Small Sample Bayesian Designs for Complex High-Dimensional Models Based on Information Gained Using Fast Approximations (2009)
Journal Article
Cumming, J., & Goldstein, M. (2009). Small Sample Bayesian Designs for Complex High-Dimensional Models Based on Information Gained Using Fast Approximations. Technometrics, 51(4), 377-388. https://doi.org/10.1198/tech.2009.08015

We consider the problem of designing for complex high-dimensional computer models that can be evaluated at different levels of accuracy. Ordinarily, this requires performing many expensive evaluations of the most accurate version of the computer mode...

A Markov random field model for extracting near-circular shapes (2009)
Presentation / Conference Contribution
Blaskovics, T., Kato, Z., & Jermyn, I. (2009, November). A Markov random field model for extracting near-circular shapes. Presented at 16th IEEE International Conference on Image Processing (ICIP) 2009, Cairo

We propose a binary Markov random field (MRF) model that assigns high probability to regions in the image domain consisting of an unknown number of circles of a given radius. We construct the model by discretizing the `gas of circles' phase field mod... Read More about A Markov random field model for extracting near-circular shapes.

Some rigorous results on semiflexible polymers, I: Free and confined polymers (2009)
Journal Article
Hryniv, O., & Velenik, Y. (2009). Some rigorous results on semiflexible polymers, I: Free and confined polymers. Stochastic Processes and their Applications, 119(10), 3081-3100. https://doi.org/10.1016/j.spa.2009.04.002

We introduce a class of models of semiflexible polymers. The latter are characterized by a strong rigidity, the correlation length associated with the gradient–gradient correlations, called the persistence length, being of the same order as the polym...

Exploring colourful holographic superconductors (2009)
Journal Article
Peeters, K., Powell, J., & Zamaklar, M. (2009). Exploring colourful holographic superconductors. Journal of High Energy Physics, 2009(09), Article 101. https://doi.org/10.1088/1126-6708/2009/09/101

We explore a class of holographic superconductors built using non-abelian condensates on probe branes in conformal and non-conformal backgrounds. These are shown to exhibit behaviour of the specific heat which resembles that of heavy fermion compound... Read More about Exploring colourful holographic superconductors.

Looking for shapes in two-dimensional, cluttered point clouds (2009)
Journal Article
Srivastava, A., & Jermyn, I. (2009). Looking for shapes in two-dimensional, cluttered point clouds. IEEE Transactions on Pattern Analysis and Machine Intelligence, 31(9), 1616-1629. https://doi.org/10.1109/tpami.2008.223

We study the problem of identifying shape classes in point clouds. These clouds contain sampled points along contours and are corrupted by clutter and observation noise. Taking an analysis-by-synthesis approach, we simulate high-probability configura... Read More about Looking for shapes in two-dimensional, cluttered point clouds.

A phase field higher-order active contour model of directed networks (2009)
Presentation / Conference Contribution
El Ghoul, A., Jermyn, I., & Zerubia, J. (2009, September). A phase field higher-order active contour model of directed networks. Presented at 2009 IEEE 12th International Conference on Computer Vision Workshops (Non-Rigid Shape Analysis and Deformable Image Alignment), at ICCV, Kyoto

The segmentation of directed networks is an important problem in many domains, e.g. medical imaging (vascular networks) and remote sensing (river networks). Directed networks carry a unidirectional flow in each branch, which leads to characteristic g... Read More about A phase field higher-order active contour model of directed networks.

A Thermodynamic Model of Microtubule Assembly and Disassembly (2009)
Journal Article
Piette, B., Liu, J., Peeters, K., Smertenko, A., Hawkins, T., Deeks, M., …Hussey, P. (2009). A Thermodynamic Model of Microtubule Assembly and Disassembly. PLoS ONE, 4(8), Article e6378. https://doi.org/10.1371/journal.pone.0006378

Microtubules are self-assembling polymers whose dynamics are essential for the normal function of cellular processes including chromosome separation and cytokinesis. Therefore understanding what factors effect microtubule growth is fundamental to our... Read More about A Thermodynamic Model of Microtubule Assembly and Disassembly.
