The spontaneous breaking of local Lorentz invariance in the early Universe, associated with a first order phase transition at a critical time tc, generates a large increase in the speed of light andâ€¦ (More)

A dynamical model for varying light velocity in cosmology is developed, based on the idea that there are two metrics in spacetime. One metric gÎ¼Î½ describes the standard gravitational vacuum, and theâ€¦ (More)

A fully relativistic modified gravitational theory including a fifth force skew symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distanceâ€¦ (More)

A covariant scalar-tensor-vector gravity theory is developed which allows the gravitational constant G, a vector field coupling Ï‰ and the vector field mass Âµ to vary with space and time. Theâ€¦ (More)

A gravity theory is developed with the metricË†g ÂµÎ½ = g ÂµÎ½ +Bâˆ‚ Âµ Ï†âˆ‚ Î½ Ï†. In the present universe the additional contribution from the scalar field in the metricË†g ÂµÎ½ can generate an acceleration inâ€¦ (More)

The dynamical consequences of a bimetric scalar-tensor theory of gravity with a dy-namical light speed are investigated in a cosmological setting. The model consists of a minimally-coupledâ€¦ (More)

The RAS/RAF/MEK pathway is activated in more than 30% of human cancers, most commonly via mutation in the K-ras oncogene and also via mutations in BRAF. Several allosteric mitogen-activatedâ€¦ (More)

A new version of nonsymmetric gravitational theory is presented. The field equations are expanded about the Minkowski metric, giving in lowest order the linear Einstein field equations and massiveâ€¦ (More)

A vector-tensor theory of gravity that was introduced in an earlier publication is analyzed in detail and its consequences for early universe cosmology are examined. The multiple light cone structureâ€¦ (More)
