Hint for a TeV neutrino emission from the Galactic Ridge with ANTARES

Andrii Neronov, Javier García Hernández, Randoald Müller

Interactions of cosmic ray protons, atomic nuclei, and electrons in the interstellar medium in the inner part of the Milky Way produce γ-ray flux from the Galactic Ridge. If the γ-ray emission is dominated by proton and nuclei interactions, a neutrino flux ...

Measurement of the inclusive and differential t(t)over-bar gamma cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at root s=13 TeV

Matthias Finger, Varun Sharma, Olivier Martin, Ian Smith, Jean-François Carlin, Arvind Shah, Rakesh Chawla, Thomas Mountford, Chao Wang, João Miguel das Neves Duarte

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 ...

Design and modeling of self-aligned nano-imprinted sub-micrometer pentacene-based organic thin-film transistors

Christian Enz, Jean-Michel Sallese, Rolando Ferrini, Randoald Müller, Nenad Marjanovic, Frédéric Zanella

Sub-micrometer channel length (0.5 mu m) organic thin-film transistors (OTFTs) are demonstrated using a process flow combining nano-imprint lithography (NIL) and self-alignment (SA). A dedicated test structure was designed and samples were fabricated on 4- ...

Uniaxial deformation of microcellular metals: model systems and simplified analysis

Andreas Mortensen, Frédéric Diologent, Yves Conde, Sébastien Philippe Soubielle, Randoald Müller, Etienne Combaz, Jean-François Despois

Microcellular aluminium can be produced by a process known as replication; this involves the infiltration of a packed bed of NaCl particles which are subsequently leached after metal solidification. The resulting material features a uniform distribution of ...

Focusing and continuous separation of cells in a microfluidic device using lateral dielectrophoresis

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre, Randoald Müller

We have fabricated a microfluidic device based on a novel geometrical arrangement of lateral metal electrodes and a patterned insulator. Our device combines the concept of insulator-based “electrodeless” dielectrophoresis with multiple frequencies to achie ...

Tensile flow stress of ceramic particle-reinforced metal in the presence of particle cracking

Andreas Mortensen, Ludger Weber, Andreas Rossoll, Randoald Müller

A simplified model is proposed to quantity the effect of damage in the form of particle cracking on the elastic and plastic behaviour of particle-reinforced metal matrix composites under uniaxial tensile loading: cracked particles are simply replaced, in a ...

Tensile behaviour of discontinuous two-phase materials : influence of matrix flow stress and internal damage

Randoald Müller

Particle reinforced metal matrix composites are manufactured by high-pressure infiltration. These composites contain roughly 50% by volume of discrete alumina inclusions dispersed homogeneously in a continuous aluminium-based matrix. Three matrices, namely ...

Local delivery of bisphosphonate from coated orthopedic implants increases implants mechanical stability in osteoporotic rats

Dominique Pioletti, Bastian Peter, Randoald Müller

Patients with osteoporosis and joint disabilities represent a constant growing and challenging population to be treated in the musculoskeletal clinical field. Especially in the case of total hip arthroplasty, new solutions should be developed to compensate ...
