An Adsorption Equilibria Model for Steady State Analysis

open access: yesInternational Journal of Technology, 2016
The investigation of adsorption isotherms is a prime factor in the ongoing development of adsorption cycles for a spectrum of advanced, thermally-driven engineering applications, including refrigeration, natural gas storage, and desalination processes.

Size structure of earthworms populations and the theory of neutrality

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2007
The paper points that neutrality theory allows to describe a distribution of earthworms’ body weight classes in the population. The statistical parameters can be interpreted in terms of the population ecology. The dynamics of parameters distribution over

Spectral fluctuations effects on conductance peak height statistics in quantum dots

open access: yes, 2002
Within random matrix theory for quantum dots, both the dot's one-particle eigenlevels and the dot-lead couplings are statistically distributed. While the effect of the latter on the conductance is obvious and has been taken into account in the literature,

Vortex distribution in a confining potential [PDF]

open access: yes, 2013
We study a model of interacting vortices in a type II superconductor. In the weak coupling limit, we constructed a mean-field theory which allows us to accurately calculate the vortex density distribution inside a confining potential.

Extended Matrix Variate Hypergeometric Functions and Matrix Variate Distributions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
Hypergeometric functions of matrix arguments occur frequently in multivariate statistical analysis. In this paper, we define and study extended forms of Gauss and confluent hypergeometric functions of matrix arguments and show that they occur naturally ...

A New Approach to Bivariate Transmutation: Construction of Continuous Bivariate Distribution Under Negative Dependency

open access: yesCumhuriyet Science Journal, 2020
In this study, a new approach to transmutation theory is developed by using negative dependency basement. Once choosing a distribution that has negative dependency with the same marginal, a new bivariate distribution is derived.

Zero-bias anomaly and role of electronic correlations in a disordered metal film

open access: yesNew Journal of Physics, 2020
Localization and electron correlation play significant roles in understanding the electronic states of low-dimensional systems. We carried out the tunneling spectroscopy measurements on a crystalline nano-sized island and a disordered two-dimensional ...

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
