Photolithographic Patterning of Bi-Helical Tracks onto Conical Substrates (2007)
Journal Article
Purvis, A., McWilliam, R., Johnson, S., Seed, N., Williams, G., Maiden, A., & Ivey, P. (2007). Photolithographic Patterning of Bi-Helical Tracks onto Conical Substrates. Journal of Micro/Nanopatterning, Materials, and Metrology, 6(4), https://doi.org/10.1117/1.2824377

We demonstrate the direct photolithographic patterning of a grossly non-planar substrate by creating 62 micron helical tracks on a 22 mm high cone. The projection of focused light on to the three dimensional surface is achieved using a computer gener... Read More about Photolithographic Patterning of Bi-Helical Tracks onto Conical Substrates.

Medium- and large-scale characterization of UMTS-allocated frequency division duplex channels (2007)
Journal Article
Salous, S., & Gokalp, H. (2007). Medium- and large-scale characterization of UMTS-allocated frequency division duplex channels. IEEE Transactions on Vehicular Technology, 56(5), 2831-2843. https://doi.org/10.1109/tvt.2007.900495

A dual-band sounder is used in both trolley and van measurements in the dense urban environment of Manchester city center to characterize the uplink (1920-1980 MHz) and downlink (2110-2170 MHz) frequency-division duplex (FDD) channels allocated to th...

Computing the hybridisation number of two phylogenetic trees is fixed parameter tractable (2007)
Journal Article
Bordewich, M., & Semple, C. (2007). Computing the hybridisation number of two phylogenetic trees is fixed parameter tractable. IEEE/ACM Transactions on Computational Biology and Bioinformatics, 4(3), 458-466. https://doi.org/10.1109/tcbb.2007.1019

Reticulation processes in evolution mean that the ancestral history of certain groups of present-day species is non-tree-like. These processes include hybridization, lateral gene transfer, and recombination. Despite the existence of reticulation, suc...

Geodesic Flow on Global Holomorphic Sections of TS^2 (2007)
Journal Article
Klingenberg, W., & Guilfoyle, B. (2007). Geodesic Flow on Global Holomorphic Sections of TS^2. Bulletin of the Belgian Mathematical Society Simon Stevin (Printed), 14(2), 363-371

We study the geodesic flow on the global holomorphic sections of the bundle π:TS2→S2π:TS2→S2 induced by the neutral Kähler metric on the space of oriented lines of R3R3, which we identify with TS2TS2. This flow is shown to be completely integrable wh... Read More about Geodesic Flow on Global Holomorphic Sections of TS^2.

A Reduction Algorithm for Computing the Hybridization Number of Two Trees (2007)
Journal Article
Bordewich, M., Linz, S., St. John, K., & Semple, C. (2007). A Reduction Algorithm for Computing the Hybridization Number of Two Trees. Evolutionary Bioinformatics, 3, 86-98

Hybridization is an important evolutionary process for many groups of species. Thus, conflicting signals in a data set may not be the result of sampling or modeling errors, but due to the fact that hybridization has played a significant role in the e...

Computing the minimum number of hybridisation events for a consistent evolutionary history (2007)
Journal Article
Bordewich, M., & Semple, C. (2007). Computing the minimum number of hybridisation events for a consistent evolutionary history. Discrete Applied Mathematics, 155(8), 914-928. https://doi.org/10.1016/j.dam.2006.08.008

It is now well-documented that the structure of evolutionary relationships between a set of present-day species is not necessarily tree-like. The reason for this is that reticulation events such as hybridizations mean that species are a mixture of ge...
