Refocusing of Moving Ships in Squint SAR Images Based on Spectrum Orthogonalization
Remote Sensing, 2021 Moving ship refocusing is challenging because the target motion parameters are unknown. Moreover, moving ships in squint synthetic aperture radar (SAR) images obtained by the back-projection (BP) algorithm usually suffer from geometric deformation and ...

On the infrared behaviour of Gluons and Ghosts in Ghost-Antighost symmetric gauges [PDF]
, 2003 To investigate the possibility of a ghost-antighost condensate the coupled Dyson--Schwinger equations for the gluon and ghost propagators in Yang--Mills theories are derived in general covariant gauges, including ghost-antighost symmetric gauges.

Orbital cellulitis in a neonate of the tooth bud origin : A case report
Indian Journal of Ophthalmology, 2014 Orbital cellulitis is a serious, yet uncommon infection in neonates. It can result in significant sight and life threatening complications. Most commonly, it occurs secondarily as the result of a spread of infection from the sinuses.

Beamforming Codebook Compensation for Beam Squint with Channel Capacity Constraint
, 2017 Analog beamforming with phased arrays is a promising technique for 5G wireless communication in millimeter wave bands. A beam focuses on a small range of angles of arrival or departure and corresponds to a set of fixed phase shifts across frequency due ...

The Spectrum and Variability of Circular Polarization in Sagittarius A* from 1.4 to 15 GHz [PDF]
, 2002 We report here multi-epoch, multi-frequency observations of the circular polarization in Sagittarius A*, the compact radio source in the Galactic Center. Data taken from the VLA archive indicate that the fractional circular polarization at 4.8 GHz was -0.
