Origin of atomic clusters during ion sputtering (2001)
Journal Article
Rehn, L., Birtcher, R., Donnelly, S., Baldo, P., & Funk, L. (2001). Origin of atomic clusters during ion sputtering. Physical review letters, 87(20), 207601-1-207601-4. https://doi.org/10.1103/PhysRevLett.87.207601

Previous studies have shown that the size distributions of small clusters ( n<=40 n = number of atoms/cluster) generated by sputtering obey an inverse power law with an exponent between -8 and -4. Here we report electron microscopy studies of the... Read More about Origin of atomic clusters during ion sputtering.

The dependence on structure of the projected vibrational density of states of various phases of ice as calculated by ab initio methods (2001)
Journal Article
Jenkins, S., & Morrison, I. (2001). The dependence on structure of the projected vibrational density of states of various phases of ice as calculated by ab initio methods. Journal of Physics: Condensed Matter, 13(41), 9207-9229. https://doi.org/10.1088/0953-8984/13/41/312

We determine the structural data of seven of the polymorphs of ice (ice Ih, ice Ic, ice IX, ice II, ice VI, ice VII and ice VIII) from ab initio calculations. The dynamical properties have been analysed within the harmonic approximation via a finite-...

Are grammatical representations useful for learning from biological sequence data?— a case study (2001)
Journal Article
Muggleton, S., Bryant, C., Srinivasan, A., Whittaker, A., Topp, S., & Rawlings, C. (2001). Are grammatical representations useful for learning from biological sequence data?— a case study. Journal of Computational Biology, 8(5), 493-521. https://doi.org/10.1089/106652701753216512

This paper investigates whether Chomsky-like grammar representations are useful for learning cost-effective, comprehensible predictors of members of biological sequence families. The Inductive Logic Programming (ILP) Bayesian approach to learning fr... Read More about Are grammatical representations useful for learning from biological sequence data?— a case study.

Comparison of microbiology, filter media and plant communities within constructed wetlands treating wastewater contaminated with heavy metals (2001)
Presentation / Conference Contribution

The aim was to investigate the treatment efficiency of passive vertical-flow wetland filters containing different plant communities (predominantly Phragmites Australis and/or Typha Latifolia) and granular media with different adsorption capacities in...

Diffractive origin of fractal resonator modes (2001)
Journal Article
New, G., Yates, M., Woerdman, J., & Mcdonald, G. (2001). Diffractive origin of fractal resonator modes. Optics Communications, 193(1-6), 261-266. https://doi.org/10.1016/S0030-4018%2801%2901237-8

The modes of unstable optical resonators possess fractal character. In this paper, the fundamental question of how and why fractals originate in one of the simplest linear optical systems is addressed. The answer is related to the fact that unstabl...

Synthesis and characterization of a novel Y-Fe phase via kinetic neutron diffraction (2001)
Journal Article
Kilcoyne, S., Manuel, P., & Ritter, C. (2001). Synthesis and characterization of a novel Y-Fe phase via kinetic neutron diffraction. Journal of Physics: Condensed Matter, 13(22), 5241-5250. https://doi.org/10.1088/0953-8984/13/22/317

Kinetic in situ neutron diffraction has been used to study the crystallization of
amorphous Y67Fe33. The results show that partial crystallization first occurs
close to 300 ◦C where the Y phase is formed. The entire sample crystallizes
at 390 ◦C a... Read More about Synthesis and characterization of a novel Y-Fe phase via kinetic neutron diffraction.

The aim of this study was to investigate the treatment efficiency of passive vertical-flow wetland filters containing Phragmites australis and/or Typha latifolia and granular media of different adsorption capacities. A cost–benefit analysis was perfo... Read More about Comparison of filter media, plant communities and microbiology within constructed wetlands treating wastewater containing heavy metals.

Non-paraxial beam propagation methods (2001)
Journal Article
Chamorro-Posada, P., Mcdonald, G., & New, G. (2001). Non-paraxial beam propagation methods. Optics Communications, 192(1-2), 1-12. https://doi.org/10.1016/S0030-4018%2801%2901171-3

Exact analytical results are employed in the testing of split-step and finite difference approaches to the numerical solution of the non-paraxial non-linear Schrodinger equation. It is shown that conventional split-step schemes can lead to spurious o... Read More about Non-paraxial beam propagation methods.
