This study presents a mixed-integer linear programming (MILP) framework for optimizing a multimodal transportation system integrating ground mobility-on-demand (GMoD) and air mobility-on-demand (AirMoD) services. The proposed model aims to minimize user waiting time and CO2 emissions while maximizing service rates and vehicle utilization. The multimodal system is evaluated against a GMoD-only baseline across various scales and system phases, demonstrating the effectiveness of incorporating air taxis into urban transportation networks. Results indicate that the multimodal system significantly improves service rates and reduces waiting times compared to the GMoD-only baseline, particularly in medium- and large-scale networks. The integration of Yen’s algorithm within the MILP-GMoD model enhances computational efficiency of ground taxi routing. Analysis of different k values suggests that k = 2 provides a balanced trade-off between routing flexibility, cost efficiency, and computational feasibility. The findings highlight the potential of air taxis to complement traditional ground transportation, offering a scalable and sustainable solution for urban mobility.

Alzheimer’s disease is the most common cause of dementia, being a neurodegenerative, progressive disease that can be identified through different hallmarks such as tau protein buildup, amyloid plaque, and more. Through different types of molecular imaging, doctors are able to better diagnose and monitor Alzheimer’s disease. Through analyzing several different papers regarding molecular imaging’s role in Alzheimer’s disease, specifically MRI: split into fMRI and sMRI, PET: split into tau PET and Aβ PET, and SPECT imaging, the results show that molecular imaging does and can play an important role in Alzheimer’s disease, having relatively high accuracy rates for diagnosing. After thorough review of different studies, it is found that fMRI, Tau PET imaging, and Aβ PET imaging are very promising biomarkers of Alzheimer’s disease with relatively consistent high specificity, sensitivity, and diagnostic accuracy rates while sMRI and SPECT imaging results show that, although high, specificity, sensitivity, and diagnostic accuracy rates are either inconsistent or lower compared to the other molecular imaging techniques.

Video Gaming among minors can bring both enjoyment and concern. Gaming offers opportunities for entertainment, social interaction, and even skill development. However, excessive gaming among young people could lead to addiction resulting in issues like neglecting responsibilities, disrupted sleep patterns, and emotional disturbances. China has implemented the Anti-Addiction System to curb gaming addiction among minors which limits the amount of time minors can spend playing online games to promote healthier gaming habits and reduce the potential negative impacts of excessive gaming on their well-being. However, the effectiveness of China's anti-addiction system remains unknown. This study aims to examine the effectiveness of China’s Anti-Addiction System in preventing gaming addiction among Chinese youths by assessing their game time in relation to online esports spectatorship. Using an online questionnaire, this study aims to assess the potential relationship between the effects of China’s Anti-Addiction System and online esports spectatorship among Chinese youth between ages of 15 to 17 (n = 33). Data were collected on participants’ game time after restriction by China’s Anti-Addiction System and their time spent watching esports online. Additional Likert scale questions further assessed the potential relationship. The collected data was subject to linear regression analysis and statistical hypothesis tests. This study discovered that there lacks convincing evidence of a relationship between the game time influenced by the Anti-Addiction System and online esports spectatorship. Results from this study reveals that China’s Anti-Addiction System does not have a substantial influence on the online esports spectating behaviors of underage Chinese gamers. Continued research and observations in this area are necessary to develop more effective strategies for the prevention of gaming addiction among underaged gamers.

The rapidly growing world population and need for more food and agricultural knowledge has inspired city dwellers to explore urban cultivation practices such as vertical farming and community gardening. Ultra-modern approaches to growing crops and livestock in urban highrise buildings has sparked the imagination of scientists, agriculturists, and engineers as well as rural and urban citizens in recent years. With this new piqued interest for urban agriculture, secondary urban Agricultural Education programs are in a prime position for growth. However, more research is needed to inform the profession regarding quality Agricultural Education growth in American cities. The purpose of this transcendental phenomenology was to discover the essence of the shared experiences of urban students who were persistently enrolled in Agricultural Education. The findings, conclusions, implications, and recommendations associated with the study are reported as five interpretive themes of meaning including: (a) disorienting experience, (b) critical assessment, (c) shared experiences, (d) thoughtful planning, and (e) projected transformation. The essence of the shared lived experiences of Thomas High School Agricultural Education students was discovered through the lens of the Transformational Learning Theory and can be described best as a Journey Toward Transformation.
