Abstract: A method for displaying augmented reality, a device, a storage medium, and a terminal are provided. A field of view and resolution of an augmented reality display device and a viewing angle of a user are acquired. A standard text width ratio of virtual information to be displayed is acquired. Then, a text display font size corresponding to the virtual information is determined according to the resolution, the field of view, the viewing angle, and the standard text width ratio. Further, a text display line height and a text display blank height corresponding to the virtual information can be determined based on the text display font size. Finally, a content of the virtual information is formatted and displayed according to the text display font size, the text display line height, and the text display blank height.

Abstract: Disclosed are compositions, methods, and kits for clearing tissue that preserve cellular morphology, reporter fluorescence, and epitope labeling which allow for quantitative phenotypic analysis of intact organs. The compositions include, for example, a compound of formula R1—C(X)—NR2R3, wherein R1 is alkyl, haloalkyl, hydroxyalkyl, amino, or alkylamino, X is O or S, and R2 and R3 are independently H, alkyl, or hydroxyalkyl, a salt thereof, or a combination thereof, and at least one non-ionic density gradient medium. Also disclosed are methods for clearing tissue comprising positioning a tissue in a tissue clearing composition and allowing a tissue clearing composition to permeate the tissue. Further disclosed are methods for visualizing tissue characteristics which involve fixing a tissue, staining the tissue, positioning the tissue in the tissue clearing composition and allowing the tissue clearing composition to permeate the tissue, and imaging the tissue utilizing a microscope or tissue scanning device.
