Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: Disclosed are a control method and apparatus for safety boot of a chip, an electronic device and a storage medium. The method includes: determining, at a preset stage of a chip boot process, first mirror data to be checked at the preset stage and first check code corresponding to the first mirror data, from a decryption result obtained by a hardware security module; determining second check code based on the first mirror data; comparing the second check code with the first check code to obtain a comparison result; determining an integrity check result of the first mirror data based on the comparison result; and executing, based on the integrity check result, a safety boot program corresponding to the first mirror data at the preset stage.

Abstract: A formulation includes a plurality of polymers including a hydrophobic polymer backbone (for example, formed via radical polymerization), a first plurality of pendant groups attached to the hydrophobic polymer backbone and including at least one cationic group, and a second plurality of pendant groups attached to the hydrophobic polymer backbone and including at least one hydrophilic polymer, a first therapeutic compound, and a second therapeutic compound, wherein the second therapeutic compound is different from the first therapeutic compound and includes a nucleic acid.

Abstract: A method of quantifying the effect of peripheral optical errors on patient locomotion includes projecting a pattern on the floor that includes a discrete shapes and empty spaces between the discrete shapes. The method also includes tracking a position of the participant along the pattern as the participant traverses the pattern, and determining foot placement accuracy, utilizing a optical motion capture system and a computer, as the participant walked through the pattern by determining a total area of overlap between the participant's feet and the empty spaces of the pattern. In another embodiment, the method includes arranging obstacles in front of a participant, intermittently displaying a character in front of the participant, determining participant's accuracy in identifying or counting the characters, and determining the participant's step length and foot clearance as the participant steps over the obstacles to quantify the effect of the peripheral optical errors on the participant's locomotion.
