Opinion Dynamics in Financial Markets via Random Networks
We investigate the financial market dynamics by introducing a heterogeneous agent-based opinion formation model.
Community detection and portfolio optimization
Community detection methods can be used to explore the structure of complex systems.
A new look at calendar anomalies: Multifractality and day of the week effect
From the time-dependent multifractal analysis we find that multifractal spectra for Monday returns are much wider than for other days during periods of financial crises.
Impacts of export restrictions on the global personal protective equipment trade network during COVID-19
The threshold model captures the shortage contagion on the global PPE trade network.

Majority-vote model with limited visibility: an investigation into filter bubbles
Here, we introduce a visibility parameter $V$ in the dynamics of the majority-vote model, which equals the probability of an individual ignoring the opinion of each one of its neighbors.

Network resilience
Many systems on our planet are known to shift abruptly and irreversibly from one state to another when they are forced across a "tipping point," such as mass extinctions in ecological networks, cascading failures in infrastructure systems, and social convention changes in human and animal networks.
A Matrix Factorization Model for Hellinger-based Trust Management in Social Internet of Things
We model the SIoT with a flexible bipartite graph (containing two sets of nodes: service providers and service requestors), then build a social network among the service requestor nodes, using the Hellinger distance.
Compressive Closeness in Networks
In such algorithms, a node is allowed only to have local interactions with its immediate neighbors.
