Abstract: A cleaning robot system, including a cleaning robot with a cleaning module connected to the cleaning robot. The cleaning module includes a main body, connectable with a cleaning medium to wipe a working surface. The main body is provided with a connection region for connection of the cleaning medium and a demounting region for demounting of the cleaning medium, and no interconnection action occurs between the demounting region and the cleaning medium. The cleaning module of the cleaning robot effectively fixes the cleaning medium to the main body through the connection region. When the cleaning medium needs to be removed from the main body, the cleaning medium can be more easily and conveniently be demounted from the main body by means of the demounting region because no interconnection action occurs between the demounting region and the cleaning medium.

Abstract: The lesion locating method includes locating a lesion by locating a mark on a body surface; using a camera in locating to assist an ultrasound probe for locating; forming a reference view according to data acquired in real time by the camera, where the reference view has a preset size, and a virtual mark point corresponding to the mark is formed in the reference view; and determining, according to a position of the virtual mark point in in the reference view and an actual positional relationship of the camera and the ultrasound probe, an actual locating trajectory that enables a center line of the ultrasound probe to coincide with the mark. The camera is configured to acquire camera data to form the reference view, and then assists the ultrasound probe for locating with the reference view.

Abstract: A starch biosynthesis method may implement total artificial biosynthesis from simple compounds such as dihydroxyacetone, formaldehyde, formic acid and methanol to starch. By coupling with methods such as chemical reduction of carbon dioxide, even total artificial biosynthesis of starch taking carbon dioxide as a starting raw material can be implemented. The method can utilize carbon dioxide of high concentration and high density and electric energy and hydrogen energy of high energy density, is more suitable for an industrial production mode, and the production cycle is shortened from several months in farming to several days.

Abstract: Described herein are immune cells comprising: a T-cell receptor (TCR) and a chimeric stimulating receptor (CSR) that comprises (i) a ligand-binding module that is capable of binding or interacting with a target ligand; (ii) a transmembrane domain; and (iii) a CD30 costimulatory domain, in which the CSR in the immune cells lacks a functional primary signaling domain.

Abstract: Provided are an uncovering assembly of a household appliance, and a household appliance. A positioning portion cooperates with a positioning structure on a shell of the household appliance in the uncovering assembly, a cover is prevented from being loosened relative to the shell, in this way visual fool proofing may be achieved. A lock catch switches from an unfastening position to a fastening position after the positioning portion cooperates with the positioning structure. The lock catch, after entering the fastening position, is in mutual restriction with a fastening structure in a vertical direction.
