Impact of Uncertain Parameters on Navier–Stokes Equations With Heat Transfer via Polynomial Chaos Expansion

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.
This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Hydrodynamical Simulations of Proton Ingestion Flashes in Type I X-Ray Bursts

The Astrophysical Journal
We perform the first multidimensional fluid simulations of thermonuclear helium ignition underneath a hydrogen-rich shell. This situation is relevant to Type I X-ray bursts on neutron stars that accrete from a hydrogen-rich companion.

Identity Play: Middle School Youths' Provisional Self‐Making in Horizon‐Expanding STEM Spaces

Science Education, Volume 110, Issue 3, Page 780-802, May 2026.
ABSTRACT This study introduces identity play as an analytic construct for science education to explore improvisational dimensions of middle school students' STEM identity development in multiple out‐of‐school learning experiences focused on environmental problem‐solving.

Machine Learning Characterization of Intermittency in Relativistic Pair Plasma Turbulence: Single and Double Sheet Structures

The Astrophysical Journal Letters
The physics of turbulence in magnetized plasmas remains an unresolved problem. The most poorly understood aspect is intermittency—spatiotemporal fluctuations superimposed on the self-similar turbulent motions.

Seafloor Sediments, Morphologic Features, and Geotechnical Properties of Harrison Bay in the Alaskan Beaufort Sea

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Sediments on Arctic continental shelves are impacted by sea ice and ice‐related processes for up to 9 months per year. As a result, seabed morphology in cold regions can exhibit features such as ice scours which are absent on lower‐latitude shelves.

Post‐Acquisition Image‐Based Localization for High Resolution Thermal and Visible/Shortwave Infrared Images With Application to the Lunar Trailblazer Mission

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract The Lunar Trailblazer mission aimed to assess the presence of water on the lunar surface using imaging spectroscopy in visible shortwave infrared (VSWIR) coupled with high‐resolution multispectral imaging in thermal midwave‐infrared (MWIR), captured simultaneously over the same target from orbit around the Moon with two different instruments ...

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.
