Maximum and antimaximum principles for the $p$-Laplacian with weighted Steklov boundary conditions

Electronic Journal of Differential Equations, 2020
We study the maximum and antimaximum principles for the p-Laplacian operator under Steklov boundary conditions with an indefinite weight $$\displaylines{ -\Delta_p u + |u|^{p-2}u = 0 \quad \text{in }\Omega, \cr |\nabla u|^{p-2}\frac{\partial u ...

Bending Fatigue Evaluation and Failure Modes of Ultra‐Thin Silicon Chips on Flexible Substrates

FlexTech, EarlyView.
This study investigates the fatigue lifetime of 20‐μm‐thick chips under bending deformation. Three failure modes are identified: metal pad wearing, metal stress migration, and gold wire break. The underlying mechanisms are analyzed through micro‐scale characterization, and temperature effects on fatigue lifetime are explored.

Eigenvalues of the p-Laplacian in fractal strings with indefinite weights

Journal of Mathematical Analysis and Applications, 2005
The asymptotic behavior of the spectral counting function is studied for the boundary value problem \[ -(\psi_p(u'))'=\lambda r(x)\psi_p(u),\; x\in\Omega, \] with Dirichlet boundary conditions, where \(\Omega\) is a bounded open set in \({\mathbb R}\), \(p>1\), \(\lambda\) is a real spectral parameter, \(\psi_p(s)=| s| ^{p-2}s\), and the weight \(r ...

Reframing Clinical Supervision in Addiction Treatment: A Blended Developmental, Competency‐Based, and Trauma‐Informed Framework

Journal of Addictions &Offender Counseling, EarlyView.
ABSTRACT This article examines the current landscape of clinical supervision in addiction treatment and proposes a blended supervision framework integrating developmental, competency‐based, and trauma‐informed approaches. The article explores how this integrated model can enhance clinical competence, ethical practice, and counselor resilience while ...

Clinical Rationale of Dual‐Parameter Tumor Markers Reporting Without Reliance on Normal Reference Ranges

Journal of Clinical Laboratory Analysis, EarlyView.
We recommend the current practice of tumor marker reporting to upgrade to two‐figure format to include a specific growth rate in parentheses. This can be of great clinical importance, especially in the subnormal range. ABSTRACT Introduction This review offers clinicians a novel view of tumor markers (TM).

Dual biologic therapy in inflammatory bowel disease, a retrospective cohort study of vedolizumab and anti‐tumor necrosis factor alpha therapy in children

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Despite advances in pediatric inflammatory bowel disease (PIBD) with biologics, remission rates remain at 47%–60% with loss‐of‐response rates at 60%–68%. Evidence for efficacy of dual biologic therapy (DBT) with anti‐tumor necrosis factor alpha therapy (anti‐TNF‐α)‐ vedolizumab (VDZ) for children refractory to anti‐TNF‐α therapy is ...

Singular Sturm?Liouville problems with nonnegative and indefinite weights

Monatshefte f�r Mathematik, 1984
This article is concerned with the oscillatory properties of the eigenfunctions of a class of singular Sturm-Liouville problems \(- (py')'+qy=\lambda wy\) on (a,b), where the weight function w vanishes on a subinterval of positive measure, or where the weight function w changes sign on (a,b).
