This article has been retracted at the request of the Editor.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 suspicious changes in authorship after acceptance of this paper. Following acceptance, the authors Syed Noorul Shajar, Md. Moneef Ahmad, and Abdul Ghani Faiyyaz were added to the paper and four authors were added then removed without exceptional approval by the journal Editor, which is contrary to the journal policy on changes to authorship. The journal reached out to the authors for an explanation, but they failed to provide a satisfactory explanation to these changes. The Editor has determined that the authorship and the findings of the article cannot be relied upon, and has decided to retract the article.
The authors disagree with retraction and dispute the grounds for it.
