Due to the atmospheric turbulence, the motion trajectory of airborne very high resolution (VHR) synthetic aperture radars (SARs) is inevitably affected, which introduces range-variant range cell migration (RCM) and aperture-dependent azimuth phase error (APE).Both types of errors consequently result in defocused images, as residual range- and apert
The paper investigates the terahertz performance of a mutually injection-locked multi-element high electron mobility avalanche transit time (HEM-ATT) source based on AlGaN/GaN two-dimensional electron gas (2-DEG).Utilizing a nanostrip patch type planar coupling circuit, mutual injection locking between adjacent elements is achieved.The paper provid
The use of agonist therapy in prison is not widespread in Italy or in the rest MAXI CAL of the world.This causes a strong limitation in access to care for inmates, but above all causes serious negative consequences on public health, due to the lack of treatment of a population otherwise difficult to reach.This population, if left untreated, present
