Wavelet domain Bayesian denoising of string signal in the cosmic microwave background

An algorithm is proposed for denoising the signal induced by cosmic strings in the cosmic microwave background (CMB). A Bayesian approach is taken, based on modeling the string signal in the wavelet domain with generalized Gaussian distributions. Good perf ...

The metazoan ATAC and SAGA coactivator HAT complexes regulate different sets of inducible target genes

Histone acetyl transferases (HATs) play a crucial role in eukaryotes by regulating chromatin architecture and locus-specific transcription. The GCN5 HAT was identified as a subunit of the SAGA (Spt-Ada-Gcn5-Acetyltransferase) multiprotein complex. Vertebra ...

Using Bibliographic Knowledge for Ranking in Scientific Publication Databases

Martin Rajman, Martin Veselý

Document ranking for scientific publications involves a variety of specialized resources (e.g. author or citation indexes) that are usually difficult to use within standard general purpose search engines that usually operate on large-scale heterogeneous do ...

Firing patterns in the adaptive exponential integrate-and-fire model

Wulfram Gerstner, Richard Naud, Claudia Clopath, Nicolas Marcille

For simulations of large spiking neuron networks, an accurate, simple and versatile single-neuron modeling framework is required. Here we explore the versatility of a simple two-equation model: the adaptive exponential integrate-and-fire neuron. We show th ...

Demonstration of cortical recording using novel flexible polymer neural probes

Philippe Renaud, Arnaud Bertsch, André Mercanzini, Karen Cheung, Marc Jasper Boers

We present the fabrication, characterization, use in cortical recording and histological results of a flexible implantable neural probe. The microfabricated device is implemented in polyimide and platinum providing mechanical flexibility, high quality elec ...

Grouping explains contextual modulation in low level vision

Michael Herzog, Bilge Sayim

Performance on a target can be modified by contextual elements. For example, when a Vernier is flanked by two lines, offset discrimination deteriorates compared to an unflanked presentation. This contextual modulation is usually explained by local spatial ...

Erosion and deposition in the JET MkII-SRP divertor

Richard Pitts

Carbon-13 labelled methane was injected into the outer divertor during a series of H-mode discharges on the last day of operations with the JET MkII-SRP divertor. Tiles from around the vessel were removed during the subsequent shutdown and surface deposits ...

Building the capacity to experiment in schools: a case study of the Institute of Educational Sciences in the U.S. department of Education

Dominique Foray

This article is about building new research capacities to foster a fundamental shift in research methods. It examines in detail the new R&D policy of the US Department of Education, which is designed to dramatically increase the number of experiments condu ...

Relaxivity of Gd-based contrast agents on X nuclei with long intrinsic relaxation times in aqueous solutions

Rolf Gruetter, Ruud van Heeswijk, Sabrina Laus

The relaxivity of commercially available gadolinium (Gd)-based contrast agents was studied for X-nuclei resonances with long intrinsic relaxation times ranging from 6 s to several hundred seconds. Omniscan in pure 13C formic acid had a relaxivity of 2.9 mM ...

Parallel and Distributed Neural Models of the Ideomotor Principle: An Investigation of Imitative Cortical Pathways

Aude Billard, Eric Sauser

Humans’ capacity to imitate has been extensively investigated through a wide-range of behavioral and developmental studies. Yet, despite the huge amount of phenomenological evidence gathered, we are still unable to relate this behavioral data to any specif ...
