background: closure of patent ductus arteriosus (pda), ventricular septal defect (vsd) and atrial septal defect (asd) can be done surgically or by device. this study was designed to compare the total cost of surgical or device closures of pda, asd or vsd for iranian patients. methods: this is a cross-sectional study, conducted from january 1, 2005 until january 1, 2006 in two large heart center...

this is a case presentation of a 26-year-old woman with a moderate-sized atrial septal secundum defect (17mm) who underwent catheterism, during which an amplatzer septal occluder number 26 was inserted successfully. on the second postoperative day, she deteriorated and a clinical examination showed a typical tamponade. after a percutaneous aspiration of the pericardial cavity and transient impr...

BACKGROUND The use of rest surface EMG of jaw elevator muscles is still debated. The low voltage recorded in anterior temporalis muscle by electromyography (EMG) in rest position could be affected by electronic noise or by activity coming from other muscles. Our goal was to evaluate the physiological behaviour of the anterior temporalis by surface EMG at rest mandible position during open or cl...

The new isometric mapping dimensionality reduction algorithm with Incremental Generalized Regression Network has been primarily recognized for stripe surface defects images with the typical characteristics of complex texture, non-uniform image size, asymmetrical number of sample classes, variation illumination environment. This method is suitable to resolve the problem of “short circuit”, store...

We study the superconformal index of the N = 4 super-Yang-Milles theory on S 3 × S1 with the half BPS superconformal surface operator (defect) inserted at the great circle of S3. The half BPS superconformal surface operators preserve the same supersymmetry as well as the symmetry of the chemical potential used in the definition of the superconformal index, so the structure and the parameterizat...

A formulation of the scattering-matrix method for calculating localized modes at any type of planar defect has been given by Achar and Barsch' and applied to the problem of determining the surface modes of a semi-infinite NaCl crystal. Here we will consider only the application of this formulation when the defect is a surface. Similar criticisms hold for other types of defects. Achar and Barsch...
