Critical System Size for the Recovery of Topological Zero Modes in Finite Non‐Hermitian Systems

Annalen der Physik, Volume 537, Issue 12, December 2025.
A generalized non‐Hermitian SSH model on a topolectrical circuit reveals size‐dependent topological zero modes. Non‐Hermiticity enables exact zero‐admittance edge states at a critical system size, tunable via asymmetric coupling and gain/loss. Large impedance peaks signal these modes, offering insights for designing robust topological devices with ...

Exploring Aromaticity in Expanded Porphyrins: A Multidimensional Approach to Structure–Property Relationships

Chemistry–Methods, Volume 5, Issue 12, November 2025.
Expanded porphyrins, with their flexible structures and rich redox chemistry, offer a powerful platform to explore how aromaticity shapes molecular properties. This review introduces a multidimensional framework to quantify Hückel and Möbius aromaticity and examines its impact on the spectroscopic behavior across redox‐ and topology‐controlled expanded

Mild solutions to Love-type equations on R^2

Electronic Journal of Differential Equations
In this article, we study a non-local Love problem on unbounded domains where the non-locality in the main equation is interpreted as a fractional Laplacian operator.

Singular critical elliptic problems with fractional Laplacian

Electronic Journal of Differential Equations, 2015
In this article, we consider the existence of solutions of the critical problem with a Hardy term for fractional Laplacian $$\displaylines{ (-\Delta)^s u -\mu \frac u{|x|^{2s}}= u^{2^*_s-1} \quad \text{in }\Omega,\cr u>0 \quad \text{in }\Omega, \cr

What Is the Fractional Laplacian?

, 2018
The fractional Laplacian in R^d has multiple equivalent characterizations. Moreover, in bounded domains, boundary conditions must be incorporated in these characterizations in mathematically distinct ways, and there is currently no consensus in the literature as to which definition of the fractional Laplacian in bounded domains is most appropriate for ...

Zero‐DAGNet: A Domain‐Adversarial Graph Network Integrated With POCO for Cyber‐Physical Security in Smart Grid

Energy Science &Engineering, Volume 13, Issue 12, Page 6430-6456, December 2025.
Proposed CPS for smart grid. ABSTRACT Smarter grids depend on Cyber‐Physical Systems (CPS) to merge physical energy distribution networks with computational intelligence, because these systems optimize reliability and sustainability and power delivery efficiency.

A finite-volume scheme for fractional diffusion on bounded domains

European Journal of Applied Mathematics
We propose a new fractional Laplacian for bounded domains, expressed as a conservation law and thus particularly suited to finite-volume schemes. Our approach permits the direct prescription of no-flux boundary conditions.

Widefield Targeted Illumination Microscopy Enables Optically‐Sectioned, Motion‐Resilient Imaging of Neuronal Fibers and Their Dynamics

Laser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.
Targeted Illumination Microscopy (TIM) enhances widefield fluorescence imaging by selectively illuminating dim neuronal fibers while suppressing bright cell bodies. Using real‐time image processing and a digital micromirror device, TIM achieves high‐contrast, optically sectioned, and motion‐resilient imaging in C.
