Generalized tensor idempotents and the telescope conjecture

We transpose Rickard's construction of idempotent representations to the general context of tensor triangulated categories. We connect our construction to the telescope conjecture and prove that the latter is of local nature. As an illustration, we extend ...

Statistics for the Clinician: Diagnostic Questionnaires

The goal of this column is to help working clinicians understand the statistical calculations involved in interpreting the results of diagnostic questionnaires. Using the Patient Health Questionnaire-9 as an example, the author explains how to determine th ...

How do electron localization functions describe p-electron delocalization?

Scalar fields provide an intuitive picture of chemical bonding. In particular, the electron localization function (ELF) has proven to be highly valuable in interpreting a broad range of bonding patterns. The discrimination between enhanced or reduced elect ...

Le coût attentionnel associé aux fonctions exécutives impliquées dans le contrôle postural

Estelle Palluel, Jean-Baptiste Mignardot

The present paper tried to provide a review of the different works investigating the attentional cost of postural control. Within the context of a dual-task, the attentional demand associated with postural control depends on various factors such as (1) the ...

The Optima project: inferring transport mode preferences from attitude

Michel Bierlaire, Aurélie Glerum, Bilge Atasoy, Antonin Danalet, Anne Curchod

Objectives, data collection, model estimation, elasticities, value of time and validation in the context of the Optima project, a collaborative work between EPFL’s Transportation Center (TraCe) and CarPostal, the public transport branch of the Swiss Postal ...

Structuring and integrating human knowledge in demand forecasting: a judgemental adjustment approach

Naoufel Cheikhrouhou

Demand forecasting consists of using data of the past demand to obtain an approximation of the future demand. Mathematical approaches can lead to reliable forecasts in deterministic context through extrapolating regular patterns in time-series. However, un ...

Spread spectrum for interferometric and magnetic resonance imaging

Jean-Philippe Thiran, Rolf Gruetter, Pierre Vandergheynst, Dimitri Nestor Alice Van De Ville, Yves Wiaux, Gilles Puy

We consider images probed through incomplete and noisy Fourier coverages, both in the context of radio interferometry (RI) and of magnetic resonance imaging (MRI). We show that the quality of signal reconstruction can be signiﬁcantly enhanced by the introd ...

On the reproducibility and anatomical correspondence of DSI tractography

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Alessandro Daducci, Cristina Granziera, Leila Cammoun, Xavier Gigandet

Diffusion spectrum imaging (DSI) is increasingly explored in clinical research. The quantitative value of the DSI technique, however, has still to be established. In this context, a better understanding of the reproducibility and the anatomical corresponde ...

A Variational Framework for Structure from Motion in Omnidirectional Image Sequences

Pascal Frossard, Pierre Vandergheynst, Luigi Bagnato

We address the problem of depth and ego-motion estimation from omnidirectional images. We propose a correspondence-free structure from motion problem for images mapped on the 2-sphere. A novel graph-based variational framework is proposed for depth estimat ...

Improved estimation of travel demand from traffic counts by a new linearization of the network loading map

Michel Bierlaire, Gunnar Flötteröd

Abstract In the context of dynamic traffic assignment (DTA), the network loading map represents a traffic flow model. Assuming that an iterative DTA microsimulator is given, this article discusses several techniques for the linearization of the network loa ...
