Abstract: A system and method to manage a network by monitoring an interface of the network. The system comprises a poller, a server, and a database. The poller checks the interface through a poller query message to the interface. Upon suspected failure, the poller sends an alert signal to the server notifying the server that the interface may be failing. The server may send out a server query signal to the interface and monitor the response to determine if a failure occurred. The database contains information concerning the interface. When the server determines that the interface has failed, the server pulls information concerning the interface and sends an alarm signal to a client application module.

Abstract: We describe methods and compositions for setting and maintaining the state of gene expression in a cell. The genetic circuit clocked latch has two states with each state corresponding to a different pattern of gene expression. The genetic circuit clocked latch allows one to set the state of the latch only when the clock signal is active. When the clock signal is inactive, the state of the latch is maintained as the state when the clock signal was last active. The clocked latch consists of gating circuitry and a bistable switch. The circuit is implemented as nucleic acid constructs. By analogy with a similar circuit found in digital electronics, such a circuit is expected to have an increased immunity to input fluctuations and is expected to facilitate the design of large circuits composed of multiple latches.

Abstract: A system used to manage a network by monitoring at least one interface of the network comprises a poller, a server, and a database, all in communication with one another. The poller continuously checks the at least one interface of the network by continuously sending out a poller query message to at least one interface of the network. The poller suspects a first interface of at least one interface of failing when the poller does not receive a poller reply message in response to the query messages from the first interface within a first time period. The poller sends an alert signal to the server notifying the server that the first interface of the at least one interface may be failing when the poller suspects the first interface of the at least one interface is failing.

Abstract: The recovery of the sequence of bases in a dideoxyribonucleic acid (DNA) molecule is important for both research and medical applications. The standard processing techniques are prone to error. This invention creates from the template a new set of molecules which introduce an error correcting code as might be used in data communications. After the usual processing associated with DNA sequencing, the code can be used to reduce the errors in the estimated sequence.

Abstract: A system for analyzing communication network events on a historical basis based on records received from the network. A data processing system is connected via a first communications co-processor to a node of the network, permitting access to the node processor event log. In response to an inquiry sent from the data processing system, the events are collected as they are reported to the node processor. A record of the events is made in a table corresponding to the particular type of event received. The records in all tables may be sorted based on dates supplied by a system operator. The sorted records comprise a report identifying particular network elements which constituted an event during the reporting period.

Abstract: A method for simulating an IDNX (integrated digital network exchange) network. Trunk and call information is downloaded from a network controller connected to the IDNX network to a personal computer. Call data is obtained defining each call placed over the network. Link data is also obtained describing the links over which the call is placed. The link data is arranged in two arrays, one defining a pointer based on the identity of connected nodes. The pointers point to a table which describes the link interconnecting the nodes. A call circuit table identifies each of the calls over the network. The call is placed on the model by debiting the in use bandwidth field of the table describing each link used in the call. Once calls are placed, an analysis of network performance is possible. Calls may be rerouted over the simulated model to evaluate different network configurations.
