Second harmonic generation (SHG),
a nonlinear optical tool, was used to
characterize DNA bound through a
chemical linker to the flat surface of a
hemispherical lens. Contact angle
measurements were used to guarantee
that the chemical linker did not hydrolyze
under experimental conditions. SHG
experiments followed the effects of salt...
This presentation contains information on the keynote paper "Health Monitoring of Early Age Concrete". The presentation was delivered by Surendra P. Shah at CONSEC'04 in Seoul, Korea on June 30, 2004.
At the heart of nonlinear optimization methods lies the solution of linear systems of equations. As the size of the problem increases, it is imperative to use iterative methods, such as the conjugate gradient algorithm, to solve these linear systems. In the context of constrained optimization, it has proved to...
Substrate-mediated delivery involves the immobilization of DNA, complexed with nonviral vectors, to a biomaterial or surface that supports cell adhesion. Cells cultured on the substrate are exposed to elevated DNA concentrations within the local microenvironment, which enhances transfection. As surface properties are critical to this delivery approach, self-assembled monolayers (SAMs)...
Should the government subsidize entry to promote competition? In theory, free entry does not guarantee the socially optimum number of entrants. In differentiated product markets, free entry can result either in excessive or insufficient entry. Quantifying this inefficiency and identifying the optimal subsidy level require an empirical framework that combines...
Autism was originally described as involving an apparent lack of motivation for social interaction. Social motivation has not figured prominently in subsequent theorizing regarding this disorder. Instead, theory of mind deficits have taken center stage as a theory of autism. This is surprising because evidence of social motivation deficits appear...
The measurement of weak adhesive energies has previously been difficult to obtain. To measure these energies, I designed a technique that uses the combined sensitivities of both a quartz crystal resonator and the inflation of an elastomeric polymer membrane. The surfaces of the quartz crystal and/or the membrane are modified...

This final report contains information on years 6-7-8 (2004-2007) of TEA-21 funded projects designated A487, W420, and A212. The report was submitted by Morris E. Fine and Semyon Vaynman in 2007.
PilD is an enzyme that processes prepilins that are part of the type II protein secretion apparatus and the type IV piliation machinery. Using a <em>Legionella pneumophila pilDlacZ</em> fusion strain to measure transcription, we observed a 20% increase in beta-galactosidase levels at 30°C vs. 37°C. At 25°C and 17°C vs....
