  • Control of cardiac function and noise from a decaying power spectrum 

    Kember, G. C.; Armour, J. A.; Fenton, G. A.; Malhotra, A. (American Physical Society, 2004)
    The transduction capability of cardiac affected neurons situated to the heart to control cardiac function was described. It was observed that the through in situ cardiac afferent activity shows evidence of independent and ...
  • Vertical nanowire light-emitting diode 

    Konenkamp, R.; Word, Robert C.; Schlegel, C. (American Institute of Physics Inc, 2004)
    We report room-temperature, white-color electroluminescence in vertically oriented ZnO nanowires. Excitonic luminescence around 380 nm is observed as a shoulder on a broader defect-related band covering all of the visible ...
  • "Smart" baroreception along the aortic arch, with reference to essential hypertension 

    Kember, G. C.; Zamir, M.; Armour, J. A. (American Physical Society, 2004)
    An arterial model was used to show that the cumulative effects of wave reflections have a surprisingly pronounced effect on the pressure distribution in the root segment of the tree. Global arterial conditions play a role ...
  • Analysis of a rock slide stabilized with a toe-berm: A case study in British Columbia, Canada 

    Corkum, AG; Martin, CD (Elsevier, 2004)
    Practical experience has shown that slope movement can be controlled by the placement of a berm near the toe of the moving mass. During construction of the Revelstoke project (British Columbia, Canada), excavation of a ...
  • Two-dimensional metallo-dielectric photonic crystals embedded in anodic porous alumina for optical wavelengths 

    Takayama, O.; Cada, M. (AIP, 2004-08/23)
    A theoretical study is presented for hexagonal lattice metallic pillar photonic crystals in anodic porous alumina with a lattice constant of 500 nm. The objective of the investigation is to design a two-dimensional ...
  • Switching mirror in the CdTe-based photonic crystal 

    Cada, M. (AIP, 2005-07/04)

  • Mechanism of smart baroreception in the aortic arch 

    Kember, G. C.; Armour, J. A.; Zamir, M. (American Physical Society, 2006)
