A comparison of vertical velocities measured from specular and nonspecular echoes by a VHF radar [PDF]

open access: yes, 1986
For a number of years, there have been doubts about the accuracy of vertical wind velocities measured with quasi-specular reflections from mesosphere-stratosphere-troposphere (MST) radar.

Distortion of Infall Regions in Redshift Space-I

open access: yes, 2013
We show that spherical infall models (SIMs) can better describe some galaxy clusters in redshift slice space than in traditional axially-convolved projection space.

Wave-like warp propagation in circumbinary discs I. Analytic theory and numerical simulations

open access: yes, 2013
In this paper we analyse the propagation of warps in protostellar circumbinary discs. We use these systems as a test environment in which to study warp propagation in the bending-wave regime, with the addition of an external torque due to the binary ...

Upper limits on stray force noise for LISA

open access: yes, 2003
We have developed a torsion pendulum facility for LISA gravitational reference sensor ground testing that allows us to put significant upper limits on residual stray forces exerted by LISA-like position sensors on a representative test mass and to ...

On the feasibility of tilt test outcome early prediction using ECG and pressure parameters

open access: yesEURASIP Journal on Advances in Signal Processing, 2011
The tilt test is a valuable clinical tool for vasovagal syncope (VVS) diagnostic, and its early prediction from simple ECG and blood pressure-based parameters has widely been studied in the literature.

Transfer of autocollimator calibration for use with scanning gantry profilometers for accurate determination of surface slope and curvature of state of the art x ray mirrors [PDF]

open access: yes, 2019
X ray optics, desired for beamlines at free electron laser and diffraction limited storage ring x ray light sources, must have almost perfect surfaces, capable of delivering light to experiments without significant degradation of brightness and coherence.
