An intergrowth of mucovite and biotite from Mitchell Creek Mine, Upson County, Georgia, was studied with a high resolution transmission electron microscope. Atomic arrangements of the interface between muscovite and biotite have been derived, revealing far more complexity for the interface structure than that proposed previously based on optical and X-ray analysis (Gresens and Stensrud, l97l). ...

The interface design is one of the essential elements for building a coherent and consistent learning object. However, it is still believed that interface design relates only to providing an aesthetic appearance to the learning object. The interface should be seen as the action space where mediatic objects are presented for user interaction. In this paper we introduce a architecture for adaptab...

We present a time-dependent semiclassical transport model for coherent pure-state scattering with quantum barriers. The model is based on a complex-valued Liouville equation, with interface condition at quantum barriers using complex-valued scattering coefficients computed from the steady-state Schrödinger equation. By retaining the phase information at the barrier, this coherent model is adequ...

A new embedded-atom potential has been developed for Ni3Al by fitting to experimental and first-principles data. The potential describes lattice properties of Ni3Al, point defects, planar faults, as well as the c and c0 fields on the Ni–Al phase diagram. The potential is applied to calculate the energies of coherent Ni/Ni3Al interphase boundaries with three different crystallographic orientatio...

We report a direct determination of the specular scattering probability of acoustic phonons at a crystal boundary by observing the escape of incident coherent phonons from the coherent state during reflection. In the sub-THz frequency range where the phonon wavelength is much longer than the lattice constant, the acoustic phonon-interface interaction is found to agree well with the macroscopic ...

We demonstrate the coherent control and electrical readout of ionized phosphorus donor nuclear spins in (nat)Si. By combining time-programed optical excitation with coherent electron spin manipulation, we selectively ionize the donors depending on their nuclear spin state, exploiting a spin-dependent recombination process at the Si/SiO(2) interface, and find a nuclear spin coherence time of 18 ...

-Human discourse appears coherent when it refleets coherent human thought. However, computers do not necessarily store or process information in the same way that people do a.ud~ therefore, cannot rely on the structure of their reuouing for the structure of thehr dialogue,s. Instead, computer-generated conversation must rely on some other mechanism for its orgsaiisation. In this paper, we discu...
