Effective population size for culturally evolving traits.
PLoS Computational Biology, 2022 Population size has long been considered an important driver of cultural diversity and complexity. Results from population genetics, however, demonstrate that in populations with complex demographic structure or mode of inheritance, it is not the census ...

Ancestry-specific recent effective population size in the Americas. [PDF]
PLoS Genetics, 2018 Populations change in size over time due to factors such as population growth, migration, bottleneck events, natural disasters, and disease. The historical effective size of a population affects the power and resolution of genetic association studies ...

Estimating effective population size using RADseq: Effects of SNP selection and sample size
Ecology and Evolution, 2020 Effective population size (Ne) is a key parameter of population genetics. However, Ne remains challenging to estimate for natural populations as several factors are likely to bias estimates.

Metapopulation effective size and conservation genetic goals for the Fennoscandian wolf (Canis lupus) population. [PDF]
Heredity (Edinb), 2016 The Scandinavian wolf population descends from only five individuals, is isolated, highly inbred and exhibits inbreeding depression. To meet international conservation goals, suggestions include managing subdivided wolf populations over Fennoscandia as a

On the eigenvalue effective size of structured populations. [PDF]
J Math Biol, 2015 A general theory is developed for the eigenvalue effective size ($$N_{eE}$$NeE) of structured populations in which a gene with two alleles segregates in discrete time.

Small effective size limits performance in a novel environment. [PDF]
Evol Appl, 2013 Understanding what limits or facilitates species' responses to human‐induced habitat change can provide insight for the control of invasive species and the conservation of small populations, as well as an arena for studying adaptation to realistic novel ...

Presynaptic calcium influx controls neurotransmitter release in part by regulating the effective size of the readily releasable pool. [PDF]
J Neurosci, 2013 The steep calcium dependence of synaptic strength that has been observed at many synapses is thought to reflect a calcium dependence of the probability of vesicular exocytosis (p), with the cooperativity of three to six corresponding to the multiple ...

A Simple and Effective Pruning Approach for Large Language Models [PDF]
International Conference on Learning Representations, 2023 As their size increases, Large Languages Models (LLMs) are natural candidates for network pruning methods: approaches that drop a subset of network weights while striving to preserve performance.

Samples from subdivided populations yield biased estimates of effective size that overestimate the rate of loss of genetic variation. [PDF]
Mol Ecol Resour, 2014 Many empirical studies estimating effective population size apply the temporal method that provides an estimate of the variance effective size through the amount of temporal allele frequency change under the assumption that the study population is ...

Large Language Models are Effective Text Rankers with Pairwise Ranking Prompting [PDF]
NAACL-HLT, 2023 Ranking documents using Large Language Models (LLMs) by directly feeding the query and candidate documents into the prompt is an interesting and practical problem.
