Sampling of non‐Gaussian Ensemble Average Propagators for the simulation of diffusion magnetic resonance images

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1255-1265, February 2026.
Abstract Purpose (a) To design a methodology for drawing random samples of any Ensemble Average Propagator (EAP) (b) to modify the KomaMRI simulator to accommodate them as realistic spin movements to simulate diffusion MRI (dMRI) and (c) to compare these simulations with those based on the Diffusion Tensor (DT) model.

Water use and productivity of Cannabis sativa L., KwaZulu-Natal Midlands, South Africa

Journal of Cannabis Research
Aims The South African National Water Act (No. 36 of 1998) mandates the regulation of land-based activities that reduce streamflow by declaring them streamflow reduction activities (SFRAs). Hemp (Cannabis sativa L.) is commonly known as a water-intensive

ISME—incoherent sampling of multi‐echo data to minimize cardiac‐induced noise in brain maps of R2*$$ {R}_2^{\ast } $$ and magnetic susceptibility

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 897-911, February 2026.
Abstract Purpose Maps of the MRI parameters R2*$$ {\mathrm{R}}_2^{\ast } $$ and magnetic susceptibility (χ$$ \chi $$) enable the investigation of microscopic tissue changes in brain disease. However, cardiac‐induced signal instabilities increase the variability of brain maps of R2*$$ {\mathrm{R}}_2^{\ast } $$ and χ$$ \chi $$.

High‐Latitude Eddy Covariance Temporal Network Design and Optimization

Journal of Geophysical Research: Biogeosciences
AbstractEcosystems at high latitudes are changing rapidly in response to climate change. To understand changes in carbon fluxes across seasonal to multi‐decadal timescales, long‐term in situ measurements from eddy covariance networks are needed. However, there are large spatiotemporal gaps in the high‐latitude eddy covariance network.

Processes Governing the Ablation of Intercepted Snow

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Interception and ablation of snow in forest canopies significantly influence the quantity, timing, and phase of precipitation that reaches the ground in cold regions forests. Yet current modeling approaches have uncertain transferability across differing climate and forest types.

Multiscale Assessment of the Water Balance Components in Arizona Simulated by the National Water Model

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT Arizona, located in the Desert Southwest of the U.S., faces chronic water scarcity and has been strongly affected by the multidecadal Millennium Drought. As the state increasingly turns to water augmentation strategies, accurate, high‐resolution estimates of water balance components are essenctial.
