Detectable, Task-Relevant, or Harmful? Construct-Valid Evaluation of Unlabeled Distribution-Shift Monitoring in Chest Radiography

Distribution-shift alarms do not establish classifier harm. We evaluated the detectability, frozen-head relevance, and performance deterioration of two public DenseNet-121 chest-radiography classifiers under 30 controlled image conditions. Signals covered pixels, 64-component PCA...

Synthesis, Phase Engineering and Optoelectronic Applications of Binary Arsenic Sulphide Thin Films from Orpiment to Dimorphite

Binary arsenic sulphide contains three thermodynamically stable compounds, orpiment (As2S3), realgar (As4S4) and dimorphite (As4S3), spanning a covalent layer network at the sulphur-rich end and discrete molecular cages at the arsenic-rich end. Thin-film research has concentrated...

Lightweight Near-Infrared Spectral Reconstruction from Red UAV Imagery Using Artificial Intelligence for Low-Cost Remote Sensing

Near-infrared imagery is essential for vegetation monitoring, precision agriculture, and environmental remote sensing, but multispectral UAV systems remain significantly more expensive and less accessible than conventional RGB imaging platforms. This study presents a lightweight...

Large-scale benchmarking of prokaryotic annotation tools across thousands of species

Abstract Background Genome annotation is an important step in deriving functional meaning from prokaryotic sequencing data, yet systematic evaluations guiding tool selection are lacking. We present the first large-scale investigation of four prominent open-source annotation tools...
