Abstract

Pronunciation is a critical yet challenging aspect of language learning, particularly in diverse classrooms where learners come from varied linguistic backgrounds. Mispronunciations can hinder effective communication and reduce learners' confidence. Despite its importance, pronunciation instruction is often neglected in language curricula, leaving learners ill-prepared for real-world interactions. This study addresses this gap by exploring effective strategies to tackle pronunciation challenges in multilingual classrooms. The research aims to identify the most common pronunciation difficulties faced by learners in diverse language classrooms and evaluate the effectiveness of targeted instructional strategies in addressing these challenges. A mixed-methods approach was employed, combining quantitative pre- and post-tests with qualitative classroom observations and interviews. Participants included 150 learners from diverse linguistic backgrounds enrolled in an English as a Second Language (ESL) program. Targeted pronunciation exercises, including minimal pair drills and intonation practice, were implemented over a 12-week period. Data were analyzed using statistical software and thematic analysis. The findings revealed significant improvements in learners' pronunciation accuracy, particularly in stress patterns and vowel sounds. Participants reported increased confidence in speaking and greater awareness of their pronunciation errors. Classroom observations indicated that interactive and repetitive exercises were most effective in addressing pronunciation challenges. Targeted pronunciation instruction is essential for improving communication skills in diverse language classrooms.

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.

Abstract

Quantum teleportation through optical communication channels is one of the promising technologies to create secure communication systems in the future. This study aims to evaluate the efficiency of quantum teleportation through various types of optical communication channels, such as standard optical fibers, low-loss optical fibers, and free photon-based communication lines. The research was conducted using a quantitative experimental method, measuring the success rate of teleportation based on channel length, channel type, and environmental disturbances. The results showed that low-loss optical fibers had the highest efficiency, with a success rate of 85% at distances of up to 50 km. The free photon-based path shows good performance at short distances, but decreases drastically at longer distances due to atmospheric disturbances. The study also found that photon loss and environmental disturbances are the main factors affecting entanglement stability, especially in channels more than 75 km long. The conclusion of this study confirms that low-loss optical fiber is the best choice to support quantum teleportation on a local to medium scale. The main challenges in the development of this technology are the reduction of photon loss and the management of environmental disturbances. Further research is needed to address these limitati

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

Immunotherapy has revolutionized cancer treatment, yet predicting which patients will respond remains a major clinical challenge. Current predictive biomarkers, such as PD-L1 expression, have limited accuracy and fail to capture the complex interplay of cells within the tumor microenvironment. Digital histopathology, the analysis of digitized tissue slides, combined with artificial intelligence (AI), offers a novel approach to identify complex morphological patterns that could serve as more robust predictive biomarkers. Objective: A deep learning model, specifically a convolutional neural network (CNN), was trained on a large, multi-center cohort of digitized tumor slides from patients with non-small cell lung cancer who had received ICI therapy. The model was trained to identify subtle morphological features and the spatial arrangement of tumor cells and tumor-infiltrating lymphocytes. The model’s predictive performance was rigorously validated on an independent, held-out test cohort, and its performance was compared to the predictive accuracy of PD-L1 staining. The AI-powered model successfully predicted immunotherapy response with a high degree of accuracy, achieving an area under the receiver operating characteristic curve (AUC) of 0.88 in the validation cohort.

Abstract

The rapid depletion of forest ecosystems worldwide has led to an increasing need for sustainable forest management practices. One promising approach to incentivize conservation efforts is the implementation of Payment for Ecosystem Services (PES) programs. PES aims to financially reward individuals or communities who provide ecological services, such as maintaining forest cover, conserving biodiversity, and improving water quality. Despite growing interest in PES, its effectiveness as a tool for sustainable forest management remains an area of active research. This study aims to evaluate the effectiveness of PES programs in promoting sustainable forest management and enhancing the livelihoods of local communities. Specifically, the research examines the impact of PES on forest conservation practices, economic benefits for participants, and the long-term sustainability of forest ecosystems. A mixed-methods approach was used, combining both qualitative and quantitative data. Surveys were conducted with 150 households involved in PES programs across three forest regions. In-depth interviews with local stakeholders, including forest managers, government officials, and community leaders, were also carried out. Data was analyzed using descriptive statistics and thematic analysis to assess the outcomes of PES programs. The findings suggest that PES programs have led to increased forest conservation efforts, improved local livelihoods, and greater awareness of ecosystem services. However, challenges such as inadequate funding, lack of technical support, and limited participation of marginalized groups were identified as barriers to full program effectiveness. PES programs can be a viable tool for sustainable forest management, provided that they are properly funded, inclusive, and supported by strong governance frameworks. Long-term success will depend on overcoming existing challenges and ensuring equitable participation.
