Gravity Equation and Trade Agreements: A Different Econometric Approach [PDF]
This paper is aimed at multiplicatively estimating the parameters of the gravity equation by using the Poisson Pseudo-Maximum-Likelihood (PPML) estimator, and taking heteroskedasticity into account at the same time.

Thermo-visco-elastic Rayleigh waves under the influence of couple-stress and gravity
International Journal of Mathematics and Mathematical Sciences, 1991 This paper is concerned with thermo-visco-elastic Rayleigh waves under the influence of couple-stresses and gravity. A more general phase velocity equation for these waves is derived.

The Quantization of Gravity: The Quantization of the Full Einstein Equations
Symmetry, 2023 We quantized the full Einstein equations in a globally hyperbolic spacetime N=Nn+1, n≥3, and found solutions of the resulting hyperbolic equation in a fiber bundle E which can be expressed as a product of spatial eigenfunctions (eigendistributions) and temporal eigenfunctions.
