Fast and high-resolution myelin water imaging: Accelerating multi-echo GRASE with CAIPIRINHA

Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, Erick Jorge Canales Rodriguez, Marco Pizzolato, Gian Franco Piredda, Reto Meuli, Alessandro Daducci

Purpose Although several MRI methods have been explored to achievein vivomyelin quantification, imaging the whole brain in clinically acceptable times and sufficiently high resolution remains challenging. To address this problem, this work investigates the ...

SPOKEN LANGUAGE IDENTIFICATION USING LANGUAGE BOTTLENECK FEATURES

Petr Motlicek, Wissem Allouchi

In this paper, we introduce a novel approach for Language Identification (LID). Two commonly used state-of-the-art methods based on UBM/GMM I-vector technique, combined with a back-end classifier, are first evaluated. The differential factor between these ...

Towards Understanding of Human Kinematic Coordination Patterns in Bimanual Fine Manipulation Tasks

Aude Billard, Kunpeng Yao, Anaïs Betsabeh Haget

Skills that require the collaboration of both arms are common in humans’ everyday activities, and the coordination of upper limbs is key to human bimanual dexterity. The Skill Acquisition in Humans and Robots (ERC) project aims at obtaining a better unders ...

NRStitcher: non-rigid stitching of terapixel-scale volumetric images

Anne Bonnin, Marco Stampanoni

A Summary: In modern microscopy, the field of view is often increased by obtaining an image mosaic, where multiple sub-images are taken side-by-side and combined post-acquisition. Mosaic imaging often leads to long imaging times that can increase the proba ...

Scalable Learning-Based Sampling Optimization for Compressive Dynamic MRI

Volkan Cevher, Ruud van Heeswijk, Baran Gözcü, Thomas Sanchez

Slow acquisition has been one of the historical problems in dynamic magnetic resonance imaging (dMRI), but the rise of compressed sensing (CS) has brought numerous algorithms that successfully achieve high acceleration rates. While CS proposes random sampl ...

An inverse optimization approach to understand human acquisition of kinematic coordination in bimanual fine manipulation tasks

Aude Billard, Kunpeng Yao

Tasks that require the cooperation of both hands and arms are common in human everyday life. Coordination helps to synchronize in space and temporally motion of the upper limbs. In fine bimanual tasks, coordination enables also to achieve higher degrees of ...

Line narrowing in H-1 NMR of powdered organic solids with TOP-CT-MAS experiments at ultra-fast MAS

David Lyndon Emsley, Brennan James Walder, Federico Maria Paruzzo

The residual broadening observed in H-1 spectra of rigid organic solids at natural abundance under 111 kHz magic angle spinning (MAS) is typically a few hundred Hertz. Here we show that refocusable and non-refocusable interactions contribute roughly equall ...

Analysis and Reduction of Large Errors in Rayleigh-based Distributed Sensor

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Li Zhang, Luis Costa

Commonly, the frequency shift of back-reflection spectra is the key parameter to measure quantitatively local temperature or strain changes in frequency-scanned Rayleigh-based distributed fiber sensors. Cross-correlation is the most common method to estima ...

Dynamic Learning in Markets: Pricing, Advertising, and Information Acquisition

Thomas Alois Weber

In the face of demand uncertainty, a monopolist can observe sales as a controlled reaction to its price and advertising so as to improve the choice of this marketing mix in the future. Furthermore, to upgrade its knowledge about demand the firm has the opt ...

Autonomous Exploration for Radioactive Hotspots Localization Taking Account of Sensor Limitations

Francesco Mondada, Hadi Ardiny, Stefan John Witwicki

Effective radioactive hotspot localization and detection is limited by sensor characteristics (i.e., the long acquisition time and poor angular resolution AR of a gamma camera) that significantly degrade the performance of autonomous exploration in terms o ...
