A new Discontinuous Galerkin Formulation is introduced for the elliptic reactiondiffusion problem that incorporates local second order distributional derivatives. The corresponding bilinear form satisfies both coercivity and continuity properties on the broken Hilbert space of H2 functions. For piecewise polynomial approximations of degree p ≥ 2, optimal uniform h and p convergence rates are ob...

Achieving high valley degeneracy (i.e. "band convergence") in a material usually results considerably enhanced thermoelectric properties. However, it is still unclear why this strategy of designing efficient materials so successful, since the benefit increased density states may be severely degraded by intervalley scattering. Using first-principles calculations, we investigate these effects $p$...

BACKGROUND Convergence spasm refers to transient ocular convergence, miosis and accommodation associated with disconjugate gaze mimicking abducens palsy. While it may be a manifestation of brainstem pathology, this sign is often associated with conversion (somatisation) disorders and, if unrecognised as a sign of a psychogenic disorder, it may lead to unnecessary and occasionally invasive evalu...

OBJECTIVE To compare clinically practiced convergence angle values of tooth preparation with recommended values, and also the effect of tooth position and operator experience on convergence angle. STUDY DESIGN Analytical study. PLACE AND DURATION OF STUDY The study was carried out at the Dental clinic, The Aga Khan University Hospital, Karachi, from January to June 2007. METHODOLOGY A min...
