A Transiting "51 Peg-like" Planet.
Doppler measurements from Keck exhibit a sinusoidal periodicity in the velocities of the G0 dwarf HD 209458, having a semiamplitude of 81 m s-1 and a period of 3.5239 days, which is indicative of aExpand
Sub-Saturn Planetary Candidates of HD 16141 and HD 46375.
TLDR
Precision Doppler measurements from the Keck High-Resolution Echelle Spectrograph reveal periodic Keplerian velocity variations in the stars HD 16141 and HD 46375, which contribute to the rising planet mass function toward lower masses. Expand

TLDR
The use of AMS is limited by the expensive accelerator technology required, but there are several attempts to develop compact AMS spectrometers at low (< or = 0.5 MV) terminal voltages. Expand
Multiple-rotor-cycle QPASS pulse sequences: separation of quadrupolar spinning sidebands with an application to 139La NMR
TLDR
A new version of the QPASS sequence is demonstrated here and is shown to alleviate many problems associated with the original sequence, and to allow for use of weaker RF field strengths that excite only the central quadrupolar transition. Expand
Measurement of internuclear distances in solid-state NMR by a background-filtered REDOR experiment
A background-filtered version of the rotational-echo double resonance (REDOR) experiment is demonstrated. The experiment combines a traditional REDOR pulse sequence with a double-cross-polarizationExpand

TLDR
Two 1H-detected one-dimensional gradient enhanced experiments and corresponding reference experiments are proposed for the measurement of heteronuclear long-range nJCH coupling constants in organic molecules and are shown to provide accurate and efficient measurements of coupling constants that would be difficult or time-consuming to measure by other techniques.

  • 7 June 2010
Synthetic aperture techniques are widely used and well-established in both, radar and ultrasound imaging systems, because of the similar wave physics. In this contribution, synthetic aperture radarExpand
The 17th Symposium on Measuring Techniques in Transonic and Supersonic Flow in Cascades and Turbomachines
The present paper describes a technique for using recessed-mounted miniature pressure transducers to measure unsteady pressures in turbomachine related test facilities. Rather than embeddingExpand
An Experimental Study of a Bubble-Driven Liquid Metal Flow Under the Influence of a Rotating Magnetic Field
In this study we investigate the flow structure in a liquid metal cylinder while a bubble-driven flow is superposed with a rotating magnetic field(RMF).Argon gas is injected through a nozzle into aExpand
LIBS and Raman Spectroscopy for Planetary in-situ Exploration
Laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy have a high potential for in-situ geochemical and mineralogical analyses for planetary exploration, in particular when combined.Expand
