Competing Interests
Yes. I have read the journal's policy and the authors of this manuscript have the following competing interests: FBH: OHSU and FH have a significant financial interest in APDM, a company that may have a commercial interest in the results of this research and technology. This potential institutional and individual conflict has been reviewed and managed by OHSU. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
