Psychovisual Evaluation of Image Segmentation Algorithms (2002)
Presentation / Conference Contribution
Shaffrey, C., Jermyn, I., & Kingsbury, N. (2002, September). Psychovisual Evaluation of Image Segmentation Algorithms. Presented at Advanced Concepts for Intelligent Vision Systems, Ghent, Belgium

Evaluation plays an important role in the advancement of any field. In computer vision, unsupervised segmentation algorithms, although of great interest, often suffer from lack of a well-defined goal and/or explicit ground truth data, thus rendering...

Additional stringy sources for electric dipole moments. (2002)
Journal Article
Abel, S., Khalil, S., & Lebedev, O. (2002). Additional stringy sources for electric dipole moments. Physical Review Letters, 89(12-16),

We show that string models with low energy supersymmetry which accommodate the fermion mass hierarchy generally give non-universal soft trilinear couplings (A-terms). In conjunction with the apparently large Cabibbo-Kobayashi-Maskawa (CKM) phase, thi... Read More about Additional stringy sources for electric dipole moments..

We briefly summarize the main results presented at the IPPP workshop on Multiparticle Production in QCD Jets, held in Durham in December 2001. (From the workshop 'Multiparticle Production in QCD Jets', 12–15 December 2001)

Stabilizing textures with magnetic fields (2002)
Journal Article
Ward, R. (2002). Stabilizing textures with magnetic fields. Physical Review D, Particles and fields, 66(4), Article 041701(R). https://doi.org/10.1103/physrevd.66.041701

The best-known way of stabilizing textures is by Skyrme-like terms, but another possibility is to use gauge fields. The semilocal vortex may be viewed as an example of this, in two spatial dimensions. In three dimensions, however, the idea (in its si... Read More about Stabilizing textures with magnetic fields.

Noncommutative D-brane and open string in pp-wave background with B-field (2002)
Journal Article
Chu, C., & Ho, P. (2002). Noncommutative D-brane and open string in pp-wave background with B-field. Nuclear Physics B, 636(1-2), 141-158. https://doi.org/10.1016/s0550-3213%2802%2900360-7

The open string ending on a D-brane with a constant B-field in a pp-wave Ramond–Ramond background is exactly solvable. The theory is controlled by three dimensionful parameters: α′, the mass parameter (RR background times the lightcone momentum) and...

Skyrmed Monopoles. (2002)
Journal Article
Grigoriev, D., Sutcliffe, P., & Tchrakian, D. (2002). Skyrmed Monopoles. Physics Letters B, 540(1-2), 146-152. https://doi.org/10.1016/s0370-2693%2802%2902141-x

We investigate multi-monopole solutions of a modified version of the BPS Yang–Mills–Higgs model in which a term quartic in the covariant derivatives of the Higgs field (a Skyrme term) is included in the Lagrangian. Using numerical methods we find tha... Read More about Skyrmed Monopoles..

Quelques calculs de la cohomologie de GL_N(Z) et de la K-theorie de Z (2002)
Journal Article
Elbaz-Vincent, P., Gangl, H., & Soulé, C. (2002). Quelques calculs de la cohomologie de GL_N(Z) et de la K-theorie de Z. Comptes Rendus Mathématique, 335(4), 321-324. https://doi.org/10.1016/s1631-073x%2802%2902481-0

Voronoi cell decomposition is used to determine most of the structure of the homology of GL_N(Z) for N=5, 6. This determines K_5(Z) and gives that K_6(Z) is a 3-group.

Aspects of the homogeneous sine-Gordon models (2002)
Presentation / Conference Contribution
Dorey, P., & Miramontes, J. L. (2002, July). Aspects of the homogeneous sine-Gordon models. Presented at Workshop on Integrable Theories, Solitons and Duality, Sao Paulo

The physical mass scales that determine the behaviour of general (simply-laced) Homogeneous Sine-Gordon models are investigated by means of a study of their finite-size effects, using the thermodynamic Bethe ansatz. These models describe integrable m... Read More about Aspects of the homogeneous sine-Gordon models.

Sharp global nonlinear stability for temperature dependent viscosity convection (2002)
Journal Article
Straughan, B. (2002). Sharp global nonlinear stability for temperature dependent viscosity convection. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 458(2023), 1773-1782. https://doi.org/10.1098/rspa.2001.0945

With regard to the dependence of viscosity on temperature, an unconditional non-linear energy-stability analysis for thermal convection according to Navier-Stokes theory has not yet been developed. We here analyse three models of fluid behaviour prop... Read More about Sharp global nonlinear stability for temperature dependent viscosity convection.
