The Role of Instructional Guidance in Generative AI-Assisted Learning: Empirical Evidence from Construction Engineering Education

Xiaoyu Hou, Bo Xiao, Hexu Liu +1

Generative artificial intelligence (AI) is increasingly used to support self-directed learning, yet student interaction with such systems often remains unstructured, limiting engag…

On Effective Iitaka Fibration Indices for Stable Minimal Models with Large Iitaka Volumes

Hexu Liu

Given a pair $(V, C)$ that admits a stable minimal model with fixed dimension, fixed coefficient set, and bounded relative volume, we study when the linear system $∣ m (K_{V} + C) ∣$ induc…

A lifting principle for canonical stability indices of varieties of general type

Meng Chen, Hexu Liu

For any integer $n > 0$ , the $n$ th canonical stability index $r_{n}$ is defined to be the smallest positive integer so that the $r_{n}$ -canonical map $Φ_{r_{n}}$ is stably birational onto…
