Title: Cyclin-dependent kinase inhibitors as plant growth regulators
Inventor: FOWKE LARRY C
IPC: C07K14/415
Filed: 1998-06-08
Abstract: Cyclin-dependent kinase (CDK) inhibitor genes encode low molecular weight proteins which have important functions in cell cycle regulation, development and perhaps also in tumorigenesis (Sherr and Roberts, 1995; Harper and Elledge, 1996). The first plant CDK inhibitor gene ICKI was recently identified from Arabidopsis thaliana (Wang et al., 1997). Although the C-terminal domain of ICK1 contained an important consensus sequence with the mammalian CDK inhibitor p27  KiP1, the remainder of the deduced ICK1 sequence showed little similarity to any known CDK inhibitors. In vitro assays showed that recombinant ICK1 exhibited unique kinase inhibitory properties. In the present study we characterized ICK1 in terms of its gene structure, its interaction with both Arabidopsis thaliana Cdc2a and cyclin 83 and its induction by the plant growth regulator, abscisic acid (ABA). ICK1 was expressed at a relatively low and uniform level in the tissues surveyed. However, ICKI was induced by, ABA, and along with ICKI induction there was a decrease in Cdc2-associated histone H1 kinase activity. These results suggest a molecular mechanism by which plant cell division might be inhibited by ABA.  ICKI clones were also identified from independent yeast two-hybrid screens using the cyclin .delta.3 construct. The implication that ICK1 protein could interact with both Cdc2a and cyclin .delta.3 was confirmed by in vitro binding assays. Furthermore, deletion analysis indicated that different regions of ICK1 are required for the interactions with Cdc2a and cyclin .delta.3. These results provide mechanistic basis for understanding the role of CDK inhibitors in cell cycle regulation in plant cells.

Title: Procede et dispositif destines a minimiser l'asymetrie
Inventor: MOLL HANS-CHRISTER
IPC: H04L1/02
Filed: 1997-01-17
Abstract: A une vitesse de transmission de signaux de 1 Gb/s, la "cadence binaire" est d'1 ns, ce qui correspond, dans la fibre optique, à une longueur binaire de l'ordre de 0,2 m. Etant donné que l'asymétrie ne doit pas dépasser un dixième d'une longueur binaire, ceci signifie que des différences de longueur entre plusieurs conducteurs d'une ligne de transmission ne peuvent excéder 2 cm. Dans le but de minimiser l'asymétrie, laquelle ne manque pas de se produire dans une ligne de transmission (1), on a formé cette ligne (1) en réunissant trois par trois les conducteurs (2) de celle-ci, afin de former un câble de type ruban ou câble plat, dans lequel les différences de longueur (5) entre lesdits conducteurs (2) de la ligne de transmission n'excèdent pas 2 cm. Lors de l'utilisation des câbles, on minimise l'asymétrie en faisant en sorte que des lignes de transmission, telles que par exemple des câbles de type ruban, plats, enroulés, et préalablement coupés aux longueurs précises et appropriées, comme par exemple des longueurs de 10, 20 ou 30 m, présentent, entre les différents conducteurs, une variation dimensionnelle maximale de longueur de l'ordre de ±1 cm.

Title: Method and apparatus for investigating earth formations
Inventor: ROSTHAL RICHARD A
IPC: G01V3/20
Filed: 1992-10-30
Abstract: Apparatus and method are disclosed for determining the resistivity of formations surrounding an earth borehole.          An electrically conductive metal body, such as a drill collar on a drill string, is movable through the borehole.  A transmitting toroidal coil antenna is disposed on the body and is energized to induce a current which travels in a path that includes the body and the formations.  An electrode is disposed on the body, and a first signal which depends on the electrical effect of the current on the electrode is measured to obtain an indication of the resistivity of the formations.          In a form of the invention, a second transmitting toroidal coil antenna establishes a second current in the body that travels in a path that includes the body and the formations, and a second signal is measured at the electrode.  A current monitor measures the axial current passing a monitor position on the body, to obtain a monitor current value.  A compensated indication of formation resistivity can then be obtained as a function of the first signal, the second signal, and the monitor current value.  A local communication system facilitates the ultimate communication of information to the earth's surface.

Title: Method, apparatus and system for compressing data
Inventor: ZADOR ANDREW MICHAEL
IPC: H04N19/94
Filed: 1997-06-25
Abstract: An apparatus and method for image data compression performs a modified zerotree coding on a range of absolute image values from the largest to a determined smaller absolute value, based upon file size or quality. If it is desired to maintain more detail in the image, then a vector quantizer codes the remaining values below this determined smaller value to zero, and lossless entropy coding is performed on the results of the two coding steps. The determined smaller value can be adjusted by examination of the histogram of the tree, or iteratively to meet a preselected compressed image size criterion or to meet a predefined level of image quality, as determined by any suitable metric. If the image to be compressed is in RGB color space, the apparatus converts the RGB image to a less redundant color space before commencing further processing.
