The paper presents a new reduction method designed for dynamic contact problems. Recently, we have proposed an efficient scheme the node-to-node formulation, that leads to Linear Complementarity Problems (LCP). Here, enhance underlying problem node-to-segment formulation. Due application of dual approach, Nonlinear Problem (NCP) is obtained, where condition described by quadratic inequality and...

conclusions in surgery for facial nerve neuroma in the mastoid segment, it is better not to rely on imaging alone; all facial nerves from the geniculate ganglion to the styloid foramen become exposed for tumor removal. case presentation in this report, we describe a rare facial nerve neuroma in the mastoid portion in a 55-year-old man with a history of hypertension (htn) and diabetes mellitus (...

to access the surgical progress of patients with long segment aganglionosis and long-term evaluation. during the past 15 years, we reviewed the therapy and outcome of 15 patients with long-segment agangelionosis (lsa) in mofid children's hospital. 2 with agangelionosis to the midtransvers colon (mta(, 8 to the ascendant and cecum (a/ca), 4 with total colonic and distal ileum involvement (tca), ...

background epstein barr virus (ebv) is one of the most common viral infections in human population. ebv has a significant role in pathogenesis of hodgkin's lymphoma, burkitt's lymphoma and nasopharyngeal carcinoma. the role of ebv in non-hodgkin’s lymphoma, diffuse large b cell (nhl - dlbl) in the head and neck is controversial. objectives the purpose of this study is to find out the ...

Individual tree crown segmentation from Airborne Laser Scanning data is a nodal problem in forest remote sensing. Focusing on single layered spruce and fir dominated coniferous forests, this article addresses the problem of directly estimating 3D segment shape uncertainty (i.e., without field/reference surveys), using a probabilistic approach. First, a coarse segmentation (marker controlled wat...

With the increase in current densities, electromigration has become a critical concern in high-performance designs. Typically, electromigration has involved the process of time-domain simulation of drivers and interconnect to obtain average, root mean square (rms), and peak current values for each wire segment. However, this approach cannot be applied to large problem sizes where hundreds of th...

background: while myoma is the most common pelvic mass of women, most women do not seek screening tests for uterine myoma and if they have any fibroid they are not volunteer for its surgical removal. case: we present here a novel technique of vascular skeletonization to preserve uterus, making pregnancy possible for an infertile woman with a large uterine myoma, situated in the uterine lower se...

Introduction: Developmental changes in atrioventricular nodal conduction time and refractoriness have been shown in several studies. Prevalence of atrioventricular nodal reentrant tachycardia (AVNRT) is clearly age-dependent. The purpose of this study was to determine developmental changes of basic and frequency-dependent electrophysiological properties of the atrioventricular node (AV-node)...
