The existing tamper detection Massage Chair schemes for absolute moment block truncation coding (AMBTC) compressed images are able to detect the tampering.However, the marked image qualities of these schemes can be enhanced, and their authentication methods may fail to detect some special tampering.We propose a secure AMBTC tamper detection scheme
We review the distribution of the Buff-fronted Owl Aegolius harrisii harrisii in Peru, supported by unpublished museum records and new Sanitary Pads specimens and observations.Compared to previous published records, the distribution and elevation range for the species in Peru are expanded significantly.Based on all records, we Leg Support deduce th
In embryonic stem (ES) cells, bivalent chromatin domains with overlapping repressive (H3 lysine 27 tri-methylation) and activating (H3 lysine 4 tri-methylation) histone modifications mark the promoters of more than 2,000 genes.To gain insight into the structure and function of bivalent domains, we mapped key histone modifications and subunits of Po
