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: Provided are a porous silicone resin and a light-weight flexible flame-retardant composite material, belonging to the technical field of nano-porous materials. The porous silicon resin is prepared from a porous silicon resin precursor solution by means of curing and drying processes. The porous silicone resin precursor solution includes a flame retardant, a surfactant, a siloxane monomer, a catalyst, an auxiliary agent and a solvent. The porous silicone resin precursor solution is obtained by firstly dissolving the flame retardant and the surfactant in the solvent, and then adding the siloxane monomer, the catalyst and the auxiliary agent and mixing them uniformly. The porous silicone resin and the light-weight flexible flame-retardant composite material prepared therefrom have the excellent properties of high porosity, high flame retardancy, high elasticity and high strain.

Abstract: The present disclosure relates to the technical field of composite coating preparation, in particular to a method for plasma-assisted and multi-step continuous preparation of a diffusion layer/amorphous carbon film composite coating and use thereof. In the present disclosure, a high-temperature plasma carburizing/nitriding technology and a low-temperature plasma carbon coating technology are combined by a plasma activation technology with argon ion under gradient cooling, and the surface of a material is activated by multiple bombardment on the surface of the material with high-energy argon ions. In this way, a cluster-like porous and loose structure on a surface of the diffusion layer is removed.

Abstract: Provided are a solidly mounted resonator and a method for preparing a solidly mounted resonator. The solidly mounted resonator includes: a piezoelectric structure, wherein the piezoelectric structure includes: an upper electrode layer, a lower electrode layer and a piezoelectric layer. The lower electrode layer disposed corresponding to the piezoelectric structure, and the lower electrode layer includes: a protruding portion protruding downward corresponding to a lower surface of the lower electrode layer; the piezoelectric layer is disposed on an upper surface of the lower electrode layer; the upper electrode layer is disposed on an upper surface of the piezoelectric layer.

Abstract: A kind of 2-D variable reluctance planar motor comprises: a stator base combined by a plurality of laminated steel bricks; a moving platform consisting of two rows of spaced coil-shoes; traditional sliding supports to hold said platform above said stator base; two electronic rulers for scaling the real position of the platform; traditional supporting means for holding the platform at a distance above the stator base; computer and software for generating motion command signal to PWM generator; PWM current generator for energizing the coils of the moving platform; when a reference data (the final position of the platform) is input into the computer, the computer will give command to the platform and make it moving; once the moving platform is set in motion, the electronic rules continuously detect and transfer the location data of said platform to the computer; the computer continuously compares the data sent by said rules with reference data and gives command to the platform until said two kinds of data are eq

Abstract: The present invention concerns a (4(2?-aminoethyl)amino-1,8-dimethylimididazo(1,2-a)quinoxaline)-4,5-dihydro-1,8-dimethylimidazo(1,2-a)quinoxalin-4-one-2-carboxylic acid (BMS-345541) or an analog thereof for the treatment of melanoma cancer. This compound inhibits NF?B activity and expression, and induces apoptosis in melanoma cancer cells. The present invention also provides a method for assaying for the inhibition of melanoma cancer cell growth.
