Fe3+-mediated fluorescence switching of biomass-derived carbon dots integrated with PVA microneedles for smartphone-assisted determination of ascorbic acid in fruits and vegetables.

Rapid and accurate determination of ascorbic acid (AA) is important for evaluating the nutritional quality of fresh produce. In this study, biomass-derived carbon dots (CDs) were synthesized from pomelo peel in a green deep eutectic solvent, and Fe3+ was subsequently coordinated with the CDs to construct an off-on fluo...

SignRAG: Unified Retrieval-Augmented Gloss-Free Sign Language Translation

Contemporary decoder-only large language models (LLMs) have demonstrated strong capabilities across a wide range of domains. However, existing pretraining paradigms for gloss-free sign language translation (SLT) are largely designed around conventional encoder-decoder pretrained language models, which limits their dire...
