Activity cascades are found in many complex systems. In the cortex, they arise in the form of
neuronal avalanches that capture ongoing and evoked neuronal activities at many spatial …

The scale-free nature of daily human activity has been observed in different aspects;
however, the description of its spectral characteristics is incomplete. General findings are …

Prolonged periods of sleep restriction seem to be common in the contemporary world. Sleep
loss causes perturbations of circadian rhythmicity and degradation of waking alertness as …

To find useful work to do for their colony, individual eusocial animals have to move,
somehow staying attentive to relevant social information. Recent research on individual …

Physical activity is disrupted in many psychiatric disorders. Advances in everyday
technologies–such as accelerometers in smart phones–opens exciting possibilities for non …

Several years ago, in the context of the physics of hysteresis in magnetic materials, a simple
stochastic model has been introduced: the ABBM model. Later, the ABBM model has been …

Many materials are produced, processed and stored as grains, while granularity of matter
can be crucial in triggering potentially catastrophic geological events like landslides …

The healthcare process generates a vast quantity of data. Exploitation and analysis of such
material might lead discoveries and potentially improve the clinical activity. Over the last …

In this article, we study the dynamics of marking in football matches. To do this, we survey
and analyze a database containing the trajectories of players from both teams on the field of …

The motion of social insects is often used as a paradigmatic example of complex adaptive
dynamics arising from decentralized individual behaviour. In this paper, we revisit the topic …
