    Notes: The sonic band-gap structures of 12-fold symmetry quasicrystals consisting of rigid cylinders in air are investigated by using the multiple scattering method. Large full gaps are found in this system owing to its high symmetry. At filling fractions between 0.2 and 0.4, this 12-fold square–triangle tiling is much better for the realization of sonic band gaps than the square or triangular lattice. This makes the 12-fold quasicrystal a promising structure for acoustic-wave band-gap materials. © 2002 American Institute of Physics.

    Notes: We study the shape of distribution F(G) for the conductance G between a point on the surface of a metal–insulator nanocomposite film and the conducting substrate. Random resistor networks with both metallic and tunneling bonds included are used to model nanocomposite films. Our simulation results show explicitly that the shape of F(G) is determined mainly by the connectivity of metal particles and the maximum tunneling distance in the composite. By applying our results to the available experimental data on granular NiFe–SiO2, we find important implications for the understanding of microscopic conduction mechanisms near the metal–insulator transition. © 2000 American Institute of Physics.

    Notes: By using a perturbative approach, we propose a simple, systematic, and efficient method to engineer acoustic band gaps. A gap can be enlarged or reduced by altering the microstructure according to the field-energy distributions of the Bloch states at the band edges as well as their derivatives. Due to the structure of the acoustic wave equation, the engineering of acoustic band gaps is much more efficient than that of photonic band gaps. The validity of the proposed method is supported by multiple-scattering calculations. Our method makes the acoustic band gap "designable." © 2001 American Institute of Physics.

    Notes: Abstract In the photosynthetic bacterium Rhodopseudomonas capsulata, NH 4 + switch-off of nitrogenase activity can be mimicked by its analog, methylamine. Like NH 4 + , methylamine appeared to require processing by glutamine synthetase (GS) before it was effective; γ-glutamylmethylamide was shown to be the product of this reaction. Evidence that this glutamine analog functioned directly to initiate nitrogenase inactivation was suggested first by the fact that it was a poor substrate for glutamate synthase (i.e., it was not further metabolized by this pathway) and secondly, azaserine which blocks the transfer of the glutamine amide group had no effect on CH3NH 3 + (or NH 4 + ) switch-off. These observations are taken as preliminary evidence to suggest that when NH 4 + inhibits nitrogenase activity, inactivation is initiated by glutamine itself, and not a molecule derived from it. Finally, evidence was presented that R. capsulata would use CH3NH 3 + as a nitrogen substrate, but lag periods and generation times increased with subsequent passages.
