Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

Abstract: A display device includes a blocking dam. The blocking dam includes an insulation layer group. A groove is provided at one side of the insulation layer group away from the substrate. After the liquid organic encapsulation material flows from the display area to the highest point of the blocking dam, the excess liquid organic encapsulation material may directly fall into the groove, avoiding the excess liquid organic encapsulation material from flowing across the blocking dam to the outside of the encapsulation area, causing that the orthographic projection of the edge of the organic encapsulation layer, away from the display area, on the substrate is located within the orthographic projection of the blocking dam on the substrate. The display panel includes only one blocking dam, and the width of the area, where the blocking dam is provided, of the non-display area decreases, thereby reducing the width of the entire non-display area.

Abstract: Light transport simulation algorithms or techniques may be used to generate a sample for a subsurface scattering of light, then a target function may be used to improve the sample. The target function may correspond to an amount of energy transported to the surface from within the object. The sample may be resampled using the sample and the target function to update a reservoir of samples. A resampled sample may be selected and used as a lighting sample for the subsurface scattering. Rather than using the resampled sample, it may be used with the target function to again update the reservoir and select another resampled sample from the updated reservoir. This may be performed for any number of iterations to determine the lighting sample for the frame. A backside lighting cache may be used in the ray tracing to determine lighting at the backside of the object.
