QMM‐Enhanced Error Correction: Demonstrating Reversible Imprinting and Retrieval for Robust Quantum Computation

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 ...

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 ...

Utilizing Cordyceps cicadae Mycelium as a Potential Supplement for Alleviating UVB‐Induced Photokeratitis Symptoms In Vivo

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

Protograph EXIT Analysis over Block Fading Channels with Application to Relays

, 2012
An accurate extrinsic information transfer (EXIT) analysis is developed for protograph low-density parity-check (LDPC) codes over the block fading channel (BFC). The analysis is thus exploited for analyzing the behavior of distributed protograph LDPC

Equivalent-Capacity-Based Design of Space-Time Block-Coded Sphere-Packing-Aided Multilevel Coding [PDF]

, 2007
A multilevel coding (MLC) scheme invoking sphere packing (SP) modulation combined with space time block coding (STBC) is designed. The coding rates of each of the MLC component codes are determined using the so-called equivalent capacity based ...

Research on unequal error protection of irregular LDPC codes

Tongxin xuebao, 2005
An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.

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 ...

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

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.
