Measurement and characterization of room impulse responses

Room acoustics refers to the audio capture of an enclosed room. It can be seen as its color and fully describes the characteristics of the room, including the shape, size or the population. The goal of the project is to set up a database of Room impulse re ...

Jahn-Teller versus quantum effects in the spin-orbital material LuVO3

Paul Gregory Freeman, Sándor Tóth, Mechthild Enderle

We report on combined neutron and resonant x-ray scattering results, identifying the nature of the spin-orbital ground state and magnetic excitations in LuVO3 as driven by the orbital parameter. In particular, we distinguish between models based on orbital ...

Decoupling of Magnetic Resonance Signals in Time and Frequency Domain

Nuclear magnetic resonance (NMR) was discovered in the first half of the 20th century. Today, neither analytical chemistry without NMR spectroscopy nor medical diagnostics without magnetic resonance imaging (MRI) could be imagined. A magnetic resonance sig ...

I4U Submission to NIST SRE 2012: a large-scale collaborative effort for noise-robust speaker verification

Sébastien Marcel, Laurent El Shafey, Ma Bin, Gang Liu

I4U is a joint entry of nine research Institutes and Universities across 4 continents to NIST SRE 2012. It started with a brief discussion during the Odyssey 2012 workshop in Singapore. An online discussion group was soon set up, providing a discussion pla ...

Improving Sensitivity in Solid State NMR

Sensitivity in Nuclear Magnetic Resonance (NMR), especially in solid-state NMR, has always been a challenging and important issue and thus a motivation for new developments. The magnetic field B0, the gyromagnetic ratios of the observed nuclei, as well as ...

The Exact Hausdorff Measure of the Zero Set of Fractional Brownian Motion

Thomas Mountford, Driss Baraka

Let {X(t), t is an element of R-N} be a fractional Brownian motion in R-d of index H. If L(0,I) is the local time of X at 0 on the interval I subset of R-N, then there exists a positive finite constant c(=c(N,d,H)) such that ...

Extending Timescales and Narrowing Linewidths in NMR

Geoffrey Bodenhausen, Aurélien Bornet, Pascal Miéville, Sami Jannin, Diego Carnevale, Paul Romeo Vasos, Simone Ulzega, Marc Anthony Caporini, Nicola Salvi, Martial Rey

Among the different fields of research in nuclear magnetic resonance (NMR) which are currently investigated in the Laboratory of Biomolecular Magnetic Resonance (LRMB), two subjects that are closely related to each other are presented in this article. On t ...

Line-narrowing in proton-detected nitrogen-14 NMR

Geoffrey Bodenhausen, Simone Cavadini, Simone Ulzega

In solids spinning at the magic angle, the indirect detection of single-quantum (SQ) and double-quantum (DQ) N-14 spectra (l = 1) via spy nuclei S = 1/2 such as protons can be achieved in the manner of heteronuclear single- or multiple-quantum correlation ...

Liberalization and Competition in Postal Markets: Decentralized Infrastructure versus Cherry Picking

Martin Maegli

New entrants in postal markets usually set up delivery networks by concentrating on urban areas and large business customers. This implies that they operate their network highly centralized - at least in early phases of entrance. ...
