The Editor-in-Chief has retracted this article. Concerns were raised regarding Fig. 7: Fig. 7C appear to be identical to Fig. 7B but stretched and cropped. Additionally, the correction published for this article [1] appears to contain an error, as it was intended to correct Fig. 4. The authors have provided additional figures but in the view of the editors this was not sufficient to address the concerns. The Editor-in-Chief therefore no longer has confidence in the results and conclusions of this article.

Authors Nabil A. Alhakamy and Zuhier A. Awan agree to this retraction. Author Usama A. Fahmy does not agree to this retraction. Authors Ahmed L. Alaofi and Hani M. Alqarni have not responded to any correspondence from the editor or publisher about this retraction.
