Magnetic particle imaging (MPI) shows promise for medical imaging, particularly in angiography of patients with chronic kidney disease. As the first biomedical imaging technique that truly depends on nanoscale materials properties, MPI requires highly optimized magnetic nanoparticle tracers to generate quality images. Until now, researchers have relied on(More)
The magnetic response of magnetic particle imaging (MPI) tracers varies with the slew rate of the applied magnetic field, as well as with the tracer's average magnetic core size. Currently, 25 kHz and 20 mT/μ0 drive fields are common in MPI, but lower field amplitudes may be necessary for patient safety in future designs. We studied how several different(More)

The nuclear reactors used by the U.S. Navy for submarine propulsion are currently fu-eled by highly enriched uranium (HEU), but HEU brings administrative and political challenges. This issue has been studied by the Navy before, and promising new fuel technology developments, combined with new motivations, warrant a fresh look at low enriched uranium (LEU).(More)
The Treaty on the Non-Proliferation of Nuclear Weapons creates a loophole that allows a non-nuclear-weapon country to avoid international safeguards governing fissile materials if it claims that the materials will be used for naval nuclear propulsion purposes. The United States ability to negotiate a closing of this loophole is hampered by the fact that its(More)
Western European belief in demonic possession as a cause of mental disorder has been traced through the medieval and early modern periods. Generally it appears that the range of disorders attributed to demonic possession has gradually narrowed. In any period, however, there seem to have been marked individual and cultural differences in outlook; some of(More)
