Joint Analysis With Swarm and Ground Stations: Ionospheric Current System and Geomagnetically Induced Currents

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Sudden changes in the ground magnetic field, driven by geomagnetic activity, can ultimately generate geomagnetically induced currents (GICs), which can have a significant impact on artificial technology systems. High rates of change in the horizontal geomagnetic field (dH/dt) can be used as a substitute for the strength of GICs.

High‐Precision Prediction of Auroral Substorm Expansion Phase Evolution Using a Spatio‐Temporal Attention Deep Learning Model

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Auroral substorms are a key manifestation of solar‐terrestrial interactions and the release of energy within the Earth's magnetosphere. The expansion phase, which is characterized by rapid changes in auroral morphology and intensity, poses significant space weather risks to satellite operations and communication systems.

The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid

Space Weather, Volume 24, Issue 2, February 2026.
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

Do Pre‐Clinical Summative Assessments Predict a Student's Clinical Performance? A Retrospective Study

European Journal of Dental Education, Volume 30, Issue 1, Page 117-125, February 2026.
ABSTRACT Introduction Dental students are deemed fit to treat patients (clinical readiness) based on their performance in pre‐clinical summative assessments. This involves assessing knowledge (theory exams) and technical skills (simulation‐based activities).

Cytotoxicity of ammonia‐ and water‐based silver fluoride treatments

European Journal of Oral Sciences, Volume 134, Issue 1, February 2026.
Abstract This study aims to investigate the trans‐dentinal and direct cell viability of ammonia‐ and water‐based silver fluoride treatments. Deep dentin discs were prepared, balanced for permeability and autoclaved. Three‐dimensional cultures of odontoblast‐like cells were transferred to the pulpal aspect of the dentin slices inside perfusion split ...

Optimising Image Feature Extraction and Selection: A Comprehensive Review With Spark Case Studies

Expert Systems, Volume 43, Issue 2, February 2026.
ABSTRACT As benchmark image datasets expand in sample size and feature complexity, the challenge of managing increased dimensionality becomes apparent. Contrary to the expectation that more features equate to enhanced information and improved outcomes, the curse of dimensionality often hampers performance.
