Local Robustness of Bound States in the Continuum through Scattering-Matrix Eigenvector Continuation

This paper establishes a general topological framework for understanding the local robustness of bound states in the continuum (BICs) by characterizing them as isolated zeros of a parameter-to-coefficient mapping derived from scattering-matrix eigenvectors, thereby providing both a theoretical explanation for their phase singularities and a practical numerical criterion for their detection.

Nondestructive assessment of ripeness in kiwifruit with near-infrared pulse illumination

This paper presents a nondestructive method for assessing kiwifruit ripeness using near-infrared pulse illumination at 800 nm, introducing two nonmonotonic indices (relative ripeness and the first Wasserstein distance) to quantify temporal light profile changes observed over a ten-day period.

Stability analysis and quantum-limited noise properties of the Soliton-similariton fiber laser

This paper establishes that the anomalous dispersion segment in soliton-similariton fiber lasers is the primary source of their exceptional stability and low quantum-limited noise, demonstrating through linear stability analysis and simulations that a positive stability margin in this segment directly correlates with reduced timing jitter and intensity noise.

Scaling law from orbital angular momentum conservation in harmonic and high-order harmonic generation driven by spatiotemporal light fields

This paper identifies a generalized scaling law for conserved orbital angular momentum in harmonic generation driven by diverse spatiotemporal light fields, resolving the limitations of the traditional Laguerre-Gauss topological charge rule and explaining previously unintelligible phenomena.

Nanosecond wavefront shaping to focus through agitated turbid media

This paper demonstrates the first successful closed-loop wavefront shaping capable of maintaining stable optical focusing through rapidly agitated, highly turbid media by operating at a correction bandwidth that matches the medium's sub-microsecond decorrelation rate.

Fourier Transform Infrared microspectroscopy-based super-resolution virtual staining of unlabeled tissues by pixel Diffusion Transformer

This paper presents a diffusion transformer-based method that achieves fourfold pixel-level super-resolution and fourfold inference speed improvements by transforming low-resolution, unlabeled FTIR microspectroscopic images of human lung tissue into high-resolution, clinically usable H&E-stained images through a stochastic Brownian bridge process in pixel space.

Ponderomotive Achromat for Electron Optics: Radially Polarized Annular Focusing and a Round-Lens Corrector Regime

This paper demonstrates that by exploiting Lorentz-boost-induced polarization mixing in radially polarized annular optical fields, it is possible to engineer a ponderomotive electron lens that achieves both energy achromatization and negative on-axis chromatic aberration, offering a compact corrector regime for relativistic electron optics.
