Authors:   Carey Business School, Johns Hopkins University, District of Columbia, 20001, Washington, United States of America, Li Tianyu
Published: January 2025

The core of financial institutions’ big data lies in risk control, making network security threat identification essential for enhancing data processing and service levels. This study applies the principles of network information transmission security prevention, combining frequency domain analysis and distributed processing to extract threat characteristics. A financial network security threat identification model is developed using BiGRU and Transformer models, and a SQLIA defense system is constructed by integrating multi-variant execution and SQL injection attack prevention. Additionally, an intelligent network security defense strategy is formulated based on finite rationality theory. Simulation results show an F1 composite score of 90.78% for threat identification, and the STRIPS-BR defense strategy reduces relative risk by 74.81% during peak times compared to other strategies. Supported by big data, this system ensures secure data transmission and enhances the network service capabilities of financial institutions.

Authors:   University of New South Wales, Beaconsfield, 2015, NSW, Australia, Ning Yangning
Published: January 2025

This paper examines how digital entertainment consumption drives China’s economic growth from multiple dimensions. Using panel data from 260 prefecture-level cities (2020–2022) and a multi-temporal double-difference method, the study finds that digital entertainment consumption significantly promotes economic growth, with a direct effect coefficient of 0.748. Robustness tests via the PSM-DID method confirm this effect, with a coefficient of 0.714, significant at the 5% level. In the low digital divide group, the regression coefficient is 6.325, while it is significantly lower in the high digital divide group, indicating that the digital divide weakens the effect. Heterogeneity analysis shows that enhancing consumer experience, generating new businesses, and boosting cultural influence positively impact growth. The findings provide insights for the sustainable development of the entertainment industry and the digital economy.

With the increasing penetration of distributed intermittent energy into distribution networks, the self-healing problem of distribution networks faces significant challenges. The load level and demand response must be considered as critical factors affecting fault recovery. This paper proposes a fault recovery strategy that combines islanding division and network reconstruction. First, a distribution network model with a distributed energy storage system is established. To optimize the use of distributed energy resources, controllable loads that can respond to demand are prioritized, and high-priority loads are included in the islanded network after a fault. Based on the islanding division results, the remaining non-faulty power loss areas are restored through main network reconstruction. The improved whale optimization algorithm is employed to solve the problem. Simulation results demonstrate that load demand response is closely linked to the islanding process, and an optimal fault recovery strategy can be achieved by utilizing the distributed energy storage system and the main network.

This paper aims to enhance the moral and vocational qualities of college students by integrating moral education elements into career planning education. The BOPPPS teaching model is constructed, comprising six modules: introduction, objectives, pre-test, participatory learning, post-test, and summary, to effectively stimulate students’ interest and initiative. Moral education elements are integrated into career planning education through an intelligent teaching platform, incorporation into teaching processes, and the use of the second classroom to promote in-class and out-of-class linkages. Additionally, a fuzzy classroom teaching evaluation system is developed to assess the effectiveness of career planning education. The results indicate high reliability and validity of the evaluation system, with an alpha coefficient exceeding 0.8, a KMO value of 0.938, and a Bartlett’s test P-value of 0.000. Students’ positive classroom mood improved significantly from 35.79% to 68.42%, alongside an enhanced evaluation of classroom learning. The findings demonstrate the practical value of this approach in advancing education reform.

We consider the generating function for increasingly labelled trees. By generalizing the proof through symbolic method, we are able to study various statistics regarding binary increasing trees with respect to height restrictions. We then apply our approach to special colorings of increasing trees in order to obtain their generating functions and, from there, derive the counting sequence for (ak+a)-colored recursive trees. We also present some interesting bijections between colored and non-colored increasing trees.

With the rapid urbanization and expansion of subway rail transit, the subway has become an essential mode of public transportation. This study explores the impact of subway car color design on passengers’ psychological responses. Utilizing computer vision technology and a pruning algorithm, a target detection model for passenger expression recognition was developed, serving as an intuitive measure of psychological reactions. An optimized expression feature extraction network was constructed for facial expression recognition, while a multidimensional data analysis model, based on data mining, provided comprehensive insights. The study reveals that green, red, and yellow lighting evoke positive psychological responses, whereas blue and purple induce calmer or more somber reactions. These findings offer valuable guidance for urban subway carriage color lighting design, enhancing passenger experience.

Let \(\mathcal{F}\) be a family of graphs, and \(H\) a ``host'' graph. A spanning subgraph \(G\) of \(H\) is called \(\mathcal{F}\)- saturated in \(H\) if \(G\) contains no member of \(\mathcal{F}\) as a subgraph, but \(G+e\) contains a member of \(\mathcal{F}\) for any edge \(e\in E(H) - E(G)\). We let \(Sat(H,\mathcal{F})\) be the minimum number of edges in any graph \(G\) which is \(\mathcal{F}\)-saturated in \(H\), where \(Sat(H,\mathcal{F}) = |E(H)|\) if \(H\) contains no member of \(\mathcal{F}\) as a subgraph. Let \(P_{m}^{r}\) be the \(r\)-dimensional grid, with entries in each coordinate taken from \(\{1,2,\cdots , m\}\), and \(K_{t}\) the complete graph on \(t\) vertices. Also let \(S(F)\) be the family of all subdivisions of a graph \(F\). There has been substantial previous work on extremal questions involving subdivisions of graphs, involving both \(Sat(K_{n},S(F))\) and the Turan function \(ex(K_{n},S(F))\), for \(F = K_{t}\) or \(F\) a complete bipartite graph. In this paper we study \(Sat(H, S(F))\) for the host graph \(H = P_{m}^{r}\), and \(F = K_{4}\), motivated by previous work on \(Sat(K_{n}, S(K_{t}))\). Our main results are the following; 1) If at least one of \(m\) or \(n\) is odd with \(m\geq 5\) and \(n\geq 5\), then \(Sat(P_{m}\times P_{n}, S(K_{4})) = mn + 1.\) 2) For \(m\) even and \(m\geq 4\), we have \(m^{3} + 1 \le Sat(P_{m}^{3}, S(K_{4}))\le m^{3} + 2.\) 3) For \( r\geq 3\) with \(m\) even and \(m\geq 4\), we have \(Sat(P_{m}^{r}, S(K_{4})) \le m^{r} + 2^{r-1} - 2\).

En el ámbito académico existe una importante colección de compendios sobre metodología de la investigación desde diferentes perspectivas, áreas de conocimiento y fundamentos teóricos. En esa amplia colección descubrimos manuales con el objetivo de obtener respuestas rápidas y procesos lineales que poco contribuyen a la formación de los estudiantes en investigación. En el otro extremo, encontramos volúmenes cuya complejidad pocas veces se adapta a las necesidades de investigación y análisis. El apartado metodológico en una investigación es parte fundamental del proceso, ya que sienta las bases sobre las cuales se traza la ruta para comprender y responder a las interrogantes que buscamos conocer. Es una especie de brújula con la cual podremos calcular la orientación y el rumbo para llegar a nuestro destino.
En este escenario de diversidad es posible considerar que un volumen nuevo sobre el tema será infructuoso. No es el caso de esta propuesta editorial; su aportación se enmarca en una obra cuyo elemento central es la construcción de instrumentos para la recolección de información y datos en las ciencias administrativas. Una tarea necesaria, ya que su contribución en la atención de problemas desde las áreas administrativas y de gestión es sumamente valiosa. La inclusión de ejemplos y esquemas de fácil comprensión para la elaboración de indicadores y variables en diversas investigaciones de corte cuantitativo permitirá a los interesados contar con elementos novedosos para la recolección de datos y su posterior análisis.
Vale aquí enfatizar la necesidad de pensar al administrador como un investigador en ciernes, más allá de su papel inherente como gestor. Debe ser capaz de explicar la naturaleza de los fenómenos administrativos, to-mando en consideración el proceso científico, desarrollando soluciones de forma creativa. Además, debe adquirir la habilidad para transmitir ideas y transformar el entorno de su competencia. No son simples aspiraciones, sino objetivos que deben ser planteados en su formación académica. Este compendio es una muestra de cómo pueden lograrse los objetivos antes expuestos, ya que permite visualizar los resultados de investigaciones actuales a través de la colaboración entre profesores y estudiantes de la Universidad Autónoma de Baja California, quienes lograron crear un ejemplar de calidad académica y suma utilidad práctica.

Epistemology of Hadith about AL-Mahdi: Analytical Study of the Book "Is Imam Mahdi's Discourse Real?"
Authors: Solihin Muhtar , Fakhrurrozi Furkony Fadhli , . Rohanda
Published: January 2025

Epistemology is a part of the Philosophy of Science which is tasked with discussing the sources, validity and authenticity of science. If applied in Hadith Science, epistemology can be used as a way to find out and obtain narrative sources of hadith texts about al-Mahdi, which is the focus of this research. For this reason, this research aims to explore the source, validity and authenticity of al-Mahdi's hadith. This type of research is qualitative with descriptive analysis of library objects. The main source in this research is Dadi Herdiansah's written work entitled Discourse of Imam Mahdi Realitakah?, a book that is widely read by people in Indonesia. The data collection technique used was direct observation of the book accompanied by a study of supporting literature. The research results found that hadith epistemology can be applied in studying hadith texts about al-Mahdi. In the hadiths about al-Mahdi contained in the book, it was found that there were six lines of sanad (links connecting to the text of the hadith) collected by six narrators or rawi (people who transferred or narrated hadiths to others) from among the friends of the Prophet, who indicated marfu' (relying on the Prophet) and mentioned the word "al-Mahdi" in the sentence text (matan) in the hadith. Then, in order to achieve the validity of the authenticity of the hadith, the author of the book used “a coherent theory” which then discovered that there were several hadith transmitters whose position was weak (dho'if) who contradicted other transmitters who were stronger so that the hadith that went through the weak transmission route became rejected.

Published: January 2025

CQDs, characteristically quasispheroidal carbon nanoparticles composed of amorphous to crystalline carbon base,  are a prospective semiconductor quantum dots owing to its excellent optical absorptivity, chemical stability, nontoxicity, and facile synthesis. In this study, we demonstrated the impregnation method to integrate CQDs, formed from chitosan with UiO-66 from terephthalic acid recycled by waste PET to synthesize CQDs@UiO-66 nanocomposite. After the hybridization of CQDs with UiO-66, the low band gap energy of the CQDs@UiO-66 sample was determined at 2.4 eV, allowed the demonstration of photocatalytic activity under high visible light. This material was tested in the photodegradation of RR-195 dye and compared with the pristine components. The highest RR-195 degradation efficiency recorded when using the catalyst mass of 50 mg, dye concentration of 70 ppm after 4 h under visible light irradiation was 96% and the result rather maintained its performance (86,4%) after four cycles. These results could promote a new material circularity pathway to develop new semiconductors that can be used to protect water from further pollution.

Published: January 2025

In this study, the ternary composite ZnO/g-C3N4/seed stem biochar (ZCNBC) was successfully synthesized using a simple hydrolysis method. Research shows that biochar has a significant influence on the structure and photocatalytic activity of the resulting composite materials. It has shown a series of roles such as inhibiting crystal growth, improving specific surface area, narrowing the band gap, and enhancing visible light absorption of ZnO. The resulting photocatalytic composite was used as an effective photocatalyst for the photodegradation of the antibiotic doxycycline (DC) from aqueous solution. The prepared ZCNBC hybrid catalyst was shown to have much higher photocatalytic activity than pure ZnO in the decomposition of DC (10.4 times higher). All synthesized catalysts exhibited extremely high photocatalytic efficiency under visible light; The DC photocatalytic degradation efficiency of ZCNBC can reach 98.1% under visible light. The results show that the prepared catalysts are promising for the degradation of DC from water sources.

In PEMFC fuel cells, the catalyst layer plays a crucial role, significantly influencing the characteristics of the fuel cell. Various methods for fabricating this catalyst layer, such as brushing, decanting, and spraying, are employed. In this report, the method of fabricating the catalyst layer by directly spraying the catalyst onto the gas diffusion layer with an ultrasonic spraying device is implemented. The impact of some spraying parameters, such as solvent ratio and spraying rate, on the electrochemical activity of the catalyst layer is investigated. The electrochemical properties are evaluated using techniques such as LSV and CV. The uniformity and surface morphology of the catalyst layer are assessed using optical microscopy. The electrical properties of the catalyst layer are assessed through the employment of I-V curve measurements. The results are discussed and indicate that the spraying mode gives a high-quality catalyst layer at a solvent dilution ratio of 60% of the initial catalytic ink solution and a spraying rate of 1.5 ml/min. And this mode is applied to fabricate the catalytic layer for PEMFC fuel cells.

Copper ion pollution from various industries is a major concern due to its detrimental impact on water quality. This study investigated the potential of ETS-10 zeolite, synthesized hydrothermally at 230°C for 24 hours, as an adsorbent for Cu(II) removal from aqueous solutions. Characterization of the synthesized ETS-10 was performed using XRD, FT-IR, and SEM-EDX techniques. The effects of pH and contact time on Cu(II) adsorption efficiency were evaluated. The concentration of Cu (II) ions before and after adsoption was recorded by the atomic absorption spectrophotometry technique (AAS). The results revealed that pH plays a critical role, with optimal adsorption observed at pH 6 and a contact time of 540 min. The Langmuir isotherm model indicated a maximum adsorption capacity of 115.02 mg/g, suggesting that ETS-10 has promising potential as a "super adsorbent" material for copper ion removal in water treatment applications.

Metal-organic framework materials based on cobalt(II) ions and       1,3,5-Benzenetricarboxylic acid were synthesized by microwave and hydrothermal methods. The time to synthesize materials by hydrothermal method is much longer than by that of the microwave method. Synthesized materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR), and Brunauer-Emmett-Teller (BET) surface area. The results showed that the morphology of the Co-BTC is a rod-shaped crystal with length between 5-10 μm. The specific surface area of the material synthesized by microwave and hydrothermal methods is 99.085 m2/g and 45.348 m2/g, respectively.

Water electrolysis using proton exchange (PEMWE) is an effective method for hydrogen production without CO2 emission. The most important part in a PEMWE is the bipolar plates (BPPs). They are multifunctional components, ensuring the supply of water and removal of gases in each individual cell and facilitating charge carrier transport between them. The BPPs need to be maintained in the harsh PEMWE-operating environment with low costs and high electrical conductivity. Excellent corrosion resistance is found in Ti and the metal is therefore considered to be the best candidate for BPPs in PEMWE today. However, under the harsh conditions of PEMWE, the titanium material is degraded: brittle, craced and forms a passive oxide layer on the surface, and increasing the ohmic resistance. To overcome this, a thin oxide layer of mixed metallic oxides including IrO2 and RuO2 has been considered intensively for coating on the surface of the titanium. In this report, a thin film of IrxRu(1-x)O2 is applied over titanium by thermal decomposition. The XRD, SEM, cyclic voltammetry (CV), anodic polarization, chronoamperometry are employed to determine the physical characteristics and the electrochemical properties of material in 0.5 M H2SO4 solution. Based on testing results, the thin film of Ir5Ru5O2 coated bipolar plate having high durability and electric conductivity to serve as BPPs in PEMWE.

In this study, we synthesized TiO2 nanoparticles from titanium slag, and 1,3,5-copper benzene tricarboxylate (MOF-199), MOF-199/TiO2 composites using the microwave method. The synthesized materials were characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy-energy (SEM), Brunauer–Emmett–Teller (BET) surface area using N2 adsorption/desorption isotherm methods, and UV–Vis diffusive reflectance spectra. MOF-199 exhibited octahedra morphology and showed a surface area of 1059.366 m2/g. The photocatalytic activity of the obtained materials was examined for Rhodamine B (RhB) degradation under visible light irradiation. The results showed that MOF-199/TiO2 had higher photocatalytic activity under visible light than both TiO2 and MOF-199.

The analytical characterization of pyrolysis bio-oil represents a formidable challenge, attributed to its complex composition and inherent corrosive properties. Addressing this, we introduce an improved version of Effective Carbon Number (ECN) model, a novel predictive framework designed to accurately estimate the Flame Ionization Detector (FID) response factors of oxygenated compounds within bio-oil based solely on their molecular structures. The ECN model, underpinned by an analysis of over 150 compounds, leverages the structural attributes of molecules to ascertain their respective response factors, thereby facilitating precise concentration measurements. Central to our findings is the model’s ability to correlate FID detector responses directly with two critical parameters: the total number of carbon atoms within the molecule, and the degree of oxidation of each carbon atom. Additionally, we have compiled a comprehensive table delineating response factors across various oxygenated functionalities, a resource that significantly expedites the analysis process of complex bio-oil mixtures.

A Thermal Energy Storage Bamboo Plastic Composite (TESBP) was developed using bamboo,polyethylene glycol (PEG) and epoxy. The material exhibited a transmittance of 42% and 63%, indicating effective pigment processing. Fourier Transform Infrared Spectroscopy (FTIR) analysis revealed the removal of chromophore groups from the original bamboo structure, stabilize with intercalated polymers. Scanning Electron Microscopy (SEM) showed tight integration of the phase change material within the wood matrix. Thermogravimetric analysis results show that the composites of TB/epoxy and TB/PEG samples began to decompose at 325°C and 329°C, respectively. The phase transition thermal properties, evaluated through differential scanning calorimetry (DSC), revealed that the melting and solidification enthalpies were 160.2 J/g and 147.6 J/g, respectively. These characteristics highlight TESBP's potential for medium temperature range thermal energy storage, presenting a viable composite material for such applications.

The Libyan economy is a rentier economy dominated by oil output as the main source of GDP, which undoubtedly represents a fundamental and pivotal flaw in this economy, making it more volatile and less capable of achieving economic stability due to the oil sector's lack of adherence to internal economic control. From this perspective, the study aimed to measure the contribution of both the manufacturing and agricultural sectors, in addition to tax revenues, and to identify the strength and direction of the impact of these outputs on the Libyan GDP. To achieve this goal, the researchers relied on the inductive approach and the standard method, which, after conducting stability tests, indicated that the optimal methodology is the autoregressive distributed lag model. The results indicated a statistically significant positive impact of both agricultural and industrial outputs on the dependent variable represented by gross national output, with their elasticity being (0.66 and 0.34) respectively, while the impact of tax revenues was negative and significant, with its elasticity estimated at about (0.41). One of the main recommendations of the study is the necessity to adopt plans and programs for the development and integration of the industrial and agricultural sectors to achieve higher contribution rates to the formation of GDP.
Keywords: GDP, industrial output, agricultural output, tax revenues, Libyan economy.
