Impressed by the elegance and simplicity of the Popov frequency criterion and the concept of hyperstability, I have joined in October 1967 (for one year) the group of V.M. Popov at the Energy Institute of the Romanian Academy with the objective to apply the Popov theory to adaptive systems and real-time identification. From the interpretation of the Popov stability criterion in terms of an equi...

UNDERSTANDING AND ENGINEERING THE COLLAGEN TRIPLE HELIX Matthew Donald Shoulders Under the supervision of Professor Ronald T. Raines At the University of Wisconsin-Madison This thesis presents a hypothesis-driven approach to collagen research that integrates the power of organic chemistry with the tools of biophysics to enhance our understanding of proline conformation and collagen structure an...

THIS VOLUME is a selection of 28 papers taken from the Fourth Yale Workshop on Applications of Adaptive Systems Theory held in May 1985 at Yale University. The Yale workshops on adaptive control were first organized in 1979. The period 1980-1985 is especially significant in adaptive system theory, for it was during this period of time that the major results in what is now called robust adaptive...

The discovery of hyperthermophilic microorganisms and the analysis of hyperthermostable enzymes has established the fact that multisubunit enzymes can survive for prolonged periods at temperatures above 100°C. We have carried out homology-based modeling and direct structure comparison on the hexameric glutamate dehydrogenases from the hyperthermophiles Pyrococcus furiosus and Thermococcus litor...
