Grooved Surface of the Obturator Internus Muscle With Two Distinct Adjacent Parts

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The specific anatomical features of the obturator internus, particularly those of its medial surface, remain insufficiently characterized. This study investigated the morphology of the obturator internus muscle by focusing on the shape of its medial surface and potential age‐related changes.

Bilateral Symmetry and Variation of Recurrent Laryngeal Nerve and Inferior Thyroid Artery Patterns: An Intraoperative Study of 150 Nerves

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The anatomical relationship of the inferior thyroid artery (ITA) and the recurrent laryngeal nerve (RLN) is highly variable. This study aims to evaluate bilateral RLN branching patterns and their relationship to the ITA within the same patient, predicting contralateral anatomical variations and ultimately reducing intraoperative risk of RLN ...

A Novel Anatomical Description of the Normal Terminal Fibular Artery and the Terminal Fibular Window: Radiological Findings and Surgical Implications

open access: yesClinical Anatomy, EarlyView.
ABSTRACT A novel anatomical description and radiological finding, related to the anatomical course of the terminal fibular artery (FibA) was recently reported. In the article, the authors found the terminal FibA to change its course, from being posterior and medial to the fibula to surface anteriorly and laterally before residing below the tibiofibular

Analysis of a bifurcation problem

Mathematics and Computers in Simulation, 2002
A bifurcation problem of the type \(u-\lambda Lu+g(\lambda,u,y)=0\) in a neighborhood of a particular solution \((\lambda_0,0,0)\in \mathbb{R}\times E\times F\) is considered. Here \(E, F\) are real Banach spaces and \(\lambda_0\) is a semisimple characteristic number of the linear operator \(L\).

On the analysis of hopf bifurcations

International Journal of Engineering Science, 1983
Abstract The oscillatory instability and the family of limit cycles associated with a general autonomous dynamical system described by n nonlinear first order differential equations and an independently assignable scalar parameter are examined via an intrinsic method of harmonic analysis.

AN ANALYSIS OF IMPERFECT BIFURCATION*

Annals of the New York Academy of Sciences, 1979
In this article we outline an application of the Thorn-Mather singularity theory of C" mappings to a problem in bifurcation theory. A detailed description of the results stated here may be found in Reference 1. Unless otherwise stated all mappings are assumed to be germs of C a functions near the origin. map G: IR" x IR - IR"'

BIFURCATION ANALYSIS OF CHEN'S EQUATION

International Journal of Bifurcation and Chaos, 2000
Anticontrol of chaos by making a nonchaotic system chaotic has led to the discovery of some new chaotic systems, particularly the continuous-time three-dimensional autonomous Chen's equation with only two quadratic terms. This paper further investigates some basic dynamical properties and various bifurcations of Chen's equation, thereby revealing its ...

BIFURCATION ANALYSIS OF AN AMPLITUDE EQUATION

International Journal of Bifurcation and Chaos, 2013
We study the bifurcation and stability of constant stationary solutions (u0, v0) of a particular system of parabolic partial differential equations as amplitude equations on a bounded domain (0, L) with Neumann boundary conditions. In this paper, the asymptotic behavior of the solutions (u0, v0) of the amplitude equations are considered.
