Adaptive Strategy for the Statistical Analysis of Connectomes

Jean-Philippe Thiran, Stephan Morgenthaler, Reto Meuli, Patric Hagmann, Djalel Eddine Meskaldji, Leila Cammoun

We study an adaptive statistical approach to analyze brain networks represented by brain connection matrices of interregional connectivity (connectomes). Our approach is at a middle level between a global analysis and single connections analysis by conside ...

An Information Theoretic Combination of MFCC and TDOA Features for Speaker Diarization

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

This correspondence describes a novel system for speaker diarization of meetings recordings based on the combination of acoustic features (MFCC) and time delay of arrivals (TDOAS). The first part of the paper analyzes differences between MFCC and TDOA feat ...

KL Realignment for Speaker Diarization with Multiple Feature Streams

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

This paper aims at investigating the use of Kullback-Leibler (KL) divergence based realignment with application to speaker diarization. The use of KL divergence based realignment operates directly on the speaker posterior distribution estimates and is comp ...

Daily streamflow analysis based on a two-scaled gamma pulse model

Andrea Rinaldo, Gianluca Botter

In this paper, we develop a simple analysis method to infer some properties of the watershed processes from daily streamflow data. The method is built on a simple streamflow model with a link to rainfall stochasticity, which characterizes the streamflow as ...

Reionization by UV or X-ray sources

Yves Revaz

We present simulations of the 21-cm signal during the epoch of reionization. We focus on properly modeling the absorption regime in the presence of inhomogeneous Wouthuysen-Field effect and X-ray heating. We ran radiative transfer simulations for three ban ...

Localization through Surface Folding in Solid Foams under Compression

Pedro Miguel Nunes Pereira de Almeida Reis

We report a combined experimental and theoretical study of the compression of a solid foam coated with a thin elastic film. Past a critical compression threshold, a pattern of localized folds emerges with a characteristic size that is imposed by an instabi ...

Geostatistical simulation of 2D fields of raindrop size distributions at the meso-gamma scale

Alexis Berne, Marc Schleiss

The large variability of the drop size distribution (DSD) in space and time must be taken into account to improve remote sensing of precipitation. The ability to simulate a large number of 2D fields of DSD sharing the same statistical properties provides a ...

Scaling of double and single stranded DNA

Giovanni Dietler

Long double stranded DNA (DsDNA) and single stranded DNA (ssDNA) molecules were studied by direct imaging with the Atomic Force Microscope (AFM) in order to determine their scaling properties, exponents, distributions and persistence length in the frame wo ...
