Channel estimation is one of the main challenges for reconfigurable intelligent surface (RIS) assisted communication systems with passive reflective elements due to the high number of parameters to estimate.In this paper, we consider channel estimation for a MIMO FD RIS-assisted wireless communication system and use tensor (multidimensional array)
Outdoor large-scale cultural sites are mostly sensitive to environmental, natural and human made factors, implying an imminent need for a spatio-temporal assessment to identify regions of potential cultural interest (material degradation, structuring, conservation).On the other hand, in Cultural Heritage research quite different actors are involved
Mexican conifer and oak forests are very diverse, and represent the vegetation type with the highest timber production in Mexico.Yet, there is little knowledge about the relationship of forest recovery and MAKITA tree diversity in this type of vegetation.In this study, we analyzed the dynamics of vegetation patches over three time periods covering
Abstract Mitogenomes are essential due to their contribution to cell respiration.Recently they have also been implicated in fungal pathogenicity mechanisms.Members of the basidiomycetous yeast genus Malassezia are an important fungal component of the human skin microbiome, linked to various skin diseases, bloodstream Mattresses infections, and they
