Bound States in the Continuum on Periodic Structures: Perturbation Theory and Robustness [PDF]

Optics Letters, Vol. 42, No. 21, pp. 4490-4493, 2017, 2017
On periodic structures, a bound state in the continuum (BIC) is a standing or propagating Bloch wave with a frequency in the radiation continuum. Some BICs (e.g., antisymmetric standing waves) are symmetry-protected, since they have incompatible symmetry with outgoing waves in the radiation channels.

Personal Radiation Protection and Corresponding Dosimetry in Interventional Radiology: An Overview and Future Developments Persönliche Strahlenschutzmittel und Dosimetrie des medizinischen Personals in der interventionellen Radiologie: Aktueller Status und neue Entwicklungen

RöFo - Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren, 2019
Background The increasing number of minimally invasive fluoroscopy-guided interventions is likely to result in higher radiation exposure for interventional radiologists and medical staff. Not only the number of procedures but also the complexity of these

A comparative study on the dose–effect of low-dose radiation based on microdosimetric analysis and single-cell sequencing technology

Scientific Reports
The biological mechanisms triggered by low-dose exposure still need to be explored in depth. In this study, the potential mechanisms of low-dose radiation when irradiating the BEAS-2B cell lines with a Cs-137 gamma-ray source were investigated through ...

Backreaction of the Hawking radiation [PDF]

Phys.Lett. B638 (2006) 523-525, 2005
Black holes create a vacuum matter charge to protect themselves from the quantum evaporation. A spherically symmetric black hole having initially no matter charges radiates away about 10% of the initial mass and comes to a state in which the vacuum-induced charge equals the remaining mass.

Implications of recent epidemiologic studies for the linear nonthreshold model and radiation protection

Journal of Radiological Protection, 2018
The recently published NCRP Commentary No. 27 evaluated the new information from epidemiologic studies as to their degree of support for applying the linear nonthreshold (LNT) model of carcinogenic effects for radiation protection purposes (NCRP 2018 ...

Dose Variations Using an X-Ray Cabinet to Establish in vitro Dose-Response Curves for Biological Dosimetry Assays

Frontiers in Public Health, 2022
In biological dosimetry, dose-response curves are essential for reliable retrospective dose estimation of individual exposure in case of a radiation accident.

Protection layers on a superconducting microwave resonator toward a hybrid quantum system [PDF]

Journal of Applied Physics 118, 134901 (2015), 2014
We propose a protection scheme of a superconducting microwave resonator to realize a hybrid quantum system, where cold neutral atoms are coupled with a single microwave photon through magnetic dipole interaction at an interface inductor. The evanescent field atom trap such as a waveguide/nanofiber atom trap, brings both surface-scattered photons and ...

Microdosimetry of diagnostic X-rays: applications of the variance-covariance method. [PDF]

, 1992
Microdosimetric measurements in beams of diagnostic X rays (between 30 and 125 kV) have been performed. In these pulsed radiation fields, microdosimetric measurements are possible only by application of the variance-covariance technique.
