Dissecting the Angular Momentum of Dark Matter Halos
We want to test the current theory that the dark matter of a halo imparts its angular momentum on infalling gas, dust, and stars that ultimately forms the disks of galaxies. Under this model, the spin of...

Persistent Switch Design for MgB2 Superconducting Magnet
High quality MRI imaging requires that the main magnetic field remain temporally stable to within 0.1 ppm per hour, which is achieved by operating the main superconducting magnet in persistent current mode. After a power supply...

Can We Use Sound Perception to Identify Rupture Patterns in Earthquakes?
The processes by which earthquakes occur is poorly understood. In more detail, an earthquake results from the relative motion of blocks of crust, or pieces of tectonic plates, across a...
