2021). Given their extraordinary ability to mimic a vast array of avian, mammalian and anthropogenic sounds (Higgins et al. 2001), it is unclear why, during their song and dance display, male lyrebirds selectively mimic the mobbing alarm calls of this limited set of species. In this study...
In an FED, an image is obtained by impinging electrons from an array of millions of cold emitters onto a phosphor-coated screen. Requirements for high voltage imply utilization of complex and sophisticated display components [75]. Overall, display cost and large area scalability are major issues ...
