Varying speed of light cosmology from a stringy short distance cutoff [PDF]
, 2001 It is shown that varying speed of light cosmology follows from a string-inspired minimal length uncertainty relation. Due to the reduction of the available phase space volume per quantum mode at short wavelengths, the equation of state of ...

Eddy genesis and transformation of Stokes flow in a double-lid-driven cavity. Part 2: deep cavities [PDF]
, 2006 This paper extends an earlier work [1] on the development of eddies in rectangular cavities driven by two moving lids. The streamfunction describing Stokes flow in such cavities is expressed as a series of Papkovich-Faddle eigenfunctions.

Consequences of Neutrino Lorentz Violation For Leptonic Meson Decays [PDF]
, 2011 If the observation by OPERA of apparently superluminal neutrinos is correct, the Lagrangian for second-generation leptons must break Lorentz invariance. We calculate the effects of an energy-independent change in the neutrino speed on another observable,
