FORMULATION AND ESTIMATION OF STOCHASTIC FRONTIER PRODUCTION FUNCTION MODELS
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 appropriateExpand

Predictability , Complexity , and Learning
We deŽne predictive information Ipred(T) as the mutual information between the past and the future of a time series. Three qualitatively different behaviors are found in the limit of largeExpand

D-brane Field Theory on Compact Spaces
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 thisExpand

Level truncation and the tachyon in open bosonic string field theory
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 fieldExpand

Type IIA Moduli Stabilization
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 infiniteExpand

Multiple Dp-branes in Weak Background Fields
We find the terms in the nonabelian world-volume action of a system of many Dp-branes which describe the leading coupling to all type II supergravity background fields. These results are found byExpand

Estimators of Fractal Dimension : Assessing the Roughness of Time Series and Spatial Data
Abstract The fractal or Hausdorff dimension is a measure of roughness (or smoothness) for time series and spatial data. The graph of a smooth, differentiable surface indexed in Rd has topological andExpand

Curved Mesh Generation and Mesh Refinement using Lagrangian Solid Mechanics
We propose a method for generating well-shaped curved unstructured meshes using a nonlinear elasticity analogy. The geometry of the domain to be meshed is represented as an elastic solid. TheExpand
