Conventional paper-based scientific publications are limited in the amount of data and interaction they can provide. Simply placing an electronic copy of such a publication on the web makes for easier distribution, but more can be achieved by making use of the technology to navigate through the paper, to show the links between calculated parameters and the… (More)
In this paper we discuss the information system requirements of an e-Science scenario, drawn from chemistry research, and describe our approach to a solution which employs notions of adaptive (and adaptable) hypermedia and utilises Semantic Web technologies. 1. Introduction: The Chemical Aether The typical chemist operates in a space that contains a rich… (More)
We report on one aspect of our research into text-free, speech recognition-free lip synchronization (lip-sync). By lip-sync we mean inputting freely spoken speech and outputting parameters for animating a mouth, which can then be synchronized with the input speech. We first describe a " pitch tracker " that we find helps to expedite the identification of… (More)
Using the eigenvalue definition of binomial states we construct new intermediate number-coherent states which reduce to number and coherent states in two different limits. We reveal the connection of these intermediate states with photon-added coherent states and investigate their non-classical properties and quasi-probability distributions in detail. It is… (More)
A necessary and sufficient condition for the maximal entanglement of bipartite nonorthogonal pure states is found. The condition is applied to the maximal en-tanglement of coherent states. Some new classes of maximally entangled coherent states are explicited constructed; their limits give rise to maximally entangled Bell-like states.
Intermediate states interpolating coherent states and Pegg-Barnett phase states are investigated using the ladder operator approach. These states reduce to coherent and Pegg-Barnett phase states in two different limits. Statistical and squeezing properties are studied in detail.
