  • Publication number: 20240176763
    Abstract: Techniques for accessing data objects using UDF streams include decoding by at least one hardware processor of a first computing node, a first request for a UDF. The first request is generated at a second computing node by one of a plurality of input streams of the UDF. A second request for one or more data objects associated with the UDF is generated at the first computing node using an execution thread assigned to the first request. An authorization of the execution thread is performed using data access rights assigned to the first request. The one or more data objects are retrieved based on the authorization in response to the second request. The one or more data objects are stored in a storage location accessible by the execution thread.

  • Patent number: 11992644
    Abstract: A system for accessing a patient's vascular system may have a tube with a wall that defines an exterior surface and lumen with a proximal end and a distal end, and a guidewire that is deployable, by sliding distally, from a retracted position in which the guidewire resides in the lumen, to a deployed position in which the guidewire extends beyond the distal end. The system may further have a retraction mechanism that can be actuated to retract the guidewire from the deployed position to the retracted position, or a protective shield that can be actuated to extend distally from the distal end of the tube to cover the guidewire in the deployed position.

  • Publication number: 20240165681
    Abstract: Various embodiments of the present technology may provide methods and apparatus for cleaning a source vessel. The source vessel may be filled or partially filled with a solvent to form a solution. The solution is removed from the source vessel and contained in a waste vessel that is connected to the source vessel. The waste vessel may have a bellow or other mechanism inside of it to create a negative pressure in the waste vessel to pull the solution out of the source vessel and into the waste vessel. Alternatively, a liquid pump may be used to pull the solution from the source vessel to the waste vessel.

  • Publication number: 20240114138
    Abstract: In transform coefficient coding, predetermined sets of transforms may be used. Embodiments of the present invention provide an encoder and a decoder for encoding a picture into/from a data stream using block-based prediction and block-based residual coding, the encoder and decoder supporting a set of transforms for the block-based residual coding. The encoder and decoder are configured to determine a transform candidate list of transforms for a current residual block out of the set of transforms based on a height and a width of the current residual block, and to encode/decode a prediction residual within the residual block using one selected transform out of the selectable list of transforms and selectively signal/derive the selected transform in/from the data stream.

  • Patent number: 11931483
    Abstract: Inserts can be formed with elution characteristics to cause the inserts to elute an antimicrobial agent when subject to a fluid within a medical device. An insert can be formed with a desired geometry to allow the insert to be compression fit within a medical device to prevent the insert from moving or becoming dislodged once inserted into the medical device. The material may also be hygroscopic so that the insert swells when subject to a fluid thereby enhancing the compression fit of the device within the medical device. In some cases, the material can be reinforced using an internal structure. Inserts can be formed in many ways including by casting, thermoforming, or extrusion. In some cases, the inserts can be formed using a peel-away sleeve or material. The peel-away sleeves can be formed of a non-sticky material which facilitates removal of the inserts once the inserts have cured.

  • Publication number: 20230159913
    Abstract: The disclosure provides methods of deaminating adenosine and cytosine bases in a target nucleic acid sequence in an USH2A gene comprising contacting the USH2A gene with a base editor in association with a guide RNA (gRNA). In some aspects, base editing is used to restore US2HA function by disrupting a splice site in the USH2A gene sequence to induce skipping of an exon containing a mutation, while in other embodiments, base editing is used to restore US2HA function by correcting a point mutation e.g., in an exon) so as to correct mutations. The disclosure also provides complexes of adenosine base editors and guide RNAs, and complexes of cytidine base editors and guide RNAs. The disclosure further provides pharmaceutical compositions and cells comprising these complexes. The disclosure also provides vectors encoding these complexes, base editors, and gRNAs. In some embodiments, the methods and compositions provided herein are used to treat Usher syndrome and autosomal recessive retinitis pigmentosa (arRP).

  • Publication number: 20220249697
    Abstract: Provided herein are methods of delivering “split” Cas9 protein or nucleobase editors into a cell, e.g., via a recombinant adeno-associated vims (rAAV), to form a complete and functional Cas9 protein or nucleobase editor. The Cas9 protein or the nucleobase editor is split into two sections, each fused with one part of an intein system (e.g., intein-N and intein-C encoded by the dnaE-n and dnaE-c genes, respectively). Upon co-expression, the two sections of the Cas9 protein or nucleobase editor are ligated together via intein-mediated protein splicing. Nucleic acid molecules encoding the N-terminal portion of a Cas9 protein or a nucleobase editor fused to an intein, and nucleic acid molecules encoding the C-terminal portion of a Cas9 protein or nucleobase editor, are provided.

  • Patent number: 10827014
    Abstract: An online system predicts the user's activity on the online system during a future time interval (e.g., the next day). The system collects activity data, such as actions that the user has taken on the system. The system predicts whether the user is likely to be active during the future time interval based on features extracted from the activity data. This system determines selection of notifications and delivery of notifications based on the predicted time when the user is likely to be active on the online system. The system further records the user's past interactions with notifications, such as whether the user viewed the notification, whether the user interacted with a content item associated with the notification, and so on. If system determines a rate of delivery of notifications to the user based on the frequency of past user interactions with notifications.
