The systematic utility of sequences from a non-coding region of chloroplast DNA (cpDNA) between psbA and trnH (6v6) was examined by assessing phylogenetic relationships in subtribe Sonchinae (Asteraceae: Lactuceae). Primers constructed against highly conserved regions of tRNA genes were used for PCR amplification and sequencing. The psbA-trnH intergenic spacer contains several insertions and de...

Naturally established individuals of Plantago lanceolata with the inflorescence disease caused by Fusarium moniliforme var. subglutinans had more inflorescences and were more likely to be male-sterile than healthy plants. Half-sib families planted in the field varied in the percentage of diseased plants, the number of inflorescences per plant, the incidence of male-sterility, and the pattern of...

A high-speed signal travelling through a backplane is subject to high-frequency losses, primarily skin effect and dielectric losses. These losses can severely degrade and attenuate the high-frequency content of the signal, making it difficult for the receiver to interpret the signal. Stratix® IV GX devices offer pre-emphasis and linear equalization to address this problem and improve the high-s...

The next generation of control systems are likely to be characterised by much higher integration, where common / shared computer resources perform multiple system functions. It is possible to reconfigure such systems to provide continued functionality when an element of the system fails. To achieve this aim a number of pre-requisites must be in-place: the ability to determine when a failure has...

We demonstrate a low-power wireline transmitter with 2-tap pre-emphasis in which serialization is achieved by toggling serializer with data transition information extracted from parallel input data. This novel technique of serialization provides significantly reduced power consumption since it does not need the short pulse generation block required in the conventional serializer. In addition, t...

We applied a standard facial caricaturing algorithm to a three-dimensional representation of human heads. This algorithm sometimes produced heads that appeared \caricatured". More commonly, however, exaggerating the distinctive three-dimensional information in a face seemed to produce an increase in the apparent age of the face | both at a local level, by exaggerating small facial creases into ...

In the field of law, decisions in previous cases often play a significant role in the presentation and outcome of new cases. Lawyers are constantly recalling old cases to aid them in preparing their own briefs. How do lawyers remember cases? What are the features they use to organize and retrieve past decisions? How do lawyers learn which features are important? To address these Questions we ar...
