Stability and bifurcation of equilibrium solutions of reaction-diffusion equations on an infinite space interval

Journal of Differential Equations, 1984
The author studies stability and bifurcation properties of equilibrium solutions of the problem \[ u_t=u_{xx}+f(x,u,u_x,\alpha),\quad u_x(-\infty,t)=u_x(\infty,t)=0, \tag{*} \] with \(\alpha\) being a real bifurcation parameter. To this end, he writes (*) as operator equation \(du/dt=G(u,\alpha)\) in appropriate function spaces, and studies the Fréchet

Intergenerational transmission of anxiety: A comparison of transdiagnostic and disorder‐specific pathways

JCPP Advances, EarlyView.
Abstract Background Individuals with a parental history of anxiety disorders are at risk of developing an anxiety disorder. Prior studies have focused on the transmission of specific anxiety disorders across generations (i.e., disorder‐specific transmission), often overlooking the possibility that a general tendency to develop various forms of anxiety ...

Interspike interval statistics of the neurons that exhibit the supercritical Hopf bifurcation [PDF]

, 2008
We evaluated statistical characteristics of spike trains of neurons that exhibit a supercritical Hopf bifurcation by higher order statistical coefficients, a coefficient of variation and a coefficient of skewness, and showed that the estimated ...

COHERENCE RESONANCE–INDUCED STOCHASTIC NEURAL FIRING AT A SADDLE-NODE BIFURCATION

, 2011
Coherence resonance at a saddle-node bifurcation point and the corresponding stochastic firing patterns are simulated in a theoretical neuronal model. The characteristics of noise-induced neural firing pattern, such as exponential decay in histogram of ...

Standardized MRI‐Based Quantification of Epicardial Adipose Tissue Volume: Reproducibility and Agreement With Cardiac Computed Tomography

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Epicardial adipose tissue volume (EATV) is increasingly recognized as a cardiometabolic risk marker associated with adverse outcomes. The most established approach for EATV quantification is cardiac computed tomography (CT). MRI offers a radiation‐free alternative allowing simultaneous assessment of myocardial function and tissue ...

Global bifurcation for semilinear eigenvalue problems involving nonlocal terms

Electronic Journal of Differential Equations
We investigate global bifurcation phenomenon for a class of semilinear eigenvalue problems involving nonlocal terms. Under certain assumptions, we demonstrate the existence of a global continuum emanating from the first eigenvalue of the unperturbed ...

Degenerate Hopf Bifurcation and Isolas of Periodic Solutions in an Enzyme-Catalyzed Reaction Model

, 1993
A point of degenerate Hopf bifurcation in an enzyme-catalyzed model is rigorously analyzed by using techniques of singularity theory and interval analysis.

Anatomy of the Lisfranc joint complex: An illustrated review with surgical approach

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract This manuscript presents a detailed anatomical review of the Lisfranc joint complex, which includes the tarsometatarsal joints, the intertarsal joints and the proximal intermetatarsal joints. From the bony anatomy to the ligamentous structures reaching the base of the second metatarsal and the surgical anatomy relevant to fix the joint complex,

Period 3 Bifurcation for the Logistic Mapping

, 1982
In the context of continuous mappings of the interval, one of the most striking features may be Sharkovsky's theorem [6] which, among other thing, shows that the existence of a period 3 point implies the existence of periodic points of every period (see ...

Navicular and fifth metatarsal base stress fractures: An illustrated anatomical review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract The navicular bone and the proximal fifth metatarsal (M5) play a vital role in maintaining the structural integrity and biomechanical stability of the foot's medial and lateral columns, respectively. Both bones' unique anatomical configuration, intricate mechanical environment and limited vascular supply make specific locations particularly ...
