针对多模态医学图像融合过程中多尺度特征和纹理细节信息丢失的问题,提出一种基于生成对抗网络和多尺度空间注意力机制的图像融合算法。首先,生成器采用自编码器结构,分别利用编码器和解码器对输入图像进行特征提取、融合和重建,生成融合图像;其次,整个对抗网络框架采用双鉴别器结构,使得生成器生成的融合图像同时保留多个模态图像的显著特征;最后,构建一种多尺度空间注意力机制作为编码器进行特征提取的基本模块,利用多尺度结构充分捕获并保留源图像的多尺度特征,并且引入空间注意力机制更好地保留源图像的结构和细节信息。哈佛大学全脑图谱数据库上的实验结果表明:所提算法生成的融合图像不仅纹理细节更为丰富,有助于人类视觉观察,而且在3种不同类型的医学图像融合任务上平均梯度、峰值信噪比、互信息、视觉信息保真度等客观评价指标的平均值分别达到0.3023、20.7207、1.4414、0.6498,与其他先进的算法相比具有一定的优势。

A bistatic space debris observation system using a radio telescope as the receiving part is introduced. The detection capability of the system at different working frequencies is analyzed based on real instruments. The detection range of targets with a fixed radar cross section and the detection ability of small space debris at a fixed range are discussed. The simulations of this particular observation system at different transmitting powers are also implemented and the detection capability is discussed. The simulated results approximately match the actual experiments. The analysis in this paper provides a theoretical basis for developing a space debris observation system that can be built in China.

Actual textile wastewater and synthesized wastewater containing various textile dyes were photocatalytic degraded by the UVH2O2Fs-TiO2 process in an aimular-flow photocatalytic reactor. In this process, a photon kinetic-measure was adopted to obtain constant rates of dyes decomposition. It was theorized that, by illumination at different UV frequencies, the electrons within the semiconductor were excited from the valence band to the conduction band, yielding the formation of electron-hole pairs which are the pre-requisites for photocatalysis. CPT （critical photonic time） exposure required to cause 90% of vibrations between the double and single bonds along the molecular chain of the dyes to be oxidized, was taken to measure the photocatalytic activities. The CPTs varied with the frequencies of the UV spectral areas. The derivatization of CPT from the first-order kinetic law was presented.

An indoor chamber facility is described for investigation of atmospheric aerosol chemistry. Two sets of α-pinene ozonolysis experiments were conducted in the presence of dry ammonium sulfate seed particle: ozone limited experiments and α-pinene limited experiments. The concentration of gas phase and particle phase species was monitored continuously by on-line instruments and recorded automatically by data sampling system. The evolution of size distribution was measured by a scanning mobility particle sizer ...

Slow-release polymeric fertilizer containing multiple nutrients was synthesized through condensation polymerization from raw materials of homemade low-molecular urea-formaldehyde and the compounds of potassium dihydrogen phosphate and phosphoric acid. Adjustment of the proportion of raw materials makes the ingredients of the fertilizer are N:P_2O_5:K_2O =1:0.75:0.13, which satisfy the nutritional requirement for maize growth. Field-experiment results prove that the yield of maize increases by 16.56% when using the polymeric fertilizer special for maize alone, by 56.51% when applying the polymeric fertilizer special for maize plus farmyard manure, and by 49.11% when applying the SV fertilizer special for maize plus manure.
