STUDY DESIGN A biomechanical and anatomic study with human cadaveric lumbar spine. OBJECTIVES The purpose of this study is to examine the morphologic changes in the intervertebral foramen during flexion, extension, lateral bending, and axial rotation of the lumbar spine and to correlate these changes with the flexibility of the spinal motion segments. SUMMARY OF BACKGROUND DATA Previous stu...

BACKGROUND Laboratory spinal biomechanical tests using human cadaveric or animal spines have limitations in terms of disease transmission, high sample variability, decay and fatigue during extended testing protocols. Therefore, a synthetic biomimetic spine model may be an acceptable substitute. The goal of current study is to evaluate the properties of a synthetic biomimetic spine model; also t...

This paper presents the participation of our group in the ImageCLEF 2012 Photo Annotation Task. Our approach is based on visual and textual features as we experiment with different strategies in order to extract the semantics inside an image. First, we construct a textual dictionary of tags using the most frequent words present in the user tag annotated images from the training data sets. A lin...

For the distribution characteristics in a slice of pathological cell image, the system transforms them into the characteristic vectores by quantization and clustering in HSV color model, it promotes the concerned isolated pixel color description into the color feature ralative to its neighborhood’s color histogram and color moments. By choosing appropriate neighborhood window size, it uses colo...

The transverse velocities of steadily rotating, non–axisymmetric patterns in flat galaxies may be determined by a purely kinematical method, using two dimensional maps of a tracer surface brightness and radial current density. The data–maps could be viewed as the zeroth and first velocity moments of the line–of–sight velocity distribution, which is the natural output of integral– field spectrog...
