In areas with complex topography, the static shifts caused by lateral variations in thickness and/or velocity of the near-surface layers will distort the continuity of seismic events. More seriously, it will introduce false structural anomalies. In this report, a static correction approach, which does not require estimation of the near-surface model, is developed based on the closure phase prin...

We assume that each valence quark in a nucleon is in a phenomenological modified harmonic oscillator potential of the form: ( l+yo) (ar +br+cr +dr ), where a, b, c and d are constants and ? is one of the Dirac matrices. Then by making use of a suitable ansatz, the Dirac equation has a very simple solution which is exact. We then have calculated the static properties of the nucleon in the ...

BACKGROUND A novel splint, the assisting ankle-foot orthoses (AFO), was developed to provide adjustable sustained stretching to improve conservative treatment for equinus deformities in children with cerebral palsy (CP). The treatment effect was validated by follow-up visits. METHODS This study involved subjects between 2 and 12 years old, including 28 CP children treated with splint-assisted...

UNLABELLED PET imaging of nonhuman primates (NHPs) requires correction of head motion if the subjects are scanned awake and their heads are unrestrained, because the NHPs move their heads faster and more frequently than human subjects. This work focuses on designing and validating 2 motion-correction algorithms for awake NHP brain PET imaging. METHODS Two motion-correction methods were implem...

In their everyday life, people interact with different objects, static as well as those in motion. However, dynamic acuity is rarely checked in medical examinations, even those preceding the issue of driving license. In order for driving to be safe, good eyesight or good correction with visual aids is imperative. Beside good eyesight, drivers also have to have good reflexes and short reaction s...

The main aim of this study was to determine the kinetic energy and momentum coefficients of a small trapezoidal irrigation canal. A laboratory setup with a cyclic flow of water was used. The flow cross section was divided into ten equal sections with nine verticals in between. Pitot static tube was used to measure static and stagnation pressure heads at 1, 2, 3, 4, 5, or 6 point on the vertical...

We compute the leading order perturbative correction to the static potential in N = 4 supersymmetric Yang-Mills theory. We show that the perturbative expansion contains infrared logarithms which, when resummed, become logarithms of the coupling constant. The resulting correction goes in the right direction to match the strong coupling behavior obtained from the AdS/CFT correspondence. We find t...
