STUDY DESIGN Positional magnetic resonance imaging (MRI) study of control subjects. OBJECTIVES To determine dimensional changes in the lumbar dural sac as a function of posture, and to establish changes between the supine, erect and seated positions. SUMMARY OF BACKGROUND DATA Studies using computerized tomography and MRI were done to determine the(More)
STUDY DESIGN The length of the cervical cord in healthy volunteers was measured in the supine and erect position using positional magnetic resonance imaging (MRI). OBJECTIVE To assess the relationship between the length of the cervical cord and cervical posture in healthy volunteers. SUMMARY OF BACKGROUND DATA A number of detailed descriptions of the(More)
Hydrogenation of iron nanoparticles was performed both computationally and experimentally where previously chemically-bonded iron hydride is considered to be unachievable under ordinary conditions. Density functional theory (DFT) calculations predict that hydrogenated iron nanoparticles are stabilized on a single-layer graphene/Cu substrate. Experimentally,(More)
In this paper, we propose a novel wearable sensor device for the measurement of the head orientation and relative position against the body trunk in real-time. It is known that in natural walking, human locomotion is preceded by changes in head orientation [1, 2, 3] and the walking direction can therefore be predicted by observing the head orientation. We(More)
