Existence and multiplicity of solutions for a quasilinear system with locally superlinear condition

open access: yesAdvances in Nonlinear Analysis, 2023
We investigate the existence and multiplicity of weak solutions for a nonlinear Kirchhoff type quasilinear elliptic system on the whole space RN{{\mathbb{R}}}^{N}. We assume that the nonlinear term satisfies the locally super-(m1,m2)\left({m}_{1},{m}_{2})

A randomised, double‐blinded comparison between subcutaneous rush and intralympathic allergen immunotherapy induction in atopic dogs

open access: yesVeterinary Dermatology, Volume 34, Issue 2, Page 91-98, April 2023., 2023
Background – Atopic dermatitis (AD) is one of the most common skin diseases in small animal practice. Allergen immunotherapy (AIT) is the only curative treatment for the disease, and oral, subcutaneous and intralymphatic administration of allergens are commonly employed.

A global compactness result with applications to a Hardy-Sobolev critical elliptic system involving coupled perturbation terms

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we study a Hardy-Sobolev critical elliptic system involving coupled perturbation terms: (0.1)−Δu+V1(x)u=η1η1+η2∣u∣η1−2u∣v∣η2∣x′∣+αα+βQ(x)∣u∣α−2u∣v∣β,−Δv+V2(x)v=η2η1+η2∣v∣η2−2v∣u∣η1∣x′∣+βα+βQ(x)∣v∣β−2v∣u∣α,\left\{\begin{array}{c}-\Delta u+

Maternal mental health and infant neurodevelopment at 6 months in a low‐income South African cohort

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 43, Issue 6, Page 849-863, November 2022., 2022
Abstract Maternal mental health disorders and the adverse consequences for infant neurodevelopment have received substantial research attention in high‐income countries over the past five decades. In Africa, where relatively little work has been done on this topic, researchers have largely focused on infant physical health outcomes.

Existence results for a fourth order partial differential equation arising in condensed matter physics [PDF]

open access: yes, 2015
We study a higher order parabolic partial differential equation that arises in the context of condensed matter physics. It is a fourth order semilinear equation whose nonlinearity is the determinant of the Hessian matrix of the solution. We consider this
