Let K be an arbitrary field. Let (qn) be a sequence of positive integers, and let there be given a family \f¥nm\n > m} of unital Kmonomorphisms *F„m. Tqm(K) —► Tq„(K) such that *¥np*¥pm = %im whenever m < n , where Tq„ (K) is the if-algebra of all q„ x q„ upper triangular matrices over K. A triangular UHF (TUHF) K-algebra is any Kalgebra that is A'-isomorphic to an algebraic inductive limit of ...

The material was collected in three regions of Poland and consisted of 105 randomly chosen individuals killed during hunts (49 males, 56 females), out of which 51 were from Wielkopolska, 22 from Podkarpacie and 32 from Warmia. From each animal a blood sample was taken from the chest, stored in a probe with K2EDTA and frozen. The serum was used to establish the genotype for transferin and albumi...

A separoid is a symmetric relation † ⊂ ( 2 2 ) defined on pairs of disjoint subsets which is closed as a filter in the natural partial order (i.e., A † B C † D ⇐⇒ A ⊆ C and B ⊆ D). We discus the Geometric Representation Theorem for separoids: every separoid (S, †) can be represented by a family of (convex) polytopes, and their Radon partitions, in the Euclidean space of dimension |S| − 1. Furth...

Core-ML is a basic subset of most functional programming languages. It consists of the simply typed (or monomorphic)-calculus, simply typed equality over atomic constants, and let as the only poly-morphic construct. We present a synthesis of recent results which characterize this \toy" language's expressive power as well as its type reconstruction (or type inference) problem. More speciically: ...

Narcissus, the daffodil genus, exhibits an unusual diversity of sexual systems, with populations that are monomorphic, dimorphic or trimorphic for style length. Associated with this variation are striking differences among species in floral morphology and pollination biology. This diversity provides an opportunity to investigate the evolution of mating polymorphisms, and to determine how floral...

Three fundamental ontogenetic pathways lead to the development of size differences between males and females. Males and females may grow at the same rate for different durations (bimaturism), grow for the same duration at different rates, or grow at a mix of rate and duration differences. While patterns of growth and the development of adult body size are well established for many haplorhines, ...

Zoophilous flowers often transmit olfactory signals to attract pollinators. In plants with unisexual flowers, such signals are usually similar between the sexes because attraction of the same animal to both male and female flowers is essential for conspecific pollen transfer. Here, we present a remarkable example of sexual dimorphism in floral signal observed in reproductively highly specialize...

Although pooled-population sequencing has become a widely used approach for estimating allele frequencies, most work has proceeded in the absence of a proper statistical framework. We introduce a self-sufficient, closed-form, maximum-likelihood estimator for allele frequencies that accounts for errors associated with sequencing, and a likelihood-ratio test statistic that provides a simple means...

The regulator of G-protein signaling (RGS) modulates the functioning of heterotrimeric G protein. RGS9-2 is highly expressed in the striatum and plays a role in modulating dopaminergic receptor-mediated signaling cascades. Previous studies suggested that the RGS9 gene might contribute to the susceptibility to psychotic diseases. Therefore, we investigated the association between the RGS9 gene a...

Throughout its natural range, the brown trout Salmo trutta L. exhibits a complex pattern of morphological and life-history variation. This has led to considerable taxonomic confusion, hampering the understanding of the evolutionary history of the species. To document the phylogenetic relationships among morphologically and geographically remote brown trout populations across western Europe, we ...
