Period adding with the coexistence of successive at tract ing periodic orbit s is observed in the model of a chemical system when the bifurcation parameter is changed. This phenomenon is characterized by a family of one-dimensional return maps having a cusp shape with positive Schwarzian derivative that exhibits a saddle-node bifurcation.

A continuous dynamical system is presented in which the period -adding phenomenon is observed when a bifurcation parameter is changed . This phenomenon is characterized by a family of onedimensional return maps of a cusp shape which exhibits a saddle-node bifurcation .

The flame forming process is widely used to manufacture ship hull plates. The saddle-shaped surfaces have different curvatures in perpendicular angles of planes and the manufacturers face an anti-clastic curvature. In this article, the manufacturing of saddle-shaped surfaces utilizing the flame forming process is investigated. The spiral irradiating scheme is used for forming. In order to study...

Background: Saddle nose deformities mostly result from trauma. Most reports of saddle nose correction after trauma relate to isolated fractures, but in this article the experience of the authors is presented in relation to bone grafting for the correction of the saddle nose in multiple facial fracture patients. Objectives: The current study aimed to report the results of a protocol for choosing...

BACKGROUND Three-dimensional transthoracic echocardiography (3D-TTE) with dedicated software permits quantification of mitral annulus dynamics and papillary muscle motion throughout the cardiac cycle. METHODS AND RESULTS Mitral apparatus 3D-TTE was acquired in controls (n=42), patients with left ventricle dysfunction and functional mitral regurgitation (LVD-FMR; n=43) or without FMR (LVD-noMR...

INTRODUCTION Saddle nose deformity due to autoimmune diseases such as Wegener's Granulomatosis and Relapsing Polychondritis is aesthetically, functionally and psychologically distressing for patients. However, "reliable" options for surgical correction remain limited in the literature. We present our experience of augmentation rhinoplasty in this patient population focussing on the techniques a...

We show experimentally the scenario of a two-frequency torus T2 breakdown, in which a global bifurcation occurs due to the collision of a torus with an unstable periodic orbit, creating a heteroclinic saddle connection, followed by an intermittent behavior.

In order to accurately simulate the position of saddle in analysis and calculation a suspension bridge, then obtain accurate shape datum strand construction site, this paper puts forward method on geometric basis considering friction between main cable saddle. Firstly, is proposed formula deviation coordinates initial that equilibrium derived. Then, through theoretical derivation, program chang...

OBJECTIVE To evaluate a reproducible surgical technique for augmentation rhinoplasty of complex saddle nose deformities, which are characterized by substantial loss of nasal structural support and result in multiple nasal abnormalities. DESIGN Case series and surgical outcome study. SETTING Tertiary referral center. PATIENTS A total of 43 patients (32 female and 11 male; mean +/- SD age, ...
