In this paper, a new definition of numerical radius for adjointable operators in Hilbert -module space will be introduced. We also give a new proof of numerical radius inequalities for Hilbert space operators.

The determination of gyration radius is a strong research for configuration of a Macromolecule. Italso reflects molecular compactness shape. In this work, to characterize the behavior of theprotein, we observe quantities such as the radius of gyration and the average energy. We studiedthe changes of these factors as a function of temperature for Acetylcholine receptor protein in gasphase with n...

In recent years, relativistic matter waves have been applied to the solar system explain some quantum gravity effects. This paper shows that size and Earth’s are consequences of Bode’s rule in terms wave. The radius is determined as 7e+8 (m) with a relative error 0.72%; 6.4328e+6 0.86%. atmospheric circulation also investigated wave, wind fields on surface calculated, results agree well experim...

introduction: restoration of normal anatomic alignment is a key component of the treatment of distal radius fractures (drf). this study aimed to evaluate the accuracy of ultrasonography (us) in determining the adequacy of closed reduction in these fractures. methods : drf patients admitted to the emergency department of al-zahra hospital, isfahan, iran from september 2011 to 2012, were enrolled...

در آشکار‌ساز CMS نسبت‌های انشعاب بوزون هیگز مدل استاندارد به جفت‌‌های J/ψ(1S) و cc ترتیب برابر 2-10×1/8 2-10×2/89 اندازه‌گیری شده است. لحاظ نظری یکی از سناریوهای ممکن برای تولید مستقیم این است که آغاز جفت واپاشی نماید سپس مرحله‌ی بعد هر یک کوارک‌های c طور مزون ترکش کنند. بر اساس سناریو مقاله بطریق کوارک‎های با استفاده نظریه اختلال مکانیک کوانتومی رنگ (pQCD) نظر گرفتن حالت‌های قطبش طولی عرضی محا...

In this paper, an attempt is made for solution of free vibration analysis of annular plate reinforced with carbon nanotubes for Uniformly Distribution (UD), resting on an elastic foundation using a refined theory presented. In this theory, a parabolic distribution of shear stress and strain in the thickness direction and satisfies the boundary conditions of zero shear stress on the upper and lo...

Background: Osteoporosis is a common condition among the elderly population, and is associated with an increased risk of fracture. One of the most common fragility fractures involve the distal radius, and are associated with risk of subsequent fragility fracture. Early treatment with bisphosphonates has been suggested to decrease the population hip fracture burden. However, there have been no p...
