This paper is fascinating and was submitted by one resident. I have been lucky to have him as a collaborator as well as interact on Telegram. This was unique as I had not read this paper before.
The usual disclaimers apply- submission was done anonymously. Only the word summary can be downloaded. The purpose of the blog is educational and I don’t have any commercial interest in either distribution of the content or it’s display (I don’t earn any revenue from the blog).
