h-index, i10-index and 2-year mean citedness are open, licence-clear metrics from OpenAlex — not a proprietary impact factor. The subject rank counts only journals that OpenAlex has a figure for; it is not a Scopus or Clarivate ranking. Updated 2026-10-14.
In its latest 79 research articles (2025–2026), authors are most often from Iran (14.6%), India (9%) and Ethiopia (7.6%).
