Investigation of dynamics of a virus–antivirus model in complex network

Ren, Jianguo; Xu, Yonghong; Liu, Jiming - In: Physica A: Statistical Mechanics and its Applications 421 (2015) C, pp. 533-540

In this paper, a new model of computer virus–antivirus propagation dynamics based on the topology nature of the … Internet is established. We analyze theoretically the complex dynamics of the model and it is found that, unlike the existing …

Network Analysis of Commuting Flows: A Comparative Static Approach to German Data

Patuelli, Roberto; Reggiani, Aura; Gorman, Sean; … - In: Networks and Spatial Economics 7 (2007) 4, pp. 315-331

The analysis of complex networks has recently received considerable attention. The work by Albert and Barabási presented a research challenge to network analysis, that is, growth of the network. The present paper offers a network analysis of the spatial commuting network in Germany. First, we...

Enhanced network reconstruction from irreducible local information

Mastrandrea, Rossana; Squartini, Tiziano; Fagiolo, Giorgio - 2013

Network topology plays a key role in many phenomena, from the spreading of diseases to that of financial crises. Whenever the whole structure of a network is unknown, one must resort to reconstruction methods that identify the least biased ensemble of networks consistent with the partial...

Migration and trade: A complex-network approach

Fagiolo, Giorgio; Mastrorillo, Marina - 2013

This paper explores the relationships between migration and trade using a complex-network approach. We show that: (i) both weighted and binary versions of the networks of international migration and trade are strongly correlated; (ii) such correlations can be mostly explained by country...

Endogenous space in the Net era

Arcangeli, E. Fabio; Padrin, Giorgio - 2004

Libre Software communities are among the most interesting and advanced socio-economic laboratories on the Net. In terms of directions of Regional Science research, this paper addresses a simple question: “Is the socio-economics of digital nets out of scope for Regional Science, or might the...

Propagation of economic shocks in input-output networks: A cross-country analysis

Alatriste Contreras, Martha G.; Fagiolo, Giorgio - 2014

This paper investigates how economic shocks propagate and amplify through the input-output network connecting industrial sectors in developed economies. We study alternative models of diffusion on networks and we calibrate them using input-output data on real-world inter-sectoral dependencies...

Leaders among the leaders in Economics: A network analysis of the Nobel Prize laureates

Molina, José Alberto; Iñiguez, David; Ruiz, Gonzalo; … - 2020

We analyse the production and networks of Nobel laureates in Economics, employing the Normalized Impact Factor (NIF) of their publications in the Journal of Citation Report (Economics), to identify the academic leaders among those laureates awarded between 1969 and 2016. Our results indicate...

Network topography and default contagion in China's financial system

Fittje, Jens; Wagner, Helmut - 2020

The topography of China's financial network is unique. Is it also uniquely robust to contagion? We explore this question using network theory. We find that networks that are more concentrated are less fragile when connectivity is low. However, they remain vulnerable to the occurrence of...
