Rational toral ranks in certain algebras

We calculate the rational toral ranks of two spaces whose cohomologies are isomorphic and note that rational toral rank is a rational homotopy invariant but not a cohomology invariant.

High-resolution simultaneous voltage and Ca2+ imaging.

Combining voltage and Ca(2+) imaging allows the correlation of electrical and chemical activity at sub-cellular level. Here we describe a novel apparatus designed to obtain simultaneous voltage and Ca(2+) measurements with single-trial resolution from sites as small as a few microns. These measurements can be obtained with negligible optical cross-talk between the two signals and negligible pho...

High-resolution digital resampling using vector rational filters

Lazhar Khriji Faouzi Alaya Cheikh Moncef Gabbouj Tampere University of Technology Signal Processing Laboratory P.O. Box 553 FIN-33101 Tampere Finland E-mail: [email protected] Abstract. Rational filters are extended to multichannel signal processing and applied to image interpolation. Two commonly used decimation schemes are considered: a rectangular grid and a quincunx grid. For each decimation...
