Web2 days ago · Although CPSF73 is universally required for mRNA 3' end formation, we have unexpectedly found that Compound 2-mediated inhibition of pre-mRNA 3' processing is sequence-specific and that the sequences flanking the cleavage site (CS) are a major determinant for drug sensitivity. Webthat each spreading sequence should have low PAPR for multicarrier transmission, in addition to low coherence of the spreading matrix. As a consequence, we believe that theoretically bounded low coherence and low PAPR of spreading sequences are essential for the success of CS-based joint CE and MUD in uplink grant-free NOMA.
