Abstract: The present application provides a television backlight dimming method, apparatus and device, and a computer-readable storage medium. The television backlight dimming method includes: acquiring a minimum horizontal distance between an LED lamp in a reference region and an LED lamp in a non-reference region; and dimming the brightness of each of the LED lamps in the non-reference region according to the brightness of the LED lamp in the reference region, the minimum horizontal distance and a preset distance rule.

Abstract: An information interaction method and apparatus, an electronic device and a storage medium are provided, the method comprising: displaying a preset first special effect element in a virtual reality space; determining whether a spatial relationship between a target control part controlled by a user and displayed in the virtual reality space and the first special effect element meets a preset condition; and in response to determining that the preset condition is met, displaying a second special effect associated with the first special effect element.

Abstract: The present invention provides scaffolded antigens that have demonstrated improved biochemical and immunogenic properties. The invention also provides engineered SARS-CoV-2 immunogens that contain a modified receptor-binding domain (RBD) sequence. Also provided in the invention are vaccine compositions that contain the scaffolded antigens, including the engineered RBD polypeptides that are fused to the scaffold proteins described herein. The invention also provides methods of using such vaccine compositions in various therapeutic applications, e.g., for preventing or treating SARS-CoV-2 infections.

Abstract: The present application discloses a television backlight dimming method, apparatus and device, and a computer-readable storage medium. The television backlight dimming method includes: acquiring the minimum horizontal interval between an LED lamp in a reference region and an LED lamp in a non-reference region; and dimming the brightness of each LED lamp in the non-reference region on the basis of the brightness of the LED lamp in the reference region, the minimum horizontal interval and a preset interval rule.

Abstract: A method of ecological restoration of water bodies containing excess nutrient includes steps of: (a) taming Daphnia magna to be able to eat blue-green algae as an algae eating plankton with a taming composition fermented from spirulina powder, active yeast, and saccharide, so as to digest blue-green algae in the water bodies, and (b) putting the algae eating plankton in the water body polluted by the blue-green algae, wherein the algae eating plankton eats the blue-green algae, so that an eco-system of the water body containing excess nutrient can be restored. The method according to a preferred embodiment further includes a step of: (c) planting submerged plant in the water, wherein the submerged plant includes submerged forest and submerged turf.
