Numerical Solution of the Absolute Value Equations Using Two Matrix Splitting Fixed Point Iteration Methods

open access: yesJournal of Function Spaces, 2022
The absolute value equations (AVEs) are significant nonlinear and non-differentiable problems that arise in the optimization community. In this article, we provide two new iteration methods for determining AVEs.

A new two-step iterative method for solving absolute value equations

open access: yesJournal of Inequalities and Applications, 2019
We describe a new two-step iterative method for solving the absolute value equations Ax−|x|=b $Ax-|x|=b$, which is an NP-hard problem. This method is globally convergent under suitable assumptions.

Dynamic growth estimates of maximum vorticity for 3D incompressible Euler equations and the SQG model [PDF]

open access: yes, 2012
By performing estimates on the integral of the absolute value of vorticity along a local vortex line segment, we establish a relatively sharp dynamic growth estimate of maximum vorticity under some assumptions on the local geometric regularity of the ...

Modified HS conjugate gradient method for solving generalized absolute value equations

open access: yesJournal of Inequalities and Applications, 2019
We investigate a kind of generalized equations involving absolute values of variables as |A|x−|B||x|=b $|A|x-|B||x|=b$, where A∈Rn×n $A \in R^{n\times n}$ is a symmetric matrix, B∈Rn×n $B \in R^{n\times n}$ is a diagonal matrix, and b∈Rn $b\in R^{n}$.

Dynamics of a thin liquid film with surface rigidity and spontaneous curvature

open access: yes, 2011
The effect of rigid surfaces on the dynamics of thin liquid films which are amenable to the lubrication approximation is considered. It is shown that the Helfrich energy of the layer gives rise to additional terms in the time-evolution equations of the ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.
