Abstract: The present invention provides a graphene oxide-tetraethyl orthosilicate (TEOS)/silane composite gel material, and a preparation method and use thereof, and belongs to the technical field of building surface coating. The graphene oxide-TEOS/silane composite gel material provided by the present invention includes the following components: 5-45 parts by weight of graphene oxide dispersion, 30-90 parts by weight of TEOS, 30-80 parts by weight of silane, 1-5 parts by weight of emulsifier, and 1-5 parts by weight of dispersant; the graphene oxide dispersion has a concentration of 0.5-5%. The graphene oxide-TEOS/silane composite gel material provided by the invention can form a hydrophobic anticorrosive coating after coating the surface of a cement-based material, and has excellent water resistance and corrosion resistance.

Abstract: A method for regression and time series forecasting includes obtaining a set of hierarchical time series, each time series in the set of hierarchical time series including a plurality of time series data values. The method includes determining, using the set of hierarchical time series, a basis regularization of the set of hierarchical time series and an embedding regularization of the set of hierarchical time series. The method also includes training a model using the set of hierarchical time series and a loss function based on the basis regularization and the embedding regularization. The method includes forecasting, using the trained model and one of the time series in the set of hierarchical time series, an expected time series data value in the one of the time series.

Abstract: The present disclosure provides a pea peptide with auxiliary hypoglycemic function, and preparation method and application thereof. The pea peptide includes at least peptide segments pEE, pEK and pER in its composition; and based on a mass of the pea peptide, a content of the peptide segment pEE is ?100.00 mg/100 g, a content of the peptide segment pEK is ?80.00 mg/100 g and a content of the peptide segment pER is ?90.00 mg/100 g. The pea peptide has a significant efficacy in an aspect of reducing blood glucose.

Abstract: Devices, computer-readable media, and methods for making a cache admission decision regarding a video chunk are described. For instance, a processing system including at least one processor may obtain a request for a first chunk of a first video, determine that the first chunk is not stored in a cache, and apply, in response to the determining that the first chunk is not stored in the cache, a classifier to predict whether the first chunk will be re-requested within a time horizon, where the classifier is trained in accordance with a set of features associated with a plurality of chunks of a plurality of videos. When it is predicted via the classifier that the first chunk will be re-requested within the time horizon, the processing system may store the first chunk in the cache.

Abstract: A device, system and method for content-adaptive resolution-enhancement is provided. A plurality of subframe streams are generated from a video stream, each of the plurality of subframe streams comprising a lower resolution version of the video stream, pixel-shifted from one another. A plurality of output subframe streams are generated from the plurality of subframe streams in a one-to-one relationship by: applying a plurality of video enhancement filters to each of the plurality of subframe streams, each of the plurality of video enhancement filters for enhancing different features of the video stream; and, combining one or more resulting enhanced subframe streams into a respective output subframe stream based on data in one or more regions of the video stream. One or more projectors are controlled to project the plurality of output subframe streams to combine the plurality of output subframe streams into a higher resolution projected video stream.
