Aerenchyma formation in roots of maize ( Zea mays L.) involves programmed death of cortical cells that is promoted by exogenous ethylene (1 μ L L −1 ) or by endogenous ethylene produced in response to external oxygen shortage (3%, v/v). In this study, evidence that degeneration of the cell wall accompanies apoptotic-like changes previously observed in the cytoplasm and nucleus (Gunawardena et a...

Almost all results in model theory of arithmetic are about elementary extensions. I will talk about an effort to systematize those results. If M and N are models of arithmetic and M ≺ N , how much information is there in Th((N,M)) in relation to Th(N)? In what situations is there a form of elimination of quantifiers for Th((N,M))? Is there a complete set of isomorphism invariants for such pairs...

I joined the department of medicine at Yale as an assistant professor in 1977 and had a laboratory in the department of physiology. My initial studies and grants were for the characterization of Na+-glucose cotransport in renal brush border membrane vesicles, a research interest and experimental model system that I had brought from my research training with Bert Sacktor at the Gerontology Resea...
