Thin films bonded to compliant substrates often develop wrinkles when subjected to an applied or inherent compressive stress. This paper presents a bilayer...
A Buckminsterfullerene ion beam has been applied to the depth profiling of an alternating pure Pt and pure Co multilayer. Quantitative depth profiling was...

DNA-wrapped single wall carbon nanotubes (SWNTs) with broad length distributions are shown to reduce the viability of IMR90 primary human lung fibroblast cells...
The random-effects model is a useful approach for meta-analysis of clinical studies. It explicitly accounts for the heterogeneity of studies through a...
A detailed first principles analysis of the transport properties of different magnetic electrode materials for MgO tunnel junctions is performed to elucidate...

The stress-strain behavior of rat pulmonary arteries was studied using a bubble inflation technique. To obtain mechanical properties, an analytical method to...
In a simulation experiment, we study the feasibility of coded source neutron transmission tomography for imaging water density in fuel cells at the NIST neutron...
This paper presents an approach for making inference on the mean and variance of a Gaussian distribution in the presence of resolution errors. The approach is...

We perform linear stability calculations for horizontal fluid bilayers that can undergo a phase transformation, taking into account both buoyancy effects and...
Three-electron kinetic energy and nuclear attraction integrals arising in Hylleraas-configuration interaction (Hy-CI) calculations are discussed. We show that...

Poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2-b]thiophene, PBTTT, is a semiconducting polymer that forms thin film transistors (TFTs) with high field effect...
We probed four closely spaced rovibrational water vapor absorption transitions near wavenumber = 7100 cm(^-1) using frequency-stabilized cavity ring-down...
