Rheumatoid arthritis (RA) is a debilitating systemic autoimmune disorder that significantly impairs quality of life. To elucidate the molecular alterations in RA progression, we performed comprehensive super-omics analyses on synovial tissues from patients with joint trauma, arthritis, and RA. These included transcriptomics, proteomics, metabolomics, microbiomics, fourteen PTMs (phosphorylation, acetylation, lactylation, O-GlcNAc glycosylation, arginine monomethylation, lysine dimethylation,...
Interior design, which integrates art and science, is vulnerable to infringements such as copying tampering. The unique often intricate nature of these designs makes them unauthorized replication misuse, posing significant challenges for designers seeking protect their intellectual property. To solve the above problems, we propose a deep learning-based zero-watermark copyright protection method. method aims embed undetectable information through image fusion technology without destroying...
