The author investigates Russian federalism and the constitutional underpinnings of the power vertical, looking specifically at the Constitutional Court’s December 2005 case about the appointment of governors. The court’s decision upheld the constitutional notion of a “unified system of executive power” as the primary legal justification for the power vertical. However, not all of the justices a...

A machine-generated list of 192 local solutions of the Heun equation is given. They are analogous to Kummer’s 24 solutions of the Gauss hypergeometric equation, since the two equations are canonical Fuchsian differential equations on the Riemann sphere with four and three singular points, respectively. Tabulation is facilitated by the identification of the automorphism group of the equation wit...

The data on the prevalence of potentially inappropriate medications (PIMs) use and their predictors among elderly systemic autoimmune disorders is still unknown. Hence, we aimed to determine medication (PIM) patients with disorders. Patients who were admitted or visited department rheumatology in a tertiary care teaching hospital between July 2019 April 2021 included this study. any gender, age...

Rad51 is a key enzyme involved in DNA double-strand break repair by homologous recombination. Here, we show that in response to DNA damage, budding yeast Rad51 is phosphorylated on Ser 192 in a manner that is primarily mediated by the DNA-damage-responsive protein kinase Mec1. We show that mutating Rad51 Ser 192 to Ala or Glu confers hypersensitivity to DNA damage and homologous-recombination d...

Hash functions are the most widespread among all cryptographic primitives, and are currently used in multiple cryptographic schemes and in security protocols. This paper presents a new Secure Hash Algorithm called (SHA-192). It uses a famous secure hash algorithm given by the National Institute of Standard and Technology (NIST).The basic design of SHA192 is to have the output length of 192.The ...

BACKGROUND Although several early trials indicate treatment of restenosis with radiation therapy is safe and effective, the long-term impact of this new technology has been questioned. The objective of this report is to document angiographic and clinical outcome 3 years after treatment of restenotic stented coronary arteries with catheter-based (192)Ir. METHODS AND RESULTS A double-blind, ran...

در این مقاله، هدف طراحی و ساخت سامانه تشخیصی پروب لانگمویر جهت اندازه ­گیری پارامترهای پلاسما دستگاه گداخت به ­روش محصورسازی الکترواستاتیکی اینرسی ایران (IR-IECF) به­ منظور مشخصه­ یابی چشمه‌­ی پلاسمایی می‌­باشد. بدین‌­منظور، یک برای اندازه‌­گیری مختلف از جمله دمای الکترون­، چگالی الکترون، یون، پتانسیل ساخته شده است. با نظر گرفتن مشخصات چشمه IR-IECF، الکترود مورد استفاده مفتول جنس تنگستن قطر طول...

ادغام داده‌ها بین حسگرهای مختلف می‌تواند موجب استخراج اطلاعات با دقت و کیفیت بالاتر گردد بهبود تشخیص تهدیدهای هسته‌ای را به همراه داشته باشد. در این تحقیق، ردیابی چشمه متحرک استفاده از تلفیق داده­های سیستم آشکارساز پرتوی دوربین نظارتی مورد مطالعه قرار گرفت است. بدین منظور الگوریتمی جهت ایجاد همبستگی تصاویر دریافتی توسط شمارش طراحی شده است تا مسیر حرکت جسمی که بیش­ترین ثبت آشکارسازی دارد عنوان ا...

Source positioning close to the tumour in high dose rate (HDR) brachytherapy is not instantaneous. An increment of dose will be delivered during the movement of the source in the trajectory to its static position. This increment is the transit dose, often not taken into account in brachytherapeutic treatment planning. The transit dose depends on the prescribed dose, number of treatment fraction...
