  • Publication number: 20240124502
    Abstract: Organometallic complexes are described which are useful as pre-polymerization catalysts which may form part of olefin polymerization catalyst systems. The catalyst systems find use in the polymerization of ethylene, optionally with one or more C3-12 alpha-olefin comonomers. The organometallic complexes are broadly represented by formula I: wherein L is a bridging group containing a contiguous chain of atoms connecting P with Cy, wherein the contiguous chain contains 2 or 3 atoms and wherein Cy is a cyclopentadienyl-type ligand. The olefin polymerization catalyst system is effective at polymerizing ethylene with alpha-olefins in a solution phase polymerization process at high temperatures and produces ethylene copolymers with high molecular weight and high degrees of alpha-olefin incorporation. Pre-metallation compounds, metallation processes and synthetic methods to make the organometallic complexes as well as polymerization processes are also described.

  • Publication number: 20240086335
    Abstract: Techniques for providing increased support for deduplication and compression of encrypted storage volumes. The techniques include receiving, at a storage virtual machine (VM), a data encryption key (DEK) associated with encrypted volume data, in which the DEK is wrapped in a key encryption key (KEK). The techniques include receiving, at the storage VM from a client virtual machine (VM), a write request specifying the encrypted volume data. The techniques include obtaining, by the storage VM, the KEK from a key management system (KMS) embedded on the storage VM. The techniques include unwrapping, by the storage VM, the DEK using the KEK, and decrypting, by an IO decryptor hosted by the storage VM, the encrypted volume data using the DEK. The techniques include performing, by the storage VM, data reduction operations on the decrypted volume data, and storing, by the storage VM, the data-reduced volume data on a storage array.

  • Publication number: 20230159986
    Abstract: The disclosure provides methods for characterizing a target DNA present in a sample. The methods involve contacting the sample with one or more universal primers to amplify target DNA; contacting the amplified target DNA with a type V CRISPR/Cas effector protein and one or more guide RNAs, where the contacting generates a cleavage product comprising a 5? overhang; and ligating a double-stranded nucleic acid adapter to the cleavage product, to generate a ligation product. The ligation product includes the target DNA, which can be sequenced. The sample can be subjected to one or more amplification steps prior to the contacting step, with primers that provide for amplification of nucleic acids of, e.g., specific pathogens, categories of pathogens, two or more different pathogens, or two or more different categories of pathogens.

  • Patent number: 11515006
    Abstract: Embodiments are directed to systems and methods for pathogen detection using next-generation sequencing (NGS) analysis of a sample. Embodiments may apply alignment algorithms (e.g., SNAP and/or RAPSearch alignment algorithms) to align individual sequence reads from a sample in a next-generation sequencing (NGS) dataset against reference genome entries in a classified reference genome database. Embodiments of the present invention may include classifying, filtering, and displaying results to a clinician that can then quickly and easily obtain the results of the sequencing to identify a pathogen or other genetic material in a sample that is being tested. A negative sample and a corresponding database can be used to remove contaminants from a list of candidate pathogens. Thus, embodiments are directed to a system that is configured to filter the results of a sequencing alignment and classify a sample quickly.
