Volume conduction and EEG measurements within the brain: A quantitative approach to the influence of electrical spread on the linear relationship of activity measured at different locations [PDF]

open access: yes, 1977
When recording referentially brain field potentials with several electrodes at relatively small tip separations, a linear relationship between the simultaneously recorded signals may arise solely as a result of volume conduction (electrical spread).

The Linear Relationship Model with LASSO for Studying Stock Networks

open access: yesEntropy, 2022
The correlation-based network is a powerful tool to reveal the influential mechanisms and relations in stock markets. However, current methods for developing network models are dominantly based on the pairwise relationship of positive correlations.

Why Do the Maximum Intensities in Modeled Tropical Cyclones Vary Under the Same Environmental Conditions?

open access: yesGeophysical Research Letters, 2020
In this study w e explored why the different initial tropical cyclone structures can result in different steady‐state maximum intensities in model simulations with the same environmental conditions. We discovered a linear relationsh ip between the radius

Establishment and clinical application of a droplet digital PCR method for the detection of Edwardsiella tarda

open access: yesFrontiers in Veterinary Science
Edwardsiella tarda (E. tarda) can infect humans and a variety of animals, including fish, amphibians, reptiles, birds, and mammals. However, a more highly sensitive, specific, and repeatable test for its detection is lacking.

Estimating a bivariate linear relationship

open access: yes, 2012
Solutions of the bivariate, linear errors-in-variables estimation problem with unspecified errors are expected to be invariant under interchange and scaling of the coordinates.

A method for estimating the extent of denitrification of Arctic polar vortex air from tracer-tracer scatter plots [PDF]

open access: yes, 2002
A method for estimating the extent of denitrification of Arctic polar vortex air is proposed. Previous estimates of denitrification using tracer-tracer scatter plots have not allowed for mixing-induced changes in tracer-tracer relationships in a ...
