Radiation mitigation of the intestinal acute radiation injury in mice by 1‐[(4‐nitrophenyl)sulfonyl]‐4‐phenylpiperazine

open access: yesStem Cells Translational Medicine, 2020
The objective of the study was to identify the mechanism of action for a radiation mitigator of the gastrointestinal (GI) acute radiation syndrome (ARS), identified in an unbiased high‐throughput screen.

The Page curve of Hawking radiation from semiclassical geometry [PDF]

open access: yesJournal of High Energy Physics, 2019
We consider a gravity theory coupled to matter, where the matter has a higher-dimensional holographic dual. In such a theory, finding quantum extremal surfaces becomes equivalent to finding the RT/HRT surfaces in the higher-dimensional theory. Using this

Squamous Cell Carcinoma of Cervix with Isolated Metastasis to Ethmoidal Sinus: A Rare Occurrence [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Squamous Cell Carcinoma (SCC) of the cervix is a highly prevalent malignancy. Its spread and metastasis is mostly loco-regional. The occurrence of distant extra-pelvic metastases is exceedingly rare, particularly with the involvement of paranasal sinus.

Replica wormholes and the entropy of Hawking radiation [PDF]

open access: yesJournal 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 ...

Outcomes of adjunctive radiation therapy for the treatment of mast cell tumors in dogs and assessment of toxicity: A multicenter observational study of 300 dogs

open access: yesJournal of Veterinary Internal Medicine, 2021
Background Radiation therapy is commonly used as an adjunct to incomplete surgical excision in dogs with mast cell tumors (MCT), but the optimal dose and fractionation regimen have yet to be determined.

The Blackbody Radiation Spectrum Follows from Zero-Point Radiation and the Structure of Relativistic Spacetime in Classical Physics [PDF]

open access: yesFoundations of Physics 42, 595-614 (2012), 2011
The analysis of this article is entirely within classical physics. Any attempt to describe nature within classical physics requires the presence of Lorentz-invariant classical electromagnetic zero-point radiation so as to account for the Casimir forces between parallel conducting plates at low temperatures.

Harnessing Radiation Biology to Augment Immunotherapy for Glioblastoma

open access: yesFrontiers 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.

Serious limitations of the strong equivalence principle [PDF]

open access: yesInternational Journal of Modern Physics A Vol. 32 (2017) 1750068, 2016
It is well known that an accelerated charged particle radiates away energy. However, whether an accelerated neutral composite particle radiates away energy is unclear. We study decoherent Larmor radiation from an accelerated neutral composite object. We find that the neutral object's long wavelength radiation is highly suppressed because radiation from
