Most models of speech planning and production incorporate a selection mechanism, whereby units are activated in parallel and chosen for execution sequentially. The lowest level units which can be selected are assumed to be segments, i.e. consonants and vowels. The features or articulatory gestures affiliated with segments are presumed to be automatically selected as a consequence of segmental s...

Insect and mammalian olfactory systems are strikingly similar. Therefore, Drosophila can be used as a simple model for olfaction and olfactory learning. The brain of adult Drosophila, however, is still complex. We therefore chose to work on the larva with its yet simpler but adult-like olfactory system and provide evidence for olfactory learning in individually assayed Drosophila larvae. We dev...

We are using microactuators based on a conducting polymer, polypyrrole, and demonstrate here a scheme to make true three-dimensional movements. We present a complementary microfabrication method, which was developed in order to create individually addressable and controllable PPy/Au actuators. Using these individually controlled microactuators we are able to obtain movements both out of and in ...

This paper presents a technique for programmable switchedcapacitor (SC) filters based on periodical nonuniform individual sampling (PNIS) of each SC structure in the filter. It is shown how very wide range of programmability in all circuit parameters can be obtained, whereas the dynamic range degradation is kept minimum. Experimental results obtained from a 1.2 p m CMOS second-order SC filter a...

OBJECTIVES To identify the characteristics of smoking addiction in a group of pregnant women, to evaluate the efficacy of medical counseling tailored to the patient's stage in the cessation process and to examine factors that might affect the ability of a woman to quit smoking during pregnancy. PATIENTS AND METHODS One hundred sixteen women (mean age 29.71 5.44 years; range 15-41) were referr...

Abstract We present a statistical study of the largest bibliographic compilation stellar and orbital parameters W UMa stars derived by light-curve synthesis with Roche models. The includes nearly 700 individually investigated objects from over 450 distinct publications. Almost 70% this sample is comprised observed in past decade that have not been considered previous studies. estimate ages cata...
