Picosecond versus femtosecond-laser ablation of silicon in atmosphere
Authors: Gross Jason M. , Shavandi Seyedeh Reyhaneh , Zagorac Teodora , Pasterski Michael J. , Hanley Luke
Published: October 2023

Laser ablation (LA) using nanosecond (ns) or femtosecond (fs) pulse widths is well-established for the volatilization of a liquid or solid for applications ranging from micromachining to sampling for compositional analysis. Far less work has examined laser ablation in the intermediate picosecond regime (ps-LA), which corresponds to the approximate timescale for the transfer of energy from laser-excited electrons to the lattice. 213 and 355 nm ps-LA of silicon (Si) with Gaussian beam profiles is compared here to 800 nm fs-LA with both Gaussian and flat-top beam profiles, all performed at or above the ablation threshold with 20 000–67 000 laser pulses. The morphology and composition of the ablation spots are examined using scanning electron microscopy and energy dispersive x-ray spectroscopy (EDS), respectively. 213 nm ps-LA yields more visible nanostructures compared to those ablated by 355 nm ps-LA, but both form central craters with surrounding nanostructures due to resolidified material. The flat-top fs beam creates protruding nanostructures isolated near the rim of the crater and an inside-out umbrella-like structure at the center. The Gaussian fs-LA region displays a relatively smooth conical crater, albeit with some nanostructure at the rim of the crater. EDS finds that these nanostructures are at least partly composed of silicon oxide or suboxides. The invisibility of these nanostructures to optical profilometry is consistent with black-silicon. The ablation crater results from optical profilometry for 213 nm ps-LA are close to those for 800 nm flat-top fs-LA, and both are consistent with cylindrical craters.

Authors: Viana Lilian Carolina , França da Cunha Christiano
Published: October 2023

Objetivo: Mapear os estudos sobre as plataformas Peer-to-Peer (P2P), apresentando considerações importantes em uma agenda para pesquisas futuras.
Originalidade/Valor: Existe grande interesse em entender melhor as plataformas baseadas na interação entre pessoas, pois muitas são apontadas como ecológicas, democráticas e com preços menores (Wirtz et al., 2019). Contudo, há uma lacuna quanto a uma sistematização das publicações que tratam do modelo de negócios das plataformas P2P, no contexto amplo da economia compartilhada, uma vez que os estudos se encontram fragmentados.
Métodos: Foi adotada a Systematic Literature Network Analysis (SLNA) que combina a Revisão Sistemática da Literatura com Análise de Rede de Citações (Colicchia & Strozzi, 2012). Para a revisão sistemática foi enfatizado os critérios de pesquisa, e na análise de redes foi utilizado o software VOSviewer®.
Resultados: Mediante as redes construídas e suas conexões, foi proposta uma agenda com quatro direções futuras: i) efeitos do compartilhamento pelas plataformas P2P; ii) estrutura de mercado das plataformas P2P; iii) o setor de acomodação P2P; e, iv) temas emergentes.
Conclusões: A pesquisa foi além da descrição e se aprofundou direcionando temáticas de pesquisa. Foi possível contribuir com o estímulo da investigação e discussão no campo teórico e prático, uma vez que, para Chen et al. (2020) as plataformas digitais continuam a florescer no mundo dos negócios.

The Likelihood of Financial Reporting Fraud: Does the Gender of CEO, CFO, Board of Commissioners, and Audit Committee Matter?
Authors: Julianti Intan Kurnida , Fuad Fuad
Published: October 2023

The purpose of this study is to examine whether the presence of women in executive positions such as CEO, CFO, board of commissioners, and audit committee can reduce the occurrence of financial statement fraud. The sample was selected from manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2013 to 2022. The results of this study show that female CFOs and audit committees have a negative and significant influence. This indicates that the presence of women in the CFO position and the audit committee can reduce the occurrence of financial statement fraud in companies. This study offers a different perspective on the two-tier system of corporate governance in a developing country, namely Indonesia, about the impact of female CEO, CFO, board of commissioners, and audit committee on the occurrence of financial statement fraud. The practical implications of this research are first, the importance of promoting gender diversity of executives as a corporate governance mechanism. Second, it can provide recommendations or requirements for gender diversity as part of corporate governance mechanisms to create gender equality.

Research on the optimization of the innovation path of university education and teaching management based on the weighted function algorithm of RFID technology
Authors: Wu Kun
Published: October 2023

College education and teaching management are experiencing a transition from traditional modes to informational modes. This paper constructs a management mode for university teaching informatization based on RFID technology and designs the workflow and functions for RFID. For the positioning of student RFID tags on campus, a time-gap ALOHA algorithm is proposed to reduce the collision rate by dividing the processing time of student tags into several time gaps. After obtaining the student tags, an improved K-weighted center-of-mass localization algorithm is proposed for multi-point localization, which makes the weight of multiple known nodes in the process of operation more reasonably distributed through the setting of the weight size. In the simulation test of campus student localization, when the number of beacon nodes is 40, the average error of the K-weighted prime is 6.5%, 4.25%, and 2.1% lower than that of the prime algorithm, weighted prime, and weighted differential prime, respectively.

A Study of the Effectiveness of Corpus-Assisted Collocation Teaching on Improving College Students’ English Writing Ability Based on Random Matrix Theory
Authors: Lin Xuqin
Published: October 2023

This paper presents a semantic analysis of corpus-assisted collocation teaching based on the random matrix theory, taking into account the characteristics of the computer corpus. The construction of a word-document matrix is based on the potential semantic analysis of the corpus and the intrinsic relationships between words and documents. The aggregation and combination relations of collocation, i.e., the lexicon of word meanings, are used to calculate affirmative sentence similarity, incorporating dependent syntactic and semantic analysis. The error analysis method was applied to the teaching of collocations to analyze the common types of errors and the variability of writing errors in English writing and to discuss the correlation between the performance of English composition and the number of collocations used. The correlation coefficient between composition scores and the number of collocations in compositions was 0.924, and the composition scores of college students had a positive linear relationship with the number of collocations.

Authors: Li Lanqing , He Bin , Xie Yuxing , Huang Jiahui , Zhou Xizheng
Published: October 2023

This study employs An evolutionary algorithm to set up a multilayer BP neural network. The goal is to solve the issue that BP neural systems converge slowly and readily fall into local optimal solutions. The genetic algorithm reaches an initial set of evolutionary generations and outputs a BP neural network’s most appropriate starting weights and thresholds. In the GA-BP model, the fitness value is calculated as the sum of the total errors between the network’s output and the desired output. A communication protocol device was used to gather performance information for the global solar PV/T system, and the GA-BP neural network model parameters were adjusted. The GA-BP model had a mean absolute error of 0.7% lower than the BP model’s for the forecast of electrical efficiency. The GA-BP model has an average relative error of 0.21 in forecasting heating power.

In this paper, an impact degree indicator system with several indicators is established, and the stability, estimation, lag selection and forecasting of the VAR model are considered in the model construction, and the MVAR model structure and estimation methods are also studied. Chongqing city is selected as the object for the actual case, and the influence degree of international logistics factors on international trade is explored, and the influence of transportation costs on real trade is studied in depth from two aspects: the spatial and temporal dimensions and the influence of high logistics costs on the trade of CIS countries. The study results show that: high logistics costs lead to the concentration of international trade in Central Asian countries up to 0.4 to 0.5. More than half of the goods the six CIS countries sell to the EU are concentrated on one or two specific items. The impact of international logistics costs is so significant that it cannot be ignored in international trade.

A study on the evolutionary model of legal disputes based on fractal theory
Authors: Hu Jing
Published: October 2023

In this paper, a legal dispute mediation game model is constructed based on fractal theory, characterized by self-similarity properties in disputes. Secondly, the legal dispute evolution game model is constructed, the dynamic differential equation of frequency or frequency is used, and an adaptive degree dispute evolution stabilization strategy (ESS) is proposed according to the evolution principle. Finally, the simulation and analysis of the dispute evolution game model are carried out with the medical-patient dispute as an example. The results show that when D<0 takes the values of −4 and -2, both sides of the doctor-patient dispute will rapidly move toward the norm and form a benign evolutionary trend. When D>0 takes the values of 2 and 4, the two sides of the doctor-patient dispute will rapidly gather toward the challenge and form a vicious evolutionary trend. The study of this paper helps to understand the evolutionary process of legal disputes better and provides a reference for resolving disputes.

Authors: Yan Honglin
Published: October 2023

In this paper, firstly, the core literacy and teaching mechanism of the synergistic development of vocational education and open education is studied based on the school education plan under the requirement of the new engineering education goal to improve the quality of vocational school education. Then, the mechanism of collaborative development of vocational education and open education based on multi-scale integration characteristics is studied, and the teaching correction multi-scale integration network in the collaborative model of vocational education and open education is proposed according to the students’ learning state in the classroom. To avoid the problem of over-fitting the loss function in the prediction of the learning state, it is necessary to introduce the regular term to prevent the model from over-fitting and to analyze the learning state and the satisfaction of the collaborative model analysis. The results showed that the learning status of the two students was in a state of concentration, which was a more objective analysis of the distribution of students’ attention in the classroom. In terms of satisfaction with the collaborative model, the satisfaction level of the first-year students with the factors of the collaborative model of vocational education and open education was lower than that of the second-year and third-year students. This study is important for achieving the ambitious goal of achieving high-quality development of the synergistic mechanism between vocational education and open education.

Authors: Li Meng , Liang Qiu
Published: October 2023

This paper focuses on analyzing and studying digital capitalism using a textual analysis model in the context of Marxist political economy. The magnitude of the angle between text vectors can be used to measure the similarity between digital capitalism and political economy. An iterative computational approach is employed to address the issue of overfitting in text. Constructing a BERT model involves formulating a self-attentive mechanism and setting up an embedding layer. The direction of digital capitalism’s ideology in the political economy context is examined about its characteristics. The results show that digital labor is more secretive regarding office location than traditional labor, with a secrecy rate of 60%. Unpaidness, large quantity, and potential value dominate data characteristics, with 90% unpaid data.

Published: October 2023

This paper focuses on the correlation analysis of the thinking operation model, learning motivation, and ideological and political education practices. According to the correlation between the thinking operation model and learning motivation, internal motivation and external motivation are analyzed for motivation to learn. The core elements of the ideological and political education practice system in colleges and universities are finely classified, and students’ learning motivation and academic achievement are selected as the main research objects. A combination of stack autoencoder and Gaussian mixture model is used to constitute a deep clustering model of learning motivation for intervention analysis. The change in achievement was significant before and after the intervention twice, p<0.1, which means that the achievement after the intervention was significantly higher. Colleges and universities should mobilize students’ learning motivation to enhance the effectiveness of ideological and political education practices in colleges and universities.
