This study examined the effects of bihemispheric and unihemispheric transcranial Direct Current Stimulation (tDCS) over the inferior frontal gyrus (IFG) on proactive control. Sixteen participants were randomized to receive (i) bihemispheric tDCS, with a 35cm2 anodal electrode of the right IFG and a 35cm2 cathode electrode of left IFG or (ii) unihemispheric tDCS, with a 35cm2 anodal electrode of...

Robotersysteme werden seit mehreren Jahren in verschiedenen chirurgischen Bereichen zur Unterstützung des Chirurgen eingesetzt. Die Mehrzahl dieser Systeme sind an eine spezielle Anwendung angepasste Systeme, was neben den erhöhten Anschaffungsund Betriebskosten eine Verbreitung solcher Systeme auf spezialisierte Zentren begrenzt. Nur die wenigsten Systeme konnten bislang ein sozioökonomisch ve...

Many studies have addressed corticomuscular coherence (CMC), but broad applications are limited by low coherence values and the variability across subjects and recordings. Here, we investigated how the use of high-density surface electromyography (HDsEMG) can improve the detection of CMC. Sixteen healthy subjects performed isometric contractions at six low-force levels using a pinch-grip, while...

The Montage Image Mosaic Engine was designed as a scalable toolkit, written in C for performance and portability across *nix platforms, that assembles FITS images into mosaics. The code is freely available and has been widely used in the astronomy and IT communities for research, product generation and for developing next-generation cyber-infrastructure. Recently, it has begun to finding applic...

We present a novel method to generate salient montages from unconstrained videos, by finding “montageable moments” and identifying the salient people and actions to depict in each montage. Our method addresses the need for generating concise visualizations from the increasingly large number of videos being captured from portable devices. Our main contributions are (1) the process of finding sal...

Scientific workflows have received considerable attention in Grid computing. This paper is concerned with the issue of scheduling scientific workflows and, by considering a commonly used astronomy workflow, Montage, investigates the impact of different strategies to schedule the workflow graph. Our experiments suggest that the rather regular and symmetric nature of the Montage graph allows rath...

We present a fully automated adaptive optics (AO) retinal image montaging algorithm using classic scale invariant feature transform with random sample consensus for outlier removal. Our approach is capable of using information from multiple AO modalities (confocal, split detection, and dark field) and can accurately detect discontinuities in the montage. The algorithm output is compared to manu...
