Working Group on Diffraction: Executive Summary. (2009)
Presentation / Conference Contribution
Arneodo, M., Diehl, M., Khoze, V., & Newman, P. (2009, March). Working Group on Diffraction: Executive Summary. Presented at 2nd workshop on the implications of HERA for LHC physics, Hamburg - Geneva

We give a brief overview of the topics covered in the working group on diffraction.

Rapidity gap survival probability and total cross sections. (2009)
Presentation / Conference Contribution
Martin, A., Khoze, V., & Ryskin, M. (2009, March). Rapidity gap survival probability and total cross sections. Presented at 2nd workshop on the implications of HERA for LHC physics, Hamburg - Geneva

We discuss recent calculations of the survival probability of the large rapidity gaps in exclusive processes of the type pp → p + A + p at high energies. Absorptive or screening effects are important, and one consequence is that the total cross secti... Read More about Rapidity gap survival probability and total cross sections..

Shear Unzipping of DNA (2009)
Journal Article
Chakrabarti, B., & Nelson, D. (2009). Shear Unzipping of DNA. Journal of Physical Chemistry B (Soft Condensed Matter and Biophysical Chemistry), 113(12), 3831-3836. https://doi.org/10.1021/jp808232p

We study theoretically the mechanical failure of a simple model of double-stranded DNA under an applied shear. Starting from a more microscopic Hamiltonian that describes a sheared DNA, we arrive at a nonlinear generalization of a ladder model of she... Read More about Shear Unzipping of DNA.

Diffractive processes at the LHC. (2009)
Presentation / Conference Contribution
Martin, A., Khoze, V., & Ryskin, M. (2009, March). Diffractive processes at the LHC. Presented at Diffraction 2008: International Workshop on Diffraction in High Energy Physics, La Londe‐les‐Maures, France

We present a model of high energy soft pp interactions that has multi s‐ and t‐channel components, which has been tuned to describe all the available data. The t‐channel components allow matching of the soft to the hard (QCD) Pomeron. Absorptive effe... Read More about Diffractive processes at the LHC..

Two-loop multi-gluon amplitudes in N=4 SYM from Wilson loops (2009)
Presentation / Conference Contribution
Heslop, P. J. (2009, March). Two-loop multi-gluon amplitudes in N=4 SYM from Wilson loops. Presented at 44th Rencontres de Moriond on QCD and High Energy Interactions, La Thuile, Italy

The Wilson loop/amplitude duality for N=4 SYM states that planar n-point MHV amplitudes arc equivalent to n-gon lightlike Wilson loops. This has been proved analytically for all n at one loop. At two loops it has been shown numerically up to 6 points... Read More about Two-loop multi-gluon amplitudes in N=4 SYM from Wilson loops.

Anisotropic, nonsingular early universe model leading to a realistic cosmology (2009)
Journal Article
Dechant, P., Lasenby, A., & Hobson, M. (2009). Anisotropic, nonsingular early universe model leading to a realistic cosmology. Physical Review D, 79(4), Article 043524. https://doi.org/10.1103/physrevd.79.043524

We present a novel cosmological model in which scalar field matter in a biaxial Bianchi IX geometry leads to a nonsingular “pancaking” solution: the hypersurface volume goes to zero instantaneously at the “big bang”, but all physical quantities, such...

The Correlation between Variate-Values and Ranks in Samples from Complete Fourth Power Exponential Distribution (2009)
Journal Article
Maturi, T., & Elsayigh, A. (2009). The Correlation between Variate-Values and Ranks in Samples from Complete Fourth Power Exponential Distribution. Journal of Mathematics Research, 1(1), 14-18. https://doi.org/10.5539/jmr.v1n1p14

In this paper, we derive the correlation between variate-values and ranks in a sample from the Complete Fourth Power Exponential (CFPE) distribution. A sample from the CFPE distribution could be misclassified as if it is drawn from the normal distrib...

Soft processes at the LHC. I. Multi-component model. (2009)
Journal Article
Ryskin, M., Martin, A., & Khoze, V. (2009). Soft processes at the LHC. I. Multi-component model. The European Physical Journal C, 60(2), 249-264. https://doi.org/10.1140/epjc/s10052-009-0889-2

We emphasise the sizeable effects of absorption on high-energy ‘soft’ processes, and, hence, the necessity to include multi-pomeron–pomeron interactions in the usual multi-channel eikonal description. We present a model which includes a complete set... Read More about Soft processes at the LHC. I. Multi-component model..

Applying the imprecise Dirichlet model in cases with partial observations and dependencies in failure data (2009)
Journal Article
Troffaes, M., & Coolen, F. (2009). Applying the imprecise Dirichlet model in cases with partial observations and dependencies in failure data. International Journal of Approximate Reasoning: Uncertainty in Intelligent Systems, 50(2), 257-268. https://doi.org/10.1016/j.ijar.2008.03.013

Imprecise probabilistic methods in reliability provide exciting opportunities for dealing with partial observations and incomplete knowledge on dependencies in failure data. In this paper, we explore the use of the imprecise Dirichlet model for deali...

Group theory of icosahedral virus capsid vibrations: a top-down approach (2009)
Journal Article
Peeters, K., & Taormina, A. (2009). Group theory of icosahedral virus capsid vibrations: a top-down approach. Journal of Theoretical Biology, 256(4), 607-624. https://doi.org/10.1016/j.jtbi.2008.10.019

We explore the use of a top-down approach to analyse the dynamics of icosahedral virus capsids and complement the information obtained from bottom-up studies of viral vibrations available in the literature. A normal mode analysis based on protein ass... Read More about Group theory of icosahedral virus capsid vibrations: a top-down approach.
