Abstract: A managed network element is partitioned into one or more virtual network elements. The managed network element may be partitioned based on physical components or services provided by that network element. Each virtual network element is then provided a respective agent to monitor and manage its portion of the managed network element.

Abstract: Constitutive and tissue-specific protein factors which bind to transcriptional regulatory elements of Ig genes (promoter and enhancer) are described. The factors were identified and isolated by an improved assay for protein-DNA binding. Genes encoding factors which positively regulate transcription can be isolated and employed to enhance transcription of Ig genes. In particular, NF-kB, the gene encoding NF-kB, IkB and the gene encoding IkB and uses therefor.

Abstract: A method for archiving, indexing and disseminating poster abstracts is provided.

Abstract: A computer process, a computing system or an article of manufacture for processing a secure transaction. A process of accepting a secure transaction from a lockbox that stores private information accessible via a security protocol includes the steps of accepting a transaction initiated by a lockbox, determining whether the transaction was initiated by a lockbox, and identifying the transaction as a lockbox transaction. The method can include the step of determining what security protocol was used to initiate the transaction.

Abstract: The adhesion between a locomotive drive wheel and supporting rail can be substantially increased by application of a powder mixture that contains a hard particle constituent preferably including alumina, a soft particle constituent preferably including titania, and an iron oxide constituent. The mixture may be in the form of a dry powder, a paste with water or alcohol vehicle, or a metal composite that includes the powder.

Abstract: At least one powered disc is suspended from a locomotive and applied to a rail surface for treating the rail surface ahead of driven locomotive wheels to increase adhesion between the driven wheels and the rail surface. Torque applied to the disc varies the rate of rotation of the disc away from that of a freely-rotating disc so that a significant level of creep may be maintained between the disc and the rail surface with substantially no angle of attack between the disc and the longitudinal axis of the rail. The torque may be generated through a second disc contacting the rail and coupled to the first disc with the first and second discs rotating with differing rates of rotation, or may be generated through a passive or active actuator coupled directly to the disc. The amount of creep between the disc and the rail surface and the direction of the creep may be varied in accordance with the level of contamination of the rail and the disc may be disengaged from the rail when cleaning is not required.

Abstract: A valve assembly is disclosed which is adapted to fit existing valve bodies. A flexible diaphragm assembly positioned within the valve body seals against a cylindrical barrel of the valve body. A central tube positioned within the central barrel defines a bypass passage extending from an upper chamber above the flexible diaphragm assembly and communicating with a bypass orifice. A sealing mechanism operated by an automatic control mechanism is adapted to selectively seal the bypass orifice. The automatic control mechanism includes a proximity sensor.

Abstract: A method of exchanging entries on calendars being maintained by a first and a second calendar users. An event is automatically scheduled on a second calendar if a classification which is associated with the event is higher than any previous scheduled event for the same time slot. A reply is prepared and transmitted to the first calendar user which requested the scheduling of the vent regarding the status of the second user in regards to the scheduled event. Subsequently, if the status of the second user changes in regards to the event, a subsequent reply is prepared and transmitted to the first user setting forth the changed status.

Abstract: A closure for a chamber having an interior which can contain a fluid under pressure provides apparatus for latching the door of the chamber in its closed position and locking it in that position when the positive pressure within the chamber reaches a predetermined level. The closure includes a door that is moved by positive pressure within the chamber and, through appropriate mechanisms, activates locking apparatus that prevents the door from leaving its closed position as long as such pressure is present within the chamber.
