This paper describes a first attempt to map UMLS concepts to pictographs as a resource for translation systems for the medical domain. An evaluation of pictographs from two freely available sets shows that for many concepts no pictograph could be found and that word-based lookup is inadequate for this task.

The effects of external pressure on a high-performing dysprosocenium single-molecule magnet are investigated using a combination of X-ray diffraction, magnetometry and theoretical calculations. The effective energy barrier () decreases from 1300 cm at ambient pressure to 1125 cm at 3 GPa. Our results indicate that compression < 1.

Single-ion magnets based on lanthanide ions in pseudo- symmetry have gained much attention in recent years as they are reported to possess a large blocking temperature and a large barrier for magnetization reversal. Magneto-structural correlations reveal that the axial O-Ln-O angle is an important parameter to control the barrier, and while it can be fine-tuned by chemical modification, an alternative would be to utilize hydrostatic pressure. Herein, we report the crystal structures and static magnetic properties of two air-stable isostructural lanthanide SIMs under applied pressures.

In classical posturography the standing position has been evaluated by recording the postural sway on a force-plate and measuring some parameters such as surface and velocity (Platform or P-recording). The postural sway not only results in forces exerted on the support surface by the feet, but the head also participates in the movements of this postural sway. For recording of the head movements (H-recording), a lightbulb is placed on top of the head and the described light-path is recorded by a TV camera.

A practical clinical view of the reliability of the data obtained in the several steps of the examination procedure is discussed to obtain an objective basis for the selection of patients with provoked vertigo (benign paroxysmal positioning vertigo [BPPV]) in view of treatment of this type of vertigo by rehabilitation therapy. Clinical experience supports the concept that the diagnosis has to be based not only upon a typical history, but also upon the presence of a reproducible vertigo and paroxysmal positional nystagmus (ppn). Such a ppn can be reproduced not only as a "classic" nystagmus by the Dix-Hallpike maneuver, but also as a positional nystagmus and vertigo during electronystagmographic recording in the position tests and in the vestibular habituation training (VHT)-test battery (a battery of 19 maneuvers applied for defining the adequate exercises in the rehabilitation treatment of BPPV).
