Testing deviations from the inverse square law with a freely falling gravity gradiometer at Balloon altitudes
SummaryWe discuss a null experiment to search for the fifth force at ranges around 10 km. It is proposed to use a three-axis gravity gradiometer to measure the trace of the Earth gravity tensor fromExpand

The effect of dead time on the power spectral density estimates of discrete time series
Abstract A study of the bias introduced on the power spectral density (PSD) of discrete time series by the presence of a fixed dead time in the detection system has been performed. Both the cases ofExpand
