Approaches to obtaining fingerprints of steganography tools which embed message in fixed positions
Recently, more and more steganography tools are exploited to embed malicious code into images by attackers, which bring harm to society. Thus, it has been a tricky problem, for which needs to detect the stego-images correctly.

Coverless Image Steganography: A Survey
With the digitalization of information, a lot of multimedia data are under attack, information security has become a key issue of public concern. Image steganography, aiming at using cover images to convey secret information has become one of the most challenge and important subjects in the field of information security recently.

Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Steganographically Encoded Data [PDF]
Steganography is the art of hiding information in ways that prevent its detection. Though steganography is an ancient craft, the onset of computer technology has given it new life.

Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Histogram preserving QIM-based watermarking [PDF]
Quantisation-based watermarking schemes are known to be strongly robust to noise and widely applied for image authentication. However, such schemes tend to create specific patterns in the histogram of the watermarked image, thus opening security gap for ...

A Robust joint coverless image steganography scheme based on two independent modules
With the development of deep learning technology, great progress has been made in the field of coverless steganography based on deep learning technology, including some selection-based steganography methods that use deep learning technology and all ...

Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
