Diabetic retinopathy (Diabetic Retinopathy, DR) is the symptom of diabetes affecting the retina during the onset of diabetes. Aiming at the problem of information loss of lesion areas such as microimages during model downsampling, this paper proposes a module of DenseNet fusion residual structure. This module first connects two consecutive Dense block, then sums the feature information using the residual structure, and processes the feature image information in parallel to prevent the loss of effective feature information. Finally, finally, the residual connects the two convolution blocks containing drop out to suppress the overfitting phenomenon. To solve the problem of the channel weighting of the feature graphs of lesion areas in previous convolution operations, the paper proposes a module of SeNet fusion residue structure. This module first connects SeNet, adds the feature information of global average pooling and global maximum pooling to improve the utilization of effective channel information, and then ensures the integrity of feature graph information through the residual mode of conv1x1. Based on the design of the above two modules, the paper proposes a DR classification method of DenseNet and SeNet fusion residue structures. The model achieves 89.8%precision and 97.0% specificity on the APTOS2019 dataset, 78.8% accuracy and 91.9% specificity on the Messidor-2dataset, which can effectively improve the classification ability of the degree of retinal lesions.

With the launch of a unified national carbon market in China, its synergistic effects on promoting carbon emission reduction in the power industry with renewable energy subsidies are noteworthy. The traditional view is that the total amount of carbon emissions is fixed under the carbon trading policy and the renewable energy subsidy policy under the total amount control will no longer play an additional role in reducing emissions, and would even lead to excessive carbon market quotas, distorting carbon market prices. This paper establishes a general equilibrium analysis framework for national carbon trading and examines the parallel emission reduction effects of renewable energy subsidies in the power industry and the national carbon market and their policy synergy paths. The results show that: ① The national carbon market and renewable energy subsidy policy for the power industry would both bring about CO2 emission reduction in the whole industry. ② The carbon market that only covers the power industry would produce a ‘carbon leakage’ effect, which would lead to an increase in carbon emissions in non-power industries. On this basis, continuing the renewable energy subsidies may alleviate the ‘carbon leakage’ by means of the transfer of production factors among industries or lead to excessive carbon market quotas by ‘greening’ the power production structure. ③ Considering two sources of renewable energy subsidies: the one-time tax on residents (resident income tax) and the renewable energy electricity price surcharge (electricity consumption tax), the emission reduction effect of the former resource is better than that of the latter resource, and the latter may even cause ‘cross-border damage.’ ④ The renewable energy subsidies would lead to a decrease in the carbon market transaction price. The FIT is better than the FIP, and it is necessary to increase the total amount of constraints to effectively restrain the decline of carbon trade prices. As the carbon market expands and improves, renewable energy subsidies can be gradually reduced or even eliminated to avoid their impact on the carbon market price. [ABSTRACT FROM AUTHOR]

BACKGROUND: Although prefabricated flap is an ideal method to repair composite defects, the risk of flap necrosis is still an urgent problem to be solved. Therefore, promoting the revascularization of prefabricated flap can improve its survival rate and reduce complications. OBJECTIVE: To investigate the effect of expanded polytetrafluoroethylene membrane barrier material on vascular regeneration of prefabricated flap in rats. METHODS: Thirty SD rats were randomly divided into three groups with 10 rats in each group: control group, silica gel membrane group and expanded polytetrafluoroethylene group. In the silica gel membrane group and expanded polytetrafluoroethylene group, bilateral back arbitrary flaps (7.5 cm long and 1.5 cm wide) were prefabricated by the barrier delay method. Silica gel membrane and expanded polytetrafluoroethylene membrane were implanted under the flap. In the control group, the flap was prefabricated with non-barrier delay method, and the flap was directly sutured in situ without barrier under the flap. The vascular regeneration was observed after operation. At 14 days after operation, the flap tissue was stained with hematoxylin and eosin. Immunohistochemistry for vascular endothelial growth factor and CD34 was utilized to detect the activity of superoxide dismutase and the level of malondialdehyde. RESULTS AND CONCLUSION: (1) At 2 weeks after operation, the flap was cut again. In the silica gel membrane group, some rats had axial vascular regeneration and one rat had silicone curl. All rats in the expanded polytetrafluoroethylene group had obvious axial vessels. (2) The microvessel density of expanded polytetrafluoroethylene group was significantly higher than that of control group and silica gel membrane group (P < 0.05). The number of CD34 positive vessels in expanded polytetrafluoroethylene group was significantly higher than that in the control and silica gel membrane groups (P < 0.05). The integral absorbance of vascular endothelial growth factor protein in the expanded polytetrafluoroethylene group was significantly higher than that in the control and silica gel membrane groups (P < 0.05). (3) The activity of superoxide dismutase in the expanded polytetrafluoroethylene group was higher than that in the silica gel membrane group and control group (P < 0.05), and the level of malondialdehyde was lower than that in silica gel membrane group and control group (P < 0.05). (4) Using expanded polytetrafluoroethylene membrane as barrier delay material can promote the angiogenesis of prefabricated flap in rats, reduce oxidative stress, and improve the survival rate of the flap.

In order to study the damage and deterioration of concrete under sulfate attack at early age, the porosity of concrete samples with different corrosion ages in clear water environment and sulfate environment was measured by the mercury intrusion porosimetry (MIP) test. Then the distribution of sulfate ions in the concrete was measured by the spectrophotometric method. The ultrasonic velocity of concrete with different corrosion ages was measured. The results showed that the porosity of concrete in clear water group firstly decreased and then gradually tended to a fixed value, and the porosity of concrete in sodium sulfate solution firstly decreased and then increased. The variation law of the ultrasonic velocity of concrete was negatively correlated with the variation law of porosity. At last, combined with the distribution law of sulfate ion and Fick's second law, a Stratified-Theoretical model of corroded concrete was established. Then the coefficient of concrete compaction rate of corrosion layer was calculated and the results were consistent with the deterioration process of concrete. [ABSTRACT FROM AUTHOR]

Based on the particle spectrum of floating dust, with the analysis of the scattering efficiency factor and scattering coefficient of floating dust particle size by Mie scattering theory; Monte Carlo method was used to simulate and analyze the effect of floating dust particle size and concentration on UV communication in floating dust weather. Finally, an experimental device was built to test and analyze the effects of particle size and concentration on UV communication performance in different floating dust weather, the results of which were then contrasted with the simulation ones. The results show that: 1)the scattering efficiency factor and extinction efficiency factor of floating dust particles show an oscillatory attenuation trend, and the oscillation finally converges near 2.07 and 1.14 with the increase of scale parameters, respectively. 2)When the floating dust concentration is constant, the path loss of UV communication decreases first and then increases with the increase of particle size, and the radius of the minimum is 1.0～1.5 μm. 3)During short distance communication in dusty weather, the path loss decreases with the increase of dust concentration and increases with the increase of communication distance and transceiver elevation.
