مدلهای گارچ در فضاهای هیلبرت پایان نامه حاضر شامل دو بخش می باشد. در قسمت اول مدلهای اتورگرسیو تعمیم یافته مشروط به ناهمگنی واریانس در فضاهای هیلبرت را معرفی، مفاهیم ریاضی مورد نیاز در تحلیل این مدلها در دامنه زمان را مطرح کرده و آنها را مورد بررسی قرار می دهیم. بر اساس پیشرفتهایی که اخیرا در زمینه تئوری داده های تابعی و آماره های عملگری ایجاد شده است، فرآیندهایی که دارای مقادیر در فضاهای ...
For decades, the Earth Science (ES) community has launched missions to monitor vital phenomena of our planet and, through measurements, obtain data for improving their models. Indeed the proper characterisation of phenomena, such as desertification, Arctic sea ice melting, volcanic activities or earthquakes effects, requires the analysis of data acquired in a long period and the validation of c...
Eukaryotic translation initiation factor 2, subunit 3, and structural gene Y-linked (EIF2S3Y) is essential for spermatogenesis in mouse models. However, its effect on embryonic stem (ES) cells remains unknown. In our observation, differentiated ES cells showed higher levels of EIF2S3Y. To further elucidate its role in ES cells, we utilized ES-derived EIF2S3Y-overexpressing cells and found that ...
BACKGROUND This study used receiver operating characteristic curve to analyze Surveillance, Epidemiology and End RESULTS (SEER) Ewing sarcoma (ES) outcome data. The aim of this study was to identify and optimize ES-specific survival prediction models and sources of survival disparities. MATERIALS AND METHODS This study analyzed socio-economic, staging and treatment factors available in the SE...
Expected Shortfall (ES) is the average return on a risky asset conditional on the return being below some quantile of its distribution, namely its Value-at-Risk (VaR). The Basel III Accord, which will be implemented in the years leading up to 2019, places new attention on ES, but unlike VaR, there is little existing work on modeling ES. We use recent results from statistical decision theory to ...
BACKGROUND AND AIM: This study was performed to evaluate and compare the calcification patterns of the stylohyoid ligament in Eagle’s syndrome (ES) patients, and asymptomatic patients with elongated styloid process (SP) via cone-beam computed tomography (CBCT).METHODS: A total of 52 CBCT images in two symptomatic (ES) and asymptomatic groups (n = 26 per group) were assessed. The mean length an...
An integrated approach to understanding the linkages between ecosystem services and human well-being
In order to use science to manage human–nature interactions, we need much more nuanced, and when possible, quantitative, analyses of the interplay among ecosystem services (ES), human well-being (HWB), and drivers of both ecosystem structure and function, as well as HWB. Despite a growing interest and extensive efforts in ES research in the past decade, systematic and quantitative work on the l...
"The child is father of the man" is the philosophy of the paediatrician, hence the recent trend of intense interest in child development, which embraces the study of factors which influence the growth of the body, mind, personality and spirit from conception to maturity and ultimate achievement. As practitioners of medicine it is natural that much of our effort should be used in the diagnosis a...
مقدمه و اهداف مطالعه حاضر به منظور بررسی تکرارپذیری درون آزمونگر نرمافزار همزمانسازی(Synchronization) در بررسی همزمان عضله تیبیالیس انتریور از نظر پارامترهای سونوگرافی و دینامومتری در حین انقباض در افراد سالم غیرورزشکار انجام شد. این نرمافزار به منظور افزایش توانایی در ثبت همزمان تصاویر اولتراسونوگرافی و دادههای دینامومتر استفاده شد. مواد و روشها در مطالعه حاضر تکرارپذیری پارامترهای ساختار...
The market for enterprise systems (ES), continues to grow in the post millennium era as businesses become increasingly global, highly competitive, and severely challenged. Although the large enterprise space for ES implementation is quite stagnated, now all of the ES vendors are focusing on the small to medium-sized enterprise (SME) sector for implementations. This study looks at the current ES...
