The potential of the vertebrate limb as a model system to study developmental mechanisms is particularly well illustrated by the analysis of the Hox gene network. These genes are involved in the establishment of patterns and encode positional information. ...
A broad range of high-volume consumer applications require low-power battery-operated wireless microsystems and sensors. These systems should conciliate a sufficient battery lifetime with reduced dimensions, low cost, and versatility. Their design highligh ...
In this paper we describe the evolution of a discrete-time recurrent neural network to control a real mobile robot. In all our experiments the evolutionary procedure is carried out entirely on the physical robot without human intervention. We show that the ...
Artificial respirators use an electric source of energy to supply the various active components which control the airflow. A portable or autonomous respirator (emergency, war, ambulance, etc), needs a battery or an energy container to be supplied with grea ...
The research and development of a durable, elec. rechargeable Zn/O2 battery in the PSI-BEW project at the Paul Scherrer Institute is described in a review with many refs. The first phase included the development of La0.6Ca0.4CoO3-activated bifunctional O2 ...
In this article the development and realization of a 8 kW battery charger with Power Factor Correction (PFC) is described. The converter consists of two parts: The first part is an AC/DC converter based on a “VIENNA” topology with a controlled output volta ...
Recent progresses in the technology of the Ni-Zn batteries have a direct influence on the improvement of the performance of hybrid electric vehicles. This paper evaluates the progresses of these batteries in particular for application on hybrid light vehic ...
A low-power transceiver for ISM applications in the 868-MHz band has been integrated in a 0.8-μm BiCMOS technology. The receiver part is based on the super-regenerative principle. The system includes two time-shared control loops, one for the selectivity a ...
The incorporation of up to 40 % lead excess into the perovskite lattice of Pb(Zr,Ti)O-3 (PZT) has been investigated. Three independent chemical composition analysis methods confirmed the correct determination of the lead excess, present as Pb2O3. High reso ...
Huntington's disease (HD) is an autosomal dominant genetic disease with devastating clinical effects on cognitive, psychological, and motor functions. These clinical symptoms primarily relate to the progressive loss of medium-spiny GABA-ergic neurons of th ...
