In vivo assessment of cancer and precise location of altered tissues at initial stages of
molecular disorders are important diagnostic challenges. Positronium is copiously formed in …

Positronium is abundantly produced within the molecular voids of a patient's body during
positron emission tomography (PET). Its properties dynamically respond to the submolecular …

Discrete symmetries play an important role in particle physics with violation of CP connected
to the matter-antimatter imbalance in the Universe. We report the most precise test of P, T …

The purpose of the presented research is estimation of the performance characteristics of
the economic total-body Jagiellonian-PET system (TB-J-PET) constructed from plastic …

Charged lepton system symmetry under combined charge, parity, and time-reversal
transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic …

Medical healthcare centers are envisioned as a promising paradigm to handle vast data for
