We establish selection of critical pulled fronts in invasion processes as predicted by the marginal stability conjecture. Our result shows convergence to a front with logarithmic shift for open sets steep initial data, including one-sided compactly supported conditions. rely on robust, conceptual assumptions, namely existence and spectral traveling at linear spreading speed demonstrate that ass...

Objective: The aim of this study was to use ultrasonography for the diagnosis and confirmation of Pulled Elbow treatment.Methods: This descriptive cross-sectional study initiated in 2014 and continued until 2015. We used simple sampling method and recruited 60 samples among patients aged 4 months to 6 years. The apparatus used in this study was an ultraso...

We used ultrasonography in ten children with pulled elbow to compare measurements of the radiocapitellar distance (RCD) on the affected and the unaffected sides. Similar measurements were made in a group of ten age-matched normal children. The mean RCD in pronation of the affected and normal sides in the patients with pulled elbows was 7.2 mm +/- 0.7 and 3.8 mm +/- 0.5, respectively (p < 0.0001...
