Discrete symmetries tested at 10 precision using linear polarization of photons from positronium annihilations
PaweÅ Moskal, Eryk CzerwiÅski, Juhi Raj +38
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…
First-in-human quantum entanglement imaging
Pawel Moskal, Deepak Kumar, Sushil Sharma +37
Annihilation photons are quantum-entangled in polarization, a phenomenon that has not been exploited in medical diagnostics so far. We present the first in vivo imaging of the degr…
A Conjugate Bayesian Framework for Fast 3D Positronium Lifetime Estimation with a Partial System Matrix
Berkin Uluutku, Giulianno Gasparato, Manish Das +7
Background: Positronium lifetime imaging extends conventional positron emission tomography by using the time interval between positron emission and annihilation as an additional co…
First Positronium Lifetime Imaging using Mn and Co with a plastic-based PET scanner
Manish Das, Sushil Sharma, Ermias Yitayew Beyene +45
Positronium Lifetime Imaging (PLI) extends positron emission tomography by using the lifetime of positronium atoms as a probe of tissue molecular architecture. In this work, we rep…
HAViT: Historical Attention Vision Transformer
Swarnendu Banik, Manish Das, Shiv Ram Dubey +1
Vision Transformers have excelled in computer vision but their attention mechanisms operate independently across layers, limiting information flow and feature learning. We propose…
Positronium Imaging: History, Current Status, and Future Perspectives
PaweÅ Moskal, Aleksander Bilewicz, Manish Das +11
Positronium imaging was recently proposed to image the properties of positronium atoms in the patient body. Positronium properties depend on the size of intramolecular voids and ox…
