With the development of digitalization, industrial control network have more connections and open to external network, which breaks their “isolation” from Internet and makes them more vulnerable to be attacked especially by malicious code. To model and analyze the impact of different containment strategies for attacks by malicious code in the industrial control network, the SUIQMR model is established to simulate malicious code propagation. Since the industrial control network is often coupled with Internet, industrial control coupling network is also considered in the SUIQMR model and the containment strategies of quarantine,benign worms and honeypot are added into the model to evaluate their effect against malicious code propagation.The simulation results show the effectiveness of our model.

At the Echigo-Tsumari Art Triennial, artists used the countryside as a stage for their artworks. The Echigo-Tsumari region has also taken this opportunity to revive its economy and rural culture. And the inspiration from this case is something that cannot be ignored in China today. This article analyzes the Echigo-Tsumari Art Triennial and some Chinese local arts festivals, go a step further and taking advantage of the advantages of China's Internet in logistics and information dissemination to extend the cultural strategy of combining rural culture with art.

In this paper, we take advantage of a class of one-generator generalized quasi-cyclic (GQC) codes of index 2 to construct quantum error-correcting codes. By studying the form of Hermitian dual codes and their algebraic structure, we propose a sufficient condition for self-orthogonality of GQC codes with Hermitian inner product. By comparison, the quantum codes we constructed have better parameters than known codes.

In the recovery of low permeability reservoir, the capillary pressure has an important effect, which may reduce gas production. Due to the capillary end effect, there are two flow patterns in the vicinity of the production well: both water and gas phases can flow into the production well and only gas phase can enter the production well. Based on the analytical equations of one-dimensional radial flow considering the capillary end effect, an alternative numerical well model for low permeability gas reservoir is constructed. Numerical examples show that the proposed model can reflect the dramatic change for saturation and gas-phase pressure in the vicinity of the production well both for two flow patterns, and therefore can predict the gas and water productions accurately at different grid scales. In contrast, the original Peaceman well model for multi-phase flow, which is directly extended from that for single-phase flow, only can provide good prediction under the condition of that the grid size is enough small. Especially, for the original Peaceman well model, this problem is out of control since it is difficult to estimate a suitable grid size.

With the aim of providing an integrated understanding of how self-esteem and self-compassion interact to influence subjective well-being, specifically how is it explained by the dual process model of information processing, this essay reviewed the insights obtained from studies examining the nature of self-esteem, the dual process model in explaining the explicit-implicit self-esteem discrepancies, and the role of self-compassion in modulating the relationship between different type of combinations of implicit and explicit self-esteem and subjective well-being. It is concluded that, firstly, high self-esteem can be both the product of the self-verification process where individuals deem that they have accomplished the role of their identities and the psychological buffer by which individuals attenuate the anxiety of death. Secondly, the distinction between associative and propositional processing paves the way for explicit-implicit self-esteem discrepancies. Thirdly, when individuals are both low explicit self-esteem and implicit self-esteem, self-compassion as a propositional process could override associative processes to reduce negative affect; for individuals with both low explicit self-esteem and low implicit self-esteem, self-compassion could reduce people’s defensive tendencies.

The Healthy Cities and Sustainable Development Goals are interlinked, and the Healthy Cities movement has received widespread response and support worldwide over the past 30 years. The European Healthy Cities Networks covers about 1,400 cities. China started the Healthy Cities Movement in 1994 and put forward the Healthy China Strategy in the report of 19th national congress of CPC. Based on the impact of COVID-19 and Henan floods on urban health, it is necessary to incorporate some unconventional indicators into the Healthy Cities evaluation indicator framework. In addition, structured data cannot fully describe certain indicators, so the collection of unstructured data is equally important.

Pressure response behavior of two-layered reservoir with a vertical mixed boundary is easy to be mistaken for that of the radial composite reservoir or dual-pore reservoir. It is difficult to fit the pressure response curve and easy to obtain abnormal parameter values using a misunderstood model. In this paper, we present the interpretation of three different types of pressure responses of vertical mixed boundary reservoir by our proposed models, where the diagnostic window and feature value are captured for different mixed boundary types. Results show that the mixed boundary with closed boundary and infinite-acting boundary induces the fake pressure response of a radial composite reservoir with poor permeability outer zone. The mixed boundary with the main constant-pressure and non-main closed boundary produces a fake pressure response of a dual-porosity reservoir. The diagnostic window of pressure response curves shape can easily capture the mixed boundary type, and the feature value of the feature values of pressure response value can quickly obtain the permeability ration of one layer. Aiming at different representative types of pressure response cases in the western Sichuan XC gas field, China, we innovatively analyze them from a different perspective and get a new understanding of pressure response behavior of vertical mixed boundary, which provides a guideline for the interpretation of layered oil and gas reservoir with the complex boundary in the vertical direction.

The experiment was conducted to study the tendency of the change of flavonoids content in pomelo during its growth and development and the characteristics of flavonoids accumulation in different cultivars Guanximiyou. The dried samples of the exocarp, mesocarp, and pulp of Sanhongmiyou and Huangjinmiyou were used for measuring the content of total flavonoids. The results showed that the content of total flavonoids in exocarp decreased first and then increased during growth and development, while the content in mesocarp did not change obviously. Furthermore, the content in pulp showed a decreasing trend. The content in exocarp was the highest at the earlystage, while in mesocarp was the highest at the mature stage of the fruit. The content of total flavonoids in exocarp and pulp of Sanhongmiyou was higher than that of Huangjinmiyou, total flavonoids content in the exocarp of Sanhongmiyou was similar to Huangjinmiyou within 150 days after anthesis. In addition, the variation trend of the two cultivars was consistent throughout the whole growth and development.

In order to study the effect of different planting areas on the color of Pomelo cv. Huangjinmiyou fruit, Pujiang and Guang’an Pomelo cv. Huangjinmiyou were used in this experiment. Brightness, red and green deviation and blue and yellow deviation of exocarp, mesocarp and pulp parts in the test samples were measured, and the composite index of color difference was calculated. The results showed that the comprehensive index of color difference in the exocarp and pulp of Pomelo cv. Huangjinmiyou from the two planting areas changed almost synchronously. But it was negative at 90 days after anthesis and positive at 120 days after anthesis in the mesocarp of Pujiang pomelo. It was still negative at 150 days after anthesis in the mesocarp of Guang’an pomelo until 180 days after anthesis. It reflects the comprehensive index of fruit color displayed by the accumulation of carotenoids. The external environment stimulates the accumulation of carotenoids. Therefore, color variation difference may be caused by different environmental factors in the two regions.

The role of constraint energy-saving policy (ESP) playing in the coordinated development of energy conservation, emission reduction, and economic growth is of great significance to the country's sustainable progress. Applying a non-radial and non-oriented DEA model incorporating innovation output and multiple undesirable outputs, this paper measures the green production performance (GPP) of China's industrial sectors from 2002 to 2015. And then the effect of implementing energy-saving policy on GPP is investigated through Quasi-difference-in-differences (Quasi-DID) method. The results show that China's industrial GPP rises during 2002-2004 and then declines with fluctuations. Technology change (TC) is the dominant driver. Energy-saving policy positively affects industrial GPP in general yet further dynamic analysis reveals that such a positive effect remains unstable and finally manifests a reverse impact at the end of every five-year-plan period. Therefore, China should properly introduce market mechanisms, formulate comprehensive policy mix strategies to balance sustainable improvement of industrial economy and ecological environment.

This research evaluates the cooling performance of trailing-edge cutback for gas turbine blade. By using DES based on SST k-ω turbulence model, numerical investigations were performed at two steps: first, to validate simulation results from an existing TE cutback cooling with staggered pin-fin arrays inside the cooling passage against experimental measurement. Three types structured mesh from coarse (Δy+ = 0.74) to fine (Δy+ = 1.22) were evaluated during this step; second, to investigate the TE cutback cooling performance on various blowing ratios. Simulations were performed by keeping the same initials and boundary conditions as the experiment. The result indicates that validation can be considered acceptable by controlling grid quality resolution near wall regions. Both computational data of the adiabatic film-cooling effectiveness and the discharge coefficient are in good agreement with available experimental measurements. The averaged film-cooling effectiveness along the cutback region is highly influenced by the blowing ratios, which is to be related to the turbulent flow structures formed at the mixing region as the impact of coolant flow ejection. The increase of coolant jet velocity triggers the heat transfer process up to the downstream region of TE cutback cooling.

The pyrolysis and combustion characteristics of a waste oil absorbing activated carbon were investigated using a thermogravimetric analyzer under heating rate of 10°C/min from 25°C to 1000°C. The activated carbon sample was used to adsorb waste oil. The results obtained, indicates that DTG curves of the pyrolysis process of the sample has three peaks at 106°C, 190°C and 249°C. The four peaks are observed in the DTG curves of the incineration process. The first peak at 110°C is caused by water emission. The second peak corresponds to the temperature of 190°C that is consistent with the second peak temperature of the pyrolysis process of the sample. The third peak at 240°C which is 9°C lower than the third peak temperature of the pyrolysis process. The second and third peaks maybe caused by the emission of the waste oil absorbed in the activated carbon. The fourth peak temperature is 516°C and the weight loss within the range of 400°C ~ 560°C is more obvious. The weight loss is caused by the residue char combustion.

As pointed out in several previous works, new drying technologies must be developed to ensure lignite remained competitive. In order to design and test them, it was needed to have a better understanding of the characters of water in lignite. Using differential scanning calorimetry (DSC), three types of the water storing in the lignite were determined from congelation character. The contents of the free water and bound water were experimentally measured from their heats of congelation, respectively. The results shows that the congelation temperature and the freezing heat per weight unit of the bound water vary in different types of lignite. It is deduced that the bound water in lignite can reflect the character of lignite. Besides, the total water content of free water and bound water is less than that measured by fully drying at 105°C. Therefore, it is deduced that there is a kind of water not frozen in the lignite, possibly because its molecular cluster is too small.

Cellwall invertase (CWIN) hydrolyzes sucrose into glucose and fructose irreversibly, playing key roles in carbohydrate partitioning and plant defence. MeCWINV1 is one of the CWINs in cassava, which contains several light-responsive elements and stress-responsive elements in promoter region. To analyze the regulatory function of MeCWINV1 in the cassava starch accumulation and stress defense response, a 865 bp MeCWINV1 promoter fragment was cloned and inserted into yeast one-hybrid bait vector to construct pCW1-AbAi vector, then was transformed to Y1HGold yeast strains to screen the binding proteins. It might provide a framework for further investigation on the regulation mechanism of MeCWINV1 gene in cassava.
