we describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. we present a new method for computing, electronic transport wave function and greens function of the disordered graphene. in this method, based on the small rectangular approximation, break up the potential barriers in to small parts. then using the f...
در سالیان اخیر توجه زیادی روی موضوع تشخیص خطا در واحدهای مختلف شیمیائی بوسیله روشهای مختلف شده است . که یکی از این روشها شبکه های عصبی می باشد که شامل سه مرحله، آموزش ، بازخوانی و عمومیت بخشیدن می باشد. در این مقاله با استفاده از شبکه های عصبی مصنوعی (network artificial neural) از نوع (rbf)radial basis function و (bp) backpropagation خطاهای ایجاد شده در برج تقطیر تشخیص داده می شود. جهت آموزش اب...
The Particle Data Group decided to split the η(1440) into two states, called ηL and ηH . The η(1295) and the ηH are supposed to be the radial excitations of the η and η, respectively. The ηL state cannot be accomodated in a quark model; it cannot be a qq̄ state, however, it might be a glueball. In this contribution it is shown that that the η(1295) does not have the properties which must be expe...

Radial Extracorporeal Shock Wave Therapy in a Person With Advanced Osteonecrosis of the Femoral Head
This case report describes the first patient with avascular necrosis of the femoral head of Association Research Circulation Osseous stage IV, treated with radial extracorporeal shock wave therapy. By contrast, previous studies demonstrated the efficacy of a single treatment of focused extracorporeal shock wave therapy in improving pain and Harris Hip Scale in patients with avascular necrosis o...
Radial basis functions (RBFs) are a powerful tool for approximating the solution of high-dimensional problems. They are often referred to as a meshfree method and can be spectrally accurate. In this paper, we analyze a new stable method for evaluating Gaussian radial basis function interpolants based on the eigenfunction expansion. We develop our approach in two-dimensional spaces for so...
Introduction:The commercial 252Cf sources are too large in size and clinical applications of neutronbrachytherapy (NBT) are limited to a small number of intracavitary treatments of cervical cancers. Recently, under the Cooperative Research and Development Agreement (CRADA) with Isotron Inc., the Oak Ridge National Laboratory (ORNL) encapsulated a new medical 252Cf sources, cal...
In this paper, the Schrodinger equation for a quantum wire is solved using a finite difference approach. A new aspect in this work is plotting wave function on cross section of rectangular cross-sectional wire in two dimensions, periodically. It is found that the correct eigen energies occur when wave functions have a complete symmetry. If the value of eigen energy has a small increase or decr...
BACKGROUND It remains incompletely understood whether patients with transfusion related cardiac iron overload without signs of heart failure exhibit already subclinical alterations of systolic left ventricular (LV) dysfunction. Therefore we performed a comprehensive evaluation of systolic and diastolic cardiac function in such patients using tagged and phase-contrast CMR. METHODS 19 patients ...
We study radial wave packets produced by short-pulsed laser fields acting on Rydberg atoms, using analytical tools from supersymmetrybased quantum-defect theory. We begin with a time-dependent perturbative calculation for alkali-metal atoms, incorporating the atomicexcitation process. This provides insight into the general wave packet behavior and demonstrates agreement with conventional theory...
