    Background:Latest research demonstrates a significant improvement in stress-related symptoms in psychological disorders as a result of exercise training (ET). Controlled clinical trials further validate the significance of ET by demonstrating lower ...
  • Meirbekova, Rauan (2016-02)
    Current efficiency loss in aluminum electrolysis happens due to a variety of factors. One such factor is the presence of impurities. Concerns about impurities have been voiced since the quality of raw materials has declined and dry-scrubbers were ...
  • Sitek, Anna; Ţolea, Mugurel; Niţă, Marian; Serra, Llorenç; Gudmundsson, Vidar; Manolescu, Andrei (Springer Nature, 2017-01-10)
    We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the Coulomb repulsion allows the formation of in-gap states, i.e., ...
