The paper develops the Recovery-Burden Index (RBI), a glucose-only metric from OGTT profiles that accurately predicts DI and detects beta-cell dysfunction.

The paper introduces HRPI, a threshold-free metric for sustained heart rate elevation, and shows it captures more structure than mean HR and declines with age.

The paper investigates NRAC's role in reciprocal adipose-heart regulation of fatty acid metabolism across nutritional states using human and mouse data.

The paper introduces the PC-index, a composite metric that integrates gene expression magnitude and prevalence in single-cell RNA-seq data, demonstrating its application in human adipocytes.
