MR elastography of liver fibrosis: preliminary results comparing spin-echo and echo-planar imaging

The purpose of this study was to prospectively compare the performance of magnetic resonance (MR) elastography using echo-planar and spin-echo imaging for staging of hepatic fibrosis. Twenty-four patients who had liver biopsy for suspicion of chronic liver ...

CMOS realization of two-dimensional mixed analog-digital Hamming distance discriminator circuits for real-time imaging applications

Alexandre Schmid, Yusuf Leblebici, Stéphane Badel

The architecture of an integrated Hamming artificial neural network, and its use as a versatile signal/image processing circuit is presented. The circuit operation relies oil the charge-based processing of sum-of-products terms, complemented with digital p ...

Tandem Mass Spectrometry Protein Identification on a PC Grid

Markus Müller, Dominique Zosso, Ruedi Aebersold

We present a method to grid-enable tandem mass spectrometry protein identification. The implemented parallelization strategy embeds the open-source x!tandem tool in a grid-enabled workflow. This allows rapid analysis of largescale mass spectrometry experim ...

Three challenges in route choice modeling

Michel Bierlaire, Emma Frejinger

Route choice models play an important role in many aspects of transportation analysis, when the usual shortest path paradigm is too unrealistic (real-time information systems, traffic simulation, etc.). Developing operationnal route choice models involves ...

Rotation correlation maps

Touradj Ebrahimi

A correlation map shows the correlation between an image region and another image computed at the neighbourhood of each point of the second image. Most cross-correlation techniques fail when the viewpoint rotation grows over a certain value, usually around ...

Quantification of tremor and bradykinesia in Parkinson’s disease using a novel ambulatory monitoring system

Kamiar Aminian, Arash Salarian

An ambulatory system for quantification of tremor and bradykinesia in patients with Parkinson's disease (PD) is presented. To record movements of the upper extremities, a sensing units which included miniature gyroscopes, has been fixed to each of the fore ...

High spatial resolution picosecond cathodoluminescence of InGaN quantum wells

Nicolas Grandjean, Jean-François Carlin, Benoît Marie Joseph Deveaud, Eric Feltin, Andrea Crottini, Jean-Daniel Ganière

The authors have studied InxGa1-xN/GaN (x approximate to 15%) quantum wells (QWs) using atomic force microscopy (AFM) and picosecond time resolved cathodoluminescence (pTRCL) measurements. They observed a contrast inversion between monochromatic CL maps co ...

Physico-mechanical properties of Ultra High Performance Fibre Reinforced Concrete

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

The effect of different curing temperatures (from 20 to 40 °C) on the compressive strength and hydration of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) have been investigated between 3 and 28 days, using the loss on ignition test (LOI) and th ...

The dynamics of mergers and acquisitions

Erwan Morellec

This paper presents a dynamic model of takeovers based on the stock market valuations of merging firms. The model incorporates competition and imperfect information and determines the terms and timing of takeovers by solving option exercise games between b ...
