Competing Interests
The authors have read the journal's policy. Dr. Y. Iseri is working for a private company (the West Japan Engineering Consultants, Inc.). The RIHN possessed all the data and materials, because the RIHN and his company were making a contract of research support. Thus, this does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
