Stochasticity directs adaptive evolution toward nonequilibrium evolutionary attractors

recommendations! Published in 2022 at "Ecology"

DOI: 10.1002/ecy.3873

Abstract: Abstract Stochastic processes such as genetic drift may hinder adaptation, but the effect of such stochasticity on evolution via its effect on ecological dynamics is poorly understood. Here we evaluate patterns of adaptation in a… read more here.

recommendations! Published in 2025 at "GeroScience"

DOI: 10.1007/s11357-025-01673-y

Abstract: Aging is characterized by extensive variability in the onset of morbidity and mortality, even in genetically identical populations with carefully controlled environments. This points to the important role stochasticity plays in shaping the divergent aging… read more here.

DOI: 10.1016/j.aop.2016.11.004

Abstract: Markov dynamics constitute one of the most fundamental models of random motion between the states of a system of interest. Markov dynamics have diverse applications in many fields of science and engineering, and are particularly… read more here.

DOI: 10.1016/j.ifacol.2020.12.1170

Abstract: Abstract Stochastic fluctuations (noise) are a fundamental characteristic of protein production. In this work, we explore how these fluctuations can originate from the stochasticity on division events. Here we consider the classical gene expression model… read more here.

DOI: 10.1021/acs.nanolett.4c00184

Abstract: Vanadium dioxide (VO2) microresistors exhibit resistive switching above a certain threshold voltage, allowing them to emulate neurons in neuromorphic systems. However, such devices present intrinsic cycle-to-cycle variations in their resistances and threshold voltages, which can… read more here.

DOI: 10.1038/s41598-017-04596-7

Abstract: The cellular behaviors under the control of genetic circuits are subject to stochastic fluctuations, or noise. The stochasticity in gene regulation, far from a nuisance, has been gradually appreciated for its unusual function in cellular… read more here.

recommendations! Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/staa853

Abstract: A very large dynamic range with simultaneous capture of both large and small scales in the simulations of cosmic structures is required for correct modelling of many cosmological phenomena, particularly at high redshift. This is… read more here.

Effects of stochasticity on the length and behaviour of ecological transients

recommendations! Published in 2021 at "Journal of the Royal Society Interface"

DOI: 10.1098/rsif.2021.0257

Abstract: There is a growing recognition that ecological systems can spend extended periods of time far away from an asymptotic state, and that ecological understanding will therefore require a deeper appreciation for how long ecological transients… read more here.

recommendations! Published in 2024 at "IEEE Transactions on Circuits and Systems I: Regular Papers"

DOI: 10.1109/tcsi.2024.3470318

Abstract: In this paper, we study the stochastic state trajectory and conductance distributions of memristors under periodic pulse excitation. Our results, backed by experimental evidence, reveal that practical memristors exhibit a $1/f^{2}$ Brownian noise power spectrum.… read more here.

Recent exposure to environmental stochasticity does not determine the demographic resilience of natural populations.

recommendations! Published in 2023 at "Ecology letters"

DOI: 10.1111/ele.14234

Abstract: Escalating climatic and anthropogenic pressures expose ecosystems worldwide to increasingly stochastic environments. Yet, our ability to forecast the responses of natural populations to this increased environmental stochasticity is impeded by a limited understanding of how… read more here.

DOI: 10.1186/s40168-018-0409-4

Abstract: BackgroundThe relative importance of stochasticity versus determinism in soil bacterial communities is unclear, as are the possible influences that alter the balance between these. Here, we investigated the influence of spatial scale on the relative… read more here.
