Data-driven identification of reliable sensor species to predict regime shifts in ecological networks [PDF]

Royal Society Open Science, 2020
Signals of critical slowing down are useful for predicting impending transitions in ecosystems. However, in a system with complex interacting components not all components provide the same quality of information to detect system-wide transitions ...

Early Warning Signals of Dry-Wet Transition in China in Recent 60 Years

Gaoyuan qixiang, 2023
In recent years， the dry-wet transition has become more and more frequent.The dry-wet transition is related to the formation of regional flood， drought and other disaster events.It is a hot scientific issue in the current nonlinear dynamics research that

Practical guide to using Kendall’s τ in the context of forecasting critical transitions

Royal Society Open Science, 2022
Recent studies demonstrate that trends in indicators extracted from measured time series can indicate an approach of an impending transition. Kendall’s τ coefficient is often used to study the trend of statistics related to the critical slowing down ...

Investigation of critical slowing down in a bistable S-SEED [PDF]

, 2003
A simulation of S-SEED switching based upon experimental data is developed that includes the effect of critical slowing down. The simulation's accuracy is demonstrated by close agreement with the results from experimental S-SEED switching. The simulation

CRITICAL SLOWING DOWN IN BIOLOGICAL BISTABLE MODELS [PDF]

International Journal of Pure and Apllied Mathematics, 2014
Summary: We investigate both analytically and computationally, the bistable behaviour in some biological mathematical models, namely: spruce budworm infestations, the Thomas reaction model and the activator-inhibitor model of Gierer-Meinhardt. Bistable behaviour is achieved by treating some of the concentration, supply, degradation and reaction rates ...

Critical slowing down theory provides early warning signals for sandstone failure

Frontiers in Earth Science, 2022
The critical point of rock mass transition from stable to unstable states is significant for the prevention and control of rock engineering hazards. This study explored the precursor characteristics of instability in sandstone containing prefabricated ...

Critical Slowing Down in Stochastic Processes. I [PDF]

Progress of Theoretical Physics, 1982
Summary: This series of papers clarifies the physical mechanism of a critical slowing down in stochastic processes. There are three categories, namely (i) deterministic, (ii) marginal and (iii) noise-induced critical slowing downs. In part I, some general aspects of critical slowing down are studied in multiplicative stochastic processes.

Critical slowing down in dynamical systems driven by nonstationary correlated noise

Physical Review Research, 2022
Precursor signals for bifurcation-induced critical transitions have recently gained interest across many research fields. Common indicators, including variance and autocorrelation increases, rely on the dynamical system being driven by white noise. Here,

Non-critical slowing down of photonic condensation [PDF]

, 2019
We investigate the response of a photonic gas interacting with a reservoir of pumped dye-molecules to quenches in the pump power. In addition to the expected dramatic critical slowing down of the equilibration time around phase transitions we find ...
