There only appears to be a single research paper looking for an implementation. I click to read, it takes me to google scholar. I click the article, it takes me through to a pay site, where I must pay $15 to read the article...
I've been using the Unpaywall[0] extension, and it's been a godsend. It'll detect if the webpage is about an academic paper, and it'll display a green icon on the side to click on which will take you to a free, legally open distribution channel.
