  • Publication number: 20230416592
    Abstract: Geopolymer precursor compositions are presented that are useful for cementing a subterranean well, among other uses. The precursor compositions are dry mixtures that have an aluminosilicate source and an activator. The activator is an alkalinity source that is safe to store, transport, and blend with an aluminosilicate source. The activator may be a hydroxide-free activator. A geopolymer slurry is formed by adding water to the dry geopolymer precursor compositions. Such slurries have suitable characteristics for use in cementing applications that use pumpable mixtures.

  • Publication number: 20190131161
    Abstract: A substrate handling apparatus is provided. The substrate handling apparatus may include a forked structure with one or more support portions which are arranged to provide access to a back surface of a substrate. The substrate handling apparatus may also include a first active support element and a second active support element configured to couple the substrate handling apparatus to the back surface of the substrate. After being placed on the first active support element and the second active support element, the substrate may tilt or lean to create at least a third, passive point of contact along the forked structure. The creation of at least a third, passive point of contact may increase substrate handling and control capabilities with warped substrates.

  • Publication number: 20070196851
    Abstract: Dependence between expression levels of different genes is identified through a multivariate method of statistical analysis of single color microarray gene expression data. An algorithm is applied to gene data to identify those genes that are likely to change their relationship with all other genes, and select such genes for further investigation. If genes change their relationship to other genes from phenotype to phenotype, they are treated as likely to change their relationship with one another.

  • Publication number: 20070117132
    Abstract: An amplification-like, unidirectional dependence between expression levels in gene pairs is identified through statistical analysis including a determination of whether there is a specified level of independence (or non-correlation) between X and Z, where X is a random variable representing the expression level of a first gene, Y is a random variable representing the expression level of a second gene, and Y=XZ where Z?1. The disclosed process provides an ability to identify genes that act as “amplifiers,” thereby facilitating appropriate priority assignment to candidate genes for further evaluation and experimentation.

  • Publication number: 20060088831
    Abstract: The present invention provides multivariate methods for identifying differentially expressed genes based on microarray expression data. An improved random search procedure involving certain probability distances is provided. The methods of this invention implement a successive elimination procedure to remove smaller subsets resulted from each step of the random search thereby establishing a larger set of differentially expressed genes.

  • Publication number: 20040265830
    Abstract: The present invention applies pattern recognition and multidimensional classification in statistical microarray data analysis. There are provided methods for identifying a subset of genes that are differentially expressed under a given biological state or at a given biological locale of interest by determining an advantageously large probability distance between the random vectors representing expression levels of the genes of interest. The invention also provides a cross-validated random search mechanism for a subset of genes based on various probability distances between two random vectors.
