Abstract: L'invention concerne des compositions cationiques et polycationiques, ainsi que des procédés pour améliorer la synthèse de molécules d'acide nucléique. Dans un mode de réalisation préféré, l'invention concerne l'inhibition ou la régulation de la synthèse, du séquençage ou de l'amplification d'acide nucléique. D'une manière spécifique, la présente invention porte sur des molécules, des composés et des compositions cationiques et polycationiques, présentant une affinité pour les molécules d'acide nucléique à double brin et/ou à simple brin et/ou les complexes d'acide nucléique à double brin/à simple brin (à savoir, les complexes amorce/matrice, les matrices à double brin, les matrices à simple brin ou les amorces à simple brin), pour l'utilisation dans une synthèse améliorée de ce type. Selon l'invention, les molécules, les composés et les compositions cationiques et polycationiques sont aptes à inhiber la synthèse d'acide nucléique non spécifique à température ambiante. Dans un mode de réalisation préféré, l'invention concerne la synthèse dite de "hot start" de molécules d'acide nucléique.

Title: Method of performing stretch-free normal movement(nmo) and stacking of seismic traces
Inventor: TRICKETT STEWART
IPC: G01V1/36
Filed: 2003-04-30
Abstract: A method of performing normal moveout (NMO) correction and stacking of a common-midpoint (CMP) gather of seismic traces in a manner that avoids NMO stretch is disclosed. A CMP gather without NMO correction is modeled as the sum of a series of short overlapping time intervals whose center times follow the NMO curve as it changes with offset. The sample values contained in these intervals axe solved simultaneously by performing a statistical fit to the CMP gather based on this model. A CMP stacked trace is formed by summing these intervals at their zero-offset positions at each time sample.

Title: Method and apparatus for interface-progressive video conversion
Inventor: TANG CHE WING
IPC: H04N7/01
Filed: 2001-08-29
Abstract: A method and apparatus for and correcting motion artifacts in interlaced video signal converted for progressive video display. To determine 3-2 pulldown or field motion, a video field is compared to the field prior to the previous field to generate field error. Field errors are generated for five consecutive fields and a local minimum error repeated every five fields indicate the origination of the video material from film source using the 3-2 pulldown process. Upon confirmation of 3-2 pulldown, the video material is modified to correct for the mixing of two film frames into one interlaced video frame by assuring that the two fields of the de-interlaced video frame contain data from the same film frame. Where the video material did not originate from a film source, but pixel motion is detected, the pixel motion is smoothed out by an averaging method. The odd and even fields of the resulting video data are subsequently combined to form a progressive video material.

Abstract: It is possible to provide a recorded matter or a sticker which can easily be checked to be a forged article or a genuine article but a user on market cannot see where and how the countermeasure against forging is arranged. On a surface of the same recording medium, there are arranged an overt area (recognizable on market) (3) printed by using a color changing ink or liquid crystal ink and a covert area (cannot be recognized unless a special instrument is used) (5) formed by retroreflective printing. The overt area (3) and the covert area (5) may be arranged at different places or overlapped partially or entirely. The overt character graphic pattern may be identical to or different from the covert character graphic pattern. In the case of overt printed by using liquid crystal ink, it also functions as a covert by using the authentication method employing a circular polarization plate. The sticker may have one or more cuts so that the sticker is broken when it is peeled off and cannot be used again.

Abstract: L'invention concerne un procédé permettant la détection de mutations et de polymorphismes d'un seul nucléotide (SNP : single nucleotide polymorphisms). Ce procédé repose sur l'utilisation de protéines de recombinase de type RecA et d'une protéine de liaison de mésappariement de type MutS. Des sondes oligonucléotidiques d'ADN spécifiques recouvertes de RecA (filaments Reca) sont utilisées pour la recherche d'homologies dans l'ADN double brin. La localisation de séquences homologues entraîne la formation de structures de boucle D contenant une région à double brin constituée de la sonde oligonucléotidique et d'un brin de l'ADN testé. Les mésappariements ou les bases non appariées de la région à double brin forment des substrats pour la liaison de MutS. Une co-localisation de MutS et de marqueurs oligonucléotidiques ou RecA indique des différences de séquence spécifiques entre la sonde et les ADN testés. L'invention concerne également des compositions et des coffrets servant à la mise en oeuvre des procédés décrits.
