Abstract: The invention belongs to the technical field of material synthesis, and discloses a nitrogen-doped hollow cobaltosic oxide and a preparation method and application thereof. A chemical formula of the nitrogen-doped hollow cobaltosic oxide is Co3O4—COF-T-D@C—N; and the COF-T-D is a covalent organic framework. Due to an open hollow structure, the nitrogen-doped hollow cobaltosic oxide of the invention has a large specific surface area, thus having a large contact area with an electrolyte, which is convenient for lithium ions to transport therein. The open hollow structure also prevents a volume effect from being generated during charging and discharging, and nitrogen is introduced for doping, so that granules can be gradually activated to increase the specific surface area and active sites, a discharge (cycle) stability of the material is improved, and a rate performance of the material is improved.

Abstract: A method for authenticating a passive RFID tag includes acquiring a tag fingerprint of a first tag as a first tag fingerprint, the first tag being the genuine tag; acquiring a tag fingerprint of a second tag as a second tag fingerprint, the second tag being the tag to be authenticated; comparing the first tag fingerprint with the second tag fingerprint: if the first tag fingerprint is consistent with the second tag fingerprint, determining that the second tag is a genuine tag, otherwise determining the second tag is a forged tag. The tag fingerprint is the persistence time enabling the passive RFID tag to operate normally during discharge after fully charging. The beneficial effects include being high in robustness to the change of environment and high in authentication accuracy and capable of being directly deployed on an existing commercial RFID device without modifying hardware of the tag and reader.

Abstract: Technology is disclosed herein for learning motion in video. In an implementation, an artificial neural network extracts features from a video. A correspondence proposal (CP) module performs, for at least some of the features, a search for corresponding features in the video based on a semantic similarity of a given feature to others of the features. The CP module then generates a joint semantic vector for each of the features based at least on the semantic similarity of the given feature to one or more of the corresponding features and a spatiotemporal distance of the given feature to the one or more of the corresponding features. The artificial neural network is able to identify motion in the video using the joint semantic vectors generated for the features extracted from the video.

Abstract: Systems and methods are described for providing social connection between users of first and second electronic eyewear devices. A first object in an environment of the first user is paired with a second object in a remote environment of the second user to create a communication connection between the first object and the second object. When the first object is within a field of view of the first electronic eyewear device, a communication is sent that invokes a preselected augmented reality (AR) object for display to the second user adjacent the second object when the second object is in the field of view of the second user. When the first object is within the field of view of the first electronic eyewear device for a predetermined duration, a communication may be sent that invokes a snapshot of an object or a user-selected AR object for display to the second user.

Abstract: Methods, systems, apparatuses, and computer-readable storage mediums described herein are directed to determining and recommending an optimal compute resource configuration for a cloud-based resource (e.g., a server, a virtual machine, etc.) for migrating a customer to the cloud. The embodiments described herein utilize a statistically robust approach that makes recommendations that are more flexible (elastic) and account for the full distribution of the amount of resource usage. Such an approach is utilized to develop a personalized rank of relevant recommendations to a customer. To determine which compute resource configuration to recommend to the customer, the customer’s usage profile is matched to a set of customers that have already migrated to the cloud. The compute resource configuration that reaches the performance most similar to the performance of the configurations utilized by customers in the matched set is recommended to the user.
