Critical Transition Theory Shows Flickering in Heart Before Atrial Fibrillation

Atrial fibrillation ranks among the most common heart conditions, and episodes are difficult to predict. Researchers have proposed a way to define cardiac state and have studied the dynamics before the cardiac rhythm changes from normal sinus to AF rhythm and vice versa. The work, appearing in Chaos and based on critical transition theory, looks to provide an early warning for those with paroxysmal atrial fibrillation with potential implications for future wearable devices.

Correlations in COVID-19 Growth Point to Universal Strategies for Slowing Spread

Many months since the first COVID-19 outbreak, countries continue to explore solutions to manage the spread of the virus. Chaos theory researchers analyzed the growth of confirmed cases across four continents to better characterize the spread and examine which strategies are effective in reducing it, and their results, published in Chaos, found the virus commonly grows along a power law curve.
