Simulations show a path to 'ideal glass' with crystal-like entropy

The types of glass that we encounter in everyday life, such as window glass or smartphone screens, are disordered solids. This means that they consist of particles locked in place, like those in ...

40,000-year-old Paleolithic carvings may be the precursor to human writing

Rows of tiny crosses and dots run along the flank of a mammoth no bigger than your palm. Someone carved it from a tusk around ...

From theory to safety: New model predicts how combustion scenarios unfold

Researchers from Skoltech have published a paper in the journal Physica D: Nonlinear Phenomena presenting an analysis of steady propagating combustion waves—from slow flames to supersonic detonation ...

Structure-preserving neural networks for the regularized entropy-based closure of a linear, kinetic, radiative transport equa...

The main challenge of large-scale numerical simulation of radiation transport is the high memory and computation time requirements of discretization methods for kinetic equations. In this work, we ...

A unified regularization theory: the maximum non-extensive entropy principle

Tsallis' non-extensive entropy is used as a regularization operator. The parameter ''q'' (non-extensivity parameter) has a central role in the Tsallis' thermostatiscs formalism. Here, several values ...
