Gradient-based numerical optimization of complex engineering designs o ers the promise of rapidly producing better designs. However, such methods generally
We have developed a large lensless line-focus wideband ultrasonic transducer which can be used to probe solid materials through water. With conventional

We describe a simplified scheme for quantum logic with a collection of laser-cooled trapped atomic ions. Building on the scheme of Cirac and Zoller, we show how
The time and polarization resolved ultrasonic technique which we previously developed has been demon-strated to simultaneously provide measurements of the wave
We have developed a time-and-polarization-resolved acoustic microscopy technique to determine material properties of solids immersed in water. At the heart of
A simple, inexpensive, optically isolated current-to-voltage converter circuit has been developed for the measurement of bipolar currents in the range of 10 pA

Using scanning tunneling microscopy, we observe the alloying of Cr with an Fe(001) substrate for various coverages at two temperatures. At low Cr coverage, the
