Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023 We introduce a computer algorithm that incorporates the experience of battery researchers to extract information from experimental data reproducibly. This enables the fitting of complex models that take up to a few minutes to simulate. For validation, we process full‐cell GITT measurements to characterize the diffusivities of both electrodes non ...

Advanced Optical Materials, EarlyView.Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

Carleman estimates, observability inequalities and null controllability for interior degenerate non smooth parabolic equations [PDF]
arXiv, 2015 We show Carleman estimates, observability inequalities and null controllability results for parabolic equations with non smooth coefficients degenerating at an interior point.

Advanced Photonics Research, EarlyView.The strong coupling is investigated as an effective method to modulate the second‐harmonic generation (SHG) in the defect mode and Tamm plasmon resonances. Throughout the entire anticrossing Rabi splitting process induced by strong coupling, the difference in SHG efficiency between two resonances can be modulated by up to two orders of magnitude ...

Radial symmetric solutions of the Cahn-Hilliard equation with degenerate mobility
Electronic Journal of Qualitative Theory of Differential Equations, 2001 In this paper we study the radial symmetric solutions of the two-dimensional Cahn-Hilliard equation with degenerate mobility. We adopt the method of parabolic regularization.

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces
Advanced Photonics Research, EarlyView.The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...

Viscosity solutions to degenerate diffusion problems
Electronic Journal of Differential Equations, 2007 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.

Regularity Results for a class of Semilinear Parabolic Degenerate Equations and Applications [PDF]
Quaderno-IAC (2001), 2001 We consider a possibly strongly degenerate parabolic semilinear problem which can be applied to a differential model for pricing financial derivatives. We prove the asked regularity for applying the Ito's formula which is used for building the differential model.

PULLBACK ATTRACTORS FOR A NON-AUTONOMOUS SEMI-LINEAR DEGENERATE PARABOLIC EQUATION
Glasgow Mathematical Journal, 2010 In this paper, using the asymptotic a priori estimate method, we prove the existence of pullback attractors for a non-autonomous semi-linear degenerate parabolic equation in an arbitrary domain, without restriction on the growth order of the polynomial ...
