Activity networks determine project performance
Alexei Vazquez, Iacopo Pozzana, Georgios Kalogridis +1
Projects are characterised by activity networks with a critical path, a sequence of activities from start to end, that must be finished on time to complete the project on time. Wat…
Spreading of performance fluctuations on real-world project networks
Iacopo Pozzana, Christos Ellinas, Georgios Kalogridis +1
Understanding the role of individual nodes is a key challenge in the study of spreading processes on networks. In this work we propose a novel metric, the reachability-heterogeneit…
Network-based indicators of Bitcoin bubbles
Alexandre Bovet, Carlo Campajola, Jorge F. Lazo +7
The functioning of the cryptocurrency Bitcoin relies on the open availability of the entire history of its transactions. This makes it a particularly interesting socio-economic sys…
Measuring bot and human behavioral dynamics
Iacopo Pozzana, Emilio Ferrara
Bots, social media accounts controlled by software rather than by humans, have recently been under the spotlight for their association with various forms of online manipulation. To…
Epidemic Spreading on Activity-Driven Networks with Attractiveness
Iacopo Pozzana, Kaiyuan Sun, Nicola Perra
We study SIS epidemic spreading processes unfolding on a recent generalisation of the activity-driven modelling framework. In this model of time-varying networks each node is descr…
The entanglement or separability of mixed quantum states as a matter of the choice of observables
Iacopo Pozzana
In quantum systems, entanglement corresponds to nonclassical correlation of nonlocal observables. Thus, entanglement (or, to the contrary, separability) of a given quantum state is…
