    Effective design of marine reserves: incorporating alongshore currents, size structure, and uncertainty by Reimer, J

    Published 2013
    “…We then use this approximation to obtain results on extinction using two different approaches, which we can compare to the baseline IBM; the first approach is based on the Central Limit Theorem and provides efficient simulation results, and the second modifies a simple Galton-Watson branching process to include loss outside the reserve area. …”

    Efficient Induction of Syncytiotrophoblast Layer II Cells from Trophoblast Stem Cells by Canonical Wnt Signaling Activation by Dongmei Zhu, Xia Gong, Liyun Miao, Junshun Fang, Jian Zhang

    Published 2017-12-01
    “…Furthermore, HGF-expressing cells lie adjacent to SynT-II cells in developing murine placenta, suggesting that HGF/c-MET signaling plays a critical role in SynT-II cell morphogenesis during the labyrinth branching process. The availability of SynT-II cells in vitro will facilitate molecular understanding of labyrinth layer development. : Zhu and colleagues successfully induce mouse syncytiotrophoblast (SynT) layer II cells from trophoblast stem cells by activation of canonical Wnt signaling. …”

    The fate of recessive deleterious or overdominant mutations near mating-type loci under partial selfing by Tezenas, Emilie, Giraud, Tatiana, Véber, Amandine, Billiard, Sylvain

    Published 2023-01-01
    “…In particular, under what conditions deleterious mutations are likely to be maintained for long enough near mating-compatibility genes remains to be evaluated, especially under selfing, which generally increases the purging rate of deleterious mutations. Using a branching process approximation, we studied the fate of a new deleterious or overdominant mutation in a diploid population, considering a locus carrying two permanently heterozygous mating-type alleles, and a partially linked locus at which the mutation appears. …”

    Growth of Levy trees by Duquesne, T, Winkel, M

    Published 2005
    “…We construct random locally compact real trees called Levy trees that are the genealogical trees associated with continuous-state branching processes. More precisely, we define a growing family of discrete Galton-Watson trees with i.i.d. exponential branch lengths that is consistent under Bernoulli percolation on leaves; we define the Levy tree as the limit of this growing family with respect to the Gromov-Hausdorff topology on metric spaces. …”
