Summary: An AI-based real-time prediction and control model was developed to optimize condenser water temperature and discharge air temperature set-points in a water-cooled AHU system. The ANN model, utilizing embedded MATLAB neural network objects, could determine optimal temperature set-points based on outdoor air wet-bulb temperature. Compared to the conventional fixed temperature algorithm, the ANN-based optimized control reduced total cooling energy consumption by 22%.

Summary: Climate change will increase cooling demands in buildings, affecting the efficacy of passive solutions. Building energy simulations often overlook the changing climate. In this study, updated weather files were used to reassess the impact of climate change on a hybridized heat pump system and the results showed increased cooling loads and heat build-up in the ground. However, the GSHP-NV-PCS approach remained a resilient solution with significant energy reduction potential.

Summary: Selecting the best dehumidifier for greenhouse growers is challenging due to high costs, emerging technologies, and variations in crop species, weather climate, and greenhouse sizes. This study compared the field performance of a newly developed state point liquid desiccant dehumidifier with two other commercial dehumidification technologies in ornamental and tomato greenhouses. The results showed that no single dehumidification technique was both technically effective and cost-saving year-round, highlighting the importance of combining low-cost technologies with internal dehumidification technology in cold regions.

Summary: This pilot investigation aimed to study the colonization of Candida albicans (Ca) and Streptococcus mutans (Sm) in adolescents undergoing fixed orthodontic therapy. The study found higher levels of Ca in saliva and occlusal plaque in the FOA group, while the control group had higher levels of Sm. Additionally, a disruption in the relationship between Ca and Sm was observed in the FOA group, indicating that the presence of FOAs disturbs the colonization of these pathogens in the oral cavity.

Summary: This study compares the application of modified microbial flocculants (MMFs) with conventional organic flocculants in mitigating membrane fouling. The results show that MMF has better performance in pollutant removal and membrane fouling control. The study also reveals that cake layer formation is the main mechanism of membrane fouling and MMF can reduce the accumulation of foulants on the membrane surface. Correlation analysis indicates that total phosphorus, polysaccharide, zeta potential, and particle size have the greatest correlation with fouling resistance.

Summary: This study aims to investigate the dynamic response associated with the impact of a kinetic projectile on the internal structure of an artificial satellite. Through ground damage testing and finite element dynamic simulation, we determined the lateral effect and penetration performance of the projectile, and studied its dynamic behavior when penetrating a honeycomb sandwich panel and multi-layer plates. The ballistic limit velocity of the projectile was found to be 150 m/s, and the deformation of the opening had little relationship with the projectile velocity. Additionally, it was observed that the launch velocity required to meet the damage requirements of the multi-layer plates was within 325 +/- 25 m/s, with higher initial velocities resulting in reduced damage area.

Summary: This research examines the impact of Buddhism on mergers & acquisitions (M&As) performance using data from 4622 M&A transactions of Chinese public firms between 2004 and 2018. The findings provide ample evidence that acquirers located in regions with a higher intensity of Buddhism achieve better short-term and long-term performance after the merger. Furthermore, the study reveals that state ownership plays a crucial role in mitigating this effect, and the value creation is driven by higher deal completion rates and fewer violation cases for acquiring firms. Finally, the study addresses the issue of endogeneity, and the results remain unchanged.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.
