Double Asymmetric Spin Echo EPI (dASE‐EPI) Enables fMRI of the Entire Rat Brain at 9.4 T

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 366-373, July 2026.
ABSTRACT Purpose Development and evaluation of a double asymmetric spin echo planar imaging (dASE‐EPI) sequence to balance sensitivity to blood oxygenation level‐dependent (BOLD) contrast with mitigation of susceptibility‐induced intravoxel spin dephasing in ultra high‐field rodent brain imaging.

Incorporating Spatial Information in Entropy‐Weighted Composite Indicators: An Application to Education and Training in Italy

Geographical Analysis, Volume 58, Issue 3, July 2026.
ABSTRACT This study introduces a novel methodology in which a composite indicator derived using the Entropy Weight Method is decomposed into a location‐specific component and a spatial component. Although EWM is widely recognized for its robustness in constructing data‐driven composite indicators, standard applications typically overlook spatial ...

Causal Effect Estimation With TMLE: Handling Missing Data and Near Violations of Positivity

Biometrical Journal, Volume 68, Issue 3, June 2026.
ABSTRACT We evaluate the performance of targeted maximum likelihood estimation (TMLE) for estimating the average treatment effect in missing data scenarios under varying levels of positivity violations. We employ model‐ and design‐based simulations, with the latter using undersmoothed highly adaptive lasso on the “WASH Benefits Bangladesh” data set to ...

Creating Flood Disasters: Environmental Memory and Adaptation in Aotearoa New Zealand

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
This article explores three questions. First, why does New Zealand have widespread flooding hazards? Second, why are these persistent, with little seemingly learned from the memory of earlier events? And third, beyond reiterating conventional solutions, what examples of alternatives or adaptations are being developed in different places?

Absolute Quantification of Brain Deuterium Metabolic Imaging in Healthy Volunteers and Glioblastoma Patients at 7T

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3077-3094, June 2026.
ABSTRACT Purpose We present a method for absolute quantification of deuterated metabolites in vivo at 7T. We describe acquisition protocols and an analysis pipeline compatible with 7T Terra MRIs. We apply them using a 2H/1H receive array in healthy volunteers and glioblastoma patients.

Hierarchical Bayesian Modelling Improves Microstructural Parameter Mapping in Diffusion and Exchange MRI Data

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
Our hierarchical Bayesian modelling (HBM) technique is demonstrated in two neuroimaging diffusion MRI models. When compared with least‐squares (LSQ) minimisation, HBM increased the accuracy, precision, contrast‐to‐noise ratio and parameter map quality in simulated and human data. HBM also resolved local parameter variations associated with white matter
