Automated Lexical Coverage for Language Learning: From General to Specialized Word Lists

Announce Type: replace Abstract: A General Service List (GSL) is a commonly used resource for language learners to identify important English words. Traditional GSL creation is resource-intensive, relying on linguistic expertise and subjective input. We created our own GSL and evaluated its performance against the New General Service List (NGSL).

Elevated temperature drives the biosynthesis of novel acylated glucosinolates in Arabidopsis thaliana seeds

Glucosinolates (GSLs) are major defensive compounds massively accumulated in Brassicaceae seeds, including that of the model plant Arabidopsis thaliana. While most studies have focused on the role of GSL in responses to biotic stress, the potential regulation and function of GSLs in responses to abiotic stresses have been neglected, particularly in seeds. In this study, multi-omic analyses revealed a previously uncharacterized GSL modification pathway induced by elevated temperature (ET)...

ATML1-GIR1-TPL/TPR transcriptional repression module controls glucosinolates and giant cells in Arabidopsis thaliana sepals

Glucosinolates (GSLs) are sulfur- and nitrogen-containing secondary metabolites that serve as defense compounds in Arabidopsis and other members of the Brassicales. Although the enzymatic pathway that produces GSLs is well-studied, the upstream mechanisms that control their tissue-specific synthesis are poorly understood. We identified a novel repression module that transcriptionally regulates GSL levels in sepals, the modified leaves that protect reproductive tissues within the floral bud.

Extreme envelope plasticity drives temperature-dependent morphogenesis in the LPS-free bacterium Sphingobium yanoikuyae

Bacterial growth patterns are generally considered to be constrained and species-specific. Here, we show that Sphingobium yanoikuyae exhibits exceptional plasticity in envelope architecture and morphogenesis driven by a glycosphingolipid (GSL)-based outer membrane and an atypical peptidoglycan structure. At 30{degrees}C, cells expand asymmetrically via a rare bipolar envelope synthesis mode, whereas growth at 37{degrees}C triggers a transition toward longitudinal elongation accompanied by...

Target-Side Paraphrase Augmentation for Sign Language Translation with Large Language Models

arXiv:2605.31393v1 Announce Type: new Abstract: Sign language translation (SLT) remains constrained by limited paired sign-video/text corpora and heavy-tailed target vocabularies. We study target-side augmentation in which GPT-4o generates controlled paraphrase variants of reference sentences while the sign input remains unchanged. A Signformer-style pose-based Transformer is trained under a two-stage schedule: pre-training on the augmented corpus followed by fine-tuning on the original...
