The significance of the Hansen Ideal space frame
No full textKnown and unknown properties of Hansen Ideal coordinates are summarized. It is shown that the ideal space frame is a general and necessary component of basic celestial mechanics and astrodynamics, as well as of any theory of motion. A typical consequence is the intimate correlation of the Hansen frame with the Lagrange constraint within the method of the variation of the parameters. The use of observations in the ideal frame may allow conclusions on the intergalactic fundamental coordinate system

Development of transparent microwell arrays for optical monitoring and dissection of microbial communities
No full textCitation: Halsted, M., Wilmoth, J. L., Briggs, P. A., Hansen, R. R., Briggs, D. P., Timm, A. C., & Retterer, S. T. (2016). Development of transparent microwell arrays for optical monitoring and dissection of microbial communities. Journal of Vacuum Science & Technology B, 34(6), 5. doi:10.1116/1.4962739Microbial communities are incredibly complex systems that dramatically and ubiquitously influence our lives. They help to shape our climate and environment, impact agriculture, drive business, and have a tremendous bearing on healthcare and physical security. Spatial confinement, as well as local variations in physical and chemical properties, affects development and interactions within microbial communities that occupy critical niches in the environment. Recent work has demonstrated the use of silicon based microwell arrays, combined with parylene lift-off techniques, to perform both deterministic and stochastic assembly of microbial communities en masse, enabling the high-throughput screening of microbial communities for their response to growth in confined environments under different conditions. The implementation of a transparent microwell array platform can expand and improve the imaging modalities that can be used to characterize these assembled communities. Here, the fabrication and characterization of a next generation transparent microwell array is described. The transparent arrays, comprised of SU-8 patterned on a glass coverslip, retain the ability to use parylene lift-off by integrating a low temperature atomic layer deposition of silicon dioxide into the fabrication process. This silicon dioxide layer prevents adhesion of the parylene material to the patterned SU-8, facilitating dry lift-off, and maintaining the ability to easily assemble microbial communities within the microwells. These transparent microwell arrays can screen numerous community compositions using continuous, high resolution, imaging. The utility of the design was successfully demonstrated through the stochastic seeding and imaging of green fluorescent protein expressing Escherichia coli using both fluorescence and brightfield microscopies.

The eclipse of the goal of zero inflation
No full textWilliam J. Barber's study of Alvin H. Hansen (1887-1975) emphasized the importance of the intellectual transformation that led to the "'Keynes-Hansen intellectual system that appeared to have compelling diagnostic and prescriptive power" (Barber 19X7. 205).1 Between 1936 and 1938, Hansen became a convert to Keynesian economics, and this led to the Hicks-Hansen IS-LM model. Subsequent authors (including Phillips in the 1950s) concluded that this approach, being an equilibrium model, did not capture the disequilibrium "essence" of Keynes (Lipsey 19X I, 547). The purpose of this article is to highlight a second intellectual transformation in Hansen's policy advocacy, and to suggest the possibility that, once again, Hansen contributed to a Keynesian economics that was in conflict with Keynes's stated position. I will also discuss a parallel transformation in the policy advocacy of Sumner H. Slichter ( 1892-1959), who was, like Hansen, a Harvard University professor
Covariate Augmented Dickey-Fuller Tests with R
No full textThis paper describes CADFtest, a R (R Development Core Team 2008) package for testing for the presence of a unit root in a time series using the Covariate Augmented Dickey-Fuller (CADF) test proposed in Hansen (1995). The procedures presented here are user friendly, allow fully automatic model specification, and allow computation of the asymptotic p-values of the test.unit root, stationary covariates, asymptotic p-values, R.
