The explicit double sum for the associated Laguerre polynomials is derived combinatorially. The moments are described using certain statistics on permutations and permutation tableaux. Another derivation of the double sum is provided using only the moment generating function.
During derivation of transgenic mouse strains with various TL and TL/H-2 chimeric genes, one strain, Tg.Tlaa-3-1, introduced with a TL gene (Tlaa-3), was found to have an abnormal thymic T cell population and to develop a high incidence of T cell lymphomas. To investigate the etiology of the thymic abnormalities and of the lymphomas, the development of lymphoid organs in transgenic mice was stu...
Let A and B be Banach algebras and B be a right A-module. In this paper, under special hypotheses we prove that every pseudo (n+1)-Jordan homomorphism f:A----> B is a pseudo n-Jordan homomorphism and every pseudo n-Jordan homomorphism is an n-Jordan homomorphism
In this talk, I survey several Q-linear relations for multiple L-values of Arakawa-Kaneko type. T. Arakawa and M. Kaneko proved in 2004 the so-called derivation relation, which is proved as a corollary of the regularized double shuffle relation. Kaneko firstly formulated an extension of the derivation relation by modeling a Hopf algebra introduced by A. Connes and H. Moscovici. G. Kawashima and...
Recombination between moderately divergent DNA sequences is impaired compared with identical sequences. In yeast, an HO endonuclease-induced double-strand break can be repaired by single-strand annealing (SSA) between flanking homologous sequences. A 3% sequence divergence between 205-bp sequences flanking the double-strand break caused a 6-fold reduction in repair compared with identical seque...
In mammalian cells, DNA double-strand breaks (DSBs) cause rapid phosphorylation of the H2AX core histone variant (to form gamma-H2AX) in megabase chromatin domains flanking sites of DNA damage. To investigate the role of H2AX in mammalian cells, we generated H2AX-deficient (H2AX(Delta)/Delta) mouse embryonic stem (ES) cells. H2AX(Delta)/Delta ES cells are viable. However, they are highly sensit...
in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...
فضای توپولوژیک $ x $ یک فضای $g _{delta} $-بلمبرگ نامیده می شود اگر برای هر تابع حقیقی مقدار $ f $ از $ x $ یک $g_{delta} $-مجموعه چگال در $ x $ مانند $ d $ وجود داشته باشد به طوری که تحدید $ f $ به $ d $ پیوسته باشد. در این پایان نامه این فضا تحت زیر فضا ها و ابر فضا ها، تصویر ها و تصویر معکوس ها بررسی می شوند و یک فضای $ g_{delta}$-بلمبرگ که تعمیمی از تقریباً $ p $-فض...
CD4 and CD8 have been useful surface markers for alpha/beta T cell maturation. In an alpha/beta T cell receptor (TCR) transgenic SCID mice system, it has been shown that alpha/beta TCR alone is sufficient to induce CD4 and CD8 surface expression on thymic T cells. Although the late embryonic thymic gamma/delta T cells are predominately single and double positive, it has not been clear if gamma/...
