Global phase portraits of some reversible cubic centers with noncollinear singularities

, 2021
Agraïments: The first author also is supported by the Ramón y Cajal grant number RYC-2011-07730.The results in this paper show that the cubic vector fields ˙x = −y + M(x, y) − y(x2 + y2), y˙ = x + N(x, y) + x(x2 + y2), where M, N are quadratic ...

Framing National Education in Hong Kong: A frame analysis of power dynamics in stakeholders' competing narratives

British Educational Research Journal, EarlyView.
Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Qualitative Analysis of a Density-Dependent Prey–Predator Model with Holling Type III Functional Responses

Mathematics
This research examines the behavioral shifts within a discrete-time predator–prey framework, constructed by applying the forward Euler discretization to a continuous model. The system incorporates Smith’s growth dynamics for the prey population alongside

Leaving children behind for cross‐border education: Unveiling the emotional agency of international post‐graduate student mothers

British Educational Research Journal, EarlyView.
Abstract Despite growing interest in the internationalisation of higher education, the experiences of international student parents, particularly international student mothers, remain largely marginalised in research and policy. This paper examines the emotional agency of international student mothers who leave their children behind in their home ...

A Neural Residual Correction of the Explicit Euler Method via Learned Truncation Error Operators: A Lotka–Volterra Case Study

Mathematics
The explicit Euler method is widely used for the numerical integration of ordinary differential equations due to its simplicity and low computational cost; however, its accuracy and long-term qualitative behavior deteriorate for nonlinear oscillatory ...
