Using Convolutional Neural Networks for the Classification of Suboptimal Chest Radiographs
This study evaluated DenseNet121 and YOLOv8 neural networks in detecting suboptimal chest x‐rays for quality control. Through training, validation, and testing, both AI models effectively classified chest X‐ray quality, highlighting the potential to provide radiographers with feedback to enhance image quality.

Quantum interference among vortex bound states in superconductors
In a recent experiment (Hou et al 2025 Phys. Rev. X 15 011027), a new type of necklace-like vortex bound state (VBS) was observed and attributed to disorder induced interference among different Caroli–de Gennes–Matricon (CdGM) states within one single ...

Large eddy simulation (LES) is used to investigate the structure of the laminar horseshoe vortex (HV) system and the dynamics of the necklace vortices as they fold around the base of a circular cylinder mounted on the flat bed of an open channel for Reynolds numbers defined with the cylinder diameter, D, smaller than 4460. The study concentrates on the

ABSTRACT Aim Population ecologists often focus on changes in the distribution and abundance of wildlife species, which are useful for trend analyses and status assessments. However, rarely are these responses evaluated simultaneously for a single species, despite their unique contributions to fully assess a species' viability.

Globally-Linked Vortex Clusters in Trapped Wave Fields
We put forward the existence of a rich variety of fully stationary vortex structures, termed H-clusters, made of an increasing number of vortices nested in paraxial wave fields confined by trapping potentials.

The Nature, Structure, and Perception of Illumination
ABSTRACT Illumination is a defining characteristic of natural environments, yet its nature and spatial structure remain poorly understood. I argue first that illumination is not simply light: it is an emergent, ecologically significant kind. Illumination has features not possessed by light, and contains self‐organizing structures that persist through ...

Cosmic Necklaces from String Theory [PDF]
We present the properties of a cosmic superstring network in the scenario of flux compactification. An infinite family of strings, the (p,q)-strings, are allowed to exist.

To overcome the porosity‐conductivity trade‐off in conductive porous membranes, a conductive nanofibrous membrane bridged by self‐assembled PPy nanowires is constructed, integrating multiscale porosity with continuous electron pathways. This material‐structure‐function strategy achieves low‐resistance and high‐efficiency filtration combined with ...

We modify the standard Abelian-Higgs model by introducing spatially-dependent couplings for the scalar and vector fields. We investigate static, non-cylindrically symmetric solutions of the resulting field equations and propose a pinch solution which ...
