This paper proposes a broadband metamaterial aperture antenna (BMAA) with a large capacity, low correlation coefficients and high radiation efficiency for coincidence imaging in the terahertz band.The BMAA consists of a random modulated metamaterial aperture and a stripline structure as the feed system.Firstly, a metamaterial element complementary
The purpose of the study was to calibrate and commission optically-stimulated luminescence dosimeters (OSLDs) for in vivo measurements in contact-based 192Ir treatments for superficial high dose rate (HDR) brachytherapy in place of metal-oxide-semiconductor field-effect transistors (MOSFETs).Dose linearity and dose rate dependence were tested by va
Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species.Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and efficient defence used by host species.Egg-recognition experiments have advanced our knowledge of the
