Abstract: The present disclosure relates to compositions and methods for enhancing infiltration of lymphocytes into tumor tissue, enhancing anti-tumor lymphocyte activities in tumor microenvionment (TME), inhibiting regulatory lymphocyte (e.g., B and T cells) activities in TME, and/or long term benefit of cell therapies. For example, in a method of in vivo cell expansion, the method comprises administering an effective amount of cells comprising an antigen binding molecule to a subject; and administering an effective amount of presenting cells expressing a solid tumor antigen that the binding molecule binds.

Abstract: The present invention discloses a method for protecting a deep learning model based on confidential computing. In this solution, a use process of a deep learning model is divided into two stages: Data preprocessing and inference. At the data preprocessing stage, a data preprocessing model is mainly used to process inference data of an authorized user. The data preprocessing model is a lightweight processing module, which occupies less computing resources, and the data preprocessing model is deployed in a confidential computing environment. At the inference stage, an inference model is used to perform inference on preprocessed data, and the inference model is deployed in a common computing environment. In the entire process, copyright attestation of the deep learning model can be implemented without affecting inference accuracy of the model, and the infringement of the model copyright can be effectively resisted through model forgery, transfer learning, knowledge distillation, and the like.

Abstract: The present disclosure relates to a precision seeding apparatus with recesses on a caterpillar for arranging and distributing seeds against bottoms of seed furrows. The apparatus includes a frame; the frame is provided with a seed box with a seed distribution opening; a caterpillar for transporting seeds capable of being connected with a drive mechanism is arranged in the seed box; a lower part of the caterpillar for transporting seeds corresponds to the position of the seed distribution opening; the caterpillar is provided with at least one column of recesses in a lengthwise direction of the caterpillar; each group of recesses is connected through a seed unloading ditch; the seed unloading ditch is formed into a ring in a lengthwise direction of the caterpillar for transporting seeds; a lower part of the caterpillar for transporting seeds is provided with a comb sheet.

Abstract: The invention discloses a four-dimensional code, an image identification system and an image identification method based on the four-dimensional code, a retrieval system and a retrieval method. All the conceives of the invention are mainly based on the four-dimensional code which includes an identification image and a group of recognition data corresponding to the identification image, wherein the identification image includes a true color image, a two-dimensional code, a color overlaid on the two-dimensional code, and an ID No., and the true color image, the two-dimensional code, the color overlaid on the two-dimensional code and the ID No. have same or corresponding indexes. Data corresponding to the four-dimensional code is stored through a server, and the four-dimensional code or the identification image is scanned during identification or retrieval, so that corresponding data can be retrieved through image identification processing, and returned to a mobile terminal.
