Abstract
Embodiments according to a first aspect of the present invention are based on the idea, that neural network parameters may be compressed more efficiently by using a non-constant quantizer, but varying same during coding the neural network parameters, namely by selecting a set of reconstruction levels depending on quantization indices decoded from, or respectively encoded, into the data stream for previous or respectively previously encoded neural network parameters. Embodiments according to a second aspect of the present invention are based on the idea that a more efficient neural network coding may be achieved when done in stages—called reconstruction layers to distinguish them from the layered composition of the neural network in neural layers—and if the parametrizations provided in these stages are then, neural network parameter-wise combined to yield a neural network parametrization improved compared to any of the stages.

Abstract
An apparatus for generating a bandwidth extended signal from an input signal includes a patch generator and a combiner. The input signal is represented for first and second bands by first and second resolution data, respectively, the second resolution being lower than the first. The patch generator generates first and second patches from the first band of the input signal according to first and second patching algorithms, respectively. A spectral density of the second patch generated using the second patching algorithm is higher than a spectral density of a first patch generated using the first patching algorithm. The combiner combines both patches and the first band of the input signal to obtain the bandwidth extended signal. The apparatus scales the input signal according to the first and second patching algorithms or scales the first and second patches, so that the bandwidth extended signal fulfills a spectral envelope criterion.

Abstract
A higher modulation speed is achieved by designing a semiconductor optical device in such a manner that a ridge semiconductor structure which, along with a semiconductor substrate and an active layer formed between the ridge semiconductor structure and the semiconductor substrate, forms a diode of the semiconductor optical device, widens from the active layer towards a face of the ridge semiconductor structure facing away from the active layer, and if the active layer is laterally confined to be within a projection of the face onto the active layer in a direction perpendicular onto the semiconductor substrate. In particular, by this means, it is possible to structure the active layer in a self-aligned manner by using the face of the ridge semiconductor structure facing away from the active layer as a mask in dry etching, and thereby structuring, the active layer.

Abstract
Sub-picture extraction is rendered less complex by providing each slice with start position information which indicates a starting position from which onwards the picture is, along a coding path, encoded into the respective slice, relative to an onset position at which the coding path starts traversing a segment the starting position is located in. Alternatively or additionally, sub-picture extraction processes are treated like choosing one layer out of a multi-layer datastream.

Abstract
A user device, UE, for a wireless communication network, like a 3rd Generation Partnership Project, 3GPP, network, is described. The UE is to perform a sidelink, SL, communication using a channel including resources from an unlicensed spectrum. The UE is to occupy the channel within a channel occupancy time, COT, and share the COT with a further UE, wherein the COT has a first part and a second part, the first part of the COT and the second part of the COT being separated by a guard duration. The UE is to perform a transmission over the SL during the first part of the COT. The second part of the COT is used by the further UE to perform a transmission over the SL. The UE is to extend the transmission into the guard duration so as to transmit during a predefined time duration starting at the beginning of the guard duration, the predefined time duration selected such that a remaining duration of the guard duration is sufficient to allow the further UE to perform a predefined channel access procedure, CAP, before accessing the shared COT.

Abstract
A device for applying a bead of material includes a flexible nozzle body which defines a flow-through volume through which a material can flow for the bead of material, which is partially delimited by a walling formed by the nozzle body, having a feed opening for feeding the material into the flow-through volume. The nozzle body defines a mouth region through which the material can exit from the volume. Furthermore, the device includes an actuator system, which is arranged on the nozzle body and is set up to change a cross section of the mouth region while deforming the nozzle body. The walling forms a barrier between the flow-through volume and the actuator system.

Abstract
A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

Abstract
An orthodontic teeth-straightener, comprising a splint element which contains, or is entirely made from, a thermoplastic polyurethane having shape-memory properties. The thermoplastic polyurethane having shape-memory properties is selected from the group of polyether polyurethanes and contains hard segments which contain polyurethane units that have been obtained by polyaddition of the isocyanate groups of a diisocyanate to the hydroxyl groups of a diol acting as a chain extender, thereby forming urethane groups. The polyether polyurethane also contains soft segments, which contain, or are entirely made from, polyether units in the form of polyalkylene glycols, wherein the polyether units are bonded to isocyanate end groups of the diisocyanate of the hard segments, thereby forming urethane groups with the hard segments. The thermoplastic polyether polyurethane is both thermo-responsive and water-responsive and thus gives the splint element dual-stimuli responsive shape-memory properties.

Abstract
In a method for producing pyrolysis oil, pyrolysis gas and pyrolysis coke, a starting material substantially comprising biomass is supplied to the upper region of a pyrolysis reactor. The latter has a substantially vertically arranged reactor chamber, which is substantially tubular. The reaction chamber then contains a bed of bulk material that comprises the starting material to be pyrolyzed and, optionally, the pyrolysis coke. This bulk material is thermally treated in the pyrolysis reactor, where the pyrolysis coke, the pyrolysis gases and the pyrolysis vapors are formed from the starting material to be pyrolyzed, and where the bulk material, the pyrolysis gases and the pyrolysis vapors are guided through the reaction chamber from top to bottom. The movement of the bulk material is caused substantially by gravity and the movement of the pyrolysis gases and pyrolysis vapors by the gas pressure building up.
