    Quantum scattering from disordered surfaces (1991)

    Notes: A projected continuum formulation for time-independent quantum scattering from a continuum of channels is presented and applied to atomic scattering from disordered surfaces. Projecting out the channel continua gives rise to explicitly constructed optical potentials for the coherently diffracted scattering amplitudes, while the continuum diffuse scattering contribution is obtained in terms of these wave functions. Numerical application is made to atomic scattering from weakly corrugated disordered surfaces, for which a truncated set of coupled equations can be used within which the theory is shown to be unitary. The occurrence of a new phenomenon of disorder-induced sticking on rigid surfaces is demonstrated and comparison with phonon-induced sticking is made. These new disorder-induced sticking processes are shown to have very different energy dependence than phonon-induced sticking, with strong resonant sticking and oscillatory behavior seen at low incident energies.

    Chemical shift correlation spectroscopy in rotating solids: Radio frequency-driven dipolar recoupling and longitudinal exchange (1992)

    Notes: We present a new method of performing chemical shift correlation spectroscopy in solids with magic angle spinning (MAS). Its key feature is a longitudinal mixing period of π pulses that recouples the dipolar interaction. We discuss experimental results for triply-13C-labeled alanine and a theory combining MAS and π pulses.

    Strain and electronic interactions in InAs/GaAs quantum dot multilayers for 1300 nm emission (2002)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 91 (2002), S. 1365-1370

    Notes: We have investigated the emission properties of low-growth-rate InAs/GaAs self-assembled quantum-dot multilayer samples with spacer layers of different thicknesses. For two layers with the same InAs coverage and a spacer of 40 nm, emission from the two layers is shown to be at different wavelengths. This is discussed in terms of local strain and surface undulation caused by the first layer influencing the growth of the second layer. We show that by annealing the surface before the growth of each subsequent layer this effect can be avoided for spacers of 40 nm and above. Furthermore, it is shown by collecting photoluminescence over a limited area of an N-layer sample, grown with surface annealing, that this sample exhibits a maximum modal gain N times that of a single layer. For spacers below 10 nm, only one emission peak is observed. However, we show that the observation of a single peak is due, in this case, to tunneling between adjacent layers, and that the maximum modal gain at 1300 nm of such electronically coupled layers is comparable to that of a single layer. © 2002 American Institute of Physics.

    Self-reported long-term outcomes of hysterectomy (1991)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 98 (1991), S. 0 
    Details
    ISSN: 1471-0528
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Objectives— –To investigate women's perceptions of and satisfaction with the long-term outcomes from a hysterectomy performed between 2 and 10 years ago and to determine whether satisfaction is related to demographic factors, factors associated with the hysterectomy, and the number or type of perceived benefits and problems associated with the hysterectomy.Design— Retrospective survey by telephone interview and postal questionnaire of 236 women who had a hysterectomy between 2 and 10 years ago.Setting— Women who had had a hysterectomy were identified from a community survey in the Hunter Region of NSW, Australia.Subjects— Two hundred and thirty-six women who self-reported having had a hysterectomy between 2 and 10 years ago.Main outcome measures— Perceived benefits resulting from the hysterectomy; perceived physical and psychological problems caused by the hysterectomy; satisfaction with care.Results— Relief from heavy bleeding was the most frequent benefit (57%) and the most important benefit (32%). Most of the women reported improvements in symptoms experienced before hysterectomy but more than half the women had symptoms which they believed had been worsened or caused by the hysterectomy. Despite this, high levels of satisfaction with the operation were reported.Conclusion— The results highlight the need to examine more closely decision-making about treatment for menstrual symptoms such as heavy bleeding.

    Above-threshold longitudinal profiling of carrier nonpinning and spatial modulation in asymmetric cavity lasers (1998)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 83 (1998), S. 3784-3788

    Notes: Longitudinal variations of photon and carrier density along the length of a Fabry–Perot quantum well laser are simulated and compared to experimental carrier density measurements performed using a side spontaneous emission scanning technique. Both simulation and measurement demonstrate the existence of carrier nonpinning along the cavity of the laser, with increasing carrier density from the low reflectivity facet toward the high reflectivity facet. Measured carrier densities increased monotonically above their threshold value with injection current, at all points along the laser, seemingly contradicting the condition of net round-trip gain pinning at threshold. This behavior is attributed to current spreading into the low-gain regions aside the active region causing a current-dependent increase in spontaneous emission, and thus an apparent increase in measured active region carrier density. Periodic spatial modulation of the carrier density profile, consistent with the hypothesis of beam steering induced by beating and locked lateral modes, was also observed. © 1998 American Institute of Physics.

    BACTERIURIA IN PREGNANCY (1973)
    Oxford, UK : Blackwell Publishing Ltd

    Details

    Topics: Medicine
    Notes: Bacteriuria (defined as the presence of organisms on culture in a specimen of urine obtained by suprapubic bladder aspiration) was found in 132 (6.6 per cent) out of 2000 pregnant women attending an antenatal clinic. Bacteriuria was more frequent in the lower than the upper social classes, but was not related to the patient's age, parity or ethnic group. In 5 out of 18 patients with bacterial counts of lo4 or less per ml., spontaneous clearance of bacteriuria occurred. Of 186 patients who had further samples of urine examined during pregnancy after having a sterile urine on booking, only one developed a persistent infection de novo. Seventy-nine of the original 2000 patients were seen in a second pregnancy. Twelve of these patients were infected (and treated) in the first pregnancy and 5 of them had bacteriuria in the second pregnancy; the other 67 patients had sterile urine in the first pregnancy and one of these had bacteriuria in a second pregnancy. Thirty per cent of the patients with bacteriuria had symptoms which were usually associated with urinary infection when they were first seen, but so did 25 per cent of the uninfected control patients. Neither bacteriuria nor recurrence of infection after treatment could be diagnosed by symptoms. Only 34 per cent of patients with symptoms after treatment had recurrent infection, and of those who did have recurrent infection 27 per cent had symptoms.

    Fabrication of highly ordered metallic nanowire arrays by electrodeposition (2001)

    Notes: Highly ordered hexagonal arrays of parallel metallic nanowires (Ni, Bi) with diameters of about 50 nm and lengths up to 50 μm were synthesized by electrodeposition. Hexagonal-close-packed nanochannel anodized aluminum oxide film was used as the deposition template. The deposition was performed in an organic bath of dimethylsulfoxide with metal chloride as the electrolyte. A high degree of ordering and uniformity in these arrays can be obtained with this technique by fine-tuning the electrodeposition parameters. Moreover, an unprecedentedly high level of uniformity and control of the wire length was achieved. The arrays are unique platforms for explorations of collective behavior in coupled mesoscopic systems, and are useful for applications in high-density data storage, field emission displays, and sensors. © 2001 American Institute of Physics.
