Garlick, W., Wyn-Williams, M., Rumsey, N., Clarke, A., & White, P. (2004). Altered body image: Appearance-related concerns of people with visible disfigurement. Journal of Advanced Nursing, 48(5), 443-453. https://doi.org/10.1111/j.1365-2648.2004.03227.x

Aim. The aim of this paper is to report a study to establish the extent and type of psychosocial needs of outpatients attending for treatment of a wide range of disfiguring conditions. Background. Visible disfigurements can be associated with extensi... Read More about Altered body image: Appearance-related concerns of people with visible disfigurement.

Improvement in collective performance with experience in ants (2004)
Journal Article
Langridge, E. A., Franks, N. R., & Sendova-Franks, A. B. (2004). Improvement in collective performance with experience in ants. Behavioral Ecology and Sociobiology, 56(6), 523-529. https://doi.org/10.1007/s00265-004-0824-3

We show that entire ant colonies can improve their collective performance progressively when they repeat the same process. Colonies of Leptothorax albipennis can reduce their total emigration times over successive emigrations. We show that this impro...

Algorithms for building annular structures with minimalist robots inspired by brood sorting in ant colonies (2004)
Journal Article
Wilson, M., Melhuish, C., Sendova-Franks, A. B., & Scholes, S. (2004). Algorithms for building annular structures with minimalist robots inspired by brood sorting in ant colonies. Autonomous Robots, 17(2-3), 115-136. https://doi.org/10.1023/B%3AAURO.0000033969.52486.3d

This study shows that a task as complicated as multi-object 'ant-like annular sorting' can be accomplished with 'minimalist' solutions employing simple mechanisms and minimal hardware. It provides an alternative to 'patch sorting' for multi-object so... Read More about Algorithms for building annular structures with minimalist robots inspired by brood sorting in ant colonies.

Some demands on rapid prototypes used as master patterns in rapid tooling for injection moulding (2004)
Journal Article
Venus, A., Dunne, P., Soe, S., Byrne, G., & Wheatley, A. R. (2004). Some demands on rapid prototypes used as master patterns in rapid tooling for injection moulding. Journal of Materials Processing Technology, 150(3), 201-207. https://doi.org/10.1016/S0924-0136%2803%2900571-5

Injection moulded components are finding vigorously increasing applications in numerous sectors. The flexibility of the process allows complex components to be manufactured in high volumes in fully automated environments. Associated with such compone...

Use of External Magnetic Fields to Reduce Reaction Times in an Immunoassay Using Micrometer-Sized Paramagnetic Particles as Labels (Magnetoimmunoassay) (2004)
Journal Article
Luxton, R., Badesha, J., Kiely, J., & Hawkins, P. (2004). Use of External Magnetic Fields to Reduce Reaction Times in an Immunoassay Using Micrometer-Sized Paramagnetic Particles as Labels (Magnetoimmunoassay). Analytical Chemistry, 76(6), 1715-1719. https://doi.org/10.1021/ac034906%2B

The paper presents a rapid immunoassay system capable of quantifying analyte in complex biological and environmental media. Antibody-coated micrometer-sized paramagnetic particles are used as labels in an assay in which they bind quantitatively with...

Self propagating high temperature synthesis of magnesium zinc ferrites (MgxZn1-xFe2O3): Thermal imaging and time resolved X-ray diffraction experiments (2004)
Journal Article
Spiers, H., Parkin, I. P., Pankhurst, Q. A., Affleck, L., Green, M., Caruana, D. J., …Kvick, A. (2004). Self propagating high temperature synthesis of magnesium zinc ferrites (MgxZn1-xFe2O3): Thermal imaging and time resolved X-ray diffraction experiments. Journal of Materials Chemistry, 14(7), 1104-1111. https://doi.org/10.1039/b314159b

Spinel ferrites of the form Mg Zn Fe O (x = 0. 0.25, 0.50, 0.75, 1.00) were prepared by self-propagating high-temperature synthesis (SHS) from reactions of iron(III), zinc and magnesium oxides, iron powder and sodium perchlorate. The driving force... Read More about Self propagating high temperature synthesis of magnesium zinc ferrites (MgxZn1-xFe2O3): Thermal imaging and time resolved X-ray diffraction experiments.

Finite time extinction in nonlinear diffusion equations (2004)
Journal Article
Beardmore, R. E., Peplow, A. T., & Laister, R. (2004). Finite time extinction in nonlinear diffusion equations. Applied Mathematics Letters, 17(5), 561-567. https://doi.org/10.1016/S0893-9659%2804%2990126-7

We consider a class of degenerate diffusion equations where the nonlinearity is assumed to be singular (non-Lipschitz) at zero. It is shown that solutions with compactly supported initial data become identically zero in finite time. Such extinction f... Read More about Finite time extinction in nonlinear diffusion equations.

Building better nurse scheduling algorithms (2004)
Journal Article

The aim of this research is twofold: Firstly, to model and solve a complex nurse scheduling problem with an integer programming formulation and evolutionary algorithms. Secondly, to detail a novel statistical method of comparing and hence build bette... Read More about Building better nurse scheduling algorithms.

Sequential and continuum bifurcations in degenerate elliptic equations (2004)
Journal Article
Beardmore, R. E., & Laister, R. (2004). Sequential and continuum bifurcations in degenerate elliptic equations. Proceedings of the American Mathematical Society, 132(01), 165-174. https://doi.org/10.1090/S0002-9939-03-06979-X

We examine the bifurcations to positive and sign-changing solutions of degenerate elliptic equations. In the problems we study, which do not represent Fredholm operators, we show that there is a critical parameter value at which an infinity of bifurc...

We consider a class of differential-algebraic equations (DAEs) defined by analytic nonlinearities and study its singular solutions. The main assumption used is that the linearization of the DAE represents a Kronecker index-2 matrix pencil and that th... Read More about Trajectories of a DAE near a pseudo-equilibrium.
