Bridging Tribology and Microrheology of Thin Films
An enhanced version of the flexure-based microgap rheometer (FMR) is described which enables rheological measurements in steady state shearing flows of bulk fluid samples of PDMS with an absolute gap separation between the shearing surfaces of 100 nm – 100 μm. Alignment of the shearing surfaces to a parallelism better then 10 rad allows us to reliably measure shear stresses at shear rates up to...
متن کاملX-ray scattering in the vorticity direction and rheometry from confined fluids.
An X-ray flexure-based microgap rheometer (X-FMR) has been designed for combining rheology and in situ small-angle X-ray scattering from the vorticity plane. The gap distance can be varied continuously from 500 μm down to several μm, which provides the unique possibility to generate a strong confinement for many complex fluids. A singular advantage of this setup is the possibility to directly p...
متن کاملPreprocessing of fMR Datasets
When studying complex cognitive tasks using functional magnetic resonance (fMR) imaging one often encounters weak signal responses. These weak responses are corrupted by noise and artifacts of various sources. Preprocessing of the raw data before the application of test statistics helps to extract the signal and thus can vastly improve signal detection. We discuss artifact sources and algorithm...
متن کاملfMR-adaptation and the bilingual brain.
fMR-Adaptation, where a pair of identical stimuli elicits a smaller neural response than a pair of dissimilar stimuli has been extensively used to study object identification and classification as well as memory. Thus far this technique has found limited application in evaluating brain areas sensitive to meaning, language and control of language production. These studies are reviewed together w...
