Development of a low‐cost 3D‐printed phantom for end‐to‐end testing of model‐based dose calculation algorithms (MBDCAs) in high‐dose‐rate (HDR) brachytherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Model‐Based Dose Calculation Algorithms (MBDCAs), such as AcurosBV, have improved dosimetric accuracy in high‐dose‐rate (HDR) brachytherapy by accounting for medium heterogeneities and variations in scatter conditions. However, their safe and effective clinical implementation requires thorough commissioning, of which end‐to‐end (E2E)

The GPSP Atlas: High-resolution Galactic Photon Survival Probability Atlas for Very-high- and Ultra-high-energy Gamma-Ray Astronomy

The Astrophysical Journal
The emergence of Galactic PeV astronomy makes photon–photon ( γγ ) absorption an increasingly important component of gamma-ray data analysis. In this work, the Galactic Photon Survival Probability (GPSP) atlas is presented as the first Galactic framework

Ground-based gamma-ray astronomy [PDF]

AIP Conference Proceedings, 2000
Ground-based gamma-ray astronomy has become an active astrophysical discipline with four confirmed sources of TeV gamma rays, two plerionic supernova remnants (SNRs) and two BL Lac objects (BL Lacs). An additional nine objects (one plerion, three shell-type SNRs, one X-ray binary, and four BL Lacs) have been detected but have not been confirmed by ...

Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025

Space Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.

Timing Analysis of Bright Pulsars with Nine Years of DAMPE Data

Particles
Based on nine years of flight data from the DArk Matter Particle Explorer (DAMPE) and a novel gamma-ray selection algorithm developed in previous work, we recalculate the instrument response functions (IRFs) in the 1–104 GeV energy range.
