Large bifurcation supports [PDF]

open access: yesarXiv, 2018
In the study of global bifurcations of vector fields on $S^2$, it is important to distinguish a set "where the bifurcation actually occurs", -- the bifurcation support. Hopefully, it is sufficient to study the bifurcation in a neighborhood of the support only. The first definition of bifurcation support was proposed by V.Arnold.

Symmetry analysis, bifurcation and exact solutions of nonlinear wave equation in semiconductors with strong spatial dispersion

open access: yesElectronic Journal of Differential Equations, 2017
Based on Lie symmetry analysis and steady bifurcation method, we study the nonlinear wave equation in semiconductors with strong spatial dispersion.

About stability analysis of elastic frames [PDF]

open access: yesИнженерно-строительный журнал, 2012
This article illustrates a simple method of stability analysis for elastic frames loaded with dead and follow forces. In its undisturbed state, frame elements might undergo not compression only but bending and torsion as well. It is shown that for simple

Differential Long-Term Effects of First- and Second-Generation DES in Patients With Bifurcation Lesions Undergoing PCI

open access: yesJACC: Asia, 2021
Background: There is a paucity of data regarding the long-term clinical outcomes of first- versus second-generation drug-eluting stent (DES), especially when used to treat complex lesions such as bifurcation lesions.

Mechano-chemical dynamics of active gels: interplay between spatial bistability and volume variations

open access: yesJournal of the Mechanical Behavior of Materials, 2011
The mechano-chemical dynamics of a spherical bead of gel immersed in an autocatalytic bistable chemical reaction are examined. The spheres exhibit autonomous volume self-oscillation dynamics.
