Construction of Multi-Rate QC-LDPC Codes Based on Permutation Method

This paper proposes a systematic permutation-based construction method for multi-rate quasi-cyclic low-density parity-check (QC-LDPC) codes. We first present a graph-theoretic framework in which any regular QC-LDPC code can be normalized to a canonical base matrix that is uniquel...

Enhancing Mn(II)/Mn(IV) Redox Activity and Reducing Polarization of NASICON‐Type Na 3 MnTi(PO 4 ) 3 Through Al‐Doping

ABSTRACT NASICON‐type cathode materials have garnered significant interest for their stable structure and favorable Na + diffusion pathways. However, Na 3 MnTi(PO 4 ) 3 (NMTP) often suffers from substantial voltage hysteresis and limited capacity, primarily attributed to intrinsi...

Advances of KO t Bu‐Involved Reactions in Organic Synthesis From 2020 to 2025

Potassium tert-butoxide (KOtBu), a strong non-nucleophilic base with a pKa value of 17.5, has emerged as a versatile and indispensable reagent in modern organic synthesis. Notably, KOtBu can promote a wide range of bond-forming transformations that conventionally rely on transiti...
