A liquid crystal display device includes a liquid crystal cell, polarizers, a first retardation plate arranged between the liquid crystal cell and the first polarizer, and a second retardation plate arranged between the liquid crystal cell and the second polarizer. The peptides may contain other amino acid residues including non-natural amino acids. The system also includes Enqueue logic that operates to compute an expiration time for each received packet based on the receive time indicator, and stores the expiration time and the sequence identifier for each received packet into a table.
