Periodic attractors of perturbed one-dimensional maps [PDF]

open access: yes, 2013
In this paper we investigate how many periodic attractors maps in a small neighbourhood of a given map can have. For this purpose we develop new tools which help to make uniform cross-ratio distortion estimates in a neighbourhood of a map with degenerate

Bifurcations in the regularized Ericksen bar model

open access: yes, 2007
We consider the regularized Ericksen model of an elastic bar on an elastic foundation on an interval with Dirichlet boundary conditions as a two-parameter bifurcation problem.

Bifurcation strategies using second-generation drug-eluting stents on clinical outcomes in diabetic patients

open access: yesFrontiers in Cardiovascular Medicine, 2022
BackgroundDiabetes mellitus (DM) is a critical risk factor for the pathogenesis and progression of coronary artery disease, with a higher prevalence of complex coronary artery disease, including bifurcation lesions.

Steady-state solutions of a mass-conserving bistable equation with a saturating flux

open access: yes, 2012
We consider a mass-conserving bistable equation with a saturating flux on an interval. This is the quasilinear analogue of the Rubinstein–Steinberg equation, suitable for description of order parameter conserving solid–solid phase transitions in the case

Bifurcation dynamics of Sherman neuron under magnetic flow effect

open access: yesJournal of Measurement Science and Instrumentation, 2023
The bifurcation behavior of Sherman neuron system under the influence of magnetron memristor is analyzed. Taking the membrane potential reversal voltages VCa and VK of islet β-cell neuron model as bifurcation parameters, the inter-spike interval ...

Interval of restitution coefficient for chattering in impact damper

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2022
Based on the impact damper, a dynamic model of a non-fixed constrained collision system was established. The coefficient of restitution is used as the main control parameter to analyze the system’s periodic movement and its bifurcation region.

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.

Global Bifurcation from Intervals for the Monge-Ampère Equations and Its Applications [PDF]

open access: yesJournal of Function Spaces, 2018
We shall establish the global bifurcation results from the trivial solutions axis or from infinity for the Monge-Ampère equations: det(D2u)=λm(x)-uN+m(x)f1(x,-u,-u′,λ)+f2(x,-u,-u′,λ), in B, u(x)=0, on ∂B, where D2u=(∂2u/∂xi∂xj) is the Hessian matrix of u, where B is the unit open ball of RN, m∈C(B¯,[0,+∞)) is a radially symmetric weighted function and ...

Bifurcation and chaos in a host-parasitoid model with a lower bound for the host

open access: yesAdvances in Difference Equations, 2018
In this paper, a discrete-time biological model and its dynamical behaviors are studied in detail. The existence and stability of the equilibria of the model are qualitatively discussed.

Comparing the clinical outcomes of single vs. systematic dual stenting strategies for unprotected left main bifurcation lesion: a systematic review and meta-analysis

open access: yesFrontiers in Cardiovascular Medicine, 2023
IntroductionThe optimal percutaneous coronary intervention (PCI) strategy for coronary left main (LM) bifurcation lesions remains controversial. This meta-analysis compared the medium and long-term follow-up clinical outcomes of single vs.
