We have noticed some authors who are publishing at a rate that is exceptionally high.
(1) An author of a recent submission has published over 100 articles since January 2005; he had published fewer than 50 in the preceding 5 years. This is quite a sudden increase. On average, he published 1 article every 8 days in 2005, and in 2006 this increased to 1 every 4 days. The author is on the board of his institute, and is a department head.
