We show that the recently proposed integer-forcing linear receiver provides an attractive approach to the problem of mitigating external interference in MIMO channels. The integer-forcing receiver proceeds by first decoding a set of full rank integer linea ...
The year 2011 having been proclaimed by UNESCO and IUPAP “International Year of Chemistry”, it seems fitting to have a close look at a physical chemistry instrument, the Polaristrobometer, an early form of polarimeter/saccharimeter, at its inventor, the Sw ...
In this paper we present a tool to annotate paper documents with vocal comments. This tool does not require specially processed documents, and allows natural and simple interactions: sticking a note to add a comment, and place an object on it to listen to ...
This thesis explores the properties of the transmission of light through subwavelength slits in metal films. Theoretical and experimental studies on the transmission through slits in metals are presented. In addition, the potential use of these slits for d ...
Ultra high-resolution measurements of amplitude and phase fields emerging from fine period amplitude gratings are presented and discussed. In the axial direction periodically repeated features are found, whose origins are the Talbot effect within the Fresn ...
The experiment performed by Bonneville and Escaig, designed for the direct measurement of the activation parameters of cross-slip, has been repeated. A denser initial dislocation forest density is obtained with a higher predeformation stress compared with ...
A study of the coherence and wavefront properties of a pseudo-channel-cut monochromator in comparison with a double-crystal monochromator is presented. Using a double-grating interferometer designed for the hard X-ray regime, the complex coherence factor w ...
It is theoretically shown that by superimposing diffraction-free solutions of the Helmholtz equation, one can construct localized diffraction-free beams that pass through predetermined points on subwavelength distances. These beams are based on the phenome ...
We have observed the interferometric suspension of a free-falling Bose-Einstein condensate periodically submitted to multiple-order diffraction by a vertical 1D standing wave. This scheme permits simultaneously the compensation of gravity and coherent spli ...
We report a high-throughput method for the fabrication of metallic nanogap arrays with high-accuracy over large areas. This method, based on shadow evaporation and interference lithography, achieves sub-10 nm gap sizes with a high accuracy of 61.5 nm. Cont ...
