We investigate natural extensions of the Continuous Image Graph (CIG) labelling scheme, which is based on the Consecutive Ones Property of matrices. The CIG labelling scheme generalizes tree labelling schemes to many graphs yet remaining as efficient, i.e., adjacency tests run in constant time, the space requirement is constant per node, and testing whether a graph is a CIG is possible in polyn...

Consumers’ views of genetically modified foods (GM foods) can influence food producers’ decisions as to whether to market GM foods or whether to use conventional varieties. Through labelling, supported by certification, consumers could differentiate a GM food from a conventional food. A working group of the Codex Committee on Food Labelling identified seven approaches to labelling of GM foods. ...

We propose a method for labelling prepositional phrases according to two different semantic role classifications, as contained in the Penn treebank and the CoNLL 2004 Semantic Role Labelling data set. Our results illustrate the difficulties in determining preposition semantics, but also demonstrate the potential for PP semantic role labelling to improve the performance of a holistic semantic ro...

Here we describe the application of a new click chemistry method for fluorescent tracking of protein synthesis in individual microorganisms within environmental samples. This technique, termed bioorthogonal non-canonical amino acid tagging (BONCAT), is based on the in vivo incorporation of the non-canonical amino acid L-azidohomoalanine (AHA), a surrogate for l-methionine, followed by fluoresce...

Successful evaluation of X- and Y-chromosome-bearing sperm separation technology using flow cytometry-cell sorter is of great importance. Fluorescence in situ hybridization (FISH), which allows for the detection of specific nucleic acid sequences on morphologically preserved spermatozoa, is an ideal method for quantitatively and qualitatively assessing the purity of sorted sperm samples. In thi...

We apply the methods developed in [Br1] to study holomorphic functions of slow growth on coverings of pseudoconvex domains in Stein manifolds. In particular, we extend and strengthen certain results of Gromov, Henkin and Shubin [GHS] on holomorphic L2 functions on coverings of pseudoconvex manifolds in the case of coverings of Stein manifolds.

This paper presents a strategy for matching features in multiple images, which emphasises reliable matching and the recovery of feature extraction errors. The process starts from initial ‘good’ matches, which are validated in multiple images using multi-image constraints. These initial matches are then filtered through a relaxation procedure and are subsequently used to locally predict addition...

The lack of contextual integrity in region labelling schemes for segmented visual images has been a long standing problem in computer vision. In the past it has been common to adopt some form of relaxation scheme, such as relaxation labelling, to remove both labelling ambiguities and labellings which, usually, are obviously contextually incorrect. So far no general region labelling system has b...
