Eigenvalues homogenization for the fractional p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2016
In this work we study the homogenization for eigenvalues of the fractional p-Laplace operator in a bounded domain both with Dirichlet and Neumann conditions. We obtain the convergence of eigenvalues and the explicit order of the convergence rates when

Existence of Weak Solutions for a Degenerate Goursat‐Type Linear Problem

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT For a generalization of the Gellerstedt operator with mixed‐type Dirichlet boundary conditions to a suitable Tricomi domain, we prove the existence and uniqueness of weak solutions of the linear problem and for a generalization of this problem.

Solving p-Laplacian equations on complete manifolds

open access: yesElectronic Journal of Differential Equations, 2006
Using a reduced version of the sub and super-solutions method, we prove that the equation $Delta _{p}u+ku^{p-1}-Ku^{p^{ast }-1}=0$ has a positive solution on a complete Riemannian manifold for appropriate functions $k,K:Mo mathbb{R}$.

Optimization in problems involving the p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2010
We minimize the energy integral $int_Omega | abla u|^p,dx$, where $g$ is a bounded positive function that varies in a class of rearrangements, $p>1$, and $u$ is a solution of $$displaylines{ -Delta_p u=g quadhbox{in } Omegacr u=0quad hbox{on ...

Counting glomeruli in human kidney specimens using ex vivo MRI without contrast agents

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose The total number of glomeruli is an important indicator of kidney function and susceptibility to disease. Glomeruli, however, are difficult to image using MRI without contrast enhancement. For this reason, previous studies have used cationic ferritin as a contrast agent to detect glomeruli in ex vivo and in vivo perfused kidneys.

Image‐Based Flaw Identification Using Convolutional Neural Network

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Flaw detection in structures is crucial for ensuring structural integrity and safety across various engineering applications. Traditional nondestructive evaluation (NDE) techniques often face challenges in accurately identifying and characterizing flaws, particularly when dealing with complex geometries and strain fields.

Advanced Modeling of Thermo‐Mechanical Behavior in Tetrachiral Core Sandwich Nanoplates Using Non‐Local Higher‐Order Theory

open access: yesNatural Sciences, EarlyView.
The study presented investigates the thermo‐mechanical behavior of a sandwich structure with a tetrachiral‐shaped auxetic core. The geometric configuration, unit cell architecture, and the influence of the material length scale on the effective stiffness under temperature variation are illustrated.

Fundamental solutions to the p-Laplace equation in a class of Grushin vector fields

open access: yesElectronic Journal of Differential Equations, 2011
We find the fundamental solution to the p-Laplace equation in a class of Grushin-type spaces. The singularity occurs at the sub-Riemannian points, which naturally corresponds to finding the fundamental solution of a generalized Grushin operator in ...
