Journal of High Energy Physics, 2020 Abstract We discuss radiation in theories with scalar fields. Our key observation is that even in flat spacetime, the radiative fields depend qualitatively on the coupling of the scalar field to the Ricci scalar: for non-minimally coupled scalars, the radiative energy density is not positive definite, the radiated power is not ...

Harnessing Radiation Biology to Augment Immunotherapy for Glioblastoma
Frontiers in Oncology, 2019 Glioblastoma is the most common adult primary brain tumor and carries a dismal prognosis. Radiation is a standard first-line therapy, typically deployed following maximal safe surgical debulking, when possible, in combination with cytotoxic chemotherapy.

Replica wormholes and the entropy of Hawking radiation [PDF]
Journal of High Energy Physics, 2019 The information paradox can be realized in anti-de Sitter spacetime joined to a Minkowski region. In this setting, we show that the large discrepancy between the von Neumann entropy as calculated by Hawking and the requirements of unitarity is fixed by ...

THE PENETRATING RADIATION [PDF]
Science, 1907 The announcement of the discovery of the penetrating radiation was made simultaneously by Rutherford and Cooke and McClennan and Burton in 1902. Investigations on radioactive substances had shown that some of these emit a very penetrating radiation, the γ radiation, resembling hard X‐rays.
