Elliptic Yang–Mills equation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
We discuss some recent progress on the regularity theory of the elliptic Yang–Mills equation. We start with some basic properties of the elliptic Yang–Mills equation, such as Coulomb gauges, monotonicity, and curvature estimates. Next we discuss singularity of stationary Yang–Mills connections and compactness theorems on Yang–Mills ...

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...

Optimal Control of Semilinear Elliptic Equations in Measure Spaces

open access: yesSIAM Journal of Control and Optimization, 2014
Optimal control problems in measure spaces governed by semilinear elliptic equations are considered. First order optimality conditions are derived and structural properties of their solutions, in particular sparsity, are discussed.

Magnetic Unclonable Functions Leveraging Remanence and Anhysteretic States

open access: yesAdvanced Functional Materials, EarlyView.
A micrometric array of magnetic pillars provides a stable and unclonable hardware for generating cryptographic keys. From a single device, the ability is demonstrated to produce a 470‐bit key while also offering a reconfigurable mode of operation.

Oscillation for quasilinear elliptic equations with p(x)-Laplacians in general domains

open access: yesElectronic Journal of Differential Equations, 2013
Oscillation of quasilinear elliptic equations with p(x)-Laplacians in general domains are derived by the variational approach as applications of Picone identity. Three examples are given, and generalizations to quasilinear elliptic equations with $p(x)

Maximum Principles for Dynamic Equations on Time Scales and Their Applications

open access: yesJournal of Applied Mathematics, 2014
We consider the second dynamic operators of elliptic type on time scales. We establish basic generalized maximum principles and apply them to obtain weak comparison principle for second dynamic elliptic operators and to obtain the uniqueness of Dirichlet
