In this study, using Group Permutation Low-Density Parity-Check (GP-LDPC) codes, the authors generalise the concept of array Low-Density Parity-Check (LDPC) codes from fields of prime order to those of prime power order. In fact, they consider the additive group of the finite field GF(q...

Section VII generalizes the MDS code construction to arbitrary number of parity columns. These generalized codes have similar properties as the (k+2, k) MDS array codes, likewise some of them has optimal ratio. Rebuilding of multiple erasures and generalization of the rebuilding algorithms are ...
In the solar corona, the presence of free electrons gives rise to a plasma frequency denoted byωp, serving as the effective mass for the EM wave. This quantity is determined by the free electron densitynein the non-relativistic plasma, and can be represented as ...
Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal to the solar plas

A method for constructing an extended array of storage devices that enables storage of more than one parity block per stripe on a single device of the array is disclosed. Each devic
In 1962, Gallager first introduced Low-Density Parity-Check (LDPC) codes as a type of linear block code characterized by their sparse parity-check matrix [1], which distinguishes them from general linear block codes. In 1981, Tanner proposed using bipartite graphs to describe the parity-check ...
