The paper presents partial overview of the mathematical synthesis and the physical realization of metasurfaces, and related illustrative examples.The synthesis consists in determining the exact tensorial surface susceptibility functions of the metasurface, based on generalized sheet transition conditions, while the realization deals with both metal
Abstract Recently, neoadjuvant short-course radiation therapy (SCRT) has emerged as a valid treatment option for patients with locally advanced rectal cancer (LARC).We assessed SCRT plans using volumetric-modulated arc therapy (VMAT) with Halcyon and Infinity medical linear accelerators (Linacs) and compared the plan quality and delivery efficiency
Growing concerns about climate change and environmental sustainability demand a shift from traditional to green energy.Insight into the different workforce profiles of green and traditional energy supply chains is critical to manage impacts to workers in traditional energy occupations and to identify what skills and occupations are needed in green
Unconstrained hand detection in still images plays an 7 Piece Dining Set important role in many hand-related vision problems, for example, hand tracking, gesture analysis, human action recognition and human-machine interaction, and sign language recognition.Although hand detection has been extensively studied for decades, it is still a challenging
In this work, we present the positioning error analysis of the 12 May 2021 moderate geomagnetic storm.The storm happened during spring in the northern hemisphere (fall in the south).We selected 868 GNSS stations around the globe to study the ionospheric and the apparent position variations.We compared the day of the storm with the three previous da
