A maxwellian tetrad theory of gravity with preferred frames: A

A theory of gravity is proposed which seeks to mimic maxwellian electromagnetism whilst maintaining the principle of equivalence. The curls of tetrad potentials are taken as field strengths and Maxwell-like free-field equations are set up which contain a non-linear gravitational current term and which are generally covariant but not locally Lorentz covariant. The weak field approximation is solved for static metrical spherical symmetry and solutions constructed which agree with the GR predictions.     

On the limiting behavior of Burger's equation

The limiting behavior as the viscosity goes to zero of the solution of the first boundary value problem for Burger's equation is considered. The method consists in identifying the solution of Burger's equation with the optimal control of an appropriate stochastic control problem.     

Photoelectron branching ratios and asymmetry parameters of the two outermost molecular orbitals of methyl cyanide

Vibrationally resolved photoelectron branching ratios and asymmetry parameters have been determined for the two outermost molecular orbitals of methyl cyanide. The results are discussed briefly within the context of similar studies on cyanogen and hydrogen cyanide, and in relation to structures exhibited in the photoionization efficiency curve.     

Elimination of negative probabilities within the causal stochastic interpretation of quantum mechanics

Negative probabilities resulting from the Klein-Gordon equation are eliminated from quantum theory within the stochastic interpretation of quantum theory (SIQM) for spin-zero particles. The assumption of real physical paths in E₄ implies that only particles (antiparticles) of positive energies move forward in time with positive probability densities.
