Fabrication of Polymer-Based Micro Devices: Formulation and Study of the Paste

Peter Ryser, Thomas Maeder, Nathalie Sophie Adeline Serra, Olivier Gentsch

We investigate in the present work the fabrication of polymer-based micro-fluidic and micro-mechanical devices using sacrificial, resistive/conductive pastes, through a screen-printing process. An organic sacrificial paste is first screen-printed onto a su ...

Multichannel Compressed Sensing via Source Separation for Hyperspectral Images

Pierre Vandergheynst, Mohammad Golbabaee

This paper describes a novel framework for compressive sampling of multichannel signals that are highly correlated across the channels. In this work, we assume few number of independent sources are generating the multichannel observations based on a linear ...

A Class of Transformations that Polarize Binary-Input Memory less Channels

Satish Babu Korada, Eren Sasoglu

A generalization of Arikan's polar code construction using transformations of the form G(circle times n) where G is an l x l matrix is considered. Necessary and sufficient conditions are given for these transformations to ensure channel polarization. It is ...

Microfluidic system based on thermoexpandable polymer for on chip blood coagulation testing

Philippe Renaud, Lynda Metref, Raphaël Goetschmann, François Bianchi

This paper describes a simple system for the actuation of a biological fluid through micro-channels with a thermoactivated polymer actuator. This system is of interest for the development of single-use diagnostic test-strips since the actuation of the samp ...

Integrated microfluidic system for non-invasive electrophysiological measurements on Xenopus oocytes

Elodie Deborah Dahan

We developed a new non-invasive integrated microsystem for electrophysiological measurements on Xenopus laevis oocytes. The Xenopus oocyte is a well-known expression system for various kinds of ion channels that are of potential interest for drug screening ...

Atoms of all channels, unite! Average case analysis of multi-channel sparse recovery using greedy algorithms

Pierre Vandergheynst, Rémi Gribonval, Karin Schnass

This paper provides new results on computing simultaneous sparse approximations of multichannel signals over redundant dictionaries using two greedy algorithms. The first one, p-thresholding, selects the S atoms that have the largest

Continuous-flow separation of cells in a lab-on-a-chip using "liquid electrodes" and multiple-frequency dielectrophoresis

Nicolas Demierre

This thesis reports on the integration of continuous-flow cell separation method for lab-on-a-chip applications. Cell separation methods are widely used in biology to prepare samples prior to analysis. There is a need for a highly sensitive separation meth ...

Characterization of a microfluidic dispensing system for localised stimulation of cellular networks

Nico de Rooij

We present a 3-D microfluidic device designed for localized drug delivery to cellular networks. The device features a flow cell comprising a main channel for nutrient delivery as well as multiple channels for drug delivery. This device is one key component ...

Variable length coding over an unknown channel

Emre Telatar, Aslan Tchamkerten

Burnashev in 1976 gave an exact expression for the reliability function of a discrete memoryless channel (DMC) with noiseless feedback. A coding scheme that achieves this exponent needs, in general, to know the statistics of the channel. Suppose now that t ...
