Statistical validation of financial time series via visibility graph
Matteo Serafino, Andrea Gabrielli, Guido Caldarelli +1
Statistical physics of complex systems exploits network theory not only to model, but also to effectively extract information from many dynamical real-world systems. A pivotal case…
From Ecology to Finance (and Back?): Recent Advancements in the Analysis of Bipartite Networks
Mika J. Straka, Guido Caldarelli, Tiziano Squartini +1
Bipartite networks provide an insightful representation of many systems, ranging from mutualistic networks of species interactions to investment networks in finance. The analysis o…
Tackling information asymmetry in networks: a new entropy-based ranking index
Paolo Barucca, Guido Caldarelli, Tiziano Squartini
Information is a valuable asset for agents in socio-economic systems, a significant part of the information being entailed into the very network of connections between agents. The…
Critical field-exponents for secure message-passing in modular networks
Louis M. Shekhtman, Michael M. Danziger, Ivan Bonamassa +4
We study secure message-passing in the presence of multiple adversaries in modular networks. We assume a dominant fraction of nodes in each module have the same vulnerability, i.e.…
Beyond the network of plants volatile organic compounds
Gianna Vivaldo, Elisa Masi, Cosimo Taiti +2
Plants emission of volatile organic compounds (VOCs) is involved in a wide class of ecological functions, as VOCs play a crucial role in plants interactions with biotic and abiotic…
Blockchain Inefficiency in the Bitcoin Peers Network
Giuseppe Pappalardo, T. Di Matteo, Guido Caldarelli +1
We investigate Bitcoin network monitoring the dynamics of blocks and transactions. We unveil that 43\% of the transactions are still not included in the Blockchain after 1h from th…
Grand canonical validation of the bipartite International Trade Network
Mika J. Straka, Guido Caldarelli, Fabio Saracco
Devising strategies for economic development in a globally competitive landscape requires a solid and unbiased understanding of countries technological advancements and similaritie…
Bayesian Networks Analysis of Malocclusion Data
Marco Scutari, Pietro Auconi, Guido Caldarelli +1
In this paper we use Bayesian networks to determine and visualise the interactions among various Class III malocclusion maxillofacial features during growth and treatment. We start…
Organization and hierarchy of the human functional brain network lead to a chain-like core
Rossana Mastrandrea, Andrea Gabrielli, Fabrizio Piras +3
The brain is a paradigmatic example of a complex system as its functionality emerges as a global property of local mesoscopic and microscopic interactions. Complex network theory a…
