  • Patent number: 11920168
    Abstract: The disclosure in some aspects relates to recombinant adeno-associated viruses having nuclease grafted to one or more capsid proteins. In some aspects, the disclosure relates to isolated AA V capsid proteins having terminally grafted nucleases and isolated nucleic acids encoding the same. Recent approaches to delivering nucleases to cells for gene editing have focused on delivering of expression vectors engineered to express the nucleases in target cells. However, these approaches have proved to be problematic in many instances due to genotoxicity resulting from to prolonged expression of gene editing system in vivo. To prevent such off-target genotoxicity due to prolonged presence of a gene editing system, several studies explored delivery of mRNA or protein instead of delivering the gene coding for the nucleases in cell culture.

  • Patent number: 11921229
    Abstract: An apparatus, including processing unit (PU) cores and computer readable storage devices storing machine instructions for determining a distance between a target object and a radar sensor circuit. The PU cores receive a beat signal generated by the radar sensor circuit and compensate for a phase difference between the received beat signal and a reconstruction of the received beat signal to obtain a phase compensated beat signal. The phase compensated beat signal is then filtered to remove spurious reflections by demodulating the phase compensated beat signal using an estimated frequency of the phase compensated beat signal. The PU cores then apply a low pass filter to the demodulated phase compensated beat signal, resulting in a modified beat signal. The PU cores then determine the distance between the target object and the radar sensor circuit using the modified beat signal.

  • Patent number: 11873265
    Abstract: Disclosed is a method for preparing a benzyl amine compound, i.e., synthesizing a benzyl amine compound by means of an oxidation reaction between a methylbenzene/ethylbenzene compound and arylamine by using an ionic iron (III) complex containing 1,3-di-tert-butylimidazolium cation and having a molecular formula of [(RNCHCHNR)CH][FeBr4] (R being tert-butyl) and di-t-butyl peroxide as an oxidant. The present invention is not only applicable to a methylbenzene compound containing a benzylic primary carbon-hydrogen bond but also applicable to an ethylbenzene compound containing a benzylic secondary carbon-hydrogen bond, and therefore is widely applicable. This is the first case where the preparation of a benzyl amine compound by means of an oxidation reaction between a methylbenzene/ethylbenzene compound and arylamine is implemented by an iron catalyst.
