Beyond Co-Localization: DeepCoEx Learns Exclusion-Aware Spatial Representations in Mass Spectrometry Imaging via Dual-Contrastive Learning

Abstract Mass spectrometry imaging (MSI) provides spatially resolved molecular profiles, yet the existing computational workflows are heavily biased toward co-localization and remain limited in characterizing exclusion-like spatial relationships, especially when reliable negative...

Automated In-InjectorPort Conversion of AristolochicAcids to Aristolic Acids for Enhanced HPLC Fluorescence Detection

Abstract Aristolochic acids (AAs) and the herbs containing them are recognized human carcinogens. Emerging evidence indicates that AAs are also food and environmental contaminants, posing significant risks to human health. This study developed a highly sensitive AA detection meth...
