Abstract: An integrated base station antenna comprises a passive antenna that includes a front radome, a matching dielectric layer and a rear radome; and an active antenna mounted on the back of the passive antenna. A distance between the rear radome of the passive antenna and the matching dielectric layer is a first distance, and the distance between the active antenna and the rear radome of the passive antenna is a second distance, where the first distance is selected as 0.25+n/2 times the equivalent wavelength, where n is a positive integer, and the second distance is selected as 0.25+N/2 times the equivalent wavelength, where N is a natural number.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for heuristic-based variable rate shading for mobile games. A CPU that includes a GPU driver may obtain draw call information for a first frame of a plurality of frames. The first frame may be shaded based on a default shading rate (e.g., full shading rate). The draw call information may be associated with per shader frame states of the first frame. The CPU may estimate/detect one or more heavy draws for one or more subsequent frames of the plurality of frames based on the per shader states. The CPU may indicate, on a per draw basis, a reduced shading rate (e.g., half-shading rate) to a GPU that generates the one or more subsequent frames of the plurality of frames, when the plurality of frames is estimated to include the one or more heavy draws.

Abstract: A membrane electrode with ultra-low oxygen mass transfer resistance includes an anode catalyst layer, a proton exchange membrane (PEM), and a cathode catalyst layer. A catalyst in the cathode catalyst layer is negatively charged, and the cathode catalyst layer is further doped with a negatively charged carbon carrier. A carbon carrier of the cathode catalyst layer in the membrane electrode is negatively charged, thereby optimizing the distribution of ionomers to achieve the purpose of reducing an oxygen mass transfer resistance in the cathode catalyst layer. In addition, an appropriate amount of the negatively charged carbon carrier is doped to increase a local oxygen concentration near active sites. In conclusion, the two methods of modifying with a negative charge and doping a negatively charged carbon carrier are used to optimize the local mass transfer resistance in an electrode and thus improve the cell performance.
