  • Winter, Rudolf; Smith, I. H.; Jones, Aled R.; Greaves, G. N. (2005)
    The glass-forming reactions between sodium carbonate (Na2CO3) and silica (SiO2) have been investigated by 23Na, 29Si, and 13C magic-angle spinning (MAS) NMR spectroscopy. The multinuclear MAS NMR approach identifies and ...

  • Poolton, Nigel; Evans, D. A.; Hamilton, B.; Towlson, B. M. (2006-05)
    The design and use of a novel portable synchrotron end-station is described, that allows for the micro-imaging of X-ray absorption features of solids, via their luminescence emission. This mode of measurement is possible ...

  • Plakhov, A. Y.; Torres, D. (2005-06-01)
    The problem of minimum resistance is studied for a body moving with constant velocity in a rarefied medium of chaotically moving point particles in the Euclidean space . The distribution of the velocities of the particles ...

  • Gohm, Rolf (2010-04-01)
    We study a model of repeated interaction between quantum systems which can be thought of as a non-commutative Markov chain. It is shown that there exists an outgoing Cuntz scattering system associated to this model which ...
  • Kummerer, B.; Gohm, Rolf; Lang, T. (2006)
    We give a non-commutative generalization of classical symbolic coding in the presence of a synchronizing word. This is done by a scattering theoretical approach. Classically, the existence of a synchronizing word turns out ...

  • Title, Alan; Carolus, Thomas; Shine, Richard; Wolfson, C. Jacob; Nightingale, Richard; Schrijver, Carolus; Brown, Daniel; Alexander, David (2003)
    Recent observations from TRACE in the photospheric white light channel have shown sunspots that rotate up to 200° about their umbral centre over a period of 3-5 days. The corresponding loops in the coronal fan are often ...
  • Kellett, B.; Dunkin, S. K.; Grande, Manuel (2001)
    Mercury is the little known innermost terrestrial planet. A number of significant questions remain unanswered. We describe areas in which a compact imaging X-ray spectrometer could make a valuable contribution. It can ...

  • Noakes, T. C. Q.; Bailey, P.; Jenkins, Tudor; Hayton, D. J. (2002-06)
    Medium energy ion scattering, Fourier transform infrared spectroscopy and spectroscopic ellipsometry measurements have been performed on thermally grown SiO2 layers on 4H silicon carbide. The data suggest the presence of ...

    Let Ω be an exterior domain in It is shown that Ornstein-Uhlenbeck operators L generate C0-semigroups on Lp(Ω) for p ∈ (1, ∞) provided ∂Ω is smooth. The method presented also allows to determine the domain D(L) of L and ...

  • Brown, Daniel; Schrijver, Carolus (2000-06-27)
    The magnetic field in the outer solar atmosphere is frequently distorted by flares. In some cases, a fraction of the field exhibits a rapidly damped oscillation (Schrijver et al.; Aschwanden et al.). If this is a resonating ...
  • Winningham, D.; Grande, Manuel; Lundin, R.; Barabash, S. (2006)
    Auroras are caused by accelerated charged particles precipitating along magnetic field lines into a planetary atmosphere, the auroral brightness being roughly proportional to the precipitating particle energy flux. The ...
