Oscillation of second-order Emden-Fowler neutral delay differential equations

open access: yesElectronic Journal of Differential Equations, 2018
In this article, we establish new oscillation criteria for the second-order Emden-Fowler neutral delay differential equation $$ \Big(r(t)|z'(t)|^{\alpha-1}z'(t)\Big)'+q(t)|x(\sigma(t))|^{\beta-1} x\big(\sigma(t)\big)=0, $$ where $z(t)=x(t)+p(t)x ...

Clinical, histological, and serological predictors of renal function loss in lupus nephritis.

open access: yesArthritis Care &Research, Accepted Article.
Objective Kidney survival is the ultimate goal in lupus nephritis (LN) management, but long‐term predictors remain inadequately studied, requiring long‐term follow‐up. This study aimed to identify baseline and early longitudinal predictors of kidney survival in the Accelerating Medicines Partnership LN longitudinal cohort.

Generalized Picone and Riccati inequalities for half-linear differential operators with arbitrary elliptic matrices

open access: yesElectronic Journal of Differential Equations, 2010
In the article, we extend the well-known Picone identity for half-linear partial differential equations to equations with anisotropic p-Laplacian.

Oscillation criteria for half-linear second order differential equations

open access: yesHiroshima Mathematical Journal, 1995
Some oscillation criteria are given for the second order nonlinear differential equation \[ [\Phi(u'(t))]'+ c(t)\Phi(u(t))=0, \] where \(c(t)\) is a continuous function on \([0,\infty)\) and \(\Phi:\mathbb{R}\to\mathbb{R}\) is defined by \(\Phi(x)=|x|^{p-2}x\) with \(p>1\) a fixed real number.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Oscillation criteria for half-linear second order differential equations

open access: yesHiroshima Mathematical Journal, 1998
This article concerns oscillatory properties for quasilinear differential equations of type \[ -(| y'|^{p-2} y')'= f(x)| y|^{p-2}y,\quad x\in\mathbb{R}_+,\tag{1} \] with \(p>1\) and \(f\in C(\mathbb{R}_+,\mathbb{R})\). The main theorem states that (1) is oscillatory at \(\infty\) if \[ \lim_{x\to\infty} \log x\int^\infty_x [f(t)- (qt)^{-p}] t^{p-1}dt ...

Electrochemical Evaluation of Compressed Selective Laser Melted AlSi7Mg and AlSi10Mg Alloys in Chloride Environment

open access: yesAdvanced Engineering Materials, EarlyView.
The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
