چکیده
We have devised a way to trap atoms above a magnetic surface using the Zeeman effect. The method is generally applicable to any paramagnetic atom with hyperfine structure and results in very strong confinement and, hence, a high vibrational frequency perpendicular to the surface. This allows the atomic de Broglie wave to propagate as in a single-mode 2D waveguide. We show how atoms can be continuously and unidirectionally coupled with high efficiency into the lowest mode of the waveguide. This invention makes possible the study of weakly interacting gases in 2D. [S0031-9007(97)05101-6]

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...
