Bifurcation Analysis of Nonlinear Oscillations in the Electrical Activity of Pancreatic β‐Cells
PAMM, Volume 25, Issue 4, December 2025.ABSTRACT Cell biological systems are characterized by complex relationships and nonlinear processes. The modeling of these processes improves the understanding, and represents a significant enrichment of the experimental investigation. An example of such a system is the regulation of blood glucose concentration by pancreatic β$\beta$‐cells through the ...

Kaldor, Hicks and Goodwin Meet the Supermultiplier: On Growth Cycles and Autonomous Demand
Metroeconomica, Volume 76, Issue 4, Page 545-556, November 2025.ABSTRACT This paper presents an approach to reconciling short‐run business cycles with long‐run growth in macroeconomic models. It addresses recent criticisms of supermultiplier models by developing a framework that combines investment‐driven cycles with autonomous demand‐led growth in the long run.

Hopf Bifurcation Control in a FAST TCP and RED Model via Multiple Control Schemes
Journal of Control Science and Engineering, 2016 We focus on the Hopf bifurcation control problem of a FAST TCP model with RED gateway. The system gain parameter is chosen as the bifurcation parameter, and the stable region and stability condition of the congestion control model are given by use of the

Pattern Formation and Nonlinear Waves Close to a 1:1 Resonant Turing and Turing–Hopf Instability
Studies in Applied Mathematics, Volume 155, Issue 5, November 2025.ABSTRACT In this paper, we analyze the dynamics of a pattern‐forming system close to simultaneous Turing and Turing–Hopf instabilities, which have a 1:1 spatial resonance, that is, they have the same critical wave number. For this, we consider a system of coupled Swift–Hohenberg equations with dispersive terms and general, smooth nonlinearities.
