TL;DR: It is found that the worldwide air transportation network is a scale-free small-world network, and it is demonstrated that the most connected cities are not necessarily the most central, resulting in anomalous values of the centrality.

TL;DR: A model in which particles interact with short-ranged attractive and long-ranged repulsive interactions is studied, in an attempt to model the equilibrium cluster phase recently discovered in sterically stabilized colloidal systems in the presence of depletion interactions.

TL;DR: A general model for the growth of scale-free networks under filtering information conditions-that is, when the nodes can process information about only a subset of the existing nodes in the network-is formulated.

TL;DR: This work simulates the new water model proposed by Mahoney and Jorgensen in a wide range of deeply supercooled states and finds the existence of a nonmonotonic "nose-shaped" temperature of maximum density line and a nonreentrant spinodal.

TL;DR: Calculated ground-state energies and geometries for clusters of different sizes, where individual particles interact simultaneously via a short-ranged attractive potential, modeled with a generalization of the Lennard-Jones potential, and a long-ranged repulsive Yukawa potential show that for specific choices of the parameters of the repulsive potential, the ground- state energy per particle has a minimum at a finite cluster size.
