The performance and success of many self-timed design methodologies commonly rely heavily on completion detection schemes in order to reliably acknowledge the termination of a computation associated with a self-timed functional block. A particularly vexing problem associated with many self-timed completion detection schemes proposed in the literature, is(More)
Xerostomia, the subjective complaint of dry mouth, and hyposalivation remain a significant burden for many individuals. Diagnosis of xerostomia and salivary gland hypofunction is dependent upon a careful and detailed history and thorough oral examination.

1 The Theorem Let Γ be a finitely-generated group, and S 1 the circle of radius 1 with metric d: S 1 × S 1 → [0, π]. We let ϕ: Γ × S 1 → S 1 denote an action of Γ on the circle by homeomorphisms. For notational convenience, given γ ∈ Γ we let γx = ϕ(γ)(x). Definition 1.1 The action ϕ: Γ × S 1 → S 1 is expansive if there exists > 0 so that for any pair x = y(More)
