The theory of the dynamic medium reference (DMR) has already been presented in several articles by this author [O. Pignard, Phys. Essays 32 , 422 (2019); 33 395 (2020); 34 61 (2021)], and particular, first one titled “Dynamic reference: A new gravitation.” This proposes existence a made up entities called gravitons. gravitational field is flux medium, whose speed defined formula <mml:math di...

Gravitational microlensing has become a mature technique for discovering small gravitational lenses in the Universe which are otherwise beyond our detection limits. Similarly, plasma can help us explore cosmic lenses. Both pulsar scintillation and extreme scattering events of compact radio sources suggest existence $\sim$ AU scale ionized interstellar medium (IISM), whose astrophysical correspo...

The growth dynamics of polyacrylamide hydrogel beads due to liquid absorption under geometric confinement is studied. First, the behavior individual investigated and, subsequently, analyzed in presence several interacting same material. In both, and collective studies, magnitude varied, order investigate effect that stress applied on particles has their hydration kinetics.
