Article Synopsis
- This text discusses the concept of resilience in systems, emphasizing the idea that as a system nears a tipping point, it takes longer to recover from disturbances, which can be measured using indicators like autocorrelation and variance.
- The authors compare two methods for assessing resilience changes: a traditional moving window approach using continuous data versus a burst method that uses high-resolution data collected in short periods.
- The findings suggest that the burst method is more effective in detecting resilience changes, potentially leading to improved monitoring in fields like health and ecology where continuous data collection may be challenging or expensive.
Complex systems ranging from societies to ecological communities and power grids may be viewed as networks of connected elements. Such systems can go through critical transitions driven by an avalanche of contagious change. Here we ask, where in a complex network such a systemic shift is most likely to start.

Biogeochemical fluxes link tropical coastal habitats by exchanging material flows and energy through various natural processes that determine the conditions for life and ecosystem functioning. However, little is known about the seascape-scale implications of anthropogenic disruptions to these linkages.

It has been suggested that the same theory may be used to explain the nature and dynamics of psychiatric disorders, which may come and go with symptoms changing over a lifetime. Here we review evidence for the practical applicability of this theory and its quantitative tools in psychiatry.

- Psychiatric disorders can fluctuate over a person's lifetime, suggesting a need for a new approach to diagnosis and treatment, influenced by dynamical systems theory which looks at complex systems.
- This theory posits that mental health can be viewed as a dynamic property, where a healthy state is resilient, while disorders represent alternative states the system can become trapped in.
- The findings from other complex systems indicate potential new methods for assessing and managing mental health resilience, offering practical applications for psychiatry.
