Three positive solutions for p-Laplacian functional dynamic equations on time scales
Electronic Journal of Differential Equations, 2007 In this paper, we establish the existence of three positive solutions to the following p-Laplacian functional dynamic equation on time scales, $$displaylines{ [ Phi _p(u^{Delta }(t))] ^{ abla}+a(t)f(u(t),u(mu (t)))=0,quad tin (0,T)_{mathbf{T}}, cr ...

Positive solutions to sublinear elliptic problems
Colloquium Mathematicum, 2019 Let $L$ be a second order elliptic operator $L$ with smooth coefficients defined on a domain $Ω$ in $\mathbb{R}^d $, $d\geq3$, such that $L1\leq 0$. We study existence and properties of continuous solutions to the following problem \begin{equation}\label{00} Lu=φ(\cdot,u),% & \hbox{in $Ω$; in the sens of distribution;} \\ \end{equation} in $Ω ...

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Existence and concentration of ground state solutions for a Kirchhoff type problem
Electronic Journal of Differential Equations, 2016 This article concerns the Kirchhoff type problem $$\displaylines{ -\Big(\varepsilon^2a+\varepsilon b\int_{\mathbb{R}^3} |\nabla u|^2dx\Big)\Delta u +V(x)u= K(x)|u|^{p-1}u,\quad x\in \mathbb{R}^3,\cr u\in H^1(\mathbb{R}^3), }$$ where a,b are ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background General pediatricians often evaluate hematologic and oncologic presentations before subspecialty consultation, yet the 2025 Accreditation Council for Graduate Medical Education (ACGME) pediatric requirements reduce inpatient pediatric hematology/oncology (PHO) time, raising questions about resident readiness.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Germ cell tumors (GCTs) often arise in the ovaries and testes (extracranial) but can also develop in the brain (intracranial). We examined the relationship of individual, family, and community‐level socioeconomic status (SES) with stage of disease at diagnosis in a cohort of pediatric patients with GCT from Children's Oncology Group

Electronic Journal of Differential Equations, 2019 This article studies the existence and multiplicity of component-wise positive solutions for systems of nonlinear Hammerstein integral equations. In this system one nonlinear term is uniformly superlinear or uniformly sublinear, and the other is ...
