Ghost effect from Boltzmann theory

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

A Force‐Based Beam‐Column Element With Selective Gradient‐Inelasticity for Softening Materials in 3‐Dimensional Nonlinear Analysis

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.

Customized Scattering‐Robust 3D Speckle Correlation for Improved Resolution and Imaging Depth in Scattering Tissue

open access: yesLaser &Photonics Reviews, EarlyView.
A scattering‐robust 3D speckle customization method is proposed to enhance both resolution and imaging depth in scattering tissue. Applied to light‐field microscopy (LFM), it improves 3D resolution by over twofold under strong optical scattering. In wide‐field fluorescence imaging, it enables a substantial improvement in imaging depth, allowing imaging

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...
