straints, motion capture. In this paper, we present a technique for motion: the problem of adapting an animated motion from one character to another. Our focus is on adapting the motion of one articulated figure to another figure with identical structure but different segment lengths, although we use this as a step when considering less similar characters. Our method creates adaptations that pr...

Background Free-breathing whole heart coronary MRA uses diaphragm navigator to gate data acquisition, which suffers from the need for time-consuming and exquisite positioning, prolonged scan time due to low gating efficiency, and inaccuracy in motion detection. In this work, a respiratory motion correction scheme is proposed with an affine motion model for accurate estimation of respiratory mot...

Extraction of motion from visual input plays an important role in many visual tasks, such as separation of figure from ground and navigation through space. Several kinds of local motion signals have been distinguished based on mathematical and computational considerations (e.g., motion based on spatiotemporal correlation of luminance, and motion based on spatiotemporal correlation of flicker), ...

BACKGROUND Infarct size is a strong predictor of mortality and major adverse cardiovascular events after myocardial infarction. Acute reperfusion therapy limits infarct size and improves survival, but its use has been confined to patients with ST-segment-elevation myocardial infarction. The purpose of this study was to assess the relationship between echocardiographic parameters of left ventric...

a lot of researches have investigated the effects of topical cyclosporine a on the eye surface layers' diseases. by now the main limitation in cyclosporine application is the low permeation of the drug into the posterior segments of the eye. the aim of present study was to formulate high permeable dosage form can be beneficial in the topical treatment of the uveitis. to reach higher corneal dru...

STUDY DESIGN Descriptive study. OBJECTIVE The purpose of this study was to describe the segmental motion of the lumbar spine during a posterior-to-anterior (PA) mobilization procedure using dynamic magnetic resonance imaging and to propose a mechanism of the lumbar spine's motion as a result of a PA force to a lumbar spinous process. BACKGROUND Studies reporting kinematic descriptions of PA...

An alternative approach to lumbar fusion surgery is to restore motion to the diseased segment with a disc prosthesis. The goal of the disc prosthesis is to replace the diseased disc while preserving and/or restoring the motion at the operated spinal level. The purpose of this study was to determine the ability of the PRODISC® (Spine Solutions Inc., Paoli, PA) disc prosthesis to restore lumbar s...

We present results from differential Global Positioning System (GPS) surveys of seven alignment arrays and four continuous GPS sites along the creeping segment of the San Andreas fault. Surveys of four alignment arrays from the central creeping segment yield 33to 36-year average minimum slip rates of 21–26 mm/yr. These rates are consistent with previous alignment array surveys spanning a 10-yea...

BACKGROUND Posterior fixation alone may not be adequate to achieve and maintain burst fracture reduction. Adding screws in the fractured body may improve construct stiffness. This in vitro study evaluates the biomechanical effect of inserting pedicle screws in the fractured body compared with conventional short- and long-segment posterior fixation. METHODS Stable and unstable L2 burst fractur...

The snakes can adopt manifold gaits and its motion has the characteristics of catholicity, ground adaptability, scalability, stability and high efficiency. This motivates the designing of multi-link wheeled snake robot using the principal of differential friction and Active Cord Mechanism (ACM) to produce serpentine movement. This paper focuses on the designing of the motor controller using fre...
