MULTIPLE SOLUTIONS FOR THE MEAN CURVATURE EQUATION

, 2015
Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)We perturb the mean curvature operator and find multiple critical points of functionals that are not even As a consequence we find infinitely many solutions for a quasilinear elliptic ...

A numerical scheme for the curvature equation near the singularities

, 2005
In this paper we propose a modification in the usual numerical method for computing the solutions of the curvature equation in the plane . This modification takes place near the singularities of the image.

Dirac‐Source Linear X‐Ray Detection Diode

Advanced Functional Materials, EarlyView.
Monolayer graphene imparts near linear current‐voltage behavior to a perovskite X‐ray detection diode, contrasting with conventional diode‐like responses. Exploiting graphene's Dirac dispersion and a Schottky‐like back‐to‐back junction, the device achieves six‐orders‐of‐magnitude dark current suppression while retaining linearity over 200 V, enabling ...

Second-order boundary estimates for solutions to singular elliptic equations

Electronic Journal of Differential Equations, 2009
Let $Omegasubset R^N$ be a bounded smooth domain. We investigate the effect of the mean curvature of the boundary $partialOmega$ in the behaviour of the solution to the homogeneous Dirichlet boundary value problem for the singular semilinear equation

Nanoconfinement‐Induced Second‐Harmonic Circular Dichroism via Chirality–Ferroelectric Coupling

Advanced Functional Materials, EarlyView.
Nanoconfinement of a ferroelectric nematic liquid crystal within a chiral nanoporous sponge yields an enhanced second‐harmonic generation circular dichroism (|gSHG–CD| ≈ 1.1). Polarization‐resolved analysis suggests an additional magnetic‐dipole‐associated nonlinear contribution under nanoconfinement, highlighting chirality–ferroelectric coupling as a ...

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

Minimal hypersurfaces with zero Gauss-Kronecker curvature

, 2005
We investigate complete minimal hypersurfaces in the Euclidean space R-4, with Gauss-Kronecker curvature identically zero. We prove that, if f : M-3 -> R-4 is a complete minimal hypersurface with Gauss-Kronecker curvature identically zero, nowhere ...

Second-order boundary estimates for solutions to singular elliptic equations in borderline cases

Electronic Journal of Differential Equations, 2011
Let $Omegasubset R^N$ be a bounded smooth domain. We investigate the effect of the mean curvature of the boundary $partialOmega$ on the behaviour of the solution to the homogeneous Dirichlet boundary value problem for the equation $Delta u+f(u)=0 ...
