Low error floor LT coding algorithm by using fixed-length node classification window

Tongxin xuebao, 2021
To solve the problem of high error floor for LT codes in additive white Gaussian noise (AWGN) channels, an improved coding scheme was designed.A fixed-length classification window was used to sort out the information nodes with relatively small degrees ...

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.

Degradation Improvement in BER Due to Various Sources of Noise in Optical Transceivers

Journal of Engineering and Sustainable Development, 2005
The quality of digital communications whether at radio or optical frequencies depends primarily on the Bit Error Rate (BER). Reducing the BER improves the communication system behavior.

Performance of probabilistic amplitude shaping with BICM‐ID

Electronics Letters, 2021
It is numerically shown that bit error rate (BER) performance of probabilistic amplitude shaping (PAS) applying a bit‐to‐symbol mapping of non‐Gray natural binary code assigned to 64‐quadrature amplitude modulation is significantly improved by bit ...

Hyperglycaemia‐induced reactive oxygen species production in cardiac ventricular myocytes differs among mammals

The Journal of Physiology, EarlyView.
Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

De Novo Genome Assemblies of Four Rainbow Trout Genetic Lines Reveal Structural Variants in Pursuit of a Pangenome Reference

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Rainbow trout (Oncorhynchus mykiss) exhibit extensive genomic diversity shaped by domestication, life history and geographic origin. To advance the development of a comprehensive pangenome reference, we present new de novo genome assemblies of two genetically and ecologically distinct lines: Whale Rock (WR; wild, landlocked, Central California)

Guiding Curiosity: How Learning Progress Shapes Young Children's Exploration of New Toys

Developmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT Previous research has shown that children are drawn to environments that offer learning progress. However, the computational implementation of learning progress varied across studies, potentially overshadowing that there might be two distinct processes at work.
