Product Perfect Codes and Steganography [PDF]

, 2009
A new coding technique to be used in steganography is evaluated. The performance of this new technique is computed and comparisons with the well-known theoretical upper bound, Hamming upper bound and basic LSB are ...

Enhancing Imperceptibility: Zero-width Character-based Text Steganography for Preserving Message Privacy

Acta Informatica Pragensia
Background: Text steganography preserves the privacy of secret messages by hiding them in cover text. However, existing text steganography techniques embed messages by introducing distortions in text, reducing the similarity between the cover and ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Computational Methods of Digital Steganography

Izvestiya of Altai State University
The paper reviews current digital steganography techniques for photo and video content. It introduces a neural-network algorithm for covert data transmission in video streams. The architecture of computational methods blends 2D and 3D convolutions: the 2D layers preserve fine frame details, while the 3D layer averages features across three neighboring ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Unified Evaluation System for Audio Steganography Methods

Scientific Journal of Riga Technical University. Computer Sciences, 2011
The interest in the digital steganography grows together with the rise of amounts of multimedia data exchanged over the Internet. This growth provides steganography with new possibilities and opportunities for data hiding. The information hiding in audio streams is considered especially promising due to audio data popularity and possibilities to hide ...
