Supplemental material, Supplementary material, for Anticolon Cancer Potential of (2Z)-2-[(4′-Hydroxyphenyl) Methylene]-6-Methoxy-7-Prenyl-3(2H)-Benzofurane, a New Aurone From Psoralea corylifolia by Ai-Hua Liu, Li-Hua Liu and Chun-Ying Liu in Natural Product Communications

This paper proposes a new dots homogenization algorithm in digital screening technology. The algorithm provides a solution about homogenizing the maximal surface size of each screen dot as far as possible. The paper also provides an objective quality statistical method to judge the dot homogenization level. The technique has solved moire patterns phenomenon when printing in traditional pattern for the random of dot. Output image is more accurate and more soft since screen dots are more even. It has a low request for equipment and subsequent handling, and entirely meet the needs of traditional printing technology.

The paper introduces about temporal logic of action, it discuss the relation among closure, security, fairness property and liveness property in TLA, action and point out and weak fairness and strong fairness as prerequisites, base on this, it discrible in detail how to establish system model with machine-closed through cases, in the end we gain correct conclusion.

This paper proposes an improved Delaunay triangulation algorithm for digital screening. The algorithm can give a real-time result for its high efficiency. It can give a good solution for Moire patterns phenomenon when printing in traditional pattern. Output image is accurate and soft since gray value distributes uniformly. It has a low request for equipment and subsequent handling, and entirely meet the needs of traditional printing technology.

Channel characteristics of Power line is very important because power line is not designed for data transmission and hostile for communications. This paper presents the testing results of channel properties of power line communications networks in China. According to the nature of distribution networks, office blocks and residential buildings are tested respectively. The testing results show that the main reason influencing the reliable communication of highspeed data of power line is the attenuation of the highfrequency signal, which exhibits more obviously in the branch of power line. For the multi-layer building, it is almost impossible to use the frequency range from 2MHz to 20MHz to realize the reliable communication from distribution transformer to each user, and it must be solved with the aid of such means as the repeater etc. Considering the signal’s attenuation, the lower frequency range is more suitable for the high-speed data communication of power line. So the frequency range of 2MHz-10MHz is suitable for the high-speed data access system of power line. For the question of attenuation, it can be solved with the aid of relaying technique.
