We develop a class of examples in the form of tiling dynamical systems for use as toy models in statistical mechanics, to analyze the possible existence of disordered crystals. We give the first such models which are disordered in the sense of having no discrete spectrum. * Research supported in part by a grant from the Israel Science and Technology Ministry ** Research supported in part by NSF...

Ortony and Turner's (1990) arguments against those who adopt the view that there are basic emotions are challenged. The evidence on universals in expression and in physiology strongly sug~ests that ~he~e is a biological basis to the emotions that have been studied.

From 10% to 20% of obese people studied do not show the metabolic changes common in obese patients. The term "healthy obese" has been coined to refer to these patients and differentiate them from the larger and more common group of pathological obese subjects. However, the definition of "he...

Children in the back seat on a long trip are not the only ones asking the question “Are we there yet?” At Murray State University (MSU) and other universities starting new programs, the question becomes one of validation of the program. In the late 90s, MSU, a midsize university, was entrusted with the responsibility of developing a program of distinction with financial support from special sta...

This presidential address is keyed to the exhibition "All of Us Are Related, Each of Us Is Unique." It reveals that there are no biological barriers between the 5.7 billion human beings that today inhabit the earth. We all have the same ancestors and the genetic diversity of contemporary human populations reflects the paths followed by our ancestors in the course of human migrations over the pa...
