Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A user equipment (UE) may receive, from a base station, information indicating that a coverage enhancement mode is supported. The UE may determine whether to enter the coverage enhancement mode based on a downlink signal synchronization block (DL SSB). In response to determining to enter the coverage enhancement mode, the UE may transmit a reserved preamble to the base station to initiate random access for the coverage enhancement mode.

Abstract: Methods to optimize solvent use in solvent-dominated processes for recovery of hydrocarbons. Methods include injecting a solvent composition into a reservoir at a pressure above a liquid/vapor phase change of the solvent composition; injecting a chaser into the reservoir at a pressure above the liquid/vapor phase change of the solvent composition; allowing the solvent composition to mix with hydrocarbons in the reservoir and at least partially dissolve into the hydrocarbons to produce a solvent/hydrocarbon mixture; reducing the pressure in the reservoir below the liquid/vapor phase change pressure of the solvent composition thereby flowing at least a fraction of the solvent/hydrocarbon mixture from the reservoir; and repeating these steps as required.

Abstract: A method and apparatus for pushing information. A specific implementation of the method includes: parsing page content browsed by a user to extract a keyword of the page content and determine a theme corresponding to the keyword; determining a preset keyword matching the keyword in a preset keyword collection; determining an associated keyword associated with the determined preset keyword based on a pre-established associated relationship of the preset keyword; and pushing information corresponding to the theme and/or the associated keyword to the user. This implementation implements targeted information push.

Abstract: A variable discretization method for general multiphase flow simulation in a producing hydrocarbon reservoir. For subsurface regions for which a regular or Voronoi computational mesh is suitable, a finite difference/finite volume method (“FDM”) is used to discretize numerical solution of the differential equations governing fluid flow (101). For subsurface regions with more complex geometries, a finite element method (“FEM”) is used. The invention combines FDM and FEM in a single computational framework (102). Mathematical coupling at interfaces between different discretization regions is accomplished by decomposing individual phase velocity into an averaged component and a correction term.

Abstract: A current steering folding circuit is provided. The current steering folding circuit includes a load and at least one current source for drawing a current from the load. The current steering folding circuit also includes a first output signal terminal for providing a first output signal, and a second output signal terminal for providing a second output signal. A current steering section is also provided. The current steering section steers the current between the first output signal terminal and the second output signal terminal based on an input signal. The first output signal is substantially equal to the second output signal for N values of the input signal. Advantageously, the number of current sources does not exceed N.
