Abstract: A photosensitizer molecule increases the retention time thereof in a tumor and the enhancement of the therapy for large-volume tumors. AN-BDP is synthesized by means of introducing anthracene into BODIPY-meso, and due to the strong intermolecular π-π interaction of anthracene, AN-BDP and an amphiphilic block copolymer DSPE-PEG2000 are self-assembled into stable nanoparticles AN-BDP NPs. By means of anthracene, AN-BDP can be excited to a triplet excited state under light irradiation and acts with O2 to generate 1O2. AN-BDP NPs are enriched at the tumor site and retained for about 10 days after tail vein injection. In a mouse tumor model having a conventional volume tumor, AN-BDP NPs can completely inhibit the growth of the tumor by means of one-time tail vein injection and one-time photoirradiation therapy.

Abstract: This invention relates to a method for preparing of a submicro/nano-porous NiO/apatite-type lanthanum silicate anode functional layer. In the method a functional layer nanopowder, ethyl cellulose and terpineol are added into a rotary evaporation bottle containing anhydrous ethanol, and a suspension obtained after mixing is dispersed ultrasonically. The anhydrous ethanol in the suspension is removed by a rotary evaporator. When the suspension becomes a viscous paste, the paste is taken out and ground to complete the preparation of a functional layer paste. The functional layer paste is applied onto an anode substrate by screen printing, and 3 sublayers are screen printed. After dried, the sublayers are heat treated and sintered. The heating rate, the cooling rate and the holding time are controlled in the heating and cooling processes to complete the preparation of the anode functional layer.

Abstract: A steady flow prediction method in a plane cascade based on a generative adversarial network is provided. Firstly, CFD simulation experimental data in the plane cascade are preprocessed, and a test dataset and a training dataset are divided from the simulation experimental data. Then, an Encoding-Forecasting network module, a deep convolutional network module and a generative adversarial network prediction model are constructed successively. Finally, prediction is conducted on test set data: the test set data is preprocessed in the same manner, and data dimensions are adjusted according to input requirements of a saved optimal prediction model; and flow field images in the plane cascade at an inlet attack angle of 10° are obtained through the prediction model. The present invention can effectively avoid the problem of limited measurement range of sensors in an axial flow compressor, and the prediction result is highly consistent with the calculation result of CFD.

Abstract: A design method of a high energy efficiency unmanned aerial vehicle (UAV) green data acquisition system belongs to the technical field of data acquisition and optimization for UAV uplink communication. Firstly, a system optimization objective is constructed; and in a uplink communication network of a single UAV and ground sensors, the UAV receives data periodically. Secondly, according to a constructed optimization problem, the optimization objective is maximization of EE({W},{t},{S}). Finally, an original problem is decomposed into two approximate concave-convex fractional sub-problem based on a block coordinate descent method and a successive convex approximation technique to obtain a suboptimal solution; an overall iterative algorithm is proposed: in each iteration, by solving the sub-problems, wake-up scheduling S, time slot t and UAV trajectory W are alternately optimized. The solution obtained in each iteration is used as the input of next iteration. The present invention can jointly optimize the UAV flight trajectory, the sensor wake-up scheduling and the flight time slot to ensure that the transmission information amount and energy consumption of the sensors satisfy system requirements, while maximizing the energy efficiency of the system.
