On Stability of a Third Order of Accuracy Difference Scheme for Hyperbolic Nonlocal BVP with Self-Adjoint Operator

open access: yesAbstract and Applied Analysis, 2013
A third order of accuracy absolutely stable difference schemes is presented for nonlocal boundary value hyperbolic problem of the differential equations in a Hilbert space H with self-adjoint positive definite operator A. Stability estimates for solution

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Breather solitons in highly nonlocal media

open access: yes, 2016
We investigate the breathing of optical spatial solitons in highly nonlocal media. Generalizing the Ehrenfest theorem, we demonstrate that oscillations in beam width obey a fourth-order ordinary differential equation.

The nonlocal problem for the differential-operator equation of the even order with the involution

open access: yes, 2018
In this paper, the problem with boundary nonself-adjoint conditions for a differential-operator equations of the order $2n$ with involution is studied. Spectral properties of operator of the problem is investigated.

Enhanced Trapping with an Optimized Graphene‐Based Bowtie Plasmonic Nanotweezer: Design, Analysis, and Bioanalytical Applications

open access: yesAdvanced Photonics Research, EarlyView.
A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

Nonlocal symmetries and recursion operators: Partial differential and differential–difference equations

open access: yesJournal of Mathematical Analysis and Applications, 2005
After brief explanation of the basic definitions and notions connected with nonlocal symmetries of DEs the authors present a systematic method to derive the nonlocal symmetries for PDEs with two independent variables and show that KdV \(\frac{\partial u}{\partial t}=u\frac{\partial u}{\partial x}+\frac{\partial ^3 u}{\partial x^3}\) and Burgers \(\frac{

On the Second Order of Accuracy Stable Implicit Difference Scheme for Elliptic-Parabolic Equations

open access: yesAbstract and Applied Analysis, 2012
We are interested in studying a second order of accuracy implicit difference scheme for the solution of the elliptic-parabolic equation with the nonlocal boundary condition. Well-posedness of this difference scheme is established.

Deep learning schemes for parabolic nonlocal integro-differential equations

open access: yesPartial Differential Equations and Applications, 2022
AbstractIn this paper we consider the numerical approximation of nonlocal integro differential parabolic equations via neural networks. These equations appear in many recent applications, including finance, biology and others, and have been recently studied in great generality starting from the work of Caffarelli and Silvestre by Lius and Lius (Comm ...

Redox‐Responsive Tellurium‐Bridged Covalent Organic Frameworks/PEG Composites for Targeted Therapy of Diabetic Cardiomyopathy

open access: yesAdvanced Science, EarlyView.
This study unlocks the immense potential of COF@polymer nanocomposites as a multifunctional therapeutic platform for targeted drug delivery in diabetic cardiomyopathy. Abstract Diabetic cardiomyopathy, a major complication of diabetes, is strongly associated with elevated levels of glycated hemoglobin (HbA1c) and reactive oxygen species (ROS). However,
