Zipf's law unzipped
Why does Zipf's law give a good description of data from seemingly completely unrelated phenomena? Here it is argued that the reason is that they can all be described as outcomes of a ubiquitous raExpand

Networks and cities: an information perspective.
TLDR
We replot the road map of cities in terms of the information needed to locate specific addresses and create information city networks with roads mapped to nodes and intersections to links between nodes. Expand

Hierarchy measures in complex networks.
TLDR
Using each node's degree as a proxy for its importance, the topological hierarchy of a complex network is introduced and quantified. Expand

The meta book and size-dependent properties of written language
TLDR
Evidence is given for a systematic decrease in the power-law index γ of the wfd, from γ ≈ 2 for short novels to the infinite book size limit with γ = 1. Expand

Dynamic instabilities induced by asymmetric influence: prisoners' dilemma game in small-world networks.
A two-dimensional small-world-type network, subject to spatial prisoners' dilemma dynamics and containing an influential node defined as a special node, with a finite density of directed random linksExpand

Searchability of networks.
We investigate the searchability of complex systems in terms of their interconnectedness. Associating searchability with the number and size of branch points along the paths between the nodes, weExpand

Size dependent word frequencies and translational invariance of books
TLDR
It is shown that a real novel shares many characteristic features with a null model in which the words are randomly distributed throughout the text. Expand

Flow improvement caused by agents who ignore traffic rules.
TLDR
A system of agents moving along a road in both directions is studied numerically within a cellular-automata formulation. Expand

Double stochastic resonance peaks in systems with dynamic phase transitions
To probe the connection between the dynamic phase transition and stochastic resonance, we study the mean-field kinetic Ising model and the two-dimensional Josephson-junction array in the presence ofExpand

Non-Kosterlitz-Thouless transitions for the q-state clock models.
The q -state clock model with the cosine potential has a single phase transition for q≤4 and two transitions for q≥5 . It is shown by Monte Carlo simulations that the helicity modulus for theExpand
