Abstract Objectives: The climate crisis demands urgent action from all sectors of society, including young people in higher education. While previous research has explored individual and contextual predictors of pro-environmental behaviour (PEB), the contribution of Positive Youth Development (PYD) remains underexplored. This study investigates the relationship between PYD dimensions (Competence, Confidence, Connection, Character, and Caring) and two environmental outcomes: environmental habits and climate change awareness, considering gender differences. Methods: A cross-sectional study was conducted with a sample of 1779 students from 10 universities in Andalusia (Spain). Data were collected through an online survey assessing PYD indicators,… More >

Abstract Much of the research has focused on identifying bridge frequencies for health monitoring, while the bridge damping ratio also serves as an important factor in damage detection. This study presents an enhanced method for identifying bridge damping ratios using a two-axle, three-mass test vehicle, relying on wheel responses captured by only two mounted sensors. Damping ratio estimation formulas are derived using both the Hilbert Transform (HT) and Wavelet Transform (WT), with a consistent formulation that confirms accurate estimation is achievable with minimal instrumentation, particularly when addressing the support effect. A comparative analysis of the two More >

Abstract Wireless Sensor Networks (WSNs) play a critical role in automated border surveillance systems, where continuous monitoring is essential. However, limited energy resources in sensor nodes lead to frequent network failures and reduced coverage over time. To address this issue, this paper presents an innovative energy-efficient protocol based on deep Q-learning (DQN), specifically developed to prolong the operational lifespan of WSNs used in border surveillance. By harnessing the adaptive power of DQN, the proposed protocol dynamically adjusts node activity and communication patterns. This approach ensures optimal energy usage while maintaining high coverage, connectivity, and data accuracy. More >

Abstract The girder end restraint devices such as bearings and dampers on long span suspension bridge will deteriorate over time. However, it is difficult to achieve the quantitative assessment of the performance of the restraint device through existing detection methods in actual inspections, making it difficult to obtain the impact of changes in the performance of the restraint device on the bridge structure. In this paper, a random vehicle load model is firstly established based on the WIM data of Jiangyin Bridge, and the displacement of girder end under the actual traffic flow is simulated by… More >

Abstract The steel tube arch rib in a large-span concrete-filled steel tube arch bridge has a large span and diameter, which also leads to a larger weld seam scale. Large-scale welding seams will inevitably cause more obvious welding residual stress (WRS). For the purpose of studying the influence of WRS from large-scale welding seam on the mechanical properties of steel tube arch rib during arch rib splicing, test research and numerical simulation analysis on the WRS in arch rib splicing based on the Guangxi Pingnan Third Bridge, which is the world’s largest span concrete-filled steel… More >

Abstract Streamlined box girders serve as a prevalent choice for the primary structural elements in large-span suspension bridge designs. With the increase in traffic demands, the design of such girders is evolving towards wider bridge decks and larger aspect ratios (B/D). To obtain more effective and aerodynamic design shapes for streamlined box girders, it is essential to investigate the impact of B/D on their aerodynamic performance. Accordingly, in this study we investigate the buffeting responses of large-span suspension bridges using girders of varying aspect ratios (B/D of 7.5, 9.3, and 12.7). First, the aerodynamic coefficients… More >

Abstract Background: Maintaining optimal quality of life (QoL) is a pivotal for “successful aging”. Understanding how the QoL of the elderly develops and what role psychological factors play in its development will help improve QoL from a psychological perspective. Embedded within the lifespan theory of control, this longitudinal study aimed to (1) map the temporal trajectory of QoL among Chinese older adults, (2) examine differential effects of tripartite negative emotions (stress, anxiety, depression), and (3) test the moderating role of control strategies (goal engagement, goal disengagement, self-protection) in emotion-QoL dynamics. Method: A prospective cohort of 345 community-dwelling… More >

Abstract A steel-concrete composite cable-stayed bridge features integrated steel girders and concrete decks linked by shear connectors to support loads, but stress concentration in wet joints can lead to cracking. In-situ tests were conducted on key sections of steel-concrete composite cable-stayed bridges to analyze the stress-strain evolution of wet joints under environmental factors, constraints, and complex construction processes. The coordinated working performance of the bridge decks was also analyzed. The results indicate that temperature is the key factor affecting the stresses and strains in wet joint concrete. Approximately 7 days after casting the wet joint concrete, the… More >

Abstract The distributed permutation flow shop scheduling problem (DPFSP) has received increasing attention in recent years. The iterated greedy algorithm (IGA) serves as a powerful optimizer for addressing such a problem because of its straightforward, single-solution evolution framework. However, a potential draw-back of IGA is the lack of utilization of historical information, which could lead to an imbalance between exploration and exploitation, especially in large-scale DPFSPs. As a consequence, this paper develops an IGA with memory and learning mechanisms (MLIGA) to efficiently solve the DPFSP targeted at the mini-mal makespan. In MLIGA, we incorporate a memory… More >

Abstract Cloud computing has rapidly evolved into a critical technology, seamlessly integrating into various aspects of daily life. As user demand for cloud services continues to surge, the need for efficient virtualization and resource management becomes paramount. At the core of this efficiency lies task scheduling, a complex process that determines how tasks are allocated and executed across cloud resources. While extensive research has been conducted in the area of task scheduling, optimizing multiple objectives simultaneously remains a significant challenge due to the NP (Non-deterministic Polynomial) Complete nature of the problem. This study aims to address… More >
