Aerospace science and Technology 2025年 163卷

Flow control for lifting surfaces at high angle of attack is essential to increase the lift coefficient. Inspired by covert feathers of birds, a passive rotatable flap is added to the suction surface of an aerofoil to analyze its effectiveness and flow control mechanism from the perspective of fluid structure interaction. The lift coefficients of the aerofoil are measured by a balance, increasing near the stall angle and reaching maximum augmentation of 25% with the flap. Particle image velocimetry measurements show that the transition of trailing edge shear layer to vortex shedding occurs later due to the flap, and the separation zone becomes smaller, which work together to enhance the lift-to-drag ratio. Flap movement is influenced by unsteady trailing edge vortex shedding, with the flap pop-up angle increasing together with the aerofoil angle of attack and reaching a maximum value around 84∘, beyond which it decreases again. Moreover, the experimental data observes the low frequency flow pulsation and flap oscillation in addition to the high frequency trailing edge vortex shedding, which has a modulation effect on the flow fluctuation and flap oscillation magnitude. © 2025 Elsevier Masson SAS

Introduction: As a recently developed treatment modality, regeneration of the pulp-dentin-like complex via tissue engineering approaches is the focus of considerable attention. The persistence of bacteria within the root canal spaces is well known as the major challenge of dental pulp regeneration. Antimicrobial peptides (AMPs) are short peptides with inhibitory activities against a broad spectrum of microorganisms. Methods: In the present study, antimicrobial hydrogels based on 2 photo-reactive biopolymers, that is collagen methacrylate and chitosan methacrylate, and containing 2 different AMPs, that is LLKKK18 and Tet213, were used to develop a potential scaffold with antimicrobial and regenerative features. Results: The incorporation of AMPs had no significant effect on the physical, mechanical, rheological, and morphological properties of the new systems. The optimized concentration of LLKKK18 and Tet213 had appropriate antimicrobial activity against Gram-positive Enterococcus fæcalis and did not exhibit any cytotoxicity to stem cells from the apical papilla encapsulated within the hydrogels compared to the control group without AMPs. The presence of AMPs also significantly promoted migration and differentiation of stem cells from the apical papilla. In the AMP-loaded groups, greater levels of calcified nodules deposition, alkaline phosphatase, collagen type I, dentin sialophosphoprotein, dentin matrix protein 1, and vascular endothelial growth factor A mRNA gene expression, and collagen type I and dentin sialophosphoprotein protein expression were observed. Conclusions: The results indicated the potential of engineered antimicrobial collagen methacrylate/chitosan methacrylate hydrogels for application in tissue engineering-based strategies to regenerate the pulp-dentin complex. © 2025 American Association of Endodontists

Estimating the feasibility of horizontal evacuation after flooding using inundation analysis: a case study of the Kinu River floods during the September 2015 Kanto–Tohoku heavy rain

引用

City and Built Environment 2025年第1期3卷 1-16页

作者： Mizumura, Takuyou Taguchi, Hiroyuki Nakamura, Hitoshi Graduate School of Engineering and Science Shibaura Institute of Technology Saitama-shi Saitama Japan Department of Planning Architecture and Environmental Systems Shibaura Institute of Technology Saitama-shi Saitama Japan

During a flood, it is difficult to ensure safety in a vertical evacuation when the inundation depth is above the top floor level of a specific building. Thus, horizontal evacuation is important when deep inundation is expected. Some residents, triggered by the sight of rising water, begin evacuation during flooding. It is, therefore, necessary to consider evacuation behavior after the beginning of flooding, including horizontal evacuation. In the September 2015 Kanto–Tohoku Heavy Rain (15KTHR), the large Kinu River breached its levees and flooded a wide area, but flooding from the smaller Hachikenbori River may have prevented residents from evacuating. This study seeks to clarify whether horizontal evacuation following flooding is feasible in the Mitsukaido District of Joso City during the flooding of the Kinu River in the 15KTHR. The flooding was reproduced with a simulation, and analysis was performed assuming two modes of evacuation: on foot and by car. The results show that the time from the start of flooding to difficulty walking in most of the locations affected by inland flooding lasted more than 180 min, which indicates that evacuation on foot was feasible. Furthermore, the feasibility of evacuation by car was lower than that on foot in many districts, including the closed floodplains, where the time available for evacuation after inundation was shorter. Notably, evacuation by car was particularly difficult near rivers and sluice pipes, as well as in locations where the surrounding area was slightly elevated and formed a closed floodplain.

Human–robot collaboration (HRC), as an important role in intelligent manufacturing, is widely utilized in modern factories. Mobile manipulators offer greater flexibility due to the ability to simultaneously move their bases and arms. This provides them an advantage in facing challenging tasks such as flexible production and intelligent manufacturing. The environment of modern factories is complex, with slopes and thresholds at the entrance. Stability plays a fundamental role in complex environments. Therefore, for the future deployment and application of mobile manipulator in HRC, a novel dynamic tip-over avoidance method is proposed for mobile manipulators based on the extended zero-moment point (ZMP) algorithm. This method extends the traditional ZMP stability criterion into three dimensions, deriving a system-wide three-dimensional (3D) zero-moment point. The integration of the extended ZMP with redundant features facilitates adaptive weight matrix adjustments, enabling the robot to adapt its motion based on environmental constraints, thus preventing instability such as tip-over. Simulation verification is carried out withcoppeliasim. Experimental verification is performed using the MR2000 + FR3 mobile manipulator. The results confirm that the extended ZMP algorithm effectively prevents tipping in complex environments.

In order to alleviate urban congestion, improve vehicle mobility, and improve logistics delivery efficiency, this paper establishes a practical multi-objective and multi constraint logistics delivery mathematical model based on graphs, and proposes a solution algorithm framework that combines decomposition strategy and deep reinforcement learning (DRL). Firstly, taking into account the actual multiple constraints such as customer distribution, vehicle load constraints, and time windows in urban logistics distribution regions, a multi constraint and multi-objective urban logistics distribution mathematical model was established with the goal of minimizing the total length, cost, and maximum makespan of urban logistics distribution paths. Secondly, based on the decomposition strategy, a DRL framework for optimizing urban logistics delivery paths based on Graph Capsule Network (G-Caps Net) was designed. This framework takes the node information of VRP as input in the form of a 2D graph, modifies the graph attention capsule network by considering multi-layer features, edge information, and residual connections between layers in the graph structure, and replaces probability calculation with the module length of the capsule vector as output. Then, the baseline REINFORCE algorithm with rollout is used for network training, and a 2-opt local search strategy and sampling search strategy are used to improve the quality of the solution. Finally, the performance of the proposed method was evaluated on standard examples of problems of different scales. The experimental results showed that the constructed model and solution framework can improve logistics delivery efficiency. This method achieved the best comprehensive performance, surpassing the most advanced distress methods, and has great potential in practical engineering. © 2024 – IOS Press. All rights reserved.

Anomalies in motor function and social communication skills constitute early signs of autism spectrum disorder (ASD). In recent years, researchers have paid attention to the possibility of the quantitatively evaluating infants' social communication skills based on their eye movement. In this paper, we attempt to evaluate ASD risk using infants' eye movement data by examining the relationship between eye movement patterns at 4, 10, and 18 months of age and ASD risk as assessed by caregivers using a checklist at 18 months of age. A total of 18 eye movement indices were calculated from eye movement data measured by an optical eye tracker. The results revealed an association between ASD risk and eye movement indices. The indices included those related to a preference for social information at 4 months of age, those related to visual exploration of images at 10 months of age, and those indices related to both preference and visual exploration at 18 months of age. These results indicate that eye movement analysis may potentially serve as a means for early screening of ASD risk. © 2025 IEEE.

This study examines regional differences in time-varying carbon dioxide $(\text{CO}_systems)$ emissions from power systems in Denmark and Japan, influencing on the low-carbon charging schedules of electric buses in public transportation systems. The time-varying $\text{CO}_systems$ emissions differ significantly due to variations in the penetration rates of variable renewable energy (VREs) sources, particularly wind power. Numerical experiments reveal that under an optimal charging schedule, total $\text{CO}_systems$ emissions in Denmark are 81% lower in summer and 71% in winter compared to Japan when chargers are available only at their depot. Additionally, distributing chargers across all bus terminals ensures the feasibility of transportation in winter. Furthermore, distributed chargers at bus terminals have potential to reduce emissions by up to 4% further by expanding the flexibility of charging times to align with VRE utilization throughout the day. This international comparison highlights the critical importance of optimizing charging schedules in high VRE penetration systems, where $\text{CO}_systems$ emissions exhibit significant daily fluctuations.

Collaborative Marine Targets Search Algorithm for USVs and AAVs Under Energy Constraint

The collaborative search of unmanned surface vessel (USV) and autonomous aerial vehicle (AAV) for tasks with high timeliness or a large number of target points is a current research focus in the field of Marine Internet of Things technology, such as counter-mine search and data collection of ocean sensor nodes. However, the slower navigation speed of USVs cannot meet the timeliness requirements of search tasks. Moreover, AAVs have a short endurance, making it unsuitable for large-area target search missions. Combining the characteristics of long endurance of USVs and the high speed of AAVs, this article propose a heterogeneous collaborative search algorithm based on time sequence constraints (TimeSeries). Initially, a time-sliding window is designed to control the trigger time for each agent to select the next search target point. Only when the current search time of the agent is in the time-sliding window, the conditions for the next search will be satisfied, ensuring the fairness of the search. Second, considering the constraint of limited energy for USVs and AAVs, a mathematical model of energy consumption under the constraint of sea wind and ocean current environment is established, then an objective function based on energy constraint and target weight is designed. Finally, the discretized isomorphic agent collision avoidance constraint strategy and the communication radius constraint strategy among agents based on network topology are added to enhance the robustness of the cooperative system. Finally, several simulation experiments are designed and compared with other algorithms to show the effectiveness of the proposed algorithm. © 2014 IEEE.

Unpacking consumer motivations for upcycled food purchases in Japan

Food and Humanity

引用

Food and Humanity 2025年 4卷

作者： Mori, Ryota Seo, Yuna Department of Industrial and Systems Engineering Graduate School of Science and Technology Tokyo University of Science 2641 Yamasaki Chiba Noda Japan

This study examines the factors influencing consumer purchase intentions for upcycled food products, distinguishing between non-purchasers and purchasers. A comprehensive methodology was employed, beginning with questionnaire development and data collection, followed by factor analysis for each consumer group to identify key factors and reduce dimensionality. Multiple regression analysis was then conducted with purchase intention as the dependent variable and other factors as independent variables. Cluster analysis, based on factor scores representing purchase intention, was performed to categorize consumers into high, medium, and low purchase intention groups. ANOVA was used to explore socio-demographic differences within these groups. The findings reveal distinct motivations between non-purchasers and purchasers of upcycled foods. For non-purchasers with higher purchase intentions, factors such as sustainable consumption practices, curiosity, food waste awareness, and environmental responsibility were prominent. This group, which resembles early adopters, is motivated by ethical consumption and personal growth, suggesting that targeted marketing emphasizing innovation and sustainability could encourage their transition into purchasers. In contrast, purchasers prioritized sensory factors such as taste and price over product safety and quality. While they value sustainability, their purchase decisions are influenced more by practical concerns such as affordability and sensory enjoyment. Consequently, marketing strategies targeting purchasers should focus on taste, affordability, and the broader impact of reducing food waste. This study contributes to the understanding of consumer behavior toward upcycled foods by emphasizing the importance of segmenting the market based on purchase behavior. Non-purchasers are more likely to respond to messages highlighting innovation and ethical values, while purchasers are more responsive to messages focusing on sensory attributes
