This study represents a joint pilot project between archaeological and natural sciences, aimed at exploring the technology and provenance of gold artefacts, exemplified for the case of Georgia. It is focussed on the prehistoric gold mine of Sakdrisi. The study included the investigation of both Bronze Age gold artefacts and native gold by chemical and lead isotope analyses using ICP-mass spectr...

This talk presents an overview of our work on databases in DNA performed over the past four years, joint with my student Joris Gillis and postdoc Robert Brijder. Our goal is to better understand, at a theoretical level, the database aspects of DNA computing. The talk will be self-contained and will begin with an introduction to DNA computing. We then introduce a graph-based data model of so-cal...

INUCLEATED cells occur in a variety of tissues in plants and animals normally and under varying physiological conditions (e.g., anemia, stress, ageing, regeneration, malignancy and viral infection) (BLOOM 1968). Among animals, naturally occurring binucleated cells have been observed in organisms of the following classes: Protozoa, Nematoda, Crustacea, Arachnida, Insecta, Agnatha, Pisces, Amphib...
