Multitrack electrospray chips (MTEC) were fabricated by UV-photoablation of polyethylene terephthalate (PET) substrates. They are composed of an array of up to six microchannels that are successively used as electrospray ionization (ESI) emitters for mass ...
Neurons generate spikes reliably with millisecond precision if driven by a fluctuating current—is it then possible to predict the spike timing knowing the input? We determined parameters of an adapting threshold model using data recorded in vitro from 24 l ...
Gamma-secretase is an intramembrane-cleaving aspartyl protease required for the normal development of metazoans because it processes Notch within cellular membranes to release its signaling domain. More than two dozen additional substrates of diverse funct ...
This thesis is a contribution to the field of cellular communication in arteries during vasomotion, i.e. rhythmic and spontaneous diameter oscillations of arteries. Investigating how individual smooth muscle cells (SMCs) and endothelial cells (ECs) calcium ...
We have built a model organic field-effect transistor that is basically composed of a single layer of pentacene crystal in interaction with an oxide surface. Drain and source contacts are ohmic so that the pentacene layer can carry a current density as hig ...

The thesis presented here describes studies of ligand binding, function, and arrangement of ligand-gated ion channels in cell membranes. Fluorescence microscopy and the patch clamp technique are used to investigate the nicotinic acetylcholine receptor and ...
In this work we present a multichannel EEG decomposition model based on an adaptive topographic time-frequency approximation technique. It is an extension of the Matching Pur- suit algorithm and called Dependency Multichannel Matching Pursuit (DMMP). It ta ...
The subthreshold membrane voltage of a neuron in active cortical tissue is a fluctuating quantity with a distribution that reflects the firing statistics of the presynaptic population. It was recently found that conductance-based synaptic drive can lead to ...
In this paper, we present an interactive motion deformation method to modify animations so that they satisfy a set of prioritized constraints. Our approach successfully handles the problem of retargeting and adjusting a motion, as well as adding significan ...
The subject of this thesis is the study of the structure and function of the human muscle nicotinic acetylcholine receptor (nAChR), which is a typical member of the large class of ligand-gated ion channels. Appropriate techniques, like site-directed mutage ...
