On level crossings for a general class of piecewise-deterministic Markov processes [PDF]

, 2007
We consider a piecewise-deterministic Markov process governed by a jump intensity function, a rate function that determines the behaviour between jumps, and a stochastic kernel describing the conditional distribution of jump sizes.

Assembly mechanisms, not species pool, shape β-diversity of soil methanotrophic communities in steppes of China

Frontiers in Microbiology
IntroductionOne of the central aims in ecology is elucidating the mechanisms that shape community diversity. While biodiversity patterns across geographical gradients are often attributed both to local assembly processes and regional species pools, the ...

Higher genotypic diversity and distinct assembly mechanism of free-living Symbiodiniaceae assemblages than sympatric coral-endosymbiotic assemblages in a tropical coral reef

Microbiology Spectrum
While in hospite Symbiodiniaceae dinoflagellates are essential for coral health, ambient free-living counterparts are crucial for coral recruitment and resilience.

On Mean Field Convergence and Stationary Regime [PDF]

, 2011
Assume that a family of stochastic processes on some Polish space $E$ converges to a deterministic process; the convergence is in distribution (hence in probability) at every fixed point in time.

Aboveground and belowground arthropods experience different relative influences of stochastic versus deterministic community assembly processes following disturbance [PDF]

PeerJ, 2016
Background Understanding patterns of biodiversity is a longstanding challenge in ecology. Similar to other biotic groups, arthropod community structure can be shaped by deterministic and stochastic processes, with limited understanding of what moderates ...

Monte Carlo Filtering of Piecewise Deterministic Processes [PDF]

Journal of Computational and Graphical Statistics, 2011
We present efficient Monte Carlo algorithms for performing Bayesian inference in a broad class of models: those in which the distributions of interest may be represented by\ud time marginals of continuous-time jump processes conditional on a realisation of some noisy observation sequence.

How Does Extreme Drought Affect Phytoplankton Community Assembly in Aquatic Reserves? A Study from the Confluence of Poyang Lake and Yangtze River, China

Diversity
Extreme drought events, intensified by climate change, critically threaten aquatic ecosystem stability by restructuring phytoplankton communities. However, the mechanisms underlying drought-driven community assembly remain poorly understood.

Homomorphism between AOMRC and Hoare Model of Deterministic Reconfiguration Processes in Reconfigurable Computing Systems [PDF]

Scientific Annals of Computer Science, 2007
In this paper, the notion of aspect-oriented modular reconfigurable computing (AOMRC) is introduced, CSP-based behaviors of AOMRC are approached by developing a model of AOMRC and constructing a Hoare model of deterministic reconfiguration processes ...

Forest Soil Fungal Community Elevational Distribution Pattern and Their Ecological Assembly Processes

Frontiers in Microbiology, 2019
Soil fungi play vital roles in natural ecosystems, however, their community distribution patterns along different environmental gradients and ecological assembly processes remain unclear.

Numerical methods for piecewise deterministic Markov processes with boundary

ESAIM: Proceedings and Surveys, 2014
In this paper is described the general aspect of a numerical method for piecewise deterministic Markov processes with boundary. Under very natural hypotheses, a crucial result about uniqueness of solution of a generalized Kolmogorov ...
