This paper proposes an improved score function for the effective ranking order of interval-valued intuitionistic fuzzy sets (IVIFSs) and an interval-valued intuitionistic fuzzy TOPSIS method based on the score function to solve multicriteria decision-making problems in which all the preference information provided by decision-makers is expressed as interval-valued intuitionistic fuzzy decision ...
سابقه هدف: msیکی از شایعترین اختلالات نورولوژیک ناتوان کننده است که با تریاد التهاب ، demyelination ، وگلیوزیس نورونها مشخص می شود . بیش از 2.5 میلیون نفر در جهان به این بیماری مبتلا هستند و بیشترین شیوع آن در بالغین جوان است . یکی از شایعترین علایم ms ، خستگی می باشد که حدود 90 % بیماران به آن دچارند. با وجودیکه fatigue ، شایعترین علت ناتوانی بیماران ms می باشد ، هنوز پزشکان در تشخیص و درمان آ...
The decomposition of the tensor product of a positive and a negative discrete series representation of the Lie algebra su(1, 1) is a direct integral over the principal unitary series representations. In the decomposition discrete terms can occur, and the discrete terms are a finite number of discrete series representations or one complementary series representation. The interpretation of Meixne...
This paper characterizes the first cohomology group H(G,M) where M is a Banach space (with norm || ||M) that is also a left CG module such that the elements of G act onM as continuous C-linear transformations. We study this group for G an infinite, finitely generated group. Of particular interest are the implications of the vanishing of the group H(G,M). The first result is that H(G,CG) imbeds ...
The non-relativistic quark model has been a useful tool in the study of hadrons. Baryons and mesons are described by quantum mechanical wavefunctions for nonrelativistic constituent quarks. The lowest lying baryons, the 81/2 and 103/2, are three quark states with wavefunctions which are completely antisymmetric in color, and completely symmetric in position and spin-flavor. The properties of ba...
We present a program that allows for the computation of tensor products of irreducible representations of Lie algebras A−G based on the explicit construction of weight states. This straightforward approach (which is slower and more memoryconsumptive than the standard methods to just calculate dimensions of the tensor product decomposition) produces Clebsch-Gordan coefficients that are of intere...
After careful introduction and discussion of the concepts involved, procedures are developed to compute Racah and Clebsch-Gordan coefficients for general r-fold tensor products of the U(N) groups. In the process, the multiplicity of a given irreducible representation (irrep) in the direct sum basis is computed, and generalized Casimir operators are introduced to uniquely label the multiple irre...
We study the tensor category of modules over a semisimple bialgebra H under the assumption that irreducible H -modules of the same dimension >1 are isomorphic. We consider properties of Clebsch–Gordan coefficients showing multiplicities of occurrences of each irreducible H -module in a tensor product of irreducible ones. It is shown that, in general, these coefficients cannot have small values....
PURPOSE To evaluate the association between the density of nuclear, cortical, and posterior subcapsular lens opacities and visual impairment in patients with cataract. METHODS In 80 patients, visual acuity and reading performance were evaluated 1 day before and 4 weeks after cataract surgery. Cataracts were categorized and graded according to the Lens Opacities Classification System (LOCS) II...
مقدمه : سرطان سینه از جمله شایعترین بدخیمی ها در زنان ایرانی می باشد که میزان بروز آن 09/17% در هر 100 هزار زن می باشد. میزان بقای 5 ساله این بدخیمی در حدود 75% گزارش شده است. سرطان پستان شایعترین علت مرگ در زنان پس از سرطان ریه بوده و شایعترین محل درگیری آن در ربع فوقانی-خارجی سینه می باشد. مبتلایان به سرطان سینه به دلیل مصرف داروهای مختلف از جمله مهارکننده های آروماتاز در معرض ابتلا به کاهش چ...
