Abstract: The present application provides immune cells (such as T cells) comprising a chimeric antibody-T cell receptor (TCR) construct (caTCR) and a chimeric signaling receptor (CSR) construct. The caTCR comprises an antigen-binding module that specifically binds to a target antigen and a T cell receptor module (TCRM) capable of recruiting at least one TCR-associated signaling molecule, and the CSR comprises a ligand-binding domain that specifically binds to a target ligand and a co-stimulatory signaling domain capable of providing a stimulatory signal to the immune cell. Also provided are methods of making and using these cells.

Abstract: Data processing techniques comprise, in response to determining that a storage unit storing first data blocks is damaged, determining storage units associated with the storage unit, and obtaining second data blocks from the storage units, where the second data blocks and the first data blocks are generated by applying to data an error correction code in a first format. The method further comprises recovering the first data blocks based on the second data blocks. In addition, the method comprises generating error correction blocks by applying an error correction code in a second format to the recovered first data blocks, where the second format is different from the first format. The above techniques can reduce input/output operations and shortens the recovery time of data blocks, and further can reduce the risk of data loss even in an extremely bad situation.

Abstract: Embodiments of the present disclosure provide a method, an electronic device and a computer-readable medium for managing metadata. The method disclosed herein comprises: obtaining a check marker from a remote device; determining whether the check marker indicates that user data and metadata have been backed up in the remote device, the user data and the metadata being generated by an operation executed by a user on an object; and in response to the check marker indicating that the user data and the metadata have been backed up in the remote device, marking the metadata as removable metadata. In this way, the embodiments of the present disclosure can improve garbage collection efficiency of a storage system and execution efficiency of a metadata integration task.

Abstract: The present disclosure relates to a method, apparatus and computer program product for managing a storage system. According to implementations of the present disclosure, there is provided a method for managing a storage system. In the method, an object vector is created based on multiple objects stored in the storage system, here an object element in the object vector is associated with at least one object among the multiple objects. Multiple chunks included in the storage system are divided into multiple groups. For a group among the multiple groups, a chunk vector is created based on each chunk in the group, here a chunk element in the chunk vector is associated with a chunk in the group. A mapping matrix is created for managing the storage system based on the object vector and the chunk vector. Moreover, there is provided an apparatus and computer program product for managing a storage system.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device associated with a social networking application. While running a social networking application, the first computing device detects a near-field wireless communication signal broadcasted by a second computing device associated with a service provider account registered with the social networking application.

Abstract: Techniques are described for implementing automated control systems to control operations of specified physical target systems, such as with one or more batteries used to store and provide electrical power. Characteristics of each battery's state may be used to perform automated control of DC power from the battery, such as in a real-time manner and to optimize long-term operation of the battery. In some situations, multiple batteries are controlled by using multiple control systems each associated with one of the batteries, and with overall control being coordinated in a distributed manner using interactions between the multiple control systems. A system that includes one or more batteries to be controlled may further include additional components in some situations, such as one or more electrical sources and/or one or more electrical loads, with one non-exclusive example of a type of such system being one or more home electrical power systems.

Abstract: Embodiments of this application provide a near-field wireless communication service processing method performed at a first computing device. While running a social networking application, the first computing device listens to a near-field wireless communication signal broadcasted by a second computing device. After detecting the near-field wireless communication signal broadcasted by the second computing device, first computing device processes the near-field wireless communication signal to obtain identification information associated with the second computing device. The first computing device sends the identification information associated with the second computing device to a remote server supporting the social networking application and obtains a preset service page corresponding to the identification information associated with the second computing device from the server, and displays the preset service page within the social networking application on the first computing device.

Abstract: The present invention discloses a method and system for implementing short message encryption. Both the Mobile Station (MS) and the Mobile Switching Center (MSC) are configured with encryption-decryption modules (1), which can encrypt and decrypt the short message by using the Cipher Key (CK) as the encryption-decryption factor. The CK is variable with the Random value (RAND). The CK is not shared between the receiving end and the sending end in the whole process, so that the encrypted short message has a high confidentiality. In addition, the security of the whole transmission environment can be realized by the selectable configuration.
