Bivariate Bannai-Ito polynomials

, 2018
A two-variable extension of the Bannai-Ito polynomials is presented. They are obtained via $q\to-1$ limits of the bivariate $q$-Racah and Askey-Wilson orthogonal polynomials introduced by Gasper and Rahman. Their orthogonality relation is obtained. These

Diagonalization of the Heun-Askey-Wilson operator, Leonard pairs and the algebraic Bethe ansatz

Nuclear Physics B, 2019
An operator of Heun-Askey-Wilson type is diagonalized within the framework of the algebraic Bethe ansatz using the theory of Leonard pairs. For different specializations and the generic case, the corresponding eigenstates are constructed in the form of ...

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

A Relativistic Conical Function and its Whittaker Limits

Symmetry, Integrability and Geometry: Methods and Applications, 2011
In previous work we introduced and studied a function R(a+,a−,c;v,vˆ) that is a generalization of the hypergeometric function _2F_1 and the Askey-Wilson polynomials.

Can prisons move people into better jobs? A look at correctional vocational training programs and sectoral employment outcomes

Criminology, EarlyView.
Abstract Three‐quarters of US prisons offer vocational training programs, which aim to place trainees in middle‐skills jobs in specific occupational sectors post‐release. These middle‐skills jobs may more effectively reduce recidivism than the jobs that normally characterize the labor market experience of the formerly incarcerated, yet whether ...

Contractions of 2D 2nd Order Quantum Superintegrable Systems and the Askey Scheme for Hypergeometric Orthogonal Polynomials

Symmetry, Integrability and Geometry: Methods and Applications, 2013
We show explicitly that all 2nd order superintegrable systems in 2 dimensions are limiting cases of a single system: the generic 3-parameter potential on the 2-sphere, S9 in our listing.

Estimation of Two Component Activities of Binary Liquid Alloys by the Pair Potential Energy Containing a Polynomial of the Partial Radial Distribution Function

Metals, 2023
An investigation of partial radial distribution functions and atomic pair potentials within a system has established that the existing potential functions are rooted in the assumption of a static arrangement of atoms, overlooking their distribution and ...

Environmentally adjusted productivity growth and shadow prices for dairy farms

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Duality Identities for Moduli Functions of Generalized Melvin Solutions Related to Classical Lie Algebras of Rank 4

Advances in Mathematical Physics, 2018
We consider generalized Melvin-like solutions associated with nonexceptional Lie algebras of rank 4 (namely, A4, B4, C4, and D4) corresponding to certain internal symmetries of the solutions.

Generalized Dyck tilings (Extended Abstract) [PDF]

Discrete Mathematics & Theoretical Computer Science, 2014
Recently, Kenyon and Wilson introduced Dyck tilings, which are certain tilings of the region between two Dyck paths. The enumeration of Dyck tilings is related with hook formulas for forests and the combinatorics of Hermite polynomials. The first goal of
