The invention relates to a Stick-Slip piezoelectric actuator comprising a piezoelectric element with active zones and passive zones, said active zones being transversally deformable by applying different voltages, said passive zones not being actively defo ...
In many miniature systems for positioning and especially in microrobotics the assembly of the components becomes difficult. At sizes of systems of a few cm2 not only the assembly becomes more difficult, downscaling also means that single parts become more ...
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 ...
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 ...
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 ...
Energy consumption is a major issue for inertial drives with piezoelectric actuators that are integrated in autonomous devices. This paper discusses some theoretical aspects and some experimental results about the energy consumption of inertial drives with ...
The elemental compn. of microorganisms varies widely with respect to the N, S, P, and ash content as well as many trace elements depending on microorganism and growth conditions. As a consequence, the mass of 1 C-mol of biomass can differ considerably from ...
A Hall mobility as high as 153,800 cm2 V-1 s-1 at 77 K with N(d) - N(a) = 1.5 x 10(14) cm-3 has been obtained by adjusting the growth temperature and the phosphine cracking temperature. The 4 K photoluminescence spectra show finely resolved excitonic trans ...
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 ...
