survey (2MASS) covering 200 square degrees, we calculate independent mass and light profiles for the infall region of the Coma cluster of galaxies. The redshift survey is complete to K s = 12.2 (622 galaxies), 1.2 magnitudes fainter than M * Ks at the distance of Coma. We confirm the mass profile obtained by Gelle...
