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.

CeSR + Assisted LDPC: A Holistic Strategy to Improve MLC NAND Flash Reliability

IEEE Access, 2020
NAND flash suffers from program interference and retention errors, which negatively affect its reliability. Existing schemes preprocess raw data before writing them to reduce Raw Bit Error Rate (RBER) and leverage ECCs (such as LDPC codes) to reduce ...

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 ...

Doped low-density parity-check codes

Digital Communications and Networks
In this paper, we propose a doping approach to lower the error floor of Low-Density Parity-Check (LDPC) codes. The doping component is a short block code in which the information bits are selected from the coded bits of the dominant trapping sets of the ...

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
