Reasoning-Driven Design of Single-Atom Catalysts via a Multiagent Large Language Model Framework
Abstract Large language models (LLMs) are becoming increasingly applied beyond natural language processing, demonstrating strong capabilities in complex scientific tasks that traditionally require human expertise. This progress has extended into materials discovery, where LLMs in...

The paradox of human capital? Gendered precarious labor in the Korean Confucian gender regime
Purpose This study investigates the gendered dynamics of precarious labor in South Korea, an underexplored context in international scholarship. It examines how Confucian-influenced patriarchal norms relate to women's exposure to insecure employment despite rising educational att...

In block-design functional near-infrared spectroscopy (fNIRS), the resting baseline window is placed by convention rather than by derivation. We show that the recovery phase of the preceding hemodynamic response and anticipatory recruitment for the upcoming task act on that windo...

Wake-Up Call from the Past Investments
Asset impairment accounting requires firms to reassess their existing assets-in-place, namely, the outcomes of past investments, which enriches the information environment within the firm. We investigate whether this reassessment influences corporate investment strategies for lon...
