Abstract An algorithm is presented for the use of a dynamic level-shifting parameter in solving SCF equations of semiempirical quantum chemical calculations. The shift parameter is changed automatically in each iteration cycle in order to reduce computation time.

Emergency nurses’ activity levels across rotating shifts
Australasian Emergency Care, 2020Emergency nurses work consecutive, rotating shift patterns. However, how their occupational physical activity levels are associated between these shifts is unknown. This study aimed to examine the associations between emergency nurses' time spent in different activity levels across one shift and the following day's shift.Fifty emergency nurses (45 ...

Random Level-Shift Time Series Models, ARIMA Approximations, and Level-Shift Detection
Journal of Business & Economic Statistics, 1990The main purpose of this article is to assess the performance of autoregressive integrated moving average (ARIMA) models when occasional level shifts occur in the time series under study. A random level-shift time series model that allows the level of the process to change occasionally is introduced. Between two consecutive changes, the process behaves

Proton recoil and radiative level shifts
Physical Review Letters, 1987Proton mass corrections to the Lamb shift of hydrogen of order ..cap alpha..(Z..cap alpha..)/sup 5/m/sup 2//M are evaluated. These contributions are expected new terms beyond those given earlier for recoil effects to the self-energy of a bound electron in the external-field approximation. The new contribution of this order is -0.53 kHz, thus making the

Abstract A level shifting effect in relation to the coupling of degenerate electronic states with vibrations in crystals is discussed. In this effect a degenerate level interacting with the lattice-phonon spectrum is shifted without the removal of degeneracy. This phenomenon is compared with Jahn-Teller effect in which the degeneracy is statically or
