Well-Posed Initial-Boundary Value Problem for a Constrained Evolution System and Radiation-Controlling Constraint-Preserving Boundary Conditions [PDF]

open access: yes, 2006
A well-posed initial-boundary value problem is formulated for the model problem of the vector wave equation subject to the divergence-free constraint.

Optimizing radiation therapy treatments by exploring tumour ecosystem dynamics in-silico [PDF]

open access: yes, 2019
In this contribution, we propose a system-level compartmental population dynamics model of tumour cells that interact with the patient (innate) immune system under the impact of radiation therapy (RT).

Low radiation dose in computed tomography: the role of iodine [PDF]

open access: yes, 2017
Recent approaches to reducing radiation exposure during CT examinations typically utilize automated dose modulation strategies on the basis of lower tube voltage combined with iterative reconstruction and other dose-saving techniques.

Motion-induced radiation from electrons moving in Maxwell's fish-eye [PDF]

open access: yes, 2013
In \u{C}erenkov radiation and transition radiation, evanescent wave from motion of charged particles transfers into radiation coherently. However, such dissipative motion-induced radiations require particles to move faster than light in medium or to ...

Exotic radiation from a photonic crystal excited by an ultra-relativistic electron beam [PDF]

open access: yes, 2006
We report the observation of an exotic radiation (unconventional Smith-Purcell radiation) from a one-dimensional photonic crystal. The physical origin of the exotic radiation is direct excitation of the photonic bands by an ultra-relativistic electron ...

Interaction between gravitational radiation and electromagnetic radiation [PDF]

open access: yes, 2018
In this review paper we investigate the connection between gravity and electromagnetism from Faraday to the present day. The particular focus is on the connection between gravitational and electromagnetic radiation.

Estimation of surface longwave radiation components from ground-based historical net radiation and weather data [PDF]

open access: yes, 2008
A methodology for estimating ground upwelling, clear-sky and cloud downwelling longwave radiations (L↑, Lsky ↓, and Lcld↓) and net shortwave radiation (Sn) at 30-min temporal scales based on long-term ground-based net radiations and meteorological ...

Unveiling Magnetic Dipole Radiation in Phase-Reversal Leaky-Wave Antennas [PDF]

open access: yes, 2013
The radiation principle of travelling-wave type phase-reversal antennas is explained in details, unveiling the presence of magnetic-dipole radiation in addition to well-known electric dipole radiation.

Radiation Risks and Mitigation in Electronic Systems [PDF]

open access: yes, 2016
Electrical and electronic systems can be disturbed by radiation-induced effects. In some cases, radiation-induced effects are of a low probability and can be ignored; however, radiation effects must be considered when designing systems that have a high ...
