Background Cardiovascular Magnetic Resonance (CMR) is recognised as the gold standard technique for the assessment of cardiovascular function in adults. In children, image quality is dependent on compliance with motion control and breath-hold instructions. Inability to maintain repeated breath-holds in a consistent phase of respiration can result in respiratory misregistration errors. There is ...

Playing a central role in the information-systems research community’s discourse on design science has been the concept of the “IT artifact.” We pose the alternative concept of the “IS artifact.” We “unpack” what has been called the “IT artifact” into a separate “information artifact” and “technology artifact” that, together with a “social artifact,” interact to form the “IS artifact.” We illus...

background: the electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful. objective: removing electrocardiogram contamination from electromyogram signals. methods: in this paper, the clean electromyogram signal, electrocardiogram artifact and...
