A power law distribution of metabolite abundance levels in mice regardless of the time and spatial scale of analysis [PDF]

open access: yesScientific 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.

The Modified Form of the Gutenberg-Richter Law ‎in ‎Solar ‎Flare ‎Complex ‎Network‎ : ‎Approach of Genetic Algorithm on the Thresholded Power-Law Behavior [PDF]

open access: yesIranian 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.

Evolution of the Complex Supply Chain Network Based on Deviation from the Power-Law Distribution

open access: yesApplied 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 ...

Firm-Size Distribution in Poland: Is Power Law Applicable?

open access: yesGospodarka Narodowa. The Polish Journal of Economics, 2021
This article focuses on the existence of power laws in the firm-size distribution in Poland. Specifically, we empirically test whether the size distribution of companies in Poland has the characteristics of Zipf ’s law, a special case of power law ...

Research on Weight Initialization Method in Deep Learning [PDF]

open access: yesJisuanji gongcheng, 2022
The essence of deep neural network training is the constant adjustment of the initial weight, and the entire training process is time consuming and requires a large amount of data.Most pretraining networks are essentially trained weight data.If the ...

Statistical analyses support power law distributions found in neuronal avalanches. [PDF]

open access: yesPLoS ONE, 2011
The size distribution of neuronal avalanches in cortical networks has been reported to follow a power law distribution with exponent close to -1.5, which is a reflection of long-range spatial correlations in spontaneous neuronal activity.

Power law statistics of force and acoustic emission from a slowly penetrated granular bed [PDF]

open access: yesNonlinear Processes in Geophysics, 2014
Penetration-resistant force and acoustic emission (AE) from a plunged granular bed are experimentally investigated through their power law distribution forms. An AE sensor is buried in a glass bead bed.
