A power law for cells [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
Darwin observed that multiple, lowly organized, rudimentary, or exaggerated structures show increased relative variability. However, the cellular basis for these laws has never been investigated. Some animals, such as the nematode Caenorhabditis elegans , are famous for having organs that ...

Simulation and Comparison of Non-Newtonian Fluid Models Using LBM in a Cavity [PDF]

open access: yesJournal of Heat and Mass Transfer Research, 2021
In this paper, simulation of non-Newtonian fluid flow in a two-dimension lid driven cavity is investigated. In this simulation Lattice Boltzmann method is used to solve computational fluid dynamics equations numerically.

POWER LAWS ARE LOGARITHMIC BOLTZMANN LAWS [PDF]

open access: yesInternational Journal of Modern Physics C, 1996
Multiplicative random processes in (not necessarily equilibrium or steady state) stochastic systems with many degrees of freedom lead to Boltzmann distributions when the dynamics is expressed in terms of the logarithm of the elementary variables. In terms of the original variables this gives a power-law distribution.

Snooker Statistics and Zipf’s Law

open access: yesStats, 2022
Zipf’s law is well known in linguistics: the frequency of a word is inversely proportional to its rank. This is a special case of a more general power law, a common phenomenon in many kinds of real-world statistical data.

The powerful law of the power law and other myths in network biology [PDF]

open access: yesMolecular BioSystems, 2009
Abstract For almost 10 years, topological analysis of different large-scale biological networks (metabolic reactions, protein interactions, transcriptional regulation) has been highlighting some recurrent properties: power law distribution of degree, scale-freeness, small world, which have been proposed to confer functional advantages

The Gender Productivity Gap in Croatian Science: Women Are Catching up with Males and Becoming Even Better

open access: yesEntropy, 2020
How much different genders contribute to citations and whether we see different gender patterns between STEM and non-STEM researchers are questions that have long been studied in academia.

Description of the Distribution Law and Non-Linear Dynamics of Growth of Comments Number in News and Blogs Based on the Fokker-Planck Equation

open access: yesMathematics, 2022
The article considers stationary and dynamic distributions of news by the number of comments. The processing of the observed data showed that static distribution of news by the number of comments relating to that news obeys a power law, and the dynamic ...

Scaling Invariance of Sports Sex Gap

open access: yesFrontiers in Physiology, 2020
The controversy over the evolution of sex gap in sports stems from the reported that women’s performance will 1 day overtake men’s in the journal Nature.
