Aliasing is a general problem in the analysis of any measurements that make sampling at discrete points.Sampling in the spatial domain results in a periodic pattern of spectra in the wave vector domain.This effect is called spatial aliasing, and it is of particular importance for multi-spacecraft measurements in space.We first present the theoretic
BackgroundThe most primitive ornithischian dinosaurs were small bipeds, but quadrupedality evolved three times independently in the clade.The transition to quadrupedality from bipedal ancestors is rare in the history of terrestrial vertebrate evolution, and extant analogues do not exist.Constraints imposed on quadrupedal ornithischians by their anc
This paper provides a comprehensive survey on the coexistence of cellular and IEEE 802.11 standards from a holistic viewpoint that takes into account the coexistence of all existing and future cellular and IEEE 802.11 standards in all the available unlicensed spectrum bands.Unlike existing survey works focusing mostly on any unlicensed band and/or
