Bifurcation of limit cycles for a class of quintic Hamiltonian systems with quartic perturbed terms
上海师范大学学报. 自然科学版, 2022 By using the method of detection function and numerical calculation, the bifurcation of limit cycles for a class of quintic Hamiltonian systems under quartic perturbations was studied.

Dynamic analysis of unilateral diffusion Gompertz model with impulsive control strategy
Advances in Difference Equations, 2018 In this paper, we establish a unilateral diffusion Gompertz model of a single population in two patches in a theoretical way. Firstly, we prove the existence and uniqueness of an order-one periodic solution by the geometry theory of differential ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
