Estimation of Underlying Normal Distribution Parameters From Dichotomized Data

Biometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT Accurately estimating the parameters of a continuous distribution from dichotomized or aggregated data is a common problem in biomedical and environmental research. Many studies report only the proportion of subjects exceeding a threshold, without releasing individual‐level measurements.

Edge‐Based Discretizations on Triangulations in Any Dimension, With Special Attention to Four‐Dimensional Space

International Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1143-1164, October 2026.
This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...

A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1991-2003, October 2026.
ABSTRACT PurposeTo enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. MethodsThe custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore ...

Simultaneous 3‐D Adiabatic T1ρ, T2*, and Quantitative Susceptibility Mapping for Characterization of Myocardial Infarction in Ex Vivo Mouse

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
This study combines segmented T1ρ preparation into a 3‐D gradient‐echo sequence for simultaneous quantitative susceptibility, T2*, and T1ρ mapping of infarcted mouse hearts ex vivo. The method enabled assessment of T1ρ and T2* relaxation time maps and magnetic susceptibility, with ischemic regions clearly identified by all contrasts and consistent with

A Machine Learning Approach That Measures Extracellular pH Within an In Vivo Tumor Model Using acidoCEST MRI

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Machine learning models, particularly RFR (random forest regression), provide accurate and computationally efficient tumor pHe estimation from acidoCEST MRI without requiring auxiliary parametric maps. RFR achieved comparable performance to traditional Bloch fitting (RMSE: 0.020 vs.
