aim : the aim of present study was to screen two categories of psychiatric disorders in chronic functional constipation. background : it has been established that the prevalence of mood and anxiety disorders among patients with functional gastrointestinal disorders is higher than in the general population. patients and methods : fifty four constipated patients were recruited from patients refer...

Arrows are an extension of the well-established notion of a monad in functional programming languages. This article presents several examples and constructions, and develops denotational semantics of arrows as monoids in categories of bifunctors C×C→ C. Observing similarities to monads – which are monoids in categories of endofunctors C→ C – it then considers Eilenberg-Moore and Kleisli constru...

We propose and study a class-expansion/innovation/loss model of genome evolution taking into account biological roles of genes and their constituent domains. In our model, numbers of genes in different functional categories are coupled to each other. For example, an increase in the number of metabolic enzymes in a genome is usually accompanied by addition of new transcription factors regulating...

in this survey, we give an overview over some aspects of the set of tilting objects in an $m-$cluster category, with focus on those properties which are valid for all $m geq 1$. we focus on the following three combinatorial aspects: modeling the set of tilting objects using arcs in certain polygons, the generalized assicahedra of fomin and reading, and colored quiver mutation.

these are notes from introductory survey lectures given at the institute for studies in theoretical physics and mathematics (ipm), teheran, in 2008 and 2010. we present the definition and the fundamental properties of fomin-zelevinsky’s cluster algebras. then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generators of ...

OBJECTIVES Outcome prediction for pediatric heart surgery has focused on mortality but mortality has been significantly reduced over the past 2 decades. Clinical care practices now emphasize reducing morbidity. Physiology-based profiles assessed by the Pediatric Risk of Mortality (PRISM) score are associated with new significant functional morbidity detected at hospital discharge. Our aims were...
