We provide a new presentation for the annular braid group. The annular braid group is known to be isomorphic to the finite type Artin group with Coxeter graph B n. Using our presentation, we show that the annular braid group is a semidi-rect product of an infinite cyclic group and the affine Artin group with Coxeter graph˜A n−1. This provides a new example(More)
A clinical evaluation of the Easy-Flow External Condom Catheter (Delphi Medical Products) was performed on incontinent patients of the Salt Lake City VA Medical Center.
