Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

G‐optimal grid designs for kriging models

Scandinavian Journal of Statistics
AbstractThis work is focused on finding G‐optimal designs theoretically for kriging models with two‐dimensional inputs and separable exponential covariance structures. For design comparison, the notion of evenness of two‐dimensional grid designs is developed.

Mapping forest aboveground carbon stock of combined stratified sampling and RFRK model with mean annual temperature and precipitation

Scientific Reports
Accurately estimating forest aboveground carbon stock (ACS) is essential for achieving carbon neutrality. At present, most non-parametric models still have errors in estimating carbon stock in regions.

Precision and blanket aerification effects on spatial variability of surface hardness in turfgrass sports fields

Agronomy Journal, Volume 118, Issue 6, November/December 2026.
Abstract Sports field surface hardness is spatially and temporally variable, and evidence suggests this variability can influence athlete perceptions, performance, and injury risk. Management strategies addressing within‐field variability, rather than mean hardness alone, are therefore needed.

Vibration Analysis and Optimization of Iron-Core Reactors Based on Fe-Based Soft Magnetic Composite Materials

IEEE Access
To effectively reduce the vibration of iron-core reactors, a vibration optimization method considering the magnetostrictive properties of Fe-based soft magnetic composite materials is proposed.

Accounting for Biases in the Analysis of Building Damage Data for the 2023 M7.8 Türkiye/Syria Earthquake Sequence

Earthquake Spectra, Volume 42, Issue 4, November 2026.
In the aftermath of a large earthquake, several practical constraints affect the systematic collection of data for assessing building damage. The available data are therefore typically incomplete, frequently missing key information such as the type of construction, age and geographic location.

Gaussian process regression of HDR prostate biopsy dose for improved modelling of localization‐induced uncertainty

Medical Physics, Volume 53, Issue 11, November 2026.
Abstract Background Biopsy‐level dose interpretation after high‐dose‐rate prostate brachytherapy is limited by localization uncertainty, and separate voxelwise Monte Carlo summaries do not explicitly account for the axial spatial correlation present along a biopsy core.

Spatial and vertical variability of soil physico‐hydraulic properties and subsurface lithology in the Upper Indus Plain of Pakistan

Vadose Zone Journal, Volume 25, Issue 6, November/December 2026.
Abstract Accurate characterization of soil physico‐hydraulic properties is critical for irrigation and drainage design, solute transport, soil–water–plant, and rainfall–runoff relationships. However, spatially representative datasets for these properties remain limited for the Indus Basin of Pakistan, where hydrological studies often rely on ...
