A major study initiative, “New Models of Dental Education,” funded by the Josiah Macy, Jr. Foundation, convened three panels of distinguished experts to examine issues related to the dental curriculum. This report is from Panel 3, held February 25–26, 2007, on the subject of genetics and its implications for clinical practice. Staffing the panel were Allan J. Formicola (The Macy Study), Richard...

The aim of this paper is to present the structure of a class of matrices that enables explicit inverse to be obtained. Starting from an already known class of matrices, we construct a Hadamard product that derives the class under consideration. The latter are defined by 4n − 2 parameters, analytic expressions of which provide the elements of the lower Hessenberg form inverse. Recursion formulae...

IT'WAS 1938, 20 years ago, when, in conversation with Professor R. A. Brink of the Department of Genetics at the University of Wisconsin, that I first heard of the work beingfr done in the Department of Agriculture to identify the substance in spoiled sweet clover accountable for hemorrhagic disease in cattle. This had been initially undertaken in 1934 at the Wisconsin Agricultural Experiment S...

continued on page 15 S erving as the Director of PATH for the past six years has been a very rewarding experience for me. I took over immediately after DEMO’97 from Professor Pravin Varaiya who had led PATH during the years of the NAHSC (National Automated Highway Systems Consortia). We faced some very difficult times after the demise of the NAHSC but were able to maintain our position as the l...

RETURNING now to the United States for a consideration of research developments there during the late fifties and early sixties. In reviewing the major publications of the time, one can see that the whole approach to the question of accident proneness was still one of openminded inquiry. Despite a certain amount of despondency over the lack of statistical evidence to support the concept (especi...

The low protein barley (Hordeum vulgare L.) cultivar ;Karl' is deficient in hordeins, the major storage protein fraction, but has normal levels of other endosperm protein fractions. We compared hordein gene expression in Karl with that in ;Traill,' a related cultivar that contains normal amounts of hordein. In plants grown in controlled environmental conditions, hordein accumulation in Karl was...

In this thesis I made a study of the properties of reactively sputtered ultra-thin films of niobium nitride (NbN) and niobium titanium nitride (NbTiN). Using Variable Angle Spectral Ellipsometry (VASE), I found that the optical properties of NbN films appear to have a critical thickness above which the optical parameters stabilize. I also found that the deposition process has better stability o...

Algebraic combinatorics for computational biology by Nicholas Karl Eriksson Doctor of Philosophy in Mathematics University of California, Berkeley Professor Bernd Sturmfels, Chair Algebraic statistics is the study of the algebraic varieties that correspond to discrete statistical models. Such statistical models are used throughout computational biology, for example to describe the evolution of ...
