Early Warning Signals (EWS) have generated much excitement for their potential to anticipate transitions in various systems, ranging from climate change in ecology to disease staging in medicine. EWS hold particular promise for bifurcations, a transition mechanism in which a smooth, gradual change in...

However, the degree to which theoretical EWS predictions are supported in empirical systems remains unclear. The goal of this ...
prospectively detecting shifts from a healthy towards a symptomatic state has remained unattainable. A complex systems perspective on psychopathology implies that such symptom shifts may be foreseen by generic indicators of instability, or early warning signals (EWS). EWS include, for instance, increasing...
are an outstanding example of past abrupt climate transitions. Their physical cause remains debated, and previous research indicated that they are not preceded by classical early-warning signals (EWS). Subsequent research hypothesized that the DO events ...

A complex systems perspective on psychopathology implies that such symptom shifts may be foreseen by generic indicators of instability, or early warning signals (EWS). EWS include, for instance, increasing variability, covariance, and autocorrelation in momentary affective states—of which the latter ...
New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study, led by the University of Bristol, found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and policy...
There have been many studies about leading indicators of future economic crises, based on multiple indicators called Early Warning Systems (EWS). In the recent years, there has been a strong divergence between the European countries regarding national competitiveness and resilience to the recent crisis...
Early-warning signals (EWS) have been successfully employed to predict transitions in research fields such as biology, ecology, and psychiatry. The predictive properties of EWS might aid in foreseeing transitions in mood episodes (i.e. recurrent episodes of mania and depression) in bipolar disorder...
22Altmetric Metrics Abstract Early warning signals (EWSs) offer the hope that patterns observed in data can predict the future states of ecological systems. While a large body of research identifies such signals prior to the collapse of populations, the prediction that such signals should also be...
