Abstract: An electrode assembly, a preparation method therefor, a battery, and an electrical apparatus are disclosed. The electrode assembly includes an electrode plate comprising a current collector, an active layer, and a tab. The active layer is disposed on at least one side of the current collector in its thickness direction, and the tab is arranged on one side of the current collector in its height direction. In a direction from the tab side toward the opposite side and from the current collector toward the outward side, the liquid absorption capacity of the active layer gradually decreases. Such gradient structure enables the active layer to exhibit different electrolyte absorption capacities in a specified direction, improving electrolyte wettability. The configuration further reduces electrolyte loss caused by electrode plate expansion or contraction during charge and discharge, thereby enhancing overall wettability of the electrode assembly.

Abstract: Various disclosed embodiments are directed to deriving an albedo output image from an input image based on deriving an inverse shading map. For example, an input image can be a photograph of a human face (i.e., the geometric features) with RGB values representing the color values of the face as well as pixels representing shadows (i.e., the shadow features) underneath the chin of the human face. The inverse shading map may be a black and white pixel value image that contains pixels representing the same human face without the RGB values and the shadows underneath the chin. The inverse shading map thus relies on the geometric space, rather than RGB space. Geometric space, for example, allows embodiments to capture the geometric features of a face, as opposed to those geometric features' RGB or shadow details.

Abstract: Aspects and features of the present disclosure provide a direct ray tracing operator with a low memory footprint for surfaces enriched with displacement maps. A graphics editing application can be used to manipulate displayed representations of a 3D object that include surfaces with displacement textures. The application creates an independent map of a displaced surface. The application ray-traces bounding volumes on the fly and uses the intersection of a query ray with a bounding volume to produce rendering information for a displaced surface. The rendering information can be used to generate displaced surfaces for various base surfaces without significant re-computation so that updated images can be rendered quickly, in real time or near real time.

Abstract: The present disclosure relates to a visible light-catalyzed translucent concrete, and a preparation method and use thereof. The preparation method includes: extracting an iron oxide from a copper slag, mixing the iron oxide with TiO2 to obtain a photocatalyst, and then mixing the photocatalyst with an additive to obtain a photocatalytic slurry; preparing a concrete slurry using the copper slag after iron extraction as an aggregate; and pouring the photocatalytic slurry, the concrete slurry, and the photocatalytic slurry in sequence into a mold pre-laid with an optical fiber, to obtain the visible light-catalyzed translucent concrete. In the visible light-catalyzed translucent concrete, iron in the copper slag is used as a part of raw materials of the photocatalyst, and the copper slag after iron extraction is used as an aggregate to replace natural sand and gravel. This solves environmental pollutions caused by the copper slag and realizes resource utilization.

Abstract: In implementing per-asset denoising for real-time rendering of neural radiance fields (NeRFs), a processing device receives a three-dimensional (3D) representation of a scene as a NeRF. The processing device generates an intermediate rendering of the scene using the NeRF. The intermediate rendering is denoised using a machine-learning model to generate a final rendering. The machine-learning model is trained on another rendering of this scene, which was rendered using a non-real-time, high-quality rendering scheme. In other words, the machine-learning model is optimized for each scene and provides a lightweight denoising network to provide real-time NeRF rendering while maintaining the high-quality visuals of non-real-time rendering schemes. The final rendering is then presented via a display device.

The disclosed system utilizes a light encoder neural network to generate a representation embedding of lighting in a digital image. Additionally, the disclosed system determines points of the three-dimensional object visible within a camera view. The disclosed system generates a self-occlusion map for the digital three-dimensional object by determining whether fixed sets of rays uniformly sampled from the points intersects with the digital three-dimensional object. The disclosed system utilizes a generator neural network to determine a shading map for the digital three-dimensional object based on the representation embedding of lighting in the digital image and the self-occlusion map.

Abstract: Techniques for generation of compressed representations for appearance of fiber-based digital assets are described that support computationally efficient and high fidelity rendering of digital assets that include fiber primitives under a variety of lighting conditions and view directions. A processing device, for instance, receives a digital asset that includes fiber primitives to be included in a three-dimensional digital scene. The processing device generates a compressed representation of the digital asset that maintains a geometry of the digital asset and includes a precomputed light transport. The processing device then inserts the compressed representation into the digital scene, such as at a location relative to one or more light sources. The processing device applies one or more lighting effects to the compressed representation based on the precomputed light transport and the location relative to the one or more light sources.
