Multiple Dielectric Relaxation Processes in Amorphous Polymers as a Function of Frequency, Temperature and Applied Pressure
It is well known (1,2) that most dipolar amorphous polymers exhibit multiple dielectric relaxation processes. At low temperatures the α and β processes are observed which, on raising the temperature at a given...

Low Frequency Dielectric Spectroscopy and Dynamic Kerr-Effect of Molecular Liquids
The reorientational motions of molecules in the supercooled liquid state and in liquid-crystal-forming materials just above the clearing point may occur on a time-scale which is far longer than that encountere...

Erratum: Optical technology: Novel optical properties of liquid–crystal polymers
Nature 326, 544-545 (1987). IN this News and Views piece this figure was poorly printed and details of shading lost. It is a schematic representation of the rich molecular architecture of liquid-crystalline po...

Dielectric Relaxation Properties and Alignment Behaviour of Liquid-Crystalline Side-Chain Polymers
We describe the alignment behaviour of different liquidcrystalline (LC) side-chain polymers when they are subjected to electrical/thermal treatments. It is shown that the alignment behaviour is determined by s...

Outlier Detection Using Replicator Neural Networks
We consider the problem of finding outliers in large multivariate databases. Outlier detection can be applied during the data cleansing process of data mining to identify problems with the data itself, and to ...

Association Rule Discovery with Unbalanced Class Distributions
There are many methods for finding association rules in very large data. However it is well known that most general association rule discovery methods find too many rules, many of which are uninteresting rules...

Conceptual Mining of Large Administrative Health Data
Health databases are characterised by large number of records, large number of attributes and mild density. This encourages data miners to use methodologies that are more sensitive to health undustry specifics...

Exploring Possible Adverse Drug Reactions by Clustering Event Sequences
Historically the identification of adverse drug reactions relies on manual processes whereby doctors and hospitals report incidences to a central agency. In this paper we suggest a data mining approach using a...

Temporal Sequence Associations for Rare Events
In many real world applications, systematic analysis of rare events, such as credit card frauds and adverse drug reactions, is very important. Their low occurrence rate in large databases often makes it diffic...
