摘要： An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for Reference Signal Time Difference (RSTD)-based 5G-NR positioning. The processing circuitry is to determine a first PRS BW associated with a first PRS received from a first gNB associated with a first cell. A second PRS BW is determined, which is associated with a second PRS received from a second gNB of a second cell. An RSTD report resolution is determined based on the first PRS BW and the second PRS BW. A receive (Rx) timing difference between the first cell and the second cell is measured based on reception times of the first PRS and the second PRS. The measured Rx timing difference is mapped into an RSTD report for transmission to the first gNB, based on the RSTD report resolution.

摘要： A volume-scalable, high-brightness, electrically driven visible light source comprises a three-dimensional photonic crystal (3DPC) comprising one or more direct bandgap semiconductors. The improved light emission performance of the invention is achieved based on the enhancement of radiative emission of light emitters placed inside a 3DPC due to the strong modification of the photonic density-of-states engendered by the 3DPC.

摘要： Exemplary embodiments provide semiconductor devices with a high-quality semiconductor material on a lattice mismatched substrate and methods for their manufacturing using low temperature growth techniques followed by an insulator-capped annealing process. The semiconductor material can have high-quality with a sufficiently low threading dislocation (TD) density, and can be effectively used for integrated circuit applications such as an integration of optically-active materials (e.g., Group III-V materials) with silicon circuitry. In an exemplary embodiment, the high-quality semiconductor material can include one or more ultra-thin high-quality semiconductor epitaxial layers/films/materials having a desired thickness on the lattice mismatched substrate. Each ultra-thin high-quality semiconductor epitaxial layer can be formed by capping a low-temperature grown initial ultra-thin semiconductor material, annealing the capped initial ultra-thin semiconductor material, and removing the capping layer.

摘要： A method for displaying a formation model while drilling a wellbore in the formation includes operating a well logging instrument at a measurement point in the formation along a wellbore while the wellbore is being drilled. Measurement data regarding the formation are obtained from the well logging instrument. An actual orientation of a geological structure is determined from the measurement data. A trajectory of the wellbore is displayed in three dimensions as it is being drilled through the formation. While drilling the wellbore, the geological structure is displayed along the trajectory of the wellbore according to the determined actual orientation of the geological structure. The actual orientation reflects an azimuth angle of planes corresponding to the geological structure. The trajectory of the wellbore is changed in response to displaying the determined actual orientation of the geological structure relative to the trajectory.

摘要： Various technologies for removing shoulder-bed effects from measurements of an earth formation made in a wellbore. In one implementation, a methodology for removing the shoulder-bed effects includes receiving the measurements and constructing a layered model of the earth formation. Each layer has a set of parameters corresponding to one or more types of the received measurements ascribed to each layer such that the set of parameters define a parameter space for the layered model. The methodology may further include dividing the parameter space into subspaces based on relationships among the parameters, selecting from the subspaces one or more starting points, minimizing a cost function using the one or more starting points to generate one or more candidate solutions having the shoulder-bed effects removed and selecting a final solution from the one or more candidate solutions.

摘要： A method of forming a virtually defect free lattice mismatched nanoheteroepitaxial layer is disclosed. The method includes forming an interface layer on a portion of a substrate. A plurality of seed pads are then formed by self-directed touchdown by exposing the interface layer to a material comprising a semiconductor material. The plurality of seed pads, having an average width of about 1 nm to 10 nm, are interspersed within the interface layer and contact the substrate. An epitaxial layer is then formed by lateral growth of the seed pads over the interface layer.

摘要： A method is described for characterizing a subsurface formation with a logging instrument disposed in a borehole penetrating the formation. The logging instrument is equipped with at least a transmitter system and a receiver system. The method entails positioning the logging instrument within the borehole so that the transmitter system and receiver system are disposed in the vicinity of a formation boundary of interest and measuring the azimuthal orientation of the logging instrument. Electromagnetic energy is transmitted into the formation using the transmitter system and signals associated with the transmitted electromagnetic energy are measured using the receiver system. The method further entails determining the relative azimuth of the formation boundary, composing a symmetrized directional measurement using the measured signals and the determined relative boundary azimuth, and determining the relative dip of the formation boundary using the composed directional measurement.
