We reformulate free equations of motion for massive spin 0 and spin 1/2 matter fields in 2+1 dimensional anti-de Sitter space in the form of some covariant constantness conditions. The infinite-dimensional representation of the anti-de Sitter algebra underlying this formulation is shown to admit a natural realization in terms of the algebra of deformed oscillators with a deformation parameter r...

Nonsuppressible insulin-like activity soluble in acid ethanol (NSILA-s) is a well-characterized peptide derived from human serum which has previously been shown to have insulin-like bioactivity and react with both insulin and NSILA-s receptor sites in liver plasma membranes. In the present study we find that NSILA-s is also a potent competitive inhibitor of the insulin-degrading system of the l...

Integrability of Quantum Chromodynamics in 1+1 dimensions has recently been suggested by formulating it as a perturbed conformal Wess-Zumino-Witten theory. The present paper further elucidates this formulation, by presenting a detailed BRST analysis. CONICET, Argentina Investigador CICBA

We discuss general properties of the conservation law associated with a local symmetry. Using Noether's theorem and a generalized Belinfante symmetrization procedure in 3+1 dimensions, a symmetric energy-momentum (pseudo) tensor for the gravitational Einstein-Hilbert action is derived and discussed in detail. In 2+1 dimensions, expressions are obtained for energy and angular momentum arising in...

Bone like hydroxyapatite (nHAp) was synthesized via an in situ biomimetic process in presence of wheat starch. The effect of polymer concentration alteration on the final structure of nHAp was investigated. Formation of the nHAp at room temperature was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the nHAp samples were character...

به طور کلی در فرآیندهای مارکوف ارگودیک دو بعدی یافتن فرم بسته توزیع ایستا، تنها برای حالات خیلی خاص امکان پذیر است. با توجه به این مشکل و نیز با توجه به اهمیت توزیع ایستا، بررسی و مطالعه رفتار مجانبی توزیع ایستای این فرآیندها مورد توجه قرار گرفته است. زنجیر قدم زدن تصادفی دو بعدی که در برخی متون به آن، فرآیند qbd دو طرفه نیز می گویند، یکی از این فرآیندها است. یک فرآیند qbd زمان گسسته یک زنجیر م...

Background and purpose: Spermatogenesis is a well-organized process that is influenced by a variety of factors. Alkaline phosphatase, and Gfra1, Lin28, and Sall4 genes are among the key players in this interconnected process. This study aimed to investigate the expression levels of Gfra1, Lin28, and Sall4 genes in embryonic, spermatogonial, and embryonic stem-like (ES-like) cells in mice. Mate...
