A global existence result for the anisotropic magnetohydrodynamical systems

open access: yes, 2016
We study an anisotropic system arising in magnetohydrodynamics (MHD) in the whole space R^3 , in the case where there are no diffusivity in the vertical direction and only a small diffusivity in the horizontal direction (of size $\epsilon$$\alpha$ with 0

EXISTENCE RESULTS FOR SEMILINEAR DIFFERENTIAL EQUATIONS

open access: yesJournal of the Korean Mathematical Society, 2002
The authors consider the following semilinear differential equation in a Banach space \(X\) \[ \frac{d}{dt}[x(t)+g(t,x(t)]=Ax(t)+f(t,x(t)), \quad t\in J=[0,b],\;x(0)=x_{0}, \tag{1} \] where \(x:J\rightarrow X,A\) is the infinitesimal generator of a strongly continuous semigroup of bounded linear operators \(\{T(t)\); \(t\geq0\}\) on \(X,f:J\times X ...

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Anisotropic equations: Uniqueness and existence results

open access: yesDifferential and Integral Equations, 2008
We study uniqueness of weak solutions for elliptic equations of the following type \[ -\partial_{x_{i}}\left( a_{i}(x,u)\left\vert \partial_{x_{i}}u\right\vert ^{p_{i}-2}\partial_{x_{i}}u\right) +b(x,u) =f(x), \] in a bounded domain $\Omega\subset{\mathbb{R}}^{n}$ with Lipschitz continuous boundary $\Gamma=\partial\Omega$.

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Existence results for differential delay equations—II

open access: yesNonlinear Analysis: Theory, Methods & Applications, 1991
[For part I see J. Differ. Equations 102, No. 2, 342-359 (1993; Zbl 0782.34068), reviewed above.] Systems of differential-difference equations of the form \[ y^{(k)}(t)=F(t,y(s_{11}(t)),\ldots,y(s_{1m_ 1}(t)),\ldots,y^{(k-1)}(s_{k1}(t)),\ldots,y^{(k-1)}(s_{km_ k}(t))),\tag{1} \] \(t\in[0,T]\), are considered. The delays satisfy \(s_{ij}(t)\leq t\), \(F\

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding

An Existence Result for Nonlinear Fractional Differential Equations on Banach Spaces

open access: yesBoundary Value Problems, 2009
The aim of this paper is to investigate a class of boundary value problem for fractional differential equations involving nonlinear integral conditions. The main tool used in our considerations is the technique associated with measures of noncompactness.

An Existence Result for Second-Order Impulsive Differential Equations with Nonlocal Conditions

open access: yesDiscrete Dynamics in Nature and Society, 2010
The Leray-Schauder alternative is used to investigate the existence of solutions for second-order impulsive differential equations with nonlocal conditions in Banach spaces. The results improve some recent results.

A general existence result for isothermal two-phase flows with phase transition

open access: yes, 2018
Liquid-vapor flows with phase transitions have a wide range of applications. Isothermal two-phase flows described by a single set of isothermal Euler equations, where the mass transfer is modeled by a kinetic relation, have been investigated analytically
