Abstract: Disclosed are methods and compositions for use in preparing dynamic biological macromolecules for high-resolution cryo-electron microscopy or cryo-electron tomography imaging. The compositions contain a metallo-supramolecular branched polymer with a positive zeta potential, containing a hydrophilic polymer segment, a chelating chemical group, and a metal ion. The hydrophilic polymer segment is covalently bonded to the chelating chemical group that is in turn bonded to the metal ion via a dative bond. The methods and compositions can be used to improve particle distribution in vitreous ice and/or to change particle orientations in vitreous ice. Accordingly, the methods and compositions can be utilized to improve particle distribution for high resolution structure determination using single-particle cryo-EM.

Abstract: This application provides a signal transmission method and an apparatus, to reduce an envelope ripple of a transmission signal. The method includes: A base station obtains a first bit sequence and maps the first bit sequence to a first modulation symbol sequence, where a value of each modulation symbol in the first modulation symbol sequence belongs to a first constellation point set, the first constellation point set includes K modulation symbols, and each of the K modulation symbols has a different amplitude. The base station sequentially performs a DFT, weighting, and an IFFT on each modulation symbol in the first modulation symbol sequence to obtain a first signal. Based on the foregoing solution, an envelope ripple of the signal generated by the base station in time domain is small. This facilitates demodulation of the transmission signal by a terminal.
