Power-law distribution in the number of confirmed COVID-19 cases [PDF]
Chaos, 2020 COVID-19 is an emerging respiratory infectious disease caused by the coronavirus SARS-CoV-2. It was first reported on in early December 2019 in Wuhan, China and within three months spread as a pandemic around the whole globe.

Power-law distribution of degree-degree distance: A better representation of the scale-free property of complex networks. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance It is hard to decide if a real-world complex network is scale free, as it has never reached an agreement on how to confirm whether the network exhibits statistically favored power-law distributions. Here, we define a fundamental property—the

Explaining the power-law distribution of human mobility through transportation modality decomposition. [PDF]
Sci Rep, 2015 Human mobility has been empirically observed to exhibit Lévy flightcharacteristics and behaviour with power-law distributed jump size. The fundamentalmechanisms behind this behaviour has not yet been fully explained.

A power law distribution of metabolite abundance levels in mice regardless of the time and spatial scale of analysis [PDF]
Scientific Reports, 2018 Biomolecule abundance levels change with the environment and enable a living system to adapt to the new conditions. Although, the living system maintains at least some characteristics, e.g. homeostasis.

On the emergence of a power law in the distribution of COVID-19 cases [PDF]
Physica D: Nonlinear Phenomena, 2020 The first confirmed case of Coronavirus Disease 2019 (COVID-19) in the US was reported on January 21, 2020. By the end of March, 2020, there were more than 180,000 confirmed cases in the US, distributed across more than 2000 counties.

Power-law Distribution and Scale-invariant Structure from the First CHIME/FRB Fast Radio Burst Catalog [PDF]
Research in Astronomy and Astrophysics, 2022 We study the statistical property of fast radio bursts (FRBs) based on a selected sample of 190 one-off FRBs in the first CHIME/FRB catalog. Three power law models are used in the analysis, and we find the cumulative distribution functions of energy can ...

The Empirical Reality of IT Project Cost Overruns: Discovering A Power-Law Distribution [PDF]
Journal of Management Information Systems, 2022 If managers assume a normal or near-normal distribution of Information Technology (IT) project cost overruns, as is common, and cost overruns can be shown to follow a power-law distribution, managers may be unwittingly exposing their organizations to ...

Scale-free networks beyond power-law degree distribution [PDF]
Chaos, Solitons & Fractals, 2023 Complex networks across various fields are often considered to be scale free -- a statistical property usually solely characterized by a power-law distribution of the nodes' degree $k$. However, this characterization is incomplete. In real-world networks,

Evolution of the Complex Supply Chain Network Based on Deviation from the Power-Law Distribution
Applied Sciences, 2022 The power-law distribution is an important descriptive characteristic of scale-free complex supply chain networks (SCN). The power-law distribution and deviation phenomena of SCN nodes are explored in combination with complex network theory, so it is ...

The Modified Form of the Gutenberg-Richter Law in Solar Flare Complex Network : Approach of Genetic Algorithm on the Thresholded Power-Law Behavior [PDF]
Iranian Journal of Astronomy and Astrophysics, 2020 The hybrid model approach is adopted to construct the solar flare complex network. The modified form of Gutenberg-Richter law is obtained as the frequency-magnitude distribution of the empirical data.
