Transition from hyperbolicity to ellipticity for a p-system with viscosity
Electronic Journal of Differential Equations, 2019 In this article we consider a viscous regularization of a p-system with a Van der Waals pressure law, which presents both hyperbolic and elliptic zones.

Current‐Driven Chirality Detection of Magnetic Textures in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Current‐assisted anisotropic magnetoresistance measurements in individual Ni/Au cylindrical nanowires enable detection of vortex chirality near Au segments and selective magnetic reversal in defined wire sections at magnetic fields lower than the propagation field. This approach provides a simple, cost‐effective, and non‐invasive method for probing and

Existence of positive entire radial solutions to a $(k_1,k_2)$-Hessian systems with convection terms
Electronic Journal of Differential Equations, 2016 In this article, we prove two new results on the existence of positive entire large and bounded radial solutions for nonlinear system with gradient terms $$\displaylines{ S_{k_1}(\lambda (D^{2}u_1) )+b_1(| x| ) | \nabla u_1|^{k_1} =p_1(| x| ) f_1 ...

A sub-elliptic estimate for a class of invariantly defined elliptic systems [PDF]
Pacific Journal of Mathematics, 1981 We consider a certain invariantly defined nonlinear system of partial differential equations on a Riemannian manifold. Since a special case describes a steady, irrotional, compressible flow on the manifold, it is natural to refer to the (square of) the pointwise norm of the solution as the speed of the flow and to the density of the flow.

Homogenization of singular elliptic systems with nonlinear conditions on the interfaces [PDF]
, 2020 We prove existence and homogenization results for elliptic problems involving a singular lower order term and defined on a domain with interfaces having a nonlinear response.

Advanced Functional Materials, EarlyView.A graphene‐supported 2D metal–organic network stabilizes highly reactive Fe(I)‐N4 single sites through Co‐induced charge redistribution. Combined experiments and theory reveal Fe(I) formation, oxygen‐driven oxidation, and O2 activation mechanisms, offering a strategy to access low‐valent iron centers relevant to catalytic and biological processes ...
