Laser-Induced Fluorescence Emission (L.I.F.E.) as Novel Non-Invasive Tool for In-Situ Measurements of Biomarkers in Cryospheric Habitats Klemens Weisleitner1,2, Lars Hunger3, Christoph Kohstall4, Albert Frisch5, Michael C. Storrie-Lombardi6, Birgit Sattler1,2 1Institute of Ecology, University of Innsbruck, 2Austrian Polar Research Institute, University of Vienna, 3BrainLinks-BrainTools, Bernstein Center Freiburg, 4Atom Science, Kasevich Lab, Stanford University, 5Institute of Experimental Physics, University of Innsbruck, 6Department of Physics, Extraterrestrial Vehicle Instruments Laboratory, Harvey Mudd College Carbon fluxes in the cryosphere are hardly assessed yet but are crucial regarding climate change. Here we show a novel prototype device that captures the phototrophic potential in supraglacial environments based on laser-induced fluorescence emission (L.I.F.E.) technology offering high spectral and spatial resolution data under in situ conditions.
Force and Position Control in Humans - The Role of Augmented Feedback Benedikt Lauber1,2, Martin Keller2, Christian Leukel1,3, Albert Gollhofer1, Wolfgang Taube2 1Department of Sport Science, University of Freiburg, 2Department of Medicine, Movement and Sport Science, University of Fribourg, 3Bernsteincenter Freiburg Controlling an identical movement with position or force feedback results in different neural activation and motor behavior. This protocol describes how to investigate behavioral changes by looking at neuromuscular fatigue and how to evaluate motor cortical (inhibitory) activity using subthreshold TMS with respect to the interpretation of augmented feedback.
