Summability characterizations of positive sequences [PDF]
, 2022 In this paper, we propose extensions for the classical Kummer test, which isa very far-reaching criterion that provides sufficient and necessary conditionsfor convergence and divergence of series of positive terms. Furthermore, wepresent and discuss some

Whole-genome comparison of two Campylobacter jejuni isolates of the same sequence type reveals multiple loci of different ancestral lineage [PDF]
, 2011 Campylobacter jejuni ST-474 is the most important human enteric pathogen in New Zealand, and yet this genotype is rarely found elsewhere in the world. Insight into the evolution of this organism was gained by a whole genome comparison of two ST-474, flaA

Poisson inverse problems [PDF]
, 2006 In this paper we focus on nonparametric estimators in inverse problems for Poisson processes involving the use of wavelet decompositions. Adopting an adaptive wavelet Galerkin discretization, we find that our method combines the well-known theoretical ...

Inferring kangaroo phylogeny from incongruent nuclear and mitochondrial genes [PDF]
, 2013 The marsupial genus Macropus includes three subgenera, the familiar large grazing kangaroos and wallaroos of M. (Macropus) and M. (Osphranter), as well as the smaller mixed grazing/browsing wallabies of M. (Notamacropus).

Allozyme and mitochondrial DNA variability within the New Zealand damselfly genera Xanthocnemis, Austrolestes, and Ischnura (Odonata) [PDF]
, 2007 We collected larval damselflies from 17 sites in the North, South and Chatham Islands, and tested the hypotheses that: (1) genetic markers (e.g., allozymes, mtDNA) would successfully ¬discriminate taxa; and (2) the dispersal capabilities of adult ...

Convergence and plasticity in the adaptive radiation of cichlid fishes [PDF]
, 2013 Ever since Charles Darwin and Alfred Wallace (1858) propelled our understanding about the importance of natural selection in the transformation of species, researchers endeavoured to use this intellectual foundation to explain larger patterns of ...
