Data-Driven MRSI Spectral Localization Via Low-Rank Component Analysis

Dimitri Nestor Alice Van De Ville, Jeffrey Adam Kasten

Magnetic resonance spectroscopic imaging (MRSI) is a powerful tool capable of providing spatially localized maps of metabolite concentrations. Its utility, however, is often depreciated by spectral leakage artifacts resulting from low spatial resolution me ...

Model calibration of a geomechanical problem with efficient global optimization

Francesco Comola

Efficient Global Optimization (EGO) is an optimization strategy based on approximating functions, namely Gaussian process models. We show the application of this technique to a model calibration problem referred to a geomechanical application. By means of ...

Micro-fabricated Alkali Vapor Cells for Chip Scale Atomic Clocks Sealed at Low Temperature with Thin-Film Metallic Bonding

Nico de Rooij, Danick Briand, Yves Pétremand, Rahel Strässle

Micro-fabriced alkali vapor cells and applications in various fields as the heart of ultraprecise sensors, like chip scale atomic clocks, magnetometers or gyroscopes. Miniaturization asks for either new fabrication techniques or new physical concepts or bo ...

Polarity Assignment in ZnTe, GaAs, ZnO, and GaN-AlN Nanowires from Direct Dumbbell Analysis

Anna Fontcuberta i Morral, Martin Heiss, Bo Peng

Aberration corrected scanning transmission electron microscopy (STEM) with high angle annular dark field (HAADF) imaging and the newly developed annular bright field (ABF) imaging are used to define a new guideline for the polarity determination of semicon ...

Existence of Eulerian Solutions to the Semigeostrophic Equations in Physical Space: The 2-Dimensional Periodic Case

Maria Colombo

In this article we use new regularity and stability estimates for Alexandrov solutions to Monge-Ampere equations, recently established by De Philippis and Figalli [14], to provide global in time existence of distributional solutions to the semigeostrophic ...

The effects of mutual location-awareness on group coordination

Pierre Dillenbourg, Nicolas Nova

The importance of space and place in collaborative practices has been strengthened with the ubiquitous computing paradigm, which aims at the integration of computation in physical objects and places. New location-based applications allow users to know wher ...

Sentiment analysis of informal textual communication in cyberspace

Daniel Thalmann, Stéphane Gobron

The ability to correctly identify the existence and polarity of emotion in informal, textual communication is a very important part of a realistic and immersive 3D environment where people communicate with one another through avatars or with an automated s ...

An Automated, yet Interactive and Portable DB designer

Anastasia Ailamaki, Ioannis Alagiannis, Debabrata Dash

Tuning tools attempt to configure a database to achieve optimal performance for a given workload. Selecting an optimal set of physical structures is computationally hard since it involves searching a vast space of possible configurations. Commercial DBMSs ...

How the mind constitutes itself through perceptual learning

Michael Herzog

Most theories of perception assume a rigid relationship between objects of the physical world and the corresponding mental representations. We show by a priori reasoning that this assumption is not fulfilled. We claim instead that all object-representation ...

A posteriori error analysis of the heterogeneous multiscale method for homogenization problems

Assyr Abdulle, Achim Nonnenmacher

In this Note we derive a posteriori error estimates for a multiscale method, the so-called heterogeneous multiscale method, applied to elliptic homogenization problems. The multiscale method is based on a macro-to-micro formulation. The macroscopic method ...
