A Standardized Technique for Ultrasound-MRI Fusion Imaging of the Carotid Artery for Vascular Assessment. [PDF]
J Ultrasound MedPurpose To describe a reproducible ultrasound–magnetic resonance imaging (MRI) fusion imaging technique developed for quantitative assessment of carotid wall strain and plaque morphology. Methods MRI volumes (Oblique T2 Cube) were imported into the Sequoia ultrasound system equipped with an electromagnetic tracking module.

Non-degenerate umbilics, the path formulation and gradient bifurcation problems [PDF]
, 2004 Parametrised contact-equivalence is successful for the understanding and classification of the qualitative local behaviour of bifurcation diagrams and their perturbations. Path formulation is an alternative point of view.

Experiments and modelling of rate-dependent transition delay in a stochastic subcritical bifurcation [PDF]
Royal Society Open Science, 2018 Complex systems exhibiting critical transitions when one of their governing parameters varies are ubiquitous in nature and in engineering applications. Despite a vast literature focusing on this topic, there are few studies dealing with the effect of the

Arnol′d tongues arising from a grazing-sliding bifurcation [PDF]
, 2009 The Neımark–Sacker bifurcation, or Hopf bifurcation for maps, is a well-known bifurcation for smooth dynamical systems. At this bifurcation a periodic orbit loses stability, and, except at certain “strong” resonances, an invariant torus is born.

Bifurcation Scenario to Nikolaevskii Turbulence in Small Systems [PDF]
Journal of the Physical Society of Japan, 2005 We show that the chaos in Kuramoto-Sivashinsky equation occurs through period-doubling cascade (Feigenbaum scenario), in contrast, the chaos in Nikolaevskii equation occurs through torus-doubling bifurcation (Ruelle-Takens-Newhouse scenario).

Local and global bifurcation phenomena [PDF]
, 1983 Bifurcation, global non-uniqueness and stability of solutions to the plane-strain problem of an incompressible isotropic elastic material subject to in-plane dead-load tractions are considered.

Periodic patterns displace active phase separation
New Journal of Physics, 2021 In this work we identify and investigate a novel bifurcation in conserved systems. This secondary bifurcation stops active phase separation in its nonlinear regime. It is then either replaced by an extended, system-filling, spatially periodic pattern or,
