We consider this a strong motivation for further observations and for enhanced efforts to significantly improve our theoretical understanding of the accretion process in binary X-ray pulsars. We speculate about the physics behind the long-term decay and its inversion, a possible cyclic behavior, and correlation","authors_text":"D. Klochkov, F. F\\\"urst, F. Harrison, J. Wilms, R.E.
