MCNP and GADRAS Comparisons

, 2016
To facilitate the timely execution of System Threat Reviews (STRs) for DNDO, and also to develop a methodology for performing STRs, LANL performed comparisons of several radiation transport codes (MCNP, GADRAS, and Gamma-Designer) that have been previously utilized to compute radiation signatures.

Enhancing Specificity, Precision, Accessibility, Flexibility, and Safety to Overcome Traditional CRISPR/Cas Editing Challenges and Shape Future Innovations

Advanced Science, Volume 12, Issue 28, July 24, 2025.
CRISPR/Cas9, while transformative, faces challenges in specificity, precision, delivery, accessibility, flexibility, and safety. This review addresses these limitations by highlighting strategies to reduce off‐target effects, exploring HDR‐based and alternative editing approaches, and evaluating advanced delivery mechanisms.

Despite Potential Risks African Elephants Do Not Always Avoid Mountaineering

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Recent studies have suggested that African elephants (Loxodonta africana) avoid steep slopes (e.g., > 15°) due to energetic costs of movement and the greater risk of falls and tumbles. Yet, using 8.5 years of positional data, we found that elephants in the Ithala Game Reserve, South Africa primarily used slopes < 30° (95% of the locations), while 67 ...

MOCUP: MCNP-ORIGEN2 coupled utility program [PDF]

, 1995
MOCUP is a system of external processors that allow for a limited treatment of the temporal composition of the user-selected MCNP cells in a time-dependent flux environment. The ORIGEN2 code computes the time-dependent compositions of these individually selected MCNP cells.

Delta-ray Production in MCNP 6.2.0

Physics Procedia, 2017
Abstract Secondary electrons in the form of delta-rays, also referred to as knock-on electrons, have been a feature of MCNP for electron and positron transport for over 20 years. While MCNP6 now includes transport for a suite of heavy-ions and charged particles from its integration with MCNPX, the production of delta-rays was still limited to ...
