摘要： Communication systems and methods in accordance with various embodiments of the invention utilize modulation on zeros. Carrier frequency offsets (CFO) can result in an unknown rotation of all zeros of a received signal's z-transform. Therefore, a binary MOCZ scheme (BMOCZ) can be utilized in which the modulated binary data is encoded using a cycling register code (e.g. CPC or ACPC), enabling receivers to determine cyclic shifts in the BMOCZ symbol resulting from a CFO. Receivers in accordance with several embodiments of the invention include decoders capable of decoding information bits from received discrete-time baseband signals by: estimating a timing offset for the received signal; determining a plurality of zeros of a z-transform of the received symbol; identifying zeros from. the plurality of zeros that encode received bits by correcting fractional rotations resulting from the CFO; and decoding information bits based upon the received bits using a cycling register code.

摘要： A method for controlling a combustion apparatus having a combustion state in which a parameter related to the combustion state reflects a chaotic behavior is provided. The method includes the steps of measuring the parameter and determining a time series of the parameter, shifting the time series by a variable time delay for determining a time-shifted signal, and forming a difference between the time-shifted signal and the time series for determining a time dependent first signal, so that a norm of the difference is lowest. A time dependent second signal is determined, wherein determining the time dependent second signal includes at least one of using a frequency of a desired oscillating combustion state, and shifting the time series by a set time delay. The first signal and the second signal are combined to determine a control signal. The control signal is used to influence the combustion apparatus.

摘要： The application relates to a method for zigzag folding a material web, the method having the following steps: continuously feeding a material web to be folded into a folding apparatus along a feed direction, alternately gripping the material web in a proximal region of the folding apparatus by means of gripping devices, holding and conveying the material web by means of the gripping devices into a distal region of the folding apparatus, the material web being zigzag folded thereby, and releasing the material web from the gripping devices and depositing the material web in a stack (9) with folds in the distal region, a distance between adjacent gripping devices (4, 5) being equal to a fold length. Furthermore, the application also relates to an apparatus for zigzag folding a material web.

摘要： Disclosed is a mussel adhesive protein including at least one photocaged 3,4-dihydroxyphenylalanine derivative residue including a protecting group on at least one hydroxyl residue of its catechol moiety. The photocaged 3,4-dihydroxyphenylalanine derivative residue replaces a naturally occurring amino acid and the protecting group can be cleaved from the 3,4-dihydroxyphenylalanine derivative residue by irradiation with UV light.

摘要： The present invention relates to a method for producing a recombinant polypeptide of interest in a microbial host cell, comprising (a) introducing a polynucleotide encoding the polypeptide of interest into a microbial host cell which has been modified such that an enzymatic activity selected from the group consisting of ketol-acid reductoisomerase (NADP(+)) activity (EC 1.1.1.86), acetohydroxyacid synthase activity (EC 2.2.1.6), aspartate kinase activity (EC 2.7.2.4), homoserine dehydrogenase activity (EC 1.1.1.3), and L-threonine dehydratase activity (EC 4.3.1.19) is modulated in said microbial host cell as compared to the enzymatic activity in an unmodified microbial host cell, and (b) expressing said polypeptide of interest in said microbial host cell. Moreover, the present invention relates to a method for reducing misincorporation of at least one non-canonical branched-chain amino acid into a recombinant polypeptide of interest expressed in a microbial host cell.

摘要： The invention relates, inter alia, to an optical semiconductor amplifier (10), in which a plurality of quantum dots (QD) are arranged in at least one quantum dot layer (21-24) of a semiconductor element (11) of the semiconductor amplifier (10), wherein die semiconductor element (11) has a preferred direction (X) located in the quantum dot layer plane, and elongated quantum dots (QD) are present, each of which is longer in the said preferred direction (X) than in a transverse direction (Y) perpendicular thereto and is likewise located in the quantum dot layer plane. According to the invention, the beam amplification direction (SVR) of die semiconductor amplifier (10), which is defined by a fictitious connecting line (VL) between an input (A10) of the semiconductor amplifier (10) that serves for the irradiation of input radiation (Se), and an output (A10) of the semiconductor amplifier (10) that serves for outputting the amplified radiation (Sa), is arranged parallel, or at least approximately parallel, to the transverse direction (Y).

摘要： The invention relates to a locking coupling including a first coupling unit and a second coupling unit, which in each case extend along a longitudinal axis and are designed to be identical. Each coupling unit includes a valve unit and a locking unit. The first and the second valve unit are designed to form a fluid connection between the first and the second coupling unit, and the first and the second locking unit are designed to connect the first coupling unit and the second coupling unit mechanically to one another. The first coupling unit includes an actuating element, by actuation of which the first and the second coupling unit can be mechanically connected to one another via the first and the second locking unit and can be fluidically connected to one another via the first and the second valve unit.
