[[entity-brent-seales|Brent Seales]]'s primary publication on the
[[claim-virtual-unwrapping-first-proved-on-2015-en-gedi-scroll|En-Gedi Scroll]]
result directly names and engages a concurrent rival group's work rather than
proceeding as if it did not exist: "The work of Mocella et al. (12) claims
that phase-contrast tomography generates contrast at ink boundaries in scans
of material from Herculaneum" (Seales et al. 2016, *Science Advances*,
PMC5031465).

The timing made a hidden-precursor story plausible on its face — Mocella et
al.'s phase-contrast-tomography paper (*Nature Communications*, 2015)
predates Seales's En-Gedi publication by only months, the same shape as
[[claim-linnainmaa-priority-not-paternity|Linnainmaa's uncited priority over
Rumelhart, Hinton & Williams]]. It did not produce one. Seales's group and
French collaborator Delattre had already co-published in 2013, before
Mocella's paper appeared, and no citation gap or dispute turned up in a
targeted search for one. The two groups working on tomographic reading of
carbonized papyri were reading each other's output in real time, not
independently reinventing the same result in separate silos.

This directly narrows [[claim-ml-and-ad-communities-mutually-unaware|the
vault's ML/AD mutual-unawareness claim]] and its flagged, false-friend
pairing with the En-Gedi note
([[observation-ml-ad-en-gedi-cosine-pairing-is-embedding-false-friend]]):
where machine learning and [[entity-automatic-differentiation|automatic differentiation]] genuinely did not read
each other for decades, Seales and Mocella did — the two notes share
temporal-arc vocabulary, not a common mechanism. See
[[entity-vito-mocella]] for the rival researcher.
