World Polio Day — October 24, 2014

In 1988, the World Health Assembly resolved to interrupt wild poliovirus (WPV) transmission worldwide. By 2006, the annual number of WPV cases had decreased by more than 99%, and only four remaining countries had never interrupted WPV transmission: Afghanistan, India, Nigeria, and Pakistan (1). The last confirmed WPV case in India occurred in January 2011 (2), leading the World Health Organizat...

A composition of an integer n is a k-tuple of positive integers whose sum is n. The number of these is 2n−1. In 1976 Carlitz considered compositions in which no two adjacent parts are equal, obtaining a closed form for their generating function. Via this generating function, it can be shown that the number of these Carlitz compositions is asymptotically Ar−n, where the constants A = 0.456 · · ·...
