Coevolutionary Dynamics: From Finite to Infinite Populations [PDF]

open access: yes, 2005
Traditionally, frequency dependent evolutionary dynamics is described by deterministic replicator dynamics assuming implicitly infinite population sizes.

Exploring the driving factors of bryophyte assemblage distribution patterns in Tibet

open access: yesFrontiers in Ecology and Evolution
Plant communities are complex systems shaped by a combination of deterministic and stochastic ecological processes. Bryophytes are an essential component of plant diversity in natural ecosystems, yet our understanding of their community ecology needs to ...

Microbial Communities in a Serpentinizing Aquifer Are Assembled through Strong Concurrent Dispersal Limitation and Selection

open access: yesmSystems, 2021
Microbial communities existing under extreme or stressful conditions have long been thought to be structured primarily by deterministic processes. The application of macroecology theory and modeling to microbial communities in recent years has spurred ...

Fluctuations and stability in front propagation [PDF]

open access: yes, 2010
Propagating fronts arising from bistable reaction-diffusion equations are a purely deterministic effect. Stochastic reaction-diffusion processes also show front propagation which coincides with the deterministic effect in the limit of small fluctuations (

Jump processes with deterministic and stochastic controls [PDF]

open access: yesPhysical Review E, 2019
We consider the dynamics of a 1D system evolving according to a deterministic drift and randomly forced by two types of jumps processes, one representing an external, uncontrolled forcing and the other one a control that instantaneously resets the system according to specified protocols (either deterministic or stochastic). We develop a general theory,

Deterministic Drivers of Microbial Community Succession in Nongxiang Daqu Fermentation: Fungi Exhibit Stronger Environmental Selection Imprints than Bacteria

open access: yesFermentation
Microbial communities are the fundamental determinants of Nongxiang Daqu quality. In this study, we systematically investigated the assembly and succession mechanisms of microbial communities during Nongxiang Daqu fermentation.

Assessment of stochastic and deterministic models of 6304 quasar lightcurves from SDSS Stripe 82 [PDF]

open access: yes, 2013
The optical light curves of many quasars show variations of tenths of a magnitude or more on time scales of months to years. This variation often cannot be described well by a simple deterministic model.

Impacts of fertilization methods on Salvia miltiorrhiza quality and characteristics of the epiphytic microbial community

open access: yesFrontiers in Plant Science
Plant epiphytic microorganisms have established a unique symbiotic relationship with plants, which has a significant impact on their growth, immune defense, and environmental adaptation.

Average Continuous Control of Piecewise Deterministic Markov Processes

open access: yes, 2008
This paper deals with the long run average continuous control problem of piecewise deterministic Markov processes (PDMP's) taking values in a general Borel space and with compact action space depending on the state variable.

A time series analysis of U.K. construction and real estate indices [PDF]

open access: yes, 2013
This study assess the nonlinear behavior of U.K. Construction and Real Estate indices. Standard unit root tests show that both time series are I(1) processes.
