Abstract: The present technology relates to systems and methods for evaluating a user's sleep data. More particularly, the present technology contemplates a computer-implemented system or method of evaluating a quality of sleep for a user based on sleep data, such as by determining a set of quality metrics for the user's sleep based on the sleep data using a set of probabilistic models.

Abstract: An electrolyte for electrochemical decontamination and a preparation method and application thereof. The electrolyte is an aqueous solution including the following solutes: phosphoric acid, oxalic acid, citric acid, tartaric acid, hydrogen peroxide and glacial acetic acid. The electrolyte has a good decontamination effect and allows for fast decontamination and is obtained by reasonably combining different types of solutes and controlling the levels of the solutes and resulting secondary waste solution and residues are easy to treat. The electrolyte is suitable for overall or local electrochemical decontamination of radioactively contaminated stainless steel scrap.
