This article has been retracted at the request of the Editor.
Post-publication, an investigation conducted on behalf of the journal by Elsevier's Research Integrity & Publishing Ethics team discovered substantial changes in authorship between the original submission and the revised version of this paper. During revision, the authors Ling Shing Wong, Vinoth Kumarasamy, Gaurav Gupta, Vetriselvan Subramaniyan, and Naveed A. Malik were added to the revised paper without adequate explanation. The Editor does not have confidence that all of the stated authors of the article qualify for authorship and has therefore lost confidence in the validity/integrity of the article and made the decision to retract.
The authors disagree with retraction and dispute the grounds for it.
