摘要：

•The Uh-index surpasses the h-index in sensitivity, providing a refined measure of academic paper usage across disciplines.

•Empirical and theoretical analyses confirm the Uh-index's conformity with the Glanzel-Schubert model and power-law model, enhancing bibliometric rigor.

•Outlier journals across four subjects exhibit Uh-values significantly above average, demonstrating that the Uh index can identify types of high-performing journals by usage.

•The Uh-index offers a measure that bridges the gap between academic citation impact and social media influence, providing a new lens through which to observe academic impact.
