Leighton and Rao use multicommodity flow results to design the first polynomial time approximation algorithms for well known NP-Hard optimization problems. Such problems include graph partitioning, crossing number, VLSI layout, and many more. Furthermore, Leighton and Rao are responsible for establishing the max-flow min-cut theorems on multicommodity flow problems, which lead to the algorithms...

Abstract Brief cognitive behavioural therapy (CBT) is effective in working with non-underweight eating disorder patients across transdiagnostic groups. However, it not clear whether will be as the treatment of binge-eating disorder, where emotional likely to play a larger role than starvation-driven eating. This case series tested brief, 10-session CBT (CBT-T) would 53 disorder. Attrition rates...

Formalised proofs of Cut admissibility often rely on the invertibility of the rules of a sequent calculus. We will present some sufficient conditions for when a rule is invertible with respect to a calculus, which we illustrate with many examples. Appropriate definitions are given for rarely defined intuitive notions, such as a formula being principal for a rule. It must be noted we give purely...

BACKGROUND Despite increasing recognition of the value of real-world data (RWD), consensus on the definition of RWD is lacking. OBJECTIVES To review definitions publicly available for RWD to shed light on similarities and differences between them. METHODS A literature review and stakeholder interviews were used to compile data from eight groups of stakeholders. Data from documents and inter...

Introduction: With the publication of four papers in late 2011, international cut-offs for definitions of non-viability in the first trimester of pregnancy were challenged. These definitions were inconsistent across different international guidelines. For example, a gestational sac with absent yolk sac or embryo and a mean diameter of ≥ 16 mm would be classified as a miscarriage in the USA, whe...

The age-related loss of muscle mass and/or strength and performance, sarcopenia, has been associated with geriatric syndromes, morbidity and mortality. Although sarcopenia has been researched for many years, currently there is a lack of consensus on its definition. Some studies define sarcopenia as low muscle mass alone, whereas other studies have recently combined low muscle mass, strength and...

OBJECTIVE This article compares prevalence estimates of excess weight among Canadian children and youth according to three sets of body mass index (BMI) reference cut-points. The cut-points are based on growth curves generated by the World Health Organization (WHO), the International Obesity Task Force (IOTF), and the US Centers for Disease Control (CDC). A secondary objective is to compare est...
