When performing non-enhanced time-of-flight MR angiography of the lower extremity arteries at 7 T with cardiac triggering, the acquisition time is a crucial consideration. Therefore, in previous studies, saturation RF pulses were applied only every second TR. In the axial source images a slight artifact with an appearance similar to aliasing could be observed. The purpose of this study was to i...
The main reason why people are directed to rehabilitation services after stroke-like neurological diseases bring individuals' daily abilities a normal level.

We describe volunteer computing games, a new paradigm for computing which merges volunteer computing and online casual games. In volunteer computing, the main goal is to harness the computational power of many users’ computers to solve a large computational problem. Unfortunately, participants in volunteer computing come from a very limited demographic—primarily middle-aged male computer expert...

Task selection, previously thought to operate only under conscious, voluntary control, can be activated by unconsciously-perceived stimuli. In most cases, such activation is observed for unconscious stimuli that closely resemble other conscious, task-relevant stimuli and hence may simply reflect perceptual activation of consciously established stimulus-task associations. However, other studies ...
Volunteer computing is a paradigm in which devices participating in a distributed environment share part of their resources to help others perform their activities. The effectiveness of this computing paradigm depends on the collaboration attitude adopted by the participating devices.
