SAR Multi-Angle Observation Method for Multipath Suppression in Enclosed Spaces

Remote Sensing
Synthetic aperture radar (SAR) is a powerful tool for detecting and imaging targets in enclosed environments, such as tunnels and underground garages. However, SAR performance is degraded by multipath effects, which occur when electromagnetic waves are ...

1D Pre‐Acquisition Navigator Correcting Respiratory‐Induced Field Fluctuations in Multi‐Echo Gradient‐Echo Imaging of the Thoracic Spinal Cord

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2660-2674, December 2026.
ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

An Open‐Source, Reproducible MRI Data Acquisition and Reconstruction Workflow Using Pulseq: Multi‐Site and Cross‐Vendor Validation

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2721-2738, December 2026.
ABSTRACT Purpose Reproducibility in MRI is limited by variability in data acquisition, formatting, and reconstruction across sites and vendors. This work aimed to mitigate these challenges through an open‐source, vendor‐independent workflow originally developed for the 2023–24 ISMRM Repeat It with Me: Reproducibility Team Challenge.

Servo Navigation and Phase Equalization Enhanced by Run‐Time Stabilization (PEERS) for 3D EPI Time Series

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2739-2754, December 2026.
Purpose To enhance time‐resolved segmented imaging by synergy of run‐time stabilization and retrospective data‐driven phase correction. Methods A segmented 3D EPI sequence for fMRI time series is equipped with servo navigation based on short orbital navigators and a linear perturbation model, enabling run‐time correction for rigid‐body motion, bulk ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, Volume 309, Issue 11, Page 3187-3217, November 2026.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

A computational ghost imaging multi-party collaborative decryption method for low-resolution images

Journal of King Saud University: Computer and Information Sciences
Computational ghost imaging (CGI) is an imaging technique that uses the second-order correlation properties of optical fields. It uses random illumination patterns to illuminate the object, collects the signal via a single-pixel bucket detector, and ...

Automated Quantification of Head Motion Synchrony in Peer Interactions of Autistic and Non‐Autistic Youth

Developmental Science, Volume 29, Issue 6, November 2026.
ABSTRACT Peer interactions take on increasing importance for youth in middle childhood and adolescence. Autistic youth face particular challenges interacting with non‐autistic peers; thus, it is critical to understand factors that predict interaction enjoyment for autistic and non‐autistic youth.

Make Social Media Social Again: How Platform Interoperability Can Fix Social Media and Future‐Proof Democracy

Journal of Management Studies, Volume 63, Issue 7, Page 4425-4453, November 2026.
Abstract This essay argues that social media document (rather than fuel) the decline of political democracy while helping revive organizational democracy, including through ‘decentralized autonomous organizations’ (DAOs). Yet, despite giving everyone a voice and the ability to organize across borders, social media could over‐concentrate power if, in ...

High‐Speed Active Imaging Based Target Deviation Measurement and Optical Calibration for Laser Screen Velocimetry Systems

Advanced Photonics Research, Volume 7, Issue 10, October 2026.
A high‐speed active imaging methodology resolves photoelectric response inconsistencies in laser screen velocimetry. By converting unobservable triggering deviations into quantifiable pixel displacements, this approach enables direct in situ spatial calibration of virtual detection screens.
