  • Patent number: 12237051
    Abstract: A system for indexing, updating, and search haplotypes for genetic genealogical discovery in genotype databases. The system includes a pool of genetic indexes, a haplotype ingestion engine, and a haplotype query engine. The haplotypes of a number of individuals in a genotype database are indexed by a pool of multiple panels, and each panel pool can be dynamically updated by the insertion or deletion of individual haplotypes. A genetic genealogical search of a query haplotype against the database is achieved by first projecting the query onto a subset of panels in the pool, then conducting long match queries over each panel, and finally aggregating the identified long matches into Identical-by-Descent segments, i.e., DNA matches, between the query and the haplotypes in the database.

  • Publication number: 20080132648
    Abstract: The present invention provides a process for converting free hydroxyl groups of polyoxyalkylene glycols and/or polyoxyalkylene glycol monoethers by reacting at least one polyoxyalkylene glycol or at least one polyoxyalkylene glycol monoether with a base, and then alkylating or acylating it with a halohydrocarbon or acid halide in the presence of a reducing agent, the alkylation or acylation reaction being performed in the presence of atmospheric oxygen.

  • Publication number: 20060199980
    Abstract: The invention relates to a process for preparing alkylene glycols by hydration of alkylene oxides in the presence of polyalkylene glycol dialkyl ethers of the formula R1—O—[—(CH2CH2O)m(CH(CH3)CH2)—O]n—R2 in which m=0-100, n=0-100, where n+m is at least equal to 1, R1 is a C1- to C6-alkyl radical, R2 is a C1- to C6-alkyl radical, where R2 may be different from R1, with the proviso that for at least 50 mol % of the polyalkylene glycol dialkyl ether m+n is greater than or equal to 11.
