Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1872-1892, October 2026.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.

STHANet: Spatiotemporal Hybrid Attention Network for auditory attention decoding

Journal of Intelligent Medicine, Volume 3, Issue 3, Page 290-301, September 2026.
STHANet integrates depth‐wise spatial filtering, log–variance temporal characterization, and transformer‐based spatiotemporal fusion to model global EEG interactions for direct AAD. Abstract Auditory attention decoding (AAD) aims to detect the target speaker from electroencephalography (EEG) signals in multi‐talker environments.

Using InSAR Coherence to Map Stand Age in a Boreal Forest

Remote Sensing, 2012
The interferometric coherence parameter γ estimates the degree of correlation between two Synthetic Aperture Radar (SAR) images and can be influenced by vegetation structure. Here, we investigate the use of repeat-pass interferometric coherence &

Diagnostic Accuracy of APTw and NOEw MRI Metrics for IDH Mutation and 1p/19q Codeletion Prediction in Gliomas

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
We evaluated how confounding effects from fluid, macromolecules and T1 relaxation impact the performance of APTw and NOEw metrics for noninvasive glioma classification at 3 T. Corrected APTw metrics showed the highest discriminations of IDH‐mutant from wild‐type gliomas (AUC = 0.94–0.96), whereas NOEw metrics did not differ between groups.

Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 560-572, September/October 2026.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Validation of ECMWF Ensemble Forecasts of Sea Surface Latent and Sensible Heat Fluxes in the Pacific Arctic Against Saildrone Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Estimates of sea‐surface latent and sensible heat fluxes using in situ observations are very rare in the Arctic Ocean. Saildrone Explorer uncrewed surface vehicles (saildrones) were deployed in the Bering, Chukchi, and Beaufort Seas from May–October 2019.

Volcanic Eruptions Reorganize Climate Teleconnections: Detection via Riemannian Covariance Fingerprinting

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Standard detection and attribution of volcanic forcing targets spatial temperature anomalies. We show that the covariance structure of climate variability carries an independent volcanic fingerprint. Applying tangent‐space regression on the symmetric positive definite manifold SPD(8) to 40 years of eight teleconnection indices, we detect ...

Demonstration of Spaceborne Multi-static SAR Tomography and Forest Height Estimation

Leida xuebao
Synthetic Aperture Radar Tomography (TomoSAR), by virtue of its three-dimensional (3D) resolution capability, can be used to study the 3D structure of semitransparent targets, such as forests, icebergs, and snowpacks.

Speech Preprocessing Method Based on Transmission Wave and Fluid Theory

Engineering Reports, Volume 8, Issue 8, August 2026.
With the continuous development of social economy, voice audio has become one of the important ways of streaming media, and is widely used in many fields. However, it is very important for how to process speech. In view of this requirement and limitation, this paper introduces transmission wave and fluid theory, tries to comb the corresponding noise ...
