OBJECTIVE To examine the interrater reliability and completion time of the Functional Assessment Measure, which is the Functional Independence Measure (FIM) plus additional items (FIM+FAM). DESIGN Interrater reliability study. SETTING Inpatient rehabilitation units of a postacute care brain injury rehabilitation program. PATIENTS A convenience sample(More)
We report the first results of the LISA Pathfinder in-flight experiment. The results demonstrate that two free-falling reference test masses, such as those needed for a space-based gravitational wave observatory like LISA, can be put in free fall with a relative acceleration noise with a square root of the power spectral density of 5.2±0.1  fm(More)
We report on residual-gas damping of the motion of a macroscopic test mass enclosed in a nearby housing in the molecular flow regime. The damping coefficient, and thus the associated thermal force noise, is found to increase significantly when the distance between the test mass and surrounding walls is smaller than the test mass itself. The effect has been(More)
We report on electrostatic measurements made on board the European Space Agency mission LISA Pathfinder. Detailed measurements of the charge-induced electrostatic forces exerted on free-falling test masses (TMs) inside the capacitive gravitational reference sensor are the first made in a relevant environment for a space-based gravitational wave detector.(More)
