Re-ignition of multi-species soot clouds in building fires

open access: yesReaktor, 2017
The re-ignition potential of multi-species soot clouds in building fires were investigated  based on their extinction characteristics. The investigation was carried out theoretically using the adaptation of Semenov`s thermal explotion theory.

Habitat loss, dispersal, and the probability of extinction of tree species [PDF]

open access: yesCommunicative & Integrative Biology, 2008
Ecological studies show that species not equally decline following habitat destruction, and suggest that underlying biological processes, such as dispersal type, might be determining the ecological sensitivity of species to habitat loss. There is, however, uncertainty as to how these mechanisms scale up to large scales and generalize across ecosystem ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Stochastic models for the Trojan Y-Chromosome eradication strategy of an invasive species

open access: yesJournal of Biological Dynamics, 2016
The Trojan Y-Chromosome (TYC) strategy, an autocidal genetic biocontrol method, has been proposed to eliminate invasive alien species. In this work, we develop a Markov jump process model for this strategy, and we verify that there is a positive ...

A Stochastic Model of East Coast Fever Incorporating a Wildlife–Livestock Interface

open access: yesMathematics
East Coast Fever (ECF) causes approximately one million livestock deaths annually in sub-Saharan Africa, posing a significant threat to livestock. The wildlife–livestock interface complicates disease management, as wildlife serve as reservoirs.

Discounting and Consumption Over an Uncertain Horizon: Draw-Down Plans for Family Trusts [PDF]

open access: yes
Individuals, endowments and trusts face uncertain lifetimes. When the planning horizon of an entity is stochastic and Pareto distributed, hyperbolic discounting and time-varying consumption rates are optimal. We derive expressions for the optimal rate of

Dynamic phenomena arising from an extended Core Group model

open access: yes, 2009
In order to obtain a reasonably accurate model for the spread of a particular infectious disease through a population, it may be necessary for this model to possess some degree of structural complexity.

Probability of Mitochondrial Lineage Extinction in Female Offspring, Modern and Paleolithic: Branching Process Analysis

open access: yes, 2018
We evaluate the probability of extinction of the female offspring of two populations of women: the one Paleolithic, the other that of Italy today. In both cases it is assumed that possible extinction arises exclusively on account of limitations in the ...

Extinction times in multitype Markov branching processes [PDF]

open access: yes, 2009
In this paper, a distributional approximation to the time to extinction in a subcritical continuous-time Markov branching process is derived. A limit theorem for this distribution is established and the error in the approximation is quantified.
