  • Publication number: 20230212574
    Abstract: A self-circularization RNA construct that can be expressed in a DNA vector and simultaneously circularized through a self-targeting and splicing reaction to form a circRNA is disclosed. The circRNA can consist only of a gene of interest which can be a coding, non-coding, or a combination thereof. The gene of interest has the advantage of being able to rapidly express a peptide or protein. The formed circRNA has a circular structure and has a stable and high half-life because 5? and 3? ends are not exposed. Accordingly, functional RNA such as miRNA, anti-miRNA, siRNA, shRNA, aptamer, functional RNA for gene/RNA editing, ADAR (adenosine deaminase acting on the RNA)-recruiting RNA, mRNA vaccine, mRNA therapeutic agent, vaccine adjuvant, and CAR-T mRNA can be produced as a stable circRNA in cells.

  • Publication number: 20210080542
    Abstract: A method and an apparatus for estimating direction of arrival of radar reception signal using antenna array extrapolation. Obtained is a transformation matrix representing a relationship between phases of reception signals received through ith to (N?2+i)th antennas and a phase of a reception signal received through (N?1+i)th antenna in a ULA antenna unit including N actual antennas. A phase of a virtual reception signal received through a new (N+i)th virtual antenna is generated by multiplying values corresponding to phases of the reception signals received through (i+1)th to (N?1+i)th antennas by the transformation matrix. A magnitude of the virtual reception signal received through the (N+i)th virtual antenna is obtained by averaging magnitudes of the reception signals received through ith to (N?1+i)th antennas.
