This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal).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This article has been retracted at the request of the Editors-in-Chief.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 conflict of interest related to the submission and review of this paper. Review of this submission was handled by Guest Editor Chin Kui Cheng despite an extensive recent record of collaboration, including co-publication, with one of the paper co-authors (Pau Loke Show). Acceptance of the article was partly based upon the positive advice of a reviewer who was closely linked to one of the authors (Show). In addition, the reviewer's report was edited by a user with a name matching one of the authors (Revathy Sankaran). This compromised the editorial process and breached the journal's policies. The authors disagree with this retraction and dispute the grounds for it.>
