Abstract: Disclosed are a display substrate. The display substrate includes a drive backplane; a first electrode layer disposed on a side of the drive backplane; a pixel definition layer disposed on a side, distal to the drive backplane, of the first electrode layer; an organic light-emitting layer disposed on a side, distal to the drive backplane, of the pixel definition layer, wherein the organic light-emitting layer comprises: a plurality of organic material layers stacked in a direction perpendicular to and away from the drive backplane, and a portion of the organic material layer disposed inside the partition groove is separated from a portion of the organic material layer disposed outside the partition groove; and a second electrode layer disposed on a side, distal to the drive backplane, of the organic light-emitting layer.

Abstract: A method, apparatus, and server for generating a user score based on social networking information is provided. In the disclosed method, by processing circuitry of an information processing apparatus, default annotation information of a plurality of sampled users, an ith user score and an ith relative user score for each of the sampled users are obtained. A user score model is trained according to the ith user score of the respective sampled user, the ith relative user score of the respective sampled user, and the default annotation information of the respective sampled user. An (i+1)th user score of the respective sampled user is subsequently calculated and a trained user score model, for each of the sampled users, is obtained when the (i+1)th user score for the respective sampled user satisfies a training termination condition, The method provides a solution to evaluate the user score for a use when personal information of the user is missing or incorrect.

Abstract: A burner comprises a stove core, a fire cover, and a stove plate and stove end. A plurality of stove core fire outlet hole lugs are arranged on the stove core, stove core fire outlet holes are arranged on each of the stove core fire outlet hole lugs, and a stove core air inlet channel is arranged between adjacent stove core fire outlet hole lugs. A plurality of fire cover fire outlet hole lugs are arranged on the fire cover, fire cover fire outlet holes are arranged on each of the fire cover fire outlet hole lugs, a fire cover air inlet channel is arranged between adjacent fire cover fire outlet hole lugs, and the direction of fire outlet position of the stove core fire outlet hole faces the channel opening of the corresponding fire cover air inlet channel. With the flames of the stove core and the flames of the fire cover being crossed by the alternating arrangement of the fire outlet holes, the air contact area is enlarged such that the heat efficiency is improved.
