Statistical Characterization of Airplane Delays
Posted on
by
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.

Analytic solution of the two-star model with correlated degrees
Posted on
by
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 […]

Extreme value distributions of observation recurrences
Posted on
by
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.

Localization and Universality of Eigenvectors in Directed Random Graphs
Posted on

Many complex systems including neural networks, ecosystems, physical materials or the World Wide Web involve individual components which interact in large networks.

Quantifying simultaneous innovations in evolutionary medicine
Posted on
by
Many historians see great innovations as emerging from the genius and relentless hard work of individuals, yet attributing innovations to specific individuals is not always straightforward.

A non‐parametric Hawkes process model of primary and secondary accidents on a UK smart motorway
Posted on
by
In the United Kingdom, traffic accidents led to 1782 deaths and 25,484 serious injuries in 2018. In addition to these direct human costs, crashes, collisions and breakdowns also cause severe congestion leading to significant drops in road efficiency. Hence, there is an […]

Epidemic oscillations induced by social network control: the discontinuous case
Posted on
by
The principles of control theory assert that feedback often leads to unstable behaviour and oscillatory dynamics. Examples include engineering systems such as thermostats and steering devices, as well as natural and biological systems.

As centres of human population and civilisation, cities have pushed the boundaries of human productivity and innovation.

Extreme value theory for constrained physical systems
Posted on
by
Many stochastic processes in natural and man-made systems exhibit occasional extreme events which are rare in comparison to usual outcomes. Though infrequent, such events can still carry decisive weight.

Narrative structure of A Song of Ice and Fire creates a fictional world with realistic measures of social complexity
Posted on
by
The global television hit Game of Thrones, first aired in 2011, was inspired by a series of fantasy books written by George R. R. Martin. Since publication in 1996, A Song of Ice and Fire has been translated into more than 45 […]
