An improved method for counting 6-cycles in low-density parity-check codes [PDF]

Serbian Journal of Electrical Engineering, 2023
Since their rediscovery in the early 1990s, low-density parity-check (LDPC) codes have become the most popular error-correcting codes owing to their excellent performance. An LDPC code is a linear block code that has a sparse parity-check matrix.

A Comprehensive Review of Low Density Parity Check Encoder Techniques

Ingénierie des Systèmes d'Information, 2022
This paper presents a survey on various technologies of low density parity check encoder. LDPC codes are capable to handle high speed communication channel, by reducing attenuation, hazards and efficiently rectifying the linear error correction.

Blockchain technologies as enablers of supply chain mapping for sustainable supply chains

Business Strategy and the Environment, Volume 31, Issue 8, Page 3742-3756, December 2022., 2022
Abstract The advent of blockchain technologies is transmuting the way conventional supply chains are being managed. Due to the complexity of dealing with many actors involved in the supply chain networks, contemporary supply chains have limited visibility, transparency, and accountability.

Bandwidth Efficient and Rate-Matched Low-Density Parity-Check Coded Modulation [PDF]

IEEE Transactions on Communications, 2015
A new coded modulation scheme is proposed. At the transmitter, the concatenation of a distribution matcher and a systematic binary encoder performs probabilistic signal shaping and channel coding.

Defining the pig microglial transcriptome reveals its core signature, regional heterogeneity, and similarity with human and rodent microglia

Glia, Volume 71, Issue 2, Page 334-349, February 2023., 2023
Main Points Defined a pig microglial transcriptome signature comprising 239 genes. Demonstrated regional variance in the pig microglial transcriptome across the brain. Revealed similarity of pig microglial gene expression to that of human and mouse microglia.

On Girth Conditioning for Low-Density Parity-Check Codes [PDF]

IEEE Transactions on Communications, 2011
Low-density parity-check (LDPC) codes are gaining interest for high data rate applications in both terrestrial and spatial communications. They can be designed and studied through a bipartite graph whose characteristics affect the performance. This paper proposes a low-complexity method to improve the performance of LDPC codes by selectively removing ...

DNA methylation biomarkers for noninvasive detection of triple‐negative breast cancer using liquid biopsy

International Journal of Cancer, Volume 152, Issue 5, Page 1025-1035, 1 March 2023., 2023
What's new? While early diagnosis of triple‐negative breast cancer (TNBC) is associated with heightened responsiveness to chemotherapy, biomarkers that can be detected noninvasively are needed to support early TNBC diagnosis. Our study suggests that such markers may exist in the form of methylation signatures in cell‐free DNA. Evaluation of methylation

Decoding across the quantum low-density parity-check code landscape

Physical Review Research, 2020
We show that belief propagation combined with ordered statistics post-processing is a general decoder for quantum low-density parity-check codes constructed from the hypergraph product.

Longitudinal Change in Bone Density, Geometry, and Estimated Bone Strength in Older Men and Women From The Gambia: Findings From the Gambian Bone and Muscle Aging Study (GamBAS)

Journal of Bone and Mineral Research, Volume 38, Issue 1, Page 48-58, January 2023., 2023
ABSTRACT Musculoskeletal aging in the most resource‐limited countries has not been quantified, and longitudinal data are urgently needed to inform policy. The aim of this prospective study was to describe musculoskeletal aging in Gambian adults. A total of 488 participants were recruited stratified by sex and 5‐year age band (aged 40 years and older ...

Rate‐compatible spatially coupled LDPC code ensembles by partial repetition extension

IET Communications, Volume 17, Issue 2, Page 246-252, January 2023., 2023
Abstract Herein, one partial repetition extension method is proposed to construct the rate‐compatible spatially coupled low‐density parity‐check (RC‐SCLDPC) codes. For each position of the base SCLDPC code, a certain proportion of the variable nodes are first selected randomly and then repeated a certain number of times.
