Why the AD Scientific Index Matters
Unlike traditional rankings, the AD Scientific Index evaluates institutions based on the H-index, i10-index, and citation counts across both lifetime and the last five years of performance. This dual perspective captures both historical academic strength and recent momentum, offering a more balanced and transparent assessment.
