A microfluidic flow-cell for the study of the ultrafast dynamics of biological systems

Majed Chergui, Adrien Alexis Paul Chauvet

The study of biochemical dynamics by ultrafast spectroscopic methods is often restricted by the limited amount of liquid sample available, while the high repetition rate of light sources can induce photodamage. In order to overcome these limitations, we de ...

Live-cell multiplane three-dimensional super-resolution optical fluctuation imaging

Theo Lasser, Marcel Leutenegger, Noelia Laura Bocchio, Aurélien Godinat, Patrick Alain Sandoz, Azat Sharipov, Stefan Geissbuehler

Super-resolution optical fluctuation imaging (SOFI) provides an elegant way of overcoming the diffraction limit in all three spatial dimensions by computing higher-order cumulants of image sequences of blinking fluorophores acquired with a classical widefi ...

Potential of the Large Observatory for X-ray Timing telescope for the search for dark matter

Alexey Boyarsky, Oleg Ruchayskiy

Large observatory for x-ray timing (LOFT) is a concept of a next-generation x-ray telescope considered in the context of the "Cosmic Vision" program of the European Space Agency. The Large Area Detector on board of LOFT will be a collimator-type telescope ...

Using the CMB angular power spectrum to study Dark Matter-photon interactions

Julien Lesgourgues

In this paper, we explore the impact of Dark Matter-photon interactions on the CMB angular power spectrum. Using the one-year data release of the Planck satellite, we derive an upper bound on the Dark Matter-photon elastic scattering cross section of sigma ...

Design and operation of FACT - the first G-APD Cherenkov telescope

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz, Camille Haller

The First G-APD Cherenkov Telescope (FACT) is designed to detect cosmic gamma-rays with energies from several hundred GeV up to about 10 TeV using the Imaging Atmospheric Cherenkov Technique. In contrast to former or existing telescopes, the camera of the ...

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIV. Time delay of the doubly lensed quasar SDSS J1001+5027

Frédéric Courbin, Georges Meylan, Malte Tewes

This paper presents optical R-band light curves and the time delay of the doubly imaged gravitationally lensed quasar SDSS J1001+5027 at a redshift of 1.838. We have observed this target for more than six years, between March 2005 and July 2011, using the ...

Robotic Thumb Grasp-Based Range of Motion Optimisation

With the thumb serving an important role in the function of the human hand, improving robotic prosthetic thumb functionality will have a direct impact on the prosthesis itself. So far, no significant work exists that examines the ranges of motion a prosthe ...

Three-dimensional Super-resolution Optical Fluctuation Imaging

Theo Lasser, Marcel Leutenegger, Stefan Geissbühler, Noelia Laura Bocchio, Corinne Berclaz

Super-resolution optical fluctuation imaging (SOFI) achieves three-dimensional super-resolution by computing higher-order spatio-temporal cross-cumulants of stochastically blink-ing fluorophores. In contrast to localization microscopy, SOFI is compatible w ...

Time-resolved optical response of all-oxide YBa2Cu3O7/La0.7Sr0.3MnO3 proximitized bilayers

Yi Wang

We present femtosecond pump-probe spectroscopy studies of time-resolved optical reflectivity of all-oxide YBa2Cu3O7/La0.7Sr0.3MnO3 (YBCO/LSMO) superconductor/ferromagnet (S/F) bilayers consisting of a 100-nm-thick YBCO base layer and either 10 or 35 nm LSM ...

Optically-transparent actuators and micro-mechanical systems fabricated using femtosecond lasers

Yves Bellouard, Tao Yang

Non-linear laser-matter interaction offers the possibility to structure transparent material in three dimensions. Here, we demonstrate that such process can be implemented for fabricating novel type of microsystems, including actuators transparent to visib ...
