Modern retrieval test collections are built through a process called pooling in which only a sample of the entire document set is judged for each topic. The
Calcium phosphate cement (CPC) sets in-situ with intimate contact with neighboring bone and forms apatite with excellent osteoconductivity and bone-replacement

We describe a dielectric resonator-based measurement method for determining the electrical conductivity of carbon nanotubes and nanowires at microwave to
Tomographic studies of submicrometer samples in materials science using electron microscopy have been inhibited by diffraction effects. In the present work, we
In the twenty-first century, most high-performance concretes, and many other ordinary concretes, are now based on blended cements that contain silica fume, slag

We report the experimental demonstration of site-selective RF addressing of atoms with sub-wavelength resolution in a spin-dependent optical lattice of double
We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications to the classical
When diluted in some solvents, surfactants and block copolymers self-assemble into micelles or vesicles of about 10-100 nm in size. There is a great deal of
An approach to the analysis of key comparisons data is proposed using a model taken from meta-analysis metrology. Under the assumption of Gaussian distributions
