Abstract: A pulsed magnetic particle imaging system includes a magnetic field generating system that includes at least one magnet, the magnetic field generating system providing a spatially structured magnetic field within an observation region of the magnetic particle imaging system such that the spatially structured magnetic field will have a field-free region (FFR) for an object under observation having a magnetic nanoparticle tracer distribution therein. The pulsed magnetic particle imaging system also includes a pulsed excitation system arranged proximate the observation region, the pulsed excitation system includes an electromagnet and a pulse sequence generator electrically connected to the electromagnet to provide an excitation waveform to the electromagnet, wherein the electromagnet when provided with the excitation waveform generates an excitation magnetic field within the observation region to induce an excitation signal therefrom by at least one of shifting a location or condition of the FFR.

Abstract: A method determines and displays the geographic location of a plurality of articles. At least one geographic location of each of the plurality of articles is determined. The determining includes extracting entities of the article, determining which extracted entities are places entities, determining a geographic location of each of the places entities, and attributing the geographic location of each of the places entities with the article. A map is created. The map comprises a geographic map. A plurality of clickable markers are displayed on the map. The clickable markers correspond to the geographic locations of the plurality of articles. Attributes of the markers may be modified. When a marker is clicked on, a web page may be instantly published, the web page comprising articles having a geographic location of the marker that was clicked on.
