I don't understand the downvoting; the MIT Press release could at least point to the research backing the claims, which I guess could be: https://research.iuss

I don't understand the downvoting; the MIT Press release could at least point to the research backing the claims, which I guess could be: https://research.iusspavia.it/handle/20.500.12076/265 https://research.iusspavia.it/handle/20.500.12076/265 Or, despite being too recent to be in the book: https://research.iusspavia.it/handle/20.500.12076/1463 https://research.iusspavia.it/handle/20.500.12076/1463 (of the latter, I guess that this link: http://150.162.46.34:8080/embc-2015/papers/13891714.pdf http://150.162.46.34:8080/embc-2015/papers/13891714.pdf is a summary)
