Abstract

Social isolation is a significant and modifiable risk factor for accelerated cognitive decline and dementia in aging populations. Traditional methods for detecting cognitive changes, such as clinical screenings, are often infrequent and fail to capture the subtle, early behavioral shifts that precede a formal diagnosis. This study aimed to develop and validate an artificial intelligence model designed for the early detection of cognitive decline by passively monitoring behavioral and vocal biomarkers of social isolation in older adults living independently. A 24-month, prospective longitudinal study was conducted with a cohort of 200 community-dwelling adults aged 70 and older. A suite of unobtrusive in-home sensors was used to passively collect data on movement patterns, social communication (frequency and duration of conversations), and computer/phone usage. The AI-powered system identified individuals who would later show clinically significant cognitive decline with an accuracy of 91% and a lead time of approximately 7 months before formal assessment. The model successfully distinguished between simple loneliness and the specific behavioral patterns of social withdrawal associated with cognitive impairment. AI-powered passive monitoring systems are a highly effective and ecologically valid tool for the pre-clinical detection of cognitive decline linked to social isolation.

Abstract

The integrity of the halal food supply chain is paramount, yet it faces significant challenges from potential cross-contamination and environmental concerns associated with conventional packaging. This review examines the critical engineering innovations at this intersection, focusing on materials and systems that ensure both halal compliance and ecological responsibility. The objective is to identify key technologies, assess their compatibility with halal principles, and highlight their potential to improve supply chain integrity and sustainability. A systematic literature review was conducted using major scientific databases, including Scopus, Web of Science, and Google Scholar. The selected literature was analyzed to identify material compositions, sensor mechanisms, and their functional applications in maintaining halal integrity. The review identifies several promising innovations, including the development of biopolymer-based films (e.g., PLA, starch, chitosan) integrated with pH-sensitive and microbial spoilage indicators. These smart systems can provide real-time monitoring of food freshness and detect potential non-halal contaminants, such as ethanol or porcine derivatives, without direct contact. The findings show a strong trend towards non-invasive sensor technologies that align with the principles of tayyib (wholesome and pure). Engineering innovations in biodegradable smart packaging offer a robust solution for enhancing the security and sustainability of halal food logistics.

Abstract

Emotionally disturbed children face significant challenges that affect their psychological well-being, academic performance, and social interactions. Traditional counseling programs often focus solely on the child, neglecting the crucial role of family dynamics in emotional development. Family intervention in counseling programs has emerged as a promising approach to addressing these issues by involving caregivers in the therapeutic process. This study aims to evaluate the impact of family-centered counseling programs on the emotional well-being of children diagnosed with emotional disturbances. A quantitative research design was employed, involving 120 children and their families, recruited from three counseling centers. Participants were randomly assigned to either a family intervention group or a standard counseling group. Data were collected over 12 weeks using validated instruments, including the Child Behavior Checklist (CBCL) and the Family Adaptability and Cohesion Evaluation Scale (FACES). Statistical analyses included paired t-tests and regression modeling to assess the effectiveness of the interventions. The results indicated that children in the family intervention group showed significant improvements in emotional regulation, reduced behavioral issues, and enhanced family cohesion compared to the standard counseling group. These findings highlight the importance of incorporating family dynamics into counseling programs to achieve better outcomes for emotionally disturbed children.

Abstract

High-precision measurements of fundamental constants have an important role in modern physics and technology. Uncertainty in measurements using classical methods is a major obstacle in improving the accuracy and validation of physical theories. Quantum metrology, which makes use of the phenomenon of quantum entanglement and superposition, offers a solution to overcome these limitations. This study aims to evaluate the effectiveness of quantum metrology in improving the measurement accuracy of fundamental constants, such as Planck's constant and Newton's gravity. The research was conducted using an experimental design with quantum sensing-based devices, such as quantum interferometers and ion traps. The data were analyzed to compare the level of measurement uncertainty between classical methods and quantum metrology. Case studies were conducted in a microgravity environment to test the reliability of this technology under extreme conditions. The results showed that quantum metrology significantly reduced measurement uncertainty to two orders of magnitude compared to classical methods. The technology has also proven to be effective in extreme conditions, providing flexibility for applications outside of the laboratory. The conclusion of the study confirms that quantum metrology is able to overcome the limitations of classical methods and has great potential to support the development of global measurement standards in the future.

Abstract

The transition to a hydrogen economy is critically dependent on the development of safe and efficient onboard hydrogen storage materials. Metal-Organic Frameworks (MOFs) have emerged as highly promising candidates due to their exceptionally high surface areas and tunable pore environments. This study aimed to combine computational modeling with experimental validation to elucidate the key structural factors governing hydrogen storage capacity in MOFs. A dual approach was employed, using Grand Canonical Monte Carlo (GCMC) simulations to predict hydrogen uptake in a series of MOFs with varying pore sizes and metal centers, followed by experimental synthesis and gas sorption analysis to validate the computational findings. The results revealed a strong correlation between the simulated and experimental data, confirming that both high surface area and optimal pore size (~10-15 Å) are crucial for maximizing physisorption. The GCMC simulations accurately predicted that MOFs with open metal sites exhibit enhanced hydrogen binding energies. This research concludes that a combined computational and experimental approach provides powerful predictive insights, confirming that tailoring pore geometry and introducing strong adsorption sites are key strategies for the rational design of next-generation MOFs for high-density hydrogen storage.

Abstract

Prostate cancer is a leading malignancy in men, where early detection is critical for effective treatment. Current diagnostic methods, such as PSA tests, have limitations in sensitivity and specificity. To develop an aptamer-based electrochemical biosensor for the early detection of prostate cancer markers, aiming to improve diagnostic accuracy and speed. The study involved the design and optimization of aptamers through SELEX, integration with electrochemical sensors, and validation using prostate cancer cell lines and clinical samples. Instruments used include electrochemical workstations, HPLC, and mass spectrometry for characterization and evaluation. The developed biosensor demonstrated a detection limit of 0.1 ng/mL for PSA, with a response time of less than 10 minutes. High reproducibility was achieved with a coefficient of variation below 5%, and the biosensor showed significant specificity and stability in detecting PSA in various samples. The aptamer-based electrochemical biosensor offers a promising tool for the early detection of prostate cancer markers, providing higher sensitivity and specificity compared to traditional methods. Further clinical validation is necessary to confirm its efficacy and reliability in broader applications.
