Just setting the record straight.
I agree with you on the definitions. These men are the authors of the paper: Nathan H. Lents, Abhishek Venkatratnam. They chose the word "adulterant" for some reason. One is a grad student, the other appears to be some sort of genius. Meh, I have a few 500, and 600 level courses under my belt, but my brilliance is often equated with a small appliance light bulb.
