High order discontinuous Galerkin methods on simplicial elements for the elastodynamics equation

In this work we apply the discontinuous Galekin (dG) spectral element method on meshes made of simplicial elements for the approximation of the elastodynamics equation. Our approach combines the high accuracy of spectral methods, the geometrical flexibilit ...

Use of fourier transform infrared spectroscopy analysis of extracellular vesicles isolated from body fluids for diagnosing, prognosing and monitoring pathophysiological states and method therfor

Horst Vogel, Luigino Grasso, Romain Wyss

The method analyzes biological fluids collected from patients, and uses attenuated total reflecting (ATR) sensors and spectral analysis by Fourier transform infrared spectroscopy (FTIR) to form a spectral fingerprint of extracellular vesicles (EVs) isolate ...

A Guided Tour of Selected Image Processing and Analysis Methods for Fluorescence and Electron Microscopy

Michaël Unser

Microscopy imaging, including fluorescence microscopy and electron microscopy, has taken a prominent role in life science research and medicine due to its ability to investigate the 3D interior of live cells and organisms. A long-term research in bio-imagi ...

Demultiplexing Visible and Near-Infrared Information in Single- Sensor Multispectral Imaging

Sabine Süsstrunk, Zahra Sadeghipoor Kermani, Jean-Baptiste Thomas

In this paper, we study a single-sensor imaging system that uses a multispectral filter array to spectrally sample the scene. Our system captures information in both visible and near-infrared bands of the electromagnetic spectrum. Due to manufacturing limi ...

Hybridization and electron-phonon coupling in ferroelectric BaTiO3 probed by resonant inelastic x-ray scattering

Marco Grioni, Simon Karl Moser, Sara Fatale

We investigated the ferroelectric perovskite material BaTiO3 by resonant inelastic x-ray scattering (RIXS) at the Ti L-3 edge. We observe with decreasing temperature a transfer of spectral weight from the elastic to the charge-transfer spectral features, i ...

First-Principles Photoemission Spectroscopy of DNA and RNA Nucleobases from Koopmans-Compliant Functionals

Nicola Marzari, Giovanni Borghi, Andrea Ferretti

The need to interpret ultraviolet photoemission data strongly motivates the refinement of first-principles techniques that are able to accurately predict spectral properties. In this work, we employ Koopmans-compliant functionals, constructed to enforce pi ...

A Simple, Fast and Low-Cost Method for in situ Monitoring of Topographical Changes and Wear Rate of a Complex Tribo-System Under Mixed Lubrication

Daniel Sage, Bastian Meylan

This contribution presents a simple, fast, and low-cost method to track in situ and in real time the evolution of the surface topography. The method combines an optical method (collimated light) with image analysis. The method was validated using a complex ...

Homonuclear decoupling for spectral simplification of carbon-13 enriched molecules in solution-state NMR enhanced by dissolution DNP

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Diego Carnevale, Srinivas Chinthalapalli

Complex overlapping multiplets due to scalar couplings (n)J(C-13, C-13) in fully C-13-enriched molecules can be simplified by polychromatic irradiation of selected spins. The signal intensities of the remaining non-irradiated signals are proportional to th ...

Definition and assessment of reference values for PMU calibration in static and transient conditions

Mario Paolone, Guglielmo Frigo, Marco Pignati, Daniele Colangelo

The calibration of Phasor Measurement Units (PMUs) consists of comparing Coordinated Universal Time (UTC) time-stamped phasors (synchrophasors) estimated by the PMU under test, against reference synchrophasors generated through a PMU calibrator. The IEEE S ...

Effect of Hypoxia and Hyperoxia on Baroreflex Sensitivity

Jean-Marc Vesin, Sasan Yazdani

This paper is part of a series titled “AltitudeOmics” that together represent a group of studies that explore the basic mechanisms controlling human acclimatization to hypoxia. This study aims at analyzing the baroreflex sensitivity (BRS) at sea level, in ...
