The main problem faced by ethanol oxidation reaction(EOR)includes low activity,poor selectivity,and durability.In the study,we found that polysulfide modified on the surface of PtCu intermetallic(IM)/C can simultaneously enrich hydroxyl and ethanol,which could effectively improve the catalytic activity,CO_(2) selectivity,and durability of catalyst.The mass activity and the specific activity of the product in 1 M KOH electrolyte reached 17.83 A·mgPt^(-1) and 24.67 mA·cm^(-2).The CO_(2) selectivity of polysulfide modified product achieved 93.5%,which was 30 folds higher than Pt/C.In addition,the catalyst showed high catalytic stability.The mechanism study demonstrates that the surface modified polysulfide could significantly boost the enrichment effect of ethanol and hydroxyl species,accelerating C–C bond cleavage and CO oxidation.

Cryptomining Malware Detection Based on Edge Computing-Oriented Multi-Modal Features Deep Learning

引用

China Communications 2022年第2期19卷 174-185页

作者： Wenjuan Lian Guoqing Nie Yanyan Kang Bin Jia Yang Zhang college of Computer Science&Engineering Shandong University of Science and TechnologyQingdaoShandong 266590China college of foreign languages Shandong University of Science and TechnologyQingdaoShandong 266590China

In recent years,with the increase in the price of cryptocurrencies,the number of malicious cryptomining software has increased significantly.With their powerful spreading ability,cryptomining malware can unknowingly occupy our resources,harm our interests,and damage more legitimate assets.However,although current traditional rule-based malware detection methods have a low false alarm rate,they have a relatively low detection rate when faced with a large volume of emerging malware.Even though common machine learning-based or deep learning-based methods have certain ability to learn and detect unknown malware,the characteristics they learn are single and independent,and cannot be learned adaptively.Aiming at the above problems,we propose a deep learning model with multi-input of multi-modal features,which can simultaneously accept digital features and image features on different dimensions.The model in turn includes parallel learning of three sub-models and ensemble learning of another specific sub-model.The four sub-models can be processed in parallel on different devices and can be further applied to edge computing environments.The model can adaptively learn multi-modal features and output prediction results.The detection rate of our model is as high as 97.01%and the false alarm rate is only 0.63%.The experimental results prove the advantage and effectiveness of the proposed method.

ENTREPRENEURIAL OPPORTUNITY,VALUE EVOLUTION,AND ORGANIZATIONAL INTEGRATION OF PROFESSIONAL FARMER ENTREPRENEURSHIP:A MULTI-CASE COMPARISON IN CHINA

引用

Frontiers of Agricultural Science and Engineering 2023年第1期10卷 135-148页

作者： Yifeng ZHANG Chunfang YANG Bright OBUOBI Martin Kobby GRANT college of Management Shandong Vocational University of Foreign AffairsRushan 264504China college of Economics and Management Nanjing Forestry UniversityNanjing 210037China

A comparative multi-case analysis of professional farmer entrepreneurship cases in China was performed by applying the structural hole theory.The results confirmed four views.(1)Choosing the modern agriculture project entrepreneurship is rational for professional farmers,who return from urban,to reduce the interference from non-market factors.The success of this project stems from its ability to successfully occupy the structural hole of the market trading network.(2)In economically developed areas,professional farmers start their businesses and reduce transaction costs with factors by occupying‘self-benefit’or‘mutual-benefit’structural holes in market networks.(3)In traditional agricultural areas,for reducing factor transaction costs,professional farmers occupy the organizational-governance structural hole of rural social relationship networks and the mutual-benefit structural hole of market networks to start their businesses.(4)The embedding order of these two structural holes will change depending on the differences in the local resource endowment.This article proposes some suggestions to encourage professional farmers to develop featured agricultural projects,build a close benefit-linked mechanism with smallholders through the provision of socialized services,and participate in the governance of rural communities.

Improved reproducing kernel particle method for piezoelectric materials

引用

Chinese Physics B 2018年第1期27卷 215-222页

作者：马吉超魏高峰刘丹丹 School of Mechanical and Automotive Engineering Qilu University of Technology college of foreign languages Shandong Normal University

In this paper, the normal derivative of the radial basis function （RBF） is introduced into the reproducing kernel particle method （RKPM）, and the improved reproducing kernel particle method （IRKPM） is proposed. The method can decrease the errors on the boundary and improve the accuracy and stability of the algorithm. The proposed method is applied to the numerical simulation of piezoelectric materials and the corresponding governing equations are derived. The numerical results show that the IRKPM is more stable and accurate than the RKPM.

A Cognitive Interpretation of Synaesthesia

引用

学术界 2013年第2期 254-261页

作者： Liu Yan foreign languages Department Loudi vocational & Technical college Loudi Hunan 417000

Synaesthesia is a sensual feeling moved from one sense to another,it is a kind of rhetorical means as well as a cognitive device.According to Conceptual Blending Theory,synaesthesia is a set of mappings between different sensory organs,whose meaning construction process is a dynamic conceptual blending process,in which two or more sensory organs constitute different input mental spaces.In the blending process,different input spaces map between each other,and elements in inputs are selectively projected onto the blended space,which has its own emergent structure.Then,through composition,completion and elaboration,the blended space develops its own emergent content which is different from that of the inputs,thus producing new meaning.The in-depth study of the dynamic meaning construction process of synaesthesia based on the conceptual blending theory gives a strong explanatory force to synaesthesia and helps people to make better use of synaesthesia to express their thoughts and feelings.

Cognitive Interpretation of the Polysemy of Head in Terms of Metaphor

引用

学术界 2013年第8期 298-305页

作者： Deng Haiyan foreign languages Department Loudi vocational and Technical college Loudi Hunan 417000

Polysemy,one of the most important and pervasive semantic phenomenon across languages,is the word having many meanings by means of human cognition from a central meaning or basic meaning to the other extended meanings. Metaphor is a cognitive process and it is a mapping across different domains in nature rather than a simple linguistic phenomenon. The transference of different domains produces different contexts in which the phenomenon of polysemy appears. Therefore,this paper aims at interpreting the polysemy of head in terms of metaphor,finding out the relations between the various meanings of its polysemant and thus analyzing the cognitive motivation of polysemy. That will let people not only have a further understanding of polysemy,but also contribute to English vocabulary teaching.
