in this article, we introduce monomial irreducible representations of the special linear lie algebra $sln$. we will show that this kind of representations have bases for which the action of the chevalley generators of the lie algebra on the basis elements can be given by a simple formula.

Long-chain bases (sphingoids or sphingoid bases) are the characteristic or defining structural unit of the sphingolipids. The bases are long-chain aliphatic amines, containing two or three hydroxyl groups, and often a distinctive trans-double bond in position 4. To be more precise, they are 2-amino-1,3-dihydroxy-alkanes or alkenes with (2S,3R)-erythro stereochemistry, with various further struc...

although triple (omeprazole, amoxicillin, and metronidazole) and quadruple (omeprazole, tetracycline, metronidazole, and bismuth subcitrate) therapeutic regimens for h. pylori eradication has been studied much in the general population, there is a lack of data in renal transplanted patients. so, this study aimed at comparing regimens in these patients who were considered being immunocompromised...

The synthesis and properties of triplex-forming DNA clamps carrying 8-aminopurines are described. The stability of triple helices is enhanced by replacing purine bases with 8-aminopurine residues. These enhanced binding properties are used for the specific capture of polypyrimidine RNA/DNA sequences of interest.

It was shown that linked systems of symmetric designs with a1 = 0 and mutually unbiased bases (MUBs) are triply regular association schemes. In this paper, we characterize triple regularity of linked systems of symmetric designs by its Krein number. And we prove that a maximal set of MUBs carries a quadruply regular association scheme and characterize the quadruple regularity of MUBs by its par...

We propose the existence of a novel base triple in the HIV-1 TAR hairpin. This triple is supported by covariation of loop residue 31 with residue 22, which is part of an unusual base pair with U40 below the 3-nucleotide bulge. A set of mutants was constructed to test the involvement of bases A22, U31, and U40 in a triple interaction. RNA structure probing, trans-activation assays, and structure...

Hallin and Ley (2012) investigate and fully characterize the Fisher singularity phenomenon in univariate and multivariate families of skew-symmetric distributions. This paper proposes a refined analysis of the (univariate) Fisher degeneracy problem, showing that it can be more or less severe, inducing n (“simple singularity”), n (“double singularity”), or n (“triple singularity”) consistency ra...
