Modified gravity

In this paper, we made the first attempt to analyze the impact of tariffs on Vietnam’s export of Mach and Elec products to partners within CPTPP. This study utilized a modified gravity model and simultaneous quantile regression to analyze Vietnam’s export turnover of machinery and electronic products to 10 CPTPP member countries from 2005 to 2020 on different quantiles of the export distribution.

The present study showed that gravity stress changed ginger-induced effects on phasic ileal motility in the male, but not in the female, indicating that sex differences were observed in the ginger effects modulated by stress loading.

Searching for the origin of the dark matter and the dark energy is among the problems that the modern physics, including the general theory of relativity, is facing to. Various theories or models have been proposed to solve these problems without satisfactory success yet.

The functional integral method can be used in quantum mechanics to find the scattering amplitude for particles in the external field. We obtained the potential scattering amplitude from the complete Green function in the corresponding external field through solving the Schrodinger equation, after being separated from the poles on the mass shell, which takes the form of an eikonal (Glauber) representation in the high energy region and the small scattering angles.

In the linearized gravitational theory, we follow up the lead to eikonal amplitude for two scalar particles at high energies with fixed momentum transfers based on quasi-potential equation in the framework of the modified perturbation theory.

A procedure of testing the f(R)-theory of gravity is discussed. The latter is an extension of the general theory of relativity (GR). In order this extended theory (in some variant) to be really confirmed as a more precise theory it must be tested. To do that we first have to solve an equation generalizing Einstein’s equation in the GR.
