Abstract: An angle of arrival estimation method and device, where a first device: collects a first signal from a second device using a reference antenna and a first antenna group; determines first channel state information (CSI); collects a second signal from the second device using the reference antenna and a second antenna group; determines second CSI; determines a phase difference vector between the first signal and the second signal based on a vector corresponding to the reference antenna in the first CSI and a vector corresponding to the reference antenna in the second CSI; compensates for the second CSI using the phase difference vector; and estimates an angle of arrival of the second device based on the first CSI and compensated second CSI.

Abstract: Squaraine dyes are used to detect the presence of protein in a test sample, which is a substance that may contain protein. A squarine dye is placed in water, and in some instances joined with an aggregation agent, to create an aqueous dye solution. That dye solution is joined with a test sample. When the dye solution is joined with the test sample and the resultant test solution is excited by the application of photons, a resulting fluorescence or absence thereof reveals if protein was present in the test sample.

Abstract: 2,5-Bis(benzoxazol-2?-yl)benzene-1,4-diol derivatives (Zinhbo derivatives) are used to detect zinc ions and have particular application in vivo and in vitro. Zinhbo derivatives upon excitation give a florescence response emission that can be used to determine the presence of zinc cation in solution. Zinhbo derivatives complexed with zinc cations upon excitation can produce a florescence response emission in the visible and near infrared range. Zinhbo derivatives complexed with zinc cations exhibit a large stoke shift between the excitation and emission wavelengths.
