Multivariate Mixed EWMA-CUSUM Control Chart for Monitoring the Process Variance-Covariance Matrix
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
The dispersion control charts monitor the variability of a process that may increase or decrease. An increase in dispersion parameter implies deterioration in the process for an assignable cause, while a decrease in ...
Effects of Fine-Grained Particles' Migration and Clogging in Porous Media on Gas Production from Hydrate-Bearing Sediments
(
Hindawi Limited
, 2019 , Article)
The migration of fine particles in porous media has been studied for different applications, including gas production from hydrate-bearing sediments. The clogging behavior of fine particles is affected by fine particle-pore ...

Encoding the β-Arrestin Trafficking Fate of Ghrelin Receptor GHSR1a: C-Tail-Independent Molecular Determinants in GPCRs
(
American Chemical Society
, 2019 , Article)
G-protein-coupled receptors (GPCRs) can bias signaling through distinct biochemical pathways that originate from G-protein/receptor and β-arrestin/receptor complexes. Receptor conformations supporting β-arrestin engagement ...
Co2+ substituted for Bi3+ in BiVO4 and its enhanced photocatalytic activity under visible LED light irradiation
(
Royal Society of Chemistry
, 2019 , Article)
We investigated the fabrication of Co-doped BiVO4 (Bi1-xCoxVO4+δ, 0.05 < x < 0.5) by the substitution of Co ions for Bi sites in BiVO4. The X-ray diffraction (XRD), Raman, and X-ray photoelectron spectroscopy (XPS) results ...
SAR and molecular mechanism studies of monoamine oxidase inhibition by selected chalcone analogs
(
Taylor and Francis Ltd.
, 2019 , Article)
The present study describes the synthesis of a series of 22 chalcone analogs. These compounds were evaluated as potential human MAO-A and MAO-B inhibitors. The compounds showed varied selectivity against the two isoforms. ...
Drug-free holidays: Compliance, tolerability, and acceptability of a 3-day atovaquone/proguanil schedule for pretravel malaria chemoprophylaxis in australian travelers
(
Oxford University Press
, 2019 , Article)
Background
Poor compliance with chemoprophylaxis is a major contributing factor to the risk of malaria in travelers. Pre-travel chemoprophylaxis may improve compliance by enabling “drug-free holidays.” The standard treatment ...
Postprandial insulin and triglyceride concentrations are suppressed in response to breaking up prolonged sitting in Qatari females
(
Frontiers Media S.A.
, 2019 , Article)
Background: Cultural, environmental and logistical factors challenge the Qatari population, particularly females, to engage in physical activity, and there is a high prevalence of diabetes in this population. Sedentary ...
Some Majorization Integral Inequalities for Functions Defined on Rectangles Via Strong Convexity
(
Ilirias Research Institute
, 2019 , Article)
In this paper, we have extended some integral majorization types and generalized Favard’s inequalities from functions defined on intervals to functions defined on rectangles via strong convexity and apply the results to ...
