Abstract: This invention relates to the prediction of protein sequence interactions. A method and apparatus are described for discovering rules of protein sequence interactions using a machine learning approach. The system uses a database of known protein sequence interactions, an algorithm to asses predictive quality of rules on one or more subsets of a protein sequence interaction database and a technique for generating new rule sets for testing. The system aims to optimise a rule set (descriptors of protein sequence interactions) against one or more predetermined criteria. One or more pairs of protein sequences which are likely to interact are generated according to the rule sets thus generated.

Abstract: A user interface for a network security policy monitoring system and method that performs network and security assessments based on system-wide policy, whereby real network traffic is analyzed to identify abnormalities, vulnerabilities, and incorrect configurations by listening on a network, logging events, and taking action.

Abstract: A system and method for generating a human readable, e.g. English language, description of a formal specification of network security policy that allows non-technical staff within a user's organization to comprehend the policy. The description is simple enough to be understood, yet captures salient details of the policy.

Abstract: A method and apparatus uses a proprietary algorithm for organizing network security policy rules in a way that minimizes the number of rules considered when determining the set of rules applicable to a given protocol event.

Abstract: A method and apparatus ascertain which credential and which condition both from a network security policy best describe, respectively, information about initiator and target principals involved in an interaction, and tests performed on a state of an associated protocol event.

Abstract: An electric arc discharge lamp comprises a cathode (2), an apertured diaphragm (4) and a cup shaped apertured anode (6). The anode (6) is provided with a flared extension (7) and is mounted on leads passing through ceramic tubes (14) (FIG. 4). The cathode (2) is enclosed in a cup shaped member comprising a cylindrical tube (5) having one end closed by the diaphragm (4). The electrodes are enclosed in a sealed envelope (8) (FIG. 4) which is filled with deuterium. A synthetic quartz window (81) is provided in one end of the envelope to enable ultra-violet radiation from the arc struck between the cathode and anode to pass through.The cathode (2), the aperture (42) in the diaphragm (4) and the aperture (62) in the anode (6) are aligned and lie on the axis of symmetry of the envelope (8). The anode is an efficient heat radiator because of its large surface area and thus works at a lower than normal temperature allowing the use of stainless steel rather than the usual refractory metals.
