Marvin, Ursula B., and Brian Mason, editors. Catalog of Antarctic Meteorites, 1977-1978. Smithsonian Contributions to the Earth Sciences, number 23, 50 pages, 39 figures, 2 tables, 1980.—During two expeditions to Antarctica (1976-77 and 1977-78), more than 300 pieces of meteorites were collected from a small area adjacent to the Allan Hills (77°S, 159°E) in Victoria Land. The 1977-78 meteorites...

George Rosen, M.D., Ph.D. (June 23, 1910-July 27, 1977).

Professor of the H...

• Review of vector fields and differential equations in Rn . Let X be a vector field on a nonempty open subset of Rn . An integral curve of X with initial condition p0 is a differentiable path c : (a,b) → Rn , defined on an open interval containing 0 such that c(0) = p0 and c ′(t ) = X (c(t )) for all t ∈ (a,b). Thus to the vector field X one associates a differential equation ṗ = X (p). A solu...

Lecture 7 Statistical Models January 27 , 1998 Lecturer

In previous lectures we have discussed using the general expectation maximization algorithm to find an optimal weight matrix that indicated the probability for finding a given symbol at a given location in a motif. The weight matrix model has two main limitations in its ability to describe a family of related sequences, protein or otherwise. First of all, the weight matrix only allows compariso...
