Methods, articles of manufacture, and systems for improving the efficiency of executing queries are provided. The socket includes an outer conductor and a center conductor. A redundancy determination result is reflected on read data by activation of control signals \u03c61 and \u03c62 given immediately prior to a sense amplifier. The probability that each of the trial sequences could have resulting in all of trial sequences is calculated to determine a monomer sequence with the highest probability of resulting in all of the trial sequences, termed the first iteration sequence. The server-side transaction accelerator reconstructs the message by replacing the reference with segment data in a persistent segment store accessible to the server-side transaction accelerator. The carbide layer provides an etch stop for etching the overlying oxide layer, and the underlying oxide layer provides an etch stop for etching the carbide layer to form an emitter-base contact opening.
