The polymeric matrix contains 10% by weight or more of the one or more polymer(s). The one or more polymer(s) are polymerized from a monomer mixture containing the monomers (a) 70 to 95% by weight of 2-ethylhexyl methacrylate (EHMA) and ethyl methacrylate (EMA), or 2-ethylhexyl methacrylate (EHMA) and methyl methacrylate (MMA); (b) 0 to 25% by weight of a C2 to C6 hydroxy-alkylester of acrylic acid or methacrylic acid; and (c) 2.5 to 20% by weight of a C2 to C8 alkyl ester of acrylic acid or of methacrylic acid with a quaternary cationic group in the alkyl group.

Abstract: A process for preparing polymeric particles involves a stepwise or gradient emulsion polymerization. The polymeric particles contain polymerized units of methacrylic acid and further monomers, with an overall monomer composition by weight of polymerized units of 5 to 25% by weight of methacrylic acid and 75 to 95% by weight of further monomers. The further monomers are selected from C1- to C4-alkylesters of methacrylic acid and/or C1- to C4-alkylesters of acrylic acid. The ratio by weight of polymerized units of methacrylic acid to further monomers increases stepwise or in a gradient from the center to the surface of the particles and the polymeric particles are obtained in the form of an aqueous dispersion.

Polymer 2 is polymerized from (a2) 70-95 wt. % of C1-C12 alkylester of (meth)acrylic acid, and (c2) 5-30 wt. % of C2-C6 hydroxy-alkylester of (meth)acrylic acid. Monomers (a1) and (b1) add up to 98-100 wt. %, and most preferred to 100 wt. %. Monomers (a2) and (c2) add up to 98-100 wt. %, most preferred to 100 wt %.

Abstract: Compound, stereoisomers, enantiomers or diastereomers thereof, physiologically acceptable salts thereof, mixtures of said compound for use in increasing mental capability, and a pharmaceutical composition. The increasing of mental capability is tested in learning experiments with Drosophila melanogaster larvae or older animals, which are raised with standard feed mash or with different concentrations of FSE-20 in the feed mash. In the learning experiment, the animals are each subjected to one of two inverse training regimens and then subjected to a test. In the training, a first scent was presented with the feed reward to the first group, while a second scent was presented alone to the first group. The second group was trained inversely. In the test of the learning experiment, it was subsequently examined whether the larvae of both groups prefer the first scent or the second scent in a selection situation; thus, their learning and memory capability was determined.

The polymer is useful for preparing a dosage form with a sustained release profile and resistance against the influence of ethanol.

Abstract: Methods and apparatus are described for inserting data in a communications system, such as in an existing analog communications system, using quadrature amplitude modulation (QAM) with in-phase analog signals and quadrature data signals. These methods can minimize the distortion to the analog signals while maximizing the data signal strength. The data signals may be sub-modulated on a subcarrier frequency (201) such that the data signals do not interfere with the analog signal detectors in the analog signal receivers, and may be processed with an abatement filter (202) to mitigate the distortion due to Nyquist mismatch in the receiver. The injection phase of data signals may be determined (206) by adaptive algorithms, using a monitor analog signal receiver (103).

Abstract: Methods and apparatus for remote antenna subsystems that are physically isolated from receiver subsystems are disclosed. The communication between the two subsystems uses remote communication links. The remote communication links are either wireless, in which case they are designed for indoor low power communications, or are wired, using existing infrastructure in the household such as the power lines. Partitioning between the antenna and receiver subsystems is selectable.

Abstract: Compensation methods and apparatus are disclosed for mitigating non-linear distortion of high power amplifiers used in communication transmitters, based on the minimization of the symbol error, in particular, for communication systems transmitting data embedded in existing co-channel signals. To overcome the difficulty of constructing pre-distortion mapping from the symbol error, an adaptive algorithm is disclosed to update compensation parameters for pre-distortion mapping. Another method exploits a test signal interval in the co-channel signal. During a known constant co-channel signal, distortion is estimated as a complex number and used to construct compensation parameters. The latter is further expanded by employing the adaptive algorithm for the non-test signal intervals.

Abstract: A decision feedback equalizer (DFE) architecture uses feedback samples that are over-sampled with respect to the symbol rate. On-baud feedback samples are quantized with a slicer, while off-baud samples are linear, IIR samples. Both forward and feedback filters are fractionally-spaced, but adapted only at the baud instances.
