Folding of set-theoretical solutions of the Yang-Baxter equation
We establish a correspondence between the invariant subsets of a non-degenerate symmetric set-theoretical solution of the quantum Yang-Baxter equation and the parabolic subgroups of its structure group, equipped with its canonical Garside structure ...

Applications of QSPR and Machine Learning in Molecular Photonics
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

Viscosity solutions to degenerate diffusion problems
This paper concerns the weak solutions to a Cauchy problem in $R^N$ for a degenerate nonlinear parabolic equation. We obtain the Holder regularity of the weak solutions to this problem.

Nonlinear Transmission of Strong THz‐Electric Fields Through Thin Gold Films
Gold is is the prime metal for imaging THz radiation. This study demonstrates that the interaction of strong THz pulses with gold becomes nonlinear at certain peak THz‐electric field strengths. The strong fields change the electron density of states which contributing to the absorption of the propagating THz pulse.

Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States
A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐

Existence and continuity of global attractors for a degenerate semilinear parabolic equation
In this article, we study the existence and the upper semicontinuity with respect to the nonlinearity and the shape of the domain of global attractors for a semilinear degenerate parabolic equation involving the Grushin operator.

ON AN OPTIMAL STARTING CONTROL PROBLEM FOR DEGENERATE PARABOLIC EQUATION
An optimal control problem for degenerate parabolic equation with mixed boundary conditions are considered. Having applied the Hardy - Poincare inequality, it is shown that this problem has a unique optimal solution in the correspondence weighted Sobolev
