Let A = { a 1 , … m } ? N be measurable functions on space ( X ) . If ? is positive measure such that ? i d < ? for all then the sequence called truncated moment sequence. By Richter's Theorem each has k -atomic representing with ? The set S of sequences cone. aim this paper to analyze various structures main results concern facial structure (exposed faces, dimensions) and lower upper bounds Ca...
Numerical simulations of hydrated proteins show that protein hydration shells are polarized into a ferroelectric layer with large values of the average dipole moment magnitude and the dipole moment variance. The emergence of the new polarized mesophase dramatically alters the statistics of electrostatic fluctuations at the protein-water interface. The linear response relation between the averag...
We consider the best entropic estimation to a unknown density x, given some of its algebraic or trigonometric moments. A uniform convergence theorem is established in this paper for such problems using Fermi-Dirac type entropic objectives .
این تحقیق به بررسی سطح فرسودگی وتحلیل رفتگی شغلی و عوامل احتمالی آن درمیان معلمان زبان انگلیسی که در موسسات زبان انگلیسی ارومیه مشغول به کار هستند پرداخته است. برای این منظور، یک گروه 140 نفری از معلمان زبان انگلیسی مرد وزن بطور تصادفی از موسسات زبان انتخاب شدند. پرسشنامه ای جهت جمع آوری اطلاعات شخصی از جمله سن، جنسیت وسابقه تدریس در میان شرکت کننده ها توزیع شد. پرسشنامه دیگری تحت عنوان پرسشنام...
enzymes catalyze many biological reactions. the rates of chemical reaction in the presence ofenzymes are, in some cases, accelerated more than 10 orders of magnitude relative to thecorresponding rates in solution.in this paper a comparison between optimized structures of two enzyme molecules in aspect ofenergy and dipole moment in different conditions including presence of metallic ion, without...
Stochastic fluctuations of coherent and incoherent components of the resonance fluorescence intensity induced by Wiener-Levy laser phase noise are investigated. Statistical properties of the atomic dipole moment and stochastic Mollow spectra of atomic dipole fluctuations for different values of the laser linewidth and Rabi frequency are calculated. It is shown that these spectra exhibit a tripl...
We present the first results of a new search for a permanent electric dipole moment of the 199Hg atom using a UV laser. Our measurements give d(199Hg) = -(1.06+/-0.49+/-0.40)x10(-28)e cm. We interpret the result as an upper limit absolute value [d(199Hg)]<2.1x10(-28)e cm (95% C.L.), which sets new constraints on theta bar;(QCD), chromo-EDMs of the quarks, and CP violation in supersymmetric models.
The energy flow lines (field lines of the Poynting vector) for radiation emitted by a dipole are in general curves, rather than straight lines. For a linear dipole the field lines are straight, but when the dipole moment of a source rotates, the field lines wind numerous times around an axis, which is perpendicular to the plane of rotation, before asymptotically approaching a straight line. We ...
