7-fs-pulses with 0.3 mJ are obtained after filamentation in argon and compression by double-chirped-mirrors. These pulses are used to generate high-order harmonics in a semi-infinite gas cell in different noble gases. Spectral broadening of high-order harmonics in xenon and argon is observed. In neon, an extended continuous cut-off region down to 10 nm (124 eV) is observed which is to the best ...

Introduction Arterial spin labeling is sensitive to contamination due to off-resonance effects of the RF label. While it has been argued that in PASL these effects are small compared to pulse profile effects [1], this assessment has to be re-evaluated in view of the advent of highly selective gradient-modulated adiabatic pulses such as FOCI [2], requiring several times more RF energy than the c...

BACKGROUND Frequent short sickness absences result in understaffing and interfere with work processes. We need more knowledge about factors associated with this type of absence. AIMS To investigate associations between the frequency of previous sickness absence and self-reported perceptions of health and work. METHODS Cross-sectional study of female hospital care workers in which health, wo...

This paper describes an on-off control scheme for minimum time maneuver of flexible spacecraft with vibration suppression during the slew. The method minimizes the maneuver time subject to constraints on residual vibration, sensitivity to modeling errors, rest-to-rest slew distance, and transient vibration amplitude. Furthermore, a solution is sought in the form of a plausible train of pulses, ...

At FAIR 3 GeV antiprotons are to be accumulated in the RESR up to an intensity of 10. If the CR is equipped for full performance, every 5 s a batch of 10 antiprotons will be transferred to the RESR. The antiprotons are precooled to a momentum spread of 0.1% and an emittance of 5 mm mrad. As an option, azimuthal separation of injected and stacked beams with barrier buckets was studied. The proce...
