Abstract: A packet transmission method and apparatus, a device, and a computer-readable storage medium. An example is used in which the method is applied to a first communication device serving as an intermediate node in a transmission process. The method includes: the first communication device first obtains a first packet; selects, based on a network quality condition corresponding to the first packet, a first physical interface from at least two physical interfaces corresponding to a logical interface to send the first packet. A network quality parameter of the first physical interface corresponds to the network quality condition.

Abstract: This application provides a method for forwarding a service packet, a method for sending an SR policy, a device, and a system, and belongs to the field of network technologies. In the solution provided in this application, a network device may forward, according to a first candidate path in an SR policy through a sub-interface corresponding to a first network slice, a service packet, and the first candidate path and a first identifier of a first network slice corresponding to the first candidate path are encapsulated in the service packet.

Abstract: The present disclosure relates to the field of biotechnologies. Specifically disclosed are an interferon signaling pathway-related gene panel and an in vitro diagnostic product thereof, and the use of the same in assessing the recurrence risk of breast cancer and/or providing guidance for breast cancer treatment with interferon.

Abstract: Disclosed is a gene panel which can evaluate lung adenocarcinoma molecular subtype and survival risk, and an application of a reagent, which detects the gene expression level of the gene panel, in preparing a product. The product is used for determining lung adenocarcinoma molecular subtype and evaluating lung adenocarcinoma patient survival risk. The product comprises a Next-Generation Sequencing (NGS) detection reagent kit, a fluorescence quantitative PCR detection reagent kit, a gene chip and a protein microarray. Also disclosed is a method which uses the detection reagent kits to evaluate lung adenocarcinoma molecular subtype and survival risk.

Abstract: This disclosure provides a biodegradable antimicrobial material based on polylactic acid oligomer represented by formula 1 as an active ingredient. The disclosure also provides a process for preparing the polylactic acid oligomer and an antimicrobial product prepared therefrom.

Abstract: The lithography apparatus includes at least two exposure devices and one substrate device. The substrate device includes a substrate stage and a substrate supported by the substrate stage. The at least two exposure devices are disposed in symmetry to each other above the substrate with respect to a direction for scanning exposure and configured to simultaneously create two exposure fields onto the substrate to expose the portions of the substrate within the exposure fields.

Abstract: Provided is a bio-based material having an antibacterial effect, comprising a polymer represented by a formula (1) or a mixture of the polymer represented by the formula (1) and polyethylene glycol as an antibacterial active ingredient.
