Bounded and Periodic Solutions of Semilinear Impulsive Periodic System on Banach Spaces

open access: yesFixed Point Theory and Applications, 2008
A class of semilinear impulsive periodic system on Banach spaces is considered. First, we introduce the T0-periodic PC-mild solution of semilinear impulsive periodic system.

Different Wave Structures for the (2+1)-Dimensional Korteweg-de Vries Equation

open access: yesAdvances in Mathematical Physics, 2022
In this article, a (2+1)-dimensional Korteweg-de Vries equation is investigated. Abundant periodic wave solutions are obtained based on the Hirota’s bilinear form and a direct test function.

Travelling wave solutions for the doubly dispersive equation using improved modified extended tanh-function method

open access: yesAlexandria Engineering Journal, 2022
In the present paper, the improved modified extended tanh-function method is employed to get new exact traveling wave solutions for the doubly dispersive model. Several types of solutions are obtained using the proposed method.

Periodic and asymptotically periodic solutions of neutral integral equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2000
Many results have been obtained for periodic solutions of Volterra integral equations (for instance, [1-3] and references cited therein). Here we consider two systems of neutral integral equations \begin{eqnarray} x(t)=a(t)+\int_0^t D(t,s,x(s))ds+\int_t^\

Higher order averaging theory for finding periodic solutions via Brouwer degree

open access: yes, 2014
In this paper we deal with nonlinear differential systems of the form where for i = 0, 1, …, k, and are continuous functions, and T-periodic in the first variable, D being an open subset of , and ε a small parameter.

Forced symmetry breaking perturbations for periodic solutions [PDF]

open access: yes, 1996
Using the formalism defined by R. Lauterbach and M. Roberts [21], we develop a geometric approach for the problem of forced symmetry breaking for periodic orbits in G-equivariant systems of ODE's.

Periodic solutions for evolution equations

open access: yesElectronic Journal of Differential Equations, 2002
We study the existence and uniqueness of periodic solutions for evolution equations. First we analyze the one-dimensional case. Then for arbitrary dimensions (finite or not), we consider linear symmetric operators.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.
