Title: Biosynthesis of cmp-legionaminic acid from fructose-6-p, and respective pathway intermediates, using novel gdp-linked precursors
Inventor: SCHOENHOFEN IAN C
IPC: C12P19/32
Filed: 2009-12-16
Granted: 2018-09-25
Abstract: The sialic acid-like sugar legionaminic acid is found as a virulence-associated surface glyco-conjugate in Legionella pneumophila and Campylobac-ter coli. In this work, we have purified and biochemical-ly characterized eleven candidate biosynthetic enzymes from C. jejuni, thereby fully reconstituting the biosyn-thesis of legionaminic acid and its CMP-activated form, starting from fructose-6-P. This pathway involves unique GDP-linked intermediates and provides a facile means for the efficient large-scale synthesis of an im-portant sialic acid mimic and novel precursors.

Abstract: A system for shifting energy demand from on-peak time windows to off-peak time windows by using hot water heater load shifting, while providing the end user with the level of service (i.e., availability of hot water) according to the user's customary use described by service quality criteria. The shift is accomplished by a controller located at the end user establishment and in communication with a central control server. The controller monitors local water heater upper and/or lower temperature and controls upper and/or lower water heater heating elements in accordance with a demand shift process commanded by the central control server. The controller may determine usage and remaining capacity for reporting back to the central control server. A volumetric capacity and usage determination is disclosed. The control server may select water heaters according to use patterns and/or measured capacity. One embodiment is adapted for use with existing water heaters without disrupting safety features of the existing water heater.

Abstract: Known systems for automatic height control of a dozer blade (302), which rotates about a line through pivot points (304) for supporting arms (303) when it changes its height use feedback and a reference from an absolute blade height measuring system (306). This only permits a slow operation. According to the invention the input from the slow absolute height sensor (306) is combined with an input from a fast gyroscope (307 or 308) that measures the instant rotation and recalculates it into a vertical height change using the length (309) of the supporting arms as the basis. The combination obtains the accuracy of the infrequent absolute height information and an increased speed of measurement resulting in a compensated height estimate that is input to a hydraulic control system of the feedback type. This improved height feedback enables much more aggressive control even though the hydraulic system has an unknown linearity and delay associated with it. The gyroscopic sensor forms an IMU (307 or 308) with one degree of freedom to compensate for the inevitable drawbacks of the absolute height sensor (306) in use with regard to delay, noise and update rate to obtain a frequent, time-correct height position with a reduced level of noise by means of a calculation based on both types of sensor output.

Abstract: La présente invention concerne des techniques pour effectuer un codage et décodage entropique de coefficients vidéo à l'aide d'un modèle de contexte joint partagé entre des unités de transformation ayant des tailles différentes. Par exemple, le modèle de contexte joint peut être partagé entre des unités de transformation ayant une première taille de 32x32 et des unités de transformation ayant une seconde taille de 16x16. L'exécution d'un codage entropique à l'aide d'un modèle de contexte joint partagé entre des unités de transformation ayant des tailles différentes peut réduire une quantité de mémoire nécessaire pour stocker des contextes et des probabilités, et peut réduire des coûts de calcul pour la maintenance des modèles de contexte. Dans un exemple, le modèle de contexte joint peut être partagé entre des unités de transformation ayant la première taille avec des coefficients mis à zéro afin de générer un bloc de coefficients non distribués ayant la seconde taille et des unités de transformation ayant la seconde taille. Dans un autre exemple, le modèle de contexte joint peut être partagé entre des unités de transformation ayant la première taille et des unités de transformation ayant la seconde taille.
