Exploring Spatial Patterns in Inefficiency Using a Stationary Gaussian Random Field

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This article presents a semiparametric stochastic frontier model that accounts for unobserved spatial heterogeneity in inefficiency by incorporating a stationary Gaussian random field based on geographic coordinates into the inefficiency scaling function. This approach captures spatial patterns in inefficiency at a fine scale.

High‐throughput, high‐fidelity reconstruction of whole mouse‐heart cytoarchitecture at cellular scale

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Experimental workflow of the dual‐camera light‐sheet microscope (dual‐mesoSPIM) pipeline. Intact adult mouse hearts undergo CUBIC‐based delipidation and refractive‐index matching, rendering the whole organ optically transparent (left).

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

Computing Bounds on the Eigenvalues of the Preconditioned X‐FFT System in 3D Linear Elastic Homogenization

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The previously introduced X‐FFT solver permits solving three‐dimensional linear elastic homogenization problems with high accuracy and efficiency. Due to the extended finite element discretization (X‐FEM), matrix‐inclusion problems may be approximated with the error convergence of interface‐conforming finite elements.

Dependence of the Extra‐Cellular Diffusion Coefficient on the Fractions of Neurites and Cell Bodies in Gray Matter

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2426-2439, November 2026.
Purpose The dependence of the long‐time (tortuosity) limit of the extra‐cellular diffusivity on the intra‐cellular volume fraction is of fundamental importance for microstructure modeling. While such dependencies have been explored for the white matter, the tortuosity limit in gray matter is unknown due to complex cell composition and geometry. Here we
