Abstract: A computer-implemented method according to one embodiment includes establishing, for each hop in pathways of a network, a relation between a desired reliability and channel error. Based on the established relations, a maximum number of copies of packets to send from a source in the network to a target in the network is determined. An overhead associated with sending packets from the source to the target in the network is determined for each of the hops, and a first sum of such overheads is also determined. An overhead associated with sending an acknowledgement packet to the source is determined for each of the hops. A second sum is a sum of the overheads associated with sending the acknowledgement packet to the source. In response to a determination that a sum of the first sum and the second sum is less than a predetermined threshold value, the pathways are used.

Abstract: Unconventional hydrocarbon source rock reservoirs can contain the organic material kerogen, intertwined with the rock matrix. The kerogen can alter the tensile strength of the rock and contribute to higher fracture energy needs. To degrade kerogen and other organic materials, oxidizing gasses are dissolved in carbon dioxide (CO2) which is then used as part of a fracturing fluid. The oxidizing gasses can be dissolved directly in the CO2 or generated in situ using precursors.

The processor may also be configured to store the encoded dependency in the dependency matrix and dispatch instructions in the instruction buffer based at least on decoding one or more dependencies stored in the dependency matrix for the instructions. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method of forming an isocyanate-functional polymer component includes forming a first mixture by mixing a recycled polyurethane article and a first isocyanate component having isocyanate-functional groups. The first mixture is heated to a temperature sufficient to transform the recycled polyurethane article from a solid form to a liquid form and react the liquid recycled polyurethane component with the first isocyanate component to form an isocyanate-functional polymer component having an isocyanate-functional group content greater than zero and less than isocyanate-functional group content of the first isocyanate component. The formed isocyanate-functional polymer component may then be used for forming a polyurethane article or polyurethane foam article that is the reaction product of the formed isocyanate-functional polymer component, a second isocyanate component and an isocyanate-reactive component having hydroxyl-functional groups.

Abstract: A three-dimensional memory array may include a first memory array and a second memory array, stacked above the first. Some memory cells of the first array may be coupled to a first layer selector transistor, while some memory cells of the second array may be coupled to a second layer selector transistor. The first and second layer selector transistor may be coupled to one another and to a peripheral circuit that controls operation of the first and/or second memory arrays. A different layer selector transistor may be used for each row of memory cells of a given memory array and/or for each column of memory cells of a given memory array. Such designs may allow increasing density of memory cells in a memory array having a given footprint area, or, conversely, reducing the footprint area of the memory array with a given memory cell density.

Abstract: Disclosed is an improved approach to implement cursor sharing in database systems, where a server-side mapping of cursor identifiers to SQL is maintained to allow for continued use of client-side statement caches even after connections and database sessions are returned to shared pools and then subsequently re-assigned. This avoids the need to clear the statement cache across session releases to the database session pools. Instead, applications can retain their statement cache while still leveraging the benefits of server based pooling solutions.

Abstract: A method includes introducing a fluoro-based small molecule tracer into a stimulation fluid, injecting the stimulation fluid into a target zone of a subterranean formation, and maintaining the fluoro-based small molecule tracer inside the target zone of the subterranean formation for an amount of time. While being maintained inside the target zone, the fluoro-based small molecule tracer comes into contact with water at a downhole temperature resulting in hydrolysis of the fluoro-based small molecule tracer to produce a fluorinated tracer and a nonfluorinated group. Then, produced fluid that includes the fluorinated tracer is recovered, a concentration of the fluorinated tracer in the hydrocarbons is determined, and the concentration of the fluorinated tracer is correlated to a productivity of the target zone of the subterranean formation.

Abstract: Methods, systems, and devices for data management are described. A server hosted by a storage node within a cluster of a data management system (DMS) may receive a request to access a file stored in a distributed file system.

The server may transmit an indication of the file and the UID/GID to the distributed file system, which may compare the UID/GID to a list of authorized identifiers for the file. If the UID/GID is on the list of authorized identifiers, the distributed file system may execute the request accordingly.

Abstract: Example implementations relate to connecting an IoT device to a wireless network using Device Provisioning Protocol (DPP). An authentication server receives a DPP network access authorization request including a connector identifier from an Access Point (AP) in communication with the IoT device. The connector identifier is a hash of the public network access key of the IoT device. If the connector identifier is valid, the authentication server determines a configurable policy from a set of configurable policies that is applicable to the IoT device. The authentication server transmits network permissions defined in the configurable policy to the AP. The IoT device is connected to the wireless network by the AP based on the network permissions.

Abstract: A process for service chain instance pool sizing receives service requests for processing in a 5G network by a service function chain, of the 5G network, providing network function(s) to process the service requests. The method determines an average number of service requests to be processed, and determines a number of service chain instances to exist in a pool of service chain instances, of the service function chain, as a composite of (i) a number of instances to process service requests having arrived and making an initial relay through the service function chain and (ii) a number of instances to process service requests that were re-introduced after having previously arrived. The method additionally indicates the number of service chain instances to exist in the pool to a component responsible for controlling the number of service chain instances in the pool.
