Abstract: The present application relates to a vincamine derivative, a preparation method therefor, and use thereof, and belongs to the technical field of preparation of vincamine derivatives. The vincamine derivative has the following advantages: (i) Modification of the tail chain increases the lipid solubility of vincamine compounds without affecting the cerebral blood flow regulation of vincamine itself, thereby helping the carried drug penetrate the blood-brain barrier, exert a brain-protective effect, and improve cerebral microcirculatory disorders. (ii) The tertiary amine group in the parent nucleus structure of the vincamine derivative is ionizable under acidic conditions, which enables efficient delivery and lysosomal escape of nucleic acid drugs through charge adsorption, thereby improving intracellular transport. (iii) The vincamine derivative inherits various pharmacological activities inherent to vincamine, and has high safety.

Abstract: A device receives a computation graph and transforms the computation graph into a dataflow graph comprising recursive subgraphs. Each recursive subgraph comprises a tuple of another recursive subgraph and an operator node, or an empty graph. The device determines a number of partitioning recursions based on a number of parallel computing devices. For each partitioning recursion, the device determines costs corresponding to operator nodes, determines a processing order of the recursive subgraphs, and processes the recursive subgraphs. To process a recursive subgraph, the device selects a partitioning axis for tensors associated with an operator node of the recursive subgraph. The device outputs a partitioning scheme comprising partitioning axes for each tensor associated with the operator nodes.

Abstract: In certain scenarios, resource preemption may occur. A user equipment (UE) is configured to monitor for a preemption indication based on a specific downlink configuration. This configuration provides information about whether preemption is identified within a data space in terms of resource blocks. The UE receives data transmissions from a base station at different times and a preemption indication in a group common physical downlink control channel. Based on this preemption indication and the downlink configuration, the UE determines if a portion of the shared downlink resources occupied by the initial data is preempted from use. If the resources are not preempted, the UE proceeds to decode the initial data.

According to the drainage demand, the existing intersection elevation is changed or the intersection elevation that meets the drainage requirement is designed and implemented in new construction so that the intersection drainage is distributed according to the desired proportion; the water flowing to the water accumulation position is transferred to reduce the waterlogging degree. Through the analysis of the depth of water accumulation in the whole road network, the method of water flow distribution at the intersection is used to make the precipitation flow evenly distributed in the whole road network. The method can be used for solving serious water accumulation of a certain road section, the balanced drainage of the whole road network, the technical transformation of existing intersections, and for the planned and designed roads. The method can effectively eliminate and prevent urban waterlogging.
