  • Publication number: 20240200038
    Abstract: The present disclosure relates to the technical field of separation and purification of virus-like particles (VLPs), in particular to a method for separating and purifying influenza VLPs using an aqueous two-phase system (ATPS). In the method for separating and purifying influenza VLPs by an ATPS of the present disclosure, a phosphate buffer as a phase-forming salt is mixed with PEG400 to form an aqueous two phase-based extraction system to extract the influenza VLPs. Compared with the prior art, the method for separating and purifying the influenza VLPs has a simple process, which only requires allowing to stand and centrifugation to form an aqueous two phase; and liquids in upper and lower phases can be recycled and reused. The method shows a low cost and environmental friendliness. The extracted influenza VLPs have desirable purity, and a structure and an activity of the influenza VLPs are maintained.

  • Patent number: 12007472
    Abstract: A digital direct line-of-sight (DLOS) intermediate frequency (IF) signal of a DLOS component of an RF carrier signal transmitted by a transmitter located above the surface of the earth and a digital reflected IF signal of a reflected component of the carrier signal that is reflected from a specular point (SP) on the surface of the earth are received. Modeled reference signal parameters are generated using the digital DLOS IF signal and known locations of one or more receiving antennas, the transmitter, and the SP. A reference signal is generated based on the modeled reference signal parameters and feedback of a previously estimated ??. The reference signal is correlated with the digital reflected IF signal to produce in-phase (I) and quadrature-phase (Q) correlation results. An estimated C/N0 and an estimated ?? for the digital reflected IF signal are calculated from the correlation results.
