Beam commissioning of a new compact scanned proton therapy system with four different dose calculation algorithms

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background The Central Japan International Medical Center (Gifu prefecture, Japan) as the 20th Proton Therapy Institution in Japan, has newly installed a compact scanned proton therapy system, ProBeam 360°™. We installed two commercial treatment planning systems (TPSs): Eclipse and RayStation.

Uniform isochronous centers of degrees 3 and 4 and their perturbations

open access: yes, 2015
En este trabajo se estudian los sistemas diferenciales polinomiales planos de grado 3 y 4 con un centro isócrono uniforme. Proporcionamos una clasificación para estos sistemas con respecto a la equivalencia topológica de sus retratos de fase globales en el disco de Poincaré.

Bifurcation of limit cycles from some uniform isochronous centers

open access: yes, 2015
This article concerns with the weak 16-th Hilbert problem. More precisely, we consider the uniform isochronous centers x'=-y x^(n-1) y, y'= x x^(n-2) y^2 , for n = 2, 3, 4, and we perturb them by all homogeneous polynomial of degree 2, 3, 4, respectively.
