Production Gaps Among Farmers With Disabilities Are Associated With Limited Technology

Agricultural Economics, Volume 57, Issue 4, July 2026.
ABSTRACT In sub‐Saharan Africa, agriculture is vital; however, the systematic exclusion of persons with disabilities from farming hinders sustainable development and social equity. Although several studies have analyzed productivity differentials across various dimensions of social exclusion, empirical evidence on technology access, farming efficiency,

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Daytime Ionospheric F‐Region Topside Irregularities Associated With Significant Density Enhancement at Low Latitudes During the 12 November 2025 Magnetic Storm

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract In this study, daytime F‐region irregularities were observed at low latitudes during the main phase of the 12 November 2025 strong magnetic storm, causing intense very high frequency radar echoes ranging hundreds of kilometers in altitude.

Dynamic Coupling Between Faulting, Rifting and Magmatism During 2021‐2025 Unrest on Reykjanes Peninsula, Iceland

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Interactions among faulting, earthquakes, and eruptions are fundamental to plate tectonics and hazard forecasting yet rarely observed along mid‐ocean ridges. On Iceland's Reykjanes Peninsula, seismotectonic–volcanic unrest resumed after nearly 800‐year hiatus, providing an opportunity to observe these interactions during 2021–2025 activity. By

Direct Ionosonde Evidence of F‐Layer Disturbances Driven by Intense Lightning Activity at Low Latitudes

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Thunderstorms could cause the irregularities of electron density distributions in the ionosphere by exciting gravity waves and modifying ambient electric field (E‐field). By comparing the DPS‐4D ionosonde observation at 5‐min resolution at Fuke Station in Hainan, China with the lightning detection data, we studied the F‐layer responses to a ...

Temporal Variations in Seismic Ambient Noise Identify Seasonal Changes in Basal Conditions at Sermeq Kujalleq in Kangia, Greenland

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Subglacial processes are key to glacier dynamics but remain poorly constrained due to limited in situ observations. We use continuous seismic and Global Navigation Satellite System (GNSS) measurements to investigate summer basal conditions at Sermeq Kujalleq in Kangia (SKK; Jakobshavn Isbræ), Kalaallit Nunaat (Greenland).

Crustal Responses to the Destruction of Continental Lithosphere: Insights From Radial Anisotropy of the Tanlu Fault Zone, Eastern China

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

Machine Learning‐Based Analysis of Atmospheric Process Sensitivity to Land Surface Properties Over Complex Terrain

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract This study investigates the sensitivity of numerical simulations of atmospheric processes over complex terrain to land surface model (LSM) parameters, focusing on thermally driven circulations in an idealized valley. The sensitivity analysis is performed using the Weather Research and Forecasting model coupled with the Noah‐MP LSM, for forest ...

Lightning Outbreaks at the Mature Stage of Tropical Cyclone: Case Study for Hurricane Dorian (2019)

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The relationship between tropical cyclone (TC) lightning activity and intensity change has been examined for nearly 30 years, yet a clear consensus remains elusive, reflecting the complexity of the processes governing TC lightning. This study investigates the physical mechanisms that triggered inner‐core lightning outbreaks during the mature ...
