Most viewed authors and articles, downloads and engagement

Period

Usage statistics are recorded daily since 2013, with a 2021–2022 gap (2021 is nearly empty, 2022 is missing, 2023 is partial) and an undated legacy total (~430K views) that counts toward All time only. Views jumped sharply in 2025–2026 (~970K/year) — likely a mix of real traffic and crawler activity.

Most viewed authors

Sum of abstract views across all of the author's published articles (each co-author receives the article's full views). Author name variants are merged; homonyms are not disambiguated.

Most viewed articles

Abstract-page views. In the 5-year view only views recorded within the period count, regardless of how old the article is.

Most downloaded articles

PDF downloads, recorded daily since 2013 — unlike views, downloads carry no undated historical total, so period figures are directly comparable.

Engagement per article all time

PDF downloads per abstract view · articles with ≥150 views only · journal average: 0.21× across 1,023 articles with traffic

Shown over the full history for stability. A ratio above 1 means readers land directly on the PDF (e.g. from Google Scholar); the journal-wide average of 0.21 says most readers arrive at the abstract page first.
