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.

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

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.

Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor II [PDF]
, 2012 The Advanced CCD Imaging Spectrometer is an instrument on the Chandra X-ray Observatory. CCDs are vulnerable to radiation damage, particularly by soft protons in the radiation belts and solar storms. The Chandra team has implemented procedures to protect ACIS during high-radiation events including autonomous protection triggered by an on-board ...

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 ...
