Abstract: Various aspects of a requested transport or delivery service can be modelled and computationally represented using different classes of statechart objects. Some of the statechart objects can be transitioned between one or more composite states each having a plurality of substates. In this manner, delays, errors, and failures relating to the transport or delivery service can be tracked using state transitions of the statechart objects. And dynamic recovery functions to such delays, errors, and failures can be performed in response.

Abstract: A network system is configured to model various aspects of fulfilling service requests using hierarchical statechart objects. The statechart objects can be instantiated and/or transitioned to different states in response to user requests and/or detected service events. Furthermore, the statechart objects can be dynamically linked such that state transitions of one statechart object can trigger the state(s) of one or more other linked statechart objects to be transitioned. A transaction coordinator is configured to identify a set of related state transitions and determine whether each of the set of related state transitions has been successfully completed. In response to determining that each of the set of related state transitions has been successfully completed, the transaction coordinator can cause data entries to be written to a database.

Abstract: The present invention relates to a novel method for the delivery of agents to tumour cells. In particular it relates to a method for the specific delivery of agents to the interior of tumour cells. Uses of the method are also described.

Abstract: The invention provides a method for analyzing a nucleic acid, comprising cleaving the nucleic acid into multiple fragments at a defined sequence, and selectively amplifying individual fragments to produce a map by a modified HAPPY mapping technique.
