Robust gamma-aminobutyric acid and energy metabolism measurements by proton and phosphorus magnetic resonance spectroscopy and fingerprinting

Magnetic resonance spectroscopy (MRS) is the only technique that can detect endogenous metabolites directly and non-invasively in vivo. It allows to identify different metabolites and analyze the dynamic neurochemical processes in the brain, skeletal muscl ...

Validating atlas-based lesion disconnectomics in multiple sclerosis: A retrospective multi-centric study

Tobias Kober, Bénédicte Marie Maréchal, Reto Meuli, Jonas Richiardi, Mario Joao Fartaria de Oliveira

The translational potential of MR-based connectivity modelling is limited by the need for advanced diffusion imaging, which is not part of clinical protocols for many diseases. In addition, where diffusion data is available, brain connectivity analyses rel ...

Optimization of SEM-EDS to determine the C-A-S-H composition in matured cement paste samples

Karen Scrivener, John Espen Rossen

Microanalysis of characteristic X-rays in the SEM is a powerful method to assess the chemical composition of phases in cement pastes, in particular the calcium silicate hydrate containing aluminium (C-A-S-H). Nevertheless, many variables may influence the ...

Intonation Modelling for Speech Synthesis and Emphasis Preservation

Pierre-Edouard Jean Charles Honnet

Speech-to-speech translation is a framework which recognises speech in an input language, translates it to a target language and synthesises speech in this target language. In such a system, variations in the speech signal which are inherent to natural hum ...

Gentle quantitative measurement of helium density in nanobubbles in silicon by spectrum imaging

Cécile Hébert, Duncan Thomas Lindsay Alexander, Guillaume Lucas

We propose an original method for the determination of the physical properties of nanometer sized helium bubbles using spectrum imaging in an energy-filtered transmission electron microscope. Helium bubbles synthesized by high fluence implantation and ther ...

Optimized MEGA-SPECIAL for in vivo glutamine detection in the rat brain at 14.1 T

Rolf Gruetter, Cristina Ramona Cudalbu, Mélanie Craveiro

Glutamine has multiple roles in brain metabolism and its concentration can be altered in various pathological conditions. An accurate knowledge of its concentration is therefore highly desirable to monitor and study several brain disorders in vivo. However ...

Automated approach for rigorous light detection and ranging system calibration without preprocessing and strict terrain coverage requirements

Jan Skaloud

Light detection and ranging (LiDAR) has demonstrated its capabilities as a prominent technique for the direct acquisition of high density and accurate topographic information. To achieve the potential accuracy of such systems, a rigorous system calibration ...

Toward Reliable MR-Based Brain Structure Morphometry : Importance of Rigorous Quality Control

Bénédicte Marie Maréchal

Dementing neurodegenerative disorders have more and more prominent public health implications with the most frequent cause being the currently non reversible Alzheimer's Disease (AD). However, over the past 15 years, an abundant literature has demonstrated ...

A Dual Modifier-Adaptation Approach for Real-Time Optimization

Dominique Bonvin, Alejandro Gabriel Marchetti, Benoît Chachuat

For good performance in practice, real-time optimization schemes need to be able to deal with the inevitable plant-model mismatch problem. Unlike the two-step schemes combining parameter estimation and optimization, the modifier-adaptation approach does no ...

UECML: Unified Enterprise Competence Modelling Language

Rémy Glardon, Naoufel Cheikhrouhou, Grégoire Pepiot

This paper introduces the principles of a unifiedlanguage devoted to the area of competence-based enterprisemodelling. The language, named UECML, for UnifiedEnterpriseCompetenceModellingLanguage, is intended to provide a neutral interface to enterprisemode ...
