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 96 research articles (2026), authors are most often from China (31.6%), United States (8.7%) and Italy (6.8%).
Countries are counted fractionally, so a paper by authors from two countries counts half to each.
Scopus status: Active. 4 retracted papers are recorded (1.5 per 1,000 papers). The Problematic Paper Screener flags none of its papers. These are indicators to check, not findings against the journal.
