Is there a geometric module for spatial orientation? Insights from a rodent navigation model

Wulfram Gerstner, Ricardo Andres Chavarriaga Lozano, Thomas Strösslin, Angelo Arleo

Modern psychological theories of spatial cognition postulate the existence of a geometric module for reorientation. This concept is derived from experimental data showing that in rectangular arenas with distinct landmarks in the corners, disoriented rats o ...

Weak signals as a flexible framing space for enhanced management and decision-making

Pierre Rossel

This paper revisits theories of weak signal analysis using the concepts of 'framing' and 'meta-framing' to provide an enriched methodological environment for management and decision-making in turbulent contexts. This attempt takes place within the effort t ...

APOBEC3G-depleted resting CD4+ T cells remain refractory to HIV1 infection

Didier Trono, Francesca Santoni de Sio

BACKGROUND: CD4+ T lymphocytes are the primary targets of HIV1 but cannot be infected when fully quiescent, due to a post-entry block preventing the completion of reverse transcription. Chiu et al. recently proposed that this restriction reflects the actio ...

Perceived speed differences explain apparent compression in slit viewing

Michael Herzog

When a figure moves behind a stationary narrow slit, observers often report seeing the figure as an integrated whole, a phenomenon known as slit viewing or anorthoscopic perception. Interestingly, in slit viewing, the figure is perceived compressed along t ...

Hypothesis testing for evaluating a multimodal pattern recognition framework applied to speaker detection

Murat Kunt, Patricia Besson

Background: Speaker detection is an important component of many human-computer interaction applications, like for example, multimedia indexing, or ambient intelligent systems. This work addresses the problem of detecting the current speaker in audio-visual ...

The Complexity of Distinguishing Distributions

Serge Vaudenay, Thomas Baignères

Cryptography often meets the problem of distinguishing distributions. In this paper we review techniques from hypothesis testing to express the advantage of the best distinguisher limited to a given number of samples. We link it with the Chernoff informati ...

Successive refinement for hypothesis testing and lossless one-helper problem

Jun Chen

We investigate two closely related successive refinement (SR) coding problems: 1) In the hypothesis testing (HT) problem, bivariate hypothesis H-o : P-XY against H-1 : P-X P-Y, i.e., test against independence is considered. One remote sensor collects data ...

False Discovery Rate for Wavelet-Based Statistical Parametric Mapping

Michaël Unser, Dimitri Nestor Alice Van De Ville

Model-based statistical analysis of functional magnetic resonance imaging (fMRI) data relies on the general linear model and statistical hypothesis testing. Due to the large number of intracranial voxels, it is important to deal with the multiple compariso ...

Is migraine a lateralization defect?

Nouchine Hadjikhani

Migraine often co-occurs with patent foramen ovale (PFO), and some people have suggested surgical closure as an efficient treatment for migraine. Prospective studies, however, do not report radical effect of PFO surgery on migraine. Here, we examined the h ...

Estimating the Confidence Level of White Matter Connections Obtained with MRI Tractography

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet, Maciej Kurant

Background Since the emergence of diffusion tensor imaging, a lot of work has been done to better understand the properties of diffusion MRI tractography. However, the validation of the reconstructed fiber connections remains problematic in many respects. ...
