Stars creating a gravitational repulsion

, 2018
In the framework of the Theory of General Relativity, models of stars with an unusual equation of state $\rho c^20$ where $\rho$ is the mass density and $P$ is the pressure, are constructed.

Center of pressure based segment inertial parameters validation

PLOS ONE, 2017
By proposing efficient methods for estimating Body Segment Inertial Parameters' (BSIP) estimation and validating them with a force plate, it is possible to improve the inverse dynamic computations that are necessary in multiple research areas. Until today a variety of studies have been conducted to improve BSIP estimation but to our knowledge a real ...

Cosmic censorship and spherical gravitational collapse with tangential pressure [PDF]

, 1997
We study the spherical gravitational collapse of a compact object under the approximation that the radial pressure is identically zero, and the tangential pressure is related to the density by a linear equation of state.

Toughening of silicon nitride ceramics through stress-induced phase transformation

Journal of Advanced Ceramics
Ceramics, particularly covalently bonded ceramics, exhibit intrinsic brittleness resulting from the strong directional nature of their chemical bonds, significantly limiting their applications.

Synthesis of quenchable amorphous diamond

Nature Communications, 2017
Diamond’s properties are dictated by its crystalline, fully tetrahedrally bonded structure. Here authors synthesize a bulk sp 3-bonded amorphous form of carbon under high pressure and temperature, show that it has bulk modulus comparable to crystalline ...
