Abstract: The disclosure relates to a method, apparatus, readable medium, and electronic device for live stream interaction. The method includes: in accordance with displaying of a first control at a first target position of a live stream interface, obtaining a first duration during which a user watches the live stream interface; in accordance with a determination that the first duration is greater than or equal to a first predetermined duration threshold, switching the first control to a second control, and displaying the second control at a second target position of the live stream interface; and in response to a first operation command performed by the user on the second control, allocating a virtual resource to the user. In this way, interaction modes of a live stream room are enriched, and an activity level of the live stream room can be improved.

Abstract: A semiconductor device includes a type IV semiconductor base substrate, a first type III-V semiconductor layer formed on a first surface of the base substrate, and a second type III-V semiconductor layer with a different bandgap as the first type III-V being formed on the first type III-V semiconductor layer. The semiconductor device further includes first and second electrically conductive device terminals each being formed on the second type III-V semiconductor layer and each being in ohmic contact with the two-dimensional charge carrier gas. The base substrate includes a dielectric layer formed directly on a lower region of type IV semiconductor material, and a highly-doped layer of type IV semiconductor material formed directly on the dielectric layer.

The base substrate includes a first highly doped island that is disposed directly beneath the second device terminal and extends to the first surface of the base substrate. The first highly-doped island is laterally disposed between portions of semiconductor material having a lower net doping concentration than the first highly-doped island.

Abstract: A drain pump for an appliance includes a single, self-starting, single-phase synchronous motor and a pump chamber having an inlet and first and second outlets. The first outlet is a drain outlet and the second outlet is a recirculation outlet. An impeller is disposed within the pump chamber and is selectively and bi-directionally driven by the single-phase synchronous motor. Rotation of the impeller in a first direction directs fluid from the inlet toward the drain outlet and away from the recirculation outlet. Rotation of the impeller in the second direction directs the fluid from the inlet toward the recirculation outlet and away from the drain outlet.
