Abstract: A method and a device for nidus recognition in a neuroimage, an electronic apparatus, and a storage medium are provided. A collection of neuroimages to be recognized, including a first structural image, a first nidus image, and a first metabolic image, is determined, and then image preprocessing is performed on the collection of neuroimages to acquire a collection of object images including a second structural image, a second nidus image, and a second metabolic image. The collection of object images is input into a trained three-dimensional convolutional neural network to acquire a position of a nidus of the target object, and then the position of the nidus is labeled on the first structural image based on the position of the nidus of the target object to acquire and display an image of the position of the nidus.

Abstract: The present invention relates to a pharmaceutical composition comprising a ?-lactam compound of formula (I), or a stereoisomer, a solvate or a pharmaceutically acceptable salt or ester thereof, and a lactamase inhibitor or an efflux pump inhibitor, and the use thereof for inhibiting microorganisms, particularly bacteria, especially Gram-negative bacteria, wherein each symbol in formula (I) is as defined in the description.

Abstract: This application provides a speaker module and an electronic device, and the electronic device includes a speaker module. The speaker module includes a shell, a vibration assembly, and a damping film, where the vibration assembly is mounted in an inner portion of the shell, the vibration assembly divides the inner portion of the shell into a front cavity and a back cavity, the shell is provided with a through hole, the through hole is communicated with the front cavity and the back cavity, and the damping film is mounted in the inner portion of the shell and covers the through hole, where an elastic modulus of the damping film is less than an elastic modulus of the vibration assembly.

Abstract: The present invention relates to a compound as shown in general formula (I) below (in formula (I), each of R1 and R2 independently represents a hydrogen atom or a C1-10 linear or branched alkyl optionally having a substituent, or the two together form a cycloalkyl with 3 to 8 ring carbon atoms; each of R3 and R4 independently represents a hydrogen atom or a C1-10 linear or branched alkyl optionally having a substituent or a C6-12 aryl optionally having a substituent, or the two together form a cycloalky with 3 to 8 ring carbon atoms; X represents C or N; and Y represents a linear or branched alkenyl or alkynyl with 2 to 6 carbon atoms and optionally having a substituent, or carboxyl). The compound has good antibacterial properties against bacteria, especially gram-negative bacteria, has low drug resistance, and has good prospects for the effective treatment of various conditions.
