On nonlocal quasilinear equations and their local limits

open access: yes, 2016
We introduce a new class of quasilinear nonlocal operators and study equations involving these operators. The operators are degenerate elliptic and may have arbitrary growth in the gradient.

Maximal regular boundary value problems in Banach-valued function spaces and applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
The nonlocal boundary value problems for differential operator equations of second order with dependent coefficients are studied. The principal parts of the differential operators generated by these problems are non-selfadjoint.

Relation between nonlocal surface and bulk dark solitons

open access: yesResults in Physics, 2018
We investigate the existence and stability of nonlocal surface dark solitons at the interface formed by a nonlocal nonlinear self-defocusing medium and a linear medium.

A Class of Nonlocal Coupled Semilinear Parabolic System with Nonlocal Boundaries

open access: yesThe Scientific World Journal, 2014
We investigate the positive solutions of the semilinear parabolic system with coupled nonlinear nonlocal sources subject to weighted nonlocal Dirichlet boundary conditions. The blow-up and global existence criteria are obtained.

Polyhydroxy‐Decorated 2D Covalent Organic Framework with Imine Active Sites toward Efficient Electrocatalytic Oxygen Reduction Reaction: Experimental and Theoretical Insights

open access: yesChemistry – An Asian Journal, EarlyView.
Hydroxyl‐functionalized enamine/imine‐linked two‐dimensional (2D) COFs (TFPh_DHPh_COF) exhibits efficient and durable metal‐free ORR activity in alkaline media via a favorable 4e⁻ pathway. Enhanced charge transfer and O2 activation arise from tailored linkages and active‐site charge distribution.

No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.
