MCNP and GADRAS Comparisons

open access: yes, 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.

Safety, efficacy, pharmacokinetics, and mechanisms of novel 10B‐boronophenylalanine combined with a radio‐frequency quadrupole accelerator in boron neutron capture therapy: A preclinical study in head and neck squamous cell carcinoma

open access: yesPrecision Radiation Oncology, Volume 10, Issue 3, Page 333-346, September 2026.
This study demonstrates that the novel 10B‐BPA‐based BNCT system, combined with an RFQ accelerator, effectively targets head and neck squamous cell carcinoma. It induces tumor regression safely and efficiently by triggering DNA damage and activating the ROS/HIF‐1α/NF‐κB pathway, leading to caspase‐3‐mediated apoptosis.

Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

Study of prompt gamma and neutron emission for real‐time range verification in proton and carbon‐ion therapy

open access: yesMedical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...
