Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length
, 2017 In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...

Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.Hardware experiments show a single‐layer Quantum Memory Matrix booster cuts logical error sixfold and, when prepended to a [3,1,3]$[3,1,3]$ repetition code, attains 94 % logical fidelity without extra CX gates. QMM dressing also lowers variational‐training loss by 35 %, offering a measurement‐free, resource‐light route to error suppression on NISQ ...

Improving the efficiency of the LDPC code-based McEliece cryptosystem through irregular codes
, 2013 We consider the framework of the McEliece cryptosystem based on LDPC codes, which is a promising post-quantum alternative to classical public key cryptosystems.

eFood, Volume 6, Issue 4, August 2025.Cordyceps cicadae mycelium extracts (CCME) have been reported to exert beneficial effects on ocular diseases. TV, TBUT, and cornea surface indexes were improved with oral CCME intake. Immunohistochemical assays showed that p63 + , PCNA, NF‐κB and COX‐2 expressions decreased in the CCME group than that of the UVB group. The corneas of those treated with

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]
, 2013 Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

LDPC Coded Massive MIMO Systems [PDF]
Entropy, 2019 We design a coded massive multiple-input multiple-output (MIMO) system using low-density parity-check (LDPC) codes and iterative joint detection and decoding (JDD) algorithm employing a low complexity detection. We introduce the factor graph representation of the LDPC coded massive MIMO system, based on which the message updating rule in the JDD is ...

High speed error correction for continuous-variable quantum key distribution with multi-edge type LDPC code [PDF]
Scientific Reports, 2017 Error correction is a significant step in postprocessing of continuous-variable quantum key distribution system, which is used to make two distant legitimate parties share identical corrected keys.

Advanced Science, Volume 12, Issue 18, May 15, 2025.This study identifies TREM2+ macrophages as key contributors to pathological bone formation in ankylosing spondylitis (AS). These macrophages mediate pathological new bone formation via the CREG1‐IGF2R‐PI3K‐AKT pathway and are regulated by IL‐33 through STAT6 phosphorylation.

Spatially-Coupled MacKay-Neal Codes and Hsu-Anastasopoulos Codes
, 2011 Kudekar et al. recently proved that for transmission over the binary erasure channel (BEC), spatial coupling of LDPC codes increases the BP threshold of the coupled ensemble to the MAP threshold of the underlying LDPC codes.
