Publish/subscribe system captures the dynamic aspect of the specified information by notifying users of interesting events as soon as possible. Fast response time is important for event filtering which requires multiple step processing and is also one of important factors to provide good service for subscribers. Generally the event arrival rate is time varying and unpredictable. It is very poss...

External dynamic hashing has been used in traditional database systems as a fast method to answer membership queries. Given a dynamic set S of objects, a membership query asks whether an object with identity k is in the most current S. This paper addresses the more general problem of Temporal Hashing. In this setting changes to the dynamic set are timestamped and the membership query has a temp...

Developing better technologies to adapt to a changing world is crucial for the growth of a knowledge-based economy. Indeed, new products in the areas of energy, pharmaceuticals, and telecommunications generate significant economic benefits. However, in order to maximise those benefits, firms need to devise research and development (R&D) strategies that are responsive to market conditions. We ta...

The success of biopharmaceuticals started about 30 years ago with the first production of recombinant human insulin (Humulin®) in Escherichia coli, followed by the first production of human tissue plasminogen activator (tPA) in mammalian host cells some years later. Due to the lack of glycosylation in E. coli, which is required for the biological activity of most monoclonal antibodies, the use ...
