Taylor’s power law for the N-stars network evolution model

open access: yesModern Stochastics: Theory and Applications, 2019
Taylor’s power law states that the variance function decays as a power law. It is observed for population densities of species in ecology. For random networks another power law, that is, the power law degree distribution is widely studied.

Errors and uncertainties in microwave link rainfall estimation explored using drop size measurements and high-resolution radar data [PDF]

open access: yes, 2010
Microwave links can be used for the estimation of path-averaged rainfall by using either the path-integrated attenuation or the difference in attenuation of two signals with different frequencies and/or polarizations.

Mean-variance relationships of leaf bilateral asymmetry for 35 species of plants and their implications

open access: yesGlobal Ecology and Conservation, 2020
Leaf bilateral asymmetry, an important indicator of leaves that tend to be affected by the above-ground architectural structure of plants and their environments (especially light), has been poorly studied.

Variance in Landscape Connectivity Shifts Microbial Population Scaling

open access: yesFrontiers in Microbiology, 2022
Understanding mechanisms shaping distributions and interactions of soil microbes is essential for determining their impact on large scale ecosystem services, such as carbon sequestration, climate regulation, waste decomposition, and nutrient cycling.

Experimental study of Taylor's hypothesis in a turbulent soap film [PDF]

open access: yes, 1999
An experimental study of Taylor's hypothesis in a quasi-two-dimensional turbulent soap film is presented. A two probe laser Doppler velocimeter enables a non-intrusive simultaneous measurement of the velocity at spatially separated points.

Temporal Taylor's scaling of facial electromyography and electrodermal activity in the course of emotional stimulation [PDF]

open access: yes, 2016
High frequency psychophysiological data create a challenge for quantitative modeling based on Big Data tools since they reflect the complexity of processes taking place in human body and its responses to external events.

Dispersion pattern and fixed precision sequential sampling of Sitobion avenae (Fabricus) (Hemiptera: Aphididae) in wheat fields of Badjgah (Fars province) in Iran

open access: yesJournal of Entomological and Acarological Research, 2013
Understanding the dispersion pattern of a species is an important pre-requisite for developing an effective pest management program. In this study, four hundred wheat plants were surveyed for Sitobion avenae twice a week during 2010 and 2011 growing ...

Taylor Made Landscapes: Using Taylor's Law to Scale Between Metapopulations and Source-Sinks in Urban Garden Space

open access: yesFrontiers in Sustainable Food Systems, 2020
The structure of terrestrial landscapes is commonly viewed as a problem of statistical description defined by the number, size and distance between habitat patches.

Effect of weather variabilities on dispersion pattern of Nilaparvata lugens (Stål) (Homoptera: Delphacidae) in paddy field

open access: yesJournal of Agrometeorology, 2022
Field experiments were conducted to find out the impact of weather factors and crop phenological stages on the dispersion pattern of brown planthopper (BPH), Nilaparvata lugens (Stål) in paddy during kharif 2019 and 2020 at three paddy crop phenological

Fractional Gradient Elasticity from Spatial Dispersion Law [PDF]

open access: yes, 2014
Non-local elasticity models in continuum mechanics can be treated with two different approaches: the gradient elasticity models (weak non-locality) and the integral non-local models (strong non-locality).
