Radar Scheme With Raised Reflector for NLOS Vehicle Detection
(07 / 2022)
articleThe employment of passive reflectors enables the millimeter-wave automotive radars to detect an approaching vehicle in non-line-of-sight conditions. In this paper, the installation of such reflectors above the sidewalk at ... -
Radial structure of OAM-carrying fundamental x-waves
(2021)
articleWe investigate the spectral degree of freedom of OAM-carrying localized waves and its influence on their transverse intensity distribution. In particular, we focus our attention on exponentially decaying spectra, which are ... -
Radially self-accelerating optical pulses
(2019)
articleWe generalize the concept of radially self-accelerating beams to the domain of optical pulses. In particular, we show how radially self-accelerating optical pulses (RSAPs) can be constructed by suitable superpositions of ... -
Radiation dose of the eye lens in CT examinations of the brain in clinical practice : The effect of radiographer training to optimise gantry tilt and scan length
(04 / 2023)
articleLenses are always exposed to radiation in brain computed tomography (CT) scans. However, the lens dose can be reduced by excluding lens from scanning area by optimising gantry tilt and scan length. The object of this study ... -
Radiation effects on phosphate glasses : Review
(17.10.2019)
reviewGlass and its properties are subject to a variety of changes under the influence of high energy radiation. Therefore, radiation-induced defects in glasses requires high attention due to the wide application of glasses in ... -
Radiation-induced accelerated aging of the brain vasculature in young adult survivors of childhood brain tumors
(2020)
articleBackground: Cranial radiotherapy may damage the cerebral vasculature. The aim of this study was to understand the prevalence and risk factors of cerebrovascular disease (CVD) and white matter hyperintensities (WMHs) in ... -
Radiation-induced defects and effects in germanate and tellurite glasses
(31.08.2020)
reviewThis review focuses on the radiation-induced changes in germanate and tellurite glasses. These glasses have been of great interest due to their remarkable potential for photonics, in terms of extended transmission window ... -
