Exploring the Impacts of Spatial Contexts on the Life Course Trajectory Status of Vulnerability

Geographical Analysis, EarlyView.
ABSTRACT The aim of this study is to investigate in what ways the spatial context matters for the life course trajectory status in terms of vulnerability. In particular, it explores the impacts of spatial contexts aggregated from life course trajectories.

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

Journal 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.

Genetic Evaluation of Barrel Racing Performance in Quarter Horses

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Barrel racing is a competitive timed rodeo event that challenges horses and riders to complete a cloverleaf pattern around three barrels in the fastest time possible. In this study, we aimed to estimate the genetic parameters of barrel racing time (BRT) and evaluate the most suitable statistical model for its analysis.

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

Examples 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).

The quantum superalgebra $\mathfrak{osp}_{q}(1|2)$ and a $q$-generalization of the Bannai-Ito polynomials

, 2015
The Racah problem for the quantum superalgebra $\mathfrak{osp}_{q}(1|2)$ is considered. The intermediate Casimir operators are shown to realize a $q$-deformation of the Bannai-Ito algebra.

Degenerations of Sklyanin algebra and Askey-Wilson polynomials

Journal of Physics A: Mathematical and General, 1993
A new trigonometric degeneration of the Sklyanin algebra is found and the functional realization of its representations in space of polynomials in one variable is studied. A further contraction gives the standard quantum algebra $U_{q}(sl(2))$. It is shown that the degenerate Sklyanin algebra contains a subalgebra isomorphic to algebra of functions on ...

The Influence of Spatial Extent and Distance on Macroinvertebrate‐Environment Relationships in Conterminous USA Stream Sites

Journal of Biogeography, EarlyView.
ABSTRACT Aim The relationships between environmental variables and macroinvertebrate assemblages depend on spatial extent, but the relative importance of local and regional factors remains unclear. Understanding these scale‐dependent relationships is crucial for improving biodiversity assessments and ecosystem management.

Parametric Bootstrap Mantel‐Haenszel Statistic for Aggregated Testlet Effects

Journal of Educational Measurement, EarlyView.
Abstract While testlets have proven useful for assessing complex skills, the stem shared by multiple items often induces correlations between responses, leading to violations of local independence (LI), which can result in biased parameter and ability estimates.

Convolutions for orthogonal polynomials from Lie and quantum algebra representations

, 1996
The interpretation of the Meixner-Pollaczek, Meixner and Laguerre polynomials as overlap coefficients in the positive discrete series representations of the Lie algebra su(1,1) and the Clebsch-Gordan decomposition leads to generalisations of the ...
