Richard,
Thanks for that!
(The copyright statement appears at the bottom of the very pdf you provide! But in any case a copyright statement is not actually necessary to ensure copyright protection.)
This work is not in the public domain (yet). But I withdrew this work only to ensure compliance with journal publishing embargo requirements. If I get no success with the academic route (I have re-submitted a proposal), I will re-release my work and let people make of it what they will. I know when to quit.
