Spacetime deformation effect on the early universe and the PTOLEMY experiment
Published 2017-09-01“…This entails the maximal scale of noncommutativity as well, being of order of 10−4MPl, above which there is no impact whatsoever on the capture rates at PTOLEMY. The latter represents an exceptional upper bound on the scale of noncommutativity coming from phenomenology.…”

Inferring type and scale of noncommutativity from the PTOLEMY experiment
Published 2018-07-01“…Abstract If neutrinos are Dirac particles and their right-handed components can be copiously produced in the early universe, then they could influence a direct observation of the cosmic neutrino background, which, most likely, will come about with the recently proposed PTOLEMY experiment. For coupling of photons to the right-handed neutrinos we use a state-of-the-art version of gauge field theory deformed by the spacetime noncommutativity, to disclose by it not only the decoupling temperature for the said neutrino component, but also the otherwise hidden coupling temperature. …”

Published 2014-11-01“…The epigram in praise of mathematics, attributed to Claudius Ptolemy in the <em>Anth.Gr.</em>, can be shown by the manuscripts and by its variant readings to have originated as a marginalium added to his <em>Syntaxis</em> and later taken to be his own composition.…”

Learning to automate cryo-electron microscopy data collection with Ptolemy
Published 2023-01-01“…However, the development of fully automated targeting algorithms is non-trivial, because images often have low signal-to-noise ratios and optimal targeting strategies depend on a range of experimental parameters and macromolecule behaviors that vary between projects and collection sessions. To address this, Ptolemy provides a pipeline to automate low- and medium-magnification targeting using a suite of purpose-built computer vision and machine-learning algorithms, including mixture models, convolutional neural networks and U-Nets. …”
