Patent number: 12574052Abstract: Neural Normalized MinSum (N-NMS) decoding for improving frame error rate (FER) performance on linear block codes over conventional normalized MinSum (NMS). Dynamic multiplicative weights are assigned to each check-to-variable message in each iteration to efficiently provide training parameters of N-NMS that support N-NMS for longer block lengths. Embodiment are described for neural two-dimensional normalized MinSum (N-2D-NMS) decoders requiring fewer training parameters. The N-2D-NMS approaches for example use the same weight for edges with the same check and/or variable node degree. Simulation results indicate that that this LDPC decoding performs similarly to previous techniques while substantially reducing the amount of training necessary.Type: GrantFiled: August 30, 2023Date of Patent: March 10, 2026Assignees: The Regents of the University of California, California Institute of TechnologyInventors: Richard D.

Publication number: 20240218393Abstract: Provided herein are viral vectors comprising a transgene encoding a compact effector protein and uses thereof. These effector proteins are shown to be active with guide RNAs and may be characterized as CRISPR-associated (Cas) proteins. Due to the small nature of the effector protein, the viral vector has ample room for additional genome editing cargo, such as a guide nucleic acid and a donor nucleic acid. Various compositions, systems, and methods of the present disclosure leverage the activities of these effector proteins for the modification, detection, and engineering of nucleic acids.Type: ApplicationFiled: January 16, 2024Publication date: July 4, 2024Inventors: Pei-Qi LIU, Wiputra Jaya HARTONO, Lucas Benjamin HARRINGTON, Sean CHEN
