Untethered robots of the size of a few microns have attracted increasing attention for the potential to transform many aspects of manufacturing, medicine, health care, and bioengineering.Previously impenetrable environments have become available for high-resolution in situ and in vivo manipulations as the size of the untethered robots goes down to
Relaying is one of the useful techniques to enhance wireless physical-layer security.Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this is at the price of sophisticated implementation.As an alternative, two-path successive relaying h
Objective: to consider the possibility of a property tax promoting allocative efficiency without losses to investment efficiency.Methods: dialectical approach to the cognition of social phenomena, enabling to analyze them in their historical development and functioning in the context of a set of objective and subjective factors, which determined th
