Genotype By Environment Interaction in Shoot Branching [PDF]

open access: yes, 2012
Plant development is highly plastic, allowing plants to adapt to constant changes in environmental conditions. An excellent example of developmental plasticity is shoot branching.

On a Class of Time-Fractional Continuous-State Branching Processes [PDF]

open access: yes, 2017
We propose a class of non-Markov population models with continuous or discrete state space via a limiting procedure involving sequences of rescaled and randomly time-changed Galton\tire Watson processes. The class includes as specific cases the classical

Timed Branching Processes [PDF]

open access: yes2010 Seventh International Conference on the Quantitative Evaluation of Systems, 2010
We study Timed Branching Processes (TBPs), a natural extension of (multitype) Branching Processes (BPs) where each entity is equipped with a finite set of private continuous variables, called clocks. Clocks grow uniformly with the same rate and using them various timing constraints can be imposed on the branching rules of the system, e.g.

Branching in the landscape of possibilities [PDF]

open access: yes, 2011
The metaphor of a branching tree of future possibilities has a number of important philosophical and logical uses. In this paper we trace this metaphor through some of its uses and argue that the metaphor works the same way in physics as in philosophy ...

On the Inclusion of Self Regulating Branching Processes in the Working Paradigm of Evolutionary and Population Genetics

open access: yesFrontiers in Genetics, 2013
The principal goal of this methodological paper is to suggest to a generalaudience in the genetics community that the consideration of recentdevelopments of self regulating branching processes may lead to thepossibility of including this class of ...

Critical branching processes in a sparse random environment

open access: yesModern Stochastics: Theory and Applications, 2023
We introduce a branching process in a sparse random environment as an intermediate model between a Galton–Watson process and a branching process in a random environment.

In the Garden of Branching Processes

open access: yesSIAM Review, 2004
The review article summarizes the theory of multitype branching processes in continuous time. The process includes immigration which is modelled as a Poisson stream of immigrant particles. Marked Poisson processes and Campbell's formulae are applied. The extinction probability is calculated.

The Width of Galton-Watson Trees Conditioned by the Size [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2004
It is proved that the moments of the width of Galton-Watson trees of size n and with offspring variance σ ^2 are asymptotically given by (σ √n)^pm_p where m_p are the moments of the maximum of the local time of a standard scaled Brownian excursion.

On Neutron Branching Processes

open access: yesPublications of the Research Institute for Mathematical Sciences, 1971
A statistical theory of the neutron transport process has been discussed by Harris [[I] and Mullikin Q7J. They considered the neutron population by generation rather than in real time and formulate them as a discretetime branching process. In this paper, we will formulate the neutron transport process as a continuous time branching process and study ...
