A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs. A scalar measure of the…
FORMULATION AND ESTIMATION OF STOCHASTIC FRONTIER PRODUCTION FUNCTION MODELS
- A. U.S
- Mathematics
- 2001
Previous studies of the so-called frontier production function have not utilized an adequate characterization of the disturbance term for such a model. In this paper we provide an appropriate…
Type IIA Moduli Stabilization
- A. U.S
- Mathematics
- 2005
We demonstrate that flux compactifications of type IIA string theory can classically stabilize all geometric moduli. For a particular orientifold background, we explicitly construct an infinite…
Assortative Matching and Search
- A. U.S
- Economics
- 2000
In Becker’s (1973) neoclassical marriage market model, matching is positively assortative if types are complements: i.e. match output f(x, y) is supermodular in x and y. We reprise this famous result…
D-brane Field Theory on Compact Spaces
- A. U.S
- Mathematics, Physics
- 1996
We consider Dirichlet p-branes in type II string theory on a space which has been toroidally compactified in d dimensions. We give an explicit construction of the field theory description of this…
Predictability , Complexity , and Learning
- A. U.S
- Computer Science
- 2002
It is argued that the divergent part of Ipred(T), the mutual information between the past and the future of a time series, provides the unique measure for the complexity of dynamics underlying aTime series.
WAVES: THE RADIO AND PLASMA WAVE INVESTIGATION ON THE WIND SPACECRAFT
The WAVES investigation on the WIND spacecraft will provide comprehensive measurements of the radio and plasma wave phenomena which occur in Geospace. Analyses of these measurements, in coordination…
Geochemical Perspectives on Coral Mineralization
Corals open an exceptional window into many phenomena of geological, geochemical, climatic, and paleontological interest. From the Paleozoic to the present, corals provide some of the finest…
Level truncation and the tachyon in open bosonic string field theory
- A. U.S
- Physics
- 2000
The tachyonic instability of the open bosonic string is analyzed using the level truncation approach to string field theory. We have calculated all terms in the cubic action of the string field…
