The method includes: collecting a to-be-processed image for a to-be-recognized region through an image collector of a to-be-controlled device, where the to-be-recognized region at least includes a to-be-processed region and an obstacle region; processing the to-be-processed image, and determining information of a partial boundary of a to-be-processed region where the to-be-controlled device is currently located; and controlling the to-be-controlled device to switch between an autonomous movement mode and a remotely controlled movement mode based on the information of the partial boundary to determine a boundary of the to-be-processed region, where the boundary of the to-be-processed region is used for distinguishing the to-be-processed region from the obstacle region. The method can solve the problems of cumbersome operations and low efficiency existing in existing methods for determining a regional boundary.

Abstract: Embodiments herein generally relate to polishing pads and methods of forming polishing pads. A polishing pad includes a plurality of polishing elements. Each polishing element comprises an individual surface that forms a portion of a polishing surface of the polishing pad and one or more sidewalls extending downwardly from the individual surface to define a plurality of channels disposed between the polishing elements. Each of the polishing elements has a plurality of pore-features formed therein. Each of the polishing elements is formed of a pre-polymer composition and a sacrificial material composition. In some cases, a sample of the cured pre-polymer composition has a glass transition temperature (Tg) of about 80° C. or greater. A storage modulus (E?) of the cured pre-polymer composition at a temperature of 80° C. (E?80) can be about 200 MPa or greater.

Abstract: Disclosed are an anti-freezing agent for protecting a biological tissue from being damaged during a freezing treatment and a preparation method therefor. The method for preparing the anti-freezing agent involves mixing ethylene glycol, water and dimethylsulfoxide homogeneously to form a matrix, and then slowly adding sodium polyacrylate. The prepared anti-freezing agent is coated onto biological tissue during a freezing treatment such that damage to the biological tissue is reduced.

Abstract: Data is received downhole from a downhole logging tool to produce received data. The received data is processed to produce processed data. A binary formatting option is selected from a group of binary formatting options, wherein applying the selected binary formatting option to the processed data produces fewer bits than applying any other binary formatting option of the group of binary formatting options to the processed data. The selected binary formatting option is applied to the processed data to produce binary data. The binary data is transmitted uphole. The binary data is received uphole. The received binary data is decompressed to produce uncompressed data. The uncompressed data is processed uphole.
