A Semi‐Resolved LES‐DEM Framework for Turbulent Bedload Transport From Saltation to Sheet‐Flow Regimes

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Bedload transport widely occurs in natural environments and encompasses flow regimes from saltation to sheet‐flow, with markedly different fluid‐particle interaction characteristics. Understanding these mechanisms requires a numerical tool capable of capturing both the turbulence and fluid‐particle interactions, for which challenges exist due ...

Testing the Limits of Surface QG Theory With Deep Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Surface Quasi‐Geostrophic (SQG) theory provides a closed‐form mapping from surface buoyancy to interior stream function under the assumption that interior potential vorticity (PV) vanishes (Q=0) $(Q=0)$. In realistic flows, however, the interior PV is typically nonzero.

Rural land rental markets in developing countries: Can survey design innovations improve land market participation statistics?

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 5, Page 1376-1401, October 2026.
Abstract A longstanding puzzle in the African land rental market literature is the often‐observed discrepancy between the number of tenants (renters‐in) and the much smaller number of landlords (renters‐out) in survey data. If this discrepancy derives from systematic biases in survey data responses on rental market participation, then the existing body

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

open access: yesArchaeometry, Volume 68, Issue 5, Page 994-1008, October 2026.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

High School GPA and Exam Scores: Does Their Relevance for First‐Year Academic Performance Vary With Program Selectivity?

open access: yesBulletin of Economic Research, Volume 78, Issue 4, Page 784-802, October 2026.
ABSTRACT This paper examines student admissions to higher education based on past performance, focusing on two measures: high school GPA and national exam scores. GPA is teacher‐assigned and based on repeated assessments, while these exams are externally graded, one‐off standardized tests. Using a nationwide dataset, we investigate how the relevance of
