Pace count beads or ranger beads are a manual counting tool used to keep track of distance traveled through a pace count. It is used in military land navigation or orienteering. A typical example for military use is keeping track of distance traveled during a foot patrol. (Wikipedia).

David Masser: Avoiding Jacobians
Abstract: It is classical that, for example, there is a simple abelian variety of dimension 4 which is not the jacobian of any curve of genus 4, and it is not hard to see that there is one defined over the field of all algebraic numbers \overline{\bf Q}. In 2012 Chai and Oort asked if ther
