The basis of the present volume is, of course, the sections on immunity in the earlier book, but there has been considerable re-arrangement, t...

In order to test the hypothesis that P. falciparum parasites can modify the permeability of the membrane to specific solutes by epigenetic regulation of clag3 genes expression, in article 1 of this thesis we explored the role of switches in clag3 expression in the acquisition of resistance to the antibiotic BS. To fulfil this aim, we selected 10G parasites, which under standard culture conditio...

A theory of shape is important for AI both for recognition and description of objects and for reasoning about the possible behaviours of objects. Theories of shape may be loosely classified as either volume-based or outline-based. We present a theory of the latter type, initially confined to two-dimensional outlines. We represent outlines by means of strings over an alphabet of seven qualitativ...

Background. A primary aim in generative linguistics is to discover the computational principles underlying our ability to speak. A specific problem occupying much of my work is how to relate the symbolic aspects of our speaking competence to their continuous physical manifestation in terms of vocal tract action. The study of these two aspects of speech has traditionally been pursued under separ...

This paper outlines a system called Arizona, now under development at the U. of Washington. Arizona is intended to be a portable, public-domain collection of tools supporting scientific computing, quantitative graphics, and data analysis, implemented in Common Lisp[31] and CLOS (the Common Lisp Object System)[4]. Although there is substantial implementation of some of the modules described belo...
