    Aphis glycines Matsumura is a rampant insect pest on cultivated soybeans in Jilin Province. Prediction of its occurrence and infesting tendency is an important basis for effective control. Issues related with the application of overwintering egg numbers to predict the occurrence of soybean aphid were studied in this paper. The ratio of winter host numbers to summer host numbers and overwintering egg quantity in different areas of Jilin Province were compared. Based on data about overwintering egg quantities in winter hosts, Rhamnus davaricus, aphid numbers in early and pre-peak infestation stage from 1961 to 1981 in Gongzhuling district and aphid infestation level in Siping district, the relationship between overwintering egg quantity, and aphid number were analyzed. A prediction equation for forecasting aphid quantity and aphid infestation level by the overwintering egg quantity in Gongzhuling district was proposed.Originating text in Chinese.Citation: Cheng, Ruilu, Wang, Suyun, Bao, Xiangzhi, Xu, Enpei, Xie, Weimin.

    This article reports the design and manufacture of colored microcapsules with specific functions and their application in architectural interior wall coating. Utilizing reactive dyes grafted SiO2 shell to encapsulate paraffin through interfacial polymerization and chemical grafting methods, this experiment successfully synthesized paraffin@SiO2 colored microcapsules. The observations of surface morphology demonstrated that the colored microcapsules had a regular spherical morphology and a well-defined core-shell structure. The analysis of XRD and FT-IR confirmed the presence of amorphous SiO2 shell and the grafting reactive dyes, and the paraffin possessed high crystallinity. Compared with pristine paraffin, the thermal conductivity of paraffin@SiO2 colored microcapsules was significantly enhanced. The results of DSC revealed that the paraffin@SiO2 colored microcapsules performed high encapsulation efficiency and desirable latent heat storage capability. Besides, the examinations of UV-vis and TGA showed that the paraffin@SiO2 colored microcapsules exhibited good thermal reliability, thermal stability, and UV protection property. The analysis of infrared imaging indicated that the prepared latex paint exhibited remarkable temperature-regulated property. Compared with normal interior wall coatings, the temperature was reduced by about 2.5 °C. With such incomparable features, the paraffin@SiO2 colored microcapsules not only appeared well in their solar thermal energy storage and temperature-regulated property, but also make the colored latex paint coating have superb colored fixing capabilities

    Xingshi Yinyuan Zhuan is a full-length novel with 100 rounds, written in Shangdong dialect. Its writer is from Shangdong Province but his name and life story still remain unknown. We annotate the words/phrases in the novel and include 'comparison' this time. Modern Chinese Research Class students from Kumamoto University are investigating all the words/phrases occurring in the representative works produced in northern mandarin area in Qing Dynasty and currently are working on all the words/phrases from Xingshi Yinyuan Zhuan. That is to say, the essay aims to expound 'the rate of a certain word/phrase corresponding to its meaning', and researches on the quantitative linguistics with figures counting frequencies. Textual Research of Xingshi Yinyuan Zhuan from Hu Shi (1993) and Huang Suqiu (1981) contributes greatly to the annotation. Recently the Historical Evolution of the Dialect of Xingshi Yinyuan Zhuan (Chao Rui, 2014) and Dialect Vocabulary Dictionary of Xingshi Yinyuan Zhuan (Hitoshi Ueda, 2016) have been published one by one

    OpenKBP-Opt: an international and reproducible evaluation of 76 knowledge-based planning pipelines

    Objective: To establish an open framework for developing plan optimization models for knowledge-based planning (KBP). Approach: Our framework includes radiotherapy treatment data (i.e. reference plans) for 100 patients with head-and-neck cancer who were treated with intensity-modulated radiotherapy. That data also includes high-quality dose predictions from 19 KBP models that were developed by different research groups using out-of-sample data during the OpenKBP Grand Challenge. The dose predictions were input to four fluence-based dose mimicking models to form 76 unique KBP pipelines that generated 7600 plans (76 pipelines × 100 patients). The predictions and KBP-generated plans were compared to the reference plans via: the dose score, which is the average mean absolute voxel-by-voxel difference in dose; the deviation in dose-volume histogram (DVH) points; and the frequency of clinical planning criteria satisfaction. We also performed a theoretical investigation to justify our dose mimicking models. Main results: The range in rank order correlation of the dose score between predictions and their KBP pipelines was 0.50-0.62, which indicates that the quality of the predictions was generally positively correlated with the quality of the plans. Additionally, compared to the input predictions, the KBP-generated plans performed significantly better (P\u3c 0.05; one-sided Wilcoxon test) on 18 of 23 DVH points. Similarly, each optimization model generated plans that satisfied a higher percentage of criteria than the reference plans, which satisfied 3.5% more criteria than the set of all dose predictions. Lastly, our theoretical investigation demonstrated that the dose mimicking models generated plans that are also optimal for an inverse planning model. Significance: This was the largest international effort to date for evaluating the combination of KBP prediction and optimization models. We found that the best performing models significantly outperformed the reference dose and dose predictions. In the interest of reproducibility, our data and code is freely available
