Zipf's law in income distribution of companies
TL;DR: In this article, a clear power law distribution consistent with the Zipf's law can be confirmed for Japanese companies over more than three decades in income scale, and it is confirmed that such power laws hold in most of job categories with slightly modified exponents.

1/f NOISE IN A TRAFFIC MODEL
Misako Takayasu,Hideki Takayasu +1 more
TL;DR: One-dimensional traffic flow is simulated by a cellular-automaton-type discrete model, which shows a phase transition between a jam phase and a non-jam phase and by adding random perturbations finds a 1/f power spectrum in the jam phase, whereas a white noise is observed in the non- jam phase.
Journal ArticleDOI
Stable infinite variance fluctuations in randomly amplified langevin systems
Journal ArticleDOI
Correlation networks among currencies
TL;DR: In this paper, a hierarchical taxonomy of currencies constructing minimal-spanning trees is derived by analyzing the foreign exchange market data of various currencies, and the key currencies in each cluster are found.
Journal ArticleDOI
Extinction, survival, and dynamical phase transition of branching annihilating random walk.
TL;DR: Analysis of statistical properties of random walkers which disappear when they meet and make offsprings by a controllable rate and Universality classes are found to depend on the number of offsprins in space dimension less than 3.
