    Multiscale characterization reveals oligomerization dependent phase separation of primer-independent RNA polymerase nsp8 from SARS-CoV-2

    RNA replication and transcription machinery is an important drug target for fighting against coronavirus. Non-structure protein nsp8 was proposed harboring primase activity. However, the RNA primer synthesis m...

    Minimum distances of three families of low-density parity-check codes based on finite geometries

    Three families of low-density parity-check (LDPC) codes are constructed based on the totally isotropic subspaces of symplectic, unitary, and orthogonal spaces over finite fields, respectively. The minimum dist...

    Association schemes of quadratic forms over a finite field of characteristic two

    For the association schemes of quadratic forms over a finite field of characteristic two, the parameters of this association scheme are discussed by using matrix skill. Forn = 2, 3, all the parameters are compute...
