Rates of cultural change and patterns of cultural accumulation in stochastic models of social transmission [0.03%]
基于社会传播的随机模型中的文化变化率和文化积累模式
Kenichi Aoki,Laurent Lehmann,Marcus W Feldman
Kenichi Aoki
Cultural variation in a population is affected by the rate of occurrence of cultural innovations, whether such innovations are preferred or eschewed, how they are transmitted between individuals in the population, and the size of the popula...
Importance sampling for Lambda-coalescents in the infinitely many sites model [0.03%]
无限位点模型中重要性抽样在Lambda-凝聚过程中的应用

Matthias Birkner
We present and discuss new importance sampling schemes for the approximate computation of the sample probability of observed genetic types in the infinitely many sites model from population genetics. More specifically, we extend the 'classi...
Inference on the strength of balancing selection for epistatically interacting loci [0.03%]
上位性相互作用位点平衡选择强度的推理

Erkan Ozge Buzbas
Existing inference methods for estimating the strength of balancing selection in multi-locus genotypes rely on the assumption that there are no epistatic interactions between loci. Complex systems in which balancing selection is prevalent, ...

We generalize a recently introduced graphical framework to compute the probability that haplotypes or genotypes of two individuals drawn from a finite, subdivided population match. As in the previous work, we assume an infinite-alleles mode...
A mathematical model for progression and heterogeneity in colorectal cancer dynamics [0.03%]
结直肠癌动态中的进展和异质性数学模型
Marcello Delitala,Tommaso Lorenzi
Marcello Delitala
This paper deals with the development of a mathematical model that describes cancer dynamics at the cellular scale. The selected case study concerns colon and rectum cancer, which originates in colorectal crypts. Cells inside the crypts are...
Effects of genetic architecture on the evolution of assortative mating under frequency-dependent disruptive selection [0.03%]
基因结构对频率依赖性离散选择下 assortative mating 进化的影响研究
Agnes Rettelbach,Joachim Hermisson,Ulf Dieckmann et al.
Agnes Rettelbach et al.
We consider a model of sympatric speciation due to frequency-dependent competition, in which it was previously assumed that the evolving traits have a very simple genetic architecture. In the present study, we numerically analyze the conseq...
The number of equilibria in the diallelic Levene model with multiple demes [0.03%]
具多个小生境的二等位基因利文模式下的平衡点个数
Sebastian Novak
Sebastian Novak
The Levene model is the simplest mathematical model to describe the evolution of gene frequencies in spatially subdivided populations. It provides insight into how locally varying selection promotes a population's genetic diversity. Despite...
Beyond diffusion: Modelling local and long-distance dispersal for organisms exhibiting intensive and extensive search modes [0.03%]
超越扩散：模拟生物体密集和广泛搜索模式下的局部和长距离传播行为
R C Tyson,J B Wilson,W D Lane
R C Tyson
The distribution of foragers on the landscape has important consequences to, for example, the spread rate of an invasive species or the outcrossing levels between neighbouring crops. Since forager distribution can be difficult to measure di...
Properties of Weir and Cockerham's Fst estimators and associated bootstrap confidence intervals [0.03%]
Weir-Cockerham Fst估计量及其相关的自助置信区间性质
Sivan Leviyang,Matthew B Hamilton
Sivan Leviyang
Weir and Cockerham introduced single locus and multiloci F(st) estimators for the parameter θ. These estimators are commonly used, but little beyond their bias and variance is known. In this work, we develop formulas that allow us to descr...
Adaptive evolutionary walks require neutral intermediates in RNA fitness landscapes [0.03%]
自适应进化在RNA适应度景观中需要中性中间体
Mark D Rendel
Mark D Rendel
In RNA fitness landscapes with interconnected networks of neutral mutations, neutral precursor mutations can play an important role in facilitating the accessibility of epistatic adaptive mutant combinations. I use an exhaustively surveyed ...
