Lonicerae japonicae Flos is a traditional Chinese medicine that has the effect is used for clearing away heat and detoxification. When stored improperly, this medicine is susceptible to mold growth, causing fungal contamination, reducing its safety and clinical efficacy. In order to understand the fungal contamination of Lonicerae japonicae Flos, we utilized the Illumina NovaSeq6000 platform to characterize fungal communities associated with five moldy Lonicerae japonicae Flos samples from warehouses in China via the sequencing of fungal internal transcribed spacer 2 regions. These analyses led us to identify 3 phyla, 5 classes, 7 orders, 9 families, 13 genera, and 20 species of fungi in these samples. Of these, Ascomycota was the dominant phylum, while Cysticomycetes, Ascomycetes, and Staphylococci were relatively dominant at the class level, and the most prevalent genera were Aspergillus, Penicillium, Xanthomonas, Microcystis, Talaromyces, and Erysiphe with relative abundance values of 79%, 21%, 94%, 100%, and 98%. In summary, in the present study we conducted the ITS-based comprehensive characterization of fungal communities associated with Lonicerae japonicae Flos for the first time. This approach aims to facilitate the early detection of fungal contamination in Lonicerae japonicae Flos, providing a theoretical basis for the study of anti-mold technologies.

One dimensional Wiener degradation process is often used to describe the degradation of product performance. However one dimensional Wiener degradation process doesn’t sufficiently consider the relevance of multiple degradation factors and wear process, which lead to inaccurate results. To overcome these problems, a new two dimensional Wiener stochastic degradation model is proposed, which applys to the products on wear process and stochastic degradation process. Combining wear model and two dimensional Wiener stochastic degradation model, a new reliability analytical form is obtained by constructing the Fokker-Planck equation. Then using the relation among wear volume, degradation characteristic lifetime and drift parameter, parameters of two dimensional Wiener degradation model on the basic of wear model can be estimated. Compared with the existing approaches, the proposed method can effectively improve accuracy. Finally, a case study is illustrated the application and advantages of the proposed method.

In our previous study, a prediction method of indoor temperature distribution based on the Contribution Ratio of Indoor Climate (CRI) and finite air temperature collected by one mobile sensor has been proposed. However, the CRI fixed value hypothesis limits its application in practical situations. In this regard, this study proposes to introduce interpolation POD (proper orthogonal decomposition) method to obtain the dynamic distribution of CRI, so as to improve the prediction accuracy. As a case study, in a simplified CFD model with identified heat source conditions, based on the interpolation POD method, the reconstruction of each sub temperature field dominated by only one heat source under any air supply parameters was realized, and thus its CRI distribution could be calculated. Then, by combining the finite air temperature collected by the mobile sensor, the indoor temperature distribution was predicted. The results showed that the introduction of interpolation POD method is effective, which breaks the application limitations of CRI fixed value hypothesis on the proposed method, and further promotes its development potential in the direction of "real-time prediction and dynamic regulation" in practical application.

The continuous rapid development of new infrastructure load represented by electric vehicles (EVs) has brought new opportunities and challenges to the power system, as well as new propositions for traditional power system load modelling. It is of great practical significance to study the planning and operation of power systems considering EVs and other new infrastructure loads. Based on the analysis of the real historical data of EVs, this paper proposes an EV load modelling method based on the charging power scenario model. Based on the key variables of EV charging, the proposed model considers the joint distribution model of the uncertainty and correlation of the key variables of EV charging. Power scenarios are aggregated to obtain the EV load curve. Finally, the actual EV charging power data is used to verify the effectiveness of the proposed method.

Circulation loss is one of the most serious and complex hindrances for normal and safe drilling operations. Detecting the layer at which the circulation loss has occurred is important for formulating technical measures related to leakage prevention and plugging and reducing the wastage because of circulation loss as much as possible. Unfortunately, because of the lack of a general method for predicting the potential location of circulation loss during drilling, most current procedures depend on the plugging test. Therefore, the aim of this study was to use an Artificial Intelligence (AI)-based method to screen and process the historical data of 240 wells and 1029 original well loss cases in a localized area of southwestern China and to perform data mining. Using comparative analysis involving the Genetic Algorithm-Back Propagation (GA-BP) neural network and random forest optimization algorithms, we proposed an efficient real-time model for predicting leakage layer locations. For this purpose, data processing and correlation analysis were first performed using existing data to improve the effects of data mining. The well history data was then divided into training and testing sets in a 3:1 ratio. The parameter values of the BP were then corrected as per the network training error, resulting in the final output of a prediction value with a globally optimal solution. The standard random forest model is a particularly capable model that can deal with high-dimensional data without feature selection. To evaluate and confirm the generated model, the model is applied to eight oil wells in a well site in southwestern China. Empirical results demonstrate that the proposed method can satisfy the requirements of actual application to drilling and plugging operations and is able to accurately predict the locations of leakage layers.

Artillery backlash angle is an important factor in firing accuracy. It is necessary to study the law of the change of the backlash angle in order to master the dynamic error of artillery rotating parts in the high and low direction. The vibration equation of backlash angle was deduced based on the force analysis of the rotating parts. The structure and physical parameters of artillery were selected, and the influence of different factors on the backlash angle was analyzed. The case analysis shows that the torsional rigidity of the high and low machine should be designed within an appropriate range according to the natural frequency of the vibration. The structure parameters of the gun have important influence on the vibration characteristics of the rotating parts. In the design of the gun, the center of the trunnion and the center of gravity should be located on the same side of the barrel axis. The research work provides a reference for the further study of the control of the backlash angle.

In this paper, the commonly used High Efficiency Particulate Air filter (HEPA) material as the research object, through the design of indoor experiment, using pure water, groundwater, and rainwater solution to soak, analysis of unused and abandoned the mesh in different water chemical solution release/adsorption law of anion and metal components, in order to find out its potential impact on the water environment. Results showed that: (1) when the waste HEPA filters were soaked in water solutions, the maximum average release amounts (Qmax¯)$$(\overline {{Q_{max}}} )$$ of four anions were in a order as: SO42−>NO3−>Cl−>F−$${\rm{SO}}_4^{2 - } > {\rm{NO}}_3^ - > {\rm{C}}{{\rm{l}}^ - } > {{\rm{F}}^ - }$$. Pure waters showed the highest (Qmax¯)$$(\overline {{Q_{max}}} )$$ of Cl- and NO3−$${\rm{NO}}_3^ - $$, which were 1.2120 and 0.3387 mg/g, respectively. Groundwater showed the highest (Qmax¯)$$(\overline {{Q_{max}}} )$$ of SO42−>$${\rm{SO}}_4^{2 - } > $$ and F-, which were 6.7329 and 0.0348 mg/g. These indicated that SO42−>$${\rm{SO}}_4^{2 - } > $$ was the major anion pollutant for waste HEPA filters soaked in water solutions, and groundwater and pure water were more susceptible to be contaminated by anions released from waste HEPA filters. (2) the (Qmax¯)$$(\overline {{Q_{max}}} )$$ of three metals released from waste HEPA filters were in a order as Zn> Pb> As, in which, groundwater showed the highest (Qmax¯)$$(\overline {{Q_{max}}} )$$ of Zn (2.21 μg/g), followed by rainwater and pure water. This meant that Zn is the major heavy metal pollutant released from waste HEPA filters into the water environment, and groundwater was more susceptible to be contaminated by metals released from waste HEPA filters. (3) None Zn, Pb, and As were released in these three different solutions for the unused filter, indicating that it has almost no contamination threat to the water environment. This study is expected to further improve the understanding of water environmental pollution prevention and management, and provide a theoretical basis for China’s ecological environment protection.

In view of the large demand for new coronary pneumonia covid19 image recognition samples, the recognition accuracy is not ideal. In this paper, a new coronary pneumonia positive image recognition method proposed based on small sample recognition. First, the CT image pictures are preprocessed, and the pictures are converted into the picture formats which are required for transfer learning. Secondly, small-sample image enhancement and extension are performed on the transformed image, such as staggered transformation, random rotation and translation, etc.. Then, multiple migration models are used to extract features and then perform feature fusion. Finally,the model is adjusted by fine-tuning. Then train the model to obtain experimental results. The experimental results show that our method has excellent recognition performance in the recognition of new coronary pneumonia images, even with only a small number of CT image samples.

To study the collapsibility of typical loess and its influencing factors in different areas, the samples in Jingyang, Lanzhou and Yili were studied. The correlation between initial moisture content, dry density, composition of particle size, structural parameters and the coefficient of subsidence is analyzed. The results show that: the coefficient of collapsibility is negatively correlated with the initial moisture content and dry density. In the experiments of multiple groups, the collapsibility coefficient has a certain correlation with the clay content, but not a uniform correlation with the particle content. The collapse coefficient is approximately positively correlated with the composite structure potential.

The evaluation index system of ecological performance of beautiful rural construction was initially constructed with 2 first-class indexes, 11 secondclass indexes and 29 third-class indexes in order to improve the rural ecological space environment, enhance the rural ecological civilization, develop the quality of life of villagers, and promote rural revitalization.

This article mainly analyze the shortcomings of the inherent peak shaving auxiliary service mechanism in the high-proportion of new energy access scenarios in Northeast China, which restricts the enthusiasm of thermal power units to participate in peak shaving. For this reason, a dynamic peak shaving compensation benchmark is proposed which follows load changes. At the same time, in order to standardize market behavior and facilitate market supervision, a guiding formula is proposed for quotation of thermal power units. Based on the above, a dynamic auxiliary service market mechanism is established which used actual operating data of Liaoning province power grid as a calculation example to verify that the mechanism can effectively improve the enthusiasm of thermal power units to participate in peak shaving, which is conducive to market operation and supervision as well.

In mid-latitude glaciers, the altitude of the snowline at the end of the ablating season can be used to indicate the equilibrium line, which can be used as an approximation for it. In this paper, Urumqi Glacier No.1 was selected as the experimental area while Landsat TM/ETM+/OLI images were used to analyze and compare the accuracy as well as applicability of the visual interpretation, Normalized Difference Snow Index, single-band threshold and albedo remote sensing inversion methods for the extraction of the firn lines. The results show that the visual interpretation and the albedo remote sensing inversion methods have strong adaptability, alonger with the high accuracy of the extracted firn line while it is followed by the Normalized Difference Snow Index and the single-band threshold methods. In the year with extremely negative mass balance, the altitude deviation of the firn line extracted by different methods is increased. Except for the years with extremely negative mass balance, the altitude of the firn line at the end of the ablating season has a good indication for the altitude of the balance line.

In order to study the interaction between the left and right tunnels of suspension bridge tunnel-type anchorage, the finite difference numerical software is used to analyze the mechanical properties of the surrounding rock during the construction process. A numerical analysis model based on FLAC3D is established to analyze the stress, displacement and plastic zone changes of the surrounding rock of right tunnel anchor cavern during the construction of left tunnel anchor cavern. The right tunnel anchor cavern is excavated firstly, and then the left tunnel anchor cavern is excavated. The numerical simulation results show that the main displacement of the right tunnel occurs in the construction stage of the anchor plug body and the rear anchor cavern of the left tunnel. During the excavation of the left tunnel, the plastic zones of the left and right tunnel anchor caverns are only connected above the middle of the waist wall. Therefore, it is suggested that during the construction process, especially in the excavation stage of the anchor plug body and the rear anchor cavern, the area above the middle of the tunnel waist wall should be strengthened in time to ensure the construction safety.

Ecological systems are essential in maintaining a good living environment for human beings. However, human beings usually focus on the benefits they can gain from the ecosystem by developing the land and ignore the degradation of environment. In this paper, we will offer an ecological services evaluation model to measure the value of ecological services and provide land use planners with a method to compute the true economic costs of the land use development projects. First, we define ecological services value (ESV), which means the value of the benefits that ecosystem can provide. Then, we classify the functions of ecosystem into five kinds: water purification, climate regulation, air purification, biodiversity conservation and vegetation conservation. For each function, we choose a related index to measure the performance. After the classification, we adopt Analytical Hierarchy Process (AHP) to calculate the weight for each of the function and do the consistency test; second, we apply knowledge of economics to study the true economic costs; third, after getting the equation of the true economic costs, we realize it in the cost-benefit analysis. We offer two case studies to analyze the small community-sized project and large national project respectively; fourth, we take ten examples including U.S., Switzerland and China to apply our model in practice. We fit data and find the average level of land use percent over time, and form a model with differential equation in order to calculate the time-varying model of ESV; fifth, we focus on humanities field to explore the impacts on land use project planners and managers. They should not only be responsible for environmental degradation and monitor environmental index carefully, but also pay for the benefits which were ever owned by human beings before land development. In order to make our work more accurate and complete, we use SWOT Analysis across the analytical process. Finally, we promote our model and extend the factors from six to twelve, which increases the accuracy.

With the development of liquefied natural gas(LNG) port, as one of the crucial LNG port sitting process, the LNG terminal site’s condition assessment method has always received attention from experts, scholars concern more and more about the method’s practicality and reliability. In the traditional condition assessment method, due to the characteristics of the complex and extensive factors in the comprehensive assessment of the LNG terminal site, the assessment system is not comprehensive enough, or the assessment is too complex, the indexes are not easy to quantify, such problems are emerging. In view of the above reasons, the principal component analysis(PCA) method is used to transform the multi-indicators that affect the comparison of terminal sites into a few comprehensive indicators. A comprehensive evaluation model of the LNG terminal site based on cloud matter element theory and subjective and objective comprehensive weighting method was constructed. By the subjective and objective comprehensive weighting method, the comprehensive weight of each index is determined and the LNG terminal site comprehensive assessment standard cloud element model is constructed with the combination of cloud model and matter-element theory. The cloud matter-element correlation function is established to determine the degree of association between the matter element to be evaluated and the standard cloud matter element model. In order to eliminate random errors and improve the credibility of the results, the algorithm is used for multiple calculations and analysis to achieve the purpose of simultaneously giving the evaluation results and coefficients of credible degree. Finally, the reliability and rationality of the method are verified by an example.

Nondestructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. As one of unconventional NDT technology, laser ultrasonic technique (LUT) have played an important role in inspecting the materials in some extreme environments, such as high temperature, high pressure, corrosion, radioactive and etc. LUT uses lasers to generate and detect ultrasonic waves in a noncontact way. Thus, compared with the traditional ultrasonic technique, LUT has the advantages of high precision, high sensitivity without requirement for geometry of target material. So far, LUT has been well applied to composite inspections for the aerospace industry and on-line hot tube thickness measurements for the metallurgical industry. This talk describes the application of LUT on flaws detection in rail and thermal barrier coatings.

Urban flooding and water pollution are urgent problems to be solved in urban development. The improvement of urban drainage and water quality in urban construction using ecological measures is an important research task.

After comparing the structural weight, the design models of blocker door are built for kinematic analysis of relevant mechanism and simulation. The results show that simplified design and elimination of multiple interfaces generates weight saving, O-duct improves airflows within the engine, meanwhile D-duct has excellent cost effective and maintainability.

Clock transform and recovery is of significant importance in microwave TDM service, and it is always extracted from the E1 line data stream in most cases. However, intrinsically uncertain delay and jitter caused by packet transmission of E1 data information, may lead to the indexes of the data recovery clock exceed the clock performance template. Through analysis of the E1 clock indexes and measuring methods, this paper proposes a new clock recovery method. The method employs two buffers, the first RAM is used as a buffer to deduct excess information, and the second FIFO is used as a buffer to recovery the clock and data. The first buffer has a feedback from the second one, and is able to actively respond to changes in the data link and requests from the second one. The test results validate the effectiveness of the method, and the corresponding scheme is also valuable for the other communication systems.

The smart car is designed based on Freescale’s MC9S12XS128 and a linear CCD camera. The linear CCD collects the road information and sends it to MCU through the operational amplifier.

Finally, the PD control algorithm is used to regulate the smart car’s turning angle to make the smart car respond quickly while the smart car is passing the curve path. The smart car can realize the self-balancing control of two wheels and track automatically the black and while lines to march.

By using optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), electron back scattered diffraction (EBSD) and tensile test, the effect of annealing temperature on microstructure and mechanical properties of a high Al-low Si TRIP steel was investigated. The results show that TRIP effect can be obtained when annealing temperature is above Ac3 due to the existence of δ-ferrite in this high Al-low Si TRIP steel. That is to say, the microstructure consisting of ferrite, bainite and retained austenite can be obtained when annealing temperature is above Ac3. Furthermore, the tensile strength and the product of strength and elongation decrease with increasing annealing temperature when annealing temperature is above Ac3.

Wampee is one of the characteristic fruits in southern China, and its brittle and thin skin can easily be damaged. In this study, principal components analysis (PCA) and minimum noise fraction (MNF) analysis were carried out on the two wampee varieties by hyperspectral imaging technology, and 680nm was determined to be the optimal characteristic wavelength. The accurate recognition rate obtained from PCA algorithm for wampee samples of two varieties was about 83.75%, and that obtained from MNF algorithm for two variety samples was 85%. It was indicated that the wampee damaged can be identified more accurately and effectively by MNF based on hyperspectral imaging technology

Concrete sandwich panel is a kind of building element with the characteristics of light weight, high strength, suitability for standardized production, meanwhile it has the multi-function of heat preservation and sound insulation which can be used not only as enclosure components, but also as structural components for multi-story residential buildings. A novel sandwich wall system has been presented in this work with an innovative design concept. Compared with traditional steel wire sandwich panel, this sandwich panel wall system has unique features such as prefabricated steel system, core column with spiral stirrup, foamed concrete as insulation layer. This wall system also meets the national policy requirements in energy-saving and has potential application and development prospects. In this paper, Finite element method is used to simulate and analyze the seismic performance of this new sandwich wall panel. The results show that the panel with 3D steel wire has greater stiffness and better earthquake resistance than panel with planar steel wire mesh.
