We have investigated stress evolution in dilute nitride GaAs1−xNx alloy films grown by plasma-assisted molecular-beam epitaxy. For coherently strained films sx,2.5% d, a comparison of stresses measured via in situ wafer curvature measurements, with those determined from x-ray rocking curves using a linear interpolation of lattice parameter and elastic constants, suggests significant bowing of t...
We report two sibs, the ninth and tenth cases of a distinctive familial skeletal dysplasia. Designated kyphomelic dysplasia, the condition is a short limbed dwarfism characterised by very short angulated femora, variable bowing of other long bones, irregular, flared metaphyses, restricted joint mobility, a small thorax and short trunk, a normal cranium and psychomotor development, and a tendenc...
BACKGROUND Little information is available regarding the prevalence of laryngeal pathology in adults. PURPOSE To estimate the prevalence of occult laryngeal pathology in a community-based cohort of adults over 40 years of age. METHODS One hundred consecutive volunteers over age 40 with no history of voice disorders were enrolled. All completed a self-administered laryngeal symptom questionn...
This paper presents a virtual violin for real-time performances consisting of two modules: a violin spectral model and a control interface. The interface is composed by a sensing bow and a tube with drawn strings in substitution of a real violin. The spectral model is driven by the bowing controls captured with the control interface and it is able to predict spectral envelopes of the sound corr...
Light-emitting diodes (LEDs) become an attractive alternative to conventional light sources due to high efficiency and long lifetime. However, different material properties between GaN and sapphire cause several problems such as high defect density in GaN, serious wafer bowing, particularly in large-area wafers, and poor light extraction of GaN-based LEDs. Here, we suggest a new growth strategy...
Background: In a total knee arthroplasty surgery the goal is to produce 90 degree angle between the knee articular lobe and the mechanical femoral line. Most orthopedic surgeons usually utilize a 5 to 7 degree for distal femoral cutting angle. In this study we will aim at clearing this question, that whether the” five-seven degree” distal femoral cutting angle supposed to be an equable spectrum...
Brown Pelicans (Pelecanus occidentalis) plunge dive into water to capture fish with highly distensible pouches. During prey capture, the pouch may expand to hold 11 L of water and the mandibular rami may bow from a resting position of 5 cm to over 15 cm. We compared mineralization of two bending regions of the mandible with a nonbending region, and examined cross-sectional morphology to determi...
BACKGROUND Femoral bowing plane (FBP) is the unattended subject in the literature. More over the femoral shaft with its bowing is neglected in established anteversion determination methods. There is limited information about the relationship between FBP and anteversion. Thus we focused on this subject and hypothesized that there could be an adaptation of FBP to anteversion. MATERIALS AND METH...
Epitaxial transparent oxide NixMg1-xO (0 ≤ x ≤ 1) thin films were grown on MgO(100) substrates by pulsed laser deposition. High-resolution synchrotron X-ray diffraction and high-resolution transmission electron microscopy analysis indicate that the thin films are compositionally and structurally homogeneous, forming a completely miscible solid solution. Nevertheless, the composition dependence ...
