The fundamental limits to the attenuation of hollow-core photonic crystal fibres (2005)
Birks, T. A., Roberts, P. J., Couny, F., Sabert, H., Mangan, B. J., Williams, D. P., ...
We propose that the transmission of hollow-core photonic crystal fibres is ultimately limited by scattering from roughness due to frozen-in surface capillary waves. This is confirmed by measurements...

Thesis (Ph. D.)--Arizona State University, 1987.
Williams, D.P., Parker, K., Bacha, P., Bishai, W., Borowski, M., Genbauffe, F., ...
We have genetically replaced the diphtheria toxin receptor binding domain with a synthetic gene encoding interleukin-2 (IL-2) and a translational stop signal. The diphtheria toxin-related T-cell...
Williams, D P, Regier, D, Akiyoshi, D, Genbauffe, F, Murphy, J R
A synthetic gene encoding human interleukin-2 (IL-2) was designed such that the codon usage bias resembled that found in highly expressed Escherichia coli genes. The percentage of preferred codons...
