Biodiversity–food trade‐offs when agricultural land is spared from production

open access: yesAmerican 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 ...

Chern-Simons perturbative series revisited

open access: yesPhysics Letters B, 2021
A group-theoretical structure in a perturbative expansion of the Wilson loops in the 3d Chern-Simons theory with SU(N) gauge group is studied in symmetric approach.

Exact correlators on the Wilson loop in N = 4 $$ \mathcal{N}=4 $$ SYM: localization, defect CFT, and integrability

open access: yesJournal of High Energy Physics, 2018
We compute a set of correlation functions of operator insertions on the 1/8 BPS Wilson loop in N = 4 $$ \mathcal{N}=4 $$ SYM by employing supersymmetric localization, OPE and the Gram-Schmidt orthogonalization.

Bootstrapping and Askey-Wilson polynomials [PDF]

open access: yesarXiv, 2014
The mixed moments for the Askey-Wilson polynomials are found using a bootstrapping method and connection coefficients. A similar bootstrapping idea on generating functions gives a new Askey-Wilson generating function. An important special case of this hierarchy is a polynomial which satisfies a four term recurrence, and its combinatorics is studied.

Appraisal Process, Merit Pay and Performance: Evidence From a Longitudinal Survey of School Teachers in England and Wales

open access: yesBritish 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 ...

General solutions and applications of the coupled Drinfel’d–Sokolov–Wilson equation

open access: yesExamples and Counterexamples, 2023
We report a new batch of wave solutions for the coupled Drinfel’d–Sokolov–Wilson equation which represents a coupled system of nonlinear partial differential equations (NLPDEs).

Addition formula for 2-parameter family of Askey-Wilson polynomials [PDF]

open access: yesarXiv, 1994
For a two parameter family of Askey-Wilson polynomials, that can be regarded as basic analogues of the Legendre polynomials, an addition formula is derived. The addition formula is a two-parameter extension of Koornwinder's addition formula for the little $q$-Legendre polynomials. A corresponding product formula is derived.

Integral Representations of the Wilson Polynomials and the Continuous Dual Hahn Polynomials

open access: yesAdvances in Applied Mathematics, 1999
AbstractWe give representations of the Wilson polynomials and the continuous dual Hahn polynomials in terms of multidimensional generalizations of Barnes type integrals. Motivation is to study the Barnes type integrals from the viewpoint of the de Rham theory and holonomic systems.

On the Line and Online: Higher Non‐Response to Web‐Based Surveys Over‐Represents Avid Recreational Fishers Compared With Telephone Surveys

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fishing surveys have an important role in providing data to inform fisheries management. The selection of a contact method is an important and often challenging consideration that influences the potential for non‐sampling errors that can result in unrepresentative data and biased estimates.
