The present invention is related to systems and methods for implementing commission allocations in transaction management of auction-based trading for specialized items such as interest-rate-related instruments. The improvement can be accomplished by bringing the photoresist layer after the post-exposure baking treatment into contact with an aqueous acidic solution having a pH of 3. Particularly improved results in fluid contacting processes can be achieved by enhanced mixing within a wicking layer within a microchannel. The arm has a pin portion protruding into the chamber. The major components of the power supply device may be implemented as an integrated circuit.
