A Statistical Shape Modeling Approach for the Derivation of a Data‐Driven Geometry‐Aware Lumped Arterial Stenosis Model

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 2, February 2026.
A data‐driven workflow for constructing a geometry‐aware lumped arterial stenosis model: Statistical shape modeling extracts geometry‐specific shape modes from synthetically generated coronary lesion geometries. Large‐scale 3D CFD simulations over varying Reynolds numbers yield the geometries their viscous (Kv) and inertial (Kt) loss coefficients. Then,

Scalable spokes pTx pulses for 2D turbo‐spin‐echo imaging at 7 T

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 740-755, February 2026.
Abstract Purpose Turbo spin echo (TSE) is important clinically. Unfortunately, 7 T TSE suffers from B1+‐induced signal dropouts. Magnitude‐based parallel transmit (pTx) pulse design algorithms cannot enforce phase patterns complying with the Carr‐Purcell‐Meiboom‐Gill conditions (90° phase shift between excitation and refocusing).

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Addressing Known Challenges in Solar Flare Forecasting I: Limb‐Flare Prediction With a 4π Full‐Heliosphere Framework

Space Weather, Volume 24, Issue 2, February 2026.
Abstract A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming, we develop a “4π $4{\uppi }$” full‐heliosphere event forecasting framework and evaluate its statistical classification ability against this specific challenge.

Ensemble Methods for History Matching and Uncertainty Quantification With a Watershed Model

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT History matching of large hydrologic models is challenging due to data sparsity and non‐unique process combinations (and associated parameters) that can produce similar model predictions. We develop an ensemble‐based history matching (and uncertainty quantification) approach using an iterative ensemble smoother (iES) method for three cutouts ...

Looking Back to 1991 Economic Forecasting: Introducing Cointegration

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 1, Page 1-21, February 2026.
ABSTRACT Originally written in 1991 to advance the formal analysis of macroeconomic forecasting models and methods following the development of cointegration, alternative forecasting devices, conditional and unconditional forecasts, and data accuracy are considered.
