عملکرد یک نمودار x-bar معمولاً تحت این فرض که انحراف معیار فرآیند به خوبی تخمین زده شده و تغییر نمی کند، بررسی می شود. البته این فرض در عمل معمولاً درست نبوده و نمودارهای x-bar در برابر اشتباهات تخمین انحراف معیار فرآیند یا تغییرات انحراف معیار پایدار نیستند. در این تحقیق، به بررسی یک نمودار کنترل میانگین متحرک موزون نمایی با بازه های نمونه گیری متغیر برای کنترل تغییرات در میانگین فرآیند پرداخته ...
The extended Fes-CIP4 homology (EFC)/FCH-BAR (F-BAR) domain tubulates membranes. Overexpression of the pacsin2 EFC/F-BAR domain resulted in tubular localization inside cells and deformed liposomes into tubules in vitro. We found that overexpression of the pacsin2 EFC/F-BAR domain induced cellular microspikes, with the pacsin2 EFC/F-BAR domain concentrated at the neck. The hydrophobic loops and ...
A bar visibility representation of a graph G is a collection of horizontal bars in the plane corresponding to the vertices of G such that two vertices are adjacent if and only if the corresponding bars can be joined by an unobstructed vertical line segment. In a bar k-visibility graph, two vertices are adjacent if and only if the corresponding bars can be joined by a vertical line segment that ...
The BAR (Bin-Amphiphysin-Rvs) domain undergoes dimerization to produce a curved protein structure, which superimposes onto membrane through electrostatic interactions to sense and impart membrane curvature. In some cases, a BAR domain also possesses an amphipathic helix that inserts into the membrane to induce curvature. ACAP1 (Arfgap with Coil coil, Ankyrin repeat, and PH domain protein 1) con...

Isolated barred galaxies evolve by redistributing their internal angular momentum, which is emitted mainly at the inner disc resonances and absorbed mainly at the resonances in the outer disc and the halo. This causes the bar to grow stronger and its pattern speed to decrease with time. A massive, responsive halo enhances this process. I show correlations and trends between the angular momentum...
The purpose of this study was to examine the influence of two different bar diameters on neuromuscular activation and strength. The bar diameters used reflected a standard Olympic bar (28 mm (1.1 inch); THIN) and a larger fat bar (51 mm [2 inch]; THICK). Eighteen healthy men (age 25.06 1 years) were assessed for their maximal voluntary contraction (MVC) during a unilateral isometric bench press...
For decades, the grand-design SAB spiral galaxy NGC 5248 has been postulated to host a short bar of semimajor axis 22 (1.6 kpc). From dynamical and morphological arguments, however, we argue that its spiral structure is being driven by a large-scale bar whose corotation radius lies at ∼115 (8.6 kpc). Our estimate is based partially on a deep R-band image, which reveals that the feature previous...
مقدمه: به علت مشکلات دنچرها، امروزه اوردنچرهای متکی بر ایمپلنت رواج یافتهاند. به رغم موفقیت بالای ایمپلنت، از دست رفتن ایمپلنت هنوز معضل اساسی است. افزایش نیروی وارد بر ایمپلنت فاکتور مهم تحلیل استخوان و از دست رفتن ایمپلنت میباشد. این مطالعه با آنالیز اجزای محدود اوردنچرهایی با سه ایمپلنت، به بررسی بهترین طراحی و ترکیب اتچمنت که باعث حداقل استرس در استخوان آلوئول شود، پرداخته است. مواد و روش...
The interaction between cosmic rays and the gravitational wave bar detector NAUTILUS is experimentally studied with the aluminum bar at temperature of T=1.5 K. The results are compared with those obtained in the previous runs when the bar was at T=0.14 K. The results of the run at T = 1.5 K are in agreement with the thermo-acoustic model; no large signals at unexpected rate are noticed, unlike ...
