Abstract Background Childhood obesity and physical inactivity are increasing dramatically worldwide.Children of low socioeconomic status and/or children of migrant background are especially at risk.In general, the overall effectiveness of school-based programs on health-related outcomes has been disappointing.A special gap exists for younger childr

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 nacrack.com structure as the feed system.Firstly, a metamaterial element co
