Global solutions to a one-dimensional nonlinear wave equation derivable from a variational principle
This article focuses on a one-dimensional nonlinear wave equation which is the Euler-Lagrange equation of a variational principle whose Lagrangian density involves linear terms and zero term as well as quadratic terms in derivatives of the field.

Mitochondrial DNA disorders in neuromuscular diseases in diverse populations
Abstract Neuromuscular features are common in mitochondrial DNA (mtDNA) disorders. The genetic architecture of mtDNA disorders in diverse populations is poorly understood. We analysed mtDNA variants from whole‐exome sequencing data in neuromuscular patients from South Africa, Brazil, India, Turkey and Zambia. In 998 individuals, there were two definite

Existence of solutions for a variational unilateral system
In this work the authors study the existence of weak solutions of the nonlinear unilateral mixed problem associated to the inequalities $$ displaylines{ u_{tt}-M(| abla u| ^{2})Delta u+heta geq f, cr heta_t-Delta heta +u_tgeq g ,} $$ where $f$, $g$, $M ...

Heterozygous variants in AP4S1 are not associated with a neurological phenotype
Abstract Biallelic loss‐of‐function variants in AP4S1 cause childhood‐onset hereditary spastic paraplegia. A recent report suggested that heterozygous AP4S1 variants lead to a syndrome of lower limb spasticity and dysregulation of sphincter function. We critically evaluate this claim against clinical observations in 28 heterozygous carriers of the same

Handling rescue therapy in myasthenia gravis clinical trials: why it matters and why you should care
Abstract Myasthenia gravis (MG) clinical trials typically allow rescue therapy during follow‐up in the event of marked worsening of MG symptoms. Failure to appropriately address rescue therapy in defining treatment effects and planning statistical analyses may yield biased estimates, increase false positive rates, or decrease statistical power – all of

The influence of damping and source terms on solutions of nonlinear wave equations
We discuss in this paper some recent development in the study of nonlinear wave equations. In particular, we focus on those results that deal with wave equations that feature two competing forces.One force is a damping term and the other is a strong ...

Abstract Objectives Intravenous immunoglobulin (IVIg) is an effective treatment for Guillain–Barré syndrome (GBS), but recovery varies between patients. This study aims to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of a single and a second IVIg dose (SID) in patients with GBS.
