This paper describes a new approach to generating command-line argument parsers in Perl [1]. The system presented takes a standard "usage" description and reverse-engineers a parser which satisfies that description. This ability to specify complex parsers declaratively also proves useful in other contexts, such as comma-separated-value processing, simple input parsing, and string interpolation.

Difference systems of sets can be used to transform an arbitrary linear code to a coset of a linear code with a given comma-free index by means of a minimal increase of its length. The paper discusses some constructions of difference systems of sets obtained from cyclic difference sets and finite geometry.

PURPOSE/OBJECTIVES To describe relationships among perceived barriers to symptom management and quality of life and to test the mediating role of perceived communication difficulties on the relationships between other perceived barriers to symptom management and quality of life in older adult breast cancer survivors. DESIGN Cross-sectional descriptive-correlational design using baseline data ...

Let C and A be categories and P : C → A a functor which is bijective on objects and surjective on arrows; then C is an extension of A. This notion of extension is studied here from the point of view of classifying and synthesizing extensions, by generalizing methods used in studying extensions of groups and semigroups. (Functors which merge objects don’t behave so much like homomorphisms and pr...

‎This paper develops a basic theory of $H$-groups‎. ‎We‎ ‎introduce a special quotient of $H$-groups and‎ ‎extend some algebraic constructions of topological groups to the category‎ ‎of H-groups and H-maps and then present a functor from this category to the category of quasitopological groups‎.

in addition to exploring constructions and properties of limits and colimits in categories of topologicalalgebras, we study special subcategories of topological algebras and their properties. in particular, undercertain conditions, reflective subcategories when paired with topological structures give rise to reflectivesubcategories and epireflective subcategories give rise to epireflective subc...

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 ...
