Multispectral Properties of Rocks in Marker Band Valley and Evidence for an Alteration Unit Below the Amapari Marker Band at Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 130, Issue 4, April 2025.
Abstract The Mars Science Laboratory rover, Curiosity, has been examining strata from a period of Martian history where extensive clay mineral formation transitioned to sulfate mineral formation. This mineralogic change corresponds to a change from a wetter to a more arid climate.

Segmentation of RDX and TNT in X‐Ray Computed Tomography Reconstructions of Melt‐Cast Explosives

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 2, February 2025.
Flow chart outlining our process for x‐ray CT data segmentation and quantitative anlayses of explosive microstructures. ABSTRACT Three‐dimensional mesoscale characterization of heterogeneous melt‐cast high explosives is challenging because of the difficulty differentiating binder from explosive crystals: two functionally different materials which are ...

Optimizing Radiation Shielding for Fusion Maintenance Facilities: Insights From a Comprehensive Analysis of ITER Hot Cell

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
One of the primary goals of the ITER project is to demonstrate the safety characteristics of a fusion device, particularly in terms of radiation management. Radiation protection during maintenance periods is of special concern, as personnel performing maintenance‐like activities will be exposed to delayed gamma fields from numerous and complex ...

Verficiation and Validation of Unstructured Meshing Capabilities in MCNP6 [PDF]

, 2022
Discrepancies were found between the legacy CSGs and the new UMs with the latter\u27s introduction in MCNP6. As such, V&V of UMs in MCNP must be conducted to assist in their further development and increase user confidence in them.

Verification and Validation of Monte Carlo n-Particle Code 6 (MCNP6) with Neutron protection Factor Measurements of an Iron Box [PDF]

, 2014
Using a 1984 benchmark experiment, MCNP6 replicated the neutron flux and neutron protection factor (NPF) measurements of an iron box, which simulated a basic military vehicle, resulting in less than 5% difference from the published results. Additionally,
