We present a new approach for the identification of ultra-high energy cosmic rays from sources using dynamic graph convolutional neural networks. These networks are designed to handle sparsely arranged objects and exploit their short- long-range correlations. Our method searches patterns in arrival directions rays, which expected result coherent deflections magnetic fields. The network discriminates astrophysical scenarios with source signatures those only isotropically distributed allows...
At the highest energies, cosmic rays can be detected only indirectly by extensive air showers they create upon interaction with Earth's atmosphere. While high-statistics measurements of energy and arrival directions performed large surface detector arrays like Pierre Auger Observatory, determination cosmic-ray mass on an event-by-event basis is challenging. Meaningful physical observables in this regard include depth maximum air-shower profiles, which related to mean free path ray atmosphere...
Purpose: This paper aims to determine the effective point of measurement and total perturbation correction p parallel‐plate chambers for clinical photon dosimetry. Methods: The (EPOM) was calculated using EGSnrc Monte Carlo code system with user egs_ chamber. Depth dose curves ionization were in a water phantom several high energy spectra (4, 6, 10, 15, 18 MV‐X). Different normalization criterions (normalization maximum depth curve value 10 cm depth) have been applied. EPOM determined by...
