Early warning signals for loss of control in complex systems. [PDF]
Proc Natl Acad Sci U S AMaintaining stability in feedback systems, from aircraft and autonomous robots to biological and physiological systems, relies on monitoring their behavior and continuously adjusting their inputs. Incremental damage can make such control fragile.

How one might miss early warning signals of critical transitions in time series data: A systematic study of two major currency pairs. [PDF]
PLoS ONE, 2018 There is growing interest in the use of critical slowing down and critical fluctuations as early warning signals for critical transitions in different complex systems. However, while some studies found them effective, others found the opposite.

In Defense of Early Warning Signals [PDF]
SSRN Electronic Journal, 2013 The 2008 financial crisis has rekindled interest in the issue of early warning signals (EWS) of financial distress. It has also triggered renewed interest in the literature on currency crises, with many countries, especially among emerging market economies, experiencing severe exchange market pressure.

Flickering as an early warning signal [PDF]
Theoretical Ecology, 2013 Most work on generic early warning signals for critical transitions focuses on indicators of the phenomenon of critical slowing down that precedes a range of catastrophic bifurcation points. However, in highly stochastic environments, systems will tend to shift to alternative basins of attraction already far from such bifurcation points.

Early‐Warning Signals for Critical Temperature Transitions
Geophysical Research Letters, 2020 Critical transitions of the state variable (temperature) in dynamic climate systems often lead to catastrophic consequence, whereas the effort to reverse the transitions usually lags behind.

Hidden early-warning signals in scale-free networks. [PDF]
PLoS ONE, 2017 Critical transitions of complex systems can often be predicted by so-called early-warning signals (EWS). In some cases, however, such signals cannot be detected although a critical transition is imminent. Observing a relation of EWS-detectability and the

Warning signals and predator-prey coevolution
, 2004 Theories of the evolution of warning signals are typically expressed using analytic and computational models, most of which attribute aspects of predator psychology as the key factors facilitating the evolution of warning signals.

Atmosphere, 2023 This paper assessed the impacts of environmental smog early-warning signals on road traffic deaths. For an accurate assessment, we used the daily traffic death data from 2016 to 2020 in 295 Chinese cities and constructed a rigorous Regression ...

Scientific Reports, 2021 We are concerned with the issue of detecting changes and their signs from a data stream. For example, when given time series of COVID-19 cases in a region, we may raise early warning signals of an epidemic by detecting signs of changes in the data.
