Cancers, 2015 In addition to the physical advantages (Bragg peak), the use of charged particles in cancer therapy can be associated with distinct biological effects compared to X-rays. While heavy ions (densely ionizing radiation) are known to have an energy- and charge-dependent increased Relative Biological Effectiveness (RBE), protons should not be very ...

Proton Sensing on the Ocular Surface: Implications in Eye Pain
Frontiers in Pharmacology, 2021 Protons reaching the eyeball from exogenous acidic substances or released from damaged cells during inflammation, immune cells, after tissue injury or during chronic ophthalmic conditions, activate or modulate ion channels present in sensory nerve fibers

The Proton-Proton Interaction [PDF]
Physical Review, 1950 This paper presents a phenomenological analysis of the proton-proton scattering observed at 32 and 340 Mev in terms of static nuclear potentials. Comparison of these results with the neutron-proton scattering at 40, 90, and 280 Mev analyzed previously indicates that nuclear forces are not charge independent. In particular, there is definite evidence in

Nuclear Physics B, 1967 Abstract We calculate proton-proton Bremsstrahlung cross sections using the Tabakin separable potentials to generate off-shell nucleon-nucleon t-matrix elements in low partial waves and off-shell one-pion-exchange amplitudes for the higher partial waves.

Study on the spectrum of the injected relativistic protons [PDF]
, 2008 About 10TeV gamma-ray emission within 10 pc region from the Galactic Center had been reported by 4 independent groups. Considering that this TeV gamma-ray emission is produced via a hadronic model, and the relativistic protons came from the tidal ...

Collective neutrino-pair emission due to Cooper pairing of protons in superconducting neutron stars [PDF]
, 2000 The neutrino emission due to formation and breaking of Cooper pairs of protons in superconducting cores of neutron stars is considered with taking into account the electromagnetic coupling of protons to ambient electrons.

Comparison of Geant4 hadron generation with data from the interactions with beryllium nuclei of +8.9 GeV/c protons and pions, and of -8 GeV/c pions [PDF]
, 2008 Hadron generation in the Geant4 simulation tool kit is compared with inclusive spectra of secondary protons and pions from the interactions with beryllium nuclei of +8.9 GeV/c protons and pions, and of -8.0 GeV/c pions. The data were taken in 2002 at the

Enantioselective protonation [PDF]
Nature Chemistry, 2009 Enantioselective protonation is a common process in biosynthetic sequences. The decarboxylase and esterase enzymes that effect this valuable transformation are able to control both the steric environment around the proton acceptor (typically an enolate) and the proton donor (typically a thiol).
