چکیده
Quantum tunneling was observed in the decay of metastable spin domains in gaseous Bose-Einstein condensates. A mean-field description of the tunneling was developed and compared with measurement. The tunneling rates are a sensitive probe of the boundary between spin domains, and indicate a spin structure which is prohibited in the bulk fluid. These experiments were performed with optically trapped F 1 spinor Bose-Einstein condensates of sodium.

A systematic review on reminder systems in physical therapy
Background: The main goal of physical therapy is to help the patient gain a better health status. Several studies have investigated the use of reminders to prevent such failures on the patients’ side. This article presents a systematic review of the literature concerning reminders in physical therapy. Methods: Databases were searched until May 2017 and literatures were found from April 1...
