The catecholamine neurotransmitters, dopamine (DA), norepinephrine (NE) and epinephrine (EPI), are found in the retina in separate structures (Haggendal and Malmfors,1965; Hadjiconstantinou et al., 1984; Dowling et al., 1976). DA is associated with a subpopulation of amacrine cells and with interplexiform cells (Dowling et al., 1976). It is the most abundant catecholamine in the rat retina repr...

The complete and elementary symmetric functions are specializations of Schur functions. In this paper, we use this fact to give two identities for the complete and elementary symmetric functions. This result can be used to proving and discovering some algebraic identities involving rWhitney and other special numbers.

DEAR EDITOR, The group of reticulate pigmentary disorders includes the rare autosomal dominant Dowling–Degos disease (DDD) and Galli–Galli disease (GGD; OMIM 179850, 615327 and 615696). 1 In light of substantial clinical, histological and mutational overlap between GGD and DDD, they are considered to belong to the same entity. 2,3 Mutations in KRT5 (encoding keratin 5) have been associated with...

The Grothendieck compactness principle states that every norm compact subset of a Banach space is contained in the closed convex hull of a norm null sequence. In [1], an analogue of the Grothendieck compactness principle for the weak topology was used to characterize Banach spaces with the Schur property. Using a different analogue of the Grothendieck compactness principle for the weak topology...

A partial field P is an algebraic structure that behaves very much like a field except that addition is a partial binary operation, that is, for some a, b ∈ P, a + b may not be defined. We develop a theory of matroid representation over partial fields. It is shown that many important classes of matroids arise as the class of matroids representable over a partial field. The matroids representabl...

Reticulate acropigmentation of Kitamura (RAK) and Dowling-Degos Disease (DDD) are rare genodermatosis inherited as an autosomal dominant trait with variable penetrance. They are part of a spectrum of diseases with hyperpigmented macules coalescing in a reticular pattern, facial and palmoplantar pits, breaks in dermatoglyphics, comedo-like lesions and epidermoid cysts, and a unique histological ...

TreeMap is a computer program for analysing host-parasite cospeciation. We respond to Dowling’s (Cladistics, 18: 416-435) recent comparison of TreeMap and Brooks Parsimony Analysis (BPA) by showing that Dowling’s comparison suffers from several mistakes and flaws. We discuss the problems with both BPA and TreeMap, and show that BPA incorrectly counts the true number coevolutionary events more o...
