Abstract: The present disclosure is directed to a composition for the sustained-release delivery of an active agent to a target cell of an individual. The compositions disclosed herein comprise of at least one porous particle; at least one polymer; and at least one active agent. In an embodiment, the porous particle comprises a plurality of microscale reservoirs. In an exemplary embodiment, the at least one active agent is covalently linked to the at least one polymer to form a polymer-active agent conjugate, and the polymer-active agent conjugate is contained in the plurality of microscale reservoirs of the porous particle. In some embodiments, the active agent is released with zero-order or near zero-order kinetics following administration of the composition. The present disclosure is also directed to a method of treating a tumor by administering to an individual the composition described supra.

Abstract: A method for synchronizing data among heterogeneous data sources is disclosed. The method may comprise obtaining a synchronization task and a corresponding operation classification, determining one or more Reader plugins and Writer plugins based on the corresponding operation classification, segmenting the synchronization task based on the one or more Reader plugins and Writer plugins to generate a Task queue, and using a corresponding number of the Reader plugins and the Writer plugins based on the Task queue to implement the synchronization task. The one or more Reader plugins may be configured to read data from a source and to send to the one or more Writer plugins, and the one or more Writer plugins may be configured to write the data to a destination.

Abstract: A method of multithreading extraction of data from a database is provided. The method comprises: acquiring a set of primary key character strings, the primary key character strings being uniquely associated with the data to be extracted from the database; extracting, from the primary key character strings, a first character string and a second character string; generating a first integer and a second integer based on: a preset base number, positions of characters included in the first and second character strings; determining a node segment based on the first and second integers, the node segment being associated with a node segment integer; converting the node segment integer to a node segment character; and generating an extraction statement associated with a thread for the node segment character converted from the node segment integer. The extraction statement can then be transmitted to a database when the thread is executed.

Abstract: Embodiments of the present application provide a data snapshot acquisition method and system. The method includes: acquiring a data change record on the basis of a redo log file started from a position and recorded in a source end; loading the data change record to a destination end; and acquiring, in the destination end, a first data snapshot corresponding to a preset time according to the data change record when the preset time arrives. The present application can acquire a data snapshot of a specified time precisely.

Abstract: Embodiments of the present invention provide an apparatus and a method for recording a reboot reason of equipment. Besides a first watchdog provided for triggering a global reset of the equipment, the apparatus provided by the present invention further includes a second watchdog. The second watchdog is used to trigger a logic chip to record a value representing the reboot reason of power-down in a storage array after the equipment is powered on. Thus, reboot reason of the equipment could recorded as power-down reboot.
