The Editor-in-Chief has retracted this Article due to substantial overlap with an unpublished manuscript by Dr. Georges Vles and colleagues. In addition to this, there is substantial overlap with another article by Aharram et al. which was under consideration at the same time [1].

None of the authors have responded to any correspondence from the editor or publisher about this retraction.
