در تحلیل بقا بدست آوردن توزیع پارامتری زمان بقا از اهمیت ویژه ای برخوردار است، به طوری که می توان احتمال بقا و احتمال خطر را در تمام زمان ها به طور دقیق محاسبه نمود، در حالتی که برای تابع بقا تحت مطالعه بتوان توزیع پارامتری معقولی را در نظر گرفت مسا له برآورد نسبتا آسان می باشد و عموما برآوردها بر اساس نگرش حداکثر درستنمایی برآورد می شوند. اما اگر به هر دلیلی از جمله مکانیسم سانسور شدن نتوان مد...
Introduction: The current study investigated the combination of high Z atoms (iodine-, platinium-based drugs) with using low energy irradiation (120kvp) in Anaplastic Thyroid cancer cells.Materials and Methods: For this purpose, eight groups were designed: control (CNT), different concentrations of Iodine contrast media (ICM), irradiation with various doses, Cis-platin (CDDP) with different c...
ICM0201 (1), a new inhibitor of murine osteoclastogenesis in culture was isolated from a fermentation broth of Cunninghamella sp. F-1490. The structure of ICM0201 was determined to be (3S,10aR)-3,4a-dihydroxy-2,3,4,4a-tetrahydro-2H-pyrano[3,2-b]benzo[e]morpholine-9-carboxylic acid by spectroscopic analyses and chemical studies. The structure of 1 is unique in that the tricycle ring system is co...
Introduction: One of the most important changes in medical education programs in Iran has been designing and implementing course of Introduction to Clinical Medicine (ICM) in Isfahan University of Medical Sciences. This study determines the methods and results of process evaluation (from CIPP evaluation) used for ICM revision and evaluation program. This study aimed to provide evidences about i...
In large open pit mines prediction of Peak Particle Velocity (PPV) provides useful information for safe blasting. At Sungun Copper Mine (SCM), some unstable rock slopes facing to valuable industrial facilities are both expose to high intensity daily blasting vibrations, threatening their safty. So, controlling PPV by developing accurate predictors is essential. Hence, this study proposes improv...
Nowadays, interval comparison matrices (ICM) take an important role in decision making under uncertainty. So it seems that a brief review on solution methods used in ICM should be useful. In this paper, the common methods are divided into four categories that are Goal Programming Method (GPM), Linear Programming Method (LPM), Non-Linear Programming Method (NLPM) and Statistic Analysis (SA). GPM...
در این پایان نامه به بخش بندی تصاویر چندطیفی پرداخته می شود. برای این منظور روش جدیدی با عنوان مدل بر پایه مدل درختی معرفی می شود. این روش بر پایه خوشه بندی با استفاده از مدل های آمیخته متناهی و براورد پارامترها با استفاده از بیشینه کردن تابع درستنمایی و حل آن با الگوریتم em می باشد. تعیین تعداد خوشه ها بوسیله معیار انتخاب بیز که توسط bic تخمین زده می شود معیین می گردد. وابستگی مکانی پیکسل ه...
Ischemic cardiomyopathy (ICM) is an important cause of heart failure, yet no ICM disease genes were stored in any public databases. Mutations of genes provided by RNA-Seq data could set a foundation for a variety of biological processes. This also made it possible to elucidate the mechanism and identify potential genes for ICM. In this paper, an integrated co-expression network was constructed ...
Objective This study assessed the risk of acute allergic-like reactions (AARs) after extravascular administration of iodinated contrast media (ICM) in at-risk patients compared with that after intravascular ICM administration. Materials and Methods From July 2012 to January 2016, 264 patients with a history of moderate or severe reactions to ICM, with re-exposure to ICM intravascularly or ext...
