Degree distributions in networks: Beyond the power law [PDF]

open access: yesStatistica Neerlandica
AbstractThe power law is useful in describing count phenomena such as network degrees and word frequencies. With a single parameter, it captures the main feature that the frequencies are linear on the log‐log scale. Nevertheless, there have been criticisms of the power law, for example, that a threshold needs to be preselected without its uncertainty ...

Scale-Free Features in Collective Robot Foraging

open access: yesApplied Sciences, 2019
In many complex systems observed in nature, properties such as scalability, adaptivity, or rapid information exchange are often accompanied by the presence of features that are scale-free, i.e., that have no characteristic scale.

Molecular clouds have power-law probability distribution functions [PDF]

open access: yes, 2015
In this Letter we investigate the shape of the probability distribution of column densities (PDF) in molecular clouds. Through the use of low-noise, extinction-calibrated \textit{Herschel}/\textit{Planck} emission data for eight molecular clouds, we ...
