Global positive periodic solutions of periodic n-species competition systems
Journal of Mathematical Analysis and Applications, 2009 Lotka-Volterra systems have been investigated extensively for the last decades. Many results dealing with the global existence and attractivity of periodic solutions have been obtained. As an extension of the Lotka-Volterra models in 1973, a more complicated model was proposed by Gilpin and Ayala.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Chemotherapy‐induced peripheral neuropathy remains a major complication in pediatric cancer, with disrupted somatosensory and nociceptive processing being a key aspect. This review synthesizes empirical studies on alterations in somatosensory and nociceptive processing in children and adolescents with cancer.

Weak and strong singularities problems to Liénard equation
Boundary Value Problems, 2020 This paper is devoted to an investigation of the existence of a positive periodic solution for the following singular Liénard equation: x ″ + f ( x ( t ) ) x ′ ( t ) + a ( t ) x = b ( t ) x α + e ( t ) , $$ x''+f\bigl(x(t)\bigr)x'(t)+a(t)x= \frac{b(t)}{x^

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.

Advances in Difference Equations, 2020 In this paper, we study the eventual periodicity of the fuzzy max-type difference equation x n = max { C , x n − m − k x n − m } , n ∈ { 0 , 1 , … } $x_{n} =\max \{C , \frac{x_{n-m-k}}{x_{n-m} }\}, n\in \{0,1,\ldots \} $ , where m and k are positive ...

Subharmonic bouncing solutions of generalized Lazer–Solimini equation
Electronic Journal of Qualitative Theory of Differential Equations, 2021 The paper deals with the singular differential equation $x'' + g(x) = p(t)$, with $g$ having a weak singularity at $x=0$ and $2\pi$-periodic function $p$.

On existence of positive periodic solutions
Monatshefte f�r Mathematik, 1998 Let \(\Omega\) be an open convex subset of \(\mathbb{R}^n\). A differential equation \[ \dot x=f(t,x) \tag{1} \] on \(\mathbb{R}\times \text{cl} \Omega\) is considered. It is assumed that the right-hand side of (1) is \(T\)-periodic in \(t\). The main theorem asserts the existence of a fixed point of the Poincaré map associated to (1) in \(\Omega ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Chemoimmunotherapy with irinotecan, temozolomide, and dinutuximab (I/T/DIN) has emerged as first‐line therapy for relapsed/refractory (r/r) high‐risk neuroblastoma (HRNB) in North America. Topotecan and cyclophosphamide (T/C) are often used in combination with dinutuximab in the setting of lack of response, progression, or incomplete ...

Discrete Dynamics in Nature and Society, 2006 A nonautonomous semiratio-dependent predator-prey system with nonmonotonic functional responses is investigated. For general nonautonomous case, positive invariance, permanence, and globally asymptotic stability for the system are studied.

Dynamical behaviors of a two-competitive metapopulation system with impulsive control
Advances in Difference Equations, 2017 In this paper, we study the dynamical behaviors of a two-competitive metapopulation system with impulsive control and focus on the stable coexistence of the superior and inferior species.
