Abstract: An optical arrangement for direct laser interference structuring. A laser beam is directed to a reflecting mirror with inclined surface and strikes a first beam splitter, it is divided into two partial beams and one partial beam is deflected to a focusing element. The second partial laser beam is directed to a first pentamirror and after multiple reflection and/or refraction, the focusing element, or it is directed to a second beam splitter and is divided into a first partial beam and a third partial beam. The partial beams are directed to the focusing element by the first pentamirror and are directed by the focusing element to the surface to be structured interfering with each other. The reflecting mirror is moved in a translational manner, maintaining a 45° angle parallel to the optical axes of the emitted laser beam influencing the interference period ?.

Abstract: A transistor structure includes a first terminal region, a second terminal region and a channel region therebetween in a semiconductor substrate. Additionally, the transistor structure includes a control electrode associated with the channel region, the control electrode having a control electrode portion which is elastically deflectable under the action of a force and spaced apart from the channel region. The distance between the control electrode portion and the channel region is changed based on the action of force.

Abstract: A silicon-ceramic composite substrate includes a low-temperature ceramic having at least one pre-formed ceramic layer and a silicon substrate. The low-temperature ceramic forms a carrier layer and the silicon substrate surface has a contact area with nanostructures) that completely penetrate into the low-temperature ceramic.

Abstract: The invention relates to a method for treating a biological cell (1) including a cytoskeleton (3) enveloped by a cell membrane (2). The method includes the following steps: the biological cell (1) and a tool (10) are mutually oriented such that the tool (10) comes into contact with the biological cell (1); the tool (10) and the biological cell (1) are displaced in relation to each other; and a gap is formed in the molecular composite of the cell membrane (2) of the biological cell (1). During the displacement of the tool (10), the cytoskeleton (3) of the biological cell (1) has a state of equilibrium. The invention also relates to a cell manipulator for carrying out the inventive method.

Abstract: Parameters being a measure for a characteristic of a channel or of a pair of channels, wherein the parameter is a measure for a characteristic of the channel or of the pair of channels with respect to another channel of a multi-channel signal can be quantized more efficiently using a quantization rule that is generated based on a relation of an energy measure of the channel or the pair of channels and an energy measure of the multi-channel signal. With generation of the quantization rule taking into account a psycho acoustic approach, the size of an encoded representation of the multi-channel signal can be decreased by coarser quantization without significantly disturbing the perceptual quality of the multi-channel signal when reconstructed from the encoded representation.

The cell connector thereby includes at least one electrically conductive layer which is configured as a transit region and via contact regions which constitute merely a fraction with respect to the total surface area of the transit region is contacted with the current source.

Abstract: A device for pretreating a signal to be transmitted over a transmission path, wherein the transmission path comprises a band-pass filter whose pass-band width is smaller than a predetermined bandwidth and a non-linear amplifier, includes a linearization means for performing a linearization of the signal to be transmitted before the transmission of the same, such that a non-linearity caused by the non-linear amplifier is counteracted. Further, the device includes a signal-shaping means downstream to the linearization means comprising a frequency response such that the overall frequency response of the signal-shaping means and the band-pass filter corresponds to the frequency response of a filter whose pass-band width is at least equal to the predetermined bandwidth.
