Reference health
Switch from specialized to generalized pollination
2/2 checkable references clean · checked 2026-08-30
Every reference with a DOI or an arXiv id in the deposited reference list resolved to a known
work in Crossref or DataCite at the dated check, and none carried a retraction,
withdrawal, or removal notice.
8 with no DOI or arXiv id: not checked. A reference
deposited without a DOI is checked only when it names an arXiv id, under that id’s DataCite
DOI. The rest are never matched by title or guessed at; they stay outside the checked set, and
this line says so.

What this badge says. CiteStamped means the CHECKABLE references of this
work were clean at the dated check: each resolved to a known work in a public registry, and none
carried a retraction notice at that time. If Crossref’s record marks the work itself
retracted, withdrawn, or removed, the badge says so instead of showing clean. It says nothing
about the quality, findings, or importance of the work itself, and nothing about references
with neither a DOI nor an arXiv id.
checked 2026-08-30 — re-checked at most once a day, when someone opens
this page, so the date shown is the last check; titles and statuses come from Crossref and DataCite and are not
part of the signed record
