  • 4 June 2019
In this paper, we study the extinction time of logistic branching processes which are perturbed by an independent random environment driven by a Brownian motion. Our arguments use a Lamperti-type…

Influence of a spatial structure on the long time behavior of a competitive Lotka-Volterra type system
To describe population dynamics, it is crucial to take into account jointly evolution mechanisms and spatial motion. However, the models which include these both aspects, are not still…

Monte Carlo methods for linear and non-linear Poisson-Boltzmann equation
TLDR
A new probabilistic interpretation of the nonlinear Poisson-Boltzmann PDE is proved, that also requires efficient computational geometry algorithms, and is compared with the deterministic solver APBS.

Extinction and coming down from infinity of CB-processes with competition in a L\'evy environment
In this note, we are interested on the event of extinction and the property of coming down from infinity of continuous state branching (or CB for short) processes with competition in a Levy…
A stochastic model for speciation by mating preferences
TLDR
A stochastic model of population where individuals, with type a or A, are equivalent from ecological, demographical and spatial points of view, and differ only by their mating preference, showing that mating preferences by themselves, even if they are very small, are enough to entail reproductive isolation between patches.

A multi-scale eco-evolutionary model of cooperation reveals how microbial adaptation influences soil decomposition
TLDR
A multi-scale model to explain the evolution of microbial cooperation driving the decomposition of soil organic matter shows that the evolutionary stability of decomposition depends on a combination of local extinctions, microbial dispersal, and limited soil diffusivity.

127 Preclinical evaluation of NKX019, a CD19-targeting CAR NK Cell
TLDR
A highly potent CD19 -directed CAR NK cell therapy with an extended in vivo half-life aimed at killing CD19-expressing target, NKX019, which exhibited advantages compared to CAR19+ T cells including faster cytotoxic kinetics and limited production of cytokines associated with CRS.

Convergence of an infinite dimensional stochastic process to a spatially structured trait substitution sequence
We consider an individual-based spatially structured population for Darwinian evolution in an asexual population. The individuals move randomly on a bounded continuous space according to a reflected…

Assortative mating driving spatial divergence of mating trait in diploid species: how dominance influences population differentiation?
TLDR
The results highlight that heterozygotes' behaviour has a strong impact on population differentiation and stress out the need of diploid models of differentiation and speciation driven by natural and sexual selection.
