The Editors-in-Chief have discovered distinct similarities between this paper and several other published papers. Moreover, it was discovered that an author who made a substantial contribution to the research was omitted from the authorship of the paper. Thus, the Editors-in-Chief have requested that the paper be rejected for publication and removed from the website. However, given that the Can. J. Phys. version of the paper has already been published, this is not possible and so the Editors-in-Chief of Can. J. Phys. are retracting it. Note that the paper being retracted was published only in the electronic version of Can. J. Phys. as a Just-IN manuscript and that it was not incorporated into a print issue.
