TL;DR: This paper proposes a generalization of the theory of small worlds based on two leading concepts, efficiency and cost, and valid also for weighted networks, and provides an adequate tool to quantitatively analyze the behaviour of complex networks in the real world.

TL;DR: The authors show that the absence of any clue of assortativity differentiates urban street networks from other non-geographic systems and that most of the considered networks have a broad degree distribution typical of scale-free networks and exhibit small-world properties as well.

TL;DR: This paper introduces multiple centrality assessment (MCA), a methodology for geographic network analysis, which is defined and implemented on four 1-square-mile urban street systems and shows that, in the MCA primal approach, some centrality indices nicely capture the ‘skeleton’ of the urban structure that impacts so much on spatial cognition and collective behaviours.

TL;DR: This model of the North American power grid using its actual topology and plausible assumptions about the load and overload of transmission substations indicates that the loss of a single substation can result in up to up to 25% loss of transmission efficiency by triggering an overload cascade in the network.

TL;DR: This paper presents a general framework to describe and study multiplex networks, whose links are either unweighted or weighted, and proposes a series of measures to characterize the multiplexicity of the systems in terms of basic node and link properties.
