A framework to approach problems of forensic anthropology using complex networks

Caridi, Inés; Dorso, Claudio O.; Gallo, Pablo; … - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 9, pp. 1662-1676

We have developed a method to analyze and interpret emerging structures in a set of data which lacks some information. It has been conceived to be applied to the problem of getting information about people who disappeared in the Argentine state of Tucumán from 1974 to 1981. Even if the military...

Community structure of complex software systems: Analysis and applications

Šubelj, Lovro; Bajec, Marko - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 16, pp. 2968-2975

Due to notable discoveries in the fast evolving field of complex networks, recent research in software engineering has … complex networks, i.e. community structure. We adopt class dependency networks, where nodes represent software classes and …, characterized by similar properties as observed in other complex networks. However, although intuitive and anticipated by different …

Synchronization in scale free networks with degree correlation

La Rocca, C.E.; Braunstein, L.A.; Macri, P.A. - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 15, pp. 2840-2844

In this paper we study a model of synchronization process on scale free networks with degree–degree correlations. This model was already studied on this kind of networks without correlations by Pastore y Piontti et al. [A.L. Pastore y Piontti, P.A. Macri, L.A. Braunstein, Phys. Rev. E 76...

Effects of the underlying topology on perturbation spreading in the Axelrod model for cultural dissemination

Kim, Yup; Cho, Minsoo; Yook, Soon-Hyung - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 21, pp. 3989-3995

We study the effects of the underlying topologies on a single feature perturbation imposed to the Axelrod model of consensus formation. From the numerical simulations we show that there are successive updates which are similar to avalanches in many self-organized criticality systems when a...

The influence of tie strength on evolutionary games on networks: An empirical investigation

Buesser, Pierre; Peña, Jorge; Pestelacci, Enea; … - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 23, pp. 4502-4513

Extending previous work on unweighted networks, we present here a systematic numerical investigation of standard evolutionary games on weighted networks. In the absence of any reliable model for generating weighted social networks, we attribute weights to links in a few ways supported by...

Generating random graphs with tunable clustering coefficients

Heath, Lenwood S.; Parikh, Nidhi - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 23, pp. 4577-4587

Most real-world networks exhibit a high clustering coefficient—the probability that two neighbors of a node are also neighbors of each other. We propose two algorithms, Conf and Throw, that take triangle and single edge degree sequences as input and generate a random graph with a target...

Phase diagram of epidemic spreading — unimodal vs. bimodal probability distributions

Lančić, Alen; Antulov-Fantulin, Nino; Šikić, Mile; … - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 1, pp. 65-76

Disease spreading on complex networks is studied in SIR model. Simulations on empirical complex networks reveal two … complex networks are introduced. A theoretical model of disease spreading on m-ary tree is investigated both analytically and … observed in empirical complex networks. The role of tree-like structure of complex networks in disease spreading is discussed. …

On the efficiency of data representation on the modeling and characterization of complex networks

Ruggiero, Carlos Antônio; Bruno, Odemir Martinez; … - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 11, pp. 2172-2180

Specific choices about how to represent complex networks can have a substantial impact on the execution time required … representing complex networks statically by adjacency matrices or dynamically by adjacency lists. Three theoretical models of … complex networks are considered: two types of Erdős–Rényi as well as the Barabási–Albert model. We investigated the effect of …

Modeling the effects of social impact on epidemic spreading in complex networks

Ni, Shunjiang; Weng, Wenguo; Zhang, Hui - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 23, pp. 4528-4534

We investigate by mean-field analysis and extensive simulations the effects of social impact on epidemic spreading in various typical networks with two types of nodes: active nodes and passive nodes, of which the behavior patterns are modeled according to the social impact theory. In this study,...
