One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents an abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process. Journal records indicate that confirmation of the submission and publication of the article was sent to the first author’s email address and the individual listed as the corresponding author did not receive any correspondence from the journal throughout the submission process.
