With the development of information technology and the increasing complexity of industrial technology, there is an urgent need for a certain field to use big data and artificial intelligence to improve the management and decision-making level. In order to classify the field’s risk text data through intelligent algorithms, analysing the risk distribution and the major problems, this paper researches on the annotation methods of training data in this field. The proposed data annotation method is based on pattern matching, addressing the special problems of risk data annotation in this field (such as strong professionalism, small data volume, high accuracy requirement and timeliness requirements). A new matching pattern is generated through the steps of text segmentation, keyword extraction, pattern preliminary generation, pattern relation tree construction, pattern optimization, pattern generalization, pattern verification, classification and annotation, and final classification and annotation are performed after pattern matching. Performance tests in terms of accuracy, recall rate, and annotation time have shown that the overall performance of the proposed method outperforms that of traditional item-by-item manual annotation, and semi-automatic annotation methods through machine learning. The method described in this paper has strong application value for risk data annotation in this field, and also has certain reference significance for high-density, high-accuracy and high-timeliness data annotation in other fields.

In recent years, there have been frequent offshore oil spills, and the discharge of industrial oily wastewater has not been properly solved, seriously affecting biological and water quality, and people's requirements for water quality are getting higher and higher, so it has become increasingly urgent to find green and efficient technologies and methods for separating oil-water mixtures. In this work, glutaraldehyde, a widely used crosslinker, is used to graft natural polysaccharide chitosan onto PVDF membrane, which greatly enhances the hydrophilicity of PVDF membrane, and the superhydrophilic superoleophobic CG-PVDF membrane prepared can be used to treat oily wastewater. The materials for preparing membranes are inexpensive, easy to obtain, and environmentally friendly, recyclable, and will not cause secondary pollution. Therefore, this green and simple membrane separation method for the treatment of oily wastewater is of great significance in sustainable development.

In recent years, equity pledge has gradually become an emerging financing method for enterprises to solve financing difficulties, which has attracted the attention of many shareholders and financial institutions. As an important driving force for enterprises to carry out economic transformation and upgrading, innovation can also effectively enhance their core competitiveness in the same industry. This paper selects the data of China’s A-share ChiNext listed companies from 2013 to 2021 as the analysis object, and studies the impact of equity pledge and corporate R&D investment and the intermediary role played by financing constraints, and the results show that the equity pledge of controlling shareholders is significantly negatively correlated with corporate R&D investment, and the inhibition effect is more obvious with the increase of equity pledge ratio. In addition, this paper finds that financing constraints play a partial intermediary role in the relationship between controlling shareholders’ equity pledge and enterprise innovation. In response to this situation, this paper puts forward corresponding countermeasures and suggestions.

At present, the stress-strain test of pile body mainly focuses on precast pile and cast-in-place pile with reinforcement, and this is mainly because the pre-assembly of test components can be carried out in the pile body or reinforcement cage before the prefabricated pile is formed. When the pile is formed, it could be embedded together with the pile body or reinforcement cage. But for the cast-in-place plain concrete pile field test research report is rare. In view of the shortcomings of the existing test methods in the test of plain concrete piles, the resistance strain gauge and inclinometer are improved to realize their application in the field test of plain concrete piles, which is employed for the deformation characteristics test of plain concrete pile under horizontal load. The test results show the applicability of the improved test method, which provides useful references for similar research.

By synthetically applying order tracking method and acoustic holography method, the noise source of the electric vehicle motor was discerned in the bench test. According to profiling of the test data, the motor noise order tracking diagrams and sound holography contour maps were employed to draw the noise map of the electric vehicle motor. It was revealed that the low and medium frequency components of the motor’s noise are mainly related to the rotational passing frequency of the bearing rolling element and cage, as well as the doubling frequencies of the rotational frequencies of the rotor. The medium and high frequency components of motor’s noise are mainly related to motor’s loads and speeds. In the 1000-2500 r/min speed stage of the motor with load, the main order of motor’s noise is the 72nd order and in the speed stage of 3000-5000 r/min, motor’s noise is mainly the 15th, 18th and 26th orders. When the motor speed increases from 5000r/min to 8000r/min, the main order of motor’s noise is the fourth order. When the motor was accelerated in no-load operation, its noise characteristics are different from those of the motor with load. When the motor run at no load and low speed, the 16th and 72nd order are the main order of motor noise, while at high speed, the 2nd order of motor noise and the orders of motor switching frequency noise caused by frequency converter are the main order of motor noise. The above conclusions will give the assistance to further research on the acoustic characteristic of the electric vehicle motor.

As a rising power with a global outlook, China has been regarded as a potential model for the developing countries in the 21st century. Yet, the United States is still the solo superpower as widely recognized. Given that the world's two most important countries now race for their own influences globally, it is critical for both sides to find as many ways as possible to keep lines of communication between them open. The reasons are self-evident since knowledge brings mutual understanding. The lack of reciprocity breeds suspicion, miscalculation, and both hot and cold war. There is no assurance that the two nations can always be best of friends, but there are indeed the potentials of a vigorous partnership. Truly, ignoring each other and the Thucydides trap can be our undoing by working together to concede our differences offers hope not only to the citizens of both countries but to the whole world who are affected by the Sino-US relationship.

The removal efficiency of nitrogen and phosphorus is challenging in the conventional biological nitrogen and phosphorus removal processes. In this study, the modified pyrite was used as the fillings of se-quencing batch reactor (SBR) in order to improve the efficiencies of nitrogen and phosphorus removal from wastewater. The results showed that SBR with the modified pyrite could significantly improve the removal efficiencies of nitrogen and phosphorus when compared with that in SBR without fillings (control SBR). The average influent ammonia nitrogen (NH4+-N) and total phosphorus (TP) were 6.96±0.17 mg L-1 and 6.94±0.01 mg L-1, respectively. The average NH4+-N and TP removals of modified pyrite constructed SBR were 49.65±19.49% with 3.54±1.31 mg L-1 of average effluent NH4+-N and 76.20±6.55% with 1.84±0.46 mg L-1 of average effluent TP, respectively. While the average NH4+-N and TP removal efficiencies of con-trol SBR were only 34.76±11.28% and 56.28±0.11%. The mechanisms of the SBR with enhanced simulta-neous nitrogen and phosphorus removals might be anaerobic and aerobic oxidations of modified pyrite, and phosphorus retained in the SBR of modified pyrite was mostly in the form of Fe-bound-P.

In recent years, higher demands for offshore pipeline design of deepwater installation are put forward. This paper mainly aims to investigate the influence of pipelay parameters on dynamic tension behaviour of deepwater S-lay pipeline to optimize the design of pipe structure and tensioner. A full finite element model for deepwater S-lay systems is developed to simulate the dynamic response of offshore pipeline from the pipelay vessel via stinger to the seabed. The influences of water depth, outer diameter and submerged self-weight of the pipe, and stinger length on the dynamic tension behaviour of the pipeline have been quantitatively studied. A strong relevance between the axial tension of offshore pipeline and pipelay parameters is observed, which offers very intuitive evidences for the design of pipe structure and tensioners.

Credit risk has been a widespread and deep penetrating problem for centuries, but not until various credit derivatives and products were developed and novel technologies began radically changing the human society, have fraud detection, credit scoring and other risk management systems become so important not only to some specific firms, but to industries and governments worldwide. Frauds and unpredictable defaults cost billions of dollars each year, thus, forcing financial institutions to continuously improve their systems for loss reduction. In the past twenty years, amounts of studies have proposed the use of data mining techniques to detect frauds, score credits and manage risks, but issues such as data selection, algorithm design, and hyperparameter optimization affect the perceived ability of the proposed solutions and it is difficult for auditors and researchers to explore and figure out the highest level of general development in this area. In this survey we focus on a state of the art survey of recently developed data mining techniques for fraud detection and credit scoring. Several outstanding experiments are recorded and highlighted, and the corresponding techniques, which are mostly based on supervised learning algorithms, unsupervised learning algorithms, semisupervised algorithms, ensemble learning, transfer learning, or some hybrid ideas are explained and analysed. The goal of this paper is to provide a dense review of up-to-date techniques for fraud detection and credit scoring, a general analysis on the results achieved and upcoming challenges for further researches.

Hot compression experiments were conducted on a Cu–Ag–Zr alloy with low Ag content, Cu–3Ag–0.6Zr, to investigate the effect of precipitation on the mechanical response of this alloy. The results show that the stress-strain behavior of Cu–3Ag–0.6Zr alloy is significantly affected by the precipitation. The flow stress of the alloy deformed at temperatures of 623–673 K and a strain rate of 10−3 s−1 increases due to the occurrence of the continuous and discontinuous precipitation. However, the precipitation process is suppressed with increasing strain rate, resulting in almost identical flow stress of the alloy deformed at different temperatures.

Hot compression tests of the Cu–3Ag–0.6Zr (wt.%) alloy were carried out on a Gleeble-3800 testing machine at various strain rates and at different deformation temperatures. The stress–strain behavior of the alloy during the deformation process are analyzed. The results show that the hot deformation behavior of the Cu–3Ag–0.6Zr alloy is markedly affected by the interaction between the work hardening and the dynamic recrystallization at different strain rates and temperatures. The thermal deformation activation energy is calculated as 248.8384 kJ mol−1 and the hot compression constitutive equation has been established. The processing map of the alloy has also been established. According to the obtained processing map, the preferable domains for hot working are identified at a strain rate of 10-3 s-1 and at 900–940 K or temperatures higher than 1023 K.

Food asset mapping is gaining prominence in Canada as an important planning tool for the evaluation of local food systems. In addition to being used by planners to identify opportunities for improved food security, food asset maps are also valuable references for sourcing food locally, particularly by people experiencing food insecurity. Seventy-three food asset maps were reviewed and categorized based on the types of food assets included as well as design characteristics. Built environment assets such as grocery stores and food banks were included in most maps, as were agriculture-based natural food assets like farms, community gardens, and orchards. However, representations of Indigenous-focussed food assets and natural food assets that are not agriculture-based, such as forests, water bodies, and foraging areas, were generally lacking. The lack of representation of Indigenous perspectives on what is considered a food asset reinforces the values of a settler-colonial food system in food asset maps. The methods for food asset mapping therefore need to be changed from current quantitative practices that largely rely on secondary data sources led by governments and non-profit organizations to collaborative approaches that centre the perspectives of Indigenous peoples and other equity deserving groups.

The paper focuses on the lectures given by Piero Calamandrei in 1952 at the University of Mexico, which were collected in the famous volume Processo e democrazia published by Cedam in 1954. The volume, translated in China in 2005, has aroused lively interest among Chinese scholars. The Author expresses his appreciation for the scholarly tradition stemming from Calamandrei and, in particular, he emphasises the profile of judiciary’s autonomy and independence, which distinguishes liberal and democratic systems from authoritarian ones. Lastly, the Author dwells on the relationship between judges and lawyers, which should take place in a climate of active and mutual trust.

This paper aims to present a systematic overview of metadiscourse discourse studies published in different sources, examine the structure of scientific collaboration, identify hot research areas, and trace the research trends. To meet this objective, the bibliometric records of metadiscourse-related publications are first retrieved from the Web of Science Core Collection. Then, the bibliometric analysis and social network analysis are employed to analyze the retrieved bibliometric databased with bibliometrix and VOSviewer. Our bibliometric analysis shows that the overall trend of metadiscourse-related publications has been on the increase, with a relatively slow growth before 2011. It also identifies the most productive journal, the top prolific author, the top productive institution and country. On the other hand, the social network analysis yields collaboration networks, and keyword-based co-occurrence networks. The collaboration networks show the most fruitful co-author collaboration network, and the most productive co-institution network, and the most productive co-country network. The keyword-based co-occurrence network sketches major research areas and detects their changing trajectory. Hence, the findings are expected to help orient novice researchers to metadiscourse studies, and offer the insights for future researcher to address the emerging issues of metadiscourse.
