Centered Polygonal Lacunary Graphs: A Graph Theoretic Approach to p-Sequences of Centered Polygonal Lacunary Functions

open access: yesMathematics, 2019
This work is on the nature and properties of graphs which arise in the study of centered polygonal lacunary functions. Such graphs carry both graph-theoretic properties and properties related to the so-called p-sequences found in the study of centered ...

Enhanced removal of scaling cations from oilfield produced water by carrier mineral floatation

open access: yesWater Science and Technology, 2021
This work reports a novel carrier flotation protocol for removing scaling cations from an oilfield produced water source which significantly reduces the collector consumption by employing natural minerals such as quartz, montmorillonite and talcum as the

Quantum electrodynamics with anisotropic scaling: Heisenberg-Euler action and Schwinger pair production in the bilayer graphene [PDF]

open access: yes, 2012
We discuss quantum electrodynamics emerging in the vacua with anisotropic scaling. Systems with anisotropic scaling were suggested by Horava in relation to the quantum theory of gravity.

Precipitation to remove calcium ions from stabilized human urine as a pre-treatment for reverse osmosis

open access: yesWater Science and Technology, 2021
Concentration of Ca(OH)2 stabilized urine by reverse osmosis (RO) has the potential to cause CaCO3 scaling on the membranes. The aim of this research was to determine whether the addition of carbonate salts could be used to precipitate CaCO3 prior to RO ...

A scaling normalization method for differential expression analysis of RNA-seq data

open access: yesGenome Biology, 2010
The fine detail provided by sequencing-based transcriptome surveys suggests that RNA-seq is likely to become the platform of choice for interrogating steady state RNA.

Fear and Anxiety among patients treated by scaling in Periodontally healthy subjects

open access: yesAsian Journal of Medical Sciences, 2017
Background: Anxiety and fear experience represent significant problems in dental practice and are the factors that discourage the demand for treatment. They affect the use of health care services, treatment decision-making, and responses to periodontal ...

Wavelet-based systematic risk estimation: application on GCC stock markets: the Saudi Arabia case

open access: yesQuantitative Finance and Economics, 2020
Systematic risk estimation is widely applied by investors and managers in order to predict risks in the market. One of the most applied measures of risk is the so-called Capital Asset Pricing Model, shortly CAPM.

Introducing Variations of Predictors as Optional Predictors Offers the Potential to Improve the Downscaling Performance of Geographically Weighted Regression Model

open access: yesIEEE Access, 2023
Are the variations of the fine predictors at the spatial scale of the target variable to be downscaled helpful for spatial downscaling? However, few studies have explored this topic. In this study, one of the most frequently downscaled satellite products

Asymptotic Scaling, Casimir Scaling, and Center Vortices

open access: yes, 1998
We report on two recent developments in the center vortex theory of confinement: (i) the asymptotic scaling of the vortex density, as measured in Monte Carlo simulations; and (ii) an explanation of Casimir scaling and the adjoint string tension, in terms

Scaling the Variance of a Latent Variable While Assuring Constancy of the Model

open access: yesFrontiers in Psychology, 2019
This paper investigates how the major outcome of a confirmatory factor investigation is preserved when scaling the variance of a latent variable by the various scaling methods. A constancy framework, based upon the underlying factor analysis formula that
