IL‐33‐Induced TREM2+ Macrophages Promote Pathological New Bone Formation Through CREG1‐IGF2R Axis in Ankylosing Spondylitis

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.

Generalized simplified variable-scaled min sum LDPC decoder for irregular LDPC codes [PDF]

2014 IEEE 25th Annual International Symposium on Personal, Indoor, and Mobile Radio Communication (PIMRC), 2014
In this paper, we propose a novel low complexity scaling strategy of min-sum decoding algorithm for irregular LDPC codes. In the proposed method, we generalize our previously proposed simplified Variable Scaled Min-Sum (SVS-min-sum) by replacing the sub-optimal starting value and heuristic update for the scaling factor sequence by optimized values ...

Cost‐Effective DNA Storage System with DNA Movable Type

Advanced Science, Volume 12, Issue 9, March 6, 2025.
This study presents a cost‐effective “DNA‐movable‐type storage” system inspired by movable type printing. Utilizing reusable prefabricated DNA‐MTs and an automated inkjet printer, BISHENG‐1 stores and retrieves 43.7 KB of data in vitro and in vivo with only 350 DNA‐MTs, achieving storage costs of $122 MB−1–significantly more cost‐efficient than ...

Non-Binary LDPC Codes with Large Alphabet Size

, 2014
We study LDPC codes for the channel with input ${x}\in \mathbb{F}_q^m$ and output ${y}={x}+{z}\in \mathbb{F}_q^m$. The aim of this paper is to evaluate decoding performance of $q^m$-ary non-binary LDPC codes for large $m$.

A low‐complexity block EP‐based detector for iterative detection and decoding in unsourced random access

Electronics Letters, Volume 61, Issue 1, January/December 2025.
Here, a multi‐user signal iterative detection and decoding scheme named LBEP based on block expectation propagation (BEP) is proposed for LDPC‐coded two‐phase unsourced random access (URA) scheme. In the iteratively process, the approximation of matrix inversion is used to facilitate expectation propagation (EP). The numerical results show that, in the

LDPC DropConnect

, 2023
Machine learning is a popular topic that has become a scientific research tool in many fields. Overfitting is a common challenge in machine learning, where the model fits the training data too well and performs poorly on new data. Stochastic regularization is one method used to prevent overfitting, by artificially constraining the model to be simpler ...

5G‐coded fluid antenna multiple access over block fading channels

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This letter investigates the use of 5G New Radio (NR) Modulation Coding Scheme (MCS) for FAMA systems to improve its connectivity over block fading channels. In particular, we propose an iterative decoding receiver with iterative interference covariance estimation, designed explicitly for slow fading channels.

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization

EURASIP Journal on Wireless Communications and Networking, 2008
This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection. Part I showed that a special class of DE-LDPC codes, product accumulate
