Virtual Mirror Verification of Heterogeneous Data Based on Spatio‐Temporal Coupling Graph Convolution Compressed Sensing Model

Engineering Reports, Volume 8, Issue 4, April 2026.
The smart grid digital twin architecture with linkage function proposed in this paper integrates a spatio‐temporal–physical coupling mechanism and an online adaptive learning framework, and the algorithm flow is shown in Figure. ABSTRACT The digital management of distribution transformer areas in smart grids faces several core challenges. These include

Causal Inference for Geostatistical Data Using an INLA‐based Spatial Propensity Score

Environmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT In this paper, we propose a Bayesian approach for spatial causal inference based on combining spatial propensity scoring with Integrated Nested Laplace Approximation. The method models both local and spillover exposure effects via multiple likelihoods and treats counterfactuals as missing data, allowing inference also for non‐Gaussian outcomes.

Deep Quake Dynamics: A Multimodal Fault‐Aware Approach to Earthquake Magnitude and Occurrence Time Forecasting

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
EQMT integrates earthquake catalog data, fault‐network geometry, engineered features, and graph embeddings in a unified framework for forecasting earthquake magnitude and occurrence time. The framework is designed to reflect inter‐fault spatial dependencies together with temporal seismic patterns, addressing limitations of approaches based only on ...

On the role of demagnetizing tensors in arbitrary orientations of general ellipsoids and implications for MRI safety assessment

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Demagnetizing tensors describe the shape anisotropic contribution of magnetic susceptibility, that is, how an object's shape and orientation affect its internal magnetization. Ellipsoids possess a unique geometric property by exhibiting homogeneous internal magnetization, enabling a purely geometrical characterization.

Quantitative Susceptibility Mapping in Skull Base Chordoma: In Silico Analysis and In Vivo Application Towards Indirect Hypoxia Assessment

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2092-2105, April 2026.
ABSTRACT Purpose To evaluate quantitative susceptibility mapping (QSM) beyond the brain through realistic simulations and to explore preliminary evidence that may be indicative of hypoxia in skull base chordomas (SBC). Methods Each step of the QSM pipeline was optimized within an in silico framework consisting of (i) phase unwrapping, (ii) background ...

RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2331-2344, April 2026.
ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.
