Moon Mineralogy Mapper spectroscopic observations are used to assess the mineralogy of five sites that have recently been proposed to include lunar dark mantle deposits (DMDs). Volcanic glasses have, for the first time, clearly been identified at the location of three of the proposed pyroclastic deposits. This is the first time that volcanic glasses have been identified at such a small scale on...
A ‘‘which-path’’ ~welcher Weg! measurement necessarily destroys the fringes in a double-slit interference experiment. We show that in all instances one may attribute this destruction to a disturbance of the particle’s momentum by an amount equal to at least p\/2d , where d is the slit separation, in accordance with the uncertainty principle. However, this momentum transfer need not be local; th...
This study examined whether the relationship between information-seeking and social uncertainty differed when information was sought about a specific individual (e.g. a new housemate) or a group (e.g. a group of new housemates). An online experiment recruited 488 first-year undergraduates in the weeks immediately before starting a new university. Four information-seeking strategies (Ramirez, Wa...
The SAPIEN 3 CE Mark Trial is a non-randomized, prospective, multicentred study designed to assess the safety and device success of the Edwards SAPIEN 3 valve and the Edwards Commander and Edwards Certitude delivery systems in patients with symptomatic, severe aortic stenosis who are indicated for surgical aortic valve replacement (SAVR). Initial enrollment consisted of 50 high-risk patients. T...
SUMMARY RNA loop regions are essential structural elements of RNA molecules influencing both their structural and functional properties. We developed RLooM, a web application for homology-based modeling of RNA loops utilizing template structures extracted from the PDB. RLooM allows the insertion and replacement of loop structures of a desired sequence into an existing RNA structure. Furthermore...
