Autonomy for MRI Field Cameras: Synchronization, Self‐Calibration, and Sequence Detection

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 485-498, July 2026.
ABSTRACT Purpose This work aims to provide a workflow for operating NMR field probes in MR scanners independently of pulse programming, scanner TTL trigger pulses and dedicated calibration sequences. Methods An independent timing system and limited prior knowledge about relative probe positions enable synchronous field measurement, probe position ...

Orbit and clock products for quad-system satellites with undifferenced ambiguity fixing approach

Satellite Navigation
Integer Ambiguity Resolution (IAR) can significantly improve the accuracy of GNSS Precise Orbit Determination (POD). Traditionally, the IAR in POD is achieved at the Double Differenced (DD) level.

SELFIE: Self‐Supervised Learning for Fast Dynamic Golden‐Angle Radial MRI

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
SELFIE enables reference‐free reconstruction for dynamic golden‐angle radial MRI. The self‐supervised training is enabled by leveraging the flexible temporal resolution of golden‐angle sampling to create self‐references and temporal sparsity. Evaluated on accelerated DCE‐MRI in patients with gynecological cancer and motion‐resolved free‐breathing ...

From Language Identification to Topic Modelling: A Fully Integrated Pipeline for Multilingual Aspect‐Based Sentiment Analysis and Component‐Level Insights

Expert Systems, Volume 43, Issue 7, July 2026.
ABSTRACT The rapid expansion of multilingual digital platforms has made the accurate analysis of user‐generated content across different languages and cultural contexts increasingly essential. However, existing methods struggle to maintain consistent performance due to linguistic diversity, morphological complexity, and structural variations in text ...

Integer ambiguity validation through machine learning for precise point positioning

Satellite Navigation
The discrimination test of ambiguity resolution, also known as ambiguity validation, is a vital procedure to quantify the reliability of Global Navigation Satellite System (GNSS) ambiguity-fixed solutions. Several well-known tests, including the R-ratio,

Deciphering nodal burden in thyroid carcinoma: A dedicated survey of age, lymph node ratio, log odds of positive nodes, and preoperative prediction models

Journal of Intelligent Medicine, Volume 3, Issue 2, Page 169-191, June 2026.
Abstract Evidence regarding the prognosis of thyroid carcinoma is heterogeneous, ranging from age effects and nodal burden metrics, such as lymph node ratio (LNR) and log odds of positive nodes (LODDS), to preoperative imaging models comprising ultrasound, CEUS, and radiomics.

Effect of phase centre variation on tropospheric delay in PPP‐AR with low‐cost global navigation satellite systems receiver and antenna

IET Radar, Sonar & Navigation
As low‐cost global navigation satellite systems receiver and antenna become increasingly prevalent for water vapour monitoring, precise millimetre‐level characterisation of instrument biases is crucial for maintaining measurement accuracy and reliability.

Simplifying species‐interaction models by grouping parameters: optimal groupings differ between effects and responses

Oikos, Volume 2026, Issue 6, June 2026.
Most ecological models of species interactions require many parameters, making them expensive to fit to experimental or observational data. To reduce the number of parameters, species are often divided into groups a priori, for example on the basis of functional or phylogenetic similarity, and species within these groups are assumed to behave ...

Large Language Models for Explainable Medical Text Summarization: A Systematic Literature Review

WIREs Data Mining and Knowledge Discovery, Volume 16, Issue 2, June 2026.
The graphical abstract highlights the three key aspects addressed in this review: the technical background of medical text summarization methods relevant to clinical decision support; the LLM background in providing context for its diagnosis and clinical significance; and clinical decision support with summarization and explainability in patient care ...

Inferring Internal Structures of Porous Media From Orthogonal External Surfaces: A Novel 2D‐to‐3D Reconstruction Method Based on a Deep Conditional Diffusion Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Diffusion models, a class of generative models renowned for producing realistic images, hold significant promise for reconstructing complex three‐dimensional (3D) porous media. Nevertheless, existing approaches predominantly generate stochastic microstructures visually resembling the training data but often struggle to accurately recover ...
