Since ancient times, scientists have sought to identify precursory signals which might allow the prediction of impending earthquakes or volcanic eruptions.

The addition of stochastic noise to a deterministic dynamical system can induce dramatic qualitative changes in its behaviour. In one counterintuitive effect – termed noise induced order – the addition of noise to an already chaotic system can make its behaviour more orderly and regular.
Dividing things into categories is a human habit, helping us to learn and understand the external world, as well as to share and communicate knowledge.
In nonlinear dynamics, a chimera refers to a dynamical hybrid – a state in a network of identical coupled oscillators exhibiting a mix of both synchronous and asynchronous behaviour.
In most of the developing world, individual wealth tends to increase with city size, making migration an important avenue for poverty reduction.
In 19th-century casinos, most common betting took the form of even-money bets placed on red or black in games such as Roulette. Strategy lay in deciding how much to wager on each bet, and when to quit playing.
Vaccines against the SARS-CoV-2 virus appear, finally, to offer nations around the globe a pathway out of the COVID pandemic. Yet vaccines themselves come with potential risks of side-effects. In the aftermath of some three dozen or so cases of deaths from blood clots in recently vaccinated individuals, a handful of European nations recently paused […]
Before the COVID-19 pandemic, a major source of annoyance for international travelers was flight delays, caused by anything from engineering failures to simple traffic flow issues through the complex network of international airports.
Network scientists rely on random graphs to model the behaviour of complex networks observed in social, technological, and biological systems. One common approach to such network modelling starts by measuring an empirical set of observables, and then builds an ensemble of random graphs to match these features in an average sense.
Over the past few years, extreme value theory (EVT) has increasingly found use in the analysis of dynamical systems, especially to quantify the probabilities of rare events, defined as visits to particular small subsets of the phase space.
