در این پایان نامه، به اثبات قضیه های پایداری اولام- هایرز تعمیم یافته با استفاده از روش مستقیم وروش نقطه ثابت می پردازیم. 2f(x + y/2 )+ f(x - y/2 )+ f(y - x/2 )= f(x) + f(y): همچنین به مطالعه پایداری اولام - هایرز تعمیم یافته همریختی های تصادفی در جبر های نرم دارتصادفی می پردازیم
BACKGROUND Goiter rates and iodine deficiency usually show marked improvement in efficacy studies of mandatory iodization of salt, but little is known about the short-term effectiveness of mandatory iodization. OBJECTIVE The aim of the study was to evaluate, after 1 y, the effectiveness of mandatory iodization of salt at an iodine concentration higher than that occurring under optional iodiza...
Yttrium-90 Radioembolization for Colorectal Cancer Liver Metastases: A Single Institution Experience
Purpose. We sought to evaluate our experience using yttrium-90 ((90)Y) resin microsphere hepatic radioembolization as salvage therapy for liver-dominant metastatic colorectal cancer (mCRC). Methods. A retrospective review of consecutive patients with unresectable mCRC who were treated with (90)Y after failing first and second line systemic chemotherapy. Demographics, treatment dose, biochemical...
This study aimed to test the hypothesis that root morphology might be improved and consequently contributing to superior post-heading shoot growth and grain yield in late-stage vigor super rice. A pot experiment was carried out to compare yield attributes, shoot growth and physiological properties and root morphological traits between a late-stage vigor super rice cultivar (Y-liangyou 087) and ...
Angiotensin II (Ang II) acts mainly on two receptor subtypes: AT1 and AT2. Most of the known biological actions of Ang II are mediated by AT1 receptors; however, the role of AT2 receptors remains unclear. We tested the hypothesis that the cardioprotective effects of AT1 receptor antagonists (AT1-ant) after myocardial infarction (MI) are partially mediated by activation of AT2 receptors; thus in...
The Maximum Entropy Modeling Toolkit supports parameter estimation and prediction for statistical language models in the maximum entropy framework. The maximum entropy framework provides a constructive method for obtaining the unique conditional distribution p*(y|x) that satisfies a set of linear constraints and maximizes the conditional entropy H(p|f) with respect to the empirical distribution...
in this paper, we introduce the notion of derivation on krasner hyperrings as follows: the function d : r r isa derivation on a krasner hyperring r if for all , , ry x ) ( ) ( = ) ( y d x d y x d andd (x y) d (x) y x d ( y). then, we investigate some fundamental properties of derivation on krasnerhyperings and prime krasner hyperrings. also, we introduce differential krasner hy...
در این پایاننامه روشهای ماتریسی حافظ ساختار خطی [ 15 ] و غیرخطی [ 1] برای s(f, g) از ماتریس برآیند سیلوستر s(f?, g?) محاسبهی تقریب رتبهپایین ساختاریافته f?(x) بررسی شده است، که در آن g = g(y) و f = f(y) از دو چندجملهای غیردقیق به شرح زیر میباشند: g?(x) و ? f(x) = ?m i=0 (ai + ?ai)xi , ?g(x) = ?n i=0 (bi + ?bi)xi (1) پردازش g(y) و f(y) چندجملهایهای s(f?, g?) نشان داده شده که اگر قبل ا...
