Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Testing Hypotheses of Covariate Effects on Topics of Discourse

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 2, April 2026.
ABSTRACT We introduce an approach to topic modeling with document‐level covariates that remains tractable in the face of large text corpora. This is achieved by de‐emphasizing the role of parameter estimation in an underlying probabilistic model, assuming instead that the data come from a fixed but unknown distribution whose statistical functionals are

Series de Dirichlet

open access: yes, 2016
Las series de potencias constituyeron una herramienta esencial manejada por Weierstrass en el siglo XIX dentro de su programa de aritmetización del Análisis Matemático. Más tarde, a principios del siglo XX, en conexión con la función zeta de Riemann se inició un estudio intensivo de las series de Dirichlet, que constituyen el objeto fundamental de este

Race‐related research in economics

open access: yesEconomica, Volume 93, Issue 370, Page 403-438, April 2026.
Abstract Issues of racial justice and economic inequalities between racial and ethnic groups have risen to the top of public debate. Economists' ability to contribute to these debates is based on the body of race‐related research. We study the volume and content of race‐related research in economics.

Multi‐Task Learning for Airport Surface Surveillance: A Review

open access: yesExpert Systems, Volume 43, Issue 4, April 2026.
ABSTRACT The rapid growth of air transportation has surpassed the capabilities of traditional airport surveillance methods, such as visual observation and auxiliary equipment (e.g., ADS‐B, MLAT, radar), which struggle to provide all‐area, all‐weather situation awareness.
