At least two of such wheels may be attached to one vehicle and coordinated. A wheel strut is attached to the wheel using an attachment that is rotatable about its longitudinal axis. The wheel strut is able to rotate the wheel using the attachment.
Abstract: A method and an apparatus relating to a fine frequency synchronization compensating for a carrier frequency deviation from an oscillator frequency in a multi-carrier demodulation system of the type capable of carrying out a differential phase decoding of multi-carrier modulated signals, the signals comprising a plurality of symbols, each symbol being defined by phase differences between simultaneous carriers having different frequencies. A phase difference between phases of the same carrier in different symbols is determined. Thereafter, a frequency offset is determined by eliminating phase shift uncertainties related to the transmitted information from the phase difference making use of a M-PSK decision device. Finally, a feedback correction of the carrier frequency deviation is performed based on the determined frequency offset. Alternatively, an averaged frequency offset can be determined by averaging determined frequency offsets of a plurality of carriers.

Abstract: The invention is used in the field of materials engineering and relates to a method for defining reference magnetizations which could be used, for example, in magnetic sensor technology components. The object of the present invention is to disclose a method for defining reference magnetizations in layer systems, whereby the reference directions can be selected as desired with regard to number and spatial direction. The object is attained through a method for defining reference magnetizations in layer systems in which at least one layer system is produced by geometrically structuring a hard-magnetic and/or soft-magnetic layer and by applying the hard-magnetic and/or soft magnetic layer to at least one antiferromagnetic layer before, during or after a single-stage or multi-stage thermal treatment, whereby the temperature is increased at least to a temperature greater than the coupling temperature and the layer system is cooled afterwards.

Abstract: The invention is directed to a method of producing the material that is unaffected by the low-temperature degradation, humidity-enhanced phase transformation typical of yttria-stabilized zirconia, as well as of yttria-stabilized tetragonal zirconia polycrystalline ceramic (Y-TZP). Because of the high fracture toughness and high mechanical strength, this class of materials is widely used, including as implants, such as for the packaging material for small implantable neural-muscular sensors and stimulators. The destructive phase transformation rate is dramatically reduced by coating the surface of the Y-TZP component with dense alumina by a physical vapor deposition process, preferably ion beam assisted deposition.

Abstract: The invention is directed to a method of producing the material that is unaffected by the low-temperature degradation, humidity-enhanced phase transformation typical of yttria-stabilized zirconia in general, as well as of yttria-stabilized tetragonal zirconia polycrystalline ceramic (Y-TZP). Because of the high fracture toughness and high mechanical strength, this class of materials is widely used, including as implants, such as for the packaging material for small implantable neural-muscular sensors and stimulators. The destructive phase transformation is eliminated by converting the surface to stable cubic or T-prime zirconia by post-densification thermal treatment in a cation-rich milieu.

Abstract: Double-stranded RNA (dsRNA) induces sequence-specific post-transcriptional gene silencing in many organisms by a process known as RNA interference (RNAi). Using a Drosophila in vitro system, we demonstrate that 19–23 nt short RNA fragments are the sequence-specific mediators of RNAi. The short interfering RNAs (siRNAs) are generated by an RNase III-like processing reaction from long dsRNA. Chemically synthesized siRNA duplexes with overhanging 3? ends mediate efficient target RNA cleavage in the lysate, and the cleavage site is located near the center of the region spanned by the guiding siRNA. Furthermore, we provide evidence that the direction of dsRNA processing determines whether sense or antisense target RNA can be cleaved by the produced siRNP complex.
