In this letter, we propose a two-stage design method to construct memory efficient mutual information-maximizing quantized min-sum (MIM-QMS) decoder for rate-compatible low-density parity-check (LDPC) codes. We first develop modified density evolution unique set of lookup tables (LUTs) that can be used LDPC The constructed LUTs are optimized based on their discrepancy values and merge function ...

Dihydroxymethyl radical (1) was found to react with oxygen diffusion controlled (k = 4.5 x 109 M _ 1 s 1 ) . The final products of the reaction are formic acid and 1/2 hydrogen peroxide. The precursor of H2O2 was shown to be O2' which is formed with G(02" -) = 6.3 (a value which includes the 02"~ formed by H atoms and oxygen (G(H) = 0.55)). If it is assumed that dihydroxymethylperoxyl radicals ...
