Neimark-Sacker Bifurcation Analysis for a Discrete-Time System of Two Neurons
Abstract and Applied Analysis, 2012 A class of discrete-time system modelling a network with two neurons is considered. First, we investigate the global stability of the given system. Next, we study the local stability by techniques developed by Kuznetsov to discrete-time systems.

On Global Bifurcation of Variational Inequalities and Applications
Journal of Differential Equations, 1997 The article is the continuation of the author's earlier work [\textit{V. K. Le}, J. Differ. Equations 131, No. 1, 39-78 (1996; Zbl 0863.49008)] where a general topological degree approach for bifurcation problems concerning variational inequalities was proposed.

Advanced Science, EarlyView.ABSTRACT Background Therapeutic resistance limits durable survival in advanced/metastatic renal cell carcinoma (RCC) treated with first‐line tyrosine kinase inhibitor (TKI) plus immune checkpoint inhibitor (ICI). We sought to define key resistance drivers and actionable targets.

A global index for bifurcation of fixed points.
Journal für die reine und angewandte Mathematik (Crelles Journal), 1988 Let \(X\) be a Banach space, \(\mathcal O\subset\mathbb R^ k\times X\) be open and \(f: \mathcal O\to X\) be completely continuous such that \(f(\lambda,0)=0\) for all \(\lambda\). If the set \[ \mathcal B:=\mathbb R^ k\cap \text{clos}\{(\lambda,x)\in\mathcal O: f(\lambda,x)=x\neq 0 \} \] of bifurcation points is compact an index \(\mathrm{BI}(f)\) is ...

Exceptional Antimodes in Multi‐Drive Cavity Magnonics
Advanced Electronic Materials, EarlyView.Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Bifurcation of a Cohen-Grossberg Neural Network with Discrete Delays
Abstract and Applied Analysis, 2012 A simple Cohen-Grossberg neural network with discrete delays is investigated in this paper. The existence of local Hopf bifurcations is first considered by choosing the appropriate bifurcation parameter, and then explicit formulas are given to determine ...

Global bifurcation from intervals for Sturm-Liouville problems which are not linearizable
Electronic Journal of Qualitative Theory of Differential Equations, 2013 In this paper, we study unilateral global bifurcation which bifurcates from the trivial solutions axis or from infinity for nonlinear Sturm--Liouville problems of the form \begin{equation} \left\{ \begin{array}{l} -\left(pu'\right)'+qu=\lambda au+af\left(

Additive Global Noise Delays Turing Bifurcations
Physical Review Letters, 2007 We apply a stochastic center manifold method to the calculation of noise-induced phase transitions in the stochastic Swift-Hohenberg equation. This analysis is applied to the reduced mode equations that result from Fourier decomposition of the field variable and of the temporal noise. The method shows a pitchfork bifurcation at lower perturbation order,
