Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.Abstract The hypothalamic–pituitary–adrenal (HPA) axis is a vital neuroendocrine system that maintains homeostasis by regulating stress hormone secretion through tightly controlled circadian and ultradian rhythms. Although rodent studies and mathematical models have clarified the mechanisms of ultradian pulsatility, a quantitative, human‐specific ...

Fermionic quantization of Hopf solitons [PDF]
, 2006 In this paper we show how to quantize Hopf solitons using the Finkelstein-Rubinstein approach. Hopf solitons can be quantized as fermions if their Hopf charge is odd.

Stability and Hopf bifurcation on an SEIR delayed model with logistic growth [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2018 This paper investigates the stability and Hopf bifurcation of SEIR delay model with logistic growth. Firstly, the existence and uniqueness of equilibrium point are analyzed.

Bursting Oscillations in General Coupled Systems: A Review
Mathematics, 2023 In this paper, the bursting oscillation phenomenon in coupled systems with two time scales is introduced. Firstly, several types of bifurcation are briefly introduced: fold bifurcation, Hopf bifurcation, fold limit cycle bifurcation, homoclinic ...

Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.ABSTRACT We show that the removal of a type of reverse reactions preserves the absence of Hopf bifurcations in mass‐action reaction networks, or more precisely, the absence of single pairs of purely imaginary eigenvalues of the Jacobian of the system. The motivation is to answer the open question of whether the dual phosphorylation mechanism requiring ...

Bifurcation from a normally degenerate manifold
, 2010 Local bifurcation theory typically deals with the response of a degenerate but isolated equilibrium state or periodic orbit of a dynamical system to perturbations controlled by one or more independent parameters, and characteristically uses tools from ...

Empirical Assessment of Bifurcation Regions within New Keynesian Models [PDF]
As is well known in systems theory, the parameter space of most dynamic models is stratified into subsets, each of which supports a different kind of dynamic solution.

Anti-control of Hopf bifurcation for a chaotic system
Nonlinear EngineeringThe anti-control of Hopf bifurcation is a method used for bifurcation control. It can be used to realize the occurrence or delay of bifurcation at the specified position to meet the needs of engineering applications. In this study, a 4D chaotic system is

Engineering Reports, Volume 8, Issue 8, August 2026.An integrated hybrid energy storage and cogeneration system with CE‐DPS effectively stabilizes DC bus voltage in hydrogen fuel cell marine vessels. The proposed multi‐tier control suppresses voltage fluctuations, eliminates overshoot, and improves energy efficiency, achieving 68% exergy efficiency and 15.6% fuel savings.
