A Prediction Equation to Estimate Vascular Endothelial Function in Different Body Mass Index Populations

open access: yesFrontiers in Cardiovascular Medicine, 2022
ObjectiveVascular endothelial dysfunction is considered an early predictor of endothelial injury and the initiating factor of atherosclerosis (AS). Brachial artery flow-mediated dilation (FMD) can detect endothelial injury early and provide important ...

A SINISTER VIEW OF DILATION EQUATIONS [PDF]

open access: yesInternational Journal of Wavelets, Multiresolution and Information Processing, 2005
We present a technique for studying refinable functions which are compactly supported. Refinable functions satisfy dilation equations and this technique focuses on the implications of the dilation equation at the edges of the support of the refinable function.

Simultaneous Extraction of Planetary Boundary-Layer Height and Aerosol Optical Properties from Coherent Doppler Wind Lidar

open access: yesSensors, 2022
Planetary boundary-layer height is an important physical quantity for weather forecasting models and atmosphere environment assessment. A method of simultaneously extracting the surface-layer height (SLH), mixed-layer height (MLH), and aerosol optical ...

Dilaton Mass Formulas in a Hairy Binary Black Hole Model

open access: yes, 2020
In this note an analytic integration is obtained for the differential equation governing the scalar-field-dependent mass in a hairy binary black hole model, in the context of the Einstein--Maxwell--dilation theory, which gives a closed-form formula-level

Numerical solution of partial differential equations using Daubechies Filter with accuracy order six [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
his article considers the representation of differentiation operators using Daubechies wavelets to solve PDEs numerically. Derivative approximation using this compactly supported wavelets convert the action into a matrix multiplication.

Scalar Field Models of Barrow Holographic Dark Energy in f(R,T) Gravity

open access: yesUniverse, 2022
This research study investigates Barrow holographic dark energy with an energy density of ρΛ=CH2−Δ by considering the Hubble horizon as the IR cut-off in the f(R,T) gravity framework. We employ Barrow holographic dark energy to obtain the equation of the

Differential transcendence criteria for second-order linear difference equations and elliptic hypergeometric functions [PDF]

open access: yes, 2019
We develop general criteria that ensure that any non-zero solution of a given second-order difference equation is differentially transcendental, which apply uniformly in particular cases of interest, such as shift difference equations, q-dilation ...

Strength of shear bands in fluid-saturated rocks: a nonlinear effect of competition between dilation and fluid flow

open access: yesScientific Reports, 2018
This study shows the significant and nonlinear effect of the competition between dilation and fluid flow on the shear strength of constrained shear bands in fluid-saturated rocks. This effect is conditioned by the contribution of the pore pressure to the
