Pattern Recognition in Physics was an open-access journal originally published by Copernicus Publications which was established in March 2013 and terminated in January 2014.

"[2] Concerns regarding the journal's peer-review process were first raised in July 2013 by Jeffrey Beall, an American librarian and critic of predatory open access publishing.

Beall wrote on his blog that Mörner did not appear to be a specialist in pattern recognition and that Ouadfeul's research had "only been cited a couple times."

He also said that "the editors selected the referees on a nepotistic basis, which we regard as malpractice in scientific publishing.
