Moment of inertia and dynamical rotational response of a supersolid dipolar gas [PDF]

open access: yesPhysical Review A, 2022
We show that the knowledge of the time dependent response of a trapped gas, subject to a sudden rotation of a confining harmonic potential, allows for the determination of the moment of inertia of dipolar supersolid configurations. While in the presence of one-dimensional arrays of droplets the frequency of the resulting scissors oscillation provides ...

Long-Term Response to Subtotal Colectomy in Colonic Inertia

open access: yesJournal of Gastrointestinal Surgery, 2002
The purpose of this study was to determine the long-term outcome of patients who had previously undergone subtotal colectomy for severe idiopathic constipation at the University of Florida between 1983 and 1987. In addition, we aimed to determine whether preoperative motility abnormalities of the upper gastrointestinal tract are more common among those
