Two “mirror” nuclei, in which the numbers of neutrons and protons are interchanged, have markedly different shapes—a finding that defies current nuclear theories.

This paper proposes a novel lossless informationhiding scheme that hides information in locally adaptive compressed codes. The scheme is abbreviated as IHLAC for wider the efficiency of the compressed codes. IHLAC is designed for two objectives; one is to compress a text file; the other is to hide secret information in it. According to the experimental results, IHLAC can easily and efficiently ...

An optimized method for data hiding into a digital color image in spatial domainis provided. The graph coloring theory with different color numbers is applied. To enhance thesecurity of this method, block correlations method in an image is used. Experimental results showthat with the same PSNR, the capacity is improved by %8, and also security has increased in themethod compared with other meth...
