فرض کنید g یک گروه متناهی باشد به طوری که مربع هر درجه کاراکتر تحویل ناپذیر آن اندیس مرکز گروه را عاد می کند. آیا می توان نتیجه گرفت که گروه پوچتوان یا حتی حلپذیر است؟ همچنین در مورد بعضی از تعمیمهای فوقالذکر بحث خواهیم کرد. همچنین، تا چه اندازه ساختار یک گروه حلپذیر توسط بزرگترین درجه کاراکتر تحویل ناپذیر گروه تحت تاثیر قرار میگیرد مورد بحث قرار خواهد گرفت. let g be a finite group such tha...
Cyclooxygenase-2 (COX-2) catalyzes the rate-limiting step in the prostanoid biosynthesis pathway, converting arachidonic acid into prostaglandin H(2). COX-2 exists as 72 and 74kDa glycoforms, the latter resulting from an additional oligosaccharide chain at residue Asn(580). In this study, Asn(580) was mutated to determine the biological significance of this variable glycosylation. COS-1 cells t...
A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator. Using 91 deceleration solenoids, the atoms were decelerated from an initial velocity of 580 m/s to final velocities as low as 105 m/s, corresponding to a removal of more than 95...
A smooth approximation p(x;) to the plus function: maxfx; 0g, is obtained by integrating the sigmoid function 1=(1 + e ?x), commonly used in neural networks. By means of this approximation, linear and convex inequalities are converted into smooth, convex unconstrained minimization problems, the solution of which approximates the solution of the original problem to a high degree of accuracy for ...
Low-density compressible materials enable various applications but are often hindered by structure-derived fatigue failure, weak elasticity with slow recovery speed and large energy dissipation. Here we demonstrate a carbon material with microstructure-derived super-elasticity and high fatigue resistance achieved by designing a hierarchical lamellar architecture composed of thousands of microsc...

The purpose of this work is to investigate the relation of hydration and the degree of crystallinity for poly (ethylene oxide) (PEO) tablets using Raman spectroscopic methods and complementary thermal analysis for pharmaceutical interests. The influence of the tableting process is also investigated by measuring the degree of crystallinity and the melting point of PEO powder and tablets. The hyd...
The study was conducted to evaluate the degree of calcification in the jawbones of 3 pairs of 4-week-old male op/op mice and littermates using computed tomography (CT) numbers. The mean CT numbers for op/op mice (n = 3) were 251.3 HU (range, 226 to 278) in the maxillary bone and 353.7 HU (range, 320 to 398) in the mandibular bone. The mean CT numbers for littermates were 336.7 HU (range, 324 to...
The functional properties of the light adaptation system in the superposition eye of the moth Agrotis segetum have been investigated by reflection spectroscopy. The spectrum of the reflected light from the tapetum of dark adapted eyes had a peak at about 580 nm corresponding to a spacing between the reflecting layers in the tapetum of 145 nm. During light adaptation of the eye the observed refl...
