Abstract: Embodiments of the present disclosure provide a display substrate and a display panel. The display substrate has a light-transmissive region and a light-shielding region, and the light-shielding region includes a main support region and a secondary support region. The display substrate includes a substrate, an alignment layer on the substrate, and a convex structure on the alignment layer. The convex structure is on a side of the alignment layer distal to the substrate and at least in the main support region, and a distance from a surface of the convex structure distal to the substrate to the substrate is greater than a distance from a surface of the alignment layer distal to the substrate to the substrate.

Abstract: The present disclosure provides a method and a system for quickly determining transient stability of a half-wavelength transmission system. The method includes: obtaining power and a power angle of a feeding-end generator of a half-wavelength transmission system; and determining transient power angle stability and a power angle instability mode of the half-wavelength transmission system by using a constructed index system, where two power angle instability modes, that is, an instability mode 1 and an instability mode 2, are specifically constructed for the half-wavelength transmission system based on an equal area method. Based on the equal area method, the present disclosure constructs two instability modes specific to the half-wavelength transmission system, so as to accurately describe transient power angle characteristics of the half-wavelength transmission system under a severe fault, and characteristics of the two instability modes are significantly different from those of an AC transmission mode.

Abstract: The features relate to artificial intelligence directed detection of user behavior based on complex analysis of user event data including language modeling to generate distributed representations of user behavior. Further features are described for reducing the amount of data needed to represent relationships between events such as transaction events received from card readers or point of sale systems. Machine learning features for dynamically determining an optimal set of attributes to use as the language model as well as for comparing current event data to historical event data are also included.

Abstract: A live streaming sharing system includes a first live streaming sharing apparatus, a server, and a second live streaming sharing apparatus. The server receives first live streaming data transmitted by a first live streaming sharing apparatus; receives a remote live streaming instruction transmitted by a second live streaming sharing apparatus; and transmits the first live streaming data to the second live streaming sharing apparatus according to the remote live streaming instruction. The second live streaming sharing apparatus is configured to generate and present first virtual reality (VR) live streaming data accordingly. The present disclosure achieves an effect of sharing VR content among a plurality of users, thus improving the interactivity and practicability of the solution.
