Abstract: A cabazitaxel weakly-alkaline derivative, preparation, and synthesis thereof, a liposome preparation containing the cabazitaxel weakly-alkaline derivative and application of the cabazitaxel weakly-alkaline derivative in a drug delivery system are provided. Cabazitaxel is connected with a weakly-alkaline intermediate through an ester bond, the ester bond can be broken under the action of esterase in vivo, and an active drug is released. A connecting group is C1-C4 alkyl, C3-C6 naphthenic base or phenyl; [N] is an N-methyl piperazinyl group, a piperidinyl group, a 4-(1-piperidinyl) piperidinyl group, a morpholinyl group, a pyrrolidine group or other tertiary amine structures. The cabazitaxel weakly-alkaline derivative can be prepared into the liposome preparation having high drug loading capacity, high encapsulation efficiency, and good stability.

Abstract: Embodiments of the present disclosure provide a method and apparatus for recognizing speech. An embodiment of the method includes: in response to detecting a speech frame, converting the speech frame into a current text in real time; in response to there being no previously saved historical text, inputting the current text into a semantic parsing model to obtain a parsing result; in response to the parsing result including a valid intention slot, ending a speech endpoint detection to complete the recognition; and outputting an instruction corresponding to the valid intention slot.

Abstract: A test system using a local loop to establish connection to baseboard management control is provided. The test system includes more than one host terminals having at least one network interface card (NIC) and at least one baseboard management controller (BMC) having one NIC. After establishing a connection for test between the host terminals and a remote subscriber, a connection for loop test is established with the BMC through a virtual address, so as to deliver a test instruction to the BMC for testing and to loop back a test result. The test system establishes the connection for loop test through the virtual address so as to perform a remote platform test similar to an inner loop test. Therefore, the test result will not be influenced by a network environment setting, and thus a batch test can be adopted to save the test time.
