Non-degenerate umbilics, the path formulation and gradient bifurcation problems [PDF]

open access: yes, 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.

Local and global bifurcation phenomena [PDF]

open access: yes, 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.

Clinical Outcomes of Proximal Optimization Technique (POT) in Bifurcation Stenting Short title: Impact of proximal optimization technique [PDF]

open access: yes, 2021
Background: Optimal deployment of coronary stents in a bifurcation lesion remains a matter of debate.Aims: We sought to capture the daily practice of bifurcation stenting by means of a worldwide registry and to investigate how the post-implantation ...

On bifurcation intervals for nonlinear eigenvalue problems [PDF]

open access: yesAnnales Polonici Mathematici, 1999
Summary: We give a sufficient condition for \([\mu- M,\mu+ M]\times \{0\}\) to be a bifurcation interval of the equation \(u= L(\lambda u+ F(u))\), where \(L\) is a linear symmetric operator in a Hilbert space, \(\mu\in r(L)\) is of odd multiplicity, and \(F\) is a nonlinear operator.

Middle cerebral artery bifurcation aneurysms are associated with patient age, sex, bifurcation angle, and vascular diameters

open access: yesScientific Reports, 2023
To investigate the relationship of the middle cerebral artery (MCA) bifurcation aneurysms with patients’ age and sex, vascular angles at the bifurcation, and diameters of the M1 and two M2 arteries, patients with and without MCA aneurysms were ...

Debate: Percutaneous revascularization strategies for distal left main coronary artery disease. Approach from the DKCRUSH-V trial

open access: yesREC: Interventional Cardiology (English Ed.), 2022
QUESTION: What aspects do you think might explain the significant differences reported between the results from the EBC MAIN (European bifurcation club left main coronary stent study),1 and the DKCRUSH-V (Double kissing crush vs provisional stenting for ...

A global bifurcation theorem for a multiparameter positone problem and its application to the one-dimensional perturbed Gelfand problem

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
We study the global bifurcation and exact multiplicity of positive solutions for \begin{equation*} \begin{cases} u^{\prime \prime }(x)+\lambda f_{\varepsilon }(u)=0\text ...

Reduced basis method applied to a convective stability problem

open access: yesJournal of Mathematics in Industry, 2018
Numerical reduced basis methods are instrumental to solve parameter dependent partial differential equations problems in case of many queries. Bifurcation and instability problems have these characteristics as different solutions emerge by varying a ...
