Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Numerical Thermal‐Hydraulic Evaluation of an Integrated Direct‐Indirect Oil Cooling System for an Electric Motor Under Steady‐State Overload Conditions

Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.
This study evaluates an integrated direct‐indirect oil cooling system for electric motor thermal management under steady‐state overload conditions. The results show that the combined cooling architecture improves heat removal from the winding, stator, and housing while balancing pressure drop penalties.

Magnetic Fabric: A Geophysical Approach for Identifying China's Neolithic Rammed Earth

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Accurate identification of rammed‐earth remains is essential for understanding early social complexity in Neolithic China. However, scientific methods for identifying rammed‐earth materials in Chinese prehistoric archeology remain limited, and identification still rely largely on field observations.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.
