Assessing Magnetic Fluctuations Effects in the South American Sector in Relation to Global Variations Using Ksa Index, Kp Index, and Hybrid Formats During Quiet Times Across the Seasons of the 2020 Solar Minimum

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Geomagnetic indices can be used to quantify variations in geomagnetic activity caused by Sun‐Earth interactions across the magnetosphere and ionosphere. The global Kp index is widely used as a global geomagnetic indicator, but it is based mostly on the Northern Hemisphere with no contributions from South American observatories.

The Role of Basal Roughness and Assemblage Grain‐Size Distribution in Shaping Granular Rheology and Basal‐Force Signals

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.

Bounds of Different Integral Operators in Tensorial Hilbert and Variable Exponent Function Spaces

Mathematics
In dynamical systems, Hilbert spaces provide a useful framework for analyzing and solving problems because they are able to handle infinitely dimensional spaces.

Observation‐Driven Forecast of Global Terrestrial Water Storage and Evaluation for 2010–2024

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE/‐FO) satellite missions have provided unprecedented measurements of terrestrial water storage changes (TWSC). These data are essential for monitoring the global water cycle, supporting drought and flood risk management, and informing water‐related ...

Weighted Quasi-Arithmetic Means and the Domain Translations

Journal of Advanced Computational Intelligence and Intelligent Informatics, 2012
The monotonicity of the weighted quasi-arithmetic means is discussed from the viewpoint of utility functions and weighting functions. Observing the indices given by utility functions and weighting functions, we find that these indices give similarmonotonicity for the weighted quasi-arithmetic means, and this paper investigates the reason using the ...

Do Adverse Events Influence Time Preferences? Evidence From Smallholder African Farmers

Journal of Agricultural Economics, Volume 77, Issue 1, Page 130-155, February 2026.
ABSTRACT Time preferences play a critical role in the agri‐food value chains of low‐income countries, impacting the choices of local operators, including innovation uptake. This paper assesses the association between smallholder farmers' individual characteristics, their exposure to diverse adverse events, and their intertemporal choices using in‐the ...

Has Research on “What Works” in Education Been Looking at the Wrong Interventions? Revisiting “Why ‘What Works’ Won't Work”

Educational Theory, Volume 76, Issue 1, Page 16-24, February 2026.
Abstract In this invited article, I revisit my 2007 essay “Why ‘What Works’ Won't Work: Evidence‐Based Practice and the Democratic Deficit in Educational Research.” I provide a summary of the key arguments in the essay, explain why I used the phrase “democratic deficit,” examine what I have observed regarding the discussion about “evidence” in ...

Hypergeometric motives from Euler integral representations

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We revisit certain one‐parameter families of affine covers arising naturally from Euler's integral representation of hypergeometric functions. We introduce a partial compactification of this family. We show that the zeta function of the fibers in the family can be written as an explicit product of L$L$‐series attached to nondegenerate ...

On Multilevel Energy‐Based Fragmentation Methods

International Journal of Quantum Chemistry, Volume 126, Issue 3, January 30, 2026.
We investigate the working equations of energy‐based fragmentation methods and present ML‐SUPANOVA, a Möbius‐inversion‐based multilevel fragmentation scheme that enables adaptive, quasi‐optimal truncations to efficiently approximate Born‐Oppenheimer potentials across hierarchies of electronic‐structure methods and basis sets.
