Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II

Shirit Cohen, Mathieu Ribordy, Levent Demirörs, Xiaoxia Bai

The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be u ...

La Suisse dans une économie globalisée de la connaissance

Dominique Foray, Stéphane Lhuillery

Rapport préparé pour l'étude intitulée "Où en est la Suisse dans l'économie du savoir? Pôle d'excellence et pôle de croissance", commandée par l'Office Fédéral de la Formation Professionnelle et de la Technologie (OFFT) et le Secrétariat d'Etat à l'Educati ...

PLP$^2$: Autoregressive modeling of auditory-like 2-D spectro-temporal patterns

Hynek Hermansky

The temporal trajectories of the spectral energy in auditory critical bands over 250~ms segments are approximated by an all-pole model, the time-domain dual of conventional linear prediction. This quarter-second auditory spectro-temporal pattern is further ...

Vieillissement et fiabilité des parcs de poteaux bois des réseaux de lignes aériennes

Yann Benoit

The reliability of new overhead electric and telecommunication lines depends principally on the quality of their support structures. These structures are generally made of wood, metal or concrete. The complexity of a natural substance such as wood requires ...

A gene network establishing polarity in the early mouse embryo

Daniel Constam

In mammalian embryos, molecular cross-talk with extraembryonic tissues is essential to elaborate the primary body axes. Here, we review a series of reciprocal interactions that occur shortly after implantation in the uterus, and discuss how they are integr ...

Investigation of the consistency of magnetic and soft X-ray plasma position measurements on TCV by means of a rapid tomographic inversion algorithm

Basil Duval, Stefano Coda, Timothy Goodman, Xavier Llobet, Henri Weisen, Jonathan Bryan Lister

A rapid algorithm for tomographic inversion is presented that allows post-discharge reconstruction of the soft x-ray (SXR) emissivity evolution in the Tokamak a configuration variable (TCV). Simultaneously, it determines the centre of gravity of the emissi ...

Efficient, narrow linewidth excitonic emission at room temperature from GaAs/AlGaAs V-groove quantum wire light-emitting diodes

Elyahou Kapon, Alok Rudra, Marc-André Dupertuis

We report on efficient, narrow linewidth exciton recombination in GaAs/AlGaAs V-groove quantum wire light-emitting diodes at room temperature. The high efficiency is due to a selective carrier injection mechanism resulting in an estimated internal quantum ...

Effect of tilted magnetic fields on bistable nanomagnets in hybrid semiconductor/ferromagnet devices

Dirk Grundler

Using the anisotropic Hall effect in a sub-micron lithographically well-defined two-dimensional electron system we measure the stray field of individual ferromagnetic nanoparticles in tilted magnetic fields. Our model calculations and experimental data sho ...

Modified Lead Calcium Titanate Ceramics with a Relatively Large Dielectric-Constant for Hydrophone Applications

Dragan Damjanovic

Modified lead titanate of the base composition (Pb,Ca)Ti-(Co,W)O3 + 0.01 mol % MnO was doped with 2 to 6 mol % strontium and barium to increase the dielectric constant, K, while preserving a high piezoelectric anisotropy (d33/d31). K was increased above 50 ...
