Abstract: Compositions that are plants, seeds or crops that have a combination of defective BADC genes and genes for making hydroxy fatty acids produced normal levels of oil containing specialty fatty acids, and exhibited an increases in total oil accumulation, increase in absolute hydroxy (specialized) fatty acid accumulation per seed and/or per plant and/or per unit land area. Defective BADC genes and genes for synthesizing hydroxy fatty acids are combined to produce specialized fatty acids without substantially slowing production of endogenous fatty acids. Methods are also described for increasing production of unusual fatty acids and increasing total fatty acid levels in plants by a mechanism involving combining defective BADC genes and genes for making hydroxy fatty acids to produce steady or increased levels of oil containing the increased specialty products as described herein.

Abstract: Electrical detection methods are used to identify and further characterize single-molecule target analytes such as proteins and nucleic acids. A composition including a probe region and a tail region is contacted with a target analyte. The probe region specifically binds to the target analyte. The tail region is coupled to the probe region, and includes a nucleic acid template for polynucleotide synthesis. When conditions are such that polynucleotide synthesis occurs along the tail region, one hydrogen ion is released for every nucleotide that is incorporated into the tail region. A transistor such as an ISFET detects and measures changes in ion concentration, and these measurements can be used to identify the tail region and thus characterize the corresponding target analyte.

Abstract: A magnetic fluid sealing device, includes first pole teeth and a first magnetic fluid adsorbed on the first pole teeth functioning as a first line of defense for sealing, as well as second pole teeth and a second magnetic fluid adsorbed on the second pole teeth functioning as a second line of defense for sealing. The second pole teeth of the magnetic fluid sealing device are arranged on the permanent magnet or the flux sleeve. Since the flux sleeve is fitted over the permanent magnet, the arrangement of the second pole teeth can ensure the ability of the pole shoe to absorb the magnetic fluid, and also can make full use of a length of the permanent magnet in the axial direction of the rotating shaft. Therefore, the magnetic fluid sealing device is effectively improved in the sealing effect and the pressure resistance without increasing its axial length.

Abstract: Example embodiments relate to GNSS time synchronization in redundant systems. A redundant system configured with two subsystems may initially synchronize clocks from both subsystems to GNSS time from a GNSS receiver. The synchronization of the first subsystem's clock may involve using a first communication link that enables communication between the first subsystem and the GNSS receiver while the synchronization of the second subsystem's clock may involve using both the first communication link and a second communication link that enables communication between the subsystems. The redundant system may then synchronize the first subsystem's clock to the second subsystem's clock while the second subsystem's clock is still synchronized to GNSS time from the GNSS receiver based on timepulses traversing a pair of wires that connect the subsystems and the GNSS receiver.
