We present a new and shorter proof of Stocking's result that any strongly irreducible Heegaard surface of a closed orientable triangulated 3– manifold is isotopic to an almost normal surface. We also reprove a result of Jaco and Rubinstein on normal spheres.

Recurrent dislocation of patella may occur in patients with ligament laxity. Method of treatment in this condition is controversial but patellofemoral ligament reconstruction is the most accepted method. We present a patient with Rubinstein-Taybi syndrome and recurrent patellar dislocation who managed successfully by patellofemoral ligament reconstruction.

BACKGROUND Thong style flip-flops are a popular form of footwear for children. Health professionals relate the wearing of thongs to foot pathology and deformity despite the lack of quantitative evidence to support or refute the benefits or disadvantages of children wearing thongs. The purpose of this study was to compare the effect of thong footwear on children's barefoot three dimensional foot...

We study an evolution equation proposed by Chapman-Rubinstein-Schatzman as a mean-field model for the evolution of the vortex-density in a superconductor. We treat the case of a bounded domain where vortices can exit or enter the domain. We show that the equation can be derived rigorously as the gradient-flow of some specific energy for the Riemannian structure induced by the Wasserstein distan...

This paper starts with a re-examination of Piccione and Rubinstein’s [Games Econ. Behav. 20 (1997) 3] Absent-Minded Driver problem, and suggests a novel interpretation of Aumann, Hart and Perry’s [Games Econ. Behav. 20 (1997) 102] notion of action-optimality. We then consider several variants of the original problem in which the assumption that the player’s information sets partition the set of...

The clinical evaluation of the hallux abducto valgus deformity is extremely important. It is imperative that the nature and type of deformity are identified and documented to understand the presenting problem unique to each patient. Of equal importance is the fact that many patients presenting with hallux abducto valgus and associated symptoms will require surgical intervention to adequately tr...

Abstract: We investigate the problem of decomposing an image into three parts, namely a cartoon part, a texture part and a noise part. We argue that norms originating in the theory of optimal transport should have the ability to distinguish certain noise types from textures. Hence, we present a brief introduction to optimal transport metrics, especially the Kantorovich-Rubinstein norm, and show...

INTRODUCTION Thong style flip-flop footwear and sandals are the preferred footwear of 22% of children in Australia [1]. However, little is known about the effects of thong wearing on the growing child, despite thongs being identified by parents as a primary contributor to children’s total foot complaints with 15% of forefoot and 22% of rearfoot foot complaints attributed to thong and sandal wea...
