Frequency‐Dependent Demethylation of Cancer DNAs by High‐Power Terahertz Radiation
Advanced Photonics Research, EarlyView.Effective demethylation of cancer DNA is successfully demonstrated by resonant irradiation with high‐power terahertz (THz) waves at the 10 mW level, combined with metamaterial‐based THz filters. The dependence of spectral filtering on demethylation indicates that the resonant frequency of 1.6 THz of cancer DNAs plays a crucial role in reducing the ...

Few-shot Named Entity Recognition via Superposition Concept Discrimination [PDF]
arXivFew-shot NER aims to identify entities of target types with only limited number of illustrative instances. Unfortunately, few-shot NER is severely challenged by the intrinsic precise generalization problem, i.e., it is hard to accurately determine the desired target type due to the ambiguity stemming from information deficiency.
