We present a first principle investigation of the electronic structure and the band gap bowing parameter of zinc-blende AlxGa1−xN using both local density approximation and screened-exchange density functional method. The calculated sX-LDA band gaps for GaN and AlN are 95% and 90% of the experimentally observed values, respectively, while LDA underestimates the gaps to 62% and 70%. In contrast ...

BACKGROUND AND PURPOSE The lateral rectus-superior rectus band is an orbital connective tissue structure that has been implicated in a form of strabismus termed sagging eye syndrome. Our purpose was to define the normal MR imaging and CT appearance of this band in patients without strabismus. MATERIALS AND METHODS Orbital MR imaging and CT examinations in 100 consecutive patients without stra...

BACKGROUND We retrospectively investigated the prevalence of femoral anterior notching and risk factors after total knee arthroplasty (TKA) using an image-free navigation system. METHODS We retrospectively reviewed 148 consecutive TKAs in 130 patients beginning in July 2005. Seventy knees (62 patients) underwent conventional TKA, and 78 knees (68 patients) received navigated TKA. We investiga...

We present a framework for modeling right-hand gestures in bowed-string instrument playing, applied to violin. Nearly non-intrusive sensing techniques allow for accurate acquisition of relevant timbre-related bowing gesture parameter cues. We model the temporal contour of bow transversal velocity, bow pressing force, and bow-bridge distance as sequences of short segments, in particular Bézier c...

As a literary subgenre, epic poetry is characterized with specific features in terms of language which distinguishes it from other subgenres. The secondary layer meaning the distinguishing factor. In study, order to examine epic, analyzes story "Rostam and Sohrab" frequency variety meanings its relationship type epic. For this purpose, syntactic structure verbs at beginning stanza related are e...
