Abstract: Provided are a preparation method for a CTL cell and an application thereof. The preparation method comprises the following steps of: inducing a CTL cell by using a tumor antigen PAP-GM-CSF sensitized DC cell; and knocking out a PD-1 gene of the CTL cell to obtain a PD-1 knock-out CTL cell. The CTL cell obtained by the preparation method can be used for preparing drugs for treatment of prostate cancer, especially for treating PAP-positive prostate cancer. The CTL cell does not cause CTL cell failure and anergy due to the tumor-expressed PD-L1 after being transfused into the body, thereby producing efficient specific cytotoxic effect on a tumor cell and improving the curative effect and reducing the side effect.

Abstract: A container kernel upgrade based on a programmable container kernel, includes, in response to receiving a container kernel upgrade request, freezing an application container in which a to-be-upgraded first container kernel is located. Current container status data of an application container including first container kernel status data and application status data is stored. The application container is restarted by using a second container kernel used for upgrading a container kernel, where restarted container status data of the restarted application container includes second container kernel status data corresponding to the second container kernel when the application container is restarted. Using the stored current container status data, a corresponding data field is updated in a data structure of the restarted container status data.

Abstract: Disclosed is an unmanned aerial vehicle (UAV)-aided over-the-air computing system based on full-duplex relay and a trajectory and power optimization method thereof. The UAV-aided over-the-air computing system adopts the UAV as a full-duplex relay for data fusing and forwarding. The method of the application aims at minimizing an average mean square error of over-the-air computing, and solves an optimization problem under constraints of sensor transmitting power, information transmission rate, UAV trajectory and denoising factor. For an overall joint optimization problem, each optimization variable is determined one by one by an alternative optimization method according to the high coupling of optimization variables.

Abstract: New benzodiazepine compounds, and a preparation method therefor and the use thereof are provided. Short-acting benzodiazepine derivatives have the characteristics of a fast onset, short acting time, deep strength, being quickly metabolized, fast wake-up, etc. In anesthesia experiments on mice and rats, short-acting benzodiazepine derivatives have a comparable onset time to remazolam, but have a significantly shortened acting time and wake-up time. Moreover, some of the compounds have a significantly enhanced depth of action. Thus, the compounds have the characteristics of a faster onset, shorter acting time, greater strength of action, being metabolized faster, faster wake-up, etc. In long-term infusion anesthesia experiments on rats, compared with remazolam, the short-acting benzodiazepine derivatives have a significantly shortened wake-up time and recovery time, and have the characteristics of faster wake-up, a faster recovery, etc.

Abstract: A method for generating a brush effect picture includes: determining a pattern extraction area on a display interface in response to an area selection operation on the display interface of a display; obtaining a first brush effect picture based on the pattern extraction area, where a pattern of the first brush effect picture is a pattern corresponding to the pattern extraction area on the display interface; and obtaining a second brush effect picture based on the first brush effect picture, where the pattern of the first brush effect picture is the same as a pattern of the second brush effect picture, and definition of the second brush effect picture is greater than definition of the first brush effect picture.

Abstract: The invention provides a method for load-balanced traffic grooming in an IP over Quasi-CWDM network, including the steps of: inputting a network topology, a set of service traffics between nodes in node pairs and a null route, and when selecting one of the node pairs from the set of service traffics and establishing a traffic request between the nodes in the node pair, deleting the virtual link for which the corresponding light path has no sufficient remnant capacity in an IP layer of the network; finding the virtual link route having the lowest hop count in the IP layer, and determining whether each virtual link on the route can satisfy the service request by means of traffic grooming; and if yes, adopting the traffic grooming strategy to satisfy the service request; and if not, adopting the wave plane based strategy to establish a light path to satisfy the service request.

Abstract: The invention belongs to the technical field of building materials, mainly relates to a high-strength carbon fiber composite bar with resin ribs on the surface, and a preparation method thereof. The invention comprises a carbon fiber and an epoxy resin matrix, wherein continuous spiral epoxy resin ribs are arranged on the surface of the bar, the thickness of the resin ribs is within 0.2 mm-0.4 mm, the width of the resin ribs is within 5 mm-7 mm, and the pitch of the resin rib is within 2 mm-4 mm. According to the present invention, during the forming process, the nylon belt winding of the present application does not squeeze the carbon fiber bundle, and due to tension of the carbon fiber bundle, the carbon fiber bundle remains straight along the lengthwise direction of the bar. Therefore, the bar manufactured by the method of the present invention has the characteristics of high strength and high modulus.

Abstract: A magnetic tunnel junction (MTJ) includes a first iridium layer, a first tungsten layer, a first ferromagnetic layer, a tunneling barrier layer, a second ferromagnetic layer, a second tungsten layer and a second iridium layer in sequence, wherein the two ferromagnetic layers are respectively a reference layer with a fixed magnetization direction and a free layer with a reversible magnetization direction. When the magnetization direction of the reference layer is parallel to the magnetization direction of the free layer, the MTJ is in a low-resistance state to store a binary digit “0”; when the magnetization direction of the reference layer is anti-parallel to the magnetization direction of the free layer, the MTJ is in a high-resistance state to store a binary digit “1”. The present invention can enhance tunneling magnetoresistance effect by using iridium layer, improve read reliability and reduce writing power consumption of the MTJ.
