Abstract: A pixel arrangement structure are provided, which includes a plurality of repeating units. Each of the plurality of repeating units includes two first sub-pixels, one second sub-pixel, and one third sub-pixel. Each of the first sub-pixel, the second sub-pixel and the third sub-pixel includes a pixel defining layer, the pixel defining layer includes a pixel defining layer opening to define an effective light emitting region of each sub-pixel; a plurality of first sub-pixels are arranged along the second direction to form a plurality of first sub-pixel groups, orthographic projections of pixel defining layer openings of the first sub-pixels in adjacent ones of the plurality of first sub-pixel groups on a straight line parallel to the second direction do not overlap each other.

Abstract: An apparatus for adsorbing a mask includes an adsorbing member and a controller connected to the adsorbing member. The adsorbing member is configured to adsorb the mask during evaporation and is capable of simultaneously producing different or a same adsorption force to different regions of the mask. The controller is configured to control the adsorbing member to start adsorption from at least one initial adsorption region of the mask, and then control the adsorbing member to gradually expand an adsorption range from the at least one initial adsorption region until the mask is entirely attached to a base substrate.

Abstract: A framework for data change notification includes a notification queue storing event notifications. Client applications can request event information regarding various data change events. For example, a client application can subscribe, via one or more APIs, to receive event information. The framework allows for session specific event notification mechanisms as well as durable event notification mechanisms that can be preserved across client sessions as well as server restarts. Innovative aspects of this invention include guaranteed delivery of event notifications, APIs to allow applications get summary of past events on the subscribed objects, automatic garbage collection/cleanup of notifications when a client session terminates.

Abstract: An improved error-diffusion image processing system and the method thereof adopt the block reading mechanism to replace the row reading mechanism employed in the conventional error-diffusion image processing. This can greatly reduce the memory space required for image processing and increase the operational efficiency. The problem of gaps existing in the block reading mechanism is solved by adding a required error sum (BEsum) in a summed pixel range according to specific position conditions of each block.

Abstract: A competitive immunoassay to measure Lp(a) levels semiquantitatively and identify individuals with elevated plasma Lp(a) protein levels (greater than 7 mg/dl) who have an increase risk for coronary artery disease. The assay is useful for monitoring the effectiveness of Lp(a)-lowering drugs. The assay provides a quick, reliable, easy to use and inexpensive method to measure plasma Lp(a) level with serum, plasma or whole blood.
