Interaction of spatial and temporal integration in global form processing

Jane Aspell

The mechanisms by which global structure is extracted from local orientation information are not well understood. Sensitivity to global structure can be investigated using coherence thresholds for detection of global forms of varying complexity, such as pa ...

Mechanical behaviour of Ultra High Performance Fibre Reinforced Concretes (UHPFRC) at early age, and under restraint

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

At early age, ultra high performance fibre reinforced concretes (UHPFRC)undergo significant volumes changes (thermal deformation and autogenous shrinkage)related to their composition. These deformations can be restrained by different elements respective to ...

High resolution miniature rotary microactuator

Jean-Marc Breguet, Walter Driesen

For the development of high precision mobile microrobots with a size of about one cm3, capable of micromanipulation tasks, small and precise actuators have to be developed in order to provide the microrobot and its manipulation tools with the required degr ...

Separable Term Structures and the Maximal Degree Problem

Damir Filipovic

This paper discusses separable term structure diffusion models in an arbitrage-free environment. Using general consistency results we exploit the interplay between the diffusion coefficients and the functions determining the forward curve. We introduce the ...

Stereotypy in neocortical microcircuits

Henry Markram, Gilad Silberberg

A central debate regarding neocortical function concerns the degree to which the underlying microcircuitry is stereotypically organized. Stereotypy reflects invariance in structure and function, as a result of common genetic templates and environmental con ...

Directional effects in photonic bandgap cavities

Romuald Houdré, Ursula Oesterle, Henri Benisty

We present here measurements on hexagonal cavities that have areas between 2.0 and 8.6 mu m/sup 2/. The 2D triangular lattice PBG mirrors are etched into a GaAs/AlGaAs waveguide heterostructure with 3 layers of InAs quantum dots at the centre of a 240 nm t ...

The evolution of 'bricolage'

Denis Duboule

The past ten years of developmental genetics have revealed that most of our genes are shared by other species throughout the animal kingdom. Consequently, animal diversity might largely rely on the differential use of the same components, either at the ind ...

Inositol triphosphate produces different patterns of cytoplasmic Ca2+ spiking depending on its concentration

Carl Petersen

In single mouse pancreatic acinar cells the effects of intracellular infusion of inositol 1,4,5-trisphosphate (InsP3) or the non-metabolizable InsP3 analogue inositol 1,4,5-triphosphorothioate (InsPS3) have been investigated using a wide range of concentra ...

A calorimetric study of microbial growth energetics

Urs von Stockar, Ian William Marison

Isothermal reaction calorimetry was employed on the bench scale to measure the enthalpy efficiency and O2 efficiency of growth of several microbial strains cultured on a range of substrates with varying degrees of redn. The obsd. values of these energetic ...
