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.

A Note on the Girth of (3, 19)-Regular Tanner’s Quasi-Cyclic LDPC Codes

IEEE Access, 2021
In this article, we study the cycle structure of (3, 19)-regular Tanner’s quasi-cyclic (QC) LDPC codes with code length $19p$ , where $p$ is a prime and $p\equiv 1~(\bmod ~57)$ , and transform the conditions for the existence of cycles of ...

Extended Barrel-Shifter for Versatile QC-LDPC Decoders [PDF]

IEEE Wireless Communications Letters, 2020
In this letter, we present a Barrel-Shifter of size ${n}$ extended by an additional layer that can handle any circular permutation on a vector of size ${m}$ , ${m}~{\pmb {\leq }}~{n}$ , thanks to a specific initial positioning of the data.

Classical channel bandwidth requirements in continuous variable quantum key distribution systems

IET Quantum Communication, Volume 5, Issue 4, Page 601-611, December 2024.
The reconciliation method for continuous variable quantum key distribution (CV‐QKD) systems is usually chosen based on its reconciliation efficiency. Nonetheless, one must also consider the requirements of each reconciliation method in terms of the amount of information transmitted on the classical channel. Such may limit the achievable key rates.

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.

Design of Multiple-Edge Protographs for QC LDPC Codes Avoiding Short Inevitable Cycles [PDF]

, 2013
There have been lots of efforts on the construction of quasi-cyclic (QC) low-density parity-check (LDPC) codes with large girth. However, most of them focus on protographs with single edges and little research has been done for the construction of QC ...

Reordered static layered schedule for 5G low‐density parity‐check codes

Electronics Letters, Volume 60, Issue 7, April 2024.
A static layered schedule for the 5G low‐density parity‐check codes is proposed here. The proposed static layered schedule provides better error performance and faster convergence speed than state‐of‐the‐art. Abstract The error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers.
