Reply to Chmielewski and Snyder-Mackler.

REPLY: In the letter of Chmielewski and Snyder-Mackler, the authors pointed out that the clinical classification scheme used in their studies is not comparable to ours to separate anterior cruciate ligament (ACL) patients without “giving-way symptoms” (copers) from ACL patients with giving-way symptoms (noncopers). In contrast to their comprehensive screening protocol that included issues of di...

We introduce the notion of a half-ribbon Hopf algebra, which is a Hopf algebra H along with a distinguished element t ∈ H such that (H, R,C) is a ribbon Hopf algebra, where R = (t ⊗ t)∆(t) and C = t. The element t is closely related to the topological ‘half-twist’, which twists a ribbon by 180 degrees. We construct a functor from a topological category of ribbons with half-twists to the categor...
