Reprogramming activity of NANOGP8, a NANOG family member widely expressed in cancer

NANOG is a key transcription factor for pluripotency in embryonic stem cells. The analysis of NANOG in human cells is confounded by the presence of multiple and highly similar paralogs. In particular, there ar...

Energy barriers for vortex nucleation in dipolar condensates

We consider singly-quantized vortex states in a condensate of ⁵²Cr atoms in a pancake trap. We obtain the vortex solutions by numerically solving the Gross-Pitaevskii equation in the rotating frame with no furthe...

Vortex rings in toroidal Bose-Einstein condensates

We study vortex ring solutions of the Gross-Pitaevskii equation for Bose-Einstein condensates confined in toroidal traps. Analogously to the Feynman-Onsager ansatz for a single vortex line, we assume a condens...
