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 73 research articles (2021–2026), authors are most often from Hungary (84.5%), Austria (3%) and United Kingdom (2.1%). More than half of recent authorship comes from one country.
Countries are counted fractionally, so a paper by authors from two countries counts half to each.
