This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief. A journal-wide investigation by Elsevier's Research Integrity & Publishing Ethics team identified violations of the journal's policies on authorship and conflict of interest related to the submission and review of this paper. Review of this submission was handled by Guest Editor Elena-Niculina Dragoi despite a recent record of collaboration, including co-publication, with four of the paper co-authors (Nevin Erk, Rozhin Darabi, Reza Mostafazadeh, Fuad Ameen). Acceptance of the article was partly based upon the positive advice of a reviewer who was closely linked to one of the authors (Darabi). In addition, authorship changes were made during the revision of this paper
the authors Darabi and M. Amirul Islam were added to the revised paper without validation or authorisation. This compromised the editorial process and breached the journal's policies. The authors disagree with this retraction and dispute the grounds for it.
