BACKGROUND AND PURPOSE To evaluate the mechanisms of failure of blood oxygenation level-dependent (BOLD) imaging in stroke, we compared the evoked cerebral blood oxygenation (CBO) responses and activation volumes (AVs) of BOLD functional MRI (fMRI) in chronic stroke patients with moderate and severe cerebral ischemia. METHODS We measured the evoked CBO responses in the primary sensorimotor co...
امروزه قیمت نفت نقش مهمی را در اقتصاد جهانی ایفا می‌کند و به عنوان یک عامل مهم و اثرگذار بر برنامه‌های دولت‌ها و بخش‌های تجاری و بازرگانی اهمیت فراوانی دارد. با توجه به اهمیت روز افزون نفت در بازارهای مالی، پیش‌بینی قیمت نفت خام همواره مورد علاقه بسیاری از فعالان بازار و سیاستگذاران بوده است. در این راستا، در این پژوهش، ضمن بررسی و انجام آزمون غیرخطی برای داده‌های ماهانه قیمت نفت خام، به مدل‌س...
در این پایاننامه الگوریتمهای برنامهریزی پویا برای حل مسالهی بهینهسازی حداقل تصحیح خطا بهعنوان شاخهای از مسالهی برهمگذاری هاپلوتایپ مورد بررسی قرار میگیرند. سپس به مقایسهی چنین الگوریتمهایی در دو حالت بدون وزن و وزندار مسالهی حداقل تصحیح خطا پرداخته میشود. نتایج بررسیهای نظری برتری الگوریتم برنامهریزی پویا را به ازای حالت وزندار این مساله نشان میدهد. از آنجایی که الگوریتم وزندار امکان بررسی ...
In this paper, we propose a predictor-corrector type Consensus Based Optimization(CBO) algorithm on convex feasible set. Our proposed generalizes the CBO in [11] to tackle constrained optimization problem for global minima of non-convex function defined domain. As practical application algorithm, study portfolio finance. application, introduce an objective choose optimal weight each asset asset...
Blood-oxygen-level-dependent contrast functional magnetic resonance imaging (BOLD-fMRI) has been used to perform functional imaging in brain disorders such as stroke and brain tumors. However, recent studies have revealed that BOLD-fMRI does not image activation areas correctly in such patients. To clarify the characteristics of the evoked cerebral blood oxygenation (CBO) changes occurring in s...
OBJECTIVES To explore models to improve HIV testing, linkage to care and treatment among men who have sex with men (MSM) in cooperation with community-based organizations (CBOs) in China. METHODS We introduced a new model for HIV testing services targeting MSM in six cities in 2013.These models introduced provision of rapid HIV testing by CBO staff and streamlined processes for HIV screening,...
The paper presents a survey of recent advances in algorithms for computing all formal concepts in a given formal context which result as modifications or extensions of CbO. First, we present an extension of CbO, so called FCbO, and an improved canonicity test that significantly reduces the number of formal concepts which are computed multiple times. Second, we outline a parallel version of the ...
A common business object is an object which is used often by web-based applications and services and is a widely acceptable entity in the running of the business. For example, a purchase order (PO), an invoice, and a customer profile could be considered common business objects, as these are parts of day-to-day business activity, but more importantly these have well-established and commonly acce...
BACKGROUND Studies of implementation of efficacious human immunodeficiency virus (HIV) prevention interventions are rare, especially in resource-poor settings, but important, because they have the potential to increase the impact of interventions by improving uptake and sustainability. Few studies have focused on provider and organizational factors that may influence uptake and fidelity to core...
