Future water temperature of rivers in Switzerland under climate change investigated with physics-based models

Michael Lehning, Wolf Hendrik Huwald, Adrien Michel, Bettina Schaefli, Nander Wever

River ecosystems are highly sensitive to cli-mate change and projected future increase in air tempera-ture is expected to increase the stress for these ecosystems. Rivers are also an important socio-economic factor impact- ing, amongst others, agriculture, ...

Probing sub-eV Dark Matter decays with PTOLEMY

Alexey Boyarsky, Kyrylo Bondarenko

When the Dark Matter mass is below the eV-scale, its cosmological occupation number exceeds the ones of photons from the cosmic microwave background as well as of relic neutrinos. If such Dark Matter decays to pairs of neutrinos, it implies that experiment ...

Linearized supergravity with a dynamical preferred frame

Sergey Sibiryakov

We study supersymmetric extension of the Einstein-aether gravitational model where local Lorentz invariance is broken down to the subgroup of spatial rotations by a vacuum expectation value of a timelike vector field called aether. Embedding aether into a ...

Monitoring the effects of dexamethasone treatment by MRI using in vivo iron oxide nanoparticle-labeled macrophages

Heinrich Hofmann, Lionel André Maurizi, Géraldine Sylvie Coullerez

Introduction: Rheumatoid arthritis (RA) is a chronic disease causing recurring inflammatory joint attacks. These attacks are characterized by macrophage infiltration contributing to joint destruction. Studies have shown that RA treatment efficacy is correl ...

Dynamics Modeling and Control Architecture for Efficient, Manoeuvrable and Robust Monoped Hopping over Rough Terrain

Auke Ijspeert, Salman Faraji, Soha Pouya, Rico Möckel

Leg dynamics and control have been widely studied using mass-spring systems such as the Spring Loaded Inverted Pendulum (SLIP) model [1]. The SLIP model is commonly accepted as the simplest model that resembles leg dynamics. While simplicity facilitates th ...

Analysis of Galileo E5 and E5ab code tracking

Pierre-André Farine, Cyril Botteron, Aleksandar Jovanovic, Youssef Tawk

The world of global navigation satellite systems has been enhanced with several new or improved signals in space aiming to optimize accuracy, reliability, navigation solution, and interoperability between different constellations. However, such development ...

A three dimensional probe positioner

Ivo Furno, Xin Sun

In order to sort out the physics that is important in many plasma experiments, data in three dimensions 3D are becoming necessary. Access to the usual cylindrical vacuum vessel is typically restricted to radially or axially insertable probes that can pivot ...

Multigrid block matching motion estimation for generic video coding

Frédéric Dufaux

Motion estimation and compensation techniques have shown their efficiency to reduce temporal redundancies in video coding applications. Motion estimation analyzes the movement of objects in the scene. The resulting motion information allows to improve inte ...
