Blow-up for p-Laplacian parabolic equations
Electronic Journal of Differential Equations, 2003 In this article we give a complete picture of the blow-up criteria for weak solutions of the Dirichlet problem $$ u_t= abla(| abla u|^{p-2} abla u)+lambda |u|^{q-2}u,quad hbox{in } Omega_T, $$ where $p>1$.

Head &Neck, EarlyView.ABSTRACT Background Endoscopy is essential in upper aerodigestive tract (UADT) examination, particularly in the early detection of laryngopharyngeal lesions. However, UADT endoscopy remains operator‐dependent and lacks standardized quality metrics. Recent advancements in artificial intelligence (AI) have generated interest in applications within UADT ...

Steklov problems involving the p(x)-Laplacian
Electronic Journal of Differential Equations, 2014 Under suitable assumptions on the potential of the nonlinearity, we study the existence and multiplicity of solutions for a Steklov problem involving the p(x)-Laplacian. Our approach is based on variational methods.

(p,q)-Laplacian elliptic systems at resonance
Electronic Journal of Differential Equations, 2016 We show the existence of weak solutions for a class of (p,q)-Laplacian elliptic systems at resonance, under certain Landesman-Lazer-type conditions by using critical point theorem.

Movement Disorders, EarlyView.Abstract Objective To compare iron deposition in the substantia nigra (SN) as measured with quantitative susceptibility mapping (QSM) on antemortem magnetic resonance imaging (MRI) between individuals with and without Lewy‐related pathology at autopsy. Methods We performed a retrospective cohort study including 54 participants who underwent autopsy and

Movement Disorders, EarlyView.Abstract Background Impaired glymphatic clearance may contribute to pathological accumulations in Parkinson's (PD), but how it interacts with other processes causing dementia remains unclear. Diffusion tensor image analysis along the perivascular space (DTI‐ALPS) has been proposed as an indirect proxy for glymphatic clearance. Objectives To clarify DTI‐
