On universal quantum dimensions
Nuclear Physics B, 2017 We represent in the universal form restricted one-instanton partition function of supersymmetric Yang–Mills theory. It is based on the derivation of universal expressions for quantum dimensions (universal characters) of Cartan powers of adjoint and some ...

Journal of Applied Crystallography, EarlyView.The weighted agreement factor in small‐molecule crystallography is, for half of a sample (N = 314) of published data sets, so large that it cannot be explained by errors like unrecognized disorder or twinning. Instead, the standard uncertainties are most likely flawed in these cases.The increase in the weighted agreement factor due to systematic errors

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

Biodiversity–food trade‐offs when agricultural land is spared from production
American Journal of Agricultural Economics, EarlyView.Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

Bispectral extensions of the Askey–Wilson polynomials
Journal of Functional Analysis, 2014 Following the pioneering work of Duistermaat and Gr nbaum, we call a family $\{p_n(x)\}_{n=0}^{\infty}$ of polynomials bispectral, if the polynomials are simultaneously eigenfunctions of two commutative algebras of operators: one consisting of difference operators acting on the degree index $n$, and another one of operators acting on the variable $x$.

British Journal of Industrial Relations, EarlyView.ABSTRACT This study investigates how the quality of performance appraisals influences perceptions of merit pay − whether it is viewed as motivating or divisive − and its impact on achieving performance objectives. Using longitudinal survey data collected from classroom teachers in England and Wales between 2014 and 2018, and employing an instrumental ...

Scalar blocks as gravitational Wilson networks
Journal of High Energy Physics, 2018 In this paper we continue to develop further our prescription [ arXiv:1602.02962 ] to holographically compute the conformal partial waves of CFT correlation functions using the gravitational open Wilson network operators in the bulk.

A "missing" family of classical orthogonal polynomials
, 2011 We study a family of "classical" orthogonal polynomials which satisfy (apart from a 3-term recurrence relation) an eigenvalue problem with a differential operator of Dunkl-type.

Terrain descriptors for landscape synthesis, analysis and simulation
Computer Graphics Forum, EarlyView.Abstract Synthetic landscape generation is an active research area within Computer Graphics. Algorithms for terrain synthesis and ecosystem simulations often rely on simple descriptors such as slope, light accessibility, and drainage area. Typically, the results are assessed from a perceptual standpoint, focusing primarily on visual plausibility. Other

Journal of High Energy Physics, 2020 We study a set of CFT operators suitable for reconstructing a charged bulk scalar field ϕ in AdS3 (dual to an operator O $$ \mathcal{O} $$ of dimension ∆ in the CFT) in the presence of a conserved spin-n current in the CFT.
