Authors: Ji Gaoyun 
Published: March 2024

The expansion of enrollment in universities has led to a decline in the overall quality of students in higher vocational colleges. The application of Internet technology in the field of education has also accelerated the speed of knowledge updating and iteration, which requires students to have the autonomous learning ability in order to adapt to the rapid development needs of society. In the context of the Internet, utilizing online resources for autonomous learning and lifelong learning is an important way for students to grow and succeed. Independently design survey questionnaires and interviews to conduct surveys or interviews on current freshmen and sophomore higher vocational students and teachers. Collect and organize first-hand materials on higher vocational students' willingness, methods, content, effects, and other aspects of autonomous learning. The analysis results indicate that higher vocational students have problems such as weak awareness of autonomous learning, vague goals, lack of cognition, insufficient identification ability, and lack of effective resources.
Evaluating the Successful Factors of Arknights as a Mobile Gacha Game with GameFlow
Authors: Zhang Haodong 
Published: March 2024

GameFlow is a widely used model of player enjoyment, with numerous applications to game designation and evaluation. Derived from a general set of heuristics for creating enjoyable player experiences, GameFlow has already become a general model of player enjoyment,suitable for all kinds of game genres and platforms. However, research so far has been focused on traditional mobile games while gacha game has not received enough attention. Arknights is a famous gacha games released in 2020 worldwide. This study evaluates how Arknights grows into one of the most successful mobile gacha games and IP in recent years,using the GameFlow model as a conceptual foundation. One reason is that designers of Arknights are good at dealing with the balance between game challenges and increasing players’ skills. In other words, the complexity management of Arknights is pretty good. Another one is that players can get high concentration and immersion due to Arknights’ excellent auditory and visual experience. The two advantages behind the success of Arknights are worth studying for global mobile game industry.

Published: March 2024

Cyclic steam injection is widely applied in the development of heavy oil reservoirs. However, as reservoir development continues, steam channeling phenomena become increasingly severe, Serious impact on development effectiveness. Slug combinations of gel and foam is more effective than using gel and foam alone for steam channeling control. In this study, taking a steam channeling well in the A oilfield as an example, a numerical simulation model is established using CMG software. Based on this model, the effects of foaming agent concentration, foaming agent injection rate, gel injection timing, and nitrogen injection quantity on the development performance in the gel foam slug steam channeling plugging system are investigated. The research results indicate that higher foaming agent concentration, faster injection rate, and earlier gel injection timing lead to increased oil production. The nitrogen injection quantity exhibits an optimal value. Comparing the performance of gel foam slug system assisted cyclic steam injection with steam huff and puff alone, the results show that the gel foam slug system assisted cyclic steam injection achieves an incremental oil production of 9104 m3 over four cycles, as compared to steam huff and puff alone.

Published: March 2024

Periodontitis is a chronic inflammation of periodontal support tissue caused by local factors. Eucommia ulmoides, a traditional Chinese medicinal herb, has a significant therapeutic effect on periodontitis, but its mechanism of action is still unclear. In this study network pharmacology method was used to deeply elucidate the pharmacological substance basis and mechanism of Eucommia ulmoides in treating periodontitis. The protein interaction network (PPI) was constructed using the STRING database. The GO and KEGG signal pathway enrichment analyses of the intersected targets were performed using the DAVID database to predict the mechanism of action. The results indicate that Eucommia ulmoides exerted its therapeutic effect on periodontitis through a synergistic mechanism of multiple components, targets, and pathways. The top 8 therapeutic targets were identified, including EGFR, HIF1A, MMP9, ESR1, JUN, PPARG, AKT1, and SRC. Prolactin and HIF-1 signaling pathway may be the key mechanism of Eucommia ulmoides in treating periodontitis.

Authors: Dong Lihua , Liu Ying 
Published: March 2024

In order to verify the oxidation of silicon to silicon dioxide during the calcination process of silica containing dust, silicon powder and monocrystalline silicon were calcined at different temperatures. The sample was analyzed using Fourier transform infrared spectroscopy (FTIR) and compared with the FTIR spectrum of the silica standard. The results show that the antisymmetrical stretching vibration, symmetrical stretching vibration and bending vibration absorption peak of Si-O-Si were obviously in the FTIR spectra of silicon powder and monocrystalline silicon calcined at 750oC. The positions of those absorption peaks correlate broadly with the absorption peaks of standard silica. It is concluded that when the calcination temperature was above 750oC, elemental silicon would be oxidized to silica at different levels, which would cause a higher silica content detected in dust.

Solving a Class of Nonsmooth Nonconvex Optimization Problems Via Proximal Alternating Linearization Scheme with Inexact Information
Authors: Huang Ming , He Yue , Qiao Pingping , Zhang Siqi , Feng Yongxiu 
Published: March 2024

For optimization problems minimizing the sum of two nonconvex and nonsmooth functions, we propose an alternate linearization method with inexact data. In many practical optimization applications, only the inexact information of the function can be obtained. The core idea of this method is to add a quadratic function term to the nonconvex function(called local convexification of nonconvex function), and then to construct an approximate proximal point model. In each iteration, a series of iteration points are obtained by solving subproblems alternately. It can be proved that, in the sense of inexact oracles, these iteration points converge to the stable point of the original problem, and theoretically show that the algorithm has good convergent properties.

Published: March 2024

In order to explore the influence of different storage conditions on the physical properties of cut tobacco during storage, this study measured the changes in moisture content, moisture activity, and physical properties of cut tobacco. Based on these indicators, the relationship between various physical properties was investigated. The selected storage conditions were a temperature of 23-25℃, humidity of 55%-65%, and storage time of 3-25 h. The results showed that maintaining the appropriate moisture content of 60% and a storage temperature of 25℃ was beneficial for preserving the physical properties of cut tobacco. Among the storage conditions, humidity had the most significant impact on the physical properties of cut tobacco, followed by temperature. Within the limited time range, the storage time had a relatively less noticeable effect on the quality of cut tobacco.

Published: March 2024

In the industrial practice of spent lithium-ion battery recycling, mechanical separation, pyrometallurgy and chemical dissolution technologies are often used to achieve the separation and recovery of cathode materials, but there are problems such as low material dissociation rate, low recovery rate, high energy consumption, serious lithium loss, and impurity ion embedding. In this paper, supercritical CO2 fluid was used to strengthen the separation of the cathode active material from the aluminum foil in the spent lithium-ion battery to achieve direct and efficient recovery of the active substance. The analysis of charge and discharge, AC impedance and differential capacitance curves show that the electrode of supercritical recovered material has higher ion diffusion coefficient and better redox reversibility, so it has higher charge and discharge capacity and better cycle stability than the traditional high-temperature calcined recovered material.
