Two-mode geometry controls multiscale organization in bipartite systems
Ottavia Falconi, Giulio Cimini, Pablo Villegas
Many complex systems are organized around complementary roles and naturally described as bipartite networks. Unveiling their multiscale structure presents a fundamental challenge b…
Topology as information: Network effects in corporate lending
Anna Pirogova, Anna Mancini, Tiziano Squartini +1
A central challenge in financial economics is understanding how credit networks form under informational noise. We introduce the concept of topological capital, arguing that banks…
Modeling structure and credit risk of the economy: a multilayer bank-firm network approach
Soumen Majhi, Anna Mancini, Giulio Cimini
Assessing the resilience of the economy requires accounting for its intrinsic multi-layer nature, by assessing for instance how disruptions at the firm level spread through the pro…
Missing links prediction: comparing machine learning with physics-rooted approaches
Francesca Santucci, Giulio Cimini, Tiziano Squartini
An active research line within the broader field of network science is the one concerning link prediction. Close in scope to network reconstruction, link prediction targets specifi…
Block-Fitness Modeling of the Global Air Mobility Network
Giulia Fischetti, Anna Mancini, Giulio Cimini +4
Accurate representations of the World Air Transportation Network (WAN) are fundamental inputs to models of global mobility, epidemic risk, and infrastructure planning. However, hig…
Inferring the Turbulent Breakup of Colloidal Aggregates Using Graph Neural Networks
Michele Buzzicotti, Massimo Cencini, Giulio Cimini +2
Solid aggregates in turbulent suspensions may break under the action of shear stresses. We explore the use of Graph Neural Networks (GNN) to infer aggregate fragmentation once the…
