PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

This comment is to correct an error in equation (1-6) of the paper. I have uploaded an Errata file on my website (http://www14.plala.or.jp/sikajiro/errata_24555693.pdf). This is a typographical error and does not change the results of the paper. We  apologize for any inconvenience.
