The ideal test for the divergence of a series [PDF]

, 2023
We generalize the classical Olivier's theorem which says that for any convergent series $\sum_n a_n$ with positive nonincreasing real terms the sequence $(n a_n)$ tends to zero.

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

Summability characterizations of positive sequences

, 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

Spectral analysis ofmultifractional LRD functional time series [PDF]

, 2022
Long Range Dependence (LRD) in functional sequences is characterized in the spectral domain under suitable conditions. Particularly, multifractionally integrated functional autoregressive moving averages processes can be introduced in this framework ...

Series of Real Numbers [PDF]

, 2017
Ovaj zavšni rad sadrži osnovna svojstva i rezultate koji se odnose na redove realnih brojeva. Najprije se upoznajemo sa samom definicijom niza realnih brojeva i njegovim svojstvima. To je osnova za defniranje reda realnih brojeva.

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 ...

BEAST: Bayesian evolutionary analysis by sampling trees [PDF]

, 2007
Background The evolutionary analysis of molecular sequence variation is a statistical enterprise. This is reflected in the increased use of probabilistic models for phylogenetic inference, multiple sequence alignment, and molecular population genetics ...

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).

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
