Publications*

*Due to the ongoing need for large publishing houses to have similar profit margins to Apple, I can only share post-print copies of papers here as part of 'Green Open Access' policies. Some of the following are 'Gold Open Access', meaning the fully formatted copy is uploaded, depending on journal embargo policies and (often) payments upon submission by us, the researchers (which often come from tax payers in the form of research grants). Some journals are more flexible than others. I can share post-print, formatted copies privately to interested researchers (see contact details on Home Page). I will update this list as I get around to it.
