TL;DR: A new algorithm based on a network measure, local betweenness centrality (LBC), for search in complex networks that are heterogeneous in node degree and edge weights and performs the best in scale-free weighted networks is proposed.
Abstract: a new algorithm based on a network measure, local betweenness centrality (LBC), for search in complex networks that are heterogeneous in node degree and edge weights. LBC search utilizes both the heterogeneities and performs the best in scale-free weighted networks. We further argue that the amount of information used by LBC search could be optimal.

TL;DR: In this paper, the role of network forms of organisation in the development of innovative processes is analyzed. But the authors consider several definitions of network form of organisation, including those typical of the sphere of innovations.
Abstract: This article analyses the role of network forms of organisation in the development of innovative processes. The authors consider several definitions of network forms of organisation, including those typical of the sphere of innovations. The article offers an analysis of the explanation of the network phenomenon in the social exchange theory, M. Castells"s network theory, resource dependence theory, organisational sociology theory, new institutionalism, evolutionary economics, and French economic institutionalism.

TL;DR: Turbulent mixing and diffusion are investigated in the Lagrangian framework using tools proper to network theory to characterize the tendency of tracers to group in coherent structures, or clusters, despite being driven further and further away by the diffusive action of turbulence.
Abstract: Turbulent mixing and diffusion are investigated in the Lagrangian framework using tools proper to network theory. Starting from a database of trajectories of non-inertial particles obtained through direct numerical simulation of a channel flow, two innovative analysis tools are developed and discussed. The first tool aims to characterize the tendency of tracers to group in coherent structures, or clusters, despite being driven further and further away by the diffusive action of turbulence. The second tool deals with the diffusion and transport of particles in the only inhomogeneous direction of the channel flow, which is the wall normal one. In both tools particles (or sets of them) are represented as graph nodes, while different definition of links are given. Network theory offers a powerful framework to analyse complex dynamical behaviour in large datasets.

TL;DR: In this paper, an approach based on network theory applied to evaluate the relationships between the economic sectors belonging to the copyright network in Italy is presented. But the results show that it is possible to introduce a new investigative model for copyright-based industry networks.
Abstract: Research into the economic contribution of copyright networks has revealed the impact that industrial groups have on financial performance, the added value created and the increased number of employees generated by this industry, whilst excluding any evaluation of the relationships that exist between the industries and sectors that operate in a copyright network. Drawing on the Economic Theory of Copyright and on Network Theory, the aim of this research is to address the question of how to determine the economic contribution that copyright industries have on individual nations, by means of an approach based on Network Theory applied to evaluate the relationships between the economic sectors belonging to the copyright network in Italy. In this research, a mixed method design was used to gather both quantitative and qualitative data in two phases. The results show that it is possible to introduce a new investigative model for copyright-based industry networks.
