    Vallecular cyst: an uncommon cause of stridor in newborn infants (2000)
    Springer
    European journal of pediatrics 159 (2000), S. 79-81 
    Details

    Topics: Medicine
    Notes: Abstract Vallecular cyst, a rare but generally benign lesion in the larynx, may cause stridor and even life-threatening airway obstruction in early infancy. We retrospectively studied 14 cases of newborn infants with vallecular cyst. There was no gender predilection and most cases were full-term and appropriate for gestational age. The clinical presentations included stridor, chest wall retraction, feeding difficulties and failure to thrive. Laryngomalacia was the most common associated anomaly. Flexible laryngoscopy was sufficient for diagnosing the vallecular cyst and larygmalacia. Maintenance of airway patency, nutritional support, and de-roofing of the cyst were the mainstays of management. Conclusion Vallecular cyst should be included in the differential diagnosis of stridor in newborn infants. Respiratory and feeding difficulties in these patients can be dramatically improved after appropriate surgical removal of the cyst.

    ZnSTe-based Schottky barrier ultraviolet detectors with nanosecond response time (1998)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 73 (1998), S. 2251-2253

    Topics: Physics
    Notes: ZnSTe-based Schottky barrier photovoltaic detector arrays were fabricated on GaP(100) using a two-step molecular beam epitaxy growth approach. These detectors exhibit visible blind and ultraviolet (UV) sensitive response with a peak UV responsivity of 0.13 A/W and 1.2×106 V/W at 320 nm. The built-in potential of these detectors was determined to be 1.7 V. The temporal photocurrent response of a 400×400 μm2 detector was measured to be 1.2 ns, limited apparently by the resistance-capacitance (rc) constant of the detector structure. © 1998 American Institute of Physics.

    One- and two-photon-excited time-resolved photoluminescence investigations of bulk and surface recombination dynamics in ZnSe (1998)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 83 (1998), S. 4773-4776

    ISSN: 1089-7550

    Topics: Physics
    Notes: Measurements of femtosecond time-resolved one- and two-photon-excited photoluminescence of bulk ZnSe enable us to distinguish the surface and bulk contributions to recombination dynamics. A photoluminescence lifetime of several nanoseconds or longer is measured for the bulk. A fast relaxation component with a decay time constant τT of a few tens of picoseconds observed in one-photon-pumped time-resolved spectra is identified as the result of diffusion and rapid surface recombination. A one-dimensional model taking into account surface nonradiative recombination and carrier diffusion is able to describe the observed behavior. The temperature dependence of τT shows good agreement with the theory. At room temperature, a surface recombination velocity S=5.8×105 cm s−1 and a diffusion constant D=10 cm2 s−1 are found using this model. © 1998 American Institute of Physics.

    EFFECTS OF CORTISOL ON BLOOD PRESSURE AND SALT PREFERENCE IN NORMAL HUMANS (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical and experimental pharmacology and physiology 20 (1993), S. 0 
    Details

    Topics: Medicine
    Notes: 1. Adrenocorticotrophic hormone (ACTH) and corticosteroids stimulate salt appetite in laboratory animals. The hypothesis tested was that cortisol administration increases salt preference in humans.2. Sodium taste studies (detection and recognition thresholds, taste intensity and preference tests) were conducted before, during and after cortisol administration (200 mg/day for 5 days) in normal men on a free diet.3. Cortisol significantly increased systolic blood pressure (SBP), 113 ± 3–130±4 mmHg, P 〈 0.05; diastolic blood pressure (DBP), 65±3–81±2 mmHg, P 〈 0.05; mean arterial pressure (MAP), 81± 2–97± 3 mmHg, P 〈 0.05; and bodyweight, 72.9±3.0–75.4±3.3 kg, P 〈 0.05.4. Salt detection and recognition thresholds, taste intensity and preference for sodium chloride were unchanged following cortisol.

    Studies of resonant and preresonant femtosecond degenerate four-wave mixing in unoriented conducting polymers (1991)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Degenerate four-wave mixing with femtosecond time resolution is used to measure the magnitude and transient response of the third-order nonlinear optical susceptibility χ(3) (ω;ω,−ω,ω) at 620 nm in nonoriented conducting polymers including polydiacetylene, 〈m1;38p〉polyacetylene, polyaniline, polydiethynylsilane, polythiophene, and polythiophene derivatives. 〈m1;40p〉Resonant and nonresonant excitations influence the magnitude and transient response of χ(3). 〈m1;39p〉The electronic response is instantaneous for preresonant excitation, but for resonant excitation it 〈m1;38p〉has ultrafast and slow components which illustrate photoexcitation dynamics. The 〈m1;38p〉magnitude of χ(3) for all of the polymers is in the range from 10−10 to 5×10−8 esu depending on the energy difference between the laser excitation and the polymer absorption maximum.

    Molecular-beam-epitaxy-grown ZnMgS ultraviolet photodetectors (2001)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Epitaxial growth of Zn1−xMgxS alloy thin films on GaP(100) substrates was carried out using the molecular-beam-epitaxy technique. In situ reflection high-energy electron diffraction studies show that the alloys can be grown with a stable zinc-blende structure up to x around 30%. For x〉30%, a structural transition will occur at a critical thickness which is sensitively dependent on the x composition. A near-band-edge peak with a full width at half maximum of about 10 nm was observed in room-temperature photoluminescence measurements made on as-grown alloy thin films. Several Zn1−xMgxS-based Schottky barrier photodetectors were fabricated. Room-temperature photoresponse measurements were performed on these detectors and abrupt long-wavelength cutoffs covering 325, 305, 295, and 270 nm were achieved for devices with Mg composition of 16%, 44%, 57%, and 75%, respectively. The response curve of the Zn0.43Mg0.57S device offers a close match to the erythemal action spectrum that describes human skin sensitivity to UV radiation. © 2001 American Institute of Physics.

    Observation of in-plane optical anisotropy of spin-cast rigid-rod electroluminescent polymer films (2000)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 76 (2000), S. 1416-1418

    Notes: Transmittance difference spectroscopy has been applied to study the optical properties of spin-cast rigid-rod polymer films. Significant in-plane optical anisotropy is observed for both the real and the imaginary parts of the transmittance of the poly(2,5-pyridine diyl) films. This in-plane optical anisotropy is a result of the partial alignment of the polymer chains, oriented radially outward from the center of the film, during the spin casting process. This observation has important implications for emissive polymer devices, particularly for devices sensitive to polarization direction and those using waveguide confinement where relatively long propagation distance within the films are required. © 2000 American Institute of Physics.
