Improved Similarity Measures for Small Sets of Spike Trains

Wulfram Gerstner, Richard Naud, Joao Emanuel Felipe Gerhard, Skander Mensi

Multiple types of measures have been developed to measure the similarity between two spike trains. These were extensively used to classify neuron responses according to stimuli and to validate mathematical models that predict the spike times. Here we analy ...

Direct Observation of Capacitor Switching Using Planar Electrodes

Alexander Tagantsev

Ferroelectric polarization switching in epitaxial (110) BiFeO3 films is studied using piezoresponse force microscopy of a model in-plane capacitor structure. The electrode orientation is chosen such that only two active domain variants exist. Studies of th ...

The influence of foreign vs. North American emissions on surface ozone in the US

As part of the Hemispheric Transport of Air Pollution (HTAP; < a href='http://www.htap.org' target='_blank'> http:// www.htap.org ) project, we analyze results from 15 global and 1 hemispheric chemical transport models and compare these to Clean Air S ...

Spatial aspects of bodily self-consciousness

Olaf Blanke, Bigna Lenggenhager, Michaël Mouthon

Visual, somatosensory, and perspectival cues normally provide congruent information about where the self is experienced. Separating those cues by virtual reality techniques, recent studies found that self-location was systematically biased to where a visua ...

Sequential Anisotropic Multichannel Wiener Filtering with Rician Bias Correction Applied to 3D Regularization of DWI Data

Jean-Philippe Thiran, Leila Cammoun

It has been shown that the tensor calculation is very sensitive to the presence of noise in the acquired images, yielding to very low-quality Diffusion Tensor Images (DTI) data. Recent investigations have shown that the noise present in the Diffusion Weigh ...

Thermally induced voltage shift in capacitance-voltage characteristics and its relation to oxide/semiconductor interface states in Ni/Al2O3/InAlN/GaN heterostructures

Nicolas Grandjean, Jean-François Carlin

The Ni/Al2O3/InAlN/AlN/GaN metal-oxide-semiconductor heterostructure (MOS-H) is investigated using capacitance-voltage and capacitance-time characteristics in the temperature range of 25-300 degrees C. An anomalous positive voltage shift of the capacitance ...

Pico-Watt Source-Coupled Logic Circuits

Seyed Armin Tajalli, Yusuf Leblebici

This article explores the main tradeoffs in design of subthreshold source-couple logic (STSCL) circuits. It is shown analytically that the bias current of each STSCL gate can be reduced to few pico-amperes with a reliable logic operation. Measurements on d ...

Pseudoferroelectricity: A possible scenario for doped ZnO

Alexander Tagantsev

A phenomenological Landau-theory model, where a crystal on cooling from a state with polar symmetry exhibits a maximum of dielectric permittivity and polarization-field hysteresis loops, is offered. The model is equivalent to that of a true ferroelectric i ...

Variations in leaf area index in northern and eastern North America over the past 21,000 years: a data-model comparison

Jed Oliver Kaplan

Over the past 10 years, there has been a growing debate about the relative importance of late-Quaternary variations in climate and CO2 as drivers of changes in vegetation structure. In this study, we compare new datasets of pollen-reconstructed leaf area i ...

Policymakers and the R&D-patent relationship

Gaétan Jean A de Rassenfosse

Patent-based indicators at the country level are frequently used to assess countries' innovation performances or efforts. Yet they are often said to reflect the propensity to patent rather than actual research productivity. The authors of this article argu ...
