Abstract: A variety of embodiments for hardware-accelerating the processing of financial market depth data are disclosed. A coprocessor, which may be resident in a ticker plant, can be configured to update order books and price books based on financial market depth data at extremely low latency. Such a coprocessor can also be configured to enrich a stream of limit order events pertaining to financial instruments with data from a plurality of updated order and price books.

Abstract: The present invention provides for managing network connections to one or more domains in a processor-based system. An apparatus is provided that comprises a storage unit and a control unit. The storage unit is adapted to store a domain list and a path list, wherein the domain list comprises a domain defined in a system and the path list comprises one or more paths available for communications with the domain. The control unit is communicatively coupled to the storage unit, wherein the control unit adapted to determine an active path from the one or more available paths and to transmit data to the domain over the active path.

Abstract: Disclosed is a substituted 6-nitroquipazine of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are each selected from the group consisting of H, Fl, CL, Br, I, CF.sub.3, CH.sub.2 CH.sub.2 F, CH.sub.3, CH.sub.2 CH.sub.3, and --CH(CH.sub.3).sub.2, and wherein one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is other than H.Also disclosed is a method for measurement of serotonin uptake sites in a sample, in which a radioligand is incubated with a sample and then the radioactivity of the radioligand bound to the sample is determined, utilizing a radio labeled substituted 6-nitroquipazine as the radioligand. Also disclosed is a method of manufacture and method of use.
