Abstract: A system includes a memory device with dies and a processing device coupled to the memory device. The processing device causes a health scan to be performed on a set of memory units residing within one or more dies and updates, for each read sample taken during the health scan of a unit of memory, an assignment to a voltage offset bin of a plurality of voltage offset bins. The processing device tracks, by a memory data structure, the updated assignments to the plurality of voltage offset bins and generates, based on the memory data structure, an error rate distribution of the memory device. In response to determining that a trigger rate (TR) margin value associated with the error rate distribution does not satisfy a threshold value, the processing device causes a data associated with the unit of memory to be refreshed.

Abstract: Examples provide a system for generating image-based training data using progressive data curation. An anchor image of a selected item and historical receipts including the selected item generated during a dynamic receipt retrieval time period are obtained. Images of the carts including the selected item paired with the receipts are analyzed and cropped to isolate the selected item from each cart image. An embedding model generates embeddings representing the anchor image and the cropped images of the selected item. A similarity of the cropped image embeddings to the anchor image embedding is calculated using a similarity metric. The cropped image embeddings are ranked based on the calculated similarity to the anchor image. The images having the highest rank and greatest similarity to the anchor image are selected for inclusion in training data used to train computer vision models to detect and/or recognize the selected item in images of various objects.

Abstract: Electrocatalytic overall water splitting to generate hydrogen and oxygen is a green and sustainable approach with zero carbon emission, which is important for the future renewable energy landscape. The practical application of this approach is challenging due to the sluggish reaction kinetics of water activation at high current densities, which are hard to overcome. Although high-performance alkaline bifunctional electrocatalysts may be useful, current catalysts lack both activity and durability. One approach is to rationally design bifunctional two-dimensional (2D) heterostructures but obtaining an efficient and durable catalyst has proved difficult. The present disclosure relates generally to an electrocatalyst including a 2D heterostructure (Ru-CMOP), methods of making and using the same. The catalyst of the present disclosure is designed for high activity and good durability at industrial-level high current densities.
