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 ...

Harnessing Phase Separation for the Development of High‐Performance Hydrogels
Advanced Science, EarlyView.ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Critical dynamics and cyclic memory retrieval in non-reciprocal Hopfield networks
SciPost PhysicsWe study Hopfield networks with non-reciprocal coupling inducing switches between memory patterns. Dynamical phase transitions occur between phases of no memory retrieval, retrieval of multiple point-attractors, and limit-cycles. The limit cycle phase is

Global dynamics and bifurcation analysis of a host–parasitoid model with strong Allee effect
Journal of Biological Dynamics, 2017 In this paper, we study the global dynamics and bifurcations of a two-dimensional discrete time host–parasitoid model with strong Allee effect. The existence of fixed points and their stability are analysed in all allowed parametric region.

Folded Bifurcation in Coupled Asymmetric Logistic Maps [PDF]
Progress of Theoretical Physics, 1995 A system of coupled two logistic maps, one periodic and the other chaotic, is studied. It is found that with the variation of the coupling strength, the system displays several curious features such as the appearance of quadrupling of period, occurrence of isolated period three attractor and the coexistence of the Hopf and pitchfork bifurcations ...

Global Hopf bifurcation in the ZIP regulatory system [PDF]
, 2015 Regulation of zinc uptake in roots of Arabidopsis thaliana has recently been modeled by a system of ordinary differential equations based on the uptake of zinc, expression of a transporter protein and the interaction between an activator and inhibitor ...

Analysis of a quadratic system obtained from a scalar third order differential equation
Electronic Journal of Differential Equations, 2010 In this article, we study the nonlinear dynamics of a quadratic system in the three dimensional space which can be obtained from a scalar third order differential equation.

Advanced Science, EarlyView.Boiling Histrotripsy (BH), a mechanical form of focused ultrasound (FUS), allows for non‐invasive and non‐ionizing tissue destruction. Utilizing a BH treatment protocol that yielded bifurcating primary tumor growth responses, we found that immediate BH‐induced tumor growth control identifies tumors with acute reductions in antigen‐presenting cells (APC)
