Theoretical and computational study of the energy dependence of the muon transfer rate from hydrogen to higher-Z gases

, 2014
The recent PSI Lamb shift experiment and the controversy about proton size revived the interest in measuring the hyperfine splitting in muonic hydrogen as an alternative possibility for comparing ordinary and muonic hydrogen spectroscopy data on proton ...

Chemical Composition of the Early Universe

, 2003
A prediction of standard inflationary cosmology is that the elemental composition of the medium out of which the earliest stars and galaxies condensed consisted primarily of hydrogen and helium 4He with small admixtures of deuterium, lithium 7Li, and 3He.

Reliable ABC model choice via random forests

, 2015
Approximate Bayesian computation (ABC) methods provide an elaborate approach to Bayesian inference on complex models, including model choice. Both theoretical arguments and simulation experiments indicate, however, that model posterior probabilities may ...

Modelling the Consequences of Domestication‐Introgression in Wild Populations Using Genetic Markers Under Varying Degrees of Selection

Evolutionary Applications
Introgression of domesticated genomes influences the evolutionary trajectory of wild populations. Genetic markers are used to quantify admixture in wild populations subjected to introgression from non‐native conspecifics.

Genetic origin, admixture and population history of aurochs (Bos primigenius) and primitive European cattle

Heredity, 2016
The domestication of taurine cattle initiated ~10 000 years ago in the Near East from a wild aurochs (Bos primigenius) population followed by their dispersal through migration of agriculturalists to Europe.

Population Genomics in Wild Tomatoes—The Interplay of Divergence and Admixture

Genome Biology and Evolution, 2017
Hybridization between closely related plant species is widespread, but the outcomes of hybridization are not fully understood. This study investigates phylogenetic relationships and the history of hybridization in the wild tomato clade (Solanum sect ...

PSMIX: an R package for population structure inference via maximum likelihood method

BMC Bioinformatics, 2006
Background Inference of population stratification and individual admixture from genetic markers is an integrative part of a study in diverse situations, such as association mapping and evolutionary studies.

Tracing the Origin of the East-West Population Admixture in the Altai Region (Central Asia)

PLoS ONE, 2012
A recent discovery of Iron Age burials (Pazyryk culture) in the Altai Mountains of Mongolia may shed light on the mode and tempo of the generation of the current genetic east-west population admixture in Central Asia. Studies on ancient mitochondrial DNA

Development of a large SNPs resource and a low-density SNP array for brown trout (Salmo trutta) population genetics

BMC Genomics, 2019
Background The brown trout (Salmo trutta) is an economically and ecologically important species for which population genetic monitoring is frequently performed. The most commonly used genetic markers for this species are microsatellites and mitochondrial
