Spinor stochastic resonance
Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour
We report on noise-induced spin ordering in a collective quasiparticle system: spinor stochastic resonance. Synergetic interplay of a polarization-modulated signal and a polarization noise allows us to switch coherently between the two metastable states of ...

Aleksandra Radenovic, Lorenz Jan Steinbock, Roman Bulushev, Camille Alice Raillon, Swati Krishnan
The effect of electron irradiation-induced shrinking on glass nanocapillaries with diameters ranging from 75 to 14 nm was analyzed by measuring the conductance characteristics with and without DNA translocation. We have investigated nanocapillary shrinking ...
American Chemical Society2013Unedited in vivo detection and quantification of gamma-aminobutyric acid in the occipital cortex using short-TE MRS at 3 T
Short-TE MRS has been proposed recently as a method for the in vivo detection and quantification of gamma-aminobutyric acid (GABA) in the human brain at 3 T. In this study, we investigated the accuracy and reproducibility of short-TE MRS measurements of GA ...
Wiley-Blackwell2013Optical Coherence Correlation Spectroscopy (OCCS)
Theo Lasser, Christophe Pache, Marcel Leutenegger, Arno Pino Bouwens, Stefan Geissbühler, Daniel Pawel Szlag, Akihiro Sato, Stéphane Broillet
A classical technique to monitor dynamical processes at the single-molecule level is fluorescence correlation spectroscopy (FCS). However, FCS requires fluorescent labels that are typically limited by photobleaching and saturation. We present a new method, ...
2013Time gated phase-correlation distributed Brillouin fibre sensor
Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Andrey Denisov
A random access distributed Brillouin fibre sensor is presented, based on phase modulation using a pseudo-random bit sequence (PRBS) together with time gating. The standard phase-correlation technique is known to show a noise level increasing linearly with ...
Spie-Int Soc Optical Engineering2013Spatio-Temporal Regularization Of Flow-Fields
Michaël Unser, Nikolaos Stergiopoulos, Emrah Bostan, Pouya Dehghani Tafti, Orestis Vardoulis, Davide Piccini
We introduce a novel variational framework for the regularized reconstruction of time-resolved volumetric flow fields. Our objective functional takes the physical characteristics of the underlying flow into account in both the spatial and the temporal doma ...

We present optical coherence correlation spectroscopy (OCCS), a novel method to study the motion dynamics of nanoparticles within many observation volumes simultaneously. For this purpose, OCCS combines the key features of dark-field optical coherence micr ...
2013Contrast Enhancement in Optical Coherence Microscopy
Optical Coherence Microscopy (OCM) is a three-dimensional imaging technique that provides cross-sectional views of the subsurface microstructure of biological tissue, with a high axial and lateral resolution. In OCM, a low time coherence light source is sp ...
EPFL2012A comparison of in vivo (13) C MR brain glycogen quantification at 9.4 and 14.1 T
Rolf Gruetter, Yves Pilloud, Ruud van Heeswijk
The high molecular weight and low concentration of brain glycogen render its noninvasive quantification challenging. Therefore, the precision increase of the quantification by localized (13) C MR at 9.4 to 14.1 T was investigated. Signal-to-noise ratio inc ...
2012Impact of Loss Variations on Double-Ended Distributed Temperature Sensors Based on Raman Anti-Stokes Signal Only
Marcelo Alfonso Soto Hernandez
We present a theoretical and experimental analysis of the sensing capabilities of Raman-based distributed temperature optical fiber sensor (RDTS) systems using only the anti-Stokes (AS) component in loop configuration. In particular, the effects of time- a ...
