Minimal models are developed to examine the origin of large negative thermal expansion in underconstrained systems.
It has been shown that the number of users that can be supported by frequency-hopped, spread-spectrum multiple-access systems can be increased greatly by using multiuser demodulation and iterative
Methods of adaptive soft combining and channel decoding are developed to combat the effects of multipath fading and nonuniform interference channels, with particular application to hybrid in-band o

The ground state of the two-dimensional electron gas near nu=1 is investigated by inelastic light scattering measurements carried down to very low temperatures.
We present a detailed magnetothermal study of Pr0.7Ca0.3MnO3, a perovskite manganite in which an insulator-metal transition can be driven by magnetic field, but also by pressure, visible light, x r
Raman spectra of Pb{[}(Mg1/3Nb2/3)(1-x),Ti-x]O-3 and Pb{[}(Zn1/3Nb2/3)(1-x),Ti-x]O-3 solid solutions display transverse optic vibration modes that soften with composition and reveal interactions be
Recent advances in x-ray laser research have significantly increased the possibilities for x-ray laser applications.
We have developed a cryo scanning transmission X-ray microscope which uses soft X-rays from the National Synchrotron Light Source.
Soft, conformable electrical contacts provide efficient, noninvasive probes for the transport properties of chemically and mechanically fragile, ultrathin organic semiconducting films.
