Abstract

A wave radar image inversion method based on a convolutional neural network, and the application thereof, which relate to the field of sea condition monitoring. A convolutional neural network autoencoder is used, and a training set generated by means of a simulation tool is input into the convolutional neural network autoencoder for supervised training, wherein an X-band radar image of an inversion region is an input of the training set, and a corresponding sea surface wave height map is an output of the training set, thereby obtaining a mapping relationship model therebetween. The convolutional neural network autoencoder comprises an encoder, fully connected layers and a decoder, wherein the encoder comprises five convolutional layers and five maximum pooling layers, the convolutional layers and the maximum pooling layers being alternately connected, the fully connected layers are two symmetric layers, and the decoder comprises five deconvolutional layers. Using a convolutional neural network deep learning algorithm achieves a better effect in restoring nonlinear components. Using an autoencoder technique can directly restore an X-band radar wave image to a real-time sea surface wave height map with a relatively small error, and can more comprehensively display sea condition information.

A master end and a slave end each obtain, by means of heterodyne frequency beating, a millimeter-wave signal from an optical frequency locked to an optical reference consisting of a super-stable laser and an optical atomic clock; the master end and the slave end each send the millimeter-wave signal to the opposite end by means of a spatial link; the master end and the slave end each measure the time difference between a local millimeter-wave signal and the millimeter-wave signal that is received from the opposite end; the slave end can obtain the clock difference between the master end and the slave end by means of a bidirectional comparison principle, thereby implementing bidirectional time-frequency comparison; moreover, the slave end adjusts an optical reference frequency and a phase, such that time-frequency synchronization between the master end and the slave end can be realized. The present invention effectively alleviates the problems of inadequate precision in traditional microwave-based time-frequency comparison methods and relatively low continuous operation rates in traditional optical-carrier-based time-frequency comparison; and has the advantages of a low noise floor, simple structure and high reliability.

Abstract

A method for visible light-mediated chemical modification of a polypeptide or protein based on cysteine includes the following steps: allowing a cysteine residue on a cysteine-containing oligopeptide, polypeptide, or protein to undergo a reaction with an activating reagent to generate a free radical precursor in situ; and subjecting the free radical precursor to desulfurization under photocatalytic condition, and allowing the generated free radical intermediate to undergo an addition reaction with an olefin or an alkyne, such that sulfhydryl removal and carbon-carbon bond construction are achieved to produce a chemical modification product of the polypeptide and protein. The method cleverly avoids the influence on the chiral center, and thus the chirality of the amino acid residue can be retained. The method is conducive to well avoiding the occurrence of side reactions, and thus the efficiency of the entire conversion is very high.

Abstract

The present application relates to the technical field of medicine, and provides a use of PTPRT as a biomarker and a target for predicting the efficacy of immune checkpoint therapy in lung cancer. Further provided is a use of the expression quantity of PTPRT in the prediction or evaluation of the efficacy of immune checkpoint therapy in cancer. Experiments show that the low expression of PTPRT, as a marker for predicting the efficacy of immune checkpoint therapy in lung cancer, can accurately predict progression-free survival (PFS) of lung cancer patients. Inhibition of PTPRT can increase the proportion of tumor-infiltrating CD8+T cells and synergize with immune checkpoint therapy to enhance the anti-tumor effect of an immune checkpoint inhibitor.

Abstract

A flexible DC converter comprises a MMC and a DCPFC embedded within the flexible DC converter. The flexible DC converter features modularity and a flexible number of ports, enabling bidirectional control of DC power flow of two or more lines, addressing the issue of insufficient degrees of freedom in DC power flow control in meshed DC systems. The DCPFC is directly embedded in the flexible DC converter, allowing for energy balance without the need for external power sources and high-voltage isolation devices, with a wide range of power flow regulation. The control method can manage both internal and external energy balance of the device. Additionally, a main circuit parameter designing method can serve as a basis for selecting circuit components for the device. A fault protection strategy and an active fault current suppression method can enhance the reliability of the device under complex extreme conditions.
