The interplay of geometrical and Andreev quantization in mesoscopic superconductors leads to giant mesoscopic oscillations of energy levels as functions of the Fermi momentum and/or sample size. Quantization rules are formulated for closed quasiparticle trajectories in the presence of normal scattering at the sample boundaries. Two generic examples of(More)
The authors consider two new attacks on watermarked video specific to HD 60 fps H.264 High and Main profiles: selective I/P frames' removal and zeroing of residuals in B frames. We propose the method of embedding of a readable watermark for H.264 High Profile video robust to such attacks. The video stream is partially decoded removing entropy coding, then a(More)
