  • The Lorenz-Krishnamurthy slow manifold 

    Fowler, A. C.; Kember, G. (1996-05/15)
    The authors scale the five-mode model introduced by Lorenz and Krishnamurthy and show how explicit solutions may be obtained in the limit of small Rossby number by using the method of multiple scales. They thus obtain a ...

  • 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 ...
  • "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 ...
  • 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 ...
  • 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)
    Theoretical investigations, modeling and design of a Bragg mirror (photonic crystal structure) in the CdTe-based material system are presented. It is shown that, in addition to the third-order nonlinearity (Kerr-like ...
  • Mechanism of smart baroreception in the aortic arch 

    Kember, G. C.; Armour, J. A.; Zamir, M. (American Physical Society, 2006)
    A mechanism is proposed by which the patch of baroreceptors along the inner curvature of the arch of the aorta can sense hemodynamic events occurring downstream from the aortic arch, in the periphery of the arterial tree. ...
