  • Publication number: 20240161867
    Abstract: One or more techniques for optimizing cancer classification based on covariate characteristics is disclosed. In a first approach, an analytics system may determine separate cutoff thresholds for positively detecting disease signal for different labels for a covariate characteristic. The system may subdivide training samples based on their labels for the covariate characteristic, to separately determine the cutoff thresholds. In other approaches, the system may train disparate classifiers for each population. The system separates the training samples based on their labels for the covariate characteristic, and separately trains classifiers to generate a signal vector representing an amount of disease signal detected in a sample. The classifiers may be trained on different feature sets as determined based on mutual information gain, genomic region coverage, and healthy activation fraction.

  • Publication number: 20240133288
    Abstract: A system can receive data relating to a tubular of a well system. The system can execute a first module to determine first outputs. The system can execute a second module to determine second outputs based on the first outputs. The system can execute a third module to determine third outputs based on the first outputs. The second outputs can include a crack-initiation fracture pressure, and the third outputs can include a crack-propagation fracture pressure. The system can identify a brittle-burst strength of the tubular from among the second outputs, the third outputs, and a standard burst strength of the tubular. The system can provide the brittle-burst strength of the tubular to facilitate an adjustment to the tubular to optimize a wellbore operation associated with the well system.

  • Patent number: 11959054
    Abstract: The present disclosure relates to a substrate apparatus (and methods of manufacturing the same) with one or more substrates having a substrate spacing for growing a cell mass. In particular embodiments, the disclosed substrate apparatus includes a substrate wound into a coiled configuration with an intra-coil spacing between coil layers. To provide the intra-coil spacing, certain implementations use a separator. For example, a separator is applied to a substrate surface, and the separator-substrate combination is wound together (e.g., around a spool). In turn, a locking element is attached to the substrate to maintain the coiled configuration. The separator is then removed via heat treatment, chemical treatment, or physical displacement—thereby leaving the intra-coil spacing between the coil layers. Alternatively, no separator is used to provide a substrate spacing. For example, in lieu of a separator, the locking element is actively applied to the substrate during the winding process.

  • Publication number: 20240102376
    Abstract: A system can generate, via a software model, downhole pressure estimations and downhole debris estimations using caving parameters. Additionally, the system can generate, via the software model, settled caving volume percent estimations using the caving parameters. The system can determine a pack off volume percent using the downhole pressure estimations, the downhole debris estimations, and the settled caving volume percent estimations. The system can output, via a user interface, the pack off indicator and a subset of the caving parameters for use in adjusting a wellbore operation. The user interface can provide a plot of the pack off volume percent horizontally offset with respect to a plot of the subset of the caving parameters and a depth of the wellbore.

The lower blocks are connected to each other and the adjustable support assembly by an angled lower block bracket. The upper block is attached to the lower blocks by spring-loaded hinges, such that the upper block is urged toward the lower blocks to grasp an object therebetween. The light-duty object collecting head is a chain-based head, while the heavy-duty object collecting head is a roller-based head.

  • Publication number: 20190127193
    Abstract: The elevating lift with a stabilized movable base includes a base with extendable legs that provide minimum to maximum adjustable stability during use and transport. A lift system is mounted on the base, and a platform assembly is mounted on top of the lift system for selective raising or lowering. Each extendable leg supports a caster, rendering the base movable, and selective extension and retraction of the legs adjusts the stability of the lift. The plurality of legs can be further driven to simultaneously rotate about the vertical axis to steer the lift. The stabilized movable base is further alternatively used in combination with a stool, providing minimum to maximum stability during use and transport of seating, and multiple to elevating lifts may be used to support linked platform assemblies in various configurations.

  • Patent number: 7885546
    Abstract: A method and apparatus for multiplexing multiple Ethernet-based data streams in an optical network reduce the number of optical transceivers required by the optical network. Multiple data streams are multiplexed into a combined data stream, transmitted from a node in the optical network as the combined data stream, and demultiplexed at the receiving node. Data streams are multiplexed and demultiplexed at the bit level, and packets from each data stream are routed based on a VLAN tag that is contained in the header of each packet. By transmitting the information contained in multiple data streams as a single multiplexed data stream, the number of optical transceivers required for the optical network may be reduced by more than half. An optical supervisory channel may also be bundled with one of the data streams to eliminate the need for a dedicated transceiver for the optical supervisory channel.

  • Patent number: 7834881
    Abstract: An apparatus and method for simulating a multi-ported memory using lower port count memories as banks. A collector units gather source operands from the banks as needed to process program instructions. The collector units also gather constants that are used as operands. When all of the source operands needed to process a program instruction have been gathered, a collector unit outputs the source operands to an execution unit while avoiding writeback conflicts to registers specified by the program instruction that may be accessed by other execution units.

  • Patent number: 7680988
    Abstract: A shared memory is usable by concurrent threads in a multithreaded processor, with any addressable storage location in the shared memory being readable and writeable by any of the threads. Processing engines that execute the threads are coupled to the shared memory via an interconnect that transfers data in only one direction (e.g., from the shared memory to the processing engines); the same interconnect supports both read and write operations. The interconnect advantageously supports multiple parallel read or write operations.
