Quantum Mechanical Carrier of the Imprints of Gravitation [PDF]
, 1998 We exhibit a purely quantum mechanical carrier of the imprints of gravitation by identifying for a relativistic system a property which (i) is independent of its mass and (ii) expresses the Poincare invariance of spacetime in the absence of gravitation ...

Universe, 2019 We report on the behavior of two-level quantum systems, or qubits, in the background of rotating and non-rotating metrics and provide a method to derive the related spin currents and motions. The calculations are performed in the external field approximation.

The Effect of the Gravitation of the Moon on Frequency of Births
Environmental Health Insights, 2010 The purpose of this study was to examine the influence of the gravitation of the Moon on the frequency of births in Kyoto, Japan. A retrospective cohort analysis of 1007 consecutive births without the use of the induction agents was conducted on a ...

Radar time delays in the dynamic theory of gravity [PDF]
Serbian Astronomical Journal, 2004 There is a new theory gravity called the dynamic theory, which is derived from thermodynamic principles in a five dimensional space, radar signals traveling times and delays are calculated for the major planets in the solar system, and compared to those ...

Motion of a rigid dumbbell with a flywheel in a central gravitational field
RUDN Journal of Engineering Research, 2022 The article introduces theoretical studies of space flight of the dumbbell. A description of the general qualitative picture of the possibility of implementing the non-reactive principle of motion of an extended body in a central gravitational field is ...

Gravitational and Anti-Gravitational Applications
International Journal of Geosciences, 2017 It is now possible to partially deflect gravitation away from an object so that the gravitational attraction on the object is reduced. That effect makes it possible to extract energy from the gravitational field, which makes the generation of gravito-electric power technologically feasible.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma
Molecular Oncology, EarlyView.Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

General relativistic theory of gravity and electricity
Revista de Investigación de Física, 2022 As gravitation and electromagnetism are closely analogous long-range interactions, and the current formulation of gravitation is given in terms of geometry, we expect the latter also to appear throug the geometry.
