Constructing Pseudo-involutions in the Riordan Group
Candice Marshall, Asamoah Nkwanta
Riordan arrays, denoted by pairs of generating functions (g(z), f(z)), are infinite lower-triangular matrices that are used as combinatorial tools. In this paper, we present Riorda…
Catalan and Motzkin Integral Representations
Peter McCalla, Asamoah Nkwanta
We present new proofs of eight integral representations of the Catalan numbers. Then, we create analogous integral representations of the Motzkin numbers and obtain new results. Mo…
Riordan Matrix Representations of Euler's Constant and Euler's Number
Edray Herber Goins, Asamoah Nkwanta
We show that the Euler-Mascheroni constant and Euler's number can both be represented as a product of a Riordan matrix and certain row and column vectors.
A contact-waiting-time metric and RNA folding rates
Asamoah Nkwanta, Wilfred Ndifon
Metrics for indirectly predicting the folding rates of RNA sequences are of interest. In this letter, we introduce a simple metric of RNA structural complexity, which accounts for…
An RNA foldability metric; implications for the design of rapidly foldable RNA sequences
W. Ndifon, A. Nkwanta
Evidence is presented suggesting, for the first time, that the protein foldability metric sigma=(T_theta - T_f)/T_theta, where T_theta and T_f are, respectively, the collapse and f…
