The objective of this paper is to survey the algorithms used for de novo alignment of short read data. Since the quality of the sequence bases which are aligned is important, this paper starts by comparing conventional sequencing methods and next-generation sequencing platforms. Next-generation sequencing poses new challenges to the bioinformatics community. A description of several de novo ali...

Abstract In nonlinear greedy approximation theory, bidemocratic bases have traditionally played the role of dualizing democratic, greedy, quasi-greedy, or almost bases. this article we shift viewpoint and study them for their own sake, just as would with any other kind greedy-type particular show that need not be despite fact they retain a strong unconditionality flavor which brings very close ...

A comparative study of the cleavage efficiency of succinyl, phthaloyl, oxalyl, 2-(2-nitrophenyl)ethyl, 9-fluorenylmethyl, and 2nitrophenyl supports in 0.5M DBU solutions is described. A decrease in cleavage efficiency is observed when small oligonucleotides containing thymidine are linked to the supports. In these conditions oxalyl supports gave the best yields followed by 2-(2-nitrophenyl)ethy...

substituted schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. on cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...

in this paper, we investigate duality of modular g-riesz bases and g-riesz basesin hilbert c*-modules. first we give some characterization of g-riesz bases in hilbert c*-modules, by using properties of operator theory. next, we characterize the duals of a giveng-riesz basis in hilbert c*-module. in addition, we obtain sucient and necessary conditionfor a dual of a g-riesz basis to be again a g...
