X-ray absorption near edge structure (XANES) spectroscopy at the sulfur K-edge was applied to probe the speciation of sulfur of metabolically different sulfur-accumulating bacteria in situ. Fitting the spectra using a least-square fitting routine XANES reveals at least three different forms of sulfur in bacterial sulfur globules. Cyclooctasulfur dominates(More)
Two anaerobic thermophilic bacteria, designated strains JW/SL824 and JW/SL-NZ826(T), were isolated from an acidic volcanic steam outlet on White Island, New Zealand. Cells were rod-shaped, spore-forming, motile and Gram-stain negative, but contained Gram-type positive cell wall. Strain JW/SL-NZ826(T) utilized various carbohydrates including xylose and(More)
We present a virtual reality framework and assistive tool for design practices for new medical environments, grounded on human visual perception, attention and action. This includes an interactive visualization of shared electronic patient records, previously acquired with a remote tablet device, in a virtual environment incorporating hand tracking, eye(More)
We present State Hopper, an interactive multimedia application that uses Linked Open Data to generate a map-based educational game. A prototype of the system using Europe as map was implemented in a student project. Goal of the game is to move from country to country by learning facts about the countries like population, GDP, size, and others. Each movement(More)
In this demo paper we describe how a digital pen and a humanoid robot companion can improve the social communication of a dementia patient. We propose the use of NAO, a humanoid robot, as a companion to the dementia patient in order to continuously monitor his or her activities and provide cognitive assistance in daily life situations. For example, patients(More)
To improve reporting practices in breast imaging, we allow the radiologist to write structured reports with a pen on a smartphone. In this way, we provide a knowledge acquisition system for digital mammography. In this domain, printed documents cannot be easily replaced by computer systems because they contain free-form sketches and textual annotations ,(More)
