We propose a generalized regression neural network (GRNN) approach based on grey relational analysis (GRA) and principal component analysis (PCA) (GP-GRNN) to improve the accuracy of density functional theory (DFT) calculation for homolysis bond dissociation energies (BDE) of Y-NO bond. As a demonstration, this combined quantum chemistry calculation with the GP-GRNN approach has been applied to...
Glucocorticoid-remediable aldosteronism (GRA) is an autosomal-dominant inheritable form of hyperaldosteronism with early onset hypertension. GRA is caused by unequal crossing-over of the steroid 11 beta-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2) genes. As a result of chimeric gene duplication, aldosterone is ectopically synthesized in the adrenal zona fasciculata under the control...
Activated CTLs and NK cells induce apoptosis via multiple mechanisms, including that termed granule exocytosis. The latter pathway consists of vectorial secretion of perforin and a family of granule-associated serine proteases (granzymes) to the target cell. To establish whether granzymes are released extracellularly during cytolytic reactions in vivo, ELISAs that measure the native enzymes wer...
INTRODUCTION Sulforaphane (SFN) is an isothiocyanate derived from glucoraphanin (GRA), which is found in great amounts especially in broccoli. Its consumption has been reported to be associated with a lower risk of myocardial infarction and cancer development. Additionally, its effects have been studied in neurodegenerative diseases, diabetes, and atherosclerosis, most of the times using animal...
With the advent of technology and introduction computational intelligent methods, prediction slope failure using machine learning (ML) approach is rapidly growing for past few decades. This study employs an “artificial neural network” (ANN) to predict failures based on historical circular cases. Using feed-forward back-propagation algorithm with a multilayer perceptron network, ANN powerful ML ...
چکیده- صفحات مستغرق، سازههایی هستند که در بستر رودخانهها و کانالها با زاویهای در برابر جریان نصب می شوند. این سازهها معمولاً به صورت گروهی استفاده میشوند و کارکرد اصلی آن ها ایجاد جریان گردابی و تغییر الگوی جریان و بستر است. کارکرد صفحات مستغرق تحت تأثیر شاخص های هندسی آن ها است. در این پژوهش، شاخص های هندسی یک صفحه مستغرق در بستر رسوبی کانال مستقیم با مدل سازی عددی بهینه سازی شده است. منظ...
Herein, we have investigated the adsorption behavior of gas molecules, including C2H2, H2S, SO2, SO3, and O2, on FeN3-doped graphene (FeN3-gra). The change geometric stability, electric structure, magnetic properties is discussed comprehensively. results demonstrated that stability substrate enhanced by hybridization between Fe N atoms in FeN3-gra. Besides, dopant can enhance ability gases grap...
Single valued neutrosophic hesitant fuzzy set has three independent parts, namely the truth membership hesitancy function, indeterminacy membership hesitancy function, and falsity membership hesitancy function, which are in the form of sets that assume values in the unit interval [0, 1]. Single valued neutrosophic hesitant fuzzy set is considered as a powerful tool to express uncertain, incompl...

BACKGROUND Adequate bowel preparation is an essential prerequisite for complete mucosal visualization during colonoscopy. Polyethylene glycol (PEG) solutions are commonly used. However the large volume of the solution is often poorly tolerated. Addition of Lubiprostone (LB) could improve the adequacy of standard PEG preparation & reduce requirement. The aims to assess adequacy of PEG preparatio...
