We have examined fast flexion movements of the human thumb and fast extension movements of the elbow over three different distances at a variety of speeds in order to elucidate the function of the antagonist muscle in these circumstances. All movements were of such a velocity that they showed the typical bi- or triphasic pattern of muscle activation in agonist and antagonist. Slower movements, ...

Population movements of 891 ethnic units in Europe over the past 4,200 years, and the correlations of these movements with modern genetic distances were investigated on a one-degree-square grid of the continent. There is significant spatial pattern in movements from sources, to targets, and overall. Patterns change significantly over time. Patterns of sources and targets differ significantly. M...

The temporal coupling between the transport and grasp components of prehension movements was investigated through two experiments. In Experiment 1, six normal subjects were required to reach and grasp each of three spheres located at three different distances (Blocked trials). In Experiment 2, a visual perturbation paradigm was used in which the location of the object to be reached and grasped ...

objective(s): salvia miltiorrhiza (sm) is a popular and classic herb in traditional chineses medicines. the objective is to confirm the effects of aqueous extract of s. miltiorrhiza (esm) and its main ingredient on the promotion of orthodontic tooth movement and healing of periodontal ligament in rat. materials and methods: male sprague-dawley rats (n= 150) were divided into five groups: model ...

This paper presents the study on the effect of view distance and movement scale on performance of haptic based teleoperation of a sandblasting robot in complex steel bridge maintenance environments. The operational performance, measured by the Index of Performance (IP), is defined based on the speed and the control accuracy of the manipulator. View distance (i.e. the distance between a display ...
