The assumption of free will—the ability of an experimentalist to make random choices—is central to proving the indeterminism of quantum resources, the primary tool in quantum cryptography. Relaxing the assumption in a Bell test allows violation of the usual classical threshold by correlating the random number generators used to select measurements with the devices that perform them. In this pap...

In a recent paper [8], it was shown how tests for database application systems can be executed efficiently. The challenge was to control the state of the database during testing and to order the test runs in such a way that expensive reset operations that bring the database into the right state need to be executed as seldom as possible. This work extends that work so that test runs can be execu...

introduction as functional magnetic resonance imaging (fmri) is too expensive and time consuming, its frequent implementation is difficult. the aim of this study is to evaluate repeatability of detecting visual cortex activity in fmri. materials and methods in this study, 15 normal volunteers (10 female, 5 male; mean age±sd: 24.7±3.8 years) attended. functional magnetic resonance images were ob...
