Abstract: The present invention provides a linker for preparing antibody-drug conjugates and antibody-drug conjugates prepared by the linker, as well as use of the antibody-drug conjugates in a medicament for treating tumor. The linker is capable of coupling simultaneously with the thiol group or amino group on the antibody or functional fragment of the antibody, especially it is capable of coupling with 2, 3 or 4 thiol groups on the antibody or functional fragment of the antibody. A coupled product is uniform and structurally stable.

Abstract: A method for installing a maximum power point tracking (MPPT) controller is provided. The method includes acquiring an occlusion area proportion of a photovoltaic string in a photovoltaic system, optimizing the occlusion area proportion to generate a target occlusion area proportion, determining a target position from the photovoltaic string according to the target occlusion area proportion, and installing the MPPT controller at the target position.

Abstract: The present disclosure relates to a method for analyzing a geological body with the help of physical and chemical properties thereof, and in particular, to a method for identifying an exudative sandstone uranium deposit. With the method for identifying an exudative sandstone uranium deposit according to the embodiments of the present disclosure, an exudative sandstone uranium deposit formed by an exudation metallogenesis may be systematically identified, so as to guide prediction and prospecting evaluation of a uranium deposit in red variegated sandstone formations of a sedimentary basin, avoid ore dislocation and ore leakage, open up new prospecting positions and spaces, and break through new uranium resources.

Abstract: Managing source code change set commits to decrease time to identify software bugs in versions of a software project is provided. An initial order of relevant commits corresponding to the software project is determined in a priority queue based on a weight of each respective commit of the relevant commits. The initial order of the relevant commits is adjusted in the priority queue based on a build distance between the relevant commits of affected source files. A particular commit having a highest priority ranking is selected in the priority queue for build and test. The build and the test of the particular commit having the highest priority ranking in the priority queue is executed.

Abstract: Provided are techniques for using relocatable debugging information entries to save compile time when there are changes to source code. While compiling source code, for an unchanged function, a copy is made of a relocatable debugging information entries table and of a relocation information table. In addition, for a changed function, a new relocatable debugging information entries table and a new relocation information table are generated. The copy of the relocatable debugging information entries table and the new relocatable debugging information entries table are merged. The copy of the relocation information table and the new relocation information table are merged. The relocatable debugging information entries in the merged relocatable debugging information entries table are resolved according to information in the merged relocation information table to generate relocated Debugging with Attributed Record Formats information, which is stored in an object file that corresponds to the source code.

Abstract: A system and machine-implemented method of generating panoramic photographs and videos. Panoramic image data in a YUV data format is received in a YUV data format by an integrated circuit. A format of the panoramic image data is detected by the integrated circuit. The format includes resolution, pixel clock, line frequency information, and field frequency information. The panoramic image data is output, by the integrated circuit, to a memory unit. The panoramic image data is processed by the integrated circuit. The integrated circuit retrieves the panoramic image data from the memory unit. The processed panoramic image data is output, by the integrated circuit, to a processing unit. The processing includes at least one of projecting, stitching or distortion correcting.

Abstract: Provided in the present invention is an asparaginic acid kinase, and the 340th amino acid residue in the position of the amino acid sequence of the asparaginic acid kinase corresponding to the amino acid sequence shown in SEQ ID NO: 2 is a non-aspartic acid. The asparaginic acid of the present invention can efficiently relieve the feedback inhibition of L-lysine, and can be effectively used for the production of L-lysine. Also provided in the present invention are host cells comprising genes coding the asparaginic acid kinase and a method for producing L-lysine using the host cells or the asparaginic acid kinase. The asparaginic acid kinase of the present invention or the host cells comprising the asparaginic acid kinase of the present invention is also used to produce L-threonine, L-methionine, L-isoleucine or L-valine. Also provided in the present invention is a method of producing L-aspartyl-4-yl phosphoric acid using the asparaginic acid kinase or the host cells.

Abstract: A charged particle detector with high detection efficiency is presented in this patent. This charged particle detector contains a grid electrode used for attracting charged particles, a convertor with the shape of particle entrance area smaller than the particle exit area, which is used for converging charged particles and converting ions into electrons in the ion detection mode, an electron detection unit used for detecting secondary electrons and amplifying the signal detected, and a metal shielding. This optimized detector has a simple construction, is easy to assemble and has a low manufacturing cost.
