Cusp points and pitchfork interactions in equivariant bifurcation problems
Differential and Integral Equations, 1993 The relation between the concept of a cusp point for a mapping between Banach spaces and the interaction of two classical pitchfork bifurcations in equivariant spaces is considered. 2 parameter problems are considered by an approach based on linear normal form theory, Lyapunov-Schmidt reduction and restriction to solutions with appropriate isotropies ...

A normal form for excitable media
, 2006 We present a normal form for travelling waves in one-dimensional excitable media in form of a differential delay equation. The normal form is built around the well-known saddle-node bifurcation generically present in excitable media.

Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy
Advanced Materials Technologies, EarlyView.This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions

Nonlinear Magnetoconvection in a Sparsely Packed Porous Medium
International Journal of Geophysics, 2011 Linear and weakly nonlinear properties of magnetoconvection in a sparsely packed porous medium are investigated. We have obtained the values of Takens-Bogdanov bifurcation points and codimension two bifurcation points by plotting graphs of neutral curves

Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever
Advanced Materials Technologies, EarlyView.Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.

Prebifurcation noise amplification and noise-dependent hysteresis as indicators of bifurcations in nonlinear geophysical systems [PDF]
Nonlinear Processes in Geophysics, 2005 The phenomena of prebifurcation noise amplification and noise-dependent hysteresis are studied as prospective indicators of bifurcations ('noisy precursor') in nonlinear Geophysical systems. The phenomenon of prebifurcation noise amplification arises due
