Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Palliative radiotherapy comprises a significant portion of the radiation treatment workload. Volumetric‐modulated arc therapy (VMAT) improves dose conformity and, in conjunction with flattening filter free (FFF) delivery, can decrease treatment times, both of which are desirable in a population with a high probability of retreatment ...

ASPECTS REGARDING LIQUID DIELECTRIC DISCHARGES USED IN ELECTRIC EROSION PROCESSES
Nonconventional Technologies Review, 2020 This scientific paper purpose is the problem of the chain of atomic, quantum and wavy phenomena that ends in creating the conditions for the appearance of a strictly local path, which is electrically conductive, through the liquid dielectric that washes

Time reversal of arbitrary photonic temporal modes via nonlinear optical frequency conversion
New Journal of Physics, 2018 Single-photon wave packets can carry quantum information between nodes of a quantum network. An important general operation in photon-based quantum information systems is ‘blind’ reversal of a photon’s temporal wave packet envelope, that is, the ability ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background To assess the dose‐sparing capabilities of a yaw‐limited volumetric modulated arc therapy (YL_VMAT) beam setup for adjacent organs at risk (OAR) in comparison with 3D‐conventional radiation therapy (3D‐CRT), intensity‐modulated radiation therapy (IMRT) and conventional VMAT for radiation therapy in left‐sided breast cancer patients.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose The dual‐layer multileaf collimator (MLC) in Halcyon adds complexities to the dose calculation process owing to the variability of dosimetric characteristics with leaf motion. Recently, an enhanced leaf model (ELM) was developed to refine the MLC model in the Eclipse treatment planning system. This study investigates the performance of

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.

Proca Electrodynamics Approach to The Massive Photon [PDF]
مجلة التربية والعلمThe work presents a reflection on the importance of the existence of a massive photon. The discussion takes place based on the development of Maxwell's electrodynamics, introducing the massive term for the photon through Proca's electrodynamics.
