Abstract: The methionine salvage pathway which is normally used to produce polyamines using ATP as a carbon source, can provide significant amounts of homoserine for use in biosynthesis of threonine, threonine derivatives and methionine precursors. Specifically, a cell is engineered to produce S-adenosylmethionine hydrolase, thereby providing a synthetic route to the above compounds which avoids feedback regulation upstream of homoserine, and which relies on a carbon source (ATP) that is replenished as a priority.

Abstract: The subject matter of the invention is a mounting for the connection of two skirting boards, whose mutually adjacent ends engage in two mounting grooves. A mounting of this type with stationary grooves with an oblique base forms the prior art. The disadvantage of this mounting is fixing it at a particular inside or outside angle and the necessity to bevel the ends of the board. The object of the invention is therefore to remove the rigidity of the angle between the limbs of the mounting and to dispense with bevelling. This object is achieved by the construction of the two grooves (26) in each case in one of two separate mounting parts (14 and 16) which can be rotated relative to each other about a vertical swivel axis (L) in each case through an angle of approximately 90 DEG . The advantage of this solution is being able to adjust each inside angle from 90 DEG  almost up to 180 DEG  and to cut the ends of the boards off straight. <IMAGE>

Abstract: An improved modulator network for an interpolative oversampled (sigma-delta) analog-to-digital converter comprises a second-order modulator (20), which performs double integration (22,24) of error between its digital output signal and its analog input signal, and a first-order modulator (30), which performs single integration (36) of error between its digital output signal and an analog signal supplied thereto from the second-order modulator. The modulators (20,30) supply their output signals to a digital error cancellation circuit (44,46,48) which suppresses in the signal supplied to a decimation filter (50) the quantization noise arising in the second-order modulator (20). The network exhibits significantly reduced sensitivity to the practical nonidealities that normally limit the resolution of analog-to-digital converters of this type, i.e., component matching, amplifier nonlinearity, finite gain, settling time, and signal dynamic range.

Abstract: In this invention there is disclosed a multi-stage optical fiber amplifier for providing a new function, that of gain equalization. The disclosed multi-stage optical fiber amplifier comprises at least two stages of amplification where each stage comprises an amplifying fiber having a different gain spectrum. In one embodiment the two stages, which can be pumped separately, have different dopant compositions to provide each stage with a different gain spectrum. The disclosed multi-stage optical fiber amplifier provides overall gain spectrum equalization of the amplified channels of long haul transmission lines. Typically, gain equalization can adjust the gain of one channel while maintaining the gain of a second channel constant. When used in combination with automatic gain control, the amplifier gain can be equalized dynamically to compensate for random variations in the relative optical power of wavelength-multiplexed signals to prevent system impairment caused by low-power channels.

Abstract: Symbols (a₁-a₁₆;b₁-b₁₆) of a transmitted signal in a digital cellular communication channel are interleaved to reduce the burst error rate caused by channel fading. The interleaving is skewed by partitioning the frames of the data into a plurality of subsets grouped in an irregular arrangement. This interleaving scheme skews the distribution of signal symbols so that individual symbols associated with individual originating codewords are distributed unequally in various transmitted groups of symbols. The various symbol subsets are separated by increased code and time distances to counteract the effects of fading.

Abstract: A long wavelength transmitter OEIC includes a transverse direction current injection type semiconductor laser and a high electron mobility transistor which are integrated on a semi-insulating substrate. The semiconductor laser includes at least an AlGaInAs lower cladding layer, a quantum well active layer and a high resistivity AlGaInAs upper cladding layer successively grown on the semi-insulating substrate, disordered regions formed in the quantum well active layer by diffusions of p type and n type dopant, and an active region sandwiched by the disordered regions. The transistor includes an operating layer and a carrier supplying layer both comprising AlGaInAs series material and formed on the high resistivity AlGaInAs upper cladding layer. This transistor uses the upper cladding layer as a leakage current preventing layer. This structure can be formed by only one epitaxial growth, resulting in low costs. In addition, since the above layers are successively grown on a flat substrate, photolithography process for forming a gate of HEMT can be performed on a flat surface, so that a fine gate pattern can be formed at high precision. As a result, a transmitter OEIC performing high speed modulation can be expected.
