Abstract: A mask module includes a framework, a first strip plate fixed on the framework and extending along a first direction, and a first mask. The first mask is located on a side, deviating from the framework, of the first strip plate. The first mask includes at least one preset area, and the preset area includes at least one opening area. The first strip plate is provided with a first concave-convex structure on one side edge along the first direction. At least one convex structure is provided in a middle of the first concave-convex structure along the first direction. In a direction perpendicular to a surface of the first mask, the first concave-convex structure and the convex structure cover at least a part of area of the at least one opening of the preset area. The convex structure and the first strip plate are integrally formed.

Abstract: Systems and methods for robotic teleoperation are provided. The system receives motion input and gaze data of a human operator performing a robotic teleoperation task, and a plurality of features are extracted from the received data. A recurrent neural network determines latent actions from the extracted features and generates temporally associated action inferences. A model determines inferred intention from a sequenced pair of action inferences, an intention hierarchy, and a probabilistic uncertainty function. A teleoperated robotic element performs a task associated with the inferred intention without a corresponding control signal from the human operator. The recurrent neural network is trained using extracted features and contrastive learning. The intention hierarchy is generated from action inferences. The probabilistic uncertainty function is generated using Bayesian hierarchical modeling. The system and method improves robotic teleoperation by estimating the intention of the human operator.

Abstract: The present invention provides the use of SE-DR (an HLA-DR molecule containing the shared epitope) affinity peptides in the preparation of a medicament for the treatment of rheumatic diseases in the rheumatoid patients being tuberculosis-positive and/or complicated with hepatitis B. The invention solves the problem of limited choice of drugs for the patients with the rheumatic disease. The invention also provides a pharmaceutical composition comprising an SE-DR affinity peptide and a non-antigen-specific anti-rheumatic drug, and its use in the preparation of a medication for the treatment of various types of rheumatic diseases. The pharmaceutical composition can quickly delay the procession of the rheumatic disease, and can achieve sustained remission after the drug tapering or discontinuation, so as to completely control the rheumatic diseases.

Abstract: In some embodiments, a computing system extrapolates aggregated interaction data associated with users of an online platform by applying a mixed granularity model to generate extrapolated interaction data for each user in the users. The aggregated interaction data includes a total number of occurrences of a target action performed by the users with respect to the online platform. The extrapolated data includes a series of actions leading to the target action for each user. The computing system identifies an impact of each action in the series of actions for each user on leading to the target action based, at least in part, upon the extrapolating a series of actions associated with the user. User interfaces presented on the online platform can be modified based on at least the identified impacts to improve customization of the user interfaces to the users or enhance an experience of the users.
