The Lazer McKenna conjecture for radial solutions in the RN ball
Electronic Journal of Differential Equations, 1993 nonlinearity contains the first $k$ eigenvalues of the linear part and a certain parameter is large, we establish the existence of 2k radial solutions to a semilinear boundary value problem.

FEBS Open Bio, EarlyView.Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

四川大学学报. 自然科学版, 2021 We consider the existence of positive radial solutions to a class of elliptic boundary value problem with gradient term. The existence of positive radial solutions is obtained by using the Leray-Schauder fixed point theorem.

Infinitely Many Radial and Non-Radial Solutions for a Class of Hemivariational Inequalities
Rocky Mountain Journal of Mathematics, 2005 This paper deals with the study of the following class of hemivariational inequalities: find \(u\in H^1(\mathbb R^N)\) such that \[ \int_{\mathbb R^N}(\nabla u\nabla w+uw)dx+\int_{\mathbb R^N}F^0_x(x,u(x);-w(x))dx\geq 0, \] for all \(w\in H^1(\mathbb R^N)\), where \(F^0\) stands for the generalized directional derivative in the sense of Clarke.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Optimal energy growth lower bounds for a class of solutions to the vectorial Allen-Cahn equation [PDF]
, 2014 We prove optimal lower bounds for the growth of the energy over balls of minimizers to the vectorial Allen-Cahn energy in two spatial dimensions, as the radius tends to infinity. In the case of radially symmetric solutions, we can prove a stronger result

Large radial solutions of a polyharmonic equation with superlinear growth
Electronic Journal of Differential Equations, 2007 This paper concerns the equation $Delta!^m u=|u|^p$, where $minmathbb{N}$, $pin(1,infty)$, and $Delta$ denotes the Laplace operator in $mathbb{R}^N$, for some $Ninmathbb{N}$. Specifically, we are interested in the structure of the set $mathcal{L}$ of all

Asymptotic Solutions of Serial Radial Fuel Shuffling
Energies, 2015 In this paper, the mechanism of traveling wave reactors (TWRs) is investigated from the mathematical physics point of view, in which a stationary fission wave is formed by radial fuel drifting. A two dimensional cylindrically symmetric core is considered

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.
