Introduction: The conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. Although the polymer gel dosimetry method based on magnetic resonance imaging (MRI) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...

Road extraction using remote sensing images has been one of the most interesting topics for researchers in recent years. Recently, the development of deep neural networks (DNNs) in the field of semantic segmentation has become one of the important methods of Road extraction. In the Meanwhile The majority of research in the field of road extraction using DNN in urban and non-urban areas has been...
purpose of this study is analysis of spatial auto-correlation of freezing changes of iran over the last half century. daily temperature data over the period 1340 - 1383 of esfezari database provided by doctor masoodian (to enhance the temporal resolution of the database, daily observations of temperature from 1383 to the end of 1390 using the same method and the same spatial resolution is added...
Research of perceptual learning has received significant interest due to findings that training on perceptual tasks can yield learning effects that are specific to the stimulus features of that task. However, recent studies have demonstrated that while training a single stimulus at a single location can yield a high-degree of stimulus specificity, training multiple features, or at multiple loca...
introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...
سابقه و هدف: آنالیز hrm (high resolution melting) تکنیکی است که میزان کاهش فلورسنت را در طی فرایند شیب حرارتی ذوب dna در اثر خروج رنگ اندازه گیری می نماید. ژن stk11 یکی از پروتئین های خانواده سرین- ترئونین کیناز سلولی را رمز می نماید که تنظیم کننده قطبیت سلولی بوده و هم چنین به عنوان پروتئین مهار کننده تومور عمل می نماید. موتاسیون های ژرم لاین در این ژن همراه با سندروم peutz-jeghers واستعداد اب...
