The use of DOI links can prevent some potential readers of your paper to access them, because they follow the link and end up on paywalls without access to the paper (see an example here of a user not reading the paper for this reason). This pull requests replaces the links with links to publicly available version of the cited articles, and also add the author names to help further search of them (making references just as unique as the DOI numbers), in case one of those URLs became unavailable at some point in the future.
