    Why Large Language Models Seem to Overuse Em-Dashes: Evidence, Mechanisms, and Limits of a Widely Noticed AI-Writing Signal

    A cautious research review of the em-dash as an AI-writing signal: what has been measured, why the pattern may emerge, and why a punctuation mark is not authorship proof.

    Cost-Aware Language Adaptation in Large Language Models: A Framework for Low-Resource Languages

    A targeted literature synthesis on adapting large language models for low-resource languages under practical constraints: tokenization efficiency, compute, and catastrophic forgetting.
