Abstract: A method for stimulating production of hydrocarbons from a sandstone formation includes the steps of injecting a stimulation fluid formed from a hydrofluoric acid generating precursor and an oxidizing agent, an ammonium containing compound, and a nitrite containing compound into the sandstone formation, where one or both of the hydrofluoric acid generating precursor and the oxidizing agent comprise a degradable encapsulation. The method further includes maintaining the stimulation fluid, the ammonium containing compound, and the nitrite containing compound in the sandstone formation to initiate reaction and generate heat and nitrogen gas. Upon generation of heat and degradation of the degradable encapsulation, the hydrofluoric acid generating precursor and the oxidizing agent react to form hydrofluoric acid in-situ to dissolve silica and silicate minerals and stimulate the sandstone formation.

Abstract: A host processing device (“host”) instructs a plurality of data processing (DP) accelerators to configure themselves for secure communications. The host generates an adjacency table of each of the plurality of DP accelerators (“DPAs”). The host is communicatively coupled to the plurality of DPAs via a switch. The host transmits, to the switch, a list of the DPAs and instructs the switch to generate an adjacency table of the DPAs that includes a unique identifier of each DPAs and a communication port of the switch associated with the DPA. The host establishes a session key communication with each DPA and sends the DPA a list of other DPAs that the DPA is to establish a session key with, for secure communications between the DPAs. The DPA establishes a different session key for each pair of the plurality of DPAs.

Abstract: Methods, systems, apparatus, and non-transitory computer readable media are described for using a vehicle as a payment device. Various aspects may include receiving a selection of a stored financial card or financial account at a vehicle head unit. The selected financial card or financial account may be transmitted to a point-of-sale (POS) terminal for making a payment by transmitting a tokenized card number to the POS terminal. The tokenized card number may be transmitted over a very short-range communication link to ensure that the transmission is secure. For example, electronic circuitry may be attached to the exterior of the vehicle, where the electronic circuitry may be within a threshold distance (e.g. one inch, three inches, six inches, one foot, three feet, etc.) of the POS terminal. The tokenized card number may be transmitted from the vehicle head unit to the electronic circuitry and then to the POS terminal.

Abstract: A method of manufacturing a FinFET includes at last the following steps. A semiconductor substrate is patterned to form trenches in the semiconductor substrate and semiconductor fins located between two adjacent trenches of the trenches. Gate stacks is formed over portions of the semiconductor fins. Strained material portions are formed over the semiconductor fins revealed by the gate stacks. First metal contacts are formed over the gate stacks, the first metal contacts electrically connecting the strained material portions. Air gaps are formed in the FinFET at positions between two adjacent gate stacks and between two adjacent strained materials.

Abstract: An electrical submersible pumping system includes thrust bearings and radial bearings fabricated from a micro-grained polycrystalline diamond compact (“USPCD”) material that is ultra-strong; and where the USPCD is produced using a catalyst free process. In examples, all components of the bearings are formed from the ultra-strong USPCD material. Pads are in the bearings that have a contact surface, and the pads selectively tilt about a tilt member in response to variations in an opposing contact surface. The tilt members are attached to or otherwise associated with the pads, and are in contact with a resilient member that improves tilting response of the pads. The resilient members are encased in jackets that cover surfaces of the resilient members not in contact with the tilt members. The jackets are set in channels formed in structure of the bearings.

Abstract: Certain exemplary embodiments relate to entertainment systems and, more particularly, to systems that incorporate digital downloading jukebox features and improved user interfaces. For instance, a smart search may be provided, e.g., where search results vary based on the popularity of songs within the venue, in dependence on songs being promoted, etc. As another example, a tile-based approach to organizing groupings of songs is provided. Groupings may involve self-populating collections of songs that combine centrally-promoted songs, songs in a given genre that are popular across an audiovisual distribution network, and songs that are locally popular and match up with the given genre (e.g., because of shared attributes such as same or similar genre, artist, etc.). Different tile visual presentations also are contemplated, as are different physical jukebox designs. In certain example embodiments, a sealed core unit with the “brains” of the jukebox is insertable into a docking station.

For example, a method includes obtaining a command for calling a remote dedicated processing resource and determining whether the command satisfies an optimization condition based on a type of the command. The method further comprises in response to determining that the command satisfies the optimization condition, ceasing to transmit the command to the remote dedicated processing resource. Accordingly, in the case that the remote dedicated processing resource needs to be called, the number of remote call commands transmitted to the remote dedicated processing resource can be reduced by optimizing the remote call commands, thereby improving the execution efficiency effectively.
