Abstract: An ultrasonic-assisted permeation and homogenization molding device and method for frozen printing liquid drops are provided. The device includes an ultrasonic generator, a transducer and an amplitude-change pole. The ultrasonic generator generates 20 KHz low-frequency ultrasonic waves, and a flange plate is arranged on a pitch surface of the amplitude-change pole and connected with an outer cavity wall of the low-temperature molding chamber by threads. According to the ultrasonic-assisted permeation and homogenization molding method for frozen printing liquid drops, pre-paved molding sand particles are homogenized and distributed under ultrasonic vibration by adjusting the frequency of the ultrasonic generator in a sand paving process. When a pure water binder is sprayed, liquid drops are sprayed to the surface of premixed molding sand, and then permeate to the bottom of pre-cooled molding sand under the assistance of low-frequency ultrasonic waves to freeze and solidify.

Abstract: Embodiments of the present application provide a GRPC-based chip test method, a GRPC-based chip test apparatus, and a storage medium. The GRPC-based chip test method comprises: determining a number of to-be-tested chips that actually need to be tested among to-be-tested chips, and issuing a corresponding number of remote instrument call requests according to the number of to-be-tested chips that actually need to be tested; acquiring each of the remote instrument call requests based on a GRPC protocol; and sorting all the remote instrument call requests to form a request execution sequence table, and controlling the test instrument to sequentially test the to-be-tested chips that actually need to be tested according to the request execution sequence table.

Abstract: Intercom systems and methods for image data transmission are provided. The intercom system may include a first intercom including a first image acquisition device, one or more second image acquisition devices, and a second intercom. During an intercom with the second intercom, the first intercom may receive a request for target image data captured by one or more target image acquisition devices of the first image acquisition device and the one or more second image acquisition devices from the second intercom. The one or more target image acquisition devices may include at least one target second image acquisition device of the one or more second image acquisition devices. In response to the request, the first intercom may obtain the target image data from the one or more target image acquisition devices. The first intercom may also send a signal encoding the target image data to the second intercom for display.

Abstract: The present invention relates to an application of an isoquinoline compound in tumor treatment. Specifically, the present invention provides a use of a compound of formula I, or an optical isomer or a racemate thereof, or a solvate thereof, or a pharmaceutically acceptable salt thereof used for the preparation of a composition or formulation for the prevention and/or treatment of a tumor. The compound of the present invention has significant and exceptional therapeutic effects on tumors with low or no expression of an NNMT gene, high expression of a DNA methylase, high expression of UHRF1, high methylation levels at an NNMT gene nucleotide site, and/or high methylation levels at a DNA CpG site in an NNMT gene region.

Abstract: The present invention relates to a marker for determining anti-cancer effects of a mitochondrial oxidative phosphorylation pathway inhibitor. Specifically, the present invention relates to use of the mitochondrial oxidative phosphorylation pathway inhibitor for preparing a composition or a formulation for preventing and/or treating tumors. The present invention has found that the mitochondrial oxidative phosphorylation pathway inhibitor has significantly excellent treatment effects on tumors having mitochondrial oxidative phosphorylation pathway up-regulation, low or no expression of an NNMT gene, high expression of a DNA methylase, high expression of UHRF1, a high methylation level of a nucleotide site of an NNMT gene and/or a high methylation level of a DNA CpG site of an NNMT gene region.

Abstract: Provided are scutellariae radix compounds and the use thereof for inhibiting the oxidative phosphorylation pathway of mitochondria. Specifically provided is the use of a compound of formula I, or an optical isomer thereof, or a racemate thereof, or a solvate thereof, or a pharmaceutically acceptable salt thereof in the preparation of a composition or a preparation. The composition or the preparation is used for one or more uses selected from the group consisting of: (a) inhibiting the oxidative phosphorylation pathway of mitochondria; (b) preventing and/or treating diseases associated with the oxidative phosphorylation pathway of mitochondria; and (c) preventing and/or treating cancers.

Abstract: Disclosed are a method and an apparatus for acquiring inventory data, a terminal device and a computer-readable storage medium. The method comprises: receiving a request for inventory data sent by a terminal device, where electronic tag data of the target item being carried in the request for inventory data; according to the inventory data request, searching among inventory record data pre-stored in a blockchain network for target inventory data corresponding to the electronic tag data, where the target inventory data being corresponding to the target item; and sending the target inventory data to the terminal device.

Abstract: Systems and methods for obtaining access to a session with a remote cloud service server. The methods comprising: receiving, by a first client computing device, a user unique identifier from a mobile device located in proximity to the first client computing device; and performing facial recognition operations by the first client computing device subsequent to the reception of the user unique identifier. The facial recognition operations comprise: capturing an image of the mobile device's user; and analyzing the image to obtain a user name associated with the facial features represented therein. A determination is made as to whether the user name matches the user unique identifier. If so, a first session with the remote cloud service server is automatically launched.
