Abstract We present Antenna Flylead realistic models of flavor in SU(5) and SO(10) grand unified theories (GUTs).The models are renormalizable and do not require any exotic representations in order to accommodate the necessary GUT breaking effects in the Yukawa couplings.They are based on a simple clockwork Lagrangian whose structure is enforced wi
Objective: To investigate the potential role of wild birds as fecal spreaders of enteropathogenic, enterohemorrhagic and Shiga-toxins producing Escherichia coli (E.coli), enteropathogenic E.coli, enterohemorrhagic E.coli and Shiga toxin-producing E.coli strains.Methods: Fecal samples collected from 121 wild birds of different orders and species wer
The two main Amplify and Forward cooperative protocols are the orthogonal (OAF) and the nonorthogonal one (NAF).In this paper, we consider a given source, N relays, a destination, and a channel realization and we try to resolve the following problem: what is the best way to communicate: without cooperation or using one of the two cooperative protoc
