We report experimental results on the low-temperature uptake of HCl on H(2)O ice (ice). HCl was deposited on the surface at greater than monolayer amounts at 85 K, and the ice substrate was heated. The temperature dependence of the HCl vapor pressure from this phase was measured from 110 to 150 K, with the nucleation of a bulk hydrate phase observed at 150(More)
Genome annotations are accumulating rapidly and depend heavily on automated annotation systems. Many genome centers offer annotation systems but no one has compared their output in a systematic way to determine accuracy and inherent errors. Errors in the annotations are routinely deposited in databases such as NCBI and used to validate subsequent annotation(More)
We have developed a new thermodynamic theory of the quasiliquid layer, which has been shown to be effective in modeling the phenomenon in a number of molecular systems. Here we extend our analysis to H(2)O ice, which has obvious implications for environmental and atmospheric chemistry. In the model, the liquid layer exists in contact with an ice defined as(More)
NOTICE This technical report does not necessarily represent final EPA decisions or positions. It is intended to present technical analysis of issues using data which are currently available. The purpose in the release of such reports is to facilitate the exchange of technical information and to inform the public of technical developments which may form the(More)
In this contribution, we look at technology transfer in robotics. Generally, there is a delay between a science-push and a market-pull. In order of finding means to decrease this lag, we are going to look at the causes of this effect and at the means for improving technology transfer. For this purpose, we use a variety of data sources which shed light on(More)
Competition and oxidation of fatty acids spread at the air/water interface were investigated using surface-specific, broad-bandwidth, sum frequency generation spectroscopy. At the air/water interface, a monolayer of oleic acid replaced a monolayer of deuterated palmitic acid at equilibrium spreading pressure. Subsequent oxidation of the oleic acid monolayer(More)
Bone cements for vertebroplasty must have a much better radiocontrast level than cements for knee or hip arthroplasty. This is generally accomplished by adding a relatively large portion of BaSO(4), although this affects the physical-mechanical and biological properties of the cement. This prompted us to develop an alternative radiopaque cement, on the(More)
At work and at leisure people perform various visual search tasks, e.g. they search for a particular icon in software tools, on Web sites or on mobile phones. With an increasing number of items, visual search becomes difficult. Recently, it has been suggested that the so-called con-textual cueing effect, which is known from psychological experiments, can be(More)
— In this contribution the authors examine robotics research itself. We look at the data which the European funded ECHORD project (European Clearing House for Open Robotics Development) generated. The project began in January 2009 with the ambitious goal of bringing together European robotics manufacturers with the European research institutions and it(More)
