Abstract

The increasing frequency of seismic events poses significant challenges to the structural integrity of suspension bridges. Understanding how these structures respond to seismic loads is essential for ensuring their safety and performance. Effective modeling and simulation techniques can provide valuable insights into the behavior of suspension bridges under such conditions. This study aims to develop a simulation model for suspension bridges to assess their performance under seismic loading. The research seeks to identify critical factors influencing the bridge's response and propose design modifications to enhance resilience against earthquakes. A finite element analysis (FEA) approach was employed to create a detailed simulation model of a suspension bridge. Various seismic scenarios were simulated using different ground motion records. Key parameters, including displacement, stress, and dynamic response, were monitored and analyzed to evaluate the bridge's behavior. The simulation results indicated that the suspension bridge exhibited significant displacement under seismic loads, particularly at the midspan. Stress concentrations were observed at critical joints and cables, highlighting potential failure points. Design modifications, such as increased cable tension and enhanced damping systems, were proposed to improve the bridge's seismic performance. The research concludes that simulation modeling is a valuable tool for understanding the seismic response of suspension bridges. The findings emphasize the importance of incorporating seismic considerations into the design process. Future research should focus on validating the simulation results with experimental data and exploring advanced materials and technologies to further enhance bridge resilience.

Abstract

The quality of elementary education is fundamentally linked to teacher effectiveness, with professional competence being a cornerstone of student success. This study aimed to quantitatively determine the relationship between the professional competencies of elementary school teachers and the achievement of Graduate Competency Standards (GCS) by their students. A quantitative correlational design was employed, involving a sample of certified teachers and their respective students from several elementary schools. Teacher professional competence was assessed using a standardized competency test, while student achievement data was obtained from official GCS scores. The data were analyzed using Pearson correlation. The results revealed a significant and strong positive correlation (r = 0.78, p < 0.01) between the level of teachers’ professional competence and students’ GCS achievement. Higher teacher competence scores were consistently associated with higher student achievement. This study concludes that teachers’ professional competence is a critical and significant predictor of students’ success in meeting educational benchmarks. Therefore, enhancing the quality of elementary education hinges on targeted and continuous professional development programs for teachers.

Abstract

Gifted children often exhibit asynchronous development, where cognitive, emotional, and social growth occur at uneven rates, creating complex psychological needs that are frequently misunderstood in educational and familial contexts. This developmental asynchrony may result in social-emotional vulnerabilities such as heightened sensitivity, perfectionism, and difficulties in peer relationships. The study aims to explore the psychological needs of gifted children with a focus on addressing the impact of asynchronous development on their social-emotional well-being. A qualitative research design employing phenomenological analysis was utilized to examine the lived experiences of 25 gifted students aged 8–14, selected from specialized education programs. Data were collected through in-depth interviews, behavioral observations, and teacher reflections, followed by thematic coding. The results revealed three major themes: (1) emotional intensity as both a strength and source of distress, (2) social incongruence and peer isolation resulting from developmental disparities, and (3) the need for adaptive counseling and differentiated emotional support. The study concludes that educational and psychological interventions must be tailored to the unique developmental trajectories of gifted children, emphasizing emotional regulation, self-concept development, and social integration. Understanding asynchronous growth is essential for fostering balanced psychological and academic development among gifted learners.

Abstract

Hybrid quantum systems that integrate solid-state qubits with superconducting circuits have emerged as a promising architecture for scalable quantum information processing. Achieving strong coherent coupling between distinct quantum subsystems, such as spin ensembles and microwave resonators, remains a critical challenge in realizing hybrid quantum technologies. This study aims to engineer and characterize a hybrid platform that couples nitrogen-vacancy (NV) centers in diamond with a superconducting coplanar waveguide resonator. A combination of cryogenic microwave spectroscopy and time-domain measurements was employed to evaluate coupling strength, coherence times, and collective spin photon interactions at millikelvin temperatures. The experimental results demonstrated a vacuum Rabi splitting of 22 MHz, confirming the realization of a strong coupling regime between the NV spin ensemble and the superconducting resonator. The coherence lifetime of the NV centers remained above 100 ?s under optimized magnetic field alignment, ensuring stable quantum-state transfer. The findings reveal that hybrid systems combining spin-based and superconducting components can serve as viable interfaces for quantum memory and quantum communication nodes. The study concludes that engineering such strong spin–photon coupling represents a foundational step toward the development of coherent, scalable hybrid quantum networks.

Abstract

Quantum coherence has been shown to play a crucial role in optimizing energy transfer in photosynthetic systems, especially in the Fenna-Matthews-Olson (FMO) complex, which is responsible for efficiently capturing light energy in photosynthetic bacteria. While quantum coherence is often considered fragile and short-lived in biological systems, recent studies have indicated its potential for sustaining long-lived coherence, facilitating highly efficient energy transfer. This research investigates the implications of long-lived quantum coherence in the FMO complex for energy transfer efficiency, exploring how coherence persistence enhances the system’s performance. The objective of this study is to analyze the effects of long-lived quantum coherence on energy transfer efficiency in the FMO complex under varying environmental conditions, such as temperature and bath coupling. The results demonstrate that long-lived quantum coherence directly correlates with higher energy transfer efficiency, with temperature and environmental factors playing a significant role in maintaining coherence. The study shows that the FMO complex utilizes quantum coherence as an active resource to optimize energy conversion, achieving efficiencies well beyond classical expectations. In conclusion, this research underscores the importance of quantum coherence in biological energy transfer processes and offers insights into bio-inspired quantum systems for efficient energy harvesting.

Abstract

The ability to think critically and creatively is essential for students to succeed in a rapidly changing world. Traditional teaching methods often fail to develop these skills in students. Inquiry-Based Learning (IBL), which encourages students to explore questions and seek solutions independently, is proposed as an effective approach to enhancing critical and creative thinking. Despite its potential, limited research exists on the impact of IBL on these skills in high school settings, particularly in non-Western educational contexts. This study aims to investigate the influence of Inquiry-Based Learning on high school students’ critical and creative thinking skills in a classroom setting. A quasi-experimental design was used, involving 120 high school students from two different schools. One group received IBL-based instruction, while the other group followed traditional teaching methods. Data were collected using pre- and post-assessments of critical and creative thinking skills, along with student surveys and classroom observations. The results revealed that students in the IBL group showed significant improvements in both critical and creative thinking skills compared to the control group. Analysis indicated that IBL encouraged greater student engagement, problem-solving, and innovative thinking. The study suggests that Inquiry-Based Learning is a promising method for enhancing high school students’ critical and creative thinking skills, offering valuable implications for educational practices.

Abstract

Dengue Fever remains a significant public health issue in Indonesia, with frequent outbreaks exacerbated by varying climatic conditions and human mobility. Understanding the dynamics of its transmission is critical to developing effective control strategies. This study aims to develop a mathematical model that incorporates climate variability and human mobility to assess the transmission dynamics of Dengue Fever in Indonesia. The model utilizes a compartmental framework, where the population is divided into susceptible, infected, and recovered individuals. The impact of climate factors such as temperature and rainfall, along with human mobility patterns, is integrated through differential equations. The study uses historical epidemiological data from the Indonesian Ministry of Health, alongside climate data from the Indonesian Meteorological Agency and human mobility data derived from mobile phone usage and transportation systems. Numerical simulations are conducted to predict the effects of climate variability and mobility on Dengue Fever outbreaks. Results indicate that both climate change and human mobility significantly influence the frequency and intensity of outbreaks, with certain regions being more vulnerable to epidemic peaks. The study concludes that incorporating environmental and social factors into epidemiological models can enhance the accuracy of Dengue Fever predictions and inform targeted intervention strategies.

Abstract

Cell-based therapies for myocardial infarction (MI) are critically limited by poor acute cell retention and viability following direct injection. The harsh, ischemic microenvironment and mechanical washout result in massive cell death, neutralizing therapeutic potential and leading to failed clinical translation. This research aimed to design, synthesize, and evaluate a novel, injectable, thermosensitive hydrogel as a “pro-survival” cell delivery vehicle. The objective was to determine if this biomaterial could solve the critical failure points of retention and viability, thereby enhancing the therapeutic efficacy of mesenchymal stem cells (MSCs) post-MI. A composite hydrogel (Poloxamer/Hyaluronic Acid) was characterized in vitro for its rheological properties (LCST), mechanical stiffness, and cytoprotective capacity under ischemic stress. Its in vivo efficacy was then evaluated in a rat MI model (LAD ligation). The hydrogel+MSCs group (G5) was compared against controls (saline, MSCs-in-saline) via serial echocardiography and post-mortem histomorphometry. In vitro, the hydrogel confirmed ideal thermosensitivity (LCST 37.1°C) and cytoprotection (2.5-fold increase in ischemic cell survival). In vivo, the G5 (hydrogel+MSCs) group demonstrated significantly preserved cardiac function (LVEF 45.2%) compared to the MSCs-only group (G4: 34.1%) at 28 days. This was correlated with significantly reduced infarct size and enhanced border-zone angiogenesis. The thermosensitive hydrogel functions as an essential, enabling technology. It solves the critical failure points of acute retention and viability, demonstrating that an engineered “pro-survival” delivery vehicle is a prerequisite for the successful clinical translation of cardiac cell therapy.

Abstract

Cultural heritage is a vital aspect of community identity and history, yet many regions face challenges in preserving and promoting their heritage in the face of modern economic pressures. Traditional tourism practices often lead to the commercialization and degradation of cultural sites, while communities struggle to benefit economically from their heritage. Augmented Reality (AR) technology offers a promising solution by providing immersive, interactive experiences that can both preserve and promote cultural heritage while supporting sustainable tourism. This study explores the implementation of an AR-based digital-preneurship start-up model designed to revitalize cultural heritage through tourism while empowering local communities. The research employs a mixed-methods approach, combining quantitative surveys and qualitative interviews with both local stakeholders and tourists. The findings reveal that the AR platform significantly enhanced both tourist engagement and local economic outcomes, increasing community participation in tourism-related activities and boosting income for local businesses. The study concludes that AR-based digital-preneurship offers a scalable, sustainable model for cultural heritage revitalization, providing communities with a new avenue for economic development and cultural preservation. This research contributes to the growing body of knowledge on the intersection of technology, entrepreneurship, and sustainable tourism.
