We’ve found a fourth retraction for a group of chemists in Iran who plagiarized.
As before, the offending article had appeared in Communications in Nonlinear Science and Numerical Simulation. This time, however, it did not include a co-author from Ball State University in Indiana, Robert Sammelson, whose name had appeared on three of the earlier papers.
The article was titled “An analytical approach to soliton of the saturable non-linear Schrödinger equation determination and consideration of stability of solitary solutions of cubic–quintic non-linear Schrödinger equation (CQNLSE),” and was written by Behrooz Adib and Alireza Heidari, of Islamic Azad University, and Sayyed Faramarz Tayyari of Ferdowsi University of Mashhad. It had been cited twice before being retracted, according to Thomson Scientific’s Web of Knowledge.
(One of the other retracted papers was titled “An analytical approach to the stability of solitary solutions of cubic–quintic coupled non-linear Schrödinger equation,” which is close enough to raise questions about the probability of those two articles being different enough for both to warrant publication in the first place.)
According to the notice:
This article has been retracted at the request of the Editor-in-Chief and the authors.
The authors have plagiarized part of a paper that had already appeared in the Iranian Journal of Physics Research 2(2) (2000) 103–111 and 4(1) (2003) 41–47. 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 a severe 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.
