THE ROLE OF MACROSCOPIC TURBULENT DIAMAGNETISM IN ENSURING LONG-TERM STABILITY OF SUNSPOTS
Odessa Astronomical Publications, 2020 We investigated the role of macroscopic turbulent diamagnetism in ensuring the long-term stability of the equilibrium state of the sunspots. The physical meaning of macroscopic diamagnetism of turbulent plasma is expulsion of a large-scale magnetic field

Nonlinear Robin problems with unilateral constraints and dependence on the gradient
Electronic Journal of Differential Equations, 2018 We consider a nonlinear Robin problem driven by the p-Laplacian, with unilateral constraints and a reaction term depending also on the gradient (convection term). Using a topological approach based on fixed point theory (the Leray-Schauder alternative

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler
Advanced Materials, EarlyView.An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

A remark on ground state solutions for Lane-Emden-Fowler equations with a convection term
Electronic Journal of Differential Equations, 2007 Via a sub-supersolution method and a perturbation argument, we study the Lane-Emden-Fowler equation $$ -Delta u =p(x)[g(u)+f(u)+| abla u|^q] $$ in $mathbb{R} ^N$ ($Ngeq3$), where ...

Existence results for Robin problems involving p(x)-Laplacian-like operators with convection term
Demonstratio MathematicaThis paper studies the existence of solutions for Robin problems involving p(x)-Laplacian-like operators which arise from capillarity phenomena. When we only consider the convective term, due to the lack of a variational structure, the well-known ...

Singular quasilinear elliptic problems with convection terms
AIP Conference Proceedings, 2022 In this paper we present some very recent results regarding existence, uniqueness, and multiplicity of solutions for quasilinear elliptic equations and systems, exhibiting both singular and convective reaction terms. The importance of boundary conditions (Dirichlet, Neumann, or Robin) is also discussed.
