A quick ArXiv search for any papers by Dr. Franklin Felber reveals ... none.
Maybe it was too quick:
try this
http://arxiv.org/find/ with Felber and you get

But, as I posted earlier,
http://www.freerepublic.com/focus/f-news/1576777/posts?page=175#175 if his calculations are correct then the assumptions for GEM has to be updated.
