The leftmost column entries of RNA arrays I and II count the numbers that are related to secondary structures from molecular biology. sometimes have mutations wobble pairs. Mutations random changes occur in a structure, pairs known as non-Watson–Crick base We used topics combinatorics Riordan array theory establish connections among combinatorial objects linear trees, lattice walks, arrays. In ...

In this paper, we present a novel approach to compute ambiguities in thinned uniform linear arrays, i.e., sparse non-uniform via mixed-integer program. Ambiguities arise when there exists set of distinct directions-of-arrival, for which the corresponding steering matrix is rank-deficient and are associated with nonunique parameter estimation. Our uses Young tableaux submatrix has vanishing dete...

Mammalian artificial chromosomes (MACs) form in HT1080 cells after transfecting linear yeast artificial chromosome constructs minimally containing competent alphoid arrays, a selectable marker and terminal human telomere repeats. Restrictions on the structure of input DNA in MAC formation were investigated by transfecting circular or linear alphoid constructs with or without human telomere arra...

In this paper, a new method is proposed for calibrating a planar array of general geometry with respect to errors in location, phase and gain, even when all errors are present simultaneously (global calibration). The method requires the use of three pilot sources, which operate one at a time and from at least two different azimuth angles. Since the sources need not operate simultaneously, one o...
