A Small World of Bad Guys: Investigating the Behavior of Hacker Groups in Cyber-Attacks
Giampiero Giacomello, Antonio Iovanella, Luigi Martino
This paper explores the behaviour of malicious hacker groups operating in cyberspace and how they organize themselves in structured networks. To better understand these groups, the…
Network constraints on the mixing patterns of binary node metadata
Matteo Cinelli, Leto Peel, Antonio Iovanella +1
We consider the network constraints on the bounds of the assortativity coefficient, which measures the tendency of nodes with the same attribute values to be interconnected. The as…
Towards more effective consumer steering via network analysis
Jacopo Arpetti, Antonio Iovanella
Increased data gathering capacity, together with the spread of data analytics techniques, has prompted an unprecedented concentration of information related to the individuals' pre…
Measuring network resilience through connection patterns
Roy Cerqueti, Giovanna Ferraro, Antonio Iovanella
Networks are at the core of modeling many engineering contexts, mainly in the case of infrastructures and communication systems. The resilience of a network, which is the property…
A new measure for community structures through indirect social connections
Roy Cerqueti, Giovanna Ferraro, Antonio Iovanella
Based on an expert systems approach, the issue of community detection can be conceptualized as a clustering model for networks. Building upon this further, community structure can…
Resilience of Core-Periphery Networks in the Case of Rich-Club
Matteo Cinelli, Giovanna Ferraro, Antonio Iovanella
Core-periphery networks are structures that present a set of central and densely connected nodes, namely the core, and a set of non-central and sparsely connected nodes, namely the…
Rich-Club Ordering and the Dyadic Effect: Two Interrelated Phenomena
Matteo Cinelli, Giovanna Ferraro, Antonio Iovanella
Rich-club ordering and the dyadic effect are two phenomena observed in complex networks that are based on the presence of certain substructures composed of specific nodes. Rich-clu…
Structural Bounds on the Dyadic Effect
Matteo Cinelli, Giovanna Ferraro, Antonio Iovanella
In this paper we consider the dyadic effect introduced in complex networks when nodes are distinguished by a binary characteristic. Under these circumstances two independent parame…
Choreography In Inter-Organizational Innovation Networks
Giovanna Ferraro, Antonio Iovanella
This paper introduces the concept of choreography with respect to inter-organizational innovation networks, as they constitute an attractive environment to create innovation in dif…
On the statistical description of the inbound air traffic over Heathrow airport
Maria Virginia Caccavale, Antonio Iovanella, Carlo Lancia +2
We present a model to describe the inbound air traffic over a congested hub. We show that this model gives a very accurate description of the traffic by the comparison of our theor…
Some spin glass ideas applied to the clique problem
Antonio Iovanella, Benedetto Scoppola, Elisabetta Scoppola
In this paper we introduce a new algorithm to study some NP-complete problems. This algorithm is a Markov Chain Monte Carlo (MCMC) inspired by the cavity method developed in the st…
