Self-pulsing dynamics in a cavity soliton laser [PDF]
, 2010 The dynamics of a broad-area vertical-cavity surface-emitting laser (VCSEL) with frequency-selective feedback supporting bistable spatial solitons is analyzed experimentally and theoretically. The transient dynamics of a switch-on of a soliton induced by

Selective sweep probabilities in spatially expanding populations
, 2023 AbstractEvolution during range expansions shapes biological systems from microbial communities and tumours up to invasive species. A fundamental question is whether, when a beneficial mutation arises during a range expansion, it will evade clonal interference and sweep through the population to fixation.

Genome-wide selective sweeps and gene-specific sweeps in natural bacterial populations [PDF]
The ISME Journal, 2016 Abstract Multiple models describe the formation and evolution of distinct microbial phylogenetic groups. These evolutionary models make different predictions regarding how adaptive alleles spread through populations and how genetic diversity is maintained.

Identification of selection signatures in livestock species
Genetics and Molecular Biology, 2014 The identification of regions that have undergone selection is one of the principal goals of theoretical and applied evolutionary genetics. Such studies can also provide information about the evolutionary processes involved in shaping genomes, as well as

Genetic Variation in Human Gene Regulatory Factors Uncovers Regulatory Roles in Local Adaptation and Disease [PDF]
, 2019 Differences in gene regulation have been suggested to play essential roles in the evolution of phenotypic changes. Although DNA changes in cis-regulatory elements affect only the regulation of its corresponding gene, variations in gene regulatory factors

The evolutionary genetics of lactase persistence in seven ethnic groups across the Iranian plateau
Human Genomics, 2019 Background The ability to digest dietary lactose is associated with lactase persistence (LP) in the intestinal lumen in human. The genetic basis of LP has been investigated in many populations in the world.

Complex genome evolution in Anopheles coluzzii associated with increased insecticide usage in Mali. [PDF]
, 2015 In certain cases, a species may have access to important genetic variation present in a related species via adaptive introgression. These novel alleles may interact with their new genetic background, resulting in unexpected phenotypes.
