Uniqueness and stability of solutions without the boundary condition
Boundary Value Problems, 2019 A parabolic equation related to the p-Laplacian is considered. If the equation is degenerate on the boundary, then demonstrating the regularity on the boundary is difficult, the trace on the boundary cannot be defined, in general.

Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, EarlyView.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States
Advanced Optical Materials, EarlyView.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‐

Host Tuned Luminescence Lifetime Thermometers for Imaging Boiling Thermal Dynamics Through Bubbles
Advanced Optical Materials, EarlyView.The bismuth to vanadate distance is adjusted in solid solutions of ytrrium and scandium orthovanadate to design a lifetime‐based luminescence thermometer with optimal temperature resolution at 100 °C. It is applied on the surface of a boiling channel to observe the thermal signatures of bubble growth and liquid film dry‐out.

Approximate solution to a hybrid model with stochastic volatility: a singular-perturbation strategy [PDF]
, 2009 We study a hybrid model of Schobel-Zhu-Hull-White-type from a singular-perturbation-analysis perspective. The merit of the paper is twofold: On one hand, we find boundary conditions for the deterministic non-linear degenerate parabolic partial ...

On the parabolic potentials in degenerate‐type heat equation [PDF]
International Journal of Stochastic Analysis, 1991 Using distributions theory technique we introduce parabolic potentials for the heat equation with one time‐dependent coefficient (not everywhere positive and continuous) at the highest space‐derivative, discuss their properties, and apply obtained results to three illustrative problems.

Advanced Optical Materials, EarlyView.A flexible metallic metasurface sticker is placed on a dielectric metasurface to study interlayer optical coupling. A bright quadrupolar surface lattice resonance in the top layer and a dark quadrupole mode in the bottom layer hybridize into symmetric and antisymmetric modes.
