In this paper, the statistical analysis of cluster is presented based on the outdoor wideband multiple-input multiple-output (MIMO) channel measurements to facilitate IMT-Advanced system design. Clusters are found in multi-dimensional space, i.e., on the azimuth of arrival-azimuth of departure-elevation of departure-delay domain. We identify clusters with(More)
Novel linear supramolecular polymers, based on the combination of two classical binding interactions: the quadruple hydrogen bonding ureidopyrimidinone units and crown ether-paraquat host-guest recognition motifs, have been constructed from two heteroditopic monomers.
A modified Bouveault-Blanc reduction has been developed for the synthesis of α,α-dideuterio alcohols from carboxylic acid esters. Sodium dispersions are used as the electron donor in this electron transfer reaction, and ethanol-d1 is employed as the deuterium source. This reaction uses stable, cheap, and commercially available reagents, is operationally(More)
