The strength and deformation properties of carbon fiber reinforced concrete under different fiber volume loadings under impact loading were studied by using the ɸ100 mm split Hopkinson pressure bar (SHPB) test system. The results show that after the carbon fiber is added, the stress-strain curve of the specimen shows the platform section at the peak stress. The strength and peak strain of the concrete under the impact load increase first and then decrease with the increase of the carbon fiber volume. Trend, when the carbon fiber volume is 0.2%, the impact mechanical properties of concrete are significantly improved.

As an interdisciplinary subject of medicine and artificial intelligence, intelligent diagnosis and treatment has received extensive attention. The standardization of Chinese medicine (CM) diagnosis has been always a bottleneck in the modernization and globalization of CM. Studying the application technology of artificial intelligence in CM and solving the problems is an urgent need for the development of modern CM in the era of artificial intelligence. Taking the pneumonia with dyspnea and cough in CM as an example, this article gives an overview of intelligent medical technology and application development, brings forward the present technical problems faced and the new advances in intelligent technology on CM diagnosis and treatment.

In-plane anisotropic two dimensional (2D) layered materials, such as ReS2, offer one more degree of freedom than isotropic 2D materials to deliver various physical properties. Optical properties of ReS2 flakes are dependent on the layer number (N) from monolayer to multilayer. Here, taking ReS2 flakes with an anisotropic-like (AI) stacking order as an example, we probed their optical properties by optical contrast (OC) measurements. The N-dependent and angular-dependent characteristics of ReS2 flakes were demonstrated respectively by unpolarized and polarized OC curves. The results facilitate further study on out-of-plane and in-plane complex refraction index properties of ReS2 flakes.

Now workflow technique is almost the unique candidate to handle a business process in a software application. But graph based traditional workflow is not enough flexible in software engineer which is well known since it was introduced from manufacture industry in 1980s. Until now how to make workflow more flexible is also an unresolved problem in workflow technique which is a serious bottleneck for its popularization, although many efforts have been done to advance it. Author thinks it is wrong to design a process model based on graph theory, which is just the reason to cause workflow so inflexible. In this paper, author presents new generation process model --- Easy Flow based on task and its semantic, which is easy to understand, design, modify and refactor a business process. Easy Flow model is completely different with workflow model, which is more adept to control a "changing" business process in an enterprise application. Easy Flow will replace workflow to realize real business process management in future applications.
