TL;DR: In this article , a quantum two-stage criticality with spin-valley isospins arising in chiral-stacked twisted double bilayer graphene (cTDBG) was observed.

TL;DR: In this article, a method and a device for identifying a target object in an image is described, which includes the following steps: extracting feature data from an image and converting the extracted feature data into a unified expression; automatically clustering the features of the image according to the feature data after unified expression and a historical clustering result; categorizing a known classification included in the automatic clustering results as a corresponding known classification so as to identify a known target object.

TL;DR: In this paper, a feature selection method based on federation training is proposed, which comprises the following steps: federating two aligned training samples by using XGboost algorithm to construct a gradient lifting tree model, and feature ranking being performed based on the score of each feature and the ranking result being output for feature selection.

TL;DR: This work proposes the consistency regularization for Grand by leveraging the distributional consistency of unlabeled nodes in multiple augmentations, improving the generalization capacity of the model.
