Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

Advanced Engineering Materials, EarlyView.Herein the metal‐to‐insulator transition is investigated when depositing vanadium dioxide (VO2) on glass or aluminum‐doped zinc oxide (AZO). O2 flow tuning during the deposition and additional post annealing are effective to control the metal‐to‐insulator transition. However, the VO2/AZO/glass stack reveals an increase in the transition temperature and

Effects of spin-orbit coupling on the optical response of a material [PDF]
Phys. Rev. B 98, 245410 (2018), 2018 We investigate the effects of spin-orbit coupling on the optical response of materials. In particular, we study the effects of the commutator between the spin-orbit coupling part of the potential and the position operator on the optical matrix elements.

Active Hydrogen for Electrochemical Ammonia Synthesis
Advanced Functional Materials, EarlyView.This review provides a comprehensive overview of the active hydrogen (H*) for electrochemical ammonia synthesis with particular attention given to the regulation of H* generation and consumption to suppress the competition of hydrogen evolution reaction and enhance the yield, selectivity, and Faradaic efficiency of ammonia.

Orbits for sixteen binaries [PDF]
Serbian Astronomical Journal, 2006 In this paper orbits for 13 binaries are recalculated and presented. The reason is that recent observations show higher residuals than the corresponding ephemerides calculated by using the orbital elements given in the Sixth Catalog of Orbits of Visual ...

Tidal and rotational effects in the perturbations of hierarchical triple stellar systems. II. Eccentric systems - the case of AS Camelopardalis [PDF]
, 2007 We study the perturbations of a relatively close third star on a tidally distorted eccentric eclipsing binary. We consider both the observational consequences of the variations of the orbital elements and the interactions of the stellar rotation with the

The Orbital Elements of R Aquarii [PDF]
The Astronomical Journal, 2007 Radial velocity information has been collected on R Aquarii since 1946. Various stellar radiating systems have been used to determine the velocity centroid of the long-period variable. These velocity values have been combined and analyzed in an attempt to extract the orbital parameters of the binary star system.

Orbital Elements Evolution Due to a Perturbing Body in an Inclined Elliptical Orbit
, 2014 Kozai developed the secular and long period terms of the disturbing function due to lunisolar perturbations in terms of the orbital elements of a satellite, the Sun and the Moon, and applied those secular perturbations to asteroids with high inclination ...
